Patented Jan. 22, 1895.
Urvrrnio STATES arriva risica.
CHARLES D. SMITH, OF BRDGEPORT, OHIO.
WATCH-DEAL FASTNER.
SPECIFICATION forming part of Letters Patent No. 532,919, dated January 22, 1895.
ApplOttOll filed March 31.1 894- 'Serial No. 505,939. (No model.)
To all whom t may concern.'
Be it know'n that I, CHARLES D. SMTH, a citizen of the United States, residing at Bridgeport, in the county of Belmont and State of Ohio, have invented certain new and useful Improvements in Fastenings forWatch-Dials, dac., of which the following is a specification, reference being had therein to the accompanying drawings.
This improvementis designed to provide a fastening for the feet of watch dials and watch plates, but it may be used for other purposes, such as jewelry for instance, where it will be found a very convenient mode of fastening interchangeable parts, such as initial rings, masonic emblems, duc., whereby such parts may be readily put together and changed as desired.
To these ends the invention consists in the peculiar construction, arrangement and combination of parts hereinafter more particularly described and then definitely claimed.
In the accompanying drawings-Figure 1 shows a plan of part of a watch dial constructed according to my improvement, with parts broken away. Fig. 2 is a vertical section of the same, on the line a: m on Fig. l. Fig. 3 is a vertical section on the line y y on Fig. 2. Fig. et shows a section of part of a ring with an interchangeable set provided with myimprovement. Fig. 5 shows another section of part of a ring on the line econ Fig. 4. Fig. 6 is a perspective View of a locking pin. Fig. 7 is aview of a modification. Fig. 8 is a side view of part of a dial plate and one of its feet. All of these views are on a very much enlarged scale.
Referring now to the details of the drawings by letter-A represents a dial plate provided with feet (indicated at B) each having a notch h, (see Fig. 8) and passing into a hole O in the movement plate D. ln this plate is bored a hole E at right angles to the hole O and with its center on one side of the center of hole O. In this hole is fitted a locking pin F, having one side out away to form a notch j as shown in Fig. 6, so that when turned in one position it forms no bar to the entrance of the foot B into the hole O. Partly surrounding this pin is a groove f, into which passes the end of a screw G, which thus secures the pin in position, and as the groove does not run entirely around the pin, this screw also forms a stop to limit the motion of the pin and prevents its being moved too far when it is being unlocked.
Both the foot and the locking pin may be provided with slits H, which is to make them iiexible and thus form a tension or friction which prevents the rattling or unlocking which might occur but for these slits.
In rings or other devices where there are two or more feet in a line, the locking rod or pin should be long enough to extend from one foot to the other and have a notch for each foot, as shown at F'7 in Fig. 4, and when used for rings there may be holes bored through the locking pin (as shown at h, Fig. 4) by which said locking pin may be turned by inserting a suitable pin in the holes. They may, however, be provided with a slot or a square at the end, if preferred.
The modiiication shown in Fig. 7 has a iinger T projecting from the locking pin, which finger when the locking pin is turned around strikes against a pin l proj ectingthrcugh the casing. In this case the groove f may be eX- tended entirely around the locking pin if dcsired.
When assembling the parts, it is only necessary to turn the locking pin to the left until the stops in the grooves come in contact with the ends of the screws G, and then by entering the feet into the holes C and turning the locking pins, the latter act on the lower parts of the concavities of the notches in the feet and draw them downward so as to make a tight fastening, the lower parts of the notches in the feet being made on a curve of smaller radius than the upper parts for this purpose. To separate the parts, it is only necessary to reverse the process.
From the above it will be seen that l have described and shown a fastening that can be used for a variety of purposes, although it is particularly adapted for fastening watch dials, and will be found to be neat, durable In testimony whereof I affix my signature, and convenient, and a much seeurer Inode of in presence of two Witnesses, this 29th day of Io fastening than any now in use. Merch, 1894.
