FLASK FOR IVIOLDING METALS.
SPECIFICATION forming part of Letters Patent N0. 237,635, dated February 8, 1881;
Application filed December 6, 1880. (No model.)
and useful Improvements inMolds for'Oastihg Metals; and I do hereby declare that the following isa full, clear, and exact description thereof, reference being had to the accompanying drawing, and to the letters of reference marked thereon, making a part of this specification.
This invention relates to certain improvements in matrices and molds for casting metals by an improved process for which I have made application for Letters Patent of the United States.
The invention has for its objects to provide a means whereby the air at the face of the matrix maybe carried off by the entering` metal, and for the escape of the gases developed by the heated metal when poured into the mold, and thus obvi'ate the formation ofbloW-holesor bubblesaiid otherimperflections in the linished caslihg, especially at the faces or salient points of the same. These objects I attain by the apparatus more fully hereinafter specified and illustrated 1n the accompanying drawing, in which is represented a vertical section of a mold for carrying` my improvement into effect.
In carrying out my invention I form the matrix orilace of ,the mold of a composition of such nature as to receive the impressions of the pattern, or to have suitable impressions formed therein by cutting, earning, or otherwise, and which ywill b`e`suiiiciently refractory to resist the heat of the fluid metal and form a proper support for thesaine while cooling. Any substance or compound possessing the above-mentioned requisites may be employed; but for general purposes I have found a composition of the following ingredients, in the proportions named, to answer well, viz: Ground brick orporous clay, onepound; Whiting, one" half pound, and plaster-of-paris, one quarter pound, more lof the plasterof-paris being employed in casting the harder metals. rlhis composition I mountlonQsheet'supon a backing of glass or other vmaterial that is readily destructible under the influence of an intense heat, and
place such backing and compound in the lower part of a flask` lledwith sand, with the backing downwarcvand level ohi'the surface of the sand even with the surface of the matrix which is to form the faceof the nished casting. rIhe upper part of the flask is filled with sand in the usual manner, a recess being left to receive tlie metal forming the body of the casting. At oneside, on aline with the faceof the matrix, is formed a gate, through which 6o the metal is poured, and at the other side a pool or receptacle, into which the molten metal may escape asit iiows over the1 matrix in the mold, the air and gasesmat the face of the matrix escaping through the upper part of the pool or receptacle, thus permitting the metal to form and cool on the iacewofrtheniatrix gradually as the metalis poured into the mold, While the air will be excluded, thus insuring a perfect face to the casting produced. In order to permit the escape.. of the developed gases the body of the' sand below the glass or destructible plates is perforated by'means' of a suitable instrument in such manner as to form a series of supports or pillars for said glass or plate, and at the same time provide numerous passages for the gas developed by the hotvmetal, which breaks or destroys the glass or destructible plate sufficiently for the passage of the gases through the same, The said passages may extend partly through the body of sand, as indicated, in which case the gases will be diffused through the sand, or they may extend entirely through the sand, so as to permit the gases to escape directly into the atmosphere.
In the drawings, the letters A Al indicate the upper and lower parts of the flask, respectively, and B the destructible plate, of glass or other material, carrying on its face the matrix C. Y
D indicatesthe space between the upper and lower iiaskspvfnrmed in the sand in which the molten metal, and provided with nir-passages for the escape ot' gases, :md with a gate or sprue and receptacles for the superuous met/nl; neither do I olnini the matrix with its frangible backing and the passages in the mold for the escape of gasesls sueh forni the subjeoomntter of another application for Letters Patent tiled by 'me December 8, 1880.
Having thus fully described my invention, what I olnim7 and desire to seoure by Letters Patent., is-
1. A matrix for oastingmetnls, composed of a facing of refractory material adapted to receive suitable designs and a backing frnngt ble by heat ofthe molten metal,substantially as and Jfor the purposes specified.
2. A mold constructed as described with a matrix having a backing frangible by the heat of the molten metal, and provided with n pool at one side for the reeeptionot the superfluous 2o oHAs. SNEIDER Witnesses:
