LAN D-ROLLER.

SPECIFICATION forming part of Letters Patent N o. 407,520, dated July 23, 1.889.

Application filed September 5, 1888. Serial No. 284,603. (No model.)

mounted on Wheels and provided with pivoted arms, each universally connected with. a frame carrying a land-roller.

The invention also consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forminga part of this specification,

in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is aplan View of the improvement y as applied in the iield. Fig. 2 is a like view of the same, showing the several rollers placed one behind the other. Fig. 3 is a front elevation of the same with the rollers and tongue removed. Fig. 4 is a side elevation, with parts in section, of the improvement. Fig. 5 is a side View of the wheel-bearing. Fig. G is a sectional front elevation of the same. Fig. 7 is an enlarged plan view of the universal joint connecting the roller-frame with a pivoted arm. Fig. 8 is a sectional side elevation of the same. Fig. 9 is a side elevation of the bolt used on the universal joint. Fig. l0 is a plan View of part of-the frame. Fig. ll is an end elevation of one of the rollers. Fig. 12 is a longitudinal sect-ion of the same, and Fig. 13 is a side view of a modified form ofone of the rollers.

The' improved land-roller is provided with a sectional frame A, consisting, principally, of a front beam A', to which is pivotally con- 2 nected, in the usual manner, the tongue B.

From the rear ofthe front beam A' extend the beams C C' and D D', connected with each other by the cross-beam E and the brace E', slightly curved in ,its middle, as shown in Figs. 3 and 4. Between the beams C C and. the

beams D D are mounted thewheels F and F', and on the transverse beam E is mounted the wheel G, said three wheels F, F', and G supporting the main frame A.

The wheels F and F' are mounted vertically adjustablein bearingsl F2 and F2, secured on the respective beams C C' or D D'. Each of the bearings F2 and F2 is provided with a vertical slot F4, through which passes a shaft F5, carrying the Wheels F or F'. On the shaft F5 is secured a gear-wheel F5, meshing into a rack F7, formed on the bearing F2, and the said shaft F5 is fastened to the bearings at any desired height by a nut F8, screwing on the outer threaded end of the said shaft F5 against the bearing F2, as plainly illustrated in Figs. 5 and 6. Thus by loosening the nut F8 the wheels F and F' can be raised or lowered, so that the frame A is adjusted to any desired height. The nut F8 is then screwed up,so as to fasten the shaft F5 to the bearings F2 and F2.

The rear wheel G is connected with the transverse beam Ein such amanner that when the frame A is raised or lowered t-he connection of the wheel with the frame adjusts itself. Said wheel G is mounted for this purpose in the forked frame G', pivotally connected with the U-shaped arm G2, held vertically and passed loosely at its middle portion through a holder G2, secured tothe rear of the transverse beam E, as is plainly shown in Fig. 4. Thus when the frame A is raised and lowered said holder G3 slides up or down on the middle'portion of the U-shaped arm G2.

Near the front end of the beams C and D are pivoted the L-shaped brackets H and H', respectively, adapted to be locked in place on the frame A by a spring-lever H2, pivoted on top of the front beam A'. On the outwardlyextending arms of the brackets H and H', respectively, are pivoted the beams I and I', each pivotally connected by bolt I2 with a clevis J, adapted to be locked in place by a bolt I5, passing through the said clevis and either of the arms I4 and I5, formed at right angles to each other on the end of the beamI or I spective beam I or I'. One end of the clevis .I is connected by the adjustable chain K with the tongue B. On each clevis .I is formed a vertical aperture, through which passes a rod L, held in any desired place in the clevis G by The arm I1 extends in line with the rev IOO a set-screw L'. On the lower end of the rod L is mounted to rotate a wheel L2, as plainly shown in Figs. 3 and 4.

On the clevis J is formed afork J ',between the arms of which is held adiskN' of the link N, said disk being pivotcd on the said fork by means of a bolt J2, passing through the fork and the said disk N', and provided at-its lower end with offsets J3, which pass through corresponding slots J 4, formed in the plates of the fork J', as shown in Figs. 7 and S. When the bolt J2 is inserted through the fork J' and the disk N', said bolt is turned, whereby the proj ections J 3 engage the under side of the fork J', and thus prevent the bolt J2 from becoming detached from the said fork. A spring may be employed to hold said bolt J2 in place after being turned.

The link N turns horizontally on the clevis J, and on the said link N is pivoted another link O, mounted to swing up and down on the said link N and carrying a bolt O', on which is secured a U-shaped frame P, in which is mounted to turn a roller Q or Q. The frame P of the roller Q or Q' is thus universally jointed by means of the links N and O to the clevis J, whereby the roller Q or Q' can swing sidewisc and pass over uneven ground independently of the main frame A.

To the rear of the cross-beam E of the main frame A are pivoted the beams R and R', each provided at its outer end with a clevis J, of the same construction as the one above referred to in reference to the beams I and I'. The arm R can be lengthened whenever desired, as illustrated in Fig. l0. The clevises J on the beams R and R are connected by adjustable chains S and S', respectively, with the side beams C and D of the frame A, as is plainly shown in Fig. l. Each of the said clevises J of the beams R and R is also universally jointed to frames P, carrying the rollers Q2 Q3. The same links N and O, as above described, connect the said frames to the said clips.

In the space formed by the frame A is held a roller Q2, mounted to turn in a frame P, universally jointed by links O and N to a clip secured to the middle of the front beam A'. rlhe side beams C and D is also connected by adjustable chains U and U' with the beams I and I', respectively.

Each of the rollers Q, Q', Q2, Q3, and QL is preferably made as illustrated in Figs. ll 'and 12, in which the rim Q5 is formed of sheet metal and is secured to disk-heads Q, made in sections and supported by spokes Q7, proj ecting from the hub Q3. The sheet-metal covering of the rollers is preferably spirally arranged, as shown in Fig. 13.

The operation is as follows: Vhen the landroller is in the position shown in Fig. l. and is moved forward in the direction of the arrow a', the five rollers Q, Q', Q2, Q3, and Q4 are arranged so that all the space of the field between the outer ends of the rollers Q and Q is rolled, the space between the rollers Q and Q4 and Q' and Q4 being rolled by the rear rollers Q2 and Q3. The universal joint on each of the rollers permits a sidewisc or up-anddown movement of the said rollers independently of the main trame A and the tongue B. Then the operator desires to move the landroller from place to place over roads, fields, &c., the arrangement shown in Fig. l would take up too wide a space, and the operator then disconnects the chains K K', S S', and U and U' from their respective beams. The beams R and R' then swing rearward andthe arm R is lengthened out, as is plainly shown in Fig. 2. The corresponding rollers Q2 and Q3 of the said beams R and R' then assume the position shown in said Fig. 2-that is, one directly behind the other and to one side. The beams I and I' also swing rearwardly and inwardly, and the rollers Q and Q are directly behind the cross-beam E and in front of the rollers Q2 and Q3, respectively. The universal joints by which the several frames are connected with their respective beams I I and R R' adjust themselves so that the several rollers assume the relative position to the main frame shown in said Fig. 2. The pin I3, locking the clevis J to the arm I4, is withdrawn and passed through the other arm I5 of the said clevis, as plainly shown in Fig. 2. It will be seen that the several rollers take up very little space in width.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patentl. In a land-roller, the combination, with a main frame, of beams pivoted to said frame, and the clevises for connecting the beams and main frame, the clevises carried at the free end of the beams and connected with the roller-carrying frame, substantially as shown and described.

2. The combination, with the main trame consisting of the beam A E and cross-beams C C D D', of the slotted vertical bearings F2 F3, secured, respectively, to the cross-beams C' D' and C D, the bearings F3 being provided with racks, the wheels F F', carried between the slotted bearings, shafts F5, carrying said wheels and provided with pinion F6 upon their outer ends and adapted to engage with the racks F7, and the nut F2, for holding the shaft securely between the slotted bearings, substantially as shown and described.

3. In a land-roller, the combination, with a main frame and a roller universally jointed on the said frame, of beams pivotally connected with the said main frame, a universal joint connected with each pivoted beam, a frame held on the said universal joint, and a roller supported on the said frame, substantially as shown and described.

4. In a land-roller, the combination, with wheels and a main frame held vertically adj ustable on the axis of the said wheels, of beams pivoted on the said main frame, a clevis held on the free end of each beam, a universal joint connected with the said clevis,
