To all who/m it lmay concern:

Be it known that l, FRANK H. Fnnatn, citizen of the Republic, of France, residing at Granite City, in the county of Madison and State of lllinois, have invented certain new and useful Improvements in Electric Clock liVinding lilechanisrn, of which the lol* lowing is a full, clear, and exact description, reference being had to the accompanying drawings, forming apart hereof.

My invention has relation to improvements in electric-clock winding mechanism and it consists in the novel arrangement and construction of parts more fully set forth in the specification and pointed out in the claim.A Y

In the drawings, Figure l is a side eleva tion of a clock with the driving lever about half descended Fig. is a rear elevation of the same 3 Fig. 3 is' an enlarged side elevational detail of the end of the long arm of the armature-lever; and Fig. 4.- is a sectional detail on line 4---4 oi Fig.

The object of my invention is to construct an electric clockwxinding mechanism made ol a simple set of electro-magnets; one having no expensive contacts; one possessing a minimum number of parts; one which is simplel and positive in action, and. one having turther and other advantages better apparent from a detailed description of trie invent-ion which is as follows1 A Referring to the drawings, C, represents a cloclr of any conventional design having a winding shaft or arborS as usual. Connected to, or forming an integral part of the gea r 1 on the shaft S is a ratchet disl`v with shaft S immediately below the adjacent ends of the energizing coils E, E, the armature being secured to a plate 65 forming the short. member or arm of the armature lever. of the terminal Wires w of the coils E, E, leads to one pole or terminal of a suitable battery or other source of electric nergy (not shown). 'The other terminal ur the drir .vhicli cooperates a. pavrl 3 carried by the weighted said frame conducting' the current through the lever 4, pin 5, arnniture lever 6', and Wire le hach to the opposite pole or terminal of said battery or son ce of electric energy.

llrhen the driving lever 4. is in its highest position (Fig. i) the pin is disengaged from the armature-lever 5but as soon as the clocl: runs down, that is when the lever 4 has dropped to its loivest'position, the contact between the pin 5 thereoia and the armature lever 5 at once closes the circuit, which suddenly energizes the coils il), E. These in turn suddenly draw the armature inwardly, which. has the effect of suddenly throwing the long arni ol" the armature lever outwardly. T his sudden outward movement or oscil lation of the long arm of the armature lever, contacting as this arm does with the pin e, has the eliiect of tripping or throwing g lever fr upwardly, in which upnent the pawl 3 thereof simply teeth of the ratchet 2, the ever Uhr to its highest posito again propel the fhis action is repeated indefinitely. to he noted ot' course, that the armature lever is properly insulated from the clock-Danie so it is only serviceable as an electric conductor when the pin 5 of the driving lever comes in contact therewith as the eicel: runs down. The armature lever is so mounted and Weighted as to normally -troep the armature il a slight distance from the coils E, E, 'the base of the armaturelever being provided with' a laterally mounted la ing screv.rt) (for the Wire which C; i a notch l0 l'orined l'or its reception in the clock-trarne.

Having described my invention, What l isz-- combination with a clock-mechanism having a, Winding shaft, a Weighted driving lever loosely pivoted at one end about the shaft, a pawl on the lever, a ratchet disk carried by the shaft and engaged by the pawl, a laterally projecting impact pin at the base of the driving lever, yan energizing coil, an insulated armature lever having a long and short arm, the short arm carrying an armature in front ot the coil, a conducting wire coupled to the end oi the long arm of the armature lever, a binding screw to secure the wire, the traine of the clock having a notch for receivingthe head of the binding seroit', the pin on the drivinrr lever l I nung A adapted to ContactV with the long arm of the In testimony whereof I alx my signature, rrlatre levier, Wherely thedciruit is closed in presencel of two Witnesses. an t e coi ener ize an t e` armature lever is suddenly osgcillated'thereby throwing I FRANK H" FE'RAUD' 5. the driving lever about its axis of rotation Witnesses:

upwardly thus restoring it to its highest W. E. RoBnRTsoN position,4 substantially as set forth. lW. C. KILLEEN.,
