Filed: 1919-11-28
Abstract: 158,436. Zweigbergk, T. Nov. 28, 1919. Motors, supporting; electric tramcars, railway motor cars, and locomotives.-In an electric traction motor drive embodying an idler wheel between the motor pinion and the driven shaft, the motor end plate, which contains the motor shaft bearing, has an extension forming a bracket carrying the idler so that the motor with its pinion and the idler form a complete unit. In the form shown, the motor has the usual bearing in the running axle D, which it drives at each end from a pinion T through ar. idler S gearing with a spur-wheel U outside the road wheel. The motor end plate has a flat circular seating F from which projects a tubular part G including the motor shaft bearing H and cut away at one side to clear the road wheel. An outer flat part J of the part G carries a forked bracket K formed bv inner and outer circular plates N, P connected by a cylindrical wall. The plate N is formed as an eccentric thickened part of the end plate extension J and the two plates N, P are bored to receive the spindle Q of the idler S, the spindle being held against rotation by a key R sunk in its end and in the plate P. The plate P is cut away at its lower end so that the pinion T may be put on the motor shaft when this is in place. The split gear-case E is supported by a groove 0 turned in the plate N and by a bracket V projecting from the motor end plate.

A chisel for splitting slates comprises a first member 1 which has a cutting edge 4 defined by two mutually inclined faces 5, 6 and is slidable within a second member 3 having two inclined faces 7, 8 which in a first relative position of the members form respective continuations of the faces 5, 6 to form a composite chisel blade, and means for advancing the first member relative to the second. The inclined faces subtend an angle of not less than 30 degrees and not more than 135 degrees and preferably 90 degrees. The first member is slidable in a slot in the second member and, in operation, with the first member  retracted in the slot, an hydraulic ram 9 moves the chisel into engagement with a piece of slate to be split until the split portions of the slate engage the inclined faces 7, 8 of the second member. Thereafter, hydraulic rams 2 advance the first member 1 at a predetermined speed into the split. In another embodiment, the crosssection of the first member has an arrowheaded cross-section.

Abstract: 1,244,658. Valves. CLEAR HOOTERS Ltd. 17 June, 1969 [22 June, 1968], No. 29878/68. Heading F2V. [Also in Division G3] The valve is for regulating the degree of vacuum applied to a servomotor, e.g. on a vehicle, through a connection 16, 17 from a source connected at 22, 23 to a chamber 15. The valve comprises a body 13, e.g. a plastic moulding having the chamber 15 closed by a pressure responsive diaphragm 24. A valve member carries a first obturator 32 controlling communication between chamber 15 and the source, and a second obturator 29 controlling communication between chamber 15 and atmosphere through a seat opening in the diaphragm. This diaphragm has a boss 35 with a flange 34 beneath which is a rigid washer 48 and beneath the washer a blade spring 36. The washer is engaged with the spring in a manner permitting limited rocking movement. Two tabs 49 on the washer engage in holes in the spring so as to space them apart and permit the rocking movement. The spring is anchored at 39 and adjustable from the other end through an adjustable tappet 41 engaged by a cam 42 which is rotatable by a stem 43. Rotation of the cam in both directions is limited by a stop (45) engaging a lug (46), Fig. 3 (not shown). In one extreme position the diaphragm is lowered to isolate the source and open the chamber 15 to atmosphere. In other positions the valve modulates the degree of vacuum in the chamber automatically.

Title: An hydraulic master cylinder and dual piston assembly
Inventor: PAGE ERNEST
IPC: B60T11/20
Filed: 1960-08-31
Abstract: 887,631. Hydraulic master cylinders. FORD MOTOR CO. Ltd. Aug. 31, 1960, No. 30054/60. Class 103 (1). In an hydraulic master cylinder and dual piston assembly, particularly for " tandem " or dual system master cylinders used in the hydraulic braking systems for controlling two separate hydraulic circuits, a primary piston 14a creates a pressure in space 15 to actuate a secondary piston 12 which secondary piston operates simultaneously spring-loaded tiltable check valves 4 and 5 controlling communication between the cylinder and hydraulic reservoir in each hydraulic circuit. A spring 19 normally separates primary and secondary pistons and, if the primary chamber 15 should suffer a pressure loss due to a broken pipe, the spring 19 permits abutment of primary and secondary pistons when pressure is applied on the brake pedal. By this means pressure may still be exerted on the secondary circuit through outlet connection 6. Should there be a pressure loss in the secondary chamber 18 due to pipe breakage, the secondary piston 12 will travel into abutment with the end 8 of the secondary chamber and permit pressure build-up in primary chamber 15 to continue to supply pressure fluid to the primary circuit through outlet connection 7.

The screw 29 is thereafter screwed upwardly so as to clamp together the reflector and the fitting. The keyhole slot may be formed so as to have the enlarged portion centrally thereof, in which case the slide would be arranged to be releasably located in three positions. The peg 34 and the holes 35 may be replaced by a spring-loaded plunger selectively engaging recesses. More than one headed screw may be carried on a common slide. The Provisional Specification describes also the base member being formed as a metal pressing and being releasably located by a dimple thereon engaging recesses or apertures on the slide.

Abstract: 1,063,211. Stamping. NATIONAL RESEAKCH DEVELOPMENT CORPORATION. Aug. 9, 1963, No. 30600/62. Heading B3Q. Explosion forming apparatus, Figs. 1-4 (not shown), comprises a water-and-explosive chamber (41, Fig. 1 ) of steel and concrete beneath the work (42), which is secured between plates (43,44) by fluid-pressure clamps (49). These have clamping members (52) extending through flanges (45, 46) on the chambers (41, 47) and co-operating with wedge-gags (56) positioned by fluid pressure. Water is supplied through a valve (39), and the explosive (65, Fig. 3) is carried on the end of the piston rod (28) of an hydraulic jack (29) extended to expose the explosive carrier (27) above the surface of the water during positioning of the explosive. This is mounted on a base (58) of rubber etc. which protects collets (61, 62) holding the detonator heads (63, 64). The collets are carried on a head (66) on the piston rod (28), the upward movements of which are transmitted to the carrier (27) by springs. The carrier is mounted on a sleeve (30) sliding in a bearing (31), rotation of the sleeve being prevented by engagement of a peg (33) on the sleeve in a slot (34, Fig. 1). A micro-switch may be operated by a flange (32) of the sleeve (30) when this is at the bottom of its travel, completing the firing circuit. The apparatus may be operated automatically or substantially automatically with two upper chambers (47a, 47b, Fig. 4) on the ends of a pivoted and vertically movable arm (70), co-operating with a single lower chamber (41) at one station. At another station, the upper chambers (47) entrain, as by suction, a blank from a hopper (72), or the blank is punched from a strip (73), the punching action being carried out by operation of the arm (70). The following station affords an opportunity for effecting any preparatory work on the blank, while that at the opposite end of the arm is discharged on to a conveyer (74) and a new charge is placed on the carrier (27). The chamber (41) may contain a plurality of explosive charges and be re-entrant in a number of places.
