TUBULAR STRUCTURAL MEMBER.

Specification of Letters Patent.

Patented Nov. 5, 1907'.

Application filed July 26, 1906. Serial No. 327,955.

To all whom it may concern:

Be it known that I, HARRY C. GAMMETER, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Chio, have invented a certain new and useful Improvement in Tubular Structural Members, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

The object of this invention is to provide a struetural member (rod, column, shaft, brace, beam, tie, etc.) for use where great strength must be combined with extreme lightness in weight.

To this end the invention consists of a tubular structural member formed of sheet metal and rolled upon itself to present internal bracing. Combined with suchrolled tube may be a suitable connecting member mounted within the tube. These features of invention are hereinafter more fully explained and are definitely summarized in the claims.

In the drawings, Figure l is a side elevation of my structural member, being partly broken away to show the connecting member. Fig. 2 is a cross section adjacent to such connecting member. Fig. 3 is a cross section at another point, and Fig. 4 is a cross section showing the structural member with the internal bracing amplified.

My structural member includes a tube rolled from sheet metal, preferably high-grade steel, the intermediate portion of the sheet, designated l, making substantially a complete circumference and the two portions 2 beyond this circumferential portion extending diametiically inward across the tube, the extreme portions 3 being turned outwardly in an arc to lie along the inner surface of the portion l. A suitable binder as a wire l0 passing around the tube and having its ends twisted together, securely holds the structure against separation. When my structural member is used horizontally after the manner of a beam, the stress being downward, the diametrical portions 2 give the member the required stiffness and strength.

`Where my member is used as a column, or when the stress is in various directions, the portions 3 which lie on the inside of the main shell l may be extended further within that shell, as shown in Fig. 4, and may be turned inward at 4 and then further turned at 5 to lie alongside of the diametrical portions 2. This method oi forming the member may be carried as far as desired, the essential being that the member is rolled on itself from sheet metal to form a tubular structure internally braced by portions of the sheet metal.

To furnish means for supporting my member, or making outside connections therewith, I provide the flat connecting plates 8 which are located at suitable intervals, preferably between adjacent binders l0, and extend inwardly between the members 2 and are then turned outwardly at 9 between the portions 3 and the shell l, as shown in Fig. 2. Outside of the tube,

I provide an eyelet 7 passing through the two plates 8 and securing them together. Connections may thus be made with the members at any desired point.

After my tubular member is constructed, the same may be given the proper temper by heating 'and immersing in oil, as is well understood.

l claim:

-l. In a tubular structural member, the combination of a sheet metal shell bent to present nearly a complete periphery and having integral portions extending inwardly adjacent to each other, said integral portions continuing diametrically across the shell and being turned outwardly along the inner surface of the shell.

2. In a tubular structural member, the combination of a sheet metal shell having integral portions extendingl inwardly and continuing across the shell and being turned outwardly in arcs along the inner surface of the shell, there being integral portions turned from the ends of the arc-shaped portions inwardly into engagement with the tirstanentioned portions.

3. A tubular structural member comprising a `shell with inturned portions and a connecting plate lying between such portions.

4. A tubular structural member comprising a shell with inturned diametric portions and a connecting plate lying between such portions,v said plate having its inner end turned to lie alongside of the shell and being held between it and the diametric portions.

5. The combination of a tubular member having a pair of parallel inturned integral portions, a connecting plate lying between such portions and extending outside of the tube, and a binder passing around the member.

G. '.L'he combination of a tubular member having a pair ot' parallel inturned integral portions, a connectingl plate lying between such portions and extending outside of the tube, and an eyelet passing through such connecting plate.

T. A tubular structural member comprising a shell with inturned diametric portions, combined with a pair of plates lying between such portions, said plates having their inner ends turned to lie alongside of the shell and being held between it and the diametric portions, and an eyelet outside of the shell connecting said pair of plates.

8. The combination of a sheet metal member formed to present a cylindrical exterior and having integral portions turned inwardly substantially diametrically, said integral portions being further turned outwardly parallel with the cylindrical portion, a connecting member consisting of a pair of plates between such diametrical portions, said plates having their ends turned outwardly in opposite directions between the cylindrical shell and the outward extensions of the dzunetric portions.

9. 'l'he combination of a sheet metal member formed to present n tubular shell with integral portions turned in wardly, such inturned portions being,l extended parallel with the shell, a connecting member Consistinf.;l of a pair of plates between such inturnecl portions, said plates having Atheir ends turned and lying,l between the shell and the extensions of the inturned portions, an eyelet passing through said pair of plates and Wires passing 10 around the shell adjacent to the connecting plates and binding the structure together.

ln testimony whereof, l hereunto affix Iny signature in the presence of two Witnesses.

HARRY C. GAMMETER.
