Be it known that I, \VILLLUI S. SCALEs, of Somerville, in the county of Middlesex and State of Massachusetts, have invented an Im- 5 provement in Controlling Devices for the Regulating Members of Clocks, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has forits object to provide means for regulating clocks from a distance,

whereby the regulating members of one or several secondary clocks maybe so controlled or governed that the clocks shall be made to gain or lose, as necessity requires, to corre-v spond with the master-clock.

In accordance with this invention, it is designed that the regulating members during each movement shall overcome a suitableresistance, and that this resistance shall be variable and controllable from a distance, as

l i l from the master-clock. As a preferable way to carry out my present invention, a flat sprin or spring-like strip is attached at one end of the verge of the escapcment or to the penduhim-rod, and the outer or free end of the said spring is held by an operating lever or bar controlled, directly or indirectly, by an electro- Q cuit caused by the master-clock. Any movement of the operating bar or lever lengthens or shortens the spring, so as to increase or decrease its reacting force or to vary the resistant ot' the regulating member. The spring may be attached to the operating-liar and its end be held by a bar or lever-rigidly attaehml t0 the verge or pendulum or to the pendulum direct.

Figure 1 shows the eseapement of an ordinary clock and means for varying the ,res'st ance of the verge in accordance with this invent-ion. Fig. 2 is a detail showing the vari able resistance connected with the pointer, and Pi is a modification to be referred to.

Referring to Fig. l, the escape-wheel (I and the verge l) are as now common in ordinary clocks. The resistant shown in Fig. 1. consists of a fiat spring, I), or a spring-acting strip, one end of which is attached to the verge I), while its other or free end is held loosely beo magnet which is effected by changes in a cir tween two pins, 2, attached to or projecting from the operating bar or lever (7. pivoted to the upper end of a lever, the said operating bar or lever 1] being moved horizontally or l longitinlinally in one or the other direction by 3 the lever c. As the operating bar or lover (I is thus moved ln'irizontally or hmgitudinally,

the spring 1: is lengthened or shortened. The lever fis pivoted at or near its center. as at f, and has loosely (onuected with it at its lower end a controllinglever, e, having upon its under side a projection or ear, 7, provided with a V-shaped recess. The lever c at its outer end rests upon or between pins -.l', attached to the lever c, pivoted at v, the outer end of said lever cz'irrying the armature I5 of the electro-magnet c". The lever 1' also has an ear, 3, provided with a pin which enlers the V-shaped notch in the disk 20. An arm, S, is fixed to the shaft, upon which the disk 2o is mounted, which co-operates with the V- shaped ear 7 of the lever c.

The levers c and w and the co-op(i-rating parts are the same as shown in application for United States Patent, Serial No. $35,454:, tiled by me November 13., 'lSRT, and indicated by like letters, to which relm-ence may be had.

It will be seen that as the verge I; is moved the spring Z1 is bent lirst in one and then in So the opposite direction, and whenthe verge is at an intermediate point the spring otters no j resistance; but asthe spring isbent in oneor the other direction. by the movement of the verge the resistance gradually increases.

As the lever d is moved in one or the other direction longiludinally,1he spring is lengihened or shortened, and hence the resistz'lnee varies. l herein term theresistant a variable resistant,meaning one in which Ihe resistance gradually increases as the verge moves in one or the other direction, and not to the variations given to the resistanceby the longitudinally-moving rod (7, such movement increasing or decreasing the amount of variations.

In Fig.2, l have also shown the resistant as a flat spring, 1', attached at one end to the pendulum 1', its outer or [free end being held by an operat ing bar or lever, adapted to he moved to lengthen or shorten the spring.

In Fig. 3,1 have also shown a tiat spring, a, as a resistant, itbeing attached at one end to the longitudinally-opcrating bar or lever, n, and its outer or free end being held by a lever or arm, n fixed to the vergeof the escape ment.

In the instances shown in Figs. 2 and 3 a similar result is accomplished as by the device shown in Fig. 1..

I claim 1. The combination, with the escapement (L and verge b, of a resisting-spring for the verge, the operating bar or lever for varying the force or resistance of said spring, and an electro-magnet for moving or controlling the movement of said operatin bar or lever, substantially as described.

2. The combination, with the regulating or G. W. GREGORY, F. L. EMERY.
