and

i. 1 3 V illustrated in Figures 1 and 3. By so constructing the device, a trough 40 is obtained, which will receive the feed supplied from the bin 22 and will not be scattered during the feeding process, as is usually the case with feeding devices employed today.

A pair of longitudinal shafts 42 extend longitudinally of the feeder and are secured to the side walls l4. The shafts 42 are substantially stationary and the two illustrated are provided, one

being for each side of the tapered walls 34. A plurality of individual rollers 44, best illustrated in Figure 4, are mounted on shafts 42 for rotation thereon. In the present embodiment, a total of six such rollers are supplied, each roller being positioned within the chamber provided by wall 36 and sides 14. The rollers 44 have secured on the outer periphery thereof teeth or button members 46, for a purpose presently to be described. The teeth are provided in spiral arrangement, as may be seen from an examination of the figures. The rollers 44 are positioned directly beneath the lower extremity of tapered walls 34 and above bottom l2 of the device. In this way, the rollers 44 operate as valves, or gate means whereby feed travelling from storage bin I6 is controlled by the operation of rollers 44.

Rods 48 extend longitudinally of the feeder l0 and one is provided for each side thereof. Welded to rods 48 are a plurality of depending bars 56 having lower ends terminating Slightly below walls 34 and are in constant engagement with teeth 46 and rollers 44. i The bars 59 are of flat, spring steel construction and are especially adapted to vibrate freely. Longitudinal rods 52 extend through feeder 19 below rods 43 and in parallel relation thereto, and contact the inner faces of the bars 56. The rods 52 thereby serve to limit the vibratory movement of bars 59 when they are agitated by rollers 44. While a plurality of fixed bars have been provided for each side of the feeder, the number may be varied as is needed to efficiently provide a steady supply of feed to troughAfl.

. In the use of the device, the rods 52 are adapted,

by actuation of rollers 44 to automatically supply feed as the feed is consumed. Roof 18 is pivoted into, open position, as was explained above, and bin 26 is filled. Roof l8 is then swung back into closed position and the feeding device is entirely closed against inclement weather. When an 4 Having described the invention, what is claimed as new is:

1. An automatic hog feeding device comprising a bin having a bottom wall, a pair of end walls secured to the bottom wall, a pair of downwardly and inwardly inclined side walls secured to said end walls and having lower edges spaced above said bottom wall and a closure supported by said end walls and said side walls, a pair of elongated apron forming members carried by the bottom wall and curved toward the side walls, said apron forming members being spaced above the bottom wall and having longitudinally spaced transverse slots, a purality of spaced parallel, substantially vertical spacer walls secured to the outer surfaces of said side walls and to the bottom wall to define a plurality of troughs, said spacer walls being received in said slots, said apron-forming members having openings therein providing entrances to feed disposed on the bottom Wall, means located within the bin and disposed between said side walls for agitating feed in the bin, and means mounted in said bin beneath said apron-forming members for directing feed in the bin toward the animal starts feeding, and particularly hogs, he

will root under rollers '44 at a selected trough. His snout gets under teeth 46, after which upon removing his snout, the teeth are urged upwardly and rollers 44 rotate. Feed is then enabled to travel into trough 40 by this movement. At the same time steel bars '56 are actuated and vibrated by teeth 46 upon which they engage thus preventing the feed from packing and storing in the bottom of bin 22. Apron forming members 38prevent any feedfrom overrunning trough 40 and being scattered or wasted thereby.

I From the above description, these several objects have been obtained. Any suitable material may be employed in the construction of the device, while a preferred embodiment of the invention has been shown and described, it is to be understood that various changes in size, shape and arrangement of parts might be made without departing from the spirit of the invention and the scope of the appended claims.

openings in said apron-forming members, said last-mentioned means actuating said agitating means. 2. The combination of clai'ml wherein said means for directing feed in the bin toward the openings in said apron-forming members includes a pair of longitudinally extending shafts carried by the end walls and the spacer walls, said shafts being spaced between the lower edges of the side walls and the bottom wall, and a plurality of toothed members rotatably mounted on the shafts and spaced from each other by said spacer walls. 3. The combination of claim 1 wherein said means for agitating feed in said bin includes a plurality of rods terminally fixed to said end walls and disposed longitudinally of said bin, a plurality of resilient arms carried by and depending from said rods, said arms having lower end portions extending below the lower edges of said side walls, and further rods fixed to said end Walls, said further rods being disposed intermediate the ends of said arms and contacting the arms, said arms being mounted for vertical swinging movement and said further rods limiting vertical swinging movement of said arms in one direction, each of the troughs having at least one arm associated therewith.
