I This invention relates to a swivel; for one of its objects the provision of 2.

Claims.

and has construction which will be much simpler to form than the constructions which are usually offered on the market.

' Another object of the invention is the provision of a swivel which will be formed of fewer parts and yet be a stronger construction whereby less assembly operations are necessary and the liability of the separation of the parts be minimized.

al of the Another object of the invention is the formation of a guide and retaining means for a wire spring in the swivel.

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 out in the appended claims.

In the accompanying drawing:

In the formation of swivels of this general character it is usual to provide an arm at the end of the bow which is partly severed just prior to bending and a tube is soldered in the severed portion at which tube receives a pivot pin which the gap of the partly severed portion,

isaninture requires many tions, some of which by highly skilled workmen with the co labor and assembly operaare required to be performed rresponding expense of construction, all of which may be much lessened by the structure which I provide wherein a part of the end wall of the body is utilized as the pivot bar and the end of the bow which forms the tongue is merely bent around this bar to provide its pivotal mounting; and I have extended the other end of the bow which is soldered to the body toward this pivot so that it not only forms the function of preventing the entrance of shot into the body but also serves by reason of a slot herein as an effective guide and positioning structure for the resilient spring; and the following is a more detailed description of the present embodiment of this invention, illustrating the preferred means by which these advantageous results may be accomplished:

With reference to the drawing, Ill designates a hollow generally tubular formation of body with somewhat conical side walls II and end wall l2 which end wall is provided with a slot or open ing 13 and a second smaller slot or opening l4 spaced therefrom to provide a pivot or bar portion [5 between the slots [3 and M.

The other parts of this swivel are formed from a blank l6, shown generally in Fig. 6, which has a pair of arms ll formed at one end with a slot l8 between them, while its other end is formed thinner as at 19 to be easily rolled into an eye or loop formation. This is also grooved as at 20 in an alignment with the slot l8.

This blank is bent up into a bow form 2|, as shown in Fig, 7, with a hook portion 22 which is threaded inwardly through the opening l3 so as to receive the bar [5 within the space 23 of this hook after which the hook is closed about the bar I5, as shown in Fig. 3, so that its end portion 24 is brought snugly against and within the shoulder 25, as shown in Fig. 3, to provide a closed loop about the bar I5 and yet one which is sufiiciently loose so that the same may rock about the bar as a pivot. The opposite end of the bow 26 with its arms I! is then inserted into the opening l3 with its notch 21 in engagement with the edge 28 of this opening and its arms I! extending toward the pivot bar 15 so as to substantially close the entrance to the hollow body 10 and prevent the entrance of tumbling shot therein where it is soldered in place.

A spring of generally U-shaped formation and designated 29 is then slipped in place in the tends into the hollow body H3. The end 3! engages near the end of the slot 28 so as to be outwardly of the pivot.

The tongue is then formed by severing the bow along the line 3d at an angle so that the ends and thus formed will provide a stop to prevent the outward swinging movement of the tongue 33 beyond the position shown in Fig. 2, although allowing inward movement to the position shown in Fig. 3, by compression of the spring to permit some loop or other to be inserted into the bow for holding the same in position.

The stud portion 37; of the body receives a collar 33 and is headed over as at 39 to provide a shoulder and prevent the escape of the collar, which collar has attached thereto the ring 40 soldered at one end and inserted in the opening M at a diametrically opposite location in a usual formation for attaching it to some desired object.

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:

i. A connector comprising a seamless hollow body provided with an end wall having spaced openings to provide an integral pivot bar, a bow secured to said body, a tongue cooperating with said bow and having a portion embracing said pivot bar to rockably mount the tongue thereon, and a spring within the body and having one end portion extending outwardly and engaging said tongue outside of said body to swing the tongue toward the bow.

2. A connector comprising a seamless hollow body provided with an end wall having spaced openings to provide an integral pivot bar, one of said openings receiving therethrough a bow which is fixed to the body, a tongue embracing said pivot bar to rockably mount the tongue there on, and also a spring contacting and acting to relatively urge said bow and tongue in opposite directions.

3. A connector comprising a seamless hollow body provided with an end wall having spaced openings to provide an integral pivot bar, one of said openings receiving therethrough a bow which is fixed to the body, a tongue embracing said pivot bar to rockably mount the tongue thereon, and arms on said bow extending toward said tongue to close said opening to the body through which said bow extends.

i. A connector comprising a seamless hollow body provided with an end wall having spaced openings to provide an integral pivot bar, one of said openings receiving therethrough a bow which is fixed to the body, a tongue embracing said pivot bar to rockably mount the tongue thereon, a spring contacting and acting to relatively urge said bow and tongue in opposite directions, and arms fixed on the bow adjacent the body and located on either side of said spring and extending toward said tongue to close the said opening to the body through which said bow extends.
