SPECIFICATION forming part of Letters Patent No. 677,120, dated J une 25, 1901. Application lsd April 25, 1899. Serial No. 714,352. (lilo model.)

To @ZZ whom it may concern:

Be it known that I, GEORGE W. CROSS, a citizen of the United States, residing at Carbondale, in the county of Lackawanna and State of Pennsylvania, have invented a certain new and useful Improvement in NVheels, of which the following is a specification.

The object of my invention is to provide a wheel which shall be cheap and durable in manufacture and eflicient in operation.

The invention is applicable to wheels designed for many different uses, but will be herein described as applied to a wheel for cars, locomotives, or other similar vehicles. Such wheels are commonly formed of cast and wrought metal, often in several parts, which are' bolted or otherwise secured together. Not only is such a method of construction expensive and time-consuming, but the resultant wheel by reason of the jarringr and shearing of the bolts lacks the desirable element of durability. Again, wheels have been formed with cast rims or tires and hubs, the former being shrunk upon webs of wrought metal secured to the hubs. These also lack the element of durability. In both types no provision (save the toughness or resisting qualities of the metallic rim or tire) is made against the cracking, splitting, or chipping of portions of such rim-or tire adjacent to the tread of the wheel.

In accordance with the present invention I employ a hub and a rim or tire, preferably of tough cast metal, and these are joined by an intermediate web either single or double and preferably of wroughtsteel. The latter is provided with outwardly-projecting perforated tlanges both centrally and peripherally. About these are cast, respectively, the hub and the rim or tire, the cast metal surrounding the flanges and passing through the perforations therein, so as to form an intimate and in practical eect homogeneous union between the several parts without the aid of bolts or other similar securing devices.

The invention is illustrated in the accompanying drawings, in which- Figure l is a central section, and Fig. 2 a partial elevation, of a wheel embodying my invention. Fig. 3 is a central "section, and Fig. 4t a partial elevation, illustrating a modiication.

Referring particularly to the wheel shown in Figs. 1 and 2, A A designate a two-part web, preferably of steel plate. Each part is centrally perforated, that portion of the web adjacent to the center being flanged outwardly, as at u. a', and the outwardly-flanged portion is provided with depressions or perforations CL2 a3. The web A A is also provided with peripheral iianges B B', these iian ges having depressions or perforationsb b'. In the case of the part A of the web the flange B extends outwardly at approximately a right angle to the longitude of the wheel. In the case of the partvA of the web, however, the perforated and flanged portion should, in my belief, followihe form of the'subsequentlyapplied rim or tread. The flanges B of this member extend, therefore, outwardly in substantially the same plane as the liange B and then upwardly in substantially the same plane as the body of the part A of the web.

The web A A', constructed as described, having been provided, the hubs D and rims E, are then applied. These, as before stated, are preferably of tough cast metal. The web is so placed that its center and periphery shall project into the hub and rim molds and the molten metal run into the latter. InA assuming the permanent form such metal will pass through the perforations or into the depressions of both hub-liangcs and rim-flanges, permanently binding the Whole structure together.

The embodiment of the invention illustrated iii-Figs. 2 and 3 is substantially the same in general characteristics as that already described and contains the same principle. Here, however, a one-part web O is employed, and this is provided both centrally and peripherally with outwardly-extending anges formed in sections, certain hub-sections c extending in one direction and the others, c', in the opposite direction. The same is true as to the peripheral flange-sections c2 c3.

I do not herein claim, broadly, a wheel in which the hub and rim are cast upon a centrally and peripherally perforated plate, the essence of the invention being the Hanging of the perforated central and peripheral portions, as herein described. It should also he understood that by the Word perforation I do not necessarily imply that the openings IOC d2 a3 b b extend entirely through the flanges, although I deem this preferable, and that by the Word web is meant the portion of the Wheel intermediate of the hub and rim, regardless of Whether this be of one or more parts.

What I claim isl. A Wheel having a web provided with a i central flange, a hub cast about and surrounding such ange, and a rim or tire, substantially as described.

2. A Wheel having a web provided with a central perforated fiange, a hub cast about and surrounding such ange, and a rim or tire, substantially as described.

3. A Wheel having a web provided with Voppositely-turned flanges, a hub cast about and surrounding such flanges, and a rim or tire, substantially as described.

4. A Wheel having a Web provided With oppositely-turned perforated flanges, a hub cast about and surrounding such flanges and a rim or tire, substantially as described.

5. A Wheel having a Web provided with oppositely-turned, separated flanges, a hub cast about and surrounding such flanges, and a rim or tire, substantially as described.

6. A Wheel having a web provided with a peripheral, perforated flange, arim or tire cast about and surrounding such fiange, the material of said rim or tire extending into Vor through the perforations therein, and a hub, substantially as described.

7. A Wheel having a Web provided with peripheral, oppositely-turned flanges, a rim or tire cast about and surrounding such iianges, the material of said rim or tire eXtendinginto or through the perforations therein,and a hub, substan tially as described.

8. A Wheel having a web provided with peripheral,separated,perforated lianges,a rim or tire cast about and surrounding such flanges, the material of said rim or tire extending into or through the perfor-ations therein,and a hub, substantially as described.

9. A wheel having a web provided With peripheral, separated, oppositely-turned, perforated flanges, a rim or tire cast about and surrounding such flanges, the material of said rim or tire extending into or through the perf orations therein, and a hub, substantially as described.

10. A Wheel having a hub and a rim and a or flanges embedded in said hub, and a peripheral, perforated flange or flanges embedded in said rim, substantially as described.

13. A Wheel having a web provided with perforated, central and peripheral flanges, and a hub and a rim cast about and surrounding such central andperipheral fianges respectivel y, substantially as described.

14. A wheel having a hub and a rim, and a web provided With oppositely-turned flanges embedded in said hub and rim, substantially as described.

15. A wheel having a hub and a rim,and a web provided with oppositely-turned, perforated flanges embedded in said hub and rim, substantially as described.

16. A Wheel having a hub and a rim, and a web provided with a perforated flange or flanges projecting first outwardly and then upwardly from said web and embedded in said rim, substantially as described.

17. A Wheel having a hub and a rim and a Web provided with a flange or fianges embedded in said rim and conforming generally to the contour of the operative surface of said rim, substantially as described.

18. A Wheel having a hub and a rim, and a Web provided with a perforated liange or flanges embedded in said rim and conforming generally to the contour of the operative surface of said rim, substantially as described.

This specification signed and witnessed this 21st day of April, 1899.
