UNITED STATES PATENT OFFICE.
'VITALIS HMMER, OF NEW YORK, N. Y.
oiaoUlT-BREAKER Foa PRIMARY ELECTRIC CLOCKS.
SPECIFICATION forming part of Letters Patent No. 3,5520, dated January 11, 1887.
Application filed January 14, 1886. Serial No. 188,531'. (No model.)
To @ZZ whom it may concern:
Beit known that I, VrTALrs HTMMEE, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Circuit-Breakers for Electric Clocks, of which the following is a speci-4 fication, reference being had therein to the aceompanyin g drawings.
My improvement is designed to be used in connection with the central clock oi the system by which the secondary clocks embraced in the circuit of said central clock are run in the ordinary vwell-known manner, being actuated by the pendulum oi' the central or primary clock to make and break the circuit; and its object is to obtain a circuit-breaking mechanism which, while it offers the least possible resistance to the motion of the pendulum of said central clock, secures a make and break of the circuit with each swing ol'l the pendulum.
My invention is illustrated in the accompanying drawings, in which similar'l letters and numbers refer to similar parts throughout the several iigurcs.
Figure l represents airont view of the invention, showing its connection with the pendulum-rod. Fig. 2 is aside view ol' said mechanism. Fig. 3 is a view of a portion thereof, showing certain parts oi the construction more in detail.
Although it will in general be necessary to use only one of said circuit-breakers upon each central clock, yet in order to secure greater certainty of action, which might be made necessary by a temporary derangement of said circuit-breaker, I prefer to use two upon each clock.
Referring to Figs. l and 2, B is the pendulum-rod, which is slotted at S.
XV is a lever, the upper end of which is bent and rests in the slot S, as shown in Fig. 2, so that it rocks with the pendulunrrod. The lower end ol` the lever XY is rigidly attached to the sleeve A, Fig. 2, upon the arbor p, one end of this arbor p resting in the plate D, secured to the back of the clock, and the other end resting in the bracket T. K
L is a bar, which is fastened by a frictionjoint, Fig. 3, to the arbor A, and which bears on its upper side the plate U. This plate U is bent atits ends, as shown, and its curvature is adjusted by the screws si s2. A The bar L and plate U thus rock as the pendulunrrod moves the lever `W.
Y is a bar earrying onl its lower side the contat-plates g g', and resting upon the insulating-support X, the latter being made of some insulating material.
t t are pins which passup from the support X and through holes in the bar Y, which are somewhat larger than the pins t t, so that the bar Y is thus secured to the support X, but has a longitudinalf play, so that it will rock whenever either end is pushedv up bythe ends ofthe plate U when the latter make contact with the plates g g.
rIhe bar Y is electrically connected with one pole of the battery by the wire t, and the other pole ofthe battery is connected with the plate U through the wire ffl', plate l), bracketl, wire il, lever XV, arborA, bar L, and plate U. I have found it best in practice to use the wire i2, as, although the current will at times pass into `the arbor A from the plate D through the pin.
a vibrating pendulum, of the lever Narben A, barL, plate U, bar Y, and support X, earrying the contaetplates g g', all arranged in an electric circuit and operated substantially as described. f
In testimony whereof l afiix my signature,in presence ol' two witnesses, this 7 th day ol' Jair nary, 1886.
