Filed: 1964-09-07
Abstract: 1,083,354. Making pipe fittings. AGENCY OF INDUSTRIAL SCIENCE & TECHNOLOGY. Sept. 7, 1964 [Dec. 21, 1963 (2)], No. 36545/64. Headings B3A and B3Q. Apparatus for forming branched tubular members in a split die by liquid pressure comprises piston rods 4, 4<SP>1</SP> movable by pistons 8, 8<SP>1</SP> against the ends of the members 1 to be formed, and means for synchronizing movements of the piston rods. After closing the die by an hydraulic ram 3, liquid is supplied to the interior of the workpiece, through a bore in the piston and rod 8, 4 by a pump 7, air being expelled through the other piston and rod 81, 4<SP>1</SP> until a check-valve 16 closes. A further pump 6 supplies cylinders 5, 5<SP>1</SP>, 18, 18<SP>1</SP> for pressing the rods 4, 4<SP>1</SP> against the ends of the workpiece, and another pump 21, through a compressor 11, supplies the pressure for expanding the workpiece. To compensate for outward pressure on the end of the piston rods 4, 4<SP>1</SP>, the pump 21 is also connected, through a balancing cylinder 17, to the larger cylinders 18, 181. A cam 27 on the piston rod 4 operates a regulator valve 19 controlling the main pump 21. A plunger 31, backed by a piston 24, produces a flat end on the branch, the plunger also serving to eject the finished work. Movements of the piston rods 4, 4<SP>1</SP> are synchronized by a pinion 14 meshing with racks 13, 13<SP>1</SP> on the piston rods. The ends of the piston rods may be conical or formed with edges (Fig. 3). In a further form, Figs. 7 and 9, for producing a multi-branch tube (Fig. 10), the die is additionally clamped by end plates 35, 35<SP>1</SP> which engage over the tapered ends of the die. Plungers (51, 511, Fig. 8) in the two larger-diameter branches of the die are controlled by a cam 54, Fig. 7, driven, through a rack-and-pinion 52, 53, by the synchronizing pinion 41. Outward pressure on the pistons rods 42, 42<SP>1</SP> is balanced by inward pressure on the ends of stems 50, 50<SP>1</SP> bearing on the pistons 38, 38<SP>1</SP>. Openings (Fig. 11b) are formed in the ends of the two smaller-diameter branches by punches 57, 57<SP>1</SP> while the interior of the workpiece is supported by the liquid under pressure. Withdrawal of the pistons 38, 38<SP>1</SP> causes ejection of the workpiece by the plungers (51, 51<SP>1</SP>).

Title: Furniture wheels
IPC: B60B33/02
Filed: 1976-09-03
Abstract: 1531795 Castor wheels HUFA-ROLLEN HUGO FASSBENDER KG 3 Sept 1976 [5 Sept 1975 6 March 1976 25 Aug 1976] 36569/76 Heading A4U [Also in Division F2] A furniture wheel combination, e.g. a castor wheel in a housing for an office chair, comprises a wheel having a hub through which is a bore, and an axle lying in the bore with clearance, the axle, or a spring or the like interposed between the axle and the bore, exerting resistance to rotation of the wheel around the axle, such resistance being sufficient to maintain the chair at rest when unoccupied; increased load on the wheel via the axle (e.g. on occupation of the chair) causes reduction in the resistance to rotation exerted by the axle or the spring or the like, to permit movement of the chair. In the first form an axle 5, Fig. 2, is held at both ends against rotation in the side walls 2' of the housing (2) forming part of a furniture castor (1) Fig. 1 (not shown). The axle 5 is a loose fit in a bore of the hub 6 of the castor wheel (3) and has a longitudinal slot 8 located in its underside. A spring 9, whose central portion consists of a downwardly-curved crest S, is located in slot 8 with its crest S in contact with the adjacent part of the hub bore and its ends in contact with the base of slot 8. In the position of Fig. 2 with the furniture (e.g. an office chair) unoccupied (unloaded), spring 9 raises housing (2) and the axle so that the axle makes contact at the top with the upper part of the bore in the hub, thus braking the wheel (3). In the Fig. 3 position, the chair being occupied, the spring 9 is compressed, so axle 5 is clear of the upper part of the hub bore, and the wheel may be rotated by movement of the chair by the occupant. There are minor variants. In the second form, in the clearance between axle 36, Fig. 10, and hub bore 39, a longitudinallysplit resilient braking sleeve 37 is accommodated, and is pre-stressed so that in the "unloaded" position the sleeve contacts three-quarters of the hub bore surface, while in the "loaded" position, Fig. 11, it contacts only about one quarter of the surface. In the third form the axle 56, Fig. 13, is resilient and is pre-stressed into a curved configuration, so that in the "unloaded" position the axle middle contacts the middle lower surface of the bore, and the axle ends contact the end upper surfaces of the bore. In the "loaded" position the axle is straightened out, Fig. 14, making minimal contact with the bore and thus offering minimal resistance to movement. In Figs. 17-20 (not shown), the ends of the axle are split and portions are pre-stressed curved.

Abstract: 1397775 Valves BLACK & DECKER MFG CO 8 Aug 1972 [16 Aug 1971] 36896/72 Heading G3B [Also in Divisions Fl and F2] A cut-off device for a rotary fluid-pressureoperated machine such as an air-operated grinder comprises a valve 23, Fig.2, for controlling the delivery of pressurized fluid from an inlet 37 to an outlet 39 leading to a vane-type motor 17, a spring 83 for moving the valve into its closed position, latch means for isolating the spring and control means for effecting disengagement of the latch only when the speed of rotation of the machine exceeds a predetermined value. The latch comprises a trigger 77 extending from a rotatable holder 59. The holder is restrained from axial movement, under the action of spring 83, by arcuate projections 64 on a stationary housing 61 underlying similar projections on the holder. The control means, in one example, comprises a pair of pivoted weights 87 and 89, Fig.5, which rotate with the machine and move outwardly under centrifugal force to strike the trigger 77. The holder 59 is thereby rotated, whereupon it is freed for axial movement and snaps the valve into its closed position. The speed at which the weights strike the trigger is pre-set by a screw 98. In other examples, the control means comprises a single pivoted weight (89'), Fig.10 (not shown), or a radially slidable weight (101), Fig.9 (not shown). In the normal course of events, the speed of the motor is automatically regulated by a pair of fly-weights 71, Fig.2, which act on a lever 63 to adjust the position of the valve with respect to its seat 35. If this mechanism fails, and the speed of the motor rises, the cut-off device comes into operation.
