Description
I UNITED STATES PATENT QEEIQE.
MICHAEL GAFNEY, or NEWARK, NEW JERSEY.
IMPROVEMENT IN CORES FOR CASTING STENCH-TRAPS.
Specificationformiug part of Letters Patent No. 13?,133, dated March 25, 1873.
proved Stench-Trap (lore, of which the fol lowing is a specification:
My invention consists of a core of three parts, constructed as will be hereinafter described, for use in casting the cast-metal stench traps heretofore, and on the 31st day of October, 1871, patented to me.
Figure 1 is a section of the fiask and one of the parts of the core, and a side elevation of the other two parts. Fig. 2 is a side elevation of the part of the core shown in section in Fig. 1, and Fig. 3 is a section of the aforesaid improved trap as it comes from the mold.
Similar letters of reference indicate correresponding parts.
A is a large cylindrical core-piece for forming the interior of the shell B, and the exterior of the pipe 0 below the top of the shell A, and D represents a part or half of the flask in which the cores are all placed, and which forms the exterior of the whole of the trap. This said part A fills the flask completely at the end E, but it is recessed at F to make room for the thickness of the shell B, and in the upper end is a socket, G, for forming the outside of the tube 0, and from the bottom of this socket a hole, H, extends through core A for the prolongation of core I, around which both the parts 0 c are cast. This core Iis extended through core A to facilitatethe detaching of it after the casting by tapping the lower end with a hammer. K represents the core for the waste-pipe L; it is suitably fitted at the inner end against the side of the core A, as shown, to correspond with the angle it makes with said core A.
These cores, in connection with a flask of two parts, D, form the said traps, with the lower end open, which is afterwards spun or otherwise contracted nearly together by curving or drawing said end inward until a small hole remains, which is closed with a metal plug, in case it is designed to have the trap so that access may be had to the interior; or ifnot, the lower end may be wholly closed by contracting it as much as possible, and then finishing with solder. These cores may of course be used with sand molds, but I prefer to use a metal mold or flask in connection with them.
Having thus described my invention, I claim as new and desire to secure by Letters Patent-- The combination of the core-pieces A, I, and K, and a suitable flask or mold, D, substantially as specified.
