L. NAPION. MOLD FOR MAKING PLASTER OR COMPOSITION OASTS.
Patented Apr. '7, 1891.
UNITED STATES LOUIS NAPION, OF
PATENT OFFICE.
CHICAGO, ILLINOIS.
MOLD FOR MAKING PLAST'ER OR COMPOSITION CASTS.
SPECIFICATION forming part of Letters Patent No. 449,945, dated April '7, 1891.
Application filed May '7, 1890.
To (all whom it may concern:
Be it known that ILLOUIS NAPION, a citizen of the United States, residing at Chicago, in the county Cook, State of Illinois, have invented a new and useful Improvement in Molds for Making Plaster or Composition Casts, of which the following is a specifica tion. 7
The object of my invention is to provide for economically and solidly casting plaster or composition ornaments of considerable size, such as center-pieces, cornices, 850.; and the invention consists in the features hereinafter described and claimed.
In the accompanying drawings, Figure 1 is a perspective view of the mold; Fig. 2, a vertical section taken in line 2 2 of Fig. 1; Fig. 3, an inside view of the shell and mold, and Fig.4 a side elevation of the screw or bolt and other parts.
A is the shell; B, the mold; O, the screws or bolts; D, an opening in the shell; E, longitudinal strengthening-strips, and F transverse strengthening-strips, of wood or other material; G, an extended horizontal portion at the lower end of the screw or bolt; H, a nut on the screw or bolt; I, aboard on which the mold rests; K, a cross-piece under the board to steady same, and L screw-presses to keep the mold and shell together.
Heretofore strips of wood, wire-cloth, &c., have been put in casts after the liquid material was poured into the mold, which strips were afterward allowed to remain in the cast to strengthen it. This way of putting in the strengthening-strips requires much labor, and generally is very inconvenient and unsatisfactory, this being especially so on concave or convex molds. By my invention the strengthening-strips, of wood, wire-cloth, or other material, are detachably fastened on the inner surface of the shell of the mold before the liquid material is poured in and afterward detached from the shell and allowed to remain embedded in the cast. The strengtheningstrips are secured to the inner surface A of the shell by screws or in any other suit- Serial No. 350,956, (No model.)
material except as to their upper surface, and in some cases even the upper surface is entirely covered. I prefer to secure the strips to the inner surface. of the shell by screws or bolts of the form shown, so that the horizontal projection at the lower end may by a partial turn of the screw be passed under and in contact with the strengthening-strips. In this way the horizontal portion of the screws serves to hold the strips in place, the strips being either horizontal or transverse, or both. After the liquid has been poured in and becomes sufficiently hardened to hold the strips in place without the aid of the screws the latter are turned sufficiently to remove the horizontal projecting portion out from under the strips and then pulled up close to the inner surface of the shell. This leaves the strips in such position that they become solidly em bedded in the cast whenever the same is It will of course .be understood that I do not intend to limit myself to the particular form of mold, shell, strips, or means for fastening the strips above described; but that I intend to vary the construction or to use other forms or equivalents, as circumstances may require.
1 claim 1. In combination with the outer shell or mold for making plasterer composition casts, strengthening-strips, and means for detachably fastening the same to the under side of the shell, substantially as described.
2. In combination with the outer shell and mold for making plaster or composition casts, strengthening-strips, and screws for detachably fastening the same to the under side of the shell, each screw being provided with a horizontal projecting portion at its lower end, substantially as described.
LOUIS NAIION.
