Title: Improvements in or relating to apparatus for pressing shoe parts
IPC: A43D25/06
Filed: 1951-03-27
Abstract: 706,336. Shoe-bottom presses. BRITISH UNITED SHOE MACHINERY CO., Ltd., and MAWBEY, L. March 26, 1952 [March 27, 1951], No. 7029/51. Class 17(1) With a view to facilitating correct alignment of the work and safeguarding of the operator in a machine such as that described in Specification 680,772, wherein a very short period of pressing time is required, the abutments are first lowered into engagement with the work at toe and heel so that, after it has been correctly aligned and, on further operation of a pedal control member, power means are operated to cause sole attaching pressure to be applied. The illustrative form of machine has a single station and is for attaching rubber soles. Correct positioning of the shoe to be operated upon relative to toe and heel abutment members 34, 32, respectively, adjustably mounted on a bar 36 is checked by first depressing, by a pedal 20, a lever 64 attached to yoke member 56 mounted on a shaft 54, to cause to be depressed by a cam roll 60 and cam 58 a bracket 48, on which a forked arm 72 which carries the bar 36 is pivotally mounted between adjustable . stops 96, 78. A spring 50 tends to restrain movement of the arm 72. Further depression of the pedal 20 brings a different portion of the cam 58 against the roll 60 to serve as a positive support against upward pressure of the shoe against the abutments 32, 34. The remaining pedal movement is arranged to trip a one-revolution clutch to rotate an eccentric 28 to raise the pad box 30, through a spring 102, the strength of which may be adjusted by turning the hexagonal head of a screwed stem 108, against the shoe bottom until the upper face of arm 72 engages an abutment 76.

Abstract: 737,601. Pulleys. CABLE BELT, Ltd. April 12, 1954 [March 13, 1953], No. 7036/53. Class 80 (1). A driving pulley for a rope or cable drive wherein the rope may be wrapped several times around the pulley has a tread formed by a plurality of longitudinally-grooved barrelshaped drums 23 which are rotatable about spindles arranged substantially chordal with respect to the pulley. The pulley comprises side members 10, 11 stiffened by radial webs and having interfitting bosses 14, 15. The drums are rotatable on spindles which are carried by a circumferential array of blocks 12. In the construction shown the grooves are parallel to the drum axes and the spindles are a loose fit in the blocks 12 so that the drums may incline to the central plane of the pulley to correspond with the position of the rope. Each groove has a part-circular section, the number of grooves exposed by the flanges 25 corresponding to the number of times the rope is to be wrapped around the pulley. As shown, the flanges are out of symmetry with the central plane of the pulley so that the rope tension tends to rotate the drums, but it is stated that the flanges may alternatively be disposed symmetrically. In a modified construction the drums 23 rotate about fixed axes and the grooves therein are slightly inclined so as to lie on a helix about the pulley tread. In this construction the drums are formed at their ends with rings of intermeshing gear teeth to ensure their simultaneous movement.

Title: Improvements relating to fluid pressure braking apparatus for railway and like vehicles
IPC: B60T15/18
Filed: 1954-03-16
Abstract: 739,475. Fluid-pressure brakes. WESTING- HOUSE BRAKE & SIGNAL CO., Ltd. March 16, 1954 [March 17, 1953], No. 7588/54. Class 103 (1). A known type of triple or distributer valve for fluid pressure railway brakes comprising diaphragms s and S which deflect in accordance with brake pipe pressure to supply or exhaust the brake cylinder is modified by the addition of further diaphragms s<SP>1</SP> and S<SP>1</SP> which give to the valve assembly a variation of brake cylinder pressure with pressure drop in the brake pipe of the kind shown in Fig. 4 as compared with that for the unmodified valve as shown in Fig. 2, which is undesirably steep for operation of the brakes at low cylinder pressures. The space between the two diaphragms S<SP>1</SP> and s<SP>1</SP> is open to atmosphere by port A<SP>1</SP>, the space above the diaphragm s<SP>1</SP> is connected to the control reservoir, and the space under the diaphragm S<SP>1</SP> to the brake cylinder. The normal diaphragms S and s give the valve assembly a characteristic curve as shown by the part 9a. The diaphragms s<SP>1</SP> and S<SP>1</SP> do not have any effect until the brake cylinder pressure is sufficient to overcome the effect of control reservoir pressure acting above s<SP>1</SP>, whereupon they deflect upwardly to engage the main assembly and the brake cylinder against brake pipe pressure variation curve assumes the slope of the part 9b. As shown in Figs. 5 and 6 the valve assembly is modified to vary the braking characteristics according to whether the vehicle is empty or loaded. When the vehicle is loaded the cock 5 is set in the position shown in Fig. 6, in which the space below the diaphragm S<SP>1</SP> is connected to atmosphere through port A<SP>2</SP> and the brake cylinder is connected to the space above a piston 2 which is moved to cut off the auxiliary reservoir RA at a predetermined brake pressure to prevent over-braking of empty or lightly loaded vehicles.
