WILLIAM P. BROWN, OF ZANESVILLE, OHIO.

Specification forming part of Letters Patent No. 220,463, dated October 14, 1879; application filed Aprn 12, 1879.

To all whom it may concern;

Be it known that I, WILLIAM'P. BROWN, ot' Zanesville, in the county ot' Muskingum and State of Ohio, have invented cert-ain new and useful Improvements inliding andWalking Cultivators; andI- do hereby decla-re that the followingis afull, clear, and exact description of the invention, which will enable others skilled in the art to which it apperta'ins. to make and use the same,reference being had to the accompanying drawings, and to letters of ref-` erence marked thereon, which form a part of this specification.-

Figure l of the vdrawings is a perspective View of my cultivator, and Fig. 2. is a perspective detail view of the same.

Identical parts in the drawings are designated by the same letters.

My invention relates to combined riding and walking cultivators 5 and it consists in devices for raising and lowering the front andA rear ends of the cultivator-beams simultaneously and by one movement.

It also consists in the manner of adj ustably attaching` the cultivator-beams to the carriageframe, and also in the manner ot attaching and adjusting the guiding-handles when usedl as a walkingcultivator.

A is the carriage, and A is the spindle ot' the axle, and B is the carriage sub-tongue. The axle is arched upward and attached to the sub-tongue at B. C is a draft frame or bracket, attached to the sub-tongue at Bz'in advance of the axle A, and extending downward about level with the spindle A. Cl is a brace extending from the axle near the spindle to the bottom portion of the frame C, and provided with a serie's of holes, b, for the purpose of supporting the bracket or frame C at diierent angles or positions.

There is a slot, G2, in the vertical parts of the bracket (l, in which the draft-bolt D is inserted, provided with the sleeve D1. 4

E is the frame of the cultivator, to the forward end of which is attached the clevis El, which embraces the sleeves D1, and is retained in position by means of the set-screw D2. The

'beams E are united by the bolt c and the spreader c1. E2 is the guiding-handle, which is attached by clasp c2 to the extended end of the bolt e.

G is afulcrum or rest for this handle, provided with a slot, g, to which the handle is attached by means ot' the bolt g in any desired position on the curved rest G, thus providii'ig` a shifting or adjustable handle. Instead of this slotted and curved brace G, there may be a curved bar or rod, and an engaging `staple or hook in the handle to attach the parts,

instead of the slot and bolt, as described.

H and H are toggle-levers, connected with the bracketat It L, and with the draft-bolt D at each end of the sleeve D1, and to each other by the bolt h2, and so constructed that in case these toggle-levers are deflected from the vertical position they will cause the draft-bolt D to be raised.

F is a lever fulcrumed to the sub-tongue at f, provided with the hand sprin g-pawlf ,which engages with the segment-ratchet F1 in any desired position. K is a link attached to the arm F2 of the lever F by means of' hook and eye 7c. The lower end of this lever has a lug, k1, with a hole, k2, in it. K is a hook-bolt for securing the stem ot' the lever K and permitting it to pass freely through it; or the hook 7c3 of the hook-bolt may be inserted into the hole k2, thus making a rigid attachment of these parts.

L is a rod connecting the lever K and the toggle-levers H, so constructed that as the lever F is operated, the toggles and lever K move in such a manner as to raise and lower the front and rear ends of the plow simultaneously and by the one movement.

ln case it is to be used as a walkingcultiva tor, the hook k3 ot' the staple-bolt kl should not be engaged in the hole k2 of the lever K, by this means permitting the cultivators to be raised and lowered by the handle El. In case the hook 7c3 is engaged in the hole k2, the weight ot' the carriage and plowman may be utilized in forcing the plow into the ground.

M is a stirrup engaging the draft-bolt D between the sleeve DI and the bracket G. M is a rack on the stern of the stirrup. N is a lever, provided with a segment-rack, Nl, upon which are teeth for engaging with the rack M. The longer and fore arm ot' this lever is provided with a series of holes, in either of' which may be placed the bolt of the connecting-rod N2, which connects the lever N with the lever F. The lever N is fulerumed tothe sub-tongue by the bolt n. By means of this lever and its connections, constructed as described, the draft-bolt I) is raised and lowered by the direct vertical motion given to the stirrup M.

The hook and eye I: and the clevis-bolt c3 provide for a horizontal swinging motion for the cultivator, enabling the operator to guide the same so as to avoid the corn.

The cultivator, as constructed for use, consists of a duplication of the parts above described and represented in the drawings, with the operators seat situated midway between the handles E2 and lever F.

In case one of the wheels of the carriage drops into a furrow, or upon higher or lower ground, the operator can at once raise or lower the cultivator to suit, either flexibly or rigidly, as hereinbefore described.

What I claim, and desire to secure by Letters Patent, is-

1. In a riding and walking cultivator, the lever F, provided with the spring-paw] f and arm F2, in combination with the segmentratchet Fl, the lever K, connecting-rod L, toggles II H', and draft-bolt D, as and for the purposes set forth.

2. The lever K, provided with the lug k1 and hole k2, engaged with thelever F2 by the hookand-eye joint lf, in combination with the hookbolt K', eultivator-beam E, and the connectingrod L, substantially' as and for the purposes set forth.

3. In a riding and walking eultivator, the bracket C, attached to the tongue B and to the axle A by the brace C', and provided with slots U2, in combination with the draftfbolt D, the sleeve D, and the adjustable elevis El, provided with the set-screw D2, substantially as and for the purposes set forth.

4. In a riding and walking eultivator, the combination of the lever F, the connectingrod N2, the lever N, provided with the segment-gear N, the stirrup M, provided with the rack M', and the draft-bar D, constructed and operating substantially as and for the purposes set forth.

5. Ina riding and walking cultivator, the combination of the lever F, provided with the spring-pawl f' and the arm F2, with the segment-rack Fl, lever K, connecting-rod L, toggles H II', and draft-rod D, and the connecting-rod N2, lever N, provided with the segment-gear N, rack M', and. stirrup M, substantially as and for the purposes set forth.

In testimony that I claim the foregoing as my own I aix my signature in presence of two witnesses.

WILLIAM I. BROWN.
