Title: Automatic brake adjuster mechanism
Inventor: HOLCOMB ORLA LEROY
IPC: F16D66/02
Filed: 1967-12-29
Abstract: 1,204,033. Automatic wear adjustment; disc brakes. BENDIX CORP. 29 Dec., 1967, No. 59152/67. Heading F2E. Relates to automatic wear adjustment mechanism e.g. for an aircraft wheel disc brake having a brake stack including a plurality of stators and rotors (Fig. 1, not shown) which are axially movable on a non-rotatable torque tube and clamped together, when braking, by a pressure plate actuable by a plurality of fluid motors, wherein a plurality of wear adjusters are circumferentially spaced relative to the pressure plate. Each wear adjuster comprises a tubular spring follower 44 (Figs. 2, 3) which is movable between two stops 46, 48 against a return spring 52. Inside the follower is a deformable ductile tube 60 (e.g. of aluminium or copper) which abuts a flange 64 on the follower and has a re-entrant portion clamped to one end of a pin 42 by a sleeve nut and washer, the other end of the pin being attached to a pressure plate 20. The normal brake clearance is equal to the distance between the stops 46, 48 and when the brakes are applied the movement of plate 20 is transmitted via the pin 42 and the deformable tube 60 to the follower 44 causing it to move to the stop 48. However if the linings are worn the pressure plate travel will exceed that available to the follower the difference in travel being absorbed by deformation of the tube 60, as shown in Fig. 3, the inturned portion of the tube increasing and the outer portion decreasing in length. When the brakes are released, the follower 44 is moved back to the stop 46 by a return spring 52. The spring force is inadequate to alter the deformation of the tube so that the axial spacing between plate and follower and hence the brake clearance are thus adjusted for the next brake application. In an alternative embodiment Fig. 5 (not shown), there is an expander button on the end of the pin which button is received in the deformable tube bore and acts to expand the tube diameter as the braking force is applied, the button being thus locked in the tube and adjustment performed. In a further embodiment Fig. 4 (not shown), movement of the pin on braking increases the length of the larger diameter portion and decreases that of the smaller diameter portion of the deformable tube.

IPC: C06F1/20
Abstract: 591,643. Match-book machines. SHAPIRO, J. May 15, 1945, No. 12201. [Class 94 (i)] The match-book receiving, reversing, and delivery mechanism of a match-book-making machine comprises a rotatable shaft 50, Figs. 3, 5 and 6, mounted on a fixed support 30, and to which is fixed a head 39 on which are mounted alternately two stationary match-book receivers 42 and two rotatable receivers 46, spaced at 90 degrees. A stationary gear 36, Figs. 3 and 6, extending into the head 39, is held in a bore 34 in the support 30 by a split clamp 33, and clamp screw 37 lying in an annular grove 38 in the sleeve portion 36' of the gear 36. The rotatable receivers 46 are mounted on a shaft 51 carrying a pinion 49 engaging the gear 36. The shaft 50 is rotated in successive steps of 90 degrees by means of a ratchet mechanism 73, 79 actuated by a rod 86. A roller 63 on a block 60, pivoted about an axis 62, lies in one of four grooves 56 spaced at 90 degrees on a finger-lifting disc 55 which rotates with the shaft 50, so that a finger 65 rests on the receiver 46 or 42 and is lifted therefrom during the rotation of the shaft. Each match packet is advanced into the uppermost receiver and after a quarter-turn of the shaft is pushed from the receiver, now at the side, on to a stacking table. During a quarter-turn of the shaft the rotatable receivers are rotated through 180 degrees, so that the packets are delivered with their wider and narrower ends alternating. The teeth of the gear 36 which are in mesh with the pinion at the stopped positions tend to wear, and by removing the screw 37 the gear can be disengaged and rotated so as to re-engage with unworn teeth in the stop positions. Specification 592,636 is referred to.

Filed: 1968-12-17
Abstract: 1,205,688. Flying shears. I. UNGERER. 17 Dec., 1968 [19 Jan., 1968], No. 59904/68. Heading B3W. In a flying shear, the knives are driven by a crank or eccentric to move in the direction of travel of strip to be cut at an adjustable speed so that the length of the cut sections can be varied regardless of the speed of travel of the strip. As shown, the upper knife 3 is carried by a rocker 2 mounted on a crank-shaft 1, another crank angularly spaced on the same shaft driving a connecting rod 6. The rod 6 is connected to a constraining rocker 9 by a hinge 7 which on rotation of the crank-shaft 1 oscillates through a predetermined point and is connected to the knife rocker 2 by a coupling rod 8. The pivot 10 of the rocker 9 is adjustable along a chord B of a circle about the predetermined point. With the pivot 10 in the full line position the knife 3 describes the orbit a-a having a major axis l when the crank-shaft is rotated in the direction A at velocity u. To increase the cut length, the crank-shaft speed is reduced and the pivot moved in the direction B to increase the orbit of the knife 3 to e.g. b-b so that the knives still travel at the same speed as the strip. The lower knife may be reciprocated by a crank-shaft through gears (13), (14), Fig. 2 (not shown), from the crank-shaft 1. Gears having different transmission ratios may be used to provide for miss-cutting.
