Patent GB-853685-A (GB)
Title: Variable-speed transmission
Inventor: ENYEART DUANE BRUCE
IPC: F16H61/02
Filed: 1957-03-07
Abstract: 853,685. Variable-speed gearing. MONARCH MACHINE TOOL CO. March 7, 1957, No. 7601/57. Class 80 (2). In a variable-speed transmission, particularly for machine tools such as lathes, power means for shifting from one speed train to another are controlled by valve means having a number of positions corresponding to the different speed trains and being operated through the agency of a manually controlled fluid motor. The input shaft 19 of the transmission is driven from a motor 12 through a fluid operated clutch/brake device 16 under control of a manually operated valve 338 supplied by a pump 28. A plurality of fluid motors 97 operating shifter forks 22 of gears of the transmission indicated at 15 are controlled by a rotary selector valve 23 which has a number of positions corresponding to the different speeds obtainable. The rotatable element of valve 23 is coupled to the inner member 316 of a paddle motor 314 by a shaft 318, the outer member 312 of which is manually adjustable through a differential gear 261 by two separate control knobs 251, 252 in accordance with, for example, the work diameter and cutting speed on a lathe. The outer member 312 of the motor 314 has inlet ports 324, 326 and exhaust ports 320, 322 positioned so that as the outer member is moved the inner member 316 coupled to valve 23 performs a "follow-up" action. Thus different settings of the knobs 251, 252 determine the setting of valve 23 which is suitably indicated to energize the necessary motors 97 of the transmission 15 to give the desired speed ratio. The control valve 338 has three positions, "brake" in the centre as shown, "clutch" to the right and " shift " to the left. In the " clutch " and " brake " position the fluid pressure to selector valve motor 314 through line 358 is interrupted so that even if the knobs 251 and 252 are adjusted the valve 23 is not actuated and no shifting movement can occur until valve 338 is moved to the "shift" position. A " jog " mechanism 26 is provided to apply pulsating mechanical impulses through a freewheel clutch 232 and clutch discs 184, 185 to the input shaft 19 of the transmission if a selected gear is not properly positioned for engagement. This mechanism is brought into action by pressure drop in a line 105 supplied through a restriction 366 and controlled by a detent valve 106 which is opened to exhaust when the shift fork 22 is held in a central position through non-engagement of the gears. This " jog " action continues until the gears engage and valve 106 closes.

Abstract: 393,715. Automatic circuit-breakers. PAILIN, Ltd., F. and PAILIN, G., Buckley Street, Higher Openshaw, Manchester. March 15, 1932, No. 7641. [Class 38 (v).] The trip-catch or toggle of a circuit-breaker is operated to open the latter by means of a lever a on a shaft m which carries by means of a lever o a part p bearing on a plunger c. The latter is normally separated from an extension e of an abutment b by a quantity of gunpowder d located in a housing g which has apertures h adapted to be plugged by wax. The abutment b is removable and is held in position by having its pins i passed through slots in the plate k and by being turned through an angle. The circuit is from u to v by way of b, e, f, c, the member f being a fine wire which serves on overload to ignite the gunpowder d. The pressure on the latter is set up by a spring r and plunger s acting on an arm t on the shaft m, and when the powder ignites, additional pressure is exerted thereby on the part r<1>. If the normal current is excessive for the wire f it is heated by a current transformer connected in the circuit to be broken.

The beams 3, 5 of each frame are connected by telescopically adjustable beams 2, 4 and 6, 7. The upper wall 11 is suspended from cables 24 which pass over rollers 21, 22 and are connected to a counterweight 23 on the side of the framework opposite to a control panel 30. Vertical beams 26, 27 which are laterally displaceable have their lower ends positioned within the U-shaped crosssection of the beam 8 and their upper ends are provided with rollers 31 which roll in the similarly shaped beam 9. The side wall 13 is mounted on one of the beams 27 and its upper part is divided into a number of portions separated by rubber strips, the portions being inter-connected by a rubber or plastics mat. This construction enables the top of the wall to be folded over in order to adjust the height of the wall to correspond to the height of a test window, &c. The flexible upper portion of the wall includes a device for stiffening the wall. The rear wall 15 is coated with a layer 48 of tin plate to which a spray nozzle 51 is magnetically attached in any required position. To test a window and its frame 20, the movable walls are adjusted in position to correspond to the periphery of the window frame and a hydraulically operated pressure cylinder 17 is actuated to press the wall 11 against the wall 14. A similar pressure cylinder 18 presses the wall 11 against the movable wall 13, sealing surfaces being provided to ensure a seal between the walls. The beams 26 are then evenly spaced across the chamber opening and pressure cylinders 16, the positions of which are vertically adjustable, are actuated to seal the window frame to the chamber opening, sealing surfaces being provided on the edges of the chamber walls. Water from a line 52 is then sprayed into the chamber by the nozzle and collects in a trough 57.
