To all 107mm it may] concern .f
Be it known that I, FRANK Hamilton, Butler county, State of `Ollio,
have invented certain new and useful Im# provements in Tile-Presses, of which the fol-` lowing is `a specification. i
The present invention relates to improvements in tile presses and particularly to a means for supplying the material to be pressed to the mold dies, andmaintaining` such dies clean so that the tile produced` thereby will be smooth, without pit marks or defects caused by the clay adhering toieither the top or bottom dies. f
ln the accompanying drawings the iinproveniente are shown `as applied to a press of the form described and illustrated in a` prior application ilediMay 9, 1914, Slerial No. 837,536, of which application thepresent case is a division. Thepresent improve-l ments, however, are of course notfliniited in i their use to a press of the particular con struction illustrated,
In the accompanying drawings,`
Figure l is a side elevation of a tilepress embodying the present invention;
Fig. 2 is a sectional View of a portionA of the press, the means for supplying clay to the dies being shown diagrammatically only;
Fig. 3 is a plan view of a portioniof the l machine, being substantially a section on the line 3-3 of Fig. l;
Fig. 4 is an elevation partly in section of the parts shown in F ig. w y y Referring to the drawings, and particularly to Figs. -1 and 2, the press `comprises a main supporting frame A, a main power shaft B mounted in` bearings in said `frame, a mold box or casing C, a lower plunger or die D, an upper, toggle actuated plunger or die E, a pitnian F connecting the die toggle with a crank on theshaft B, a clay reservoir or hopper G and a reciprocating mold charging. device adapted to be reciprocated by cain mechanism actuated by the shaft B to convey a charge from the hopper to the mold casing.'
The support H for the lower die Dis carried by slides I fitted in suitable guide ways' ontl'ie frame A; and the shaft K constitut ing the pivotal support for the upper inember of the toggle by Which the die E is `carried is mounted in bearings in said slides `IL The shaft K is of eccentric form in cross speicationor Letters Patent.
Yiwuraise,a` citizen of the United States, and resident of thisiapplicatioii filed October 4 Patented July `1, 191,1),
section relative to the endbearing portions and to one 'end thereof issuitably secured a crank M which isconneoted by a rod mavith l one arm cfa bell crank `mounted Ourthe"` .frame of the machine `and havin@ its other end provided with `a roller m with each rotation: of the shaftll.` As shown in 6o Lwhioha a y cam M? on the power shaft B cooperates, whereby the eccentric, toggle supporting, p shaft K will be rocked in its bearings during Fig.` 1, the connecting` rodm is of such con-` y l struction that the length thereofimay be i varied as desired to control the relativeintensity of the two pressures obtained during a i each rotation `iof the main shaft A. i
The pitinan F is provided on its lower f face with a cam plate F` that is adapted to` cooperate with a roller F2 mounted inthe.
main frame to effect simultaneous verticali` movement of both ofthe dies,for ejecting the tile from the mold. `The capacity `of the mold, or the quantity of the material it` can receive is regulated by a stop S, and v wheels 'S2 and screws S. An eccentric bushing T is interposed between the eccentric portion of the shaft K and the upper member to forma tile or number of tiles to be produced at each completev operation of the ma` chine is periodically transferred from the `of the toggle..`wliich surrounds such eccenf: tric portion of ,theshafu so that the relation: of the shaft and toggle may be varied to` hopper to the mold casing by a reciproeat` ing charging device N. Itwill be understood that with a given adjustment of the parts ofE the toggle inechairiisin` the ultimate travel of the die plates toward each other is the same, thus producing tile of uniform thickness; but the density is `regulated by the amount of clay in the mold. The charging device comprises a rectangular shaped frame and a rearwardly extending plate or cut off member Np', which prevents escape of material from the hopper when the tubular section of `the charging `device is outfof alinement with the opening in the bottom of said hop-per. The charging device is pro-` vided at each side with a rearwardly eXtending rod or link n, the rearends of which,`
` l l rods are connected by a cross bar it and are adaptedto be engaged by apair ofarmsnzylio: i
mounted to rock about a common axis in the frame of the machine and one of which has at one end an upwardly extending arm n3 which at its outer end is provided with a 5 roller n4 coperating with a cam N4 on the main p ower shaft B.` j
The charging device is provided with an agitator by means of which the charge of finely divided clay is deposited in the mold in an yeven uniform condition. As shown in Fig. "3, the chamberor charge receiving space is divided into avplurality of compartments by transverse partitions a5 and in each yof'said compartments is arranged a Wire or small. rod as. The several wires a6 are connected by rods a7 which are adapted to reciprocate in suitable guides inthe front andrear walls of the charge receiving ocket of the device N. The rear ends o these rods fn? are connected by suitable links or bars with a crank shaft O3 to which is attached apinion o. Shaft O3 is mounted in suitable bearings on the charging device and pinion o is adapted to engage with a gear .O, mounted on a shaft O4 in bearings on the main frame, when the pocket of the charging device is positioned above the mold casing. The gear O is constantly rotated by a sprocket O and a chain connecting it with a sprocket O2 on the countershaft b geared to the shaft. B. l
At the forward end of the charging device there is arranged a brush P. This brush is mounted in bearings on the forwardly eX- tendingarms of a pair of bell crank levers at opposite sides of the charging device and the other arms of which levers are, by eX- tensible rods p, connected with the charging device shifting rods n. As shown in Y Figs. 3 and 4L, the forward ends of the rods n are provided withpins or connected to a cross bar kmounted in slots in the side walls of the'charging device, so that said rods are adapted to have a slight'forward movement independent of any movement of the said charging device. Thiss movement is sufficient toactuate the bell crank supports for the brush P and rock the latter downwardly into position to contact with the upper surface of the lower plunger or die D, as it is carried thereover by the actuation of the arms a2.' The rods p, bein adjustably connected with the bell cran s and actuating means7 permits of the necessary adjustment to compensate for wear of the brush and cause it to properly bear upon the surface of the die to effectually clean it. The brush shaft is provided witha'snitable pinion that engages a rack P supported by a stationary stud orflug Pf2 risino from the frame ofthe machine sothat thebrush will be rotated as itis moved over the die. As the return movement of the charging device begins, the bellcrank supports for the brush P will be i rocked to lift the brush abcve the plane of the upper surface of the mold box or casing and the charge of clay that has been deposited on the lower die therein.
By the construction and arrangement of parts illustrated herein the charge of clay within the mold box or casing is subjected to two distinct compressing actions by a single rotation of the main power shaft, the second of said compressing actions being materially stronger or heavier than the first. During the interval between said successive compressions the charge is relieved from pressure of the dies so that the air entrapped in the mold may freely escape.
In Fig. 2 the parts areshown in the posi- S0 tions occupied at the completion of a pressing operation with the lower die raised to the top of the mold box or casing and the upper die separated therefrom so that the finished tile may be pushed from the lower die onto a suitable table or conveyer. The charging device N is provided in advance of the rotary brush P with an ejector p and as the shaft B turns in the direction indicated by the arrow in Fig. 2 the cam there- 90 on will actuate the charging device to force the completed tile from the lower die and carry a suitable c harge of clay over the lower die in the mold box or casing. During such movement of the charging device the brush P will, as before described, be caused to clean the upper surface of the die D and during the latter part of such movement the pinion 0 will be in mesh with the gear O so that the agitating means in the charging device will be operated. It will be seen that the stroke of the charging device is of such length that at the forward limit thereof a portion of the charge receptacle is beyond the front wall of the mold box or easing. This is important as it avoids any possibility of the clay being undesirably caked or compacted in one portion of the mold box more than another, during the return moven'xent of the charging device.
While the brush P will maintain the lower die relatively clean, yet it is at times desirable to wash the faces of both the lower and upper dies; and as in the normal operation of the machine the charging device is be- I tween the dies whenever they are sufficiently separated, means have been provided whereby the charging device may be disconnected from the power shaft and caused to remain stationary beneath the hopper G during a rotation of said shaft. The means for effecting this adjustment are shown particularly in Figs. 3 and t. The rods a by which the charging device is reciprocated, are not permanently connected to the arms n2 but 125 preferably each of said rods n is provided' with a U-shaped section or recess into which a stud at the lower end of the adjacent arm n2 is adapted'to extend. By means of a leverVW-the rods n may be lifted from engageiiiientY with said arms a2, thereby disconnecting the charging device and power shaft and `means are provided whereby the parts will be held thus disengaged during a complete rotation ofthe shaft. The handle W is mounted on a rock shaft which is provided with two rearwardly extending downwardly curved arms w `adapted to respectively cooperate with rollers mounted at the ends of the rods a. Therefore it will be seen that if the handleWis depressed the arms w will positively lift the rods a from engagement with the crank arms n2 and permit said crank arms to swing forward without imparting any movementto the chargingdevice. A spring pressed stop X acts to hold the rods n in said elevated disconnected position and a curved guard w13 on each ofj the rods n coperates with the adjacent roller at the lower end of the crank. armati to prevent rengagement of said crank and rod a until on the completion of the movement of the crank arm the parts are returned to relative position shown in Fig. 4. It is ofcourse essential that means be provided to permit i mold casing, a lower diewithin said casing,
an upper die movable into` and from the casing, a charging device, means for moving j the charging deviceto and from a position above the mold casing, a reciproca-tory agitatorwithin ,i the charging device, `a con stantly running gear, `and means for autoinatically connecting said gear and agitator to actuate the latter when the charging `device is positioned to discharge its contents;
