IPC: B66B1/06
Filed: 1955-01-18
Abstract: 778,965. Control of D.C. motors. HALL, Ltd., J. & E. Nov. 7, 1955 [Jan. 18, 1955], No. 1548/55. Class 38(3) A lift-car is driven by mechanicallycoupled D.C. motors AH, AR, the motor AH having the greater torque. To start the car, a main control switch CS is actuated to connect the armatures of the motors in series and to energize the starting series field winding SRH of the motor AH, the field windings SHH and SHR of the motors AH, AR, being also excited. To increase the speed of the car, the armature of the motor AR is short-circuited to increase the voltage applied to the armature of the motor AH. Contacts RH1-RH4 are successively closed to reduce resistance RS and finally to short-circuit the field winding SRH. When the switch CS is again adjusted to the low-speed position, the armatures are re-connected in series and the field winding SHR is strengthened, the motor AR exerting a braking effect upon the motor AH. Operation in the reverse direction is prevented until the car 'has been stopped. The motors may be disconnected from the main supply source MS and connected to an auxiliary source ES. In this event, the motors can only drive the car slowly irrespective of the position of the main control switch, the braking resistance RB being open-circuited. When the car is being driven at a high speed by the motor AH, opening of either of the limit switches US or DS brings the motor AR into operation to decelerate the car. Opening of limit switches UL, DL, causes the car to stop.

Title: Improvements in power steering mechanisms for motor vehicles
IPC: B62D5/02
Filed: 1954-01-20
Abstract: 746,684. Steering vehicles. GENERAL MOTORS CORPORATION. Jan. 20, 1954 [March 17, 1953; April 29, 1953], No. 1707/54. Class 79 (5). In a motor vehicle power-steering mechanism rotation of the steering shaft 44 by a manuallyapplied torque exceeding a predetermined value effects engagement of one or other of two clutches 70, 72, whereby a shaft 50 is power rotated in one or other direction, the driver members of the clutches being continuously driven in opposite directions from the vehicle engine 15 through a free-wheel device 26. As shown in Figs. 1 and 3, the power steering mechanism 10 mounted on the vehicle frame 12 is supplied with engine power through a belt 18 off the engine crankshaft, the belt being connected to a shaft 24, connected by means of the device 26 to a shaft 28 carrying a pinion meshing with a gear 36. The device 26 permits relative movement between the shafts 24, 28 when the vehicle engine is not running. The gear 36 meshes with a gear 42, the gears 36, 42 being thus driven in opposite directions. The gears 36, 42 continuously drive the driver elements of the clutches 70, 72, the driven elements of which engage the shaft 50 carrying a ball nut 52 meshing with a gear sector 58 carrying the output arm 60 of the steering gear. The steering shaft 44 is axially fixed relatively to the shaft 50 by a with one of the clutches 70, 72. The shaft 44 and a sleeve 49 forming an extension of the shaft 50 are restrained against axial movement by spring-urged balls 54 engaging a groove in the end portion of the shaft 44. The shaft 44 is also connected to the sleeve 49 by balls 61 running in helical grooves 62 in the shaft and sleeve, a recirculator passage 65 being provided to permit the transfer of balls from one end to the other of the helical grooves. When the effort of the steering wheel rim exceeds two to eight pounds, the balls 54 yield to permit relative axial movement between the shaft 44 and sleeve 49, thus causing engagement of one of the clutches 70, 72. Leaf-springs 81 are provided in the clutches to prevent overloading of the clutches when the steerable wheels have reached their stops or when steering resistance is extreme. The normal tendency of the steerable wheels to assume their straight ahead positions is retained.

Filed: 1956-01-19
Abstract: 789,918. Oil dispensing cabinets. McCOWAN, D. A. Jan. 19, 1956, No. 1879/56. Class 116 An oil can display stand comprising end wall 2, 3 and can racks 4 has a can draining means mounted in its front wall 2 and comprising a closable can-receiving opening 25, a can-supporting trough 28 disposed behind the wall and inclined upwardly away from the wall to deliver the oil at its front end, and a receptacle 32 adapted to receive the liquid from the trough. A sliding door 26 acts by gravity to close the opening after a can has been inserted, the door having a lower curved projection 27 for raising it to permit entry of a cam. A spring member 29 holds an inserted can in position on the trough 28. In use, a can-opener 34 is removed from one of two containers 33 formed as recesses in the wall 2, and is inserted into a can. The door 26 is then opened by engaging the can with the projection 27, the can being carried by the can-opener held in the hand. As the door becomes partly opened the can is pushed through the opening 25, the door dropping down in front of the can until it rests on the opener. The opener is then withdrawn so that the oil drains from the can, via the trough 28 and a shoot 31 into the receptacle 32. The receptacle 32 may then be withdrawn by pulling out a sliding drawer 19 in which the receptacle is held by a clip 32a. When a further can is inserted through the opening 25 it pushes the previously emptied can off the rear end of the trough 28 into a compartment within the drawer 19. After use, the can opener 34 is re-inserted into one of the two containers 33 which slope downwardly towards each other behind the wall 2 and drain into the shoot 31. The display stand also includes twin paper towel dispensers comprising rolls 35 on which rests a plate 40 to produce friction. After use, the towels are pushed through a slot 21 in the wall 3 which is covered by a hinged flap 22, and drop into the empty-can compartment of the drawer 19. A pocket 6 is provided at each end of the towel dispenser for windshield cleaning fluid containers 7. The can racks 4 may be of either of two forms. In one form, Figs. 3 and 5, they comprise members 8 of S-section and backing plates 9. The cans rest on the flat portions 13 of the members 8 between the backing plates 9 and front ledges 16 of the members 8, whilst they are prevented from tipping out of the racks by the downward extensions 10 of the members 8 above. In the second form, Fig. 7, flat bars 17 are provided with rectangular notches 18a of a width less than the diameter of the cans, so that the cans rest in the bottoms of the notches, are held between the notches and the backing plates, and are prevented from tilting by the lower edges of the bars 17 above. The stand is provided with a pair of wheels 23 by which it can be moved about.

Title: Improvements in or relating to carrier current signalling systems
IPC: H04J1/06
Filed: 1931-01-20
Abstract: 371,369. Modulating circuits employing low-pressure apparatus. ASSOCIATED TELEPHONE & TELEGRAPH CO., 1033, West Van Buren Street, Chicago, U.S.A. Jan. 20, 1931, No. 1902. Convention date, Jan. 23, 1930. [Class 40 (v).] A pair of neon tube oscillation generators are caused to operate at a common frequency by including a resistance in the common branch of the two circuits ; and the oscillations are modulated in amplitude for carrier wave signalling by causing the signal to act differentially either on the supply voltage or on the capacities in the respective circuits. As shown in Fig. 1, one circuit comprises a neon tube 5 shunted by a variable capacity 7 ; resistances 9, 12; a transformer secondary coil 13 ; and a battery 11. The circuit of the second tube 6 is similarly arranged, except that the battery 11 tends to send current through the common branch 12, 13 in the opposite direction. Initially the condensers 7, 8 are adjusted so that although the circuits if isolated would oscillate at different frequencies, they are compelled by their coupling to oscillate at an intermediate frequency. Speech currents applied to the transformer 13 by a microphone 15 then cause variations in amplitude without affecting frequency. The modulated carrier wave is tapped off across resistance 12, and is amplified by valves 16, 23 and applied through a balanced transformer to the line 1, 2. A grid-leak detector 36 is also associated with the balanced transformer for reception. In a modification shown in Fig. 2, a differential electrostatic microphone 61 produces the modulation by acting differentially on the capacities across the neon tubes 50, 51. When applied to carrier current telegraphy, tone frequency oscillations generated by a third neon-tube are applied to and withdrawn from the transformer 13 by operating a signal key. At the receiving end, the rectified carrier wave vibrates a reed tuned to the tone frequency and thus opens the circuit of a relay which controls a sounder.

[Class 143] In a weighing scale having a check link 43 situated vertically below the fulcra 19, 23 of the beam 16 and pan-support 27, the pivotal connections at the ends of the check link each comprise a gravitationally engaged conical section extending through a circular knifeedged aperture. The depending leg 27 of the pan-support carries a bent plate 36 connected to the link 43 by a pin 37, Fig. 4, having a conical shoulder 41 on which the end of the link rests by means of a knife-edged orifice 42 in the link. A similar support 47 for the opposite end of the link is provided in connection with a bar 48 secured to the casing. The supporting end of the bar 48 may be adjusted vertically by a screw 49 to adjust the parallelism of the linkage. The scale beam 16 carrying an adjustable poise weight 52 is connected to a pointer 73 indicating subdivisions of the graduations 50 on the beam. The movement of the pointer is restrained by a pendulum 75 slightly off-set from the vertical when the pointer is at zero in order to take up slack in the connections. The tip of the indicator extends through a slot in the top of the casing and registers with graduations on sloping portions 61 which protect the pointer from injury. The beam is of hollow formation and its knife-edges 19, 23 are retained in the side walls of the structure by means of a clamping plate 24. An adjusting weight is provided inside the beam.

In a synchronizing arrangement for a free piston compressor comprising pistons which work in opposite directions in a combustion cylinder and whose rear ends also serve as compressor pistons each compressor piston 14 has secured to it at least one guide rod 15 which is directed towards the other piston is hollow at its free end and is mounted so as to be longitudinally slidable over a member 18 secured to part of the engine housing and is connected to the corresponding guide rod of the other piston by means of a rocking lever 28 acting on the free ends of the two rods as shown with the cavity 20 in the rod 15 the member or pin 18 forms a pump device. In the example illustrated it serves to feed oil vapour to the compressor piston 14 for the lubrication of the latter. The pumping action of the rod 15 and its guiding means may alternatively be utilized for the high compression of air for example for engine-starting purposes. In this case suction and delivery valves will be necessary. These valves and the corresponding ports may be provided, for example in the pin 18 or in the guide rod 15 itself. Thus the suction valve may be provided in the rod 15 at the end 26 of the cavity 20 and the delivery valve at the end face 27 of the pin 18. The rocking lever 28 is mounted in such a manner at least on one side that the injection nozzle (not shown) or other device or devices can be accommodated within the mounting.

Abstract: 538,633. Free - wheel clutches. CLARK EQUIPMENT CO. Jan. 31, 1940, No. 1942. Convention date, Feb. 17, 1939. [Class 80 (ii)] [Also in Group XXXI] Relates to a vehicle of the kind described in Specification 539,701 in which the vehicle is propelled by a main engine and an auxiliary engine which is automatically started and brought into action when the load and speed conditions are such that the main engine cannot deal satisfactorily with them. In the present arrangement the auxiliary engine is adapted to be connected to the propelling mechanisms by an automatic one-way clutch 29, and is provided with a control system such that when the vehicle speed lies between (say) 20 and 35 miles per hour and the main engine throttle is wide open the auxiliary engine is started and the clutch 29 automatically connects it to the driving gear so that it assists in driving the vehicle. A universal joint 30 is coupled to a stub shaft 52, having a steep-pitch screw thread 68 engaged by a clutch member 67, provided with ratchet teeth 66 adapted to engage similar teeth 65, on a sleeve 63 fixed to the auxiliary engine flywheel 62. The sleeve 63 carries a brake member 70 which engages the outer surface of the clutch member 67, so that when the shaft 52 is driven by the main engine but the auxiliary engine shaft is stopped this brake causes the clutch member 67 to stay in the disengaged position shown abutting a thrust collar 74. However, when the auxiliary engine is started up and speeds up until it rotates faster than the shaft 52 the brake 10 causes the clutch member 67 to unscrew along with the shaft 52, until the clutch teeth 65, 66 engage, and the auxiliary engine then assists the main engine.
