Title: Automatic slack adjuster
IPC: F16D65/54
Filed: 1963-04-19
Abstract: 981,169. Brake adjusters. ROCKWELL-STANDARD CORPORATION. April 19, 1963 [June 1, 1962], No. 15490/63. Heading F2E. Automatic adjustment of a brake actuating camshaft 10, e.g. to allow for wear of the linings of an internal shoe drum brake having a back plate 12, comprises an applying lever 16 having a hollow hub 19 provided on its interior periphery with a series of recesses 36, a drum member 21 splined to the shaft 10 and consisting of a cylindrical part having deep grooves 26 cut in it in planes parallel to the axis of shaft 10 and arranged chordally at right angles to each other as shown, and locking plates 30 slidable in the grooves, each plate having one or more slots to receive a spring or springs 32 and an anchor pin or pins 33, inserted in bores 34 in the drum, for urging the plates towards the recesses 36. The arrangement is such that only one of the plates 30 fully engages within a recess 36 at any one time and in this position forms a positive driving connection when lever 16 is moved in the brake applying direction, e.g. by a pneumatic motor 20 having a release spring 20b, so that shaft 10 is rotated to apply the brake. An adjuster plate 44 is rotatably mounted on a reduced diameter portion 25 of the drum 21 and has a series of inwardly facing ratchet teeth 55 adapted to be engaged by pins 59 slidable in axially arranged bores in the drum and urged towards the plate 44 by springs 62. Rotation of plate 44 is limited by a pair of abutments 63, 64 co-operating with a pin 65 on the back plate 12. Seals 43, 52 respectively located in annular grooves in the flange 23 of the drum and in the plate 44 seal the mechanism within the hub 19 and also provide a frictional connection between the hub 19 and plate 44. As a result, when the brake is applied plate 44 rotates with the drum through the angular distance A between the initial position of engagement of pin 65 with abutment 64 and its position of engagement with abutment 65, after which, if brake travel is excessive, the continued rotation of the drum causes the pins 59 to slip one of the teeth 55 whereby, on release of the brake, return movement of the drum is arrested in a new position to compensate for wear of the brake linings. Lever 16 can, however, return to its initial position since in this direction of rotation the plates 30 are moved inwardly along the slots 26 by camming action of the recesses 36 so that they ratchet to cause a different one of the plates 30 to engage a recess 36 of the hub 19. The mechanism within the hub is lubricated via an opening 53 closed by a plug 54. Additional bores 34<SP>1</SP> are provided in the drum as alternative mountings for the pins 33 whereby the plates 30 may be reversed so that left- or right-handed operation is provided for. Plate 44 is interchangeable for the same reason. The plates 30 may have double chamfered ends to ensure they do not jam against the walls of the recesses 36 (Fig. 6, not shown), the recesses 36 having rounded or chamfered edges for the same reason.

Abstract: 713,501. Disintegrating paper pulp by agitation &c. BLACK-CLAWSON CO. June 20, 1952 [Nov. 7, 1951], No. 15582/52. Class 96 Paper pulp is disintegrated by a rotating disc 30, Fig. 1, in the floor of a tub 20, the disc having two rings of spaced blades or vanes 52, and 54 plus a single blade 60 shaped to send a jet of pulp over the surface of an inclined screen 42 to sweep it clear of any obstructions not dislodged by the flow generated by the other blades of the disc &c. Reduced pulp passing through the screen 42 flows via an outlet 44 to a regulating-box 45 with a vertically adjustable dam. Trash is thrown through an opening 72 to a passage 71 divided by a baffle 75 into an upper and a lower branch (76 and 77) both branches leading to a tower 70, small fibrous pieces being allowed to return to the tub 20 through the opening 72. Larger pieces of trash rise in the tower 70 and are deflected by a baffle 86, Fig. 3, collected by a bucket conveyer 80 and dumped into a receptacle 84. The disc 30, Fig. 1, is driven by' a pulley 26 &c. geared at 25 to a vertical shaft 27, a cap 51 on the top of which minimizes accumulation of pulp above the centre of the disc. In a modified form suitable for batch operation, the cap 51 is larger and provided with vanes. A modified pulping-engine with the tub and impeller made of welded - sheet metal is described.

Abstract: 144,668. Williams, L. M., Williams, P. J., and 'Williams, C. L. Nov. 4, 1916, [Convention date]. Controlling-apparatus, arrangements of hand, foot, and transmission gear in conjunction with; flexible transmitters.-The throttle is controlled separately by hand and foot levers, so that each acts indeper.- dently of the other. The hand-lever 40 operates a crank 22 connected to a rigid tube 27 having a sliding collar 35 which is connected to the throttle lever 25. The foct lever 7 operates a Bowden cable the inner wire 11 of which is fixed to the sliding collar 35, while the outer member 17 slides with some friction in the tube 27 under control of a spring-pressed plunger 41. A spring 38 is compressed between the sliding collar 35 and a fixed collar 39. When the throttle is fully open, a projection 45 on the arm 25 comes against a stop 46. Thus if the throttle is closed, it can be opened by either hand or foot lever, while, if the throttle has been fully opened by either lever, operation of the other merely causes movement of the outer member 17 of the Bowden cable within the tube 27.

Title: Improvements in or relating to projectors for slide transparencies
IPC: G03B23/04
Filed: 1964-04-16
Abstract: 1,060,413. Slide projectors. T. GANZ and A. GANZ-KEYSER. April 16, 1964 [April 16, 1963], No. 15862/64. Heading G2J. A motor-driven slide projector has two magazines 10 on opposite sides of the optical axis, and a slider 15 accommodating two transparencies 2 which is movable between the two magazines whereby transparencies are moved in turn from each magazine for projection and back again. A shutter operates during the change. The magazines have partitions 12 forming slide compartments open at the top and inner side, and are Indexed on rails 11 relative to slider 15 by means of studs 32 entering sleeves 31 which are driven longitudinally by their spring-loaded engagement with screw-threaded shafts 30. These shafts are driven in one-revolution increments by reversible motors 36 whose control switches 38 are operated by cams 37 on each shaft 30. At the end of their motion on shafts 30, sleeves 31 operate switches 39 to stop motors 36. A pivoted sensing arm engages the inner edges of slides 2 and when no more remain in the magazine its resulting movement operates a reversing switch for motor 36. Slider 15 has a rod 20 sliding in brackets 19 and is driven through a rack and pinion 17 by a reversible motor, the two slides being held between arms 16. The slide in the projection position is pressed by spring-loaded pin 23 against centering blocks 27, the pin being operated by electromagnet 25 and arm 24. At each end of its motion, the slider operates a switch to index the magazine receiving one arm of the slider and so introduce a new slide which is transferred to the optical axis on the next movement of slider 15. Further operation of the master switch then starts this return movement.

Title: Marine drive unit
IPC: B63H20/20
Filed: 1964-04-17
Abstract: 1,002,715. Internally meshing gear pumps; hydraulic apparatus. HYDRO DRIVE CORPORATION. April 17, 1964 [April 22, 1963], No. 15993/64. Headings F1F and F1P. [Also in Divisions B7 and F2] A rotary oil pump 24 for use in a hydraulic system in an outboard drive unit for boats (see Division B7) comprises an input shaft 48 having a rotor 122 with rearwardly projecting teeth 123. Teeth 123 mesh with the teeth 124 of an eccentrically mounted idler gear 125 which rotates on a stud 126 which projects from back plate 127. At its front, the back plate has a forwardly projecting partition 136 located diametrically opposite the location of intermesh of teeth 123, 124. At its back, the back plate has a stop 137 having parallel faces arranged to engage a face of cap 128. With shaft 48 turning anticlockwise as viewed in Fig. 17, a stop face engages the face of cap 128 and locates partition 136 as shown. If the rotation is reversed the friction drag of idler 125 on the back plate 127 causes it to turn clockwise until the opposite stop face of stop 137 engages the face of cap 138, and thereby positions the partition 136 opposite the position as shown in Fig. 17. Thus the discharge port 132 for the pump remains the same for both directions of rotation of shaft 48. The hydraulic circuit (see Fig. 18) comprises said pump 24, a control block, clutches 25, 26 and hydraulic cylinder unit 10. When the outboard drive unit is required to be elevated, e.g. for use in shallow water, the shuttle valve 149 of the control block is positioned as shown to prevent flow to the clutches and a plug valve 161 is turned through 90 degrees to allow fluid to charge the underside of piston 143 and expand unit 10. The valve 161 is then turned a further 90 degrees to lock the unit 10 in the extended position. For forward drive the shuttle valve 149 is moved to the right to charge clutch 25. When in the normal forward drive position, plug valve 161 is positioned as shown so that the spaces above and below the piston 143 are vented to sump 23 (Fig. 3, not shown). This venting allows unit 10 to act as a shock absorber if the outboard drive unit strikes an underwater obstruction. Finally for reverse drive, shuttle valve 149 is moved to the left charging clutch 26 and also the upper part of unit 10 to prevent the outboard drive unit from lifting away from the boat to which it is attached.

Abstract: 355,351. Boot-making machines. UNITED SHOE MACHINERY CORPORATION, 140, Federal Street, Boston, U.S.A.-(Assignees of Bazzoni, L. J. ; Swampscott, Massachusetts, U.S.A.) May 24, 1930, No. 16027. Convention date, June 28, 1929. [Class 17 (i).] Heels, covering; trimming.-A machine for use in covering channelled heels comprises positioning means for the heel and means for tucking the marginal part of the cover into the channel. Preferably, means are provided for trimming the cover, the two operations being performed at different stations in the machine. The tucking blades 50, Fig. 6, are adjustable about pivots 40, Fig. 3, the carriers of the blades being geared together for equal angular movement and being clamped in adjusted position by screws 48, Fig. 1, engaging slots. This mechanism is mounted on arms 36 pivoted on a shaft 34 and continued beyond the shaft as a lever 68 having at its end a roll 70 on an eccentric adjustable pin, the roll engaging a cam on a power shaft 24. A heel holder comprises a pair of arms 80, 82 pivoted at 84 and urged apart by a spring 92. To clamp the arms on the heel, a handle 100 is pivoted at 96 to one arm and operates a cam 94 engaging a screw 102 emerging from a casing 108 secured to the other arm. In order that the clamps may engage the heel with adjustable resilient pressure, the screw 102 is threaded into a nut which can slide but not rotate in the casing and is backed by a spring adjustable by a screw 112. The arm 80 is linked to a cam-operated. arm 122. The trimming mechanism comprises shear blades 136, Fig. 3, adjustable towards and away from each other, and blades 150 adjustable in height and transversely of the machine, mounted on slides operated by cams 156. The cam shaft is driven by a worm on the shaft of an electric motor 30, Fig. 1, through a one-revolution clutch actuated by a treadle-rod 168. In operation, the heel 64 is placed with its channels in engagement with the blades 50, the handle 100 depressed and the clutch tripped. The arms 36 then descend and the heel moves to trimming position over the shear blades 136, the edges of the cover overlapping the edges of the blades. The knives 150 move inwardly and trim the margins of the cover, and the heel moves back to its original position, the blades 50 wiping the edges of the cover inward in the latter part of this movement. The arms 36 then move upwards to tuck the margins of the cover into the channels simultaneously on the two sides, and the machine comes to rest. The heel may then be released by lifting the handle 100 and a new workpiece positioned. Specification 296,401, [Class 17 (i), Boots and shoes, Apparatus for making &c.], is referred to.
