STOVEPIPE AND SIMILAR PIPE.
Application filed March 25, 1927. Serial No. 178,461.
definite manner in order to effect this open- Further objects are to provide a novel form of stove pipe which may be very cheap- 15 ly and simply produced and which is eX- tremely easy to operate.
An embodiment of the invention is shown in the accompanying drawings in which:
Figure 1 is a view of the pipe with its edges open or detached and with parts broken away;
Figure 2 is a sectional view through the pipe showing the edges interlocked and with a portion of the pipe broken away;
Figure 3 is a fragmentary end view of the pipe, such view being drawn to an enlarged scale.
'Referring to the drawings, it will be seen that the pipe is formed from a sheet metal cylinder 1, one edge of which is provided with a reversely folded portion 2 which is continued outwardly into an outwardly folded portion 3 spaced from the portion 2 to provide a longitudinally extending channel. The other edge of the pipe is indicated by the reference character 4- and a pair of tongues 5 project therefrom. These tongues are adapted to enter slots 6 formed in the 1 base of the folded portion of the channel portion of the other edge of the pipe, as illustrated in Figures 52 and 3. Each of the tongues is formed with a shoulder 7 at its lower edge and with a curved upper portion 8 at its upper edge. Also, the'lower outer side of the tongues is cut away as indicated at 9. The construction is such that a parallel sided slot is formed, between the tongue and the edge 4 of the pipe.
In assembling the pipe, the curved ends of the tongues are inserted in the slots 6 and a relative shifting motion is imparted to the two edge portions of the pipe. so that the tongues will enter and slide into the slots, thus carrying the shoulder 7 inwardly. After this has been done, the two edge portions of the pipe are reversely moved to cause abutting relation between the shoulder 7 and the bottom edge of the slot, as shown in Figure 2. This prevents further relative shifting motion of the edge portions of the pipe, and it will be noted that the upper part of the pipe adjacent the slot, indicated by the reference character 11 in Figure 2, is received between the parallel faces formed between the tongues 5 and the edge 4.
Thus, a very positive interlock is secured and inadvertent separation of the parts is prevented.
It will be noted further that the device may be very cheaply formed and that no additional fasteners are required, thus materially reducing the expense in the manufacture of these pipes.
' It is intended that the term stove pipe be interpreted to include any similar type of pipe formed in the manner set forth.
Although the invention has been described in considerable detail, such description is intended as illustrative rather than limiting as the invention may be variously embodied and as the scope of such invention is to be determined as claimed.
We claim:
A stove pipe comprising a sheet metal cylindrical body portion provided with jux taposed edges, one edge portion being folded to provide a channel for the reception of the other edge portion and being provided with slots, the other edge portion having so projecting tongues formed integral there-- with and each tongue being provided with an abrupt shoulder which joins a curved portion adjacent one end and with a rounded portion adjacent the other end, said rounded portion merging into a parallel sided slot formed between the tongue and the last mentioned edge of the body portion, the Width of the tongues being approximately constant at all points measured longitudinally and the Width of the slots being approximately equal to the width of the tongues, whereby each tongue may enter its corresponding slot and the abrupt shoulder rest against one end portion of the slot While the said par allel sided slot receives a portien 0f the first mentioned edge. 19 In testimony that We claim the foregoing We have hereunto set our hands at Mil- Waukee in the county of Milwaukee and State of Visconsin.
