Referring now more particularly to the drawing, the buckle of this invention comprises a member In having a cross bar H, and a pair of arms l2 and I3 having pivot loops l4 and H5, respectively. The member ID is preferably formed from a single piece of round wire initially of uniform diameter and subsequently preferably flattened in portions to obtain a desired rigidity and pleasing appearance. An intermediate portion of the wire strip forms the cross bar H and the ends are bent at right angles thereto and inwardly toward each other in a spaced relation with the cross bar H to form a substantially rectangular slot IS, the extreme ends being bent again at right angles outwardly and into the loops Hi and IS.

A second member I1 is pivotally mounted in the member H in the loops l4 and I5, the second member preferably being formed of a single continuous piece of round wire of smaller diameter than the diameter of the wire of the first member H). An intermediate portion of the wire is formed into a button-receiving loop ill, the entrance to the loop being of lesser width than the diameter of the loop to prevent accidental disengagement of the button from the button-receiving loop.

Portions of the wire adjacent to the loop I8 are bent in a direction away from each other and are thereafter directed inwardly toward each other to form loops IS, the width between the loops being sufficiently wide to permit the entrance of a strap 30. Portions 2i) and 2! of the wire of the member I! extending from the loops it are formed substantially parallel with the cross bar H to be received in the loops l4 and i5 respectively, these portions 2!! and 2| being slidable in the loops in the direction of the axes thereof.

Prongs 22 and 23 are preferably formed integrally with and extend substantially at right angles to the portions 20 and 2| respectively of the member H in a direction toward the cross bar ii, the ends of the prongs being movable between a position against and a position spaced from the cross bar H as the members l0 and H are pivoted relatively. Since the prongs 22 and 23 must ordinarily penetrate through the material of the strap, belt, or the like, that is, where openings are not provided in the straps, it is desirable for these prongs to be pointed and sharp.

In order to lock the ends of the prongs 22 and 23 against the cross bar H to prevent casual relative movement of the members is and I1 and to guard against accidental misuse of the sharp prongs, the cross bar H is provided with a locking means for releasably enclosing the pointed ends of the prongs. Such locking means are shown in the drawing as cars 24 and 25 whichare preferably formed integrally with or are otherwise secured to the cross bar ll.

Referring more particularly to Fig. 2 of the drawing, the cross bar H is shown as being flattened at the portions 26 and 21 with the material thereof being displaced to provide a seat against which the prongs rest in a normal position of use. Portions of the material of the cross bar ll adjacent the seats 26 and 21 are further flattened to form the ears 2 3 and 25 which are preferably substantially narrower than the width of the seats 26 and 2'! which, when the ears are bent over, present pockets, the ears extending in a spaced substantially parallel relation with the flattened portions or seats 26 and 21. width of the ears, being narrower than the seats, forms notches 28 and 29 for permitting entry of the prongs into the pockets beneath the ears, the thickness of the normal cross section of the cross bar H being preferably substantially as great as the overall cross section at the ears.

The illustration of Fig. 5 in full lines shows the prongs 22 and 23 locked in position against the cross bar H by the ears 24 and 25 which are preferably formed integrally therewith. When it is desired to release the prongs from their locked position, loop portions IQ of the frame I! are urged in a direction of movement toward each other so that the ends of the prongs may be aligned with the notches 28 and 29 adjacent the ears 24 and 25 as shown in dotted lines, and. the member Il may thereafter be pivoted in the lops l4 and is so that the prongs may be moved to a position spaced from the cross bar. This movement of the prongs is permissible by reason of the member I! being resilient, the frame being made of comparatively light wire having a substantially wide loop for receiving the button of the bib of the overall.

The strap 30 of an overall may be inserted through the opening l6 when the prongs are spaced from the cross bar H, whereafter the prongs pierce the shoulder strap and the end of the strap is directed through the second member between the loops i9 therein to fall downwardly behind the bib 3! of the overall. After the strap has been pierced by the prongs the member I1 is pivoted in a direction such that the prongs move toward the cross bar. During this movement the loop portions IQ of the member ll are moved toward each other in the direction of the axes of the loops so that the prongs 22 and 23 are in alignment respectively with the notches 28 and 29 opening into the pockets formed by the ears 24 and 25.

The movement of the prongs 22 and 23 inwardly toward each other may be limited so as to predetermine the position of the prongs with respect to the notches by means of angular bends 32 and 33 adjacent the portions 20 and 21 respectively of the member ll. After the ends of the prongs 22 and 23 are received in the notches, pressure is released from the loops l9 and the prongs return to an initial normal position of use by reason of the resiliency of the member [1.

While but a single embodiment of this invention is herein shown and described, it is to be understood that various modifications thereof may be apparent to those skilled in the art without departing from the spirit and scope of this invention and therefore the same is only to be limited by the scope of the prior art and the appended claims.
