SPECIFICATION formingpart of Letters Eatent No. 625,781, dated May Application filed February 11, 1899. Serial No. 705:2'79.

To all whom it 77tfby concerns 7 Be it known that I, FRED MA ARTH v, a subject of the Queen of Great Britain, residing at Sayreville, in the county of Middlesex and State of New Jersey, have invented new and useful Improvements in Brick-lilachines, of which the following is a specification.

' Myinvention relates to brick-maehines,and has for one of its objects to provide a machine capable of making in wood molds what is known in the trade as a stiffmud brick with sanded surfaces, as distinguished from the ordinary sanded soft-mud bricks made by machines in present use. The product of my improved machine-2l 6., stilt-mud bricks with sanded surfaces-is suliiciently firm and otherwise adapted when they leave the machine to be immediately built up in hacks for drying, preparatory to being fired in kilns. This is nottriie of softnnud bricks with sanded surfaces, such bricks having to be dried until they are suflicientlyfirm to adapt them to stand in hacks. Such drying of the soft-mud bricks is effected by laying the bricks on their liat surfaces on a floor; bu t this method is objectionable because of the large floor-space re quired and the delay which attends it. Another method of preparing soft-m ud bricks for the kiln has been to place Ihem on pallets, which are mounted in racks, there to remain until the bricks are sufficiently dry for firing. This latter method does not include arranging the bricks in hacks, and is objectionable, because it entails the employment ofa large quantity of lumber, the initial and current costs of which are considerable.

The brie-ks made by my improved machine are, as before stated, adapted to be immediately built in hacks, and therefore it will be appreciated that the said machine contributes very materially to the cheapness of the production of the bricks.

A second object of the invention is to provide a brick-machine embracing molds having square side walls, which insure the formation of square bricks, movable mold-bottoms, and means for actuating the said bottoms at the proper time to positively eject the bricks from the molds.

A third object of the invention is to provide a ln'iclemachine adapted to subject opposite (N0 modem sides of bricks to great pressure and sin1ultaneously make any desired designsuch as a panel, trade-mark, or the like-4n both sides of the fiat bf the bricks.

A fourth Object of the invention is to provide a machin capable of cheaply and expeditiousl y prodiicing what is known to the brick-making and bricklaying trades'as repressed stretchers. 7

Other objects and advantages of the invention will be fully understood from the following description and claims when taken in connection with the annexed drawings, in which-- Figure l is a side elevation ofa machine em," bodying my invention, the same being shown as partly broken away. Fig. 2 is a longitudinal central section of the same. Fig. 3 is a plan view. Fig. -i is an enlarged transverse section taken through one of themold-wheels in the plane ii'idicated by the line 4 4. of Fig. 1 and illustrating certain parts in elevation.

Fig. 5 is a detail longitudinal section taken in a plane at one wheels. Fig. 6 is an enlarged detail trans verse section illustrating the clay-cutting mechanism.

In the said drawings similar letters desig nate corresponding parts in the several views, referring to which i A is a frame of the machine, which may be of any construction suitable to thepnrposes of the invention and maybe placed on ailioer or other base, and B is a longitudinally-dis posed clay-chamber. This chamber has tapered dies or at itsopposite ends and is designed to be charged with suitable mud ore-lay through a conduit b, inwhioh is arranged an agitator c, the purpose of which is to accelerate the passage of clay to the chamber. In the clay-chamber is a reciproeatory follo'wer O, which has for 'its purpose to alternately force the clay in opposite directions through the dies (1, and thereby charge the molds hereinafter described. The follower has one or more openings d, disposed lengthwise of the chamber and connecting the portions of the same at opposite sides of the follower, and hence it will be seen that when there is more than enough clay at one side of the follower to charge the molds presented to one die the side of one of the mold-- will be in ordinary surplus will be forced through the opening (I to the opposite side of the follower, where it is left to be forced through the other die and into the molds presented to it on the return stroke of the follower. The follower is equipped with lateral arms 6, extending through and movable in slots fin the side walls of the clay-chamber, and on the said arms arejournaled antifriction-wheels g, as best shown in Figs. 1 and 3. These wheels 9 are disposed at opposite sides of the chamber B and are each arranged between two camsD, the said cams being of the shape shown in Fig. 1 and being fixed on shafts h. the shafts h are gear-wheels 2', each pair of which is intermcshed, as shown in Fig. 1. One of each pair of the Wheels 2' is also inter meshed with a pinion j on a transverse shaft 70, which is provided with a gear-wheel l, intermeshed with apinion m on a drive-shaft it.

From the foregoing it follows that when the machine is in operation the cams 1) at opposite sides of the wheels 9 will be rotated in opposite directions, and their peripheries act-t ing alternately against the wheels 9 will reciprocate the follower.

The length of each column of clay expressed or expelled by each movement of the follower cases, not more than equivalent to the depth of the molds prosentl y described and much less than the distance between the ends of the slots f and the extreme ends of the travel of the follower. At least two thirds of the travel of the follower will be taken -up in collecting the loose lumps of stiff clay that fall from a pug'mill (not shown) through conduit 1), and the hollowed faces of the follower will serve to gather the clay inward or toward the longitudinal center of the clay-chamber. In consequence of this it will be seen that there is but little if any, outward pressure of the clay incident to the travel of the follower over covered by the slotsf and but little liability of the clay escaping through said slots. The actual expression or expulsion of the clay through the dice a takes place after the follower has passed the ends of the sloisf. \Vhcn desirable, however, shields of metal connected to and adapted to travel with the follower may be provided to prevent any loose particles of. clay from falling lhrough the slots f. Such shields do not form an csscntial part of the machine, and l have therefore deemed it unnecessary to show the same in the drawings. V

For the purpose of severing cloda or gluls from the body of clay at the ends of the dies a I provide at each end of the clay-chamber a cutting mechanism, such as shown in detail in Fig. (3. 'lhiscuttingmechanismcomprises a blade l l, which may be, and prelim-ably is, a wire, .lZLlQ =LlLY. :.Ul(M l 219 untilh bars 77 thumb-nuts q, which serve to secure thoonds of the wire in the uprights and hold the wire under suitable tension, at strut 1', interposed between and connecti ng the lower ends of the Also fixed on the distance uprights and serving with the same to form a frame, a shaft 5, journaled in the uprights adjacent to the upper ends thereof and having wheels tat its ends, a coiled spring 11,, connecting the strut r and the main frame A, and fixed guides 2), attached to the clay-chamher and receiving the uprights p. The wheels 15 of the cutting mechanism are arranged in a position to be engaged by shoulders w of the cams D, and from this it follows that the frames carrying the blades it will be moved upwardly incident to each revolution of the cams and the same blades will be carried through the clay at points closely adjacent to the mouths of the dies ct. The moven'ients of the parts are so timed that the upward move ment of each blade E will take place a little previous to the movement of the mold-wheel between which and one nipple of the clay* chamber the blade is arranged to move. Gravity may be depended upon to return the cutter-frames to their low position when the wheels t are released from the shoulders of the cams D; but I prefer to employ the springs u for the purpose, since they effect a positive and quick downward or return movement of the cuttenframes immediately following the release of the wheels i from the cams.

,h F are frames which are arranged adjacent to the ends of the frames A and are preferably extended below the lioor-line and mounted on suitable supports, and G G are mold-Wheels arranged in the frames h F, respectively. and fixed on shafts H, journaled therein. The frames 15 F and the mold-wheels G G are similar in constriu'stion, and therefore a specific description of the frame F and wheel (i will suffice to impart a full understanding of both frames F F and both wheels G G. The frame F comprises two upright parallel side walls I, in each of which is provided a cam-track J, the said track being formed between inner and outer wall portions .1; 7 which are connected by angle-irons after the manner best shown in Fig. 1. The wheel. G is arranged between the side walls I of the frame F, and in the preferred embodiment of the invention comprises disks K, fixed on the shaft II and having hubs ct,outer rings I (t and eight (more or less) spokes a, reaching from the hubs to the rings, and transverse frames 1), interposed between and connecled to the rings of the disks. preferably eight of these frames 1), and they are open and Hanged at their inner edges, as shown, in order to enable them to receive and hold mold-boxes o of wood, each box preferably embracing five mold), as shown. 'lhe spokes uf of thedislrs areslotted, as indicated by 0 to receive transverse shafts it, which carry [langed wheels 0, arranged and adapted to move in the cam-tracksJofthe frame 1*, and said spokes a are also slotted, as indicated by j", and provided with flanges 'l'hereaio g to receive and guide follower-bodies L.

"followers i, corresponding to the number of molds in the mold-boxes, the said follower being connected to the bodies in any approved manner and being arranged in alinement with the molds and provided with faces 2' of wood, which form the bottoms of the molds, as shown.

-M is a tappet wheel fixed on the shaft II at one side of the frame F and carrying eight (more oriess) equidistant antifriction-rollers j, the same being properly arranged. with respect to the mold'boxes of the mold-wheel, and N is a tappet, which, as best shown in Fig. 3, is. fixed on the shaft it that is nearest to the wheel M and is-arranged to engage the an tifriction-rollers thereof. It follows from the foregoing that incident to each rotation of the shaft h the tappet N, acting against one of the rollersj of wheel M, will cause the moldwheel G to make one-eighth of a revolution, or, in other words, to rotate such a distance'as will carry one mold-box a certain distance away from a position coincident with one die of the clay-chamber and bring the succeeding meld-box into a position coincident with the said die. Of course the tappets N for rotating the wheels G G are so disposed with respect to each other that one wheel will be at rest, with one of its mold-boxes meeting one die of the clay-chamber 15, while the other wheel is being partially rotated to carry one of its mold-boxes away from and another into regissides of theframc F "ter with theother die of the clayehamber.

The cam-tracks J in the side walls of the frame F arefor the greater part of their length concentrictotheshaftll. 'lheyareprovided, however, at a point above and in the same vertical plane as the shaft II with offsets 7c in their outer walls. Theyare also provided at a point in the same horizontal plane as the shaft If and remote from the elay-chamber with outwardly-extending straight portions Z, from which short eccentric portions l extend downwardly and merge into the concentric portions, for a purpose presently described.

P are reciprocatory horizontal slides or tln'ust-bars, which are disposed at opposite and are provided with elongated openings m, receiving the shaft H, which supports them. These slides are pro vided at their ends remote from the claychamber with depressions or seats n, and they are also provided adjacent to their opposite ends and at opposite sides with antifriction -wheels p 1. (See Figs. 1 and The wheels 1;, which are arranged in bifurcations of the slides, are designed for the engagement of the peripheries of cams D, which serve to move the slides P outwardly or in a direction away from the clay-chamber. The wheels on the slides P are designed for the engagement of cams r on the gear-wheels '21, the said camsr having for their purpose to draw the slides inwardly or in a direction toward the clay-ehamber and being beveled at their forward ends, as shown, to facilitate their engagement with the wheels q.

arms of the bell-crank levers.

Connected to the slides P and extending upwardly therefrom at opposite sides of the frame F are draft-bars Q. These bars at their upper ends are flexibly connected to a cross-head R, which is vertically movable in guides s in the frame-walls land is provided with five (more or less) pressers t, the said pressers being arranged to enter the molds when the latter become coincident with the same and being provided with faces a of wood.

Flexibly connected to the slides Pand normally resting in' a slightly-oblique position between antifriction-rollers or other steps R on the sides of the frame F are pressers or thrust-bars R, which are adapted under certain conditions to assume a vertical position. These pressers or bars R. extend upwardly from the slides and are provided at their upper ends with seats or depressions o, designed to receive the extended ends of the shafts d after the manner hereinafter described.

S are bell-crank levers fulcrumed on lateral arms connected to the frame-walls I and having bifurcations in their upper arms receiving lugs w on the slides P, and T are hangers which are flexibly connected to the lower In the lower ends of the hangers T is journaled a transverse shaft U, which rests below the wheel G and preferably in the same vertical plane as the shaft H. Said shaft U supports a sandbox V of a width corresponding to that of the wheel G and is provided within the box V with blades W. It is also provided at points outside the hangers T with frietion-wheels X,

which are designed to be pressed against friction-wheels Y on a transverse shaft Z, the shaft Z being designed to be constantly rotated through the medium of a belt by asuitable motor or from any shaft of the machine. It follows from the foregoing that when the wheels X are carried into frictional contact with the wheels Y on the shaft Z the shaft U will be rotated and the blades W will throw sand up into the molds of the moldbox above it.

The appurtenances of the mold-wheel G are operated by thecams l) and cams 1' adjacent to said wheel in the same manner that the appurtcnances'of wheel G are operated by the cams D r adjacent to it, and therefore a description of the operation of the wheel G and its appurtenances will'sui'licc to impart a full mnderstanding of theoperation of both wheels and the appurtenances thereof.

As before described, the follower C is reciprocated to charge the molds of the wheel G that are presented to the contiguous die of the clay-chamber with clay, and the wheel is rotated step bystep one-eighth of a revolution at a time and with an interval between each movement. l Vhile one set of molds are coincidentwith'the die of the clay-chamher a previously;charged set are in a position immediately below the pressers 15 of the cross-head E,- anoth-er previously-charged set are at a point diametrically opposite to the clay-chamber, and an empty set are immediately above the sand-box V. Incident to the movement of the follower Gin the direction to charge the set ot molds pre sented to the die of the cla hcherobor the cams D, acting against the Wheelsp of the slides or main thrust-oars P, move said slides or thrustlonrs in the direction indicated by arrow in Fig.1. This movement of the slides or main thrust-bars moves the lower ends of the draftbars Q in the some direction, and thereby draws the cross'head R and the prcsser t downwardly and. presses the upper sides or flats of the bricks in the uppermost set of molds. it also causes the thrust-bars B. to engage the shaft d. of the upper follower body L and assume a vertical position, and thereby simultaneous with the downward movement of the presscrs t" forces the uppermost set of followers i upwardly and presses the under sides or flats of the bricks in the uppermost set of molds in other words, the movement of the slides or main thrust-bans in the direction stated moves the presscrs 15' and the followers 71 in oppositedirections, and thereby subjects the bricks in the uppermost set of molds to great pressure from above and below and renders the same very firzn and still. Such movement of the slides or main thrust-bars 1 also serves by their depressions n engaging the shaft (1 of the follower-body L that is opposite to the clay-chambcr to eject the bricks from the set of molds opposite the clay-chamber. It also serves by rocking the bell-crank levers to raise the sand-box close against the empty lowermost set of molds and to carry the friction-Wheels X. against the frictionwvhcels Y on the oonstantly-rotsting shaft Z, and thereby cause the blades W to raise sand from the box sud thoroughly sand the lowermost set of molds.

Incident to the movement of the cams D to move the follower O in a direction array from Wheel G the cams 'r on gear-'\vlieels '11 act against the antifriction-wheels on the slides or main thrusbbars, and thereby move said slides or bars in the direct-ion opposite to that indicated. by arrow in Fig. 1, and thereby return the draft-bars Q, the thrust-hars R the hangers 'l, and sand-box V to their more nlal positions. As the wheel G is partially rotated subsequent to the operations men tioned, the wheels 6 of the follower-body L that effected the ejectionof the bricks from the set of molds opposite to the clay-chamber traverse the portions Z of the cam-tracks J, and thereby return the said body L and the followers thereof to their normal. position be fore the set of molds reach. a position above the sandbox V. I

In order. to receive "the bricks as they are forced out of the sets of molds at the point diametrically opposite the clay chamber B, l contemplate providing at such point a metal plane or shelf, which 11. have deemed it unnecessary to illustrate. Such plane or shelf may or may not be lubricated; out I prefer to have it lubricated in order to enable a set of bricks ejected from s set of molds to push before them a previously-ejected set of bricks. The bricks may, when desired, be pushed. in

this way onto an o f-bearing truck to betahen away to hacks or Walls for drying.

I prefer in practice to provide the faces ot the pressers t and the faces of the followers t" with a trade-mark, panel, or the like, as in* dicated by 11 and t respectively, since when they ere so equipped they are enabled to press or re-press the bricks and at the same time form a trade-"mark, panel, or any ornamentw tion'in the lists of the some. n

When desirable, a main frcnie common to the clay-chamber and the mold-Wheels may be employed without departing from the scope of my invention bull generally prefer to pro ville separate rames for theclay-chamber end -mold-wheels, as illustrated.

It will be appreciated. from the foregoing that my improved machine automatically,

molds, presses, and ejects the bricks and also automatically sends the molds in a thorough manner prior to the charging of the same with clay. it follows from this that the machine when in operation requires but little attention, which is an important advantage. It will also be appreciated from the foregoing that While the machine is quick-operating its output of bricks is sufiiciently still and firm to adapt it to be innnedistely built up into hacks.

I prefer to have my improved machine embrace two mold-wheels disposed at opposite ends of a clay-chamber, as shown and described; but I do not desire to be understood as confining myself to this embodiment of the invention, as there are certain partsof my improvements that are susceptible of advantageous use-Jinn sin gle-acting machine-that is to say, at machine having a clay-chainber rovided with a single discharge and a single lllOlCLWlleQl arranged adjacent to the said dis-- charge. I also do not desire to he understood as confining myself to the specific construction ant relative arrangement of parts herein shown riiind described, as such changes and modifications may be mode in practice as fairly fall within the scope of the invention.
