SMALLEY MANU- OC. WISCONSIN. A CORPORATION OF WIS- IFEED-MIXING ATTACHMENT FOR FEED-CUTTERS.
Application filed May 29.
To all whom it may concern lie it known that l ()umix'no C. Fmon, a citizen of the United States, residin at Manitowoc, county of Mauitowoc, and btate of Wisconsin, have invented new and useful Improvements in Feed-Mixing Attachments for Feed-Cutters, of which the following is a specification.
My invention relates to improvements in feed mixing attachments for feed cutters.
The object of my invention is to provide means whereby the chopped or comminuted material delivered from a. feed cutter may be received in a mixing trough and fed laterally and mixed with other materials in a continuous operation. My invention contemplates the provision of a maehine in which meal, bran or other stock food may be fed into the mixing trough simultaneously with the delivery of material thereto from the feed cutter, and a more specific object of my invention is to provide efficient and inexpensive means, whereby the mixing operation may be con trolled both as to rapidity of feed and as to the character of the stirring effect to he secured by the mixing paddles.
In the drawings Figure 1 is a plan view of a feed cutting and mixing apparatus embodying my invention.
Fig. 2 is a side elevation of the same, showing the mixing trough partly in section.
Fig. 3 is a detail view of one of the paddles.
Fig. 4 is a view of the same taken angles to Fig. 3.
Like parts are identified by the same ref erenee characters throughout the several views.
A is a feed cutter of ordinary construction. The rear end of the feed cutter table B is connected with a supporting frame B which carries a. mixing trough G. A square shaft (1' extends longitudinally through the mixing trough and at one end is provided with a gear or sprocket wheel D, whereby the same may be actuated, preferably from the feed cutter shaft D, as shown in Fig. 1.
A set of mixing paddles E are mounted upon the shaft C. Each of these paddles has a screw threaded shank E, having threaded engagement in a mounting F provided with a square opening F through at right Specification of Letters Patent.

which the shaft C may pass. It is of course not essential that the shaft should be square in section, since any poly-sided shaft would serve the purpose. The opening in the mounting will of course correspond to the contour of the shaft.
By means of the mountings F, the addles may be adjusted upon the shaft (Q in any desired position. Each of these mountings serve as spacing members, and one or more of them may be provided with a looking set screw G, but it is not essential'that these set screws should be used, particularly where the mountings F from one end of the trough C to the ot er.

mountings until they engage the shaft and they may be utilized in connection with spacing members e to hind the mountings to the sha it C and also to lock the paddles at the desired angle. nuts ll alone where the type of paddle illustrated is employed.
To the type of paddles illustrated, the bladesare' eccentric to the axis of the shank, one side of the blade being wider than the other side. In the normal position of the paddles. the pressure of the mixture against the wider side of the blade is greater than that on the other portion of the blade and the excess pressure is exerted in such a manner as to force the lock nut into rigid engagement with the mounting and in such a Wanner that any tendency of the paddle to etate will tend to cause the screw threaded shank to turn inwardly into tighter engagement with the square shaft, or with the lock nut H.
At the end of the trough most distant from the feed cutter. it is provided with an outlet I through which the feed may be delivered to the endless conveyer J. whereby it may be transported to any suitable point of delivery.

fill the entire s ace fitted to a poly-sided shaft, it is obvious that they cannot rotate upon But owing to the fact that the shanks E of the paddles are screw threaded,
But l preferably use the lock \Vith the above described construction, 1 am able to adjust the paddles with the blades at any angle to the plane of rotation. 1 am also enabled to adjust some of the paddles at one angle and some at another angle, whereby some of the paddles may feed the material along the trough, other paddles may stir it without material longitudinal feeding movement, and others, if desired, may reverse the feeding movemenl and crowd the material toward. the receiving end of the trough. I preferably arrange the paddles so that the initial paddles will clear the material away from the feed cutter rapidly and also away from the outlet of the hopper K, through which other material, such as bran or meal, may be discharged into the out feed. The next succeeding paddles may he ad iusted with the flat suri'ares of their blades substantially at right angles to the plane of rotation. 1'. w. in planes whirl] include the axis of the shaft, preferably one paddle is so adjusted. and the next one is adjusted to feed the material longitudinally of the trough. Near the discharge end of the trough, one paddle may be adjusted to reverse the feeding movement. The ad justment of the paddles, however. will. depend largely upon the ehararter of the run-- terial to be mixed.
The above described eonstrurtion makes it possible to feed out stems of hay, straw, or i-orn stalks with great uniformity into the mixing drum or cylinder, such materials. after having once been cut, being of a l'lllllactor to render a feeding operation dili'ieult, since they Will not pass readily through the throat of a hopper, but will tend to clog the same. and any other means is also made diflicult from the fact that the stems are too short to be properly conveyed by means of feeding rollers, and too long and light in weight to be easily fed by any other rotative feeding means. By combining the mixing apparatus with a feed cutter, the long stems may be conveniently handled and presented with substantial uniformity to the rotary cutting knives and the short stems delivered from the knives are thrown into the mixing cylinder in the best possible position to receive ground feed. such as may he delivered through the hopper K.
I claim- A mixing attachment including a trough adapted to receive feed, a shaft extending longitudinally in the trough, means for actuating; the shaft, a set of individually removable mountings, eaeh adapted to lit the shaft, each non-rotatable thereon and ear-h provided with a threaded soi'liet, a set of mixing paddles havin threaded shanks mounted in said sockets and extending to a greater extent on one side of the axis thereof than on the opposite side thereof. said paddles being adjustable at various angles, and having blades so arranged with reference to the axes of their shanks. that the pressure of the material upon the wider side of the blade tends to rotate it in the mounting socket, and eaeh shank being provided with means adapted to seat upon the mounting, and to be forced into bindingpressure engagement with it to hold the l; adia wins-1t rotation.
In testimony whereof I affix my signature in the pressure of two witnesses.
