UNITED STATES ANDREW BENSON, OF STERLING, ILLINOIS.

DISK WHEEL.

Application filed June 28.

To all whom 2'25 may concern Be it known that l'. Axonnw BnNsoN, a citizen of the United States. residing :1 t Sterling. in the county of llhiteside and State of l'llinois. have invented a certain new and useful improvement in Disk Wheels, of which the following is a full, clear, concise. and exact description. reference being had to the accompanying drawings, forming a part oi this specification.

This invention relates to improvements in disc wheels.

As is well known to those skilled in the art. sheet metal disc wheels possess many advantages over wood spoke or wire wheels used on automobiles. particularly because of the greater strength, longer life and more attractive appearance of the disc wheels as compared with the other types. There is a constantly growing demand for an etlic-ient disc wheel for automobiles and particularly one which may be substituted for spoke wheels that are furnished as standard with certain makes of automobiles.

One object or" my invention is to provide a sheet metal disc wheel of economical construction, durable, of relatively light weight and attractive in appearance.

More specifically, an object of my invention is to provide a disc wheel that may be readily substituted for spoke wheels now commonly used on certain makes of automobiles and with which disc wheel may be re-employed. without modification, the standard metal hub parts with such spoke wheels.

Other objects of the invention will more clearly appear from the description hereinafter following.

In the'drawing forming a part of this specification, Figure 1 is a diametrical sectional view of a disc wheel showing my improvements, the standard metal parts of the rear wheel of a well known make of wood spoke wheels being shown as they would be employed with my improved disc wheel. Figure 2 is an elevational view of the wheel illustrated in Figure 1. Figure 3 is a broken sectional view similar to Figure 1 illustrating the use of my improved wheel with the standard metal parts of a front wheel of a well known make of wood spoke wheels. And Figure 4 is a view corresponding to Figure 1 illustrating said well known make of wood spoke wheel.

In said drawing, the improved wheel is 1920. Serial No. 392,340.

shown as comprised principally of two sheet metal discs A and B and a rim C. The disc A is of larger diameter than the disc B and is flanged around its periphery as indicated at 10 to which is riveted or otherwise rigidly secured the rim (7. As will he understood by those skilled in the art, the rim C may be of any well known or desired type. that indi cated in the drawing being one which is now in very common use.

Each of the discs A and B is provided at its center with a hub opening and around said opening. the discs A and B are inwardly flanged as indicated at 11 and 12. Said flanges 11 and 12 are oppositely extended and have their edges abutting as indicated at 13. It will be noted that the central portions of the discs A. and B are spaced apart and extend parallel to points indicated approximately at 14-14. From the points 14, the two discs A and B are converged as indicated at 15 and are riveted or otherwise rigidly united as indicated at 16 around the periphery of the smaller disc B. Beyond the periphery of the smaller disc B, the larger disc A is reversely bent as indicated at 17 so as to extend in a plane forming substantially a continuation of the inclined or bent section of the smaller disc B. With this an rangement, a strong; and substantial hub is provided with a minimum amount of metal and the outer part of the disc A so arranged as to readily withstand bending, torsional and other strains that are imposed thereon when the wheel is in operation.

To hold the inner parts of the two discs A and B in properly spaced relation and also to additionally brace the same, I employ a circularly arranged series of hollow cylindrical spacers 18-18. The two discs A and B are provided with corresponding series of perforations, the perforations being defined by relatively narrow inturned flanges 19 and 20 which extend within the ends of the spacers 18 and hence hold the latter in proper position. Preferably, the interior of one end of each of the spacers 18 is slightly tapered as indicated at 21 and the corresponding inturned flanges 20 of the adjacent disc (disc B in the instance shown) formed to tit therewith.

Tn carrying out my invention. I make the diameter of the hub opening of a size to snugly accommodate the metal hub member 22 of a well known type of wood spoke wheel new used on, many thousands of automobiles. Furthermore, I make the overall thickness of the disc wheel at the hub correspond to the thickness the wood spokes 23 (indicated in Figure 4) which are used with said well known make of wheel. in this manner, the metal hub meniher which is provided with an inner flange 24 may be re-employed with my meta-l disc wheel as may also the outer detachable spoke-securing plate 25. it will also be understood that the spaces and openings in my improved wheel are located to correspond with the location of the bolts 26 used with the wood spoke type of wheel mentioned. The hub parts mentioned and the disc wheel are held. in assembled relatioinas is also the friction brake drum 27, by a plurality of bolts :28 of suitable size to fit the openings, said bolts being threaded at each end to accommodate the nuts 29 and 30, the latter being oil? a welllrnown term to exclude dust and dirt and provided with an inner hall face 31' cooperable with a corresponding washer 32.

In Figure 3, the metal hub 122 there illustratedand plate 125 are of the construction now commonly employed on the front wheels of the same make ct automobiles. The particular make of wood spoke wheel parts illustrated in the drawings is that of the Ford automobile but there are numerous other makes, now in use, with which. my disc wheel may be used in combination as will beiunderstood by those skilled in the art.

It will be obvious that the two disc parts of my wheel readily lend. themselves to manufacture by die-pressing operations and hence may be manuiactured in large quan tities at comparatively small expense. The disposition. Of the metal in the discs is such asto permit the use of relatively light gauge sheets without militatiim against the durability of the wheel under service conditions.

I- have herein shown and described what I now consider the preferred manner of carrying out the invention but the same is merely illustrative and I contemplate all changes and modifications that come within the scope of the claims appended hereto.

I claim:

1;:As an article of manufacture, a sheet metal wheel of disc type comprising: two

eas es discs, one of larger diameter than the other, each disc having a central hub opening and provided with a right angular inturned flange around said opening, the flanges extending in alinement in opposite directions and abutting, the portions of said discs adjacent said opening being arranged in spaced parallel relation and. convergingoutwardly thereof to the periphery of the smaller disc, the two discs being united around the periphery of the smaller disc. the larger disc being adapted to be provided with a rim; a perforated hub plate abutting the outer face oi the parallel portion of one of said discs; a hub member extending through said hub opening and through the perforation in said plate, and provided with a flange abutting the outer face of the parallel portion ot the other disc, the periphery of said hub abutting the alined inturned flanges of said discs; and securing means for clamping said discs between the hub plate and hub flange with the inturned right angular flanges bi said discs in abutting relation. l

2. As an article of manufacture, a sheet metal wheel of the disc type comprising: two sheet metal. discs, one of larger diameter than the other, said discs being provided with central hub openings and inturned flanges around the openings, the edges of said flanges abutting, said discs extending parallel adjacent the hub openings and then conyeying outwardly thereof to points at the periphery of the smaller disc, the two discs being united around the periphery of the smaller disc, the portion of the larger disc beyond the points where the two discs are united being extended in a plane forming substantially a continuation (if the plane of the outer portion of the smaller disc; and a circularly arranged series of spacers interposed between the parallel 'portione of the disc around the hub openings, each of said spacers having a central opening and the discs being perforated in alinementywith the spacer openings, the discs having narrow inturned flanges extending within the ends of the spacers.

In witness that I claim the foregoing I have hereunto subscribed my name this 14th day of June, 1920;

ANDREW BENSON.
