My invention relates to mixingapparatus, and more particularly to apparatus or'mixing food materials for live stock,-but it may be employed in mixing materials of other I! kinds. 7

One object of my invention is to provide apparatus for effectively mixing materials into which is introduced a liquid. content such as molasses, for example.

19 Another object of my invention is to provide in combination with a mixing apparatus,

means for more effectively removing the mixed materials therefrom. a

A further object ofmy invention is to provide an improved means for charging the materials to the mixing apparatus.

Another object of my invent-ion is to provide means for more effectively circulating materials during a mixing operation and for intermixing the materials to produce a thorough dissemination of the various ingredients through the resulting mixture.

Still another object of my invention is to simplify and im rove generallfv the structure 25 and operation 0 apparatus 0 the character referred to.

One form of apparatus by which my invention may be practised is shown in the accompanying drawin wherein Figure 1 is a 80 view thereof partia in side elevation and partially in section; ig. 2 is an edge elevational view thereof; Fig. 3 is a plan view;

Fi 4 is a view, on an enlarged scale, showing"details of a portion of the conveyer, and Fig. 5, is a cross sectional view of the apparatus of Fig. 4.

The apparatus includes a mixing chamber 6 of hopper-like form in its lower portion 7, within which is mounted a vertically-disposed conduit 8 that is flared at its lower end 9. A conveyer chain 10 which carries vanes 11 moves through a continuous path that extends upwardly through the conduit 8 and returns to the lower end of the mixing chamher through a casing 12. The conveyer also passes through a charging chamber or material-receiving chamber or hopper 13 that is wantedbelow the floor level and has communication with the hopper 7. A charging 50 opening 14 is provided in the floor and such opening may be covered by a platform or plate 15 when material is not being dumped into the hopper 13. v

The conveyer chainpasses around a sprock casing 12. The'chain is driven by the sprock-v et wheel 18 from a shaft 19 which carries a pulley 21 that may be driven from any suitable source of power, the shaft 19 having driving connection through sprocket wheels and a chain 22 with a shaft which carries the sprocket wheel 18.

It will be seen that when materials, are introduced into the charging chamber 13, they will be caught by the moving vanes of the conveyer and carried through the conduit8. The materials are discharged at the upper end of the conduit 8 in the form of a spray and fall or sink into the hopper 7. The materials are charged into the chamber 13, until a sulficient quantity hasaccummulated in the mixing chamber 6 or until such chamber is nearly full.

Continued travel of the conveyer will circulate the material repeatedly through the conduit 8 to. effect thorough intermixing thereof. If molasses or some other mixture has to be incorporated in the mixture, it may be introduced into the mixing chamber, through pipes 24.

As the material passes from the upper the mixing chamber 6 into the casing 12. To

this end, I provide chutes or troughs 28 and 29 that are pivotally mounted in the upper end of the casing. The trough 28 is' piv- 05 plate 15 is held in open position by a latch 43.

oted at 31 and carries a crank arm 32, while the trough 29 is loosely mounted on the shaft which carries the sprocket 17 and has a crank-like extension 33. The extension 33 is connected th ht l links34 to the trough 28.1 I

Ordinarily, the troughs occupy thepositions shown in Fig. 1, so that there will be no interference with circulation of the ma terials in the mixing chamber.

After the materials have been thoroughly chute 28 to break the toggle and to retract.

the chute 29'when the chute 28 is being swung to inoperative or retracted position.

'When the chutes 29 and 28 occupy the positions shown in dotted lines in Fig. 1, they will direct the material from the upper end of the conduit 8 laterally to the casing 12. A

deflecting plate 38 is provided in-such casing, to direct the material toward the outer wall thereof and .to a position where it will fallto the discharge spout39 of the casing.

It will be seen that the downwardly-moving run of the conveyer chain 10 is inclined and that the vanes 11 thereof slope toward the outer wall of the casing 12. This arrangement results in any material which falls upon the upper sides of the descending vanes 11 being deflected still furtherlaterally to ward the discharge spout 39.

Another advantage arising from directing the conveyer through a generally horizontal path at the upper end of the mixing chamberresides in the fact that it enables the return run of the conveyer to lie outside of the mixing chamber. If both vertical runs of the conveyer were located entirely in the mixing chamber, it willbe seen that there would be a tendency for a portion only of the materials to be circulated by the conveyer, leaving the other portions thereof undisturbe The discharge spout is controlled by a valve 41 which is operated by a handle 42. When the handle 42 is raised, the upper edge of the valve 41 is swung toward the conveyer chain, thus permitting material to fall through the spout 39 into 'sacksor other receptacles placed therebeneath. I

The hinged, plate 15 serves not only as a platform, but as a cover for the chamber 13. When the chamber 13 is being charged, the

beneath the spout 39 to receive the mixed materials. Thefree'edge of the platform 15 is supported upon pins 44 that are carried by the outer ends of a pair of arms 45 which are pivoted at 46. Upon the ends of a shaft'47 which carries the sprocket 16', are secured polygonally-shaped discs or plates 48 against which the lower ends of the arms 45 bear, the

weight of. the: platform 15 j serving. to. hold such lower ends in engagement with the discs 48. As the shaft 47 rotates, the discs 48 Will cause oscillation of the arms 45 about their pivots'46, thus vibrating the platform 15' and effecting settling and compacting of the materials in the bags being filled.

Certain of the vanes 11 carry wiping strips 11 as shown more clearly in Figs.'4 and 5,

to serve as scrapers and prevent accumulation of material against the walls of the conduit 8. These strips may be of fiber board or any other suitable material.

The apparatus above described is show as mounted within a framework 50 of angle work-parts, so that the entire apparatus can be shipped in assembled condition and conveniently'installed at the place of use.
