IMPROVEMENT IN TILE-MACHINES. g

Speciiication forming part of Letters Patent No. 116,480, dated J une 27, 187

To l@all whom it may concern:

Be it known that I, ZENO F. PARUS, of the city and county of Baltimore, in the State of Maryland, have invented certain new and useful -Improvements in Machinery for the Manufacture of Drain-Tiles; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing through letters of reference marked Figure 1 represents a side elevation of a tilemachine with one portion shown in section. Fig. 2 shows a plan and cross-section of the same por- -tion on an enlarged scale.

In the ordinary manner of manufacturing pipetiles the bell-mouth or female end of the pipe has been formed by spinning the plastic tube, or by the attachment of such bell-mouth, separately formed, before-burning. The object of my invention is to manufacture the pipe with a male and female end at one operation and it consists in a novel construction of die, in which the female end of such pipe is formed; furthermore, in a novel construction of the disk or block on which the interior of said end is formed; and in the application of a supportvto such disk or block in such manner as to be unyielding while the bellmouth is being formed, and to drop into a recess in the platform instantly on release of the levers by which it is supported, leaving a level surface for the truck to be run off when the desired lengthof pipe is formed.

Referring to the accompanying drawing, A represents the framing to support the several parts of my apparatus, in the upper part of which the compression-cylinder B is rigidly seated. Within this cylinder is arranged a piston or other suitable device for compacting the clay and forming the pipe as in other pipe-tile machines, said piston being operated by gearing R and screw S, arrangedabove it. Beneath the mouth of the cylinder B a platform, C, is suspended by cords D passing over pulleys e, and counterbalanced by weights f. This platform carries a truck, G, having small wheels h, and on which the pipe, when formed and severed from the clay in the cylinder above, may be conveyed to a convenient position to be removed from the matrix H. The matrix H constitutes the main feature of this invention, inasmuch as in previous attempts to form the bell-mouth or female end of the tube or more parts, constructed in wedge-like form at their connecting lines, in one'or more directions, so that, pn lifting the pipe, said die will, of its own weight, drop from the mouth of said pipe. In combination with the platform C is a disk, l, on the upper end of a vertically-sliding rod, m, which is sustained or supported against the under side of the truck Gr by the levers n and o, the

irst of which is provided with a counterbalanceweight, p, by which it is removed from under the rod m when the latter is released from the toe q of the lever o, and, on release of the said rod, the disk l, at its upper end, falls into a corresponding recess in the upper side of the platform C, forming a level surface, and thence descends with said plarform during the formation of the pipe.

From the above description it will be seen that when all the parts are arranged in the position shown in Fig. l, and the cylinder below the piston is lled with tempered clay or other plastic material of which the pipe 4or drain-tile is to be formed, the lever o is to be held in the position shown, to support the dies H and 'i against the mouth of the cylinder until the cavity between said dies is lled with the plastic material from the cylinder B by the pressure of the piston or other equivalent device thereon, which is indicated by the oozing of such material through one or more small Oriiices near the lower edge ofthe die i, at which time the lever o should be released, when the platform C, truck G, and die H i will, under a continuance of the pressure on the clay exuding through the annular space around the core-block T, be caused to descend until a pipe of the desired length has been formed, when said pipe is to be severed at the bottom of the cylinder in the usual manner, and the truck G which carries it may run off the platform; after the sectional dies i have been removed the pipe may be lifted between tongs or holders of suitable contour, when the die H, from its sectional wedgeshaped construction, will become separated from N EEIOE.

' it, and the pipe is'ready to be placed in the kiln for the purpose speciiied.

2. The die H, made to connect with the coreplug T and matrix i, and made in three or more parts, of Wedge-shape in both length and depth,

so that they Will freely separate from the pipe when the latter is lifted from the supportingtable, as set forth. l

3. The disk l, fitting into a recess in the platforni C, in combination with its rod mand levers fn and o, for operation, essentially as described.
