IMPRovED BRICK-MACHINE.

To all whom tt ma/y concern v Be it known that I, GEORGE W. MOOANN, of Springeld, in the county of Clark, and State of Ohio, have invented certain new and useful Improvements in Brick- Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, and to the letters of reference marked thereon, like letters indicating like parts wherever they occur.

'Io enable others skilled inthe art to construct and use my invention, I will proceed to describe it.

My invention relates to brick-machines of the class used for moulding wet brick; and consists in the novel construction and arrangement of a nishing-plate for giving a smooth and even surface to the top ofthe brick, an adjustable mechanical contrivance for securing any desired bottom pressure, and certain improvements in the construction of the follower in the moulds, by which the eficiency of its operation is greatly increased. y

In the drawings- Figure 1 is a vertical section, through the centre of the mould-wheel;

Figure 2 is a top plan view of the device' fo'r securing the bottom pressure;

Figure 3 is a vertical section, on the line y-y of iig. 2;

Figure 4 is a longitudinal vertical section of the follower, on the line z-z of fig. 5;

Figure 5 is an end view of the follower;

Figure 6 is a top view of the follower; and

Figure 7 is a top plan viewof the finisher.

In constructing my machine, I make .a frame, C, and mount therein the pug-mill B, with the shaft H, hav- Ving arms attached for mixing the clay, and also driving-wheel I, and gear-wheel J.

In the same frame, I also mount the mould-wheel A, with its shaft iK, so as to revolve, in part, under the pug-mill B.

The shaft K has a gear-wheel,L, attached to it,.and is driven by the gear-wheel J, all as shown in g. 1.

The mould-wheel A is provided, near its periphery', with a series of vertical moulds, extending through it, arranged so as to come successively under an opening in the bottom of the pug-mill, and be filled with the prepared clay.

VIn each of the moulds, I suspend a followerD, of peculia r construction, by means of a bolt, e, which passes into the periphery of the wheel, and through slots in the follower, as shown in fig. 1.

I construct this follower yD of the proper size to ll the mould, and move vertically in an easy manner therein. It is made with a vacant space in its interior, as shown in g. 4, and has its ends slotted, as

shown in iig. 5.'

Within it, and to its lower side, I firmly attach a curved spring, f, the ends of which extend to and move vertically in the slotted ends, as shown in fig. 4, so that, when thefollower rises in the mould, the bolt e will press against them, for a purpose hereinafter explained.

In the upper ends of the slotted ends, I'place sete screws g, which can be adjusted so as to limit the vertical movement of the follower in the mould, as desired. i

On the top of the follower I place a removable top piece, M, which has sewed to its upper apd lower sides a piece of heavy felt cloth, h, as shown in iig.' 4, by means of strong thread passing through the holes, shown in iig. 6.

The upper side ofthe main body of the follower I make a little hollowing, so as to contain a small quantity of il, which saturates the cloth on the lower side of the top pieceM.

The object of this is to keep the moulds oiled, and thus prevent the follower' from sticking in them, as it is obvious that whenever a pressure is brought to bear on the mould, the oil will be forced to the'edge of the cloth,` and in this way be brought in contact with the walls of the mould.

Near the bottom of the pug-mill B, and to its side, so as to be immediately over the moulds, as they come from under it, I attach a rigid arm, N, and to this arm connect a finishing-plate, E, by means of a screw, a, as shown in iig. 1. i

This nishing-plate I make substantially in the form. shown in g. 7. Its lower surface is smooth and level,

while its upper side is provided with a groove, extend-` ing across it, as shown in the same ligure, and has inserted in it a wooden block, t, as shown in figs. 1 and 7. The screw a, which connects the nishing-plate E to the arm N, does so by entering the block t.

Inthe arm N, I also place set-screws j, so that, by means of them, the finishing-plate E may be adjusted,

and held as rmly to the uppersurface of the mouldwheel as desired.

The obj ect of connecting the nishing-plate E to the arm N, by means of the screw a and wooden block t, is to allow the plate to be carried away, in the event of its coming in contact with stone or any foreign substance that may have got into the mould, and thus protect the machine from any serious injury that might otherwise happen.

`In order to secure any desired bottom pressure to the brick,I connect to the shaft K, so as to turn easily about it, and to rest on the licor of the frame supporting the,inclines for giving motion to'the followers, a flat arm, F, long enough to project beyond the periphery of the mould-wheel, as shown in fig. 1, and shaped as shown in fig; 2.

It is provided with an annular opening, k, through which the shaft K passes, and a slot, l, through which passes a set-screw, el.

On the upper side of this arm, I place an adjustable wedge, Gr, also provided with a slot, m, through which the set-screw dvalso passes.

vThe thin end of this wedge passes under an incline, cfwhich moves upon and is held in place by pins, n, attached to the arm F, as clearly shown in hg. 3.

When the set-screw d is loose, the arm F can be moved laterally a distance equal to the length of the slot l, and the wedge G, in like manner, a distance equal to the length of the'slot fm.

' The incline c is arranged so that the followerD must pass over it, and, as by these simple devices the incline can be readily adjusted, it is obvious that any desired bottom pressure can be given to the brick when or as it passes under the finishing-plate.

In operating my machine, the power is applied in the usual way. The mould-table carries the moulds successively under the pug-mill, where they are filled; the inishingplate E Vmakes the upper surface of the brick even and smooth; the follower, as it passes up and over the adjusted incline, gives the brick the desired bottom pressure.

ter'this is dona/the follower, as the/table con'-V tinues its rotation, is carried up by another incline, not shown, and raises the brick to the surface of the table, from which it is easily removed.

When the follower is thus carried up by the incline, the springj` comes in contact with the bolt g, and is forced back, but, as it passes over the incline, its recoil carries the follower down. leaving the mould ready to be filled again.

The cloth on the upper side of the mould not only gives a clean nish Ito the brick, but prevents it from sticking to the follower, while the intervening cloth serves partly as a cushion, as well as to keep the mould oiled.

By setting the screws g, the position of the follower can be so changed in the moulds as to make the brick of any desired thickness, as the heads of these' screws rest upon the bolt e, which suspends the follower.

AHaving thus described my invention,

1. The nishing-plate E, provided with a wooden block, fi, constructed and arranged to operate substantially as herein described, and for the purposes set forth.

2. The follower D, with its removable top M, covered on both sides with cloth h, and provided with the spring fand set-screws g, constructed andarranged to operate substantially as herein described.

W 3.VY The Yswinging armY Ein combinationwiththe adjustable wedge G and incline c, constructed and arranged-to operate substantially as herein described.

4. The follower D, constructed as herein described, in combination with they bolt c, fixed transversely in lthe mould, and passing through the follower, for .the purpose set forth.

The spring f, in combination with the bolt c, for returning the follower to its position, after delivering the brick, constructed and arranged to operate substantially as described.

6. The set-screws g, in combination with the bolt e, xed transversely in the mould-wheel, for determining the thickness of `the brick, substantially as described. GEO. W. M CCANN.
