Application filed May 3, 1915.

ToaZZ whom-it may concern Be it known that I, Mason B. FRANK-LIN, a citizen of the United States, residing in the city and county of Providence and State of Rhode Island, have invented a new and useful Guard-Pin for Surgical Bandages and the like, of which the following is a specification.

The purposes of my invention are to provide a one-piece pin for securing surgical bandages, garments and the like in which the pin point will be guarded and prevented from injuring the person, and also from undesirable unlocking, with provision of means for interlocking a number of the pins chain-like for the better securement of surgical bandages.

To these ends my invention consists in the new and useful construction, combination and arrangement of parts hereinafter described, and illustrated in the accompanying drawings, in which,

Figure 1 is a perspective view of pin. blank partly formed into a pin embodying my invention. Fig. 2 is a perspective view of my newly invented pin, without ornamentation. Fig. 3 is a front end elevation of Fig. 2. Fig. 4 is a perspective View of the fulcrum and spring end of my pin and its reinforcing member. Fig. 5 is a plan view of the under side of Fig. 4: with an ornamenting plate added, and the pintongue shown in section. Fig. 6 is a plan view of my pin fitted for union with a similar pin. Fig. 7 is a plan view of two of my pins united chain-like. Fig. 8 is a side elevation of Fig. 7.

Similar reference letters and numerals indicate like parts in all the views.

Referring to the drawings: 1 represents a wire, which, mediately of its length has been bent, first spirally or volutely to form a spring portion, as at 1 and then downward a distance, to form the heel 1 and further bent forward beneath and parallel with the upper member. Said lower portion is pointed at its forward end and constitutes the pin-tongue 1 in its completed state. The spiral at the heel 1 of the pin is pressed into practically a volute coil disposed in the plane of the upper member of the pin to thereby constitute both the spring and fulcrum of the pin-tongue. (Fig. 2). Said upper member is hereinafter referred to as the body of the pin. The forward end of said body is bent downward a dis- Specification of Letters Patent.

tance, curving backward to form a shoulder,

as at 1 thence in a series of curves returned and fastened upon said body to thereby form a catch for t e pin-tongue 1 as shown in Figs. 2 and 3. The described and illus tratedform of said catch 1 is such that the pin-tongue is guarded and is prevented from undesirable disengagement from the catch by the inturned loop of the catch which forms a hook, and by the shoulder 1 of the catch which tends to throw the pin end back into the hook 1. (Fig. 3). While the construction shown in Fig. 2 is sufliciently strong for ordinary use, it may for some purposes be advisable to strengthen it, and in such cases I provide a reinforcing member 2 which engages the heel 1 and extending forward a distance is sleeved upon the body of the pin, as shown in Figs. 4, 5 and 8. A similar plate 4: may be sleeved upon the opposite end of said body. (Figs. 6, 7 and 8.) For ornamental purposes a second plate 3 engages the downward extending portion of the said heel and is similarly sleeved upon said body. This last named plate may carry any desired ornamentation, and may serve as a setting for precious stones in cases where the pin is to be used as a garment or breast pin.

In Figs. 6 and 8 I have shown the body 1 of the pin bent backward to form a loop 1 in the plane of said body and in advance of the catch 1 thus affording means for connecting the pins in links or chain-like by in .serting the pin-tongue 1 through the loop 1 of another pin until the heel 1 of the foremost pin engages the loop 1 of the rearmost pin, as shown in Fig. 8, thus enabling a surgical bandage to be more firmly secured by a practically continuous chain of 7 pins.

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

1. A one-piece guard pin for securing surgical bandages and the like, consisting of a wire pointed at one end, and at its opposite end bent in a series of curves and returned upon itself to constitute a hookshaped pin-tongue catch disposed at right angles to said wire, a vo'lute coil located mediate the length of said wire in the plane of the latter and at right angles to the plane of said catch, a heel formed by the eXtension of the pointed end of said wire axially a distance parallel to said catch and at right angles to said coil, and a pin-tongue formed,

by turning said pointed end at right angles to said heel and forward to said catch.

2. A one piece guard pin for surgical bandages and the like, composed of a single Wire pointed at one end, and at its opposite end bent into a longitudinally directed loop disposed in the plane of said Wire, and rearward of said loop bent in a series of curves into a hook-shaped pin tongue catch disposed at right angles to said loop and Wire, a volute coil located mediate the length of said Wire in the plane of the latter and of said loop, a heel formed by the extension of said pointed end a distance beyond said coil and in the axial line of the latter, and a pin tongue formed by turning said pointed end at substantially a right angle to said heel and forward to said-catch, said loop arranged and adapted to receive the pin tongue of a similar pin and engage the heel thereof to unite the two pins end to end chain-like.
