Patent GB-105659-A (GB)
IPC: B66B19/06
Abstract: 105,659. Sterling Telephone & Electric Co., Bell, F. G., and Davey, W. C. May 31, 1916. Mine signalling systems wherein the previous signal is cancelled on starting the engine by breaking the connexion between source of supply and the line, the connexion being immediately remade to enable further signals to be given during the running of the engine. Two relays are used; the first breaks the connexion to line and also completes the circuit of the second, which re-establishes the line connexion. When the engine stops, the first relay is de-energized and its armature restores the original contact to line, before the second relay, which is differentially wound, releases its armature. Thus signals given during the running of the engine are not cancelled by stcppage of the engine. A governor 12, preferably of gramophone type, driven by the engine, controls spring contacts 16, 17, 18. Normally, the positive pole of the supply is connected to line 21 through one armature a<2> of the first relay R<1> as shown. On starting the engine, contact 16 is allowed to break contact with the contact 17 and make contact with contact 18, closing the circuit of the relay R<1>. Armature a<2> thus breaks connexion to line, and armature a' completes the circuit of one winding w<1> of the second relay R<2>. The positive pole is thus connected to line through leads 19, 24, and armature a<4>, and at the same time a hold-on circuit for the winding w<1> is completed through the armature a<3>. Armature a<5> prepares the circuit of the differential winding w<2> of the relay R<2>, but this circuit remains broken at 16, 17. When the engine stops, contact is broken at 16, 18, and armatures a<1>, a<2> return to the position shown. Immediately afterwards, the circuit of winding w<2> is completed at 16, 17 and the armatures a', a<4>, a<5> are released. The desired governor speed may be obtained bv suitable gearing, and a slip ping clutch may be used if necessary to reduce excessive speed. The governor device may be replaced by any suitable means for controlling contacts 16, 17, 18, such as a known form of V-joint operated by the engine, or the contacts may be formed as the armatures of an electro-magnet, energized from a small dynamo-electric machine driven by the engine.

Filed: 1950-04-28
Abstract: 681,624. Feeding bottle caps. FARRER, J. O. (Waitkens. F., and Andrew, C., [trading as A. W. Machine Co.].) April 27, 1951. [April 28, 1950] No. 1057G/50. Class 78 (i). Relates to apparatus for sorting flat caps, i.e. caps having heights less than their diameters. The caps pass from a hopper 3 into a hollow rotatable member 7 which is keyed to a shaft 10 and the exit end of which is formed as a flange 19. The bottom 21, Figs. 4 and 5, of an annular groove 20 formed in the flange slopes inwards towards the periphery of the flange and forms a shoulder 22. A series of teeth 24 on disc 23 face the groove 20 and are shaped as shown in Fig. 3. The disc 23 is keyed to the shaft 10 and can be moved along it by turning a nut 26. Caps slide down the member 7 into the space between the flange 19 and disc 23. If orientated incorrectly the crown of the cap is presented to the teeth 24, Fig. 4, and the cap rests on the shoulder 22. The cap is carried around by the rotating parts until it reaches a position where it falls away from the shoulder and slides over the bottom 21 into the member 7. If a cap is orientated correctly its inside will be presented to the teeth 24 and it will slide off the tooth between the top and the sloping portion 21a, Fig. 5, of the groove into the space 35 and roll therealong to a delivery channel. A rotatable wheel 42 with peripheral irregularities extends into the delivery channel and agitates the caps to prevent jamming. Caps in the member 7 are agitated by plates 33 on the disc 23.
