.To all whom t Netty concern:

Beit known that I, SAMUEL H. TINsMAN, a citizen of the United States, residing at Davvenport, in the county of Scott, State of Iowa, have invented a certain new and useful Improvement in Sulky-Plows, of which the following is a specification. Y Y

My invention relates to wheeled plows in general, but more particularly to plows of this character havinga number of supportingwheels, the arrangement being such that the wheels and the plow can be adjusted or shifted relatively for the purpose of eitherfraising or lowering 'the plow, and especially to a plow of this description constructed withont'any special framework and in which the plow is characterized by what is known as a high lift.

Generally stated, the object of my invention is to provide a serviceable and highly efficient construction of wheeled plow.

A special object of my invention is toprovide a frameless wheeled plow-having all of the essential elements and desirable characteristics of a frame-plow, but dispensing with all of the objectionable and undesirable features which usually characterize the latter.

It is also an object of my invention to provide a construction tending to reduce the weight and number of parts to a minimum, but at the same time insuring'the requisite strength and rigidity.

A further object of my invention is to providea construction and arrangement whereby all necessary or desired adjustments or manipulations of the machinemay be accomplished readily and with the least effort.

Another object is to provide an improved and highly efficient and serviceable const-ruction and arrangement whereby all of the supporting-wheels can be simultaneously controlled by a single hand-lever, so as to permit the plow to be bodily raised and lowered without the necessity of adjusting or manipulating more than one lever.

Another object is to provide a relative arrangement Of the parts whereby the throw of the operating-lever beyond a certain point will confine the adjustment or relative movement to the forward supporting-wheels.

In addition to these it is also a special object wheels.

A' 'further object is to provide an improved arrangement whereby the tongue may be employed for holding the caster-wheel spindle against turning while the machine is running straight ahead, but which will permitA the tongue to automatically release such casterwheel when it is desired to alter the direction of travel or to turn the machine around.

Another feature of special improvement consists in connecting the caster-wheel with the tongue in such manner that the plow can be raised from the ground without throwing the caster-wheel out of alinement.

An improved arrangement for permitting the furrow-side wheel to be ad j usted laterally ,is also provided, and in addition to this a spring is arranged to assist in raising the plow from the ground.

lt is also an object of my invention to provide certain details and features of improvement tending to increase the general efficiency and to'render a plow of this character more serviceable and satisfactory in use.

To the foregoing and other useful ends my invention consists in matters hereinafter set forth and claimed.

In the accompanying drawings, Figure l is a perspective of a wheeled plow embodying the principles of myinvention. Fig. 2 is a side elevation of the plow shown in Fig. l. Fig. 3 is a plan of the plow shown in Fig. 2. Fig. 4t is a detail sectional view showing the construction of the coupling or device for controlling the land-side wheel independently of the other wheel. Fig. 5 isa sectional view showing the devices for permitting a lateral adjustment of the furrow-side wheel relatively to the balance of the machine. Fig. 6 is a view similar to Fig. 2, but showing the position of the various parts when the plow is raised or lifted from the ground. Fig. '7 illustrates the extreme downward adjustment of the plow into the ground.

As thus illustrated the plow is of the frameless and high-lift type, it being observed that IOC the plow-beam constitutes the only frame or body structure with which the machine is provided and that the relative movement between the plow and the supporting-wheels is such that the plow is given a high liftthat is to say, the plow is raised or lifted from the ground to more than the usual extent. The wheeled plow thus constructed and operated comprises, preferably, a suitable plow A, a plow-beam B, and a number of supportingwheels C, D, and E. The plow and beam are supported by these vehicle-wheels in such manner that the plow can be lowered into a working position, as shown in Fig. 2, or raised from the ground, as shown in Fig. 6. As stated, the plow-beam is the only body strncture with which the machine is provided, and the said wheels are therefore preferably provided w-ith shifting connections secured directly to the said plow-beam. For example, the land-side wheel D is preferably mounted on a crank-axle F, which is arranged to turn or rotate in a bearingf,which is bolted orotherwise suitably secured to the said plow-beam. This crank-shaft is preferably made in two sections, the innersectionf being arranged to turn in said bearing, while the outer sectionfzis formed with the crank-arm and spindle upon which the wheel D is mounted. The two sections f and]c2 are preferably coupled together by a coupling or bracket f3 and the segmental rack device f4. The axle-section f is adapted to turn or rotate in the said coupling or bracket f3, while the section f2 is squared at its end and clamped within the split portion f5 of said coupling or bracket. The segmental rack device f4is also preferably split at its hub portion and clamped upon the axle-section f. The hand-leverfG is preferably rigid with the said coupling or bracket f3 and is preferably provided with a hand-operated locking-bolt l. This locking-bolt is adapted'to engage the teeth of said rack, and with this arrangement the said lever, the coupling or bracket, the outer axle-section f2, and the wheel D are all rigidly connected and adapted to move or turn together. It will be seen, therefore, that whenthe locking-bolt l engages the rack f4 the two sections of the crank-axle are locked together, and the entire axle carrying the land-side wheel D can then rotate in its bearingf. Should it be desired, however, to control or adjust the land-side wheel independently' of the other wheels, the locking-bolt l can be withdrawn from engagement with the rack f4, and the operating-lever f6 can then be manipulated to rock or rotate the coupling or bracket f3 upon the axle-section f', so as t0 cause a relative shift between the landside wheel D and the balance of the machine.

With respect to the simultaneous adjustment or control of the three supportingwheels-that is to say, with respect to the bodily raising or lowering of the plow-the axle-section j" is preferably provided at its end with a hand-lever f7, whereby the entire crank-axle can be rocked or rotated in its bearing f. As a means for locking this crankaxle against rotation relatively to the plowbeam, the latter can be provided with a segmental rack f3, adapted and arranged to be engaged by a locking-boltf on the lever f7. This locking-bolt, like the one previously described, can be operated by a small latchlever arranged at the upper end of the lever, substantially as shown in the drawings. In order that this lever f7 may be rigidly secured to the crank-axle, the latter is preferably provided at its end with a squared por-Y tion, as shown in Figs. 1, 2, and 6, and the lower end portion of this lever can be split and provided with a clamping-bolt for clamping it upon said squared portion of the crankaxle. Vith this arrangement it will be s een that two adjusting-levers are provided, one rigid with the crank-axle, while the other is capable of movement independently of the main portion of such axle, whereby the entire crank-axle can be rotated or whereby only the end or crank-arm portion of such axle may be caused to move or swing relatively to the main section f'. As stated, the lever]c7 is preferably connected and arranged for simultaneously controlling all of the supporting-wheels, so as to permit the plow to be raised and Vlowered bodily without the necessity ofmanipulating more than one lever. To such end the furrow-side wheel Gis preferably mounted upon the outturnedlowerend portion of avertically-disposed standard c,arranged in a sleeve or bearing c. This sleeve or bearing is preferably provided with a portion which extends inwardly and which is bolted to the bracket c2, the latter being in turn bolted or otherwise secured to the plow-beam. It will be observed that the bolts for securing this bracket c2 and the casting providing the sleeve or bearing c' are preferably arranged for adjustment in slots c3, whereby the line of travel of the furrow-side wheel can be changed at will. The sleeve or bearing c' is adapted to slide up and down upon the standard c, and it will also be observed that the furrow-side wheel thus mounted is adapted to turn or swing with the tongue G. The rock-shaft H is preferably provided with a pair of crankarms 7L and h', and it is preferably mounted in bearings h2 and h3. As will be observed, this rock-shaft is preferably squared for its full length, and while the crank-arm h may be integral with the rock-shaft the crankarm h is preferably made separate and yadapted to be clamped in place. With respect to the lateral adjustment of the furrow-side wheel and as the said rock-shaft is preferably squared for its full length the bearings for the same are preferably provided with bushings h4 and h5, which are cylindric and turn with the shaft. The bracket c2 is preferably provided with a lug c, which prevents the crank-arm h' from shifting sidewise when the parts are loosened and the furrow-side wheel adjusted laterally. A link fw is preferably provided and arranged to serve as a medium of connection between the lever]e7 and the IOO IIO

crank-arm h. Vith this arrangement the said lever is connected with both the land and furrow side wheels,so as to control both wheels simultaneously, and with the provision of the rock-shaft H and the sliding connections the 'furrow-side wheel can be adjusted laterally without disturbing or interfering with the proper operation of the power-transmitting connection between said lever and the furrow-side wheel. In other words, this furrowside wheel may be adjusted laterally without moving the link fw and the crank-arm h out of alinement with the lever and without causing any of the different parts to cramp or bind. The crank-arm h is preferably connected with the upper end of the standard by a link or rod 71,6. vVith this arrangement when the lever f7 is thrown forward the plow-beam is allowed to settle, as shown in Fig. 2, so as to bring the plow into a working position. During the lowering of the plow the crankaXlef rotates in its bearing and the sleeve or bearing c slides downward upon the standard c. By drawing back the said lever, however, the plow can be raised or lifted from the ground, the backward movement of the lever causing the crank-axle to rotate in such direction as to lift the plow-beam and also causing the rock-shaft H to rock in a direction to in effect pull the sleeve or bearing c upward upon the standard c. Thus while, as stated, the land-side wheel D is capable of independent control or relative adjustment the two wheels are also capable of simultaneous control or adjustment relatively to the plow and beam through the manipulation of a single lever. Furthermore, although the relative movement between the furrow-side wheel and the plow-beam is controlled by the lever, which is also capable of controlling the relative movement between the land-side wheel and the plow-beam, the furrow-side wheel is still free to t-urn with the tongue and follow the line of travel. The rear trailing or caster wheel E is preferably provided with a stem or spindle e, arranged to turnin a sleeve or bearing e. lVith further respect to the said bodily raising and lowering of the plow the said sleeve or bearing e is preferably connected with the rear portion of the plowbeam by means of upper and lower links e2 and e3. These links, it will be observed, are preferably arranged in pairs, one at each side of the plow-beam and sleeve or bearing, and one of the upper links c3 is preferably provided with a downwardly-extending leverarm e4. The link e3 thus provided with a lever-arm e4 is adapted to serve as a bellcrank. The rear and downwardly-extending end portion ofthis bell-crank is connected with the lever f7, preferably through the medium of a link or pull rod e5. This link or rod is preferably arched, as shown in the drawings, so as to provide suitable clearance between its under side and the moldboard of the plow. The lever j"T is preferably provided with a relatively short and downwardly-extending arm f, to which the forward end portion of this link or pull rod c5 is pivotally connected. It will also be observed at this juncture that the forward end of this link or rod is preferably connected with the forward portion ofthe plow-beam by means of a spring e6. The drivers seat I is preferably mounted upon the said sleeve or bearing e'. In this way the weight of the driver or operator is sustained by the rear trailing or caster wheel, and in raising the plow from the ground the plow and beam only are lifted and not the operator or driver. For the pur- Vpose of adjustment the rear end portion of this link or pull rod e5 can be reduced and provided with a screw-threaded portion e7, adapted to engage a turnbuckle or adjusting-nut cs. This turnbuckle or adjustingnut e8 is pivoted to the rear and downwardlyextending arm of the bell-crank and can be removed and rotated for the purpose of either lengthening or shortening the said link or rod. With this arrangement the rear trailing or caster wheel, as well as the forward supporting-wheels, can be controlled by the lever f7. When the said lever is thrown forward, as shown in Fig. 2, the links forming the swinging connections between the casterwheel and plow-beam permit the plow to fall,

the relative movement between the caster-` wheel and the plow being upward, as far as the said wheel is concerned. When the said lever is drawn back, however, the pull exerted by the rod c5 upon the bell-crank causes the latter to lift the plow and rear portion of the plowbeam, the movement on the part of the caster- IOO wheel then being downward, relatively speaking. The said links @zand esform a serviceable and effective swinging connection between the plow-beam and the caster-wheel, and with the arrangement involving links located at either side the requisite strength and rigidity are secured without interfering with the relative movementbetween the caster-wheel and plowbeam. In other words, these links permit the plow and plow-beam to rise and fall readily and in the desired manner, but are so located and arranged as to effectively prevent any lateral play or movement of the sleeve or bearing e' relatively to the plow-beam. In this way the plow, although of the sulky or wheeled type, has practically the strength and rigidity of an ordinary walking-plow. The lever f7 has full control of all three wheels, so that the plow is raised and lowered by manipulating a single hand-lever. In raising the plow the spring c contributes to the power supplied through the lever f7 and tends to hold the plow in an elevated position. As previously stated, the arrangement is preferably such that the caster-wheel is prevented from swinging sidewise While the machine is going straight ahead, but is automatically released as soon as the tongue is swung to one side. For example, the upper end of the caster-wheel stein may be provided with a laterally-extending crank-arm` IIO e, and this crank-arm can be connected with the tongue by means of a rod ew. y The for-v ward end of this rod is preferably arranged to engage a transversely-extending slot g in the casting, which forms a part of the connection between the tongue and the spindle c. A hinge or pivot g is preferably provided between the tongue and the portion g2 having the said slot g. With this arrangement the tongue is free to swing up and down without changing the position of the portion g2. The rear end of the rod el() is preferably threaded and adapted to engage a threaded pivot e11 carried at the end of the arm e9. With this arrangement the stem e will be held from turning while the machine is running straight ahead, as shown in Fig. 3. When the tongue is swung to one side, however, the forward end of the rod e1@ is free to slide back and forth in the slot g, thereby automatically releasing thecaster-wheel and permitting the latter to swing freely from side to side-as, for example, in altering the course of travel or turning the machine around. While the machine is running straight ahead there can of course be no longitudinal or end movement on the part of the rod ew, and therefore the connection between the tongue and casterwheel operates at such time to prevent the caster-wheel froml swinging to one side; but when the tongue and the furrow-side wheel are turned t0 one side then the slot g permits free longitudinal or end movement on the part of the rod elo, and consequently the casterwheel, as stated, is free to swing to one side and to trail loosely in the desired manner. With respect to this arrangement whereby the tongue has a certain amount of control over the rear caster-wheel it will be observed that the lowerlinks e2 are considerably shorter than the upper links e3. This is for the purpose of securing a backward tilt on the part of the caster-wheelspindle when the plow is raised from the ground. In this way the raising and lowering of the plow does not tend to force or swing the caster-wheel to one side as a result of the shortened distance between the casterwheel spindle and the plow-beam. This will be readily understood by referring to Fig. 6, wherein it will be seen that the plow is raised from. the ground and that as a result of the relative proportions of the upper and lower links the casterwheel spindle is inclined slightly to the rear. This has the effect of practically leaving the point of connection between the rod elo and the crank-arm e9 where it was before the plow was raised from the ground-that is to say, by allowing the caster-wheel stern to tilt the rod elo is not allowed to exert a rearward push, which would result in an undesirable cramping or swinging of the caster-wheel against the edge of the furrow. Consequently, as stated, the arrangement permits the tongue to be connected with and have a certain amount of control over the rear caster-wheel, and. at the same time the arrangement prevents the raising of the plow from throwing the casterwheel. out of alinement.

It will be readily understood that any suitable draft appliance can be employed and that, if desired, the plow can be provided with the usual colter-wheel J.

With further reference to the raising and lowering of the plow it will be seen that the angle of the arm f and connections and relative arrangement are such that the limit' of the downward adjustment of the plow-heel relative to the caster-wheel is substantially reached when the said leverisin the position shown in Fig. 2. In other words, the said lever when thrown forward from the position shown in Fig. 2 will not operate to further depress the heel of the plow relative to the rear wheel-that is, to any greatextent-inasmuch as such forward movement of the lever produces little further rearward movement on the part of the link e5. It will be observed, however, that a forward movement of the lever f7 from the position shown in Fig. 2 operates to further depress the toe or point of the plow, owing to the relative arrangement of the said lever and the crankarm h. In this way the plow can be lowered to any extent, and whether the plow is operated near the surface of the ground or at some depth below the point or toe of the plow will always be below the heel. This is particularly advantageous in making the first furrow, for in such case the plow must be lowered below the front furrow-wheel, and at such time if the plow-point is above the heel the draft will tend to pull the plow out of the ground. However, with the arrangement by which theplow-point is always below the heel when the plow is in the ground a satisfactory and efficient operation of the plow is always insured, regardless of whether the plow is operating near the surface of the ground or at a considerable depth. In Fig. 7 the plow is shownatthelimitofitsdownward adjustment, and it will be seen that this extreme downward adjustment has been accomplished without producing furtherrelative movementbetween the plow and the rear trailing or caster wheel. In other words, the relative arrangement of the lever and the connecting parts is such that the throw of the lever beyond a certain point limits or conflnesthe relative movement to the forward supporting-wheels, inasmuch as this extreme adjustment of the lever produces practically no further tilt on the part of the bell-crank. In this way the two forward supporting-wheels can be adjusted to the same level, and by then throwing the lever forward to the full extent of its adjustment the plow will be lowered to an extent to permit the makingofthefirstfurrow,as showninFig.7. Thus it will be seen that a wheeled or sulky plow constrncted in accordance with my invention is of minimum weight and number of parts, considering the various adjustments and operations of which the plow is capable, and that the requisite strength and rigidity are secured IOO IIO

without the necessityof providing any framework. Furthermore, the construction and arrangement permits the plow to be raised to a greater extent than is usual with plows of this type, and in addition this high lifting of the plow is accomplished through the medium ot' a single hand-lever. Both levers are, however, as illustrated, con venientlylocated, and the arrangement is such that the driver or operator can readily and easily control all of the wheels. The construction and arrange- 1nent,although simple and involvingfewparts, permits any and all of the adjustments which are known to be necessary or essential to the proper working ot a plow of this type.
