.To all 'whom .it may concern.

Be it known that I, MILTON TAYLOR HAN- State of Louisiana, have invented certain new and useful Improvements in Rotary Plow's, of which the following is a specification.

This invention relates to that class of sulkyplows in which a rotary plowing-disk .or cutting-wheel is modnted diagonally to the line of draft on a suitable frame supported by carrying-wheels and an axle.

- It consists in such an arrangement of the several parts that the tendency tosidedraft due to the pressure ofthe soil againstthe plow is efiectually counteracted.

In my preferred construction the soil thrown out by the plow is received on an unbroken or solid convex surface of a dished or staggered guide-wheel and discharged at the rear, so as not to retard the operation of the machine. v

Said invention will first be fully described,

.- and then pointed out in the claims.

In the annexed drawings, illustrating the invention, Figure 1 is a perspective of a retary sulky-plow embodying myimprovements. Fig. 2 is a partial plan of the machine. Fig.

. 3 is a rear view of the machine. Fig. at is a vertical section through the lifting meehan ism of the rotary plow, and Fig. 5 is a section through the rotary plow and its axle.

Referring to the drawings, the numeral 1 designates a draft-tongue, which is firmly secured to the forward ends of hounds 2, that constitute the frame of the machine. About midway their length the hounds 2 are adthereby vary the width of the furrow, as hereinafter: explained. The hounds 2 may each be provided with a longitudi nal series of holes or vertical perforations 7 for passage of the screw-threaded ends of the clips 4, so that by inserting said clips in the foremost or rear- 'lIlQSt holes, as required, the frame of the ma-' chine may be adjusted rearward or forward, asdesired. j I

To the under side of the rear ,ends of the hounds or frame-pieces, 2 are attached adj ustable obliquely-arranged journal-bpxes S by means of clips 9, theupper' serew threaded ends of which are extended through holes or vertical perforations 10, formed in the hounds andsecured by washers 11 and nuts 12 on the upper sides thereofl In the boxes 8 are supported rotary sleeves l3,'through which is 15, may be placed an intermediatesleeve 1G,

and on one end of the said bolt is a nut 17:, which may be turned up tightly to draw the sleeves together, and thereby clamp the retary plow securely onto the bolt ll, which, together with the sleeves 13 and 16, form an axle for said plow. The separate intermedipassed an-obliquely-arranged bolt ll, on

ate sleeve 16 may be dispensed with or made in one piece with'the adjacent sleeve. It will be seen that the left-hand bound is of greater length and is extended somewhat in the rear of the right-hand bound, and also that the boxes 8, attached to the rear ends of said hounds, are placed obliquely, so that the retary dished plow 15 will occupy a position diagonal to the line of draft. By providinga n umber of suitably-arranged vertical perfcrations 10 in the rear ends of the hounds 2 the clips 9 and obliquely-arranged boxes 8 can be so adjusted as to vary the diagonal position of the plow to secure a suitable width of en t.

' On one end of the axle'ii is loosely mounted a land wheel 1S,',w;hich may, if preferred, be made dishing, as shown, for the purpose of obtaining strength and stability. To the other end or the axle 3 is securely bolted a vertical bracket 19,- having on its inner side a horizontal socket :30, in which the end of said axle is received. The lower end of this bracket 19 is connected by a brace rod or bar 21 with the forward end of the adjacent hound, thereby securing the said bracket against the effects of strain. The outermost guide-wheel 27 is turned downward and out- I shown-that is, without spokes or ledges, but

portion of the bracket 19 is in the form of a plate 22, whichis engaged in vertical guides 23, that form-a socket .for said bracket 19 on the inner side of a casti-ng'or plate '24, the outer side of which is provided with a down-' wardly'and-ont-wardly inclined boss 25, having a fixe'dspindle 26, on which is loosely mounted a staggered and preferably solid and dished wheel 27, the tire or rim of which has an approximately sharp 'edge, which runs against the inner edge of thelast-made furrow and serves as a guide for the rotary plow Orcutting-Wheel 15 in making the next adja cent furrow. It will be observed that the concave side of the dished and staggered ward, while its convex side is presentedtoward theconcave side of the dished rotary plow 15, and it will be further observed that.

by making the said guide-wheel 27 solid, as

with a perfectly smooth and unbroken convex operative surfacethe soil thrown -thereon by the rotary plow will readily pass off at the rear of the machine without any liability of being carried forward to clog the operation of the wheel. One of the main features of my invention is the relative arrangementof thls g uide-whee.l and the plowing-disk or cutting-wheel. As has already been stated,

line of draft and said guide-wheel is staggered or inclined outwardly. By refernce to the drawings it willybe observed that the 3S axis of the plowing disk or disks issnbstantially coincident with a line passing therefrom across thefurrow toabove or nearthe bearing on which theguide-wheel turns, and

thus the two points of strain, are nearly or quite oppos te to each other, and the resistance provided by the guide-wheel thiis coun' teracts the strain of the plowing-disk occasioned by turning the furrow nearly or quite in direct line. This being so, what is known as side draft is practically eliminated from the operation of my maehine, and the animals which draw the machine have little else te do except to furnish the necessary power to draw it forward, the labor of keeping it in line being inappreciable. 1

The upper segmental edge of. the bracket- ,plate 22 is formed with a rack 28 for engagement of a pawl29 on ahand-lever 30, that is.

{pivoted to said bracket andformed with a lower rearwardlyand upwardly curved end,

which is connected bya link 31 with thesocketedgifide-plate -or casting 24,0!1' which the staggered and dished guide-wheel 27 is carried. It is obvious that by this construction 66 and arrangement of parts the movement of the hand-lever 30 forward or backward will loweror raise'thebrackct-plate22 in the guides 23 of the plate or casting 24, and thereby lower or raise the bounds 2 and attached, rotary plow 15, as the case maybe, to vary the depth of the furrow to be cut.1 'By throwing the landlever back until the pawl 29 comes against alcdge or stop on the innerside inoperativewhile the machine is drawn from place to place.

ried as required by adjusting the hounds 2 laterally on the axle 3, as already mentioned, it being only-necessary to loosen the nuts 6 0n the clips 4 in order to shift the position of thehonnds, so as to carry the'att'ached-rotary sired'to make a narrov "ir'row, or from said tighten the nuts 6, as before, to secure the parts in proper relative position foraccomplishing the desired character of work. As before mentioned the width of the cut or forrow made by the rotaryplow 15 can also be varied by increasing or diminishing the obliquity of the boxes 8, which is effected by reing the posit-ion. of the clips 9 in the perforations 10 to hold the boxes 8 in the required position. By" loosening the nuts 6 on the clips 1 and adjusting the-hounds 2 forward plow '15 will be changed to bring it into more or less direct action with relation to the adjacent staggered guide-wheel. By arranging plow or cutting-wheel 15 in the relation above specified the tendency to side draft under the pressure exerted againstthe rotary plow will be entirely obviated and the machine will be caused to move properly and lay the furrows evenly in the desired direction. The operation of the plow is also greatly facilitated by making the staggered guide-wheel 27 in dishing form and with a solid unbroken convex surfacepresent'ed toward the plow, so that the soil thrown onto said wheel will pass off freely and rapidly to the rear and nothinder the working of the machine. This relative arrangement of rotary plow and staggered guide-wheel having a solid convex surface also permits dispensing with acolter or rudder in rear of .the' plow, as frequentlyre: quired in other forms of construction.
