WILLIAM F. GAMMETER, OF CADIZ, OHIO;

TIRE-MACHINE DRUM.

Specification of Letters Patent.

Patented Mar. 2,1920.

Application filed August 16, 1919. Serial No. 317,914. a 1

To all whom it mayconcern:

Be it known that I, WILLIAM F. GAM- METER, a citizen of the United States, residing at Cadiz, in the county of Harrison and State of Ohio, have invented certain new and useful Improvements in Tire-Machine Drums, of which the following is a specification.

This invention relates to improvements in stock shells or drums and is designed more particularly as an improvement on the shell or drum shown in my Patent No. 1,104,296, issued July 21, 1914.

In the patented structure there is provided in each end' of the body of thedrum, a head having a polygonal opening to receive the polygonal shaft or spindle upon which the drum is supported and bywhich it is rotated, a tubular core beingfitted' at its ends to the said head and extending-axially within the drum to receive the said shaft or spindle and strengthen and reinforce the engagement between the parts. The present invention is directed chiefly to a novel means for securing together the said heads in the ends of the drum and the ends of the said tubular core whereby these parts will be rigidly united and securely. braced with relation to each other, the means provided for this purpose serving also in an effectual manner to prevent the heads be ing driven into the drum beyond their proper positions and to prevent the heads being pried or forced out from the ends of the drum.

Another object of the invention is to provide a connection between the heads and the ends of the core which may be conveniently secured at a low cost of production and which will serve in the most positive manner to secure together these parts,

In the accompanying drawings:

Figure 1 is a erspective view, parts being broken away, ilustrating a partially completed drum constructed in accordance with the present invention;

Fig. 2 is a vertical longitudinal sectional view therethrough;

Fig. 3 is an end elevation of the drum,

Fig. 4: is a perspective view of one end of the core before its connection with its respective head;

Fig. 5 is a transverse sectional view illustrating a modified form of core.

In the drawings the numeral 1 indicates in general the body of the drum which body is formed from sheet metal of the required gage and rolled to cylindrical form, the body being provided as is customary, in the manufacture of drums of my invention, with a longitudinally extending groove or c annel 2 to receive the end edge of the sheet 3 of rubber or other material to be wound upon the drum.

As in the patented structure, a head is arranged in each end of the drum and each of these heads, indicated in general by the numeral 4, comprises a substantially circular sheet metal body 5 having a peripheral flange 6 prO ecting from its outer face, the flanged periphery of the head being frictionally or otherwlse secured within the respective end of the body of the drum. This head may be positioned directly at the end of the drum or it may be spaced inwardlyfrom the end of the drum any desired distance. In order to receive the ends of the tubular core, the bodies of the heads 5 are formed centrally w1th polygonal openings 7.

In that form of the invention shown in Flgs. 1 to 4 inclusive, the core is formed in two sections and in the form shown in Flg. 5, it is formed in four sections. Also in each illustrated form the core is rectangular in cross section to receive a correspondlngly formed mandrel or shaft (not shown) although it will be understood that the shaft and core may have some other polygonal cross sectlon if found desirable and conseuently the core may be formed in more t an our sections without departing from the invention. In the drawings the core is indicated in general by the numeral 8 and in the two-part form comprises counterpart sections each having right angularly extending wings 9 which form two walls of the core, each wing being provided at its free longitudinal edge with an outstanding flange 10. When the sections are assembled, these flanges are disposed in contact and registration as shown in Figs. 1 and 4 of the drawings and are secured together by means of rivets or other suitable securing elements 11. The flanges 10 terminate short of the ends of the core so as to provide 0 positely located shoulders 12 spaced inwar 1y from each end of the core. In a line with the bend forming the juncture between the wings 9 comprising each section of the two-part core shown in Figs. 1 to 4 inclusive, each section is formed with a slit or incision 13 preferably extending inwardly from the end of the core the same distance that the shoulders 12 at the ends of the flanges 10 are spaced inwardly from the corresponding ends of the core. Thus at each end of each wall or side of the core there is formed a tongue indicated by the numeral 14:- In assembling the core with the heads 4, each end ofthe core is inserted into the opening 7 in the respective head so that the shoulders 12 will abut squarely against the inner face of the respective head. The tongues 14 are then struck down so as to bear firmly against the outer or opposite face of the said head 4, and rivets or other suitable securing elements indicated by the numeral 15 are secured through the said tongues and the body of the head, and these parts are in this manner permanently and securely united. As a result of this construction there are no rivet heads or other obstructions offered to the insertion of the shaft or mandrel into the core, the inner surfaces of the walls or sides of the core being left intact and unobstructed. It will be evident at this point that the engagement of the bodies or webs of the heads against the shoulders 12 serve effectually to prevent the heads being driven into the drum beyond their properly located positions, and on the other hand the tongues 14 serve efl'ectually to prevent the heads being driven out through the ends of the drum.

In that form of the invention shown in Fig. 5 inwhich the core is formed from four sections, each section indicated by the numeral 16, constitutes one side or wall of the core and each is formed at each of its longitudinal edges with an outstanding flange 17, these flanges corresponding to the flanges 10 and being secured together in the manner heretofore described. In this form of the invention all of the flanges will, of course, terminate short of the ends of the core so that .the web or body of each section will project at-its ends beyond its flanges to provide-tongues corresponding to the tongues 14.

Any suitable form of spider or bracing head 18 and any number of these heads desired. may be positioned upon the core and within the body of the drum so as to not only prevent the breaking down of the intermediate portion of the drum but also to prevent distortion or bending of the core.

Having thus described the invention, what is claimed as new is:

1. In a device of the class described, a tubular mandrel receiving core flanged longitudinally and receiving drum heads spaced apart with respect to each other by said longitudinal flanges, and means integral with said core and projecting through and en aging with said drum heads to per manentIy associate the same with said core.

2. In a device of the class described, a

tubular mandrel receiving core formed of longitudinally flanged connected abutting members and receiving drum heads spaced apart with respect to each other by said longitudinal flanges, and means integral with said core and projecting through and engaging with said drum heads to permanently associate the same with said core.

3. In a device of the class described, a tubular mandrel-receiving core having a longitudinal seam and provided at its seam with outstanding flanges terminating short of one end of the core, and a drum head fitted onto the core and engaging at one side against the said ends of the flanges, the core beyond the ends of the flanges being flanged against the other side ,of the said head.

4. In a device of the class described, a tubular mandrel-receiving core having a longitudinal seam and provided at its seam with outstanding flanges terminating short of one end of the core, a drum head fitted onto the core and engaging at one side against the said ends of the flanges, the core beyond the ends of the flanges being flanged against the other side of the said head, and
