VSpecification of Letters Patent No. 33,055, elated August 13, 18.61.

To all whom it may concern? Be it known that we, LYMAN SMITH, ot North East, in the county of Erie and State of Pennsylvania, and ROBERT FRENCH, of

Keokuk, in the county ot'l Lee and State of Iowa, have invented certain new and useful improvements in Apparatus for Casting Soap or other Substances into Balls, Cakes, or other Forms; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification,in which- Figure l is .a vertical section of the appa-I ratus. Fig. 2 isa plan of the same. j Similar letters of reference indicate corresponding parts in both figures.

rlhis invention. relates lto the employment of a mold `or connected series of molds arranged one above the other, in connection with an elevated Mcistern or other reservoir from which the soap or other substance to be cast is forced in a liquid state into the mold by static or mechanical pressure. j

It consists in the attachment of `the mold or series of molds to the conducting pipe connected with the elevated cistern or other reservoir by mea-ns of a spigot and faucet or other movable joint between which and the mold or series of' molds there is a stop-cock to shut the substance within the mold or molds and retain the pressure therein after the filling thereof, and after the disconnection thereof from the pipe.

To enable others skilled in the art to make and use our invention we will proceed to describe its construction and operation.

The apparat-us represented, is intended for the casting of transparent soap balls. The elevated cistern A, in which the soap is brought to the desired degree of liquidity by the combined influence of heat and the addition of a suitable quantity of alcohol, is incased with a steam-jacket B. The conduct-ing pipe C, by which the soap is con veyed from the cistern A, to the mold, is permanently attached to the bottom of the cistern and is incased to the point where the bend, through which the soap rises to the mold, commences with a steam jacket D, which is in free communication with the jacket B. The steam is admitted to the jacket B, by a pipe a, and the water of condensation is drawn oii from the bottom of the jacket D, by a cock b, or steam trap.

tion turned up in an upright position and has permanently secured to its extremitythe upright spigot c. The pipe C, is fitted at its connection with the cistern with a valve m.

(l, (l, are the molds of which there may be any number consisting of cavities arranged one above the other in a box E, of cast iron, brass or other metal which is divided vertically into two equal parts, which are fitted together with ground faces or otherwise constructed or provided with an air-tight `joint,-are connected by hinges c, whichienable the molds to be opened 'forthe removal `of the `balls or cakes-and are furnished with hooks and staples a, or other means of securing them when closed. The several I molds are connected each with the one above and belowit by a small passage j, by which the soap runs from one to another from the bottom to the top of the series. To the bottom one half of the mold there is permanently attached the `faucet socket g, which is ground Ito -fit air-.tight to the spigot c, and which is fitted with a stop cocklc, to open it to `the VIlowest mold d; and to the -top of the same hal-f, is permanently attached' the air chamber it, to which there is a Vpassage z', from the uppermost mold. This air vessel is fitted some distance from its top and bottom with a cock j.

F is the three-way cock fitted to the bend of the conducting pipe and having its passages so arranged, as indicated in Fig. 2, by dotted lines, that a communication may be established from the cistern to and through I the spigot c, or from the part of the pipe C, A

on either side of it to the atmosphere.

. As many mold boxes are provided for one apparatus as are necessary to provide for the cooling of the molds to a proper degree to permit the removal of the balls or cakes.

In the use of the apparatus the three-way cock is turned in a direction to close the part of the conducting pipe C, between it and the cistern A, and the valve m, is kept closed un'- til the contents of the cistern have been brought to a liquid state, and a mold box E, having been placed on the spigot c, as shown in Fig. l, the valve m, and cocks la, and j, are opened and the cock F, turned to a position to open a communication from the cistern to the mold box and close the pipe C, from the atmosphere. The soap then runs from the cistern through the pipe C, spigot c, and faucet socket g, into the mold box en- The conducting pipe C, has its terminal pori tering the lowest mold and owing upward from one to the other through the passages 7, f, till all are filled and through the passage z', into the air vessel it; and as soon as it begins to flow from the cock j, the latter cock is closed and the air which has remained in the said vessel above the said cock is compressed by the column in the pipe C, and cistern A, to the degree due to the height of said column. The three way cock F, is then turned to a position to close the pipe C, to-the mold box still keeping the said pipe closed to the atmosphere, and on the cock 7c, being closed the charged mold box may be removed and an empty one substituted for it on the spigot c, to be iilled in a similar manner;

The pressure due to the column in the pipe C, and cistern A, is retained vin the molds after the removal of the mold and` as the contents of the molds contract in,

cooling the air in the chamber h, expands and forces back into the mold enough of the soap which was left in the air chamber below to keep the molds filled, and so make theV balls or cakes perfectly solid and of t-he exact form of the molds, thus obviating the difficulty encountered in casting soap balls in the usual manner and in the apparatus ordinarily employed, viz: the impossibility oi' casting them solid and of the proper shape, which renders it necessary to submit them to a subsequent turning process.

lVhen the operation of casting is at any time to be suspended for a considerable period the three-way cock F, is turned to a position to keep the portion ofr the pipe between it and the cistern closed and to open the other part of the pipe for the purpose of allowing the material remaining in the spigot c, and portion of the pipe between it and the said cock to run through the said cock into a suitable receptacle placed below it, thus obviating the inconvenience that would occur in case of the said material cooling and setting in the last mentioned portion of the pipe. The material remaining in the other portion or" the pipe C, can also` be discharged` by turning the said. cock F, to a proper position, the valve m, having been previously closed.

Vhat we claim as our invention and desire. to ,secure by Letters Patent, is

rlhe attachment of the mold box E, to the conducting pipe C, in connection with an elevated cistern A, or other means of giving pressure to the liquid substance, by means of a spigot and faucetr c, j, or equivalent joint which permits the removal of the said `box from the said pipe and between which and the said box there is a stop vcock j 70,' all substantially as herein described.
