fullers telegraphic calculatorFullers Computing Telegraph Calculator w/  Palmers Computing Scales  It is no wonder that America was the leading power during the industrial revolution.  They had people designing, patenting, and introducing calculation devices like this one.  This unusual calculation device Palmers Calculating Scales  was light years ahead of the competition and probably led to the  introduction of many other new products and ideas.  The Palmer scale says it was first patented in the 1840's, and I guess after Mr. Fuller improved on it he included it with his own version of a circular slide rule.  Luckily he had the foresight to include with it a booklet of operating instructions   The opening blurb in the instructions claims this is "The Great Master Key Rule by Which All Problems are Instantly Solved.   I am not really sure if it could have solved Bernie Madolf's problems.  

The entire package is in very nice condition, and they are rarely seen in this nice condition any more.

Poor's Line of Position ComputerPoor's Line of Position Navigation Computer  This is a rare and interesting navigation related calculator. There are a couple of references on Google about it lamenting the fact that so few are known, and that only pictures of it can be found in a book by the inventor Charles Poor.   The face is marked Pat applied for, and it is not known if one was ever granted

This calculator is in like new condition with it original box.  The box has seen better days and the corners are torn and weak.  The instrument measures approx 12" dia. and the base is cast aluminum.  The instructions are present and in very nice condition.  It says it is a mechanical navigator for use on ships or aircraft.  At the bottom in addition to the inventor designers name, the name T.S. & J. D. Negus is given as the seller.  This was a well known outfit that dealt in all manner of navigational and nautical related devices.

Stanley Fuller / London England / Spiral Calculator / SlideruleStanley Fuller / London England / Spiral Calculator / Sliderule This Stanley Fullers Spiral Calculator / Slide rule is in nice condition. This is an example of a calculator that is getting harder and harder to find.  They were first introduced in the 1880's.  At first they were made and offered by Stanley of London a well known firm that also made the famous Thatcher calculator, and other surveying or engineering related instruments.  Later on K & E bought the rights and offered them until the end of production in the early 70's.

The serial #'s numbers on the brass scale are 6900 -37.  I believe that indicates it was made in 1937.  It has the brass external mount feature so that the slide rule can mount  for use on the outside of the box, but the mounting bracket itself is missing.  The box is pretty nice, and  is mahogany. It has a finger joint design in the corners.  It has a nice green Stanley label inside the top.  It is in overall good condition noting the remnants of another label or sticker on the outside top.

The inner scales are very nice.  It has the typical scales and charts found on these type one model calculators, and the outer scale has the typical light brown tint to it.   The scales, both in and out are in very nice condition noting just a few minor dings.  The short pointer is marked Fuller Calculator, and Made in England.  The long cursor in addition to having the date and serial number is graduated along one edge.  A nice piece in outstanding condition.

Fuller Spiral Slide Rule / CalculatorFuller Spiral Slide Rule / Calculator   The condition of this Fuller slide rule is like new / mint and came from the original owner.  These slide rules were produced in England by the W. F. Stanley Co.  The Fuller Circular slide rule was first developed and introduced in the 1870's. 

The serial # on this unusual circular drum style slide rule is 13643 /70 dating it from 1970 and very close to the end of their production nearly 100 years later.  It has been suggested in online write-ups that no more than 14,000 were made during their entire production span.  Production of this slide rule was very limited by this period and this example is one of the last few hundred made when production ceased in the early 1970's.    There were several different models produced and offered over the years.  This style would be referred to as the type 1.  Over the course of production different US companies like K & E and Dietzgen offered this rule as part of their line.  This one is just marked Stanley / England. 

The mahogany box is like new.  The original instructions are included.  The top and bottom of the rule are Bakelite and chip, crack or damage free.  The brass rod to mount it to the box for convenient use is present.  This rule is essentially new and unused.  It will make for a great addition and marks the end of an era with the introduction of electronic calculators which made the obsolete and yet created a fine collectible.   A classic!!

Fuller Calculator / Circular Slide RuleFuller Spiral Calculator by Stanley   This is an earlier model than the one above.  It does not have the external mount like the one above as the earliest models did not offer that feature.  The number on the brass scale is 109 and that number is repeated on the base of the scale.  I assume that is the serial # which would date this pretty early in the scheme of things.    There are no tears to the scales and they are pretty nice on both the inner and outer drum.   There is some very minor spotting to the scales, but the overall condition is very nice.  There is a tight crack in the box top as can be seen, and there is an early repair to it that adds a degree of character to this interesting and early calculator.   A nice piece in overall very nice condition.

Stanley Fuller Spiral Calculator / SlideruleStanley Fuller Spiral Calculator / Sliderule This is a super nice condition example.  The numbers on the brass scale are 5968 -28.   I am not sure where that would put this date wise, but it is an later model with the brass mount feature that the slide rule can mount to for use.  There is a hairline crack as can be seen in one of the pics in the wood frame, but it is just a line in the wood.  There is no damage, movement, or looseness.  The instructions are included as well.  The John Davies label inside the lid must be from the distributer, who specialized in Mining supplies as well as surveying instruments and more.  That label mentions 1933, but it is unclear in what regard.  A nice piece in outstanding condition.

Stanley Type 2 Fuller Spiral Calculator / SlideruleStanley Type 2 Fuller Spiral Calculator / Sliderule This is a  nice condition example of a very hard to find variation of a Fuller / Stanley slide rule calculator.  The numbers on the brass scale are 5836 -27.   I believe that would date it from 1927.  The finger joint mahogany wooden box has a Stanley paper label in the top, as well as a tag, from I assume, the factory it was being used in.  I am not sure what the name of that company was, but the tag says it is from the aircraft division and 54 over 14690.  The box is OK noting one latch is missing, and there are some paint spots on the top.  It does have the mounting bracket on the end of the box, and the proper bracket to mount this calculator is in the box. 

As for the rule itself, the scales are pretty nice with just a few small dings here and the typical yellowing the paper scales develop.  There is a hairline crack in the top wooden donut as can be seen in one of the pics.  It is just a line in the wood,  there is no damage, movement, or looseness.   There is also some minor staining, dirt and chipping of the paper at the top and bottom of the outer cylinder. The short pointer is marked Fuller Calculator with Scales of Sines & Logs Made in England.  This is what makes this model so unusual.   One can see the difference immediately on the inner scale as there are none of the typical tables or equations usually seen.  This inner scale is made up of 2 sets of scales from top to bottom.  A rare piece in nice condition.

Gordons 
	Addometer / CalculatorGordon's Addometer / Calculator  This is an interesting, early, and rare adder.  It is marked on the inside ring "Gordon's Addometer / Patent Applied For".  The circular body is made of Gutta Percha type plastic material.  There is a  crack in it from shrinkage.  It is stable and the calculating rings can still be rotated.   The cover is a nickel plated non- magnetic material like brass.  I believe unusual circular adder dates from the last quarter of the 19th century, and perhaps as late as the turn of the century.

A Google search turns up just one reference for the Gordon Addometer from a German site listing the name but there is no patent info or other info at that site.  Most Addometers are much later than this and there is plenty of info on those.  A Google Patent search turns up nothing for Gordon Addometer.  I tried for over an hour to find something similar and  I looked at a lot of other devices called addometers and perhaps the reason is that this design was an infringement and was never granted a Patent.  I am not sure.

I do have a bit more information from the owner.  This is one of just 4 of these that was found in an attic in New York near the New Jersey border about 20 years ago.  The parties in that original transaction surmised that the inventor had just a few of these made as pre-promotional examples, but that something then transpired that stopped the patent process and any further manufacture or development.  When these were found two were sold privately, and one was placed in the German Breker Technology Auction, where it sold in the 4K range.  This is the last one that remains, and when this one goes that is the end of them. 

Opportunity knocks.

Locke Adder / CalculatorThe Locke Adder  This unusual sliding bar adder was patented in Kensett Iowa in 1904.  This is kind of late in the scheme of things as far as the design of calculators and adders was progressing, and probably helps explain its relative scarcity as it probably was not very popular and seemed dated to potential buyers it was offered to.  This example is in Good- condition with some paint loss to the body.  The slides all function as they should.  An interesting piece that clearly demonstrates just how far we have come.

Universal Adder Patented July 15th 1890The Universal Adder Patented July 15th 1890  This unusual sliding bar adder according to the info on the front case was patented in England France Germany and Canada as well as the US on the date found on the left side of the case.  It was a well done and interesting design, with a window in the back of the unit to view the current result.  The body is made of some sort o early plastic / gutta perch a type material, and it has warped somewhat over the years, making sliding some of the scales a bit difficult to achieve.  Overall the condition is very nice otherwise.  There is also remains of a label and instructions on the back side as can be seen in the second picture.

Simplicitas
	Addizonartrice Adding Machine"Simplicitas" Addizonartrice  Despite its name "Simplicitas" this adder is anything but simple and is as complicated an adding machine as I have ever seen before.  And I should note, I have never seen this one before,  and can find no mention of it running searches on the internet or visiting several sites I know of that cover these pieces.   

As can be seen it has 9 dials mounted on a nicely finished wooden board.  It measures approx 22" long overall.  It comes in the original fabric / faux leatherette case.  Note there is one small ding in the top right corner of the back board.  Overall it is very nice though. It has its original bone or ivory pointer as well.

The layout, with a single dial to the left, and then a group of 3, and then a group of 5 with 2 above 3, must mean something, to someone, but is beyond my reasoning capabilities.  On top of that, each dial has 3 scales.  1-9 on the outside,  then another 2 different scales under the wheel with one going into at least double digits.  All of the dials are independent of each other and do not carry from one to the next. We need the instruction manual for this one, or you can spend a few minutes figuring it out.

Fowler Type H Calculator Fowler Type H Calculator  Fowler is a well known English name in circular sliderules / calculators.  This Fowler pocket watch style calculator is in super like new condition.  The original instructions are nice and included.  The outer box is tattered.  There is a small piece of plastic that was used as a magnifier.  A very nice example.

The Hart Calculator or EquationorThe Hart Calculator or Equationor  I can barely use some of the simple examples of these calculating marvels from an earlier time that I have had,  and I routinely use to flunk most of the math courses that I had to take in school,  but there must be a latent gene that drives the quest as I cannot seem to stop buying these sort of things.  Vintage calculators, slide rules, and other calculation devices are still available and it is always fun to find a different one while on the hunt.

The Rapid CalculatorThe Rapid" Calculator / Adder This is a very complicated and precision made adder / calculator.  I have only had a few over the last 20 years.  I know firsthand as my last one had a small problem carrying over, and after I got inside, and started taking it apart, I regretted it.  I am sure I voided the warranty on that one.  This example is near mint and operates just fine.  Personally though, I would buy an electronic hand held for a 1.00 and leave this one for display.

Marchant CalculatorMarchant Calculator   The Marchant Calculator company was based in Oakland Ca and began operation near the turn of the century with their non-electric pin wheel design calculators that are well known and highly collectible.  The Marchant in the Click for Pic is the black one on the right.  The condition is excellent.  The label on the back lists off all the different Patents that were designed to protect it, but Marchant is but one of the names associated with this design, so they were either selling the rights, or they were in production for a long enough time for copies to be made.   As the technology grew they moved on to electric models.  This earlier model is in very nice condition and seems to be fully operational.

"The Jeffers" Calculator"The Jeffers" Calculator   This is a very unusual and complex Agricultural related calculator.  It is in super near unused condition.  It is a wooden box that opens to reveal the calculator inside.  It measures approx 5 x7".  Inside the front door on the left side are the instructions and explanation of what you would need this for and how to use it.  Basically it is for computing just the right mixtures of feed and ingredients for livestock nutrition derived from different ratios of mixtures of different grains and meals.  Sound complicated, just try using it to see how tedious it is.    I think that pretty much explains the condition, as I would be willing to bet most of the livestock got whatever was available in the way of leftovers from the corn crop or other grain crops, and that was pretty much it.   There must be 60-70 different printed slides stored on the left which you would put into the holders on the right, and start computing the ratios, cost, weight and so forth.  I have a feeling this did not go over real big with the typical country farmer, and back then, when the farms were pretty much family owned something like this was not really needed or desired.  Perhaps today, and perhaps the Chinese should be using something like it before they add to much of whatever to the next batch of dog food, or your food.

I looked it over, and tried it out, and I can confirm it is pretty much non understandable.  That is what makes it a great collectible in the field of calculation.

"The Locke Adder"   This unusual sliding bar adder / calculator was patented in Kensett Iowa in 1901.  These unusual adding machines can be found marked with a second patent date from 1905 as well, and so I assume we can call this the first model.

This adder seems kind simplistic in the scheme of things as the design of calculators and adders had been progressing rapidly and was well advanced past this design by 1900, but I guess they had not heard that in outer Iowa and about what was going on in the rest of the world.   This probably helps explain its relative scarcity as it probably was not very popular outside of that area and seemed dated to potential buyers elsewhere it was offered to.  That old world view probably explains some of the goings on in Iowa today as well. 

This example is in excellent condition and show little signs of wear or tear.  The main body is pressed steel in a copper flash finish, and the sliding adding bars have nearly all of their original paint.   The slides all function as they should.  An interesting piece that clearly demonstrates just how far the field of calculation has come and how Iowa fits into the picture.

1st Model Wooden Case ShoeBox Comptometer Adder / Calculator1st Model Wooden Case "ShoeBox" Comptometer Adder / Calculator   The serial # on this 1st model Comptometer is 2190.  It is stamped into the metal cover over the counter area near the middle.   These early wooden case comptometers were offered beginning in 1887 and were sold through 1903.  During that period a little over 6,000 were produced.  After that the machine was cased in a metal housing.  The basic idea remained pretty much the same while going through a number of minor cosmetic changes over the years. 

There is a very informative and worthwhile site that details the history, design, operation, and other info about these machines on the internet.  It can be found at www2.cruzio.com .  This 1st Model Comptometer is listed there along with the other known wood case examples that have turned up.  Known wood case models number under 100 according to this chart.  This example came from at descendant of the original inventor / maker whose name was Felt.

All of the main keys seem to operate as they should.  There are none that are stuck. By manipulating the key strokes I can get it to zero out, but the black knob on the side which is supposed to zero it does not turn or operate.  The wooden return lever moves but does not seem to do anything.    In general when pushing the main keys it seems to carry over pretty good, except for the last column which seems to skip or overcount at times.  The main parts of the case are in Mahogany and the base appears to be a softwood like pine. The outer case is in very nice condition and looks to be original finish.  The bottom cover door is missing.   A new panel could easily be fabricated if wanted.   These wooden case comptometers only appear on the market occasionally.  Some have been known to sell in the $4000 - $6000 range, and we have this one priced to reflect the minor operational  issues mentioned above.  A rare piece that will be a welcome addition to the advanced collection of early American calculation devices

Patented Webb AddersThree Different Webb Adder / Calculators   The Webb adder was first patented near the turn of the century.  The first models were brass and mounted on a wooden board.  The next generation looked like the one on the left.  After that other versions appeared such as the Herring Calculator in the middle.  These were designed to calculator / add weights  or loads of rail cars.  It is a hard to find variation of this calculator.  Finally on the right we have what has become the norm in our lives, an unmarked knockoff that was offered at the time as the real thing.  .  Much like most of the name brand stuff you see at flea markets today, unless of course the parent company moved production there, then it is called progress or Global something.  It does not add up.  Anyway, all three of these are pretty nice, and all seem to operate.  Fill out the collection.

Marchant Type Mechanical CalculatorOdhner Style Mechanical Calculator   This mechanical calculator is similar in design and function to the American Marchant mechanical calculators made in Oakland CA around the beginning of the 20th century.  The name on this example looks to be Russian or some other Cyrillic language and it may be an Odhner which have similar features like the wingnut zeroing knobs this one sports.  Odhner calculators were first made in Russia in the 1870's after which production was moved to Sweden.  There are many other brands or makes of mechanical calculators similar to this as it was a popular design that was produced worldwide well into the 20th century.  It is functional and not bound up or jammed.  The overall condition is very nice!!

Burkhardt Type A ArithmometeA. Burkhardt Type A Arithmometer   This early stepped drum adder / calculator is in nice overall condition. From its features and low # 72 serial number It would be a first model called the Model A produced in the 1870's.  The basic design of this style calculator was first designed over 100 years earlier and there are numerous bios on the inventors and histories of this style stepped drum calculator called and Arithmometer that can be found on the internet.  I read the original design was developed by Liebniz.  Mathias Hahn & Thomas de Colmar created versions of their own design after Liebniz.  A. Burkhardt was German and is credited with being the first in Germany to produce them.  Over the years he produced several different models with this style being the earliest. This same basic design calculator can be found with several other names from different locals as well. 

This example wants to work, but does not work properly or consistently. I believe it is just an adjustment.   I see do damage, bent pins, missing parts or the like on the underside.  It will work for small amounts, and sometimes for larger ones, but then will hang up.  It zeros out and the carriage moves OK.  Also the division function works - - - - sometimes.  On the left the small framed slate board is missing over the open hole.  There are also 2 of the miniature thumbscrews missing from the first two digits on the upper far left.  You can see this in the pics.   

A rare and unusual calculating machine, especially being the early model with such a low serial number.  Worthy of inclusion in any collection with a focus on Office antiques, calculation, or technology advancement.

Calculus CalculatorThe Calculus Calculator   This is a calculator I have never seen or had before.  This unusual dial / drum type calculator claims it was patented on January 22nd 1907.  It also has the maker name James J. Hinde Co. of Cleveland O. on the side.  The catchy logo / phrase under the name reads "Proves as it Calculates".

I could not find the patent with Google Patent Search.  I did find an ad in a lumberman's magazine touting it usefulness for use in that field or trade.  A few other references to this calculator can be found on the internet, but scant examples are pictured or discussed.  The internet site that deals with office antiques like pencil sharpeners, staplers, and the like also has an ad for one of these showing  the user sitting in front of a larger and what looks to be ganged together unit.  The dimensions of  this stand alone Calculus Calculator unit are 4 x 5 x 18".  Note the folding leg / stand that angles it for easy use.

It looks as if it is meant to calculate the price of multiple units.  The rotating drum is broken down into 1/4 increments starting at one and going up to 80, or maybe 100.  The columns are the top number added to itself over and over again in different ways   A lot of it makes no sense to me, and I have provided numerous pics below to help you determine just what it is capable of doing.    Different!!

1st Model Comptometer w/ Fractional Keys Wooden Case / Shoe Box Style1st Model Wooden Case / Shoe Box Style Comptometer w/ Fractional Keys  The serial # on this 1st model Comptometer w/ fractional keys is 5539.  It is stamped into the metal cover over the counter area between the 4th and 5th window.  These early 1st model wooden case comptometers were offered beginning in 1887 and were sold through 1903. During that period a little over 6,000 were produced. After that the machine was cased in a metal housing. The basic idea remained pretty much the same while going through a number of minor cosmetic changes over the years.

There is a very informative and worthwhile site that details the history, design, operation, and other info about these machines on the internet. It can be found at www2.cruzio.com . This 1st Model Comptometer is not listed there with the other known wood case examples that have turned up. Known wood case models number under 100 according to this chart and just a couple have fractional keys. Doing the math, it can be assumed that one, very few comptometers were made with fractional keys, and 2, that even fewer have survived. 

All of the main keys seem to operate as they should. There are none that are stuck. By manipulating the key strokes I can get it to zero out.  Beyond that it is not tested.   The main parts of the case are in Mahogany with its original crusty finish. The base appears to be a softwood like pine and the bottom door is present.

These wooden case comptometers only appear on the market occasionally. Some have been known to sell in the $4000 - $6000 range.  This 1st model fractional key comptometer is rare piece that will be a welcome addition to the advanced collection of early American calculation devices.  Very Nice!!
