IMPROVEMENT IN REGULATORS FOR WATCHES.

Specification forming part of Letters Patent No. 59,394, dated November 6, 1866.

To all whom it may concern:

Be it known that I, ALBERT HILL, of the city, county, and State of New York, have invented a new and useful Improvement in Regulators for Watches; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a face view of the front plate of the works of a watch with my improvement applied; Fig. 2, a section of the same, taken in the line x :r, Fig. 1 5 Fig. 3, a detached view of a cap-plate pertaining thereto.

Similar letters of reference indicate like parts.

The object of this invention is to obtain, by a very simple and inexpensive attachment to the regulating mechanism of awatch, a means by which the pointer or regulator may be adjusted with a much nicer degree of accuracy than hitherto, and which will admit of any one adjusting the pointer or regulator at any time without the aid ofa magnifying-glass and without exercising any special care.

A represents the front plate of the works of a watch. B is the balance-wheel; O, the spiral or hair spring, applied to the balance-wheel in the usual way, and D,the regulator or pointer, the outer end of which is moved over a graduated are, a, on plate A. These parts, being all old and well known, do not require a minute description.

E represents a plate, one end of which is curved and toothed, as shown at b, and the opposite end has a circular hole made in it, so that it may he fitted upon the annular bearing 0, in which the jewel of the arbor of the balance-wheel is fitted and works. The toothed end b-of the plate E is a portion of a circle, of which the arbor of the balance-wheel is the center. The end of the plate E, which is fitted on the bearing 0, has a ridge or edge, d, extending around its opening concentric with the bearing 0, and on which ridge or edge the inner end of the regulator or pointer D is fitted and allowed to turn, the friction being sufiicient to cause theregulator or pointer to move when the plate E is moved. F is a pinion which gears into the toothed end I) of the plate E, the axis of said pinion being in the plate A, and having a pointer, G, attached to it, which works over agraduated are, (1*.

From the above description it will be seen that by moving the pointer G the plate E will be moved, in consequence of the pinion F gearing into the toothed end I) of the plate, and the pointer or regulator D also moved, as it always moves with plate E; and it will further be seen that the pointer G will be moved over quite a large space compared with the pointer or regulator D, owing to the connection of G to plate Eto wit, the pinion F and toothed end I) of said plate. Hence, by moving the pointer G, a verynice adjustment of the pointer orregulatorDmaybeobtained. Thelattermay be moved the onesixteenth of a degree over its are a without the aid of a magnifying-glass, for to effect that the pointer G requires to be moved one-sixteenth of the whole length of its graduated are d", the pinion F having in this instance the number of teeth to accomplish that result. The pointer or regulator D may at the same time be adjusted directly whenever required, as its inner end will slip over or around the edge (I, owing to the friction required for the toothed end I) of the plate E to turn pinion F. The latter therefore serves as a stop for said plate. The plate E is covered by a cap-plate, H. (Shown in Fig. 3.) The pointer or regulator D is connected with the spiral or hair spring 0 in the usual wayto wit, by means of two pins, 0 c, the springpassing between said pins.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is v The combination and arrangement of the plate E, having toothed curved end I) and ridge d, pointer D, pinion F, pointer G, and arcs a d", relatively to each other, and operating in the manner and for the purpose specified.

ALBERT HILL.
