Title: Improvements in and relating to variable speed powertransmission mechanism
IPC: F16H15/12
Filed: 1925-05-07
Abstract: 235,535. Hayes, F. A. June 12, 1924, [Convention date]. Variable-speed friction gearing comprises a roller 14, Fig. 1, which, in order to change the speed-ratio, is moved out of the line of centres 13, 12 of two face discs 10, 11 which the roller connects. The roller then moves parallel to that line of centres, and so the effort for the change of speed is supplied by the engine. The shaft 15, Figs. 5 and 6, carrying the roller 14 is supported at its end so as to permit such shaft ends to move in opposite directions. The shaft 15 is supported in a movable yoke 35 in inclined slots 39 to permit such canting of the shaft to assist the automatic change. The Specification as open to inspection under Sect. 91 (3) (a) comprises also an arrangement dcesribed with reference to the cancelled figures 5, 6, and 7 in which a pair of rollers 14 are employed without such opposite movement of the shaft ends. The rollers 14 connect a driving disc 10 to a pair of driven discs 11, 20, between which they are pressed by a spring 23. The rollers 14 are supported on a frame 15 which can turn through a small angle about a pivot shaft 22. When the speed is to be changed, a lever 30 is moved to stress a spring 29. The rollers being out of the line of centres move axially until brought back to that line against the tension of the spring 29 by the change of reaction of the driven discs. The shaft 13 of the disc 10 may be driven from a shaft 16 in line with the shaft 12 of the discs 11, 20 and provision may be made for bringing in automatically a direct drive between the shafts 16, 12. A clutch member 41 pressed by a spring 44 is kept from engaging a member 40 on the disc 20 by a trigger lever 45. When the rollers 14 move close enough to the shaft 12, they strike the lever 45, allowing the clutch 41 to act. This subject-matter does not appear in the Specification as accepted.

Abstract: 596,246. Supplying liquid fuel. TILLIET, J. E. May 16, 1945, No. 12304. Convention date, Feb. 7, 1944. [A Specification was laid open to inspection under Sect. 91 of the Acts, May 16, 1945] [Classes 7 (iii) and 7 (vi)] A fuel feed device comprises a rotating member connected with the timing gear of the engine which puts an orifice, fed with fuel under pressure, into, communication with an injection nozzle, the fuel being returned to the suction side of the pump during the remainder of the cycle. The pump 6 supplies fuel to a cylindrical sleeve 8 containing two orifices 5, 5a co-operating with orifices 10, 10a in a double walled sleeve 9, 19, a sleeve 11 connected to a disc 26 and carrying a nozzle 12 rotating continuously to allow fuel to be injected into a nozzle 13 whenever nozzle 12 passes the orifice 5. A cam 23, Fig. 2, on a shaft 24, connected to the throttle lever moves the sleeve 9, 19 through a push rod 22 and finger 20 to adjust the relative size of orifices 5, 5a, the total area of flow through these orifices remaining constant. The fuel flowing through both orifices is returned through sleeve 11 and pipe 15 to the fuel tank 7 except at the instant when nozzle 12 passes orifice 5. The throttle valve comprises a streamlined body 31 and a sliding Venturi 32 which is connected by levers 33, 40 to shaft 24 so that a constant fuel-air ratio is maintained: A spring loaded piston 36 subjected to fuel pressure by the pipe 35 corrects this movement for variation in fuel pressure. The sleeve 11 may be rotated by gears from the crankshaft, or from the rocker arm 4 of the inlet valve 2, by means of an adjustably connected arm 30 carrying a crank pin 29 flexibly connected to a pin 27 on the disc 26. The sleeve 11 may carry two nozzles suitably spaced apart supplying the injection nozzles of two adjacent cylinders. The Specification as open to inspection under Sect. 91 comprises also a modification in which fuel is supplied to a sleeve 8, Figs. 6 and 7 (Cancelled). fitted with orifices 5, 5a over which is fitted a sleeve 9 having orifices 10. 10a axially slidable bv means. of a finger 20a connected to the throttle lever, the injection of the fuel being timed by a reciprocating sleeve 11<0> having an orifice 12<0> co-operating with the orifice 5, 10.

Title: Improvements in mechanism for retarding tubs or trucks running down an inclined railtrack
Inventor: FRYE COLIN MICHAEL
IPC: B61K7/22
Filed: 1954-04-28
Abstract: 781,977. Axle stops. DOWTY HYDRAULIC UNITS, Ltd. April 28, 1955 [April 28, 1954], No. 12341/54. Class 103 (1). A structure for arresting tubs or trucks is secured between the rails of the track and has mounted thereon an arrester hook which normally projects into the path of and is maintained in engagement with, the axle or other part of the tub for a predetermined travel, an hydraulic dashpot for the hook resisting forward tub movement when engaged by the hook and a spring returning the hook to the initial tub engaging position after it has disengaged a tub. A roller 29, mounted on a pin 28 between the hooks 21, engages a platform 30 having an inclined ramp 31 at its forward end down which the roller 29 runs to move the hooks out of engagement with a tub axle. The platform 30 is longitudinally adjustable by means of a jack. The hooks 21 are pivotally attached by arms 22 to a block 17 mounted on a cylinder 11. The cylinder 11 is slidably mounted on a piston rod 10 attached between the plates 9, 9a and is closed at its rear end by a cap 12 and at its forward end by a cap 13. A flanged collar 14 mounted on the rear end of the cylinder 11 has a flange 15 which bears against a rubber buffer 16 abutting the block 17. A spring 25 is interposed between the plate 18 and the flange 26 of a collar 24 mounted on the cylinder 11 and bearing against the collar 13. The piston rod 10, Fig. 4, is hollow and has fixed thereon a piston 40, provided with holes 51, and has slidably mounted thereon a clock valve 52 provided with orifices 54 of a diameter smaller than that of the holes 51. The piston 40 is also by-passed by bores 55, 56, 57 and 58 in the piston rod 10. The bores 57, 58 may be adjusted to the fully open, closed or any intermediate position by a plunger 59 slidably adjustable within the rod 10 by nuts 61, 62. A bleed screw 65 is fitted in the cap 12 and a non-return oil charging valve 64 is provided in the end of the plunger 59. When a tub engages the hooks 21 the hooks 21 are moved from the left to the right of the Figure to compress a return spring 38 between the plate 18 and the plate 9a and the spring 25 between the plate 18 and the flange 26 in order. The spring 25 moves the cylinder 11 along the rod 10 against the pressure created in the cylinder by the oil passing through the orifices 55, 56, 57, 58, 51 and 54. At the end of the movement the roller 29 runs down the ramp 31 to disengage the tub and the hooks 21 and the spring 38 returns the apparatus to its initial tubengaging position. When the cylinder 11 is arrested at the end of its return stroke, the cup 12 engages a washer 44 and the impact of the hooks 21, plate 18 and block 17 is cushioned by the rubber buffer 16. The ramp 31 is moved to the position 31<SP>11</SP> when the device is to bo rendered inoperative.
