Title: An improved apparatus for mounting and removing pneumatic tyre castings from and to vehicle wheels
IPC: B60C25/132
Filed: 1960-04-28
Abstract: 904,924. Mounting and removing tyre casings. MONTEVERDI, A. April 28, 1960 [April 29, 1959; July 18, 1959], No. 15035/60. Class 144 (1). A pneumatic tyre casing mounting and removal apparatus comprises a vertical central column 2 around which are disposed a plurality of vertically arranged hydraulic jacks 4 which act firstly, through removable blocks 13 bearing against a fixed flange a<SP>1</SP> of the wheel rim d and removable chocks 10<SP>1</SP> carried by a plate 9 and bearing against a removable flange a, to displace the flange a relative to the rim d to facilitate removal of a locking ring b and secondly by means of a ring 11 bearing against the tyre casing and chocks 10 carried by the plate 9 bearing against the wheel rim d to push the tyre casing from the rim d. The jacks 4 are adjustably mounted along the arms 3 to suit different diameter wheels. The hydraulic pump 5 feeding the jacks 4 may be operated manually or by electric motor. For removing tyre casings from small diameter wheels, Fig. 4 (not shown), the plate 9 is replaced by two members which are screwed on the central column to hold the wheel stationary and the tyre casings are removed by a known rotary arm device.

Title: Tire repair plug and method of use
IPC: B29C73/06
Filed: 1950-06-16
Abstract: 694,864. Pneumatic tyres. HAWKINSON CO., P. E. June 16, 1950 [April 26, 1950], No. 15154/50. Class 144 (i). A tyre repair plug comprises an inwardlytapering body-portion 2 of greater length than the thickness of the tyre, a flanged head 4, and a tapering tip-portion 7 by means of which the plug is drawn into the operative position shown in Fig. 4. In fitting the plug, the hole in the tyre is shaped, as by a reamer of the kind described in Specification 669,242, [Group XXII], to a size less than that of the plug-portion 2, so that when the latter is forcibly drawn into the hole the protruding part 1 expands to form an enlarged head bearing on the outer surface of the tyre. The major portion of the projecting part is then cut off. To facilitate assembly of the plug, the hole may be lubricated with liquid rubber cement. Specification 9737/15, [Class 144 (i)], also is referred to.

Title: Improvements in and relating to electric switches
IPC: H01H19/635
Filed: 1934-05-22
Abstract: 423,555. Heavy -current switches. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. May 22, 1934, Nos. 15273 and 15274. Convention dates, May 31, 1933. [Class 38 (v)] Contacts; switches, actuating pneumatic actuation; springs, arrangement of.- A switch has a pair of movable contact - carrying parts biassed apart by a spring and operating means for applying a force to either part to act through the resilience of the spring on the other part to close its contact against a cooperating contact. The contacts have surfaces which engage over a substantial area. As applied to a field - reversing switch of a traction motor, movable contacts 14, 15 cooperate with fixed contacts 16 .. 18, which have silver faces and are interconnected by a bar 82 which is welded or brazed to a bar 85 mounted by means of clamps 86 on a frame 60. Contact 14 comprises two silver contact faces 28, 29, welded or brazed to copper blocks 25, 26 which are clamped to seals 32, for springs 34 with intervening tubes 20, which are cold forged over braid 22. The braid 22 is welded to terminal 23 which is clamped at 44, 45 to the frame 60 by means of screws 66, 67. The intermediate contact 17 has silver faces 74, 75 co-operating with, respectively, 29 and a face 52 on contact 15 which contact is similar in construction to 14. Contact 17 has a terminal 72, and is clamped to 60 by clamps 78, insulation 92 separating the several clamps. The contacts 28, 29, &c. are urged apart by springs 34 and the seats 32 have projecting parts 41 on each side engaging in a window 40 in an operating arm 38. The arms of both contacts 14, 15 are riveted at 96 to an insulating cradle 95 which is guided by slots and rollers 103, 107. For reciprocating the cradle, a vertical slot 112 is engaged by a roller 110 on a cam 113 which is rotated through a rack and pinion by the piston 120 of an air engine. In the position shown in Fig. 3, where 110 is below the centre of slot 112, the contacts 14, 16 and 15, 17 are in engagement, and the spring pressure is arranged not only to produce the contact pressure, but also to act back through the drive to hold piston 120 at its lower position, whereby no air pressure is required to maintain the contacts in position. To reverse the contacts, air is admitted to raise the piston and move 110 up to the centre line of 112, so further compressing the contact springs. Further movement moves 95 to the right, relaxing the springs until 14, 15 engage 17, 18, when they are again compressed. When the roller 110 again moves below the centre of 112, the springs relax slightly and serve to maintain piston 120 at its upper position independently of the air supply. The cradle also carries contacts 146 co-operating with further contacts for the interlock circuits of the magnet valves of the air supply.

Abstract: 952,695. Wells. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. April 19, 1962 [April 24, 1961], No. 15296/62. Heading E1F. Apparatus to be connected to an underwater wellhead 39 comprises a housing 45, a chamber 46 in the housing, a piston 47 in the chamber, batches 49 mounted on the housing and movable by the piston to engage the wellhead, conduits 43, 44 connected to pumps 57, 58 to supply fluid to the chamber to move the pistons, and a central valve 73 moved by an actuator 77 so that fluid from the pump 57 moves the piston downwardly to engage the latches and fluid from the pump 58 moves the piston upwardly to free the latches. A reversible electric motor 55 controlled from a switch box 38 drives the pumps through clutches 59, 60, the arrangement being that rotation of the motor in one direction drives one pump and rotation in the other direction drives the other pump. The outlets of the pumps are connected to the controller, and to the valve, non return valves 75, 76 being included in the conduits. With the pump 57 operating the valve and controller are set as shown so that fluid flows through the conduit 43 to engage the latches, and with the pump 58 operating the controller sets the valve so that fluid flows through the conduit 44 to free the latches. In a modification the apparatus is adapted to fit, and the latches to engage the interior of a well head. The apparatus may attach a blow-out preventer to a well head, and further apparatus may connect a marine conductor to the preventer. Specifications 924,904 and 948,322 are referred to.

In alternative embodiments the button is replaced by a metal ball (Fig. 2, not shown), a leaf spring (Fig. 3, not shown), a staple (Fig. 4, not shown) or a rivet (Fig. 5, not shown). In Fig. 6 (not shown) lugs on the bottom plate extend through the plastics layer and engage the cup-shaped electrode. In Fig. 7 (not shown) the cup-shaped electrode is enclosed in a plastics jacket having an integrally formed bottom which corresponds to the plastics layer, and a metal plate secured to the bottom of the jacket makes contact with the cup-shaped electrode in any of the ways described above e.g. by a metal ball embedded in the bottom of the plastics jacket.

Abstract: 401,386. Lifting-jacks. VENNER, D. J. V., Eversure Works, Kingston Road, Small Heath, Birmingham. June 1, 1932, No. 15496. [Class 78 (iii).] An hydraulic jack of the doublelift type with two concentric rams is provided with two pump plungers 10, 11 of different diameters, the larger being used for the first stage of the lift and the smaller for the second stage. The plungers are side by side and are operated by the same lever which is pivoted on a spindle 13 and is movable laterally to bring its short arm 22 into engagement with a recess 12 in either plunger. This movement is effected by turning the handle on its own axis within the sleeve part 95 so that a toothed part 16 engages with rack teeth on the spindle 13 and moves the handle bodily to right or left. A pin 18 in the handle snaps into a notch 29 in the sleeve part 15 when the handle is in the central position and disengaged from both plungers, and the handle is then in position to engage a rod 24 for opening a valve 25 for lowering.
