Abstract

733,501. Claw clutches. REGINA SEWING MACHINE CORPORATION. Jan. 5, 1953 [Feb. 26, 1952], No. 235/53. Class 80 (2). [Also in Group VII] In a sewing-machine an electric motor 17, pivoted at 18 in the frame 1 of the machine, drives a hand-wheel 3, rotatably mounted on a main shaft 2, by means of the frictional engagement of a driving wheel 19 on the motor spindle with an annular groove 6 in the handwheel concentric with the shaft 2. The rotation of a knurled wheel 7, mounted on the hand wheel, in one or the other direction, serves respectively to transmit rotation of the latter to the shaft, or to disengage the driving connection therebetween. The hand wheel is retained on the end of the shaft by screws 4 anda ring 5 which engages a shoulder formed on the shaft. Mounted within the hand wheel is a bobbin-winding device comprising an externally screw-threaded portion 12 engaging an internal screw-thread in the knurled wheel, a winding pin 14, radial pins 11 disposed in longitudinal grooves 15 in the hand wheel, and a guide-pin 9 disposed in an axial bore in the shaft. Rotation of the knurled wheel in one direction retracts the winding device into the hand wheel to engage clutch members 13, 16 formed on the winding device and shaft respectively to drive the latter. Rotation of the knurled wheel in the opposite direction disengages the clutch members and projects the pin 14 from the hand wheel. It is stated that the wheel 19 may alternatively be applied to the inner concentric surface of the groove 6.
