CLAMP.

SPECIFICATION forming part of Letters Patent No. 555,614, dated March 3, 1896.

Application filed April 2'7, 1895. $erial No. 547,398. (No model.)

To all whom it may concern.-

Be it known that I, JAMES MOWRER, a citizen of the United States, residing at Casper, in the county of Natrona and State of Wyoming, have invented certain new and useful Improvements in Clamps; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvement-s in that class of clamps which comprise two loops and are provided with screws for clamping articles in said loops, and its novelty will be fully understood from the following description and claim when taken in conjunction with the annexed drawings, in which Figure 1 is a View illustrating the manner of using my improved clamp; and Fig. 2 is an enlarged transverse section taken in the plane indicated by the line 00 00 of Fig. 1, looking in the direction of the arrow.

Referring by letter to said drawings, A A indicate the sections of a window-frame.

B indicates a square, and 0 indicates my improved clamps, of which two are preferably employed in conjunction. The body D of these clamps O- is cast in one piece and has all of its parts resting in the same plane, as shown, so that a plurality of the clamps will take up but a minimum amount of room when not in "use. The said body D comprises the large loop or elbow a, which is designed to straddle a frame-section, and the smaller loop b, which-rests approximately at right angles to the loop a and in the same plane therewith, and is designed to straddle the square so as to hold the same against the frame-section, as illustrated. At or adjacent to its ends the body D is provided with threaded apertures or bores c d, which are disposed at right angles to each other and are designed to receive the binding-screws E F, which in turn are designed and adapted to engage the frame-sec tion and square, respectively, as better illustrated in Fig. 2.

In order to prevent the binding-screw F from scratching, indenting, or otherwise marring the square, I provide the bearing-plate G, which is connected to the inner side of the loop Z), as shown, and is designed to rest between the screw F and the square and receive the impingement of said screw.

The manner of using my improved clamps is illustrated in Fig. 1, and is as follows: The clamps O are first connected to the blade and tongue of the square B, as illustrated, and the clamps are then adjusted so that the loops a will straddle the frame-sections and the blade and tongue of the square will rest against the inner sides of the sections and at right angles thereto. The screws E are then tightened, so as to draw the square tightly against the frame-sections, when said sections will be held in a perfectly-square position for the purpose before stated.

When it is desired to remove the clamps from the frame-sections and the square, it is simply necessary to loosen the screws E, so that the clamps and the square may be disconnected from the frame-sections and the screws F, so that the clamps may be disconnected from the square. As better illustrated in Fig. 2, the loops a b are arranged at right angles to each other and in the same plane, and so that the mouth of the loop a rests at the side of the mouth of loop I) and opposite the threaded bore 0, which receives the screw E. This permits of the square resting at right angles to the frame-sections and also enables a single screw E, by binding a frame-section against the edge of the square, to securely hold the frame-section in position and in proper relation to the square.

The threaded bores c and cl are arranged in the same plane as the body portion D of the clamp, as are also the screws E F, and in consequence of this and the fact that all the parts of the said body are in the same plane, as before stated, it will be seen that a number of the clamps when not in use may be placed in a very small space and that they may be very easily handled.

It will be seen from the foregoing description, taken in connection with the drawings, that my improved clamps are exceedingly cheap and simple; that they may be readily applied, and that they will serve effectually to hold the sections of a Window-frame perfectly square, which is an important desideratuln.

Having described my invention, what I claim is The clamp described consisting essentially of the body portion D, formed in one piece with all its parts in the same plane and having the threaded apertures or bores a, (Z, adjacent to its ends; said apertures or bores being disposed in the same plane as the body and at right angles to each other, and also havin g the loops a, b, resting at right angles to each other and in the same plane and so that the mouth of the loop 1), will be at the side of the mouth of the loop a, and communicate therewith, and
