Chinese Slide Rule using Napier Scales

REF
Chinese Slide Rule using Napier Scales (Oldest known from China)
Courtesy of Vladimir Eremeev Evstegneevich, Assistant professor of History of Science, Russian State Humanitarian University, Moscow. He claims that the date is around 1660, but other scholars of Chinese history dispute this claim.

( Gong Si He Ying) Hangzhou Stationery Factory

Note: Gong Si He Ying Factory changed its name in 1964 to Hanzhou Staionary Factory.

From William K. Robinson article in 2011
The Chinese JIANGSHI type YI (B) Slide Rule is probably the most unusual of all of those shown in my JOS listing of slide rules with hyperbolic function scales.1 It has a very different design than the other slide rules. There are numerous odd scales and marks. Also, it varies in the manner by which the hyperbolic function values are obtained. The following translation describing this slide rule was obtained from a Chinese internet site:

  • 1. The one-sided Jiang's type B slide rule is designed by Mr. Jiang Dequ (also written as: Deyao Jiang), from JIN HUA YINGSHI University, in Zhe Jiang province.
  • 2. The surface of this slide rule was printed through photomechanical process and coated with transparent plastic then stuck on the wooden slide rule. Although it is not exquisite enough and scale is not very accurate, it was the first slide rule designed and made by Chinese people between 1937 and 1945. The structure of this slide rule is rather simple, it is also easy to make and it is sold at lower price. So it was very popular with users at that time. Even during early days of the P.R.C., it was also sold in Shanghai and Hangzhou.
The actual date this slide rule was introduced and the years it was sold is not known. (note one specimen is 1960) However, if it was first sold in the year 1937 it would have been third on the list of slide rules with hyperbolic function scales. The first was the K&E Log Log Duplex Vector 4093-3, introduced in late 1929. Second was the Hemmi 153 in 1933.Full JOS Plus Article (PDF)

Shanghai Si Da Rule Factory 1083

S393
Shanghai Si Da Rule Factory 1083 - c1931
Made in China - Clone of K&E 4092-3S
Note: No adjustment screws on stock.
Front Scale: LL0, A [ B, S, T, C ] LL3, LL2, LL1
Back Scale: K, DF [ CF, CIF, CI, C ] D, L
Found in Novosibirsk, Russia. Liu Qinglin in Beijing, China identified it for me as it had no markings. At first I wondered how a K&E ended up there, but if you look at the end plates you'll see there are no adjustment screws, just 3 rivets holding the stock together. Unfortunately it did not come with a cursor, but dimensionally, a K&E will fit it. It is the same thickness, and length, but 1 mm wider, than a K&E 4092-3S.
