Title: Improvements in or relating to clamps
IPC: D06F55/00
Filed: 1961-08-19
Abstract: 1,021,232. Clamps. T. A. BOURN. Nov. 13, 1962 [Aug. 19, 1961], No. 29994/61. Heading E2B. A clamp comprises an attachment member 10 or 40 including a planar abutment surface for engaging an upright surface of a support member and a planar guide surface fixed in position and inclined relative to the abutment surface a pair of jaws of which at least one is movable relative to the attachment member, the movable jaw or jaws being in contact with the guide surface during such movement, a slot 16 or 45 formed in the attachment member which is open at one end to receive an article to be gripped between gripping portions of the jaws and biasing means acting on the movable jaw or jaws to urge the gripping portions towards one another, the arrangement being such that the weight of an article gripped by the jaws provides a component of force tending to move the jaw or jaws along the guide surface to bring the gripping portion of the jaws together. In a first form Figs. 3 and 4 the attachment member 10 has a vertical back wall providing the abutment surface 11, the wall having screw holes by which the clamp is secured to the support. The member 10 also has a horizontal base 13 and a curved front 14. The slot 16 opens both in the front 14 and in the base 13. In the underside and vertical back wall of the attachment member is a cavity 19 which has slideway grooves 22 opening on to the surface 11. The grooves 22 receive a closure plate 25 and on the plate in the cavity is a pair 27, of said jaws each of disc form, a pressure member 29 and the biasing means which is a leaf spring 31. The cavity in the attachment member is formed with portions 23 of its side walls which converge towards the front of the member and the pressure member pushes the two jaws along the wall portions 27 until they contact each other. A sheet or blanket inserted between the jaws forces them apart. The jaws can have a roughened or serrated circumferential edge and can be made of a synthetic resinous material. In a second form Figs. 6 and 7 the attachment member of the clamp is substantially V-shaped in cross-section to provide a vertical limb 41 which provides the planar abutment surface and a downwardly inclined limb 43 which is provided with the slot 45 and the underside of which forms the planar guide surface. Pivotally mounted on the limb 43 is a pair of said jaws which are urged by the biasing means, which in this form is a pair of springs 52, against stops 54. The gripping edges 50 are formed eccentrically relative to the axes of the pivot pins 48 and are serrated. In both forms only one movable jaw may be provided, the other jaw in such case being an edge of the slot.

Title: Bearings and bushes
Inventor: KNOBLAUGH ARMAND FRANK
IPC: G10C3/16
Filed: 1951-12-27
Abstract: 707,111. Bearings. BALDWIN CO. Dec. 27, 1951, No. 30238/51. Class 12(1) [Also in Groups VIII, XXV and XXXVIII] A bearing assembly comprises a holder having a hole therein and, fitted in the'hole, a bearing bush comprising a tubular sleeve fabricated from flexible strands and rigidified by a superficial cementitous coating which penetrates only partially into the sleeve so as to leave the inner portion thereof free of the coating. In one embodiment nylon strands in the form of either cords, thread or yarn, are braided into a tube 1, Fig. 2, which is tensioned longitudinally to reduce its diameter and is passed between brushes 4 which apply to it an exterior coating 3 of nitro-ecllulose lacquer cement. A pair of stiffened tubes 5, Fig. 4, are pushed from either side with a rotary motion into bearing holes 7 in the respective ends of a bifurcated hinge member 6 which constitutes the support for a centre pin of a pianoforte action and is preferably made from wood with the grain extending transversely to the holes. The tubes on reaching the inner ends of the holes are trimmed off by rotary knives 81. Members 9 apply solvent to the exteriors of the tubes to soften the coating, so that the latter on subsequently hardening will adhere to the interior of the bearing holes. In a modification the strands are braided around a core wire which is made from an alloy of lead and tin, and has a diameter slightly less than that of the corresponding centre pin. The tubular assembly 24, Fig. 8, so constituted is drawn through a coating bath containing liquid cement 31; passing successively through aligned holes 25, 26, 27 in dies which divide the bath into a pair of compartments 28, 29. Hole 25 is a close fit to prevent leakage of cement, hole 26 serves to brush the cement into the outer strands and hole 27 regulates the thickness of the coating. In a further modification the stiffened tube 32 issuing from the bath is passed through a final die which shaves the hardened exterior to the required diameter. After the tube is pushed into a bearing hole and trimmed to length the core is ejected by means of a punch which is lubricated with soap solution, the latter being deposited on the inside of the bush to form, upon evaporation, a lubricant for the pin. The core wire may be moistened with soap solution before the strands are braided thereon. The strands may alternatively be of wool, silk or rubber.
