r s rs Specification of Letters Patent.
Patented Feb. 6, 1906.
Application filed September 22, 1905. Serial No. 279,592. I
To all whom, it may concern.-
Be it known that I, WILEY J. DUNIIAM, a citizen of the United States of America, residing at Berea, in the county of Cuyahoga and. State of Ohio, have invented certain new and useful Improvements in Land-Rollers; and I hereby 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 pertains to make and use the same.
This invention relates to improvements in. land-rollers.
The object of this invention is to provide a machine of this character having the rollers mounted so that they can move independently in order that they may readily aceom modate themselves to the condition of the land. over which the machine is passing, and thereby prevent the machine from being illjured by undue strain.
My invention therefore consists in the features of construction and. combination of parts as described in the specification, pointed out in the claims, and illustrated in the drawings.
In the accompanying drawings, Figure 1 is a front elevation of a machine embodying my invention as it appears when traveling over level land. Fig. 2 is a front elevation showing the position assumed by the rollers when passing over an elevation. Fig. 3 is a top plan with the yoke which connects the side pieces of the draft-frame broken away. Fig. 4: is a section on line 4 4, Fig. 1.
As shown in the drawings, the machine comprises two independent rollers, each of which consists of two sections 1. and 2, which are rigidly mounted on a shaft or axle 3, so as to leave a small space between the adjacent ends of the sections. Around each of the sections 2 of each of the rollers is arranged a rec-' tangular frame 4. Above the f 'ame 4 is arranged the draft-frame, which comprises two side pieces 5, preferably formed of angle-iron. The side pieces 5 are secured together by means of a cross-piece or yoke 6, one end of which is fastened at the center of each of said side pieces. A bracket 7 is arranged at each end. of each of the side pieces 6, so as to ex tend downwardly therefrom, and in said. bracket 7 is formed a horizontal slot 8. The draft-frame is supported on the frames 4 by means of arms or trunnions 9, which extend out from the front and back of said frames near the outer sides thereof and enter the slots Sin the brackets 7. Heads 10 are pref erably formed on the ends of the said trunnions 9 in order to prevent the brackets from slipping oil the ends thereof. A depending arm llis arranged at each side of the center of each side piece 5. At the front and back near the inner end of each of the frames at is secured one end of a link 12, and the other end thereof is secured to the adjacent arm. 11, and. the arrangement is such that when the roller-sections lie .in the same plane the said links will be in a horizontal position. To one of the side pieces 5 of the draft-frame is secured a draft-bar 15, and on the other side piece 5 is mounted a seat 16.
The operation of the land-roller is as follows: When the roller is traveling over level ground, the lLTLlIlliiOllS 9 will be about in the center of the slots 8 and the links 11 lie in a horizontal position and the inner ends of the roller-sections will be close together. If the roller is dragged over some unevenness which raises the roller-sections at their inner ends, as shown in Fig. 2 of the drawings, the draftframe will remain horizontal, and as the inner ends of the roller-sections are raised the links will describe an arc of a circle, drawing the respective roller-sections away from each other at their inner ends and causing the trunnions to move out in the respective slots 8.
What I claim is- 1. In a land-roller, the combination of rollers, each roller having a separate shaft, a frame mounted on each of said shafts of said rollers, a draft-frame, means for forming a slidable connection between the frames of said rollers and said draift-frame and means for mechanically causing said rollers to move apart when either or both of the rollers are moved. out of a horizontal position.
2. In a land-roller, the combination of rollers, each roller having a separate and independent shaft, a frame mounted on each of said shafts of said rollers, a draft-frame, means for forming a slidable connection between saidv frames of said rollers and said draftframe and links securin the inner ends of said. frames of said rollers to said draftframe.
3. In a land-roller, the combination of rollers, each roller having a separate shaft, a frame mounted on each of said shafts, a draftframe, means for forming a slidable connection between said roller -frames and said draft frame, arms secured to said. draftframe and links connecting said arms and said roller-frames.
4. In a land-roller, the combination of rollers, each roller having a separate shaft, a frame mounted on each of said shafts, a draftframe comprising two side pieces arranged to extend longitudinally of said rollers and a cross-bar secured to said side pieces at their centers, and means for mounting said draftframe on said roller-frames.
5. In a land-roller, the combination of a plurality of rollers, each roller having a separate shaft, a frame mounted on each of said shafts, a draft-frame arranged above said roller-frames, said draft-frame comprising two side pieces secured together by means of a cross-bar fastened to the respective side pieces near their centers, means for forming a slidable connection between said draftframe and said roller-frames and links secured to said draft-frame and to said roller- 20 frames.
6. In a land-roller, the combination of rollers, each roller having a separate shaft, a rectangular frame mounted on each of said shafts, trunnions formed at the front and back of said frames at the outer ends thereof, a draft-frame, arms arranged on said draftframe at the outer ends thereof and provided with slots arranged to receive said trunnions on said roller-frames, arms arranged on said draft-frame near the center thereof and links connecting said last-mentioned arms and the inner ends of said roller-frames, substantially as described and for the purpose set forth.
I11 testimony whereof I sign the foregoing specification in the presence of two witnesses.
