Abstract: 229,815. Alderman, E. R. Jan. 9, 1924. Bobbins &c., supplying to machines.-A machine for dealing with empty bobbins which are to be used in a spinning machine whereby those that are unsuitable, by reason of their being warped ur otherwise damaged, are detected and may be separated from the others, comprises a tray or hopper 20, Fig. 1. from which the bobbins are automatically fed to a shoot 22 and deposited upon a spindle 36 similar to the spinning- spindles, normal bobbins being automatically removed therefrom and deposited in a receptacle and damaged bobbins causing the stoppage of the mechanism so that they may be removed. A conveyer 24, Fig. 4, forming the base of the hopper 20 feeds the bobbins, which 'are aligned thereon by pivoted blades 76 oscillated by a crank-disc 84, to troughs 52, so that they pass to the shoot 22, in which they assume the position shown in Fig. 7 with their heads retained in a channel portion 106. An escapement device, comprising oscillating pawls 110, 112, releases the bobbins singly, which turn about a rod 28 and are guided by the shoot so that thev come to rest upon a support 30, which is withdrawn so that they fall on to one of four spindles 36 on a rotary carrier 34. A tatchet disc 150, operated by a pawl 152 on a crank-disc 155 driven from a main shaft 74, rotates the carrier so that the spindles 36 in turn correctly register with a funnel 32, down which the bobbins fall when the support 30 is removed. The support 30 and the pawls 110, 112 are operated in correct sequence by a shaft 124 oscillated by stops on the carrier 34, and the registering of the spindles with the funnels 32 is determined by stop 162, which falls into spaced notches 168 in a disc 164 and is released to allow the rotation of the carrier by means of an arm 170 attached tr, the disc 155. Undamaged bobbins fall freely from the spindles 36 into a receptacle as the carrier is rotated, but warped bobbins that are not properly seated on the spindles and those that by reason of a similar defect fail to drop off respectively engage a detector 44 and a curved finger 48 on a lever 42, which effects the stoppage of the carrier 34 and the shaft 124. -Alovement of the lever 42 by defective bobbins causes the end 196 thereof to raise the feed pawl 152 of the ratchet gear that drives the carrier. In order to prevent choking of the shoot in the event of a prolonged stoppage of the carrier 34 the feeding- mechanism shown in Fig. 16 may be employed, wherein the bobbins are fed from the hopper to a downwardly inclined portion of a shoot 206 from which they are elevated and delivered to a portion 218, the lower end of which corresponds in shape to the shoot. 22, by a conveyer 222 provided with fingers 220. The conveyer shaft 228 is driven by chain gearing from the main shaft through a clutch, and drives the hopper conveyer by ratchet gearing and a connecting-rod 256. The clutch is automatically disconnected by means of levers 268. 274 which are operated by a link 278 connected to the lever 42 when the carrier is stopped, and by a feeler-device 304 when the supply of bobbins in the portion 218 is such that the addition of more would interfere with the movements of the fingers 220.
