Letters Patent No. 90,905, dated June I, 1869.

The Schedule referred to in these Letters Patent and making part of the Bama To all 'whom this may concern.:

v from the ame of the cultivator.

` Figure 3, a plan view of the rodwhich is used to raise and lower the shovels.

Figure 4, an elevation of one of the axle-tree arms, with the wheel removed.

The present invention relates to an improvement in that class of cultivators that run on wheels, and carry a frame that supports the working-devices; and

Its nature consists in the novel means used to raise and lower the shovels, and give them aneasy lateral motion, and Ain supporting the forward ends of the beams with loop-bolts, so arranged as to give a sidedraught, to counteract the pressure of the earth against the mould-board shovels, when they are carried toward the row to form hills and, further, in the novel means provided for so changing the position of the beamsV from the front of the frame to a rear attachment, as to provide a walking-cultivator, and so arranging the frame as to be adjustable on the axle-tree arms, for the purpose of balancing it, when the shovel-beams are changed, either into a walking or ridingoultivator.

To enable others skilled in the art to make and use my invention, I have marked like parts, in the several figures, with like letters, and will now give a detailed description.

A A, ig.1, represent a substantial frame, which is fastened together by cross-pieces E E, D D, and it is bolted fast to the axle-tree arms F F, at S S, two or more holes, T, being made through the frame, in front of said arms, for the purpose of adjusting it far enough back to balance, when the operator is to walk in the rear ofthe cultivator, and guide the shovels.

The peculiar form of the arms is shown at g. 3, F'

v being the chair on which-the frame A bears, and a the back of the chair, which bears againstvthe inside of the frame, and prevents it from getting out of place.

To move the frame A back, all that is required is to remove the bolts S S from it, and put them through the holes T in front.

I do notV claim to have originated the principle` of balancing frames on axles, to conform to walking and riding-cultivators, but limit myself to the construction herein shown to accomplish this purpose.

The cross-pieces D E are fastened to the upper and lower side of the 'ame A, by means of bolts K K, and they have a series of holes, I J, made through them, to receive'loop-bolts C O, which are putin either two of the holes, J, (according to the width of the row to be cultivated,) when the operator is to ride, and in thev holes I, when he is to walk in the rear, and guide the shovels L, by means of handles ff.

Each of the loop-bolts C has a long' shank, that is rounded at the upper end, and turns in the holes I, when the shovels L have alateral motion, and a pin ,put through its upper end, to hold it in place, a

washer, e, being put under the pin, to prevent it from g wearing. v

rIhe opposite ends of the bolts are so turned up as to provide suitable loops to support the forward ends of the beams B B, a series of holes, x x, Sto., being made through the loops, to receive the bolts which hold said beams in place.

It will be seen by this description, that the pivots U, ou which the beams turn, are placed at the inner sides f the line of draught.

This is done that the shovels L may be easily thrown inward to hill a row, and held in that position with little or no force. v

The device for supporting and raising the shovels consists of an iron rod, G, figs. 2 and 4, which is `so bent at the ends as to form short elbows mm and pivots W, and also a shank for securing the lever V, the elbows m operating as levers for raising the beams B B, and the pivots W tting into sockets, or boxes, secured to the rear end of the frame A A.

The straight part ofthe rod supports sheave-block and pulleys H, the blocks supporting the chains, which are fastened to the beams B B, and used to raise and 'lower the shovels L, and the pulleys to roll on the rod,

and thus permit the shovels to have au easy lateral motion, whether they run a greater or less depth in the ground.

A curved standard, N, fig. l, ls secured to the rear end of the tongue A, at U, and supports a latch, R,

which is pivoted to a short strap, P, fastened to said standard, and has notches in its under edge, which v lock over the rod G, and hold it in position, the lever Y being used by the operator to put the rod in place.

The operation is so simple as to require no particular explanation, the whiletrees being attached to the draught-rods g g, and the operator sitting on the seat r, when the beams B B are pivoted to the front of the cultivator, and walking in the rear, when they are pivoted to the cross pieces D D.

Having thus described my invention,

What I claim, and desire to secure by Letters Patent, is l l. The rod G, in combination with the lever V,

sheave-blocks and pulleys H, beams B B, shovels L, 3. The combination of the frame A A, cross-pieces standard N, and catch R, the whole being constructed D E, loop-bolts C, beams B B, shovels L, and axleand arranged substantially as and for the purpose set tree arms F, said arms being adjustable on the frame, forth. and constructed as and for the purpose described.

2. The combination of the loop-bolts C, beams B B, L. H. WILKINSON. shovels L, and cross-pieces D E, the latter having a Witnesses: series of holes through them, for adjusting the beams, R. W. TOVELL, substantially as herein described. M. RICE.
