22. The upper ends of the toggles are pivoted to a transverse shaft 24 rigid with side frames 26 sliding in the frame 28 of the machine. A lower cross-head 30 rigid with the side frames is connected through suitable known adjusting struc ture with a lower plunger 32 having a die-plate 34, while the lower end of the toggles is provided with a movable plunger 36 and an upper die-plate 38. As the crank I0 reaches its lowermost position, the lower cam-shaped edge 40 of the connecting rod l8 fulcrums on the fixed roller 42, whereby the entire frame and associated plungers are lifted upwardly to cause ejection of the pressed article from the mold '44. Further rotation of the crank causes dropping of the frame to its former position and straightening of the toggles to cause a pressing action.

Means is provided to permit the frame and plungers to drop a short distance after the mold has been originally filled for permitting the introduction of a second layer of moldable material thereabove in the mold. This means comprises a roller fixed to the inner face of the gear I4 and adapted to impinge a bell crank 46 rigidly pivoted to the frame of the machine. The bell crank in turn actuates a lug 48 which, through suitable linkage and counter-shafting, rotates cams 59 through a short are so that the cam depressions 52 are brought above the upstanding spindle portion of the plunger-like supporting member 54. Since normally the frame is supported by this plunger-like member and the spring 56, when this action occurs, the entire frame and plunger and associated mechanism is permitted to drop a distance corresponding to the depth of the cam depressions or the distance between the plunger-like member 54 and the shoulder 58 on the side frames. Immediately after this action has taken place, the members will be in the position indicated. in Fig. 1. When the connecting rod is again fulcrumed on'the roller 42 to raise the frame and toggles, the weight of the parts will return the cam to its original position.

The charging device comprises a reciprocable dual-chambered frame 60 reciprocated by the rod 62 through the agency of a bell crank 64 pivoted to the frame of the machine and actuated by a follower 56 positioned in-the cam slot 68 of the cam 10 rotating rigidly with the shaft I2.

The charger comprises a central transverse partition 12 which thickens progressively toward the base of the charger to form the portion 13, and provides in the charger a forward compartment 14 and a rearward compartment 15 with generally hopper-shaped bottoms. The thickened portion 13 of the partition 12 is machinedaway adjacent its bottom portion to accommodate the pivoted wall 18 extending transversely across the.

bottom of the hopper and being of such width as to permit free entry between the side walls of the mold 44 and mounted rigidly on shaft 80 of the charger.

A transverse strip 82 of thin, resilient material, such as leather, rubber or flexible metal,

- is secured along the forward vertical wall of the thickened portion 13 and is pushed outwardly by the pivoted wall 18 when in normal upward retracted position to prevent the clay or brick making material from clogging adjacent the upper surface of the said wall.

The charger is normally fed with raw materials from a hopper 84 rigidly fixed to the frame of the machine and elevated just sufficiently to accommodate the charger thereunder when the latter member is in its rearmost position. The hopper is divided by a partition 86 into two compartments in the said rearward position, registering in perfect alignment with the compartments 14 and 18 of the charger,

An integral table 88, extending rearwardly from the charger, serves to seal off the bottom of the hopper when the charger has moved forward during its cycle of operation. The rear compartment of the hopper is open at the bottom and, in the position shown in Fig. 2, its contents drop freely into the corresponding rear compartment 16 of the charger. The forward compartment of the charger is provided with a.

plate 96 secured across the bottom and having apertures 92 therein adapted to be selectively opened or closed by'means of a slidable gate 94. The gate is connected with suitable linkage and levers on the hopper and actuated by fixed projections on the charger (not shown) to automatically slide the gate 94 to open position when the charger reaches its rearward limit of travel. The gate controlling mechanism, therefore, permits the forward compartment M of the charger to be filled with raw material from the corresponding forward compartment of the hopper when the parts are in feeding position, as shown in Fig. 4.-

In operation, as the action of the crank ll] of the connecting rod [8 initially flexes the toggles to raise the lower die-plate, the cam slot 68 forces the cam follower 66 radially, actuating its associated mechanism to drive the rod 62 and the charger forwardly and over the lower dieplate, as shown in Fig. 5. As the parts reach the position shown in this figure, lifting of the connecting rod [S by the crank l 0 causes lowering of the entire pressing frame and accordingly the lower die-plate drops with respect to the mold.

As a result the wall 18 is at this time resting solely upon the lower die-plate 34 and as the latter drops, the Wall, through its own weight, pivots about the bearings downwardly to the position shown in Figs. 6 and 7, permitting a limited amount of material from the forward I compartment of the charger 14 to fall downwardly through the aperture formed between the lower edge of the strip 82 and the forward edge of the mold 44. During this movement the charger continues to its most forward position, as indicated in Fig. 6, the upper end 80 of the wall 18 being carried along to the position indicated.

The wall member 18 is so constructed as to have its limit of counter-clockwisemovement in the position shown in this figure, During the forward movement of the charger the wall is permitted to progress forwardly a slight distance after partial filling because the amount of raw material permitted to fall into the space from the hopper 24 is clearly limited by the relatively constricted opening between the strip 82 and the forward edge of the mold.

At this point the limit of the radially extending portion of the cam slot has reached the cam follower and retraction of the charger immediately takes place. Due to the limited opening in the bottom of the rear chamber 16 of the charger,

the portion of. the mold rearwardly of the wall 18: will be fill-ed substantially in the manner indicated in Fig, 7, the material at the forward side thereof forming an inclined surface 95. As retraction commences, the wall 18 rides up this inclinedsurface 96 in the manner shown in Figs.

6 and 7. Substantially at the time withdrawal of the hopper commences, the roller 45 on the gear wheel I l impinges the end of the bell cranka it,

moving the cams 50 through an arc sufiicient to bring the cut-away portions 52 in registry with the stem of the plunger-like support member. Accordingly, the entire frame 26 and associated pressing mechanism drops a predetermined distance as indicated by the space below the portion 13 of the charger, in Fig. 8, permitting space for the application of the veneer to the upper surface of the brick. As further retraction takes place, the wall 18 is finally, through contact with the rear edge of the mold, moved to full retracted position, as indicated in Figs. 10 and 11.

Further actuation of the toggles brings the op posed plungers together to finally press the brick, as indicated in Fig. 11. The brick thus made comprises a main central body portion 98 having an endface of a contrasting lamination Hill and a side face of a contrasting lamination ill-2, the

two laminations being joined interiorly in a relatively curved line. I

While the wall 78. shown in Figs. 4 to 11, is formed of sheet material of'relatively uniform thickness, the wall forming the alternative preferred embodiment of Fig. 2 is provided with a lug or projection extending alongv the free lower edge thereof. In using raw materials which may tend to be dragged beneath the retreating edge of the wall, this lug 19 tends to maintain the space at the top of the mold for placing the top layer of material from the chamber It. The,

lug I9 is so shaped as to be projected upwardly upon contact with the rear edge of the mold, to permit full retraction of the charger.

According to this invention, it is possible to produce brick having a central portion 98 comprising the main mass of the brick, formed of a relatively inexpensive grade of raw material, While the outer surfaces, provided by the portions Hi0 and I02, may comprise a raw material, the relative cost of which is so great as normally to prohibit or limit its use in making solid bricks therefrom. Thus in operation the forward hop-- per, and accordingly the forward compartment 74 of the charger may be fed with a supply of the relatively costly material, while the rear hopper and compartment T6 is supplied with the common brick making clay or the like,

According to the alternative preferred embodiment disclosed in Figs. 13 to 22, means is provided for supplying the mold separately with contrasting bodies of raw material and for dropping a movable partition vertically between the con-- trasting bodies in order to produce a sharp ver tical line of demarcation.

The machine employed may be the same device as that disclosed in illustrating the previous as pect of the present invention, with the exception of the charger, although it will be preferable to vary slightly the timing and co-ordination 7 of the various actions in a manner which will be obvious to anyone skilled in the art after a perusal of the instant specification,

The charger comprises front and rear comconnected together by a plurality of welded pins or.rivets I04, as indicated in Fig. 17. A gate or partition I06 is arranged to slide vertically between the sides of the split partition.

The gate, as will be apparent from a view of Fig. 13, is formed with a series of downwardly extending tongues or partitions I08. The embodiment disclosed provides for pressing four bricks at each cycle of operation, there being, as shown in the figures, three juxtaposed molds. Each tongue I08 corresponds to one of the molds and is of proper width to fit readily within its respective mold. The pins IM are situated in slots above the respective partitions or tongues I08 and permit free vertical movement of the gate I06 within predetermined limits. The gate extends laterally beyond the sides of the charger and is provided at each edge with forwardly and vertically extending racks I69. Each rack is normally engaged by a respective pinion i If! secured rigidly to a sleeve I I2 and mounted for rotation upon the shaft IM of the electric motor I I6. Adjacent the motor a relatively steep spiral groove H8 in the motor shaft 1 M- is engaged by a tooth or thread segment I28 formed rigidly on the interior bore of the sleeve H2.

A bell crank I22 pivoted at I24 has a rearwardly projecting bifurcated arm I26. pins #28 on this arm oppositely engage an annular groove in the sleeve H2. The motor H6 is rigidly secured to a bracket I30 which is fastened to the side of the hopper and the pivot IM: for the bell, crank is positioned upon an arm 132 forming a rigid part of the bracket I30.

, Due to its engagement with the pinions lit, the gate I lit is normally maintained in its uppermost position. I Means is pro-vided to release the.

gate from engagement with the pinions I ID at the forward end of the movement of the carriage and; comprises a lug I34 projecting from the frame of. the machine in such position as to contact the .end of the bell crank I22, as shown in Fig. 15,

when the charger is in its foremost position, and move it about its pivot in a clockwise direction. Accordingly, the bifurcated arm I26 and the opposed pins I28 are moved downwardly, as viewed in Figs. 15 and 16, sliding the sleeve H2 and the associated pinions in the same direction with respect to the motor shaft IIB to the final position shown in Fig. 15. The gate IE6 is now capable of falling by its own weight when so permitted.

Further means is provided to actuate the motor to raise the gate when it falls by gravity, and consists of a motor switch I36 and a pair of pins I38 rigidly secured to the gate I06 adjacent one of the racks. As appears in the figures, the control means are positioned so that, when the gate drops, the upper pin I38 will impinge the switch and force it to closed position, starting the motor. Rotation of the motor shaft relative to the sleeve II 2, due to the inertia and frictional resistance of the latter, forces the sleeve axially (in an upward direction, as Viewed in Fig. 15) until the pinions I ll] are in engagement with their respective racks I09. Further rotation ofthe shaft H4 raises the gate upwardly from the mold. When the gate has risen to the position shown in Fig. 14, the lower pin IilB contacts the underside of the switch Mil, breaking the circuit and shutting off the motor.

The operation of the machine (referring to Figs. 19 to 25) is as follows: In the initial position, the charging member is located at the rearward end of its path of travel and is supplied by manual means or any suitable means with brick-making material.

In the instant device, the material forming the main body of the brick is supplied in the forward chamber 14, while the material for the veneered surfaces is supplied in the rear chamber 76. The plungers of the press will be initially separated and the bottom plate 34 will be flush with the top of the mold, as indicated in Fig. 19.

At this time the action of the cam 10 and. follower 66 causes the charger to be moved forward uniformly and rapidly to its foremost position, namely, the position shown in Fig. 20, in which position the bell crank I22 is impinged against the projection IM to move the sleeve II2 axially to the right, as viewed in Fig. 17, and release the pinions IID from engagement with the racks I09. At this point rotation of the crank I0 raises the crank end of the connecting rod, permitting the frame 2'5 and the plunger 32 to drop downwardly, as in Fig. 20, to the position shown in Fig. 21. The gate IilIi at this time being slidably positioned in the partition member I2 and free to move under the influence of its own weight,

drops with the plunger 32 and the lower platen 34, as shown in Fig. 21. Meanwhile the brickmaking materials from the respective compartments l4 and T6 of the charger likewise fall downwardly into the space formed in the mold by the dropping of the die-plate. The gate I06, as aforementioned, substantially divides the mold into two sections, the forward section being filled solely with'material from the compartment M, while the remainder of the mold consists of material from the compartment 16.

At this time the upper pin I38, impinging upon the switch I36, actuates the motor shaft lit to start rotation in the shaft H4. The sleeve accordingly is moved rotationally and axially with respect to the shaft H4 until the pinions I I0 engage their respective racks I09. From this point rotation of the shaft and sleeve as a unit causes elevation of the gate I06 to its upper position, as shown in Fig. 22, at which position the lower pin I38 switches off the motor, as hereinbefore described. Withdrawal of the gate I36 will permit a clear line of demarcation to remain between the materials forming the main body of the brick 98 and the portion I03, corresponding to the veneered end thereof. It will, be obvious that the cam "l0 must be so positioned as to permit the charger to stop momentarily in the position indicated in Figs. 20, 21 and 22 for the purpose of permitting the above action to take place.

Subsequently the carriage is moved relatively rapidly rearwardly to the position shown in Fig. 23. When substantially this position is reached the roller 45 contacts the bell crank 46, actuating the lug 48 and the cams 5D to permit the entire frame 26, including the bottom crosshead 3D and its associated parts, to drop a distance indicated in Fig. 24, the forward compartment M being positioned immediately over the mold. The space created by the dropping of the frame will be filled with the veneer material from this compartment, and as the charger continues its rearward movement the front edge thereof will level off the material flush with the top edge of the mold. This action having taken place, as shown clearly in Fig. 25, the upper plunger 36 is brought downwardly under the influence of the straightening of the toggles 22 and 24, to compress the material in the mold into a brick of the proper slze.

After ejection from the mold the article may be dried, fired or otherwise treated in any conventional manner. The final article, as it appears in Fig. 3, will comprise a main body portion 98, formed of the material originally fed to the rearward compartment 16 of the charger. A relatively thin lamination or layer of material from the compartment 14 is integrally associated with the remainder of the brick. A second integral lamination forms one adjacent face portion I02 of the brick. It will be noted that due to the positive action and separation of the relative bodies of material during manufacture, the laminations of veneer are sharply separated from the body 98 of the brick-making material by welldefined, straight, plane surfaces.

The present invention provides a ready means for manufacturing brick having composite veneered portions that is particularly suitable in the manufacture of pressed brick wherein the exposed surface portions only are to be formed of a relatively costly material. It will be obvious that various equivalent means may be employed to cause proper apportioning and placement of the various layers of raw material into the mold. While certain forms of separators have been disclosed for this purpose, various other devices will be operative in accordance with the present invention.

It is not necessary with all raw materials to bring the separator into action completely across the length and depth of the mold. On'the contrary, action through only a portion of the vertical distance shown in the figures will be sufli cient in many cases to properly direct the materials substantially to the positions shown in the figures. Moreover, the present invention may be employed for pressing or forming various other articles aside from bricks, and can be adapted in accordance with the above disclosure to the formation of veneered or layered portions of widely varying proportions and relative positioning.

The term brick as used in the instant specification and claims, is not employed in a limited sense but is meant to cover ceramic units such as floor brick, paving brick and fire brick, as well as materials generally known as tiles and other elements formed of clays, aggregates and the like and bound together in a unitary mass.

It is thought that the invention and numerous of its attendant advantages will be understood from the foregoing description and it is obvious that numerous changes may be made in the form, construction and arrangement of the several parts without departing from the spirit or scope of the invention, or sacrificing any of its attendant advantages, the form herein described being a preferred embodiment for the purpose of illustrating the invention.
