Said lower bar in Fig. 6 of the drawings of this specification. midway of the length thereofis provided with The clamp-lever may, however, be formed of the cam-like portion 5, which I designate as 5 a piece of sheet metal or of alight casting, as the frame-cam and which projects a short illustrated in Figs. 1, 2, and 3 of this specificadistance, substantially as shown, from theline tion.

The degree of said resistance may be regulated by properly graduating the proportions of cam 5 and the cam-bearing 6.

The opening movement of the clam p-lever from the position shown in Fig. 2 to that shown in Fig. 3 acts to spring or distort the lever, as will be understood by comparison of the positions in said figure of said lever relatively to the bearing-arm 7, which arm, together with the end portions of the clamp-bar E, constitute in effect torsion-springs for maintaining the proper action of the buckle and in connection with said cam-arm 5 to yieldingly lock the clamp-lever closed.

The operation of my improved buckle will be understood from the drawings, in connection with the preceding description. When the buckle is opened,as in Fig. 3, the-suspender-Web may be slipped into place in the usual manner and held therein by closing the clamp-bar to the position shown in Fig. 2. When it is required to release the web, the user, seizing the lever L, forcibly swings the said lever from the position shown in Fig. 2 to the position shown in Fig. 3, in which latter position said frame-cam stands in substantially its dead-center position, wherein it will remain until further moved by hand or closed.
