[Class 44.] Apparatus for arranging the fastening elements of sliding- clasp fasteners on parallel stringers comprises a rotating internal toothed wheel 4 which carries the elements between its teeth from a scoop 2 to a slide 13. Elements which are not properly positioned between the teeth are removed by ejectors 14, 15, 16. On reaching the slide the correctly positioned elements are forced down the slide by a spring 17. At the lower part of the apparatus they drop upon a transverse slide 20 and they pile up one upon another until they reach a reciprocating feeler 28. Should the slide 13 be filled to such an extent that the feeler on moving back strikes the pile of fasteners it is held in the retracted position.

Abstract: 1425196 Spot-type disc brakes; slack adjusting KELSEY-HAYES CO 17 May 1973 [18 May 1972] 23691/73 Heading F2E In a self energizing floating caliper disc brake having a floating caliper 15 a tilting member 35 is located between the flat surface 45 of a cupshaped member 43, provided in a cylindrical bore of a pad backing plate 21 for tilting movement of the tilting member, and a pin 32, engaging in a pocket 31 of an actuating shaft 28 whereby if a rotor 12, rotating in the direction 81, is to be braked by pads 18, 19, on actuating lever 62 and shaft 28 are pivoted in an anticlockwise direction thereby transmitting an axial force through pin 32 to the tilting member 35. Pad 18 has limited circumferential movement through a flange 49 thereof engaging in a caliper recess 51, and cup-shaped member 43 follows this movement to cause member 35 to pivot first about a spherical surface 34 thereof and then about a shoulder 38 thereby causing a further axial force to be applied upon brake pad 18 to provide a self-energizing action. The centre of curvature of another spherical surface 44 at the bottom of member 35 is coincident with that of upper surface 34, so this force always passes through the same point regardless of the pivotal position of member 35. A return spring 82 engages a surface 83 of caliper 85 and a shoulder 84 on member 35. Slack - adjustment.-An adjusting lever 66 rotatably and axially supported on a portion 67 of shaft 28 has an offset tang 68 extending in a slot 69 formed in actuating lever 62. A torsion spring 71 encircles portion 67 and has its ends 72, 73 respectively engaging into slot 69 and a flat 74 of lever 66 to exert a clockwise force thereupon so that tang 68 engages one end of slot 69. A rotatable adjusting member 55, threaded to caliper leg 16, has ratchet teeth 75 engaged by a pawl 76 integral with lever 66 under the bias of a spring 77. On counterclockwise roation of lever 62, pawl 76 rotates in the same direction due to the tang 68 and slot 69 engagement and, if sufficient lining wear has occurred, engages the next of teeth 75. On return movement of lever 62, spring 71 forces lever 66 to follow and causes rotation of adjusting member 55 through the ratchet and pawl connection to advance a supporting member 29 and all associated components via contacting shoulders 56, 57. In the construction shown the actuating lever 62 is rotated mechanically through a wire from a distant actuator. A service actuator may also be provided.
