TRESTLE CLAMP Filed Jan. 28, 1949 Patented June 5, 19541 Y UNITED STATES PATENT OFFICE TRESTLE CLAMP Paul L. Morton, Long Beach, Calif.

Application January 28, 1949, Serial No. 73,247

1 Claim.

This invention relates to an all purpose clamp for the purpose of mounting and holding the legs of a sawhorse or other supports, such as, a rack, a hoist frame, and the like.

An object of my invention is to provide a simple, inexpensive and eiective clamp, which is simple to manufacture and which will effectively hold the legs of a sawhorse, and the like, in an effective manner.

A feature of my invention is to provide a novel all purpose clamp, which can be easily fabricated to hold wooden timbers, such as legs of a sawhorse.

Other objects, advantages and features of invention may appear from the accompanying drawing, the subjoined detailed description and the appended claim.

In the drawing:

Figure 1 is a side elevation of my clamp.

Figure 2 is an end view of the same.

Figure 3 is a perspective view of one side of the clamp.

Figure 4 is a sectional view taken on line 4-4 of Figure 2.

Referring more particularly to the drawing, my clamp consists of two complementary members, I and 2. These members are each formed of a suitable weight of metal and since they are substantially identical, only one will be described in detail.

Each half of the clamp consists of a U-shaped strip of metal, which is stamped from a plate sheet and then bent into a substantial U shape, as shown in Figure 3. A pair of ears 3 and 4 are integrally formed in the sheet of metal and these ears provide a means to attach the sections I and 2 together. A bolt or rivet 5 and 6 extends through the ears 3 and 4 respectively, thus securing the parts of the clamp together.

A lip 'I is bent horizontally across the top of the clamp sections I and 2, substantially as shown, and this lip acts as a stop for the leg timber 8 and to prevent the leg from moving upwardly through the clamp. A wall 9 is Welded or otherwise xedly secured in the U shape structure of the clamp section I and acts as a side wall to support and conne the timber 8. The inwardly bent portions of the clamp section I are formed with teeth I0 to engage and grip the horizontal timber I I, which is found in the usual sawhorse. A bracket I2 extends between the legs of the sawhorse, or the like, to spread these legs the proper amount and to thus cause the teeth I0 to sink into the horizontal timber Il.

The ears 3 and 4 are each cut with a flat upper horizontal surface I3 and I4, which serve as a recess to conform to the shape of the horizontal timber I I.

Having described my invention, I claim:

A clamp for sawhorses and the like, comprising a pair of complementary clamp members, each member consisting of integrally formed side and outer walls, a second wall spaced from the outer wall and substantially parallel thereto and ilXedly mounted between the side Walls whereby a socket is formed to receive the end of a supporting member, an ear formed on each of the said Walls of each clamp member, a rivet pin extending through the ears to hingedly secure the clamp member together, a stop lip formed at the top of said outer wall, said lip being bent at right angles and extending towards said second wall to act as a stop for the supporting member, and teeth formed on the inner edge of each of the sides oi" the clamp.
