GEO. O. HOUCK AND HENRY GORE, OF SPRINGFIELD, OHIO.

BRICK-MACHINE.

Specification of Letters Patent No.

To all whom it may concern:

Be it known t-hat we, GEORGE O. Houck and HENRY GORE, of Springfield, in the county of Clark and State of Ohio, have invented a new and Improved Machine for Molding and Pressing Bricks; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l, is a vertical section of our improvement taken in the line Fig. 2. Fig. 2, is an end view of ditto. Fig. 3, is a horizontal section of ditto taken in line (m) Fig. 1. Fig. 4, is a horizontal section of the mud mill shaft showing the manner is which the arms or beaters are attached to it. Fig. 5, is a transverse section of t-he vibrating frame below the mud-mill, and one of the boxes of said frame, showing the manner in which the pressing device, when necessary is rendered inoperative while the grinding or tempering device is in operation.

Similar letters of reference indicate corresponding parts in the several figures.

This invention consists in a novel device connected with the pressing mechanism whereby said mechanism may, when necessary, be rendered inoperative while the other' working part, viz., t-he tempering device is in operation.

The invention also consists in the peculiar means employed for presenting the molds to the press boxes and also for cutting olf the clay therefrom.

The invention further consists in an improvement in the mud mill whereby the bottom of the same and press boxes are relieved to a considerable extent of the pressure of the superincumbent clay and much friction thereby avoided and other advantages obtained as hereinafter shown.

To enable those skilled in the art to fully understand and construct our invention we will proceed to describe it.

A represents a rectangular frame the upper part of which is inclosed so as to form a box B. Two opposite sides of the box are inclosed by slides (a) (a) which may be readily removed or withdrawn when necessary for the purpose of cleaning the box, or repairing any of the working parts of the machine that are accessible from within it.

O, is a wooden shaft which is placed vertically within the box B and at its center. The lower end of this shaft is stepped in a 19,866, dated February 16, 1858.

cross piece (b) in the lower part of the frame A.

D, is an eccentric which is placed on the lower end of the shaft O. rlhis eccentric is constructed of metal, and it is placed within a frame E, which may also be constructed of metal. This frame is fitted underneath the bottom B, of the box B, and is formed of two broad end pieces (c), (c), connected by side bars (d), (d), see more particularly On the shaft O, a series of metal flanches or bosses (e) are secured. These bosses or flanches are provided With sockets in which wooden arms or beaters (f) are fitted in dove tail form as shown clearly in Fig. 4. Four flanches or bosses with arms attached are shown on the shaft C, in Fig. 1, but more or less may be used as desired. The upper end of shaft C, is stepped in a cross piece O.

Vithin the box B, and to its two opposite sides (g) (g) strips or ledges (h) (la.) are att-ached. These strips or ledges project a suitable distance from the inner sides of the box as shown in Fig. l and are attached to the sides (g) a short distance above their lower ends, and extend across the whole width of the sides.

On each end piece (c) of the frame E, a box F, is placed or iitted. These boxes are each formed of an upper and lower plate connected at their front ends by vertical studs each box having its front end (7c) connected to it by hinges or joints the upper parts of the ends (7c) being connected to the boxes as shown clearly in Fig. 1.

At the lower end of the box B, and at each side below the sides (g) (g) an opening (l) is made. These openings as will be seen by referring to Fig. 1, form recesses directly in front of the ends (lc) of the boxes F, F. To the outer sides of the side pieces (g) (g) of the box B, and directly over the opening (Z) metallic frames are secured, one over each opening. These frames are each provided with a grating (n), the openings of which correspond in size to the molds (0) as shown clearly in Fig. 3. G, represents a box of molds.

Within each frame (m) a sliding frame H, is iitted or placed. The ends of said frames being fitted in grooves (79) at the ends of the frame m). Each frame H, has

a horizontal wire (Q) fitted inA it, the ends of said wires being attached to springs (QW), said wires being attached to the frames H, at about their centers. To the upper part of n rods having each a spiral spring on them, the springs having a tendency to throw the rods outward. To the ends of the rods levers (bx) are attached, one to each, and to the upper side of plate (w) two screws (cx), (0X), are attached said screws passing through small ledges or uprights T o the lower part of each frame (m), (m), a metallic plate or shelf (ex) is jointed or hinged, as shown at (sx), and to projecting bars J, which are attached to the upper end of each frame (m) a catch K is secured, said catches being acted upon by springs (g) and levers (L) which are also attached to the bars J, as shown more particularly in Fig. l.

The end pieces (j) of the boxes extend along by the sides of the bars (cZ) ((Z), of the frame E. These end pieces (j) as well as the bars (OZ) have holes (c) made through them, and pins (Z) which are attached to bars L, L, pass through said holes securing the boxes F, over the ends (c) (c) of the frame E, springs (m) which are attached to the bars (cZ) (cZ) keeping the pins Z) in the holes, see more particularly Fig. 5. The boxes F, may be secured more or less over or on the end pieces (e), (e), in order to regulate the pressure as hereinafter described.

The operation is as follows: The boxes F, F, are first adjusted outward so as to close the openings (Z), (Z). The clay and water is then placed in box B, and power applied to shaft C, the arms or beaters (f) of which temper the clay. When the clay is properly tempered the boxes F, F, are adjusted farther back on the ends (c) (c) ofthe frame E, and these boxes will then have a reciprocating motion as they will move with frame E, which is operated back and forth by the eccentric D. As the boxes F, F, move back and forth they press the tempered clay through the frames (m), H, into the molds (0)-as soon as each box F, has reached the end of its outward movement and filled the molds (o), the catch I, below the filled molds is actuated by its screw (0X) and the frame H, of the filled molds is moved upward by its spring (t), the wire (Q) cutting off the clay and the lever (L) which is actuated by the upper end of the frame H, as it rises tripping the catch K, and allowing the plate or shelf (ex) to turn down by its own gravity, in connection with that of the box G of molds. As the plate (w) moves in one direction and one frame H, is released, the other at the opposite side of the frame A, is brought down owing to the connection of said frames with the plate (w) by means of the chains (u). And as the filled molds are taken from one shelf, empty ones are sanded and placed thereon, the shelves being turned up so as to be caught and retained by the catches K, until the molds are lled. By this invention it will be seen that the molds are filled alternately at opposite sides of the machine, and that the pressing device by adjusting the boxes F, as previously described may be rendered inoperative when the mud mill is to be operated alone. This is necessary at least when the machine is irst started as a quantity of clay must first be tempered before being formed into the molds. ll/Then however the first quantity of clay is tempered both the grinding and pressing devices may operate simultaneously the clay being gradually fed into the box B. The strips or ledges (ZL) in the box B, partially sustain the clay therein and consequently prevent it from oozing out through the opening (Z) when said openings are closed as tightly as may be by the boxes F. The hinged ends (Zr) of said boxes allow the air to escape from or pass freely through the boxes F.

Having thus described our invention what we claim as new and desire to secure by Letters Patent, is-

1. YThe boxes or followers F, F, applied to or fitted on the ends (c), (c), of the frame E, and connected thereto substantially as herein shown for the purpose set forth.

2. The hinged plates or shelves (cx) which receive the molds attached to the frame A, as shown and used in connection with the stationary frames and sliding frames H, provided with the wires (g) the whole being arranged to operate as and for the purpose set forth.

3. The sliding frames H, provided with the wires (g) or their equivalents and connected with the springs (t) in connection with the spring catches I, the above parts being arranged so as to be operated automatically from the reciprocating follower frame E, substantially as and for the purpose specified.

4:. The strips or ledges placed within the box B, substantially as and for the purpose set forth.
