I MOLD CONTAINER Filed May 16, 1928 I E '3' James E'Hines Invento Attorneg Patented Feb. 3, 1931 warren STATES ATE T orrics a 7 JAMES F. HINES, OIE CLEVELAND, OHIO mom: coNrAI NER Application fired May 16, 1928. Serial no. 278,1271
The present invention relates, as indicated, to mold containers and amethod of making same. From time immemorial, found then, consists ofthe means hereinafter fully described and particularly pointed out in the claims.
description set forth in detail certain mechanism embodyingthe invention, such disclosed means constituting, 'however, but one of various mechanical forms in which the principle of the invention maybe used.
In said annexed drawings: r Fig. 1 is a perspective view of a mold container, certain parts having been removed for clarity of illustration, and a form being shown in dotted outline;;Figs. 2-and 3 are plan views of a fragment of said container, the facing members having been removed in Fig. 2;. and Fig. 1 is a horizontal section through the same fragment. :20 According to the present invention a form A shaped as a truncated pyramid is provided, and the container is built up about this form. In the said drawings, I have illustrated only a drag section, but it is tobeounderstood that the application. of the invention to the copesection of a flask or to a jacket or to any other mold container will be substantially the same. The form A is built of metal, and is provided with removmable abutments (not shown) which may be' placed at different points in the altitude of V i provided with aplurahtyof vertically spaced the form. v Theabutments having been properly located, a pair of drag side plates 11 and a pair of drag end plates 12 of proper dimen- V sions are assembledabout the form, their lower edges resting on the said abutments.
While it is desirable to have the sideplates 11 and end plates 12 of exactly proper dimensions so that their adjacent ends will The annexed drawing and the following be brought into close engagement when they i are so assembled on the form, such exact dimensioning is not absolutely necessary, -.as will appear hereinafter. The side plates 11 and end plates 12 are -'preferably formed of 5% cast aluminum, having their inner surfaces completely finished before assembly and each ofsaid members is provided at each end on its interior surface'with a recess :13 arranged to communicate with an'd to cooperate with the adjoining recess 13 of the adjacent; part. The side and end plates having been assembled in the above described manner, they are tightly clamped in position by any desired means, the lower ends ofthe recesses 13 are closed in a suitable manner and then Vmolten metal-is poured into the cavities defined-by the recesses 13 and the form A. Metal which is' so poured into the cavities may be leador Babbitt metal, but I prefer to use the same metal'fas that used in theplates themselves. Thus in the case above described, aluminum would be poured into the cavities. v The members .11, and 12 are allowed to" remain in .position clamped about-the form A untilthe metal l fhas cooled sufficiently to effect a firm and'permanent bond, retaining the members 11 and 12 in position as a unitary integral drag, indicated generally so at '15.- It will be noted that the inner face .of the bond metal 14 assumes a smoothcurve in accordance withthe shape of the form A. I
It will, be noted that the form A isof sufficient. height to permit the formation of; a
cope-section, thetside and end plates thereof the; upper edgeof the projections 16 which act to increase-the bond area between the metal 14 and the members 11"and' 12.. It will also be noted that the plates-11'andl2 are recessedas at 17 intermediate their. ends in order materially'to reduce the weight ofthe finished mold container. q j v n In order to protect the relatively softaluice minum of which the mold container is preferably formed, it is often advisable to provide facing strips of more resistant material for the upper and lower edges of the mold container. It may be preferable, therefore, to secure to the upper and lower faces of the mold container, strips of steel or similar resistant material. I prefer toprovide these strips as a plurality of abutting sections and not as a single formed piece. Thus, as in the illustrated embodiment, I may provide four corner pieces 18 adapted to span the respective joints of the container, together with two end sections 19 and two side sections 20.
As the strips are secured to the flanges 22 of the plates 11 and 12, and as each corner sec-' tion 18 is secured by screws 21 to one end plate 12 and one side platell, the corner pieces act as added reinforcements for the joints. 7 V p 7 Particular attention is calledoto the fact that the interior surface of each of the bonds 14 is flush at its edges with the interior surface of the abutting members 11 and 12, and intermediate its edges the same is rounded, whereby the mold container is formed with rounded rather than square corners. This is afeature of very great importance in that it materially facilitates the removalxof the mold container from the wall and the maintaining of a clean mold, a feature long recognized as desirable but heretofore accom plished, if at all, only by extremely expensive operations. These advantages are obtained according to the present invention merely by properly contouring the corners of the form A on which the mold container is formed.
The advantages, from a standpoint of time economy, of the above described method of forming mold containers, will be apparent. Attention should be called, however, to the fact that the above described method is fur ther advantageous in that it lends itself well to the building of outsize mold containers. Thus, for instance, if the mold A is designed primarily for building mold-containers of one standard size, it willbe possible to build upon said form mold containers of less size in almost any degree of difference,- merely by placing the aforementioned abutments at higher points in thealtitude'of said'forin.
Other modes of applying the principle of my invention may be employed instead of the one explained, change'being made as'regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of "such stated means be employed.
I therefore particularly point out and distinctly claim as my invention 3 v 1; In a moldcon'ta1ner,'a 1011113 comprising a pair of wall sectionstbutting at their ends and having recesses in'th'eir abutting ends cooperating toform a continuousrecess open to the interior of the container and lypartly in each of said members, projections extending into said recesses, and a tie cast in said continuous recess about said projections,
said tie having a rounded interior surface. Signed by me this 11th day of May, 1928.
