WATCHBAND CONNECTING MEANS Filed Nov. 12, 1954 m I /M/ 1 IMF IN V EN TOR. Trdw GM BY al/(m United States Patent WATCHBAND CONNECTING MEANS Tobias Garon, Detroit, Mich.

Application November 12, 1954, Serial No. 468,361

1 Claim. (Cl. 24-265) Be it known that the undersigned has invented new and useful improvements in watchband connecting means of which the following is a specification.

This application relates to watchband connecting means and particularly to means for connecting the loop of a narrow watchband to widely spaced lugs of a watch.

Jewelers otter desire to connect the loop of a watchband to spaced lugs of a Watch where the watchband is considerably narrower than the space between the lugs. In this application means are shown which enable the jeweler properly to connect and fit the loop of a narrow watchband to more widely spaced lugs of a watch.

The invention has been embodied in a device shown in the appended drawing.

In this drawing:

Fig. l is a fragmentary view of a watch having widely spaced lugs with a narrow watchband connected to it by the embodiment of the invention disclosed.

Fig. 2 is a sectional view of one embodiment of the invention per se.

Fig. 3 is a fragmentary cross-section view as if on line 3-3 of Fig. 1.

Referring to the drawing it will be observed that the same shows a conventional watch having widely spaced lugs 11 each containing a hole 12 for receiving a means for connecting the loop 14 of a watchband 15 between and to a pair of lugs.

In its basic form the means comprises adapters 20, one for each end of the loop 14 and for each lug 11. Each adapter comprises a tube 21 having one end 22 provided with a small diameter opening 23. Inside the tube 21 is a coiled compression spring 24 and telescoped within such spring is a pin 25 having a pin end 26 projecting through the tube opening 23 and having a head 27 inside the tube 21 between the ends of the spring 24 and the tube 21 for limiting outward movement of the pin end 26 under pressure from the spring 24.

With two such adapters in the opposite ends of the loop 14- of a narrow watchband 15, proper fitting and connection can be made between the band loop 14 and the lugs 11 with the projecting pin ends 26 seated in the lug holes 12 and retained there by the springs 24.

For improving the appearance and the fit of the band in the lugs each tube 21 is surrounded by a ring 28 secured to the tube 21 at the end 22, such ring providing a stop shoulder for each adapter engaging an end of the loop 14.

The width b of such ring 28 takes up the distance /2 (c-a) where c is the wide space between the lugs 11 and where a is the narrow width of the band loop 14.

For commercial purposes it is contemplated to make the 2,791.,0'18 Patented May 7, 1957 ice '2 ring 28 with a dimension b /32 inch in one size and A inch in a second size. The maller size, used ina pair, adds A inch to the width of the band loop and thus fits a inch band to an inch spacing between the watch lugs, and fits a inch band to inch space. The larger size adapter, where b equals inch, when used in pairs, fits a /8 inch band to a /1 inch space and a inch band to a /8 inch space. The device is simple and easy to use and when used creates an appearance for the connection substantially the same as would be obtained if a band were used with a watch whose lugs were spaced the same as the band width, and where the connection is established through the conventional double end spring pin.

Inasmuch as the lug holes 12, in many cases, are blind holes, and inasmuch as it is necessary to enable the adapters to be manipulated to pull the pin ends 26 out of the holes 12 to release the band from the watch, the tube 21 of each adapter is formed at its opposite end 32 with a small hole 33 and the pin 25 is extended to provide a second projecting end 36 and the latter is formed with a groove providing a shoulder 38 which may be engaged by a tool inserted through the opening 39 in the side of the loop 14 whereby such tool can engage such shoulder 38 and move the pin 25 in such a way as to remove its projecting end 26 from the blind hole 12 of the watch lug.

Now having described the embodiment herein disclosed, namely the means for connecting the loop of a narrow watchband to widely spaced lugs of a watch, reference should be had to the claim which follows.

I claim:

Means for connecting the loop of a narrow watch band to widely spaced lugs of a watch comprising two adapters, one for each end of the loop and for each lug, each adapter comprising a double ended tube having each end provided with a small opening, a coiled compression spring therein, a double ended unitary pin inside said tube and spring and having a pin end projecting through each tube end opening and having a head inside the tube near one end thereof between that tube end and an end of the spring for engaging the adjacent tube end and thus limiting movement of the pin under spring pressure, a ring surrounding and integrally and immovably secured to the tube at the end thereof adjacent the headed end of the pin, with the opposite end of the pin outside the tube having a shoulder defining groove, the two adapters being adapted to be positioned within the loop at opposite ends thereof, with the grooved pin ends adjacent, and with the ungrooved pin ends and the rings being outside the ends of the loop, the rings thus filling the space between the narrow watchband loop and the widely spaced watch lugs, these lugs receiving the ungrooved pin ends, the grooves being adapted to be engaged by a tool inserted into the loop at the center thereof to enable the tool to retract the pins from the watch lugs.
