We, THEoPnILUs F. BERTRAND and PETER' SABES, both of Rockford, in the county of Winnebago, in the State of Illinois, have invented certain Improvements in Cnltivators, of which the following is a specification..

The object of this invention is to simplify and at the same time make the cultivator susceptible of 'easy adjustment to dilierent crops and the varying modes of cultivation as practiced by different persons upon diterent soils and the different sizes of plants that are being cultivated; and

Our invention consistsI in the special construction, arrangement, and combination of the parts that compose the machine, so that a greater number of changes and adjustments may be made with a fewer number of parts, and fullyr accomplish the object sought, than by any other machine within our knowledge.

In th e" drawngl Flgure'l represents'a side elevation of our cultivator;

Figure 2, a plan view of the same;

Figure `3, a plan view of the auxiliary frame and.

what is attached thereto.;

Figure 4, a section through lthe eye-bolt and socketplate and bed-plate; A Figurel 5, a plan view of the hed-plate; and `Figure 6, a plan view of the socket-plate.

A and B represent the two wheels which receive and revolve on the arms of the bent axle C.

I) is the tongue of the cultivator, and is rigidly secured upon axle G by means of the raised bracket a; and is stayed in its place by brace-rods l and 2, these parts forming the main snpportingframe of the cultivator.

Tongue D extends hack of the axle C far enough .to receive and support ou its rear end the drivers seat b, and may consist of one or more pieces, and be tiexible or rigid, as desired. l

Forward of the axle O, and on either the upper or under side ,of the tongue D, is firmly attached' the cross-piece E, the ends of which furnish fulcrumsupports for levers F and F and abutments for rods 3 and 4.

Upon axle C, and equidistant from fthe center.v

thereof, are secured the vertical, or nearly vertical, standards c and e', near the top ends of which are friction-pulleys :c x'.

d and d' are curved lnotched bars, fastened to the rear 4side of axle C, and near to thenstandards c and c. These notched hars extend upward from the axlel and pass through levers F and'F', and their curvature agrees with the segment of a circle, formed by the radius, having the same length as that on the levers from the point at which they are pivoted to crosspiece E and the point where they pass upward through 4said levers, and they are stayed at their upper ends to standards 1c and c by bolts 5 and 6, ang forward to the cross-piece E by stayrods 3 anA 4.

F and F are two' levers, plvoted at their forward ends to vcross-piece E, and have a mortise made vertically through them to receive r'ack-bars d and d', so as to Vbe free to rise or fall, as may be desired, and be controlled in vsuch kvertical movement by springbolts, the ends of which are so arranged as that they are forced by the spring to engage in the notches of the rack-bars d and d' when theyuare held firmly in their place, and will remain until the. bolt is withdrawn from the notches in the curved rack-bars by means of the pivoted hand-lever e, connected to a draw-rod, and so constructed as to operate the springbolt that engages in the notches in the curved rackbars 'a'nd when the levers arcfree to rise oir-fail.

f and f' are caps on levers F and F' for cpvering and protecting the springs on the spring-bolts from becoming filled with dirt or dust, and thereby be inoperative.

H and H' are two beams, each carrying one or more plows, and are either pivoted vor rigidly secured to a yoke,v G, at their forward ends, and rigidlyA connectedtoward their rear ends by au arched connecting-bar K, secured thereto by means of screw stapleclamps h or other equivalent devices.

Thus the beams H and H can be, attheir rear ends, adj usted to any desired width by simply loosening the clamp-staples hand sliding said beams ou .arched connect-inghar K and tightening the clamp-l staples ]tagain. These parts constitute the auxiliary frame. Y

The forward ends of beams H and H' are separated by means of yoke G for thed purpose of admitting the more advanced crops or plants to enter and pass be'- tween them without injury.

For the purpose of preventing any rocking tendency in the auxiliary frame, bearings, projecting outside of beams H and H', are provided to receive the pendent ends of rods or chains 7 and 8. IIn this instance the projecting ends of archedconnecting-bar K furnish the bearings.

The auxiliary frame is connected with 'the tongue of the rigid frame by a staple, pivot-bolt, or other device, forward of the evener or whiie-treesr and extends rearward, and vibrates underneath the axle or rods or chains 7 and 8, which are secured to the pro-` jecting ends of arched connecting-bar K, from whence they are passedover pulleys x and ai, in standards c and e', andareveonnected to levers F and F' by eye-y bol't-s j, so that, when the levels F and F' are depressed, the plows will be raised out of the ground,

. vibrate laterally, and thereby enable the frame toV carry the plows clearof the plants that may be out of line; and in order to canse the auxiliary frame and plows to come under the control of the driver inthis respect, adjustable foot-rests M are made to be adjusted at the proper height on standards L, which have teeth or projections ou one side, and are rigidly secured to the auxiliary frame in such relation to the drivers seat as would be most convenient in operating the frame and plows to preserve the proper distance from the plants..

The foot-rest has an opening in it of the proper shape to pass `over the toothed-bar L, and when in its place, and at the proper height, it is held by the force of gravity alone; but in consequence ofthe rapid movement of the cultivator over rough places the footrest M is subjected to such kind of sudden jars as will cause it to, become loose and may be thrown out of its position, and to avoid such casualties'we provide a wedge, 9, that, when placed in the opening in the foot-rest oppo'site'the teeth on the standard, will eectnally prevent their existence.

P is a screw eye-bolt, having a shank, p,-that passes through a tinted circular socket-plate, Q, and

bed-plate R.

Q is a circular socket-plate or block, iluted to receive the shovel-standard O, and thronghwhich the shank p of eye-bolt P passes. s

R is a bed-plate with recessed bearing, to receive the plate or block Q, and is secured, by screw-bolt or other-means, to the beams H H in proper places to receive the eye-bolts P.

Eye-bolts P receive the standards or stocks O of the plows bypassing lthe upper end of the standards through the eye of the eye-bolts P.

O 0 are the. plow-standards or stocks, and have the Aplows securely attached to their lower ends.

lis a ring that encheles each of the standards or stocks 0 above the shovels, the fronts of which are fitted to-receive thev rear ends of the brace-rods lc, to

which they are connected by a safety-pin, i, and the fbrward ends of brace-rods Ic are fast to beams H and H', as seen in figa-1 and'2`. i

i t' are safety-pins, made of wood, and strong enough to hold the plow in ordinary work without breaking; but when a plow strikes a rigid obstacle, the pin i will break, and leave'that plow with the standard or stock free to turn back unhurt, when it can be turned back again and a newwooden pin in. serted, and the cnltivator is readyfor work again.

By. this constrnction and arrangement of parts the standards o1' stock 0, with the plow attached,can be Vturned to any angle desired in either direction, and

so that the plow will throw' the loose ground that they raise either to or from the plants. in the rows which are being cultivated; the plow can be adjusted to any desired depth in the ground, or be raised up and held above and out of contact with the ground; will permit a plow or any of the plows to encounter arigid obstruction without injury to the cultivator, only requiring the insertion of a new wooden pin and at the same time allows of an easy but limited side 'movemept of the auxiliary frame and plows by the force exerted by the driver through his feet upon thev foot-rests or supports to so control their direction as to safely cultivate such plants as have been irregularly planted or that may not have come np in straight lines, and makes our cultivator effectively perform a! coming in contact with such plants as may be out of a straight line in the rows.
