SETH iWILLlAMS, OF FOXBOROUGH, MASSACHUSETTS, ASSIGNOR TO -HENRY O. AND O. T. WILLIAMS, OF SAME PLAGE.
IMPROVEMENT IN MOLDS FOR CASTING CU'RVED PIPES.
Specification forming part of Letters Patent No. 511,826, dated May l5, 1866.
To all whom t may concern:
Beit known that I, SETE WILLIAMS, of Foxborough, in the county ot' Norfolk and State ot Massachusetts, have invented anew and useful Improvement in Molds for Casting Ourved Pipes; and I do hereby declare the same to be fully described in the following specification and represented in the accompanying drawings, of which- Figure lis a top view ot'a 1nolding-Iiask and core-stock as provided with my invention. Fig.
V2 is an end view, and Fig. 3 a side elevation,
and Fig. 4 a longitudinal section, of the same.
Heretot'ore there has been much difficulty experienced in properly adjusting and supporting in its mold the core of a curved pipe. Unless the core be arranged concentrically in the mold or matrix, the pipe will be of an unequal thickness, and consequently defective. To et'- i'cct the correct arrangement of the core, iron supports to suspend or sustain it in the matrix are commonly employed,such supports being retained in whole or in part in the pipe after the founding of it. It has been very desirable to tind some means of otherwise Iixing the core, such as will dispense with the iron supports. My invention enables me to accomplish this.
In the drawings, A and B are the two halve of acommon molding-liask, and C is the stock of the core, the remainder of the core consist ing of molding-sand applied to and duly formed in the stock.
The stock is to be made in the usual man ner, except it is to be extended so as to pass through two circular openings, D E, one of which is made in one end and the other in one side of the flask, one half ot each opening being formed in the upper and the other in the lower part of the flask. There are two brackets, F F, extended from the flask and with respect to each of the openings in manner as'represented.
The core-stock is formed, where it goes through each opening and between its two brackets, with four wings, a a a a, projecting radially from it and at right angles with'each other, the whole ot' the matrix prolonged would pass throughthe centers or axes of the two openings, we have only to lay the core-stock in the two halfopenings ot' the lower portion ofthe flask and next put the upper portion of the iiask in place, when the core-stock-will at once be brought into its correct position and be there held by the action of the openings, or the same and its brackets on its wings or extensions.
Vhat, therefore, I claim as my inven tion is The arrangement and combination ot1 the wings or extensions of the core-stock with the two openings, or the same and the brackets applied to the two parts of the flask, substantially as-specilied.
SETE WILLIAMS.
