Title: Improvements in grinding or abrading machines
IPC: B24B5/35
Filed: 1928-02-23
Abstract: 304,060. Hushes, V. A. B., (Cincinnati Grinders, Inc.). Feb. 23, 1928. Balls, shaping and surfacing.-In a grinding machine, the work pieces are presented to opposed grinding and regulating wheels by means of a rotating carrier which steadies the workpieces but allows freedom for their automatic adjustment on the work rest and the periphery of the grinding- wheel. The grinding-wheel 10 has a periperal arcuate groove 11 and the regulating wheel D is mounted on a slide C adjusted by a screw E which is connected by lever mechanism G to a rotary cam 12 to impart reciprocating movement to the regulating wheel in order to feed the blanks to the grinding-wheel. A slide I mounted beneath the slide C carries a bracket 13 provided with a work-rest 14 which projects between the grinding and regulating wheels and supports the spherical heads of the work-pieces 15 during the operation. The grinding-wheel rotates downwardly toward the work-support while the regulating wheel is moved slowly upwardly to rotate the work by frictional contact. The work carrier comprises a disc 23 rotating on a spindle 21 and provided with peripheral openings 24 to receive the shanks of the work-pieces. A plate 25 has a flange 26 which limits the movement of the workpieces into the sockets. Intermittent movement is imparted to the carrier to bring the work-pieces successively into position by means of a ratchet wheel 27 engaged by a pawl 28 which is rocked through lever mechanism, Fig. 4, from a rock shaft 33. The indexing movement is effected at the required time by means of a lug on the cam disc 12, which coacts with a rack rod and pinion to actuate the shaft 33. The cam disc is driven through a belt 43 and worm gearing 42 from a motor 44. The finished work-pieces are ejected by means of a member 46 actuated by an arm 50 on a rock shaft 51. This shaft is operated from a lug 58 on the cam disc 12 through a lever arm 54 and a trigger device. The ejecting movement may force the finished work-piece into a discharge tube 60, whence it may slide out of the machine. In a modification, Fig. 7, the work carrier is fitted with positioning bushes 61 having a portion 62 which fits the shank of the work-piece and a recess 63 to receive the ball end. In this case the ejector forces the ball end into the recess 63, after which the carrier is indexed. When the work-pieces reach the bottom of the carrier they fall out by gravity into a suitable receptacle.

The coupling comprises a spigot 11 on the tractor 2 and a socket 10 on the end of the pipe 8 with a spring biased sleeve 17 operating locking balls 14 by means of an inwardly extending bead 19 to move the balls into a groove 15 in the spigot. A cable, wire or chain 22 is attached to the sleeve 17 and to the changeover member 25 on the trailer. If the trailer 3 breaks away, at first the cable 22 pulls the member 25 to operate the trailer brakes, then the spring 18 biasing the sleeve 17 is compressed to allow the balls 14 go be released from the groove 15 and thus allow the coupling to come apart. In a modification, the pipe 8 extends from the tractor 2, with the spigot on the end engaging with the socket and the sleeve as before. Here, the socket is directly coupled to the changeover member 25, so that upon break-away the socket is initially pulled by the pipe to operate the member. Then the sleeve contacts an abutment on the trailer to release the coupling. In a further modification a coupling part on the pipe is held in the coupling part in the tractor 2 by segments locating on a thread and having hexagonal exterior surfaces held in a sleeve extending from the tractor. Upon break away, the pipe 8 pulls the coupling parts out from the tractor against a spring and operates the change-over member, until the segments extend from the sleeve so that they part from the thread to release the parts.
