To @ZZ whom it may WHEEL.

Be it known that I, GEORGE TVVAIDIHER,

a citizen of the United States,

residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements inl/Vheels, of which the following is a specification, reference being had th ing drawing. y My invention rela erein to the accompanytes to wheels and in particular to the apparatus for cast wheels.

It is the object of a form of a hub core the present difficulty metal eating away the point of pourin lt has been by the turbulent my invention to provide which will elimina-te of the hot turbulent the green sand adjacent g the metal in the hub.

the practice to have green sand adjacent the hub core and spoke cores where the inet-al was poured.

dry sand pouring opening utilized but this was subject to being upset Sometimes liner was incoming met-al.

It is the object of my invention to provide a core portion which will prevent the contact of the incoming metal with the green sand, and w sand baked membe opening, a portion the hub and ill provide a hard dry r to form the pouring of the exterior walls of a portion of the inner ends of the spoke cores, all as a unit.

It is also possible asan additional advantage of my invention to provide for the manufacture facturing basis.

' It is also axles and bearings.

0f such members in quantity and in varying sizes so as duction of such cores to -put the proon4 a quantity manustandard sizes of iwheels in order to accommodate the different ductions of different proinanufacturers of Referring to the drawings: Fig. l is a section through a flask with a dry sand core and the Fig. 2 is a plan pouring member in eferring to the green sand in place; view of the dry sand question.

ably moulded to form the exterior of one i half of the wheel7 is a depression of angular character designated 6 in which is placed a ring consisting' of baked dry sand and designated 7, which forms the exterior of a portion of the spokes and hub. 8 is a. hub core located upon the green sand.

cope portion of these cores is designated'll. The inner ends of core ll designated l2 are yas a part of the exterior cap end hub mem.- bei' 13 which has a pluralityof radiating arms le and a pouring mouth l5. The chaplets 16 separate inner core ends l2 from cap 13 and position them although l2 and 13 form a (,:ontinuous structure otherwise. Similar chaplets form a similar function as at l?. The chaplets 17 determine the position of core 9 with respectto ring 7.

rllhe member 13 is provided with a series of shoulders 18 upon which the green sand 2O in the cope portion of the iiask rests. consequently, the green sand serves to maintain cap 13 in position. Cap 13 is positioned readily by its engagement with core 9 and ll through 12. It is also positioned by its engagement with the green sand 20. It cannot float upwardly to the green sand 2() being on top of a substantial portion of Being of hard dry sand it resists the eroding action of the incoming metal durine: the pouring of the wheel.

It will be understood that lr` do not desire to be confined to this specific adaptation of my invention, but comprehend within it suitable modifications which may be necessary in adapting it to varying condi,- tions.

Having thus fully described my invention, what i claim as new and desire to secure by Letters Patent, is:`

l. In a core member, a tubular member with a pouring` aperture therein. a stepped portion on the exterior thereof for engagement with green sand, and a cutaway portion on the interior thereof adapted to form the exterior of a hub of a cast. wheel.

2. ln a core member, a tubular member with a pouring aperture therein, a stepped portion on the exterior thereof for engagement with green sand, and a cutaway portion on the interior thereof adapted to forni the exterior of a hub of a cast wheel, a portion of said member being adapted to form formed f the inner ends of spoke cores for forming the spokes, and a portion of the hub of said Wheels.

3. In a core member, a tubular member with a pouring aperture therein, a stepped portion on the exterior thereof for engagement With green sand, and a cutaway portion on the interior thereof adapted to form the exterior of a hub of a cast Wheel, a portion of said member being adapted to form the inner ends of spoke cores for forming the spokes, a portion of the hub of said Wheels, andl chaplets between the hub portion of this core member and the portions serving as the inner ends of the spo-ke cores.

4. In a core, a cylindrical member having a plurality of separated arms radiating therefrom, a pouring tubular portion having an aperture therein, and means carried by said arms to serve as portions of the inner ends of spokecores, and means thereo-n for engaging therewith the inner ends of cope portions of the spoke cores.

5. In a core, a cylindrical member having a plurality of separated arms radiating therefrom, a pouring tubular portion having an aperture therein, means carried by said arms to serve as portions of the inner endsk of spoke cores, means thereon for engaging therewith the inner ends of cope portions of the spoke cores, and means on the exterior thereof for engagement with green sand to prevent the vertical and lateral movement of the member.

6. In combination in a flask With green sand in the drag portion thereof, an angular hub forming member of dry sand located thereon, spoke cores located thereon, a hub core member to form the exterior of the hub, and a portion of the spokes moulded as a unit on the inner ends of the member to form a portion of the inner ends thereof, said portions being in engagement With the drag and cope portions of the spoke cores.

7. In combination in a flask With green sand in the drag portion thereof, an angular hub forming member of dry sand located cores located thereon, a. hub core member to form the exterior of the hub, and a portion of the spokes moulded as a unit on the inner ends of the member to form a portion of the inner ends thereof, said portions being in engagement with the drag and cope portions of the spoke cores, said member having a passageway for the introduction of metal to the Wheel to be cast and means exterior thereof to prevent the lateral and vertical shifting of said member with which the green sand is in engagement.

8. In combination, a flask, a spoke core, a hub core and a hub cap core having a pouring aperture, and means integral therewith forming a portion of the inner ends ofthe spokes.

In testimony whereof, I aiiix my signature.

thereon, spoke GEORGE WALTHER.
