SULKY-PLOW. 1

SPECIFICATION forming part of Letters Patent No..260,534, dated July 4, I882.

Applicatioufiled Febrnary18,1882. (Model) To all whom it may concern Be it known that 1, WILLIAM L. CASADAY,

of New Garlisle, in the county of St. Joseph and State of Indiana, have invented certain new and useful ImprovementsinSulky-Plows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to sulky-plows, the object being to'provide a plow of such construction that-the plow-point may be quickly and sists in theparts and combinations of parts hereinafter set forth, and pointed out in the claims.

In the drawings, Figure 1 represents a perspective view of a sulky-plow embodying my improvements. Fig. 2is a plan view of the same. Fig. 3 is aside elevation with wheels removed. Fig. 4 is a detached view of the plow-beam, partly in section, with its lockingbrace. Fig. 5 is a detached sectional view of the land-spindle and its sleeve mounted upon the axle-spindle. Fig. 6 is an enlarged detached view of the lifting-lever and crow-bill. Fig. 7 is a detached view illustrating the peculiar form of the plow-frame, and Fig. 8 illus trates the devices for securin g the rollingcolter to the plow.

A represents the frame of the plow,'one side of which forms a bearing, A1, and is provided with two parallel elongated slots, to, adapted to receive the axle B of the spindle of the furrow-wheel B, said axle being held in position by bolts 01. passing through slots in the axle and the slots at of the frame, and by nuts a A plate, 0., provided with perforations for the passage of the bolts a is interposed between the frame and the nuts a to hold the axleB firmly in connection with the frame. The

inner end of the axle B is cutaway or recessed and serrated on its front side, and adapted to engage with a serrated plate, 0. interposed between said inner end of the axle and the hearing A. The furrow-wheel B is mounted on the spindle B projecting from the axle B, and

is arranged at an angle to adapt it to run in sence of thelandside, which; in plows of the ordiu ary construction operates to overcome in great measure this tendency.

A more detailed description of the construciion and operation of the furrow-side-wheel and its connections is deemed unnecessary, since they constitute no part of the present invention, but are fully described and claimed in Letter Patent No. 246,598, granted to me Sep .5?

tember 6, 1881. l

The central part of the plow-frame consists of a. vertical guide-bar, 0, provided at its rear side with a rib,-c, adapted to fit within a corresponding groove, 0', formed in the rear vertical jaw, D, of the front section, E, of the plowbeam, while the front side, 0 of said guide-bar O is made plain to adapt it to bear against a correspondingly-plain edge of the front vertical jaw, D, of the front section of the plowbeam. a

Upon a stud, d, projecting outwardly from the jaw D, is journaled a roller, G, upon the opposite side of which the curved arms of the crow-bill H bear as the jaw D is raised and lowered.v

A lifting-lever, F, and the crow-bill H are made integral with or rigidly secured" to a sleeve or hub, G, which is journaled on a rod or hearing, G supported at one end by the guide-bar G and at its opposite end in a post, I. The lever F is provided at its upper extremity with a hand-lever, J, connected by a wire, K, or other suitable connection to a dog,

L, journaled in two lugs, l, projecting from the IcO The right-hand half of the sector N is pro-f vided with inclined teeth adaptedby their configuration to raise the dog L without manipulating the hand-lever J, and enabling the operator to lift the plow through a distance represented by half of the sector by simply pushing the lever F forward. However, in returning it to lower the plow, the dog L must be elevated. The left-hand half of the sector N is provided with an elongated slot, at, which admits of the attachment ofa segment, 0, provided with cog-teeth 0. The segment is held in place by a bolt, 0, passing through a slot, 0 of the segment and through the slot 12 of the sector, and provided with a nut, 0 By thus constructing the sector N of two parts a greater range of movement is given the liftinglever, and the depth of furrow can be better regulated, as the cogged segmentmay be adjusted relative to the sector by loosening the nut 0 E represents the front section of the plowbeam, and E the rear section of the same. The latter is provided with two perforated arms or cars, 0 between which is secured the rear perforated end, 0 of the front section, E, by gudgeon e passing through one of the ears, e, and the perforated end 6 of the front section, and a bolt, 6 provided at one end with a head, 6", andadapted to pass throughthe ears and the gudgeon and be held bya nut, 6. By this connection of the two plow-beam sections the rear section is allowed a full pivotal movement, and any wear of the parts may be compensated for by tightening the'nut c and thus preventing the rear section from lateral motion.

Within a recess, I, of the front section of the plow-beam is held the rear end of the tongue Q by bolts q and nuts g.

D D represent vertical jaws formed integral with the front section, E, of the plow-beam, and constructed, as above described, to slide on the guide-bar O of the plow-frame. The rear section, E, of the plow-beam is hollowed out or recessed, as shown, and provided with a slot, 6 to receive a plunger, R, pivoted to the lower end of the web d of the rear jaw, D, by a pivot, d. lhis plunger R extends rearwardly into the recessed portion of the section E of the plow-beam, and is provided with a lateral stud, o, projecting through the elongated slot 0 formed in the side of the section E.

A loop or catch, S, is formed upon or secured to the section E, adjacent to the slot 0 and said catch is adapted to engage a depending notched bar, T, pivoted at its upper end to a rearwardly-projectin g bracket, T, secured rigidly to one side of the guide-bar O of the frame.

U represents a bracket cast upon or secured to one side of the front end of the section E of the plow-beam. To this bracket U is pivoted a two-part locking-brace, U, the opposite end of the latter being provided with a depending lip, u, adapted to engage a catch, a, formed upon the front section, E, of the beam adjacent to the jaw D. Theforward end of this locking-brace is provided with two upwardly-projecting perforated lugs, 22, between which is pivoted by a pivot, 11, a lever, V, the rear end of which impinges against one end of a spring, 17 the opposite end of which is secured to the brace U. The lcverV is provided with a down waldlyprojecting lip, o adapted to bear against the forward end of the locking-brace U, and with the aid of the spring a to disengage said brace from the notch or catch u. A further object of the lever V is to weight the front end of the brace to assist the latter to engage with its catch a by gravity.

The brace U serves to hold the two sections of the beam in rigid connection, and it will be obvious that upon disengaging the brace from the catch u the rear section, E, to which the plow Z is connected, will fall, thus forcing the plow-point up from the soil.

In order to adapt the rear section, E, to different adjustments to vary the pitch or suction of the plow, 1 construct the locking-brace U in two parts, a: and ac. The rear and pivoted part, 00, consists of an interiorly-screwthreaded sleeve adapted to receive the screwthreaded end of the part 00. The latter is provided with a nut, x interiorly threaded and adapted to be turned to lengthen or shorten the brace U, and thus vary the pitch or suc' tion of the plow.

Y represents the drivers seat, secured by a suitable support to the seat-frame y, and so arranged relative to the brace U that the latter will be within easy reach of the driver.

The operation of the plow as thus far described is as follows: Suppose the plow to be in working position, as illustrated in Fig. 1, the two beam sections being held in rigid connection by the locking-brace U, and it becomes necessary to pass an obstruction. The driver will depress the lever V, which will at once disengage the brace U from its catch. The rear section, E, of the beam will then fall, thus tipping up the point of the plow, which will then pass over the obstruction. As the plow passes over the obstruction and the point begins to fall, the pendent notched bar T will engage with loop or catch S on the section E of the beam, and the beam and plow will be suspended by said bar, and as the beam resumes its working position the plunger It, by means of its stud 1', will disengage the notched bar from its catch S, the locking-brace U will fall and engage with its notch u, the plow being let down by the lifting-lever F. In the same way, when it is necessary to lift the plow out of the ground, the locking-brace is tripped, allowing the plow-point to tip up out of the ground, the notched bar T cngagin g the catch and holding the plow up until the lifting-lever engages its sector N and lifts the plow clear of the ground.

It is necessary that the dog of the lifting-lever should engage the first or lowest inclined tooth of the lifting-sector in order to utilize the automatic lift.

W represents a rolling colter, pivoted between the arms w byapivot-bolt, w. The

arms w are .providedat their point of union with a socket, 10 within which is pivotally secured the bent end 20 of a standard, w which latter is adapted to be clamped in any suitable manner to a bracket, 20 secured to the land-wheel side of the tongue. The colter W is adapted to extend under the lower brace, Y, of the frame. This brace is bent upwardly to form an arch, 3 This construction allows the colter to work freely without contact with the frame.

Upon the axle Y of the frame is mounted the sleeve A of the land'spindle B Said spindle and sleeve are arranged parallel, but diagonally oppositeeach other, and are connected by a curved brace, 0 made integral therewith. Thesleeve is held in position by a threaded bolt, a and a washer, to.

. Surrounding the outer end, of, of thesleeve A is a coil-spring, a, one end of which is secured to the sleeve, while the opposite end, a is bent, to adapt it to bear against the land-lever D". The latter is perforated at its lower end,to adapt it to fit the outer projecting end, 01 of the axle Y This lever D is provided at its outer end with a hand-lever, d connected by a wire, 01 to a dog, d", the latter being supported in perforated lugs d on the lever D and surrounded by a spiral spring, al the ends of which-respectively bear against said lugs. A bracket or shield, E projects, is secured to the upper side of the sleeve A and provided with stops 6 eflwhich limitthe movement of 'the land-lever, and thus protect the spring a from overstrain. A1and-sector,F is secured to the outer end of the axle Y in such position relative to the land-lever that the dog at of the latter may engage with the teeth of the sector to raise and lower thelandwheel.

The sector F is provided at a point adjacent to its pivotal point with a perforated lug, f, to which is secured one end of a brace, f, the opposite end of the latter being secured to the adjacent side of the tongue of the plow to firmly brace the parts together.

The land-wheel G is mounted on the spindle B which is screw-threaded to receive an interiorly-threaded retaining-cap, 9, suitable washers being interposed between the wheel and cap to insure free movement of the wheel and prevent undue friction.

i It will be apparent that many slight changes in the details of construction of my improvement may beresorted to without departing from the spirit of my invention. Hence I would have it understood that I do not limit myself to the exact construction shown and described, but reserve to myself the right to make such alterations of form and construction as may properly fall within the scope of my invention.
