摘要： 575,819. Adjusting brakes. GIRLING, Ltd., and MACE, T. K. April 12, 1944, No. 6758. [Class 103 (i)] In brake shoe adjusting means wherein a wedge member engaged by the shoe ends is movable in a substantially radial slot in the back-plate of the brake to effect the adjustment, movement of the wedge member is effected by a cam rotatable on the wedge member and engaging a fixed abutment. As shown, inclined edges 14, 15 of the ends of the brake shoes 10, 11 engage similarly shaped slots in a cylindrical head 18 provided with a stem 19 having a non-circular part slidable in a radial slot 20 in the back-plate 13. Adjustment of the head 18 in the slot is effected by a cam 21 rotatably mounted on the stem 19 and engaging a stud 22 fixed on the back-plate. The head and cam are clamped in position by a nut 24. The cam may be turned by a finger-piece 25 or by a key or a C-spanner adapted to engage holes or a notch in the cam, or it may have a hexagonal part for engagement by a spanner. The slot instead'of'being radial may be inclined to compensate for unequal wear of the shoe linings.

摘要： 623,797. Vehicle brakes. GIRLING, Ltd., and MACE, T. K. May 15, 1947, No. 13067. [Class 103 (i)] An internally expanding drum brake, of the kind wherein the shoe remains in light rubbing contact in the off condition, has a portion of the shoe lining 12 displaced a small predetermined amount away from the surface of the shoe 10, by resilient means (e.g. spring-loaded plunger 21), which projects through the drum flange, so that only the lining in the region ,of the plunger maintains rubbing contact with the drum lining 15. Alternatively, the plunger may be replaced by a spring-operated lever. Specification 519,787 is referred to.

摘要： 560,455. Lubricators. BENDIX, Ltd., and MACE, T. K. June 26, 1942, No. 8787. [Class 12 (iii)] A rotary pump of the pivoted vane type is mounted on the rotating shaft of a mechanism and forces oil through an axial bore in the shaft to the surface to be lubricated. In Fig. 2, the stator consists of a sleeve k carried by the housing c and having an eccentric bore for a collar h on the rotating shaft which is bored axially. The collar h has a flat p for a curved vane r which engages the sleeve by centrifugal force, the flat having a hole q leading to the shaft bore. The oil is fed from an inlet m or from a reservoir in the housing ; a pin l locates the sleeve within the housing. In Fig. 3, the sleeve s has a concentric bore and a recess u for a spring-pressed vane v which engages an eccentric collar t on the shaft.

摘要： 390,548. Prepayment mechanism for meters. MACE, T. K., 11, Sherbourne Road, Acocks Green, Birmingham. Oct. 14, 1931, No. 28506. [Class 27.] Coin action, thrust and with delivery proportionate to value of coin.-In apparatus operable by any of a number, e.g. two, coins of different denominations and having a single admission slot and coinoperated mechanism which selects automatically appropriate gearing so that the delivery is in proportion to the coin inserted, the coins are inserted through a slot 8, Fig. 2; in the usual price-change plate 4 to a coin pocket 18 on a rotary disc 9 and depress a support 24 against the action of a spring 32, the support being guided by a stem 29 passing through a bracket 28 on the disc 9. A pin 30 engages an inclined slot 23 in a lever 21 pivoted at 19 to the pocket and rocks this lever to bring a portion 49 or 50 thereof into engagement with a ratchet measuring-out wheel 37, according as a shilling or a penny is inserted. The portions 49, 50 are separated by a space 48 to prevent the wheel 37 from being engaged by the lever 21 if a halfpenny is used. The wheel 37 is fixed to a tubular driving-shaft 39 which is connected to a driven shaft 51 through a change-speed gearing, comprising constantly meshing gear wheels, the drive being direct in the case of a penny, and through the change-speed gear in the case of a shilling. The shaft 51 has a threaded portion 72 engaging a nut 73 which is traversed to operate a valve controlling lever 76. The nut is slidably but non-rotatably mounted in the bush of a pinion 74 driven by a wheel 75 and worm gearing by meter mechanism. The shaft 51 has a wheel 53 meshing with one wheel 57 of a pair of planet wheels 57, 58 revolvably mounted in a disc 54 fixed to the shaft 39, the other wheel 58 meshing with an internally toothed wheel 59 loose on a bush 60 which is slidable on the shaft 39 and connected to a push rod 64 by a cross pin 65 passing through a slot 66 in the shaft. The rod 64 is normally held by a spring 69 in such a position that teeth or holes 61 on the edge of the internally toothed wheel 59 engage pins 62 projecting from a plate 43 fixed to the back of the casing 1 containing the coinmechanism. When a shilling is inserted, the wheel 59 remains stationary and the drive from the shaft 39 takes place through the disc 54, and the planet wheels 58, 57. When a penny is inserted, a projection 70 on the lever 21 pushes the rod 64 inwardly and moves the wheel 59 into engagement with pins 63 similar to the pins 62 and projecting from the disc 54. The wheel 59 now turns with the disc 54 so that the planet wheels 57, 58 are locked and the drive between the shafts 39, 51 is direct. The push rod may be provided with grooves and locked in position by a pivoted catch, if it is desired to set the mechanism for use with one coin only. A single planet wheel meshing with both the wheels 53, 59 may be used. In a modification, the rod 64 may be rigid with the measuring wheel 37 and the whole be axially slidable by the lever 21. In a further modification, two spaced rows of teeth, engageable by a single projection on the lever 21, may be provided on the wheel 37 or there may be two measuring wheels both fixed to the driving shaft. Coin-slit closing-devices; fraud, preventing.- The shaft 10 connecting the coin-pocket disc 9 to the operating handle 12 is provided with a pair of flats 11, Fig. 9, and the handle with a slot 15 shaped as shown to allow a slight lost motion between the handle and the disc 9. This allows a wing 13 on the handle to cover the coin-slit 8 before the coin-pocket begins to move.

摘要： 637,058. Universal joints. GIRLING, Ltd., and MACE, T. K. March 22, 1948, No. 8377. [Class 80 (ii)] In a universal joint of the " Tracta " type, as described in Specifications 282,051, [Class 80 (ii)], and 426,532, one intermediate member a has a peripheral groove b for engagement with the driving or driven fork (not shown) and a transverse slot c for receiving the tenon of the other intermediate member (not shown). Mounted in recesses in the side walls of the slot c are part-cylindrical bearing pads d retained in position by arcuate ribs e, their bearing surfaces being slightly proud of the slot wall. The pads, rockably disposed in the recesses, align themselves with the flat surfaces of the tenon thereby spreading the load from the rigid corners of the tenon during bedding down. In modifications, the pads may alternatively be retained by an axial pin, sufficient clearance being given to permit rocking movement, or opposed pads, joined by a bridge piece may comprise a single part, which may or, may not be pivoted on the intermediate member. The bearing pads may also be part-spherical in shape, and may alternatively be housed in the tenon to engage the flat walls of the slot. They may be of die-hardening metal-chrome steel, bronze or antifriction material.

摘要： 576,626. Brakes. PRATT, J. H., IRVING, J. S., and MACE, T. K. June 12, 1943, No. 9493. [Class 103 (i)] An internal expanding brake is applied by a floating lever which engages staggered abutments on adjacent shoe-ends and has a fulcrum arranged to roll on a surface on and inclined to the plane of the back-plate whereby the pressures applied to the respective shoes are unequal. As shown, a lever 18 arranged in a slot in the fixed post 14 and which is connected by a rod 19 to the brake operating means, engages laterally offset extensions 12 , 13 , of the webs 12, 13 of the shoes 10, 11. The extensions 12', 13 are received in notches in the post 14. The shoes are steadied by engagement with the post, of upper and lower cranked parts 16 of the web extensions. A roller 23 on the lever bears upon an inclined track 24 formed at the base of the slot in the post 14. Due to the reaction of this track on the lever through the roller being at right angles to the track the force applied to one shoe is greater than that applied to the other when the brake is applied. The direction of the slope of the track may be such that the greater force is applied to the trailing shoe. Specification 576,625 is referred to.
