SPECIFICATION forming part of Letters Patent No. 263,156, dated August 22, 1882.

Application inea March 10,1882. (No model.)

To all whom it 'may concern Be it known that I, EDWARD FALEs, of Keokuk, in the county of Lee and State of Iowa, have invented a new and useful Improvement in Brick Presses and Molds, of which the following is a full, clear, and exact description, reference being had to the annexed drawings, forming part of this specification.

l The object of this invention is to provide a convenient press and mold by which bricks equal in qualit-y to those manufactured by hydraulic pressure shall be produced at a less expense than the latter.

In the accompanying drawings, Figure l is a side elevation, showing one of the molds partly broken away. Fig. 2 is a plan view, in section, on line Fig. l. Fig. 3 is an end elevation, partly in section and Figs. 4 and 5 are details.

The press A is constructed with a platform, a, resting upon supports l), and two parallel standards, c, which are bolted to an intervening block, d, and secured to the center of the platform by means of bent rods c, passed over t the tops of the standards and through the platform, underneath which nuts f are screwed on the ends of the rods to bind the standards irmlyin position. In suitable bearingsformed in the standards is journaled a shaft, y, which is provided with a pulley, h, near the center thereof, for communicating power to the shaft. Instead of the pulley, any other suitable gearing may be substituted which shall be adapted to give the shaft eithera continuous rotary movement or an alternately reversing movement. Each end of the shaft g, which is to be made of any suitable diameter, is provided with a wrist, t', or with a crank, as the case may require, to which is connected a pitnian bar or follower, j, arranged in a vertical position, and having` a longitudinal slot, 7c, in its lower end, in which is placed a guide-plate, l, having one end adapted partially to inclose the bar, and thereby prevent its oscillation, and the other secured to the standard adjacent thereto. One of the wrists is placed more nearly in line with the longitudinal axis of the shaft than the other, in order that its corresponding pitman-bar, which is made somewhat longer than the other bar, shall have a shorter stroke than the latter when the proper motion in l given to theshaft. The object of this construction is to subject the material, which is to be held in a mold, m, to different degrees of pressure, as 4hereinafter described.

rEhe mold m consists of abcd-plate, n, to one side of which is secured an angular plate, o, and a similar angular plate, p, which formsa hingejoint with one end of the plate o, andis adapted to be closed against the latter to form a chamber to receive the material to be pressed. The plates o and p are provided with od'sets g at corresponding ends to enable the said plates to form a close joint with each other when closed.

As a means of securing the plates in a closed position, I- employ a slightly-conical pin, 7', which is inserted through a perforation in the bed-plate n, and through perforated intermeshing lugs s and t on the plates o and p, respectively. rlhe advantage of this construction is that a slight blow will suffice to remove the pin when the brick is to be discharged from the mold. A recess is formed in the plate p, adjacent to the lug s, in which a small instrument may be inserted to pry open the plate o, and a projection, u, on the plate p serves as a fulcrnm for theinstrument. The upper edges of the plates 0 and p are slightly beveled on the inner side to facilitate the entrance of a pressing-block, o, which is to` be of such a size that when the mold is filled to the top with material and the said block is placed thereon the mold and block will just pass under the pitmanbar having the longer stroke. It is designed that the pitman-bar havin g thelon ger stroke shall press the block t into the mold in suchmanner thatthe uppersnrfaces of theblock and mold shall be on a` level. The'mold is then to be moved as soon as the pressure is released by placing another mold at one side thereof and sliding both along the platform until the irst strikes against two sharp-edged pins or plates,w, secured to the platform, the said pins being so placed that they will not arrest the movement of the rst mold until the second is in proper position under the pitnian-bar. The rst mold is then to be transferred to the opposite side of the press and placed under the longer pitman-har having the shorter stroke, and a second pressing will be given to the material. As the material before the second pressing is already quite compact, it is IOU necessary that the bar used in the second pitman bar or follower and means for operatpressing shall have a shorter stroke, and the said bar is made longer than the other bar in order shall that it descend farther into the mold.

Owing to the great pressure exerted by the last or second step in the process, it is necessary to provide against straining the press, and I therefore construct the platform on that side with a yielding part consisting of a board or plate, gz/,supported upon spiral springs z, and connected to the platform by bolts, which are secured by nuts underneath the platform.

As a means of strengthening the connection between the standards and the shaft, I employ plates c', which are curved to iit over the shaft to act as a box, and a plate, a2, to take up wear, which plates are secured to the standards by bolts or otherwise.

In case it should be desired to produce bricks of less compactness of structure than that above provided for, both of the pitman-bars may be constructed so as to have the same length of stroke, and bricks be pressed by one operation. In this 4manner the capacity of the machine would be doubled.

The material which I use in constructing the bricks is fresh earth taken directly from the ground without any other process, ordinarily called dry earthj.7 such asis used in hydraulic presses.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. A dry-earth brick-press having a vertical ing the same, in combination with a mold having a solid bottom with hinged side and end vfor holding the material to be pressed, substantially as shown and described.

2. The combination ofthe platform, the standards, and the binding-rods with the shaft, the pitman-rods, and the guides, substantially as shown and described.

3. The combination of the shafthavin g wrists at each end, one of which is placed more nearly in line with the longitudinal axis thereof than the other, and the pitman-bars connected thereto and made of such a length, respectively,that the one having the shorter stroke shall begin its stroke from a plane at which the other ends its stroke, substantially as shown and described.

4. rIhe combination, with the mold and the pitman-bars having unequal strokes, as described, of the block fu, made of such a thickness that the mold filled with material to be` two similar angular plates, one of which is secured to the bed plate, while the. other is hinged to the rst and provided with a conical pin for securing the parts in a closed position, substantially as shown and described.
