WALTER JOHNSON, 0F CLIO, MICHIGAN.

CEMENT-TILE MACHINE.

Specification of Letters Patent.

Application filed July 28, 1909.

Patented Aug. 23, 1910.

Serial No. 510,064.

T 0 all whom it may concern:

Be it known that I, IVALTER JOHNSON, a citizen of the United States, residing at Clio, in the county of Genesee and State of Michigan, have invented certain new and useful Improvements in Cement-Tile Machines, of which the following is a specification.

This invention relates to certain new and useful improvements in cement tile machines.

The objectof my invention is to provide a tile manufacturing machine constructed so that drain tiles of various diameters may be molded upon one machine.

Another object is to provide a tile making machine, so constructed that the cooperating mechanism will simultaneously actuate the hopper or mixing tray carrying the cement and the plunging core.

A further object of my invention is to provide a tile machine with a hopper so held that the same may be intermittently brought into and out of engagement with the mold.

Another object of my invention is to so carry a pipe core that in withdrawing the same a superficial finish will be imparted to the interior of the pipe. And finally, I aim to provide a drain tile making machine in which a rocking mortar or mixing tray is held operable in combination with the plunging core, so that the mortar mixture is, at each operation of the plunger, carried from or toward the tampingorifice.

\Vith these and other objects in view, the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, and particularly pointed out in the appended claims, it being 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 forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a front view of a tile making machine embodying my invention,

showing the tray lowered and'the bowl in working position, Fig. 2 is a side view of Fig. 1, Fig. 3 is a top View, Fig. 4 shows the mixing tray in its raised position, the machine being shown in side view, Fig. 5 is a section on the line 33 of Fig. 3, Fig. 6 is a detail sectional view of the connections between the plunger rod and the rock lever, Fig. 7 is a detail sectional view of mold, Fig. 8 is a detached detail of the tray collar.

In the manufacture of cement tile, it is quite essential that the cement is introduced into the mold properly mixed, and that the mixture is prevented from settling before being molded. It is further quite important that the core should be withdrawn in such a manner that the soft plastic tiles will not be dragged or distorted inward upon the excursion of the plunger. These desirable objects I employ in my invention, and in the drawings, the numeral 10, 10 represents the front standards of the supporting frame as used in my invention. In connection with these front standards 10 I use the rear standards 11, these standards being connected by means of the cross bars 13 and strengthened by means of the transversely held brace bars 12.

The rear bars 11 are connected below by means of the brace 15, and near the upper end by means of the brace bar 14. In front the frame is secured by means of the horizontally held brace board 18 which is supported upon two of the brace members 13, and held above this brace board 18, is the pallet 19 which serves as a guide to the plunger as used in my invention.

Secured to the upper rear brace member 14 by means of the hinges 20, is the mixing tray 22 having the border battens 8, this tray being provided with a suitable opening arranged to receive the tamping plate 26, having the inwardly directed collar 25 held within the tray opening. This tamping plate 26 is secured to the tray 22 by means of the screws 28.

Held to the pallet 19, .is the collar 30 which surrounds the plunger opening within this pallet, this collar 30 being secured by means of the screw cars 31. It will be noted that this collar does not entirely encircle the plunger opening.

The base board 18 is provided with a centrally disposed opening 43 which registers with the plunger opening within the pallet 19, and this opening 43 is spanned by means of the plate 42 which has an ear 43'.

Secured to the rear lower brace member 15, are the cleats 16 which carry the pin 6 and this pin in turn pivotally supports the rock lever 4, which projects beyond the forward portion of the standard, as shown. At its forward end, this rock lever 4 carries the pin 5 and this pin in turn pivotally carries the coupling head 3. This coupling head as shown is made up of two similar sections connected by means of the screw 9 and has a semicircular socket within which is held the semispherical head 2 within which is held the lower end of the plunger 41, this plunger being secured by means of the pin 1. The plunger 41, as shown, is provided with a spiral groove 9, and the lip 43 of the plate 42 is arranged to be held within this plunger groove.

Secured to the upper end of this spirally grooved plunger 41, is the collar 37, and this collar 37 carries the plate 35, while intermediate of its ends this spirally grooved plunger further carries the circular head 36 and carried by these two

members

35 and 36 is the cylindrical core 34 which is of sheet or any other suitable metal. This core 34 is "arranged to snugly reciprocate within the opening 27 of the pallet 19 as shown.

In its normal position, the tray 22 is supported upon the upper ends of the standards 10 and 11 and the uppermost positioned cross members 13. Extending from this tray 22, is the lever 22 and extending from this lever 22 to the rock lever 4 is the connecting rod 4, the instrumentalities being so arranged that when the tray 22 is held in a horizontal position upon the standards 10, the rock lever 4 will be in an upward position so that the upper end of the plunger 34 will be flush with the upper face of the tray as shown. In this position of the plunger 34, the plunger at its upper end is contained within the tray collar 25 from which it is held however, in spaced relation while being snugly held within the guide opening 27 of the pallet 19.

hen the instrumentalities have been properly arranged and the mixing tray is in a horizontal position, the operator in order to use the machine would depress the rock lever 4. This would result in the plunger 34 being carried downward in a manner to impart a circular movement to the plunger by virtue of the spiral groove 9 within the plunger contacting wit-h the lip 43. In its lowermost position, the plunger 34 contacts with the base bar 18, while its upper end rests flush with the upper end of the pallet 19. The outer mold or jacket 45 would be next secured to the machine. This mold or jacket is in the form of a sheet metal plate, constructed to form an open seam tube. Then the edges of this jacket 45 are connected, the jacket will be of such a diameter as to be snugly held within the collar 30 this collar holding the jacket or mold 45 to the pallet 19. In order to hold this open scam in a closed condition, I provide the same with the pins 46 to support the hooks 47 there being a number of these used being arranged to engage the lugs 48. For the sake of convenience, these hooks 47 are provided with operating handles 49. The upper end of this jacket 45 will then be arranged to be snugly held within the tray collar 25 when this tray is lowered.

A suitable cement or concrete mixture is then placed upon the tray 22, when the operator releases his foot 4 permitting the weight of the cement and tray to carry the tray downward and at the same time project the core into the jacket. In the downward movement of the tray 22, the cement upon the tray would naturally gravitate toward the tamping opening 24. The operator would then proceed to carry the cement into the mold and firmly tamp the same about the core 34. The mold having been properly filled, the operator would finally smooth 0d the top of the tile, and then depress the lever 4 which would result in the tray again being carried upward, at which operation the cement mixture would gravitate toward the rear of the tray, thereby causing a mixture of the same, while the core would be carried out of the jacket with a circular movement to impart a superficial finish to the interior of the tile, while at the same time preventing the tile being in any way drawn inward so that the true cylindrical and symmetrical shape of the plastic tile is preserved.

The tray 22 having been carried to its extreme upward position, the mold would be readily accessible and could be easily removed from within the supporting collar 30. The newly finished tile would then be carried to a proper drying shelf when the open seam mold would be released in operating thle hooks 47 and removed from the finished ti e.

From the foregoing it will be seen that at each upward and downward movement of the plunger, the cement or concrete upon the tray is carried toward the tamping opening or away therefrom insuring the cement or concrete being agitated at each movement of the plunger to preserve the same in a properly mixed condition.

Vhile I have described the plunger as being provided with a spiral groove to impart a rotary movement to the plunger, it should be understood that the plunger may be reciprocated without imparting a rotary movement.

In order to insure the plunger rod 41 being held in a vertical position, I provide the coupling head 3 and the yoke 21 with the intervening link 19 secured by means of the pins 9. The yoke 21 is secured to the rock lever 4 by means of the pin 5.

The device is portable, simple of construction and is readily operated and any desired size of tile may be made in substituting the proper core and mold. The upper end of the plunger rod 41 screws into the collar 37 so that when it is desired to change the mold it is simply necessary to unscrew the same. So also, when the diameter of a tile is changed, a new supporting collar 80 is employed as is also a properly sized tray collar.

Having thus described my said invention, what I claim as new and desire to secure by United States Letters Patent is:
