679,489, dated July 30, 1,901.

Application filed April 3,1901. Serial No. 54,153. (No model.)

To (HZ whom 2'2 nmy concern:

Be it known that I, JACOB Al IVIEBE, acitizen of the United States, and a resident of Adelaide, San Luis Obispo county, State of California, have invented certain new and usefulImprovements in Flows; and my preferred manner of cz'irrying out the invention set iorth in the following full, clear, and exact description, terminating with claims particularly specifying the novelty.

lhis invention relates to agricultural implements, and more especially to that class of devices known as plows; and the object of the same is to produce a device of this character having in the one machine several points of improvement and advantage which i 'iil appear throughout the following specifica ion. 7

To this end the invention consists in the details of construction hereinafter more fully set: forth and claimed, and illustrated in the drawings, wherein- Figure I is a plan view of this machine complete. Fig. II is an elevation of the right side, with Ihe nearer supporting-wheel removed, the furrow-wheel raised, and the.

steering-post deflected slightly. Fig. III is a horizontal section through the steering-post. Fig. IV is a detail showing the parts of the steering mechanism. Fig. V is a transverse section through the machine just forward of the main axle and looking to tlieiear. Fig. "fl is a plan view of a turn-table and. framework which I may use in this connection.

VII is a section through Fig. VI, showing the operation of the catches for holding the in ramble. Fig. fill is a perspective derail View ofone of the catches shown in Figs, "(I and VII.

Referring to said drawings, the numerals l designate the main wheels, each of which is mounted on acrank-axle 2, whose inner extreniiiy is jonrnaled for rotation in the main tubular axle 3. The latter supports brackets -.l, which in turn sustain a framework 5 of snbsmntially circular shape and whose deu. is of construction form no essential part of the present invention. However, I preferably a range a plus-shaped cross 6 on the top of this framework and extend one'of the arms forward, as at 7, while two of the aide arms 8 are carried obliquely forward,

and all three arms are bolted to the headblock 9, in which moves the steering-post. Moving vertically through the head is a rackbar 10, whose teeth engage 'with a pinion 11, mounted. on a shaft 12, 13, meshing with the internal teeth of a basket-gear 14, which turns on a stub-shaft in the head. 16 is a lever pivoted on the stub-shaft and having a thumb-lever 17 engaging exterior teeth on the basket-gear 14, and by manipulation of this lever it will be seen that the rack-bar can be raised or lowered. A latch 18 is moved through a lug l0 pivoted thereto, and the tip of this latch may enter between the external gear it when it is desired to lock the rackhar at any given height. At its extremity said rack-bar carries eyes 21, in which is journaled the steering-post 22, whose lower end is bent obliquely downward and outward, as at 23, andcarries the sharp-edged steeringwheel 2%. To the upper end of this post is attached a laterally-projecting arm 25, which is connected by a rod 26 with a hand-lever 27, moving over a segment 28 and standing adjacent the drivers seat 29. By manipulating this lever the steering-post and with it the guiding-wheel may be swung from side to side, and as its sharp edge'embedsitself in the earth before the furrow is formed it is evident that the plow can be steered as desired. The team is obviously attached thereto forward of the steering-head, and it will be guided by the driver as may be necessary. The steering can occur whether the steeringwheel is caused to embed the earth. siderable extent or less.

At the rear end of the machine is a-sharpedged Wheel 30, intended to embed the earth and Pavel in the furrow, and when it does so it will be clear that it is impossible to change the course of the machine. In order to steer the machine, Lhefurrow-wheel is mounted in hanger 31, pivoted at 32 to the framework, and is a hand-lever movingoverthe toothed segment 34 and connected by a rod 35 with a fork 36, attached to the hanger 31, so that by manipulating this hand-lever the furrowwheel may be raised and lowered and held at teeth of the basket which carries a gearin the head by means of a ham or handle 20 to a conany desired position, and the stee ing is then i done by the wheel 24. Each main wheel 1 will turnit, while .notswin-gingthe turn-table has attached rigidly to its crank-shaft a handlever 37', moving over a toothed rack-bar 38 and standing adjacent the drivers seat, and

the use of these levers, as is-well know-n in the art, is to turn the crank-shafts so that the fiatfaced supporting-wheels l, which rest upon the surface of the earth, will raise or lower the entire machine to such an extent as to embed the plow to the desired degree in the ground or raise the same entirely out of the ground when the machine has to be transported from placeto place. In the present instance I have shown three disk-shaped movement may readily be accomplished by raising the f arrow-wheel at the back, depressin-g the steering-wheel at the front, and then turning thesteeringpost and guiding the team so as to swing the front of'the machine to the right or .to the left, the disks mean while being permitted to remain embeddedin the ground.

ontchanging the direction of the furrow, the

levers 3-7 are manipulated so as to raise the. framework and lift-the plow eutof .thegrcund,

and thereafter the steering of the machine within the .guideway.

In Figs. VI and VII, 1 show one means-of constructing the turn-table and kicking it at one of two'p'ositions within the-guideway 43. Here the turn-.table 42 is plus-shaped like the 'pnrtG-of the framework, and the latter carries the gnideway, 43, in which move the tips of the crossed beams forming the turn-table, thus obviating the necessity for a pivot-bolt.

In the present instance one of said crossed beams is narrow andtwocatchesare provided w-hichare duplicates of each other. Each catch comprises an arm or two arms 4t, pivotedat 45 upon the top of the gnideway and hawingat their outer ends a cross-piece 46,

which at its transverse extremities is bent downward and then outward andohliquely upward into hooks; 47, whereby the. beam approaching from either direction will ride under the nearest hook and into the space between the books, when the catch will fall and hold the turn-table locked. 48 is an arch standing over this catch, and 49 is it hull-crank lever pivoted in the arch, with j due-arm connected by a rod 50 withthe catch.

Through the-other and upper arm of this lever passes a rod 51, having a head 52 at its outer end, while its inner end is connected with one arm of the bell-crank lever 5.5, pivk oted at 56 on the framework and having a When it is desired simply to turn corners or to reverse the machine withfootpiece 5.7 in its other arm. As before stated, there are, two of these catches, and when the operator depresses the footpiece both catches are raised, thus freeing the turntable, no matter which catch previously held it. By properly tur'ning the machine the axial line of the disks is changed, as above explained, and, the drivers foot being removed and the catches dropped as soonms the turntable begins to turn, when the proper point has been'reached the narrow beam is automatically engaged by the other catch in a manner which will be clear. The headed rod 51 obviously slides through the eye in the upper arm of the bell-crank lever &9 when either catch rises to automatically engage the narrow beam of the turn-table. I do not limit myself to this specific construction of fastening means for the turn-table, as others might be employed to advantage, In fact, I desire not to be limited to the exact construction of any part of this machine further than as set forth in the claims below. I I

In use the team is attached and the driver takes his seat. By throwing the main wheels down and setting the guiding-wheel properly the machine can be driven to the place wherethe work is to occur without having the disks enter the ground. Then by raisingthe main wheels the entireframework and disks are permitted to descend. As soon as the machine starts and the furrow is formed the guidingwheel is raised and the furrow-wheel at the fear is dropped into the furrow, so as to make the latter straight. independent setting of the main wheels will be found of advantage, for a reason which will be clear to those skilled in the art. The operation of turning corners-or of shifting the angle of the axial line of the disks to the line of movementhas been described above. The parts may be of any desired sizes, shapes, proportions, and materials, though the. whole is preferably of metal.

In I, I have'shown the turn-table in dotted lines beneath the flooring of the frame- .work, and the flooring is broken away at one point to illustrate a step 444, against which one arm of the plus-shaped turn-table strikes A.

at one extremity of its rotary movement. similar stop is located at the other side of the framework, againstwhich the opposite end of this (here the wider) arm 42 of the turn-table strikes when' it is turned to the other extremity of its movement. This arrangement is obviously much simpler than the one illustrated on Sheet 3, which involves the use of catches and a footpiece, and the stops serve the purpose nearly or fully of the catches, because they prevent the turn-table from turning farther than desired.

Having thus described my invention, what I claim is 1 1. 'In a plow, the combination with the framework carrying the share, and a crank axlehaving two supporting-wheels for said framework; of a steering-wheel at the front In sidehill-plowing the IIO end of the framework, a furrow-wheel at the rear end of the framework, and means for raising one of these wheels, all substantially as described.
