Title: Improvements in or relating to contacts for circuit breakers, switches and the like
IPC: H01H1/50
Filed: 1931-11-24
Abstract: 386,090. Switch contacts. FLURSCHEIM, C. H., Rushmoor, Fleet, Hampshire, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. Nov. 24, 1931, No. 32588. [Class 38 (v).] Oil-switches.-In switches of the kind in which the co-operating contacts comprise a pair of switch jaws and a co-operating switch blade two stationary jaws of calliper formation are bridged by a contact member carried by a relatively moving structure and comprising a pair of parallel blades each adapted to bridge the stationary contacts, the said blades being forced into high pressure with the co-operating jaws when in position therein by a toggle reaction between them. As shown in a singlephase double-break oil circuit breaker the stationary contacts 1, 1<1> comprise rigid jaws while the moving contact assembly comprises a cross frame 4 having insulated draw rods 3 and provided with upper, lower, and inner stops 5, 6, 7 for the current-carrying straps 8 which are connected to the cross frame 4 by toggle levers 10, 10<1> and by springs 9 which urge the straps into contact with the upper and inner stops 5, 7. On upward movement of the moving contact assembly the straps 8 enter freely the jaws of the stationary contacts 1, 1<1> and are stopped thereby, Continued upward movement of the cross frame 4 causes the straps 8 to be forced outwardly by the toggle levers 10, 10<1> into high pressure contact with the rigid jaws of the stationary contacts 1, 1<1>. The toggle levers each comprise two straps 13, 14 connected together at their ends with inserted distance pieces causing the toggles to be somewhat resilient at the centre opposite their pivots 17, 18.

Title: Improvements relating to the control of electric motors
IPC: B60L15/04
Filed: 1935-11-25
Abstract: 455,826. Field control of motors. WHYMAN, F., Arncott, Greenway Road, Timperley, Cheshire, and METROPOLITAN VICKERS ELECTRICAL CO., Ltd., 1, Kingsway, London. Nov. 25, 1935, No. 32678. [Class 38 (iii)] To reduce the field strength of a motor a section l, m, of the field winding is shunted through contacts S and nor mally closed contacts F in the circuit of the section l, m, are subsequently opened. The contacts S are closed by energization of an operating coil SO, Fig. 2, and the contacts F opened by energization of a coil FO, the circuit of the coil FO including interlock contacts S1 associated with the contacts S and the circuit of the coil SO including interlock contacts F1 associated with the contacts F. When a control switch is closed, for example, when an accelerating controller is operated to cause a contact stud a to engage the controller contact c the coil SO is energized and the switch S closes. The interlock contacts S1 are thus closed and the coil FO energized to open the contacts F. The interlock contacts F are operated and transfer the circuit of the coil SO to any alternative source such as a controller contact stud b energized in operative positions of the controller. When the controller is turned back the coil FO is de-energized, to close the contacts F and de-energize the coil SO at the interlock contacts F1. Thus the switch S is reopened and the original connections restored.

Title: Improvements in and relating to timing devices
Inventor: TOLL CECIL ALBERT
IPC: G07F17/00
Filed: 1962-08-27
Abstract: 1,001,080. Prepayment meters. ALBERICE METERS Ltd. Aug. 21, 1963 [Aug. 27, 1962; April 4, 1963], Nos. 32787/62 and 13382/63. Heading G4V. In its application to a prepayment timecontrolled meter a screw-and-nut quantity mechanism controls a switch, relative axial motion between the spur wheel driving the nut and the spur wheel driving the screw causing operation of the switch and the axial motion being accelerated at the point of switch action. In Fig. 2 spur wheel 18 is mounted on a sleeve 20 rotating in a bearing in mounting-plate 11. Spur wheel 22 is mounted on a spindle 21 threaded into the sleeve 20. The threaded connection between spindle 21 and sleeve 20 has considerable backlash normally biased one way by a spring 24. Holes in the spur wheel 22 hold captive ball bearings 25, 26 which; when the end 23 of spindle 21 is at its furthest point of travel towards microswitch 30, 32; lie in conical recesses in the opposed face of spur wheel 18. When coin action rotates wheel 22 with wheel 18 held fast, the first part of its rotation drives the ball-bearings out of the conical recesses in wheel 18 and thereby displaces wheel 22 to the left as permitted by the backlash. The switch operates to connect the associated apparatus and a timing motor restores the quantity mechanism by rotating wheel 18. As the mechanism approaches normal, the ball bearings snap into the recesses on wheel 18 and provide a fast axial motion of spindle 21 to operate the switch. The ball-bearings are held at different radial positions. In the arrangement of Fig. 3 there is no significant backlash needed between the hollow screw 42 and the nut 41. Spur wheel 50 is mounted on a plain spindle 48 and drives the screw by means of a sliding pin connection which allows relative axial motion. A plate 45, carrying hemispherical projections matched by corresponding recesses in the opposed face of spur wheel 40, is locked for rotation by pins and can be displaced axially with wheel 50. A spring 52 holds the wheel 50 and plate 45 together and against the end of screw 42. When the screw is displaced by the coin mechanism 12 the projections are driven out of their recesses withdrawing the spindle 48 rapidly and holding it until the screw 42 catches up with the plate 45. On restoration the screw leaves the plate 45 behind together with spindle 48 until the projections match their recesses whereupon the spindle snaps forward to operate switch 30, 31.

Abstract: 951,794. Photograph camera shutters. FEINGERATEBAU OTTO SCHLUND G.m.b.H. Sept. 30, 1960 [Oct. 2, 1959], No. 33730/60. Heading G2A. A photographic pivoted blade shutter comprises a master member arranged to move in the same direction during both opening and closing movements of the blades, with a blade ring with which said member engages during the opening movement but not during the closing movement, and a pivoted lever to effect the closing movement of the blade ring under the action of the master member. The shutter shown in Fig. 1 comprises a blade ring 6 which, when rotated in opposite directions, opens and closes blades 5 in known manner. The ring 6 is initially held stationary by a projection on a release setting arm 44 engaging a lug on the ring, but when the ring is released a master member 14 is rotated by its driving spring 16 so that a lug 18 on it engages a pin 12 (which passes through a hole 10 in the ring 6) and rotates the ring to open the blades. The lug 18 then slips off pin 12 and rotates a lever 38,by engaging a pin 39 on it, so that an arm 41 thereon engages either pin 12 or a lug 9 on the ring 6 to rotate the ring and and close the blades. A return spring 42 on the lever 41 dampens the impact of member 14 with lever 38. A shutter speed control mechanism 24- 30 is provided for varying the shutter speed and is engageable with the master member 14 during the blade closing movement. For bulb exposures, the master member 14 and lever 44 are moved by pins 19, 36 and cams 20, 34 on which they bear respectively,so that they do not engage the ring 6 which is rotated solely by means of a lever 43 connected to it by means of a pin 46 and notch 45. In the modification shown in Fig. 5, the return spring 42 is omitted and the pin 39 on the lever engages an arcuate slot 52 in the member 14 dur ing the opening movement of the blades and a radial slot 53 during the closing movement of the blades. The arm 41 is provided with a resilient cap 54 to reduce the impact between arm 41 and lug 9. The pin 12 is provided with an oblique surface 13 and is axially resiliently mounted so that when the member 14 is set by being rotated in an anticlockwise direction, pin 19 moves pin 12 axially and does not, therefore, rotate the blade ring 6. In other embodiments (a) the member 14 and lever 38 have a toothed segment connection (b) the lever 38 opens the blades and the member 14 closes them.

Abstract: 397,732. Thermally-actuated valves. KAPPELER, R., 21, Ottostrasse, Z³rich, Switzerland. Dec. 1, 1932, No. 34067. [Class 135.] A thermally-actuated safety cut-off valve is normally held in the open position by a catch adapted to be released by an expanding rod coupled to the catch through a rack and pawl or one-way friction clutch, so that the catch is released immediately the rod starts to contract. The expanding rod 1 subject to the heat of a burner is anchored at one end to a fixed part and at the other to a lever 2 engaging at its free end with the shorter arm of a lever 3 loaded by a spring 5. The longer arm of the lever 3 is coupled by a link 21 to a rod 4 slidably mounted in a member 10 carried by a plate 22 pivoted to the catch 11. Mounted within the member 10 is a wedging member comprising a ball 6 carried by a part 7 itself supported by a box-shaped part 8 pivoted to the member 10. On opening the gas cock, the handle 15 engages a pin 14 on a disc 12 to rotate the disc and stress a spring 13, the disc being retained in this position by the catch 11 engaging a projection 16. The member 8 is acted upon by a spring 9 to press the member 7 in the direction to grip the rod 4 so that when the thermal rod cools the rod 4 and member 10 move together to release the catch. In the event of the clutch failing a rack on the lower part of the rod 4 co-operates with a pawl 23 to release the catch. The pawl and rack arrangement may be used without the friction coupling. As the pin 16 and cock move to the closed position the pin 16 engages one end of a lever 17 causing the other end of the lever to engage a pin 26 on the member 8 moving it against the action of the spring 9 to release the friction clutch and remove the pawl from engagement with the rack.
