WEEE-CUTTER AND CULTIVATOR;

SPECIFICATION forming part of Letters Eatent No. 629,015, dated July 18, 1899*.

Application iiled December 3, 1898. Serial No. 698,160. (No model.)

To all whom it may concern:

Be it' known that I, FRANK M. SHERRILL, a citizenof the United States, residing at In= dustry, in the county of Dickinson and State of Kansas, have invented certain new and useful Improvements in a Combined VVeed-Cut ter and Cultivator; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in combined weed-cutters and cultivators, and is especially designed foruse in workinglisted corn.

The invention embodies the constructions and combinations of parts hereinafter de-` scribed, and specifically pointed out in the claims.

In the accompanying drawings, wherein like letters of reference designate corresponding parts in the several views, Figure l is a plan view of a construction embodying my improvements. Fig. 2 is a side elevation. Fig. 3 is a side elevation of one of the supporting-frameworks detached; and Fig. 4 is a sectional view on the line 0c a; of Fig. 3.

Referring to said drawings, A designates the main frame of the machine, preferably This frame maybe' divided oft intofany desired number of secrectangular in shape.

tions; but for convenience in illustration three are shown, theybeing designated at B B B. These sections are spaced equidistant apart by division-walls C and C', there being two in each instance, with spaces D and D left between them. 4The frame A is peculiar` in cross-section toy afford the greatest possible strength, together with simplicity in construction, and comprises elongated parallel bars E and F, the former occupying a position relatively lower than the plane of the latter, and the connecting side pieces e e', formed with the horizontal enlarged portions f f and the rearwardly and upwardly eX- tending portions gg'.` The division-walls C and C correspond to the side pieces just referred to.

Mounted on a block E centrally of the frame on the bar E, rigidly secured to the bar F and extending forwardly in the plane of pivot in the bracket shown at @c ext-ends downward and terminates in the pintle oc'. On an axle passing through this pintle are the lead or guide wheels of the machine. In order that the guide-wheels may be locked in any desired position when the machine is temporarily out 'of use, a semicircular series of perforations g2 are provided in lthe plate G2, and these perforations are adapted to be engaged by a bolt g2, passing through the bracket G.

H, I-I', and H2 represent the main wheels of the machine and are of the usual type. The central wheels H' are adapted to revolve on a xed axle 7i', while the wheels H H2 revolve, respectively, on laterallyslidable axles 7L h2.

The object of having the outside sets of wheels slidably mounted is in order that they may adjust themselves to run in furrows varying slightly in distances apart. j

The ends of the axles h h2 are mounted in spring-boxings J, so as Lto accommodate for the unevenness of the ground.

Adapted to bear .on the under surface of the bar E and rigidly secured on the axles between the wheels of the respective sets are the bearing-blocksK, their inner ends being formed into segments L. To brace these blocks and hold them in properposition, I provide the U-shaped brackets M, pivoted to the axles and secured to 'a shoulder on the blocks by the inturned lugs m. Rollers m are secured to the brackets on their outer surfaces and arranged to run on the inner edge of the bar'E, and corresponding rollers m2 secured to projecting portions of the blocks are adapted to run on the under edge of the bar E.

In order that the weed-cutters and the plows may be held in adjusted positions and operated simultaneously, I provide the following construction: Pivoted on theaxles in the respective sections and adapted to engage with the segmentsL are the levers and springpawls l. VThe bifurcated ends of these levers IOO are extended some distance downward and are then in turn rigidly secured to the inner uptnrned ends of the cutter-blades N. Also secured rigidly to these bifurcated portions and having apertured ends fitting over the axles are the bars O. These bars extend rearwardly and constitute part of the framework P, comprising the pivoted outer bars p p' and the connecting-barspg. This framework affords the supporting means for shovels R, which may be of any usual or preferred construction.

From the foregoing description it will be seen that should the furrows in which the machine is working vary slightly in their distances apart the outer frameworks, together with the wheels and cultivating means therein, will readily adjust themselveslaterally in their loose bearings, the spaces D D permitting of such movement, and the frame sliding on the bar E through the medium of the antifriction-rollers before described, and the spring-boxings .I of the axles will permit of the vertical adjustment of the same to allow for the unevenness of the ground. I'Vhen it is desired to adjust the cutters and shovels, all that is necessary is to manipulate the levers and spring-pawls in the direction desired, and the cutter-blades being rigid on said levers, as also the shovels through the framework I), they will both be simultaneously and correspondingly operated in one or the other direction.

While there is shown in the drawings a particular embodiment of the invention for ac'- complishing the ends desired, it is to be understood that the invention is not thereby necessarily limited to such particular construction, as such is merely shown for purposes of delineation. Other means might be employed for accomplishing the same results.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-
