JOHN T. HEALY, OF ATTLEBOROUGH, MASSACHUSETTS.
FASTENING DEVICE FOR SECURING WATCHES TO CHAINS.
SPECIFICATION forming pait of Letters Patent No. 341,908, dated May 181, 1886.
A pphcation filed October 7, 1885.
T0 aZZ whom, it may concern.-
Be it known that I, JOHN T. HEALY, of the town of Attleborough, in the county of Bristol, in the State of Massachusetts, have invented a certain new anduscful Improvement in Fastening Devices for Securing Watches to Chains; andldeclare the following to be aspeci- .fication thereof, reference being had to the ac conipanying drawings.
Like letters indicate like parts.
Figure 1 shows my invention partly in side elevation and partly in central vertical section. Fig. 2 is a like view of aswivel as con1- monly constructed. Fig. 3 is a perspective view of the body or stem of my improved fastening device;
My invention is a substitute for the swivels used to connect a watch and chain; and it consists ofa body or stem formed in one piece and having the usual bow and springsnap and a ring-link, which is secured to the body or stem directly by soldering.
Watch-chain swivels have hitherto been constructed in the manner illustrated by Fig. 2, in which the body A has an open tubular end, into which is inserted and soldered a plug, B. A ring, G, to which a circular link, D, is soldered, is mounted upon the plug B, and is held thereon by the heading orriveting of said plug, so that the ring 0 may turn thereon; but in practice such swivel-ring is so tightly held as to be quite immovable, while the insertion and fastening ot the plug B in position requires a nuniber ofoperations, which I deem it of importance to avoid.
Serial No. 179,272. (No model.)
In my device I dispense entirely with the plug B and ring 0. In Fig. 1 I illustrate my invention, by which it is seen to consist of a stem or body, E, of peculiar construction, a fixed ring-link, F, and the usual bow, G, and pivoted spring-snap H.
The characteristic feature of my invention, which is shown in Fig. 3, consists of the bulb portion a and the cylindrical portion 1), having a closed end, a. The body or stem, Fig. 3, is formed of one piece ofstock cupped and drawn in the usual manner, and then formed by dies into the required shape, by which operation the end 0 is closed and forms a plane surface. The bow, spring, and snap are secured within the bulb portion a in the usual manner. The
ring-link F is soldered directly upon the cylindrical portion of the stem. By this construction I obtain a fastening device exactly like the ordinary watch-chain swivel in appearance and shape and equally efficacious, but produced more cheaply and with less labor.
I claim as a novel and useful invention and desire to secure by Letters Patent- The herein-described fastening for watchchains, the same consisting of the body E, formed with a bulb, a, to which is attached the bow G- and snap, H, and having a closed cylindrical portion, 1) c, to which is soldered the ringlink F, as specified.
