RIDING-PLOW.

SPECIFICATION forming part of Letters Patent N 0. 704,274, dated July 8, 1902.

Application filed July 15,1901. Serial No. 68,403. (Model) T aZZ whom it int/,3 concern.-

Be it known that we, CHARLES S. RUEF and CLARENCE L. TOMLINSON, residing at Dixon, Lee county, Illinois, have invented certain new and useful Improvements in Riding- Plows, of which the following is a specification.

Our invention relates to improvements in what are commonly known as riding-plows; and the object thereof is to provide novel and efficient means for both raising and lowering the plow proper by means of the feet, thus leaving the hands of the driver free for driving or for other purposes.

A second feature of our invention pertains to a hand lifting-lever cooperating with the plow proper for the purpose of raising or lowering the same and arranged to be manipulated independently of or in conjunction with the said foot-actuated mechanism.

The advantageous features of construction and operation of our improvements will be readily apparent from the description hereinafter given.

In the drawings, Figure l is an elevation of a riding-plow embodying our invention and showing the plow proper in substantially lowered position; Fig. 2, a plan view of those parts of the riding-plow in which our invention resides; Fig. 3, an elevation of the footactuated mechanism or devices for raising and lowering the plow and illustrating the rela-* tive position of the various parts when the plow is lowered, this figure being on a somewhat larger scale as compared with Fig. 1; Fig. 1, a view similar to Fig. 3, except that the various parts are shown with the plow in raised position; Fig. 5, a section on line A B of Fig. 2. Fig. is a sectional elevation on the line 5 of Fig. 2, showing particularly the connections 21, 22, and 23; Fig. 6, an elevation of the hand lifting device with the lever thereof in disengaged position; Fig. 7, an elevation of the hand lifting device, but with the plow-beam and bracket of said device in section; and Fig. 8, a section on the line C D' of Fig. 6, except that the lever has been put into engagement with the notched arm.

The riding-plow proper may be of suitable construction, and, as herein shown, the same comprises a main frame 1, the two furrowwheels 2 and 3, the land-wheel 4, and a plow 5 and its beam 6, supported in the main frame in the usual and well-known Way. The landwheel is mounted at the lower end of an axle '7, which has a substantially vertical portion and a substantially horizontal portion. A suitable leveling-lever 8 is pivoted on the horizontal portion of this axle, and a yielding connection between it and such axle is provided in the coiled spring 9, surrounding the curved rod 10, which is fastened at one end to the arm 11, secured to the axle and which is arranged to pass loosely through the said leveling-lever, as will be readily apparent from an inspection of Fig. 1. The horizontal portion of the axle extends longitudinally through a sleeve 12 and-carries at its inner end toward the plow-beam an arm 13, to which the spring 14 is connected, against the tension of which spring the adjustments of the land-wheel are obtained. This sleeve is arranged to rock in the plow-frame, and to this end the main frame has an auxiliary frame composed of the bent strip or bar 15, extending laterallyin a direction toward the landwheel. Secured to these frames are bearing-brackets 16 and 17, having bearings by which the sleeve is received and in which it is adapted to rock or partially rotate. The sleeve has a sector 18, with which the leveling-lever is adapted to cooperate in the wellknown way.

The bearing-bracket 17, which is attached to the ,main frame, is provided at a point above such frame with a journal or hearing 19 to receive the short shaft 20. Upon one end of the shaft is secured a crank-arm. 21, which is connected by means of the bent link or arm 22 to an arm 23, forming a part of or secured to the sleeve 12. The other end of the shaft carries a lever 21, which will for convenience be termed the lowering-lever, because it is more particularly concerned in the lowering operation of the plow. In the present instance this lowering-lever is secured at its lower end to the shaft 20, while its upper end is forked, the fork or arm 25 of which has a footpiece 26. The other fork or arm 27 is pivotally connected to a link 28,

whose lower end is in turn pivotally connected to a bracket 29, which is fastened to the plow-beam 6, as clearly illustrated in Fig. 2. The forward and backward movements of the lowering lever are communicated through the various parts above described to the plow-beam bracket, so as to raise and lower the latter in a manner which will be hereinafter more particularly described when the raising and lowering operations are explained.

A lever, which will be termed the raisinglever, is pivoted or loosely mounted intermediate of its length on the shaft 20, its upper or longer arm 30 carrying at its outer end a pivoted footpiece or stirrup 31. The shorter arm 32 of this raising-lever is pivoted upon a connecting bar or link 33, whose forward end is connected to the plow-beam bracket 29 in the same manner and upon the same pin or rod 34 as the link 28. As clearly shown in Fig. at, the arm 32 is pivoted to the link 33 intermediate of the length of the latter, thereby leaving a short arm 35 projecting rearwardly. The lower edge of the arm 32 has a projecting lug 36, provided with a set or adjusting screw 37. This lug forms an abutment or stop for the arm 35 in the lowering operation. The set-screw is adapted to regulate the limit of movement of such arm 35 for a purpose hereinafter explained. The lever 24 is also provided with a stop 38, against which the link 28 will strike, as shown in Fig. 4.

Starting with the parts in the position shown in Fig. 3, which is the lowered position, the operation of raising the plow will now be explained. In the lowered position the upper end of the raising-lover and its stirrup is rearward toward the driver, while thelowering-leveris positioned forward. The driver having his feet on the respective levers now forces or shifts the raising-lever forward and permits the lowering-lever to move backward, whereupon in case it is desired to lift the plow wholly from the ground the parts assume the position shown in Fig. 4, the link 28 coming to rest against the stop 38 on the lever 24:. The raising-lever has thus carried the plow-beam bracket, and consequently the plow, upwardly, and at the same time the arm 21 will move the link 22 until the pivotal point at the rear end of such link is below the pivotal point at the forward end thereof, whereby said parts will be locked in position, but not against the exercise of positive force by the driver. The lowering-lever is now in its rearward position with the link 28 in substantially vertical position and limited in its movement by the stop 33. \Vhether or not the driver keeps his feet on the levers the parts will remain in said raised position by virtue of the particular construction and operation of the parts 21, 22, and 23, which thus constitute locking mechanism. Now when it is desired to lower the plow the loweringlever is forced forward and the raising-lever permitted to move backward, whereupon the plow-beam bracket, and consequently the plow, will be lowered. The link 33 assumes a substantially vertical position with its arm 35 carried beyond the center and abutting against the stop or set-screw 37, so that the parts are locked in lowered position, but not against positive force due either to the driver or to some unusual obstruction. The strength of the'lockthat is, the amount of force necessary to unlock the mechanismmay be varied by the set-screw, which permits a passing of the center to a more or less degree accordingly as the set-screw is adjusted in or out. In this way the amount of resistance offered by the plow to any obstruction or even to the driver may be varied at will. By reason of the pivoting of the stirrup 31 on the outer or upper end of the raising-lever means are provided for the proper actuation of such lever by the foot of the operator. This stirrup is more particularly useful on the backward stroke of the raising-lever,when

a substantial downward thrust on the stirrup.

will bring the raising-lever to its limit of stroke and cause it to be locked in such position. Were it not for the provision of this stirrup it would be necessary for the driver to push directly rearwardly on the footpiece, which would be an inconvenient and difficult operation. \Vhile only one of the levers is provided with a pivoted stirrup, because it is more particularly useful in connection therewith, yet it is obvious that such a stirrup may be applied to the other lever as well. In the raising and lowering operations the sleeve 12 has a slight rocking or oscillatory movement, which is communicated through the sector 18 to the land-wheel axle and to the land-wheel, so that the land-wheel axle partakes slightly of said movement, with the resuit that the machine is leveled to some degree simultaneously with the raising and lowering of the plow. The hand-lever S is, however, a leveling-lever, and as this name implies and as a matter of fact its function is solely to level the machine and not to raise or lower the plow, which latter functions are performed either by the foot-actuated devices or by the hand-lever 46, or by both. The hand-lever 8, therefore, has no effect upon the raising and lowering of the plow with respect to the frame.

While the various parts hereinbel'ore described in detail serve to accomplish the purposes and objects hereinbefore made apparent, yet it is obvious that mechanical changes may be made in the shape and arrangement of the various parts without departing from the spirit and scope of our invention and claims.

In addition to the foot-actuated raising and lowering mechanism hereinbefore described the machine may be provided with an independent hand-operating raising and lowering device which is adapted to be operated independently of or in conjunction with said mechanism. In the present instance such lever device comprises a bracket 39, secured in any suitable manner to the sulky-frame and having bearings for a transverse shaft $0, on one of whose ends is secured a forwardly-projecting arm 41,pivotally connected at its outer end with a lifting-link 42, which projects downwardly and is pivotally connected at its lower end to a bracket 43, secured to the plow-beam. To the other end of the shaft 4.0 is secured an arm or projection 44, provided with a vertical notch 45. Loosely pivoted or mounted upon the shaft 40 is the hand lifting-leverfi, provided with a spring-pressed plunger 47 and the thumblatch 48, connected thereto. The bracket 39 is provided with projections or stops 40 and 50, on which this lifting-lever may rest or be supported when it is in the position of dis engagement from the parts with which it is associated at the will of the driver. Then this lifting-lever is in the position shown in the drawingsthat is, in its position of disengagementthe foot-actuated raising and lowering mechanism operates, as before, for the purpose of raising and lowering the plow. However, when it is desired to work the hand lifting-lever independently of or in conjunction with said foot-actuated mechanism the plunger 47 is caused to engage in notch 45, whereupon by shifting the hand lifting-lever forwardly or backwardly the plow will be raised or lowered by reason of the connections between the shaft 40 and the plow-beam, as hereinbefore stated. Itis obvious that the hand lifting-lever is adapted to do the entire work of raising and lowering the plow and also that'it may be used to assist the footactuated mechanism as may be desired or found necessary by the driver.

Referring to the foot-actuated devices hereinbefore described, complete strokes of the levers operate to raise or lower the plow to its full extent; but it is evident that the driver may by partial strokes raise or lower the plow to any predetermined level and maintain it in such position by his feet.
