Definitions

• Figure 1 is a longitudinal section of the mixing-trough, showing in'elevation two sets of the mixing devices.
• Fig. 2 is a cross-section on line 2 2 of Fig. 1.
• Fig. 3 is a sectional view of one of the spreaders, and
• Fig. 4 is a view of one of the plows.
• the mixing-trough A is a horizontallyplaced sheet-metal circular trough open at the top and at both ends. It is supported at the ends andA at one or more intermediate points by cast-iron inclosin g frames B. Cen-y trally through the troghpasses a shaft C, supported at its ends, outside of the trough, in suitable bearings. This shaft is driven at one end by a gear-wheel D, connected suitably with a source of power. At the ends and center of the shaft are secured cast-iron spiders E, upon which are securely bolted a number o f longitudinal bars F,'running parallel with the shaft. Five of these bars are shown, but a greater orless number may be employed.
• the spreaders arethrown outwardly by springs I, their outward movement being limited by the striking of the curved endb of the shoe against the block I-I, so that when the shoe leaves the surface of the trough its outward movement beyond the surface will be limited.
• the iuward movement of the spreaders is opposed by the springs. The inward movement permitted is so great with reference t0 the thickness of the material operated on that the springs are never wholly compressed.
• the plows are flat plates, having curvedends which do not come in actual contact with the trough, these plates being set at an angle, as shown.
• the plows K are secured to the bars F by keyblocks l).
• the plows and spreaders are placed close together side by side throughout the length of the bars F, the plows on one bar being set so that each will throw a ridge of material in the path of a spreader on the next succeeding bar.
• the materials to be mixed being fed into the trough at one end and the shaft rotated the mixture will be gradually advanced t0- ward the other end of the trough by the ac- 'tion of the plows.
• Each plow throws the mixture into a ridge, and the succeeding spreader spreads out the ridge and draws or kneads the mixture, producing an'intimate mixture of thefmaterials and preventing'the balling of the mixture.
• the rate vof progression of the mixture through the trough is slow, and it is subjected many times .to the action ? of the plows and spreaders. Indeed the material may be passed through a series of these mixers in succession.
• I provide a number of truss-rods L. These are bolted to blocks M, secured to the shaft Cnear its ends, but within the outside spiders E.
• the truss-rods L pass outwardly fromthe blocks M over arms c, projecting radially from the middle spider E.V
• a mixer the combination of a trough, a shaft mounted within said trough, aplurality of longitudinal bars supported by the shaft parallel therewith and a plurality of mixing deviees removably seeured to said bars and adjustable longitudinally thereon, substantially as set forth.
