' MOTOR- PLOW.

noiae'se.

To all whom it may concern Be it known that I, DANIEL B. HILL, a

citizen of the United: States, and residentof Grayville, \Vhite county, Illinois, have invented certain new and useful Improvements in Motor-Flows, of which the followto the accompanying drawings, forming a part hereof.

My invention relates to improvements in motor plows and, is especially directed to that class of plows which are knownas gang plows and are driven and steered by a motor carried by the frame thereof.

The primary object of my invention is to construct a frame, for carrying a number of plows, havmg'cut away portions which permit of the turning of the whole structure in a minimum of space.

A further object of my invention isto construct a plow of this class in which the propelling and steering is accomplished by the employment of a motorcarried by the plow frame.

For the above purposes my invention con sists in certain novel features of construction and arrangements of parts as will be hereinafter more fully described, pointed out in the claims-and illustrated by the accompanying drawings, in which:

Figure 1 is aplan of the plow, the operators platform and cab being removed; Fig.

2 is anelevationj-of the complete plow; Fig. 3 1s a transverse, vertical, sectional elevation taken approximately on the. line 3+3 of Fig. 1; Fig; 4 is an enlarged, detail, sec

tional elevation taken on the line H of Fig. 1; Fig. 5 is a detail plan partly in section illustrating the means wherebyfthe plow may besteered either'by' hand or by the 'motor; Fig. 6 is a vertical, sectional elevation taken on the line of Fig. Referring by numerals to the accompanying drawings: 1 designates the frame proper which is. substantially rhomboidal' and at'feach of its side margins is provided with a semicircular portion 2, the semicircular portion, at'the right hancLside of the frame, being in advance of the left hand semicircle, and at the forward end of the frameithere is an extension 3..

1' and 5- designate the supporting and driving wheels which are of any ordinary construction and each of which, carries a bevel gear wheel 6; For connecting the Specification of Letters Patent.

wheels l and 5 with the frame there are the bear ng plates 7 which project laterally g Patented Mar. 5 ,1912. Application filed May 9, 1910. Serial is. 560,194.

wheels 9, each of which is interiorly ,1

threaded for the engagement with andsupporting of the threaded uprights 10. Con-- nected with and preferably formed integral with the threaded uprights 10 are thebifurcated members 11 which embrace the bearing blocks 12 for the stub shafts 13 which support the wheels 4 and 5.

As shown, each of the housings 8 incloses a worm lanormally in engagement with the gear wheels 9, and 15 designates cranks for the moving of said worms for the turning of the gear wheels 9 to raise and lower the frame over the threaded uprigl'its 10. For supporting the rear end of the frame there isa caster wheel 16 rotatably carried on a stem 17. Arranged at'the apex ofthe frame at its rear end there is a housing 18, which housing is provided with integral wings 19 for attachment to the frame 1. The housing incloses a rectangular sleeve 20 having on its forward face teeth forming a rack 21- which sleeve embraces the stem 17 and is adjust-ably secured vertically relative the stenrby means of the collars 22. Arranged withm the housing 18 1s a gear wheel 23 mounted upon ai'shaft 2% which extends through the housing, and carried by a shaft within the housing and not shown is a gear and worm connection with the shaft 24 manually operable by a. crank 28. ,By this" means the r'earmost end of the frame may be raised or lowered as the forward end is raised or lowered over the threaded up rights 10, as required for different depths of plowing, but which means I did not claim in this application.

For driving the Wheels 1 and 5 there is a, motor 29 preferably a gasolene engine which is carried by the extension 3 of the frame. with a radiator 30 of ordinary construction, the connections between the motor and radiator being not shown. Carried by the Themotor as shown is provided frame 1 is a transmission gearing box'31 which is of ordinary construction and is connected with the engine shaft 32 inan ordinary manner. Extending from the transmission gearing box to a point adjacent the right hand side of the machihe frameis a shaft 33having on its end op 40 with a locking member on theengine shaft-- posite the box a bevel gear Wheel 34 which meshes with a gear wheel 35 carried on a shaft. 36 arranged at right angles and beyond the shaft 33.

' Extended vertically from the plates 7 are the bearing blocks 37 and intermediate in the ends of the bifurcated members 11' and at their upper ends are supported by bearings 43 formed integral with-the bearing blocks 37. Each of the wheels 41 is feathered to a shaft 42.

' shafts 42 are the bevel gear wheels 44 secured against rotation relative the shaft and arranged to mesh with the bevel gear wheels 6 carried by the' guide wheels 4 and 5.

' To impart motion to the shaft'39 there is a sprocket wheel 45 embracing the shaft 39 and a sprocket wheel '46 carriedby the shaft 36 and these two sprocket wheels are connectedby the chain 47., Thus, as the engine is operating, the motion therefrom, through the transmission gearing not shown), rotates the shaft 33 ,which through the me dium of the gear, wheels 34 and 35, sprocket wheels 46 and 45 and chain 47 motion isim-' parted to the shaft 39. As the shaft 39 is rotated the driving wheels 4 and .5 are driven through the medium of the bevel g ar Wheels 40, 41, 44'and 6'. Itis to be understood in this connection that the transmis v sion gearing is provided with the' usual means for reversing its movement -well as to throw a clutch into or out fof'en'gagement as required,and all of which is not shown for the reason that any common form.0

such means may be employed.

Tw'o vforms'of steering devices are employed, one. of which is operated solely by 4 hand and the other arranged to be operated by the motor. V

The means whereby the machine may be steered manually comprises a post-48 which is arranged about centrally of the frame of the machine, at the top of which is fixed an ordinary hand wheel 49'and at or adjacent the bottom of the post is a worm 50 which is keyedor otherwise secured to the shaft. The post is maintained in a, verticalposition by means of bearings'51 carried by a housing 52. Extended through the housing is a horizontal shaft 53 upon which is a worm wheel 54 in mesh with the worm 50. Secured to the shaft 53 and extending downwardly at right angles to the shaft is a lever '55. Extending rearwardly from each of the shafts42 beneath the bearing blocks 12 for the stub shafts 13 is an arm 56 which.

Carried by the arms are connected with a rod 57. Pivotally connecting the arm 56 with the lever 55 and actuated by the steering post is connecting rod 58. By the means just described the two main driving and supporting wheels are moved to steer the frame by a manipulation of the hand wheel 49. v

vFor the steering of the caster wheel 16 simultaneously with the steering of the wheels 4 and 5 I have provided an arm 59 extended laterally from the stem 17, and

carried by the frame of the machine is a bell-crank lever 60 and .pivotally connected with one end of the lever 60 and with the arm 59 is a rod 61-. The oppositeend of the bell-crank lever 60 is connected with the arm56 by the 1Od62. Thus,'as the machine is steered, the various connecting devices operate the drive wheels in opposite directions relative the caster wheels. By rea- .'son of the bearings 37 and 38 the shaft 39 is supported in planes wholly above the drive wheels so that the drive wheels may operate beneath said shaft.

For connecting the steering apparatus so that it may be operated by the motor I have provided a bevel gear wheel 63 on the transmission gear shaft 33. Supported on a shaft carried in bearings 64 pendant from .the frame ofthe machine there'is a shaft '65which' carries a bevel gear wheel 66 meshing'with th'cgear wheel 63. Keyed or otherwise securedto the shaft 65 i's'a pair of connected ffriction disks 67 Supported in a hearing 68, which is arranged between the frfetion disks 67, is'a shaft 69 and keyed or otherwisesecured to the shaft 69 is a friction.disk 70 arranged-for engagement with eitherione of the disks 67. The shaft 69 is extended through slots -71 formed in the alls oftgli'e' housing 52. -Embracing the shaft within.thelhoi 1sing is a worm 7 2 arrangedffdr -en'gag ement with the worm 50 carried by'the steering post. 'The bearing 68 justreferred to i's*clearly'shown in Fig.

6 and is of the type which permits slight lateral play-of the entire shaft 69.

For normally holding the worm 72 out of engagement with the worm 50 of the steering post there is a collar 7 3'to which is connected a contractile coil spring 74.

For moving the shaft 69 to place the worm 72 in mesh with the worm 50 of the steering post there is a bell-crank lever 7 5 carried by a bearing 76 projecting down wardly from the frame 1. One arm of the lever 7 3 is connected with the collar 73 by means of the link 77 and the other arm of the lever 75 is connected with a foot lever. not shown, by means of the link 79.

For varying the speed of the steering device the disk 70may be moved toward or away from the centers of the disks 67 by means of the bellrerank lever 80, one end 'of which is bifurcated and arranged to engage a pin 81 carriedby an integral part of the disk 70, the other end of the lever 80 is connected with a rod. 82 which is connected with anylsuitable operating lever (not shown For controlling the direction of the steering means the dlsks 67 are movablelengthwise relatively the shaft 65 so that they will engage atdi'fterent times, opposite'sides' of the periphery of the disk 70. For moving 1 the disks 67 as above described there is a bell-crank lever 83, one end. of'which is bifurcated to straddle a pin 84 carried by an integral part of the disks 6'? and to the 90p posite end of'the lever 83 is a rod 85 connected with a hand lever,- not shown, provided with a pawl and segmental rack for holding the disks 67 in various set positions.

' cording to the-connection made between the I by the transmission gearingnot shown in engine and transmissiongearing shaft 33 detail. From the shaft 33 motion is imparted to the drive shaft 39 through the bevel gear wheels 34 and 35 and the sprocket gearing 45, 46 and 47. From the shaft 39 motion is imparted to the drive wheels through the medium of the bevel gears 40, 41 and the bevel gears 44 which mesh with and rotate the bevel gears 6 carried by the drive Wheels, By reason of the locationof the shaft 39 in a plane some considerable distance above the machine frame proper the-wheels 4 and 5 may operate beneath said shaft as required in steering the machine. As previously stated, the machine is normally in condition to be steered manually by means of the hand Wheel 49 which rigidly connected with the steering post 48. As the hand wheel is turned in eithe' direction, to the right or left, the wheels 4 and 5 and caster wheel 16 are turned through the medium of the levers 56 for the wheels 4 and 5 and lever 59 for the caster wheel, which levers are connected :by suitable rods with the steering post. By this arrangement the wheels 4 and '5 are simultaneimsly turned in/ the same direction while the caster wheel ,is turned in an'opposite direction, thereby causing the entire machine to be turned completely about in a miuinuim of space, as the wheels 4' andfi operate in the cut awzty portions in thesides of the frame. f

If, for any reason, 'the manual steering is diflicult or cannot lfe accomplished .in the required time the operator may connect the steering apparatus with the motor so that the steering may be accomplished by. the

motor. When the machine is steered by the motor the operator can direct the course of travel of the machine by. the moving of the friction disks 67. By moving one of the disks to engage with a cotiperating disk the machine is directed to travel to the right and by moving the said disk away from the cooperating disk andplacing the opposite disk 67 to engage with the coiiperating disk the machine is directed to travel tothe left.

The speed of the steering device may .be controlled by moving said cooperating disk to- Ward or away from the centers of. said disks 67.

By means of the threaded uprights 10 and the worms 14 the wheels 4 and 5 may be, if desired, vertically adjusted independently of each other, as required for causing one wheel to ride over the land and another wheel to ride in a furrow or vice versa, or

for leveling the entire machine to travel evenly over differential inclined lands.

I claim: 1. In a machine of the class described, a substantially, rhomboidal frame, a substantially semicircular cut away portion in each side margin of the frame, one in advance of the other, a steering wheel, located for movements when steering, in each of said cut away portions, a wheeled support for the rear end of said frame, connections between all of said wheels where the first mentioned wheels may be turned i the same direction and the wheelednsup t for the rear of the frame turned in an opposite direction, manually perated means for steering all of said w eels, a motor, and means for connecting sa dmotor with said manu- I ally operated steel 'ng means at times.
