Title: Improvements in guillotines
IPC: B26D7/02
Filed: 1920-01-03
Abstract: 164,405. Hooker, Ltd., P., and Donnison, A. P. Jan. 3, 1920. Guillotine type.-In guillotine machines for cutting paper, &c., the clamp for holding the material to be cut is operated directly by the knife-carriage through a pin thereon engaging an inclined slot in the clamp. Movement is imparted to the knife-carriage by cranks having differing throws, and a second spring-supported clamp is provided below the main clamp to allow the position of the work to be determined with regard to the knife. The operating-shaft is driven by spur and worm gearing through a friction clutch which is opened at the end of a revolution by a cam on the shaft. Disabling means for the clutch may be provided. The knifecarrier 2 moves in slots 2a in the framing, and is mounted to slide on a rod 3 reciprocated by slides 4 from eccentrics 12. To allow for angular displacement of the bar 3 owing to the differences in the throws of the cranks one slide 4 is connected thereto by a pin and slot. A pin 7 on the knife carrier 2 engages an inclined slot 8 in the clamp 6 which moves in grooves 6a in the framing and is serrated to allow the similarly-shaped back fence 34 to be brought close up. Supported by springs 30 below the clamp 6 is a false clamp 29, Fig. 9, which can be lowered on to the material by a pedal 31 through link and lever connections. Springs secured at one end to the framing and at the other to the knife carrier 2 serve to increase the pressure on the clamp during the down stroke, and assist the return of the knife carrier on the upstroke. The main shaft 17 is driven by spur gearing 15,14, Fig. 4, from a shaft 16 through worm gearing 18, 17, the worm being feathered on the drum shaft 19 to allow longitudinal movement thereof. The lever 51 operating a friction clutch 22, is rocked by a link 50 (Fig. 8), through a cam 26 on the driving-shaft 13 to open the clutch through a lever 46 connected to a second lever 48 through a hand-lever 27 pivoted thereto, and fixed over the lever 46 by a spring 49. Depression of the lever 27 effects the restarting of the machine, and lateral movement thereof permits more than one revolution of the driving-shaft to be made. A modified form of support of the clamp 6 by means of links is described.

Title: Apparatus for winding tire beads
IPC: B29D30/48
Filed: 1958-01-03
Abstract: 855,920. Tyre bead cores. DAYCO CORPORATION, [formerly DAYTON RUBBER CO.]. Jan. 3, 1958 [Jan. 29, 1957], No. 348/58. Classes 144 (1) and 144 (2). Tyre bead cores having sloping radially inner peripheries, for use particularly in tubeless tyres having tapered bead feet, are formed by winding the wire strands 13 of the core on a mandrel 10 having a sloping peripheral winding surface 11, the windings being prevented from slipping off the surface 11 during formation of the core by a series of circumferentially spaced retractable retaining bars 17 which are disposed radially on the small diameter face of the mandrel 10 to project radially beyond the radially inner edge of the winding surface 11, the bars 17 being retracted automatically on operation of ejector means 16 to permit the ejection of the wound bead core from the surface 11. As shown, the mandrel 10 comprises a circular disc rotatably mounted on an axial shaft 12 and having a flanged periphery providing the sloping winding surface 11. The retaining bars 17 are slidably guided in radiallyaligned lugs 34, 35 of guide blocks 31 which are about the disc face, the bars 17 being urged radially outwardly by springs 41 and having a sloped or bevelled radially outer end surface 39 to facilitate bead ejection when in their retracted position. Each bar 17 is associated with a C-shaped ejector arm 16 pivotally mounted at one end on the opposite face of the mandrel so that its other end 18 will sweep across the winding surface 11 when the arm is rocked about its pivot 20. Such rocking of the arms 16 is effected by a pusher-plate 23 carried on a sleeve 24 slidably mounted on the shaft 12. Each arm 16 bears on one end 27 of a push-rod 22 which extends slidably through a bushed axial aperture 28 in the disc 10 so that its other end is aligned with a transverse aperture 37 in the associated bar 17. The aperture 37 has a radially inner wall which is sloped so that on projection of the rod 22 through the aperture 37 the bar 17 is carruned radially inwardly thereby to retract its end 39 flush with the winding surface 11. Each rod 22 is urged towards its associated ejector arm 16 by a spring 25 and the throw of the arm 16 is such that, on operation of the plate 23 to eject the bead core, the rod 22 will be projected to effect retraction of the bar 17 before the ejector arm end 16 contacts the bead core.
