Title: Improvements in or relating to horse-shoe punching machines
IPC: B21D28/32
Filed: 1921-04-21
Abstract: 183,258. Brock, J. April 21, 1921. Horseshoes.-Horseshoe blanks are punched by two sets of punches in line, their position being adjusted to accommodate variations in the blank. For this purpose the sets of punches 77, which work through guide plates 74 carried by the dies 67, are screwed into blocks 80 mounted in a transverse slot 84 in the press-head 42 and are locked by bars 82 engaging flats on the punches. Each set of punches is thus capable of endlong movement with its corresponding die, this movement being effected by positioning bars 86, which are adjustable by means of nuts 91, and carry fingers 87 adapted to engage the inner shoulders of the nail creases. The bars 86 are attached to arms 98 pivoted to a yoke 102 which is raised by a cam 106 on the main shaft 10, so as to raise the bars 86 and permit the passage of a blank. The bars are moved inwardly by a cam 111 which moves a yoke 107 carrying pins 109 which press on the outer edges of the arms 98. In operation the creased bar stock A supported on rollers 13 is fed bv a head 18 which is reciprocated on guides 17 by a link 20 and carries a gripper 28 which feeds the bar forward until released by a pin 32 riding on the rollers 13. The feed is finished by a pawl 35 pivoted to the front of the head 18 and adapted to engage notches 34 in the bar. The press-head 42 is driven by a connecting-rod 47 and eccentric 49 on the main shaft 10, which is driven by a pinon 8 on the countershaft 6, which also carries a flywheel 5<a>. The descent of the press-head first shears off a blank by means of the blade 40, delivers it on to a block 53, and flattens it under a plate 61. On the succeeding up-stroke the blank being released drops on to guide rods 64, as the block is moved away by a cam 59, and as the block returns it pushes the blank forward on to the dies 67 and holds it against a plate 66 which is raised to receive it, after being lowered to discharge the preceding blank, by a cam 118. In a modified construction shown in Fig. 19, the inner punches 142 are pressed down by a flat spring 145 and act as positioning fingers by engaging nail marks on the blank. In a further modification the dies and punches do not move endwise, but the blank is adjusted either by the action of the bars 86, or by means of a single positioning bar operated by the head 18.

Abstract: 816,943. Screw-and-nut gearing. ANDERSON CO. April 17, 1956 [June 10, 1955], No. 11636/56. Class SO (3). In screw-and-nut mechanism, particularly for raising a vehicle window 14, Fig. 1, a motordriven or hand-driven screw 18 is engaged by three roller elements 40, Fig. 2, rotatable in a carrier connected to the window 14, one of the elements being pressed against the screw 18 by a leaf-spring 50. The carrier comprises two superimposed plates 30 having central offset portions 32 providing a recess 37, Fig. 4, housing the elements 40 in spaced radial planes along the screw 18. Each element 40 has a pair of toroidal thread-engaging surfaces and has convex axle ends received in pairs of dimples in the carrier plates 30. One of the pairs of dimples 45a, Fig. 2, is elongated to allow radial bodily movement of the corresponding element 40 towards the screw 18 under the action of the spring 50. The other dimples 45 prevent axial or radial movement of the respective elements 40. The ends of the spring 50 are notched and engage tangs on the plates 30, the spring acting on the element 40 through a saddle having notched leg portions 57, Fig. 4. The plates 30 are received through an elastomeric bushing, Fig. 3 (not shown), to a flanged unit 24, Fig. 1, pivoted at 23 to a bracket supporting the window 14. The spring 50 serves to take up wear and to maintain the screw 18 and carrier plates 30 in alignment, the said elastomeric bushing distorting if necessary. The screw 18 may be replaced by a cable with a wire helix wound thereon. The screw-and-nut mechanism may actuate a vehicle radio antenna. Specifications 766,395 and 774,216 are referred to.

The initial movement to close the press is effected firstly by rams 16, 17, then by inflating bag or bellows 13 through pipe 14, both these serving to lower plate 15. Diaphragm 20 is ribbed and rubber plate 28 is ribbed or slotted to facilitate filtrate drainage. After the pressing described above, the slurry may be washed and/or dried by water, solvent or compressed air delivered either by filtrate outlet 25 or slurry inlet 24. Bellows 13 may be partly deflated and reinflated during washing. Sheet 22 is permanently clamped between rings 18, 19, but sheet 33 may be an endless belt or an extended length of material entrained round rollers 34. Parallel cylinders 37 travelling on their piston rods 36 move two rollers 34, with the press opened, and this carries one section of sheet 33 out of the press where its cake is removed by scraper 38 or by water sprays. The movement may be reversed prior to reclosing the press, or alternatively two sections of sheet 33 may be used for alternate pressings, necessitating two scrapers 38 or sprays on opposite sides. The sheets 22, 33 may be cloth, felt or paper. A manual winding drum 35 is for tensioning sheet 33.
