UNITED STATES PATENT OFFICE.

CLARENCE M. HOWARD, OF FREDONIA, NEW YORK.

WATCH-REGULATO R.

SPECIFICATION forming part of Letters Patent No. 239,167, dated March 22, 1881. Application filed December 1, 1880. (Model) To all whom it may concern:

Be it known that I, CLARENCE M. HOWARD, of Fredonia, in thescounty of Chautauqua and State of New York, have invented certain new and useful Improvements in Regulators for Watches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in regulators for watches; and it consists in using teeth upon the outer edge of the balancecock for the indicator to catch in, and thus prevent the indicator from being jarred or shaken to one side or the other.

It further consists in making a curved slot through the balance-cock, and having a small pin or projection which extends do wn from the under side of the indicator and projects through this slot and catches in the spring, and thus regulates its throw, as will he more fully described hereinafter.

Figure 1 is a plan View of my invention. Fig. 2 is an edge view of the same. Fig. 3 is a vertical section of the same.

A represents the balance-cock, upon which the regulator B is secured in the usual manner. Secured to the shoulder on this cock is a curved plate, C, which has a series of very fine teeth or notches made in its upperedge, and which teeth or notches projectjust far enough above the top of the cock to allow the regulator B to catch in them. Also secured to this cock is a guide, G, which extends along just over the top of the teeth, and serves to both prevent the outer end of the indicator being raised up too high and to guide the regulator back and forth in its movement. Should it be so preferred, the teeth may be placed upon the under side of this guide instead of upon the plate, and in that case will act in the same manner as already described. When the teeth are placed upon the plate, as here shown, the

indicator presses downward upon them with justsufticient force to prevent the indicator from being shaken orjarred outof position, but not with sufficient force to prevent the indicator being moved when force is applied to it. When the outerend of theiinlicatoris slightly raised it frees itselt'from the teeth and moves without any friction. Should these teeth be made in the lower edge of the guide, it will be necessary to have the indicator bear upward instead of downward, and to depress its outer end in moving it back and forth. 4

Through the top of the cock, at any suita-' ble distance from the hub upon which the indicator moves, is made a circular slot, 0, and projecting down through this slot is a pin, V, which catches in the spring for the purpose of controlling its throw or movement. This pin is secured directly to the indicator, and being protected or moving between solidplates there is no danger of its being bent or injuredin any manner.

Should it be preferred, the toothed plate and the guide will be made in one solid piece instead of in two separate and distinct pieces, as here shown, and thus make it easy to adjust into position.

Having thus described my invention, I claim- 1. In a watch-regulator, the combination of a cock, A, having an ott'set or shoulder, with a stationary notched or toothed plate. C, secured to the shoulder, and the regulator B, having its outer end extended out over the top of the plate, substantially as described.

2. In a watch-regulator, the combination of an indicator, a notched or toothed plate, and a guide, the guide and plate being made in either one or two pieces, substantially as set forth.

In testimony that I claim the foregoing l have hereunto set my hand.
