ESCAPEMENT-ADJ'USTMENT FOR CLOCKS.

To all whom may concern:

Be it known that I, AMAsA D. Vroorr, a citizen of the United States, residing at Villisca, in the county of Montgomery and State of Iowa, have invented certain new and useful Improvements in Escapement- Adjustments for Clocks, of which the following is a specification.

This invention relates to adjusting means for escapement devices for clocks and has for its object to provide a means of simple structure which may be easily and quickly adjusted, to cause the parts to cooperate with each other when the clock is in position upon a supporting object.

With the above object in View the invention consists in providing an arm which is pivotally mounted in the frame of the clock works and which is adapted to turn about the axis of the shaft which supports the escapement wheel. Means is provided for turning the said arm in the frame of the clock works. A Verge is pivotally mounted upon the arm and engages the teeth of the escapement wheel and is also operatively connected with the pendulum as will be hereinafter explained.

In the accompanying drawings, Figure 1 is a rear elevation of the clock works provided with means for regulating the escapement. Fig. 2 is a horizontal sectional view of the same. Fig. 3 is a rear view of the frame of the works showing the escapement regulatin device in one of its extreme positions. Fig. 4 is a similar view showing the escapement regulating device in its other extreme position. Fig. 5 is an edge view of parts of the escapement regulating device. Fig. 6 is a perspective view of an arm which constitutes a member of the escapement regulating device. Fig. 7 is an enlarged sectional view of part of the frame of the clock works which supports the escapement regulating device.

The clock works as indicated in general at 1 are provided with the usual escapement wheel 2. An arm 10 is provided at one side and in the vicinity of its upper end with a curved portion 9 which is inserted through an opening 23 provided in the rear part of the frame 15 of the clock works, The inner edge of the opening 23 is beveled as at 24 as best shown in Fig. 7 and the edge of the curved portion 9 is spread as at 25 and fits snugly against the beveled surface 24 in the frame plate 15. The arm Specification of Letters Patent.

Application filed April 26, 1911.

Serial No. 623,538.

10 is free to turn upon the plate 15. The upper portion of the arm 10 partially surrounds the shaft upon which the escapement wheel 2 is located. The arm 10 is provided at one edge and at its lower por tion with a lug 20 which lies between the pins 26 mounted upon the back 15 of the frame of the works. These pins 26 lie in the path of movement of the lug 20 and limit the swinging movement of the said lug and also of the lower portion of the arm 10. The arm 10 is provided with a pin 11 upon which is pivotally mounted a verge 3. This verge is provided with pallets 4 and 5 which are adapted to alternately engage the teeth of the escapement wheel 2 in the usual manner. A rod 6 is connected at its upper end with the verge 3 at one side of the point of pivotal support thereof as best indicated in Fig. 1 of the drawing and the said rod 5 is connected at its lower end with a pendulum device 7 in the usual manner. A rod 12 is loosely journaled at its inner end in the lug 20 but the rod 12 is so connected to the lug 20 that the said lug moves between the pins 26 when the rod 22 is moved longitudinally. The rod 12 is provided with a threaded portion 13 which engages an internally threaded eye 14 which in turn is pivotally mounted upon the rear plate 15 of the clock works. A sleeve 17 is socured to the rod 12 by means of a pin 16 and passes through the side of the casing 18 (best shown in Fig. 1) and is provided at its outer end with a knob 19. Therefore it will be seen that by turning the knob 19 the rod 12 is turned in the eye 14 and by reason of the screw thread engagement between the rod 12 and the eye 14 the rod 12 is moved longitudinally. Thus the verge 3 is moved along the lower edge of the escapement wheel 2. During this adjustment of the verge 3 its point of pivotal connection with the arm 10 is never moved away from the axis of the shaft which carries the wheel 2 for the reason that the said shaft is concentrically positioned with relation to the axis upon which the said arm 10 is turned. Therefore it will be seen that a simple means is provided for properly positioning the verge with relation to a vertical plane which passes through the axis of the shaft that supports the escapement wheel, and thus when the clock is placed upon a support, the parts may be easily and quickly adjusted to cause the pendulum to swing properly with 10 frameopening and adapted to have portions of its outer face expanded into the countersunk edge of the frame-opening to secure the verge thereto.

In testimony whereof I aliix my signature in presence of two Witnesses.
