Description

J. L. CHAPMAN.
BRICK MACHINE.
No.1o4,268.
Patented June 14, 1870.
Ewen/i0 if? llntrd A gitanas @stent @titille JSEPH LQOHAPMAN, 0F PHILADELPHIA, PENNSYLVANIA, ASSIGNOL. TO.
HIMSELF AND JAMES BLEE STUART, 0F SAME PLACE.
Ltters Patent No. 104,268, dated J'zme 14, 1870.
I, JOSEPH `L. CHAPMAN, of the city of Philadel- 'phia and State of Pennsylvania, have invented certain Improvements in Brick-Machines, of which the i following is a specification.
The nature of my invention, in the irst place,.con sists of a. horizontal movable pressing-mold and 'stationary piston, combined and arranged with a hopper and i'illing-niold, the pressing-mold being moved by means of cams on a revolving shaft, and the movable pistou by means of a cinnk of the said shaft, as hei-cinafter'described.
In thesecond place, it consists of double horizontal-levers, and a plunger in connection therewith, for ieinoving the bricks from the mold, and an endless apron for the delivery of the same, the levers being opeinted by pins or cams on eachend of thesaid revolving shaft. The plnngeris then returned ro its upward position bymeans of springs'. The invention, in the third place, consists in the heating of the face'of the movable oi' pressing-piston, by means of steam through a pipe or pipes, in coniiection with a chamber of the piston, whereby the bricks are 4prevented from adheiing to the face of the piston. v
'.lo enable others skilled in the art to which niy'improvement appertans to make and use my invention, Iwill now give a. detailed description thereof.
In the accompanying drawing, which makes a' part 'of this specification,- 4
Figure 1 is aplan view of the improved machine.
Figure 2 vis a vertical section at the linexxof fig. 1.
Figure 3 is a side elevation.
Figure 4 is a horizontal section of the piston D. Likevletters in all the figures indicate the same parts'.
, A is the standing frame of the machine.
B-is the hopper from which the mold is charged with clay, there beings. receiving-chamber, C, beneath it, into which the clay fails when the movable piston D 4is drawn back into the position seen in full lines in g. 2. The said piston is operated by the crank E of the shaft F and connecting-rod G.
H is the pressing-mold, which' has a reciprocating movement by means .of the cams I I on the ends of the driving-shaft F and thel connecting-rods J J. Y
The mold is'brnght against the receiving-chamber C before the piston D is drawn to the rear side of the hopper B, and remains in that position until the clay,
in the forward motion o' the piston, is pushed through the said receiving-chamber C. Then, as ,the crank E bears' the piston still forward, for the condensation of the clay between it and the reacting stationary piston' D', the condensing-mold H is; moved forward over the' latter piston, at about onehalf the velocity of the movable piston D, to equalize the pressure on the two parallel dat faces of the bricks.
The positions which the movable piston and condcnsing-inold 'H assume when thc condensation of the clay is completed are represented by dotted lines iin-iig.
2. Tlre mold H is then still borne' forward into the position represented by full lines, and the brick is pushed out from between the pist-ons D and D' by the plunger K, connected with the side-levers L L, which have fiiIcrum-pinsua in the vert-ical stationary yokes M M, the rear ends of the levers being raised by the pins b b on the ends of the crank-shaft F, as the shaft revolves.
The levers, at their front cnds, have elbows d, which are connected by means of iivets or otherwise. To these elbows the plunger K is connected.
When the brick is pushed from between the pistons onto the endless removing-apron N on the rollers 0 O,
the plunger is' brought back to its former elevated position, as shown in the drawing, by means of -the spring I P, the front ends of the saine being conuected, by means of the links Q Q, with the elbows of the levers.`
The endless apron N is actuated by means of thc beit connected with the driving crank-shaft F and pulley S on one end of the shaft'l of one of the rolieis O.
Power is communicated to the drivingshaft F by 'suitable gearing in connection with the gear-wheel U.
To overcome the adhesion of the bricks to the press ing-piston D, I construct it with one or more chambers V, and connect therewith steam-pipes W, which are' supplied with steam from the generator of the enine.
g The horizontal 4parts e of the pipes should work in standing-boxes of the steam-pipes with which they are connected.Y
What I claim as new, and desire to secure by Letters Patent, is-
'.ilie`,combnation of theplunger K and levers L L,
' constructed and arranged substantially as described,
and operated by means of the springs-P I and crank shaft F, provided with pins oi; cams b b, as above set forth. 4
In testimony that the above is my invention, I have hereunto setmy hand and afiixcd my seal this 26th day of March, 1870.
