Original Filed Sept. 12. 1927 Fl ri [Ida/ ATTORNEY.
Patented Mar. 25, 1930 UNITED STATES PATENT OFFICE JOSEPH I]. DOSTAL, OI DETROIT, MICHIGAN, ASSIGNOR 'IO EARL HOLLEY, OF DETROIT, MICHIGAN CAST-IRON mom) Application filed September 12, 1927,.Seria1 No. 218,884. Renewed August 1,1929.
The object of this invention is to design adapted to moldhollow metal castings, apera mold suitable for use in the radiator moldforated core support whereby the gases gening machine described in the co-pending aperated within the cores are vented to the inplication, Serial No. 218,883,,filed September terior of the hollow mold.
5 12, 1927, of which I am one of the joint inventors.
Figure 1 shows the mold in elevation. Figure 2 shows a cross section on the plane 2-2 of Figure 1, with a radiator casting 1 shown in elevation.
The molds are arranged back to back, so that each mold contains two similar matrices or depressions, each depression being adapted to form half of a casting of one radiator section. The molds are adapted to'be poured V with the parting line in the vertical plane, and the mold inclined 30 to the position shown in the drawing. p
In the figures, A is the gate. B is the ma- ZOtrix of the mold. C D are the core supports.
The corresponding core supports on the right hand side are concealed by the casting shown in place. These core supports are perforated. E is the riser, which, when the mold is inclined is slightly below the top of the gate A. The purpose of this is to prevent the molds locking together, the riser E acting as a drain to remove any superfluous metal.
1 30 F G are the dowel pins, which enable the molds to be aligned together. H is the pin for moving the molds, the complete mechanism, of which this is a part, being disclosed in the co-pending application referred to. J is an arm extending from the mold to form a support, which is also described in detail in the co-pending application referred to.
In Figure 2 the casting is shown in place,
together with the sprue. The interior of the w mold is hollow, and is open at the sides and bottom so that the gases generated within the core escape freely through C D into the interior of the mold and so to the atmosphere. i
hat I claim is 1. In a double faced hollow radiator mold In testimony whereof I aifix my signature.
