Filed: 1947-12-16
Abstract: 632,905. Cloth-cutting machines. BELLOW, A. Dec. 16, 1947, No. 33076. [Class 31 (i)] In an electrically driven cloth-cutting machine wherein the motor spindle is provided with a hand wheel, Fig. 1, for adjusting a vertically arranged reciprocating cutting knife (not shown), the hand wheel is capable of freewheeling upon the motor spindle so that it does not rotate when the machine is in use. The connection may be through a free-wheel device or a one-way friction clutch. In the example the hand wheel comprises a disc 2 with a collar 3 which accommodates a rotor 4 which can revolve freely within the collar. A bolt 7 secures the rotor to the motor spindle and when these are rotated, roller bearings 6 in recesses 5 in the rotor are carried in a clockwise direction by the walls 11 of the recesses and the hand wheel is free. In order to raise the cutting knife to its highest position, e.g. for sharpening, the hand wheel is turned in a clockwise direction, thus locking it to the spindle through the bearings 6 which are thrust against the collar 3 by the walls 13 of the recesses 5. The body of the hand wheel is formed by a cover-plate 12 suitably fixed to the disc 2.
