Be it known that I. A. C. CROSBY, of' Piqua, in thecounty of llIinmi, and State of Ohio, have invented certain vnew and useful Improvements in Jewelling Watches; and I do hereby declare that the following is n. full and complete description ofthe same, reference being had to lthe accompanying drawings, making a part of this specitieaition, in which- Figures 1 and 2 are side views ofthe instrument.

Figure 3 is o. watch-plate.

Figures 4 and 5, transverse sections of the same.

Like letters of reference refer to like parte in the views.

In the above drawings, A, g. 1, is a hub or sleeve, in which is fitted a spindle, B, the,.lower end of which is drawn down to a ne tapering point, X, und 'the upper end termina-tes inn lnob or cup, C. Fixed to two opposite sides ofthe hub is a. pair of spiingarms, D, so directed that the extreme points, a, press against the spindle, as shown in iig. 1; the inside of the points being made-concave, so as to fit closely and prevent'slipping. It will also be seen that the outside of the points is slightly curved, the purpose of' which will be hereafter shown. -E is a. set-screw, for the purpose of holding the spindle from turning in the sleeve or hub.

`In order to understand the application of this tool, we will first describe the jewel-set and bezel by which thejewe] is secured in the plate, g. 4 representing a. transverse section of the watch-plate, iig. 3, and in which b is thejewel-seat. It will be seen that the position of' the bezel C is such that the jewel could not be placed upon the seat without rst forcing back the bezel to the position shown in iig. 5. 'lhis is done by introducing the point of the spindle into the journal-hole or sent e, and then bringing the points ofthe arms within thecircle ofthe bezel, resting the extreme ends upon thejewel-seat, so that the edge of the bezel will lie in the curve a.

Now, on gently pushing down the spindle, and at the same time turning it and the arms around, the bezel will be crowded back from over the jewel-seat, as shown in fig. 4. The spindle, during the operation, serves as a pivot, stendying and regulating the outward pressure of the arms, so that each arm is pressed out equally.

Should any portion-of the bezel be broken away, which is not unfrequently the case, the points will not fall into the breach, and thereby break away the remaining portion of the bezel. The spindle, by filling thejournalhole, effectunlly prevents any sudden and unexpectetlside movement; hence the bezel will be forced back with safety, even should a portion of it only remain.

It will be obvious 4that this instrument is applicable to different sizes ofjewel-seats, and that it can be used equally well without the set-screw E, the screw being intended simply to hold -the spindle in the hub, when turning the instrument by the spindle, instead of turning by the liub,'ns may best suit the convenience of the operator. t

What I claim ns my improvement, and desireto secure by Letters Patent,is-

The adjustable tapering spindle B, the spring-arm D, with or without the curves a, in eombinatibz: with the hub or sleeve A, for the purpose and in the manner set forth.
