Title: Method of and means for automatically carding belt fastener hooks
Inventor: HISCOCK ROGER FREDERICK
IPC: B65B15/04
Filed: 1965-01-22
Abstract: 1,070,681. Packaging belt fastener hooks. STEELACE Ltd. March 30, 1966 [Jan. 22, 1965], No. 2835/65. Heading B8C. A machine for carding belt fastener hooks comprises means for feeding the hooks in two opposed streams towards each other either having the longer limbs of the hooks in one stream and the shorter limbs in the other stream on the same side of the path of travel if hooks with unequal length limbs are used or having hooks in one stream larger than those in the other, if equal length limbed hooks are used, means for feeding a length of card beneath the ends of the streams, the card having three series of transverse slots therein, into which the hooks are pushed by means operating transversally of the streams, with their apices through the central row of slots (331), Fig. 1 (not shown), and means for bending the card into trough-shape, the shoulders of the hooks being thereby projected through the outer series of slots (332). The hooks 20 to be carded on the card (33), Fig. 1 (not shown), are arranged on the members 211, 212 and are fed towards a central gap by blocks 23 moved by weight-loaded belts 24. The gap has a central partition (28), Fig. 9 (not shown), on each side of which there is a Y- shaped plate (29) defining gaps (A 1 ), (A 2 ) between the partition (28) and the plates (29). The hooks 20 fall off the members 211, 212 into the gaps (A 1 ), (A 2 ) and are restrained there by the enlarged leg (291) of the plate (29). A fixed structure 26, which is mounted adjacent the gap, has a cross-bar (262), Fig. 4 (not shown), through which rods (31) are reciprocable. The rods (31) have an upper cross-member (311) to which a pair of blades (32) is fixed. As the blades (32) descend into the gaps (A 1 ), (A 2 ) they push the hooks 20 into the central slots (331), moving the plates (29) outwards against spring bias (30), Fig. 9 (not shown). A comb 37 is raised by a wheel (36), Figs. 4 and 6 (not shown), as the blades (32) descend, the cards 37 having recesses (371) to receive the apices (201) of the hooks. Adjacent the structure 26, in the line of travel of the card are a pair of bending fingers 39, Fig. 5 (not shown). The fingers 39 have recesses 39a in their upper ends which receive the shoulders of the hooks after the cards have been bent by the fingers into a trough-shape and the shoulders project through the outer row of slots. The fingers are slidably mounted on a horizontally reciprocable carriage 40. The lower ends of the fingers 39 each have a roller 391 engaging a vertically reciprocable plate 392 movable with the carriage 40. When the fingers 39 engage the shoulders of the hooks, the carriage 40 is moved to the right. A cutting wheel 41 is mounted to move upwards and to be brought into rotation at given intervals. The wheel 41 is driven electrically from a motor 62 by a ratchet means, Figs. 10, 11 (not shown), driven from the machine cam-shaft 42. The intervals may be adjusted to allow various lengths of card to be cut off.

Abstract: 808,429. Building tyres. FIRESTONE TIRE & RUBBER CO. Jan. 30, 1956 [Feb. 28, 1955], No. 2880/56. Class 144 (1). In building tyres, tyre bands of elastic material, such as a tread and sidewall band 12 and a tyre carcase 10, are superimposed by spinning the tread about its axis to cause it to expand centrifugally into contact with an external sleeve support 16, Fig. 5, spinning the carcase 10 about its axis on a drum 11, telescoping the sleeve 16 over the drum 11 and then reducing its rate of spin to allow the tread 12 to shrink elastically on to the carcase 10, Fig. 7. As shown the tread band 12 is sleeved or spliced on to an auxiliary drum 17 rotatably supported cantilever fashion on a shaft 19 at one end of a frame 24, 25, and the carcase band 10 is built up on a collapsible drum 11 supported for rotation at the other end of the frame. The sleeve support 16 is mounted for rotation in a pair of ring bearings 27, 28 supported on a carriage 32 which is slidable on guides 58 from a position intermediate the two drums 11, 17, to positions where the sleeve support surrounds either of the drums. This sliding movement of the carriage is effected by a lead screw 52 driven by a reversible motor 55 and engaging a nut 51 on the carriage. Rotation of the sleeve support 16 is effected by a ring gear 36 thereon driven by a motor 33 on the carriage, the motor shaft being extended to carry the inner member 39 of a pneumatic clutch arrangement the outer part 41 of which is mounted on the frame 24 and drivingly connected by a chain 44 and sprockets 45, 46 with the auxiliary drum shaft 19. The arrangement is such that when the sleeve 16 is telescoped over the auxiliary drum 17, the clutch members 39, 41 are engaged by inflating the clutch tube 48 and the drum 17 and sleeve 16 are synchronized to rotate at the same speed. For exact location of the tread band on the auxiliary drum 17 and in the sleeve 16, the drum 17 has radial flange 61 at one end, and the inner surface of the sleeve is contoured to complement the outer surface of the tread band. The tread band is formed initially with an inner diameter slightly less than the external diameter of the carcase to ensure a snug fit, and suitable stitchers may be used to consolidate the tread on the carcase after their assembly.
