K
& E / Keuffel & Esser Thacher's / Thatcher
Calculating Instrument Calculator / Slide Rule
15 Page Instruction Pamphlet All
original, not a reprint. I am not sure if this ever had a cover or not.
It is instructions and testimonials, 15 pages all told for an early Thacher
/ Thatcher calculator. I see no date, nor do I see a model number to
indicate if this predates K & E numbering their Thacher the 4100.
I think it is correct with 15 pages and was a supplemental, or quick guide,
as opposed to a full set of instructions. The condition is as seen.
Frayed w/ loose pages.

The Locke Adder
/ Patented Adding Machine This unusual sliding bar adder / calculator
was patented in 1901. Mr. Locke hailed from Kensett Iowa. It is in fine condition.
These unusual adding machines can be found marked with a second patent date from 1905 as well, and so we can assume this the first model. The adder seems kind simplistic in the scheme of things as the design of calculators and adders had been progressing rapidly by 1900 and was well advanced past this design. This probably helps explain its relative scarcity as it probably was not very popular and seemed a bit dated to many potential buyers it was offered to.
This rare antique adder is in excellent condition and show little signs of wear or tear. The main body is pressed steel with a copper flash finish. The sliding adding bars have nearly all of their original paint. The slides all function as they should. An interesting calculation device that clearly demonstrates just how far the field of calculation has come and how Iowa fits into the picture.

Thomas Edison's
Edison System Ampere Meter This Edison System ampere meter is a rare
and important piece of Electrical history. The condition of this large and
unusual Edison amp meter is exceptional. The scale reads up to 264 amps, off the scale, indicating this meter must have been
used with a huge dynamo or motor.This Edison meter measures approx. 10" across and 16" tall. The back of the case is cast iron. The etched glass face is flawless. The previous owner made a copy of the paper scale to cover the original scale to help preserve it. The original paper scale is behind the copy on the face in the pics. It is in nice condition.
The wooden case is original finish and in fine condition. The interior workings look like new. The wooden case is stamped in two places with Elec. Eng. Dept. L.S.J.U. which is Stanford University in Palo Alto CA.
A super nice and rare piece of American Electrical History that will display well and be a great addition to the old office, electrical, scientific or related collection! Nice!!

R.Fuess Berlin-Steglitz Stech - Hygrometer / Long Barometer
Moisture Tester This Long Barometer
Moisture Tester is an interesting scientific device by the well known and respected German maker R. Feuss.
It is in near mint condition and includes the original instructions - in
German. It is housed in a fitted wooden box.
The collector had the instructions translated and written out in long hand. It seems from a light reading that this device / instrument was intended to determine the moisture content or humidity inside things like bales of tobacco. Tobacco is the material mentioned in the instructions, but I assume other materials or crops that were aged and or allowed to dry out before use or processing would be suitable candidates as well.
The long tube has a series of holes in it at the bottom that open and close during the test. I remember buying a lb. of something one time that seemed a bit wet. So much so that it was about un-smokeable as it was. After two nights in a heated dry environment it lost half its weight as it dried out more. Half its weight = half its value. I imagine buying tobacco or other similar commodities by weight was much the same and this device was a way to keep one from over paying for an overly wet and heavy product.
