Letters Patent No. 113,169, dated March 28, 1871.

IMPROVEMENT IN LANEROLLERS.

The Schedule referred` to in these Letters Patent and making part ofV the same.

Jersey, have invented a new and useful Improvement in Land-Rollers; and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled. in the art to make and use the same, reference being had to the accompanying drawing forming part of thisv speciica'tion, in whic Figure lis a top View of our improved land-roller. Figure 2 is a detail sectional v'iew of the same taken through the line a: x, fig. 1.

Figure 3 is ,a detail sectional view of thesame taken through the line y y, iig. 1. A, Similar letters of reference indicate corresponding parts. j

Our invention relates to improvements in that particular class of land-rollers in which three cylindrical sections or rollers are arranged to oscillate, each on its own axis, in a frame, in someA Way connected I The invention consists in the construction ot" the main framework,.whereby.to avoid the use of end cross-bars and pivot the 4frame ci' the rear roller in the rigid rear' extension of the same, the pole or tongue 1oeing pivoted, as hereinafter described. r

A B O are the' cross-.bars of thepframe, the two front ones of which are connected with each otherby two bars D, which are placed at equal distances from the center of the said oross-bars A B, and at a distance apart less than the length of one of the parte,

of the roller. l

Tho bars A B are made of suoli a length that their ends may project a little beyond the centers of the end parts of the roller.

The two rear cross-bars B O are connected by two bars E, which are placed at a distance aparta little more than the length of one of the parts ci' the .rollen The rear cross-bar C is made of suoli a length that its ends will not project beyond the bars E, as shown in iig. l.

F is the tongue, which is jointed to the middle part of the front cross-bar A by the bolt G, which passes through the hounds of the said tongue and through lugs or supports attached tothe said bar A.

The jointed tongue relieves the horses necks 'om pressure whileworking the roller.

H is the roller, which is made in three parts.

The two end parts are placed in front, in line with each other, and at such adistance apart that the ground left unrolled between them will be all rolled by the middle or rear part of said roller as, showni'nl gEach part of the roller H is 4formed of heavy wooden staves, h1, clamped between cast-iron heads h2 by long lbolts h3.

The headsh2 consist of an iron rim connected with the journals by arms, which are strengthened by ribs upon their sides, the whole being cast solid in one piece.

The rims of the heads h? are grooved upon their inner sides to receive the tenons of the ,staves h1.

The inner flange of said grooves is made widerthan the outer ange, as shown in iig. 3, so that the tenons of the -staves k1 may rest upon said inner flanges when putting the roller together, and may be forced into the grooves by drawing or forcing the two heads h2 towardeaoh other.

,h3 are long bolts passing longitudinally through the end parts ofthe arms of the heads l1?, where they are widened to join the rims of said heads, the ribs of the arms at that point being out away or recessed to receive the heads and nuts ofthe bolts, so that said heads and nuts may not project beyond the said heads h.

Y I are rectangular frames placed around each oi' the parts of the roller H, and to the middle part'smf the end bars of which the journals of the heads hZ are pivoted.

The front and rear cars of theframes of the two vend parts of4 the roller are pivoted at their 'middle points .to the ends of the cross-bars A B of the main frame.l l The front and rear bars of the frame I of thea-ear or middle part of the roller are pivoted to the centers of the two rear cross-bars Bv C of the main frame of the roller, as shown in iig. l.

By this construction, in rolling on new or rough ground, while one of the rollers H may be passing over a'stoneor stump, the other end of the frame.

cannot come lin contactwith a-sirnilar obstruction, since it does not pass beyond the pivots of the frame l; in other words, does not embrace the end of" the opposite roller H. The sam eprincipleqapplies when the machine is used to roll the sides and bottom of a ditch, since the ends of the lid-shaped frame A B D' cannot reach the sides of tbeditoh.

By connecting the three rollers in one rigid frame. weare enabled to guide the same veryaccnratelyr' and, the tongue being hinged, the weight of frame isv placed entirely on the rollers and none of it upon the team.

Byy pivoting the rear roller in a rigid extension of' the H-frame the weight or pressure on the same is increased.

We claim no single element or device in our ma`- herein shown and described to form an improved landehine; but roller.

Having Jnhus described our invention, JOHN T. HUDNET.

P We claim as new and desire to secure by Letters HOLLOWAY W. MATHEWS.
