Title: Improvements in treadle controlled door
IPC: E05F15/10
Filed: 1927-08-03
Abstract: 275,629. National Pneumatic Co., (Assignees of Forman, P. R.). Aug. 3, 1926, [Convention date]. Operating doors electrically and pneumatically and by treadles.-In an automatic door-operating device in which the weight of a person passing through a doorway depresses a treadle and closes a switch so that an electric or pneumatic motor then opens and closes the door, the treadle plate is composed of a plurality of pivoted sections, the depression of any of these sections operating the switch. Depression of the treadle 63 causes a lever 65 on a shaft 66 to lift a spindle 67 against the action of a spring 68. This closes the contacts 73, 74, 75 and breaks the contacts 71, 72, 73 and causes a reversal of the current in the aramature circuit of the door motor 60, the doors then opening through the movement of a lever 61 connected to the spindle 53 on which the door 51 is mounted. The door 50 is hinged to the door 51 that is provided with rollers 56 that are slidable in guides 57. On the end of the door-opening movement the motor opens the switch 78, and closes the switch 77 ready for the closing movement. When the treadle is free to return to its normal position, the spring 68 moves the contact members on the spindle 67 to reverse the armature current and cause the doors to close. A pneumatic motor may be used instead of an electric motor. Fig. 8 shows how the sectioned treadle is mounted for operating the lever 45 that makes and breaks the switch contacts of the magnetic valve of the pneumaticmotor.

Title: Improvements in or relating to hydraulic remote control apparatus
IPC: F15B7/00
Filed: 1938-07-12
Abstract: 516,752. Hydraulic transmission with remote control. SPERRY PRODUCTS, INC. July 12, 1938, No. 20623. Convention date, July 31, 1937. [Class 69 (ii)] A balanced hydraulic remote control is arranged to maintain the parts in position after actuation and comprises a transmitter connected by a single column of liquid to a receiver and applying to the column a force which increases the further the operating means is actuated, the receiver offering increasing resistance substantially equal to the transmitter force. As shown, a lever 15, loaded by a spring 22, is pivoted at 17 and is so arranged that the force transmitted by an arm 18 to a piston rod 20 increases at a constant rate. The piston rod moves a piston 11 and thereby piston 11<1>, at the other end of liquid in a conduit C, is moved against the action of a spring 50. A valve stem 36 moves a valve 37 downwardly to open a port 38 to a source 39 of oil under pressure. The port leads to a propellor pitch control device to change the engine revolutions. As the engine " picks up " the valve closes the port to maintain the propeller pitch. For this purpose a governor 43 may be used. In a modification additional spring loading means may be employed for the piston 11<1> when it is desired to use a conduit C of such small bore that friction losses are relatively high. For periodically replenishing the liquid system trip mechanism 61 and reservoir 64 are employed as described in Specification 419,310.

Abstract: 716,223. Statistical apparatus. POWERS-SAMAS ACCOUNTING MACHINES, Ltd. April 28, 1953 [Aug. 21, 1952], No. 21063/52. Class 106 (1) Apparatus for feeding a record card to a sensing position and removing it rapidly therefrom after sensing against a card stop, comprises a pair of co-operating feed rollers to advance the card into sensing position placed so that when the leading edge of the card is arrested by the card stop, the trailing edge is freely located in the bight of the feed rollers, a pair of eject rollers located between the card stop and the feed rollers, a pivoted support for the freely rotatable feed roller, provided with light spring tension to bring the eject rollers together and pressure means to increase the pressure between the eject rollers (above the light spring pressure) whereby the card is firmly gripped between the eject rollers and is removed thereby from the sensing position. Cards are fed from the magazine 1, Fig. 2, by known means not shown to rollers 2, 3, and thence by feed rollers 4, 5, to the card stop 10. The upper roller 4 is freely rotatable and is pivoted at 11 on a bell crank lever 12 which is pivoted at 13 and urged towards the power driven roller 5 by a spring 15. When the sensing operation is complete and the card stop 10 is withdrawn the eject rollers become operative to remove the card rapidly from the sensing position. The eject rollers 8, 9 are mounted between the card stop 10 and the feed rollers 4, 5, the lower roller 9 is power driven and the upper roller 8 is freely rotatable on a bell crank lever 20 pivoted at 21 and urged towards the roller 9 by a light spring 23. When the card stop 10 is withdrawn in the usual manner, by means not shown, shaft 50 and the arm 49 are rocked tb allow the abutment 47 on the plate 46 to contact the bell crank 20 and since the spring 48 is stronger than spring 23 further pressure is applied to the eject rollers which were able to slip during the sensing operation, but under the increased pressure now applied, grip the card firmly and remove it from the sensing position, to rollers 56, 57, or other part of the apparatus receiving the card. The extra pressure is applied at the correct moment (synchronized with the withdrawal of the card stop) by means of a cam 55 mounted on shaft 42, Fig. 1. The cam follower 54 rocks the bell crank lever 52 which engages the lever 51 fast on the cross shaft 50 to rotate it and hence rotate the arm 49 bearing on the pressure plate 46 to render it effective. A further cam 41 on shaft 42 is effective through cam follower 40, lever 38, lever 37 and cross shaft 30 to close together a pair of lateral card alignment levers 24, 25, to align the card laterally whilst it is pressed against the card stop 10. The levers 24, 25, are withdrawn during passage of the card into and out of the sensing position.

Title: Improvements in the steering of vehicles
Inventor: BOWERS ERIC HIDER
IPC: B62D11/04
Filed: 1956-07-09
Abstract: 831,196. Motor vehicle hydraulic driving gear. DOWTY HYDRAULIC UNITS Ltd. July 8, 1957 [July 9, 1956], No. 21237/56. Class 79(2) In a vehicle with ground engaging elements such as wheels or endless tracks 2, Fig. 1, separately driven by independent hydraulic motors 6 the speed control members 19, 21 for each motor are interlinked so that they are moved in unison for normal speed control and moved oppositely for steering by differentially driving the tracks. In one example the motors 6 are supplied from two swash-plate pumps 9, 11 having variable outputs controlled by push rods 19, 21 of servo units 17, 18 attached to the pump bodies. The push rods 19, 21 are controlled from a gear lever 36 and steering wheel 37, the arrangement being such that when the gear lever 36 is moved to drive the vehicle in reverse by cross-wise movement in a slot 72 of a plate 69 the linkage automatically reverses the sense of the steering so that the vehicle moves in the same curved path according to the setting of the steering wheel as when moving in forward direction. The lever 36 is coupled through links 46, 47 to a pin 45 interconnecting a pair. of cross links 51, 52 attached by pivots 53, 54 to the push rods 19, 21. The cross-links 51, 52 are also pivoted at 41, 42 to a T- shaped member 38 which is pivoted at 39 to the vehicle frame and is swung about the pivot by the steering wheel 37 through the steering arm 65, push rods 63, 56 and an intermediate T-shaped lever 58 which is pivoted at 59 to the vehicle. A push rod 68 connects the gear lever 36 to the push rod 63 to move its end 62 from side to side in a slot 61 of the lever 58 to reverse its direction of rotation by the steering wheel 37 according to the sideways movement of the gear lever 36. In the hydraulic system for the control of the two motors 5, 6, Fig. 3, the supply for the servo units 17, 18 is taken from the supply lines through valve casings 24 containing opposed non-return valves 26, 27 so that the servo units are under pressure irrespective of in which direction the pumps are operating. A priming pump 28 is also incorporated in the circuit and supplies sufficient pressure through non- return valves 31, 32, 34, 35 to operate the servos when the gear lever is set at neutral and no pressure is supplied by the main pumps 9, 11. In a modification the gear lever 36, Fig. 2, operates the control rods 19, 21 through push rods 87, 88, interconnected links 101, 102 and crank arms 103,104 pivoted to the vehicle. A pin 89 interconnecting the links 88, 101, 102, engages a longitudinal slot 91 in a geared sector 94 rotatable by the steering wheel 37 through gears 95, 96. With this arrangement the opposed movements of the control rods 19, 21 by the steering wheels 37 is progressively increased with the speed of the vehicle as determined by the lever 36 so that the vehicle steers on the same curve irrespective of speed according to the setting of the steering wheel as in conventional steering.
