Title: Snap action electric switches
Inventor: LOWE SIDNEY ROLAND
IPC: H01H5/06
Filed: 1954-02-26
Abstract: 760,970. Thermal switches. MIDLAND ELECTRIC MANUFACTURING CO., Ltd. Feb. 24, 1955 [Feb. 26, 1954], No. 5691/54. Class 38(5) A thermal snap action switch which is adapted so that the contacts may be reset automatically or manually includes a manually operated bar 25 which may move downwards in a recess 24 and which has two positions of rest, one at the top as shown in Fig. 1 and one midway down. A bimetallic strip 21 heated by an element 19 carries an operating piece 22. A toggle mechanism comprises an actuating member 11, a contact carrying member 10 (both pivoted on the member 8), and an overcentre spring 16. When the piece 22 moves to the left the member 11 turns anticlockwise and causes the member 10 to snap over to the right moving through the member 11, thereby opening the contacts. The member 11 returns to its original position under the action of spring 15 as the bimetal cools, but with the bar in its top position (as shown), the dead-centre line is not reached and the contacts remain set open. Movement of the bar downwards causes its sloping face to engage the projection 18 whereupon the member 10 snaps, back and closes the contacts. If however the bar 25 is initially set in its mid position, when the switch opens the projection 18 engages the bar and prevents the member 10 moving quite so far to the right, whereup as the bimetal cools and the member 11 returns to its original position the dead centre line is reached and the member 10 snaps back to close the contacts automatically. The contacts may also be opened by hand when the switch is closed by moving the bar. right down so that it engages the projection 17 on the member 11; the contacts closing again immediately on release. Figs. 4, 5 and 6 (not shown), show a plurality of similar switches in a bank, and also describe means for setting the bar 25 in its two positions.
Patent GB-287551-A (GB)
Title: Improved automatic change speed gear
IPC: F16D43/06
Filed: 1928-02-23
Abstract: 287,551. Servon, J. L. March 25, 1927, [Convention date]. Variable-speed epicyclic gearing is controlled jointly by a governor 56 carried by the driving- shaft 4 and by a governor 30 and torque-responsive screw 18 upon the driven shaft. 2. Low and middle speed are brought in by arresting sun gears 10<2>, 10' by holding brake discs 11<2>, 11<1> respectively. This arresting is effected in part by the governor 56 which turns an eccentric 62 pivoted at 63 so as to press down a cam bar 38<2>. Swells 39 on the cam bar tilt a double-lobe cam 37 which engages the brake discs. The governor 56 thus connects and disconnects the drive. Selection of the speed is effected by the sliding of the cam lever 38<2> which is done by the governor 56 and 30 and the yielding screw coupling 18 jointly. The sliding of the bar 38<2> is rendered stepped in character by a spring thrust coupling 40 and a spring lock 41. Direct driving is effected when the governor 30 thrusts a grip shoe 33 into engagement with casing 1, which is fast on the driving-shaft 4 along with a boss 58 supporting the governor 56. The casing 1 carries planet spindles 7 to each of which are secured gears 8<1>, 8<2>, and 9<1> meshing respectively with the sun gears 10<1>, 10<2> and with a forward-driving sun gear 12' fast on a sleeve 12 which can rotate loosely between thrust collars on a smooth extension 19 of steep-pitched screwed sleeve 18. The sleeve 18 is slidably feathered on the driven shaft 2 and engages a notch 23 which has a feathered connection 25 with the gear sleeve 12. The gear sleeve 12 carries pivotally the clutch shoe 33 and the governor 30. A heel 32 on the governor lever bears against a thrust bearing 26 carried by the nut 23. Thus the torque in the shaft 2 acting through the screw against a spring 70 and against the governor 30 revolving with the same shaft serves to control the clutch 33, and through a lever 46 to operate an end section 38<1> of the speed selector bar 38<2>. The main part 38<2> of the selector bar is acted on also through a spring 48 by the governor 56. Alternatively, a hand lever 66 may tilt the double cam 37 to bring in the lower speed. Reversed driving is effected by sliding the sleeve 12 bodily to the right to bring a smaller sun gear 12<2> into mesh with a fourth planet gear 9<2>. This is done by manual means through a grooved striker 22. Alternative hydraulic means is described for connecting the three automatic control devices to the selector cam bar.
