LAND-ROLLER.

SPECIFICATION forming part of Letters Patent No. 681,297, dated August 27, 1901.

Application filed January 11, 1900. Renewed January 10, 1901. Serial No. 42,814- (No model.)

T0 at whom it may concern:

Be it known that I, FREDRICK A. BRUOK- MAN, a citizen of the United States, residing at Plainview, in the county of Linn and State of Oregon,have invented certain new and use ful Improvements in Land-Rollers; and I do 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.

The invention relates to improvements in land-rollers.

The object of the invention is to provide a machine of this character which shall be simple of construction, durable in use, comparatively inexpensive of production, and which shall be efficient in operation.

To this end the invention consists in certain features of construction and combination of parts, which will be hereinafter fully described and claimed.

In the accompanying drawings, Figure l is a perspective view of my improved land-roller. Fig. 2 is a vertical sectional view through the front cross-piece of the frame, illustrating the manner of connecting one of the front rollers thereto. Fig. 3 is asimilar View through the rear cross piece, illustrating the manner of connecting the rear roller thereto.

In the drawings the same reference characters indicate the same parts of the invention.

1 denotes the main frame, and 2 the tongue. The main frame comprises the forward crosspiece 3 and the rear cross-piece 4, connected together by said tongue and by a weight-receiving box 5.

6 denotes forward diagonal braces the forward ends of which are bolted to the tongue and the rear ends of which are bolted to the under side of the forward cross-piece 3 and are formed with downwardly-extending lugs 7.

8 denotes the forward landrollers, and 9 the yoke-frames in which they are journaled. The forward ends of the yoke-frames are secured to castings 10 by bolts 11,and these castings 10 are formed with apertures 12 to receive the studs 7 of the braces 6.

Cotter-pins or other fastening devices are secured to the lower ends of the studs and hold the yoke frames in place. The side pieces of each yoke frame are connected to gether at their rear ends by bars 13, which are pivotally connected to the outer ends of the rear cross-piece 4 by links 14.

15 denotes the rear land -roller, which is journaled in the yoke-frame 16,supporting the weight -receiving box 17, which is bolted in advance of the roller 15 to the side pieces of the yoke-frame.

18 denotes a hook-plate secured to the upper side of the tongue at its rear end by bolts 19 and 20, the former passing through the plate and the tongue and the latter through the plate, tongue, and rear cross-piece 4.

21 denotes a casting to which the forward end of the yoke-frame 16 is bolted. This casting is provided With an aperture 22 to receive the rear end of the hook-plate 18, which is'provided with a cotter-pin or other fastenin g 23 to hold the rear yoke-frame in position.

In operation the boxes 5 and 17 are filled with stones to obtain the desired weight. As the machine is drawn along the forward landrollers 8 will have a wabbling movement to accommodate themselves to the variations of the ground, and so will the rear roller. In addition to this movement the rear roller may swing at various angles to the forward rollers in turning corners.

From the foregoing description, taken in connection with the accompanying drawings, the construction, operation, and advantages of my improved land-roller will be readily apparent without requiring an extended expla nation. It will be seen that the device is simple of construction, that said construction permits of its manufacture at small cost, and that itis exceedingly well adapted for the purpose for which it is designed, and it will of course be understood that various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

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

In a land-roller, the combination with the drafttongue; of the forward and rearward cross-bars secured thereto, the diagonal forward cross braces secured at their forward ends to the tongue and at their rear ends to the forward cross bar and provided with downwardly-extending lugs, a hook-plate secured to the rear end of the tongue and provided with an upwai dly-extending lug, two aiined land-rollers and a trailing rear roller, yokeframes in which the land-rollers are journaled, 5 castings having apertures to receive the aforesaid lugs, fastening means secured to said lugs, bolts connecting said castings with the yoke-frames, bars connecting the rear ends of the forward yoke-frames, and links connecting the bars to the rear cross bar; snbstan- IO tially as and for the purpose set*forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit- IIGSSGS.

F. A. BRUOKMAN. Witnesses:
