Application filed September 29, 1914. Serial No. 864,125.

To all whom it may concern:

Be it known that I, FRANKLIN MACK, a citizen of the United States, residing at Onaway, in the county of Presque Isle and titate of Michigan, have invented new and useful Improvements in VVheel-Rims, of which the following is a specification.

This invention relates to wheel rims and more particularly to the rims of the steering or controlling wheels of automobiles, motor cars, motor trucks and the like, the object of the invention beingto produce a particularly strong and durable rim of the character referred to which is sectional in construction in the initial manufacture thereof, the sections being of such a character and relation to each other as to form a rim equallyas strong as though it were made in one plece.

With the above and other objects in view, the invention consists in the novel construction, combination and arrangement of parts, as herein described, illustrated and claimed.

In the accompanying drawings :Figure 1 is a plan view of a rim embodying the present invention. Fig. 2 is an edge view of a sufficient portion thereof to illustrate the character of the sections and their relation to each other. Fig. 3 is a perspective view of one of the sections in the rough.

The-rim contemplated in this invention is composed of any desired number of sections which are arranged in two circular series, the sections of one series being arranged tooverlap and break joint with the sections of the other series and each section ofboth series being provided with a dovetailed extension and dove-tailed recesses at opposite sides of said extension and in the opposite end portions thereof, said recesses when in complemental relation to each other serving to receive the dove-tailed extension of an abutting and overlapping section of the opposite series.

In the manufacture of the rim, I make up each of the sections in the manner illus trated in Fig. 3 in which it will be observed that the section is of arcuate shape, and'embodies the main body portion 1, and the dovetail shaped extension 2 having the undercut edges 3 at the opposite extremities thereof, the formationof the dove-tailed extension 2 providing recesses 4 at opposite ends of the extension 2 and in the opposite end portions of the section. Two series A and B of said sections are used in the construction of each run and the two series are brought together in overlapping relation as shown so as to break joint at the point midway between the ends of the extension 2 of the adjacent section of the other series. When the two series are thus combined, the dove-tailed extensions 2 of one series alternate with the dove-tailed extensions 2 of the other series, the adjacent recesses 4 of two adjoining sections forming, in complemental relation to each other, a complete recess of the exact size to receive one of the dovetailed extensions 2 as clearly shown in Fig. 2.

While the extreme edges 5 of the sections 'may be brought together and glued in abutting relationv to each other, it .is found desirable in some instances to connect the extremities '5 of the sections by a scarf joint 6 shown in Fig. 2 as of zig-zag formation as this prevents the extremities of the sections from moving out of alinement with each other even though the glue should fail to hold. It will of course be understood that all of the sections of the rim are glued together wherever they touch thus forming a practically continuous glued joint extending entirely around the rim and it will further be understood that the scarf joints 6 are also glued. After the sections in the rough have been coated with glue and assembled and subjected to pressure and after the glue has become set and hard, the composite structure is turned in a lathe or the like and brought into the final finished condition illustrated in Fig. 1. It will be understood that all of the sections are exactly alike therefore requiring only one pattern or templet to work from. Either a plane or scarf joint may be employed as found desirable between the meeting ends of the sections of each series. Any material may be used in manufacturing the sections of the rim such as wood, metal or hard rubber.

What I claim is A wheel rim composed of two circular series of arcuate sections, each series forming one of a pair of circular wheel rim sections both of which are of uniform formation and diameter, the sections of one series In testimony whereof I affix my signature being arranged to overlap and break joint in presence of two Witnesses. With the sections of the other series and each section of both series being provided on its FRANKLIN MACK. 5 inner face With a dove-tailed extension, the "Vitnesses:
