SPECIFICATION forming part of Letters Patent No. 733,248, dated July 7, 1903.

Application filed December 16, 1902. Serial No. 135,315. (No model.)

T0 aZZ whom it may concern.-

Be it known that I, JAMEs E. MITCHELL, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have made a certain new and useful Invention in Buckles; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference beinghad to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure l is a perspective view of my buckle as applied. Fig. 2 is a top plan view of the buckle. Fig. 3 is a bottom plan view of the same. Fig. etis a central longitudinal section of the buckle as applied.

This invention has relation to buckles, and has for its object the provision of a practical and efficient buckle all parts of which may be integral or in one piece and which has no movable parts whatever.

With this object in view the invention consists in the novel construction and combinations of parts, all as hereinafter described, and pointed out in the appended claims.

Referring to the accompanying drawings, the letterA designates the buckle-frame, comprising the front bar 13, the rear bar 0, and the side bars D. The front frame-bar B has its lower face 1) in the same plane as the lower faces of the side bars D, and its rear face I) has an inward inclination in such wise as to form an acute or sharp binding edge b at the junction of such rear and lower faces. Crossing the buckle-frame, adjacent to said front frame-bar, is the transverse pressure or fulcrum bar E, an interval e being left between said fulcrum and front bars of sufficient width to receive the strapF in a close manner. The barE has its lower face in the same plane as that of the bar B and is of such comparatively thin character that its upper face will be depressed considerably below the upper faces of the front and side bars of the frame.

In use the end portion of the strap is inserted in the slot or interval between bars 13 and E from below and passes over bar E to the rear or keeper bar 0 of the frame, under which it passes, the attached end portion of the strap being secured around an intermediate barfin the usual manner. The keeperbar 0 is usually formed with an oblique inner face on, the lower edge n of which is designed to bite on the end of the strap. In this way the thickness of the strap is received inv the frame-depression above bar E, and when the strain is put upon the strap it will bear upon the thin forward edge of bar E as a fulcrum to throw the strap directly or with a pressure of a direct character against the binding edge 19 of the frame-bar B in such manner as to prevent any give or with drawal of the strap whatever, a positive bind being effected without the addition of any further securing means-such as an additional turn of the strap,locking-teeth,prongs or tongues, &c.-perforation and marring of the end portion of the strap being entirely avoided. The keeper-bar 0 serves to confine the loose end of the strap in a positive manner, thereby holding the leverage at the edge of the transverse fulcrum-bar E. The slot e is narrow, being about equal in its interval to the thickness of the strap. The interval is wedge form, the opposite faces of the bars 13 and E being beveled in such wise that the opening of the interval or slot in the under side of the buckle is its narrowest portion, and the strap is designed to neatly engage the acute edges of these bars. The side bars being comparatively thick with reference to the fulcrum-bar, the strap end is held between them in a guarded manner and so as to provide a finished appearance when in use.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent,is

1. The buckle consisting integrally of the side bars, keeper-bar, beveled front bar, attachment-bar, the thin fulcrum-bar considerably depressed below the upper edges of the front and side bars, said buckle having the wedge-form slot between the front bar and the fulcrum-bar, substantially as specified.

2. The buckle, consisting of the side bars, the rear keeper-bar, the intermediate attachment-bar, the thick front bar, having an in wardly-inclined rear face, and an acute binding edge at the junction of said inner face ICO and the lower face of said bar, the thin bevness of the attached strap, substantially as \o eled fulcrum-bar, adjacent to said front bar, specified.

and having its lower face in the plane of the In testimony whereof I affix my signature lower face of the front bar, and its upper face I in presence of two Witnesses.

depressed considerably below the level of i the upper edges of said front and side bars, JAMES MITCHELL said buckle having between the fulcru rn-bar and the front bar the wedge-form slot, whose interval or space is about equal to the thick- \Vitnesses;
