CHARLES UTAHLFERG, OF CORSIUAXA, TEXAS.
ESCAPEMENT FOR TORSlON-PENDULUMS.
SPECIFJICA'IION forming part of Letters Patent No. 292,870, dated February 5, 1884, Application filed June 12, 1883. (X0 model.)
To aZZ whom, it may concern:
Be it known that I, CHARLES Sari-incline, of Oorsicana, in the county of Navarre and the State of Texas, have invented a certain new and useful Improvement in Escapements for TorsionPendulu1n Clocks, of which the fol lowing is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.
My invention relates to an improvement in the escapement of a clock which is regulated by a torsioirpendulum; and it consists in one or two weighted levers acting in conjunction with an escapewheel and a spindle, which levers are used as a medium to carry force from the train of a clock to the pendulum.
The object of this invention is to cause the impulses on the pendulum to be of equal strength, and to properly arrest and release the train of the clock as the pendulum rotates from right to left.
1n the drawings, Figure 1 represents a back view of the escapement. A portion of the plate of the clock is broken off to fully show the parts of the escapement. Fig. 2 represents a Fig. 3 repre sents a side iew of the eseapement and the pendulum. Fig. t is an enlarged view of the spindle. Fig. 5 is an enlarged top view of the escape-wheel and the repose-plate 011 spindle G. Figs. 6 and 7 are modifications of the escape-wheel and the spindle. Fig. '7 is a top view.
Similarletters refer to similar out the several views.
As I do not claim anything new in the manner of constructing a train of wheels in clocks to carry force from the motive power to the escape-wheel, I will not further describe the same, except to say that the wheel E transmits the force from the other part of the clock train to the escapewheel H by means of gearing, as shown.
B is a support for the escape-wheel, the spindle, and the torsion-spring. It is screwed to the plate A and extends out from it at rightangles.
M is a standard fastened to the plate A, carrying a cross-piece, which supports the levers F and F.
The eseapewheel H is a double wheel of parts throughthree teeth each, both fastened to the same pinion or shaft, and set with alternate teeth equidistant, and also provided with three pins on each side to engage the leversFand F. This escape-wheel has hearings in two standards fastened to the support 13, and the bearings are adjustable by means of screws 0 and c, to bring the teeth of the wheel in proper position with the repose-plate i of the spindle.
G is an upright spindle, pivoted in bearings held by the standard 71.
(l is a cross-piece fastened to the top, for the purpose of receiving the force from the levers F and F.
7a is a cross-piece fastened near the bottom of the spindle, carrying arms, which extend downward with slots at the ends to engage the cross-piece on the pendalum-spring.
i is a plate, also fastened to the spindle, upon which the teeth of the escape-wheel impinge. The bearing-surface, which may be either the upper or the lower, according to the direction that the escape-wheel turns, is polished, and is set, as near as possible, at right angles to the spindle, so that the escapewhecl is neither raised norlowered by theturning of the spindle. The platet' is notched, as shown in Fig. 5, so that when the spindle turns the tooth of the escape-wheel, which rests against this plate, is released and another tooth is arrested on the other side of the plate.
F and F are levers, which are independently pivoted in bearings 011 the standard M. Each has two arms-one, I), to engage the pins on the escape-wheel, the other to transmit force to the spindle G. Each lever is provided with a small weight, a and a, which can be screwed to or from the fulcrum to increase or decrease the power. The arms I) and b are placed at such an angle that when the escape-wheel turns they will be alternately raised by the pins I thereby the weights a and a are raised and power stored in the levers. \Vheu one lever has been raised, it rests 011 the pin Z, then, when the escape-wheel is again released, the pinZ slips away from the lever and the lever rests against the cross-piece (Z of the spindle, and now gives to the pendulum the force which was previously stored. It will be seen from this that the impulse on the pendulum is of constant strength, because the weight of the lever never varies. The levers are placed one on each side of the escape-wheel, and are acted upon alternately.
N is a circular piece of metal, preferably light toward the center and heavier at the rim, acting as a weight, to which is fastened a wire of steel or other elastic metal, either flat or round. The upper end of this wire is fastened to the support B directly under the lower pivot of the spindle G. A cross-piece is fasttened to the upper end of the pendulum-sprin g, to engage the arm k of the spindle, as shown in the drawings.
I do not limit myself to any particular kind of a torsionpenduluni, as that is not a part of this invention; any kind that rotates horizontally and engages the spindle properly will do.
From all this it will be seen that the pendulum rotating from right to left will carry with it the spindle G. This will intermittently release and arrest the escape-wheel H, and the levers will intermittently be raised and give force to the pendulum, thus keeping the latter in motion until the motive power is spent.
It will be seen that the construction of the several parts can be varied in many ways without altering the nature of my invention.
The levers F and F may be made in one piece and weighted in themselves. In the spindle G the cross-piece 7c may be made to do duty for the cross-piece d, and also to form the repose-plate i, and one arm only to engage the pin on the torsion-spring need be used, although I prefer two. The levers may be placed at right angles to their present position and give their force to the spindle by means of inclined planes. The escape-wheel may be varied in shape, the number of teeth may be increased or diminished, and it may also be made in a single wheel, as shown in Figs. 6 and 7. essary. One lever F only need be used, although I prefer two. In this case the alternate teeth of the double escape-wheel should be placed closer together. In the single escape-wheel each tooth should be with two points, or single-pointed teeth can be used with four repose-plates set in doublets. In this way the farthest motion of the escapewheel raises the lever and the lesser one releases the same. The pendulum would receive but one impulse in two beats. The levers may be raised by the teeth of the escape-wheel instead of by the pins, and the escape-wheel may carry the lifting-planes by which the lovers are lifted. All of these modifications would not alter the nature of my invention.
- WVhat I claim as my invention is In combination with the torsion-pendulum of a clock, the levers F and F, the escapewheel H, and the spindle G, consisting of a cross-piece (Z, arms k, and the repose-plate e, substantially as and for the purpose set forth.
