A represents a plastic clay brick making machine of any suitable form or kind. In the drawingsI have illustrated a form of the same known as the Henry Martin machine as it is the one now most commonly used and the construction and operation of which are well known. A represents the'delivery end of said machine, B the shaker device, '0 the knocker arms for the shaker device. E the dumper device, D the transferring devices between the shaker and the dumper, F the stacker device, H the mold sander device, G the transferring devices for conveying the dumped or empty molds from the dumper device to the m old sander machine, K the transfer devices for conveying the sanded molds from the sanding machine to and inserting them into the brick making machine. All of these devices may be constructed and arranged relatively to one another as desired, or the demands of service require, as their general or detailed arrangement and their construction, operation and actuating mechanis'm may be greatly changed for accomplishing the purposes of my invention without departing from the spirit thereof, and hence I do not limit myself to the various arrangements and constructions of the forms herein shown and described.

The shaker device B consists mainly of a table or platform 5, which has a to and fro motion from end to end across the front of the brick making machine or its delivery platform, to cause the ends of the mold to alternatelystrikethe oppositelylocated knocker arms C, to loosen or shake the bricks in the molds preparatory to dumping them. The table I) may be of any suitable construction. In the drawings, see more plainlyFig. 5, it is shown provided with reduced ends b, having upwardly projecting edge flanges b These reduced ends pass into openings or recesses c, in the knocker arms 0, so as to admit of the ends Z of the long sides l'of the molds L striking the knocker arms 0, without the plate I), hitting said knocker arms. With this construction the impact of the blow falls upon those parts of the mold best able to resist or endure it, thereby providing for maintaining the durability of the molds, the same as in hand shaking.

The table or platform I), in Figs. 4. 6. 7 and 11 is shown having a rod connection 11 with a second plate 19 sliding in suitablelugs, and provided with interposed buffer springs b to compensate for shocks and concussion. In Figs. 4 and 6 the second table or platform 5 is shown provided with a roller support b, being held or guided thereon as indicated more plainly in Figs. 6 and 7, or such support may be otherwise provided for as desired. With this construction the plates b, b, and the mold L on the latter are simultaneously moved to and fro, but as the plate I) and the mold are independent of the table 11 by reason of the sliding rod connection I) with the interposed buifer springs 6 the table I), and actuating mechanism and engagement therewithare almost wholly free of the impact or strains incident to the striking of the ends of the molds against the knocker arms.

Any suitable actuating mechanism may be employed for imparting the to and fro movement to the table b.preferably a form of the same is used which will give the table the required number of reciprocations for properly shaking the molds and then bring the table and mold to rest or dwell to admit of the mold being moved from the table to the devices D, which transfer it to the dumper device.

In Figs. 9 and 10 is shown a disk or wheel 12 attached to actuating shaft b and having an actuatin and dwelling roove b which D b I by a cross bar I), which has a direct engagement with the actuating and dwelling groove b and disk b In Fig. 13 the table I), is indicated as having a wheel or roller support on the fixed end of the brick machine, and the lever 11 is provided with the sliding rod connection 12 in engagement with said table by means of vertically arranged rollers or bars I), the buffer springs b beinginterposed as shown. By providin g an angularly arranged slot 11 lengthwise of the fixed delivery end, as shown more plainly in Fig. 14 through which the rollers D pass, the table I), and the mold thereon are simultaneously moved to and fro, lengthwise and laterally, or angularly reciprocated for correspondingly striking the knocker arms C, which has the effect of loosening the ends or heads as well as the sides of the bricks in the molds.

In Figs. 15 and 16 the table b,is shown pro vided with an extension pivoted at I), said extension having suitable buffer connection with the actuating devices as desired. In this last described form the table 12 has a curvilinear reciprocating motion.

It will be noted that in all the forms of shakers B illustrated and described, the shaker carries with it the mold and the power devices move both the shaker and mold, but it is obvious that the mold and shaker may be otherwise relatively arranged and the power appliances actuated to shake the molds as de sired.

The molds L, with their open tops are projected from beneath the strip or bar a, of the machine A, in the usual orany desired manner. As they are delivered from the machine they successively pass onto the shaking table Z), which is then normally at rest to receive the molds, the mold previously shaken being pushed oif of the table I), by the succeeding delivered mold. As the shaken mold passes 0E of the table I), it is conducted to a moldreversing device D, which is a part of the devices D, for transferring the molds from the shaker device B to the dumper device E. Any suitable form of mold reversing device D may be employed. In Fig. 17 an intermittent rotary form is shown, consisting of a shaft 01, end

frames 01, said shaft having any suitable actuating mechanism, a pawl and ratchet device cl for instance, having a sliding bar (1 and cam d engagement, on shaft 11 if desired. The end frames d, of mold reversers D, are provided with radial slots (1 wide enough to receive the molds and pallets as they are fed thereinto. The bottom sides of these slots d when at rest in front of the shaker device are level with the top of the table I), and into each of these slots as they successively arrive into their receiving position in front of the shaker device is conducted a mold coming from the shaking table. Preferablyin order to facilitate the quick transit of the molds from the shaking table 1), into the recesses (1 and to provide for a side blow of the mold against the inner ends of'said recesses (i for shaking the brick lengthwise to loosen its head from the molds, suitable revolving rollers one or more as indicated at 0, are interposed between the shaker device 13, and mold reverser D.. These rollers are suitably mounted in the delivery platform of the brick machine A for instance, and are in engagement with an actuating shaft 12 if desired, for imparting to said rollers a speed much higher than that of the travel of the molds from the machine. This high speed conducts the mold from the shakertable b, and into the receiving recess d of the reverser D, with sufficient velocity to cause the mold to travel to and strike the rear end of the receiving recess with the required impact for loosening the heads of the brick from the mold. As the mold passes into the receiver recess of the reverser D, a pallet a of the usual or other suitable construction is placed upon the top of the mold. The pallet may be put on the top of the mold before it enters the recess, which ifdesired may be manually done. The position of the pallet on the mold in this case is with the top or face contiguous to the top of the mold, the

feet of the pallet projecting upwardly. The distance apart of the frames d of the rereverser D is such, that they are adjacent to and form guides for the inner sides of the feet of the pallet so that as the mold and pallet pass into a recess (1 the pallet is properly adjusted lengthwise relatively to the mold. To insure quick feeding of pallets into the recesses CF, I prefer to do the same Inechani cally. To this end a suitably located pallet receiver or supply receptacle a is provided. This is shown hinged or swung upon suitable supports above the shaker device and mold reverser D, and it has an oscillating motion to and from the receiving recess 01 of the reverser D; In the form of receptacle or shown it is provided with an open bottom 0. hinged at its rear end to the receptacle as indicated at a. See more plainly Figs. 18 to 21' inclusive. The bottom a has reaction devices a for holding it normally closed, a rear inner lower edge a and front inner and inwardly projecting short pins or studs a. This ledge and these studs support the pallets placed in receptacle 00 with their feet upwardly, as indicated more plainly in Fig. 17. The front side a at its lower end is cut away or opened equal to the depth of the pallet as more plainly indicated at a, Fig. 20, which opening is provided for the escapeof the pallet as it is fed onto the mold in the receiving recess of the reverser D. The receptacle (L24 is so hung that as it approaches a recess (F, the lower pallet in the receptacleis in line with the top of the mold as indicated by dotted lines 00 Fig. 18, so that when the outer edge of said pallet meets the top of the mold, and the upper edge of the receiving recess (1 the hinged bottom a yields to permit the forward oscillation of the receptacle 0., to carry the pallet in astraight line into the recess to the full limit thereof and properly position the pallet on the mold as indicated in Fig. 19. As the receptacle a the succeeding pallets therein. Any suitable crank and link connection a, with a like crank on an actuating shaft 5 for instance may be employed for oscillating the recepta cle c1 At each movement of the mold reverser D is withdrawn, the bottom as closes to retain from the pallets to dump the brick. When the reverser brings amold and pallet into delivery position, the feet of the pallet'come onto parallel ways or guides d Fig. 22 and the body of the pallet is adjacent to an endless apron or traveler (1 located between its feet, or the ways (1 This traveler or apron d is provided with outside transverse cross strips I or fingers 61 preferably of a form in cross section that they will meet and abut against both the pallet and the mold as they are brought into delivery position by the reverser D, for transference to the dumping device E. As

the pallet feet rest on the ways 01, the weight of the pallets and molds are removed from the traveler (Z The latter is actuated by a belt or other connection from the actuating shaft b or otherwise as desired to give it an intermittent motion corresponding to that of the reverser D. A reversed mold and pallet conveyed to the dumper device are brought into alignment with mold elevating devices IOO e, having'an up and down motion on a suitable frame 6 and actuated by suitable cams e on shaft 6 through the medium of bars e said shaft 6 having if desired a belt connection c with the actuating shaft 17 or otherwise as desired.

When the form of mold shown in Fig. 32 is used as it is at present customary, that is to say, with the handles Z at the top of the molds, the elevating devices 6 are provided with pivoted or movable catches or fingerse, having suitable reaction devices for maintaining them in normal position to engage the handles of the mold and lift it from the brick when the devices 6 are elevated. See more plainly Figs. 29 and 31. If the mold be made as illustrated in Fig. 33, that is with the handles at the ends at the bottom of the mold, rigid fingers e are employed for the elevating devices 6 as shown more plainly in Figs. 3 f and 35. As each succeeding mold or pallet is delivered to the dumping device, its elevating mechanism e engages the ends of the mold, and elevates it from the pallet,

leaving the brick thereon, which pallet and brick are by a succeeding movement of the traveler or apron d removed from the do mper device, from which apron or traveler the pallet and brickmay be manually taken and placed on cars, trucks or otherwise disposd of as desired. The mold when elevated from the pallet may be manually removed from the lifting devices e and returned to the sanding machine. I prefer however to mechanically return the empty molds to the sander and to this end, the frame (2 of the dumping device in line with the path of upward movement of the molds is provided with hinged or pivoted guide ways (2 having lower inside cammed edges a against which the top of the mold strikes to spread apart these guide ways and admit of their returning to their normal position below the mold after being elevated. These ways are preferably inclined and provided with roller bearings so that when the mold is free to do so, it will by gravity travel along said guidesto other or fixed guides g, or the guides 9 may be a traveling apron as indicated at 9' Fig. 31. The guides g, see more plainly Fig. l are located transversely across a traveling apron which leads to the sanding machine H, so that an empty mold traveling along the guides g is deposited on the apron g and by itcarried to the sander H; a suitable buffer 9 at the ends of guides g limits the travel of the mold on said guides so that it will fall from the guides onto the apron g in proper position to be transferred to the sander. Any suitable form of sander maybe used.

In the drawings I have illustrated a sander, composed of the shaft h, upon which are end wheelsh having outer belt or fixed sheathing h The shaft h is preferably hollow as shown more plainly in Figs. 43 and 4:4, and one end is provided with a hopper h swiveled to the shaft at 71. and into which the sand is manually shoveled or conducted from the grinder or place of supply. The sand from the hopper passes into the hollow shaft h, and through openings h therein falls into the sander. Any suitable spiral or analogous conveyers h may be located in the bore of shaft h to assist the passage of the sand through the same. The wheels h are provided with radial lugs h which engage the endsofsuccessive molds asshown more plainly in Fig. 43, and carry them through the sander up to and on the plate h from whence they are transferred by roller or rollers h having belt connection h, see Fig. 1-with shaft b or as desired. The molds so delivered from the sander are bottom upward and must be reversed when inserted into the brick machine, and to this end the rollers 72 conduct the successive molds to a reversing plate k, having a front upwardly projecting ledge 7%. This plate is so pivoted at that its rear end k overbalances its front end to return it to its normal or horizontal position, to receive the mold. The weight of the latter on the plate causes it to tilt at its forward end to turn the mold over so as to bring its open side up and deposit it on a traveling apron or conveyer 10 leading to the entrance opening 70 for the mold in the machine A. Suitable guides 71; 7& parallel and adjacent to the edges of the traveling apron 7.3 are provided for positioning the reversed mold as it drops onto apron 7t" and also during its travel thereon and insertion through the opening 70 into the machine A. p g

The roller or rollers h are preferably high speeded so as to cause the molds to be quickly conducted to the tilting plate lain order that it may have sufficient time to perform his function and return to normal position to receive the successive molds, fed onto the plate h by the slower travel of the wheels h It will be noted from the foregoing that the moldswith the brick as they are successively delivered from the brick making machine are mechanically shaken and dumped, and the empty molds are correspondingly returned to the sanding machine, sanded and properly positioned for mechanical insertion into the brick making machine, thereby dispensing with the services of shaker, dumper and a sander man for those purposes. The output of the machine is therefore not limited and may be increased to the full capacity of the brick making machine and the molds are uniformly shaken and dumped with precision, preserving the form and shape of the brick and insuring the production of regular and better stock,all of which is accomplished at very material reduction in cost.

I have stated that the dumped bricks carried forward by the traveler a may be mannally taken therefrom and stacked on cars. I prefer that the same should be mechanically done as quicker and better stacking can thereby be effected without damage to the stock and the high priced labor usually employed therefor is dispensed with.

The essential requirement of the mechanical stacker is that it must be so constructed that it can be raised with the growth or piling of the stack, and can be contracted or extended as the variant locations of the different pallets in the different stacks necessitate. The stacker F is therefore pivoted or hinged so that it can be gradually raised from the bottom to the top of a stack and then quickly lowered to begin the succeeding stack. It also is made in sections so that its length can be expanded as it is raised in building the stack and contracted as required in directing the central and the outer stack next to the stacker.

In Figs. 1 and 2 a form of stacker is shown located in front of the traveler or apron e and connected thereto by a framef provided with aprons or traveling chains f to continue the movement of the pallets with the bricks thereon to the stacker, and also to provide for freedom of pivoting the stacker so that it can be raised as the growth of the stacks require.

F after each succeeding pallet has been deposited in the stack, suitable pawl or other retaining devicesf being provided for engagement with the gears f for retaining the stackerin its raised position. These pawls are released manually or otherwise when it is desired to lower the stacker after the comple- 7, tion of a stack. The form shown in Figs. 1

' the stack.

and 2 is providedwith one movable section f having traveling bands or chains f racks f in engagement with a gear wheel 0 mounted upon a shaft 0 supported in the frame f and having an operating winch or handle f whereby the front end f of section f is projected away from or brought to the frame f to extend or contract the stacker as desired. Upon the shaftf at the front end of the section f are loosely mounted ways or guides f which are so hung that they maintain themselves or are held in a horizontal position relatively to the variant positions of the stacker. Said shaft is provided with wipers f which rotate with the shaft. The pallets withbrick thereon conveyed to the stacker are successively caused to travel to the front end of the stacker, and out upon the Ways or guides f by means of the bands or chains f, the wipers f moving the palletsoff of the ways-f to effect their stacking.

When-the waysf are constructed as shown in Figs. 1' and 2 the ways fare withdrawn from beneath the pallet after it is stacked by manual manipulation of the stacker. If the pallets are. constructed with their feet re moved slightly from their ends as shown in Fig. 3 and the ways or guides f be hinged or pivoted to the section f then the guides may in any suitablemanner, either by gravityor mechanically be moved laterally out froinbeneath the pallets as indicated by dotred lines in Fig. 3 without necessitating any manual operation ofthc stacker f 4 releasing said Waysor guides from the pallets preparatory to stepping the stacker.

In Figs. 36 to 39 inclusive a form of stacker is shown having two or more extensible sections and which more plainly show how the bands or chainsf are elongated or contracted correspondingly with like movements of the sections of the stacker, said bands passing around a floating weighted sprocket or other cylinder f. In these forms the outer section f is provided with a traveling carrier T,

which engages pallets and conveys them to The traveling carrier T has its movements on tracks 25, and is provided with hingedcatches t, which engage the pallets as shown more plainly in Fig. 37. Suitable trippers t are provided for releasing the catches from the pallets in the act of depositing them upon the stack. The carrier T is moved to and fro by traveling band 15 actuated by the shaft f of section f through intermediate mechanism i The traveling carrier T may have an up and down motion also, in addition to its to and fro movement as illustrated more plainly in Figs. 36 and 37. When it has a to and fro movement only, it is connected to the traveling band i as shown in Figs. 39 and 40. The ways f in these forms are of short length and do not extend to the line of the stacks. Said ways, carrier T, its tracks, driving belt t and power transmitting devices t are all mounted in a suitable frame 15? pivoted or hinged on the shaft f of section f 8 so as to maintain its horizontal position relatively to that-of the stacker, such maintenance beingprovided for by suitable gravity acting devices or by levers,links mechanical or other suitable appliances. desired the sections of the stacker may be tubular as illustrated in Fig. 42,- In these forms of stackers the gear Wheel f for stepping stacker is not mutilated and such stepping movements are controlled by friction or otherclutching mechanism m, the gear wheels f beingloose on their-shaft. See more plainly Fig. 41.

In Fig. 45 is shown a roller N preferably mold. Saidroller is mounted in a hinged.

IOC

frame at and has pressure devices 11/ for regulating the degree of its rolling pressure upon the brick in the mold. Said roller is pro- Vided with a scraper 02 having pressure screw 01 andwith a"pressure"iorush or pad 71 for keeping its surface clean and bright, thereby preventing the brick adhering to the roller, I

and admitting of it eifectually accomplishing its functions.

the roller does not comeinto actionuntil after the moldis ejected from the machine or from beneath the scraping knife or device. The knife or scraper and the roller N are acting The roller N, it will be noted, is so mounted in its supporting framen, that upon different molds at the same time, or in other words, the roller N is smoothing the top surfaces of the brick in a mold in advance. of the one being ejected from the machine and acted-upon by the.scraper. The actions of scraping and rolling the green brick in the molds, are, therefore, successive actions and a not, simultaneous ones as heretofore has been the case, and all crowding or banklng of clay againsttheouteredgeof the scraperisavoided.

In Fig. 27 a modified form of carrier reverser D is shown which consists of a tilting plate 19 weighted at its rear end to return it.

normally to a horizontal position, and of a second plate 19 tilting on a sliding carriage 11 The rear end of plate 19 is weighted to bring it normally to an angular position. A mold fed to theplate p overbalances its front end and tilts it in the direction of arrow 1 Fig. 27. As such tilting occurs the inclined plate p' is approaching the plate p, and is in posltionto receive the tilted mold upon the pallet previously placed upon the plate 19. As soon as the tilted mold impinges against the pallet on the plate 19' the Weight of the mold tilts plate 1) to a horizontal position, thereby reversing the mold, and a carriage p is then actuated to convey the pallet and mold to the dumper device.

In Fig. 47 is shown a modification of location of the dumping device in which the latter is located in front of the sander, instead of in front of the brick machine, in which case a traveling band R conveys the molds, after they. have descended by gravity from the partial platform 1", to the mold reverser D. In this position the ways or guides 9 will lead directly into the sander and the travelng belt 9 be dispensed with. So too, traveling aprons may be substituted for said guides, the use of either depending upon the relative height of the sander, mold reverser, and dnmper device.

In Fig. 48 is shown a modified form of dnmper device consisting of a continuously traveling apron chain or belt, V, to which are attached the elevating devices c, which run on tracks as shown. The traveler V has the same speed as the traveler (1 which in this case also runs continuously. The front end of traveler V is higher than its rear end,and the tracks for the elevating devices are correspondingly arranged, so that as the latter are moved by the traveler when in engagement with the mold, up the inclined tracks and in so moving the elevating devices and mold are raised from the brick.

Fig. 49 shows the detailed construction of these last described elevating devices, and trippers for releasing them fromthe molds when they are conveyed to the guides or aprons g, 9 for transfer to the sander.

While I have described my invention as being particularly applicable to softmud brick making machines I do not confine myself thereto, as so much of the same as is necessary may be used in connection with stiff mud brick machines wherein the brick is placed upon pallets and stacked upon cars.

It will be noted that in the operation as a whole, the mold L is first delivered to the shaker B, which shakes the mold, The shaken .mold is then passed to the transferring device D, and supplied with a pallet and turned top side downward with the pallet in position upon the belt or apron d The lattermoves the mold and pallet to the dumper E. The mold is raised from the bricks and passes by way of the transferring devices G to the sander H, and from the latter by way of the transfer devices K to the brick machine. Meanwhile the pallet of dumped bricks passes by way of the belt or apron d to the stacker I and by it is stacked upon the car.
