Description

Patented lSept. 17, 1935 UNITED STATES PATENT OFFICE 3 Claims.

This invention relates to clasps particularly adapted for use in conjunction with garters or Suspenders for the support of garments.

The primary object of my invention is to provide a garment clasp composed of a minimum number of component parts, each part being of particularly simple formation so that it permits of extremely economical manufacture.

A further object of my invention is to provide a garment clasp in which the arrangement and construction of the parts permits their complete assembly entirely by hand without. the aid of any tools or machines.

Other objects and advantages of my invention will be apparent from an inspection of the drawing and the following description.

The invention will be fully and comprehensively understood from a consideration of the following detailed description when read in connection with the accompanying drawing which form part of the application, with the understanding, however, that the improvement is capable of extended application andY is not confined to the exact showing of the drawing nor to the precise construction described and, therefore., such changes and modifications may be made therein as do not affect the spirit of the invention nor exceed the scope thereof as expressed in the appended claims.

In the drawing:

Fig. 1 is a perspective View of my suspender clasp in use attached to a garment.

Fig. 2 is a composite perspective view of the component parts of my clasp disassembled from eachother. Y

Fig. 31 is a side elevational view of the clasp in closed position with one endof the loop thereof show-n inI section; and

Fig.. 4is a side elevational view similar to Fig.A 3

, with the clasp in open position.

Referring, now to the drawing for a more detailed description thereof and particularly to Fig. 2, my improved suspender clasp is composed only of the four partsl illustrated therein. Ihe letter A designates the front jaw member of my clasp, of which B designates the rear jaw member. The letter C indicates a loop by which the clasp it attached to a suspender web 5, as shown in Fig. 1. I'he three members A, B and C are all held together when properly assembled to each other by the insertion of a fiat pin D.

A detailed description of each of the parts now follows. The front jaw member A comprises a substantially dat plate 6 from the upper portion of which extend rearwardly vertical parallel side Walls l. The lower portion of plate 6 is flanged at its periphery for the purpose of strengthening the member, the bottom flange 8 extending beyond the side flanges so as to provide a claw at the lower edge of jaw A. The upper ends of the 5 vertical sides 'I are arcuately formed and have at their apexes a pair of notches 9 of semi-circular shape for the purpose hereinafter described. Each side wall 'l is further provided with apertures I@ in alignment with each other and which l0 are each of the form of a reversed L. The front surface is arcuately formed to terminate in a line with the forward edge of notches 9. From the upper portion of the plate 6 are extruded a pair of vertical ribs II, the interior recess thus l5 formed providing clearance for the member B when assembled.

The rear jaw member B comprises a plate I2, the lower portion of which is flanged, the bottom flange I3 thereof extending beyond the side 20 anges I'lI to form a claw which, in cooperation with the claw 8 of the front jaw grasps the garment. From the upper portion of plate I2 a pair of vertical parallel side walls I5 are integrally formed and of such spacing as to permit their 25 insertion between the side walls I of the front jaw A. The upper ends of side walls I5 are arcuately formed and are provided at their apexes with a pair of aligned trunnions I6 adapted to engage in the notches 9 of the front jaw A. 30l Trunnions i6 are of semi-circular cross-section to function as a pivot for the members A and B. 'I'he plate l2 extends upwardly and around in conformation to the curvature of the side walls I5 and terminates in alignment with the trunnions 3'5 I6. Side walls I5 are further provided with Valignedapertures I1, the shape of which resembles substantially an inverted L.. the vertical leg of which is disposed forwardly of the member B. l0

The loop C comprises ay longitudinal flat member 20,4 each end of which is formed in a return bend 2| fromV which depend in Vertical parallelism with each other a pair of ears 22. The ears 22 are each provided with oblong apertures 45 23 in alignment with each other and adapted to hold snugly the at pin designated by letter D. The pin D is provided at one end with an enlarged head 24. The ears 22 of the loop C are spaced from each other suciently to permit their place- 50 ment outside the side walls I of the front jaw A, as shown in Fig. l.

In the assembly of my clasp, members A and B are placed together so that the trunnions I6 of member B engage in the notches 9 of member 55 A. The lower ends of members A and B are then brought together, as shown in Fig. 3, after which the loop C is put in place with its ears 22 at the sides 1 of member A and with the apertures 23- thereof in alignment with the free area of the combined apertures I0 and I1. This co-relation of the apertures is shown in Fig. 3. The pin D is then inserted thru the apertures in members A, B and C, thus effecting the complete assembly of my garment clasp without the use of any tools or other equipment, in that the pin D ts snugly into the apertures 23 to prevent accidental removal of same.

Before taking up the operation of my clasp, that is, the opening and closing of same, it is well to note that the loop C in conjunction with the pin D functions as a bell crank to effect the separation of the jaw. A careful inspection of Figs. 3 and 4 will suffice to illustrate this function. In the opening of my clasp the loop C is swung from its vertical position, Fig. 3, to a substantia1- ly horizontal position, Fig. 4, during which movement the pin D moves from a horizontal position, Fig. 3, to a substantially vertical position, Fig. 4. A careful examination of the co-relation and shape of the apertures I0 and I1 will facilitate the clear understanding of the action of pin D during this movement. It is to be noted that the vertical legs of apertures li) extend upwardly, thus providing shoulders l0a on the interior of apertures I0. It is also to be noted that the vertical legs of apertures l1 extend downwardly, thus providing shoulders lla, on the interior of the apertures, which shoulders are disposed op positely to the shoulders Illa. During the opening of the jaws of the clasp and specifically as the pin D is rotated, diagonally opposite portions of the longitudinal faces of pin D become engaged with the shoulders I0a. and Ila, and as the rotation of pin D is effected, the corresponding movement of shoulders Ia and Ila in opposite directions is effected and thereby causes the angular separation of members A and B. It is worthy to note that during this separation the trunnions i6, in engagement with notches 9, function as a pivot to hold the upper ends of members A and B together.

To effect the closing of the clasp so as to securely grasp a garment, the loop C is swung from the position in Fig. 4 upwardly to the position shown in Fig. 3. The pin D is thus rotated in the apertures I0 and Il so that the edges of pin D engage with the forward Vertical edge of apertures Il and the rear vertical edge of apertures ID, thus causing members A and B to move toward each other to the position shown in Fig. 3. In that the edges of pin D t snugly between the outer vertical edges of apertures I0 and l1, the accidental rotation of loop C is prevented.

What is claimed as new and useful is:

A clasp comprising a pair of cooperating jaws pivotally connected together, each of said jaws comprising side walls, the side walls of one of said jaws having apertures of reversed L formation and the side walls of the other of said jaws having apertures of inverted L formation, a turnable key passing thru said apertures and adapted to open, close and lock said jaws, said apertures comprising horizontal and vertical portions, the horizontal portions of the apertures of one jaw being in registration with, and the vertical portions of the same being out of registration with, the corresponding portions of the apertures in the other jaw when the jaws are closed, said side Walls, due to the mentioned.
