APPARATUS FOR MAKING TILE.

Application filed April 26, 1926. Serial No. 104,567.

My invention relates to method and apparatus for making tile. It has to be primarily with method andl apparatus for the making of tile from concrete, which tile is suitable for use in floors, hearths and mantels.

Tile of this kind is usually made from clay and is an expensive production. In the first place, only certain kinds of clay are suitabley for making tile and the manufacturer quite frequently yhas to have his clay shipped to him in a crude state from a distant point with a` consequent addition of high freight rates to the .cost of the finished product. Furthermore, after thefclay is received, it must then be graded, mixed and treated before it is used.

After the clay has been molded, it vmust then be cured and burned. Great loss is occasioned to the manufacturer from the burning process because of the fact that there is a variable warpage and shrinkage during such burning. Likewise, such tiles should be of exact dimensions and a great many tiles are worthless because they are not of proper dimensions, while t-he variation which is permissible in practice results in an increased labor cost in the setting of the tile to hide the deficiencies.

I have devised a method which makes possible the production of tile from concrete and of exact dimensions with smooth, cleancut edges. In devising this method, I have produced a novel type of apparatus which, while permitting the production of tile of exact dimensions, also permits of the production of different sized tiles on the same apparatus by means of an extremely simple adjustment. My method is such that I am able to produce concrete tile without the use 4 of applied pressure.

Another phase of my invention consistsv making apparatus with one corner of the top framework cut away to 'show` the mold, f

pallet and pallet-supporting block in detail. Figure 2 'is a vertical section taken through the upper part of the structure shown in Figure 1.

As will be seen from the drawings my tile making machine consists of a main frame 1, havingtop flanged cross-bars as at 2. conn'ectedV at their ends to legs 3. In the drawing these cross-bars 2 are cut away at one corner to show the interior ,mold structure. The legs 3 are braced on two sides ofv the frame hy diagonal brace members 21 while 4f and 5 indicate longitudinal cross-hars con- 'nect'ed at their ends to the-legs 3.

A shaft 6 is shown journaled at its ends in the cross-bars 4 and 5 and provided at one end with a crank handle 7. A stop 22 is provided to limitthe rocking of said crank handle 7 and to hold the pallets elevated when the machine is in a discharge position. mounted on the shaft 6 are over-center cams 8 and 9 which support and operate upon a rigidly built vertically movable frame having horizontal bars 10fand 11. This frame is also provided with upright bars 13 which are in turn connected at their upper ends to horizontal bars 14 and hracingrods 15.

Resting upon and secured to said bars 14 is a square plate 16. Thisy plate 16 has a series of holes drilled therein so that pallet supporting blocks 17 can be fastened thereto by means of bolts or screws or in any other manner.

It will be apparent that this structure produces a rectangularframe work of unusual rigidity and Ihave found that this contributes materially to the maintenance of straight-edges for the tile during the rais# ing of the tile from their molds preliminary to removal and curlng.

Supported by a iiange on and fastened tov said bars 2 So as to be easily removable therefrom is a mold box 18 having openings of a suitable shape therein. These molds have removable bottoms or pallets 19 resting upon the pallet supporting blocks 17.

However the number, size and shape of these molds maybe changed as desired by merely unfasteningxthe mold boxes in the machine and substitut-lng mold frames of Fil the size and shape desired. rllhe thickness oi' the tile to be 'formed may be regulated by the thickness of the pallet supporting block used. lt a shallow mold block is used the tile will be thick While if a deep mold block is used the tile Will be thin. The depth ot the mold may also, be regulated by adjustment ot the set scre\v'20 against the crank handle, thus limiting the downward movement ot the trame 11 and mold bottoms consisting of the blocks 17 and pallets 19, resting upon the plates. Either or both ot these means may be used tor regulating the depth of the mold or thickness o1'l the tile to be 'formed therein.I The size and shape of the pallets and pallet supporting blocks used, preferably conform to t-he size and shape of the mold used or the tile to be formed.

in operation, the rectangular trame-Work in lowered position with the handle 7 on the cam shaft supported upon the set screvv 20. The cement mixture is then placer in the molds and smoothed oli' level with the top ot such molds by means of a trovvel. lilhen this operation is completed, the handle is swung to the right with the result that the rectangular frame-Work is elevated by the cams and the higher portions of these cams passes over their centers until they assume a position in Which the handle is stopped 'from further movement to the right ot Figure 1 by a pin 22 and the trame-Work is maintained in elevated position.

ln elevated position the pallets Which support the tiles are above the level of the molds and these pallets with the tiles thereon are set aside for the curing operation. After curing, the tiles are removed from the pallets by giving each a slight tap.

lt will thus be seen that I have invented a machine for making concrete tile andthe liketha-t is simple in construction but very efficient in operation. lVith this machine perfect tile with clear cut edges can be turned out with great speed, and at a greatly reduced cost over the clay tile. One of the great advantages of this machine is that tile of any size, shape or thickness may be made by simply changing the mold trame7 pallets and pallet supportingl` blocks, the machine being so constructed that these changes may be made with a minimum amount ot time and eiiort.

'lhe plates which l use may be made ot dilierent materials. l have found that I can produce tiles with smooth hard surfaces very effectively by using glass plates or by using aluminum, brass or copper pallets suitably bullied. l can also use steel or iron plates or pallets.

l have also discovered that a superior tile can be made by first inserting a layer of one material into the mold and then placing another layer ot' a dilierent mixture on top ot the lirst layer.

r1 still further important feature of my invention arises from the tact that I am able to produce an unusually beautiful product by introducing, with the cement, colored glass, micasparcrystals, or granite oi' ditierent colors. These elements may be introduced throughout the entire tile or only in the surface layer, that is, the layer lirst placed in the mold or troiveled in from the top side.
