Application med January 29', 1,883. (No moda.)

To a/ZZ whom mcty concern.-

grooves in the eyes receiving ribs on the boxes.

Beitknownthatl,FLAvIUslUNDERWooD, `(See Figs. 4 and 5.) The inner ends of the of North Springfield, in the county of- Green and State of Missouri, have invented a certain new and useful Improvement in Rotary Golters, of which the following is afull, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in which- Figure 1 is a side View; Fig. 2, a front View, being an edgeview of the cutter. Fig. 3r is a vertical section. Fig. 4 is an enlarged view of one of the eyes of the yoke` showing the grooves for receiving the ribs on the journalbox; and Fig. 5 is a similar view, showing the box in place.

M y invention relates to a rotary colter em- .bodying a blade or cutter, which is journaled or socket, E3, of the disk E.

to a frame or yoke, the frame or yoke being secured to the beam of the plow by suitable nl eans; and my invention consists in the manner of connecting the blade and yoke, as fully described and claimed hereinafter.

Referring to the drawings, A represents the blade or cutter; B, the yoke, and D a standard for connecting the yoke with the plow-beam. y

E E represent disks, between which the blade is clamped, that E having a central inwardly-eXtending projection,'E`l, over which the blade iits tightly, and which reaches through the blade, entering tightly a cavity This projection E is preferably made tapering, and the socket E3 correspondingly tapering, so that when the parts are pressed together they will remain lin that position without otherwise being fastened, `until they are put in the frame or yoke, this beingan assistance in putting the parts of the colter together and holding the blade in position. The disks have central openings or holes, as shown, through which the connecting-bolt I passes.

F Fv represent journalblocks, which fit againstthe disks, and which have flanges F2 upon their inner ends, respectively, and they fit into journal-boxes H H, having anges H2 H2, which are secured in the eyes B B of the yoke and held from turning therein by journal-boxes fit snugly against the flanges of the journal-blocks, orthere may be a slight play between them,' as shown'. The inner part of the flanges of the blocks are preferably tapered off, as shown, forming V-grooves E4 E4 between them andk the disks, which receive any dirt'falling from the blade, keeping it from the journals. The blocks have central openings to receive the connecting-bolt I, and their outer ends extend somewhat beyond the eyes ofthe yoke, as shown. so that when the connecting-bolt is put iu place and tightened up the boxes will not be pressed between the head and washer of the bolt and the Iianges of the j ournal-blocks, for then the blocks could not turn freely between them. The connectingboltis provided with a washer and nut at one end, as shown, and a head on the other end. The blade,disks, journal-blocks, and connecting-bolt are supposed to turn together, the journal-blocks turning in the j ournal-boxes, as stated. The journal-boxes maybe made of any suitable material-as, for instance, composition,wood, metal, or rawhide; or they may be made from a self lubricating material-as, for instance. vulcanized fiber. The construction described is intended for the solid forked yoke;

but when the yoke is adjustable each disk may have its journal in 'one piece, with it, as Well as the iiange forming the V -shaped groove.

It is quite an advantage to Ahave the disks and" having rib-andgroove connection, and the eyes being received between the flanges of the journals and boxes, as set forth.
