ERNEST A. E. LAAGE, or osAKIs, MINNESOTA.

HAND 0R POWER CEMENT-TILE MACHINE.

Application filed November 21, 1910.

To all whom it may concern:

Be it known that I, ERNnsT A. E. LAAGE, a citizen of the United States, residing at Osakis, in the county of Douglas and State of Minnesota, have invented certain new and useful Improvements in Hand or Power Cement-Tile Machines, of which the following is a specification.

This invention relates to cement tile making machines and the principal object of the invention is to provide such a machine which may be operated by power from a suitable motor or other source or by hand.

An import-ant feature of the invention is to provide a novel form of packing means for the cement, whereby it may be quickly and efficiently packed within a suitable casing.

A further objectis to provide such packers or packer of novel form which are adapted to rotate in the operation of packing the cement.

A still further object is to provide novel means in the form of a casing with which said packers are adapted to coact and means for properly positioning the parts of the apparatus as to acquire the greatest amount of work from a minimum amount of power.

Other objects and advantages will be apparent from the following description, and it will be understood that changes in the specific structure shown and described may be made within the scope of the claims without departing from the spirit of the invention.

In the drawings: Figure 1 is a side elevation of my improved tile machine, with the parts in a raised posit-ion, Fig. 2 is a front elevation thereof showing the molding parts in a position when compressing the cement and showing the device for use as a power machine, Fig. 3 is an enlarged elevational view showing the hopper arm and connected parts, Fig. 4 is a top plan View thereof, Fig. 5 is atop plan view of the complete machine, Fig. 6 is an enlarged sectional view of the casing taken on a horizontal line below the hopper and showing the packer shoes in position for packing the cement, Fig. is an enlarged detail view of one of the packer arms and cylinder carrying the same, Fig. 8 is a sectional view of one of the shoes to more clearly illustrate the construction thereof, Fig. 9 is a perspective view of a modified packer arm with the shoe detached, Fig. 10 is an enlarged sectional view of a plunger employed, Fig. 11 is a plan view Specification of Letters Patent.

of the supporting table of the mold casing, Fig. 12 1s a central sectional view thereof on the line 1212, Fig. 13 is a bottom plan view of the table, showing the guard plate carried thereby to prevent wear of the plate through which the plunger is movable.

In the drawings the numeral 1 designates the base of my improved molding machine, said base having slidably mounted therein the plunger rod 2 working inside of the mold 8. Said mold is supported by the cross brace 6 which is held in position above the base 1 by the vertical supports 1. Said supports 4 are connected at their upper ends by braces 5.

To satisfactorily support my improvedmold, and to permit of removal of the mold and tile formed therein together when desired, I secure to the brace or cross piece 6 the plate 8 having a central aperture surmounted by an annulus having a beveled inner face 9 against which fits the beveled edge of the ring 10 secured in position by the keepers 11 pivoted to the annulus. I Resting upon said ring 10 are the mold sections 12 certain of the sections being hinged together while two of the sections have secured thereto the bracket plates 13 having outwardly projecting flanges 14 secured together by the clamp bolts 15 which thus serve to lock the mold together while loosening of the bolts allows the mold to be swung open to facilitate its removal from the tile.

Normally passing upward through the aperture or centerof the ring 10 is the plunger core 16 comprising a tubular shell 18 having the inturned ends 18 providing shoulders against which rest the disks 19 and 19 whose movement into the sections 18 is limited by the flanged ends 18. Said plunger or mold core is made slightly tapering in form in order that it may make a tight joint with the ring when forced upward and may be readily withdrawn from the tile when formed. To enable me to assemble the core and to hold the end disks 19 and 19' in position, I form the disk 19 with an aperture to receive the frustoconical collar 20 while the upper end of the plunger rod 2 is threaded and screws into the disk 19. Screwing of the rod into the disk forces the collar20 against the disk 19 and thus draws the collars toward each other and tightly secures the core tube 18 on the plun- 'er rod. To shift the plunger rod as detoo operating lever 23 which serves to rock the arm 25 and cause said arm to move the link 26 which is pivoted at one end to the end of the rock arm and at the other end to the collar 65 which is secured on the lower portion of the plunger rod 2. This rocking of the lever serves to raise and lower the core 18. To prevent undue wearing of the plate 10 by the plunger, I secure to the under side of the cross piece 6 the plate 21 faced with leather or like material 22 against which the core presses. A resilient keeper 27 secured to one of the braces 4 serves to lock the handle 23 to hold the plunger in position while a shield 64 secured on the plunger rod 2 serves to deflect any material dropping from the mold and prevent said material fro-m clogging the bearing which the plunger rod 2 has in the base 1.

To facilitate ready feeding of material into my mold I secure to the upright 4 and to the supplemental upright 39 rising from the cross piece 6 the bracket arms 35 having the central portion 33 through which passes the pivot 34 having mounted thereon the arm 31 which extends inward and engages the arm 30 projecting from the base 28 of the hopper 17, bolts 32 holding the arm 30 in adjusted position to cause the base 28 to fit down exactly on top of the mold 3, an adjustable abutment 29 aiding in insuring the correct positioning of the hopper. To prevent lateral swinging of the hopper, I secure thereto and to the support 4 a guide rod 67, while to further prevent said swinging I employ the tapering bracket 36 which projects upward through the arm 31. To normally resiliently hold the base 28 against the mold 3, I secure to the base of said bracket a bolt 38 which extends upward through the arm 31, a spring 37 being interposed between the head of the bolt and the arm 31 to force the arm downward.

To enable me to satisfactorily pack the material within the mold 3, I employ the packing arms 51 which are secured to a collar 55 held in adjusted position on the shaft 47 by a clamp screw 56. In the preferred construction of my invention I form in the enlarged bases of lower ends of the arms 51 apertures through which are passed the wedge pin 52 to lock the shoes 50 on the lower ends of the arms. In the modified construction shown in Fig. 9, however, I form the bases of the arms 51 with the dovetailed lugs 53 for engagement in the grooves 54 of the shoes 50 to lock said shoes in position. The shaft 47 is slidably and rotatably supported by bearings secured to cross braces of the frame structure of my molding machine and has on its upper end a cup 57 for receiving weights to force the shaft downward, a collar 58 limiting the clownward movement of the shaft and the angles at which the shoes 50 are secured to the arms 51being such as to cause the shoes and thus the shaft to ride upward on the contents of the mold as the mold is filled and the shaft 47 is rotated.

To readily rotate the shaft 47 I form the same with a squared central portion on which is slidably mounted the miter gear 48 in mesh with the gear 49 carried by the shaft 40 supported by suitable bearings. Said shaft has on its outer end a pulley 41 to receive a drive belt-while intermediately secured on the shaft is a pulley 43 around which passes the belt 42 also passing around i the pulley 44 which is secured on the shaft 45, said shaft being provided with a crank 46 for manually turning the same.

To enable me to readily raise the shaft 47 into position where the packing arms 51 and shoes 50 will be above the mold and hopper, I secure to the uprights 4 the brackets 60 having pivo-tally mounted therebetween-a rock shaft 59 having a shifting yoke 57 formed at its end for engaging the collar 58 while projecting outwardly from the shaft 59 is the arm 59. Said arm is connected by the link 62 with the operating lever 61 which is intermecliately pivoted to one of the uprights 4, shifting of said lever rocking the shaft 65 and thus the'arm 59 and causing the arm to engage the collar 58 and raise the shaft as is shown in Fig. 1, the gear 48 sliding on the squared portion of the shaft. In order that the hopper may be raised above the mold at the sameitime as the packing shoes, I connect the arm 31 and the arm 59 by a rope 63 which serves to draw the hopper upward as the arm 58 is upwardly rocked.

From the foregoing description taken in connection with the accompanying drawings the construction and operation of my improved mold will be readily understood and it will be seen that I have provided an eflicient tile mold in which the plunger may be readily shifted to withdraw the core and in which the otherparts of the mold may be quickly withdrawn .out of engagement with the molded tile and which will consequently facilitate the rapid and easy forming of tiles or like tubular composition pipes.

Having thus described my invention, what I claim is 1. A molding machine including a transverse support, a removable ring secured on the support, a sectional mold resting on the ring, a bracket projecting from the machine, an arm pivoted to the bracket, a hopper adapted to rest on the mold, said hopper having a laterally projecting arm adjustably secured to the said pivoted arm, a second bracket secured to the machine and having a guide lug extending through an aperture in the pivoted arm, a bolt secured to said latter bracket and extending through the arm, a spring mounted on the bolt for forcing the arm downward to resiliently hold the hopper in engagement with the mold, and means for raising the hopper against the force of the spring.

2. Amolding machine comprising a frame structure, a threepart mold casing removably mounted upon a supporting member of the frame, a plate arranged below said casing and having an opening therethrough, a plunger rod slidable vertically therebelow, a detachable hollow plunger secured to the upper end of the rod and movable through said opening a spaced distance from the inner wall of the casing, means for moving the plunger vertically into and out of operative position, a dust panadapted to protect the bearing for the plunger rod below the casing and limiting the movement thereof, a packing shaft rotatably carried by the frame, a cylinder secured to the shaft, arms depending from the cylinder, shoes detachably secured to the lower ends of said arms, and adapted to fit between the casing and plunger and means for exerting downward pressure thereon to compress the material thereunder when said shoes are rotated.

Copies of this 3. A machine of the class described comprising the combination with a supporting structure, and a table mounted thereon and having an opening therethrough; of a ring having an inner annular face provided with a beveled wall, a plate secured therein, a mold casing removably attached upon the ring, a plunger snugly fitting an aperture in the plate for movement into the casing, means below the table and engaging the plunger to prevent excessive wear upon the plate, an arm pivotally mounted upon the frame structure and extending inwardly, an apertured plate having an extension adjustably mounted in the arm, a hopper carried by the plate for movement toward and away from the casing, means for moving the plunger vertically within the casing, and means for packing the material within the channel.

In testimony whereof I affix my signature, in the presence of two witnesses.
