Specification of Letters Patent.
Patented Mar. 8, 1921.
Application i'iled May 8, 19:20. Serial No. 379,901.
To all 10km/Lit' may concer/z Be it known that I, CnnLisLn F. Barrier, Sr., a citizen of the United tates, residing at und whose pest-oliice address is 1l hlorth 30th street, city of Richmond, county of Henrico, State of Virginia, have invented certain new and useful Improvements in Jewel-Setting rTools, and l do hereby declare the following to be a full, clcanand exact description of the invention, such will enable others lied in the art to which it appertains to malre and use the saine.
The invention relates 'to a sirnple and eilicient tool for setting the jewels in d ouble roller-tables of watches and the like, as will be more particularly `des ribed in the annexed specification and illustrated in connection with the accompanying drawings in which latter Figure 1 is a plan view of the preferred tone of the tool.
Fig. 2 is a bottom plan thereof.
Fig. is a vertical transverse section through the device, on a considerabljy enlarged scale.
Fig. e is a perspective view of the roller- 'rable supporting and jewel 'i ing.
Refering to the drawings, indicates a base or support .vhich may be conveniently made in disk forni, the baclr portion of which is turned out to leave an annular central projection 3, and a peripheral flanee 2. The upper face of the base, which is otherwise flat, is provided with a transverse recess el, provided with a central circular di Vpression 5, preferably located at the center of the base. Secured to one side of the base, and preferably at right angles to the transverse recess el, is a handle 6 by means of which the tool is supported.
livoted on suitable screw stud l1, near one end of the recess il, is a lever 10, having a cut-away central portion terminating in a knife edge 12 which normally engages the adjacent wall of the recess, againstwhich the levei` is held hy means of a spring 18, secured bva screw 14; to the face of the base. One of the lateral walls of the recess is tapered or divergent with respect to the other side to permit a limited movement of the lever in the recess and permit the lever to be swung so that its upper edge moves out of engagement with the opposite wall of the recess.
Piercing the base 1, and eiicising a small section of the upper wall of the recess 4, is a circular opening 19 in which is situated a bushing l5, preferably of steel or other hard metal, which is adapted to be logked in adjusted position within the opening 19, by a set-screw 2O passing through the flange 2 of the base and into the peripheral edge of the central projection 3, as shown in Figs. 2 and 8. Said bushing is provided with an eccentric bore 1G, which intercepts or eXcises the side wall of the bushing and forms two horn-like clamping members 18 which are separated ij a short interval and servo as two of the-clamping elements for the jewel to be set. The lateral wall of the bushing 15 is pro ided with a cross-cut 17 below the clamping jaws 18, as shown in Fig. 4l to provide an open space to admit one edge of the jewel-supporting table.
ll'ounted for vertical adjustment in thel rcntral recess 5 in the base, and lying below the bottom of the groove 4- is a jewel supporting table 28 which is provided 'with a central screw-threaded stem 24- which eugages a screw-threaded opening in the center of the depression 5 in the base, so that, by turning Vthe threaded stem 24, the table Q8 is raised or lowered to accommodate jewels of vdifferent lengths and to effect the nicety of adjustment required, the threads in the stem 2li are preferably made very line. rllhc table 28 is preferably made of very thin steel so that the thickness of the peripheral edge of the able may be reduced to clear the lower flange of a double roller-table when the latter is applied to its proper position within the bore 16 of the bushing-15, as illustratcd in Fig.
ln applying the tool to its intended use, the jewel to be set in the double roller-table is clamped in position between the clamping jaws 18 and the bushing 15 and the knife edge 12 of the lever 10, with the lowerend of the jewel resting on the supporting` table Q3, as shown at X in Fig. 3, said table 23 having been properly adjusted to the length f the jewel. T he double roller-table is tien dropped into the eccentric bore 16 of die bushing 15 and canted slightly to cause be lower vliauge ofthe roller-table to clear marginal edge of the jewel supporting `able 23, the roller-table being then adjusted to bring the ewel socket in the upper 'flange into registry with the upper end of the ewel and, inasmuch. as the jewel is rigidly held in position by the clamping jaws 18, the knife ywithout danger of displacing any of the parts. After the jewel has been thus inserted in position in the roller-table, the
The bushing l5, it will be noted, is removable and may be replaced by similar bushings having different sized bores to accommodate various size roller-tables. Also, as heretofore indicated, the jewel supporting table 23 is adjustable to permit the device to be used in setting jewels of diderent lengths Y and also to coperate with the various sized bushings employed. lVhile these features of the variable bore bushings and adjustable j ewel'supporting table are highly desirable in a toolr of this character, to permit the same to operate with various sized double rollertables and variable length jewels, it is nevertheless to be understood that the invention is not limited to either the removable and replaceable bushings or to the adjustable table, as it is obvious that the tool may be constructed with a single fixed bushing and also a fixed table which will enable the tool to be used for setting jewels in a single type of double roller bearing without` requiring any adjustment or substitution of a different sized bushing or any vertical adjustment of the table. Likewise, the shape or configuration of the tool as a whole may be varied to accommodate the exigencies of any class of work, or the convenience of the operator, provided, however, that the essential chan acteristics of the device, involving the particular relation of the eccentrically bored bushing with its spaced clamping jaws, the pivoted lever with its knife edge, and the means of supporting the lower end of the jewel when the latter is clamped between the j aws and the knife edge, are preserved.
