To all 'whom t may concern.'

Be it known that I, WILLTAM CLow, -a citizen of the United States, residing at Inde pendence, in the :county vof Jackson and State of Missouri, have invented certain new and useful Improvements in Autoplows, of which the followingI is a speciication. My invention relates to auto plowsand the present invention is a division from a parent application filed Mar. 2, 19,11, Serial Onefobjectof the invention is to provide a motor driven plow having two tractionwheels so located as to obtain the maximum weight thereon and travel upon the com-'- paratively rm subsoil at the bottom of the furrows turned by the plow.`

A further object is to 'provide novel mech- .aIlSm Ol' Steering one 0f the traction-wheels and adjusting the same vertically to control the depth of the plow-shares in the soil.

Other objects of the invention will herein-v after appear, and in order Vthat said invention may be fully understood, reference will now be made to the accompanying drawings, in which: y i

Figure 1 is a side elevation of a gang plow constructed in accordance with my invention, the motor being removed. Fig. 2 is a plan view vof my improved plow with a portion of the platform broken away and the motor removed. Fig. 3 is a rear elevaltion of the steering traction-wheel .and a sub` soiling appliance arranged in the rear of said traction wheel. Fig. 4 is a section on line I V-IV of Fig. 2, showing the steeringtraction-Wheel, part of the drive gearing therefor, and the subsoiling device. Fig. 5 is an enlarged vertical section on line 4.V.-V of Fig. 2 of the steering tractionwheel and its axle mounting. Fig. 6 is adetail vertical elevation of the steering chain shaft and worm-wheel, 'the bearing of the .shaft being in section, Fig. 7 is a detail section on line VII of Fig. 2.

- 1 designates the main frame of my autoV being substantially rhom-l plow, said frame boidal in plan' and preferably constructed .of

metallic beams to successfully withstand the variousstraiins imposed thereon. Frame 1 is covered by a main platform 2, having an extension `3, upon which a seat 4 is'mounted for the convenience of the operator.l Frame is supported by a rear tractionwheel 5, a

small land-wheel 6- on the` Seme Side 0f th@- `frame as said'traction-wheel 5, and a front steering traction-wheel 7 arranged diagoand lowering relatively to the frame, said Amechanisms being operable simultaneously by a single lever 9, or individually by separate levers 9a. As said mechanisms are fully set forth in the parent application, a detail description hereinl is deemed unnecessary.`

The mechanisms just referred to are not designed forholding the plowshares in in- 'termediate working positions; but means have been provided for that purpose, which shift the main frame 1 up and down at the forward end thereof. Referring morel particularly to Figs. 2 and 5, it will be seen that a yoke 10 is secured vertically tothe forward right side of the main frame 1. Connecting the ends of said yoke is a shaft 11 upon which is swiveled and slidablymounted an axle-block'12 carrying an axle 12, upon which the front traction-wheel 7 is mounted. Integral with the inner end of axle-block 12 is a forwardly-extending bracket 13. A .hand-lever 1,4 is operablysecured to the upper end of the yoke 10 bya pivot 15, and fulcrumed' at 16 upon a link 17 pivotally secured at its Alower end to a lug 18 projecting rearwardly from the axle block 12. Lever 14A is locked in any of its adjustedpositions by a notchedsector 19,

secured to platform 2. vSutlicient looseness l exists at the pivotal points-16 and 18, to allow wheel 7 to turn to theright or left without turning lever 14 therewith. As the yoke 10 is secured to the main frame 1, it is apparent that when the. lever 14 is operated, it will raise or lower said yoke and saidframe, the shaft'- 11 sliding through the ias v 20 is a'block 22, vto which a hand-lever 23' provide with Itwo s et- wheels 28 and 29.

v interm block maxed to the adjacent "side ofv the main ,frameL Fixed u on the top of axle is operably secured b a pivot 24;.1'fandtsaid hand-lever is pivota y secured at itsforward end to a downwardly-extending link 25,L pivotally connected to the adjacent side ofthe main frame 1.

From the foregoing constructionit is 0bvious that the land-wheel 6 may be adjust- -ed vertically b .means of .the hand-lever 23, hence -when said land-wheel. 6 is raisedyupon' theland,4 the pivot 24 becomesthe of the hand-lever, so that theframe-l unsyf;

4be raised or' lowered and thusregulate'` the ,depth of the plow-shares. After frame ".1

, has been adjusted-the hand-lever 23 is'locked from accideital movement/by a sector. 26.- By means of the'hand-levers 14 and A23,y the: traction-wheel 7 and the land-wheel 6 may be'adjusted to raise or ..lower thegang of,l plows independent of the movements' i. arted by the mechanisms controlledfby evers 9- and 9. f

Sprocket-wheel 38 is fixe upon a short shaft 40journaled in bearings 41 and connected by a universal joint 42 to a tubular shaft 43.

Slidable in shaft 43 is a square or splined shaft-44, connected' by a universal joint 45 with a short shaft 46 journaled" in the forward emi of.. bracket 13 and upon which the pinion 37 isv iixedly-mounted.
