Nrrn TATES HENRY MARTIN, OF LANCASTER, PENNSYLVANIA.
BRICK-MACHINE.
SPECIFICATION forming part of Letters Patent No. 320,944, dated June 30, 1885.
Application filed May 1], 1885.
To all whom, it may concern:
Be it known that I, HENRY MARTIN, a citizen of the United States, residing at Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain Improvements in Brick-Machines, of which the following is a specification.
My invention relates to improvements in brick-machines in which a plunger operating in a pressingehamber forces the clay down into the molds, as shown in the improved brick-machine for which I obtained Letters Patent No. 83,297, dated October 20, 1868; and the object of my improvements is to prevent the clay from being forced upward between the sides and back of the plunger and pressing-chamber as the former descends to force the clay into the molds. I attain this object by the mechanism illustrated in the accompanying drawings, in which- Figure l is a front view, partly in section, of that part of my machine embracing the plunger and pressing-chamber. Fig. 2 is a vertical section through :20 x of Fig. 1. Fig. 3 is a front view of the main plate of the plunger and the filling-bars. Fig. is a front and end view, showing the manner of attaching the curtain. Fig. 5 is a front and end view of the wearing-strip of the gate, and Fig. 6 a front and end view of the filling-bars.
The top or main plate, A, of the plunger is fitted in loose grooved end filling-bars, B, which extend entirely across the end of the plate. The grooves b in these end bars are of suffieient depth to allow of considerable play of said bars between the ends of the top plate of the plunger and the end plates, 0, of the pressing-chamber. Below the grooves the inner edges of the said bars are beveled, so that the surface of the bevel slopes outward from the top plate toward the side of the pressingchamber, as shown at d. The result of this construction is, that as the plunger descends the reaction of the clay forces the fillingbars outward and tightly against the end plates of the chamber, thus preventing the escape of any clay.
In order to close the joint between the back of the plunger and that of the chamber, I hang a curtain or plate, D, of sheet metal against the back of the pressing-chamber. This curtain extends somewhat higher than the eX- treme rise of the plunger, and falls as low as the bottom edge of the back M of the plunger (No model.)
when raised to its greatest height. The curside of its back or bearing plate M, and as it ascends this clay is scraped off against the lower edge of the curtain, and packs in and forms a cushion between the plate D and the back of the chamber, filling up the space 00- casioned by the wear of the front of the plunger-plate. The back of the plunger-plate has a vertical bearingplate, M, made integral with and extending above it to close the opening N, leading from the pug-mill or chamber of the machine into the pressing-chamber.
In addition to preventing the escape of clay my device removes the great expense and trouble occasioned by the wearing of the edges of the plunger, which frequently requires to be replaced, by substituting therefor the removal of the worn-out bars and the cheap and easy attachment of sound ones.
What I claim as my invention, and desire to secure by Letters Patent, is
1. The combination, with a pressing-chamber, of a plunger with beveled filling-bars, having grooves adapted to receive the ends of the top plate of said plunger, substantially as herein specified.
2. The combination, with a pressing-chamber and plunger, of a curtain hinged at the top to the back of said chamber, and adapted by the outward pressure of its lower edge to fit tightly against the back part of the plunger-plate, substantially as herein specified.
3. The combination, with a pressing-chamber having a curtain hinged to its back plate,
of lugs projecting from said back plate over the top edge of the curtain to prevent the latter from being forced upward, as herein more fully specified.
HENRY MARTIN.
