UNITED STATES PATENT OFFICEc i IMPROVEMENT IN BRICK-MACHINES.

Specification forming part of Lett( rs Patent No. 153,189, dated July 21, 1874; application il'el June 26, 1874.

To all whom it may concern:

Be it known that I, GUsTAv BoUDRIoT, of IVehringhausen, Germany, have invented a new and Improved Brick-Machine, of which the following is a specification:

The nature of my invention consists in the arrangement of a machine to manufacture bricks. upon the principle and after themethod of hand-working; and it consists, first, in the arrangement of pressing the bricks by means ot' rollers 5 secondly, in the arrangement of a bottomless mold or form chain, thirdly, in the arrangement of sprinkling the bricks, from above and from below, with dry warm sand 5 fourthly, in the peculiar mechanism for pushing the bricks out of the molds or forms, and transporting the same away. v

In the accompanying drawings, Figure I represents a longitudinal section of a brickmachine embodying my invention. Fig. II is a cross-section at line 2, Fig. I. Fig. III is a top view of Fig. II, of the pressing-out mechanism. Fig. IV is a cross-section at the line 3, Fig. I. Fig. V is a horizontal half-section at line 4, Fig. I.v Fig. VI is a horizontal halfsection at line 5, Fig. I.

Similar letters represent correspon din g parts in all the figures.

On a suit-able frame, A, two drums, B B', are supported, over which an endless mold or it'orm chain, C, is stretched. Above the drum B the clay-mill I) is arranged. The upper part, D,ot' the inside of this clay-mill,is made funnel-shaped to receive the clay, which may be brought into the same by means of suitable conveyers. The central part, D, of the clay-mill is made octagonal, while the lower part, D" ,is square, and as large 'as the framing will allow, for the deposition of the stones and other pernicious substances. This lower part D is closed by doors E E, (see Figs. I and VI,) to remove the stones and other substances out of the mill. The claycutter consists of an upright shaft, F, running in suitable bearings, and has attached to it two rakeknives, Gr G, passing by a grate, H, situated in the upper part of the square part D, for the purpose of separating the stones and other substances from the clay. K are a number of driving-knives, securely fastened to the shaft F at angle of about thirty degrees, to which smaller knives a arefastened. These knives will thoroughly mix and cut up the clay while passing throughthe octagonal partD. The grateH consists of bars b, which are bent in the radius of the mill-spindle, resting on suitable bearings. (See Fig. VI.) One part of this grate H is left open for the stones and other substances to fall oft' into the square bottom part D. The bars are made conical, to prevent them being stopped up with stones. The rake-knives Gr are provided with points c which pass between the radial bars b of the grate, and whereby the clay is cut up fine and forced through the grate H, while stones, &c., are pushed away till they fall through the open part H ot' the grate. Under the grate an inclined surface or funnel, L, is arran ged, whereby the clay is conducted downward upon the mold or form chain C. This mold or form chain (l consists of tive, more or less, brickforms cast together, and a number of them jointed together to form an endless chain. These molds are bottomless, consisting only of side walls with projecting flanges on the outer sides and at front and back. The projecting flanges c on front and back, or forward and behind, touch each other (see Figs. I and III) where the chain forms a straight line, to prevent any clay falling between the same. The proj ecting ian ges d at the sides (see Figs. II and III) are made with recesses g, for the purpose hereafter mentioned. M is a plate attached to the frame A, just below the upper part of the mold-chain G, and below the funnel L, forming a bottom for the clay which it presses into the molds; and to support the mold-chain (l in a straight line. Forward of the plate M. two rollers, N N, are tixed in suitable bearings on the frame A, one above and one below the mold-chain C, through which the clay is pressed into the molds. Two smaller rollers, I? I), likewise situated above and below the mold-chain C, are arranged forward ot' and close to the rollers N, and bear hard upon the top and against the bottom of the molds, through which the clay is pressed firml y into the molds, and any surplus clay at the top and bottom of the molds re moved.

AThe forward drum, B, receives a regular motion, and gives thereby a con tinuous motion 2 maniac tothe mold-chain C. The lower part of the chain C passes through a suitable tank, 0, filled with water, whereby the molds are always washed and cleaned before the same pass between the funnel-plate L and the bottom plate M. The lower roller N runs likewise in a tank, Q, containing water, and a stream of water is directed upon the upper roller N. Anysurplus water is pressed out by the smaller pressure-rollers l l. Near the middle of the machine, forward of the pressure-rollers N and l, t-he sami-sprinkling mechanism is arranged. The same consists of an inner box, R, surrounded by an outer shell, S. In the central part an opening, T, closed on the sides, is arranged, through which the upper part of the moldcl1ain C, with the mold filled with clay, passes. To the top of the inner box a funnel,U, is fitted, to ull the same with sand. In the bottom of this inner sand-box It a roller, l1, (see Figs. I and 1V,) having rightand-left-handed wings on its circumference, arranged, to keep the sand in motion and move the same toward the middle of the box. ln the top and bottom of the central opening T, elongated holes of a length `equal to the width of the mold-chain C are made, and close to these holes fan-wheels f f are arranged in the inside of the sand-box 1t, to keep the sand in motion, and the lower -wheel being particularly for the purpose of throwing the sand upward against the under side of the clay previ.- ously pressed into .themolds of the chain C. To the upper hole a slide, i, is fitted, to regulate the quantity `of sand to be thrown upon the upperside of the mold-chain U, upon the top of the clay which has been pressed into the said molds. The hole in the bottom of the opening T does not require any slide to regulate the amount of sand, as any excess will fall back into the sand-box It. The space between the sand-box It and the outer casing S is supplied with steam through the piped', (see Fig. lV,) while the pipe l, at the bottoni, carries oiig the condensed water. the sand in the box R will always be kept warm, and heated sand will be sprinkled upon the top and against the under side ofthe clay in the mold-chain. C, which will, at the same time, more readily absorb any excess of water in the clay.

After that part of the mold-chain C which has been filled with clay has passed through the sand-box, and has been sprinkled with warm. sand, as above described, the further motion of the mold-chainC brings those molds filled and sprinkled under the pressing-out Inechanism. (See Figs. I, Il, and III.) same consists of plates 01 pl ungers V, attached to a cross-bar, Vv", provided with rollers m m on its ends, guide-rods 'nl n projecting upward, and arms p p projecting downward, in a line with the guide-rods n n. The guide-rods a a move in guides q, attached to guide-rods or frames X, moving or slidiiig freely horizontally, in suitable bearings fui, fast to the frame A. The rollers m fm, on the ends ofthe cross- ]ly this arrangement,l

The

bar iV, are fitted and move in and upon frames Y, attached to the inside ot the framing A. These frames Y are provided with V-shaped grooves S, open at the top. The downwardprojecting arms p p rest upon the projecting side flanges d of the mold-chain (l. (See Figs. II and III.) The number of the plungers V corresponds with the number of molds in each link of t-he mold-chain C, and are made double, so `as to it into the molds of two links at the same time and operation, and, as shown in the drawing, consist consequently of ten plnn gers attached to the frame or cross-bar NV.

The operation of thispressingout mechanism is as follows: Vheu the mold-chain comes directly under the plun gers V, the recesses or notches g in the projecting side flanges d are directly under the arms p j), which, having previously rested upon the iiangeSl d, fall into these recesses or notches g y, and bring` the rollers m. in, on the ends of the cross-bar into the V-shaped grooves S in the frames Y. The further progress of the chain (l will cause the plungers V, with their cross-frame lV, to move with it, causing the plungers to move at the same time downward, so as to press the clay which had been iilled into the forms or molds out of the same, and then to move upward again out of the forms or molds, in consequence of the ends of the cross-fra-meV being forced through the V-shaped recesses .s' in the frames Y during the forward motion of the mold-chain G, and the plungers V, and crossbar KV.

During this forward, downward, and up ward motion ofthe pl'un gers V these plungers are caused to :move perpendicular, downward and upward, on account of their arms p p being held fast and guided in the recesses f/ y in the side ianges d of the moldchain (l, and their guide-rods n u being guided in the guides q (l on the frames X, which latter are, during this operation, caused to slide horizontally in their fixed bearings w. In the end of the frames X levers Z are arranged, turning in suitable bea-rings r, fast to the framing A, and operated at their lower ends by projections a', fast on the side surfaces of the chain-drum l.

As soon as the plungers V have moved out of the forms in the mold-chain C, as above described, the projections .t 011 the drum 'i3 will act against the lower ends of the levers Z, causing thereby their upper ends to act upon the frames X so as to move the same, and consequently the cross frame or bar V, together with the plungers V attached,backward again into their original position, ready for the next operation, the rollers m m passing during this operation over the curved surfaces i', between the openings of the V-shaped recesses s on the frames Y, to support the cross-frame W and plungers V. Below the pressingout mechan ism,between the upper and lower part of the 1n old-chain C, rails u are attached tothe f raming A at right angle to the chain G, upon which suitable carriages l are placed to receive the brick s or molded clay as soon as the same are pressed out one or more teeth, as to cause the carriage It to stop during the time thevpressed clay or bricks are delivered out of the molds by the above-mentioned mechanism, and deposited upon said carriage.

Instead ot' heating the sand in the box R by introducing steam into the space between sa-id box R and the outer casing S, a grate for irc may be arranged in the lower part of the outer box or casing S, and the sand heated by the circulation of the iiame and gases around the sand-box It.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The endless mold chain C, formed of links, each link consisting of a number of bottomless molds or forms cast together and provided with projecting end flanges e and side iianges d, in the manner substantially as set forth.

2. In combination with the bottomless moldchain C, the fixed plate M below said chain, and the presser-rollers N N and P P, situated above and below the mold-chain C, constructed and arranged in relation with the clay-mill, substantially in the manner and for the purpose specified.

3. The sand-box R, provided with rollers or fan-wheels h and ff, and central opening T,

through which the mold-chain G passes, in combination with a surrounding casing, S, supplied with steam or heat, the whole being constructed' and arranged in the manner and for the purpose substantially as set forth.

4. The plungers V, attached to a cross bar or frame, WV, and provided with arms p and guide-rods a, in combination with frames Y provided with V-shaped grooves s and trames X, moving horizontally in suitable bearings 1v, the whole being constructed, arranged, and operating together in the vmanner and for the purpose substantially as described and set forth.

- 5. In combination with the frames X, the levers Z, turning in suitable bearings c attached to theframe A, and acted upon by projections :v fast on the sides of the .chain-drum B, substantially in the manner and for the purpose set forth.

6. In combination with a mold-chain, C, and the pressing out mechanism, arranged and constructed as above described, a carriage, R, running at right angle with said mold-chain C upon suitable rails a, attached to the framing A, arranged and constructed substantially in the manner and for the purpose specified.

In testimony that I claim the foregoing I have hereunto set my hand.
