of a local circuit controller. Fig. My wherein the s; Ming-mechanism is magnet. Fig. 6 is an aria? side or face, said pairs being arranged at equidistances apart and the detents of each pair being arranged at different distances from the edge of the end wall, so that all the detents 26 are' arranged to move in one path and all of the detents 27 are arranged to move in another path. as the drum rotates. A detaining-lever 30 is provided for holding the drum in a predetermined posi tion with the actuating-disk in position to admit of the projection on the arm 15, entering one of the depressions therein, so that the contact-members are normally disengaged. Said detaining-lever is secured to a pivot-shaft 31 to which an armature-lever 32 is secured, the armature :13 of which is arranged for cooperation with a relay-magnet 34, which is arranged in the controllingcircuit in any usual or suitable manner. Said detaining-lever also hears a timingelement which is arranged for engagement with the toothed edge of the end wall of the drum but is normally disengaged therefrom when the detaining-lever is held by the attracted armature, and is permitted to move into engagement therewith upon retraction of the armature. Said timingelcment, as here shown, comprises a toothed wheel 36 see red to' a shaft hearing an escape-wheel 37, which is engaged by a pallet 38, secured to a shaft 39, all of said shafts being borne by the detaininglevcr. The engagingportion of the detaining-lever, which is arranged for engagement with the detents on the drum, consists of an angularly formed extension, and said engagingportion normally engages one of the detents nearest the edge of the end-wall, being the outermost detent of the pair, when the armature is in its attracted position, but upon retraction of said armature said engagingportion is moved to disengage said detent and to move into position to engage the other or innermost detent of the next pair, which is arranged in the other path or remote from the edge of the end wall of the drum, thereby to check rotation of said drum, in case said detainingdever still remains in such position at the moment the said detent arrives in position to engage it, but in case said armature should have been attracted in the meantime then said engaging-portion will engage the outermost detent of the next pair of deteuts, thereby to check rotation of the drum.

It will be observed that upon retraction of the armature the tootlual-wheel of the timing-element is moved into engagement with the toothed end-wall of the drum. thereby to retard rotary movement of said drum during the time engagement continues, thereby insuring a prtaletermintal period of time of operation for said drum each time the armature is retracted. The several pairs of detents are arranged relatively to each other to correspond With the depressions in in the controlling-circuit, rotary movement of the drum will be checked by one of the innermost detents but at such time the arm 15 will be permitted to move inward to enter one of the depressions, more or less, so as to permit separation of the contactmemhers, and upon subsequent attraction of the armature said drum will be again released and permitted to rotate. but such subsequent rotary movement will be short and of very short duration, particularly as the drum is at such time unrestrained. and the result of such short movement of the drum will be inconsequential.

It is important that the spring for moving the drum shall be energized automatically as it is not convenient or desirable to provide a long spring which may be manually wound and arranged for many repeated operations. Hence means are herein provided for winding said spring by means controlled by a magnet, which is arranged in the localcircuit or by the relay-magnet itself.

Referring to Figs. 1, 2 and 4., a magnet 40 is arranged in the local-circuit, the armature'lever 41 of which bears a rack-bar 42, arranged for engagement with a ratchetwheel 43, which is secured to the shaft or hub connected with the inner end of the spring 21. and upon att action of the armature of said magnet said spring will be energized. Referring to Figs. 5 to 7 a similar arm 45, is secured to the armatureshaft of the relay-magnet, said arm bearing a rack bar 46, which is arranged for engagement with a ratchet-wheel upon attraetion of the armature to energize the spring. The construction of the means here shown for winding the spring, however, may be changed,-so far as my invention is concerned, as it not material, the main point being that the spring is wound automatically by means controlled by a magnet in the local-circuit or by the relay-magnet.
