IMPROVEMENT vIN LAND-ROLLER.

TO ALL WHOM IT MAY COIICEBI:l

Be it known that I, H. L. CURRER, of Oregon, in the county of Ogle, and State of Illinois, have invented a new and useful Improvement in Land-,Rollersg oil which the following is a full, clear, and exact description, reference being had 'to' the accompanying drawings, which make part of this specification, and in whieh- Figure 1 represents a planlor top view of my improved roller.

Figure 2 represents a view in elevation of one side of the same; and Figures 3, 4, and 5 are diagrams showing the roller in different positions. My invention relates to thatl class of rollers in which a series of rollers is united in a single machine for joint operation', and the improvement herein claimed consistsV in certain novel devices for increasing the cunabilites and effectiveness of the machine, as hereinafter more fully described. In the accompanying drawings, thc front roller A is shown as molnntedin bearings a, projecting underneath a rectangular frame, E, the rearcross-bar b of which projects laterally on each side of the frame n distance about equal lto the width of the frame-A tongue, .-.`D, projects centrally in front of the frame, to which it is secured by being inserted into loops or sockets d d on the frame, and held by a pin inserted into` it behind the loop. By this means the tongue is securely fastened, and yet can quickly he removed or replaced. A seat, E, for the driver rests upon a curved spring,-F, ou-e-end of whichisl fastened to the 'tongue in front of the loop, whicharrangement'allows both'the tongue'anlseat'to'bere'move' together. The seat has a'soeket, which slides i on theA spring, in order that the seat may be moved Vbackward cr forward to balance the weight of the tongue. The seat may be fastened to the spring by a pin .passing throughboth, or by aslot and set-screw. v A box to contain weights (to increase -the pressure ofthe roller) mayalso be placed on the frame. Two rollers, G II, are cach mounted in Aan independent frame, I J, in a manner similar to the front one. They are also furnished -with boxes K to contain weights, andwith. centrally-projecting tongues L, which are connected by clevises or loops M tothe projecting rear cross-har of the frontv frame, which mode of coupling leaves each frame free to play independentlyof` the others. The rear framesrnay-be adjusted nearer to or farther from cach other byA means of holes in the cross-bar, as shown in the drawings, or by slots and set-screws in the usual \ve llknown way. i

This independent and exihle arrangement of .my improved rollers afords many advantages in practical operation not possessed by others. v For instance, in mo'ving from field to iield,the rollers can be arranged one behind the other, as in iig. which is a great convenience in passing through gates. Again, in rolling walks or roads, they can be rolled three times by drawing the machine once over them, and with dilerent degrees of pressure, if desired, by varying the weights in the boxes.

In fig. 4 the front roller. is represented as running on level ground, while the rear ones are inclined towards each other as if running on the sides ota furrow. v'In tig. 5 the front and one hind roller are level, and one only is'tipped. v y l These illustrations might he multiplied, but the .instances given are suiiicient to showthe capabilities of my invention. In rolling down corn-stalks, previous to ploughing, my roller would travelY on three rows at once, and the ease with which it could turn round is obvious.

What I claimias my invention, and desire to secure by Letters Patent, is 1. The combination of the front roller with lthe independent and loosely-hinged ,hind rollers, arranged and operating as described. r

2. The combination, vwith th'e front roller, ofthe dri'rers seat anddctachable tongue, all arranged and operatingV as described.

3. 'The arrangement of the series of rollers one behind theother, as described, for the purpose of successively rolling the same surface by a single passage of the machine.

In testimony whereof I have hereunto subscribed my name.

H. L. CURRIER.
