invention is to provide producinga cast metal wheel or a type whose construction shall remain unchanged in the essential particulars when it is necessary to adapt the construction to varying sizes of axles,bearmg, etc.
' At the present time, cast wheels, and in particular cast steel'wheels for automotive equipment, are subject to-tlie.ob ect1on that radical modlfications in the patterns must be made to particular typ which the whe' the desire of of the automotive equipment.
fiteach cast steel wheel to the e of axle and bearing with e1 is to be' fitted according to the individual manufacturer This: serious- 1y disturbs economical production in the foundry.
It is an object of my invention to provide means and process to produce 'a wheel of such construction which will reduce these difficulties to a minimum spokes and r1 dimensions in by preserving the m and hub in the exterior the same form, shape and dimensions for each type of axle and each width of rim. be made will b The only variation that will e in the width or": the rim and the interior diameter-0t the hub and the width of 1 the exterior diameter.
without disturbing." the In-my present invention I desire to'claim the means and process abled to produ ameters,'hub widths and varying rim dimenby which I anre'n ce' wheels of different hub'die sions with the same spoke core comprised of a single uni To this end I provide a one piece. spoke core which maybe used with hub cores of varying width application,

as set forth in my co-pending 363,941-1' and adapted to have'sections placed thereon at the rim portion of the of the rim and thereby wheel to vary the dimensions produce a wheel adequate to the capacity to which it'is to be applied.

'width and narrowed the internal diam'et'er of the hub. I I Fig-lids avertical sectional view ofthe flask, cores-and metal Wheel; H
Referring particularly to- Figure .1 show ing a section of a wheel producedfby my improved process, 1 is the outer periphery of: the rim, 2 is the wall of a slot cut inthe outer periphery which is bridged at in tervalsby the bridges 3 3. '4 is a spoke whose outer ends merge into an-arch with the rim marked 5 in Figure 3.- The wall t offthe spoke hasa supplementary rib 7 which serves as an additional support on the inside of the hub next to the vehicle for the inner hub-wall 6. This inner hub wall 6 proceeds outwardly to the outside of the wheel until it meets the face'of the outer wall 8 of the hub on the outside of the wheel. This wall 8 is supported and joined to the spoke 4: by a curving wall '9' whose curvature in this standard wheel and loca tion with respect to the spokes remains con- 1 In this'art'it has been found very desirable to have a uniform and standard hub cap which may be used with varying sizes of axles and I therefore varying sizes in the internal diameter of the hubs ofthelcast wheels.
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 wall9, therefore permitting, as shown in Figure 50f the use of the same hub cap with varying sizes of hub.
In my present invention, I have accomplished the result also of varying the internal diameter of the hub without disturbing the standard construction of the wheel. To produce varying diameters of the hub internally without disturbing the master patterns and the course of manufacture, I provide fillers of varying diameters to co operate with the master pattern whereby Varying internal diameters will be produced, ranging from the maximum diameter ofthe master core box itself to the minimum diameter secured by the use of the various tillers of varying dimensions, placed in the core box. Referring to Figure 2, 10 is the master pattern, 11 is a detachable hub piece of the pattern and 12 is another detachable hub piece. Hub pieces of varying lengths all fitting on the shoulders 1313 may be installed on the master pattern without modifying them to secure varying widths of" hio its length.
This pattern is used to form the impression in the sand which will determine the outside dimensions of the rim, spoke and hub width. I The internal. diameter of the hub may be varied to suit thede'sire of the manufacturer of the wheel without disturbing the curvature of the wheel at rin Figure 1. The walls 6-6 of the wheel are either brought closer together or put farther apart ac cording to the desire of the manufacturer to adapt his wheel to a particular axle and bearing. This results in a corresponding change in the length of the wall 8 and of course of the support 7. y
In the course of manufacture, it is essential to disturb the progress of manufacture as little as possible to secure varying types of l'hubs for varying types 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-of 9 and. projecting that wall outwardly, maintaining the the same face 8 and only modifying 8 as to where such a projection has taken place as shown by the dotted lines. The dottedlines 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. i 1 @To manufacture readily such a wheel, which can be thus modified in these particulars without disturbing the orderly course of quantity pr'oductioml employ a core for the hub, spoke'and rim of the cast wheel, which is made as follows:
Referring to Figu'ret, 14 'is a core box and 15 is a central portion of a core box This can be seen 111 Figure 5,
. ferent diameter of hub. '17 is the core thus formed and V 18 is core.
the parting line of the lVith the master pattern, I have determined the outside dimensions of the rim,
spokes and hub width of the prospective wheel.
lVith the arrangement in Figure 4, I have determined the inside dimensions of the wheel, having made the core 17 for that purpose. and 11 of F igure2,I vary the width of the hub and with the detachable fillers 16 of Figure 4, I vary the internal diameter of the hub.
Referring to Figure 6, itv will be-s'een that I have provided means for varying the dimensions of the rim of the wheel. 19 designates the wall of the drag portion of the flask and 20 the wall of the scope whichwill clamp together, as shown at 21.
The sand in'the drag is indicated at22;
Preparatory to pouring the metal the spoke core 17, which is made in one pieceas distinguished from the old segmental spoke cores, is positioned in the sand 22 and supported by the print 23 and suitable chaplets, adapted to be placed inthe openingsfiet. The desired size ofhub core as shown at 25, is then positioned with respect to the spoke core. In case it is desired to increase the width of the rim a series of supplemental cores26 are pasted on to the one piece spoke core 17, as shown at '27.-It will readily be seen that this'means ofi'n- With the detachable members 12 creasing the rim has great'advantage inithat also be utilized to reduce the amount of metal in the spoke at the hub portion of the wheel. i
It will be seen that the wheel'is maintained in its standarddimensions elsewhere,
that it can be readily modified in the particulars which are necessary Without otherimum otn'ioditication ot the articies neces say to accomplish the desired object.
1 cesire to comprehend Within my invention such variations may be within its scope Without limiting myseit to the specific embodiments of it illustrated here.
This application is a division of my application Serial No. 380217 tiied May 10, 1920.
Having thus fully described my invention, What I ciam as new and desire to secure by Letters Patent, is 2- l. The method of forming; acore for use in casting Wheels with hubs of varying Width but having the same Wheel peripheral diameter which consists in making the major portion of the core in one piece and applying to said core members to vary the Width of the hubs ot the wheels to be cast.
