M LEWIS BROWN, F DETROIT, MICHIGAN, ASSIGNOR TO UNIVERSAL METAL COMPANY, OF DETROIT, MICHIGAN, A CGRPORATION OF MICHIGAN.
CHANNEL-TUBING.
Specification of Letters Patent.
Patented A11 24:, 1920.
Application filed May 25, 1914. Serial No. 840,656.
To all whom it may concern:
Be it known that I, M LEWIS BROWN, a
citizen of the United States of America, re
siding at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Channel-Tubing, of which the following is a specification, reference being had therein to the accompanying drawings.
The invention relates to channel tubing such as employed in the construction of wind-shield frames and for similar purposes, and the invention consists in the construction as hereinafter set forth.
In the drawings:
Figure 1 is an enlarged sectional perspective view of the tubing; and
Figs. 2, 3 and 4 are cross sections showing slightly modified constructions.
It is one of the objects of the invention to obtain a construction in which the tubing may be formed out from a single strip of sheet metal bent to form both the outer tube and the channel portion and with a lock-seam uniting the meeting edges. It is a further object to so arrange this lookseam that it forms a brace between the channel and the outer tube while the latter forms an abutment facilitating the closing of the seam. As shown in F ig. 1, A is the outer tube which is bent inwardly at B and B to form the parallel walls of the channel C. The portion B is bent at right angles to form the bottom member D of the channel, which extends to the opposite wall of the outer tube and is then return-bent at E to receive an angle flange F on the portion B. The return-bend E extends inward to form an abutment for the member B which limits the outward movement thereof, while the rounded edge or bend proper G bears against the inner face of the outer wall so as to limit outward movement. Thus when the tube is completed and in use, there will be no tendency for the seam to open.
In Figs. 2, 3 and 4 modified constructions are shown, in which the cross sectional con, tour of the outer tube is varied. In each case, however, there is the same arrangement of the seam extending between the wall of the channel and the adjacent wall of the outer tube.
Channel tubing constructed as described is better adapted for receiving a filler block than constructions in which the seam between the edges of the blank extends downward beyond the bottom of the channel. Thus it is only necessary to cut away the cylindrical filler block so as to form a flat side to abut against the bottom of the channel portion, whereas with the seam projecting downward it is necessary to curve the block to provide clearance therefor.
\Vhat I claim as my invention is 1. A channel tubing comprising a fashioned sheet metal blank having an integral channel portion comprising two sides and a bottom and an outer surrounding portion, the opposite edges of said blank meeting at one corner of the channel portion and being bent to form a lock seam with the thickness of the seam located in the space between one side of the channel portion and the outer tubing and engaging said outer tubing.
2. A channel tubing, comprising a channel portion and a surrounding outer tube formed from a single sheet metal strip, the bottom section of the channel being extended to the outer tube portion and return-bent, and a side wall of the channel being bent outward to engage said returnbent portion and form in conjunction therewith a seam.
3. A channel tubing, comprising a channel portion and a surrounding outer tube formed of a single sheet metal blank, said channel portion having rectangular sides and bottom, the latter being extended be yond one of the sides to the wall of the outer tube and return-bent to extend in reverse direction. to said side and said side being provided with an outwardly-extending flange embraced by said return-bent portion.
4. A channel tubing comprising a chan nel portion and a surrounding outer tube portion formed from a single strip, the bottom of said channel portion extending beyond the side of the channel and into contact with the outer tube and being return-bent, and the side of said channel being provided with an outwardly-extending angle flange embraced by said return-bent flange, having its outer edge extending to the bend and abutting thereagainst.
5. A channel tubing comprising a fashioned sheet metal blank having a channel portion and an outer surrounding portion, the channel portion comprising two parallel sides and a bottom at right angles thereto,
the opposite edges of said blank meeting at one corner'ofthe channel portion to form an interlocking seam extending from the channel to the outer tubing, one side of the seam being flush With the inner side of the bottom ofthe channel portion.
In testimony whereof, I affix my signature in presence of two Witnesses. V
M LEWIS BROWN.
