STOVE PIPE.

UNITED STATES PATENT OFFICE.

CHARLES A. SHITH, OF MINERVA, OHIO.

STOVE-PIPE.

SPECIFICATION forming part of Letters Patent N 0. 369,211, dated August 30, 1887.

Application filed October 22,1886. Serial No. 216,965. (No model.)

To aZZ whom it may concern.-

Be it known that I, CHARLES A. SMITH, a citizen of the United States, residing at Minerva, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Stove-Pipes; 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, reference being had to the accompanying drawings, and to the letters-and figures of reference marked thereon, which form apart of this specification.

My invention relates to joints of pipes principally designed to convey the smoke away from stoves.

The object of the invention is to devise a construction of joint which will be simple andeconomical-in cost, readily packed into a small compass for storing or shipment, easily put together without heating or riveting the seams, as the end of one joint forming a band encompasses the end of the adjacent joint and prevents its spreading, while the seam is so formed that the joint will not give inward.

The invention consists in the novel features more fully hereinafter set forth and claimed, and shown in the annexed drawings,in which- Figure 1 is a side view of two joints of pipe of my construction. Fig. 2 is a top view. Fig. 3 is a sectional detail showing the seam partially opened, Fig. 4 a perspective view of a nest of joints.

The joint of pipe A may be made of any suitable material, sheet metal being preferable, and of any size and length. The proximate edges overlap to make a closed seam. The one, B, remains intact. The other, B, is bent back on itself, forming the fold .b, and thence forward, makingthe second fold, b, between which a space, I), is left for the recep tion of the edge B, whichnnay be slipped in or out, as desired. One end of the fold b, preferably the lower end, G, is cut away to permit the overlapping edges to lie adjacent to each other at this point, and be secured to gether by a rivet, D.

The seam is formed by slipping the edge B into the space I) in the fold b, and the rivet D 50 is passed through openings punched near the lower corners previous to the rolling of the sheets. It will be seen that the lower ends of each joint are the only parts secured, and when put together the upper end of each joint is slipped into the lower end of the one above it. By this means the lower end of one joint forms a brace for the upper end of the other and prevents spreading.

To pack the joints the upper ends are spread and one slipped into the other, as shown in Fig. 4. For domestic uses the advantages are at once apparent when storing the stove-pipes during the warm season, as a number ofjoints can be packed into a space not much larger than that usually occupied by one joint. The

joints can be easily packed, unpacked, put together,and taken apart by any person. The upper ends are spun in the usual manner to reduce them slightly, so they may slip into the lower ends of each other. A bead spun near the upper ends prevents the joints slipping within each other too far when set up.

In packing the pipe for shipping the joints can be slipped together, as stated above, with or without being first riveted.

Having thus described my invention, what I claim, and desire to secure by LettersPatent, 1s-

In a joint of stove-pipe, the combination, as hereinbefore set forth, consisting of the joint of pipe having its proximate edges overlapping, one edge having a fold which receives the opposite edge, and which fold is shortened by having a portion at one end cut away, and

the rivet located in line with and at the end of 85 theshortenedfold and uniting said overlapping edges at one end only, and forming a pivot for the edges to tilt about, whereby the opposite or freeends can be separated for nesting a number of suchjoints, which joints, when set up, will have the separable ends held together by fitting within the riveted ends, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES A. SMITH.
