CH RONOMETER-ESCAPEM ENT.

SPECIFICATION forming part of Letters Patent No. 283,349, dated'August 14, 1883.

Application filed October 1, 1881. (ModeL) To all whom it may concern:

Be it known that I, AUGUST WV. KIENTOFF, of Dallas, in the county of Polk and State of Oregon, have made certain new and useful Improvements in Ohronometer-Escapement, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings and letters of reference marked thereon, in which Y Figure 1 is a top View of my improved chronometer-escapement. Fig. 2 is a top view of the lower plate, showing the escapementwheel locked. Fig. 3 is a View partly in section, and Fig. 4 is a detail side elevation of the eseapement partly in section.

My invention relates to improvements in chronometer-escapement; and it consists in the peculiar construction and arrangement of the parts, as hereinafter more fully set forth,

and pointed out in the claims.

In the accompanying drawings, a a. represent two plates connected together by the posts I).

0 represents a shaft journaled in the plates a a and carrying the clock-wheel d, which meshes with the lantern-wheel e or a pinion on the shaft f, journaled in the plates a a, which shaft f also carries the escapement-wheel 71, toothed in the usual manner.

i represents the balance-staff, journaled at its lower end in the lower plate a, and journaled at its upper end ina bridge, g, secured to the upper plate a and projecting over it, the upper plate a being out out to allow the passage of the balance-staff and other devices, hereinafter described. The balance-wheel k is secured to the balance-staff i near its upper end.

Z represents a lug or disk secured to the balance-staff i, and carrying a roller or pin, m, projecting downward, so as to engage with the escapement-wheel h.

n represents a shaft journaled at its lower end in the plate a, to the upper end of which is secured an oscillating lever, 0, cut out near its middle for the passage of the balance-staff i.

.p p represent banking-pieces secured to the upper plate a, near the opening therein, on each side of the free end of the oscillating lever o, by setscrews inserted in slots in the bankingpieces, whereby the latter are adjustable to and from the oscillating lever o, the bankingpieces 1) acting as stops for the oscillating lever 0.

1 represents a coiled spring, one end of which is secured to the balance-staff z, the op posite end passing through a lug on the outer end of the oscillating lever o.

r representsa frame adjustably secured to the upper face of the bottomplate a, and provided with a cross-bar, s, journaled in the sides of the frame, to which cross-bar s is secured a vertical locking-lever, t, to the upper arm of which the spring a is secured at its lower end to the locking-lever, lying along and in contact with said locking-lever and projecting slightly above it at its upper end. The upper end of the locking-lever lies in the path of the oscillating lever 0, and its lower end, when thrown inward, engages with a tooth of the escapement-wheel and holds it locked.

o represents a stud secured to the upper face of the lower plate a, and provided with a spring, '10, the free inner end of which presses against the upper arm of the locking-lever i, so as to throw inward the lower arm of the lockinglever and lock the escapement-wheel. Motion being imparted to the balance-wheel, the lever o is oscillated by means of the coiled spring q, and, striking the lever 15, the latter is unlocked from the escapement-wheel, a tooth of the latter striking the roller m, which moves the balance-staff and balance-wheel, the spring 10 throwing the lever i into lock with the escapement-wheel after it has moved the dis tanceof one tooth.

Having thus fully described my invention,

-what I claim as new, and desire to secure by Letters Patent, isp 1. The combination, with the escapementwheel h, of the balance-staff z, carrying the balance-wheel Ia and roller m, spring q, oscillating ,lever 0, and locking-lever t, substantially as described, and for the purpose set forth.

2. The combination, with the escapement wheel 71, balance-staff i, roller m, spring q, and oscillating lever o, of the frame r, cross-bar s, locking-lever t, and springs a 20, substantially as described, and for the purpose set forth.

AUGUST WV. KIENTOFF.
