TILE-MOLD.

Specification of Letters Patent.

Patented May 17, 1910.

Application filed July 27, 1909. Serial No. 509,831.

To all whom it may concern: l

Be it known that I, FREDERICK GORMAN, a citizen of the United States, residing at Okemah, in the county of Okfuskee and State of Oklahoma, have invented a new and useful Tile-Mold, of which the following is a specification.

It is the object of the present invent-ion to provide an improved construction of mold, and the invention relates more specifically to that class of molds which are designed for use in molding drain tiles and the like, and one aim of the invention is to provide a mold of this type so constructed as to mold each tile with a flange at one end and a rabbet at the other end, whereby the tiles may be fitted end to end in a water-tight manner.

It is a further object of the present invention to provide a mold construction of such character that the mold sections may be readily assembled and disassembled without danger of injuring or defacing the tile being molded.

Other novel features of the invention and structural details embodying advantages will be pointed out and understood from the specific description which is to follow.

In the accompanying drawings Figure 1 is a vertical sectional view through a mold constructed in accordance with the present invention. Fig. 2 is a detail perspective view of the outer wall of the mold, the sections thereof being shown in assembled relation. Fig. 3 is a similar view of the base of the mold. Fig. 4 is a perspective view of one of the sections of the outer wall of the mold. Fig. 5 is a view similar to Fig. 2, illustrating the core of the mold, the sections thereof being in assembled relation. Fig. 6 is a perspective view in detail of the head of the mold upon which the core is assembled. Fig. 7 is a perspective view in detail of one of the sections of the core of the mold. Fig. 8 is a perspective view of one of the bands for disposal about the core of the mold. Fig. 9 is a similar view of the strip which is disposed against the mold core and closes the space between those sections of the core between which the wedge blocks are inserted.

In the drawings the mold is illustrated as set upon a base, which is indicated by the numeral 10, and is supported upon sills 11. The base 10 is formed centrally with an opening indicated by the numeral 12, and, upon its upper surface is further formed or provided with an upstanding flange 13, which is continuous, and may be annular, rectangular, or of other outline.

It will be observed, from an inspection of Fig. 3 of the drawings, that the opening 12 in the base 10 of the mold is concentric with respect to the flange 13, and the function of this construction will presently be fully eX- plained.

It will be understood of course that by assembling the several sections comprising the mold wall, about the upstanding annular flange 13, upon the upper surface of the base 10, the sections are not only held in proper relative position, but also in centered relation and against lateral slipping or sliding.

The mold proper embodies in its structure an outer wall and a core, and this outer wall is made up of a number of sections, each of which is indicated by the numeral 14. Each of these sections 14 is preferably comprised of a number of staves, which are secured together in arcuate relation, and the several sections, when assembled, form a cylindrical mold wall, as will be appreciated from an inspection of Fig. 2 of the drawings.

It will be understood that while the mold sections are herein shown and `described as of arcuate form, and the completed mold wall as of cylindrical form, these sections may have other forms, or, in other words, the mold wall may be rectangular, if desired, depending, of course, upon the form of title it is desired to manufacture.

In setting up the mold, the sections 14 are assembled u on the base about the flange 13 thereon, an when properly assembled, hoops 15 are fitted over the assembled sections, and circumscribe the walls at the upper and lower ends thereof, these hoops being clearly shown in Fig. 2 of the drawings, and one of the hoops being shown in perspective directly above this figure, as if about to be disposed or iitted upon the assembled sections.

The mold proper further embodies a core, which is disposed within the mold wall, or, rather, is surrounded by it, and between which and the said wall the cement or other material from which the tiles are to be molded, is poured. This core is illustrated in Fig. 5 of the drawings, and, like the mold wall, is built up of a number of assembled sections, and each of these sections is indicated by the reference numeral 16, the sections being substantially identical with the sections 14 of the mold wall, except that they are of smaller dimensions.

In assembling the sections 16 of the core of the mold, they are disposed edge to edge, as in the case oif the sections 1/-1 of the mold wall, and are held in such relation through the medium ot' a band 17, fitted upon the core at the lower end thereof, and a band 18, fitted upon the core at the upper end thereof, this latter band carrying an outstanding flange 19, of substantially the same thickness as the flange 13, but of smaller diameter.

In order that the sections of the core may be held expanded to the full extent, there are fitted between the opposing edges ot two of the sections 1G of the core, one at the upper and the other at the lower end thereof, wedges, indicated by the numeral 20, these wedges being driven into place after the bands 17 and 13 have been disposed upon the core. Inasmuch as the insertion of these wedge blocks between the opposing edges of the sections as above described will serve to space the said edges, a sheet metal plate or strip 21 is provided, which is disposed against the outer surface of the core and is engaged at its ends by the bands 17 and 1S, whereby it is held firmly in place in position to close the space between the said edges. T his band is clearly shown in perspective in Fig. 9 of the drawings.

In order that the core may be held in centered relation with respect to the wall ot' the mold when the mold is set up and in condition to be filled, there is provided a head 22, which is circular in outline and is fitted in the opening 12 in the base 10 of the mold, this head having an upstanding enlargement 23 upon its upper face, which also is concentric with respect to the opening 12. This upstanding enlargement 23 upon the head 22 is or the same diameter as the interior diameter of the core of the mold, and, as will be readily understood, the mold core sections are built or assembled around this enlargement and upon that portion of the upper face of the head 22 which lies beyond the peripheral edge of the enlargement. In order to support the head 22 in position in the opening 12, there is provided a cleat 24, which is slidably and removably mounted upon the under side of the base 10, as clearly shown in Figs. 1 and 3 of the drawings, it

being understood that, by moving this cleat, the head normally supported thereby will drop through the opening 12, to permit of collapse of the core, or rather oit' the sections thereof.

In using the mold, the core sections are first assembled upon the head 22 and about the enlargement 23 thereon, and the wall sections are then assembled upon the base l0 about the upstanding iiange 13 thereon. After this has been done, the plastic material from which the tiles are to be manufactured is poured into the space between the outer surface of the core and the inner surface of the wall and is allowed to set and harden. After the material has become sufficiently hard to permit of dismounting of the mold, the wall sections are first removed from around the tile, after which the cleat 24 is removed, allowing the head 22 to drop beneath the base, whereupon the wedges 2O are driven out from between the opposing edges of the sections comprising the core, and the core sections are collapsed and removed.

lVhat is claimed is In a mold, a base havingan upstanding annular fiange, a plurality of mold sections assembled about said flange, said base being formed also with an opening concentric with respect to the flange, a head fitted in said opening and having a circular upstanding enlargement, a plurality of mold core sections assembled upon said head about the enlargement thereon, wedge blocks inserted between certain of said sections whereby to expand the same in assembled relation, means fitting about the sections for holding the same in such relation, said sections, at their upper ends, being provided with an outstanding annular flange, a. strip iitted against the sections and closing the space between those sections between which the wedge blocks are inserted, and means reniovably supported beneath the base for supporting the head within the opening.

In testimony that I claim the foregoing as my own, I have hereto aifixed my signature in the presence of two witnesses.

FREDERICK GGRMAN.
