IMPROVEMENT IN TILE-MACHINES.

Specification forming part of Lettcrs Patent No. l52,890, dated July 7, 1674; application filed January 12, 1874.

To all whom it may concern Be it known that I, J ULrUs WHITEHEAD, of Darwen, in the county of La-ncaster and Kingdom ofEn gl and ,re-cl'ay-works mana-ger,

\ have invented certain improvements in machinery or apparatus to be employed in the molding of sanitary tubes or pipes, of which the following is a specification:

This invention relates to improvements in the dies or apparatus for forming or molding the sockets of sanitary tubes or pipes, and in the apparatus for operating such machinery, whereby the frequent damage to the sockets of the tubes or pipes during the process of molding is obvia-ted.

lVhen making a number of pipes at one operation, I affix the dies, constructed as herein after described, to the bottom of the claycylinder. hen making pipes of large diameter, one at a time, I construct the clay-cylinder with its lower end shaped according to the form of socket required. At each side of the said cylinder is a guide-rod. Extending' from rod to rod, and immediately under the claycylinder, is a table or bed rail on which the soeket-blocks rest. rlhe table or bed rail ascends the guide-rods by means of chains or cords and counterbalanceweights passed over pulleys. The socket-blocks are thus brought into proper position within the socketed end of the clay-cylinder, and there held by catches until the piston descends, partially forcing the clay into the socket-dies. 4The steam is now shut oft' and the catches are released. rI he steam being again turned on, the piston resumes its downward stroke, forcing down the table or cross-rail to its original position, and completing the formation of the cylindrical part of the tube or pipe. The completed tubes or pipes are now removed from the table or bed rail, (the boards 011 which the socketblocks rest are hinged so as to facilitate re moval of the pipes by tilting them onto a bearing-board hereinafter described,) and the socket-blocks withdrawn from the sockets of the pipes and replaced on t-he table or bedrail ready to repeat the operation.

The die of each socket is perforated and its interior lined with cloth, through which air is admitted on the farther descent of the piston, so as to prevent formation of vacuum.

The following is a full and complete specication of this invention, reference being had tothe live sheets of drawings accompanying the same.

Figure l is afront elevation ofa machine for molding nine sanitary pipes or tubes at one operation, and constructed according to this my invention. Fig. 2 is a side elevation of the same. Fig. 3 is a section, showing interior of the dies, drawn to an enlarged scale. Fig. el is a plan view of the table or cross-rail and the socket-blocks, and it will be seen that the dies are constructed of complete rings, and not in halves or part rings, as heretofore. Fig. 5 is a detached die and socket, enlarged scale. Figs. 6 and 7 are elevation and plan of a bearer. f

A is the clay-cylinder, which is of the ordinary character, the clay therein being forced or expelled therethrough and into the dies thereof by a piston and piston rod or rods, as usual. B are the socket-molds, which are secured to the lower part of the Claycylinder. The beveled part B1 forms the shoulder of the socket. rIhis part, by preference, I make of wood, and it is secured between the parts B2 and B3 by the bolts B4. F F are holes formed in the part B1. (See Figs. 3 and 5.) From the holes F F branch or radiate other smaller holes F F. The object of these perforations is to admit atmospheric air to the socket-dies when a pipe or pipes are being forced from the cylinder and molds, and so prevent damage to the pipes or tubes by the formation of a vacuum or vaeuity between the socket-shout der of the pipe or tube and the interior of the die. The perforated face of the part B3 is faced or covered with cloth, linen, or other fabric, lV, to prevent the clay being forced into and stoppin g up the holes F', and so preclndin g the admittance of the necessary snpply of air. On each side of the clay-cylinder A is a guide-rod, H, and extending from rod to rod is a table or' bed-rail, J, on which the ordinary socket-block K rests. The table or bed-rail J ascends the guide-rods by means of the counterbalance-weights and pulleys K2 K2. The socket-blocks K' are thus brought into proper position within the socket-formin g end of the clay-cylinder, (see Fi g. 2,) and there held by the catches L catching and holding thc flanges of the nuts M. rlhe nuts M may readily be adjusted to any height on the guiderods H by lneans Ot' the chasing or screwing` thereon. The clay-piston. now partially descends within the clay-cylinder, forcing` the cla-y into the socket-dies, and so forming` the socketed end of the pipes or tubes. The catches L are now released from the angcs of the nuts M by hand or foot lever connected at their junction N, and the clay-piston resumes its downward stroke, forcing` down the table or bed-rail J, and forming the cylindriA cal part l of the tube Or pipe.

Any convenient number ot' such dies may be employed, according1 to the power of the clay-piston and capacity of theclay-cylinder, the cores Rl being suspended by the bridges t2, as will be clearly understood.

The perforated portions otl the dies are arranged between the plates B2 and B3, and the whole secured to the bell or bottom ot' the clay-cylinder by bolts. rlhe bed'rail J will of course be provided with a corresponding number ot' socket-blocks, K, as shown at Fig. 4. The boards T, On which the socketblocks rest, are hinged, in Order to facilitate removal by tilt-ing the pipes S when molded Onto the bearer S, on which they are carried or removed to the drying-room. The socket-blocks K will be greased or oiled as usual.

Having1 thus fully described the nature and particulars of this lny said invention, together with the manner in which the saine is to be or may be performed or carried into practical operation, I 'would have it distinctly understood that I claim as my inventionl. The catches L and adjustable nuts M onl the guide-rods, as and for the purpose herein fully described and shown.

2. rlhe combination, with a clay-cylinder, A, of dies or molds B, constructed Of complete annular portions B1 B2 B3, the part Bl being' beveled to form the shoulder of a pipe Or tube, having holes or passages F F radiating,` therefrom, and a surface of linen or other retieulate fabric, WT, all constructed and operating substantially as and for the purpose specilicd.

5. The boards T, hinged for the purpose herein described, and the bearer S', as described and shown.
