UNITED STATES-PATENT OFFICE COMBINATION VISE AND DRILL GUIDE FOR WATCHMAKERS 1 Claim.

More specifically, the invention has to do with a combination vise and drill guide which is appropriately made and designed to securely clamp the rim portion of a balance wheel in an established position and in exacting relation to a drill during the procedure involved in drilling balance wheel screw holes or dislodging and removing broken balance wheel screws.

There has been a long-felt need for a simple. efilcient and economical tool to assist watchmakers in removing broken balance wheel screws from the rim of a balance wheel and/or drilling new holes for the addition of balance screws on said wheel. It is therefore the object of the present invention to provide a tool susceptible of accomplishing the stated results, said tool bein such that it may be securely clamped between the jaws of a jewelers bench vise.

Another object of the invention has to do with perfection of the stated combination guide and vice wherein manufacturers and users will find their anticipated needs fully met, contained and effectually available.

Other objects and advantages will become more readily apparent from the following description and the accompanying illustrative drawings.

In the accompanying sheet of drawings, wherein like numerals are employed to designate like parts throughout the views:

Figure 1 is an end elevation of the improved combination watchmakers tool made in accordance with the requirements of the invention and showing the manner in which same is anchored in a bench vise, the latter being fragmentarily shown.

Figure 2 is a side elevation of the tool removed from said vice.

Figure 3 is a central longitudinal sectional view through the structure seen in Figure 2.

Figure 4 is a view partly in section and partly in elevation showing the manner in which the vise and drill operate in associated relation with the rim of a balance wheel.

Referring now to the drawings, and first to Figure 1, the numeral 6 designates a vise for use on a jewelers bench, the same characterized by complemental jaws 8 and Ill and an adjusting handle or pin l2 for said jaws. The vise 6 is shown in order to bring out the fact that the tool provided is a sort of attachment to be used on the vise 6. However, the tool is, in itself, a vise, as will be clearly brought out.

Referring now to Figures 2 and 3, in particular. the tubular body of the tool may be suitably described as a barrel l4, the central longitudinal bore l6 of which opens through opposite ends of the barrel. The bore is counterbored at the lefthand end, as shown in Figure 3, and screwthreaded as at 58. There is an extension 20 on the right-hand end of the barrel. This is characterized by a shank 22 carrying a lateral relatively stationary vise jaw 24. The latter has a clearance passage 26 lined up with the bore IS. The surface portions 28 are satisfactorily shaped to conformably accommodate and grip the rim portion 30 of the balance wheel 32. The spokes of the latter are denoted at 34. An extensible and retractible unit is provided and this is denoted by the numeral 36 and it comprises a sleeve 38 which is slidably mounted in the bore and has one end portion 40 projecting toward and lined up with the jaw 24. The end portion 40, therefore, constitutes a relatively movable vise jaw for the balance wheel. The left-hand end of the sleeve is provided with a screw-threaded adjuster 42 which is screwed into the screw-socket l8. The adjuster is provided with a milled or knurled finger wheel 44. The numeral 46 designates a conventional type drill having its twisted or drilling end 48 shiftably and removably mounted in the sleeve. After the rim 383 of the balance wheel is gripped between the jaws 24 and 40, as

" shown in Figure 4, the drill is brought into play in an obvious manner to either drill out a screw, or drill a hole for a new screw. Thus, a simple and practical assemblage of common mechanical expedients herein disclosed provides an efficient and reliable tool for attaining the important ends wanted and so that the device may be used with the vise 6, the barrel I4 is provided on its under side with a gripping block 50 and means 52 where by the block is welded in place.

In view of the foregoing description taken in conjunction with the accompanying drawings. it is believed that a clear understanding of the device will be quite apparent to those skilled in this are. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and desc'ribed a preferred embodiment of the invention, the same is susceptible to certain changes fully compre bended by the spirit of the invention as herein portion screwed into said socket and provided at 15 an outer end with a thumb Wheel, the end of the sleeve adjacent said jaw being projected through the bore and constituting a relatively movable jaw.

THEODORE MICHAEL.
