n 5 M` @im @M I travels in a direction from left to right in Fig.. 4, it being understood that the upper flight of the conveyor (not shown), travels rearwardly or toward the direction of rota-u tion of the rotor.

The rotor is made up chiefly 'of a central operating shaft 4.of cylindrical form (see 1 Fig. 2). .Spaced radially from-this shaft are the circumferentially spacedv rows of teeth 5. The teeth are mounted upon angle bars 6 and each angle bar is in turnmounted upon a crank rod bar 7 loi substantially square crosssection. As shownplamly in Fig. 6, the outer ends of the rods terminate j heads at the ends ofthe rods, I would stateV that each head (see Figs. 2 and 4) comprises a disk 12 which is yformed at its center with a hub 13 keyed at 14 to the shaft 4. Adjacent Vits periphery, this disk is provided -with bearings 15 to accommodate the aforesaid journals 7'?. In' addition, it is formed with a peripheral angel and this flange is rotatably mounted lupon a relatively stationary drum indicatedgenerally by the reference character 17. This drum is rigidly fastened upon the wagon body.

At this time, I would direct attention to Fig. 7 wherein it will be seen that the drum is provided on its inner face with an eccentrically disposed ,channel 18V in which the aforesaid rollers 9 are mounted for rotation. In addition the drum is provided with a central hub 19, a portion of which serves to accommodate a roller bearing 20 for the adjacent end portionof the shaft4. lIt will be noticed that the outerl 1end o'this hub is constructed to provide a convex enlargement 21 turnable in a bearing 22 of corresponding construction. I` might state here that the purpose of the bearing constructed by the parts21 and 22-is to allowthe drum 17' to be lturned in order'to dispose the eccentric channel 18 at the proper point at ther time of installing the device upon the wagon body or manure spreader. The bearing 4becomes substantially inoperative after the drum ispermanently fastened.

With this arrangement, however, it is ob- ;vious that the member comprising the disk .12 andthe fiange16 rotates about the periphery of the fixed drum.

From the foregoing, itwill be seen that Ihave produced a rotary.l element provided with a plurality ofrows of raking and dischargin teeth. Y Each row. is rockabl mounte upon the. end head. lItfollowsthat during the revolution of the rotor, the teeth j bar 7 and teethV carrying means 6 will rotate therewith. In addition, .the disks 12 and flanges 1'6 will rotate about the drums. As

each fixed drum is provided with an eccentric channel and as the crank arms have the rollers located in the channel, 1t is obvious that the manure, moving swiftly to the rear ladjacent the top of the rotor, will beginto leave the teeth as the lattenmove downwardly" and rotate on the journals 7a in a direction contrary to the-directionvof rotation of the rotor as a whole, so thatwhen the teeth vget around near theibottom of the'. wagon body,the travel of the rollers in; the channel willhave serv'edto actuate the teeth in a mannerntofhave forcibly ejected andA dis-A charged the manure therefrom.

It is believed that by considering| the desc-ription in. connection with the drawings, persons-familiar with inventions of this class will be able to obtain a clear understanding of the same. Therefore a more lengthy description is thought unnecessary. f
