Description

UNITED STATES PATENT OFFICE.
j BYRON D. TABOB, OF WILSON, NET YORK, ASSIGNOR TO HIMSELF AND CLINTON D. TABOB, OF SAME PLAGE.
|MPRovEMENT IN FIELD-Romans.
Specification forming part of Letters Patent No. 150,629, dated May 5, 1874 application filed March 4, 1874.
The nature of my invention consists in the construction and arrangement of a land or field roller, as will be hereinafter. more fully set forth. V
In order to enable others skilled in theart to which my invention 'appertains to make and use the same, I will now proceed to Vdescribe its construction and operation, referring to theY annexed drawing, in which- Figure l is a plan view, Fig. 2 a vertical section, Fig. 3 a section, of the roller, showing the construction; Fig. 4, a plan of the journal-- boxes; and Fig. 5 a plan of the journal.
vA A represent two side timbers of the frame, on the top of which, and crossing from one to the other, are bolted threeV planks, B B. To the under side of the two front pieces is secured the tongue C.
The rollers are constructed as follows: Each roller has two cast heads, D D, in the inner side of each of which is made an annular groove or channel, a, near the outer edge, for the reception of the wooden staves E E. These staves have their ends cut to t the channel and fill in between the two heads. Bolts b b are then passed through, holding the heads firmly to the ends of the staves. The outer head of each roller has a large bore cast in its hub, into which the journal d fits loosely, and is fastened securely to the inner side by three bolts passing through corresponding projections on the hubs of the journal and head. These journals run loosely in boxes L h, which consist simply of a cored casting provided with trunnions z' i, which have their bearings in eyebolts e e passing upthrough the timbers AA. This arrangement allows a free play of the inner ends of the rollers up and down, by which means they can conform to the surface of the ground.
The sections or rollers are keptfrom sliding together endwise by means of suitable washers placed onthe ends of the journals and held to place by nuts screwed on bolts cast in the ends of the journals. The center joint between the two rollers consists simply of a thimble, f, bolted into the bore of one of the inner or center heads in the same manner as the journal. In the opposite head is bolted a journal, m,
having a ball, a, riveted on its outer end. This ball moves freely in the thimble, making a free working joint. Y
b2 is a hook or keeper linked into staple e2, with its opposite endfitting over the journal which is on the inner ends of the rollers.
Having thus fully described my invention, what I claim as new, and desire lto secure by Letters Patent, isl The combination, with the two sections of a field-roller, of the keeper b2, thimble f, and the journal m, with a ball, n, on its end to form a flexible joint between the two sections, substantially as herein set forth.
In testimony that I cla-im the foregoing as my own invention I affix my signature in presence of two witnesses.
BYRON D. TABOR.
