ATTACHING LINK FQR WRIST WATCH BRACELETS AND WATCH RINGS Filed Oct. 1, 1934 ATTORNEY.

Patented Apr. 30, 1935 1,999,707 A TTACHING LINK FOR WRIST WATCH BRACELETS AND WATCH RINGS Benedict Spiegel, Cleveland, Ohio Application October 1, 1934, Serial No. 746,374

6 Claims.

My invention relates to watch bracelet links, watch rings and the like and means for attaching same to wrist or pocket watches.

One object is to provide a simple device for attaching links or rings to Watches of either the wrist or pocket type.

Another object is to provide a novel locking means after the link or ring is attached to the watch.

Other objects and advantages may be noted from the following specification and its accompanying illustrations, in which:

Fig. 1 is a fragmentary view of a wrist watch and one form of locking link.

Fig. 2 is a sectional view of Fig. 1 with one side of link in released position.

Fig. 3 is a fragmentary view of a wrist watch with a modified form of locking link.

Fig. l is a sectional view of Fig. 3 with one side of link in released position.

Fig. 5 is a second modification of a locking link in locked position.

Fig. 5a is a fragmentary view of the form shown in Fig. 5, with the arms drawn together for releasing the watch.

Fig. 6 is a detail of the same, showing the open link before the sleeve is attached.

Fig. 7 shows a third modification in ring form applicable to a pocket watch and in locked position.

Fig. 8 is a top plan View of Fig. 7.

Fig. 9 is a view of the locking ring of Fig. 7 in unlocked position.

Again referring to the drawing: A wrist watch II! has a detachable locking link ll comprising a pair of arms l2 and i3 pivotally attached at one end to a bar M by pivot pins l5 and I6 and having locking pins H and I8 projecting at an angle from the opposite ends of said arms 12 and i 3 respectively, said locking pins being inserted through apertures i9 and 20 in a tubular bar 2 l. A spring 22 is located between the arms l2 and I3 within said tubular bar 2|, and thus as the arms l2 and [3 are pressed inwardly, the locking pins I1 and I8 are drawn inward within said tubular bar, the spring 22 being compressed between said arms l2 and I3, and the tubular bar 2! is then inserted between the projecting lugs 23 and 24 and the pressure on arms l2 and I3 is removed, this relieves the spring tension and locking pins '5 and I3 enter small apertures (not shown) in said lugs 23 and 24 and secure the link to said watch [0.

The modification shown in Figs. 3 and 4 is similar in action to that described above, except that it has projections 36 and 3| on arms 32 and 33 which have V shaped grooves 30a and 3m into which the finger nails may press thus compressing the arms 32 and pivotally attached to frame 34 of the link by means of pins 35 and 5 36. The arms 32 and 33 are also provided with locking pins 37 and 33 at the opposite ends slidably mounted within a tubular bar 39 and also having a spring 40 centrally located between said pivoting arms 32 and 33 to swing them out.

In the modification shown in Figs. 5, 5a. and 6 slightly different action and construction is shown, a bar having fiat circular split lugs 45 and d! at opposite ends, a pair of arms 48 and d9 being pivotally secured therein by means of screw pins 50 and 5| inserted through both split lugs and arms. Left and right threaded projections 52 and 53 extend inwardly from arms 48 and 49 respectively, and a sleeve 54 is threaded left and right to receive said projections and when screwed one way draws arms 68 and 49 together as shown in Fig. 5a and when screwed the opposite way spreads the arms 48 and 49 as shown in Fig. 5, the locking pins 55 and 56 engaging in lugs 23 and 24 in the same manner as the looking pins in the other type of link.

The modification shown in Figs. 7, 8 and 9 are of the ring type for pocket watch and are similar in action to Figs. 5, 5a and 6 except that one pivot 60 is used in place of the two used in the other types to pivot the half rings 6| and 62. The same type of locking bar is used as that in Figs. 5, 5a and 6 with threaded projections 63 and 64 from half rings 6i and 62 respectively and looking sleeve 65.

It will be seen that in any one of the constructions the swinging arms may be swung to engage or release the projections from the watch or other part to which the link is applied. In some of the forms the spring retains the link in engagement. In others, the threaded sleeve produces a similar result.

I claim:

1. An attaching link for the purpose described, comprising a bar, a pair of arms pivoted at one 45 end to the bar and adapted to swing toward or from each other and having lugs at the other end,

a tubular bar extending between the arms, and

a spring in the bar, pressing against the arms to swing the same from each other and engage the 50 lugs with a watch or the like.

2. An attaching link for the purpose described, comprising a bar, a pair of opposite arms pivoted at one end to the ends of the bar, a tubular bar between the other ends or the arms, and a spring 55 confined in the tubular bar and pressing the arms apart, the arms having lugs adapted to engage a watch or the like when pressed apart.

3. An attaching link for the purpose described, comprising a frame having a tubular cross bar at one end, a pair of arms pivoted at one end to the frame and having lugs at the other end adapted to engage in sockets in a watch or the like, and a spring confined in the tubular bar between the arms and acting to press the arms apart.

4:. An attaching link as in claim 3, the arms also having projections to receive finger pressure to swing the arms toward each other to release the lugs.

5. An attaching link for watches and the like, comprising a bar, a pair of arms pivoted at one end to said bar and having inwardly projected threaded studs, and a threaded sleeve connecting the studs, to swing the arms toward or from each other.

6. An attaching link for the purpose described, comprising a pair of arms, a bar to which the inner ends of the arms are pivotally connected in spaced relation, said arms having lugs mounted on the outer ends adapted to engage a watch casing or the like and means to swing the arms to so engage the watch casing.
