Title: Improvements in or relating to securing friction linings for brakes or clutches
IPC: F16D69/00
Filed: 1954-11-09
Abstract: 768,856. Brake linings. DEMAG-ZAG GES. Nov. 9, 1954 [Nov. 14, 1953], No. 32444/54. Class 103 (1). [Also in Group XXIV] In a friction lining for brakes or clutches, the friction lining, instead of being riveted or bonded to the support member, is connected to its support member by an elastic intermediate layer which bears on its support with initial tension, the material of the intermediate layer having a higher co-efficient of friction than the material used as the friction lining. The initial tension of the intermediate layer required for this purpose is achieved by providing the inner diameter slightly smaller than the outer diameter of the support and by providing the outer diameter of the intermediate layer slightly larger than the inner diameter of the friction lining. Figs. 1-3 illustrate a number of examples applied to a cone brake or clutch, the disc 1 supporting the elastic intermediate layer 2 which is pressed on to the disc and a friction lining 3 which is pressed on to the intermediate layer. Specification 725,588 is referred to.

Title: Improvements in methods of cold extrusion of metals

Abstract: 897,015. Extruding. SOC. F. MARTI & FILS. Sept. 28, 1959 [Oct. 6, 1958; Dec. 11, 1958], No. 32852/59, Class 83 (4). A method of coldextruding a metal workpiece, particularly of alloy steel, comprises forming a depression 6 in the top of the workpiece la, Fig. 2, depositing a solid lubricant in the depression, and then piercing completely through the workpiece and separating therefrom the web of material 6 driven forwardly by the piercing punch 4. A cylindrical, oval or polygonal section blank provided with a phosphate coating, is placed in a die 2, 3 and indented by the punch 4. The indent 6 is filled with a solid lubricant, particularly molybdenum or tungsten bisulphide, and is pierced partially through with backward extrusion, Fig. 3 (not shown). An ejecter 5 actuated by a member 5a is provided. Die 2 is then placed upon another bottom die 3a, Fig. 4, and the punch 4 is forced completely through the workpiece to sever off a wad 6 at the throat 10. After removing any burrs by reaming, followed possibly by a preliminary heat treatment for several hours at 300-400‹ C. and then immersing in the solid lubricant, the workpiece le is inserted, in a reversed position, in an extrusion die 17, Fig. 6, another workpiece 1d is placed on top to act as a block, and the workpiece le is cold extruded by a ram 12 carrying a mandrel 13 to form a tube 1# which may be used subsequently as a gudgeon-pin. An undercut groove 18 prevents the workpiece being raised with the mandrel. In a modification, Fig. 10, the ram 10 is recessed at 22 to form an annular groove 19 in the workpiece for receiving the solid lubricant. The latter may be suspended in a lubricating soap. A press having a revolving work-table may be used for performing the various steps.

In a pipe-laying tractor-mounted boom including two spaced upstanding legs 11, means are provided to tilt the boom for improving distribution of weight supported thereby when the vehicle is disposed on an incline and comprises pivotal connections between the lower ends of the legs and the vehicle, a link 16 extending between and pivoted to the legs adjacent the upper ends thereof, and a poweractuated, extensible member between the link and one of the legs. As shown, the legs are secured to one side of a tractor 10 by universal hinge connections 13 so as to permit the top of the boom to swing longitudinally and outwardly to one side of the tractor, the link 16 having extension 18 to which are pivotally connected hydraulic jacks 19. The link 16 supports blocks 21, 22 through which a cable 23 passes to provide a fall which supports a cradle 24 provided with anti-friction rollers 26; the cable passes through a fairlead 25 to a winch.

Title: Hydraulic tracer-control-unit for machine tools
IPC: B23Q35/36
Filed: 1958-10-16
Abstract: 844,135. Copy-milling. CINCINNATI MILLING MACHINE CO. Oct. 16, 1958 [Oct. 21, 1957], No. 33027/58. Class 83 (3). A tracer-assembly comprises tracer-operated valve members 23 radially spaced about, and movable axially parallel to, the tracer 13. Movement of the axis of the hand-guided tracer 13 in a vertical plane parallel to the movement of the controlled slide in one direction, tilts a disc 22 about a spherical-seat 55 to operate a valve 18. A similar valve is operated similarly when the tracer axis moves in a vertical plane perpendicular to the former plane. Axial movement of the tracer, on balls 72, corresponding to vertical movement of the slide, operates a valve 20. The bushing 24 of each valve controlled by the plate 22 is urged downwardly by a spring against an adjustable stop. The plate 22 is connected to each valve 23 by a spring-pressed plunger 48 and a ball 50. The degree of lateral deflection permitted is controlled by rotation of a collar 61, to determine the clearance between a conical surface 62 and a sleeve 63. The sleeve 63 can be moved upwardly by a knob carrying an eccentric-pin engaging a groove 64 in the sleeve, thus allowing rapid movement of the slides, while moving the tracer 13 upwardly by means of a rod 94 to raise it from the pattern. The degree of vertical movement permitted to the tracer is determined by a collar 74. The valve 79 is urged downwardly by a spring 80 against a seat 78 on the tracer, the seats 78, 55, having a centre-of-curvature 97 lying in the plane of the top of the plate 22. To produce an automatic feed of the work, a collar 106 at the top of the unit is rotated to position a spring-pressed rod 111, which is released to bear against the tracer and bias it in the feed-direction desired. The feed continues at the speed determined by the setting of the collar 61. To enable the operator to guide the tracer in a recessed pattern, a control knob is secured on the upper end of the tracer by a threaded aperture 135.
