,SUSPENDER-BUCKLE.

SPECIFICATION forming part of Letters Patent No. 474,599, dated May 10, 1892.

Application filed November 4, 1891. serial No. 410,314. (No model.)

To aZZ whom it may concern:

Be it known that I, JOSEPH FRITZ, a citizen of the United States, residing at Baltimore city,in the State of Maryland, have invented certain new and useful Improvements in Suspender-Buckles, of which the following is a specification.

This invention relates to an improvement in suspenderbuckles; and the object is to provide a buckle which in its use will not tear the suspenderwebbing and which cannot loosen its hold on said webbing until manipulated in the proper manner.

To this end the invention may be said to consist in the novel features of construction and combinations of parts hereinafter described and claimed.

In theaccompanying drawings, which illustrate my invention, Figure 1 is a front View of the buckle. Fig. 2 is a rear View. Fig. 3 is a side or edge View. Fig. 4 is asimilar view showing the position of the parts when the buckle is released from the webbing. Fig. 5 is a vertical section showing the suspender-webbing clamped by The buckle, and Fig. 6 is a cross-section on line 6 6 of Fig. 1.

The device comprises a triangular plate A, having one edge turned up and serrated, as shown at a, and an inturnedear Z) at each end of said flange. A rectangular wire frame or bail B is hinged to the plate as follows: A side bar 0 of the frame extends across the plate below the teeth a and passes through the ears I), in which it may turn. The central part c of this bar is bent inward, so that it may be brought close to the plate. The end pieces (1 of the frame have position on 1 the outer side of the ears b,and between them and the bar 0 elongated loops 6 are formed out of the frame-wire, which loops extend at right angles to the said bar 0 and constitute cranks for turning the frame on its pivots, as will hereinafter appear. These loops extend on a downward angle to the side pieces of the frame and work close to the earslb. Their lower ends receive inturned trunnionsf of a wire frame C, the side pieces or wires 7) of which extend downward and converge. They come together at the lower part of the triangular plate A and thence extend downward side by side and are together turned or bent up to form a hook D, which takes the ring E and bent downward to extend behind the end of the hook for the purpose of holding the ring of the suspender-end in the hook, and this tongue is of sufficient length to allow a sliding movement of the frame 0 over the face of the plate.

In the use of the buckle the hinged frame Bis turned down to the position shown 111 Fig. 4 and the suspender-webbing F is introduced between the teeth a and the centralinbent portion of the bar 0. The frame is then turned up against the webbing, and 1t will be seen that the inbentportion 0 will be forced against the webbing of the suspenderand w ll bind the same down over the teeth a, (see F1g. 5,) whereby it is securely held. In this operation of the buckle the portion 0 of the frame serves as a rock-bar, the upper portion of the frame constituting a handle by which it is turned. This rock-bar, by reason of its bent central part, behaves like an eccentric or cam to bind the webbing over the teeth of the plate. It will be observed that the swinging down of the frame B causes the sliding up of the frame G by reason of the crankloops e being raised by the turning of the bar 0. Hence it will be apparent that a downward pull on said frame 0, acting on said crank-loops, will draw the hinged frame 13 to its upright position and turn the binding-bar a, so as to force its central part 0 against the suspender-webbing. Thuswith the suspenders applied the buckle can never release accidentally from the webbing, for there is always a downward strain on thehook through the ring E of the suspender-end. The downward angle of the crank-loops assists this binding function of the bar 0 because it keeps the trunnions f always at the outer extremity of said loops, whereby the greatest leverage is obtained. By arranging for the toothplate to remain stationary I avoid the tearing of the webbing incident to the use of a hinged tooth-plate.

a rock-bar extendinglengthwise ofsaid plate and journaled in the inturned ears, the central part of said rock-bar bent and forminga cam and the bar having cranks on its ends and a suitable handle for turning it, and a depending frame jointed to said'cranks and constructed to connect with a suspender-end 2. A suspender-buckle comprising -a plate having a toothed flange along one edge and inturned ears at opposite ends of said flange, a hinged frame one side of which constitutes a rock-bar extending lengthwise of saidplate and journaled in the inturned ears, the central part of said rock-barbent and forminga cam and the frame having crank-loops at the opposite ends of the rock-bar, and a depending frame having trunnions engaging in the ends of said crank loops and constructed to connect with a suspender-end.

8. A Suspender-buckle comprising a plate having a toothed flange along one edge and inturned ears at opposite ends of said flange, a rock-bar extending lengthwise of said plate and journaled in the inturned ears, the central part of said rock-bar bent and forminga cam and the bar having cranks on its ends and a suitable handle for turning it, and a depending frame jointed to said cranks, two side pieces of said frame brought together to form a hook and held together by portions of the plate bent over them, a portion of said plate also forming a spring-tongue extending past the end of the hook, for the purpose described.

In testimony whereof I affixmy signature in the presence of two witnesses.
