"Eatented July 31, 1906;

Application filed March i9, 190e. serial No. 306,804..

To all whom it may concern: g

Beit known that I, SYLvEsTER WARNER, a citizen ofthe United States, and a resident of West Union, in the county of Parke and State of Indiana, have invented a new and Improved Land-Roller, of which the following is a full, clear, and exact description.

The purpose of the invention is to provide a roller especially adapted for rolling listed corn, being capable of operating upon two or more listed ridges.V

A further purpose of the invention is to provide rollers especially adapted to the shape of the ridges and which will not only roll the top or crown of a ridge, but will also crush the earth at the side edges, where it is most needed.

Another purpose of the invention is to .construct the rollers with an outer section independent of the body-section and slidable thereon, so that said outer sections by their movement upon the main sections will accommodate themselves to variations in the width of the ridges and also to provide tensioncontrolled regulating devices for the outer sections of the rollers which will overcome their tendency to crowd outward to compel ythem to act upon the edges of the ridges over which they pass.

Another purpose of the invention is to provide means for regulating the action of the controlling device upon the outer sections of the rollers, so that any needed tension can be obtained and so that the same pressure may be secured at all times on the outer sections ofthe rollers, thus preventing them climbing up upon the ridges when they reach their Wide faces.

A further purpose of the invention is to provide simple and convenient means for y adjusting the rollers bodily upon their supports to accommodate them to diiferentsized furrows made by different-sized listers.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, formin a part of this specification, in which simi ar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of the improved roller, a part of the frame being brokenaway. Fig. 2 is a vertical longitudinal section taken on the line 2 2 of Fig. 1. Fig. 3 is a rear elevation of the improved roller. Fig. 4 is a horizontal section taken through a portion of the frame and a sectional plan vi ew of one of the tension-equalizing members, drawn upon an enlarged scale. Fig..5 is a transverse section taken substantially on .the line 5 5 o f Fig. 1 and drawn also upon an enlarged scale, and Fig. 6 is an enlarged transverse ection taken substantially .on the line 6 6 of represents the frame of the machine said frame being of skeleton construction, comprising a front beam 10, a parallel rear beam 1 1, and end beams 12, together witha central transverse beam 13, to which latter beam the pole 14 is secured, fitted with any suitable draft device A. A shaft 1.5 extends from end to end of the frame, being passed through the `central beam 13, and this shaft is held stationary in the frame in any .approved manner-for example, by passing .a cotter-pin 16 through .one `of its ends or through both of its ends and the frame, if required.

B represents the rollers, which are mounted to turn on the shaft '15. These rollers are of spool shape, and each consists of a cylindrical body-section 17,"an inner conical headsection 18, secured to or integral with the body-section, and an outer conical opposing head-section 19, which outer sections 19 are free to slide to a limited extent on the bodysections 17 of the rollers, .as is shown best in Fig. 2. These outer head-sections 1.9 are preferably provided with apertures 20, so as to render them more or less light, and are yfurther provided at their hub or central portions each with a sleeve 21, and these sleeves .are loosely mounted on the fixed shaft 15 andextend into chambers 22 produced in the outer end portions of the body-sections 17 of the rollers, as is 4also shown in Fig. 2. By thus constructing the rollers B they are enabled to accommodate themselves automatically to variations inthe widths of the ridges, andthe peculiar shape of the rollers enables them when traveling over ridges to crush earth at IOO the sides of the ridges as well as at the top or l crown of the ridges.

The fixed shaft 15 is provided with series of apertures 23 at each side of its center, and these apertures receive pins 24, which have bearing against washers 25, located between them and the opposing inner end portions of the rollers, so that by changing the position of the pins on the shaft 15 the rollersB may IOS IIO

' tral portion of the frame.

be made to lie more or less closely to the cen- Sleeves 26 are loosely mounted on the end portions of the fixed shaft 15, and these sleeves 26 engage with the outer end portions of the sliding outer end sections 19 of the rollers, and in connection with these outer end sections 19 combined regulating and tensioning mechanisms C r are employed, applied through the medium of levers 27, the said levers being pivoted at their forward ends in the forward corner portions of the frames by' pins 28 or their equivalents, and the rear ends of the said levers extend out through slots or openings 30 in corresponding portions of the rear member 11 of the frame, as is shown in Figs. 1 and 3, and each of the levers 27 is provided with an elongated opening 29 between its ends, through which openings the shaft 15 passes.

The regulating and tensioning mechanism C is as follows: An opening 31 is made in the rear member 11 of the frame lat each side of the center of said member, as is shown in Fig. 3, and a pivot bolt or pin 32 is passed vertically through each of said openings 31. A peripherally- `rooved pulley 33 is eccentrically and loose ymounted on the said pin, as is 4 best shown in Fig. 4, and a smaller periphr also best shown in Fig. 4.

erally-grooved pulley 34 is attached to or formed integral with the upper face of each eccentric pulley 33. The smaller pulleys are concentric with relation to the bolts 32, as is Chains 35 are secured to the periphery of the eccentric pulleys 33, and these chains 35 are carried outward and are secured to the outer rear ends of the levers 27 by means of suitable eyes 36 or their equivalents. Chains 37 are attached to the periphery of the concentric pulleys 34, winding thereon in a contrary direction to the winding of the chains on the eccentric pulleys. The chains 37 from the concentric pulleys 34 are carried toward the center of the said rear member 1 1 of the frame and are attached to a post 38, mounted to turn in brackets 39, extending out from the top and bottom portions of the said rear member 11 of the frame, as shown in Figs. 3 and 5. This post 38 is provided with a polygonal head 40, so that it can be readily turned with a wrench 0r like tool, and at its upper portion, above the upper bracket 39, a disk 41 is secured to or made integral with the post, said disk having any desired number of apertures 42 therein, through which apertures a pin 43 is passed into the frame to hold the post in the position in which it may be set, and each chain 37 between its ends is provided with a spring 44 of any desired construction, as shown in Figs. 1 and 3 and in this manner the sliding end sections of the rollers are free to move outward, but are normally crowded inward, so that they will act at all times on the ridges over which they may pass and accommodate themselves to variations in the width of the ridges, and at the same time a uniform tension is exerted in an inward direction upon the said outer sections of the rollers, which tension may be increased or decreased at will, and this spring tension prevents the rollers from creeping up on the ridges.

A suitable seat 46 is located at the rear of the machine, supported by a spring-standard 45, attached usually to the central beam 13 of the frame.
