IMPROVED BRICK-MACHINE.

Specification forming part of Letters Patent No. 49,376, dated August 15, 1865.

To all whom it may concern:

BeitknownthatLEP.H.OA 1ioN,oSpringfield, in the county of Clarke and State of Ohio, have invented a new and Improved Machine for Pressing Brick; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to makeand use the same, reference being had to the accompanying drawings, forming part of this specification, in which-- 7 Figure 1 is a hoi izontal section of my-invention, taken in the line war, Fig. 2; Fig.2, a vertical central section of the same, taken in the line .3 3 Fig. 1; I ig. 3, a vertical section of a portion of the same, taken in the line z 2, Fig. 1; Fig. 4, a plan or top view of an annular-track pertaining to the same; Fig. 5, a side view of Fig. 4; Fig. 6, a side view of a portion or acireular table pertaining to the invention.

Similar letters of reference indicale like parts.

This invention consists in the employment or use of a horizontal rotating disk or table provided with cavities which form the brickmolds, and having plungers or follewers fitted within them, which are operated by inclined surfaces on an annular track or way. The cavities or molds in the disk or table are provided with hinged lids or covers, and an adjustable bearing is placed overthe lids or covers to keep them firmly down while the plunge'rs or followers are compressing the clay in the cavities or molds, the whole being constructed and arranged as hereinafter set forth.

A represents a framing, which has a horizontal bed-piece, B, attached to it, and C is a. shaft which passes vertically through the bedpieceB, and has a circular table, I), secured firmly upon it, in which a series of square cavities, E, are made, said cavities extending entirely throughthe table and forming the brickmolds. In each of these cavities E there is fitted a follower or plunger, F, having a friction-roller, Gr, at their lower ends, which rest upon an annular way or track, 11,011 the bedpiece B, said way or track having a concentric position with the table D. The way or track H is notof an equal height all around. It has an elevated portion, a, with an inclined plane, I) b, at its ends, said inclined planes tbrmiug the junction between the elevated portion gt ofthe annular way or track H, as shown in Fig,

4. The inclined planes 1) b are permanent or fixed, but in the lower portion, 01,01' the track H there is an adjustable section, I, connected to the bed-piece B by a hinge, c, and resting at its free or disengaged end on a set-screw, J, which passes up through the bed'piece B, as shown in Fig. 2.

The cavities or molds E are each provided with a hinged lidor cover, K, in each of whihh a friction-roller'is placed, and each lid-or cover has two arms, d d, attached to its outer end, as shown clearly in Fig. 6. These arms, as the table D rotates, come in contact with projectionsee on the framing and open and close the lids or covers K.

M represents a segment-bearin g, which is at tached to an adjustable horizontal bar, "N, on

the framing A,said bar N being regulated by set-screws f f. This bearing M is over and a short distance aloovethe top of the table D,

and is in line with the hinged or adjustable section 1 of the annular way or track H.

The plungers or followers F are grooved all around, as shown at g, to form oil-cavities to keep the plungers or followers properly lubricated. These grooves have pieces or strips of cloth j, or other absorbent material, fitted in them. (See Fig. 2.)

The inclined plane (1 atone end of the elevated portion a of the annular way or track has a metal plate, h, attached to it, the sides of which project beyond the sides of the inclined plane b, in order to admit of lips i '5 at. the lower end of the follower catching under the edges of plate h. By this means the plan-- gers or followers are drawn down in the molds as the former pass down the inclined plane I), and the lids or covers are thrown open previously to the plungers 01' followers reaching the inclined plane I), in consequence of the arms at of the lids coming in contact with the projection 0 on the framing.

The molds E are filledlwith clay while the plungers or followers are down and their rollers G are traveling over the lower portion, a,

of the way or track H, and as the filled molds pass along the arms d of their open lids section I. After the clay is-thus compressed the lids or covers K are thrown open in consequence of the arms d coming; in contact with the projections e, and the rollers G of the plungers or followers pass up the inclined plane b, and the plungers or followers are forced up ward and the compressed clay or brick discharged from thcinolds. The plungers or.fol-,

lowers are drawn down in the molds in passing down the inclined planes b, as previously' described, the molds filled, the lids or covers closed, and the pressure given the clay, as pre- Viously set forth. 1

I claim as new and desire to secure by Letters Patent-' I 1. The rotary mold-wheel or table D, in connection with a bearin M, and inclined adjustable section I, and rising and falling plungers or followers F, for thepurpose of molding or pressing brick, as set forth.

2. -The particular arrangement of the annular way or track H, section I, and the bearin g M, as shown, whereby the lids ot' the molds are held down by the hearing M, while the pressure is given by the section I, as described.

3. Arranging the section I asshown, or in any other equivalent way, so as to-render the saine capable of being adjusted toregulate the pressure on the clay in the molds, as set forth.

4. The friction-rollers G at the lower ends of the plungers or followers l5, and the frictionrollers 'L in the lids or covers K, for the purpose specified.

' 5. The hinged lids or covers K, provided with the arms (Z d, in connection with the projections e 0, attached to the framing, substantially as and for the purpose set forth.

I 6. The lips i i at the lower ends of the plungcrs or followers, in connection with the plate It, or its equivalent, attached. to the inclined planeb, for the purpose of lowering or drawing down the followers, as set forth.

7. The lubricating devicejvfor the plungers or followers, the same consisting of grooves g m ado in the plun gers orfollowers, and provided with strips of cloth or other absorbent material, substantially as described.
