PLOW.

Specification of Letters Patent.

Patented Oct. 13, 1914-.

Application filed May 26, 1913. Serial No. 770,060.

.To all whom it may concern:

Be it known that I, Hans SCHLIGHT, a citizen of the United States, and resident of \Valnut, in the county of Pottawattamie and State of Iowa, have invented a certain new and useful Plow, of which the following is a specification.

The object of my invention is to provide a gang plow of comparatively simple construction, provided with mechanism so con structed and arranged that the plows may be moved closer to each other or farther apart from each other, as desired.

More particularly it is my purpose to provide such a plow, in which the plow shares may be manipulated as above set forth for turning corners.v

Still a furtherobject is to provide a plow of the class mentioned in which an additional share is carried for throwing a land while turning corners so that after a few rounds have been plowed the curve of the furrows at the corners forms the arc of a comparatively large circle.

Still a further object is to provide in such a plow, means whereby the distance of the plow shares from each other is automatically of a land.

My invention consists in certain details, in the construction, combination and arrangement of the various parts of the device whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in which:

Figure 1 shows a side elevation of a plow, embodying my invention. Fig. 2 shows a top or plan view of the same, Fig. 3 shows a detail view of the mechanism for automatically regulating the distance of the plows from each other, and Fig. 4 shows a detail view showing the manner in which the arm 63 is jointed.

In the accompanying drawings I have used the reference numeral 10 to indicate generally the main frame of my plow. Extending forwardly from the front end of the main frame' is an additional frame 11. Pivoted to the portion 11 of the frame 11 is a sleeve 12 which carries the axle 13 on which are the front wheels 14:. Suitably mounted upon the frame 10 is a rear axle 15 on which are mounted large traction wheels 16.

Mounted upon the frame 10 is a suitable,

primary source of power 17 which maybe a the shaft 22. Upon the axle 15 are sprockets 30 and upon the shaft 25 are adjustably mounted sprockets 31 by means of the sleeves 32 and set screws The rear axle is designed. to be of the two part type. described in my application for patent, filed April 15, 1912. Serial No. 690,893. Upon the sprockets 30 and 31 are sprocket chains 31.

For throwing the friction disks 23 and 24 respectively into or out of gear with the band 20 on the wheel 19, I have provided the following means. Formed on the disks 23 and 24 are sleeves 23 and 2 Pivotally connected with the sleeve 23 is one arm of a bell crank lever 34, which lever is centrally pivoted onthe frame of the machine.

Pivoted to the other arm of said lever 34 is a rearwardly extending link 36, the rear end of which is pivoted to a 38. Pivoted to the sleeve 24a is a lever 35 which is pivoted at a point between its ends on the frame and has a rearwardly extending handle 37. It will be understood that the lovers 84 and 35 are so connected with the sleeves 23 and 245* as to permit the free rotation of said sleeves with the shaft 22-. By manipulating the levers 38 and 35, the sleeves 23 and 24 and the disks 23 and 24 may be moved inwardly or outwardly on the Shaft 22.

The wheel 19 is slidably but non-rotatably mounted upon the shaft 18. For sliding the wheel 19 toward and away from the cen ter of the disks 23, I have ope-r nected with the hub 47 of the link 48 which is in turn pivoted of the lever 49. The lever i pivoted on the frame of theme pivoted at its other end to a lint: 0. The link 50 is operatively connected with a suitable lever 51. I

Mounted on the engine shaft is a friction wheel, which may be in engagement with the disk ll slidabl mounted on the longitudinally arrange shaft d2. For sliding controlling lever the disk -1 on the shaft 42 and thereby throwing it into or out of engagement with the wheel 40 I have pivoted on the disk 4-1- a link 43 which isalso pivoted to av lever 44;. The lever 4' is'centrally pivoted on the frame 10. ...'oted to the end of the lever 44, opposite to the end thereof to which the link 4-3 is secured, is a link lf which is in turn pivoted to a. controlling lever 46.

Pirotcd to the t'rame, near the rear end thereof, is a lever or bar 58 whici is normally arranged with its longitudinal axis forming an obtuse angle with the longitudinal axis of the machine,- as shown in Fig. 3. At one end of the lever or bar 58 is a right angled rearward extension Near the other end of the lever or bar is pivoted a short link 60. Plow beams 52 are pivoted to thelink G0, to the extension 59 and to the central part of the bar 58. Pivoted to the end of the bar 58, opposite that on which the extension 59 is formed, is a link which extends forwardly in the machine. Mounted on the beams 52 are plow shares 53. The beams are adjustably connected by bars 52, which are pivoted to t e respective beams and are adjustable with relation to each other.

The plows are arranged in gangs, each plow except the front one being in the rear of the plow nextjn front; Secured to each of the plow beams 52 is a chain or other flexible device 57. The chains 57 are wound upon a transverse shaft 5ft. Upon the shaft il is a ratchet 1.01., and. upon the frame 10 is mounted a pawl 102, arranged to coact with the *atchet for holding the plows up. Upon the shaft 54:. is a beveled gear 55 in mesh with the beveled gear 56 on the shaft 4' 3y throwing the disk 4-1 into engagement with the disk 41.0, the shaft 12 may be rotated for raising or lowering the plows by winding or unwinding the chains 57 on the shaft 541. Piroted tothe sleeve 12, on the front axle to the left of the center thereof, as shown n Fig. 3, is an inwardly extending arm Cl to which the link (30 is pivoted.

Pivoted to the sleeve .12, near its right hand end is a forvi'ardly attending arm (2 to which pivotediian arm G3 which normally extends forwardly and is also inclined laterally to the right. At the forward end of the arm 33-h a downwardly extending portion 64 on which is moli/nted a roller 65. The arm ($15 is piv ."l to the arm 62 at 66 to permit the arm (3.; to swing upwardly and downwardly io-prevent latpral moven'ient of said arms nith relation to cachother, and

to limit the downward movement of saidv arn'r'63 a link (37 is pivoted to the-arm (32 and the arm .6].

It will be seen that in the machine, as

shown in the drawing, if th'e'arm 63 is moved it will move the right hand end of the bar 5'8 forwardly or rcarwardly and be to cause the ilows to move toward or away from the middle of the machine T he wheel 65 is designed to travel in the furrow and engage the side thereof. On account ofthe fact that the arm (31 is secured to the sleeve 12 at a point apart from the middle thereof, the draft of the plows would tend to draw the left hand front wheel rearwardly and cause the machine to turn. To overcome this tendency, I have secured to the sleeve 12, at a point spaced apart from the middle thereof, at the right hand side, a contractible coil spring (38, which i's, in turn, secured to theframe 10., For normally; drawing the arm 62 inwardly and thereby causing the wheel (55 to engage the land at 35 the side of the furrow, a contractible coil" spring 69 is secured to the arm 62 and to the sleeve 12, clearly shown in Fig. 3.

Upon the frame 10 is mounted a bracket 70 in which is slidably mounted a vertical 9o bar h'Iounted on the fraine 10 is boll crank lever 73, one end of which is pivoted to a link 74. The link "4 is pivoted to the bar '71. crank lever 73 is a flexible device or chain 75, one end of which is wound aroundthe shaft Tt will he understood that ordinary steerine mechanism may be'usedon my plow for controllieg'thc front wheels; 160

differential may be used which maybe of a y ordinarr construction. in the practical opera tiou ofmy improved plow, when the machine is to be drawn over ordinary ground. the (alpine is started and the members it aiirl 41 are thrown into en-' gag cment. Th plows may be raised and' said members may then be moved out of engagement. The I lever 51 and mechanism connected therewith may be operated to 11 0 more lhc wheel 19 to a point almost opposite 3h center of the friction disks. One of said diws may then be mored by means of the proper mechanism la-r inbcfore descril' cd into contact with the friction hand 20 'and 115.

the chain will be propelled fo'zwvardly or rem'wardly, fl.})!l'l(llll;1' upon avl ich of the disks 23 or il has been thrown) into gear. llrsli lim: the wheel 15) upon the shaft L3,

any desired spared of the narrhiuewnay be obtained.

\s' hcrcinlu-forc explail'icd, it is my desire'to provide a machine in which a single land may he plowed from the outside-bythrowinga substantially continuous furrow.

in plowing "a field. l plow onfto around the entire field, throwinn' the land toward the outside. ()nthe s cond round. the plow 72 will travel in ho open furrow and will he inoperative until, the corners are reached. 1:50

71, which carries a plow share 72.

Secured to the other end of the bell 95'- On going around the corner, the plows 53 will tend to swing together. On the other diand, as thefront axle is turned, the left side thereof will move rearwardly toward the rear axle permitting the arm 61 and the link to mo 61 rearwardly. This will move the pivotal points where the outer plows are connected to the bar 58 a slight distance farther from lhe middle line of the plow than their ordinary position and will tend to hold the plows apart. The plows 53, however, tend to swing inwardly from the furrow and to leave an unplowcd space. As this occurs, the plow enters the ground and cuts out the land that would ordinarily be unplowed at the corner. After this operation has been repeated several times at each corner, a curved furrow is made at each corner instead of one having assubstantially square corner. The land may then be plowed in one great circle until the field is completed.

On account of the construction of the parts heretofore described, .the plow will practically guide itself after the first round. The wheel will engage the side of the furrow and will properly steer the plow. The advantage of a device of this kind can readily be seen. iritera few rounds, a wide curve is made at the corners so that the rest of the field. may be plowed without any sharp turns It will be seen that with my iniprm'ed plow, the field may be completely; turned over and this may be accomplished with a minimum packing down of the plowed ground.

The important parts of my device are of conuj'artivelv simple and inexpensive construction and my plow can built at a coinparatively small expense, After the first round it is practicall elf guiding.

I believe have luced Yer effective transmission mechanis u in the arrangement of the wheel 19 on the shaft lr' and in the placing of the friction band on the wheel on the engine ft of en cam ,trouble with the orms of friction disk trai'ismission.
