* Circular rules work on the same logarithmic concepts as straight rules, but the actual physical operation is sometimes not so simple to understand due to the construction. To help you puzzle out these rules, we are posting the original manuals here as we find them.
* Circular rules were made by Concise, Faber-Castell, Pickett, Gilson, Fearns and others. Each maker had their own scale techniques and different construction methods. Some used rotating disks, some single, some (like Gilson) dual cursor arms with clutches, and they existed both as simplex and duplex designs. Because of the different construction methods, each rule's operation is slightly different, and needs a bit of explanation as a result.
This information was freely distributed with new rules, but note that it is copyright by the respective companies. GILSON rules were usually marketed under other names like Lietz, POST, Dietzgen and so on, and the rule does not even have Gilson's name on it. The company was located in Florida, and made some of the most interesting US circular rules.

INFO / SCALES

GILSON
Atlas/Binary
Gilson Atlas/Binary
 *8 Inch Duplex Circular

Gilson's most famous aluminum circular slide rule, with alternating yellow/white stripes and fractional converter/operator scales. This rule was made by Gilson in Florida (copyright 1931/1940), but was often sold by numerous other companies under their name, such as Lietz, POST, etc.

This is a very powerful rule, with 3 sets of trig scales (sin/tan), giving performance equal to a much larger straight rule. Coupled with the degrees/minutes format, this high resolution is ideal for navigation or other survey uses.

Has many unique scales such as drill and thread plus fractional 'binary' scales that permit operations directly with fractional numbers. Rotating dual cursors/clutch on one side, single cursor on other.
