Title: Improvements in or relating to chucks for machine-tools
IPC: B23B31/18
Filed: 1957-02-22
Abstract: 824,016. Chucks. ERNAULT-BATIGNOLLES S.A., H. Feb. 22, 1957 [Feb. 28, 1956], No. 6093/57. Class 83 (3). A chuck has at least three adjustable-dogs for supporting and centring a workpiece prior to being gripped by jaws, the dogs resisting displacement by the workpiece. The jaws 36-38, Fig. 4, are guided radially at 59<SP>1</SP>, 61 in the body 1, and are actuated by bell-crank levers 62, pivoted at 63. The levers 62 engage a housing 67 in a ball-joint 53, having spherical surfaces 68 engaging similar surfaces on an axially-slidable bush 54, thus giving a self-centring action to the jaws 36-38. The dogs 42, 57, 58, pivoted at 41, are normally spring-urged by studs 47 in the body to engage the work 5, and are moved in an opposite direction by sliding-pins 51. In operation, the bush 54 is moved to the right, Fig. 4, so as to open the jaws 36 &c. and engage the pins 51, thereby opening the dogs 42 &c. After inserting work 5 in the bore of the chuck, bush 54 is moved to the left to allow pins 47 to engage dogs 42 &c. lightly with the work, to lock it centrally with respect to supporting-centres 31, and then to close jaws 36 on the work to grip it. In a modification, the jaws 2, Figs. 6 and 7, are formed as pistons sliding radially in cylinders 7 in the chuck body, and are normally pressed outwardly by springs 4. The centring-dogs 8 are urged radially inwards by wedges 3, pressed in the closing direction by light springs 9 and in the opening direction by fluid-pressure acting on their ends 3<SP>1</SP>. The wedges and dogs are also maintained in contact by spring pins 11. In operation, pressure-fluid is supplied by a hand-controlled valve to wedges 3 to release dogs 8 and allow work 5 to be inserted and centred by centres 31. The valve is then actuated to cut-off fluid from the wedges, allowing springs 9 to engage dogs 8 with the work to lock it centrally, after which fluid is admitted by the valve to cylinders 7 to cause jaws 2 to grip the work. A chuck may have two axially-spaced sets of jaws 2 and dogs 8 so that the centres 31 may be released after the jaws have gripped the work, to allow machining of the work ends. Mounting.-The chuck may be mounted in roller-bearings 22, 23, Fig. 7, and driven by a central-gear 26 and pinion 28.

Abstract: 1,083,895. Coating conductors by extrusion. STANDARD TELEPHONES & CABLES Ltd. Feb. 12, 1965 [Feb. 13, 1964], No. 6097/64. Heading B5A. In a method of coating an electrical conductor with insulating material the coated conductor is passed through a compression chamber 13-17 curved in conformity with the natural sag of the cable, attached directly to extrusion nozzle 7 and provided with a compressed air inlet 38 to maintain an air water interface 41 away from the nozzle. A liquid outlet 40 and bleed passage 39 are interconnected by means of a valve and pressure sensitive element (neither shown), to keep the position of interface 41 substantially constant. Generally a hawser (1), Fig. 1 (not shown), from reel (2) is heated by electrode wheels (11, 12) before and after passing through a drying chamber (3), the hawser is clad in copper strip (4), welded or box seamed in position at (6), thermoplastics insulating material such as polyethylene is extruded around the copper clad hawser at (7) and the electrical cable thereby formed is passed through a compression chamber (8), a modified form to that shown in Fig. 3, the pressure being applied to the cable by liquid at a value sufficient to prevent cavity formation in the insulant. The compression chamber (8) is fed with hot water under pressure from a tank (23) by a pump (24) and returned to the tank by pumps (34, 35). The pressure within the chamber is regulated by the provision of baffles (28) and (31), Fig. 2 (not shown), or a bleed pipe (not shown) between the baffles, the water being strained by gauzes (29, 32). Although hot water is used in chamber (8), its temperature is less than that of the insulant immediately after the latter leaves the extrusion die. More than one chamber (8) may be utilized. Drying chamber (3), Fig. 1 (not shown), is connected to a pump (10) and is kept below atmospheric pressure, liquid in the hawser interstices being vaporized therein as a result of heating by electrode wheels (11, 12). The insulant may surround a corrugated metal sheath rather than a hawser.
