To I?! whom it iimy concern Be it known that we. Jenn K. UNDER- woon, J'omi. B. Unncnwooo, and Guonon T. Uwonnwoon, citizens of the United States, residing at Syracuse, in the county of Ha1nilton and State oi Kansas, have invented a. new'and rselul Plowingillachine, of which the following is a. specification.

lur invention relates to a disk plowing machine equipped with motive power and obtaining traction bye traction wheel which follows in the "furrow made by the last disk and aims to provide a. plowing machine which at the same time will obtain suliiisient traction to suliice for its ellicient operation and providing neans for obtaining the ready adjustment of the machine to a suitable tractor for other purposes. Upon a careful consideration of the drawings wherein is disclosed the preferred forn'i of my machine, it-will he recognized that this is very simple and consists of but a few parts whereby the same may be manufactured and placed upon the market at a minimum cost. in devices 01 this nature, weight has to be given a coir siderablc consideration in View of the fact that this essential for obtaining sufiicicnt traction. While our iIl'VGDlJlOT! disclosed herein appears to be very light, it is thought that the combined weight of the diil'erent parts and also of a motor will give the required weight to the disks and to the rear tractionwlieel and thereby assure the ellicient working of the machine.

Bydevising a machine consisting of but a few parts, we have attained several ohjccts, namely, a machine wherein the dillercut parts can hexreadily removed and replaced by others by the operator; one where in all the parts can be quickly cleaned without (lisinemhering-the entire machine. By obviating the numerous superfluous parts the cost of mai'iufacture is greatly reduced and by the provision of a solid framework and only a few parts carried thereby, the danger of the machine. or the parts thereof getting out of order is obviated.

Broadly our invention consists of a. body portion which will be hereinafter termed as a supporting structure which is supported at its forward end by a pair of comparatively small Wheels and its rear end by a single traction wheel, the traction wheel be ing rotated throughthe medium of suitable gearing connected to a motor carried upon Specification of Letters Patent.

the body portion. A. rod carrying aplurallty oi CllSliS 15 carried by the n'iacl'iine and disposed. at a substantially obtuse angle 1 J I thereto so that when the machine 13 in operation the traction wheel will. follow in thc furrow formed by the last disk. By the pro vision of the number of disks, it is apparentv considerable extent.-

Taking the above mentioned objects in view and carefully considering them in men of the foregoing, it will he recognized that the machine which we have provided over comes the numerous heretofore existed and provides simple, el licient and inexpensive machine which can be easily operated and transported from place to place.

W 1th the above and other oogects new, our invention relates to such details l construction and in the arrangement and coinhination of the several parts as will be here inaiter fully described pointed out in the appended claims.

In describing our invention in detail, reference will be had to the accon'ipanying drawings .wherein like characters denote like or corresponding parts throughout the several parts, and in which Figure l is a plan view of our invention. Fig. 2 is a side 3 iso detail View.

is a fragmentary rear end eleyational viei of our invention showing to advantage the manner of sup porting the frame from the rear axle.

in the accompanying drawings wherein is illustrated the preferred form of our invention, the numeral l0 designates the hotly portion or supporting structure which is carried at its forward end upon braces 11. the latter having engagement with an axle 12 as shown at 13 with. the body portion as shown at 14. This axle is then in turn supported through the medium of the wheels 15. The body po tion above referred to and as will be appreciated upon reference to'the obviating the use or operate the disks as set: ii only a light l'urrmv is to he opened, the disks can be drawn up to'a (litliculties which have elevation thereoinnd Fig.

a d specifically 55 jtheyaxle 19, for theaxle and the which is substantially U shaped as shownat 17, the latter having ing a 'gear wheel I'therethrou fh and 26 and is su ported are, fixedly carried upon a sleeve 31,

"that will be hereinafter set forth. The rear end of the body portion carries a brace 16 engagement with an axle 19 carrying a traction wheel 20. For the purpose of yieldingly supporting the body portion upon the axle 19, we have provided the coil springs 21, which are disposed about the connecting bolts 19 on the enlargement 50 and the sleeve 63 of the brace rod 66 and serveto hold the outer ends of the U-shaped brace 1? in spaced relation to the axle 19. It willbe obvious that the respective ends of the'spring 21, bear against the points of sccurement of the bolts and the outer ends of the U shaped brace 17, which brace is held in place with the spring by means of the nuts 21, screw-threaded on the outer ends of the bolts 19. An engine QQcarrying a fly wheel 23 at one side thereof is disposed upon the body portion and secured in'place by any suitable means.

cross piece 2e1- is also carried by the body portion and disposed adjacent the engine, it having a pair of parallel spaced apart arms 25 and 26 respectively projecting there.' from, the latter arm having the crank shaft of the engine as shown at 27 journaled supported through the .mediun'ior bushing 28. The crank shaft extends as above set forth through the arm I upon the arm" 25 through the medium of the cup shaped member the latter serving as-a socket. The ii" a wheel and pinion 30 and 31 respectively which sleeve is slidably but non-rotatively carried 'ppon the crank shaft, the pinion bei'ng'in engagement with another gear wheel 32 on the sub-shaft 33 as is shown.v The sub-shaft 33 is journaled through the arms 25 and 26 and carries aside from the gear wheel Another shaft 36 is iournaled through the body portion and extends through the arms 25 and 26, it carry- '37 intermediate its end which meshes with the pinion 35 as is shown, for purpose of transmitting motion to the shaft 36. A sprocket wheel is carried upon the shaft 36 and has in engagepinions 3t and 35.

.ment tl' /rewith a sprocket chain 38, the latterialso engaging a sprocket wheel 39 upon the purpose of rotating traction wheel 20 carried thereby andthereby propelling the machine. Another 'sprpc ket wheel is also carried upon the shaft Y36 and receives a second sprocket chain- 40, this sprocket chain engaging a sprocketphain il-on the axle 19 so as to aprveuas an auxiliary propelling wheeiand therebv insuring the efficient Operation of the device.

38 and 4-0 with the cooperation of .its front end with an opening the reception of the axle.

It is now apparent that when the engine is started motion will be transmitted from the crank shaft to the subshaft 33, from the pinion 35 to the gear wheel 37 on the shaft 36. 'Through the shaft 36, the motion is transmitted at each end to the axle 19 through the medium of the sprocket chains the sprocket wheels 39 and 41. By this arrangement it'is apparent that the"pr opelling means of our invcntionis very simple and that each of the parts is disposed to be easily adjusted by'the operator so that he can replace different W orn parts by'new ones if he so desires. 1

A red 42 is provided which carries thereon a plurality of concavo-convex disks 43, the latter being fast upon the rod. The forward. end of the rod 42 is supported upon the axle 12 through the medium of an arm 44;, which has engagement with the rodthrough the medium of the nut and bolt.

arrangement 45, and which is provided at ception of a lug 46 the latter being carried upon an adpistable sleeve 47. disposed about the axle The adjustability of the sleeve can be had through the manipulation of the By the set screw 18 as is clearly obvious. provision of the adjustable sleeve, it is ap-- parent that the position of the rod and disks can be adjusted to vary the width of the furrow opened by the diiferent'disks. The rear end of the rod 42 is supported upon the axle 19 through the medium of a standard 19, the latter having engagement with the rod'as is clearly shown and being provided with an enlargement 50 at its rear end which is in turn provided with anopening 51 for The standard l9 also carries intermediate its end a pair of oppositely extending brackets 52 which support the friction rollers 53 which are in engagement with a sprocket chain 54 operating about a wheel 55 on the rod 42 and extending for'engagement with a companion wheel 56 carried fast with the sprocket wheel 39 on the shaft 19. this arrangement, it is apparent that as the traction wheel 20 is operated-that motion will also he transmitted to the disks whereby they will be revolved in the well known manner.

As the arm 4-1, is pivoted to the axle 12, and. as the standard 4.9, and the brace rod 56 are loosely connected to the shaft 19, we have provided a simple means for raising and lowering the disk rod 42, which in this instance consists essentially of cables 58 and 58, the former being secured tpthe arm by means of a link 57, operates. from a friction roller 59, carried upon the extending brace rod60, and secured theretoasshown atfit; The cable 58,.now extends acrossthe' entire body of the machine andnaloout-av fltic'tigin roller 62, secured to the far sides-0f ths body for the rea portion as is shown as cable t fllisse 115 ii cured to the standard 419' by means of a link 57 and operates fr oni a roller 59 secured to "the side of the body portion 10, as shown 61. A verti stall carrying a. hand wheel 6 at its upper end is positioned upon the body portion and held in place by the pawl and ratchet arrruigri-nent the tall receiving the cables and an u when the latter are vxound thereon, the disks may be moved into a raised position and consequently out of engagement with the ground.

For purpose of more securely supporting the rear end of the rod in connection with the devicev we have provided a peculiar shaped brace rod 66 which has one end secured to a block 67 carried by the standard 49, while the other end ispivoted to a portionof'ihc axle shown by a sleeve 68 on the rear end oi the rod For purp=1 se of varying the speed of the drive and con equently facilitating the oporation ol the device, We ha ve fulcrumed, intern'iediate its ends, upon the cross-piece 2d, a lever pivotally connected at one end by a pin and slot arrangement 69 to the collar 70, loosely mounted upon the sleeve 31 be tween the gear and the pinion 31', and which lever and sleeve operate in conjunction with the pinion 31 and gear W ieel 30 so as to, at certain times, establish comi'nunic tion directly between the same and the gear and pinion on the shaft 33, however, they may be thrown out of enga gem out with each other at certain times when the machine is desired to be brought to a standstill. By the provision of the arrangement above referred to it will be appreciated as above set forth that the ellicienoy and opcrativeness of our invention has been greatly added to. For instance, if the mach ne is traveling at a certain rate of speed and the dirt clogs between the Wheels or they strike a stone or some hard structure. the operator can, upon the manipulation of the hand lever 70, dis-.

engage the pinion and gear Wheel on the shaft 93 from the pinion and gear Wheel on the sha t 33 through the medium of the ca bis 71, which operates on the friction roller 71 on one side of the bodv portion and has its respective ends connected to the ends of the hand lever 69 on the transverse bar 24. I t is obvious that the gears may be returned to their normal position by a spring (not shown) mounted in any suitable manner on the shaft The lever above referred to and designated by the numeral is pivoted as shown at 72 upon a segmental racl: 73, the latter being engaged by a pawl 74 carried upon the pivoted hand Wheel 75, the latter being of the usual type. By the provision of the pawland rachet arrangement inconnection with this device, it is apparent that the lever by our machine may be guided during its;

travel over the ground Which means is ins. 72

expensive to manufacture and easily de-, tached or attached to or from the machinewhen occasion :requi This guidingmech anism cons sts of a substantially vcrtica disposed stall 76 which has positioned there," on, and at its upper end a hand wheel 77. whereby the rotation of the stall may be ef--fi footed. The lower end o1 rethc'stan. as i'erred to has positioned thereon a Worm gear 78 which i'lormally meshes with a worn rv an? 79 which is "rrriod upon the longitudi nally extending rod S0 the latter having its forward end gournaled into t as supporting structure as shown at 81. Provided upon the rod 80 and preferably intermediate its s'r end. is a block which has connection at, 83 to a finger 85.- the latter being pivotally se cured to a transversely extending nieu'ibei" 85 as is clearly illustrated. The member 85 i mentioned extends transversely to the body portion of the device'ai'id is pivotally secured at its extremities as shown at 86 toa pair of links 87, the latter being in turnfast upon the pivoted sections 88 of the axle 12 as shown at 89.

readily apparent that as soon as the hafnd Wheel 77 is rotated, motion will be coniniunicated through the pair of Worm gears to the rod 80 and heels, and the Wheels of the ve hicle thereby moving the latter guide the machine during its travel over the ground. Vfhile We have illustrated the ordinary form of machine in the preferred form of; our invention, it is to be a v other forms of propelling means may be devised and provided such gas engines, electrio machines or .any suitable device. From the foregoing it is thought that the advantages and novel features of our invcn- 11'0- tion Will be readily comprehended.-

Ve desire it to be understood that we may make slight changes in the construction and in the arrangement and combination of the" several parts, provided, changes fall Within the scope of the subjoined claims.
