TILE FORMING MOLD Filed sept. '14, 1944 ,may
) Inventor tlorneys Patented July 30, 1946 UNITED STATES PATENT OFFICE 1 Claim. 1
The present invention relates to new and useful improvements in tile forming molds for making sewer tile.
An important object of the present invention is to provide a tar paper lining for the mold and which forms a cover for the completed tile which facilitates the stripping of the mold from the tile after the latter is set and in which the tar paper cover or jacket for the tile serves to pre* vent vegetation and tree roots from growing through tile when the latter is laid, thus serving to protect the tile from injury commonly caused by such Vegetation and tree roots.
A further important object of the present in- Vention is to provide a mold of this character and which, through the use of the tar paper jacket or lining in the mold permits the removal of the mold after the tile has become set and prior to the complete hardenings thereof, whereby a relatively small number of molds are required in the quantity production of the tile.
A still further object of the invention is to provide a mold of this character of simple and practical construction, which is efficient and reliable in performance, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.
Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawing forming part hereof, wherein like numerals refer to like parts throughout, and in which:
Figure 1 is a side elevational view of the mold.
Figure 2 is a longitudinal sectional View thereof, showing the tile formed therein.
Figure 3 is a sectional View taken substantially on a line 3-3 of Figure 1.
Referring to the drawing in detail, according to my invention, a longitudinally split cylindrical mold 23 is provided adjacent its ends with a pair of diametrically split channel guide bands 23 thereon for receiving driving pulley of a mold rotating machine, not shown, of a type suitable for rotating the mold to form the tile therein under the action of centrifugal force.
The sections of the mold are secured in assembled relation by means of a pair of clamping bands 24 Operated into clamping position by means of a lever 25 pivoted to the ends of the clamping bands. Each section of the mold is also provided with guide tongues 26 overlapping the adjacent edge of the respective section to guide the latter into assembled relation with respect to each other.
A tar paper lining 32 is secured to the inside of the assembled mold sections, the lining being continuously formed.
To the inside of each mold section, at one end thereof, is a tapered ring segment 33 While the opposite end of the mold is flared as at 34 and formed with inwardly extending tongues 35. Concrete in a plastic state is placed in the mold 23 and through the centrifugal action caused by the rotation of the mold will cause the tile 3S to be formed on the inside thereof. The end of the mold provided with the ring 33 is closed by a sectional end plate 33a.
The tapered ring member 33 on the inside of the mold section will form an externally tapered portion 31 at one end of the tile while the iiared portion 36 at the opposite end of the mold will form the bell or flange 38 thereon.
A core 39 is placed in the flared end 34 of the mold and is formed with an annular groove 43 adapted to receive the tongues 35 of the mold to retain the core in position. The core is shaped to form the flared seat 4| in the bell end of the tile as well as the shoulder 42 to accommodate the tapered end and abutment for the end of an adjacent tile when laid in end to end relation.
After the concrete has become set to form the tile the mold 23 is removed and the tar paper lining 32 then forms a jacket or cover for the tile to hold the latter in its proper shape while the same becomes hardened suiilciently for use.
When the tile is laid the tar paper jacket is retained thereon and serves to prevent vegetation and tree roots from injuring the tile and serves.
as a deterrent for the roots working between the connected section of the tile.
The tar paper also functions to aid in the curing of the tile while becoming set as the tar paper prevents quick evaporation of moisture in the tile and with the addition of a suitable curing oil to the inside of the tile utilizes the moisture in the tile for curing. The tile need not be constantly sprayed with water or placed in a curing chamber as now customary, but may be immediately moved to a shed or other storage space for Curing.
It is believed that the details of construction and manner of use of the device will be readily understood from the foregoing without further detailed explanation.
Having thus described the invention, what I claim is:
A tile forming mold comprising a pair of semicylindrical sections, means for clamping the sections in assembled relation, a tapering ring in one end of the sections of the mold, an end plate closing said end of the mold, a flared end at the other end of the mold and having inturned tongues and a core removably inserted in said last-named end of the mold, said core having an annular groove adapted to receive said tongues for retaining the core in position therein, said last-named end and the core forming a bell mouth end on said mold for molding a tile with a bell mouth end.
RICHARD J. KINGSTON.
