Original application'filed May 10, '1920,"Seria1 No. 380,217. Divided and this application filed'flTune 16,
1921. Serial No. 478,131.
To all whom it may concern: I Be it known that I, GEORGE WAiarrnn, a citizen of the United States, residing at Dayton, in the countyof Montgomery and State'of Ohio, have invented certain new and useful Improvements inProduclng of Cast Metal lVheels, of which the following a is a specification, reference being bad therein I; to the accompanying drawing;
f My invention relates to the producing of cast metal wheels. 1 r i The object of my invention is to produce a cast metal wheel of a typewhose construction shall-remain unchanged in the essential particulars when it is necessary to adapt the construction to varying-sizes of axles, bearings,etc. At the present time, cast Wheels, andin particular cast steel wheels for automotive equipment, are subject to the objection that radical modifications in the patterns must be made to fit each cast steel wheel to the par- I ticular type of axle and bearing with which the wheel-is to be fitted according. to the desire of the individual manufacturer of the automotive equipment. :This' seriously disturbs economical production in the'foundryf.
It is an object of my invention to provide a wheel of such construction which will .reduce these difficulties to a minimum by preserving the spokes and rim and hub. in the exterior dimension in the same form, shape and. dimensions for each type of axle. The only variation that willbe vmade will be in the interior diameter of the hub andthe width of the hub withoutdisturbing the exterior diameter.
In my co-pending application No. 363,941 filed MarchB, I920, I-hav'e described and claimed a pattern for producing varying widths of hub, Y Y
In my present invention, I do not desire to'claim the construction of the Wheel thus produced but only the means'by which the Fig. 4, is a side elevation of -avertical sectionof the core box and a core withthe removable filler. i
Fig. 5, is a section of the standard hub illustrating by the dottedlinesa hub, ex-
tended which, while preserving the, outside, d mensions of the hub, has extended its width and narrowed thejinternal diameter of the hub.
Fig. 6, is a side elevation of avertical sec-1 tion of the flask, cores and metal wheel. Referring particularly to Figure l, 1 is the outer periphery of the rim, 2 is the wall of a slot cut in the outer periphery which is- I bridged at intervals by the :bridges 3- 3. {L
is a spoke whose outer ends merge intoan arch with the rim marked 5 in Figure 3, The wall 4 of the spoke hasasupplementary rib 7 which servesasanadditional support i I of the insideof the hub next to the vehicle for the inner hub wall 6., wall-6 proceeds outwardly the .wheel until it meets the wall, 8 of thehub on theoutside ofthe wheel. This wall 8 issupported'and joinecl to the spokev by the curving wall9 whose This inner hub to' the outside} of curvature in'this standard wheel andloca tion with respect to the spokes remains constant hile1thedistance between the Wall 6 face of theouter and 9, and consequently the length of the wall 8, varies according to the internal diameter of the hub. This-internaldiameter of the hub depends upon theparticularfaxle and hearing which may ,beused with this standard ,typeg'of wheel. e pon the face. of the wall 8 is mounted a hub cap. I
In this art it, has been found very desirable to, have a uniform and standard hub cap which maybe used with varying sizes-of axles and therefore varying sizes in the internal diameter of the hubs of the cast wheels. H
By my method of manufacture, I am enabled to project laterally the hub, to take varying lengths of axle without disturbing the, curvature of, the wall 9, therefore per,- mitting, as shown in Fig. 5 of the use of the same hub cap with varying sizes ofhub.
In my present. invention, I have accom plished the result also of varyingthe inter.- nal diameter of the hub without the standard construction ofthe wheel.v
To produce varying diametersof the hub i the shoulders 13-13 may be installed on the master pattern without modifying them to secure varying widths of hubs.
This pattern is used to form the impression in the sand which will determine the outside dimensions of the rim, spoke and hub width.
The internal diameter of the hub may be varied to suit the desire of the manufacturer or the wheel without disturbing the curvature of the wheel at 9 in Figure 1.
The walls 6 6 of the wheel are either brougl-it closer together or put further apart according to the desire of the manufacturer to adapt his wheel to particular axle and bearing. This results in a cor-respondingc'hange in the length of the wall 8 and of cores of the support 7.
In the course of manufacture, it is essential to disturb the progress of manufacture as little as possible to secure varying types of hubs tor varyingtypes of axles and bearings. It is also desirable to have the same external face for each wheel in order that the same hub cap and same odometer may be used for varying types of axles. with the corresponding variations in the wheels.
This is accomplished in my invention by maintaining the curvature 0159 and projecting that wall outwardly, maintaining the same face "8 and only modifying -8 as to its length. This can be seen in Figure 5, where such a projection has taken'place as shown by the dotted lines. The dotted lines show a construction of hub where the axle is longer and the clearance between it and the walls of the 'hub is narrower than that in the case of the axle and hub shown in full lines.
To manufacture readily such a wheel, which can be "thus modified in these particulars readily without disturbing the orderly course of quantity production, I employ a core for the hub,'spoke and rim of the cast wheel, which is made as follows:
Referring to Figure 1, 14 is a core box and '15 is a central portion of a core box which determines theminimum diameter of the hub The batter walls of '15 determine the position of the inner wall of 6 in the wheel. I also employ a filler 16 which may be used to increase the diameter of the hub between the walls 6-G. Fillers of the character of 16 fit around the master portion of the core at 15. These tillers always have the same internal diameter, but may be of varying external diameter, which will result in different size cores and therefore different diameter of hub. 17 is the core thus formed and 18 is the parting line of the core. with the master pattern, I have determined the outside dimensions oi the rim, spokes and hub width of the prospective wheel.
lVith the arrangement in Figure e, 1 have determined the inside dimensions of the wheel, having made the cores 17 for that purpose.
hub and with the detachable fillers 16 of Figure 4, I vary the internal diameter of the hub.
It will be seen that the wheel is maintained in its standard dimensions elsewhere, that it can be readily modified in the particulars which are necessary without otherwise disturbing the patterns, :eore boxes,
etc. and that my invention results in-a productive course of manufacture with the minimum of modifications of the articles necessary 'to accomplish the desired object.
In Figure 6, will be seen the walls of the flask 19, held together in the customary manner by the bolt 20. :21 is the sand in the flask, 22 is the hub core which is made of suitable sizes to suit the occasion. 1:? is the core and 1, '2, 3,4, 5,6, 5?, .8, and 9 designate the respectiveparts of the metal of the wheel.
In conclusion, the only changes that have to be made to fit the standard wheel towaried dimensions of axle and hearings will be .tochangeth'e ifiller l6 and the detachable portions of the master pattern 1 1 and 12.
I desire to comprehend within any invention such variations asmay be within its scope without limiting myseltito the-specific embodiments of it illustrated *here.
This application is a division of my. application No. 38021 7 filed 10,1920.
, Having thus fully described my invention, what I claim as new and desire-teasecure by Letters Patent, .is
1. The combination with a pattern dor ;a cast wheel comprising :a masterpontion-and a series of interchangeable hub .en'ds,-each of the same external diameter but varying one from the other in length; :o fla core box for a hub core -cOmpnising :a master portion and a serles of interchangeable fillers, each of said fillers varying from the others-aim external diameter and all of said fillers ibeing of the same internal diameter whereby they are adapted to fit interchangeably a common place on the master'core box, said With the detachable members 12 and 11 of Figure 2, I vary the width of the fillers further varying the one from the other in lengths corresponding to the def cast Wheel comprising a masterportion anda series of interchangeable hub ends, each of the same external diameter but. Varying one from the other in length; of'a core box for a hub core comprising a master portion and a series of interchangeable fillers, each of said fillers varying from the others in external diameter and all of said fillers bein of the same internal diameter whereby they are'adapted to fit interchangeably a common place on the master core box, therebeing right angle extensionson the ends of said fillers each of which varies in thickness but all of which are ofthe same'external diameter, the Variations of thickness in said ex tensions corresponding to the variations in length of the detachable elements of the master pattern.-
In testimony whereof, I affix my signature.
