'TO ALL liv-HOM IT MAY CONGERN:

IBe it known that we, WILLIAM CnIGnToN and HENRY Bohemia', of Fort Wayne, in the county of Allen, and State of Indiana, have invented certain .new and useful Improremcnts in Brick-Machines; and we do hereby declare that the following'is a full, clear, and exactv 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

Figure 1 is a side elevation.

Figure 2' is a 'plan o'f the rockingshafts, and the parts attached thereto. Figure 3 is a. plan ofthe moulding-slide. Figures 4 andr5 are elevations-of the two parts which form the clay-mill; and Figure G is a view of one of the rolling-plungers. vTo enable others skilled in the art to make and use our invention, we will now describe its construction and operation.

Arepreseuts the framework of our machine, and e d table or platform supported by mea-'ns of nprights or bolts@ a. This table is provided-at its centre with an opening aboutthe size and shape of arblick, (represented by dotted re'd lines, lig'. 1.) Immediately over this opening is the stationary clay-mill 6, shown also by red lines,

.'fig.V -1. `The interior portion of this .mill is tapering, while its` bottom is provided with a similar opening to that described in the table. B represents vthe adjustable clay-mill which setsover the other, as clearly indicated 'in iig-1., and should.` be made in two equal parts, the edges of which are vturned out, as shown in figs. 4 aud5.

OneofY these parts is provided with slots, and the other with clasps, as seen in the figures alluded to abovei Thus the two maybe readily1 adjusted or taken apart. C represents a horizontal shaft, upon which are the two bevelswheels ff and crauk'g. D -is avertcal hanging shaft provided with stirrers i L and spiral wings'z' z'. Said wings are for the purpose of forcing trhe clay into the moulds. At, the top of the shaft D is the berel-gear wheel K, which is operated by gear-wheel ff Eis also a vertical shaft, with 'bevel-gear Zworkiug in wheel f", as clearlyseen in lig. 1. At the bottom of this shaft is the crank, m, the objectof which w-ill be more fully seen'prcsen'tly. F F represent twovrocking-shafts, upon which are thearrns n` n and lifters O O. The arms 1 n,A are connected by means ofthe rocking-bar Gr.Y pp are two slides on the bar G, which are provided with thumb or set-screws, as seen in fig. 1.l 4-It should be observed that, while the machine is in operation, the slidespp are immovably fixed or secured on the bar. g represents a spring fastened to the under side of the'table e, its ends' resting upon bar Cr.A H is the mould-slide, which is-prvided with the moulds S S.. On the end of thesemoulds are theiproj'ections t t, as partly seen in fig. 1.v 'h'e .slide H slides in grooves on the under side of table e,` and is connected to crank m by means of rod u. P represents one of the .plungersnI Said plungers aremade to t accurately yet easily in the moulds, and to them are attached the grocved rollers m :v by means of the elon gated'l axles y y more fully shown 'in iig.Y 6. These rollers rest and travel upon the rail W, which is provided with two roundingllcvations, as seen in iig. 1, the object of which is to force the plungers upward, and thus press the clay in the moulds. p f i The operation of our machine is as follows i The mill being -supplied with clay, motion is imparted to the machine b'y means ofthe crank, orsuch other'way as maybe preferred. The spiral wings force the clay into themoulds, and, as they are coming from nnderthe table, the elevationson the rail W force the plungers upwards and press the'brick. As soon as the moulds are out from under the table, the projectionson the plungers Strike against the slides on bar G, which operates therocking-shafts. The lifters arerthusthrowu upagainst the elong gated axles and force the plungers upward, which relieves the moulds from the brick which has been'pressed.

What we claim, and desire to secure by Letters Patent, is-` l 1. The rocking-shafts F F, in combination with bar as and'for the purpose described. 2. -The lifters O 0, operating as and for the pnrposeset forth. i 31 The `combination of `rocking-shafts E F fwith lifters O O, bar.G,'a-nd spring g, substantially csset forth. 4. .The plungers P P, provided with rollers a: 1:, rail W, slides 12 rockingshafts FF, and lifters O O, all

combined and arranged as and for the purpose set forth.

In testimony that we claim the .foregoing aS our own, we ax our signatures in presence of two witnesses.

HENRY ROESLER.
