SPECIFICATION forming part of Letters Patent No. 713,086, dated November 11, 1902. Application filed March 29, 1902. Serial No. 100,510. (No model.)

To all whont it may concern/.- 1

Be itknown that I, J OSEPH A. FRENIER, 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 Sulky-Plows, of which the following is a specification.

My invention relates to that construction of wheeled or sulky plow involving a plurality of supporting-wheels having shifting connections with the plow-beam. In a plow of this character suitable means are usually provided for causing a relative shift between the wheels and plow, so as to permit the lat-i It is also usuter to be raised and lowered. ally the practice to employ a construction and arrangement whereby one or more of the wheels can be controlled independently of the others.

The particular t-ypeof sulky-plow to which my invention relates is constructed with front and rear furrow-wheels and also with.

a land-side wheel. In operation the rear furrow-wheel travels behind 'the' plow in the furrow being made, while the front furrowwheel travelsin the previous furrow. The land-side wheel,which is preferably controlled 1 either simultaneously with or independently of the other wheels, is arranged to travel upon" the unplowed surface of the ground. With. this arrangement the wheels can be easily and readily controlled, and the machineis characterized by practically all of the known and approved methods ofoperation.

Generally stated, it is the object of my invention to provide a simple, efficient, and comparatively inexpensive wheeled or sulky plow of the foregoing type.

A special objectis to provide an improved shifting connection between the forwardfurrow-wheel and the plow-beam. j

Another object is to provide a similar improved connection between the plow-beam and the rear furrow-wheel.

A further object is to provide a simplified and improved arrangement for controlling the land-side wheel independently of the other wheels.

Another object is to provide an improved construction whereby the front furrow-wheel,

furrow being made.

- although tilted or inclined outwardly, may be adjusted laterally in a horizontal plane.

In addition it is also an object to provide certain details of construction and features of improvement tending to increase the general efficiency and to render a plow of this type more serviceable and reliable than heretofore.

To the foregoing and otherusefulends my invention consists in matters hereinafter described and claimed.

In the accompanying drawings, Figure l is a side elevation of a wheeled orsulky plow embodying the principles of my invention. In this view the relative adjustments between theplow and supporting-wheels are such as to permit the plow to make the first furrow. In such case, as will be observed, the land-side and front furrow wheels travel upon the unplowed surface of the ground, while the rear furrow-wheel travels behind the plow in the Fig. 2 is a View similar to Fig. 1, but showing the subsequent relative adjustmentof the plow and wheels, so as to permit the front furrow-wheel to travel in the previous furrow. Fig. 3 is a detail sectional view ofthe rack-and-pinion connection between the front furrow-wheel and the plow- 'beam. Fig. 4 is a view similar to Figs. 1 and 2, but showing the plow lifted out of the ground.

Fig. 5 is a detail sectional view showing the rack-and-pinion connection between the plowbeam and the rear furrow-wheel. Fig. 6 is a detail of the construction by which the front furrow-wheel although tilted outwardly may be shifted laterally in a horizontal plane. Fig.

7 is a detail sectional view on line 7 7 in Fig. 5.

Fig. 8 is a plan of the plow shown in Figs. 1, 2,and 4, certain portions being shown in section and broken away for convenience in illustration. Fig. 9 is a section on line 9 9 in Fig. 8, showing the two relatively shifting castings which form the medium of connection between the front furrow-wheel and the'plowbeam. Fig. 10 is a front-elevation of the adjustable connection between the spindle or crank-arm of the land-side wheel and the crank-shaft. Fig. 11 is a section on line 11 11 in Fig. 8, showing the device illustrated by Fig. 10.

As thus illustrated, my improved wheeled or sulky plow comprises, preferably, a plow A, which can be of any suitable form or pattern and which is provided with the usual plow-beam B. As will be observed, all supplemental and unnecessary framework is dispensed with, the supporting-wheels being connected directly to the plow-beam. Hence, as will be observed, the connection between the forward portion of the plow-beam and the front furrow-wheel 0 consists, preferably, of two relativelysliding castings or members 0 c,

tlTc'fbrmer mounted upon the spindle c of the forward furrow-wheel and the latter upon the forward portion of the plow-beam. The casting 0 is, it will be observed, fitted to slide vertically upon the casting or other member 0. The oppositely-arranged vertical surfaces of these two castings or members are provided with rack-teeth c and 0. These two opposing racks are engaged by the pinion c, which, it will be seen, is arranged in the boxlike structure composed of the two relatively sliding or shifting members. Thus arranged it will be seen that a rotation on the part of this pinion will cause a relative shifting or sliding movement on the part of the two castings or members, a rotation of the pinion in one direction causing it to rise bodily, carrying the casting c and the plow-beam with it. A rotation of the pinion in the opposite direction, however, permits it to move bodily downward, allowing the casting c of the plowbeam to settle to a lower plane. During this bodily rise and fall on the part of the pinion its short shaft 0 moves up and down or plays in the slots 0 in the side walls of the casting c. Any suitable arrangement may be employed for rotating this pinion; butas a matter of further and special im provement this rotation is secured by connecting a lever D with the crank-arm by means of a link a. The said crank-arm, it will be observed, is mounted at the end of the pinion-shaft c. The said lever is preferably rigid with a transverselydisposed crank-shaft E, which carries the land It will be readilyseen that with side wheel F. this arrangement the rotation of the said pinion and the consequent relative movement between the front furrow-wheel and the plowbeam can be secured by a forward or back movement of the lever D. In asimilar manner the shifting connection between the rear furrow-wheel Gand the rear portion of the plow-beam is secured through the mediumof two similar sliding or relatively shifting castings g and As in the previous case, the casting g, which is secured to the plow-beam, is fitted to slide up and down on the casting g, which provides a bearing for the verticallydisposed spindle g of the caster-wheel. The casting g is provided with a vertically-disposed rack 9 while the casting g is provided with a similar and oppositely-arranged rack 9 Between these racks is interposed the pinion g, which is provided with a short shaft 9 A relative and vertical shift or sliding moveg of the said pinion moves orplays in the slots 9 formed in the side walls of the casting g. The said axis or shaft 9 is preferably provided with a crank-arm 9 which is connected with the lever D by means of a link 9 With this construction and with the relative arrangement of parts shown the rear portion of the plow and beam can be raised and lowered by swinging the lever D so as to rotate the pinion g one way or the other. A movement of the lever in one direction will, it will be observed, cause the pinion to move bodily upward, carrying the casting g and the rear portion of the plow-beam with it, while a rotation of the pinion in the opposite direction will cause it to move bodily downward, allowing the plow-beam to settle to a lower plane. Both rotary pinions being connected with the lever D, it follows that the two furrow-wheels can be controlled simultaneously. It will be observed, however, that through the provision of the spring 9 the forward movement of the lever D beyond a certain point raises the forward furrow-wheel relatively to the plow without causing any further relative upward movement on the part of the rear furrow-wheel. In this way the said lever can be thrown forward from the position shown in Fig. 2, so as to relatively raise the front f urrow-wheel above the plow, but, as stated, without shifting the position of the rear furrow-wheel relatively to the plow.

The land-side wheel F, as will be observed, is preferably mounted upon the spindle or crank-arm f, which is swingingly mounted upon the transversely-disposed crank-shaft E. As a matter of further and special improvement and in order to permit the said land-side wheel to be controlled independently of the other wheels the end of the shaft F is preferably squared to receive a segmental rack f. A collar f is also preferably secured upon said shaft. A collar f on the upper end of the spindlef is preferably arranged between the rack f and the rigidlysecured collarf It will be observed that the lever F is secured to and rigid with the said loosely-mounted collarf The said lever is provided with a suitable locking-bolt adapted to engage the rackf. With this arrangement the lever B" can be grasped and employed for controlling or adjusting the land-side wheel independently of the other wheels. It will be readily understood that any suitable means can be employed for holding the lever D at any point in its adjustment-as, for example, by providing it with the usual locking-bolt adapted to engage the rack d, which can be secured to the plowbeam. WVith this arrangement the lever D can be grasped and employed for either controlling all three wheels simultaneously or for controlling the front and rear furrowwheels independently of the land-side wheel. The arrangement in this way permits the plow to be readily raised and lowered with the least possible exertion. Furthermore, the construction and arrangement permit the wheels to be given any and all of the known or approved adjustments relatively to the plow. In this way it will be seen that the plow is characterized by practically all of the known and approved methods of operation, while at the same time the weight and number of parts are reduced substantially to a minimum. In addition the shifting connections particularly between the front and rear furrow-wheels are of such character as to insure against the play or lateral yielding which might resultfrom loose joints or a faulty construction. It will also be observed that, as previously explained,

the arrangement entirely obviates the necessity of employing any framework.

As a matter of further and special improve-- ment the spindleor standard of the forward furrow-Wheel is preferably made in two sections, the upper section being vertical, as shown, while the lower section 0 is horizon 'A set-screw 0 can be employed for holding the lower spindlesection against movement. In this way the front furrow-wheel can be shifted relatively to the plow, so as to change the width of the furrow. This lateral adjustment of the front furrow-wheel is obtained, it will be seen, without moving it up or down. In other words, although tilted or inclined outwardlyit may be adjusted laterally in a horizontal plane.

As afurther advantage, it will be seen that I the caster-wheel can be swung clear around,

inasmuch as it can be brought readily below the overhangingportion of the casting g. This rear furrowwheel, as shown, is also preferably tilted or inclined away from the land side, so as to enable it to travel properly in the furrow. In order to prevent this rear furrow or caster-wheel from turning while the machine is running straight ahead, the cran karm H on the upper end of the spindle g is connected with the rear end of the tongue I casting i. When the machine is running straight ahead, as shown in Fig. 8, the casting t' and the rod it keep the caster-wheel in the position shown in said figure. When the machine is swung to one side, however, as in changing the course of travel or in turning around, then the forward end of the rod 71 is free to move or slide back and forth in the slot 2', and consequently the wheel G is free to turn in the manner of an ordinary caster wheel. In other words, the rear caster-wheel is automatically released as soon as the tongue is swung to one side. Thespindle g of this caster-wheel is, it will b'eunderstood, mounted to turn freely in the rearwardly-proj ecting or overhanging portion of the casting g. It will alsobe seen that the spindle of the forward furrow-wheel is mounted to turn in sleeves or collars 0 preferably formed integral with the casting c. As a means for preventing relative shift or sliding movement between 7 this spindle and the casting c, a collar 0 is interposed between the collars 0 and keyed or otherwise suitably secured to said spindle.

Any suitable arrangement can be employed necessary adjustments -that is to say, those adjustments which are necessary in View of certain approved methods of operation-and that at the same time the construction, while simple and involving no special framework,

is neverthel'esssuch as to insure the greatest strength and rigidity. Furthermore, the rear furrow-wheel maintains its distance from the plow throughoutthe scope of its adjustments.

This prevents the rod h from turning or.twis t-v IIO ing the rear caster-wheel when the plow is raised from the ground.

\Vith the sliding connection employed between the rear wheel.

and the plow-beam the said wheel does not move toward and away from the plow when the latter is moved up and down. This is of great advantage, as it permits the plow to be I h to twist or turn the caster-wheel. tion it will be seen that my invention contemplatesaleverarranged forsimultaneously controlling all three wheels and having a raised and lowered without causing the rod In addispring or-yielding connection with the rear wheel. As shownin Fig. 5, the crank-arms for the pinions can be adjustably connected: with the latter, so as to permit the angle of the crank-arms to beadjustahly changed for the purpose of securing the proper relative movements. ForexamplefinFig.7thecrankarm 9 is adjustably connected withtheshort.

stud or shaft g by means of a toothed formation, such as shown at g, so as to permit the said crank-arm to be set at any angle or position relatively to the pinion. In this way the connections between the lever D and the pinions can be nicely adjusted in order to, as stated, insure the desired and proper relative movements and adjustments.
