IMPROVEMENT IN APPARATUS FOR COMPRESSING CAST METALS IN LIQUID STATE.
Specification forming part of Letters Patent No. 145,325, dated December 9,1873; application filed September 27, 1873.
To all whom it mag] concern:
Be it known that I, HORACE W. BARNUM, of Omaha, in the county of Douglas and State of Nebraska, have invented a new and Improved Apparatus for Compressing Cast Metals in Liquid State, of which the tollowing is a specification:
In the accompanying drawing, Figure 1 represents a side elevation, partly in section, of my improved apparatus for compressing cast metal' in the liquid state; Fig. 2, a top view of the same; and Fig. 3, avertical central section on line 0 c, Fig. 2, of flask, cylinder, and ring.
Similar letters of reference indicate corresponding parts.
The object of my invention is to provide a portable convenient apparatus for solidifying cast metals in their liquid state by compressed air, which is forced directly on top of gate in flask after the metal is poured.
I do not claim to have originated the process of compressing metals when in the liquid state, but an improved apparatus for the purpose.
My invention consists of a portable reservoir for compressed air, with a pump attached, which latter is connected by rubber hose with a cylindrical cap that is fitted and clamped to a cylinder that is fastened to the top of flask, as hereinafter described.
In the drawings, A represents the portable reservoir, which is set on a platform, B, and provided with side wheels 0, to be moved to the required place. A pump, D, is connected with reservoir A, and serves to compress the air therein. A gage, E, on reservoir, indicates the pressure of the air therein. A shaft and,
handle, B, of platform B, allows the removal of the reservoir like a wheelbarrow. Reservoir A connects, by a strong rubber or other hose, A, with a cylindrical cap, F, with a stopcock, F, which regulates the action of the compressed air. Cap F fits nicely, by a rim, a, into-a corresponding groove, a, of connect ing cylinder G, which is firmly attached to the top of flask H by bolts, dovetailed sides, or otherwise. Both cylinders F and G are coupled together by projecting flanges b and clamps d. The flask-cylinder G is provided with a clay wash, and, previous to the pouring of the liquid metal, with a ring or cap-piece,1, set on top to prevent the hot metal from coming in contact with the clay wash.
The ring I is removed as soon as the metal is poured, cap F then clamped on cylinder G, and stop cock F opened, so that the compressed airv is let directly on top of metal through the gate of flask, compressing thereby the metal in the molds.
Having thus described my invention, I claim as new, and desire to secure by Letters Patent- 1. The combination, with the flask and cylinder H G, of the removable cap F, rubber pipe A, and movable air-cylinder A, and pump D, as shown and described.
2. The cylinder G and removable cap F, connected by rim and groove a a, and flange and couplings b d, in combination with the flask H, said cap and cylinder united forming a receiver for the air from the forcing appara tus, as shown and described.
HORACE W. BARNUM.
