SULKY MARROW AND PULVERIZER.

SPECIFICATION forming part of Letters Patent No. HSAOS, dated February 10, 1891.

Application filed August 28, 1890. Serial No. 363,258. (N model.)

To aZZ whom it may concern: tivating devices, which may be of any suit- Be it known that 1, CHARLES D. ROBERTS, able construction, but which are preferably a citizen of the United States, residing at Fairconstructed as follows: field, in the State of Illinois, have invented In Fig. 1 the frame is shown as connected 5 certain new and useful Improvements in to a V-shaped harrow, which is composed of Sulky Harrows and Pulverizers, of which the the rearwardly-diverging tooth-beams H H following is a specification, reference being suitably bolted to transverse bars F F, which had therein to the accompanying drawings. are in turn bolted to the longitudinal draft- Referring to the accompanying drawings, beams E E, these beams being connected and ro Figure 1 represents a perspective view of my braced by a transverse beam F, this beam improved cultivator, one of the wheels being F not being connected directly to the harremoved to better show the parts; Fig. 2, a row-beams.

presseddown firmly against the ground by pressing down with his foot upon the rear cross-beam of the harrow.

To open the front end of the harrow and slightly contract the rear end thereof, I provide the front cross-beam F with an extra row, the rear ends will be contracted, the bolts g" serving as the pivotal bolts on which-the tootlrbea in s turn.

-' Secured to the cross-beam F, so as to be in line with. the central line of the harrow, is a i forwardly-inclined'shovel 7L','Of suitable con- "-struction,"which serves toform a furrow "through: the center of the path-of the barrow, thereby serving as a'mark or guide for a corn-planteror seed-drill. To cutaway trash wand prevent itgathering upon the shovel, I employ a cutterh, which is secured-directly theharrow,-and which is inclined rearwardly in front-of the shovel to ablock II, carried by andsdownwardly, terminating near and in frontof the shovel.

"cutter and shovel absolutely prevents trash i'gath'ering upon then1,the trash thatis not i cutbeing carried down underthe shovel or forced to one side.

llIost of the trash will be cut, however, as the cutter is so arranged as w'to exert a'draw cut upon'the same.

Instead ofthe harrow shown in Figs. 1 and 2,1:may'attach to the draft-bars any suitable {apparatus for cultivating and pulverizing the soil. i For instance,I may employ the pulveraddition to the harrow.

izer shown in Figs. 3 and 4 in lieu of or in In this pulverizer 1 twoor more transverse series of the shovels 7t are secured to cross-beams j, carried by the =draft-beani,the shovels or blades of the front wiseries' alternating with thoseofthe rear se- TIES, as shown. transverse beams 1, directly in front of the Cutters h are secured to .1 shovels, to cut the trash, and thereby prevent it'gathering'upon the shovels,and to also'assist in the pulverization of the soil.

' To remove the harrow and substitute the x pulverizeig-and viceversa, it is simply neces- '..sary. to unhook the chains 6 and f from the d *aft-framc and remove the bolts upon which This arrangement-of the the rollers c c are journaled, as is evident. It is evident that the shovel h and its cutter (shown in Fig. 1) are not used when the harrow is adjusted as a straddle-row harrow.

Having thus fully described my invention, what I claim is- 1'. The combination of a frame mounted upon wheels, vertical beams D D depending from the forward end of the frame and braced by braces D D, vertical boxes I) b, secured to the lower ends of the said depending beams, a frame E E, provided with rollers at its forward ends adapted to workin the boxes I) b, cultivating means attached to this frame E, a

chains f f, connecting the rear ends of the frame E E to the said pivotedframe,:chains e e, connect-ing'the forwardendsof thef-rame E E to the pivoted frame, and rollers upon the frame, over which these chains pass.

In testimony whereof I affix my signature in presence oftwo witnesses.
