This invention relates to devices whereby molasses in a cold condition can be mixed with and into grain which has been ground to the consistency of flour, and the general object of this invention is to provide-a mechanism of this character so constructed that molasses in the form of a spray will be mixed with the groundgrain also in the form of aspray as it may be termed, and a further object is to provide means for thispurpose which is so designed that a predetermined amount of molasses may bemixed with a predetermined amount of grain so that in the mixture, the grainand the molasses will have certain proportions. I A further object is to provide a construction of this character which includes means for throwing the grain centrifugally outward and forward and means for spraying the molasses on to this grain as it is so thrown and a further object is to; provide a machine-of this character in which a tank is used for holding the grain and wherein the tank is moved backward and forward preferably automatically, causing the mixing paddles to mix the grain from one end of the tank to the other. 7 i Other objects will appear in the the following description.

My invention is illustrated in the accompanying drawings, wherein I Figure 1 is a longitudinal sectional View through a molasses mixer constructed in accordance with my invention.

Figure 2 is a section on the line 22 of Figure 1. 7

Referring to these drawings, 10 designates a tank which may be made of metal or other suitable material, which tank is mounted upon the wheels 11 running on tracks 12, the tracks 12 having a length approximately equal to twice the length of the tank 10. Supports 13 of any suitable character support a shaft 14 which extendslongitudinally course of 4 through the tank and with which the tank has sliding engagement. 7

Disposed upon the middle of this shaft, for instance, is a cylindrical hub 15 and disposed on each side of this hub are disks 16 whichtarry upon their peripheries the vanes or blades 17 which will be later adverted to. Mounted upon the top of the tank is a supporting'frame 18 which carries a hopper or like molasses reservoir 19 from which a pipe 7 20 extends downward and discharges against the face of the middle portion of the hub 15, the lower end of the pipe beingspaced from this hub'anysuitable distance. 7

The tube 20 discharges the molasses against the hub 15 which is rotating at a high rate of speed and the rotating hub'throws the molasses off out-ward by centrifugal forcein the form of a more or less fine spray toward the circumferential wall of thetank.

Disposed at the peripheries of the disks as previously stated or adjacent thereto are the paddles, vanes or blades 17 These have straight shanks which may be attached to the disks 16 and the paddles or vanes are twisted at an angle to the plane of the disk 16 or in the manner of fan blades or propeller blades. In the useof this mechanism, the grain to a predetermined amount is filled in to one end of the tank 10, the tank having a lid 22 at the top for this purpose and having an opening, atfor instance, the right hand end of the tank, at its bottom for the purpose of discharging the mixed} grain and molasses.

l/Vhen the grain has been disposed within the left-handend of the tank in Figurel and cold molasses disposed within the hopper or reservoir 19, the shaftis rotated by a motor or other suitable mechanism at a high speed while at the same time the tank is slowly pushed toward the right on its wheels '11, thereby bringing the feed in contact with the paddles or vanes 17, which, by their be ing angled, throw the feed in a spray toward the right. The'feed or grain passes between the edges of the disks'16 and the wall of the tank and at this point the grain or feed comes in contact with the spray of molasses that is being thrown out from the hub 15. The paddles or vanes 17 throw the feed with such force that it is thrown to the right hand of the tank and there piles up while the tank is gradually pushed to the right.v Eventual- 1y all of the feed will have been fed to the the tank. When the tank has been shifted to its full extent to the right, the paddles, disks and the molasses discharge pipe meat the left hand end of the tank.

Then if it be desired to continue the mixing without mixing any more molasses,the supply .of molasses is cut off and the disks-and paddles are reversely rotated to throw the feed from the right hand end of the tank to the left hand eas er the-tank 'and'more thoroughly mix the feed with the inol'asses or a further amount of molasses may be. discharged through the molasses supply pipe against the hopper and the grain still further mixed with molasses until precisely the proper proportion of molassesand grain-has been secured. Thus '.it will be'obvious that the tank may be shifted backward and forward a number of times and each time an ad ditional amount of molasses may be sprayed into the grain. I

It will be understood that the molasses used is thick and gummy and, therefore, it is necessary to convert it into a relatively fine spray by causing the; molasses to flow uponthe revolving hub. This hub in actual practice is about six inches in diameter and a smallstream of molasses coming in contact with the hub is't'hown off fromfthe hub in the form-of a very fine spray; The purpose of the two disks 16 isto protect the hub and prevent the grain coming in contact with the molasses at the point where it hits the hub and before it is thrown from the hub in the form of a spray. The molasses is protected from contact with the grain by flowing through the pipe 20. Th'e tank, it will be understood, is only a means of causing the grain to come in contact with this fine spray 1 of molasses but the tank is necessaryas it is the only means which will hold a specified amount of grain so thata specified amount of molasses can be mixed in with a specified amount of grain. Thus I have provided a machine which will thoroughly mix a pre-' determined and certain amount of molasses into a predetermined and certain amount; of feed. In other words, I have provided a batch molasses mixer.

It is within the purview of my invention to mix molasses with 'anykind of feed which is passing through or is confined within any kind of a drum or -tank that has within it fast revolving blades and which is provided with means whereby themolassesmay be thrown off intheform of a relatively fine spray through, which the grain is caused to pass. Themolasses may thus bemixed into groun'd grain or any other relatively fine or comminuted material to which the molasses will stick if the grain and the molasses are separately reduced to. a spray, and then thrown together ,in mid air, My tank or' I drum is designed to hold several hundred pounds of grain. or meal. It is further so.

able'blades maybe reversed by reversing the motor used for driving the shaft 14 or. by any reversing mechanism and then, after the tanklor drum-has been pushedisufficiently far tothe right the tank motion of the blades maybe reversed and the tank then pushed from the right toward the left. I have not illustrated any reversing mechanism because such reversal involves merely the reversal of th'e motor or the use of reversing gear which is an obvious construction;

VVhi'le I have illustrated certain details of construction and arrangements of parts, I donot wish to be limited thereto as'obvious'lythese might be varied in many ways witho'ut departing from the spirit of the invention as defined in the appended claims.

VVhi'le I have shown ahand operated valve for controlling the passage of molasses, it is to be understood, that 1* may provide a valve which will shutoff when thetank has moved to the end 'ofits stroke in one-direction. Nor do I wish to be limited to theexact form of blades whereby the grain isthrown through thespray of molasses; nor to the exact construction of'the movable. tank and theouter casing as these parts might be varied without departing from the spirit of the invention.
