Title: Improvements in or relating to Throttle Return Check Assemblies
Inventor: EMERSON JOHN RUSSEL
IPC: F02M3/06
Filed: 1966-06-08
Abstract: 1,150,657. Dashpots. F & E MANUFACTURING CO. 8 June, 1966, No. 25435/66. Heading F2S. In order to prevent stalling of an I.C. engine due to the abrupt closing of the carburetter throttle valve to the idle position while offering little hindrance to an'opening movement of the valve an air dashpot (10), Fig. 1, not shown, is secured to an engine (12) with an abutment screw (16) on the outer end of an actuating stem (46) in engagement with a part (18) of the throttle linkage. As shown, a flexible diaphragm 28, sandwiched between a pair of abutment discs 52, 54, has its outer edge clamped between the corresponding edges of a pair of dished circular covers 22, 24 of a housing 20 to divide the latter into two chambers 86, 88. The abutment disc 52 is urged toward the cover 24 by a compression spring 90 which is constrained between the abutment disc 54 and the cover 22, the latter having an opening 30 surrounded by a fitting 32 which has a neck 34 adapted to be connected, by a conduit, not shown, to the intake manifold of the I.C. engine. The inner edges of the diaphragm 28 and the abutment discs 52, 54 are carried on a head 55 at the inner end of the stem 46 which is slidably received in a bushing 38 which is made, e.g., of nylon and which is secured within an aperture 36 in the cover 24. The bushing 38 has a cone-shaped part 38 to facilitate insertion into the aperture 36 and circumferentially spaced, longitudinally extending, grooves 44 in its inner surface to provide communicating passages between the chamber 86 and the space within a flexible boot 60, which has a radially inwardly projecting flange 64 seated in a groove 66 in the stem 46. The other end 62 of the boot 60 is urged by a spring 70 into abutment with a coined ridge 56 on the outer face of the cover 24, a radial metering slot (58), Fig. 5, not shown, being provided in the ridge (56). The abutment screw 16 is threadedly adjustable in the stem 46 and can be held in position by a nylon insert 80 or by a lock-nut (146), Fig. 1, not shown. In operation, vacuum within the manifold of a predetermined minimum magnitude allows the atmospheric pressure in the chamber 86 to move the diaphragm 28 and the stem 46 towards the casing 22, the notch 58 restricting flow of air into the chamber 86 so that the throttle linkage can move toward the delay position with a predetermined time delay. If the throttle valve is suddenly moved to the fully open position the spring 90 rapidly moves the diaphragm 28 toward the cover 24 since any build-up of air pressure within the boot 60 is prevented by the end 62 of the latter lifting off the coined ridge 56.

Abstract: 1,088,603. Ink-ribbon mechanism. EXCHANGE TELEGRAPH CO. Ltd. July 1, 1966 [June 16, 1965], No. 25565/65. Heading B6F. Automatic ribbon reversal.-The ends of an ink-ribbon are secured to two spools X, Y and when one spool is completely unwound the resistance to the driving gear E, mounted on an arm L for engaging either gears A or B on the spool shafts, causes a synchronous motor to stall and a spring coupling to set the motor driving in the reverse direction. When the motor starts to drive in the other direction the driving gear E is forced to disengage from the previously driven gear to the other. The spring coupling (P), Fig. 2, firstly allows the motor to attain its synchronous speed against a reduced load and secondly it winds up as the ribbon tightens and, when the motor stalls, it provides a starting torque for the reverse drive. Brakes.-An adjustable collar (M) and helical spring maintains tension on the ribbon.
