AUGUSTE DARDENNE, OF MARIENBOURG, BELGIUM.
CLOCK-ESCAPEM ENT.
SPECIFICATION forming part of Letters Patent No. 345,486, dated July 13. 1886.
Application filed January 2S, 1886. Serial No 190,034. (No model.) Patented in Belgium August 13, 1854, No. (36,015; in France Ocfober 11, 1584, No. 164,748; in Germany October 15, 1884, No. 31,096, and in England February 6, 1885, No. 1,651.
To aZZ whom it may concern:
Be it known that I, AUGUSTE DARDENNE, a subject of the King of Belgium, residing at Maricnbourg, in the Kingdom of Belgium, have invented new and useful Improvements in Clocks, of which the following is a specification.
The chief impediment to the accurate working of clock-movements as at present constructed arises from the shake or play of the crutch-fork or conneetingrod which connects the crutch or escapement-rod to the pendulum'rod. Different temperatures act on the mechanism of the movement in such a manner that such shake or play is greater under the effect of heat and less under the effect of cold. Heat gives more freedom and cold reduces it.
The present invention has for its object to do away with all kinds of forks orconnectingrods, and to prevent allshake or play between the parts.
In order to enable the invention to be fully understoodfl will proceed to describe the same by reference to the accompanying drawings, which represent two different views of a clockescapement constructed according to this invention, showing the pallets and the escape merit-rod or crutch, the pendulum-rod, and the counter-weight, hereinafter described.
Similar letters in both figures represent similar parts.
In the drawings, a represents a counterweight screwed and adjustable on a screwthreaded rod, 7), which latter is fixed to the pallet-staff c, and forms a right angle with the crutch d, which latter, instead of being terminated with (for example) a fork, is sinr ply turned at right angles at its lower end, 0. The counter-weight a,1ixed horizontally to the pallet-staff 0, serves to constantly press the end f of the crutch (l on one side only of the pendulum-rod g.
h is one of the plates of the clock-movement.
iis the pallet, and j the eseapcment-wheel.
By this arrangement no shake or play can take place between the parts during the toand-fro movement of the pendulum.
Having now particularly described and as certained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is-- 1. In combination with aclock-escapement, a counter-weight fixed horizontally to the pallet statl, in the manner and for the purposes substantially as set forth.
2. The eombinatiomwith the clock-escape ment, of the threaded rod b,its eounter-weigh t, pallet-staff c, crutch d, having a single bent end, of, and pendulum-rod g.
