To all whdin it fittty concern.-

Be it known that I, ANTON OHNEMUS, a citi- Zen of the United States, residing at Quincy, in the county of Adams and State of Illinois, have invented certain new and useful Improvements in Nestable Stovepipes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming partof this description.

My invention relates to that class of stovepipes so constructed that they maybe shipped in collapsed condition nested together, so as to economize space, the objectof the invention being to so construct pipe-sections of this description that they may be readily joined at the meeting edges by even. an unskilled workman and the seams being so formed that when produced they will be firmly held against lateral or longitudinal displacement.

I am aware that it is not new to construct collapsible and nestable Stovepipe-sections; but as heretofore made such sections have usually been provided with the usual overlapping longitudinal tongues that form the seams and the seams being secured by a rivet inserted in the upper end of such section to prevent the seams from springing open when another section of pipe is forced over the end thereof. Another method of forming the seams has been to cut tongues from the pipe-sections that overlapped the tongues of the seam, so as to avoid its springing open. In the use of a rivet it is necessary that the person producing the seam to join the edges of the pipe-section be a workman who is capable of applying the rivet and has the necessary facilities for so doing. The use of the tongues referred to is objectionable in that they are liable to become broken or fractured in the process of manufacture of the pipe-sections or broken off in handling or transportation of the pipe-sec tions. It has been my aim to produceapipesection of such construction that the objectionable features of such sections as heretofore made are entirely overcome and, furthermore, to produce an article in which the seam may be readily made by any person, whether a skilled workman or not, the form of the article being such that it is only necessary to use a hammer or mallet in making the seam and I securing it firmly to avoid liability of displace;

ment thereof. I H

Figure I is a perspective View of one end of a pipe-section constructed in accordance with my invention. Fig. II is an end view, shown enlarged, of the meeting or tongue edges of the pipe section. Fig. III is an elevation of the end of the section in open condition. Fig;

IV is an elevation showing the seam thereof secured. Fig. V is a View showing a number of pipe-sections in collapsed condition nested together for shipment.

l'designates a pipe-section provided with longitudinal tongues 2 and 3, designed to be interlocked with each other and to be flattened to form a seam by the use of a hammer or mallet in the usual manner in which such seams are commonly made.

One of the edges of the pipe-section is cut away diagonally at 4 at the end of the section, the cut being produced through the outer tongue 2 as well as through the adjacent portion of the body of the section. When the seam is to be produced, the edges of the section are brought together so that the tongue 2 enters beneath thetongue 3, and the tongues are then flattened in the usual manner by the use of a hammer or mallet. The corner 3 at the end of the tongue 3 at this time projects beyond the diagonal cut-away portion 4 of the opposite edge of the section to the extent, indicated by the dotted line A, Fig. III. The corner 3 of the'tongue 3 is then bent backward on the line A, Fig. III, over the diagonal cut-away portion of the opposite edge of the section, as seen in Fig. IV, and firmly hammered down, so as to secure the same in an effectual manner against springing open or against endwise displacement. It will be seen by which the tongues are flattened and the 5 corner 3 is bent over and lapped onto the same. Moreover, there is no part of the pipesection that is liable to become broken or injured in any way in the process of manufacture or in handling during transportation.

While I have referred to the herein deedges cut away at the end thereof to receive scribed pipe as a Stovepipe, I do notwish the coincident corner of the o'pposing tongue 10 to be restricted to a pipe of this nature, as the when lapped thereover, substantially as deconstruction might be of utility in other described.
