SHEET-METAL WHEEL.

Specification of Letters Patent. Patented Sept. 14, 1920.

Application filed July 23, 1919. Serial No. 312,731.

To all whom it may concern Be it known that we, ALFRED COTTON and LOUIE F. KoELLxER, citizens of the United States, and residents of Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Sheet-Metal lVheels, of which the following is a specification.

This invention relates to improvements in vehicle wheels, and has for ,its general object the provision of a light and strong metallic wheel having the hub and the rim thereof connected by a sheet metal web so constructed as to adapt the wheel to sustain heavy loads and to effectively resist torsional and lateral strains.

Another object of the invention is to provide a light but exceedingly rigid hub and rim connecting member or web for metallic wheels of the disk type which may be readily formed of light sheet metal. 7

A further object of the invention is to provide a connecting web or member for the hub and rim of a wheel formed by folding a blank of metallic stock to produce a web of general disk form having radial corrugations of considerable depth at the center of the web, said corrugations increasing in width and decreasing in depth toward the perimeter of the web, the axial depth of the corrugations at the hub being governed by the length of the portion of the hub available for connection with the web.

In the drawings; Figure 1 1s a side ele-.

Fig. 14 a vertical transverse section of the form of web shown in Figs. 12 and 13.

Referring to the various parts by numerals, l designates the hub of the Wheel, 2' and 3 the two sections of ademountable rim, and 4 a suitable pneumatic tire. The hub is preferably made of cast steel and the rim sections of rolled steel. The hub andrim are connected by a sheet metal web structure comprising an inner disk-like portion 5, an outer disk-like portion 6, and a sheet metal bearing sleeve or tubular member 7 extending through an axial opening in the web and welded adjacent its ends to the disk-like portion 6 and a driving spider 13 hereinafter described.

The disk-like portion 5 of the web is corrugated along substantially radial lines, said corrugations increasing in width and decreasing in depth toward the perimeter of the disk. The disk-like portion 5 of the Web is of general conoidal form, the summits of the ridges formed by the corrugations at the inner face of the wheel lying in substantially the same vertical plane throughout the length of the ridges. The outer disk-like portion 6 of the web is dished and the inner face thereof. engages the summits of the ridges formed at the outer side of the web portion 5 by the corrugations throughout the length of said ridges, and the portions edges. 'The welded members 5 and 6 and Fig. 6 a fragmentary section on the line sleeve 7 thus form a skeleton sheet metal conoidal rim support or web.

A series of blocks 9 are secured adjacent the perimeter of the web .at the inner side of the member 5, and a series of spacing members 10 are secured between the members 5 and- 6 in register with blocks 9. The section 2 of the divided rim is fixed to the sheet metal web by rivets 22 which pass through blocks 9, disk-like member 5, spacing members 10, disk-like-member 6 and the inwardly extending flange on rimsection 2.

The rim sectioh 3 is detachably held in place by bolts 11 which pass through the inwardly extending flanges on the rim sections and through apertures in the members 5 and 6 of the web and spacing members 10, and are threaded at their inner ends into the blocks 9. A metallic stiffening ring 12 surrounds the outer end of sleeve 7 and is welded to the outer face of the member 6 of the web.

A sheet metal driving spider 13 surrounds the inner end of sleeve 7 and is welded to said sleeve. The spider 13 is formed with radially extending fingers bent laterally toward the web and engaging in the grooves formed in the inner face of the web by the corrugations. The spider 13 is welded to disk-like member 5 of the web along the edges of the fingers of the spider. A metallic driving ring 14 is welded to the, face of the spider and surrounds the inner end of sleeve 7 between the spider 13 and a flange 15 formed on hub 1. T 0 form a driving connection between the ring 14 and the hub 1, the ring 14 is provided with apertures adapted to receive the heads of a series of bolts 16 passing through the flange 15 on the hub. The bolts 16 may be also utilized to secure a brake drum 17 to the hub. The entire rim-supporting structure, including the disk-like members 5 and 6, the spider, 13, rings 12 and 14, and tube 7, is removably held on the hub by a hub cap 18 with the driving rim interlocked with'the heads of bolts 16. '1 he hub cap 18 is formed with a beveled flange embracingthe stiffening ring 12 and is detachably held to the outer end of the hub by bolts 19 which are threaded into the end of the hub. A suitable dust cap 20 is threaded on the hub cap. member?) may be cut away as shown at 21 and 23 to reduce the weight of the web structure, if desired.

In Fig. 11 a slightly modified form of corrugated web member or supporting element is shown, said web member 5 being of substantially double frusto-conoidal form, the summits of the ridges formed by the corrugations at opposite faces of the member projecting laterally equal distances beyond the plane of the perimeter of the member. The web member 5 is adapted for attach: ment to a dished web member similar to web member 6 in the construction heretofore described to form a hub and rim connecting web. The web so constructed may be associated with a hub and rim in the manner shown in Figs. 1 to 10, or in any other suitable manner.

In Figs. 12, 13 and 14 still another form of web is shown. In this construction the .inner and outer members of the web are in- The dished form with a channel 24 therein adjacent the perimeter of the Web. The inner portion or member 26 of the web is provided with a central aperture 27 registering with aperture 25 in the member 24, and said inner member 26 is formed with radial corrugations increasing in width and decreasing in depth from the aperture 27 to the perimeter of the web. A stiffening or reinforcing ring 28 of rolled steel is confined in the channel 24, the inner face of said ring being flush with the inner face of member 24. Said shown in the previously described construction may be supported on the web, the member 2 of the rim being permanently secured to the web by rivets passing through apertures 29 in the web members and ring 28 and through the inwardly extending flange on the rim member. It will be obvious that,

if desired, the construction shown in Figs. 12 to 14 may be readily formed S0 that the summits of the ridges formed by the corruations at the inner side of the web would lie in the plane of the perimeter ofthe web, as in the construction shown in Figs. lto 10.

It will be obvious that various other forms of hubs, rims, and tires may be associated with either of the sheet metal web structures above described, and that either of the web structures may be secured to the hub and rim or felly members of a wheel in various ways. It will also be obvious that the several welded parts may be secured together in other ways such as riveting or brazing.

A feature of importance resides in the fact that by the construction shown a very rigid skeleton supporting web for the wheel rim is provided which is so constructed, and so connected with the rim and hub, that entrance of dirt within the wheel structure is impossible. A further important feature of the invention resides in the fact that the web is so formed as to provide a strong, but light, beam-like structure well adapted to withstand heavy, lateral, torsional and vertical strains, the corrugations being so shaped that the web comprises in effect a series of radially extending connected beams or columns of maximum width at the hub of the wheel.
