Patented Oct. 11, 1938 UNITED STATES PATENT OFFICE SWIVEL CONNECTER William A. H. Wells, Edgewood, It. I. Application May 22, 1937, Serial No. 144,193

6 Claims.

This invention relates to a connecting device, particularly of the character used on the end of a watch chain or the like for connecting the chain to the ring in the stem of-a watch, and is some- 5 times referred to as a swivel; and has for one of its objects the construction of such a device which will efiectively prevent the removal of the spring actuated tongue when the parts are in assembled position.

1 Another object of the invention is the provision of means to prevent the twisting of the tongue about a longitudinal axis through the tongue and thus prevent the wings which extend beneath the end wall of the body of the connecter from being so disposed that they may be removed through the opening in the end wall of the connecter.

Another object of the invention is to form a guide for the directing of the spring which urges the tongue toward one extreme of its position in place.

Another advantageous feature of the invention which is incidental to the objects thereof is to prevent shot which may be used for the tubing of the connecter from getting into the hollow body of the connecter.

With these and. other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and'particularly pointed outin the appended claims.

In the accompanying drawing:

Fig. 1 is an elevation of the connecter finished;

Fig. 2 is a central sectional view thereof with the tongue in closed position;

. Fig. 3 is a view similar to Fig. 2 of the tongue in open position;

Fig. 4 is a sectional view on line 4-4 of Fig. 2;

Fig. 5 is a sectional view on line 5P5 of Fig. 3 showing only the tongue and the fingers and their relationship on the end of the hook;

Fig. 6 is a sectional view of the hollow body of the connecter;

Fig. 7 is an end view of the body of the connecter;

Fig. 8 is a top plan view of the shank and tongue in one stage of their formation;

Fig. 9 is a central sectional view of the structure shown in Fig. 8.

In the use of connecting devices of the character here shown, often referred to as swivels, it frequently occurs that thetongue which is spring pressed to closed position becomes twisted permitting removal of the tongue from the opening in the hollow body, and it is known that if the swivel be struck in a certain manner the tongue will often be displaced; and in order to avoid this resuit I have provided a pair of fingers on the end of the shank of the hook which extends into the body to effectively prevent the twisting of the tongue and removal thereof, and also these fingers serve the advantageous purpose of providing a 5 guide for the insertion of the spring in place while also preventing fine shot which is used in the tubing of these devices from entering the connecter to clog up its operation; and the following is a 3 more detailed description of the present embodim mentof this invention, illustrating the'preferred means by which these advantageous results may be accomplished:

With reference to the drawing, [0 designates the hollow body 'of the device which is provided with an end wall ll having an opening l2 therein of the shape shown in Fig. 7. A stud I 3 extends from the body to receive a swivel collar l4 which may rotate thereabout and is held in position by the riveting over or heading l5 of this stud I 3. A ring I6 is rockably mounted in a bearing I! in the swivel collar I4, it being bent into abutting relation with the collar as at l8 at the diametrically opposite portion of this collar. The shank and tongue are first fashioned in a single piece 20, as shown in Figs. 8 and 9. By a suitable striking or pressing operation wings 2| are formed at one end of the bar 20 by providing a suitable cup 22 therein to spread the stock in the desired manner. The other end 23 of the bar 20 is formed bifurcated by providing the slot 24 and I bend the fingers 25 at either side of the slot laterally or at right angles to the bar, as shown in Fig. 9, prior to the bending of the bar 20 into generally the shape of a loop, as illustrated in Figs. 1 and'2.

After the bar is bent into the loop shape indicated and forming the opening 26 the wings 2| are inserted through the opening l2 by disposing them longitudinally of this opening and then the loop-shaped bar 20' is rocked through to dispose the wings beneath the end walls ll of the hollow body and the other end of the bar, comprising the laterally extending fingers 25, are inserted through the opening, and this last inserted portion of the bar is soldered in position as at 21, shown in Figs. 2 and 3.

The spring 28, shown in Figs. 2 and 3, is then positioned in the slot 24 between the fingers 25 by inserting the bent portion 29 thereof into the position shown having the one arm 30 in a recess 3| between the fingers with its end adjacent the abutment 32 formed by this recess, while the other end or arm 33 is disposed within the recess 34 JJI ' concave surface 43 of the body portion of the device and is guided by the edges of the opening I2 in the end wall ll of the body. 7 I

The foregoing description is directed solely towards the construction illustrated, but ,I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.

I claim; s
