LAND-ROLLER.

SPECIFICATION forming part of Letters Patent No. 757,583, dated April 19, 1904.

Application filed March 28, 1903. Serial No- 150,04l. (No model.)

To all whom it may concern:

Be it known that 1, ROBERT V. WALLACE, a citizen of the United States, residing at Alki, in the county ofWhitman and State of Washington, have invented a new and useful Land- Roller, of which the following is a specifica-' tion.

This invention relates to land-rollers, and has for its Object to simplify and improve devices of this character and reduce the expense of manufacture without decreasing the efiiciency or lessening the capacity; and the invention consists in certain novel features of construction, as hereinafter shown and de scribed, and specified in the claims.

In the drawings illustrative. of the invention, in which corresponding parts are denoted by like designating characters, Figure 1 is a plan view. Fig. 2 is a front elevationof the device complete.

The draft-tongue, which is represented at 10, is. of the usual form and extends rearwardly over the framework supporting the rollers.

The roller-frames are represented, respectively, at 11 12 and are oblong in shape and of wood or metal, but preferably of metal, and will be disposed with their adjacent ends beneath the tongue and provided with perforated cars 13, between which corresponding perforated lugs 14, extending from the tongue, are movably connected by pintles 15, this construction forming independent hinge connections between the frames and tongue. The lugs 14 are integral with a plate 16, attached beneath the tongue, as by bolts or rivets, and the plate at the rear end ofthe tongue is provided with an eye 17, extending beyond the tongue, as shown, to provide means for the coupling ofa trailer-roller frame, as hereinafter explained.

The main rollers are indicated, respectively, at 18 19 and mounted for rotation upon the frames 11 12 by journals 20 21, operating in bearings 22 23, depending from the frames, as represented.

.The frames 11 12 are provided with forwardly-extended portions 24 25, upon which the forward series of the lugs 13 are carried,

as shown, by which means the distance between the lugs is increased and the weight of the frames and rollers more uniformly balanced and the draft thereby improved.

Extending from the frame 11 is a seatbracket 26, and extending from the frame 12 is asimilar bracket 27. Attached by one end, as by a bolt or rivet 28, to the bracket 26 is a seat-base 29, carrying the seat and with the other end engaged movably by bracket 27 and operating beneath a guide-strap 31 thereon, as shown. The guide-strap 31 is sufiiciently large to permit a slight vertical movement of the free end of the seat-base 29 within the same, so that the seat 30 will not be affected by the movements of the roller-frames, but will retain its proper position under all their varying changes of position.

Attached to the

extensions

24 and 25 of the chain 34' engages, the ends of the chain supporting the swingletrees 35 36, as shown. The chain-pulleys will be spaced apart to correspond to the distance between the centers of the swingletrees for obvious reasons.

The trailer-roller frame is represented at 37 and will be formed of the same material as the frames 11 12 and will rotatively support the trailer-roller 38 by its journals 39, as shown. The frame 37 is connected to the eye 17 of the rear plate 16 by a clevis 41 and limbpin 42, so that the frame will freely trail? behind the frames 11 12 when in operation and may be readily detached and attached when required.

4 The three roller-carrying

frames

11, 12, and 37 being pivoted at their inner ends to a common support render the rollers free to adapt themselves to the irregularities-of the surface of the ground.

Having thus described my invention, what I claim is- 1. In a land-roller, a draft-tongue, apivotal connection between the rear ends of the frames and the'draft-tongue, a painof frames provided with forwardly and inwardly extending supporting-arms hingedly connected to the tongue, rollers mounted for rotation in said frames, a trailer-frame flexibly connected to the rear end of the tongue and having a roller frames are chain-pulleys 32 33, with which a journaled therein and a pair of draft-pulleys mounted for rotation respectively upon the supporting-arms.

2. In a land-roller, a draft-tongue, frames flexibly connected at their adjacent ends to opposite sides of the tongue, rollers mounted for rotation in said frames, seat-brackets secured to the frame and extending above the rollers, one of said brackets being provided with a guide-strap, and a seat-base connected at one end to one of the brackets and having its opposite end passing through said guidestrap and vertically movable therein.

3. In a land-roller, a draft-tongue, frames provided with forwardly and inwardly extending arms flexibly connected to opposite sides of said tongue, a pivotal connection between the rear ends of the frames and the draft-tongue,

ROBERT V. WALLACE.
