SPECIFICATION forming part of Letters Patent No. 766,258, dated August 2, 1904,

Application filed August 22, 1902.

To (all w/wm, it TH/(l/Z/ concern:

Be it known that 1, James B. JARMIN, a citizen of the United States of America. and a resident of Davenport, Scott county, Iowa, have invented a certain new and useful Improvement in Plows, of which the following is a specification.

My invention relates to wheeled or sulky plows of that type in which all framework is dispensed with and in which the front and rear furrow-wheels and also the land-side wheel are connected directly with the plowbeam. It is usually the practice in a plow of this character to provide shifting connections between the plow-beam and the wheels and also to provide one or more levers for controlling the adjustments of these wheels relatively to the plow and beam, so as to permit the driver to raise and lower the plow.

Generally stated, it is the object of my invention to provide a simple, comparatively inexpensive, and highly-efiicient wheeled plow of the foregoing character.

A special object is to provide an improved form of shifting connection between the plow-' beam and the rear furrow or caster wheel.

Another object is to provide an improved system of leverage for simultaneously controlling all of the wheels.

A further object is to provide an improved lever arrangement whereby the driver may employ a foot-lever in conjunction with one or more hand-levers for controlling the wheels.

Another object is to provide a plurality of improved shifting connections between the wheels and plow-beam and to arrange the shifting connections in such manner that the plow may be raised and lowered without lengthening or shortening the wheel-base.

It is also an object to provide certain details and features of improvement tending to increase the general efficiency and serviceability of a wheeled plow of this character.

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

In the accompanying drawings, Figure 1 is a furrow-side elevation of a wheeled plow Serial No. 120,677. (No model.)

embodying the principles of my invention, the plow and beam being shown raised from the ground. Fig. 2 is a similar elevation, but showing the plow lowered into the ground. Fig. 3 is a land-side elevation of my improved wheeled plow, the plow and beam and other parts being in the same position as illustrated in Fig. 2. Fig. A is a plan of my improved plow with the different parts in the relative positions shown in Fig. 2. Fig. 5 is an enlarged vertical section on line 5 5 in Fig. 2. Fig. 6 is a detail section on line 6 6 in Fig. A.

Fig. 7 is an enlarged horizontal section on line T 7 m Fig. 3. Fig. 8 is an enlarged vertical detail section of the shifting connections between the plow-beam and rear furrow or caster wheel. Fig. 5) is a horizontal detail section on line 9 S) in Fig. 8. Fig. 10 is a detail cross-section on line 10 10 in Fig. 3. Figs. 11 and 12 are detail views illustrating the construction of the jointed or reticulated connection between the foot-lever and the crank-axle.

As thus illustrated my improved wheeled plow comprises, preferably, a plow A and beam B. These can, it will be understood, be of any suitable known or preferred form.

The wheels for supporting the plow and beam preferably comprise front and rear furrow-wheels O and l) and also a land-side wheel E. The said front furrow-wheel is, it will be observed, preferably mounted upon the lower outturned end portion of the stem 0. In a similar manner the rear furrow or caster wheel l) is prcferabl y mounted upon the lower end of the caster-wheel stem 1/. The land-side wheel, however, can, if such is desirable, be mounted upon the transversely and horizontally disposed crank-axle E.

The shifting connection between the front furrow-wheel and the plow-beam can consist of a bracket 0', provided with a sleeve portion adapted to slide up and down upon the stem 0. \Yith respect to the adjustment of this wheel relatively to the plow-beam the said bracket can be adapted to provide a bearing for the short shaft r, having a toothed wheel c mounted upon its inner end. The outer end of this shaft can be provided with a crankarm 0", the latter being connected by a link or pitman 0 with the casting 0 mounted upon the upper end of the stem 0. The tongue F is preferably pivotally secured to this casting 0 so as to permit the team to control the front furrow-wheel.

My improved shifting connection between the plow-beam and the rear furrow or caster wheel 1) preferably consists of a bracket Gr, having its forward end secured to the curved portion'of the plow-beam and having its rear end portions 9 adapted to slide up and down upon the pipe g, which latter, it will be observed, is mounted upon the cylindric stem of the said caster-wheel. With the provision of the bolts and the slots 9 it will be seen that these portions 9 of the bracket can be ad justed laterally relatively to the balance of the machine, so as to permit the rear furrow or caster wheel to be adjusted laterally relatively to the plow in accordance with the. character of the soil. The drivers seat H can be mounted upon the sleeve or collar h, which latter is preferably secured to the pipe 9. The lower end of the said pipe normally rests upon the collar g, which is secured upon the stem of the caster-wheel. An arm y can be clamped upon the lower end of the pipe, in which the caster-wheel stem is free to turn, and the forward end of this arm can be con nected with the cranks g by means of the vertically disposed pitman 9 A toothed wheel 1 is preferably mounted upon the outer end of the crank-shaft carrying the cranks g l/Vith respect to the lateral adjustment of the rear furrow or caster wheel the arm 9 can be made in two parts, as shown in Fig. 9,-and with the provision of the bolts g and the slots the two parts of this arm can be adjusted laterally relatively to each other when it becomes desirable to shift the caster-wheel to one side or the other, according to the character of the soil in which the plow is to operate.

As shown more clearly in Fig. 4, the upper end of the rear furrow or caster wheel stem is preferably provided with a laterally-eX- tending crank-arm 5 while the upper end of the front furrow-wheel stem is provided with a similar arm 0 These two laterallyeXtending arms are preferably connected by a rod 1. Vvith this arrangement the tongue, it will be seen, is connected to control both the, front and rear furrow-wheels. At the same time it will be seen that the two vertically-disposed stems which are thus turned or rotated by the tongue afford standards or uprights upon which the plow structure is free to slide up and down when it is desirable to raise or lower the plow.

ith respect to the simultaneous adjustment of the front and rear furrow-wheels relatively to the plow and beam the sprocketwheels 0 and g are preferably connected by a chain belt J. WVith this arrangement a simultaneous rotation of the two toothed or sprocket wheels can be had for the purpose of simultaneously operating the two shifting connections between the front and rear furrow-wheels.

The land-side wheel E is, as stated, preferably mounted on acrank-axle, which latter is supported for rotation in the bracket-bearing a. This bearing, it will be observed, is secured to the plow-beam and extends outward to the land side of the plow. With respect to a desirable independent adjustment or control of the land-side wheel the said crankaXle is preferably provided with a looselymounted crank-arm e and also with a rigidlysecured rack 6 The lever e is preferably rigid with the swinging arm a and is thus adapted for controlling or adjusting the landside wheel independently of the balance of the machine. The usual locking-bolt on the said lever is, it will be understood, arranged to engage the said rack, and in this way the said wheel can be adjusted and locked in any position relatively to the transverse or straight portion of the axle.

Now with a view to providing means whereby a foot-lever can be employed for simultaneously controlling all three wheels, so as to permit the driver to raise and lower the plow without using either hand, I provide the crank-axle with a rigidly-secured arm K and connect this arm with the foot-lever L by means of'a linkk. The joint or reticulation between this link and the arm Z of the footlever is, it will be observed, of a character as to readily break joint upward, but of such character as to be positively locked or held against movement in a downward direction. This will be readily understood by referring to Figs. 11 and 12, wherein it will be seen that the arm of the foot-lever can be provided with a lip or projection Z, adapted to extend over the link. This jointed portion of the system of leverage thus provided can also be provided with a foot-piece Z to enable the driver to return the parts to the position shown in Fig. 3that is to say, to permit the driver to press the jointed connection forward and downward from the position shown in Fig. 1, so as to force the plow into the ground and lock it against rising. When the link K and the foot-lever L are in the positions shown in Fig. 3, it will be seen that the joint thus provided between the two serves to lock the plow against rising. With this arrangement the driver can raise the plow from the furrow by simply placing his foot upon the lever L, so as not only to rotate the crank-axle, but so as also to operate the shifting connections between the front and rear furrow-wheels. This adjustment of the front and rear furrow-wheels through the medium of the foot-lever and the crank-axle is preferably accomplished by providing the outer end of the axle with an arm M, which is IOC IIC

connected by the plate m with the link beltJ, extending around the two sprocket-wheels. \Yith this arrangement it will be seen that the driver in rotating the crank-axle by means of the foot-lever must necessarily cause a shifting movement on the part of the link belt and a consequent rotation of the two sprocketwheels, the latter resulting, of course, in an up-and-down sliding movement of the plowbeam upon the stems of the front and rear furrow-wheels. Thus it will be seen that the foot-lever can be'employed for simultaneously controlling all three wheels, so as to raise and lower the plow, and that the auxiliary hand-lever can be employed for independently controlling the land-side wheel, so as to permit the driver to readily level up the plow. In thus raising and lowering the plow it will be seen that the driver does not lift his own weight, inasmuch as the seat is supported solely by the rear furrow or caster wheel through the medium of the sleeve or pipe 7. In this connection it will be seen that the said pipe or sleeve is held positively against any rotation in the casting G by reason of the pitman being held firmly against lateral movement by the two cheeks or parts Thus the plow-beam is free to slide up and down upon the stem of the rear furrow or caster wheel, and at the same time the said wheel supports the weight of the driver without causing the drivers seat to swing from side to side with the motion of the wheel. In other words,when the course of the machine is altered the seat remains in its proper position and does not turn when the two wheels are turned by a lateral defiection of the tongue.

In order that the driver may, if such is necessary or desirable, employ either hand to assist the foot-lever in raising or lowering the plow, 1 provide the crank-axle with a looselymounted hand-lever N. This handdever is provided with a couple of locking devices, as shown in Fig. 2, one adapted to engage the upper end of the arm- M, which latter, as stated, is rigid with the crank-axle, and the other engages the rock 11. on the plow-beam. \Vith this arrangement this auxiliary lever can be locked to the crank-axle tl'irough the medium of the arm M, and in such case it can be grasped by the driver and employed for rotating the crank-axle, and thereby causing the described simultaneous adjustment or control ofall three wheels. As another advantage this hand-lever can be simply employed as a stop or gaging device for regulating the depth to which the plow is adjusted. For

ward inovementof the plow. Thus the handlever N can be employed as a gage or stop for regulating or determining the depth of the furrow.

The two vertical standards provided by the stems of the front and rear furrow-wheels permit the plow-beam and the rigid structure connected with it to slide up and down vertically without in any way lengthening or shortening the wheel-base. In other words, the two stems always remain parallel regardless of the position of the plow, and the distance between these two stems also remains constant, thereby insuring a wheel-base which remains the same at all times. In this way the plow is readily and easily raised and lowered without varying and changing the distance between the front and rear furrowwheels, and thereby, as stated, without altering the character of the wheel-base.

\Vith respect to the raising and lowering of the plow it will be observed that the crankarm 0 can be somewhat longer than crank g, so as to give the point of the plow considerably more up-and-down movement than the heel. In this way the plow when raised from the ground will have its toe or point held in a more or less elevated position relative to its heel, and when in the ground the plow will have the requisite or desired dip-that is to say, the plow-point will always be below the heel when the plow is in the ground, thereby insuring against drag or unnecessary friction.

\Vith further respect to the shifting connections between the rear furrow or caster wheel and the plow-beam it will be seen that the construction is such as to insure a high degree of rigidity and strength, thereby insuring against loose joints and the play or lostmotion which might otherwise result from long or continued use of the plow.

\Vith the provision of the foot-lever the driver can easily raise and lower the plow without letting go of the lines, and at the same time and with the provision of the second aux iliary lever the driver can, if necessary, use one hand for simultaneously controlling all three wheels. substantially all of the adjustments which are known to be necessary or desirable to the proper working of a plow of this character, and at the same time the construction is light and simple and in addition of a character to insure a high degree of strength and rigidity. Obviously, however, there are many advantages in my construction which will be instantly recognized by those skilled in the example, this lever can be thrown forward to the desired point and can then be allowed to I remain in such position while the plow is 3 raised and lowered by means of the footlever. In such case the plow can only be lowered until the arm M strikes the locking device on the lever, and in this way, as stated, I this lever N acts as a stop to limit the downi art and which for this reason I need not mention.
