WATC H PEN DANT.

SPECIFICA'IION forming part of Letters Patent No. 450,579, dated April 14, 1891,

Application filed October 27, 1890, Serial No. 369,475, (No model.)

To all whom it may concern:

Be it known thatI, FRANK G. FAXON, a citizen of the United States, residing at Mount Morris, in the county of Livingston and State of New York, have invented an Improvement in lVatch-Iendants, of which the following is a specification.

The object of this invention is to reduce the weight of precious metal in the pendant and thereby lessen the cost of manufacture, and also to secure the ends of the bow more reliably than in the safety-pendants which have heretofore been manufactured.

In some of the safety-pendants heretofore made peripheral grooves are formed in the metal of the bow near the ends thereof, leaving heads that are received and grasped by notched shells that are secured within the pendant.

By my present improvements the pendant is rendered very strong and durable and the bow is reliably connected thereto, and the strain and wear come principally upon the interior portions of the pendant and but little on the shell of precious metal, and the parts can be separated with facility whenever necessary.

In the drawings, Figure l is a vertical section of the pendant and a partial elevation of the sleeve or tubular screwshanlt. Fig. 2 is an inverted plan, and Fig. 3 a section of the locking ring or bush. Fig. a is a plan, and Fig. 5 a section, of the lower bushing. Fig. 6 is a section of the tubular screw-shank in a modified form, and Fig. 7 is an inverted plan of the same.

The capsule or shell A of the pendant may be made in any desired manner, but it may be thinner than usual and of precious metal or plated. The lower bushing E is in the form of a ring screw-threaded on the inside, and the exterior corresponds in shape to the interior of the shell or pendant A, and such bushing E may entirely or partially till the lower part of the shell A, and it is preferably made with a peripheral groove E, as shown in Fig. 5, so that it will be firmly scoured into the shell of the pendant by swaging or rolling the metal of the shell into this groove, as seen in Fig. 1; but this bushing E may be soldered or otherwise firmly held into the pendant-shell, if desired.

The locking-ring or upper bush F is removably fitted into the shell A of the pendant, and the bow B of the pendant is made with parallel or nearly parallel ends peripherally grooved, as at 2, leaving heads at the extreme inner ends of the bow, and the cross hole that is bored into the pendant for the reception of the ends of the bow is partly in the upper surface of the bushing E and the lower surface of the locking ring or bush F; but a portion of such hole in the locking ring or bush F is formed with semicircular ribs 3 to fit the peripheral grooves 2 in the how 13, and the semicircular recess in the top of the lower bushing E is plain, in order that the ends of the bow B may be introduced freely into the pendant and brought to position, after which the locking ring or bush F is introduced into the shell of the pendant.

The sleeve or tubular screw-shank D is formed with a head that sets within the shell A upon the locking-bush F, and such screwshank passes through the locking-ring F, and screws into the lower bushing E, thereby firmly holding the locking ring or bush F in position and clamping the ends of the bow 13, but allowing such bow to be swung, as usual. The top surface of the bushingE and the bottom of the locking-bush F should be a slight distance apart to allow for screwing up the shank D from time to time to compensate wear or looseness in the ends of the bow, and the head of this screw-shank is notched for the reception of a screwdriver.

The crown G is of any desired character. Usually it is recessed for the upper end of the pendant, and the spindle H, which passes through the screw-shank D, is connected with this crown G, so as to be rotated thereby, and this connection may be made in any usual manner.

In Fig. l the spindle II is represented with an enlargement adjacent to the inner end of the screw-shank D, to prevent the spindle being drawn out, thus adapting the present improvements to watches containing a push- IOO When this improvement is used with a crown winding and setting mechanism, in which the crown is moved to draw out the spindle H or to push it in for winding or setting, then the tubular screw-shank D is preferably prolonged in the form of a thin split tube 6, as shown in Figs. 6 and 7, with an in wardly-projecting inclined flange, so that the spring-tube will hold thespindle H in its normal position for winding, or allow such spindle to be drawn outwardly to connect the same with the hand-setting mechanism. I provide a small hole at 8 in the crown, which hole is in line with the cross incisions in the head of the tubular screw-shank, so that a pin inserted into this hole 8 will pass into one of such incisions and connect the crown and the tubular screw-shank, so that the latter may be rotated to tighten the parts up, as may become necessary. By unscrewing the tubular shank the winding stem or spindle can be withdrawn to allow the movement to be taken out of the case, thereby doing away with the separate fastening-screw that is usually provided.

I claim as my invention 1. The combination, with the shell A, of a bushing fitting the interior of the pendant and permanently secured to the same, said bushing having a central screw-threaded hole, the bow having peripheral grooves near its ends within the pendant, the locking-ring within the shell of the pendant and having ribs to fit the grooves in the bow, and atubularscrew-shank passing through the lockingring and screwing into the bush to connect the parts together and secure the ends of the 1 how, substantially as set forth.

2. The pendant-shell, and the bushing received within the same and permanently secured thereto, in combination with the how, the ends of which pass through the shell and into recesses in the upper surface of the bushing, the locking-ring within the shell and having projections that engage recesses or grooves in the bow, a tubular screw-shank passing through the locking-ring and screwing into the bushing and having a head pressing upon and securing the locking-ring, such head being slotted, the crown, and the spindle to which the crown is secured, and which spindle passes through the tubular screwshank, there being a hole in the crown for the insertion of a pin through the slot of the screw-head, substantially as set forth.

3. The shell or pendant and the bushing within the same permanently secured thereto and having a central screw-threaded hole, in combination with a locking-ring Within the shell for securing the ends of the how, a tubular screw-threaded shank provided with a head for holding the locking-ring in position,

and a thin tubular extension slotted to form springs, and a spindle within the screw-shank and the crown connected with such spindle and adapted to move the same endwise, substantially as set forth.

Signed by me this 22d day of October, 1890.
