Title: Improvements in and relating to governing mechanism for prime movers
IPC: G05D13/00
Filed: 1926-02-26
Abstract: 265,398. British Thomson-Houston Co., Ltd., (General Electric Co.). Feb. 26, 1926. Fluid governors; centrifugal governors. - A governor controlling a pilot valve which in turn controls a fluid operated motor has its setting adjusted by two members in threaded engagement one of which is frictionally held from turning whilst the other is rotated by a synchronizing motor, stops on the stationary member being engaged by a stop on the rotating member at either end of the travel so that thereafter the members rotate together. The arrangement as applied to a valve gear of the type described in Specification 229,325. The admission end 5 of a turbine is controlled by a valve such as is described in Specification 229,321, [Class 135, Valves &c.], and operated by a cam shaft 7. A pinion 11 on the cam shaft is in mesh with a rack 12 connected by a rod 13 with a spring- loaded piston 14 working in a casing 15. On the turbine shaft 8 is a worm 18 meshing with a worm wheel 19 on a vertical shaft 20 which drives an oil pump 22 in a tank 9. The oil from the tank is maintained at a definite pressure in a pipe 29 which is in communication with the cylinder 15 beneath the piston 14, as well as in a bye-pass 30 which conducts the oil back to the tank through ports 34, Fig. 2, and the inside of a pilot valve sleeve 73. The extent to which the ports are opened is controlled by a governor 85, which on an increase of speed lowers a sleeve 73 and opens the ports further. A decrease of pressure in the pipe 29 occurs, and the spring loaded piston 14 descends to close the valve 6 to decrease the supply of fluid to the turbine. Hunting of the valve mechanism is prevented by the closing movement of the cam shaft 7 operating a cam 66 which permits a linkage 58-61 to move to the left under the action of a spring 65. A bell crank lever 57 moves a sleeve. 50 and in turn a bushing 33, surrounding the valve sleeve 73 so as to close the ports somewhat. With decrease in the supply of fluid the turbine returns to normal speed. Decrease in the turbine speed causes operation to take. place in the opposite direction. The adjustment of the governor setting for different speeds is effected by changing the setting of the bushing 33 relatively to the valve sleeve 73, which is effected by means of a reversing synchronizing motor 71 controlled by the usual switch. The motor through the worm gear 43 turns a sleeve 44 either up or down and with the sleeve moves a keyed head 35 rigidly connected to the bushing 33. The head 35 screws on a frictionally held stud 38 which allows the head to work between upper and lower limits established by stops 39, 40 which are engaged at top and bottom by stops 41, 41a. When either pair of stops comes into engagement the vertical movement of the head 35 is arrested and if further operation of the motor takes place the stud turns with the head 35 and bushing 33 the friction hold of the stud slipping.

Filed: 1969-02-05
Abstract: 1292461 Valves TULLY ENG CO Ltd 2 Feb 1970 [5 Feb 1969] 6260/69 Heading F2V A valve, which is suitable for controlling the transfer of reject material from a pulverizing mill 2 and into a shoot 3, comprises a closure member 1, a pair of carriers 17 mounted on the shoot 3 through the intermediary of a plurality of pivotable links 18, a plurality of rollers 16 disposed within the carriers and acting to support the closire member 1, and a drive nut 11 which is coupled, on the one hand, to a screw 12 driven via a reduction gearing 15 by an electric motor 14 and, on the other hand, to two arms 10 each of which has its other end retained within an elongated slot formed in a bracket 9, each such bracket being carried by the closure member 1. In operation, closure of the valve is achieved by actuating motor 14, this driving screw 12 and hence moving closure member 1 along the rollers 16 until the closure member engages the terminal portion of carriers 17. Thereafter, the action of the screw 12 upon the drive nut 11 and hence upon the immovable closure member, causes the carriers to pivot as a result of which the closure member is brought against its seat 7. Subsequently, the drive nut is prevented from moving further and continued action of screw 12 causes it to shift against a plurality of Belleville washers (19, Fig. 5, not shown), until a micro-switch operates to stop the electric motor 14. When so stopped, the washers exert a thrust on the drive screw and so ensure firm seating of the closure member. To open the valve, the motor is simply operated in the reverse direction, the closure member being firstly moved in a direction substantially along the seat axis prior to being subjected to a lateral movement.
