摘要： 938,791. Fork lift trucks. YALE & TOWNE MANUFACTURING CO. Feb. 14, 1962 [March 2, 1961], No. 5618/62. Class 78 (3). The gripping arms 16, 17, Fig. 1, of a lifting truck are movable in unison transversely of the truck as well as in the normal load-engaging manner and to prevent the truck overturning, due to a load being lifted towards the extreme lateral positions of the arms, sensing means are provided which detect lateral movement of the centre point between the arms 16, 17 and operate control and indicating means when a limiting position is reached. The arms 16, 17 are moved by hydraulic rams 26, 27 controlled by the circuit shown in Fig. 10. The sensing means include a cam 33, Figs. 1, 10, which is moved laterally by the arms 16, 17 so that at extreme positions either one or other of ball and check valves 29, 30 are allowed to close by either a rod 36 and pivoted arm 34 or rod 37 and arm 35 as either wheel 68 or 69 runs off the end of the cam 33. When either of valves 29 or 30 are closed further movement of the arms 16, 17 in the same direction is prevented. Movement of the arms 16, 17 is controlled by valves 39, 59, as described in U.S.A. Specification 2,795,346. In one embodiment the cam 33 is moved by rods 86, 93, Figs. 1, 6, which connect the gripping arms with the upper and lower runs of a chain 81, respectively. The chain 81 is supported on sprockets 82, 83 pivoted to a laterally slidable member 78 on which is mounted the cam 33. When the gripping arms move in opposite directions at the same speed the chain 81 merely runs round the sprockets and the cam is not moved. If the arms move in the same direction, or in opposite directions at different speeds, the slidable member 78 and the cam 33 are moved laterally. In a second embodiment, Fig. 11, the chain 81 is replaced by pinions 97 which are interconnected by pinions 98 and the rods 86, 93 are replaced by toothed racks 99, 100 which engage the pinions 97 to move a slider 74 and the cam 33 laterally. Fig. 12 shows a third embodiment in which a lazy-tongs linkage 101 provides the connection between the gripping arms and a slider 74 and the cam 33. In Fig. 13, a lever 106 is supported by cables 112, 114 attached to the gripping arms and to a plate 64. The lever 106 carries mercury switches 109, 110 and is urged downwards by a spring 111. Movement of the arms in opposite directions at the same speed moves the lever 106 up and down. Movement in the same direction tilts the lever, closes one of the mercury switches, and energizes one of solenoids 116, 117 to close one of the ball check valves. In addition one of horns 119, 121 is sounded and one of warning lights 118, 120 is lit. The other embodiments may also incorporate audible and visible signals by using limit switches.

摘要： 937,926. Hydraulically operated door closers. YALE & TOWNE MANUFACTURING CO. Aug. 20, 1962 [Aug. 30, 1961], No. 31836/62. Class 65 (1). An hydraulically operated door closer comprises a casing 10 containing a cylindrical checking chamber 18 and a cylindrical spring chamber 17 at right-angles to it, an axially mounted crank-shaft 14 in chamber 17 whose square end 30 engages a star-shaped opening 52 in the closer arm 13 attached through adjustable link 15 to a bracket 16 on door frame F, a pin 27 of crank portion 26 of shaft 14 coacting with the bearing 40 of upwardly off-set connecting- rod 38 attached through wrist pin 46 to checking piston 47 so that rotation of shaft 14 against spiral spring 34 joining it to casing 10 is translated into axial motion of the piston 47. As the door closes the piston forces fluid through ports 48 past control valve 49; valve 50 allows free flow through the piston as the door opens. Cover-plate 19 may be removed to give access to cotter pin 27 detachably securing the forked end of rod 38 to crank pin 27. 0-rings 32 in grooves 33 on the crank-shaft prevent fluid seepage.

摘要： 933,303. Controllers. YALE & TOWNE MANUFACTURING CO. March 8, 1962 [April 11, 1961], No. 8906/62. Class 38 (3). An electrically operated industrial truck has an electrical traction motor 20 and includes a fluid pressure operable braking unit 24 and a fluid pressure operable speed control unit 25 which are connected by flexible conduits 27, 28, respectively, to a master cylinder 26 whereby operation of the master cylinder supplies fluid pressure to both said units to first release the brake and then operate the controller. When the master cylinder is released, the controller is returned to neutral position and the brake then applied. The piston of the braking unit 24 is urged by a spring in a direction to apply the brake shoes 39, 40 to a brake drum 22. The piston of the speed control unit 25 operates a control rod 53 to actuate in sequence a plurality of switches 52 to vary the motor speed, the piston being spring-urged in the neutral direction of the controller. Depression of a spring- biased pedal 29 operates the master cylinder 26 via rod 30, bell-crank lever 31 and cylinder rod 32. When fluid pressure reaches controller unit 25 to release the control rod 53, springs 54 move the rod toward high speed position under the control of a dashpot 57.
