JEWEL-PIN SETTER.

Application filed December 20, 1923. Serial No. 681,839.

T0 41 whom it may concern:

Be it known that 1, PAUL EMMETT GALAME, a citizen of the United States, and a resident of Holly Springs, in the county of Marshall and State of Mississippi, have invented a new and useful Improvement in a Jewel-Pin Setter, of which the following is a full, clear, and exact description.

My invention relates to improvements in devices for setting jewel pins in watches, and itconsists in the combinations, constructions and arrangements herein described and claimed.

An object of my invention is to provide a device by means of which a jewel pin may be set accurately and quickly in watch rollers, so that the pin is in exact alinement with the longitudinal axis of the roller.

A further object of my invention is to provide a device of the type described, which will hold the pin and which will enable the roller to be held at right angles thereto, so that the pin may be set perpendicre arly to the surface to which it is secured. with very little trouble.

A. further object of my invention is to provide a tool which will hold the pin rigidly while it is being secured in position by cementing.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be parti 'ularry pointed out in the appended claims.

My invention is illustrated in the accompanying drawings, forming part of this ap' plication, in which Figure 1 is a top plan view of the tool,

Fig. 2 is a side elevation of the tool,

Fig. 3 is an enlarged view of one end of the tool, and

Fig. t is an enlarged cross-section of one end, showing its application in the setting of the jewel.

In carrying out my invention, I provide a shank or body portion 1 which is made of metal, and which is provided with a handle 2. his shank is preferably cylindrical, but has a cut-away portion beginning at the point 3 in Figs. 1 and 2, and extend ing forwardly to the end of the device. At l 1 have shown a stud which is secured to the shank in any suitable manner. This stud has a slot arranged to receive a gripping finger 5. The rear end of this finger is pressed on by a leaf-spring 6, which is secured at 7 to the shank, and which bears on the linger in the rear of the pivot pin 8. The front part of the gripping finger is normally held against the fiat surface 9 of the shank 1. twill be observed that the point of contact is very near the end of the shank, since the under surface of the gripping finger 5 is inclined with respect to the flat surface, when the tool is not in use.

It will be observed that the shank 1 isprovided with a longitudinal bore 10, extending inwardly from the end thereof, and that on the upper flat surface is a small V shaped groove 11. This groove is for the purpose of mounting and holding the jewel pm.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. In Fig. 4, T have shown a double roller 12. In re placing a jewel pin, the roller may be removed from the balance staff, or left on the staff, as desired. The broken part of the ruby jewel is removed from the hole in the roller, and a jewel pin of the proper size is selected to replace it. This jewel pin is placed in the groove 10 of the shank, so that it projects beyond the end of the tool, and the gripping finger 5 is released so as to grip the jewel 13. The roller is then brought up, and the pin is inserted in the hole in the roller. It will be observed that the end of the shank and of the gripping finger 5 form a straight edge at right angles to the axis of the bore 10, so that when the roller is placed on the end, and the pin 13 is inserted in the hole, the pin will be parallel to the axis of the roller, and at right angles to the part to which it is to be secured. The pin, of course, is provided with proper cementing material, and the pin and the roller may be held by the tool, which can then be melted over an alcohol lamp or with an electric heater, to cause the cement to flow around the jewel in the hole in the roller. The tool may be then removed from the frame, and the cement will cool so as to hold the jewel in place. In the case of double rollers, the bore 10 allows the guard roller to enter therein, so that the jewel may be properly set.

With this tool, the setting of jewel pins is very readily accomplished, besides resulting in an economy of time 1n setting ewels. It also insures the proper and accurate securing of the jewel in the roller.

It will be noted that the bore 10 is flattened to provide a thin partition between the bore and the groove 11. As Will be seen from Fig. 4, this permits the pin to be s11 ported, While the partition is thin enoug1 to enter between the pin and the hard roller of the smallest of the double rollers, such as those used in bracelet Watches.

I claim:

1. A jewel pin setting device, comprising a shank having a longitudinal groove arranged to receive a jewel, and being provided With an inwardly extending bore arranged to receive a portion of a Watch roller, and a spring finger carriedby the shank and adapted to hold the pin in the groove,

the end of the shank and the spring finger constituting a straight edge at right angles to the axis of the groove.

2. A jewel pin setting device, comprising shank, a handle for the shank, said shank having a central longitudinal bore extending inwardly at one end, a portion of the shank being flattened, a finger pivotally mounted on said flattened portion, said flattened portion having a longitudinal V- shaped groove arranged to receive and center a j eWel pin, and a spring for normally forcing said finger toward the groove, the end of said shank and said finger being flat tened and in a plane at rightangles to the axis of the groove.
