TILE-MAKING MACHINE.

Specification of Letters Patent.

Patented July 30, 1907.

Application filed M rch 15, 1906. Serial No. 306,235.

To all whom it may concern:

Be it known that I, SAMUEL A. J ONES, a citizen of the United States, residing in Deshler, in the county of Henry and State of Ohio, have invented certain new and useful Improvements in Tile-Making Machines, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to improvements in machines for molding articles made of cement and other plastic materials, and particularly for making tiles for roofs and like structures; and one object of my invention is to provide a machine of this class which shall be simple in construction, cheap in manufacture and efficient in operation.

Another object of my invention is to provide a tilemaking machine by means of which roofing tiles may be made either face up or face down.

A further object of my invention is to provide means for making tiles of special shape.

In the drawings illustrating the principle of my invention and the best mode now known to me of applying that principle, Figure l is a front elevation of my new machine; Fig. 2 is a sectional view on line AA, of Fig. 1; Fig. 3 is a plan 'view of the mold; and Figs. 4, 5, and 6 are all detail views hereinafter referred to. V

The table-bed a is supported by the usual standards b and in turn supports the mold-base 0 formed with four apertures (Z within which reciprocate plungers or pins 6 carried at the ends of the arms f which radiate from a common center g (see Fig. 2) and constitutes a spider. Over the central portion of the mold-base c is placed the false bottom h and around it closely fits the upper mold-body j adjustably mounted upon the three bolts 70 formed with square heads m which project below the table-bed and are adapted to be engaged and turned by means of an ordinary wrench. The upper moldbody 9' is formed with a rearwardly-projecting extension 7 which is supported by a bolt 0 similar to the bolts k; and upon which is adjustably mounted the hingebase 1) secured thereto by bolts q and nuts 1", said bolts extending through slots s formed in the hinge-base p. Integral with the hinge-base or block 10 are formed the hinge-posts or lugs t and the stop-lug it. In the hingelugs t is mounted a hinge-pin 1) fast upon which are the tamping-frame w formed upon its lower surface with the ribs :0, and the rib-forming frame y provided with the slots z adapted to receive the ribs 90 (see Fig. 2). By loosening the nuts r, the hinge-block p may be moved upon the extension n to adjust the frames 10 and y. When the upper plate or the frame 10 is thrown back, its travel is limited by the stop-lug u.

The bolts 70 and 0 pass through the bed a and base 0 and serve not only to adjust the upper mold-body j for different thicknesses of tiles to be made, but they serve in combination with the locking nuts 3 also to secure the upper mold-body j to the mold-base c and the latter to the table-bed a, as will clearly appear from an inspection of Fig. 2. The upper mold-body j is held rigidly in its adjusted position by the upper capstan locking-nuts 3.

Upon the top of the false bottom 71. is placed a thin sheet-metal pallet 4 (Fig. 4) formed with ears 5 having holes 6 for the passage of core-pins 7 which serve to form the nail-holes in the ears of the tile. These corepins are subject to wear at their upper ends by reason of the passing of the straight-edge in smoothing-up the material and striking off the excess. To allow for this wear the core-pins are screwed into the mold-base c (Fig. 5) and by turning them they may be adjusted to the proper height. I

To raise the pallet 4 with its tile still wet and ready to be carried to the drying room, the following mechanism is provided: Fast upon one end of the shaft 8 is an arm 9, while fast upon its other end is a bevel gear 10 which meshes with. the pinion 11 fast upon one end of a shaft 12, the other end of which carries a cam 13 that rubs against the center g from which radiate the arms f carrying the pins or plunger-s e, as above described (see Fig. 2). The travel or swing of the operating arm or handle 9 is limited by the stop-lugs 14, 15 which project from the adjacent standard. When the arm 9 is swung over against the stop-lug 14, the point 13 of the cam or eccentric 13 is brought above the line or aXis of the shaft 12 and forces the plungers e upwardly, thereby carrying the pallet 4 out of the mold into position to be moved with the newly-molded tile to the drying room. The point of the cam is thrown over to a position which prevents the accidental lowering of the arm f and pins e.

Since my new machine is adapted to mold tiles either face up or face down, the corners 16, 17 of the upper mold-body j are both rounded; and the false bottom h may be removed and replaced by another designed and adapted to support the pallet 4 at all points in the making of the tile by the particular process followed. The upper mold-body j is formed on its inner side faces with indentations 20, 21, 22,'and 23, which serve to receive the ears 5 of the pallet 4. When the tile is made face down, the ears 5 fit into the indentations 20, 21 and plugs or filling pieces 24, 25 are inserted in the indentations 22, 23 to prevent the cement from entering therein; while when the tile is made face up, the ears 5 fit into the indentations 22, 23 and the plugs 24, 25 are used to fill in the indentations 20, 21. It will be understood that the core-pins 7 are withdrawn to allow the insertion of the plugs 24, 25 and are passed upwardly through the ears 5 of the pallet 4 in whatever position the latter may be.

By making the tile face down, the operator is enabled to produce a tile having a figured surface or a surface complementary to the face of the pallet shown in Fig. 4. Thus, a tile having its face divided in imitation of tiles of one fourth the size may beiiiade and such tiles when placed in position will add greatly to the appearance of the roof. It is practically impossible to make tiles of the size of the small subdivisions of the tile made face down on my machine and the effect can be obtained only by making the tiles face down. Further, the tile made face down with the subdivisions is a stronger tile by reason of the strengthening effect of the ribs extending across the face of the tile. Another good result following the making of the tile face down lies in the fact that in such a tile the ears Will have the full thickness of the tile, which is not possible in case of a tile made face up, the method heretofore in use. A tile can be made face down in much less time than it takes to make a tile face up, for it is not necessary to smooth off the cement with such care.

In case it is desired to make a tile having one side formed to fit the line of a valley in a hip roof, an inset piece 30, Fig. 6, is placed in the mold in the position indicated by the dotted lines in Fig. 3.
