STOVE PIPE Filed Jan. 26, 1940 14/) 22 j 4 1 j] 4 I 15/2 4 15 /7 16 2 flTT'UFi/VEW v Patented Oct. 14, 1941 UNITED STATES PATENT QFFICE STOVEPIPE Stan Skoko, Clackamas County, Oreg.
Application January 26, 1940, Serial No. 315,804
2 Claims.
My invention relates to improvements in stove 1311388.
The object of the invention is to provide a sheet metal stove pipe so constructed that it may be increased or decreased in diameter to accommodate other sections of stove pipes of difierent diameters, and at the same time allow two or more sections to telescope each other, a greater or less distance, and tightly held in said telescoped position.
Another object of the invention is to provide a stove pipe of this character, which can be readily assembled and adjusted to its proper diameter; and, at the same time, forms a stove pipe-the exterior of which has no sharp edges and has the appearance of the ordinary rolled seam of a rigid stove pipe.
A further object of the invention is to provide a simple and eiiective stove pipe which can be cheaply manufactured by modern machinery.
In the accompanying drawing:
Figure 1 is a perspective view of my improved stove pipe, showing the edges locked together;
Figure 2 is an enlarged end view of the joint between the edges and showing the wedge in sections;
Figure 3 is an enlarged end view of the two edges of a stove pipe separated, with the wedge removed;
Figure 4 is a plan view of one of the wedges.
Referring now to the drawing, Ill represents my improved stove pipe, which can be made of any desired length and diameter and split longitudinally thereof. The edge II is sharply bent at l9, having the portion l3 tightly pressed against the inner periphery of the pipe and is then bent inwardly at M to form the portion It approximately parallel with the portion l3.
The portion I l extends outwardly beyond the bend I9 a considerable distance and turns outwardly and inwardly, as indicated at l5, forming a hook. The other longitudinal edge l2 of the stove pipe is bent inwardly upon the inner periphery of the stove pipe, as indicated at [6,
By the structure herein described, it will be seen that the portion l1, and hook I8, is passed transversely into the space between the portions [3 and W of the opposing edge of the pipe with the portion l6 tightly engaging and forming a tight seal with the outer periphery of the stove pipe. The wedges 2| are then forced into the spaces between the portions l1 and the outer faces of the portions M between the hooked ends l5 and I8, whereby the edges of the stove pipe are drawn together, as clearly shown in Figure 2 of the drawing. This figure shows the maximum contraction of the stove pipe and, if a stove pipe of a greater diameter is required, the wedges are not entirely driven in, thus allowing the bent portion 20 to be spaced from the portion l9. desired to telescope two sections, a greater or less distance, it is only necessary to partially withdraw one of the wedges 2|, at one end of the pipe, to allow for the increase in diameter.
What I claim and desire to protect by Letters Patent of the United States is:
1. A stove pipe, comprising a cylindrical section split longitudinally thereof, one edge of the split provided with an outwardly and inwardly turned portion having a downwardly hooked portion beyond the split, the opposite edge of the split provided with an outwardly and inwardly turned portion having an upwardly hooked end beyond the split and adapted to intermesh with the first mentioned portion, and a wedge between the hooked ends and adapted to separate the same for drawing the edges of the split together.
2. A stove pipe, comprising a cylindrical section split longitudinally thereof, one edge of the split portion turned back upon the section for a considerable distance to form a loop, thence turned back over the loop and spaced therefrom and extending beyond the edge of the loop with its edge turned inwardly forming a hook, the other edge turned back upon the section for a considerable distance to form a loop and thence turned back over the loop and spaced therefrom and extending beyond the loop with its edge turned outwardly to form a hook, said edges being intermeshed, and a wedging plate between the hooked edges for separating the same and drawing the edges of the split together.
STAN SKOKO.
