GEORGE J. CARPENTER, OF BRONSON, MICHIGAN.

LAND-ROLLER.

Specification of Letters Patent.

Patented Sept. 4, 1906.

Application filed June 16, 1906. Serial No. 822,087.

To all whom it may concern.-

Be it known that I, GEORGE J. CARPENTER, a citizen of the United States, residing at Bronson, in the county of Branch and State of Michigan, have invented a new and useful Land-Roller, of which the following is a speci fication.

This invention has relation to land-rollers and it consists in the novel construction and arrangement of parts as hereinafter shown and described.

The object of the invention is to provide a land-roller of substantial construction which may be easily turned to change its course or direction in traveling over the ground.

It consists, primarily, of parallel bars spaced apart and resting upon a pair of alined rollers, said rollers being in vertical alinement under the forward bar. A horizontal frame is superimposed upon said parallel bars and is provided with a forwardly-extending portion the central axis of which is substantially midway between the inner ends of the said alined rollers. A rectangular frame is pivoted at its middle at the central longitudinal axis of said forwardly-extending portion of the superimposed frame. The roller is journalcd in suitable bcarings carried by said rectangular frame. The rectangular frame is located substantially in advance of the said parallel bars that it may describe at least three-quarters of a turn without coming in contact or forcing its attachments in contact with the said bars. J ournal-bearing supports of suitable construction are provided and will be described hereinafter.

In the accompanying drawings, forming a part of this specification, Figure 1 is a top plan view of the roller. Fig. 2 is a vertical longitudinal sectional view of the same, and Fig. 3 is a perspective view of the roller-bearing support.

The roller consists of the parallel bars 1 1 and rollers 2 2, which are in alinement with each other and located vertically under the forward bar 1. The journal-bearing supports 3 depend from the forward bar 1 and will be described hereinafter. The bearings 4 are carried bythe supports 3 and receive the ends of the shaft 5 that passes longitudinally through the center of the roller 2. The braces 6 extend from the rear edges of the supports 3 to the rear bar 1. The frame 7 is superimposed upon the bars 1 1 and is attached to the same. Said frame is provided With the forwardly-extendmg portion 8, the

center axis of which is substantially midway between the inner ends of the rollers 2 2. The rectangular frame 9 is pivoted at its middle at the central axis of the forward portion S'of the said frame 7. The said frame 9 is provided with the cruciform-braces 10 at the point of intersection of which the king or pivot bolt 11 is located. The roller 2 similar to that heretofore described is attached in a suitable manner to the frame 9 and supports the same. The said frame 9 is provided with the hooks 12, which are adapted to receive and retain eyes carried by the cross-piece at the end of the tongue 13.

It is understood that the draft-animals (not shown) are attached to the said tongue.

The bearing-supports 3 are made from sheet metal. As they are of substantially the same construction a description of one will answer for all. The support consists of the vertical back wall 1 1, at the edges of which are located the parallel flanges 15 15, which extend in planes at right angles to the back wall 14. The upper ends of said flanges 1.5 terminate in the lugs 16, which are bolted or otherwise secured to the particular portion of the frame of the roller to which the bearingsupport is applied. The upper end 17 of the back wall 14 of the support is bent in at right angles to the said back wall between the flanges 15 15 and is also adapted to be secured to the under side of the particular portion of the frame of the roller to which the said support is applied. The bearing 4 is supported by the bolt 18, which passes through the side flanges 15 15 and also through the said bearing. It will thus be seen that the bearing-support is provided with special construction which although being constructed of sheet metal is so formed as to brace itself in all directions against the strains found in implements of this character. Also the bearings 4 may be easily and readily removed from the supports for repairs or substitution. It will also be observed that the square frame 9,-if detached from the tongue 13, may describe a complete revolution without interfering with the rear rollers 2 2 or other attaclnnents. However, when the tongue 13 is attached to the said frame 9 by reason of said attachment the frame 9 may describe but three-quarters of the rotation. The sweep of such an arc is all that is necessary in an implement of this kind to permit the same to turn freely and in short distances.

As shown in Fig. 3 of the drawings, the lugs 16 are not bent down at right angles to the flanges 15, but continue in the same vertical planes with the said flanges. the left shows-the method in which the bearing-supports are applied to the frame when the lugs 16 are in the same vertical planes as the flanges 15.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is I A land-roller consisting of a frame, a series of longitudinally-alined rollers supporting the rear end thereof, a frame pivotally attached to the forward end thereof, and a roller supporting the last said frame, said frame-supports comprising metallic sheets a Fig. 2 at i per ends of the back walls and extending behaving back walls, side flanges formed at the edges thereof and extending in planes at right angles thereto, bearings located between said flanges, flanges formed at the uptween the side flanges and attaching means securing the last said flanges to the frame of the roller, the upper ends of said side flanges terminating in lugs which are also attached to the frame of the roller.

In testimony that I clailn the foregoing as my own I have hereto afl'lxed my signature in the presence of two witnesses. v

GEORGE J. CARPENTER.
