Application fi1ed.0ctoberi30,1922. Serial No. 597,871.

It is known in the cultivator art that when the beams carryingthe cultivating elements are raised from or lowered into op crative relation with the soil the center of gravity of the implement is changed, thereby necessitating the provision of means change in ordmthat the proper balance of the implement may be preserved in all positions of the beams and tillage elements relatively to the ground. 7

One of the important purposes of this invention is to provide HIGZIHSfOl balancing the parts when the tillage elements are in either raised or lowered position without necessitating for this purpose the utilization of carrying wheels movable forward and rearward relatively to the frame, thereby avoiding the necessity of the provision of a more or less complicated construction for effecting such movement of the wheels and permitting the use of a frame COIlStILICtlOll of more rigid character.

It is also known in this art that the manual force required in the raising of the til lage elements and their supports should be reduced as much as possible and it is an other purpose of this invention to provide a novel combination and correlation of elements whereby the drivers seat is movable to utilize the weight of the driver in the lifting of the tillage elements and their supports out of ground working position.

Simplicity of construction is always desirable and, accordingly in-y'invention has for a further object the provision "of means by which both of the foregoing purposes may be carried into effect by a very simple and practical construction, and accordingly my invention further consists severally in novel combinations and correlations of elements whereby: (1) The seat support is pivotally mounted to have simultaneous for ward and downward movements while the tillage elements and their supports are being raised, obtainable from the operation of a single actuating element suitably connected to the frame and to the seat support and to the supports for the tillage elei'nentsz and (2) the said actuating element is also operableto adjust the tillage'elements and their supports and may be locked to hold them in various adjusted tillage elements.

7 ositions to regulate the depth of penetration of said In the accompanying drawings I have ilwithout departing from the spirit of the invention as defined by the appended claims.

In said drawings, wherein like char cters of reference denote corresponding parts in the several views I p I 1 is a side elevation showing'the relative positions of the parts when the beams and tillage elements are in working position. i I

Fig. 2 is -a like view showing the relative positions of said parts when in trans port position. v

Fig. 3 isa perspective'view with parts broken off and the tillage elements omitted. The cultivator beams A and B constituting supports for any suitable construction oftillage elements A, B may be of any suitable construction. These supports are pivotally connected at a and Z), respectively to an appropriate part of the main frame of the implement to permit them to be adjusted for depth of penetration and to be lowered and raised into and out of ground working position, by the means hereinafter set forth. v

The main frame may be of any suitable construction an'dis mounted upon suitable carrying wheels C, D. As here exemplified the frame comprises two longitudinal bars 10 and 11 suitably spaced apart and converging at their forward ends to receive be- *tween them and to support a tongue 12 to the sides of which they are secured by the through bolts 13. These bars are shown as supported at their rear endsby a cross member 14 having downwardly extending ends forming vertical members 15. The bars 10 and 11 are also cQnnected'neai' their forward ends by a cross member 16of suitable constructionand which is suitably secured thereto. Inclined braces 17 eiitend rearwardly from the cross member 16 to the lower ends of members and are rigidly securedto and brace these parts of the frame against relative movement. 'The illustrated connection of the frame and tongue is such that these are rigid and eta- 'tionary with relation one to the othen In the construction illustrated by the drawings the connection between the lower ends of the brace members 17 and the vertical members 15 is effected by brackets 18 mounted on the members 15 and suitably secured to the members 17. Spindles 19 are arranged at the junction of the members 15 and 17 and are suitably supported and upon these spindles the wheels C and D are journaled.

The letter E designates a drivers seat which is mounted upon a suitable support F having movement bodily in a forward and downward direction simultaneously with pivotal movement of the supports A, B, of the tillage elements in an upward direction, and, conversely, in a rearward and upward direction simultaneously with downward movement of said supports A, B. The described movements of the seat sup-port F and supports A are, of course, relatively to the main frame, supporting wheels and tongue, in the illustrated embodiment of the invention.

The seat support constitutes a lever which extends longitudinally of the frame. It is preferably formed by a pair of spaced bars and its preferred location is below the plane of the main frame and with its forward end in advance of the vertical plane of the axle spindles 19 and its rearward end, upon which the seat is mounted, rearward of said plane. It is here shown as composed of a pair of spaced bars 20, 20 each having a pair of upwardly extending elements 21 and 22 which substantially form upward projections from the seat supporting lever, to the side bars of which they are rigidly secured in any suitable manner. The projections 21, 21 are connected by links 23, 23 to fixed brackets 24, 24, which brackets depend from the frame members 10, 11, respectively. The upper ends of the projections 22, 22 are pivoted at 25 to toothed quadrants 26, 26, which are pivotally mounted on the frame member 14 and are connected to each other to move simultaneously, being here shown as secured to opposite ends of a sleeve 27 rotatably mounted on the member 1 1'. Hand levers 28, 29 having ordinary spring latches 30, 30 connected by links 3 30 to suitably arranged latch- operating handles 31, 31 are mounted in such relation to the quadrants 26, 26 respectively, that they may be locked to said quadrants and either one'the lever 28 in this instanceoperated to turnthe quadrants pivotally, or may be released from their locking engagement to the quadrant so as to be operable relatively to the quadrant. As here shown, these hand levers are pivoted at 32, 32 to the quadrants. They are provided with projections 33, 33 connected by links 34:, 34

to the supports A and B carrying the tillage elements A, B. Another quadrant 35,

having teeth at its opposite ends is fixedly secured to the frame-member 1 1, and a dog 36 to engage the teeth of said quadrant is pivoted at 25, to the adjacent quadrunt26. This dog is controlled by a handle 37, which is connected thereto by a link 38 and is suitably pivoted to the hand lever 28, adjacent t a handle 39 projecting laterally from the lever 28.

It will be seen that when it is desired to adjust the supports A, B and tillage elements A, B to regulate the depth of penetration of the tillage elements into the soil, the hand levers 28 and 29 are grasped adjacent the handles 31 and the latter are operated to release the hand levers from their locking engagement with the quadrants 26. The hand levers-are then moved on their pivots 32 relatively to the quadrants 26 and (the links 38 and the pivotal connection of the handles 37 to the hand levers permitting this movement notwithstanding the dog 36 is at this time engaged with the adjacent quadrant 35) thereby raising or lowering the supports A, B, according to the direction of pivotal movement given the lovers 28 and 29. \Vhen the desired adjustment has been accomplished the levers 28 and 29 are locked to their respective quadrants by releasing the handles 31, the springs (not shown) in the latches 3O operating to engage the latter with adjacent teeth of the quadrants, respectively, and thereby holding the parts in the positions to which they have been set.

hen it is desired to raise or lower the tillage elements and their supports from or into working relation with the soil, the handles 39 and 3?, carried by the hand lever 28, are grasped and the handle 37 is operated to release the dog 36 from the quadrant 35. Force now applied to the hand lever will operate through the connected quadrants 26, the projections 21 and 22 and the links 23 to move the seat support bodily, in a downward and forward direction or in an upward and rearward direction, as the case may be, and will also operate through the projections 33 and links 34 to move the supports upward simultaneously with downward and forward movement imparted to the seat sup port, or downward simultaneously with upward and rearward movement imparted to the seat support.

Thus it will be seen that I have provided a most practicable means for carrying into effect all of the before mentioned several purposes of the invention.
