Application May 3, 1948, Sensible. 24,1714 1 7 Claims; 1

This invention relates to a feed mixer.

An object of this invention is the production of an efiicient and novel machine which will mix molasses into dairy feeds after said feeds have been first mixed in a dry state, in a regular feed mixer and made ready for the molasses;

It is to be understood that feedis spouted'from the regular sacking spout of the main mixer into theupper chamber of the pre-m-ix'er, where it is metby a: stream of molasses. The two then pass downwardly, by force of gravity, and are" mixed and commingled thoroughly before enterme back into the mainmixer.

Another obiect of this invention is the construction of a novel apparatus which can be used in conjunctionwithmain mixers provided with a loading hopper,xeither above or below the floor; this is accomplished by the extreme compactness of my invention and its powerful and complete mixing agitation, requiring much less power than ordinary mixers for asimilar purpose.

A still further object of this invention is the production of a mixer that is portable so that it can be operated by one man to quickly and easily move to and from the main mixer. It is-to be understood that the main mixer may be utilized for mixing feedsother'than those containing molasses, at which time the pre-mixer must be removed while sacking from the spout of. the main mixer.

Another object of the invention is to mount the pro-mixer cylinder ortube at a high angleabove the horizontal and below the vertical,

whereby the machine can be driven by a motor without using belts or pulleys, and yet operating with high eflicien'cy.

A still further object of the-invention is to so construct the apparatus whereby the mixer. body is suspended fronrabar, allowing the mixer-body to pivot and swing to enable the apparatus tohe slipped into an operative position with respect to the loading hopper 01 a' conventional feed mixer.

With thefo're'goingand other objects in view, this invention comprises certain novel construction's, combinations, and arrangements of parts as: will be hereinafter fully described, illustrated in the accompanying drawings,v and more par ticularly pointed out in the'appended claims.

In th drawings:

Figure 1 is a view inside-elevation of an an paratusconstructed in: accordance with the present: invention, showing. same assembled with on line':i--5-, Fig. 2, and looking in the direction of the arrows.

Figure-6 a horizontal. sectional view, taken on line 6--6'=, Fig. 2 andlooking in the direction of the arrows.

Referring to; the drawings,- in. which I have shown the-preferred embodiment of this invention, I designates a conventional feed mixer, which is provided with the auger tube 2 and the feed mixerspout 3.

The novel apparatus of this invention comprises a frame", including side bars 4 and. rear legs 5-. A handle 6- has the lower ends of side oars 4 fixedly secured: thereto; Each side portion I is bent upwardly at 8. and on this bent up portion 8is a roller or a wheel 9. Therefore, when the. apparatus is at rest, Figs. 1 and 2, the bent portions-8' will be engaging. the support; and the apparatus will. be held stationary. The handle 6- extends beyond the rear legs 5. The rear legs 5 are connected-by two horizontal bare it and H. A" mixing tube IZ- isprovided, which isopen at'itslowerend (Fig.2), Themixing tube 12 isclosedat its upper. end, and is provided withair outwardly extending feed spout I3. This feedspout' I3: is open at anuangle so as to fit snugly against, the bottomend of feed mixer spout 3,. as shownin Figure 1. The feed spout I3 is provided with ad'ry feed-.by-pass aperture M. This aperture M permits a percentage of dry feed to by-pass the molasses-mixing chambar to keep the wet feed from adhering to the auger. A shaft. I 5 extends through the sides of flanged shield H5, and the ends of shaft t5 are in the side bars. 4 The flanged shield I16 partly surroundsthe electric motor H, as well as supports the base l8 on which the motor I! is mounted. The lower portion. of the shield I6 is suitably secured to the upper portion of the mixer tube l2. Therefore, it will be seen that the tube l2, shield 16,- and motor I! have a pivotal or swinging movement on the shaft l5.

Within the mixer tube 12 isa stirrer shaft IS onwhich is mounted the heaters 20; these beaters are positioned at an angle and. are staggered, whereby they wipe the tube [2 clean when operating. A molasses supply pipe of tube 2| extends into the topportionof mixer tube- !2, as clearly seeninFigurez. y

In. operation, the handle 5 is; grasped and movedupwardly soathat' the wheels 9 engage the floor: or: platform, whereupon the operator can quickly; move. the apparatus, as. desired. In. positioning the. apparatus, as shown. in Figure 1 the lower end of them-ixingtube i2 is. swung upward to clear the top of. the loading hopper 22, and then isnioved downwardly-,by being pivoted on shaft I5, permitting. the teedspout It to be positioned under spout- 3., By reason of. the

:I ,peeuliars construction of this apparatus, this 25 are placed over the two bars Hi and H.

so that the tips thereof have a wiping effect on the walls quite clean of adhering molasses and i lessens the frequency of washing.

In Figure l, there is shown a washing tank 23.- The water is usually maintained in saidtank to the height of line 24. The tank 23 is provided with hooks 25 on its rear portion, which hooks 5 A hook or flange 26 is on the bottom of tank 23 and engages a loose bar 21. The weight of the tank holds the loose bar 21 against the side bars 4 and against the inner face of the flange or hook 26, whereby the tank is maintained in a horizontal position. This tank can be quickly applied to the apparatus, or removed therefrom.

as the operator desires.

The shaft i9 is rotated by means of motor ll.

Usually the feed is passed down through spout 3 into spout l3 and thence to the mixer tube, where said feed is impregnated with molasses that is thoroughly mixed by the novel stirrers,

the whole mass moving downwardly by gravit to the lower end of the tube l2, and thence into the loading hopper 22, from where the feed is taken up through the auger tube 2 into the upper part of the conventional feed mixer.

The upper beater in the mixer acts as a power- 5 meter which meters the feed into the-machine and when the rotor stops, the feed ceases to flow thru machine. Each revolution of the beater arm shakes a given amount of feed down thru mixing chamber so as to maintain a fixed, or 0 adjustable ratio of quantity between the liquid and the dry materials. This is important in that it makes it possible to produce a uniform mixture as to percentage of molasses used.

While I have described the preferred embodir merit of my invention and illustrated the same in the aoompanying drawings, certain minor changes or alterations may appear to one skilled in the art to which this invention relates during the extensive manufacture of the same, and I,

therefore, reserve the right to make such changes or alterations as shall fairly fall within the scope of the appended claims.
