SPECIFICATION forming part of Letters Patent No. 543,379, dated July 23, 1895.

Application filed November 27, 1894:- Serial N0.J530,148. (N od l.)

To all whom it rota/y concern.-

Be it known that I, JAMES EDWARDS, of Peru, in the county of La Salle, and in the State of Illinois, have invented certain new and useful Improvements in Cultivators; and I do hereby declare that the following is a full,

clear, and exact description thereof, reference being bad to the accompanying drawings, in which- Figure 1 is a perspective view of a cultivator constructed in accordance with my invention; Fig. 2, a plan view thereof; Fig. 3, a longitudinal section of the same; Fig. 4, a detail perspective view of the adjustable coupling, and Fig. 5 a vertical section through the same.

' drawings, is, as usual, provided with two carrying-wheels A and Athat are journaled upon the opposite ends of an arched axle B. At the transverse center of the latter I pivotally connect an open frame 0 that consists of a curved or loop-like bar or bars between whose front ends the rear end of the tongue or pole D is placed and to which it is fastened. The tongue may, if desired, be directly pivoted to the axle, but I prefer to use the construction described. 7

Upon each side of the tongue-frame O, in the same horizontal plane, there is a barE that is rigidly attached at its rear end to the axle B and thence extends forward, converging slightly toward the other bar E, and connecting the front ends of said bars E and E are two parallel rods or bars F and F, one of which is above and the other below the tongueorpole D. The lower bar F projects horizontally outward beyond the point of its connection with each bar E and has a downward extension f, which latter, with a like extension 9 from a shorter bar G that vis secured to the under side of said bar F, provides means for the attachment, in the manner to appear, of

the beams or bars H and H of plows or shovels I and I at each side of the machine.

Pivoted to suitable brackets that are attached to the axle B are two levers K and K, each of which is located in the space between the tongue-frame G and a bar E, and at its upper end is connected by a link J0 with the side of said tongue-frame. The lower end of each of said levers is extended horizontally to receive the foot of the operator, and is sit uated so as to be in ready reach from the seat L.

lrVith the cultivator constructed as thus far described, should it be desirable to changeits direction when in use,'so as, for instance, to carry the shovels to a corn-hill outof line, a

slight forward pressure by the foot upon the free for driving or manipulating other parts of the cultivator, and, besides their functions as levers, said levers K and K form rests for the feet.

, Each gang of shovels is attached to the appropriate depending portionsf and g of bars F and G, respectively, so as to enable the shovels to be adjusted in or out with reference to the row of corn. for this purpose will now be described.

Journaled upon a long bolt M, that extends horizontally between each pair of the extensions f and g is a tube or sleeve N, that has a number of radial lugs n and 0% arranged in a straightline, and upon each sleeve is journaled the front ends of the cultivator-beams H and H. Each of said ends has a radialslot h of such size as to pass over the lugs n and when the latter align with it, and within said end is a cavity it that communicates with such slot .h, into which a lug n can pass when the tube N is rotated, and thus hold or look the beams H and H against sidewise movement.

Themeans I employ ICO Normally, the sleeve is kept in such position by a weighted handle or arm m that the lugs n and n and slots 72. and h are out of alignment, so as to prevent sidewise movement of the bars H and H, but when it is desired to change the position of the bars horizontally the sleeve N is revolved to place said sleeves and notches in alignment, and then the beams II and H are slid along to the desired position and there locked by turning or permitting the turning of the sleeve to destroy the alignment of lugs and notches. Lateral adjustment of the shovels is thus extremely easy and simple, there being no nuts or bolts to be removed and replaced.

For varying the depth to which the shovels work, and to enable them to work when going up or down hill, the tongue D is pivotally connected upon a horizontal bolt between the front ends of the frame C, in rear of the bars F and F, and to the rear end of said tongue is connected a hand-lever O that is within convenient reach from the drivers seat and is pivoted to a segment I which is attached to the frame 0, said segment being toothed for cooperation in the customary way with a locking-pawl carried by the lever for holding said lever in the position to which it may be placed. To prevent obscuring of other parts the lever and segment are omitted from Fig. 1.

By means of the lever O, in view of the pivotal connection between the tongue and frame, said tongue and frame may be placed in such relative positions as to cause the shovels to go deeper or shallower into the earth and be made to work the earth when going up and down hill.

For raising and lowering the shovels, by rocking the beams on their pivotal connection with the sleeves N, each gang is connected to a hand-lever Q that is pivoted upon the axle B in convenient reach from the drivers seat L.

The seat L is mounted upon the rear ends of two forwardly-extending bars R and R that, near their front ends, rest upon the axle B, and each of saidends is carried downwardly at p and connected by a bolt to the adjacent bar E. Each end 29 has a vertical series of holes to enable the height of the seat to be adjusted, either for the purpose of lifting the operator entirely above the corn, or to lower him so that his feet may reach the ground to enable him to kick clods of dirt from the'corn as he rides along. 1

While preferring the precise construction and arrangement of parts shown, I wish it understood that I do not limit myself thereto, as changes can be made which will involve no departure from the scope of my invention.

Having thus described inyinvention, what I claim is lever to move said tongue, or pole Vertically, substantially as and for the purpose specified.

2. As an improvement in cultivators, the combination of the axle, the tongue or pole pivotally connected therewith, and a downwardly extending foot lever, having a horizontal pivot, at each side of, and connected to said tongue or pole, substantially as and for the purpose shown.

3. As an improvement in cultivators, the combination of ashovel supporting frame, a tongue or pole pivotally connected therewith, and a downwardly extending foot lever ateach side of, and connected with the tongue or pole, and having a horizontal pivot, substantially as and for the purpose set forth.

t. As an improvement in cultivators, the

combination of the axle, the tongue or pole pivoted thereto at its rear end, the horizontally pivoted, downwardly extending foot lever, at each side of said tongue or pole, and a link connecting the upper end of each lever with the pole, substantially as and for the purpose described.

5. As an improvement in cultivators, the combination of an axle, the pole or tongue pivotally connected therewith, levers connected with opposite sides of said tongue, the two forwardly extending bars attached to the axle upon opposite sides of the tongue, bars above and below the tongue which connect the front ends of said forwardly extending bars, and suitably connected gangs of plows, substantially as and for the purpose specified.

6. The combination of a support, a plow beam, having an opening or eye, and the rotary part passing through said eye and connected to the support, that has alug adapted to be placed in and out of alignment with a slot in the beam, substantially as and for the purpose shown.

7. The combination of a support, a plow beam having an opening or eye, a rotary part passing through said eye and connected to the support, that has a lug adapted to be placed into and out of alignment with a slot in the beam, and means to normally keep said lug and slot out of alignment, substantially as and for the purpose set forth.

. 8. The combination of a suitable support, as bars, a bolt extending between said bars, a sleeve jonrnaled on said bolt and having radial lugs, a plow beam mounted on the sleeve and having a radial slot for the'passage of the lugs when the same aligns therewith, and a handle attached to said sleeve for rocking the same to place lugs and slot into and out of alignment,substantially as and for the purpose described.

In testimony that I claim the foregoing I have hereunto set my hand this 2d day of November, 1894.

JAMES EDWARDS.
