VILLIAM WOOD, OF HARTFORD, CONNECTICUT.

BRICK-MACHINE.

Specification of Letters Patent No. 16,561, dated February 3, 1857.

To all whom it may concernf Be it known that I, VILLIAM VooD, of the city of Hartford, county of Hartford, and State of Connecticut, have invented a new and useful Improvement in the Method of Construct-ing Machines for Making Bricks; and I do hereby declare that the` following is a full and exact description thereof, reference being had to the accom panying drawing and to the letters of reference marked thereon.

The nature of my invention consists in the peculiar construction of the press box, and grate.

To enable others skilled in the art to make `and use my invention, I will proceed to describe its construction and operation.

The drawing-Figure l is a front view of the brick machine. Fig. 2 a section through middle front to rear. Fig. 3 a plan showing arms &c. Fig. 4 a method of fastening the knives. Fig. 5, is an end section of the press box with the front J and slides turned up wit-h part of the front of the grate attached. Fig. 6 is a view of the press box with the front J turned up to show grate bars. Fig. 7 is a plan of the grate.

I construct the body and frame of t-he machine with wood and iron put strongly together of the required dimensions and form as described in the drawings Figs. l, 2, e, 4.

The vertical main shaft A is of iron with proper bearings, and mortises to receive the cutting and pressing knives B, these knives I fasten into the shaft in pairs with stop shoulders and keys as shown in Fig. L the upper eight knives I make to work flat and horizontally with a winding shape to cause them to press the clay downward while revolving and cutting, the lower six knives are the forcing knives and are made of a curved form flattened at the outer end to force the clay into the press and grate box c preparatory to being pressed through the grate, L, into the mold D.

On the upper end of the main shaft A I construct and fix arms E 2- 3 or 4L in number as the case may require, these arms are curved at the outer end and on which wheels or rollers may be fixed if necessary to strike against the vertical lever F, while in the act of revolving, pressing the same downward. This lever F passes through the shaft G, and is adjustable to a proper height,

by means of the screw to the saine to raise or lower it, to give more or less pressure, the vertical lever F being pressed down by the arm E, till it passes over the top of the same, causes the shaft. G to revolve a certain distance, and the segment pinion H, operates on the rack I, attached to the press plate K, and causes it to press downward in the press box c forcing the clay through the grating L into the mold D to form the bricks.

When the arm passes over the vertical lever it is relieved and rises again by the action o-f a weight on the side lever M, which operates the rock shaft Gr bringing up the press plate K again to be operated on by the following arm in the same way. I thus obtain the same number of pressures as there are arms at every revolution of the shaft A making six bricks at every pressure, the clay being constantly supplied into the box C, by the forcing knives B. The grating L is constructed to ft into the press box c, in such a manner as to be removed, to be replaced by another when different kind of bricks are required to be made. In the front of the press box at the bottom part, I make six slides or movable doors, S, to correspond with the openings of the grate. These slides are formed at the bottom edge inside to correspond with the grate bars and are beveled on the underside, when these slides are down the grating of course will be perfect. These slides being attached t-o swing front, J, of the press box, c, allow of the whole front of the press box being turned up together with the entire front of the grate, L, as shown in Figs. 5 and 6, or each slide S, can be raised vertically as shown in Fig. 1.

By the above construction and arrangement of the front of the press box and grate, any and all obstructions either in the press box or grate, be the same large or small can be quickly removed, and the ma# chine adjusted for use again. By this arrangement obstructions can be hooked from the grate in a much more convenientmanner than if the grate slides and box were of ordinary construction.

To take out a stone when it gets into the mold with the clay, it is only necessary to raise, the slide of the brick in which there is one. Sometimes however the bottom part being beveled as before stated, the st-one will force itself under and lift up the slide and come out with the mold without assistance. This preparation for taking out stones is very important, as they are injurious to complicated machinery and cause great delay and damage.

The mold platform N, I make with a series of rollers in the bottom for the molds tc slide on. I raise and lower the same by means of the screw, O, or it-s equivalent to accommodate the thickness of the brick to be made.

The empty brick molds are passed in the side of the machine at the opening, P, to the platform. rlwo are required to be in at one time. rlhe forward one is under the grating and press to be filled and the other one at the back. The lever P, passing under the platform to the back of the two molds presses both forward when operated on by 20 the foot', the empty mold forcing the full one out, to be taken away and the empty one takes its place to be filled. The lever is so balanced as to fall back immediately when the full mold is taken away and is relieved from the pressure of the foot, leaving the space empty at the back for another empty mold to be passed in.

Vhat I claim as my invention and desire to secure by Letters Patent is- Constructing the front of the press box 0, with the front of the grate L attached thereto, so that by means of slides S, and swing front J, a portion or all of the front of both press boX and grate can be raised in the manner and for the purpose set forth.
