Drawing InstrumentsPocket Cases
This page displays the earliest sets in the mathematics collections. The coverings on the cases are sharkskin or tortoiseshell. Notable European makers crafted some of the instruments in these cases, including Pierre Martel, Michael Butterfield, Claude Langlois, and Thomas Rubergall. At least one of these sets is known to have been used in the early United States.
"Sets of Drawing Instruments - Pocket Cases" showing 1 items.
- This pocket-sized wooden case is covered with black shagreen, leather made from the skin of a shark or rayfish. On the paper lining the inside of the lid, a previous owner has written: N. O'CONNOR 2/12/1806. Ten drawing instruments were received with the case:
- 1) A 4-1/2" boxwood plotting scale with diagonal scales at each end. Above the plotting scale are scales divided to 0.12" and to 1/10". The other side has a scale of chords and architect's scales dividing the inch into 35, 30, 25, 20, 15, and 10 parts.
- 2) A 6" ebony parallel ruler with scalloped brass hinges.
- 3) A pair of 3-3/4" brass and steel fixed-point dividers.
- 4) A pair of 6-1/4" brass and steel dividers with a removable point.
- 5) A brass and steel pen point that fits the 6-1/4" dividers.
- 6) A pair of 5-14" brass and steel fixed-point dividers.
- 7) A 3" brass and steel drawing pen with a swiveling handle.
- 8) A lead pencil.
- 9) A metal joint tightener and file.
- 10) A brass gauge, unevenly graduated from 100 to 1,000 and marked "16 FT" on one side and unevenly graduated from 1,000 to 150 and marked "C 8 FT 6 IN" on the other. The first side is also marked: NEWTON & Co 3 FLEET ST NEAR TEMPLE BAR LONDON.
- William and Frederick Newton were the partners of Newton & Company, which sold scientific instruments and lantern slides from 3 Fleet Street in London from 1851 until the 1930s, when the firm moved to Wigmore Street. In the 1950s, the company was renamed Newton Photographic Services Ltd. The gauge, joint tightener, and pencil likely date to the mid-19th century. The other instruments are consistent with the 1806 date written on the case.
