BUCKLE.

Application filed .April 27, 1927. Serial No.` 186,922.

My invention relates to buckles and particularly to that type composed of two members, one member pivotally secured upon the other and one member designated as the tongue member, both members jointly operating to clamp between them the strap to which the buckle may be applied.

v My invention has for its object the manufacture of a buckle in which the parts composing it are preferably of cast metal and co-operate to hold a strap, with which the buckle is adapted to Vbe used, by clamping' the strap at both ends of the buckle.

Referring to the drawings in which similar numerals indicate identical parts- Figure 1 is a plan view of my buckle applied to a strap. Figure 2 is a section on the line 2 2 of Figure l. Figure 3 is a plan view of the buckle. Figure 4' is a bottom plan view of Figure 3. Figure 5 is a side elevation of the buckle, and Figure G is a side view of one member of the buckle.

The members 1 and 2 are, preferably, cast, the member 1 consisting of side bars 3 and 4. connected by transverse bars 5, 6 and 7, the latter bar having a denticulated outer edge a. The tongue member 2 is formed of side bars 8 and 9 connected by transverse bars 10 and 11. IThe bar 11 of the tongue member 2, when the buckle is assembled, is located forwardly of the denticulated bar 7 a sufficient distance to provide space for reception of the running part 19 of the strap, and has an upward inclination so as to clamp the strap against the teeth of the bar 7. The side bars 3 and 4 of the member 1 are extended upwardly, intermediate their length, to form bearings 12 and 13 in which are pivotally secured trunnions 14 and 15 integral with the bar 10.

In the manufacture of thermember 1 the bearings 12 and 13 are cast open, as shown in Figure 6, to receive the trunnions 14 and 15, and when the latter are in place, I close the bearings by bending the extensions 16 and 17 toward each other over the trunnions andso secure the members 1 and 2 together to form a completed buckle.

In using my buckle the end of a strap is passed around the bar 6 and under the bar 5 back upon itself where it is riveted or otherwise secured. The running part 19 of the strap is passed upwardly between the bar 11 and the denticulated bar 7 and over the bar 10 and then under the bar 5 between theA latter and the fixed part 18fof the strap. It will be noticed that the bar 5, of the part 1, and the bar 10 of the tongue member 2 are substantially inthe same horizontal plane as more clearly shown in Figure 5, and the bar 6 is in a lower plane but above the bottom line of the part 1 as shown more clearly in Figure 2, so thatvit follows that when-a strain is brought upon the strap, the part 2 will clamp the running part of the strap against the teeth of the bar 7, and as the strain will seek a straight line, the continued pull, acting upon the bar 11, with an upward stress, will exert its `force to rock y the part 1 so that the bar 5 will clamp the running part of the strap between the bar Y 5 and the part 18, the fixed part of the strap, so that the ruiming part 19 is thereby clamped against slipping and is held with a force which is added to by any increase in the strain of the pull.

I haveproduced a buckle which in continued experiments has proven of great value, particularly when it is used in a position where a positive securing of the strap against slipping is absolutely necessary and which can be relied upon for its efficiency under any conditions. What I claim is` 1. A buckle, composed of a main member ing bearings projecting upwardly from the sides thereof, the tongue member pivotally permit the passage of a strap upwardly between the forward ends of said members, a transverse bar on said main member rearwardly of said bearings below the plane thereof and above the plane of the lower side of the main member and to which one end of a strap is to be secured, a transverse bar on the rear of the main member in substantially the plane of said bearingsr and under which the running part of a strap is to be passed, said tongue member and main member co-operating to clamp the running part of the strap at both ends of the buckle.

2. A buckle, composed of a main member and a tongue member, the main member having bearings projecting upwardly from the sides thereof, a transverse denticulated bar atthe forward end of said member, a tongue member pivotally mounted in said bearings and a tongue member, the main member havand extending below and forwardh of the main member, a transverse bur on the tongue member forwardly of the @lenti-eu-v laterl bar and cof-operating therewith to clamp a strap passed between. Heem, a trams verse bar on said main member rearwardly of said bearings and below the plane there" of and above the plane of the lower side of the main member and 0 which lam e'nd Of aI l0 strap is to be secured,` and a transverse bar on the rear of the mai-n member in substantially the plane' of said bearings :m under which the running part of a strap isl to be passed and damped. simultaneously against the part of the strapA seeured to't'beV bar rear Wardof the bearings with and by the clampng action of the tongue member and the denticulated bar.
