ROTARY PLOW.

SPECIFICATION forming part of Letters Patent N 0. 463,047, dated November 10, 1891.

, Application filed August 27, 1891- Serial No. 403,887. (No model.)

plows in which a rotary disk-plow or cuttingwheel is mounted diagonally to the line of draft at the rear'of a suitable frame that is adj ustable on its axle to vary the distance between said plow and an adjacent staggered guidewheel by which the tendency to side draft, due -to the pressure of the soil against the plow, is

effectually prevented, while the soil thrown out by the plow is received on an unbroken or solid convex surface of the dished and staggered guide-wheel and discharged at the rear, so as not to retard the operation of the machine.

The invention consists in the construction, combination, and relative arrangement of parts in a rotary sulky-plow, as hereinafter more fully set forth.

In the annexed drawings illustrating the invention, Figure 1 is a perspective of a ro tary sulky plow embodying my improvements. Fig. 2 is a partial plan of the machine. Fig. 3 is a rear view of the machine. Fig. 4 is a vertical section through the lifting mechanism 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 adjustably attached to a straight axle 3, by means of clips 4 passed beneath the axle and through each hound, on the upper side of which they are secured by washers 5 and nuts 6, so that by loosening said nuts the frame of the machine can be adjusted laterally on the axle to give the required adjustment of the rotary plow toward or from the guidewhcel andthereby vary the widthof thefurrow, as here inafter explained. The hounds '2 may each be provided with a longitudinal 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 rearmost holes, as required, the frame of the machine may be adjusted rearward or forward,

as desired.

To the under side of the rear ends of the hounds or frame-pieces 2 are attached adjustable obliquely-arranged journal-boxes 8 by means of clips 9,,the upper screw-threaded ends of which are extended through holes or vertical perforations 10, formed in the hounds and secured by washers 11 and nuts 12 on the upper sides thereof. In the boxes 8 are supported rotary sleeves 13, through which is passed an obliquely-arranged bolt 14, on which, at the inner side of the right-hand hound, is mounted a dish-shaped rotary plow or cuttingwheel 15, with its concaved side turned outward and forward. On the bolt 14, adjacent to the convex side of the rotary plow 15, maybe placed an intermediate sleeve 16, and on one end of the said bolt is a nut rotary plow securely onto the bolt 14, which,

together with the sleeves 13 and 16, form an axle for said plow. The separate intermediate sleeve 16 may be dispensed with or made in one piece with the adjacent sleeve. It will be seen that the left-hand houndis of greater length and is extended somewhat in rear of the right-hand hound, and also that the boxes 8, attached to the rear ends of said hounds, are placed obliquely, so that the rotary dished plow 15 will occupy a position diagonal to the line of draft. By providing a number of suitably-arranged vertical perforations 10 in the rear ends of the hounds 2 the clips9 and obliquely-arranged boxes 8 can be so adjusted as to vary the diagonal position of the plow to secure a suitable width of out.

On one end of the axle 3 is loosely mounted a land-wheel 18, which may, if preferred, be made dishing, as shown, for the purpose of obtainin g strength and stability. To the other end of the axle 3 is securely bolted a vertical bracket 19, having on its inner side a horizon tal socket 20, 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 portion of the bracket 19 is in the form of a plate 22, which is engaged in vertical guides 23, that form a socket for said bracket 19 on the inner side of a casting or plate 24, the outerside of which is provided with a downwardlyuand outwardly inclined boss 25, having a fixed'spindle 26, on which is loosely mounted a staggered an'd solid-dished wheel 27, thetire or rim of which runs against the inner edge of the last-made furrow and serves as a guide for the rotary plow or'cutting-wheel in making the next adjacent furrow. .It will be observed that the concave side of the dished and staggered guide-wheel 27 is turned downward and outward, while its convex side is presented toward the concave side of the dished rotary plow 15, and it will be further observed that by making the said guide-wheel 27 solid, as shown-that is, without spokes or ledges, but with a perfectlysmooth and unbroken convex surface-the 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.

The upper segmental edge of the bracket plate 22 is formed with a rack 28 for engagement of a pawl 29 on a hand-lever 30, that is pivoted to said bracket and formed with a lower rearwardly and upwardly curved end,

- which is connected by a link 31 with the sock eted guide-plate or casting 245, on which the staggered and dished guide-wheel 27 is carried. It is obvious that by this construction and arrangement of parts the movement of the hand-lever 3O forward or backward will lower or raise the bracket-plate 22 in the guides 23 of the plate or casting 24, and thereby lower or raise the hounds 2 and attached rotary plow 15, as the case may be. to vary' the depth of the furrow to be out. By throwing the hand'lever back until the pawl 29 comes against a ledge or stop 32 on the inner side of the bracket-plate 22 the rotary plow will be raised entirely from the ground and remain inoperative while the machine is drawn from place to place.

The width of the furrows can be readily varied as required by adjusting the hounds 2 laterally on the axle 3, as already mentioned, it being only necessary to loosen the nuts 6 on the clips 4 in order to shift the position of the hounds so as to carry the attached rotary plow 15 toward the guide-wheel 27,if it is desired to make a narrow furrow, or from said wheel to make a wide furrow, and then tighten the nuts 6, as before, to secure the parts in proper relative position for accomplishing the desired character of work. As before mentioned, the width of thecut or furrow made by the rotary plow 15 can also be varied by increasing or diminishing the obliquity of the boxes 8, which is effected by removing the washers 11. and nuts 12 and changing the position of the clips 9 in the perforations 10 to holdtheboxes 8 in the required position. By

loosening the nuts 6 on the clips 4 and adj usting the hounds 2 forward or back, the pos1- tion of the rotary dished plow 15 will be changed to bring it into more or less direct action with relation to the adjacent dished and solid staggered guide-wheel. By arranging this guide-wheel 27 in proximity to the rotary plow or cutting-wheel 15 the tendency to side draft under the pressure exerted against the rotary plow will be entirely obvlated 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 surface presented toward the plow, so that the soil thrown onto said wheel will pass off freely and rapidly to the rear and not hinder the working of the machine; tary plow and staggered guide-wheel having a solid convex surface also permits dispensing with a colter or rudder in rear of the plow, as frequently required in other forms of construction.

What I claim as my invention is- 1. In a sulky-plow, the combination, with a rotary plow or cutting-wheel and its supporting-frame, of an axle having a land-wheel at one end and a staggered dished guidewheel mounted at the other end of said axle and having a solid and unbroken convex sur- This relative arrangement of roface in proximity to said plow to receive the soil thrown onto it by the plow and discharge it at the rear, substantially as described.

2. The combination, with a diagonally-arranged rotary plow or cutting-wheel and its supporting-frame, of an axle on which said frame is laterally adjustable, a land-wheel at one end of said axle, and a staggered and dished guide-wheel mounted at the other end of the axle in proximity to the rotary plow and having a solid and unbroken convex surface presented toward said plow, substantially as described.

3. The combination, with an adjustable diagonally-arranged rotary plow or cutting.

wheel and an adjustable frame on which said plow is mounted, of a solid and dished guidewheel mounted in a staggered position adjacent to and outside the plow slightly in advance thereof and having a solid convex surface presented toward thelplow to receive the soil and discharge it at the rear, substantially as described.
