Inventor: WARD ARTHUR
IPC: D05B67/00
Filed: 1911-09-04
Granted: 1911-11-16
Abstract: 19,652. Ward, A., and Gent, A. S. Sept. 4. Boot-sole sewing machines; presser-bars, locking.-A presser i is forced on to the work by a pinion c which engages with a toothed segment h on the presser-lever. The pinion receives its motion from a cam-lever f, through a spring- pressed rod g, a lever d, and a friction clutch co - axial with the hub of the lever d and the pinion. The friction clutch may be released at any time by the depression of a lever n linked to a treadle. A cam-surface on the lever engages a pin o and forces the rod g and the lever d to the right. Further depression of the lever n brings surfaces p and q together and depresses a rod r, thereby raising the presser from the work. The rod r is part of a usual thread - measuring mechanism. Fig. 2 shows a suitable clutch. Balls b are held loosely in slots j in the boss of the lever a and are jammed between recessed portions of the boss of the lever d and the bore of the pinion by the lever a, which is urged towards the left by a spring. The clutch is released when the lever d is moved to the right.
