UNITED STATES PATENT ()FFICEQ SAMUEL l1 NTES, OF READING, PENNSYLVANIA.

51 C LA M P.

5P' ECIFICA.TION forming part of Letters Patent No. 339,072, dated March 30, 1886.

Application filed l ehruary 20, 1880. Serial No. 192,718. (No model.)

To all whom it 12mg concern:

Be it known that I, SAMUEL E. Nins, a citizen of the United States, and a resident of Reading, in the county of Berks and State of 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 inthe art 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 improved 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 corre sponding parts in all the figures.

My invention has relation to clamps for the use of carpenters, cabinet-makers, and similar mechanics, for the purpose of holding portions of carpenter or cabinet work together after it has been glued together; and 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 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, 0, which 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 fiat handle, G, at 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 frameis formed with a flat face, J, against which the flat face of the swiveled head faces, and the object to be glued may be clamped between the flat faces of the cndof 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, L, and a screw, M, having a swiveled head,

N, at its inner end, provided with a flat face, 0, and a handle, I, at its outer end, slides in this slot, and has a nut, Q, upon its inner portion, which nut may rest in the recess 1n the frame. \Vhen the corner of a frame is to 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 screw is forced with its flat head against the edge of the other side piece of the frame, forcing 1t against the other piece and holding it n position until the glue has hardened, and 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 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 are bearing are plane as it they are beveled or form a portion of a molding, the heads being swiveledbyball-andsoeketjoinls. Theclamp may also be used where two pieces are glued together with their faces toward each other, and a third piece is glued to the ends of these two 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 lo the same, or nearly so.

The clamp may be made in several SlZCS, 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 artr cles of considerable thickness.

Having thus described my invention, l. clai m and desire to secure by Letters Patent of the United States- In a clamp for holding articles to be joined together, the combination of a round frame having one end formed with a head provided with a screw-threaded perforation, and havinga head at the other end formed with a flat head and formed with a longitudinal slot at a point diametrically opposite to the aperture in the frame formed with a recess upon the inner side of the frame, a screw fitting inthe threaded perforation and having a handle at In testimony that I claim the foregoingas my TC its outer end' and a head swiveled by a ballown [have hereunto affixed my signature in and-socket joint to its inner end, a screw passpresence of two witnesses.

ing through the slot and having a head at its in- 5 ner endswiveledto it byaball-and-soeketjoint SAMUEL E. NIES.

and having a handle at its outer end; and a bearing in the recess in the frame, as and for CHARLES E. SGIIRADER,

a a a nut httlng upon the inner portion of the screw l \Vituessesz the purpose shown and set forth. I WTLL R. HENNINGER.
