摘要： 627,559. Fluid-pressure controlled brakes. GENERAL ELECTRIC CO., Ltd., and FOSTER, R. T., [Representative of FOSTER, H. H.]. Feb. 15, 1946, No. 4852. [Class 103 (i)] In a brake control system in which the brake is normally applied by fluid pressure acting on a first piston at one end of a slidable member connected to the brake, when the fluid pressure acting on a second piston at the other end of the member is reduced, the chamber of the first piston is directly connected to the pressure source and contains a third piston which carries a weight and is normally supported by the pressure fluid but which engages the slidable member to apply the brake if the fluid pressure fails. As shown, cylinders 8, 9 of pistons 6, 7 at the ends of a member 5 connected to a brake operating lever 2 are connected respectively to an oil pump 15 and to a control valve 21 which is also connected by pipe 19 to the pump. A pneumatic accumulator 27 provides a reserve of liquid under pressure. A piston 11 slidable in the cylinder 9 carries a weight 12 and is normally displaced from the piston 7 as shown by the fluid pressure a valve 16 being opened by the piston to byepass the pump when it reaches a predetermined height. A pressure relief valve of usual kind may replace the valve 16. The valve 21 is controlled by a manually operated floating lever 24 which is connected to the member 5 to give a follow-up action. Assuming the pistons to be in the raised position, downward movement of the lever 24 connects the cylinder 8 to the sump 17 through pipe 25 and a throttle valve 26, so that the member 5 descends under the pressure in cylinder 9 to apply the brake. When the lever 24 is raised the cylinder 8 is connected to the supply pipe 14 by the valve to release the brake. Should the oil pressure fail when the brake is off, the piston 11 moves downwards to abut on the member 5 so that upon subsequent operation of the valve 21 to vent the cylinder 8 the brake is applied by the weight 12. A hand or other pump may be arranged between the sump 17 and the lower end of the member 5 to enable the brake to be released when the main supply has failed. The pistons 6, 7 may be of equal areas, a reducing valve being arranged in the connection to the upper cylinder. The brake may be used for winding engines.

摘要： 556,354. Drop forging. FOSTER, H., and DONCASTER & SONS, Ltd., D. March 10, 1943, No. 3885. [Classes 83 (ii) and 83 (iv] A series of dies for use in the production of drop forgings are themselves produced by drop forging from a single pair of master dies, for each die part, aided, in the case of intricate forgings, by preparatory or breaking down dies. In cutting the master dies double contraction is allowed for. One die part a, Fig. 3, for the production of a rocker has the recess m surrounded by a parting surface k formed by a recess j sunk round the replica of the rocker part d in the master die b, Fig. 1. The die b pairs with a die c and these dies are formed at h to provide a narrow opening or vent for the escape of a limited amount of flash as determined by the capacity of the space g, and by this means flow of metal is maintained completely to fill the die cavity. The production of the other die part is similar.

摘要： 527,016. Winding hoists and the like. GENERAL ELECTRIC CO., Ltd., and FOSTER, H. H. Feb. 28, 1939, No. 6593. [Class 78 (v)] A multi-drum winder, hoist, &c. is provided with a plurality of brakes, the application of one or more of which is adapted to be delayed. The Figure shows three solenoids 1 which hold off the brake on the second drum, except in an emergency, and the circuit of which includes a contactor 2 arranged to be opened by the opening 'of a safety control means 3. Each solenoid 1 is energized by a phase of a three-phase supply 4. The second brake is held off by one or more solenoids 5 energized by a constant voltage direct current generator 6 driven by the winder shaft 7. In the circuit of the solenoid 5 is a time-delay contactor 8, which allows the second brake to come on a few seconds after the first brake, and is operated by the energization of the control 3. The contacts of the contactor 8 are shunted by a switch 9 having double contacts and operated by a deceleration governor 10, also connected to the winder shaft 7. The governor 10 causes closure of one or the other pair of these contacts of switch 9, according to the direction of rotation of the shaft 7, if the deceleration produced by the brakes is greater than a predetermined value, thus shorting the time-delay contacts 8. In an emergency the safety circuit thus operates contactors 2 and applies the first brake, and later on the second brake comes on. If, however, the deceleration is sufficiently great, the contacts 9 are operated and nullify the effect of opening the time-delay contacts 8. The second brake then comes into action just before the winder comes to rest. When two drums are employed clutched separately to the shaft 7 a contactor 11 may be provided in the circuit of solenoid 5 and be arranged to open when the clutch of the second drum is disengaged, thus being ready for immediate application when the clutch is re-engaged. Manually operated brakes are also provided, means being fitted to prevent application of the delayed action brake independently of the governor 10. Specifications 426,394 and 483,580 are referred to.

摘要： 126,749. Anderton, H. F., Bailey, G., and Robertshaw, W. July 8, 1918. F e e d i n g openers, carding- engines, &c.-In machines for preparing wool and like fibres, the sheet of fibres delivered bv one machine is transferred direct to the feed apron of the next machine and is laid thereon in folds bv a swinging frame 17 mounted in a fixed frame f. The fibres are delivered from the machine A bv rollers 2, 3 to endless aprons 8, 9 which pass round rollers 5, 10, 12, 11, and 6, 11, 14, 13 respectively. The frame 17 is pivoted at 16 on the frame f and is swung by cranks 22 over the feed apron 25 of the machine B. The sheet of material may be severed at the folds by a rod 27 carried by arms 28 and operated by stops 32 , 34 when the frame 17 comes to the ends of its path. The rollers 12, 14 may move in an horizontal path over the apron 25, runners on the rollers 12 engaging the edges of the trough 26. In this case, to enable the belts 8, 9 to preserve their tension, the rollers 10, 11, 13 are carried on the swinging frame.

摘要： 483,580. Winding-apparatus; brakes. GENERAL ELECTRIC CO., Ltd., FOSTER, H. H., and WHITMORE, F. L. Oct. 22, 1936, No. 28761. Addition to 426,394. [Class 78 (v)] [Also in Group XXXIV] The apparatus described in the parent Specification is modified in that: (1) an adjustable needle valve 9 is provided in an extension 6 of the valve 14, for connecting the pipe 4 to exhaust; (2) the differential gear constituting the governor comprises sun wheels 25, 25a mounted on shafts 24, 31 respectively, the shaft 31 being coupled to the winding shaft and to planet wheels 27, 28 carried by the flywheel 26; (3) the crank arms 15, 15a mounted on an extension of the shaft 24, are coupled by a pin- and-slot connection to links 16, 16a which are connected direct by the lever 17 to the operating rod 12 of the valve 14, and springs 18, 18a are provided in the slots in the links, said springs being initially loaded to transmit without deflection the force normally required to operate the valve 14. If the arms 15, 15a are rotated on account of a seized bearing in the differential, the valve 14 is moved to a position connecting the pipe 4 to the pressure supply to prevent application of the brakes, but by compressing the springs 18, 18a, the arms 15, 15a then move the valve in the opposite direction to restore control of the brakes to the driver and connect the pipe 4 to the exhaust via the valve 9 and so cause automatic application of the brakes. Should an exceptional overspeed occur such as might be caused by failure of the pilot valve 5 to operate the brakes, a governor on the drum shaft opens a switch whereby a clutch 29 locks the differential to effect rotation of the arms 15, 15a as above.
