UNITED STATE PATENT OFFICE.
EDiVARD K. COAS, OF PROVIDENCE, RHODE ISLAND, ASSIGNOR TO THE PROVIDENCE CYLINDER COMPANY, OF NASHUA, NEW HAMPSHIRE.
MANUFACTURE OF SHEET-METAL TUBES.
SPECIFICATION forming part of Letters Patent No. 378,769, dated February 28 1888.
Application filed May 16, 1887. Serial No. 238,331. (No model.)
To all whom it may concern:
Be it known that I, EDWARD K. Cons, of
Providence, in the State of Rhode Island,have
- object being to make a strong and rigid cylinder with greater economy than usual.
It is a common practice to make sheet-metal cylinders by spirally coiling over a suitable former a narrow strip of sheet metal, so that the edges abut each other, and then securing these edges by soldering; but on account of the continuous spiral joint these cylinders are not strong enough for many purposes.
My invention is illustrated in the accompanying drawings, in which- Figure l is a perspective view showing the strip wound to form a cylinder, and Fig. 2 is a longitudinal section of the same.
In carrying out my invention I take a strip or ribbon of sheet metal and bevel its edge faces through the entire length of the strip,the bevel given to the edge along one side being obverse to the bevel given to the edge along the other side. I then wind the ribbon A spirally,allowin g the edges to overlap each other, as in Figs. 1 and 2, the amount of lap being coequal with the beveled surfaces a c, to the end that the metal cylinder may be of even thickness throughout and the surface thereof be practically smooth and even. The metal thr0ughout,and is specially useful in running cotton-spindles, where speed and uniform motion are required.
I am aware that it has been suggested to form metal tubing by rolling the skelp with longitudinal ridges and furrows in its alternate edge faces, and lappiggthe same in a spiral direction to form a lock, and I do not claim this broadly, my invention being designed to enable me to make tubes out of very thin material, in which such ridges and furrows could not be made, and I therefore simply bevel the edges, so that the adjoining edges may overlap to form a bearing; and the whole is held together by subjecting the tube thus formed to a solder bath.
I claim The mode herein described of making a sheet-metal cylinder, consisting in coiling a ribbon of sheet metal having plain beveled edges to the form of a tube, with the bevels of the edges overlapping, and in subjecting the tube thus formed to a solder bath, substantially as described.
EDWARD K. cons.
