PATENT orFlc EDMUND W. ZEH, F NEWARK, NEW JERSEY.

POWER TILE PRESS.

Application filed October 23, 1920. Serial No. 418,891.

To all whom it may concern Be it known that I, EDMUND V. ZEH, a citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented new and useful Improvements in PowerTile Presses, of which the following is aspecification.

Ihis invention relates more especially to tile presses in which an upper die cooperates with a lower die comprising a central portion anda frame around said central portion -movable independently thereof, said frame forming with the central portion of the diea receptacle for-the material to be pressed into tile. i

The objects of the invention are to provide a powertile press embodying novel features of construction which ,will produce tile of superior quality and with a minimum expenditure of time and labor; to provide novel and improved means for reciprocating the frame as the tile is being pressed; to provide improved means; for automatically locking said frame of the lower die as it is depressed by the upper die. so as to hold it down; to provide such means which will operate continuously as the frame is depressed by successive steps; to utilize cams for such'loz-king means; to operate said cams automatically: to lock the cams against operation when the frame is elevated, and to release them by the initial downward movement of the frame; to secure means for causing the upper die to impart to the tile a second blow without rising up out of the frame; to provide supplemental means for.

finally depressing the frame to release the tile; to restore the frame to its upper position automatically and by springs as soon as it is unlocked from its depressed position; to provide adjustable stop means to deter ITLine the upper position of the frame and also its lowest position flush with the central portion of the lower'die'to discharge atile; to provide a tile press of the character described embodying a minimum number of simple moving parts which will withstand the wear and action of the dust incident to the manufacture of tile, andto obtain other results and advantages as may be brought out in the following description.

Referring to theacoompanying drawings,

in which like numerals of reference indicate the same parts throughout the several views,

Figure 1 is a front elevation of a tile press" Figure 3 is a fragmentary view of the lower portion of the press, the lower die and bed of the press being shown in section, and the upper die being shown compressing a tile in the lower die;

Figure 4 is a transverse vertical sectional view taken on the line 44;of Fig. 3;

Figure 5 is a horizontal sectional view taken on the line 55 of Fig. 1, thelower die, its frame and the bed of the press being shown in plan view .Figure 6 is a transverse vertical sectional view through the lower part of the press showing the manner of forcing the frame of the lower die. downwardly into a position flush with the top of the central portion of said die, and

Figure 7 is a similar view showing the manner of loading'the lower die with the material. of which the tile are formed.

In the specific embodiment of the invention shown in the drawings, 1 indicates the bed of a press of my improved construction, supported upon suitable legs 2. Upon said bed are spaced uprights 3, 3 between which slides a cross-head 4 carrying the upper die 5. The lower die comprises a central portion 6 fixed upon the bed 1 of the press, and a frame 7 surrounding said central portion and fitting slidably thereon to move up and down. I have shown dies adapted to make one square tile at a time, but it will be understood by those skilled in the art that the shape and number of tiles made at a time are immaterial. I

The frame 7 is fixed, as by nuts 8, 9, upon the upper ends of supporting rods, 10, 10,

whichtextend slidably downward through spaced guideways at the top and bottom of t e bed 1 and extend somewhat belowsaid bedy Normally the frame is held in its uppermost position b

helical springs

11, 11,

one on each of the re s 10 resting at its lower end on a bearing plate 12 secured to the bottom of the bedl and pressing at its upper end against a washer 13 underlying a stop,

such as pin 14, on the rod 10 below the top of the hollow bed. Said springs thus tend always to force the frame upward, and its uppermost position is determined by suitable stops, those which I have shown and prefer to

use comprising bolts

15, 15 on opposite sides of each of the supporting rods 10, said bolts being fast in the top of the bed 1 and projecting up through a plate 16 secured to the frame and provided each with a head 17 above said plate. As shown, the plates 16 are on the supporting rods 10, between the frame and one of its clamping nuts 8 and 9, preferably the lower one, and each plate is parallel to the adjacent side of the frame so that its ends project beyond the car 18 of the frame which takes the supporting.

rod, to receive the

bolts

15, 15, see Figures 4 and 5. Said bolts screw into the bed 1, so that they are adjustable in height to determine the uppermost position of the frame as desired, lock nuts 19 being provided on said bolts to make them fast when adjusted. It

will be understood that the uppermost position of the frame is such that it extends above the central fixed portion 6 of the lower die, so as to form therewith a mold or chamber for the dust or material to be compressed into tile, as shown in Figure 2.

When the upper die 5 descends it first enters the frame 7 enough to seal the top of the said mold or chamber formed thereby with the central fixed portion 6, and then further downward movement of said upper die is transmitted to the frame so as to carry that down also as the dust or materialds compressed into a tile. the parts being at the end of the stroke in the positions shown in Figure'3. For thus moving the frame down- Ward, I provide at the underside of the cross head 1, on opposite sides of the die 5, depending projections 20. 20 of sufficient length to engage the frame 7 and move it as described; preferably, said projections are in the form of bolts, screwed into the base 21 of the upper die and provided with lock nuts 21 so that they are adjustable to vary "the time of their engagement with the frame as related to the time the upper die enters said frame and thus vary the seal above referred to. 7

When the upper die is raised, aftercompression of the'tile is completed, it is neces sary that the frame 7 retain its position, without elevation by the

springs

11, 11, or be locked against moving upward, and I accomplish this, automatically. by the following means. Beneath the bed 1 and in line with the depending ends of the

frame supporting rods

10, 10, (one of them being apertured for the purpose, see Figures 3 and 4), is a horizontal shaft 22, mounted in

bearings

23, 23 depending from the bearing plate 12 and a bearing 24 in one of the legs 2, so as to project at the side of the press. This shaft 22- has fast upon itself wedging

cams

25, 25, one adjacent each of the depending supporting

rods

10, 10 and having a shoulder 26 overlying a roller 27 laterally projecting from the end of the rod, see Figures 3, 4 and 6. Each shoulder has at one end'a pocket 28 in which the roller 27 of its adjacent supporting rod is caught when the frame is normally elevated by its

springs

11, 11, and the end of the cam shaft 22 which projects at the side of the press has a lever 29 with a Weight 30 which tends to turn the cams so that the pockets'28 leave the rollers 27 and eccentric portions 31 of the shoulders 26 engage said rollers. Thus when the frame 7 is forced down by the upper die as it forms the tile, as described above, the said eccentric portions 31, which are of increasing radial distance, wedgingly engage the rollers and hold the frame down when the upper die is raised. It will also be noted that this locking action takes place automatically, by virtue of the weight 30.

After the upper die is raised, upon completion of the compression ,of the dust or material into a tile, it is necessary to further depress the frame 7 the thickness of the tile, or until the top of the frame is flush with the top of the central portion 6 upon which the tile lies, inorder to discharge said tile, and this I do by the power of the press through the introduction of some supplemental means between the upper die and the frame 7 so that the pressure is transmitted to said frame without the pressed tile receiving any. As an illustration of such' means, I have shown a loading box 32. containing dust or material to fill the lower die resting upon a shelf 33 on the front of the frame 7, see Figures 2, 5, 6 and 7 the sides of this loading box. at its end next the press, being provided with arms 34, 3t which lie at their free ends upon the sides of the frame 7, as shown in Figures 2 and 5. The operator, when he is ready to finally depress the frame to discharge the tile. pushes the loading box 32 toward the press enough to cause the ends of the

arms

34, 34 to underlie the

bolts

20, 20 on the upper die. and then upon again bringing down said upper die the frame 7 will be further depressed by said bolts striking said arm ends resting upon the frame, as shown in Figure 6. Of course the ends of the. arms must be thick enough so that the upper die will not touch the tile at this time. and as the frame lowers the cams 25 automatically look it'down there. so the upper die can be raised at once. This final position of the frame 7 is preferably determined by adjustabl stops, which I have shown as bolts 35, projecting from the top of the bed 1, into which they screw, and provided with

lock nuts

36, 36. 1

tion of the lower die, and bothfiush with the. shelf 33, the operator slides forward the loadingbox 32 until it registers with the central portion of the die, as shown in Figure 7, the front end of said box pushing the com pressed tile onto a conveyor 37 which carries it off, said" conveyor being also flush with the top of the frame, central portion and shelf. Then the operator raises the weighted lever 29, and allows the

springs

11, 11 to automatically elevate the frame 7 to its normal position, the rollers 27 entering the cam pockets 28 so that the frame is locked in such elevated normal position and the cams are idle. This upward movement of the frame 7 carries the loadingbox with it and the dust or material in said box drops through its mesh bottom and fills the mold or chamber of the lower die formed by the elevated frame with the fixed central portion. The loading box is then withdrawn onto the shelf .33 again, and the press is ready to operate to compress another tile in the same manner as has been described.

The upper die 5 of my improved tile press can be reciprocatedby, any suitable means adapted tocause said upper die to strike percutient blows upon the material in the lower die, although I have shown the cross head 4 which carries it secured to the screw 38 of a percussion screw press of a suitable and well-known type adapted to be operated by power. It has been found that two blows upon the dust or material being formed into a tile are desirable to properly compress the same and expel the air, and, as the upper die must not be withdrawn from the frame of the lower die for the second blow, I have provided means by which the said screw 38 can move independently of the upper die and far enough to withdraw upwardly after the'firstblow and descendupon the upper die with a second blow. Referring to Figure 2 it will be seen that I have provided the screw 38 'with an enlarged head 39 whichlies in a cylindrical socket 40 iinthe cross.

head 4 and is held against withdrawal bya keeper plate 41, forming a swivel connection. The head 39 thus has a limited movement independent of the cross head. and for the second blow the screw is withdrawn for not more than this limited distance and then brought down again against the bottom of the socket 40. This enables a second blow to be struck without breaking the, seal formed by the upper die with the frame 7,

and yet said upper die can be moved up and down with respectwto the lower die, when desired, as usual.

While I have shown and described one pos- I sible embodiment of my invention, it will be understood that this is for the purpose of illustrating the principles thereof only, and

I I L it will be-obvious that many modifications and changes can be made inthe detail construction of my press and its various parts bythose skilled in the art without departing from the spirit or scope of the invention.
