'WHEEL-PLOW.

SPECIFICATION forming part of Ltfers Patent No. 614,343, dated November 15, ieee.

Application filed October 26, 1896. Serial No. 610,139. (No model.)

To all whom, it' 11i/ty concern:

Be it known that I, STALEY D. POOLE, a citizen of the United States, residing at Moline, in

` the county of Rock Island and State of lilinois, have invented certain new and useful Improvements in Wheel-Flows; 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 appertains t0 make and use the same.

This inventionrelates to wheel-plows, but more particularly to riding, sulky, and gang plows, and aims to provide a simple and efficient mechanism for locking the plows in the ground, so as to securely hold them to their work, yet permitting, if desired, the adjustment of the locking mechanism so as to allow the plows to yield sufiiciently to prevent injury while plowing stony ground, to combine with said locking means means by which the plows may be readily and easily raised to a sufficient height above the ground, to provide automatic means independently of said lifting means adapted to hold the plows in a raised position, and to provide simple and eflicient automatically-actuated locking mechanism to prevent or allow the rear furrow-wheel to oscillate or move laterally.

With these and other objects in View the invention consists in the construction and combination of the several parts, substantially as hereinafter described and then pointed out in the claims at the end of the description.

' Referring to the accompanying drawings, forming a part of this specification, Figure l is a perspective view of a sulky-plow embodying my invention, the plow-beam being in a raised position, this view and also Fig. 2 being on a larger scale than the remaining figures. Fig. 2 is a perspective view of the plow, looking from the side opposite that shown in Fig. l, the plow-beam being lowered. Fig. 3

is a fragmentary plan view.. Fig. 4t is a fragmentary perspective view illustrating means for raising the plow-frame on the front-furrow-wheel axle. Fig. 5 represents detail views of the tongue-arm and several of the elements shown in Fig. 4. Fig. 6 is a side elevation of a fragmentary portion of the front-furrowwheel axle and bracket and the unlocking mechanism for the rear furrow-Wheel. Fig. 7 represents detail views of the bracket, lifting-lever crank, and crank connections of the lifting and locking mechanism for the plowbeams. Fig. 8 is a detail perspective view of the rear-furrow-wheel lock-plate, together with a spring-latch, which coacts with it, and a portion of the frame of the plow. Fig. 9 is a detail side elevation of the land-wheel axle and collar. Fig. l0 is a detail view o'f the plunger-rod for the land-wheel. Fig. ll is a detail perspective. view of the latch for holding the plow-beam elevated. Fig. l2 is a fragmentary side elevation of a slightly-modied form of locking and lifting mechanism for the plow beam or beams, illustrating one meansv for preventing Said mechanism assum ing a dead-center while plowing stony ground. Fig. 13 represents a plan view of a modified form of locking mechanism for the rear furrow-wheel. Fig. 14 is a perspective view of a gang-plow embodying my invention; and Fig. 15 is a longitudinal vertical section through the frame of the gang-plow, the lifting-lever and break-joint connection being removed.

In the drawings,A may designate the frame, which is preferably made by bending a metallie bar or band into rectangular form and may be supported above the ground by the land-wheel B, the front furrow-wheel C, and the rear furrow-wheel D, all of which may be of the usual or of any preferred construction. The land-wheel has its axle b provided with an offset forming two substantially parallel bearing end portions, on one of which the land-wheel is held to rotate and the other of which is arranged so as to oscillate in a bearing or bracket b, which is secured to and proj eets outwardly from the side of the frame A, a collar b2, Fig. l, being secured to the shaft and arranged in a recess formed intermediate the ends of said bracket, so as toprevent lateral movement of the axle and to retain the same within said bracket. This bracket has a segment b3 secured to its outer end by a bolt or otherwise, to which is pivoted a lever b4, having a detent or catch of any preferred form for engaging the teeth of IOO the segment so as to retain the lever in various adjustments. A preferably curved rod b5, Figs. 10 and 14, has one end pivoted to the land-wheel lever intermediate the ends thereof and its other end passed through an aperture in a projection on the collar 176, so as to be guided therein when said lever is raised 0r lowered, said rod having a spring 57 around the same and interposed between its upper end and the projection on the collar b, so that the land-wheel may be yieldingly held to the ground to permit said wheel to pass over obstructions.

The frame A may have pendent brackets d and cl secured to the fore and rear portions and on opposite sides thereof, so as to be opposed to each other, in which the outer ends of the beam-bails d2 and cls, respectively, are journaled, said brackets being provided with apertures for the ends of the bails and preferably with flanges at their upper ends adapted to embrace the upper and lower edges of the frame, so that by passing a bolt, as shown, through the brackets and the frame said brackets will be rigidly held in position. The bail d2 may be substantially V-shaped and the bail d3 substantially U-shaped, both of which have their central portions journaled in boxes d4 and d5, which are secured to the fore and rear portions, respectively, of the plow-beam D. These boxes may be of any desired form and construction, the box d4 being preferably narrower than box d5 and preferably comprises two members, one of which forms the upper bearing-surface for the bail d2 and the other the lower bearing-surface therefor, said lower member having its lower portion bifurcated, so as to embrace the sides and be secured to the plow-beam, while the box d5 preferably comprises three members, one of which forms the upper bearing-surface `for the bail cl3 and the other members, which are secured on opposite sides of the beam, form the under bearing-surface for said latter bail. A clevis d6 of any desired form may be secured to the plow-beam instead of to the frame in order that the strain may be removed therefrom, the beam and bails being preferably arranged so as to swing forward and downward while lowering the plows and rearward and upward while raising the same. By this means the pull of the horses will assist in lowering the plow or plows and the lifting be made more easy by reason of the plow being forced rearward and upward out of the hole made by the point thereof instead of being forced or lifted through the ground.

As an automatic means forholding the plowbeam elevated and for permitting said beam to lower without manipulation of hand-levers I preferably pivotally secure to the beam a latch e, Figs. 1, 3, and 1l, provided with an upright or projecting portion e' and a hooked or toothed end e2, adapted to engage the hooked end of acatch-rod c3, the latter having one end pivoted to the frame or a bracket secured thereto and its other end passed between the' two lower members of the box d5, so as to rest on the upper edge of the beam and in the path of movement of the latch. The latch e is preferably normally pressed rearward by a suitable spring, as at e4, and has its hooked end arranged so as to automatically engage the hooked end of the catch-rod e3 when the beam is raised a sufficient height above the ground, so that the operator while in the seat E may, by kicking or pressing upon the upright portion c of the latch with his foot, unlock the plow-beam, which will permit the plow to plunge forward to the required depth, assisted by the pull of the horses, in which position it may be rigidly held by the locking mechanism F. This mechanism preferably consists of a strap f, Figs. 1, 7, and 14, which has one end pivoted to a bracket or connection f', secured to the side of the plow-beam, and has its body portion pivoted to an arm f2 of a crank fa and may have its outer end notched, so as to engage a projection or stop f4 on said arm in order to form a knuckle or break-joint connection between the crank and said beam and to provide a lock by reason of the arm and strap being in substantially the same plane or on a deadcenter when the plow or plows are lowered. The crank f3 has its shaft journaled in abraoket or bearingf5, which is provided with a bifurcated lower portion adapted to embrace va portion of the frame and has its outer end secured to a lifting-lever f6, so that by forcing or drawing said lever rearward the joint will be broken and the plow and beam raised by means of the crankarm and strap, a springf7, Fig. 3, being secured to a portion of the beam (in this instance a hook and foot-rest f8) and its other end to the frame, so as to assist in lifting the plow and beam by the power stored therein `while the plow is being lowered. The strap f may be made without the notched upper end, Fig. 12, and the projection or stopflpreferably provided with a set-screw f9 or other device adapted to be adjusted so as to abut against a projection f 10 on the bracket f5 to prevent the crankarm and the strap f assu ming a dead-center or locked position while plowing stony ground in order to avoid break ing or injuring the mechanism, or the setscrew may be arranged in the projection f1" so as to abut against the under side of the crank-arm f2' It will thus be seen that simple and efcient means are provided for lowering the plow or plows without the manipulation of hand-levers and the plow or plows properly held to their work and readily raised and held in an elevated position at a considerable height above the ground.

The front furrow-wheel C is preferably of the staggered type and is adjustably held upon the lower or angular end of the axle g by means of the collars g' and g2, located on opposite sides of the hub portion thereof. The

vertical portion of the axle is journaled in IOO IIO

IZO

the bracket g3, secured to a side bar of the frame by bolts passing through portions thereof or otherwise and has its body portion passed through apertures in the angular or bent ends of a support g4, said support having its body portion arranged on the side of the frame-bar opposite the bracket g3 and its bent or angular ends located above and below said bracket. This support g4 is prevented from vertical movement upon the axle g by means of the collar g5, secured to the axle, preferably adjustably, beneath the lower bent end of the support and the tongue-arm g, which is secured to the upper end of the axle. The tongue-arm has the tongue-casting g? secured thereto, to which the tongue is secured, so that when the tongue is moved laterally the axle g will be rotated in its bearing. At the inner side and upper portion of the support is secured a segment or rack g8, to whichvis pivoted a lever 99, having the usual or any preferred form of ratchet mechanism for holding the lever in various adjustments. This lever has its end bent at an angle and connected by the lever-strap gw to the frame, so that by moving the lever upon its pivot the frame and bracket g3 may be raised or lowered upon the axle g. By means of the front furrow-wheel lever gil and the landwheel lever b4 the plow or plows are adjusted so as to run level and cut the furrow the proper depth.

For the purpose of holding the rear-furrowwheel axle stationary or to permit the wheel to move laterally either freely or when the tongue is shifted to one side I provide the axle h with an offset and an angular portion, so as to incline the wheel D or cause it to be staggered and have its body or vertical portion journaled in a bracket or bearing h', secured to the rear of the frame A, and its-upper end provided with a lock-plate h2, having a recess or notch adapted to be engaged by a tooth h3, projecting outwardly from a springlatch h4. This latch has one end secured to the frame or a separate bracket thereon or to a projecting portion of the pendent bracket CZ on the left side of the frame and has its free end connected by a rod h5 to a sliding plate h6, Figs. 2 to 6, inclusive, arranged to slide upon the upper portion of the bracket g3. The sliding plate is provided with an elongated slot or opening, so as to fit over the upper end of the bracket g3, and with a slot extending longitudinally of the plate and fitting over a projection k7 on the bracket g3, so as to be guided thereon, and has an upwardlyprojecting portion or end adapted to be engaged by projections or lugs hs, carried by the collar hg, said collar being slidingly held on the axle g by a key and groove or otherwise, so as to engage the projecting end of the sliding plate h6 and force the same forward when the axle is rotated in either direction by the lateral shifting of the tongue andtongue-arm in order to releasethe tooth of the springlatch h4 from the recess in the lock-plate h2 ward and down filling the front end of the recess and preventing the entrance of the tooth on the spring-latch t'hereinto, so as to permit the axle of the wheel D to oscillate freely at all times. Thus it will be seen that the rear furrow-wheel may be readily held in the same plane as the machine or permitted to shift laterally at all times or only when the tongue is moved so as to turn the machine to either side.

The construction and operation of the invention will be readily understood from the foregoing description when taken in connection with the accompanying drawings. suming the plow to be adjusted to cut at the required depth by means of the land-wheel lever b4 and the front-furrow-wheel lever Q9, which latter lowers or raises the frame and bracket g3 upon the axle g, and the parts to be in the position shown in Fig. l, it will be seen if the operator releases the catch e by pressure of the foot upon the projecting portion e thereof or otherwise the plow will plunge downward and forward the required distance, assisted by the pull of the horses upon the beam. This lowering of the plowbeam will place the strap f and the crankarm f2 of the locking mechanism F in the same plane or on a dead-center, so as to rigidly hold the plow or plows to their work, or said crank-arm and strap may be held slightly off the dead-center or otherwise by adjusting the set-screw j in order to permit the plows to raise or yield sufficiently to prevent break- IOO ing or injuring parts of the machine while plowing stony ground. The tooth of the spring-latch being in engagement with the recess in the lock-plate h2 upon the tongue being shifted laterally in either direction while makinga turn or for other purposes, the tongue arm g, which is connected to the tongue and the front-furrow-wheel axle g, will rotate the latter in its bearing in the saine direction as the tongue is shifted. The rotation of the axle also rotates the collar hg, which causes one of its projections or lugs hs to engage the upwardly-projecting portion of the sliding plate h6 and forces the same and the rod h5 forward, releasing the tooth of the latch h4 from the plate h2, thus permitting the axis of the rear f urrow-wheel to oscillate or rotate freely in the bearing h. When the tongue assumes a substantially parallel position relatively to the plane of the frame, the recoil of the latch will cause the tooth thereof to assume aposition for engagement with the lock-plate to hold the axle h stationary until the tongue is again shifted laterally. Should the operator wish to raise the plow, the lever f6 may be drawn rearward, which will break the knuckle or locked joint formed IIS t i (si-1,3491

by the crank-arm f2 and strap fand by means of said strap and arm will raise the beam rearward out of the ground to the desired height, the recoil of the spring f7 assisting in such raising. As the plow-beam reaches the proper height the hooked or toothed end of the spring-pressed catch c will automatically engage the hooked end of the catch-rod e3 and rigidly hold the beam and plow in an elevated position.

I thus provide a simple, strong, and efficient wheel-plow which dispenses with the use of levers for lowering the plow or the handling of levers after the first furrow is opened and the plows adjusted to run level and at the desired depth, which may be readily raised to the desired height and automatically held in an elevated postion, and which has its rear furrow-wheel automatically controlled from the forward portion of the machine.

In Figs. 14 and l5 the construction and the operation of the parts are substantially the same as in the sulky-plow. I-Iere two plowbeams are shown connected to the hails, so as to be simultaneously raised or lowered, said bails being somewhat wider than the bails in Figs. l and 2. Each beam is preferably provided with separate bail-boxes connecting it to the front and rear bails, though of course the form of the bails and the manner of connecting them to the plow beam or beams may be changed to meet different requirements. At t' is a latch-arm pivoted bya clip or otherwise to the rear beam-bail, so as to be raised or lowered thereon, and has a projecting portion t', adapted to be engaged by the notched end of a catch-rod i2. This rodis preferably pivoted at one end to the lower portion of a bracket t3, which is secured to the frame, and has its upper end pivoted to the latch-arm t', so that when the plow-beams are raised, as

e shown, said arm and catch-rod will be in substantially the same plane, so as to form a dead-center with respect to the downward movement of the beams, and when the arm is tilted by the foot of the operator or otherwise to throw the forward end upward the joint will be broken and the plows permitted to lower.

I preferably em ploy the mechanism shown in Fig. 13 for holding the rear furrow-wheel of the gang-plow stationary or to permit the same to oscillate freely in its bearing, though in some instances this mechanism as well as the automatic mechanism for holding the plow-beams elevated may be employed on a sulky-plow. The lock-plate 7o is preferably arranged substantially parallel with the rear bar of `the frame, and has its outer end provided with a notch adapted to be engaged by the tooth of a bell-crank lever or latch lc. This lever may be pivoted to the frame or a bracket secured thereto, and has one arm thereof connected to the rod h5 in a manner similar to that shown in Fig. 3, and has its toothed end normally pressed inward by a suitable spring, as at 7a2, so that when the rod h5 is operated, as heretofore explained, the toothed end of said lever will be disengaged from the plate 7:; to permit the axle to oscillate freely in its bearing and when released will again engage said plate through the action of the spring.

The plow beam or beams may each have a colter-shank In secured thereto in advance of the plow, to the lower end of which may be secured the yoke m', having a rotary colter m2 journaled therein.

It is obvious that in the use of the words beam7 or beams either is intended, according to whether the mechanism is employed on a sulky, gang, or other plow, that some of the parts may be used in other connections than with plows or that some of the parts may be changed-as, for instance, the crank-arm f 2 of the lifting and locking mechanism may be secured directly to or formed integrally with the lever f6-and that some of the parts may be dispensed with or others substituted therefor without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

l. The combination of a wheeled supporting-frame, a plow-beam lnovably connected therewith to permit its being raised and lowered with relation thereto, means for lifting the plow-beam, and automatioally-operating devices for sustaining the plow-beam in its elevated position independently of said lifting means and adapted to be independently released to permit the lowering of the plowbeam without manipulation of the lifting means.
