Abstract: 1340802 Switchgear structures; switch cases SQUARE D CO 19 April 1972 [28 April 1971  (2)] 18239/72 Heading H1N A motor starter unit is provided for use in association with a circuit-breaker and a panelboard having a stack of flat, elongate, bus-bars on either side of which the circuit breaker may be selectively mounted with terminals at one end plugged on to the bus-bars, the said starter unit comprising a box having mounted therein a circuit-breaker operating mechanism which is connectible to the circuit-breaker operating member when the box is mounted on the panelboard, the operating mechanism including an external handle and being mountable in the box selectively in either of two angularly displaced positions in accordance with the selected side of the stack of bus-bars on which the box and breaker are mounted such that similar movements of the external handle produce the same sense of movement of the circuit-breaker operating member with respect to the stack of busbars, whichever side of the bus-bar stack the box and breaker are mounted. As shown, a box 21 has feet 26a by which it can be secured to a panelboard (such as that disclosed in Specification 1,161,030) on the left or right of a stack of bus-bars thereon. The box 21 has a relatively deep compartment 21f containing a motor control unit (not described) with buttons 38, 40, 42 and pilot lights 39, 41, and a relatively shallow "overhanging" compartment 21g accommodating an operating mechanism 24 with a handle 44 for operative connection to a moulded-case circuit breaker (not shown) which may be mounted on the panelboard beneath the compartment 21g and in connection with the bus-bars. According to the position of the box (and circuit breaker) with respect to the bus-bars the mechanism 24 is secured in the box 21 by engagement of keyhole slots in the mechanism support frame with four of the eight screws 84 in the compartment 21g such that the mechanism 24 is to the left (as shown) or, alternatively, it may be rotated 180 degrees and fitted to the right (Fig. 4, not shown) using the other four screws 84. A hinged cover 22 closes both compartments and has a slot 22b for handle 44 in either mounting position of mechanism 24, the latter carrying an inner pivoted cover member 76a which extends to act as a filler plate for the unused portion of slot 22b. The mechanism 24 includes an actuating member 60 with portions extending laterally which co-operate with an interlock bracket 62 on cover 22 when the mechanism is in the ON condition to prevent opening of the cover 22. The bracket 62 is pivoted on cover 22 by a rivet 82 with a screwdriver slot whereby the bracket may be turned against action of a spring 83 to defeat the interlock. A further interlock member (80, Figs. 6, 7, and 8, not shown) pivoted on mechanism 24 is loaded by a spring (81) to move into interference with member 60 when the cover 22 is opened and then prevents the handle 44 being moved to the ON position.

Title: Disc brake
IPC: B62L1/00
Filed: 1974-04-26
Abstract: 1425285 Spot-type disc brakes for bicycles B F GOODRICH CO 26 April 1974 [27 June 1973] 18415/74 Heading F2E A spot-type disc brake comprises: a support adjacent the disc; two arm members, one on each side of the disc, each arm member having one part generally parallel to and adjacent a flat friction surface of the disc, and a resilient part either integral with or attached to the one part and extending at an acute angle thereto on the side remote from that adjacent to the disc; friction means attached to each arm member and facing the disc; and means for moving the arm member in a direction which increases the angularity of the resilient part, such direction being substantially the usual direction of rotation of the disc, whereby the friction means will engage the disc and the rotation of the disc will increase the pressure of engagement. Fig. 2 shows the application to the rear wheel of a bicycle, the lower member of frame 11 being normally horizontal and the upper member being directed towards the saddle. The brake frame 23 has a closed top, a closed end 32, a flange 29 at its open end and a supporting plate 24 secured at 26 to the frame 11, Fig. 5. An arm member including a lining carrier 36, arranged chordally to the disc, has adhered to it a friction lining pad 34 in which are located the free ends of arms 46, 47, of a wire spring 37 (constituting the "resilient part"), loops 42 in the middle of the spring 37 being snapped into slots 44 in flange 29. Lining carrier 36 extends towards the closed end 32, Fig. 4, of brake frame 23 and has there an opening 52 to accommodate a U-shaped bracket 53, a flange 55 on which contacts the outside of lining carrier 36. Bracket 53 also engages a lining carrier 35 similarly arranged on the opposite side of disc 14. The end of a cable 13 is secured by screw 56 to bracket 53, the cable sheath 57 being secured to end plate 32. In operation the upper part of disc 14 moves leftwards, Fig. 4, arrow B-B Fig. 2; when cable 13 is pulled, bracket 53 is moved bodily leftwards while the other end of carrier 36 and pad 34 move in an arc about a vertical axis lying just to the right of flange 29, Fig. 2, obliquely towards the disc, with accompanying flexure of spring 37 at that axis; carrier 35 and pad 33 move correspondingly. This radial movement is accentuated as soon as each pad contacts the disc, providing a self-energizing action. Figs. 6, 7 show a similar arrangement where the parts of each arm member are formed integrally from a flat spring and a friction lining pad 68 or 69 is hooked on to it at the angle.
