suLKY-PLOW.

SPECFICATION forming part of Letters Patent No. 464,635,dated December 8, 1891.

Application filed February 13 1891. Serial No. 381,322. (No model.) l

To all whom it may concern:

Be it known that we, LUTHER C. JACKSON, of Wolfe City, Hunt county, and JOHN F. REIGER, of Dallas, in the county o'f Dallas and State of Texas, citizens of the United States, have invented a new and useful Sulky- Plow, of which the following is a specification.

This invention relates to sulky-plows, and it has for its object to provide a device of this class which shall be simple in construction,

inexpensive, and easily manipulated, and in which the plow and the frame may be readily adjusted, when desired, to any position with relation to each other that shall insure lightness of draft and steadiness of motion.

Vith these ends in view the invention consists in the improved construct-ion, arrangement, and combination of parts which will be hereinafter fully described, and particularly pointed out in the claims.

ln the drawings hereto annexed, Figure 1 is a top plan View of a sulky-plow constructed in accordance with our invention. Fig. 2 is a rear elevation of the same. Fig. 3 is a side elevation. Fig. f1 is a side elevation taken from the opposite side. Fig. 5 is a front elevation. Fig. 6 is a transverse sectional view taken on the line 6 6 in Fig. 1 and looking in a rearward direction'. Fig. 7 is a detail view of the mechanism for adjusting the plow. Fig. 8 is a perspective detail view of the means for adjusting the shaft carrying the main Fig. 9 is a detail view of the mechanism for adjusting the front end of the plow-beam.

Like numerals of reference 4indicate like parts in all the figures of the drawings.

The frame of our improved sulky-plow is composed of two straps of steel 1 1, which are bent so as to form a frame of the general shape and outline shown in the drawings hereto annexed. The said frame, as will be seen in the drawings, is composed of the front and rear pieces 2 and 3, which latter is provided with an arch 4 and a side piece 5, connected by an oblique corner-piece 6 with the front piece of the same. The two strips 1 1,

of which the frame is composed, are bent to the desired shape and are connected with each other by means of bolts 7 upon which spacing blocks or washers 8 are mounted so as to hold the strips 1 1 at the desired distance apart parallel to each other. We desire to state that while itis preferred that the nected by a rod or shaft 9, having suitable bearings in the ends of said frame-pieces. The said shaft is provided with laterally-extending arms or brackets 10, having segmental slots 11, provided with corrugations or scal-l lops 12, adapted to register with an inclined slot 13, formed in each of the frame-pieces 2 3, adjacent to the arms or brackets 10.

14 14 designate bolts that pass through the slots 13`and through the slots 11 in the arms or brackets 10 and serve to connect the latter adjustably with the frame, thus enabling the shaft 9 to be adjusted, as will be readily understood. The notches or scallops 12 serve to engage the bolts 14 after the latter have been adjusted, thus holding them securely and preventing accidental displacement. The rod or shaft 9v is provided with a laterally-extending spindle 15, carrying the` main-transporting-wheel 1G. The frame is provided between the arch 4' and the rod or @a a longitudinal brace 17, which ser c.. t., s. the frame without materially increasing the weight. Between the portion of the straps 1 1 which form the side bar of the frame are pivoted levers 18, the lower ends of which carry the swiveled caster-wheels 19, which are of ordinary construction. The upper ends ot' the levers 1S are connected by a pivoted rod 20. An' operating-lever 21, which is pivoted between the straps 1 1, is likewise pivotally connected with the connecting-rod 2,0, so that by manipulating the said lever the levers 18 may be adjusted to raise or lower the casterwheels 19 with relation to the frame. -The hand-lever or operating-lever 21 is provided with a suitable catch 22, adapted tol engage any one of a series of notches 23 in a ratchetbar 24, which is suitably attached to the frame of the machine. The said lever and the parts operated thereby may thus be conveniently retained in any position to which they may IOO be attached. B y the use of two caster-wheels instead of a single one, which has been commonly used of this class, the frame is prevented from swaying and vibrating during Operation, and we are thus enabled to dispense with the use of a tongue. At the same time, the said caster-wheels being swiveled the machine may turn very shortly at the corners ot' the lield and maybe operated in the easiest and most efficient manner.

' The rear piece 3 of the frame is provided with bearings for the ends of a shaft 25, having a crank 26, the sides of which are con nected by a detachable bolt 27. One end of the crank-shaft 25 has a hand-lever 2S, provided with a catch 29, adapted to engage a ratchet-bar 30, which is suitably attached to the longitudinal brace 17 of the frame.

3l designates the plow-beam, which is constructed in the usual manner with a standard 32, to which the plow 33 is attached. The plow-beam is provided with a transverse perforation 34 for the passage of the bolts 27, forming a portion of the crank 26, upon which it is mounted. Tashers 35 are mounted upon the bolt 27 at either side of the plow-beam, which latter may be laterally adjusted upon `the said bolt by moving the washer from one side of the plow-beam to the other. Such adjustment may be conveniently effected by temporarily removing the bolt 27, as will be readily understood.

The front end of the plow-beam is connected by a link or rod 36 with a clip 37, which is mounted between the portion of the straps 1 1, forming the front bar 2 of the frame. Said clip is approximately T-shaped, and is provided with downward-extending iianges 3S, engaging the upper edges of the straps. The latter are provided in their under sides with notches 39 to receive the cross-bar 40 of the clip, which latter may thus be secured against lateral movement in any desired position. The shank 4l of the clip may be screw-threaded at its upper end which extends through the flanged head 42 and provided with a nut a3, thus enabling the said clip to be conveniently adjusted.

It will be seen from the foregoing that the front as well as the rear end of the plow-beam is capable of being laterally adjusted. In addition to this the rear end of the plow-beain may be adjusted by means of the lever 28, attached to the crank-shaft 25, so as to set it at any desired depth. The vertical adjustment of the rear end of the plow-beam may be readily effected while the machine is in opertion by the driver, whose seat 4:4 is suitably attached to the arch et of the rear cross-bar of the frame. The outer end of the frame is supported upon the caster-wheels 19 and maylikewise be readily adjusted by the driver during the operation of the machine. Previous to starting, however, the plow-beam should be adjusted to the desired position. main supporting wheel 16 should also be tilted inwardly by properly adjusting the rod The or shaft 9 to any desired inclination. The object of this is to cause the said wheel to present a certain degree of resistance against the mold-board of the plow which turns the soil in the direction of the said supportingwheel. In very light soil the position of the wheel may be nearly or quite vertical. In waxy or sticky soil the inclination of the wheel should be gaged according to the degree of resistance presented in order to cause the plow to run true and even and in the lightest possible manner.

As will be understood from the foregoing description, the draft is to be applied direct to the front end of the plow-beam, our improved sulky-frame being used without a tongue. The construction of the frame is simple, inexpensive, and eiiicient, and it will be readily understood that a plow of any desired construction-may be used in connection with the sulky-frame.

It is our intention to use a plow having a wooden mold-board which has been found by practice to possess superior advantages over the metallic mold board in shedding the sticky and waxy black soil which is frequently encountered in certain parts of the country.

of a separate application for Letters Patent, and dos not require to be more fully herein described.

IVe have in the foregoing described what we consider to be the preferred construction of our improved sulky-plow; but we desire it to be understood that we do not limit ourselves to the precise construction and arrangement of details herein shown and described; but reserve the right to any changes and modifications, to which recourse may be had without departing from the spirit of our invention.
