Fig. 2 isaside eleindicated at 2 1, upon an extension of the vation thereof. Fig 3 is a plan view of the bracket 19 and connected, as by alink 25, with 45 implement organized for use as a single plow. the standard 20, the retention of the lever in Fig. 4 is a detail view on the linexm of Fig. 1. its adjusted positions being insured by a Like numerals are employed to designate spring-latch 26, associated with the lever and corresponding parts throughout the views. engaging a toothed segment 27, carried by the I0 hen organized for use as a gang-plow, as bracket. 5 shown in Figs. 1 and 2 of the drawings, the Against one side face of the rear extension implementincludesaplurality of interchange- 3 of each beam or element 1 is secured, by able frame-beams or disk-carrying elements 1 means of a bolt 28, a drop-bracket 29, carrying at its lower end a bearing-sleeve 30, disposed at an angle across the line of draft and designed for the reception of a disk spindle, the construction and arrangement of the bearing-sleeve, spindle, and disk being ordinary, and therefore requiring no further description. The bolts 28, which connect the beams and the disk-carrying brackets 29, also serve as retaining means for scraper-supporting yokes 31, each of which is bent over the edge of a disk and carries a scraper 32, by means of whiclx the disk is cleared. In addition to the functions recited the bolt 28, passing through the rear end of the last beam or element of the series or gang, serves also to retain what may be termed the rear furrowwheel bracket 33, in which is formed a ver tical journal-box 3a for the journal 35 of the crank-axle 36, upon the spindle 2 7 of which the rear furrow-wheel 38 is mounted. The rotatable mounting of the journal permits the axle 36 to swing laterally for the purpose of properly positioning the rear furrow-wheel with respect to the line of draft. it being observed in this connection that the several supporting devices of the plow are swiveled, since each of the several crank-axles is capable of a swinging movementdesigned to adjust the su p porting devices with relation to the frame. in addition to its lateral swinging movement the crank-axle 36 of the rear furrow-wheel, like the axle of the front furrow-wheel, is designed to be adjusted vertically relative to the frame. The journal 35 is therefore extended above the box 34 and is suitably con nected to an adjusting-lever 39, fulcrumed upon the wheel-bracket 33 and provided with a spring-latch an, engaging a toothed segment 11, carried by the bracket. The particular character of connection between the lever 39 and the journal 35 is not material; but this connection preferably includes a link 4E2, con nected at one end to the lever 39 and at its opposite end to a stud 43, projecting laterally from a ring 4 1, swiveled on the journal to permit independent rotary movement of the latter.

it has been premised that one of the objects of the present invention subordinate to the production of a readily-convertible plow is to provide means whereby a cooperative relation will be established between the draft appliance and the furrow-wheels to the end that said wheels will be properly positioned to facilitate the turning of the plow when the line of draft is changed. To this end associate with the crank-axle 36 an adjustable stop in the form of a swinging arm 45, extending, as shown in Fig. 2, from the lower end of a short rock-shaft a6, disposed verticall y and having a bearing in the bracket 33 adjacent to the journal-box 34 of the crank-axle. At its upper end the shaft &6 is provided with a crank-arm 47, connected, as by a connecting-rod 18, with the arm 16, the connection with the latter being effected at the side of the fulcrum 17 opposite to the mounting of the front furrow-wheel 22. The inner end of the arm 16 is in turn connected by a link 19 with a bell-crank lever 50, connected at its opposite end to the draft appliance-as, for instance, the swingletree 51. The bell-crank lever 50 is adjustably fulcrumed upon a clevis 52, carried at the front end of what may be termed the draw-bar 53, disposed longitudinally of the plow and guided by the yoke 9. The rear end of the draw-bar 53 is deflected upwardly, as shown in Fig. 2, and is adjustably connected to the upper end of a frame-depressing bar 541, extended below the rear end of the front beam 1 and connected thereto, as by a link 55. This arrangement of the draw-bar and the frame-depressing bar constitutes a siniple appliance for converting the pull exerted by the d raft-animal into a downward pressure upon the rear end of a beam or disk-carrying element, it being observed that the pull upon the front end of the draw-bar will cause the upwardly-curved portion of said bar to engage the upper end of the yoke 9. which acts as a fulcrum for the bar. Therefore the pull on the bar tends to depress its rear end and to thus depress the frame through the intermediate connection to insure such penetration of the ground as is necessary to secure the proper cut or depth of furrow. It will also appear that when the line of draft is changed as, for instance, in making a turn to the right-the bell-crank lever will be swung to the position. indicated in dotted lines in Fig. :1, the connection between said lever and the arm 16 swinging the front furrowwheel to the position indicated in dotted lines and withdrawing the stop-arm 15 from engagement with the crank-axle 36 to permit the rear furrow-wheel 38 to assume a position substantially at right angles to the front furrow-wheel 22. With the wheels thus disposed it is clear that a sharp or square corner may be turned and one of the objects of the invention thus attained.

llf with the parts in the positions indicated in full lines in Fig. 1 a turn is made to the left, the front furrow-wheel will obviously be turned to an angular position the reverse of that shown in dotted lines in Fig. 1, and as the inner end of the arm 16 moves rearwardly the crank-arm L7 will be swung in a similar direction, and the arm a5, which normally constitutes a stop element, will then become an actuator, serving to positively swing the crank-axle 36 to lispose the rear furrowwheel at a reverse angle. In this event the plow will turn toward the land with the landwheel 1 1 as an axis, and the front and rear furrow-wheels will be positioned to follow around in arcuate paths without material side draft, thus permitting in this direction, as in the other. a sharp turn without excessive strain on either the implement or the draftanimal.

The vertical adjustment of the land-wheel 14 with respect to the frame of the plow is effected by a lever 56, arranged to swing the axle 13 vertically, and provided with a springlatch 57, engaging a toothed segment 58 at one end of the journal-box 11.

If it is desired to employ the implement as a walking-plow, handles 59 may be secured to a bracket 60, connected to the extension 8 of the rearmost beam, as by the bolt 28, as shown in Fig. 1, or, if desired, the implement may be used as a riding-plow by attaching a seat to the beam in lieu of the handles.

In Fig. 3 I have shown the implement converted for use as a single plow, the change having been effected by detaching the rear beam and by securing the wheel-bracket 33 and its complementary parts, together with the handle-bracket 60, to the rear end of the front beam. This conversion is thus seen to be accomplished without the introduction of any new or additional elements except, perhaps, a shorter connecting-rod 48. WVith equal facility the number of units of the plow may be increased by detaching the handlebracket 60 and the wheel-bracket 33 from the second beam and by reattaching these elements to another beam secured to the second beam as the latter is secured to the first or foremost beam.

It is thought that from the foregoing the construction, operation, and many advantages of my plow will be clearly comprehended; but while the illustrated embodiments of the invention are thought at this time to be preferable I do not limit myself to the structural details defined, as, on the contrary, I reserve the right to effect such changes, modifications, and variations of the illustrated structure as may fall fairly within the scope of the protection prayed.
