UNITE!) STATES GEORGE 'WALTHEBI. DAYTON, OHIO.
APPARATUS FOR GASTTNG STEEL WHEELS.
Specification of Letters Patent.
Patented May 30, 1922'.
Original application filed June 5, 1820, Serial No. 386,850. Divided and this application filed June 16,
To all to 710m itmay 0071 ccrn Be it known that I. Gnonen lVALTHnR, a citizen of the United Fitates residing at Dayton, in the county of )rlontgomery and State of Ohio, have invented certain new and useful Improvements in Apparatus for Casting Steel Vheels. of which the following is a specification, reference being had therein to the accompanying drawing.
My invention relates to casting steel wheels, and in particular to a method and apparatus for this purpose.
My apparatus and method are directed to meeting the problem of quantity production of cast steel wheels. primarily for automotive equipment. Tn order to facilitate this production, I have found it essential to reduce the number of operations in making the cores and to provide a ready means for assembling and disassembling the cores. It is also an object of my invention to use cores of either green or dry sand. It is possible by my. invention to use green sand entirely for the cores, forming the spokes and rims. It is another object of my invention to provide a method of manufacture which shall reduce the necessity for the employment of skilled. labor in casting wheels of this character.
Referring to the drawings, Figure 1, is a plan View of the supporting arbor, and the cores:
Fig. 2, is a plan view of a core carrying frame used for adjusting the units of the core in position;
Fig. 3. is a side elevation of a vertical section showing the cores in position prior to the casting of the wheel with the core carrying frame positioning the cores: and
Fig, 4:, is a View of a flask with the cores in position. showing in section the supporting arbors for the cores.
Referring to Figure 1. it will be observed that there is an outer ring 1 divisible at points 2-2 into segments, a complete set of segments completing the circle. To each segment of the ring is connected at an angle thereto the arbor 3 with projections 4 thereon to support the sand of the rim and spoke core 5. The bridges of the metal wheel forming a part of its outer rim are seen at 6--6 while the inner wall of the rim is at 7. The wall of the spokes is 8. The hub core is at 9, supported by the arbor 10. The arbor 10 of the hub and the arbor 3 of Serial No. 7S,132.
the spokes are connected to one another at 11 in any suitable manner.
The core for the spokes and rim and the hub is supported by the arbor 3 and is made up either of green or dry sand with them."- bor imbedded therein. 12 is a hook at tached to the segment of the supporting frame, the use of which will be described in connection with Figures 2 and 8.
Referring to Figure 2, we see an annular carrying frame 13 with handles 14-1 l. Across the frame are braces and support ing members 15. Centrally located is a clamping hook 16 rotated and thereby depressed or elevated by the hand wheel 17. The purpose of this hook is to clamp the arbor 10 and the arbor-s 3 to the frame 13, as will be more clearly seen in Figure 3. Above the members 5 is a central spacing block 18 which serves to assist in clamping the cores and their arbors in position. On the periphery of the ring 13, in Figure 2. will be seen another clamping hook 19 and its hand wheel 20 which is used to clamp in position the ring 1 seen in section in Figure 3. The hook 19 engages with the hook 12 on the ring 1 so that the clamping can be readily effected by rotating the wheel 20. Only one of these hand wheels and hooks on the periphery of the ring 13 is shown. Corresponding wheels are located on this ring for the other spokes depending upon the number of spokes. The installation shown is typical of the arrangements.
In Figure 3, 21 is the flask wall and 22 the sand suitably impressed by the pattern adapted for this purpose. to determine the location of the outer wall of the wheel. 23 is a positioning pin of the carrying frame. This pin passes through the aperture 24. in the lug 25 of Figures 2 and 3. This pin 23 projects through a spacing block 26 and aportion of the flask 21 at 27. By this standardized arrangement I am enabled with relatively unskilled labor to quickly position the respective elements of the cores, to utilize green sand and upon the casting of the wheel to withdraw the rings and the spoke arbors for use at another time. The hub arbor becomes an integral part of the wheel and is broken away upon the completion of the casting. The only loss is the hub arbor, new ones of which are employed for each of the castings.
In Fig. 4, is shown a flask, cores etc. in
m 1,411 see I desire to comprehend within the scope of my invention its equivalents and the modifications that are within its scope.
This application is a (.llVlSlOl] 01: my appli cation Serial No. 386,850 filed June 5,1920. Having thus fully described my lIlVBI1- tion, what I claim as new and desire to secure by Letters Patent, is:
1. In a core carrying trame, a ring, means to support a central clamping means, a spoke and rim core clamping means located on the periphery of said ring whereby the relationship of the. hub core and the spoke and rim cores may be maintained.
2. In a core carrying mechanism a ring, means of handling said ring, braces across said ring supporting centrally a depending hook and means to adjust said hook, a ph1- rality of hooks on the periphery of said ring, and means to adjust each of said hooks, a flask in which said cores are supported and means for determining the position of the hub, spoke and rim cores in the flask.
In testimony whereof I affix my signature.
GEO. W ALTHER.
