LAND-RCLLERQ SPECIFICATION forming part of Letters Patent No. 337,577, dated March 9, 1886.

' Application filed October 29, 1885. serial No. 181,296. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH HAFNER, of Fowler,,in the county of Clinton and State of Michigan, have invented a new and Improved Land-Roller, of which the following is afull, clear, and exact description.

My invention relates tomachines adapted especially for rolling land to crushlumps left by the harrow and bed the seed,but adapted, also, for rolling lawns orleveling and rolling roads; and the invention has for its object to provide a simple, inexpensive, effective, and durable machine of this class.

The invention consists in certain novel features of construction and combinations of parts of the land-roller, all as hereinafter fully set forth.

Reference is tobe had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is an under side view of the landroller with the draft tongue broken away. Fig. 2 is a rear view of the machine, and Fig. 3 is a side elevation of the machine with the tongue broken away and the double tree in cross-section.

The two rollers A A of the machine are journaled each at its outer end in an eye, b, of a hanger, B,which is branched or forked at its-forward part into two arms, 12 I), each of which is pivoted to an eyebolt, O, fastened in the main cross beam or timber D of the machine-frame. The inner end of each of the rollers is journaled in an eye, 6, of a hanger or arm, E, which is longer than hanger B, and the forward ends of both the hangers EE are pivoted to an eyebolt, F, which is fastened in the tongue G of the machine, said tongue being fixed at its back end to the cross-beam D, and also braced to the beam by bars or plates H H, one at each side of the tongue, asshown.

Draft may be applied to the machine by hitching the animals to a double-tree or evener, I, held to the tongue G by a bolt passed through the hammer-strap 2' into the tongue, or otherwise.

The drivers seat J is fixed to the upper end of a flexible or elastic arm or standard, K, which is forked at its lower part to form arms k k, which pass down one at each side of the tongue G, and are connected at the ends by a cross-bar, k, which bears against the under side of the tongue, while the lower edges or faces of the arms k or of wear-plates is, fast-. ened thereto, bear on the top of the main beam D. The arm K has a cross-bar, k which projects at both sides to formfoot-rests for the driver when he is in his seat. The seat J may be shifted backward or forward by slipping its flexible standard K along the tongue, and as will be understood from the dotted lines in Fig. 3, and whereby the weight of the driver may be made to balance the tongue and take its weight from the horses necks, and whereby also the entire weight of the machineframe will be thrown onto the rollers.

Metal plates L are fixed to the under side of the beam D, on which plates the rollers hangers B E rest, as shown in Figs. 1 and 3, to protect the beam from wear.

It is evident that as the machine is drawn over the land the rollers A'A will adjust themselves to the groundsurface independently of each other, and when the rollers take positions out of line and highest at their inner ends, as shown in full lines in Fig. 2, the entire weight of the machine-frame and the attendant will be borne by the center hangers, E E, and when the rollers are highestat their outer ends, as indicated by the lower dotted lines :20 :0, Fig. 2, the entire weight of theframe and attendant will fall on the outside hangers, B; hence the weight on the rollers is most effective where the land is highest or thelumps are largest, and the best results in smoothing the land are secured.

By connecting the longer central rollerhangers, E, to the frame forward of the main beam D, or of the point of connection of the outside hangers, B, with the beam or frame, the inner ends of the rollers will more quickly lift the frame as said ends rise over lumps or high ground directly under the driver or attendant, and there also will be less tendency of the superineumbent weight to wrench or twist the hangers from the frame than would be the case if the hangers B E were of like length and were all connected to the beam D in line crosswise of the machine, as the dis- 10o tance from the eye F to the wearplate L affords a largely increased leverage or resistance to the hangers E over that given the hangers B, connected to the eyebolts O.

The rollers may be made solid or hollow and of wood or metal, as the particular use to which the machine is to be put may require.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A land-roller constructed with two roll ers jourualed in outer and inner hangers pivoted to the machine-frame, and on which hangers the frame is adapted to rest, and said inner hangers being longer than the outer hangers and connected to the frame in front of the points of connection of the outer hangers therewith, substantially as herein set forth.

2. A land-roller comprising rollers A A,

journaled in hangers B B, pivoted to the ma chine-frame, and hangers E E, pivoted to the frame by an eyebolt, F, placed forward of the pivoted connection of the hangers B with the frame, and said hangers B E being adapted to support the frame on the axles of the rollers, substantially as herein set forth.

3. The combination, in a land-roller, of the cross-beam D, tongue G, hangers B E, pivoted to the beam and tongue, respectively, and rollers A A, journaled in the hangers, substantially as herein set forth.
