WILLIAM L. PAUL, OF SOUTH BEND, INDIANA, ASSIGNOR'TO OLIVER GI-IILLED PLOW WORKS, OF SOUTH BEND, INDIANA.

CULTIVA'IOR.

Specification of Letters Patent.

Patented Sept. 19, 1911.

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 Cultivators; 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,the object of the invention being to produce a cultivator that will admit of easily and quickly raising the gangs either individually or as a pair and also adjusting them for depth relatively to each other or as a pair, and to so construct the mechanism that the results above mentioned can be attained with the use of a single lever and a single latch.

With this object in View the invention cohsists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings, Fi ure 1 is a longitudinal sectional view partly in elevation of a cultivator embodying my improvements. Fig. 2 is a transverse sectional view partly in rear end elevation, and Figs. 3, 4, 5, and 6 are diagrammatical views.

1 represents an arch axle having journals at its respective ends mounted in carrying wheels 2 and upon said arch axle a frame 3 is mounted. In advance of the carryin wheels, a front arch 1 is supported by and depends from the cultivator frame 3, the depending arms of this arch being provided at their lower ends with laterally projecting members 5 with which the forward ends of plow gangs 6 are connected. The laterally projecting members of the front arch 4 are connected, by means of brace-rods 7 with the frame 3 preferably in proximity to the mounting of said frame upon the arch axle 1. A draft equalizer 8 is supported by the forward portion of the frame 3 in proximity to the tongue 9 and from respective ends of the evener bar 8, pivoted links 10 depend,these links being connected with the depending portions of the front arch by means of rods 11.

Somewhat in rear of the front arch 4:, a rock shaft 12 is mountedand is provided at its respective ends with de ending arms 13, the latter being connected y means of rods 14 with the journals of the arch axle 1. Two brackets 15, 15, are mounted at respective ends of the rock shaft 12 and attached to the depending arms of said rock shaft. The upper ends of the two brackets 15 are connected by a transverse bar 16 and this bar is provided centrally between its ends with a standard 17. An evener bar 18 is pivot-ally supported centrally between its ends by the standard 17 and with respective ends of said bar the upper ends of rods 19 are pivotally.connected,the lower ends of said rods being connected with the respective plow gangs, as clearly shown in Fig. 1.

A lever 20 is secured to the rock-shaft 12 or to one of the arms 13 thereof and provided with a latch 21 having a tooth 22 which is normally pressed, by means of a spring 23, into engagement with a toothed segment 24 secured to the cultivator frame 3 adjacent to the rock shaft 12. A rackbar 25 is attached at its upper end to the evener bar 18 near one end of the latter and passes through a guide arm 26 secured to the lever 20. The rack-bar 25 is so disposed that'it will be engaged by a tooth 27 on the latch 21.

It will be observed that the rock shaft 12, brackets 15 and cross-bar 16 constitute a rocking frame and that the evener bar which is connected with the respective plow gangs is mounted upon and carried by this rocking frame.

l/Vhen it is desired to raise one of the gangs, the latch 21 will be operated by means of a latch lever 28 to disengage the teeth 22 and 27 from the racks 24 and 25, thus permitting the shaft 12 to be rocked by means of the lever 20 and the rocking frame to be moved upwardly. The raising of the plow gangs will be controlled by footpressure applied thereto by the operator and when the rocking frame is raised, as above explained, the gang upon which the least amount of foot pressure is exerted will rise While the other gang will remain in its lowest position. The two gangs may be locked in such relative positions by the engagement of the tooth 27 01 latch 21 with the rack 25. Should it be desired to adjust the one gang a trifle lower in the ground than the other, this may be accomplished by releasing the latch bar 21 from the rack 25 without moving the lever 20 and then pressing with the foot upon the gang to be lowered. The diagrams, Figs. 3-6 show approximately the relative positions of the evener bar and rock shaft under various conditions. In Fig. 3 the position of the parts are indicated which will occur when the gangs are down to cultivate at even depths, at which time the rods 19 which connect the evener bar 18 with the cultivator gangs will be disposed as indicated by the dotted lines.

In Fig. 4 the position of the parts are shown as when the gangs are both up and level. In Fig. 5 is shown the positions which the parts will assume when the right hand gang is down and the left hand gang is raised, and in Fig. 6 is shown the posltion of the parts when the right hand gang is ralsed and the left hand gang is down. i It will be noticed that the arc trav- I claim as new and desire to secure by Letters-Patent, is,"
