WATCH-RE GULA'IOR.

Serial No. 424,826.

To all whom it may concern: I

Be it known that I, JOHN J. WIENs, a citizen of the United States, residing at Quincy, in the county of Douglas and State of Washin 'ton, have invented a new and useful Watch-Regulator, of which the following is a specification.

This invention relates to improvements in hair spring regulators for watches, clocks, and other time pieces.

It has for its object to rovide an improved simple and comparative y inexpensive'regulator bar that can be readily applied to almost any watch, clock or other time piece.

Another object is to provide an improved mechanism simple in construction and effective in result, such as can be readily operated to either increase or diminish the vibrations of the hair spring when desired to so regulate the movement.

It is well known that most high class regulators now in use are exceedingly expensive due to the-large number of parts employed in their construction.

The present invention is designed to reduce the number of parts required for a high class regulator to the minimum, and at the same time to produce a construction which will increase or diminish the vibrations of the hair spring to the smallest fraction, thus doing the work of the finest regulator.

With these and other objects in view, as will more fully hereinafter appear, the invention consists in certain novel features of construction and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings :Figure 1 is a plan view of the device applied to the hair spring of a clock. Fig. 2 is a similar view of the device applied to the bridge of a watch. Fig. 3 is a transverse sectional view taken on the line 83 of Fig. 1. Fig. 4 is a detail perspective view of the stud. Fig. 5 is a plan view of the regulating lever. Fig. 6 is a side view of the same. Fig. 7 is a perspective view of the adjusting screw.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawings.

In the construction illustrated in Figs. 1 and 2, the balance wheel 1, hair spring 2, and escapement 3 are of a well known type, and form no part of this invention.

In the present construction, a regulating lever 5 is illustrated, formed of suitable metal, and having one end thereof flattened, as shown at 6. This flattened portion is centrally provided With a transverse perforation for the reception of a shaft 4. The lever 5 is keyed on the shaft 4 and the latter extends beyond the inner face of the lever, and projects through and is adapted to turn in an opening in the frame 7.

A collar 8 formed integral with or otherwise secured to the frame is adapted to encircle the projecting section of the shaft 4 and the latter is secured therein by a set screw 8 as illustrated in Fig. 3.

Adjacent the end of the lever 5 opposite the flat portion 6 is an elongated slot 9 forming a seat for the clamp screw 10 which fits into an opening formed in one end of the bar connecting stud 11.

Adjacent the outer end of the stud is a transverse opening 12 of a width sufficient to accommodate the free end of the hair spring 2, and the latter is secured in the opening by means of the usual wedge 13.

With the construction thus far described, it is obvious that in order to regulate the movement, the screw 8 is first turned to the left, which loosens the stem 4 in its seat. The end of the stem projecting beyond the outer face of the lever is then turned to the right or left, as may be required to adjust lever 5, and when sufficiently turned is locked by tightening the screw 8 In the construction illustrated in Fig. 2, wherein the device is applied to a watch, the bridge 14 has a transverse opening and secured to the lower face of the bridge and registering with said opening is a collar 18 (Fig. 4). A lever 16 substantially the same, but considerably smaller than the lever 5 is provided on one end with a shaft 19 adapted to fit the openings formed in the bridge and col lar 18, and is secured therein by a set screw 20 entering an opening formed in the side of the collar 18. The opposite end of the lever is provided with an elongated slot forming a seat for a clamp screw fitting into one end of the hair spring stud 1.7, the opposite end of the latter being provided with a transverse opening of a Width suflicient to accommodate one end of the hair spring 21. From the foregoing it is evident that the operation of regulating the Watch movement is the same as the one reviously described.

hat is claimed is 1. A hair-spring regulator for time pieces, consisting of a shaft clamped in the frame of the time piece, means for adjusting the shaft in rotative position, a regulator lever arm mounted on said shaft; a hair spring having one end connected to the end of the lever arm; and means for adj ustably clamping the end of the hair spring on the lever arm.

2. A hair spring regulator for time pieces,

consisting of a shaft mounted to turn in and projecting thrcmgh the frame of the time piece; a collar, and set screw on said shaft adjusta bly clamping it to the frame a regulator lever arm mounted on said shaft, and having a slot at its outer end a hair spring, and an adjusting stud and set screw mounted on the slotted end of the lever arm, and clamping the end of the hair spring there to.

In testimony that I claim the foregoing, as my own, I have hereto ajflixed my signature in the presence of two Witnesses.

JOHN J. Wrens.
