Title: Improvements in vehicle brakes of the internal shoe drum type
IPC: F16D65/56
Filed: 1963-11-07
Abstract: 1,010,625. Internal shoe drum brakes. H. TEVES, E. A. TEVES, and M. TAUSEND, [trading as ALFRED TEVES MASCHINEN-UND ARMATURENFABRIK K.G.]. Nov. 7, 1963 [Nov. 19, 1962], No. 43969/63. Heading F2E. In an internal shoe drum brake having a turnbuckle type slack adjuster operated by a cable attached to one of the brake shoes, the cable operates a lever pivoted to a stationary member and having at its operated end a slide block which is slidable axially in the slackadjuster casing and is connected internally of the casing to a bush having sprung helical teeth engageable with corresponding helical teeth on a sleeve, the sleeve being rotated by ratchet operation of the sprung teeth when axial movement of the bush corresponding to excessive wear takes place, rotation of the bush causing opposite axial movement of two tappets engaging threads of opposite hand in the sleeve to compensate for the wear. As shown, Fig. 3, the adjuster casing 39 has a slot 45 for guiding axial movement of slide block 29 which is screwed into the bush 43. Leaf springs 44 secured within an annular recess within the bush extend circumferentially and have inwardly bent ends providing spring helical teeth which co-operate with helical teeth 42 on sleeve 41 of the turnbuckle. Tappets 12, 13 whose shanks 46, 47 engage threads of opposite hand within the sleeve 41 engage the webs of brake shoes 5, 6. In one brake embodying the adjuster, Fig. 1, the shoes are slidably and pivotally mounted on the tappets and are operated as leading and trailing shoes in the direction of rotation of drum 3 shown by the arrow, by an hydraulic cylinder 2, rotation in the opposite direction causing operation as a servo-shoe brake owing to sleeve 41 being permitted slide in one direction in casing 39 but being prevented from sliding in the opposite direction by a shoulder engaged by an enlarged end 48 of the sleeve. Lever 26 which carries the slide block 29 is pivoted at 27 to back plate 1 and is connected by cable 17 to shoe 6, the cable passing through a sheath 18 anchored on lugs 21 of the cylinder 2 and casing 39, respectively. In the embodiment of Fig. 2, the cable connects the lever 26 to shoe 5, shoe 6 being mounted for circumferential movement through a link 31 on a carrier 34 which engages the respective piston of cylinder 2 and the respective tappet of the adjuster. The cable sheath is anchored on lugs 35, 22 on the carrier and casing 39, respectively.

Patent GB-442132-A (GB)
Abstract: 442,132. Calculating- machines. TELEFONAKTIEBOLAGET L. M. ERICSSON, 33, Kungsgatan, Stockholm. June 29, 1934, No. 19279. Convention date, July 1, 1933. [Class 106 (i)] The intergeared pinions of an adding and subtracting totalizer are mounted in a frame supported by coaxially pivoted arms so arranged that when the arms are rotated relatively the totalizer frame is subjected to a combined translation and rotation whereby the totalizer pinions may be engaged with the actuating means in an adding or in a subtracting sense as desired. When the machine is operated, a bar 4 moves to allow the differential actuators 1 to rotate clockwise under the action of springs 3 until arrested by key-set stops, the actuation of the totalizer taking place on the return movement of the actuators. The totalizer comprises sets of inter-geared pinions 15<1>, 15 mounted in a frame 14, Fig. 9, the pinion 15<1> being engaged with an intermediate wheel 9 in addition and the pinion 15 in subtraction. The frame 14 is supported by a pair of arms 17, 18, Fig. 9, pivoted at 19 to a link 22 pivoted about the shaft 7 of the intermediate wheel 9. The arm 17 has a depending arm portion 23 and the arm 18 a depending arm portion 24, the arms 23, 24 being pressed together by a spring. A lever 28 pivoted about the shaft 7 has pins 26, 27 positioned between the arms 23, 24. When the lever 28 is rocked anticlockwise by a link 29, the link 22 swings until it contacts with a stop 41 and the pins 26, 27 then separate the arms 17, 18 so that these arms lower the pinion 15 into engagement with the intermediate wheel 9. The link 30 rocks the lever 28 clockwise to lower the pinion 15<1> into engagement with the intermediate wheel. To the arm 17 is secured another arm carrying a bar 40 which normally engages the teeth of the pinion 15<1>, but is removed therefrom during the engaging movement of the totalizer. Transfer mechanism. The differential actuator 1 drives a segment 8, Fig. 7, connected by a spring 12 to the intermediate wheel 9. A pin 10 on the wheel 9 projects through a hole 11 in the segment 8. Prior to actuation, the pin 10 engages an arm 13, Fig. 4, of a transfer lever, the spring 12 being tensioned. During the return (anticlockwise) movement of the actuator i, the totalizer pinions 15<1> or 15 engage the intermediate wheel 9 and this wheel 9 and the segment 8 rotate together until the pin 10 meets the arm 13, the segment 8 finishing the movement alone and stressing the spring 12. If transfer occurs, a projection on the pinion 15<1> or 15 rocks the lever 13, the lever being latched by a latch 34. The pin 10 is not then obstructed by the lever 13 and the intermediate wheel 9 moves with the segment 10 to give an extra step of movement to the totalizer. The lever 13 is restored by a pin 37 and the latch 34 by a pin 38 on an automatically-rocked plate.
