IMPRovEMENT 'rrr LAufn-Ronnrms.

Lhe'Shedule referred to`i these Letters Patent and part of the same To whom 'it may concern: l l Be it knownthat we, lijn-Iseli` WBITCOMB and DANIEL A. GUNN, of Waterville, in the county of Lucas and 4State of Ohio', have invented a new and usefulv Improvement in Land-rollers; .and we do declare that thefollowingis a true and accurate description thereof,jreference being had to the accompanying drawing and to the letters of reference marked theres onand being a part of thisspeciicaton, in which-J- Iligure l is a perspective of our, improved roller, an(

Similar letters of reference indicate corresponding parts in each'/gure. A

'lhe nature of this invention relates to an improved construction of land-rollers, andconsists in the arrangement of a third roller'behiud two principal rollers, said roller being jonrnaled in a 'fi'arne hinged 4to the back part of the main frame, and in a peculiar device wherebythe driver canv at will raise Vthe. third roller from -tue ground; also, in the-employment of a cylindrical 'zpunter-weight, traveling between and on vsuitable guides and ways o n themain frame, to serve as a counterpoise to the third roller whenthe latteris raised-omthe ground, and,\yhen lowered, the weight isrun hack near therollers, where its weight adds to their efiiciency; also, in the mechanism for operating said counter-weight, as Vmore fully hereinafter s'ct forth. l

' A represents the main frame of ouri-mprovement,. provided with draft-'pole B'. i f 0 are timbers" longitudinally secured to the main v frame A, of `which they-make part.

D are rollers, whose axles are jourualed in the parts l(l 'and the end-pieces of the frame.

E is a cylindricall counter-weight rolling on ways at thebottom of and between the guide-timbers C.

Fis a standard erected across the'rear ends of the guides O. f

'c is a sheave journalcdin a mortise in' said stan-` dard. Y

G is a shaftpjournaled in the front c nds of the guides O, .and- A i G is a grooved pulley-secured to and rotating with said shaft-; said pulley isprovided or studded at inter vals on itssides with projecting spokes, by means of which the driver, sittingion the seat'H, may rotate s `thepulleygising his feet for that purpose.

v I is a cord or rope, starting from `the 4pulley G', is led back over the connter-weightiE, around which it is carried iu agroove formed'in itvfor that purpose,

making what is termed a parbuckle, thence back to `the 'sheave c, down under it and the counter-weight,

and around the pulley, where it is joined to the other end, Vforming an endless belt.

. J are bars p ivoted to therear beam of the main frame. l

K is a yoke suspendedV from the rear end of the lever L, which is pivoted in lthe standard F.

M is a third roller, whose axlesare journaled in the ends of the bars J andv pendent arms of the yoke K y .The front end ofthe lever L isy crotched, and terminates in a cross-bar, as shown; to this cross-bar are secured two cords or rupee-N, whose .other ends are secured to and coiled around the shaft G, at either side of its pulley..

In operation, all three' of the rollers act upon the surface of the ground, for the purpose for which such devices are employed, the'third roller going over the interval left by the others, vzmd,l being long enough to overlap their inner ends,-the formation of a ridge is prevented, which ridge is always formed where` but two rollers are employed.

Arriving at the end of the field, it is necessary, in order to turn, that the third roller should be elevated.; to do so, the driver rotates in aforward direction tlie pulley G pressing on itsspokes with his feet, when 's the ropes N are wound upon the shaftA G, drawing downthe long arm of thelever L, which in turn vraises the yokeV K iu which said rolleris pivoted, at the. saine time the counter-weight is parbuckled forward and acts as a conterpoisc for it, preventing undue strains on the horses necks; when the turn is made,

thethird roller is again lowered by the same means,

and the counter-weight moved back to the rear end of the guides, where its weight increases the efficiency of the main rollers, counterbalancing the drivers weight and lrelieving the horses necks. Suitable stopsarc provided in the guides to prevent the roller frombeing moved too far in either direction.

What we -claim-as our invention and desire to sccure by Letters Patent, isA

' l. "llliecounter-weght E, as and for the purpose set forth. i

2. 'lhe shaft4 G, pulley G', sheave w, and cords I and N, arranged with relation to each other and the counter-Weight E and lever L, as and for the purpose 'set forth.

3. The arrangement of vthe roller M, verticallyadjust-able," pivoted in the frame K J tothe rear center of the device, in connection with. the lever L, cords.
