Abstract
188,000. Fell, S. H. April 22, 1921. Slotting.-In a machine for slotting the ends of textile bobbins, tubes, &c., the blanks are automatically fed into the machine, slotted in two directions at right angles and ejected. The blanks are fed down a shoot 1, engaged by fingers 2 and fed forward by a slide 3 into line with spindles 4, 5. The slide is operated by a cam 8 and bell-crank lever 6 and controlled by springs 7. The spindle 4 is threaded in a sleeve rotatably mounted in a headstock 19, and is axially adjustable by means of a nut 20, secured to the sleeve, to accommodate blanks of different lengths, and carries sharp feathers 21 for engaging the inside of the blank. The spindle 5 is supported by a stationary tail-stock 29, and is slotted to receive a saw 30, driven by a belt pulley 32. The head-stock is slidably mounted on the machine bed, being reciprocated by an eccentric cam 28 on a shaft 12 to cause the blank to be pressed against the saw. On the next withdrawal of the blank, it is rotated through 90‹ by means of a pawl and ratchet worked from a cam (not shown) and a spring-pressed spacing plunger. Another cut is made in the blank, and it is then ejected by an arm 33 operated from a cam 34. The machine, is in duplicate on each side of the cam 28, so that one head-stock is advancing while the other is receding. The machine is started and stopped by means of a clutch 17 worked by a handle 18.
