WILLIAM 'E TALLOOT, OF CROTON LANDING, NEW YORK, ASSIGNOB OF ONE-HALF TO HENRY H. UNDERHILL, OF SAME PLAGE.

BRICK-MACHINE.

SPECIFICATION forming part of Letters Patent No. 237,636, dated February 8, 1881.

Application filed June 14, 1880.

To all lwhom it may concern:

Beit known that I, WILLIAM E. TALLcoT, of Groton Landing, in the county of Westchester and State of New York, have invented anew and Improved Brick-Machine, of which' the following` is a specification.

The object of this invention is to increase the capacity, durability, and efciency of a brick-machine.

The invention consists of a brick-machine provided with devices for preventing rupture of any of the parts of the machine by reason of stones or other obstacles becomingjammed in or about the press-box 5 of a device for preventing the escape of clay about thejoints of the packer or plunger, and of other novel devices, all of which are hereinafter described.

Figure lis a side elevation of the machine. Fig. 2 is a front elevation of the same. Fig.3 is a vertical sectional side elevation of the same on line xx, Figs.2 and 4. Fig. 4 is a plan of the machine. Fig. 5 is across-section of the same on liney y, Fig. 3. Fig. 6 is a front vertical section on line z z, Fig. 3. Fig. 7 is a front elevation of the clod-cutter. Fig. 8 is a plan of the mouth-piece.

Similar letters of reference indicate corresponding parts.

In the drawings, A represents the base or frame for supporting the mill-cylinder and machinery of the device, the legs A' A' being separated by arches A" A", and the said baseAbeing strengthened by the arched ribs or anges A, that project over the arches A and down the legs A' to the feet A"" of the said base A.

B is the mill-cylinder, secured on the base or frame A by means of bolts t a, that pass through the several lugs b b' of the cylinder B and base A respectively. The said cylinder B is composed of two semi-cylindrical sections, B' B', bolted together through their iianges c c, and in the rear of said cylinder B is a door, B", whereby entrance may be had to the said cylinder B for the purpose of cleaning or repairing it.

Secured to the upper and rear edge of the cylinder B is a platform, B', to facilitate the introduction ofthe brick material into the said cylinder B.

B"" B"" are side brackets formed upon the (No model.)

.v cylinder B, near its top; and O C are upright standards or pillow-blocks, rmly secured upon said brackets B"" by the bolts d d.

J ournaled in the bones C' C' that are fixed on the faces of the pillow-blocks C O is the shaft F' is stepped in an open thimble,f',which rests in a central openingin the base or frame A. Through this shaft F', within the cylinder B, the arms F" are passed transversely, so as to extend in equal lengths on opposite faces of said shaft F', from the top nearly to the bottom of the cylinder B, and so as to form on said opposite faces of the said shaft F' a quarter turn or spiralhas shown in Figs. 3 and 4, Within the cylinder B the shaft F' is enlarged, in order to occupy more of the dead" space, or space of least motion,within said cylinder B. Within the cylinder B the lower part of this shaft F' is .provided on opposite faces with lateral lugsff, through which pass the vertical bolts f'f', on which are pivoted the curved sweeps or wipers G G, which revolve with the shaft F' and press into the press-box the clay or brick material that has been tempered by the action of the arms F", each wiper or sweep being secured independently of the other to the said shaft F' for convenience and economy of removal and repair. 0n the concave faces of these sweeps G G are attached the stops g g, that bear against the shaft F' and support said sweeps G G against pressure ofthe clay. Said stops g g may be made parts of the sweeps G G, or may be made separately therefrom,

and they may, if desired, be so arranged as to yield and permit the sweeps G G to yield to excessive pressure within a ruptnring strain.

G' G' represent bars, preferably of rectan gular cross-section, that are passed horizontally and on different planes through the sides of IOO the cylinder B and fixed rigidlyin place to cooperate with the arms F" in tempering the brick material.

G represents the peripheral openingin the cylinder B, and near the bottom thereof, through which the tempered clay is pushed by the sweeps G into the press-box H through the openings h in the back of said box H.

Hl H are side flanges that are lnade parts of the cylinder B, and extend forward on either side of the peripheral opening G, the front edges of said anges H H being vertically channeled, as shown at k, to receive the back plate, H", of the press-box H, which back plate, H, as it becomes worn by the friction of the clay on the front, can be readily removed and a new one substituted for it.

HH are the side plates of the press-box H, held to the flanges H H and over the edges of the plate H by the bolts l; and H is the front plate, provided with slots Z on its edges, and held in position by bolts l that are pivoted on the lugs Z on the outer faces of said side plates, Hf, and are secured by nuts in the said slots Z.

In the bottom of the press-box H is the clodcutter I, consisting of a rectangular frame provided with transverse triangular bars m, with apices uppermost, set at a suitable distance apart for the clay to be pressed between them into the mold M, whichis provided with transverse partitions m', thatform the brick-molds, and are adjusted centrally beneath said triangular bars m, so that, the width of the bars ml being greater than the width of the partitions m of the mold M, the clay will be delivered and pressed into said mold M without rubbing the sand from the sides of said partitions m as it enters the molds. The said mold M is also wider than the clod-cutter I, to prevent the sand with which the said molds are dusted from being rubbed from the l'ends of said molds as the clay is pressed into them.

I is a crenated plate forming the front of the clod-cut-ter I, the teeth t of said plate I resting against the ends of the triangular bars m, while the spaces t" are opposite the spaces between the bars m.

L is the mouth-piece of the said clod-cutter I, extending across the front thereof and provided with rearwardprojecting side lugs, L', the end of one of which rests in the catch of the spring L, that is fastened vertically upon a iiange, Hf, and has its forward pressure regulated by the adjusting-screw L, which passes through alug, l,on said flange H', and which spring Lll holds the said mouth-piece L closed, and said mouthpiece L is pivoted on the bolt-s Ll that enter the ends of the front of the clod-cutter I, and said mouth-piece L is provided with a handle, L, by means of which it is closed down after having been forced open against the pressure of the spring L by a stone or other obstacle that may accidentally become mixed with the contents of the cyl-v Y inder B and have been pressed down in the press-box H. Thus by means of this movable and adjustable mouth-piece L, which yields and opens under the excessive pressure of a stone or other obstacle, the danger of a rupture of any part of the press-box H is avoided; but provided a large stone or obstruction, which, on account of its size, will not pass through the openings t' of the clod-cutter I, becomes jammed between the mold M and clodcutter I during the forward movement of the said mold M, then the point of the breaking rod R' will break off, allowing the hook R t0 swing free and stop the motion of thearms S. The inner face of the said lnoutlrpiece L is provided with projecting blocks m, that enter the spaces t" of the front plate, I', of the clod-cutter I, and overlap the front ends of the a"molds M.

In ordinary.brick-machines the blocks m, for closing the front of the clod-cutter, are each pivoted independently of the other, and each is operated by a separate spring; but such arrangement is objectionable on account of complication of parts and extreme liability of displacement, while in the case of the mouthpiece L all the blocks m are attached to one plate, and all are operated by one spring.

N is the presser or plunger, consisting of an angle-plate fitted within the press-box H, and provided at its ends and face with packingstripsn, that are pressed outward by the screws a to prevent the escape of clay from the said press-box H at the joints between the said box H and the said presser or plunger N. The standard N of said presser N extends upward between the guides N that are bolted or otherwise secured to the front of the cylinder B, the projecting and inclined elbow of said standard N being provided with a vertical slot, n, that extends through it from side to side, and the front of the said elbow being provided with perforations a, for the reception of the pin am', by means of which the length or throw of the pitman O is regulated, and thereby the pressure ofthe presser N upon the clay in the press-box H. Said pin w is preferably madel of cast-iron, so that if the presser N becomes jammed in the press-boxH said pin am will break and prevent injury to other parts by stopping the motion of the presser N, the said pitman 0 being made to straddle said standard N', while the pitmanpin O passes through the slot n and rests on the pin am. The upper end of the pitman O is movably connected with the arm or crank P by means of the crank-pin P', the other end of said arm or crank P being secured on the end of the horizontal shaft P, that is journaled in the boxes P, which are fastened to the front of the cylinder B. The arm P connects the outer end of this shaft 1? with a crank-pin, Pm, on an arm of the cog-wheel D" on the shaft D, which shaft D is above and parallel with the shaft P, and by means of which motion is given to said shaft P" and its connections.

4On the opposite side of the device, pivoted on astud, Q, which projects horizont-ally from a standard or pillow-block, C, is an elbow crank or arm, Q', whose round upper extremity, provided with a roller, o, is within reach of the eccentric D', and whose lower extremity connects with the upper end of the diagonal rod Q", whose lower end adjustably connects, for the purpose of regulating the forward movement of the mold-driving'arms S S, by means of nuts o', with the yoke or link Q'", that straddles and is connected with the rear and free end of the hooked arm R, whose front end is pivoted to the upward-projecting ears of the lever R', which lever It' is secured on the shaft R", that extends from side to side of the base A, near the bottom thereof. Said lever R' extends rearward from the shaft R", and has on its end aperforated lug,p, that is provided with vertical ears p', to hold the hooked arm R in position, and with a lever-screw, p". Through this lug p is passed, from the front, a'breaking rod, :Et/",.of cast-iron or other suitable material, which rod R'" has its rear end extending an inch, or thereabout, beyond said lng 1J, and engaged in the hooked end of the hooked arm R, the said rod R'" being held in place by the lever-screw 19"; hence it will be seen that the lever It' and its connections is moved by power transmitted through the rod Q", link Q", hooked arm R, and breaking rod It'", and that when the strain upon the projecting end of the breaking rod R'" breaks said rod R'" the hook R will swing freely and the lever R' and its connections cease to move.

On either end of the rocking shaft R" are keyed the vertical arms S, that project upward on either side of the base A, and support between them the pushing-bar S', whose ends are fixed in rectangular boxes n which boxes rest in the rectangularly-slotted heads of the said arms S, and said bar S' is adjustable forward or back by means of the set-screws r', that are entered through the heads of the arms S. This bar S' is designed to be adjustable parallel with the elod-cutter I, for pushing the mold M beneath the said elod-cutter I.

T represents a platform or table secured to the base A, and extendingin front thereof, be-

neath and beyond the press-box H, for the purpose of supporting the molds M.

J ournaled in the boxes T', which are verti- 4 cally adjustable by means of the. set-screws s s, are the rollers T", which are set immediately beneath the press-boxH and support the molds M, the faces of said rollers T" being on a level with the face of the barred table T'", that is also fixed on said platform T in front of said rollers T".

wheels E", D", arm I"", shaft P",and crank P to the pitman O, the said parts moving in the directions indicated by their respective arrows, whereby at each revolution the presser or plunger N is forced down on the brick material in the press-box H, to press said material through the clodcutter I into the molds M, that are set on the rollers T". At the same time, also, the motion is transmitted through the eccentric D' to the elbow-crank Q', diagonal rod Q", hooked arm R., breaking bar R'", and lever R' to the arms S, to cause the pushing-bar S' to move forward and push beneath the elod-cutter I, a mold, M, being successively placed by the operator on the rolls T", to be lled from the said elod-cutter I, and being successively pushed forward by the bar S', to be removed as fast as'they are lled.

Having thusfully described my invention, I claim as new and desire to secure by Letters Patent- 1. A brick -machine constructed substantially as herein shown and described, consisting of base A, cylinder B, provided with cross-bars G", vertical shaft F', provided with arms F", and pivoted sweeps Gr, provided with stops g, press-box H, provided with presser or plunger N, having packing-strips a, and a perforated standard, N', provided with breaking 95 pin um', elod cutter I, provided with springregulated mouth-piece L, adjustable rod Q" and its connected hooked arm R, lever R', and adjustable breaking-bar R'", arms S, and bar S', adjustable by set-screws r', and the operating mechanism thereof, as set forth.
