SPECIFICATION forming part of Letters Patent No. 615,160, dated November 29, 1898.

A li ti fil d March 3, 1898. Serial No. 672,413. (No model.)

T 0 all whom, it may concern:

Be it known that I, LOUIA W. GRAUER- HOLZ, of Kensington, in the county of Smith and State of Kansas, have invented a new and useful Improvement in Cultivators, of which the following is a full, clear, and exact description.

The object of my invention is to provide a cultivator especially adapted for the cultivation of corn and which is so constructed that two rows of corn may be cultivated at one passage of the machine across the field. I

A further object of the invention is to provide for any desired number of plows carried by each cultivator-beam or the use of a single set of plows, if desired, and,furthermore, to provide for the adjustment of the plows relative to the ground and the speedy return of the plows to the soil in the event they meet with an obstruction, the return taking place almost instantly after the obstruction has been passed.

A further object of the invention is to provide a machine or implement of the character above described which will be exceedingly simple, durable, and economic in its construction.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of the improved machine. Fig. '2 is a longitudinal section taken through the axle adjacent to one of the supporting-wheels and at one side of the pole; and Fig. 3 is a transverse section through the plow-beams, the sleeve of the axle being likewise in section.

The axle 10 is an arched axle and carries at its spindle portions supporting-wheels 11. The axle at its bow or horizontal section is provided with a sleeve 12, which exteriorly is usually of polygonal shape. At or near each end of the sleeve 12 a collar 13 is mounted, the bore whereof is fitted to the exterior of the sleeve, and the said collars are provided with lugs 14 in transverse alinement, as shown in Fig. 3. The lugs of the collars are adapted to be above the sleeve 12, and when the lugs are in this position the collars are locked to the axle and the sleeve likewise,through the medium of set-screws 15, passed through the bottom of the said collars, through openings in the bottom of the sleeve 12, and to an engagement with the axle. The axle may be made in two parts, as indicated in Fig. 3.

Each collar is adapted to carry an upright, and each upright is ordinarily constructed of two side bars 16, connected at the top by a block 17, having a suitable eye formed therein at the back, and the lower ends of the side pieces 16 of each upright are pivoted upon a bolt or a pin 18, passed through the lugs 14 of a collar 13, as shown in Fig. 3. An arm 19 is fulcrumed between the members of each upright upon the pin 18, pivoting the said upright, and the said arms 19 extend forwardly, as shown in Fig. 2, and beneath each pivoted arm 19 an arm 21 is secured to the collar 13,over which the pivoted arm is placed, a rod 22, provided with a suitable head at each end, being passed through the forward ends of the upper and lower arms 19 and 21, while a spring 23 is coiled around each rod, bearing against the lower portion of the lower fixed arm 21 and against the lower head of the pin 22, as is also shown in Fig. 2.

Each upright is provided with fingers 20, which extend beneath and to an engagement with the pivoted arms 19, so that when the uprights are carried rearward the spring 23 will be placed under tension, and when tension is removed from the upper ends of the said uprights 'the springs 23 will restore the said uprights to their normal position. The tongue or' pole 24 is secured upon the central portion of the sleeve 12 of the axle. A whiffletree is pivoted on the said pole, being designated by the numeral 25, and the whiffletree is provided with an equalizer consisting of a lever-arm 26, pivoted to the tongue or pole at the rear of the whiffletree, and links 27, which extend from the lever-arm to a connection with the said whiffletree, as shown best in Fig. 1.

Bars 28, which are a part of the frame of the device, are attached to the poleor tongue at each side in front of the whiffletree, being curved outwardly at their forward ends and carried rearwardly to a point over the axle and through clips 29, which are secured to the axle. Seat-supporting bars 30 are adj ustably attached to the frame-bars 28. These seat supporting bars are carried rearwardly beyond the axle and are connected by a crossbar 31, upon which the drivers seat 32 is placed. The seat-bars 30 are also supported in st-irrups 30 at the rear ends of the seatbars 28. Braces 33 are attached to the spindle portions of the axle and are carried upward to the side bars 28 of the frame in order to impart the necessary rigidity to the said frame. A cross-bar 34 is pivoted upon the under face of the tongue or pole 24 at a point in front of the whiiiietree 25. The said crossbar extends beyond the side bars 28 of the frame and is usually attached to the said side bars, and the cross-bar 34 is provided at its ends with a number of apertures or openings Forwardly and downwardly inclined attaching-bars 36 are adj ustably carried by the cross-bar 34 by passing suitable bolts through the attaching-bars and through desired openingsin the cross-bar 34, as shown in both Figs. 1 and 2. Two plow-beams A and B are car ried by the frame of the machine. Each plow-beam consists of a forward upwardlycurved section 37,which is adjustably secured to one of the attaehing-bars 36. At the lower end of the forwardly-curved section 37 of the plow-beam two

zigzag bars

38 and 39 are pivotally attached, the inner bar being of greater length and extending farther rearwardly than the outer bar, and the rear ends of the two

bars

38 and 39 are straight, and the space between the two members or

bars

38 and 39 is about equal throughout its length, except where said

members

38 and 39 are brought together and are connected with the upwardlycurved forward member 37 through the medium of a suitable pivot-bolt 40. Plowshares 41, of any suitable description, are carried by the

members

38 and 39 of the plow-beam, and the plowshares are preferably so placed that the shares upon one member will alternate with the shares upon the other member.

About centrally between the ends of the members of a plow-beam a pivot-bolt 42 is located, as shown in Fig. 3, and upon the inner end of the pivot'bolt a stirrup 43 is placed, adapted to receive the drivers foot. A tube 44 is pivoted on the pin or bolt 42, and the said tube is provided with a series of apertures 45, adapted to receive a locking-pin 46, and at the forward upper portion of the tube 44 an eye or a hook 47 is formed, to which the upper end of a spring 48 is attached, the lower end of the said spring being secured to an arm 49 or equivalent support projected inwardly from the outer member 39 of the plow-beam, as illustrated in Fig. 1. An arm 50 is made to adjustably enter each of the tubes 44, pivoted to a plow-beam, and the upper end of each arm 50 is pivotally attached to the block 17, connecting the side pieces 16 of the uprights carried by the axle.

The adjustment of the arms 50 in the tubes 44 will regulate the depth to which the plowshares may normally enter the ground, the locking-pins 46 being adapted to pass not only through the tubes 44, but through the entering arms 50. In order that the arms 50 may be conveniently operated, they are provided with handles 50. The forward end portions of the plow-beams proper are supported in a measure by springs 51, attached to the said beams usually where they are connected and to collars formed upon the vertical sections of the axle 10, as shown particularly in Fig. 3.

In operation as the machine is drawn forward the attachment between the uprights carried by the axle and the plow-beams may be such as to hold the plowshares normally out of engagement with the ground, and the shares may be forced into the ground by the driver exerting downward pressure on the stirrups 43, or the connection between the arms 50 and the tubes 44 may be such as to compel the shares to enter the ground a certain distance, beyond which distance they may be forced into the ground by pressure on the stirrups. lVhen extra downward pressure is exerted upon the plow-beams, the springs 23 will be placed under tension, and when such pressure is removed the plowbeams will be restored to their normal position, and in the event the plowshares should strike an obstruction and the beams are forced upward the springs 48 will be placed under tension, so that the moment the obstruction has been passed the plow-beams will return automatically to their normal position. The extent to which the beams may be lifted is regulated by the adjustment of the collars 13 on the axle.

The forward uprights 10 serve as a brace and prevent the plow zigzagging sidewise, and

the arms 50, connected with said uprights and adj ustably fitted in the sockets 44, serve as adjusters, regulating the depth of running, and also serve, when taken in connection with the uprights 16, as braces for the beam. The uprights 16 and arms 50 are also employed in raising and lowering the plows out of and into the ground. When the arms 50 are carried sufficiently forward to enable them to rest upon the collars 13, the arms constitute a lock, enabling the plows to be carried in an elevated position.

The polygonal sleeve 12 on the axle and the collars 13 are principally employed for regulating the space between the two sets of plow-beams, the members of the axle being separated, and the sleeve and collars also tend to the proper balancing of the frame upon the wheels, being made stationary by the use of the set-screws 15.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A cultivator, comprising a wheeled frame,

'a tongue provided with a cross-bar, plowbeams, each consisting of an upwardly-curved section having its front end pivotally connected to the cross-bar of the tongue, and two zigzag bars pivoted to the rear ends of the curved sections, the inner bar being of greater length than the outer bar, shares a1 ternately arranged on the said bars, and means for independently controlling the up-' upper ends of the uprights, substantially as described.

3. In a cultivator, the combination with the frame, and the axle, of plow-beams, each consisting of a forwardly and upwardly curved section pivoted to the frame, and members of zigzag form connected together and pivoted to the forward section, and springs secured to the plow-beams and to the axle, substantially as described.

4. In a cultivator, the combination with a wheeled frame having its tongue provided with a cross-bar, of plow-beams, each consisting of an upwardly-curved bar having its front end pivotally and adj ustably connected with the said cross-bar, and two zigzag bars of unequal length and pivoted to the rear end of the curved bar, and shares alternately arranged on said zigzag bars, substantially as herein shown and described.
