LAND-ROLLER.

' Specification of Letters Patent. Pate ted June 18, 1918.

' Application filed-August 5, 1916. Serial No. 113,403.

To all whom it may concern Be it known thatLGEoRon WRIGHT, a citizen of Canada, residing at Chatham, the county: of Kent and Province of- Ontario,

Canada-,- have invented new and usefulIrnprovements in Land-Rollers, of which the following is a specification.

My inventionrelates to improvements in land rollers the objects thereof being to providea-roller'that will roll uneven ground with equal pressure whether it be a knoll or hollow.

The frame of my roller can be made lighter than ordinarily, as the dralft is directly from the rear in the middle between the two rollers; also, in my invention the rollers are l closer together endwise, and therefore, leave a smaller ridge between the rollers.

I attain these objects in manner as illustrated in the accompanying drawings, in Which':-'

Figure 1 is aperspective' view of the coml Fi 3 i a crosssection'of a single roller plete rollers; g

Fig. 2 is a front'view, the dotted lines showing how each section acts on uneven ground through 1-2 of- Fig. '1 i t Fig. 4' is an endview; of roller'with'part cut away showing the connection of the draw rodfrom tongue to rear; Fig. 5 is atop View of outer end of showing how j ournal is hung in frame;

3 Fig. 6 is an end view of shaft, journal and pif 1 shaft Fig. 7 is a side View of bracket hanger at outer end of rollers, showing how the journal move'sba'ck and 'fortli'as the inner end of rollersmoveup ordown when passing over uneven ground;

Fig. 8 is a side view of inner end of shaft with square box journal thereon, and

Fig. 9 is a top view thereof.

Similar letters refer to similar parts throughout the several views:

Referring to Figs. 1 and 2, the rollers are shown in two sections, inclosed by a frame B which is made from heavy steel bars. To this frame are fastened standards B. B near each end, and E in the middle projecting below the frame in front and rear, and having holes bored through said pro ections. On these standards is placed the platform 0. supporting the seat D and also on which to place additional weight if required. The

tongue is attached to the front at the standard E and braced to the frame B. Through the lower projections of the standard E a draw bolt or rod F. is placed, bolted to the tongue and extending to the rear of frame B, where it is secured by jam nuts which hold the frame rigid; outside of the jam nut is a knuckle to which a small roller can be attached as shown inFig. 4. This roller is to level down the small ridge left between the large rollers. On each corner of frame B. are fastened brackets Q on which is hung a shaft K, having a right and left hand coiled spring firmly fastened at each end to a lever J, and in the middle to a ratchet wheel L. which is kept taut by the tension rod M. fastened to the ends of frame B. The outer ends of therollers A'arehung directly from frame B. but the inner ends are hung to an inner frame H.'which swings in frame B. on lugpins G., Figs. 2 and 3. i

It i by means of these pins that the rollers are allowed to raise and lower as they go over uneven ground. It will readily be seen j that whena roller strikes a knoll or high spot'it will rise and go over it, but when a hollow spot intervenes pressure will require 1 to be applied to make it touch the low spots,

and give an even bearing. This may be done in various ways, by placing wei ht on the inner end, by automatic pressure or by a flat or coiled spring, of these plans I have adopted the coiled spring. To make the pressure effective I connect levers J and the ends of inner frame H. at R. with rods I show in Figs. 1 and 2.

To enable the rollers to work freely over uneven ground the inner end of roller shaft N. Fig. 3, has a square boxing I) having a center hole 7' in which the pivots of the brackets a are inserted as shown in Figs. 8

and 9, said brackets being bolted to the inner frame H., part of boxing b is out way in Fig. 9 to show the pivots in the boxing. The outer end of shaft N. revolves in a journal 0, having pivots e, on each side, which hang in the slotted brackets P. attached to frame B. more fully shown in Figs. 5 and 6. The dotted lines in Fig. 7, show how the journal 0 moves back and forth as the inner end of roller moves up or down. The boxing 6 and journal 0. are kept in place with a key a at each end of the shaft N.

To operate the rollers, the coiled springs are set to the required tension and held in place by a rod m catching 'oper the ratchet:

VVhat I-claim'as my invention: and, Wish.

to secure by Letters Patent in sectional land rollers is 1. The combinatlons of right and left handcoiled springs encircling a shaft mounted on brackets secured to. the outer ends? of; a main frame,. one end of said springs beingattached to a ratchet Wheel set in the middle oftsaid vshaft-with means to hold said springs in tension, their opposite ends being secured to levers projectmg' fromthe ends of said shaft; an inner frame comprising end piece and arms projecting at right angles therefrom parallel with sidesof main frame vith means to hangsaid in:

nerqframe. from the said.1nain frame, and' connecting rods with mean to connect the above mentioned levers by. the said connect: 'ingrods .to-f the ends of aforesaid inner frame.

- 2. The combination with a..roller and. frame of asquare journalboxing at inner endof' roller having a. circular holelongilongitudinally through itscenter ofdiameter sufficient to admit the roller shaft, and hav tudinally throughits center ofsufficient size to admit theshaftof the roller with means to secure saidboxing to inner ends of said shaft, and brackets secured to the frame, the

site sides With means tosecurei sald Journal outer ends of said brackets terminating. in circular pivots that fit into perforations made onopposite sides of the square part of above mentioned journal boxing.

3. The combination With a roller of a round journal boxing at the outer end of roller having'a hole bored longitudinally through its-center ofsufficient size to admit intone? an end piece at innerjend of roller,- andarms-n projecting outward parallel. withv sides of main :frame, andhaving. lugs, to hang said inner frame. fromzthe main frame, right andleft hand coiled springs encircling a shaft mounted "onbrackets secured to theouter ends of the mainframe, the inneren'dsof said springsbeing/attached. to. a ratchet wheel setiin themiddle of said shaft with means to hold said springs in-tension, their.
