' MOTOR-PLOW.

Y Specification of Letters Patent. Patented J an. 24:, 1911.

Application filed March 27, 1906. Serial No. 308,375.

To all whom it may concern:

Be it known that I, WILLIAM A. DAwsoN, a citizen of the United States, residing at Iola, in the county of Allen and State of Kansas, have invented a new and useful Motor-Plow, of which the following is a.

specification.

This invention relates to motor. propelled machines and more particularly to means whereby the direction of the movement of the machines can be readily controlled, said means being actuated by the driving holder. Another object is to provide a machine of this ty e having tilling devices mounted upon the rent portion thereof, means being utilized whereby the positions of these devices, with relation to the supporting structure, may be conveniently varled by the operator.

Further 'objects are to improve upon the construction and increase the efficiency and utility of devices of this character.

With these and other objects in View the invention consists of certain novel details of construction and combination of parts hereinafter more fully described and pointed out in the claim.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings, Figure l is a plan view of the complete machine. Fig. 2 is a side elevation thereof. Fi 3 is a perspective view of a modified orm of extenslon of frame for use in connection with the maerably rectangular in outline, and having a longitudinally extending beam C secured along the center thereof, said beam coopcrating with a transverse beam B to support the motor K which is of any desired construction.

Alining, transversely extending axles B are journaled within the sides of the frame A and within the central longitudinally extending beam 0, each of these axles being provided with a series of supporting wheels, D, E, F and G. The rims of these wheels are preferably triangular in cross section and formed of segments (see Fi 2) and if desired, pins H may be exten ed radially from the periphery of each Wheel soas to positively engage the ground and thus prevent the wheels from slipping while the machine is being propelled. In Fig. 1, only two of the wheels have been shown provided with these pins but it is to be understood that all, or any desired number mtg be so provided. I

orner posts a are mounted on the frame A and support a top frame 11 on which are arranged longitudinally extending beams 11 on which are journaled alinin shafts A, eachoof which is provided upon 1ts ends, with sprockets A, designed to transmit motion through chains a, to sprockets A- secured to the end ortions of the axles. Each shaft A is provi ed with a beveled gear A", meshing with a gear A, this last mentioned gear being secured upon a longitudinally extending shaft A which is journaled in a supporting frame (1*, located within the to frame 11. A gear A is secured to the sha A and meshes with opposed gears W and which are loosely mounted on an intermediate shaft Q, which is journaled upon the.

top frame 11 near the auxiliary frames (1 A clutch V is feathered on the shaft Q between each pair of gears W and Z and is designed to e actuated by a lever X or Y so as to engage either of the gears W and Z,

to cause one or the other of the gears to rotate with the shaft Q.

Gears R and S of different diameters are loosely mounted on the shaft Q and clutch members T are feathered on said shaft and are loosely engaged by a yoke a formed at one end of a rod U which is pivotally connected to an actuating lever U By mani ulating this lever one clutch member T W1 1 be brought into engagement with the ad'- joining gear so as to lock it to the shaft Q. A counter shaft N is j ournaled on the beams 11 and has gears O and P secured to it, said gears being of different diameters, the smaller gear P being constantly in mesh with the large gear R, while the gear 0 is at all times in mesh with the gear S. A pulley M is secured on the shaft N and receives motion through a belt or the like, from a pulley L secured to the engine of the shaft.

.It will be understood that motion will be locked to it. If the clutch members V are -in the paths thereof will be locked to the shaft Q and will therefore drive the gears A meshing therewith and cause theshafts A and A to rotate. Motion is thus trans-' mitted through sprockets and chains to the axles B. By shifting the clutch members V in opposite directions the rotation of the supporting wheels can be reversed and by shifting the two clutch members simultane ously in opposite directions the two sets of wheels can be simultaneously rotated in opposite directions, thus. insuring quick turning of the machine.

As herebefore stated, it is the intention to place the tilling devices in front of the main frame so that they will be pushed forward during the operation of the machine and be in full view of the operator. In order to mount a gang of ner, a substantially triangular auxiliary frame J is secured to the front end of the main frame .A and the diagonally disposed side of this auxiliary frame has the plows 2 connected to it.

A caster 3 may be located at the apex of the frame and the shank thereof may have a worm gear 4 attached to it, this worm gear meshing with a worm gear 5 secured to one end of the shaft 5. As shown, especially in Fig. 2, this shaft is journaled upon the frame J and also upon the top frame 11 and has any suitable means such as a hand wheel 6, for actuating it.

A winding shaft A may be journaled upon standards A extending from the di agonal side of the frame J, there being flexible connections 1 between the shaft and the standards of the plows 2 so that when the shaft is rotating, the connections 1 will be wound thereon and the standards and plows elevated. The shafts A may be actuated in any preferred manner, as by means of a shaft a having a gear a thereon to mesh with a gear a which is secured on the shaft A". The shaft a may be actuated by means plows in this man-' of a wheel 6 or in any other preferred manner.

The auxiliary frame J is preferably provided with a suitable series of braces so as to enable the same to better withstand the excessive strain to which the frame is subjected during the tilling of the soil.

A frame J such as is shown in detail in Fig. 3 maybe secured to the'front end of the main frame A when it is desired to carry lng arms J 2 for attachment to frame A and may be shaped to meet the requirements of a harvester coupling. This frame J preferably includes heavy parallel bars suitably connected, as at J the connections being formed with openings j for the reception of securing bolts.

Attention is directed to the fact that the combined widths of the wheels D, E, F and G are substantially equal to the width of the area acted upon by the plows 2, the triangular rims 7 operating to. roll the plowed ground and to form ridges.

Various changes may be made in the construction and arrangement of parts without departing from the spirit or sacrificing any of the advantages of the invention.

\Vhat is claimed is A machine of the class described including a main frame, spaced series of supporting wheels therefor, all of said wheels constituting furrow forming devices, radial projections upon one wheel of each series for engaging the soil to prevent the wheels from slipping, a motor, and separate means actuated by the motor for rotating the respective series of wheels.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.

\VILLIAM A. DAl/VSON.
