Patent GB-231227-A (GB)
Title: Improvements in electrical switches and operating mechanisms therefor
IPC: H01H19/24
Filed: 1923-12-21
Abstract: 231,227. Cox, F. B. Dec. 21, 1923. Controllers, actuating- mechanism for.-Relates to quick-action mechanism for step-by-step switches, controllers &c. in which a handle is turned to store up energy in a spring, so that when the switch shaft, which is held against the action of the spring by one of a pair of reversely set retaining pawls, is released by further movement of the handle, it is moved to the next position with a snap action. The fixed ratchet teeth are located on the side of the pawls remote from the centre of motion the arrangement being such that as a pawl after its release flies from one position to the next, its outward movement to engage the next tooth is assisted bv centrifugal force. As shown in Figs. 1-4, if the handle F which is loose upon the switch shaft A is moved in the direction of the arrow in Fig. 1 a projection f<1> on the handle boss engages a projection d<1> integral with the spring straining lever D<1> so straining a spring E<1> which connects it to an arm b<3> of a pawl carrier B secured on the switch shaft A. Two other arms b<1>, b<2> of the carrier B support pivoted pawls c<1>, c<2>, pressed apart by a blade spring c<3> the outer ends of the pawls carrying rollers c<2> engaging) the internal teeth of a fixed ratchet G. The switch shaft is thus held during the straining of the spring E<1> until the arm D<1> engages the tail c<5> of the pawl c<1> and so moving its roller c<2> clear of a ratchet tooth as shown in Fig. 2 so that the carrier B together with the shaft A is moved quickly across to the position shown in Fig. 3. The rapid movement of the carrier B with the pawls produces centrifugal action on the latter which assists their engagement with the ratchet teeth which are profiled at their apices as circular arcs centred at the pawl pivots to secure normal engagement of the pawl rollers. A similar action is produced if the handle is turned in the opposite direction to step round the switch shaft anti-clockwise. In a modified form one spring only is employed connecting the ends of spring-straining levers. The carrier in this form has a triangular projection which is engaged by these levers. A construction of multiple contact switch to which the switch actuating mechanism already described may be applied is shown in Figs. 25 and 26 the rotatable bar A carrying two part spring contacts which engage with sets of fixed contacts K adjustably mounted in carriers M on bars J arranged parallel to the switch axis. The moving contacts (Figs. 29 and 30) consists of phosphor bronze blades 0 clamped in holders Q and bearing at their outer ends copper contact pieces P which engage similar contacts K (Figs. 27-28) mounted on phosphor bronze blades k' clamped in recesses in the holders M.

A bimetallic element 2 has a flat portion 5 which is adapted for connection e.g. by means of a bolt to the sole plate of an electric iron, the portion 5 being divided into sections 13, 14, 15, 16 by means of grooves 9, 10, 11, 12 formed in a surface of the portion. The element 2 is bayonet shaped, and when fitted in an electric iron the end of the element 2 remote from the portion 5 actuates switch contacts in the heater circuit of the iron (Fig. 1, not shown). The grooves 9, 10, 11, 12 are made in the surface of the element which becomes concave on heating and preferably cut substantially through one layer of the bimetallic element. The grooves may be radial from a central hole 17 for the fixing bolt or may be concentric, and the effect of these grooves is to prevent flexing of the element in the region of the bolt and thus prevent loosening of its fixture. The element 2 may be provided with a coating to absorb heat and conduct it to the element.
