UNITED STATES PATENT OFFICE.

GEORGE E. PRENTIGE, OF BERLIN, AND ROBERT C. LEGAT, OF NEW BRITAIN, CONNECTICUT. i

BUCKLE.

8 Application filed February To all whom it may concern:

Be it known that we, GEORGE E. PREN- TICE and ROBERT C. LEcA'r, citizens of the United States, residing, said PRENTIC-E at Berlin and said LEGAT at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Buckles, of which the following is a specification.

Our invention relates to improvements in buckles, of the form used for belt-s for mens wear, and the object of our improvement is to produce a buckle wherein the means pro-- vided for contacting with the belt and that is actuated by the clamping lever has a relatively large area opposed to and contacting therewith, whereby the buckle is particularly adapted to be used with belts of rubber, as with such belts a localized contact, confined to a small surface, in many cases results in making permanent changes in the material and in marking the surface thereof.

In the accompanying drawings Figure l is a front elevation of our improved buckle, showing parts of the belt with which it is used.

Figure 2 is a rear elevation of the same.

Figure 3 is a plan view of the same. Figure 4 is a rear elevation of the buckle only.

Figure 5 is a rear elevation of'the body in the position just previous to assembling the lever in place.

Figure 6 is a transverse sectional view on the line 6-6 of Fig. 2, being through the pintle bearings, the: clamping lever being shown in side elevation.

Figure 7 is a plan view of the blank for the body or frame.

ur improved buckle comprises a body or frame 10 of uniqueform that comprises in one piece of sheet metal different parts that serve to efi'ect correspondingly different functions, as will be described, and a swinging lever 11 that cooperates therewith for the purpose of clamping the movable or adjustable end portion 13 of the belt 14.

The fixed end 15 of the belt 14 is secured by clamping devices 16 to one end of the lever 11. The other end 17 of said lever 11 is in the form of a nose that operates to efiect the clamping of the belt end 13 in a manner to be described, and intermediate 1 1922. Serial No. 523,144.

said ends are the laterally directed supporting pintles l8. 1

The body 10 has a plate-like front wall 19 that is bordered at the top and bottom edges by the side walls 20 that project rearwardly and said side Walls 20 have each a rearward extension 21 in the form of an ear that has a of the pintles 18.

The bearing nose 17- swings within the space between the bearing holes 22 and the front wall 19 and in which space the belt end 13 to be clamped is housed.

Said bearing nose or contacting nose 17 does not bear directly upon the belt end 13, as intermediate these parts is a contacting structure of plate-like form that in the present instance is composed of two similar members 23 of plate-like form, positioned side by side longitudinally along the clamping space, and having the opposed edges 24 separated by a space 25.

As shown, said members or contacting plates 23 are integral with the body 10, being connected along a portion 26 of the rear free edge of the side wall 20, as shown, one on each side.

The blank for the frame 10 shows longitudinal slits 27 extending from one end inwardly that meet in each case a curved slit 28 that determines the outline of the car 21. Said

slits

27 and 28 serve to separate the free end portion 29 of the contacting plate 23 from the adjacent portion of the body 10. The opposite end portion 30 f said contacting plate 23 is connected to said bearing hole 22 for one body along the edge portion 26, as described. a

The curved edge 28 that is provided by the slit 28 that forms the car 21 provides a recess 31, along the outer border edge of the free end portion 29 of the contacting plate 23 that is useful in clamping a rubber belt in particular and helps with any belt in effecting a clamping, as under pressure the material of the belt will be to a certain extent forced therein and will cooperate with the opposed edges to resist tensile strain on the belt.

We claim as our invention l. A buckle comp-rising a body having a plate-like front wall and side Walls bordering opposite edges of said front wall, a clamping lever pivotally supported from said side walls, said lever being operative to press a belt end against said front Wall, and a pair of plate-like members'contacting on one face with said lever and adapted to make contact by the opposite face with said belt end, said members bein individually connected with said side Wal is '2. A buckle as described in claim 1, said members and side Walls being individually connected by means of longitudinally directed corner-junction structure, and said corner-junction structures being spaced longitudinally from the clamping lever, Where by the portions of said contacting members adjacent said lever Will be relatively free to flex and respond to the clamping movemen-ts of said lever.

3. A buckle as described in claim 1, the border edges of said members being recessed so as to admit material of the belt under pressure.

4. In a buckle, a body of channel form, having a plate-like front Wall that is bordered along opposite edges by side walls, a clamping lever pivotally supported from said side Walls, a plate-like belt contacting member interposed between said lever and front Wall, and said member being connected to said side Wall along a part of the longitudinally directed rear edge of said side wall.
