Abstract

327,287. Electramonic Co., Ltd., Tyrrell, S. J., Tyrrell, L. N., and Sayers, D. W. March 28, 1929. Securing tools to tool-arms.-A needle holder consists of a pair of arms 1, 2, Fig. 1, the arm 1 having a recess 3 against which the end of the needle 5 engages and the arm 2 having at its free end a notch 4 engaging the needle between its ends. The arm 1 at the end adjacent the recess 3 mav have an arm with a notched end, or a humped portion 10, Fig. 13, engaging the needle either above or below the notch 4. In a modification, channel-shaped arms 1, 2, Fig. 3, on a plate 6 and having notches at the ends, position the needle 5. The arm 1, Figs. 1 and 13, or the plate 6, Fig. 3, may form the armature of a pick-up device, and the magnetic system thereof, or a light spring, may hold the needle in position when at rest. The holder may be enclosed in a casing having a slit through which the needle can be inserted. The holder may be stamped out as a one-piece blank and then bent to shape.
