SOAP-PLOTTI NG MAC H IN E.

SPECIFICATION forming part of Letters Patent No. 711,493, dated October 1902- Application filed February 1, 1900. Serial No. 3,602. (life model.)

To all whom it may concern:

Be it known that I, LOUIS GoTTsoHALK, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Soap-Plotting Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a novel construetion in a soap-plotting machine, the object being to provide a device which will deliver a continuous finished or glacd bar; and it consists in the features of construction and combinations of parts hereinafter fully described and claimed.

In the accompanying drawings, illustrating my invention, Figure l is a vertical longitudinal section of a machine constructed in accordance with my invention on the line 1 1 of Fig. 2. Fig. 2 is a transverse section on the line 2 2 of Fig. 1. Figs. 3 and 4 are respectively an end and side elevation of one of the sleeves carrying stirrer-arms. Figs. 5, 6, and 7 are front elevations of dies to be mounted at the delivery end of the machine for forming the bar. 7

In plotting-machines it is desirable that the soap should be formed into a continuous bar irrespective of the percentage of moisture contained in the soap, that such bar should be free of anyajlgeore and pei fiecitlylhomogeneous, should have a perfectly smooth finished surface, which when dry prevents loss of weight and warping, and which will permit a bar of any desired shape in cross-section to be formed. To these and other ends I have constructed a machine comprising a cylindrical shell A, tapered at one end B to form a contraction, such contracted end bethrough said shell and carries a spiral conveyor F at one end, said conveyor fitting closely within said shell A and conforming to the shape thereof.

motion.

Behind said conveyer F said shaft carries a plurality of stirrers G, each consisting of a sleeve rigidly mounted on said shaft and carrying aradial arm integral therewith, which is set at an angle of about forty-five degrees to the direction of Said stirrers Gare so set on said shaft that said arms lie in a spiral. A hopper H to receive the soap chips is provided at the rear end of the shell, and in the pas- 6o sage connecting said hopper with said shell and immediately below the mouth of said hopper are journaled two parallel crushingrollers I, between which the contents of the hopper are obliged to pass to enter the shell A. The said shell A is provided with a sur rounding jacket .I almost its entire length and is adapted to be connected with a source of supply of an attemperating fluid by means of pipes K and L, thus enabling me to regulate the temperature of the soap in said shell. The side die or former C,1is provided with an annular hollow shell M, forming a steamacket surrounding the delivery-opening and which is connected with a source of supply of steam by means of the pipes N. Said opening D in said die or former is preferably provided with slightly-convex inner faces, so that it is contracted at its middle portion, thereby acting on the bar in the manner of a polish- 8o ing-iron and presenting no sharp corner which could in any way roughen the surface of the bar. As the walls of said opening are heated, the surface of the bar will be softened and the soap prevented from adhering thereto, so that no roughening of the surface is possible. In Figs. 5, 6, and 7 I have shown dies or formore for producing bars of varying shapes. The said shaft. E is driven from a parallel counter-shaft O by means of intermeshing 9o gears P and Q. The crushing-rollers I are geared to'each other and to said gear-wheel Q.

I claim as my invention- 1. In a soap-plotting machine, the combination with a casing provided at one end with an inlet for soap and tapered at its other end to form a contracted portion, and devices interposed in said inlet for feeding soap, of a delivery-spout on said contracted end of said casing, a shaft passing centrally through said 1cocasing and terminating adjacent said delivcry-spout, and a spiral screw carried by said shaft and fitting snugly within said casing, Ibe mounted upon the delivery end of said said screw being tapered at one end to fit said tapered end of said casing.

2. In a soap-plotting machine, the combination With a shell adapted to receive soap at one end,and devices Within said shell for compressing said soap and forcing it out through the other end, of a die or former adapted to be mounted upon the delivery end of said shell and provided with a central opening adapted to form said soap into a continuous bar as it passes therethrough, said opening being contracted at its middle portion.

3. In a soap-plotting machine, the combination with a shell adapted to receive soap at one end,and devices Within said shell for compressing said soap and forcing it out through the other end, of a die or former adapted to be mounted upon the delivery end of said shell and provided with a central opening adapted to form said soap into a continuous bar as it passes therethrough, said opening being contracted between its ends.

4. In a soap-plotting machine, the co mbination with a shell adapted to receive soap at one end,and devices within said shell for compressing said soap and forcing it out through the other end, of a die or former adapted to shell and provided with a central opening adapted to form said soap into a continuous bar as it passes therethrough, said opening being contracted between its ends, and a steam-jacket surrounding said opening.

5. In a soap-plotting machine, the combina tion with a cylindrical shell adapted to receive a die or former at one end and provided with a feed-hopper at its other end, of parallel crushing-rollers mounted below the delivery end of said hopper, and a shaft passing centrally through said shell and carrying a plurality of radial arms inclined at an angle to their direction of motion adapted to ster and cut the material leaving said crushing-rollers and move same toward the delivery end of said shell, and a spiral conveyer carried by said shaft and fitting snugly Within said shell, adapted to receive and compress said material and force same through said former.

In testimony whereof I affix my signature in presence of two witnesses.

LOUIS GOTTSCHALK. Witnesses:

RUDOLPH \VM. LoTz, JOHN CASSLEMAN.
