Abstract: 22,196. O'Connell, J. Oct. 20. Burnishing; paring and abrading; uppers.-A machine for beating-up the heel seats and toes of lasted shoes prior to fixing the sole and heel comprises a corrugated beating-up wheel 27 and two disks 38, having corrugated peripheries which overlie the ends of the wheel 27, and means for rotating all three simultaneously. The wheel 27, an auxiliary beating-up wheel 28, a buffing-wheel 29, and a polishing - wheel 30 are mounted on an horizontal shaft 24 in bearings towards the front of a table 1. The disks 38 are each fixed at the head of inclined shafts 36, and are arranged for adjustable resilient movement in the direction of the length of the wheel 27. They may also be adjusted forwards or backwards. Each shaft 36 is mounted in a bearing 35 held in a frame 31, its lower end being supported in a bearing in the frame itself. Each shaft carries a friction-wheel 40 adapted to engage the face of one or two disks 9. Each frame 31 is mounted so as to slide laterally on a rod 44 and is adjustably supported by a nut Q on a pin 49, which is also arranged to slide laterally on a rod 51 supported at its centre from the table 1 by a screwed rod 52 and a nut 54. Springs 55 hold the frames against the nuts Q, which may be used for adjustment. By operating the nut 54, the position of the disks 38 may be adjusted even while the machine is running. The friction disks 9 are attached to collars 7 and are loosely keyed to a shaft 4, on which is a flange 10 between the disks. Compression springs 11 are arranged between this flange and each friction disk to maintain contact between the friction disks 9 and the wheels 40. The collars 7 are grooved, and are engaged by forked projections 32 from the frames 31. The normal distance between the disks 38 is adjusted by means of sleeves 42 screwed into the frames 31 and having flanges 43 by which they may be operated. A compression spring 45 maintains these flanges apart, and springs 47. fixed by means of adjustable collars 46, act on the outer ends of the sleeves 42, tending to resist outward movement of the disks 38 when in operation. Power is supplied by a pulley &c. 5 to the shaft 4, which is arranged to drive a second shaft 12 from which are driven the shaft 24, carrying the roller 27, and a short shaft 19, carrying an emery wheel 22, towards the rear of the table 1. The disks 38 simultaneously receive their motion from the friction disks and wheels 9, 40, which friction disks follow the movements of the disks 38 by reason of the forks 32 on the frames 31 and the springs 11. In operation, the toe or heel is passed between the disks 38 and over the wheel 27, the corrugations rapidly beating the upper into shape. The wheel 28 is intended for operating on certain parts of the toe, and is made in sections to enable one portion to be replaced by a narrow disk A, Fig. 7, when it is decided to polish or beat up the edges of uppers which are attached to a welt, the disk A entering between the upper and the welt. Should the leather at any part form a bunch, in being beaten up, the surplus material may be removed by the emery wheel 22.
