GEORGE H. WOODRUFF., OF JFRSFYVILLF, ILLINOIS,

Letters Patent No. 60,655', dated .December 18, 1866.

TO-ALL WHOM IT MAY CONCERN: l

Be. it known that I, GEORGE H. WOODRUFF, of J erseyville, in the county of, Jersey, and `State of Illinois, have invented a new and improved Combined Rollerv and Harrow; and I do hereby declare that the following is a full, clear, and exact description thereof reference being had to the accompanying drawings, vforming part of this ,specification I I The nature of my invention consists in combining two or more sections of eld rollers with a harrow in such a manner that the roller may be removed and the'harrow used, or separately employed from the barrow, so-

-that the ground may be rolled and harrowed at the same time, or only the harrow used, as may be desired, and

the nature of the work lshall require.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction, -and operation.

Figure I is a top plan View of my improved combined roller and harrow.

Figure 2 is a longitudinal vertical sectional elevation, tak'en through the line :n x.

Letters of like name and kind refer to like parts in each of the figures.

A represents a rectangular frame, madeof wood or other suitable material, with the side pieces extending to a suitable distance to therear for the purpose of supporting the\ rear end of the harrow. The framev A is mounted and runs on wheels, B B, which are provided with shafts and journals, which run in proper bearings firmly secured to the under side of therectangular frame Upon Ithe' shafts upon which are the wheels B B, are rollers, GC, made of wood of the same diameter as the wheels, the outer ends of which are made to it against the inside-of the rim of the wheels A AJ The wheels A A and rollers B B are secured upon the shaft by means of set-screws, so that the rollers may be removed as desired, and only the wheels employed. The frame A vis provided with a suitable cross-piece, D, `that passes between the sections of the rollers, to which the bearings of one end of the shafts are secured, and to which lis also secured, by a pivot-bolt, a, the pole E. To the rear cross-piece of the frame A are secured, by means `of the connecting-bars F F'F F F F, the harrow beams G G Gr Gr Gr G. -'.lhese connecting-bars, F, are bent twice at right -angles for the purpose of bringing the beams Gr to the proper height in relation' td` the frame 'A andto the ground, so that the teeth will operate successfully. `The beams G extend' back from the 'frame A in an oblique direction. The beams G areV made straight at the front ends, and extend back in a straight direction to near the middle, where they turn at an angle to correspond with the beams G. Inv the beams represented by G and G are secured any desired number of teeth, represented by e. H are bars secured to the rear end of the side pieces of the frame A, extending toward the centre to the rear of the frame, at'n'early right angles with the said side pieces of the frame A. At the inner ends of the bars H H are secured inclined braces, J J, which extend upward, and securedto the inclined posts I I. These posts, I I, are rigidly secured to the rear cross-piece of the frame A, and support the rear endofthe bar L, upon which is locked the adjustable drivers seat L. MM are also two inclined posts secured to the front end. ofl the frame A, which support the front end of the bar K. N N are two inclined foot-boards, the front ends of which are secured to a cross-bar, z', that is secured to theinclined posts M M. The rear ends of these foot-boards are secured to a crosspiece, m, that rests on the rear cross-piece of the frame, and secured to the posts I I. O is a lever, pivoted by' means of, a rock-shaft; the said shaft is provided with bearings secured to the inclined posts M M. The lower end of this lever, O, is bent in such a-manner as to form a hook, for the purpose of engaging in the eye-fn, that is located and secured to the upperside of the tongue or pole E, for the purpose of holding the harrow in an elevated position. The pole Eis secured to about the centre of the centre cross-piece D of the frame by means of a b'ifurcated bar or strap, P, that strides the said piece D, and a bolt that passes through the strap P and the cross-piece D, so as to form a pivot, upon which the pole works, and which holds the pole in its position. at2 is a guide; through which the pole or tongue passes, tolprevent any lateral-motion. The said guide is 'secured to the front cross-piece of the frame A1. Q is the evener, secured in the usual way upon the under side of the pole E by means of hammer and strap R. At

the rear ends of the two longer beams, G Gr, are secured cultivator blades or ploughs, SS, when it is designedy to use the machine for a marker for the rows of wrm-potatoes, 86e.

The operation is simple, easy, and perfect; each feature of the machine performs its functions `inthe most desirable manner. When it is only desired to vuse the roller the pole is rigidly engaged in the hook n, at the lower 'end of' the lever O, in the eye n. At the same time the seat is moved forward upon the bar K to a point where the weight of the driver will balance the harrow inl an elevated position, so that no part 'of the machine will operate except the rollers, as designed, the weight of the harrow, as also the driver, being upon the rollers.

When it is designed to use the combined machine, the hook upon the lever O is released from the eye n', in the pole, which allowsfthe harrow to resume its position upon the ground. When the driver adjusts his seat upon the bar K to any desired point, so as to bring his weight sufficiently upon the harrow to operate it to the proper depth in the ground, by moving or adjusting the seat upon the .bar K, regulates the depth of the teeth in the ground. l/Vhen it'is designed to roll, barrow, and mark o the rows for plants, the ploughs, S S, are placed in the rear end ot the two longer beams, GG. It' in this 'position the rows are too wide, by removing the harrowteeth and inserting the ploughs in their stead, the rows may b e varied as desired'. To roll and cultivate'among corn, the wheels B B are removed, which will allow the rollers, CIC, tomove from the centre to the outside of the frame, where they are secured, which leaves a space of from four yto twelve inches between the two sections of rollers. The movable piece T is then removed, together with-its tooth. The outer or rear ends of the beams G G are moved'ont from each other, and again secured tothe bars or stays H H. The front ends of the beams may also be moved apart in the same manner, upon the rear cross-timber of the frame A, when the machine will stride the rows, rolling and cultivating the ground and eradicating the weeds. When the plants have attained a suiei'ent growth tohave the dirt thrown upon the roots, the two inside or centre harrow teeth are removed and the ploughs S S used in their stead. To barrow and cultivate without rolling, the rollers are removed, and only the wheels B B employed to carry the machine, so that it will performall the functions of an ordinary hairow. At the same time a comfortable seat is provided for the driver, sothat the infirm or one that has lost a limb can operate it when hewould not be able to travell and drive the team.

Having thus secured my invention, lwhat I claim as new, and desire to securel by Letters Patent, is-

1. The employment of' the pivotedlever O, for the purpose of elevating the barrow so that only the rollers may be used, substantially as shown and described and for the purpose set forth. y

2. The wheels B B in combination with the-rollers C C and frame A, constructed and arranged in such a manner that Athe rollers may be removedl and only the wheels used, or the wheelsremoved and the rollers moved out to the frame, substantially as herein shown and describedA and for the purpose set forth. v

3. I also claim the beams G G, standingobliquely to tlie frame A, when the said frame A is provided with wheels B B and rollers C C, constructed and operated substantially and for the purposes set forth.

4, The adjustable seat in combination with the frame A, wheels A A, rollers C C and harrow, for the purpose of regulating the depth of the harrow teeth e, substantially as described and for the purposes set forth.

5. Attaehingthe pole or tongue E, by means ofbifurcated bar or' straps P, to near the centre cross-piece K of the frame A, in combination with the guide a2, substantially as shown and described and for the purposes set forth. I

GEORGE H. WOODRUFF.
