One of the objects of this invention is to produce a mechanically-actuated press which will be capable of mechanically producing trim tile,
such as heretofore hasbeen made only in hand-- operated friction-drivenpresses. Trim tile so made on our mechanically-actuated press will whenfinished be as firm, strong and uniform in structure .as theltrim tile made on frictiondriven presses and. will be useful'as edging tile, such as cap tile or base tile in tile panels.
Another object of our invention is to provide in a press of the character specified, special cooperating heads on the upper and lowerplungers of a presswhich are provided with cooperating depending and upwardly projecting portions to press edge-ribs on trim tile within a 'die cavity, mechanically-actuated 'means on the press for elevating the lower plunger after pressing a trim tile to raise the lower plunger into a tile-ejectable position above the die cavity, andmechanicallyactuated means operable first to 'push such pressed tile across said plunger and die cavity and thereafter having a secondary movement to transfer the pressedtile out of the press and for introducing or, charging clay in suitable quantity and disposition into the die cavity to produce-a trim-tile Another object of our invention is to provide in combination with a novel tile-ejecting and charging means that will have tile-ejecting movements adapted to initially move a tile across the lower'plunger of the press and out of the die cavity, of mechanical means for transferring the tile from a position adjacent to the die cavity to an off-bearing belt, and also to introduce and properly dispose acharge of material suitable for forming or pressing a trim tile.
Still another object of our invention is to provide a combined charging and ejecting mechanism adapted to have a primary tile-pushing movement and a secondary die-charging movement adapted to actuate a tile transfer mechanism whereby a fragile tile, such as a trim tile, will first be slidably pushed a hort distance from the die cavity and will thereafter be carried on a transfer mechanism to an ofi-bearing belt.
Another object of our invention is to provide a transfer mechanism having a reciprocating movement from a position adjacent to the die cavity to a position adjacent-to an off-bearing belt and return, and means; preferably comprising a combined ejecting and charging device, for actuating said transfer mechanism to have a tile-transferring movement from said position adjacent to the die cavity to an off-bearing belt, and a resetting movement from the off-bearing belt to a position adjacent to the die cavity.

(01. 25-94) chanically-actuated tile press, to provide an ejector and charging mechanism having a novel cycle of movements synchronized at an intermediate position in such cycle of movements with the movement of .the ribbed plungers hereinabove specified, whereby an initial quick forward movement thereof will push and move a previouslypressed tile over a part of the floor portion of the lower plunger away from the die cavity and into contact with a transfer mechanism while the lower plunger is raised and the upwardlyprojecting rib thereof extends above the level of the die cavity to obstruct a complete forward movement of. the ejector and charging mecha- L nism; then will have adwell or stop in such forward movement timed with a downward lowering movement of the lower plunger to its normal tile-pressing position which lowers said rib and removes the obstruction, thereafter will have continued forward movement rapidly to actuate said transfer mechanism to transfer the pressed tile to an off-bearing belt and also to charge the diecavity, and finally having a :backward, return movement to reset the transfer mechanism and procure another charge of clay.
Still another object of. our invention is to provide a tile-transfer mechanism, preferably actuated by a combined ejector and charging device, comprising a grill of spaced bars adapted in an initial position adjacent to the die cavity to re-v ceive and support the tile during the initial ejecting movement thereof, and thereafter to move from said initial position to a position adjacent. to the off-bearing belt, and in such movement notonly to support but to carry the tile from said initial position to final position and then to deliver the tile into contact with the ofi-bearing belt.

Referring now to these drawings which illustrate a preferred embodiment of our invention, it will be understood that our mechanical-actuated press for trim tile has certain general features similar to presses employed in the manufacture of flat tile, as for example, the mechanical and hydraulic presses illustrated in expired patents to Yingling #1,268,909 and #1,515,918; and reference is made to these patents for such features and details thereof but in our press the construction and movements of various parts have been modified, new parts have been employed and new functions have been provided for some of the parts, as hereinafter specified.
Our improved press embodies a main supporting frame including side members I provided with suitable bearings for shafts and other parts. A main conventional power-shaft 2 provided with the usual control mechanism, is mounted in bearings in said supporting frame, a mold-casing 3 for the die cavity, a lower plunger or die 4, which in .our press has a special head 4 suitable for pressing trim tile and provided with a body or floor portion 4* and upstanding rib 3, an upper toggle-actuated plunger 5 having a similar cooperating ribbed head 5 provided with a body portion 5* and a downwardly projecting rib 5, a pitman 6 connecting the die toggle with a crank on the power shaft 2, and a clay reservoir or hopper "l. Areciprocating tile-ejecting and moldcharging device or shaker box is adapted to be operated to move forwardly and rearwardly by cam mechanism actuated by the shaft 2 to convey a charge from the hopper I to the die cavity of the mold casing 3. This tile-ejecting and mold-charging'device and its operating cam, in accordance with our invention, has a novel forward movement adapted to cooperate with a modified movement of the lower die and with a novel transfer mechanism hereinafter more particularly specified which is arranged closely adjacent to the die cavity and said forward movement of the charging device is divided (1) into an initial relatively rapid movement for partial ejection or movement of a previously pressed tile causing a forward pushing of the tile over or along the surface of-the lower plunger head and over or along the top surface of an anti-friction transfer mechanism, and this initial movement is timed to occur while the head of the lowerplunger is moved and positioned above the level of the die cavity and in a position which would obstruct a continuance of such movement; (2) a dwell or stop in said forward movement synchronized to permit downward movement of said lower plunger "head into normal tile-pressing position to free the path of said ejector and charger device; (3) .a subsequent secondary relatively rapid forward movement of said ejecting mechanism adapted to charge the die and to actuate said transfer mechanism to move the pressed tile to and into contact with an off-bearing belt, and (4) a continuous return movement to loading position.
A support 8 for the lower die 4 i carried by .a conventional pair of complementary and vertically slidable side-bars 9 fitted in suitable guides on the frame members I, and a shaft l 0 comprising a pivotal support for the upper member of a toggle H is mounted in bearings in the bars 9. bearing portions I 3 of the shaft ii) are positioned eccentrically to the intermediate body section and to one end of the shaft 10 is suitably secured a crank l2 which is connected by a rod l2 with one arm of a bell crank 14 mounted on the frame of the machine and having it o-ther arm provided with a roller I 5 with which a earn !6 on the power shaft '2 cooperates, whereby the eccentric togglesupporting shaft I!) will be rocked in its bearings during each rotation of the shaft 2.
The connecting rod l2 preferably is of conventional construction to enable the length thereof to be'varied as desired to vary the angular relation-ship between the crank l2 and the bell crank l4 and thereby to control the amount of is provided on its lower face with a special cam plate or shoe 6' that is adapted to cooperate with -a roller 6 mounted in the main frame to effect,
after a pressing operation, an initial upward movement of the lower die head to cause the body or floor portion 4* to move to a position above the surface of the casing of the die cavity and flush with the upper surface of an anti-friction transfer mechanism or grill hereinafter specified. Such positioning of the lower die head is, of course, necessary to permit the pressedtile to be moved off the die head and out of the die cavity, but the raised position of the die as well as the tile-forming rib thereof forms an obstruction to the conventional movement across the die cavity of the charging and ejecting device. A problem was thus presented as to the ejection-from the die and the subsequent further movement out of the press of this trim form of tile. We solved this problem by dividing up the forwardejecting movement of the charging and ejecting device and provided a dwell intermediate the ends thereof, as hereinabove specified, so as to produce an initial movement synchronized with the movement of the lower die into raised position and at this point we effect a partial ejection only of the tile; then we provide a stop or dwell of said device while the lower die is returning to a position below the die cavity so that the obstruction is removed, and then we provide a secondary forward movement, synchronized With the movement of the lower die into lowered position, by which we operate means to complete the ejecting movement of the tile.
. The capacity of the mold or the quantity of material it can receive is conventionally regulated bythe stop 20 and hand wheels Mil cooperating with screws 20.
Clay is supplied to the hopper or receptacle 1 I and a quantity thereof sufiicient to form a trim tile or number of trim tiles to be produced at each complete operation of the press is periodically transferred from the hopper to the mold casing by a combined ejecting and charging device -2 l. It will be understood that with a given adjustment of the parts of the toggle mechanism, the ultimate travel of the plunger heads toward each other will press a tile of uniform structure, and that the density of the tile may be regulated by the amount of clayv introduced into the die cavity. 7 In accordance with our invention, the combined ejecting and charging device 2! which'has the aforesaid divided forward and continuous rearward movements is operated from a novel cam member 21 mounted on-the power shaft and moves beneath the dust-box hopper 1 to receive its load and thence forwardly in the aforesaid divided movement to partially eject the previously-pressed tile and thereafter to operate a transfer mechanism to complete transfer of said previously-pressed tile and to deliver its said load to the die-cavity. Said combined ejecting and charging "device comprises a carrier or driving section 2| movable forwardly and rearwardly over the table and frame of the die-cavity, and having tion, and a frame located in the opening in the front of the charger; The agitator is carried by and moved longitudinally of the charger as the latter moves rearwardly and forwardly. At the rear of the agitator frame a pair of rod 2 are pivotally connected to rods N and these rods pass beneath the charger and are connected with conventional agitating means arranged at the rearend of the combined ejector and charger.
At its forward end a pivotally connected frame 2| is provided with U-shaped push'er 2i projected from the charger and provided at their forward ends with fenders or push bars Zl of rubber or other oft material to contact with the pressed tile afterit is moved above the die cavity, and to move the completed tile to the transfer device hereinafter more particularly described'for further handling. 1
The'combin'ed ejecting and charging device'Zl is moved from the power shaft 2 by means of the cam member 21 andprovided at each side with a rearwardly extending rod or link 22, the rear ends of which rods are connected by a cross bar 23 and are adapted to be engaged by a pair of arms 24 mounted to rock about a given axis in the frame of the machine and one of which ha at one end an upwardly extending arm 25 which, at its outer end, is provided witha roller 26 cooperating with the said cam 21 on the main power shaft 2. V In accordance with our invention, the cam member 2'! embodies a forward drive-portion 27' embodying an initial forwardly-driving portion 2'! which is adapted to cause the pusher member of the ejecting and charging device to have rapid or quick forward movement over the lower plunger head andto'engage and push a pressed tile over said head and out of the die cavity; a dwell or momentary stop portion il adapted to hold the combined ejecting and charging device substantiallystationary while the lower plunger is above a rearwardly-extending cut-01f plate 21 which is 7 long enough to close the outlet opening to prevent the escape of'material from the hopper 1 during the ejecting and charging movements.
Inconnection with the ejecting and charging device, a dust agitating device is employed, which comprises a rectangular agitating or shaker-boxsection 2| drivenor-moved by said carrier sec the die cavity; and a final forward-drive portion 2'! adapted to cause the ejecting and charging device to have a secondar rapid or quick forward movement to operate the transfer mechanism and to charge the mold or die cavity, and this portionl'l is" connected and communicates with a rearward-drive portion 2'! adapted to cause movement of the ejecting and charging device rearwardly anda'resetting of the transfer mechanism. By the action of this cam member, as the shaft is revolved, the combined ejecting and charging device will have the divided or intermittent forward movement and continuous rear-" ward movement hereinabove specified.
It will be apparent, therefore, that the ejecting and charging device 2| will, in its forward movement, first engage and push a pressed tile a short distance over the edge of the die cavity and onto a transfer mechanism, will then pause or dwell momentarily and stop the pushing movement of the pressed tile to permit the lower die to be moved downwardly out of the path of said ejecting and charging device, whereupon said ejecting and chargin device will then again move' mounted at opposite ends in slides 30 freely movable forwardly and backwardly in grooves 29 formed in the inner side walls and extending the entire length of the guides 23, seated in a depression formed in the bed of the press so as .to be flush with the die plates. The grill is moved forwardly and rearwardly by side rails 3! having at their inner ends pivotal connections at 3! with the forward end of the charging and ejecting device 2! and free forwardly-projecting portions having an operative connection with the grill to enable the forward movement thereof with its load of tile. As illustrated, the side rails 3| are provided with slots 3! a into which pins 23 on the grill .28 extend and also carry spring-pressed latches 32 adapted to engage with the pins 28 'of the grill 218 durin the aforesaid secondary forward movement to move the grill and its load forwardly over and along the bed or die frame of the press to a position adjacent to an olT-bearing belt .33 at which point pins 34 on latches 32 carried by the side rails 3! are engaged by bevelled portions 35 of the latch-releasing blocks 35 causing the latches 32 to be raised and disengaged or released from the grill pins 28 Due to inertia, the grill continues its forward movement in the slots 3 l until the pins 28 are stopped by pins 3 on the blocks 35 whereupon the tile is delivered to the offbearing belt.
Further movement of cam 21 causes the ejecting and charging device 2! to move rearwardly or backwardly to the position shown in Figs. 8 and 9. Durin this movement small lugs 36 at the outer end of the side rails 3| engage outer mem bers of the grill 2.8 and in the further rearward movement of the rails move or return said grill the press in so far as the same relates to movements of the tile-ejecting and transferring mechanism and cooperating parts.
Referring now to Figs. 4 and 5 which show the 7 position of the press in which the tile has been formed, and the top plunger 5 is movin upward and the lower plunger 4 is raised to the ejecting position due to the action of the cam plate 6 engaging roller 6 the cam member 2! has assumed a position in which the ejecting and charging device 2| carrying a pusher 2h has moved back to its loading position. As in the operation of conventional tile presses, the cavit in the shaker box 2 l a .of the ejecting and charging device 2! receives in this position a charge of clay from the hopper I. At this position in the cycle, the grill 28, mounted as aforesaid on slides 33 which are free to move forwardly and backwardly in the guides 29, has not moved from the position said grill assumes during an actual tile-pressing operation. Now, upon movement of the rails forwardly, the latches .32 engage a pin 28 on the grill, and the forward motion of the side rails 3! which carry the spring-pressed latches 32 will thereupon move the grill 28 and the finished tile forward with any further forward motion of the ejecting and charging device 2! and its shaker box 2 l Rotation of cam member 21 will force the roller 25 outwardly from its position in relation to shaft 2 shown in 4 and 5, thus producing a very rapid forward motion of the ejecting and charging device 2! and then owing to the conforma- .tion of the cam at 27 providing the aforesaid momentary dwell, and finally causing it, with the attached forwardly-projecting side rails 31 and the grill 23 to assume the position shown in Figs. 6 and '7 in which the parts are ready for their secondary outward or forward movement along the channel 27. Just prior to this stage, the movement of the shaft 2 has caused pitman 6 and the attached cam plate 6' to move the lower die to its uppermost position and the pusher 2| during its said initial forward movement has pushed the tile off the said lower die onto the grill 23 and has then stopped or dwelled momentarily. Rotation of said shaft 2 also causes said pitman t and cam plate 6' to disengage roller 6 and this action allows the support 3 for the lower die 4 to move downward to the charging Position. The ejecting and charging device will now "move forwardly till the cavity of the shaker box 21* is positioned over the die cavity to deliver a charge of clay for the next pressing operation. During the outer or secondary portion of the forward movement of the side rails 3!, the pins 34 on the latches 32 strike the bevelled latch-releasing blocks 35 causing latches 32 to be raised and thus disengaged from the pins 23 of the grill 28. Due to inertia, the grill continues its forward motion until the pins 28 are stopped by the pins 3 on the latch-releasing blocks 35 in the position shown in Figs. 8 and 9, whereupon, in this position, the tile carried by the grill is delivered to the off-bearing belt B.
Further movement of the cam member 2'! causes the roller 26 to move along the channel 2'! (see Figs. 8 and 9) whereupon the ejecting and charging device 2! will be returned to the position shown in Figs. 4 and 5. During this return movement, the lugs 36 engage the front portion of the grill 28, returning it to the position more particularly shown in Figs. 4, 5 and 10 in which position the slides 39 reach the inner ends of the grooves 23' in the guides 29 in which said slides reciprocate, which terminal of the groove 29f functions as a stop to position the grill at its limit of return or rearward movement. During this return or rearward movement, the bevelled edges of the latches 32 engage and ride over the pins 23 on the grill which thus assumes the position shown in Figs. 4 and 5, ready to engage and push forward the grill 28 on the next ejecting operation.
The operation of the tile-pressing portion of the cycle is conventional and exactly similar to that of conventional presses such as shown, for example, in the Yingling Patent #1268309.
