Manuals & Documentation

Keuffel & Esser, Pickett, Dietzgen, and other major slide rule companies oftentimes included an education transmission in the buy of the instrument. Some donors have provided these booklets and other newspaper items, such equally advertising flyers, directions for cleaning slide rules, warranty certificates, and even greenbacks register receipts. The Museum of Scientific discipline & Industry in Chicago previously owned and displayed one of the Thacher cylindrical slide rules, and it arrived with its exhibit label. To run across the instruction manuals alongside the objects they explained, delight see the index by makers & retailers page.

Keuffel & Esser 4013 Thacher Cylindrical Slide Dominion Exhibit Label

Description

This paper-thin sail describes a Thacher cylindrical slide rule with a magnifying drinking glass that was manufactured and sold by Keuffel & Esser of New York in the early 20th century as model 4013. (In the late 19th century, Yard&Eastward numbered the musical instrument as 1741.) It manifestly was used equally an exhibit label around 1966 at the Museum of Science & Industry in Chicago, the previous possessor of the related instrument.

Instructions for Keuffel & Esser 4013 Thacher Cylindrical Slide Rule

Description

Edwin Thacher, the inventor of the cylindrical slide rule bearing his proper noun, published instructions for using the instrument as Thacher'south Calculating Instrument or Cylindrical Slide-Dominion (New York: Van Nostrand, 1884). Keuffel & Esser of New York, which distributed and, after, manufactured Thacher slide rules, reprinted the booklet in 1903 and 1907 as Directions for Using Thacher's Calculating Instrument. This copy was printed in 1907 and sold for one dollar.

The booklet explained the processes for calculations involving multiplication, division, proportion, powers, and foursquare and cube roots. Thacher also provided solved examples for practise. He suggested "special applications" for his instrument, including conversion of weights and measures; currency commutation; pro-rating amid accounts; computing taxes, investment returns, and payrolls; and physical computations such equally mechanical power, centrifugal force, and mensuration. Chiliad&E's Improved Reckoning Car is advertised at the back of the booklet.

Ross Precision Computer Related Documentation

Clarification

Two copies of an advertising flyer for the Ross Precision Estimator, the Ross Meridi-o-graph, and the Ross Rapid Computer were received with 1996.3077.01. The flyer provides photographs and descriptions of the three instruments. Information technology also cites press releases published in Scientific American 114, no. three, January 15, 1916, and Engineering News 75, no. 21, May 25, 1916.

Also received was a short letter initialed by the inventor of these devices, Louis Ross, and addressed to Roy Kegerreis of New York City. The alphabetic character, dated July 31, 1918, notes the availability of the instruments and offers them on a trial basis. Enclosed were a 3-1/four" past 6-1/2" printed note addressed "To Men in the Army and Navy," describing the suitability of the instruments for military purposes. A second printed annotation, of the same size, appear the addition of trigonometric scales to the Precision Computer even though the price remained at $20.00.

Ross Precision Reckoner Didactics Manual

Description

This deteriorating 16-page booklet was received with 1996.3077.01. It was copyrighted in 1919, just the address "340 Sansome St." is handwritten on page three. Since the Estimator Manufacturing Visitor of San Francisco did not move to this location until 1921, the instrument and transmission were probably sent out in 1921 or later.

The transmission contains general instructions, instructions for using the punch alone, instructions for separately using the linear slide dominion attached to the instrument, hints for speed and accuracy, fundamental examples, technical details for calculating with logarithms and exponents, and practical applications from payroll to cube roots. Stamped on pages 8–9 is the text: ANOTHER HINT FOR SPEED (/) In locating reply coil, when a (/) check is desired, set slide ROUGHLY. Pages 9–16 are accessed by folding out the pages from the binding.

This 72-page salmon-colored paperback volume was received with 1981.0933.03 and 1981.0933.05. Its citation information is: William Cox, The Mannheim (Polyphase) and the Duplex (Polyphase-Duplex) Slide Rules Consummate Transmission (New York: Keuffel & Esser Co., 1920). It sold for 50 cents. William Cox helped introduce the Mannheim slide rule to the The states, invented the duplex slide dominion, and served every bit a mathematical consultant to Keuffel & Esser Visitor of New York, thus launching that house into pioneering the American manufacture of slide rules. He first wrote this manual in 1891 and revised it in 1917, calculation instructions for Grand&Due east'southward Polyphase Duplex slide rule (model 4088-iii).

A notice within the front comprehend explained how Thousand&E had updated the Mannheim line (models 4031–4056) since Cox first wrote the transmission. Cox thoroughly described the characteristics, operations, and scales of Mannheim and Polyphase (which was especially useful for problems involving powers or roots) slide rules. He provided a lengthy table of equivalents for the base scales, C and D, equally well every bit methods for working out mechanical and other formulas. He and then went through a similar discussion for the eight-inch Duplex rule (model 4065) and for the ten-inch Polyphase-Duplex rule (model 4088). A supplement by J. M. Willard of the Land College of Pennsylvania addressed the solution of problems in airplane trigonometry. Finally, there are advertisements for K&East's full general and specialty slide rules, the frameless indicator patented in 1915, a magnifier, and surveying equipment.
