SPECIFICATION. forming part of Letters Patent No. 398,266, dated February 19, 1889.

Application filed August 7, 1888. Serial No. 282,139. (N0 model.)

To aZZ whom it may concern.-

Be it known that I, IRA M. L1NDERMAN,a citizen of the United States, residing at Elmira, in the county of Chemung and State of New York, have invented a new and useful Improvement in Sulky-Plows, of which the following is a specification.

My invention relates to an improvement in sulky-plows; and it consists in the peculiar construction and combination of devices that will be more fully set forth hereinafter and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a top plan view of a sulky-plow embodying my improvements. Fig. 2 is a side elevation of the same. .Fig. 3 is a vertical longitudinal sectional view of the same, taken on the line a" w of Fig. 1. Fig. 4 is arear elevation. Figs. 5 and 6 are detail views.

A represents a U-shaped frame, which comprises a front bar, 13, and rearwardly-extending arms 0. The rear ends of the said arms are turned inward at right angles to form brackets D, which are bolted to transverse plates E. The latter are provided on their rear sides with bearings F, in which are journaled a pair of short axles, G, that project outward in opposite directions.

H represents a vertical rectangular frame, whichis secured to the plates E and has a pair of vertical side bars, 1, and a central vertical bar, K. From the said bars I and K, at a suitable distance from their lower ends and arranged in the same horizontal plane, project rearwardly-extending brackets L, which are bolted to the said bars, as shown.

Arranged parallel with the front bar, B, is a crossbar, M, which has its end turned rearward at right angles, as at N, and bolted to the arms 0 of the frame A.

0 represents the draft tongue or pull, which has its heel arranged on the centers of the bars B and M and secured thereto by means of clip-bolts P.

R represents two pairs of arms, which are connected at their rear ends by transverse rods S, and the front ends of the said arms are pivoted to the brackets L by means of .bolts T, whereby the said arms are adapted to be moved upward and downward.

U represents a pair of frames, each of which comprises a pair of horizontal plates, V, which are rectangular in shape, are arranged one above the other, and are connected at their rear corners by vertical bolts washers or blocks X being secured on the said bolts to space the plates apart. The crossbars S, which connect the rear ends of the pairs of arms R, pass through the frames U between the plates V, and thereby the said frames are adapted to move longitudinally on the said rods. Formed at the rear end of each upper plate V is a sector-shaped plate, Y, which is arranged in a vertical plane and is provided with notches Z in its periphery.

A represents a pair of bars or plow-beams, which have their front ends curved inward and caused to lie in proximity to each other. The rear portions of the said beams or rods pass longitudinally under the frames U, and are rigidly secured thereto by means of clipbolts B. The said rods or beams project rearward from the frames, and on the same are mounted plates C, which are provided with bearings D, engaged by the rods or beams, the said plates being thereby adapted to be turned on the said rods or beams, as will be readily understood. The upper ends of standards E are secured to the said plates, and to the lower ends of the said standards are secured plows F, of suitable construction, which are adapted to turn furrows outward in opposite directions. Rigidly secured to each plate 0 is a vertical hand-lever, G. The said hand-levers bear against the rear sides of the sector-plates Y and are provided with spring actuated locking-bolts H, which are adapted to engage the notches Z, so as to secure the levers to the sector-plates at any desired adjustment. By means of these levers it will be understood that the plows may be arranged either in a vertical position or any desired lateral inclination with their soles at any desired distance apart, so as to prevent the plows from becoming choked when operating in turf or ground that is obstructed with weeds.

Right and left hand plows F are illustrated in the drawings, adapted to throw furrows in opposite directions, and when thus equipped the invention is used as a sidehill or reverse plow, one plow being at work while the other IOO is idle. I propose, however, to in some instances employ plows which are adapted to throw furrows in the same direction, and thereby adapt the invention for use as a gangplow, and I do not therefore desire to limit myself in this particular.

I will now proceed to describe my improved clevis.

1 represents a pair of vertical arms, which are provided in their lower portions with a series of transverse openings, K, arranged one above the other, and have eyes L at their upper ends, through which the front ends of the plow beams or bars A extend. The said plow beams or bars have heads or swages h formed at their front ends to prevent them from slipping rearward through the eyes, and the arms I are connected together and pivoted by means of the transverse bolts N, which pass through one pair of theopenings K at any desired distance from the lower ends of the arms.

0 represents. a draft-hook, which has its rear end forked, bearing against the outer side of the arms I, and pivoted on the bolt N, and to this hook is connected the usual doubletree, P. By means of the pivotal bolt N the arms I are rendered movable independently of each other, and the beams or rods A being secured to the longitudinallymovable frames U, and having their f ron t ends guided in the eyes L of arms I, the plows are adapted to work back and forth in a longitudinal direction independently of each other, so that the greatest draft will be exerted on the plow which happens to be deepest in the soil.

R representsa pair of levers, which are fulcrumed near their centers on brackets S, that project from the outer sides of the frame H near the upper end thereof. The rear ends of the said levers are connected to the frames U'by meansof links T, and the front ends of the said lever are pivoted to depending links U.

V represent-s a pair of rock-shafts, which are-journaled inbearings W, that are bolted to the cross-bar M, and are provided at their inner ends with arms X, the rear ends of which are pivotally bolted to the lower ends of the links U.

Y represents a pair of hand-levers, which are secured to the outer ends of the rock-shaft V and play on the outersides of sector-plates W hich are secured to the front corners of the frame A and are provided with notches A The levers Y have the usual springactuated locking-bolts B which are adapted to engage the notches A and to lock the levers Y in any desired position.

It will be observed that when the levers are moved forward the rock'shafts are partly rotated, so as to elevate the rear end of the arms X and cause the links Uto raise the front end of the levers R and the links T, connected to the lower ends of said levers, to

lower the rear end of the arms R and the are wheels 0 which serve to support the frame and impart rotary motion to the shafts G, and also secured to the said shafts and retating therewith are ratehet-whecls D represents a pair of links, which depend from and are pivot-ed to the levers R at a suitable distance in advance of the fulcrums thereof, and said links are provided on their rear side with ratchet-teeth F which are adapted to be engaged by the ratchet-wheels. Gr represents a pair of foot-levers, which are curved, as shown in Figs. 2, 3, and 5, are fulcrumed to the arms 0 of the frame by means of bolts H and have their lower ends connected to the lower ends of the links E by means of rods 1' Pivoted on each of the see tor-plates Z is a trip-lever, K the longer end of which bears normally under the lockingbolt B of the hand-lever Y when the latter is secured at the forward limit of its movement. A lever, L is also pivoted to each of the sector-plates Z, is provided with the depending studs M adapted to engage the proximate rear end of its companion trip-lever K and the rear end of the said'lever L is normally arranged under the notch A near the rear end of the sector-plate. The said levers L have their front ends connect.-

' ed to the levers G by means of rods N 0 represents a pair of coiled retractile springs, which have their front ends secured to the front corners of frame A and have their rear ends connected to the lower ends of the foot-levers G2 by means of rods P, the function of the said springs being to normally retain the foot-levers and the leversK and L in the positions hereinbefore stated, and illustrated in Fig. 5, when the hand-lever is moved forward. From the upper end of each foot-lever projects an inwardly-extending rung or arm, R, which is readily pressed against by the foot of the driver.

The operation of this part of my invention. is as follows: When the lever Y is secured at the forward end of its stroke, and the foot-lever is disengaged by the foot of the driver, the spring 0' draws forward on the rear of the foot-lever, and consequently causes the rod I to move the lower end of the ratchet or rack link forward, so as to disengage the latter from its companion ratchetwheel, and the upper end of the foot-lever draws rearward on the rod N and consequently raises the front end of the lever L The link-levers being disengaged from the ratchet-wheels, and the plows being lowered, are caused to operate in the ground as the machine is drawn forward, and the lockingbolts B being in engagement with the notches at the front end of the sector-plate Z the rock-shafts V are locked, so that the links U T and the levers R are caused to maintain the frames U against vertical movement, and thereby prevent the plows from rising from the furrows. I11 order to elevate the plows, the operator presses with his feet against the foot-levers G so as to thrust the upper ends of the same forward. This movement of the foot-levers causes the rods N to lower the front ends of the levers L so that the latter depress the rear ends of the trip-levers K and cause the front ends of said trip-levers to release the locking-bolts B from the front notches of the sector-plates Z. At the same time the rearwardly-moving lower ends of the foot-levers thrust the rods I rearward against the tension of the springs O and cause the teeth of the links E to become engaged with the teeth of the wheels D and the said wheels in revolving with the forward motion of the machine draw downward on the said links, and consequently draw downward on the front ends of the levers R, so as to raise the frames U by means of the links T and arms R, and consequently elevate the plows. As the front ends of the levers R descend, the links I move the arms X downward, and thereby partly rotate the rock-shafts V, so as to cause the latter to move the hand-levers Y to the position indicated in Figs. 2 and 3, when their locking-bolts become engaged with the rear notches, A and with the rear ends of the levers L thus serving to lock the hand-levers in this position, and consequently prevent the plows from descending. As soon as this is accomplished the operator removes his feet from the levers G and the springs O instantly draw upon said levers and the rods 1 so as to disconnect the toothed links E from the wheels 1)".

From the foregoing it will be understood that the plows may be automatically raised or lowered without any exertion on the part of the driver other than to operate the levers G and hence no strength is required on the part of the driver, and the plow may be very readily operated even by small boys.

A seat, S is supported above the center of the vertical frame H bymeans of a spring, T

U represents a pair of brace-rods, which connect the vertical corners of the frame H to the front bar, B, of the main frame.

Having thus described my invention, I claim- 1.
