Application tiled JnnelO, IESS. (No model.)

'o all whom it may concern: l

Be it known that I, EZRA G. GODDARD, of East Saginaw, in the county of Saginaw and State of Michigan, have invented new and useful Improvements in Adjustable Rotary Sulky- Flows; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being' had to the accompanying drawings, which form a part of this specification.

The nature of this invention relates to certain new and useful improvements in that class of rotary plows wherein the caster-wheel or the wheel that guides the implement is actn ated by the tongue, and has the plows supported between said guide-wheel and the sulkywheels which support the drivers seat; and the novelty consists in the construction and arrangement of parts, as will be more fully hereinafter set forth, and specifically pointed out in the claims.

Figure 1 is a side elevation of my improved device as applied to a rotary plow provided with two disks. Fig. 2 is a plan view thereof. Fig. 3 is a detached perspective of the rear end of the frame. Fig. 4 is a perspective view of one of the subsidiary plow-disks.

In the accompanyingdrawings, A is the plowfratrie, which may be either of wood or iron, as desired, whilein thc drawings itis designed to be of wood. It consists ofthe base nwhich extends the whole length of the axle between the truck-wheels, and the beam b, which extends obliquely forward in one single piece, and the beam c, which is secured to the opposite end of the beam or base a, and is provided with extensions r1 c. The beam O and extensions d e are secured together at right angles to each other, and the whole is well secured together at the meeting and intersecting points, and forms a simple and rigid structure. Formed upon the forward end of the beam b is a cross-piece, c', provided with a series of holes for adjusting the evener, which is attached thereto by the usual clevis. The base It is secured at each end by bolts fi to the under side of the frame-pieces c c. A number of bolt-holes, 7s, near the bolts, form a means for securing the rod O in slightly-varying positions.

I) D are two rectangular 'frames sleeved upon the rod U, so as to be capable ot' a free swinging movement thereon. They may be very cheaply made, and very conveniently cousist of gas pipe and fittings firmly secured together. These two frames I) D are adapted to be laterally adjusted along the rod C in any desired position, and held there by collars provided with set-screws or pins passing through holes in said rod O.

E are two rotary disks, in each of which the outer or cutting rim consists of several sections which are removably secured by bolts with stinken heads to the cast portion thereof', which is preferably made in one piece comprising a hub, spokes, and rim, to which the several sections ofthe cutter are bolted. This construction greatly facilitates the regrinding of the cutting-edges when necessary, and is adopted in this plow also as a matter of necessity, as the means ordinarily employed for securing the rotary disks do not so well admit of their being readily removed. I do not, however, desire to confine myself to the construction ot' the disks above described, as it may be found convenient to construct such disks in one piece attached to proper spokes or rim or flange.

Two vertical standards, F F, are secured upon the frame A. They furnish a support to the shaft F', which is provided with a handle, G, which is placed within reach of the drivers seat H. A chain, I, connects each ofthe swinging frames D DA with the shaft F in such mauner that by winding or unwinding` the chains upon the shaft F the frames D D are raised or lowered. rlhe rod O termina-tes at one end in a loop or socket, l, through which the vertical part ofthe standard m of the castenwheel L passes, and is held in its vertical position thereby without interfering with its turning. rlhe weight of the forward end ot' the plow rests upon this caster-wheel, and by reason of an adjustable pin or collar upon the vertical standard under the socket Z the forward end of the frame can be adjusted to different heights in a manner well known in plows. To guide the easter-wheel iu the line of draft a IOO tongue, M, is adj ustably secured to the upper end of the standard, as shown, by means of which the team employed regulates the line of travel, and the easter-wheel is never liable to be turned out of its course by the plows crowding to the land.

N N are two plowsharcs or small disks of the same character already described, attached in proper position to cut the ridge left by the rotary disks at the bottom between the furrows. They are attached to vertical standards n n, which are secured in sockets o o on the under side of the swinging frames D D', as shown in dotted lines in Fig. 2.

In practice the raising and lowering of plow-disks is performed by the driver from his seat by simply turning the crank-handle so as to wind or unwind the chains I I, suitable catches or a notched segment being provided to keep the handle G in the desired position. The depth of furrow can be regulated within a certainlimit by theamount ofchain unwound from the shaft F. It also depends upon the height of the forward end of the frame, which is supported upon the caster-wheel, and, as before described, can be raised or lowered at will, and to obtain the best conditions for work the swinging frames D D should draw, for their ordinary working position, horizontally. N/Vhen two or more rotary disks are used it becomes quite necessary that the rod U should be in a horizontal plane. Thisv can 'be easily et'eoted by taking the bolt g out and turning the frame A upon the boltf as pivot until the desired result is obtained, when the frame A is again secured in its adjusted position by the bolt g.

the

To vary the angle of the plows with relation to the line of draft it is only necesary to change the bolts t' to other holes until the proper angle is obtained, and to make the most change of angle by the least movement of the ends,

Aboth for changing the angle ot' disk with the line of draft and the angle of disk with the ground for the shovel-scoop of the disk, the rods C may be in as many pieces as there are disk-frames, with a projection from the frame D between the disk-frames to fasten the ends to, as a short piece makes the most angle with the least movement ot' the ends.

If the ground in which the plowing is done should present no necessity for keeping the frames D Dl free. to swing, I can very easily introduce a device for looking the swinging frames in position while plowing.

In a rotary plow, the combination, with the frame A, consisting of the base a, beam b, and beam c, provided with extensions d e, ot' the shaft C and the separate U-shaped frames D D', swinging upon said shaft C, substantially as specified.

' 2.7111 a rotary plow, the combination, with the frame A, consisting of the base a, beam b, and beam c, having the extensions d e, of the shaft U and the swinging frames D D', the shaft being adjustably connected to the frame by bolts and holes, and the swinging frames constructed to slide on the shaft, as specified.
