srnrne RING.

Application filed October 5, 1921. Serial No. 505,649.

To all whom it m my concern Be it known that I, EDWIN L. RomNsoN, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Spring Ring, of which the following is a specification.

Prior to my invention hereinafter described spring-rings were commonly formed in one of the following ways. One of the methods was to insert a wire in the bore of a tube to prevent the tube from being distorted in bending. The tube was then wound around an arbor into ring form. The ends of the bent-up tube were not united but were left a distance apart. The inserted wire was then eaten out by acid so as to clear the bore of the tube. Another wire was then inserted in one end of the bore of the ring and arranged to slide therein to open and close the space between the separated ends of the ring. The outer end of said wire was enlarged or provided with an enlargement adapted to abut against the opposite end of the tube and serve as a stop to further movement of the slide in either direction.

Another common way of forming the spring-ring was to form the ring in the same manner as already described, but with the tubular section shorter and to solder in the bore at one end a solid wire of less diameter than the tubular section, and another wire was inserted in the bore of the opposite end of the tubular section of the ring and arranged to slide therein and to abut against the free end of the wire section of the ring to close the opening between the bored and solid end of the ring.

Both of these modes of forming a springring involved many operations and added considerably to the expense of manufacture.

The purpose of my invention is to provide a spring-ring of few parts and which in its construction will not require the use of solder or the insertion in and subsequent re moval from the tube of the form-preserving wire heretofore necessarily employed to prevent distortion of the tube in bending it into ring-shape.

To these ends my invention consists in the novel and useful construction, combination and arrangement of parts hereinafter de- Like reference letters and numerals indi I cate like parts where they occur in the drawlngs.

In the drawings 1 represents the tubular body of my spring-ring. 1 represents the portion having the larger cross-section and 1 the portion of reduced crosssection. The bore in the portion 1 being consequently of greater diameter than that in the portion 1 I term it the larger bore. 2 represents the slidable member operating in saidlarger bore of the body member and arranged and adapted to open and close the space between the ends of the latter. 3 represents a spring seated in the larger bore and controlling the movements of the slidable member 2.

(Fig. 2.)

The body member 1 is bent on an arbor into ring shape with its ends spaced a distance apart. (Fig. 6.) It is'then by dies swaged so that for a portion of its extent it will be of shorter cross-section than the other portion, the bore of the two portions of the body being similarly unequal. (Fig. 6.) To the edge of the body member is attached the well known form of ring 4 for connecting the spring-ring to a chain or the like. The member 2 is of the same diameter as the reduced portion of the body member and abuts against it when closing the opening between the ends of the body member.

It will thus be seen that I have produced a new andnseful spring-ring having an integral body member a portion of which is of. reduced cross-section, the portion having the larger cross-section fitted to receive the slidable member and its controlling spring, and the portion having the reduced cross-section fitted to serve as an abutment for the slidable member when the latter closes the opening between the ends of the body member. Furthermore I am by my invention able to dispense with the form-preserving wire heretofore necessarily inserted in the bore of the tube to prevent distortion of the latter in bending it into ring shape, and I am able to dispense with solder or other means heretofore necessarily employed to secure together the parts of a spring-ring constructed with a tubular and a non-tubular portion.

1 claim as my invention and desire to secure by Letters Patent:

1. spring-ring comprising an integral tubular body member of reduced cross-section for a portion of its extent, whereby the bore in one portion of said member will be of greater diameter than that in the other portion, said bodyinember bent into ringshape with its ends alined and spaced a distance apart, a spring operatively seated in said bore of the greater diameter, and a member slidably fitted in said bore, and actuated in one direction by said spring to close the opening between said body ends, and operative in the opposite direction against said spring to uncover said opening.

2. In a spring-ring a one-piece tubular body member having one portion of its length of greater diameter than the other portion, said body member bent into ringshape with its ends alined with each other and spaced a distance apart in combination With a plunger reciprocatingly fitted in the larger end of said body member and arranged to cover and uncover at will the open space between the ends of said body member and a spring seated in said larger end and controlling the movement of said plunger.

3. In a spring-ring a onepiece tubular body member bent into ring shape with its ends alined with each other and spaced 9.

distance apart, one portion of said body member being of greater diameter than the other portion whereby said larger portion is arranged. and adapted to slidably receive a reciprocating plunger covering and uncovering at Will the open space between the ends of said body member, and the smaller portion of said bOdy member adapted to serve as a stop limiting the movement of said plunger in closing said open space.
