IMPROVBD BRICK MACHINE.

TO ALL WHOM IT MAY CONOERN:

Be itknown'that I., PHILIP H. KELLS, of Adrian, in the county of Lenawee, and State of Michigan, have invented certain new and useful improvementsin Brick Machines; and I do hereby declare the following to he a. full, clear, and 4exact description of the same,'reference being had to the accompanyingdrawings, which are made part ofthis specification, and in which- Figure lis a sectional elevation of a brick machine embodying my invention, the plane of vertical section .being indicated by the linesziz, fig. 2.

Figure 2 is a top view ofthe same partly in section, the planes of horizontalsection being indicated by the lines y y, fig. 1. i v l Figure 3 represents a vertical sectionon the line z z, tig. 2. Y

Similar letters of reference indicate corresponding parts in the two figures.

This invention relates to certain improvements in the brick machine for which Letters Patent, numbered 63,057, werevgranted tome on the nineteenth day of March, 1867.'

One feature of the present improvement consists in the method of constructing the bed-platc for the reception ofthe pug-mills, said plate being of a single piece of metal, which is cast solidly with annular langes, into k which-the lower ends of the cylinders or pug-mills are inserted.

The invention also consists in the arrangement of a stationary plate, which sustains the pressure when the followers are madctc act uponthe clay, and which is formed with a sharp cuttingedge, which occupies aposition on the interior of the pug-mill at the point where theiilled moulds pass fromvbeneath the discharge aperture in the bottom of the said pug-mill, and which serve to shave or remove the superfluous clay from. the mouldsr Vand .leave the same inside ofthe clay-mili or tub.

.The invention-also consists in adjust-.ably supporting the bed-plate, so that from time to time, to compensate for wear on the fctionaiA surface of the mould-wheel and bedplate, it may be moved and set or held in`closer proximity tothe latter' in order to prevent the clay from working out between the joints.

.The invention furtherrconsist-s ina lnovelfmethod 'of arranging and adjusting-the inclins which elevate the followers to compress the `clay in `-the moulds; -constructing and applying a smoothingfknife and clay-guard;

.adjusting the rollers upon whichthe mould-wheel revolves, and arranging the 'gearing by which the mouldwheel is driven, all as will be hereinafter ful-ly explained. p I i In the accompanying drawings, A may represent a suitable base or frame, upon which the several operating parts of the machine are mounted. B is a bed-plate, supported upon the pillars or posts C C, the upper ends of which areprovided with screw-threads and tted to the threaded sockets D D. By the rotation of the posts C the bed-.plate B may be lowered so as to bring it snugly against thel surface of the mould-wheel E, and thus prevent the clay from working out between the joints. j ".lhis adjustment is made from time to time in order to compensate for the wear to which the frictioual surfaces of the bedplate andmould-wheel are subjected. .The adjustment of the hed-plate may be effected by any othersuitable means. The bed-plate B is cast in one piece and is formedsol'idly, and, in conjunction with the annular ilanges B1 B1, which receive the lower ends of thel pug-mills F F, and confine them in position upon the bed-plate B. Stay-rods F1 F1 and nuts are employed to hold the pug-millslrmly in position.V G is a horizontal driving-shaft, which may be driven by a'hand upon the pulley Ghaud which communicates motion to the pug-mill shafts F2 F2 through the gearing GrzG G3 G3. The clay'is agitated and worked to the proper consistency by the arms or blades Fa on the rotary shafts Fil F2, and is ejected through the discharge aperture Hl at the bottom of each pug-mill .F by the spiral wings F4. I I are vertical shafts, rising fromeither end of the hed-plate'B, and rotated by the shaft Gr through'suitable gearing G5 G6. The lower ends of the shafts I I carry gear-wheels l1 Il, which communicate a rotary motion to the mould-wheel E `through the intermediate gear-wheels `Iz I2, which mesh ywith the cogs ou the periphery of mouldwheel E. The frame lin which the driving-shafts have their bearings is erected upon the bed-plate B, and moves with the latter under the adjustment to which it is subject. J-{see fig. 3) represents a plate, which issecure'd to the under side of the bed-plate B in proximity to the aperture Hl, through which the clay is forced from each of the pug-mills F into the'mo'ulds e of the mouldwheel E. Each of these platesJ is formed with a sharp cutting edge, which rests upon the face of thcmould=wheel E, and serves to shave off andwremovei'the superiluous clay from the top of moulds e, as the latter-pass from beneath the aperture H1; most of the superiiuous clay is thus prevented from passing ont of the pug-mills. As soon as a filled mould, e, reaches a point immediately' beneath the plate J, the follower K of that mould is forced upward by the Contact of its roller K1 with the incline' L, the clay being thereby firmly compressed between lthe follower K and plate J. The bar of metal upon which the incline L is 'formed is adjustable vertically by meansof the rods M and nuts m, for the purpose of' adapting the machine to be set from time to time to compensate for the wear which is duo to friction.- It willalso be seen that while the clay is being subjected to the action of the follower K, the rods M serve to hold that part ofthe bed-plate, and thus relieve the supporting frame of undue strain. A knife, N, employed in connection with eachpug-mill to removerany superfluous clay which may project above the moulds e, when the llatter have passed from under the bed-plate. As Jghe filled moulds'emeige from under the bed-plate and pass beneath the knife N, the latter removes whatever superfluous clay there may be at the top of-the moulds, and the clay thus removed is prevented from getting upon that part of the wheel E containing the preceding moulds by the shield-N1, which is a flat piece, secured edgewise to the knife N by means of the threaded rod 71, and nut4 nl at its outer end, and by the projection [12 on the bed-plate at its inner end. The outer end of the knife N is held against horizontal displacement by means of the rod n, while the inner end of the knife abuts against the stud it?, which serves to `properly retain the knife in position wit-hout fastening or attaching it to thev bed-plate. The set-screw n3, together 'with the nut nl, serves to hold the knife N snugly in contact with the face of the mould-wheel E. Both of the longitudinal edges of the'knfe N are ground to an edge, so thatgwhen one side becomes impaired by use,` a new cutting edge may be brought into requisition by simply turning thelznife over. As the mould-wheel continues to revolve, the moulds e are successively carried under the knives N, as above described, and then the rollers K1 move in contact with the stationary inclined planes O, and they bricks are ejected upward from theinoulds. v i

The central support of the mould-wheel E may be similar to that shown in my patent previously alluded to; but in the present case it is represented as having two central bearings, e2 e3, instead of O re'as proposed in the previous patent. The wheels l), which afford bearing points for the wheel E near its outer rim or circumference, are each journalled in a metallieframe, P1, which is fulcrumed or adjustablysupportcd upon the stationary bnse-platePg, lwhich is formed with `vertical projections pp, for the lateral support of the frame P1, as clearly represented in iig. 2. The arm or limb p1 ofthe frame P-, is held by a screw-bolt, p2, and nut p3, by turning which latter the frame P1 may be vibrated after the manner of a lever, so as to force the wheels upward and hold them in proper position to aiord the requisite bearing for the wheel E. The tendency ci' the pugfmill 4shafts, when in operation, is iso force upward the horizontal girt R, which connects the endsof the shaftspporting frames. I therefore propose to employ a stay-rod, Q, which, at its lower end, is tapped inte the hub B* on the bed-plate 13 or otherwise fastened thereto, and fastened at the upper side of said girt Rby means 0f nut B5.

i Having thus described my invention, the following is what I claim as new herein, and des-ire to secure by Letters Patent: I

1. Iclaim the bed-plate B, formed with the annular anges B1 B1, for the reception of the pug-mills F F, substantially as described.
