Title: Adjuster for Drum Brakes
IPC: F16D65/56
Filed: 1968-06-12
Abstract: 1,188,255. Adjusters for internal shoe-drum brakes. BENDIX CORP. 12 June, 1968 [28 June, 1967], No. 27916/68. Heading F2E. Automatic adjustment of an internal shoe down brake to compensate for wear in the brake lining is carried out using a screw and nut type assembly, one part of which is carried by a fixed anchoring member and the other part, arranged to abut the associated brake shoe end when the brakes are released, being rotated by pivotal movement of a lever pivotally connected at one end to the brake shoe and provided at its other end with cam surfaces, inclined to the axis of the assembly, which are engaged by a cam follower carried by the other part of the assembly. The brake shoes 14, 16, Fig. 1, slidably mounted on a base-plate 12, are operated by fixed brake cylinders 22, 24 and retracted by springs 31-34 connected between the shoes and fixed anchoring members 26, 28. One end of each shoe is located and held against lateral movement between parallel flanges 36, 39 formed at one end of each anchoring member, the other adjacent ends of the members and shoes being connected by wear adjusting devices 37, 40. Each device comprises a screw 43, Fig. 3, provided with an enlarged head 46 which an adjacent part of the brake shoe abuts when the brake is released, which head is formed at its circumference as a ratchet wheel 48, and a nut 57 formed in the anchoring member. A V-shaped axially slidable, non- rotatable spring clip 50 is located in grooves 58, 59 around the nut with its apertured end 53 frictionally held, by snap ring 56 engaged in a groove in the screw, against the head of the screw. The clip 50 carries a pin 72, see also Fig. 1, which extends into a slot 70 having cam surfaces 73 in a lever 62 pivotally mounted on the brake shoe so that when the brake is energized and the shoe moved against the drum 18, the lever is pivoted by the action of the pin in the slot. An inwardly extending pawl 74, Fig. 4 (not shown), is formed in the lever to engage the teeth on the ratchet wheel 48 so that as the lever is pivoted the pawl causes the ratchet wheel and therefore the screw to be rotated. The length of movement of the shoe between braking and rest positions is correspondingly reduced. The adjustment may be effected on application or release of the brake, no specific details being given of a construction to effect the latter mode of operation. Manual adjustment of the ratchet wheel may be made through a closure member 76 in the backing plate 12. In an alternative embodiment it is stated that the lever 62 may cause rotation of the nut 57, the screw being held stationary.

Abstract: 408,884. Quotient and mean speed indicators. SALOMON, F. M. M. B., 3, Rue de l'Universite, and GOVARE, H. P., 4, Rue Guy de Maupassant, both in Paris. Oct. 20, 1932, No. 28260/33. Convention date, Dec. 7, 1931. Divided on 408,702. [Classes 106 (iii) and 106 (iv).] Spiral cams for evaluating logarithmic functions for use in quotient indicators and more particularly in mean speed indicators are made with several cam surfaces each engaging an independent element on a lever and operating in succession, but with an overlapping period. An independent spiral cam returns the lever, the cam element rotating continuously. The continuously rotating plate 65 is formed on one side with logarithmic spiral surfaces R1, R2, R3 which engages in succession, pins E1, E2, E3 on one arm of an element 66 oscilating about an axis 67<1>. The direction of movement is such that the pins are moved away from the axis 67 of the cam plate. On the other face of the plate 65 is formed a cam R4 which engages a pin E4 on the other arm of the element 66 to effect the return movement. Time and distance cams constructed in this manner are applied to a mean speed indicator also shown in Specification 408,803. At the beginning of the movement, the true logarithmic contour is slightly varied to avoid an indefinite indication of mean speed due to the smallness of the space and time movements. Specification 349,338 also is referred to.
