JOHN C. -MILLER, OF BUSHNILL, ILLINIS.

Letters Patent No. 81,928, dated September 8, 1868.

IMPRUVED BRICK-MACHINE.

TO ALITWHOM IT MAY CONCERN: y

Be it known that I, JOHN C. MILLER, of Bushnell, in the county of McDonough, and State of Illinois, 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, and to the letters of reference marked thereon, which form a part of this specification, in which- Figure 1 is a plan yview of the base or'bed of the machine, and

Figure 2 is a side section, of reduced dimensions.

The nature of my invention consists in the construction and general arrangement of a machine for making brick, which is simple and cheap, as well as durable.

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

A represents the bedjor base, which is made of any dimensions required, and rests on beams B B, as Vshown in iig. 1. On each side of this bed is a groove or way, c, the width ofthe brick-moulds D D, which slide therein.

Over the centre of the bed A, a tub, E, is placed, in such a manner that the centre thereof is just over the centre of the middle beam, B, and its sides extend over the ways c c. The bottom of said tub is open at the sides where it is over these ways.

Alframe is made in any suitable manner on the sides of the tub E, which frame has a cross-bar, F, above the top of the same. From this cross-bar a shaft, G, descends through the centre of the bottom of the tub E, and-rests in a recess in the middle-beam, under the frame A.

Onthisvshaft, between the tub and the frame, a cogged wheel, H, is secured, which wheel worksinto similarly cogged wheels, I I, one von each side of the former.

Theselatter wheels are so arranged that the cogs on o ne extend a trifle into the way C, on one side, and the cogs on the other' wheel into that on the other side, the slats forming the inner sides of theseways being cut open for that purpose.

The wheels I I a're provided with journals, so that-` they work on the upper side of the frame, and partly under the tub. i

The moulds D D are made in any of the known and usual ways, but provided on one side with a ratch-bar,' a, so that when inserted into the ways c c, the wheels I I will catch them and carry them forward under the tub.

. It will beseen from the position o f the wheels I I, that they work in opposite directions, so that one person will stand at each end, and on one side pass in the empty moulds, and on the other receive the full ones.

Theinside of the tub 'E is provided with a. number of bars secured to its sides, and on the shaft G is also a number of such, as well as several bevelled arms, as shown in iig. 2, which serve to work the mud in the tub. These arms and bars, as well as the shaft G, are to be made of wrought or cast iron, or other suitable material.

Instead of having a tub partly open at the bottom, as above described, a platform may be laid over the bed A and ways c c, on which the tub, without bottom, will rest, the platform in that case being out open to correspond with that part of the tub which is over the Ways.

At theend of the ways c c are strips of, rubber b 6, which serve to clean the mould of any sand or dirt adhering to its outside when entering the machine, and in the grooves or ways directly under the opening for the mud, are springs, which serve to hold the mould tightly, and prevent the mould from getting into the groove and on the cogs, and also to cut the mud smoothly from the mould, making the,top of the brick smooth.

Before filling the tub, put one mould in each groove, and turn the shaft Gby means of horse-power attached to a lever, which is secured to said shaft until the mould passes beyond its cog-wheel, where it will remain, stopping the mud from passing into the groove. The tub is then filled, and when the mud is suiciently tempered, place the empty moulds in the groove, which will shove the full ones out. Then keep the tub filled, and it will temper the mud su'iciently to keep the machine running.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

The tub E and shaft G, in combination with the frame A, ways e c, cog-wheelsH and I I, and moulds D D, all constructed as describedand.operating substantially as and for the purposes herein set forth. i

In testimony that I claim the foregoing as my own, I aiiix my signature in presence of two witnesses.

I JOHN C. MILLER,
