PROCESS OF MAKING ARTIFICIAL-STONE ARTICLES.
Specification of Letters Patent.
rae-enten July 19, 1910.
Application filed July 8, 1908, Serial No. 442,525. Renewed June 3, 1910. Serial No. 564,858.
To all whom it may concern:
Be it known that I, ALBERT A. PAULY, a citizen of the United States, residing at Youngstown, in the' county of Mahoning and Stateof Ohio, have invented or discovered new and useful Improvements in Processes of Making Artificial-Stone Articles, of which the following is a specification.
My invention relates to the molding of cement or articles containing cement, having hardening or setting qualities similar to Portland cement.
It is the object of my invention to heat the molded articles while in the mold so that they may be removed from the mold in a much shorter time than that required when the hardening or setting is not hastened.
To be more specific', it is the object of the present invention to provide a method by which articles of uneven thicknessmay be heated substantially evenly.
I have shown my process in connection with the molding of hollow bodies but it is not 'confined to the same.
Referring to the drawings accompanying this specification, Figure 1 is a vertical section of an apparatus adapted to my process, an article being shown in the mold. Fig. 2 is a central vertical section of the upper part of Fig. 1, showing the article ejected from the mold.
1 represents an outer molding die, having its wall double to form the jacket 2 to contain water and steam for heating the molded article 3, which is shown as a sewer pipe. 4 is a water pipe having any desired number of branches 5 leading up through the bottom of the jacket Q and terminating at or near the bottom of the bell forming, or expanded portion of the die 1. Within the pipe 4 is the steam pipe 6 having the branches 7 which stand inside the branches 5 and have their upper ends within the jacket 2 and preferably somewhat above the j top of the branches j 8 is a hollow core vstandin,f ,r in the die 2 audhas' its top closed and its lower end connected to the water pipe 4 by means of the branch pipe 9. The branch steam pipe 10. connected to the steam supply pipe 6, preferably lies within. the branch pipe 5) and extends preferably nearly to the top 0f the core.
11 is a ring around the upper end of the core for forming the seat 12 of the sewer pipe.
13 1s a. cross-head supporting a number of stripper bars 14 which engage the under- The article being thicker in the bell below the seat 12 will not be heated or set so soon as the thinner body portion of the article below the bell.
Steam is introduced into the jacket 2 by means of the branch pipes 7 whose ends are preferably opposite the end of the pipe 10. The steam in the jacket heats the article 3 around the bell and assists the steam in the core to harden the thicker portion of the bell. r1`he water in the jacket. being at a lower temperature than the steam prevents the article below the water line from hardening as fast as it would in ease steam were used entirely in the jacket. The temperature of the water and steam can be regulated to harden the sewer pipe substantially evenly from end to end. The die may be thickened, if desired, as shown at 19 to make the upper end of the bell harden slower. The ring 11 and the thickened portion 19 retard the conduction of heat. This principle illustrated by the. portion 19 may obviously be extended to the walls of the die or the core, when it is desired to retard the conduction of the heat to the molded article.
The water in thcjacket may be heated in any desired manner before or after it is admitted to the same. Ordinarily steam in the jacket and core will be.- sufficient. The water of condensation runs down the branch pipes 5 and 9 and thence through the pipe 4.
The principle of my invention may be applied to the make of various kinds of articles by heating in any manner the'thicker portions of the articles thereof, whether by thickened walls, or by steam and water, or
otherwise.
