CAST-METAL WHEEL.
Specification of Reissued Letters Patent. Reissue June 7, 1921,
Orjglnal No. 1,283,998, dated l ovember 5, 191a, smi No. 144,101,. filed January 24', 1917. Application tor retuue flleLlIovember 3, 1920. Serial No. 421,596.
T n all whom it may concern:
lle it known that T. (ll-nuns \Vanrnnn, a citizen of the United States of America. residing at Dayton, in the countyof Montgomcry and State of Ohio, haveinvented new and useful Improvements in Cast-Metal \Vhecls. of which thc'following is a specification.
This invention relates to certain improve-- ments in vehicle wheels such as are specially designed for motor trucks. The object of the present invention is to provide a wheel of increased strength and durability at the rim without'materially increasingthe weight thereof. In such a construction the spokes may be solid. or in other words,-the wheel may be built upor the spokes may be hollow and integrally united to the rim.
' 2 to facilitate the illustration. Fig. 2 is a sectional view on the line 2--2'of Fig. 1.
Referring in more particular terms. 1 designates the hub, 2 the. spokes. and 3 the rim, all of which are integrally united by being made in a single steel casting. The spokes 2 are hollow as is also the huh in order that a desirable degree of lightness of the structure shall be obtained and at the same tlme strength shall likewise be obtained in the structure. The spokes where 'they leave the hub 1 extend in broadly sweeping curves 4. andalso the outer ends of said spokes extend to the rimii in broadly sweeping curves 5. 66 are bolt holes for attaching a brake drum. The said spokes are provided with openings 9 through which the cores of sand used in making the casting may be removed from the spokes in a convenient manner'. This also very materially lightens the structure and saves just so much expense in machining because the periphery of these wheelsmust be carefully machined in order to fit the tire and its rim upon the wheel. 10-10 are bridges spanning portions of the rim and forming a structure to assist in su portin r the tire and in some instances t e rim. hese bridges are located in the neighborhood ofthe open end of the spoke and are formed with the depressions 8 which serve to save additional machining so that only thesurfaccs] need be machined. By the use of these supports 10 continuous supports are obviated, strength is given to the wheel sufficient for the purposes intended,
and space is left for the exit of the sandfrom the cores. used to formthe wheel. It will be observed that the periphery of the wheel is corrugated withalternate raised and depressed areas, as at 7. and 8. In the drawings, three such annular depressions are shown and four annular corrugated surfaces, but it will be understood that they may vary according-to the width of the rim or in accordance with the size of the depressions or conditions of foundry practice. It will also be understood that the bridges may be located in such positions as may be deslred to accomplish the above purposes.
ll bile I have shown and described certain features as constituting my invention, it will be understood that parts have been shown for purposes of illustration only, and that I do not desire to be limited to such details, as obvious modifications will occur to a person skilled in' the art.
Having thus fully described my invention,
- what I- claim as new and desire to secure by Letters. Patent. is y 1. A metal wheel. the hub, spokes and rim of which consist of one integral casting and 'the hub and spokes thereof being hollow, the rim being of a single thickness 'of metal and provided with annular corrugations throughout itscircumference, substantially as described. v
2. In a metal ,wheel, hub, spokes and a rim, spaced bridges on said rim, separated by apertures communicating with the spoke ends, said bridges having portions of their surfaces depressed below the general level Of the rim.
3. ln amctal wheel, a rim with portions thereof below the surface of the rim and portions level with the surface of the rim.
4. In a metal wheel. a hub, spokes and a rim, spaced bridges on said rim Separated by apertures communicating with the spoke I ends. said bridges having a portion of their surface level with the outer surface of the rim and a portion of their surfiibe below said 'rugatiorfs disposed ciroumferentially arallel rimsurface. the bridges being supported by to one another with portions of saic corruthe side walls only of the rim. gations below the general surface of the 130- 1-0 5. In a metal wheel, a hub, spokes and a riyhery of the rim. v i 5 rim, spaced bridges on said rim separated by Intestimony whereof I affix my signature.
apertures communicating with the spoke 1 i I ends,,said bridges having a plurality of cor- GEORGE WALTHER.
