Description
NITED STATES PATENT OFFICE.
EDIVARI) I.. CLARK, OF PITTSBURG, PENNSYLVANIA.
HOLLOW BAR.
SPECIFICATION forming part of Letters Patent No. 456,646, dated July 28, 1891.
Application tiled January 26, 1891. Serial No. 379.101.V (No model.)
To all whom it may concern,.-
Be it known that I, EDWARD L. CLRK, of Pittsburg, in the county of Allegheny and State of. Pennsylvania, have invented a new and useful Improvement in Spiral Hollow Bars, of which the following is a full, clear, and exact description. My invention relates to an improvement in bars or rods of metal adapted to be used for fence-posts, am? for other tratcd in the accompanying drawings, in which- Figure l is a plan View of a rod embodying my invention. Fig. is a longitudinal axial section thereof, and Fig. 3 is a cross-section on the line III III of Fig. l.
The article shown in the drawings is a hollow rod made by twisting into spiral forma strip ot' metal (iron or steel) preferably with l suiieient tightness to cause the edges to meet .seas to forni the spiral ridge.
purposes where a strong light structure is required. It is illusand by continuing it they exert pressure on each other and are thereby bent outwardly, The bar thus produced is lightin weight, butis remarkably strong and rigid, being able to resist great strains and being especially adapted to bcemployed for making fence-posts and for `other purposes which will be suggested to those skilled in the art. p
My inventiongbroadly considered, is not limited to the rod with the spirally-projecting rib, but will cover described, but without bringing the edges together with. suflicicnt tightness to produce the rib.
l. As a new article of manufacture, a metal rod composed of a spit-ally wound and twisted strip of uniform thickness having a projecting spiral rib at the meeting edges, substantially as and for the purposes described.
2. The method herein described, which consists in twisting a strip of metal when cold into spiral form, bringing thereby its edges into contact, and bypressure of contactforming a. projecting spiral rib, substantially as and for the purposes described.
In testimony whereof I have hereunto set my hand this 24th day ot' Januar QA. I). 1891.
E DWARD L. CLARK.
