FOUNDRY JACKET Filed July 15, 1940 'INVENTOR. JAMES F. HINES ATTORNEY.
Patented Feb. 10, 1942 FOUNDRY JACKET James F. Hines, Lakewood, Ohio, assignor to Hazel K. Hines, Lakewood, Ohio Application July 15, 1940, Serial No. 345,561
3 Claims.
This invention relates to the construction of mold containers, particularly jackets, and has for its principal purpose the protection of metal jackets from injury by molten metal either inside or outside.
For this purpose the present invention provides a composite jacketstructure combining the advantages of a metal jacket with those of a jacket of inherently fire resisting material, and also particularly arranged to shed spilled molten metal Without injury-to the sides. The material of the sides is usually aluminum or some other light weight metal of lower melting point than iron or steel, and hence subject to injury if the molten metal either breaks through the mold and contacts the wall from inside or is spilled and contacts it from the outside.
Further details and particulars of the invention will disclose its purposes and advantages more completely. It will be understood that the accompanying drawing and the descriptive matter following are illustrative of a preferred method and embodiment and are not to be taken as limitations.
In the accompanying drawing Fig. l is a perspective of a completed mold jacket made according to the principles of my invention;
Fig. 2 is an outer face elevation of an end wall of Fig. 1, enlarged;
Fig. 3 i an inner face elevation of part of the wall oflFig. 2, before the panel is placed;
Fig. 4 is an inner face elevation of part of the wall of Fig. 2, with panel in place;
Fig. 5 is a transverse verticalzsection on plane 5-5 of Fig. 2; and
Fig. 6 is a section corresponding to Fig. 5, but illustrating modifications.
Referring now particularly to Fig. 1, my mold container, illustrated in that figure as a jacket, comprises walls I, l, 2, 2 which are fastened at the corners in any suitable manner, and in the specific form shown are of lattice construction to lighten the weight. Aluminum is preferred material.
The specific side construction illustrated comprises a fram in which the framed opening has a lattice offset from the inner plane, as seen in Fig. 5, forming a recess for the reception of a panel of non-metallic fire resistant material, preferably some synthetic asbestos board, for example that commercially known by the trade name Transite. The upper edge 6 also has a top shed H inclined down and out at asharp angle, and interior and exterior relief as at l3 and I5 to lighten the weight. Since the Transite panel 9 runs well out towards the ends 5 and forms most of the central inner surface of the wall from top to bottom it is apparent that the parting line of practically any mold will be against the Transite and that opposite any place where the mold wall might probably be thin, with danger of the poured metal breaking through, the fire face of the container Will be the resistant material. A disadvantage of such materials is brittleness, but in the present construction the panels are easily replaced.
Injury to the exterior wall by spilled metal is avoided by the top shed II, which is preferably formed by having the side sufliciently thicker at the top than at the bottom to bring the outer edge of the shed I l on a vertical line with the plane of th lower exterior Wall face It, as seen in Fig. 5, or having the wall face below the edge of the shed recede, as at 16 in Fig. 6. The jacket corners project outwardly beyond the main portion of the wall, and are not shedded, neither are they protected by the panel, but the unprotected portions are not relatively large.
It will be observed that the present invention is not limited to a specific Wall construction, or to specific materials, but the drawing herein has been made from a commercial embodiment emphasizing light weight, and for that reason made of aluminum. Since the melting point of aluminum is 1214 F., whereas that of iron is 2795 F., and of foundry brasses from 1850 to 2350 F., it
o is apparent that protection of the jacket against burning is more important than when cast iron was a standard material for jackets.
The present invention is not limited to the specific form shown but is subject to modification within the principles of the invention as set forth in the appended claims.
I claim:
1. A mold jacket wall comprising in combination peripheral margins, a recess in the inner face of said Wall defined by said margins, and a panel of fire resistant material in said recess.
2. A mold jacket wall comprising in combination peripheral margins, a lattice connecting the 7 same, a recess in the inner fac of said wall into said lattice, and a panel of fire resistant material in said recess, the inner faces of said margins and of said panel being in the same plane.
3. A mold jacket wall comprising in combination a marginal structure including a top shed outwardly directed, corner flanges secured to said marginal structure and adapted for interfacial positioning each to eacharound the periphery of the container, and an interior panel of fire resistant material within said marginal structure opposite the parting line of molds for which said jacket is intended.
