Abstract: 1,148,787. Hydrostatic transmission control; controlling hydrostatic brakes; fluid pressure brakes. EATON YALE & TOWNE Inc. 7 Sept., 1966 [21 Oct., 1965], No. 39984/66. Addition to 1,145,094. Headings F2D, F2E and F2F. In a hydrostatic transmission for an industrial truck of the type described in the parent Specification 1,145,094 wherein a fixed displacement pump (FP), Fig. 1 (not shown), supplies a variable displacement motor (VM) through a control valve (CV) which is moved left by a rod 6 to throttle the motor exhaust and effect braking of the motor (VM) when an inching pedal 70 or a service brake pedal 80 is depressed, the inching and brake pedals are connected to the rod 6 through cams 79, 82 so shaped that a predetermined movement of the brake pedal 80 causes a large movement of the rod 6 whilst the same movement of the inching pedal causes a small movement of the rod 6. The inching pedal 70 is fast with a shaft 71 which is rotatably mounted in brackets (72), 73 and fast with the cam 79. The brake pedal 80 is integral with a sleeve 80a rotatable on a fixed shaft 91. Lugs 88 of the sleeve 80a are pivoted to an actuating rod 90 of the track service brake master cylinder and carry a rod 92 which engages a slot 81c in a lever 81b fast with a shaft 81 carrying the cam 82. The cams 79, 82 engage followers 84, 83 pivotally mounted on a rod 78. The followers act on a rod 78a of a yoke 77 which pivots on the rod 78 and is connected to the rod 6. The position of the followers 83, 84 relative to the rod 78a may be adjusted by screws 83b, 84b. Depression of the inching pedal 70 acts through the cam 79 and follower 84 to move the rod 6 slowly and thus slowly throttle the motor exhaust for controlled braking during inching of the truck. On depression of the brake pedal the rod 6 is moved rapidly to a position in which full braking of the motor (VM) is obtained. The full braking of the motor (VM) is effective before the master cylinder develops sufficient pressure to apply the service brakes. Lost motion between the rod 92 and slot 81c permits release of the service brakes before braking of the motor is terminated.

Filed: 1975-10-01
Abstract: 1494040 Rotary impact mechanisms ATLAS COPCO AB 1 Oct 1975 [2 Oct 1974] 40099/73 Heading B3N In a rotary impact mechanism suitable for impact wrenches, a rotating hammer accelerates over more than one revolution before each impact. The hammer 4 encircles the anvil 2 and impacts are transmitted by an impact dog 7 rotatably mounted in a recess 6 in the hammer and having edges (not indicated) which interact with flanks of a recess 5 in anvil 2. The dog 7 is engaged at a cam 8 thereon by a driving hub 10 driven by shaft 9 to rotate the hammer and is turned in its recess into an impact position, Fig. 3 by a cam 12 on a control spindle 11 mounted in bores 14a, 14b in anvil 2 and drive shaft 9, cam 12 engaging the cam 8. After impact the hub 10 returns the dog to its freerunning position (cam 8 extending radially, Fig. 4) whereupon a lock dog 13, which is mounted in control spindle 11 and locks it relative to the anvil by engagement with abutment heel 16 in anvil recess 15, is pushed inwardly against spring 18 by engagement of its cam 20 by release cam 21 on dog 7. This causes the spindle to move slightly but to be still held by engagement of rib 22 on dog 13 with abutment heel 16. After further rotation of dog 7 and hammer 4, the dog again contacts cam 12 on the spindle but this time the dog is not rotated in its recess but spindle 11 is rotated until rib 22 disengages from the heel 16 and the spindle is free to rotate almost a complete revolution until dog 13 again abuts heel 16 whereupon the cycle restarts.

Abstract: 900,897. Screw-and-nut gearing. ANDERSON CO. Nov. 27, 1959 [Dec. 15, 1958], No. 40363/59. Class 80 (3). The threads of a multi-threaded rotary screw 12 are engaged by respective spool-shaped rollers 28 mounted in equally-spaced openings in a carrier 18, each roller having two spaced enlarged bearing-surfaces 29 engaging outwardlyfacing raceways on axially-spaced rings 16, 17 which are urged apart by a spring washer 32. The spring loading maintains all the parts in engagement to compensate for wear and the two rings may move radially relatively to each other during operation to accommodate canting of the rollers due to errors in the lead of the screw or lengths of the rollers. As shown, the screw 12 is driven by a motor and the two rings 16, 17 have thereon pairs of flats 21, 23 engaged by the legs of a bracket 35 carrying the axially-movable load 39. Stops 33, 34 on the screw 12 are engaged by the carrier 18 to limit axial movement of the load 39, the mechanism then " freewheeling " with. the rollers sliding in the raceways. Alternatively the carrier 18 may have axial projections engaging pin-type stops. In a modification, Fig. 5 (not shown), the flats 21, 23 are replaced by part-circular apertures coupled by pins to the load. In a modified construction the load is connected to the carrier 18 so that the rings 16, 17 merely serve to retain the rollers 28 and no " freewheeling " motion is possible. In either construction the rollers 28 may be rotatably mounted in the carrier 18 by pintles, Fig. 8 (not shown), extending beyond the enlargements 29 and engaging grooves in the carrier openings. The pintles may be hardened or provided with bearing means.

Abstract: 1,023,303. Measuring engine thrust. JOHN CURRAN Ltd. Nov. 14, 1962 [Nov. 17, 1961; June 7, 1962], Nos. 41179/61 and 22005/62. Heading G1W. An engine test bench for testing the thrust of jet engines comprises an engine carrier 1 (Figs. 1, 2) on a platform 2 having two converging arms 3, 4 with a cross beam 18 and supported on a fixed base 5 by flexure straps 6, 11. A hydraulic capsule 16 is supported on post 14 fixed to the base 5, and a similar capsule 17 is fixed to the cross beam 18 of the platform 2. The capsules have movable heads, 16b and 17e (Fig. 3) respectively, which abut one another, the head 16b having an adjustable part 16e. Movement of the platform 2 by the engine thrust moves a housing 17c of the capsule 17 and reduces the volume of a chamber 17a between the head 17e and the housing 17c thus actuating a Bourdon tube instrument 19 which indicates the engine thrust. The head 16b is not displaceable by the force exerted upon movement of the platform 2 so long as the volume of a hydraulic compensating circuit (Fig. 3) remains unchanged. This circuit comprises a compensator device 21 having a variable volume chamber 22 defined by a fixed housing part 23a and a diaphragm 24 bonded to a rigid block 25. The block is bolted to a piston 26 movable in a chamber 31 in a housing part 23b and is coupled to a motor (Fig. 4 not shown). When the platform 2 moves due to the engine thrust a projection thereon engages a switch to start the motor which moves the piston 26 so as to reduce the volume of the chamber 22. Liquid is thereby forced through a pipe 140 to the space 16a which causes the head 16b to push the head 17e toward the housing 17c. But, as the housing is rigidly connected to the beam 18 of the platform 2, the platform moves to its original position from which it was moved by the engine thrust, and the relative displacement of the head 17e and housing 17c remains unchanged. During this return movement of the platform therefore the instrument 19 still indicates the engine thrust. The calibration and setting up of the test bench is described wherein a hand operated device 42 (Fig. 3) is provided which is similar to and is arranged in parallel with the device 21. Instead of the hydrostatic capsule 17 as a load cell a hydro-dynamic load cell may be used (not shown).
