ALBERT G. BARTON, ()F "IIREE RIVERS, MICHIGAN.

FIELD-ROLLER.

SPECIFICATION forming part of Letters Patent No. 406,078, dated July 2, 1889.

Application filed August 4, 1888. Serial No. 281,972. (No model.)

To all whom it may concern:

Be it known that I, ALBERT G. BARTON, of Three Rivers, in the county of St. Joseph and State of Michigan, have invented anew and useful Improvement in Field-Rollers; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

M y invention relates to landrollers of that kind where a main supporting-frame is employed, having tie-bars which reach through the front and rear beams, and which are provided with eyes on their front ends, to which a draft-bow is attached. bound frame are two independent oscillating frames, and to the main frame is a draft beam or tongue attached by V-shaped braces.

Now, the nature of my invention consists in a novel mode of attaching the front and rear journals or trunnions of the inside oscillating auxiliary frame to the main frame, reference being had to the annexed drawings, in which Figure 1 is a perspective view of a landroller, showing my improvement applied-to it. Fig. 2 is a plan view of the same. Fig. 3 is a longitudinal section showing a drag applied to the main frame. Fig. 4 isa perspective view showing a drag having curved teeth adapted to gently skim over the crushed clods and to even the same, the bar to which the drag-teeth are applied being sufficient to effect the object which I have in view.

Iteferringto the annexed drawings, A designates the main rigid frame; 13, tie-bolts extending through the rear piece a and the front piece a of the said frame. These bolts have eyes I) on their front ends, to which is shackeled a draft-bow 0, having a center draft-loop c in the middle of its length. It will thus be seen that I draw from the posterior beam to. In addition to these tie-bars, I employ invertcd-V-shaped braces G, bolted rigidly to the front and rear beams to a, and on top of these braces G, I rigidly secure a draft-tongue F, on which is the drivers seat, as shown in Fig. 1.

Inside of the main frame A are two rollerframes E E, bearing the gudgeons of the Inside of this tie-' rollers D, which may be constructed in any suitable manner. Each inside roller-frame E is provided centrally, fore and aft, with a bearing-plate 1?,whichis a rc-enforcing piece, and which is perforated to receive a hooked boltj". This hooked bolt f is intended to form a part of the bearing-plate (Z and a journalconnection for the trunnions e. These trunnions c are rigidly bolted to the front and icartransversc beams of the main frame, and are received between the hooked ends of the boltsf and the plates (7. It will thus be observed that the inside frames are free to articulate not only about their lateral axes, but that they are also free to articulate about their longitudinal axes. In short, they are hung on a gimbal. By these means it is obvious that the front and rear joints can be adjusted at will, so that the lateral oscillation of each roller-frame is not impeded, or, if by reason of a collection of mud the parts become clogged, the nut on the lower end of the hooked retainers can be loosened, thereby relieving the same.

By reference to Figs. 1, 3, and 4, itwill be seen that I employ a hinged drag, which is designed to supersede the old-fashioned bush.

It is attached to the frame of the field-roller by means of rods g 9, having eyes in their lower ends, as indicated in Fig. 4. The bar J is provided with teeth i, having hooked ends, and it is free to articulate and skim lightly over the crushed ground in rear of the rollers D, for the purpose of lightly harrowing the surface soil.

Ilavin g described my invention, whatI claim as new, and desire to secure by Letters Patent, 1s-

In a field-roller of the character described, the combination, with the frame of the machine, of the bar hung therefrom by eycbolts and provided with hook-pointed scratchingteeth, substantially as specified.

In tcstim ony whereof I aflix my signature in presence of two witnesses.

ALBERT G. BARTON.
