Title: Improvements in or relating to plain bearings
Inventor: LOVE PHIL PRINCE
IPC: F16C33/12
Filed: 1952-09-26
Abstract: 732,249. Making composite bearings. GLACIER METAL CO., Ltd. Sept. 28, 1953 [Sept. 26, 1952], No. 24176/52. Classes 83 (2) and 83 (4). Stamping.-A method for the production of a plain journal bearing comprising a backing of steel, a copper-lead or equivalent metallic interlayer bonded to the backing and an overlay of soft metal and wherein the interlayer is of varying thickness lengthwise of the bearing to form a surface which tapers off on a smooth curve to the ends of the bearing is characterized in that a blank consisting of a steel backing 1, having bonded thereto a layer 2 of uniform thickness of, e.g., copper-lead, is formed to semi-cylindrical shape by bending or pressing on a die, the formed blank being then positioned on a semi-cylindrical die cavity 3 and subjected to pressure exerted through a resilient tubular mandrel 5 of high tensile alloy interposed between the blank and a pressure applying member 6, the mandrel being substantially longer than the blank, e.g. 15 per cent to 40 per cent longer, so that when pressure is applied a greater pressure is exerted on the layer of copper-lead towards the ends of the blank than at the middle to form the desired shape of interlayer by plastic flow of the material. Subsequently an overlay 17 (Fig. 7) of soft metal, e.g. babbit, tin-lead, lead-indium, &c. is applied on the crowned copper-lead layer 2a by casting or by electro-deposition. The mandrel may be smaller in diameter at the middle than at the ends and accommodated in a parallel half bore in the pressure applying member by an intermediate layer of plastic material or soft metal, e.g. lead. The mandrel may be fitted with a solid core 7 (Fig. 3) shaped to provide an annular space 8 which may be charged with fluid, e.g. liquid at sub-zero temperature. The hydrostatic pressure within the mandrel may vary with the pressure applied by the member 6 by connecting the annular space 8 with a chamber 11 between two parts 6a, 6b of the pressure applying member 6. Pressure fluid from a pump 12 normally escapes from the chamber 11 between the joint faces of the parts 6a, 6b into a groove 13 from where it drains back to a supply tank 15. During the downward stroke of the member 6 fluid can only escape from the chamber 11 if the pressure becomes excessive and therefore the pump delivers pressure fluid to the annular space 8 for reinforcing the mandrel. In the final boring the overlay at the ends of the bearing may be from 0.0005 inch to 0.008 inch thicker than at the middle. The middle 18 of the overlay may be completely removed and the bore may be slightly' curved as shown by dotted lines 19 in Fig. 8, so that the ends of the bearing are, e.g., 0.001 inch less in wall thickness than the middle. Specification 685,319 is referred to.

Title: Method and apparatus for trimming stitches
IPC: D05B23/00
Filed: 1961-07-05
Abstract: 995, 274. Sewing machines; work-holders. A.B.TRONICS Inc. July 5, 1961 [Sept. 22, 1960], No.24255/61. Heading D1G. In a sewing machine a suction-exerting duct is so disposed as to draw the stitch chain between work pieces into means adapted to sever the chain. In arrangement Fig 3, for closing the transverse opening in the foot of a circularly-knit men's hose, needles 44 co-operate with an upper looper 46 and a lower looper, not shown. A fixed cutting blade 62 is disposed at an acute angle to the line of feed effected by a feed dog 50. A co-operating movable blade 64, pivoted at 86 to blade 62 and biased thereagainst by a spring 106, has a finger 102 embraced by the forked end of a bar 66 fixed at its other end to the feed bar 94 actuated by an eccentric 92 on a rotary shaft 90. A duct 68 has an open end disposed adjacent the blades 62, 64. A duct 70 discharges compressed air into duct 68 in a direction away from the open ends so as to create a suction at the latter. The work on leaving the stitching point is directed off the line of feed by an upwardly arched work guide and the stitch chain between successive workpieces is drawn between the blades 62, 64 by the suction at the open end of duct 68. The seam closing the longitudinal opening in the foot of a circularly-knitted women's hose is produced automatically by mounting a workpiece in a pivoted work holder comprising a pair of plates 132, 134, Fig. 6, hinged together at 136. Curved edges 138, 140 of said plates are concentric with a pivot pin 142 which depends from plate 132 into engagement with a fixed pivot post 144. The seam is thereby formed parallel to the edges 138, 140. Owing to the limited movement of the work holder, the thread chain at the completion of the seam will be directed away from the blades 62, 64, and more suction will therefore be needed to draw the thread chain therebetween at the end of the seam than at the beginning. The arrangement automatically provides the addition suction. An air pressure, line 154 is connected to a line 122, supplying duct 70, through a constricted passage 156 which by-passes a main passage 148, 152 normally closed by a magnetically-controlled valve 150. Towards the end of the seam, a cam projection 172 on plate 132 engages the actuating arm 170 of a micro switch 160 to effect the opening of valve 150.

Abstract: 855,395. Multifocal lens blank. PITTSBURGH PLATE GLASS CO. July 29, 1958 [Oct. 7, 1957(2)], No. 24380/58. Class 97(1) [Also in Group XXIII] A method of preparing a multifocal lens blank comprises fusing an optically finished minor segment assembly (comprising a minor segment of one glass and a carrier of the same glass as the major glass element) into a countersink of a major glass element, said assembly being formed by placing an optically finished surface of the carrier vertically under a stream of molten glass which fuses with the carrier to form the assembly on cooling. In a method described for forming the minor segment assembly (Fig. 3) the carrier, which may be formed from crown glass, is provided with an optically finished surface 14 and placed in a preheated mould 10 with surface 14 vertical, and molten glass (e.g. barium or flint glass) is poured in as shown in Fig. 4 (shears 17 being used to cut off the glass flow), and pressed down to fuse to said carrier. After cooling, the minor segment assembly 12, 13 thus formed is removed, one surface is optically ground, and the assembly is placed in a countersink 19 of the major lens blank 20 with said surface facing the blank (Fig. 8). The surface of the lens blank thus formed is then ground to the required shape. Alternatively the minor element carrier may be in the form of a button (Fig. 10) having a recess, bounded by walls 32, 33 which are sand blasted or etched to remove any dirt, and the surface 34 into which recess molten glass is poured, as before, to form the minor element assembly. The assembly is then ground and fused to the major blank, also as before, but when the final compound lens blank is ground the whole of the surface 34 of the button must be removed to expose the minor segment.
