To all whom it may concern:

Be it known that I, Samuel E. Nies, a citizen of the United States, and a resident of Reading, in the county of Berks and State of 5 Pennsylvania, have invented certain new and useful Improvements in Miter-Clamps; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to to. which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which—

Figure 1 is a perspective view of my im15 proved miter-clamp, showing it applied to the corner of a frame. Fig. 2 is a similar view of the clamp separate, and Fig. 3 is a sectional view of the same.

Similar letters of reference indicate coitc20 spending parts in all the figures.

My invention has relation to clamps for the use of carpenters, cabinet-makers, and similar mechanics, for the purpose ofholding portions of carpenter or cabinet work together 25 after it has been glued together; aijd it consists in the improved construction and combination of parts of the same, as hereinafter more fully described and claimed.

In the accompanying drawings, the letter 3c A indicates the clamp frame, which frame is preferably circular, or nearly so, and cut out at one place to form a space, into, which the work may be introduced. One end, B, of the facing ends is formed with a head, C, which 35 is provided with a flat face, D, and a screwthreaded perforation, E, opening in the face and at the outer side of the curved portion of the end, and a screw, F, fits in this perforation, and is provided with a flat handle, G, at 40 its outer end, and with a swiveled head, H, at its inner end, the said head having a flat face. The other end, I, of the frame is formed with, a flat face, J, against which the flat face of the swiveled head faces, and the object to 45 be glued may be clamped between the flat faces of the end of the frame and of the head. Diametrically opposite to the opening in the frame is a slot, K, and the inner side of the frame is cut away at the slot to form a recess, 50 L, and a screw-, M, having a swiveled head,

N, at its inner end, provided with a flat face, O, and a handle, P, at its outer end, slides in this slot, and has a nut·, Q, upon its inner portion, which nut may rest in the recess in the frame. When the corner oi a frame is to 55 be glued together, the one side of the frame is clamped by the clamping-screw against the flat head of the frame, and the central screwis forced with its flat head against the edge of the other side jtiece of the frame, forcing it 6o against the other piece and holding it in position until the glue has hardened, aud it will be- seen that, on account of the central screw sliding in the slot, the said screw may be brought to bear directly against the edge of 65 the frame, regardless of the thickness of the frame, and the heads of the screws being swiveled, they may be brought to bear squarely against the portions to be glued together, as well when the surfaces upon which the heads 70 are bearing are plane as it they arc beveled, or form a portion of a molding, the heads being swiveled by ball-and-socket joints. Theclamp may also be used where two pieces are glued together with their faces toward each other, 75 and a third piece is glued to the ends of these tw-o pieces at a right angle, to the same, as well as where the end of one piece is glued to the side of another piece at a right angle to the same, or nearly so. , ⁸⁰

The clamp may be made in several sizes, and may have more or less space between its ends, as the work to which it is intended may require; but the screws will allow considerable variety in the size and shape of the work to be held clamped, as they are of a sufficient length to clamp small articles as well as articles of considerable thickness.
