Title: Vehicle disc braking assembly
IPC: F16D65/14
Filed: 1971-05-26
Abstract: 1318814 Disc brakes KELSEY-HAYES CO 26 May 1971 [1 June 1970] 17280/71 Heading F2E In a brake assembly having two actuators for a brake shoe or pad a self energizing force is exerted upon the pad only when operated by one of the actuators. In the embodiment shown is a floating caliper 15, disc brake 11, having a fluid pressure actuator comprising a piston 18 which causes engagement of a brake pad 22 with a disc 12 through a plate 39 and a backing plate 24 between which plates is located a roller 33 engaging embossments 31, 32 on backing plate 24 and embossment 38 on plate 39. Two pins 55, 56 extend through key-shaped slots 71, 72 in backing plate 24, apertures 66, 67 in plate 39 caliper bores 57, 58, and apertures 53, 54 in an actuating member 51. Pairs of levers 45, 46, journalled on a pin 44, have cam surfaces 47, 48 engaging member 51, and are actuated to effect a parking application through operating levers 76, 77 pivoted thereto, themselves pivoted by means of a pin 82 to a trunnion 81 connected to a wire 83. When a tensile force is exerted on wire 83 levers 45, 46 pivot about pin 45 causing cam surfaces 47, 48 to exert a force on member 51 which is transmitted via spring biased canted washers 62, 63, pins 55, 56 to pad 22. Backing plate 24 tends to move slightly away from plate 39 and rotates relative thereto due to the slots 71, 72 so that roller 35 is displaced and is loaded between surfaces 34 and 36 or 33 and 37 on the embossments 31, 32, 38 thereby holding plate 24 against further rotation. The axial component of the force resisting this movement effects a servo action on pad 22. When the linings 23, 28 of the brake pads is sufficiently worn the excess slack is taken up during a parking application by washers 62, 63 which shift away from member 51 against the bias of springs 59, 61. To provide a backing for plate 39 a canted washer (85), Fig. 4 (not shown) is interposed between piston 18 and a groove (86) in caliper 17 to permit free movement of piston 18. Excess movement upon retraction of piston 18 is resisted by the cant of washer 85 engaging caliper groove (86).

Abstract: 982,839. Lever jacks; removable load containers for vahicles. SHEPHERD WOODWORK Ltd. May 10, 1962 [May 11, 1961], No. 17303/61. Headings B8E and B8J. A load support comprises a telescopic leg having an inner member 1 and an outer member 2 to which brackets 6, 10 for connection to the load are welded and which is supported on a pin 14 passing through one of a series of holes 13 in the member 1. A lever 17, for raising the member 2 comprises a pair of side plates 20, shaped as shown, provided with lugs 24 adapted to engage over a fulcrum pin 24 mounted in one of the holes 13 and a socket for receiving an operating handle 18. In operation, with the member 2 supported by pin 14, the pin 16 is positioned to support the lever 17 so that the plates 20 engage the bottom of the bracket 10. Then, on downward movement of the handle 18, the plates 20 raise the member 2 sufficiently to allow the pin 14 to de raised to the next hole 13 whereupon the member 2 is allowed to descend on to the pin 14. The pin 16 is then raised and the cycle is repeated. 'The member 2 may be raised through half the distance between the holes 13 and locked to the member 1 by passing the pin 14 through a hole 26 in the member 2 and one of the holes 13. A spigot 5, having an external diameter less than the internal diameter of the member 1, is secured in an opening in the closure plate 4 on the member 2 so that it may be fitted into the bottom of the inner member ofanother similar support. A plurality of supports may be attached to a structure carried by a lorry so that, to unload the structure, the inner members are lowered to the ground, the structure is raised slightly above the lorry platform and the lorry is driven away.

Title: Improvements in or relating to the manufacture of oil-filled electric cables
Inventor: TOBIA VINCENT
IPC: H01B13/30
Filed: 1965-04-26
Abstract: 1,104,176. Oil-filled cables. PIRELLI GENERAL CABLE WORKS Ltd. 25 March, 1966 [26 April, 1965], No. 17479/65. Heading H1A. In the manufacture of oil-filled cables by mass-impregnation or post-impregnation the cable core is passed in turn through a cabledrying or combined cable-drying and impregnating tank and then through a cable-sheathing means, though these steps are not continuous. To improve the efficiency of this process the present invention provides, as shown, a set of fixed sheathing means 1, 2, 2 and a set of tanks 7, 7a mounted on tank frames 6, 6a which are movable in two directions along rails between positions adjacent and remote from the sheathing means. During the sheathing process the tanks are mounted in a pit 4 on parallel front tracks 5 adjacent the sheathing means. When the tank has discharged its length of cable core to the sheathing means the tank mouth 8 is disconnected from the tube 9 and the tank on its frame is moved backwards on the tracks 5 on to the tracks 14 of a bogie 13 which itself is movable along tracks 12 fixed at right-angles to the front tracks 5. The bogie is moved sideways until its tracks 14 coincide with a vacant set of rear tracks 10 on to which the tank is moved and where the tank is reloaded with cable which is then dried and possibly impregnated. A loaded tank on the tracks 10 in which the desired environment has already been created is then moved forward on to the bogie and transported to a vacant front track 5 where it may be connected to a free-sheathing means. As shown, a free set of tracks is left in both the front and rear rows of tracks to simplify the tank movements. The tanks may be powered by motors fixed to the frames and their movements may be controlled by limit switches. Loading means 15 and environment producing means 16 are provided behind the tracks 10 and associated with each sheathing means, which may be of different types, for example lead or aluminium, is a cable drum winding station 3. Depending on the length of time required for each step it may be more efficient to keep the tanks fixed and have the sheathing means movable in a manner similar to the movable tanks described above.

Title: Improvements in electric reversing switches
IPC: H01H21/60
Filed: 1943-10-25
Abstract: 566,648. Snap-action switches. CHICAGO PNEUMATIC TOOL CO. Oct. 25, 1943, No. 17534. Convention date, Feb. 15, 1943. [Classes 38 (iii) and 38 (v)] A reversing switch has an operating handle normally in a neutral position and two sets of contacts, brought into engagement if the handle is moved in either direction; movement on one side, however, first alters the initial relation of the sets of contacts to reverse the connections effected by the switch, and then moves the sets into engagement for closing the circuit in reverse direction. As shown, a handle 16 detachably mounted in a sleeve 55 can take up a position on each side of normal by registration of a spring plunger 59 in one of the depressions 61 oh a disc 58 secured to sleeve 55. The sleeve has secured to it a cam 62 formed with a slot 66 and a projection 63 acting as pivot for an operating arm 64. The sets of contacts are both movable, one set 21, 22, 23, 24 mounted on a block 19 is slidable laterally, and the other set comprising spring tongues 26, moved against the first set in one or other of the extreme positions taken up by the first when slidden in one direction or the other. From the neutral position of the handle in which the cam 62 is in the position shown in Fig. 10, if the shaft 55 is rotated clockwise, a pin 65 and roller in slot 66 is unaffected while the arm .64 is raised to swing up a bail 37 attached at its ends by arms 35, 36 to a shaft 33 bearing the spring contact tongues 26 to cause them to engage with contacts 21, 23 and 24 to close a circuit through a motor in a given direction. A snap-action is achieved through dead-centre spring toggles 35a, 39 and a link 41 moving between limit brackets 45. If the handle 16 is moved back to neutral, the contacts 26 snap off, and movement to the other side of neutral moves the shaft 55 and cam 62 anti-clockwise. The cam 62, during the first part of its motion slides the pin 65 outwards in part 69 of slot 66. This moves the block 19 holding contacts 21 ... 24 to the right to bring the left-hand end of contact 21 and contacts 22 and 23 opposite the spring blades 26. During this part of the motion of the cam, the arm 64 swings across with lost motion and only when the cam rotates further does the arm 64 lift to the position of Fig. 13, effecting the snap closure of contacts 26 to engage contacts 21, 22, 23, making a circuit through the motor in a reverse direction. Access to the mechanism can only be obtained by removing a screw disc 73 after a locking element 76 is moved to clear an aperture in a hood 77 by moving handle 16 to neutral, and then removing handle 16 and shaft 53 by undoing bolt 56. The enclosure is dust- and water-proof. Specification 341,763 is referred to.

Filed: 1928-06-20
Abstract: 319,395. Stricker, P. June 20, 1928. Interlocking and guarding against wrong movement.-A truck driven by an internal-combustion engine is provided with a pedal lever which, when it is depressed, as is normally the case, leaves the reversing gear free to be set for either direction and when released locks the reversing gear in the neutral position. In the construction shown in plan in Fig. 5, the bevel reversing gear of the truck is controlled by a hand lever 23 through a lever 21, arm 24 and a sliding clutch member (not shown); the lever 21 also reciprocates a cam plate 32 in fixed guide 38. A pedal 35 is connected by a rod 34 to spring 37 and a lug 33 on the rod engages in a cam slot shaped as shown in the plate 32, so that when the pedal 35 is depressed the rod 34 is moved to the left or forwardly, and the lug 33 moves into the wide part of the slot leaving the cam plate, and therefore the reversing gear, free to be operated. A spring 43 is connected through the plate 42 and a lever 39 to the brake, a pin on the plate 42 engaging in a slot in the plate 36. When the pedal is released the spring 43 applies the brake and the lug 33 acts on a sloping face of the slot to move the cam plate until the reversing gear is in the neutral position where it is locked by the narrow part of the slot. The engine 4, Fig. 1, is mounted at one side of the driver's platform 3 and drives the front axle or a countershaft through change-speed gearing 5 and bevel reversing gear on the countershaft. A steering handle 10 and a change-speed lever 9 are provided.

Title: Improvements in hydraulically-actuated reversing mechanism
IPC: F16H61/02
Filed: 1930-06-12
Abstract: 359,446. Reciprocating-pumps. AMERICAN ENGINEERING CO., Ara. mingo Avenue, Philadelphia, U.S.A. June 12, 1930, No. 18063. Convention date, Sept. 10, 1929. [Class 102 (i).] Means for periodically and automatically reversing a hydraulically-actuated piston comprises a hydraulically-actuated valve which is held in its end positions by a spring-actuated detent until the operating liquid has reached a pressure sufficient to release the detent; a similar detent is applied to the piston, and the form described is one in which the piston operates the output-reversing mechanism of pumps used for supplying liquid to operate hydraulic stoking mechanism. The stoking mechan. ism comprises pumps 3, 4, Fig. 13, connected by pipes 7, 8 to the cylinders 9 of hydraulic rams, and supplementary pump ports are connected to ports 51, 52, Figs. 5 and 6, so that when the pump flow is reversed, a valve 34 is moved from one end position to the other, when the pressure has reached a value sufficient to depress the detent 62 against the action of a spring 65 ; the pressure reaches the detent by throwing over a shuttle valve 59, and passing through a passage 59<1>, Fig. 7. The pipes 7, 8 are connected through non-return valves to a pipe 73 so that there is always pressure in the latter, and the valve 34 controls communication between the pipe 73 and the opposite ends of a cylinder 35 containing a piston 36. In order to keep the pressure in the pipe 73 constant and allow escape therefrom if it exceeds a predetermined value, it is connected to a cylinder 96, Fig. 9, having a piston loaded by springs 107, and escape openings 97, 98. The piston 36 oscillates a shaft 21, which is also connected to a block 79 locked in its end positions by a detent 84, which is freed similarly to the detent 62. The shaft 21 reciprocates a block 18, Fig. 11, between nuts 15, 16 on the pump control rod 11 to reverse the pump output, the quantity of output being varied by adjusting the distance between the nuts by means of a handwheel 23 geared to an indicator. Exhaust liquid from the cylinder 35 passes through a pipe to a reservoir the pipes 7, 8 being also connected to the reservoir through replenishing valves.

[Class 56] Relates to a method of making vasa diatreta wherein a glass vessel 3 is enclosed in an outer shell 2, preferably with apertures 13, to form a network, which is connected to the vessel 3 solely by glass bars 10. A doublewalled vessel is made first in the known manner by blowing a hollow body, adding more glass, reheating, and then working the glass inwards by a tool 5, Fig. 5, to form the walls 2, 3 separated by a space 6. While the body thus formed is still in the pipe and the glass is still plastic, the outer wall 2 is heated locally, for example, by applying small blobs of hot glass 7, Fig. 8, and a glass rod 8 is forced through the softened glass until it makes contact with, and adheres to, the wall 3. The projecting part of the rod 8 is then broken away leaving a projecting blob of glass on the wall 2 while a glass bar extends between the two walls. After the required number of bars have been inserted, the excess glass is ground away and apertures 13, Fig. 13, are formed in the wall 2 by any suitable means.
