Abstract
27,177. Myers, L. Nov. 26. Compasses.-A spring clip for holding a pencil &c. on a pair of compasses comprises a pair of arms 7, 8 secured to the base 4. The arms are normally inclined to the axis of the pencil 9 and have holes 2, 3 which are of slightly larger diameter than the pencil and through which the latter passes. By pressing the arms 7, 8 together, the pencil can be adjusted or withdrawn and a fine screw-thread can be cut on the pencil, to allow of screwing adjustment, by rotating it within the clip. The clip is secured to the leg 1 by forming it with two lateral projections 12, 13 which are closed round towards each other and are adapted to grip the end 14 of the leg 1. The base 4 may, in addition, have a small indented pip 15 engaging a hole in the part 14.
