J. K. SAX. GAR WHEEL MOLD.
1 No. 496,100. Patented Apr. 25, 1893.
UNITED STATES PATENT OFFICE.
JOHN K. SAX, OF PITTSTON, PENNSYLVANIA.
CAR-WHEEL MOLD.
SPECIFICATION forming part of Letters Patent No. 496,100, dated April 25, 1893.
' ApplicationfiledOctoher 28. 1891. Serial No. 410,062. (No model.)
State of Pennsylvania, have invented certain new and useful Improvements in Molds for Making Oar-Vlheels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to an improvement in molds for making car wheels, the object being to produce an improved mold for use in the process of manufacturing my improved car wheel and it consists in certain novel features of construction and combinations and arrangements of parts as hereinafter set forth and pointed out in the claim.
In the accompanying drawings: Figure 1 is a plan View of the mold and Fig. 2 is a vertical sectional view, a portion being in elevation.
C, D, represent the upper and lower sections respectively of the mold, which sections are properly formed to cast the tread and front and rear faces of the rim. The mold is provided with a collapsible center E, composed of sections (Z, d, d, e, which are adapted to rest on an inwardly projecting flange e on the lower section D of the mold. The adjacent ends of two of the sections cl of the collapsible center are beveled and between these beveled ends, the similarly beveled section 9 of a hook i, is adapted to pass, said hook being adapted to engage the section e of the collapsible center and retain said collapsible center in place. The shank h is provided near its outer end with a slotj for the reception of a wedge-shaped key is for locking the hook. This mold is preferably covered on the inside with a coating of loam or black-wash, or both, to prevent the metal that is poured into the mold from cutting or washing away any portion of the mold. The mold is provided with a perforation, k, with which a cylinder Z is adapted to communicate. A plunger m is adapted to operate in the cylinder. A lever 72 is connected at one end to a post or upright 0 and at a point between its ends to the plunger m. This lever may be operated in any suitable manner to operate the plunger m to force the blow holes out of the mold.
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is- I In a mold for casting a car wheel rim or tire, the combination with the upper and lower sections, of a collapsible center, a perforated block projecting from one section of the mold, a hook adapted to engage one section of the collapsible center, the shank of said hook being adapted to pass through said perforated block and provided with a slot, and a Wedgeshaped key adapted to pass through said slot, substantially as set forth.
In testimony whereof I have signed this specification in the presence of two subscriblVitnesses:
W. S. LACK, P. K. RICHARDS.
