R NNER TILE.

Original application filed April 21, 1921, Serial-No. 463,160. Divided and. this application filed July 13, I

1923. Serial No. 651,242. e I

To all whom it may concern: v

Be it known that I, RAY G. CoA'rns, a

citizen of the United States, residing in which in substantially all'cases were unitary structures with openings running therethrough. Unitary structure tiles usually represent a larger integral mass of tile which is liable to crack or break when in use and also which does not lend itself easily to heating up due to the relatively large mass and due to the fact that the interior cavities are usually heated at a different rate from the exterior of the tile.

The present invention overcomes the difficulties of the known art by providing a runner tile formed in sections in such manner thateach section carries a part of the runner tile opening and'thatthe sections themselves, relatively speaking, are flat tilelike members. Furthermore, the opening through the tile is preferably formed in such'manner that when the sections of the tile are assembled the completed opening is oval in cross section so that the gate may be easily broken after the ingot is frozen. Preferably also the tile is wedge-shaped and is arranged to set in the mold body in such manner as to lift out when the ingot is stripped from the mold. This facilitates re-use of the runner tile, because the sections of the tile fall away from the gate without the necessity of 'breaking the tile to remove it from the ingot.

, In view ofthe foregoing-it may be stated that the principal object of the invention is to provide a runner tile for metallurgical use which tile is formed in two sections in such manner as to easily be stripped from themetal forming the root in the runner tile when the metal solidifies.

A still further object of the present invention is a runner tile provided with an oval runner conduit whereby the necessary cross sectional area of the'runner conduit may be obtained in a tilewhich is relatively thin and narrow.

A still further and more specific objectof the present invention is a runner tile of the character specified wherein sand grooves are provided on the sides of the runner tile to form a sandbelt around the runner tile to stop leakage and. at the same time'prevent formation of fins around the tile from metal in the matrix of the mold.

Other and further objects of the present invention will in part be obvious and will in part be pointed out hereinafter in the specificationfollowing by reference to the accompanying drawings, wherein like parts are represented by like characters throughout the several figures thereof.

Realizing that the present invention may be embodied in constructions other than those herein specifically disclosed, it is desired that the present, disclosure shall be considered as illustrative and not in the limiting sense.

Figure 1 is a view of a moldwith the parts thereof separated to show one. form of construction in which the runner tile comprising the present invention maybe utilized.

Figure 2 is a front the runner tile. Figure "3 is a side elevation of the runner tile. 1Figure'41, is a back View of the runner t1 e. Y Y Figures 5 and 6 illustrate the runner tile separated in order to show. the formation of the runner conduit.

Figure 7 is a top View of the runner tile. Figure 8 is a base view of the runner tile. Figure 9 is a perspective view of a modified form of the invention.

Referring nowto the drawings, the mold elevational view of will only be referred to in a general way Number 463,160, filed April 21,1921, of

which the present application is a division. Referring therefore to the mold in a general way it is preferably formed of sec-' tions, the lower one comprising a stool 1 provided with a head closing member 2. The body of the mold comprises an inverted trough member 4 and the fountain 5 of the mold is adapted to set upon .and cooperate with the end of the body portion A and with the head closing member 2. Preferably the head closing member 2 in the present embodiment is provided with a wedge-shaped opening into which the runner tile structure is adapted to fit.

The runner tile is formed of

sections

6 and 7 which may be easily and cheaply formed by dies in suitable presses.

Shallow grooves

8 and 9 are formed in the contiguous faces of thesections so that the desired runner channel 10 is formed when the parts are assembled. The plane of separation of the parts of the tile preferably is along the vertical longitudinal plane of the ingot, which passes through the major cross-sectional axis of the runner channel. It will be noted that when the sections are assembled the cross-sectional boundary of therunner tile channel is oval in shape with sharp angular corners adjacent the plane of separation of the two parts. This gives greater clearance and allows each half of the tile to be readily separated from the solidified runner or gate which is left in the tile after casting. This construction permits stripping the tile without breaking so that it may be used over again until it becomes unfit for use. I

Preferably one section is provided with a groove 11 and the other section is provided with a tongue 12 which is adapted to fit into the groove and to position the parts in such manner as to properly form the runner opening 10'. The sides of each section are recessed as at 14, to provide sand grooves which meet beneath the runner tile. Preferably a smaller sand groove 15 is provided in the back of the tile as well as at the side. The front of the tile is cut away as at 16 to provide a vent opening for. the mold gases. The tile illustrated in Figures 1 to 8 illustrates a tile tapering downward, whereas the tile illustrated in Figure 9 shows a modified form of the tile tapering backward. I

In setting thetile, a thick clay wash may be brushed on the tile in a narrow strip on portions where the tile contacts with the walls of the recess, then after the tile has been set a loose fine dry refractory sand, may be run into the sand grooves and between the tile and its respective recesses in which it sets. This fine material will readily penetrate around the tile while the clay wash will prevent leakage of the sand into the mold.

It is evident that these sand groove eonstructionsincrease the clearance space between the tile and the tile cavity so that the tile is quickly relieved of pressure when the ingot is stripped, and facilitates setting the tile after the mold has been set up because considerable clearance permits of easily manipulating the parts of the original setup.

Having thus described my invention, what I claim is:
