APPARATUS FOR MIXING SOAP AND OTHER MATERIALS.

SPECIFICATION forming part of Letters Patent NO. 228,320, dated June 1, 1880.

Application filed August 23, 1879.

To all whom it may concern:

Be it known that we, WILLIAM CORNWALL, $13., WILLIAM CORNWALL, J r., and AARON W. CORNWALL, of the city of Louisville and county of J efierson, in the State of Kentucky, have invented a machine for mixing and combining liquid and plastic substances with each other in the manufacture of soap, or dry materials with liquid or plastic substances or with other dry materials, for various purposes, of which the following is a specification.

Our invention is an improved machine for mixing materials suitable for making soap, also for mixing other plastic or pulverulent materials for other purposes.

The improvement consists in the construc tion and arrangement of the rotating arms employed for creating currents, which move in opposite directions, butin different parts of the materials placed in the mixing vessel or receptacle.

In accompanying drawings, Figure 1 is a vertical longitudinal section, and Fig. 2 a vertical cross-section, of our improved machine. arms or stirrers detached from its shaft. v

The stirrers or mixing-arms A B are fast on a shaft, D, which extends through the longitudinal axis of the mixing chamber or receptacle C. Said shaft D may be rotated by a hand-crank, H, or a band (not shown) running on pulley K.

Each of the aforesaid arms consists of a metal plate whose broad ends A B constitute paddles, which, when the shaft D revolves, cause different currents in the plastic material placed in receptacle C.

Each of the paddles A and B is inclined horizontally at an angle of about forty degrees to the axis or shaft D, as shown; but the arms, taken as a whole, are nearly radial to said shaft.

The arms are arranged spirally or in a spiral line around the shaft and at equidistant points. They are each provided with hubs a, through which the shaft D passes, and said hubs are located at the inner ends of paddles B, so that the paddle A is at the end of thelonger part of the arm and describes the larger circle.

It will be perceived that upon rotating the shaft D in the direction indicated by the arrow on pulleyKthe paddles A will force the plastic material toward the right and the paddles B Fig. 3 is a plan view of one of the a different part of the materials being mixedthat is to say, the currents caused by the short paddles B are between the shaft D and paddles A. The 'two currents thus set up in different parts of the same substance progress toward opposite ends of the receptacle 0, come in contact, and intermingle more or less as they move along in a whirling motion, and on reaching the ends of the receptacle rebound, and finally become thoroughly mixed and form a homogeneous mass, which result is produced more quickly and with less expenditure of force than in other mixing-machines in which violent agitation of the plastic material is obtained by rapid motions that set currents in motion against one another, so that the two or more opposing currents meet and in part destroy each other.

WVe show in Fig. 1 an arm having paddles A B, which is placed with its transverse plane inclined opposite to the others, for the purpose of assisting in breaking up the currents and producing the desired speedy reduction to homogeneity.

What We claim is- In a mixing-machine, the combination, with a shaft adapted to rotate in a suitable receptacle, of a series of spirally-arranged arms or stirrers, having broad ends, forming paddles A B, which are inclined to the shaft and arranged as described, with paddles B nearer the shaft than paddles A are, substantially as shown and described, whereby the respective paddles will sweep in different but concentric circles, and create currents in opposite directions, but in different parts of the same sub-.

stance.
