Patented May 4, 1915.
Application filed March 1, 1912. Serial No. 680,992.
To all whom it may concern:
Be it known that we, ROBERT ORR and BURLEIGH S. ANNIS, citizens of the United States of America, and residents of Chattaand useful Improvements in Stovepipe-Sections, of which the following is a specifica- -tion.
This invention relates to stove pipes and 1 particularly to means for fastening the edges of stove pipes by detachably coupling, which will permit the edges of the stove pipe section to be secured together without the use of mechanical appliances.
An object of this invention is to provide a stove pipe section with interlocking joints in order that the edges of the sections may be secured together after shipment, thereby enabling the manufacturer to ship the same knocked-down thereby economizing in space and in the cost of preparation for shipment.
With the foregoing and other objects in view, the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.
In describing the invention in detail, reference will be had to the accompanying 80 drawings forming part of this specification wherein like characters denote correspond,- ing parts in the several views, and in which-,-
Figure 1 illustrates a plan view of a frag- 85 ment of a stove pipe section in blank form; Fig. 2 illustrates a view in elevation of a fragment of the stove pipe section with the edges of the said section connected; Fig. 3 illustrates a transverse sectional view through the coupling shown in Fig. 2; Fig.
, 4 illustrates an end View of a fragment of the stove pipe section showing the joints just prior to their being interlocked; and Fig. 5 illustrates a perspective view of a fragment 5 of a stove pipe section showing the parts in position, partially interlocked and prior to the completion of the manipulation result ing in the finished joint.
In these drawings 6 denotes a blank from which the pipe is formed, one edge thereof being bent to form a channel for the reception of a flange and securing device to be presently explained which is formed on the opposite edge of the blank. The channel 18 referably formed by bending the blank rom which the stove pipe section 1s nooga, Tennessee, have invented certain new.
formed, near the edge, over upon theiblank and in then bending the said edge portion on itself to produce an intervening space or way 7, the flange 8 produced by the operation on the said bent portion having its marginal edge bent to form a way 9 for the reception of the securing device to be presently explained. As is shown in Fig. 3, a portion of the section that is bent to form the way 9 projectsbeyond the shoulder 10 which is produced in the formation of the blank just described and the parts are so proportioned as to afford an opening between the shoulder 10 and the edge of the flange 8 for the reception of a flange 11, which is formed on the opposite edge of the blanks A shoulder 12 is formed at the intersection of the flange '11 and the blank 6 and a tongue 13 is formed at the point of intersection of the flange and the blank, the said tongue being integral with the flange at the shoulder 12. The edge of the tongue remote from the flange is beveled to produce a cam which is designed to act on the wall of-the flange forming the way 9 which is provided for the reception of the tongue. Asshown in Fig. 1 of the drawing the tongue has free edges at its ends and side and it is preferably oflset with respect to-the side of the blank from which it is formed, and is in the same surface as the flange l1.
In order that the tongue hereinafter referred to adjacent the lower end of the section may be interlocked; "with the way 9, formed by the bend of the longitudinal edge of the section, we have cut away a portion of the marginal edge as at 9', adjacent the portion of the way 9 in order that the tongue opposite the cut away portion may occupy the pocket prior to the final positioning of the tongues in the way 9.
In assembling the edges of the blank and holding them in interlocked engagement, the flange 11 is inserted in the way 7 its entire, width and preferably its entire length. That portion of the blank carrying the tongue is then drawn longitudinally so that the blank is twisted slightly, the movement given the sectionsbeing sufficient to cause the inner end of the tongue to pass beyond the ends of the spaces 7 and 9. When the parts are in the relation just indicated, the part containing the tongue is pushed back until the ends are even and during the return movement the tongue 13 will enter the way 9 and the two members will be securely locked together, it being understood that the cam of the tongue will ride against the inner wall of the flange and exert pressure laterally of the flange 11 so that the shoulder 12 will be pressed in close contact with the shoulder 10 to produce a finished appearance and a close joint.
Fig. 1 shows that more than one tongue is employed since there is shown in Fig. 1
la tongue near the upper end and also a tongue near the lower portion of the fragment which latter tongue would be intermediate the length of the pipe section. In the forming of an opening for the reception of the so-called intermediate tongue, a portion of the flange bent to form the pocket 9 is removed to form a clearance for the said intermediate tongue in order that it may enter the said clearance and pass back of the flange 8 simultaneously with the entrance of the upper tongue in the channel or pocket as explained hereinbefore.
It will be observed from the foregoing de scription that stove pipe sections made in accordance with this invention may be shipped in their flat state or they may be slightly bent in order that the sections may be nested for the purpose of economizing in space and when the stove pipe sections are to be assembled, it is only necessary to bend such sections on a former to produce the pipes and the edges may be caused to interlockin the manner'stated.
While we have stated that the blanks may be shipped in their fiat state, it is also obvious that they may be bent to their required shape and shipped in that condition with their edges unsecured but the exact conditions of shipment is an immaterial matter and is simply suggested here for the purpose of demonstrating the utility of the mes es device made in ,accordance with this invention.
We claim:
1. Astove pipe section comprising a sheet of metal one edge of the sheet of metal being folded upon itself to form pockets, an offset flange comprising the oppositeedge of the sheet, and a tongue stamped from the sheet of metal, adjacent the ofi'set portion of the flange, said tongue projecting rearwardly and adapted to engage within one of the pockets, and said flange adapted to engage within the opposite pocket when the edges of the sheet of metal are brought together.
2. A stove pipe section comprising a sheet of metal having a portion of one edge overlying a part of the main body of the sheet and forming a double pocket, an ofl'set flange on the opposite edge of the sheet, a shoulder constituting an abutment for the extreme edge of the overlying portion of the section when the edges are brought together, tongues stamped from the sheet adjacent the offset flange, said tongues having an inclined edge cooperating with the respective pockets for providing a wedging action between the tongues and pockets, said tongues being constructed to assume a position in spaced relation with the pipe section when the edges thereof are brought into engagement with each other. i
In testimony whereof, we hereunto aflix our signatures in the presence of two witnesses. I
