IMPllOVEMENT IN MACHINES {0R MIXING SOAP AND DTHE'R MATERIALS.

Specification forming part of Letters Patent No. 119,018, dated September 19,1871 reissue No.4,854, dated April To all whom it may concern Be it known that I, QHARLES ELLING, of Cleveland, in the county of Unyahoga and State of Ohio, have invented a new and Improved Machine for Mixing Soap and other Materials, of which the following is a description, reference being had to the accompanying drawing making a part of this specificamachine for the manufacture of soap; and the object thereof is to mix up the soap while in a fluid state so as to incorporate therewith no air, and thereby produce a more solid and finer article of soap.

Said machine is constructed and operated in the manner as fo11ows--viz.': In the drawing, Figs. 1 and 2, A represents a vat or tub, in which is a cylindrical case, B, Fig. 4, having an open top and bottom, and which is so arranged in said tub that it is elevated above the floor thereon on standards 0, thereby i'ormin g a space, D, between the lower end of the case and the floor of the vat, as shown in Fig. 4, the purpose of which will presently be shown. In said case B is erected a shaft, E, having a foot bearing in a step, F, whereas its upper end is supported in a beam, G, Figs. 2 and 3. On the shai't referred to is secured a screw, H, having a broad thin thread, as shown in Fig. 5, the diameter of which is but little less than that of the case in which it is fitted, and made to revolve by means of the miter-wheel I secured to theupper end of the shaft, and which wheel is made to engage a corresponding miter-wheel, J, on the shaft K.

The practical operation of this machine is as follows: The ingredients of the soap, while in an unmixed and fluid condition, are put into the vat for being mixed together, and which mixingis done .by turning the; screw in direction of the arrow, thereby causing the material to work upward from the bottom through the surface of the screw revolving in the case and discharging the same over the top, and which is bcin g constantly replaced by the soap from the vat, which finds its way into the case through the space I) below. By this means the mix ing is done at the bottom of the vat without greatly agitating thesnrface of the material; hence there is none or but little air mixed up with the soap, so that it is less spongy and frothy when mixed ready for being molded. By this manner of mixing a harder -andmore solid soap is obtained than when the soap is mixed up in the ordinarymanner, agitating it in such way as to expose it to the air, which, being incorporated therewith, makes the soap porous and soft.

In this process of mixing there is established a current of soap from the bottom of the vat to the top of the inside of the case, over which it pours into the vat again, during which time it is thoroughly stirred and mixed up ready for the molds. By reversing the action of the screw current is caused from the top to the bottom, which, however, is not so favorable in its results as when the mixture is worked upward from the bottom.

A is a pair of arms, whereby the mixture is preveu ted from becoming set in the vat as the arms pass through, thereby keeping it in motiom When the mixing of the soap. is completed it is drawn off through the bottom, an opening being made therein for thatpurpose, which, when not in use, is closed by a slide, B.

This machine can beemployed equally well for mixing other compounds, or paints, concrete, mortar, and other like compositions rcquiring mechanical action for their combination.
