PLOW.

SPECIFICATION forming part of Letters Patent No. 464,015, datedDecember 1, 1891.

Application filed October 3l, 1889. Serial No. 328,785. (No model.)

To @ZZ whom it may concern.-

Be it known that I, ASA M. FITCH, a citizen of the United States, residing at Seymour, in the county of Jackson and State of Indiana, have invented certain new and useful Improvements in Plows; and I do hereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates, generally, to plows, and particularly to that class thereof in which an adjustable pivoted truck is employed at the forward portion of the plow-beam for permitting its wheels to pass over the ordinary obstacles encountered in plowing without altering the depth of thepenetration of -the plow proper or straining the parts of the same or its frame, and, consequently, for plowing with equal ease and accuracy in rough and smooth lands,and in which a wheel is employed in rear of the plow proper for running in the bottom of the furrow and steadying the same, for supporting said plow while being upon the surface of the land and Inoved from place to place, for forming a fulcrum for raising the plow from the surface of the land by pressing upon the handles, and for forcing said plow a greater or lesser depth into the ground by adjusting its support; and my invention is especially designed as an improvement upon the one disclosed in Letters Patent granted to me May 12, 1885, No. 317,754., although it is equally applicable to any plow whereon its employment is desired.

The objects of my invent-ionare, first, to provide improvements in the construction of the truck for the forward portion of the plowbeam and in the devices for adjustably securing said truck to said beam; second, to provide novel and improved means for attaching the rear or furrow wheel and its standard to plow-beams of varying widths; third, to provide novel and improved means for raising and lowering the plow proper and for transferring the furrow-wheel and the lower arm of its standard to a point on a line to the right or left of the upper arm of its standard, as desired, and fourth, to provide novel and improved devices for vertically adj usting the plow proper and the truck, so as to bring them into proper horizontal alignment when it is desired to plow deep or shallow furrows; and it consists in the peculiarities of construction and arrangement or combination of parts hereinafter disclosed in the description, drawings, and claims.

In the accompanying drawings, forming` part of this specification, and in which the same reference-numerals indicate the same parts, Figure 1 represents a partly broken side elevation of a plow with my improvements attached; Fig. 2, a detail perspective view of lthe two-wheeled truck and its attachments; Fig. 3, a detached perspective view of one side of the clip-band and of one of the vertical bars which iits and is adapted to slide therein; Fig. 4, a broken side elevation of the plowbeam and plow-standard, showing also the upper fish-plate, its screw-bolt and nut, and the clips for securing the same to said beam just in rear of said standard; Fig. 5, a detached perspective view of said upper fishplate 5 and Fig. 6, a detail perspective view of the lower fish-plate and the upper arm of the two-part standard for supporting the furrowwheel, secured to one end thereof, showing also the lower end of said upper arm of the standard as provided with an annular series of teeth or cogs upon each side thereof.

In the drawings, the numeral 1 designates the plow-beam, 2 the plow proper, 3 the handles, and LI'the plow-standard, to which and said handles the plow is secured in any suitable manner, all being of any ordinary or preferred construction.

The truck 5, consisting' of the two Wheels (i and the two yokes '7, in the ends of which said wheels are journaled, is applied to the forward portion of the plow-beam 1 and suspended therefrom by the clip-band 8, which is formed with the vertical dovetailed grooves 9 in its sides and with the series of vertical l IOO against said plow-beam, where it is held in place by the nut 16. By the removal of these bolts and nuts and their adjustment to suitable registering holes in the bars 11 and the clip-band S, the truck will be also vertically 1o adjusted, and thus caused to coincide inhorizontal alignment with the plow proper when it is vertically adj usted for plowing to greater or lesser depth. This truck attachment is also applicable to plow -beams of various 15 forms and sizes, either by shaping or cutting the latter to fit the clip-band or by forming the latter to t the beam.

At a point just in rear of the plow-standard 4 is secured the upper arm 17 of the two-part zo jointed standard 1S, to the lower end of the lower arm 19 of which is journaled the furrow-wheel 20, as'shown in Fig. 1. The upper portion of the arm 17 is curved slightly forward and formed at itsfront end with a hori- 2 5 zontal portion 21, which is preferably provided with outwardly-projecting flanges 22 along its upper edges and is fitted within a correspondingly-shaped recess 23, formed in the under surface of the lower fish-plate 24,

3o near the inner end thereof, as shown in Fig.

G. These ends of the [ish-plate and ot' the upper arm 17 of the standard are arranged at right angles to each other, and are additionally or more rigidly held together by means of the nutted bolts 25 passed therethrough.

The lower fish-plate 24 is formed with a central elongated opening or slot 26, which extends lengthwise thereof and is adapted to receive the screw-bolt 27 ,which projects down- 4o ward therethrough from the center of the upper fish-plate 28, and is provided with the nut 29 for rigidly holding said fish-plates together in whatever position they may be adjusted. The upper fish-plate 2S.is formed in its under surface with the recess 28', which is of a width corresponding to that of the lower fish-plate, but is not as long, and within which said Iish-platc is fitted and adapted to slide. Also, this upper fish-plate rests against the 5o under side of the plow-beam 1, and is firmly secured thereto by the clips 29, which pass over the same and down through the preferably elongated openings 30, which are formed in the sides of said fish-plates, their lower ends being screw-threaded for receiving the nuts 3l, by which said plate may be tightened against, loosened for adjustment upon, or removed from said plow-beam. These adjustable fish-plates as constructed and the ad- 6o jacent parts not only afford a firm connection between the plow-beam and the furrow-wheel and its two-part jointed standard, but render it possible, by means of their adjustability, to apply them to plow-beams of varying sizes.

At the lower and upper ends, respectively, of

the two arms 17 and 19 of the furrow-wheel standard 1S is formed or provided an adjustable double connection or joint 32, which consists of the an nularly-arranged teeth or cogs 33 on the sides of the ends of the arms named, which engage each other and are clamped firmly togetherby the screw-bolt Btaud the nut The faces or sides of these cogs are preferably vertical and radiate from a common center, whereby, when engaged, they snugly intermesh and permit of no play or movement whatever, but by removing said nut and bolt they can be disconnected. Then the lower arm of the furrow-wheel standard can be moved into more or less vertical position, which, when its teeth or cogs are again engagedwith and secured to the opposite teeth or cogs, will have the effect of correspondingly raising or lowering the plow for forming shallow or deep furrows; also, by discounecting these cogs the lower arm of the furrow-wheel standard having the double set of annular cogs thereon can be transferred to the correspondingly-cogged opposite side-to the right or left-of the upper arm of said standard, and thereby effect the transposition of the furrow-wheel to the right or left of a line passing through the plow-standard or the point of the plow proper, as may be desired, 0r necessary in forming the furrowsin plowing. The lower end of the lower arm 19 of the f urrow-wheel standard is provided with a laterally-projecting axle 36, upon which the furrow-wheel is journaled. Also. at a point just above said wheel, this arm is provided with a laterally-projecting scraper 37, which readily removes all adhering dirt from the periphery of said wheel.

Having thus fully described the construction and arrangement or combination of the several parts of my invention, its advantages and operation, what I clain as new is- 1. In a plow, the combination, with abeam and a two-wheeled truck, of a single clipband formed with a vertical series of openings in its sides and secured upon said beam, two vertical arms pivoted to said truck at their lower ends and formed with a series of openings which register with those in said clip-band, an upper nutted screw-bolt passing through said beam and adjustably connecting said arms and clip-band, and a lower nutted screw-bolt passing through said registering openings and resting against the under side of said beam, substantially as and for the purpose described.
