Application filed March 13, 1905. Serial No. 249,778.

To all mil/0711, 73/; ntrty concern:

Be it known that 1, JOHN W. Ammason', a citizen of the United States of America, and a resident of Pawtucket, in the county of Providence and State of Rhodelsland, have invented certain new and useful Improvements in Driving-Cylinders for Spinning-Frames and Kindred Machines, of which the following is a specification.

My invention relates to sheet-metal driving-cylinders adapted in use to carry the cords or bands which transmit motion to the spindles of spi1mingframes and kindred machines.

:ln cylinders or drums of the class above referred to it is usual to construct them of a plurality of comparatively short sections, an end of each section being adapted to receive and be soldered. to the adjacent end of the fellow section and forming a flush or smooth joint and provided interiorly with a series of sheetmetal disks or partitions located contiguous to and soldered to the said joint portion. A journal or shaft is secured to and extends from the center of the outer ends of the cylinder, thereby adapting it to be revolubly mounted in suitable bearings. There are objections to such former sheet-metal driving-cylinders in that the percentage of labor and weight of stock entering into their construction materially increases the cost without corresponding advantages.

The object of my invention is to produce a driving cylinder or drum for s1')inniiiigmachines, &c., in which the weight of material, the amount of solder used, and also the cost of labor are considerably less than is required in the production of cylinders heretofore employed. My improved cylinder also possesses the added advantage of greater strength or stiffness and efficiency.

lln carrying out my invention each of the several cylindrical sections, or at least those comprising the main body portion of the cylinder, has one end thereof true and plain, the other end being inturned to form an integral interior peripheral flange, the adjacent outer portion of this end of the section being re duced in diameter a short distance longitudinally to receive thereon the plain or unswaged end of the fellow section. The adjacent or contacting surfaces of the thus-reduced and inserted end portions of the adjoining sections are then soldered together to form a practically air-tight or solid joint, the several sections when thus joined together form ing a cylinder having a smooth and straight exterior surface.

lln the accompanying sheet of drawings, Figure 1 is a side elevation, in reduced scale, of a driving-cylinder embodying my improvement. Fig. 2 is an enlarged longitudinal sectional view taken through the body portion of the cylinder. Fig. 3 is a partial cross-section taken on line 0 0 of Fig. 2. Fig. alis a cross-sectional view, enlarged, taken on line 1/; w of Fig. 1; and Fig. 5 is a longitudinal sectional view showing a slight modification.

A, referring to the drawings, indicates my improved driving-cylinder composed of a plurality of cylindrical sheet-metal sections a, soldered together and provided with end journals 7). The sections a are usually made of sheet metal, as tin, one end a of the section (see Fig. 2) being a continuation of the normal diameter of the cylinder. The other or opposite end portion of the section is swaged or reduced in diameter at a to a cylindrical form to receive thereon the adjacent end a" of the adjoining or fellow section. The stock or material of the front or outer end part of said reduced portion is turned inwardly and at right angles to the longitudinal axis to form the integral annular stlengthening-iiangef1 The operation just referred to may be accomplished by what is termed a metal-spinning process, wherein the said end portion is grad ually transformed by suitable tools from the cylindrical shape to form the inturned integral flange f. I would state that the thickness of stock used in making driving-cylinders A is considerably less than as represented in Figs. 2 and 3, wherein the thickness is exaggerated. The adjacent surfaces of the parts a a of the sections are united by solder in a well-known manner.

While I: prefer to make up the cylindrical units or sections a substantially alike-that is, each having one end reduced in diameter and inturned to form the stitl'ening member f, the other end being of normal dia1neter-I may provide one section with members a and f at each end adapted to receive thereon and be soldered thereto plain or unswaged sections 0, substantially as represented, section ally, in Fig. 5.

1 claim as my invention and desire to secure by United States Letters Patent In a sheet-metal driving-cylinder of the class described, the combination with a section or unit having a portion at one end thereof reduced in diameter and having the free end of said reduced portion bent inwardly at l gaging section a considerable distance from substantially right angles the longitudinal the end of said section, substantially as deaXis of the cylinder to form an integral an- 1 scribed.
