IIMPROV-ED BRICK-MACHINE Thoehedule referred to in these Lettore-Patent nndmaking part of tho um.

Be it known that we, JOHN Bnn'r'z, WILLLAM SANG- srnn, and JOHN F. BRETZ, of Springfield, Sangamon county, State of Illinois, have invented-a new and imv proved Brick-Machine; and we do hereby declare that side taken out, to show'the inner arrangement.

A is the mixing-box, supported upon an open framework, to leave .the spaceI clear underneath, so that moulds can be inserted under the press fromv either side.

Bis a shaft, of castliron or wood, and turned by the sweep C, said sweep turning towards the left.

D D-arel knives, perforating the shaft B, and revolving with it, between the cross-bars E E, to cut and grind the clay or mud. v

E E represent any number of cross-bars, running from side to side of the mixer A, and close enough V together to hold the lumps until the knives D catch Aand .crush them.

- l@ is the press, at the bottom ofthe shaft,for press-5 ing theclay into the -moulds.A

G and 'H' comprise the apparatus'whichraises and lowers the shaft and press during the revolution of' the sweep (l, and consists of the, two 'iron half plates G, cast upon the shaft, inclining' across each other, soy that the opposite ends of each 'shall have 'the same depression o1' elevation, andthe two nprights H H, over which the-two halt' plates Gr` pass, Athus raising the shaft and press from oli' the mould' when the plates 4Gr pass over the uprights, and dropping down by their own weight when these plates have passed over the uprights.

` I I are'two pins upon the sweep, exteudingdownwards from the same, at equidistance from the shaft, and arranged to catch the rod f of the lever K, during the revolution of the sweep O, and lthus work the lever K.

K is the lever, which consists of the Iiron rod j, running quite over the clayor mixing-box A, and down.

on each side, and lthe round connecting-bar L, and stick M, the whole working upon the pivot a, which4 fastens it to the left side of the-mixer A.

1 That part of the iron rod which passes over the top of the mixer is shapedso thattlie pins I catch the portion nearest, and shove it back, and slide OH' from it, after it-moves along half way, and the lspring N pushes the lever back, so that the nent pin catches it inthe same way.

AM is a square stick,attaehed, by loose sliding rings,

tothe connecting-bar-L, so that it always keeps its.

horizontal positionwhen the lever is moved forward,

4and by this the moulds are pushed under the press.

, N is a spring, which pushes the "lever back to its place when' thepressurefrom the pinsabove isremoved. v

O is an adjustable carriage, to runv the moulds 'out upon, and is supported by four screwflegs, at-each lower corner of the machine.v

In other brick-machines, these carriages are fastened tightly to the sides, and, when worn at the bottom, they drop from their proper place and level, and have to be takenout for repairs.

' When this. adjustable carriage 0 is thus worn or drops out of place, we raise it in place by simply turning the screw-legs upon which itrests. X isa movable side, which can be taken out when the machine is to be cleaned, and Q Q are two' slats,

and R R, two cast-iron ears, and S, an iron slat, all

of which, combined, form the fastening for the movable side, X.' A

The moulds used are like other moulds with' sliding partitions, with the exception of the cross-bars'u u,`

Figure 4, which are riveted in the moulds, to give them additional.strength. l V are rollers, in the "adjustable carriage O, upon which the moulds rest when being filled, and by which the sliding them off upon the carriage is facilitated. Figure 6 represents drying and dumping-forms connected with this machine. The bricks aredumped from the moulds upon one of these forms, and then another form is placed directly over it, andthe next mould dumped upon-that, and so on, one over the other, the whole only occupying a-'small space, and putting the bricks in a condition for drying, as well as being -sheltered from rain.

What we claim as our invention, and desire to se-v The arrangement and combination ofthesweep C and pins I L'with the lever K, (said lever being constructed as described,) with the twisted iron rod'f, connecting-bar L, stick M, and pivot a,A and spring N, all

operated as and for the purposes hereinset forth.
