Specification of Letters Patent. Patented Aug. 15, 1911.

Application filed January 3, 1911. Serial No. 600,456.

To all whom it may concern:

Be it known that I, AREND WICHERTJES, a citizen of the United States, and residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Tile-Machines, of which the following is a complete specification.

The main objects of this invention are to provide an improved tile machine of great efficiency; to provide a tile machine in which the molds may be quickly filled with tile material and having means for accurately measuring the material before delivering it to the molds; to provide a tile machine having packing or compressing mechanism associated therewith by means of which the material in the molds may be pressed to the desired form; to provide a tile machine adapted to give the freshly made tiles a waterproof or coloring coat before their removal from the molds; to provide a tile machine having mechanism adapted to sever the adjacent tiles while in the molds and provide clean cut edges therefor; and to provide an improved mechanism for removing the completed tiles from the molds.

A specific construction embodied in said invention is illustrated in the accompanying drawings, in which:

Figure 1 is a fragmentary, vertical section of a tile machine embodied in this invention, with parts in elevation and showing one mold carriage in section at the tile discharging end of the machine, and one mold carriage in side elevation at the compressing end of the machine, and the compressing mechanism in section. Fig.2 is a fragmentary top plan View of the main frame, the track and the carriage at the discharging end of the machine, and with the mold filling and compressing mechanisms removed, and with the supporting frames for the cutting and filling mechanisms in horizontal section. Fig. 3 is an end elevation of one of the knives. Fig. 4 is an enlarged section taken on line 44 of Fig. 1 with parts removed. Fig. 5 is a transverse section taken through the measuring device and transfer truck, and looking toward the discharge end of the machine, with the glazing tank removed. Fig. 6 is a section taken on line 6-6 of Fig. 1, with parts removed. Fig. 7 is a transverse section of the mold carriage with the partitions removed and with the bottom mold plates elevated to discharge the tile. Fig. 8 is a rear end elelongit-udinal,

vation of one of the mold carriages with parts removed. Fig. 9 is a transverse section of one of the mold carriages. Fig. 10 is a section taken on line 10-10 of Fig. 1. Fig. 11 is an enlarged detailof the locking means for the partitions. Fig. 12 is a fragmentary section of one of the carriages and the cutting means for severing the tiles, and showing the cutting means in elevated position in dotted lines.

In the construction shown, a frame 1 is provided upon which the tile forming mechanism is mounted, and for convenience of description the end 2 of the frame will be referred to as the discharging end of the frame and the end 3 as the packing end of the frame.

Extending longitudinally of the frame along one side thereof is a main track 4 which is interrupted near the center of the frame by a transfer track 5 which extends transversely of the frame and below the level of the main track 4. Mounted to run on the transfer track 5 is the transfer truck 6, on which are two tracks 7 and 8, which eX- tend longitudinally of the frame 1 on the same level as the track 4, and are adapted to be brought into register or alinement with said track 4.

Mounted on the frame 1 at the rear of the track 4 and above the carriage 6 is the measuring and filling hopper 9 which is supported on the frame 1 by means of a sheet metal frame 10. The hopper is open at its bottom and the bottom margins 11 thereof are curved to form the arc of a circle, as shown more clearly in Fig. 5, and a shaft 12 is journaled longitudinally of the hopper between said margins 11. Rigidly mounted on the shaft 12 and adapted to revolve between the margins 11 is the measuring cylinder 13, which is open on one side the full length thereof to receive the material from the hopper 9 when the opening is up. The walls of the measuring cylinder 13 are braced by stays 14 radiating from the shaft 12. At one end of the shaft 12, on

the outer side of the frame 10, is a crank 15 by means of which the cylinder may be rotated in the direction of the arrow shown in Fig. 5 to dump the contents of the cylinder. A deflecting plate 16 is hinged in the forward portion of the hopper in position to overlap the joint between the cylinder andthe hopper and when the hopper is rotated .to dumping position it tilts the bottom of the plate inwardly so that it may bear on the outer surface of the cylinder, and when the cylinder is returned to normal position said plate scrapes off the adhering material on the outer surface of the cylinder.

The tiles are formed in molds in the mold carriages 17 and 18 which are mounted to travel on the tracks 4, 7 and 8. Preferably two carriages are used simultaneously, though three may be employed if desired. Each of said carriages 17 and 18 comprises a box frame having trucks or wheels 19 thereon adapted to travel on said tracks, and the ends of the carriage are of less height than the sides, as shown more clearly in Figs. 7, 8 and 10. In the upper portion of the box frame are a plurality of vertically movable mold plates 20 which are formed on their upper surfaces to conform to one surface of the tile to be formed. Said mold plates 20 are supported upon the upper ends of the rods 21, which are supported at their lower ends on vertically movable bars 22 which are slidably mounted in the box frame. The rods 21 pass through a floor or guide plate 23 which is secured to the side walls of the carriage at a point sufiiciently below the top of the carriage to permit the plates 20 to rest thereon when at their lowest limit of movement. Coiled springs 24 are carried on the rods 21 and bear at their upper ends against the plate 23 and at their lower ends against the bars 22. At the end of the carriage adjacent to the discharge end of the frame 1 is journaled a stud shaft 25 which is slightly to one side of the center of the carriage and which has an angular outer end. On said stud shaft 25 is a sprocket wheel 26 which is in alinement with a sprocket wheel 27 on a stud shaft 28 journaled at the bottom of the carriage directly below the shaft 25. A sprocket chain 29 is carried on said sprocket wheels, and a shaft 30 extends longitudinally of the carriage and is journaled in the bars 22 centrally between their ends. The ends of the carriage are provided with vertical slots 31 through which the shaft projects.

On the end of the shaft 30 adjacent to the sprocket wheels 26 and 27, and slightly out of alinement therewith, is a sprocket wheel 32 which is also engaged by one lap of the chain 29. On each end of the carriage and adjacent to the slot 31 is rigidly secured a vertical rack 33 in which mesh gears 34 which are rigidly secured on the shaft 30. hen the stud shaft 25 is rotated the sprocket chain 29 causes the shaft 30'to rotate and the gears 34 travel up or down the racks 33, and the shaft 30 thereby moves the bars 22 vertically which in turn move the mold plates 20. At the discharge end of the machine is a crank 35 having a socket adapted to receive the angular end of the stud shaft 25 when the carriage is at that end of the frame 1. The crank is adapted to operate the mechanisms for raising and lowering the mold plates 20.

At the ends of the mold plates 20 and separating the same from eacli other and from the ends of the carriage are the mold partitions 36 which are slidably mounted in grooves in the side walls of the carriage. Said partitions are shaped at their upper ends to conform to the upper surfaces of the tiles and they ex-.

tend downwardly'through the floonor guide plate 23 and are provided'at their lower edges with laterally turned flanges 37. Rods 38 are mounted at their upper ends in the guide plate 23 and at theirlower ends in transverse beams 39 supported on the sides of the carriage. A bufier 40 is carried on the upper end of each rod 38 immediately below the plate 23 and acts to limit the upward movement of the partitions. Springs 41 are carried on the rods 38 and bear at their upper ends against the flanges 37, and at their lower ends against the beams '39. Extending longitudinally of the carriage beneath the partitions 36 and rigidly secured to the flanges 37 is a lockingbar 42 which projects at its ends through slots 43 in the ends of the carriage. The ends of the looking bar are provided with notches or teeth 44 and pivoted on the end walls above said ends are the pawls 45 which are adapted to engage said notches with their lower ends, and between their upper ends and the end walls of the carriage are springs 46 which act to force the upper ends of the pawls outwardly and hold the lower ends thereof in engagement with the notches. For the purpose of throwing the pawls 45 out of engagement with the notches 44, each pawl is provided with an arm 46 which'extends below the bar 42, and a lever 47 is pivoted on a rod 48 extending transversely of the carriage beneath the bar 42, and pivoted to said lever are push rods 49 which extend through the end walls of the carriage and bear against the arms 46. When said lever is turned in one direction it forces the push rods 49 outwardly, thereby forcing the arms 46 outwardly and carrying the pawls out of contact with the ends of the bar 42.

After the material has been placed in one of the mold carriages from the hopper 9, the carriage is moved to the packing end 3 of the frame 1 where the material is pressed into shape. For the purpose of compressing the material a tilting frame 50 is pivoted at one end to the end 3 of the frame 1. Said tilting frame lies between the track rails 4 and normally on a level therewith. Journaled in the frame 1 beneath the free end of a tilting frame is a shaft 51 on which are cams 52 adapted to bear on the under side of the frame 50. On one end of the shaft 51 is a crank 53 by means of which the shaft may be rotated to cause the cams 52 to tilt the frame 50, and thereby tilt the carriage, as shown at 18 in Fig. 1.

The frame 1 is provided at the end 3 with side members 54 which extend above the top of the carriage and are provided in their inner faces, near the tops thereof, with longitudinal grooves 55. Slidably mounted in said grooves 55 is a wedge member 56, having its thick end directed toward the end 3 of the frame 1. The upper surface of the member 56 is parallel with the tracks 4 while the under surface inclines downwardly toward the end 3. Said wedge member 56 is provided with longitudinally extending, centrally disposed slots 57 and 58, the upper edges of which are built up at 59 so'that they are parallel with the lower edges, or in other words, they incline downwardly toward the end 3 of the frame 1, so that each slot is of the same depth throughout its length.

Mounted'on the underside of the wedge member 56 is the upper mold plate 60 which is provided in its upper surface with grooves 61 adapted to receive tongues 62 on the wedge member, as shown more clearly in- Fig. 10. The tongues 62 and grooves 61 act to hold the plate 60 in proper relation to the member 56. Arms 63 and 64 project upwardly from the plate 60 through the slot- s 57 and 58 respectively. The arm 63 is provided with gears 65 which are journaled on a shaft 66 in the arm, and are adapted to travel on cogs at the sides of the slot 57. Pawls 67 are pivoted on the arm and are adapted to engage the gears 65 and lock the plate 60 to the wedge member during the backward movement of said member toward the end 3 of the frame, so that the plate will be pulled longitudinally off from the tiles with the wedge member after the compressing operation. The arm 64 is provided with rollers 65 which travel on the wedge member at the sides of the slot 58. For the purpose of operating the wedge member 56 a screw shaft 69 has threaded engagement in a cross bar 70 carried on the ends of the side members 54 which are adjacent to the end 3 of the frame 1. The inner end of said shaft is rotatively connected in the end of the wedge member and is adapted to move the wedge member longitudinally. The bar 70 serves to brace the side members 54 at one end, and at their other end is a tie rod 71.

The mold plate 60 is of a width to fit between the side walls of the carriage, and is formed on its under side to conform to the upper surface of the tile and the upper edges of the partitions 36. Said plate 60 is provided at its end adjacent to the end 3 of the frame 1 with a down-turned flange 72 which engages over the end of the carriage, as shown in Fig. 1, and prevents the plate from slipping on the carriage when the wedge member'56 is being advanced.

After the tiles have been sufiiciently packed or pressed the carriage is lowered back onto the track 4 and is moved toward the end 2 of the frame 1 to the position which the car 17 occupies in Fig. 1. As the carriage approaches the limitof its movement in that direction the tiles may be given a coating of waterproofing or coloring'material from a tank 73 which is supported over the track 4 by means of a supporting frame 74 on the end 2 of the frame 1, and at the rear of the track 4. The tank 73 is provided with a slide bottom 75, below which is a measuring compartment 76 which is adjustably secured on the lower portion of the tank by bolts 77 passing through slots in the measuring compartment. The compartment 76 is provided with an outlet 78 in its bottom which is controlled bya slide 79. A knife or wiper 80 is adjustably supported on a bracket 81 suspended from the hopper, and its lower edge is shaped to conform to the upper surface of the tiles. Said knife is. adjusted so that as the carriage passes beneath it, it will wipe or scrape off from the tiles any excess of coloring or waterproofing material.

A shaft 82 extends longitudinally of the frame 74 at the rear thereof, and slightly above the top of the carriage. Journaled on said shaft is a plurality of arms 83 which are spaced the same distance apart as the partitions 36, and are adapted to extend forwardly directly above said partitions when the carriage is at the limit of its movement toward the end 2 of the frame 1. The outer ends of said arms 83 are rigidly connected together by means of a bar 84, and on the under side of each arm, at its outer end, is a knife 85 which extends slightly below the under surface of the arm and the edge of which is of the same shape as the upper edge of the partitions 36. On the outer end of one of the arms 83 is a spring hook 86 adapted to engage in a notch or recess 87 in the front side of the carriage when the knives are down, and hold the knives from rising. Secured on the frame 74 above the outer ends of the arms is a hook 88 adapted to hold the knives up out of contact with the partitions, so that the carriage may clear the knives when it is being moved on the track 4.

The operation of the construction shown is as follows: The mold carriage is run onto the track 8 of the transfer truck 6 and the truck is moved rearwardly to bring the carriage beneath the measuring hopper 9 where the desired quantity of material is emptied into the mold by means of the cylinder 13. The truck 6 is then run forwardly to bring the carriage into alinement with the track 4. The carriage is then run to the side of the carriage. The downward movement of the plate 60, which rests on the partitions 36, moves the partitions downwardly against the action of the-springs 41. The partitions carry the locking bar 42 downwardly and the pawls 45 engage the notches in the ends of the bar and prevent the partitions from returning upwardly. After the material has been compressed the carriage is lowered back to the track 4 and is moved toward the opposite end of the frame 1. As the carriage passes beneath the tank 7 3 coloring or waterproofing material may be placed on the tiles if desired. As the carriage reaches the limit of its movement toward the end 2 of the frame 1, the end of the stud shaft 25 enters the socket in the crank 35. The knife arms 83 are then lowered to bring the knives down onto the partitions and sever any material which may overlap the partitions. The hook 86 holds the arms down while the tiles are being elevated from the carriage. The crank 35 is then operated to cause the shaft 30 to travel upwardly in the slots 31 thereby carrying the mold plates 20 up out of the carriage against the tension of the springs 24,

as shown in Fig. 7. The tiles may then be removed from the plates 20 and the plates are returned to normal position by the springs 24 or by the aid of the crank 85. The lever 47 is then operated to release the pawls 45 from the locking bar 42, and the partitions return to normal position by the action of their springs. The carriage may then be returned to the transfer truck 6 to be again filled.

By means of the truck 6 which brings the carriage out of alinement with the track 4 when being filled, it is possible to use two or three carriages on the machine at the same time.

While I have shown and described but one specific embodiment of my invention, it will be understood that many details of the construction shown may be varied or omitted without departing from the scope of the claims.
