. IMPROVEMENT IN PENDULUNPCLOCKS.
Specification forming part of Leiters Patent No. 161.674, dated April G, 1875; application filed February 4, 1875.
To all whom 'it may concern:
Be it known that I, FREDERICK EcKEL, of the city of New York, in the county and State ot' New York, have invented a new and linproved Pendulum-Glock, of which the following is a speciiication Figure l is a face view of a clockescapement provided with my improvement. Fig. 2 is a vertical transverse section of the same.
Similar letters of reference indicate corresponding parts in both figures.
This invention relates to that style of pendulum-clock which has a dexible joint formed between the anchor oi" the escapement and the of vibrating on the pin b, which allows the clock to operate properly, even if the frame should not stand or hang,I quite perpendicular. The lugs d d, of the anchor B, are perforated to size to admit the said anchor to be screwed upon the tube a, and said lugs have, therefore,
(or at least one of them has,) a female screwthread matching the screw a. Being screwed upon the tubular screw a, the anchor is supported by the same on the pin I), the screw a constituting the pivot of the anchor. ln normal operation the anchor will vibrate with the crutch-wire on the pin b but the crutch-wire, if it needs to move independent of the anchor, will swing by turning` the tube a within the lugs of the anchor. The axis of the anchor and that of the crutch-wire joint are thus identical. A suitable spring-latch, e, bears on the end ofthe pin b to prevent the tube a sliding off. The screw-thread on a will cause suiicient friction to insure joint movement of anchor and crutch-wire during normal action, and only when the pendulum swings farther to one side, owing to an inclination of the clock, will the crutch-wire follow without carrying the anchor along.
l do not cla-im to have invented a joint between crutch-wire and anchor, which is the invention of V. Himmel, but I do claim as my invention- The combination ofthe crutch-wire C, which carries the tubular screw a, with the fixed pin b, and with the anchor B, having; the threaded lug d, all arranged substantially as herein shown and described.
