WILLIAM L. PAUL, OF SOUTH BEND, INDIANA, ASSIGNOR TO OLIVER CHILLED PLOW WORKS, OF SOUTH BEND, INDIANA.

CULTIVATOR.

Specification of Letters Patent.

Application filed February 26, 1909. Serial No. 480,271.

To all whom it may concern:

Be it known that I, WILLIAM L. PAUL, of South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Culti vators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in cultivators, and more particularly those of the gopher type,the object of the in vention being to so construct the cultivator that the gangs of blades can be raised and lowered or adjusted in such manner that they will move in parallelism both vertically and laterally. I v

A further object is to so construct a cultivator of the gopher type that-the working depth of each blade shall be uniform from end to end of the blade. I

With. these objects in view the invention consists in certain novel features of construction and combinationsof parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings, Figure 1' is a plan view of a cultivator embodying my improvements. Fig. 2 is a longitudinal sectional view. Fig. 3 is an enlarged plan view illustrating one of the S-shaped heads and the parts connected therewith. Fig.i4 is a side elevation of the structure shown in Fig. 4, and Fig. 5 is an enlarged detail View showing the connection of the upper end of the yoke.

1 represents .the'frame of the cultivator mounted at its rear end upon an arch axle 2, the journals of which are supported in carrying wheels 3. A bracket 6 is secured to the rear portion of the frame 1 fland to this bracket, a double seat bar 4 is pivotally attached between its ends by means of a pin 5.

The forward portions of the seat bar mempling pin 10 passes through alined holes in the seat bar members and a slot 11in the bracket 8. A vertical pin 13 is pivotally mounted in the pole 9 forwardly of the .bracket 8 and is clamped to arch 15.

Hounds 16 are pivotally connected at their rear ends with the frame 1 and the forward ends of these hounds are pivoted to collars 17 on the lower horizontal portions 18 of the forward arch. A cross bar 19 is pivoted between its ends to the pole 9 in advance of the forward end of the frame 1, and to the ends of said cross bar, depending clevis bars 20 are pivoted. The lower ends of the clevis bars are connected, by means of links 21 with the forward ends of the hounds 16.

Sleeves 22 are loosely mounted on the laterally projecting arms 18 of the forward arch 15 and each of these sleeves has an arm 23 rigidly clamped thereto. To each arm 23 the forward end of a beam 24 is secured and the rear end of each beam 24 is pivotally attached to a lug 25 which projectsfrom the intermediate portion of an S-shape head 26. Each S-shape head 26 is disposed horizontally and carries a gang of blades. For this reason, sockets or'recesses 27 are provided end of the yoke 31 terminates between the rear arch and the tongue in proximity to the curved portion 5 of the seatbar, where it is connected with a coupling 32, the latter beingyin turn, pivotally attached to the rear portion of a link 33. The link 33 is located above the plane of the frame 1 and is pivotally connected at its forward end with said frame. The beams 24 and link 33 constitute superimposed members pivotally connected at their forward ends with the frame and their rear ends are pivotally connected with the cultivator gangs.

With the construction above described, it will be observed that lines connecting the pivotal points A-BCD will form, approximately a parallelogram, and that when a lifting force is applied to the S-shape heads of the cultivator gangs, the latter will be made to rise in parallelism and the long gopher blades will be maintained in horizontal positions.

An arm 34 is secured to and projects forwardly from an intermediate portion of each S-shape head 26 and to the forward end of each arm 34 the lower end of a chain 35 is attached. The .upper ends of the chains 35 are connected with levers 36 and the latter are provided with detents to engage toothed segments 37 secured to the frame 1. By means of these levers and their connections with the arms 34 the cultivator gangs can be raised and lowered or adjusted. It will be observed that the raising and lowering devices are connected with the S-shape heads 26 in advance of the pivotal connections of said heads with the superimposed members consisting of the beams 24 and link 33 and that the said raising and lowering devices also serve to support the cultivator gangs in the positions to which they may be adjusted. Naturally, while at work, there would be a downward thrust at the front points of the blades, but this is met in part by attaching the supporting chains to the arms 34 in advance of the pivotal connection of the beams 24 with the heads 26 and is controlled by the connection of the heads 26 with the link 33 through the medium of the yoke 31.

Foot pieces 38 are secured over the S-shape heads 26 to permit the operator to press the cultivator gangs to their work, and also permit him to shift said gangs laterally in parallel-ism. This latter operation is effected as follows :WVhen the operator upon the seat 7, applies pressure to the right hand foot piece, the seat bar will be moved to the left, swinging the inner end of the pole to the right and change the angle of the axle, and frame, and carry the arch 15 with the pole toward the right in parallelism by virtue of the hounds or links 16, the cultivator gangs being in effect, adjusted laterally and maintained parallel with the line of draft during such adjusting or shifting.

Having fully described'my invention what I claim as new and desire to secure by Letters Patent, is

1. In a cultivat0r,'the combination with framework,-a cultivator gang, and a part projecting upwardly from the cultivator gang, of upper and lower members having pivotal connection at their fprward ends with the framework, means plvotally con-. necting the rear end of the lower member with the cultivator gang, means pivotally connecting the upper member with the upper end of the part projecting upwardly from the cultivator gang, and supporting means connected with said cultivator gang forwardly of the connections between the latter and said members.

2. In a cultivator, the combination with a frame, and beams pivotally supported at their forward ends and capable of free vertical movement on their pivotal supports, a cultivator gang connected by a horizontal pivot to the rear end of each beam, and fleX- ible supporting means attached to said frame and connected at the lower end with the cultivator gangs in advance of the pivotal connect-ion of the latter with the rear ends of said-beams.

3. In a cultivator, the combination with a frame, pivoted beams suspended at their forward ends therefrom, and a plurality of cultivator gangs loosely connectedwith the rear ends of said beams by means of horizontal pivots, of an upwardly projecting yoke connecting the cultivator gangs, a link pivotally attached at one end to the frame and having pivotal connection at its other end with said yoke, and support-ing means for the cultivator gangs connected with said gangs in advance of the pivotal connections between said gangs and the beams.
