SPECIFICATION forming' part of Letters Patent No. 726,709, dated April 28, 1903. Application filed September 23, 1902. "serial No. 124,509. (No model.)

To all whom it may concern.-

My invention relates to improvements in ditching-plows; and one object that I have in view is the productionof asimple and efficient machine adapted to perform the work of clearing weeds and otherobstructions from both field and head laterals of irrigating"- ditches and for making newirrigating-ditches.

A further object of theinvention is to equip a ditching-plow with an improved form of landside which is especially designed to overcome ahy tendency of the landside to run upward against a side of the ditch, and thereby obviate rocking or side flopping of the plow when equipped with an ordinary con.- tinuous landside. v

A further object is to provide improved means for bodily raising the plow and adapted to support the same in an elevated posi-.

tion clear of the ground in order to easily transport the apparatus from one place to another or to turn the plowaround, one of the supporting devices being 'regnlatable to vary the depth of the plow-point.

A further objectjs to provide means whereby the width of the machine may be'varied to adapt it for service in ditches of varying widths. I

A further object is to provide means under control ofthe operator to adjust the rear part of the machine for use in ditches'of deep or shallow depths.

A further object is to provide meanswhereby the rear axle may be rocked, extended;

and shifted "bothlaterally and angular-1y in order to maintain it ina level position and at right angles to the landside under all conditions or' adjustments of the machine or its several parts, thus making the axle run freely and easily in its boxes and overcoming one of the serious objections to machines of this type, in which the axle is liable to bind and run unevenly in its bearings.

Further objects and advantages of invention will appear from the subjoined description, and the novelty will be defined by the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of a ditching-plow constructed in accordance with my invention. Fig. 2 is a side elevation thereof, certain parts being broken away. Fig. 3 is an enlarged sectional elevation taken in the plane of the dotted line 3 3 of Fig. 1. Fig. 4 is a section atright angles to Fig. 3, taken in the plane of the dotted lines 4 4 of Fig. 3. Fig. 5 is a detail transverse section through a portion of the moldboard. Fig. 6 is a detail horizontal section through the front landside-bar, the point, and a part of the moldboard; and Fig. 7' is a detail sectional view of the means for supporting the front casterwheel. Fig.8 isa detail view showing the parts comprising the extensible brace between the moldboard and one member of the dividedl'and'side.

5 designates a draft-beam which is similar to the beams'used on ordinary plows, except that the arch and the draft end thereof are somewhat higher than the ordinary beams in order to secure the proper draft on the implement andto allow ample room for trash which aboundsmore or less in old irrigationditches which it may be desired to clean out. The front'end of this beam is provided with a vertical'elongated clevis 6, having a vertical series of apertures of any suitable number, thus "making provision for the attachment of the draft appliance in a manner to suit the number of horses that may be employed in hauling the machine through a ditch. l

To the rear lower endof the draft-beam is bolted a landside-supporting bar 7, the same consisting of a flat plate which is:fastened at a point intermediate of its length to the beam.

The landside which I-em ploy consists of two supporting-bar 8, the latter being located at the rear end of the machine.

The front member of the landside is indicated at 9 and the rear landside member at 10. These two members are fastened securely to the supporting-bars 7 8, respectively, such fastening of the parts being attained by the employment of a bolt orother suitable means. The landside member 9 is a flat plate applied laterally to the bar 7and presenting an edge to the ground. The landside member 10 is applied and arranged in a similar way with relation to the bar 8; but the rear member 10 is somewhat wider than the front member 9, the lower edge of said wide member 10 being curved or deflected laterally, so as to prod nce a rib or [in 11,which is adapted to ride against one of the walls of the ditch.

It will be observed that the landside is interrupted or discontinuous owing to the spacing of its members at some distance apart, as shown by the drawings, and this discontinuons construction of the landside in connection with the outwardly-trending rib or fin 11 on the rear member overcomes sidewise movement of the implement, this sidewise movement of the implement being one of the objectionable features of ordinary ditching plows having continuous landsides.

12 designates a moldboard which extends lengthwise of the machine,said moldboard being disposed in an oblique or inclined position relative to the plane of the landside and also occupying an outwardly and rearwardly inclined position, as clearly shown by Figs. 1 and 2 of the drawings. This landside has aconcave working face 13, and the rear corner of this moldboard at the lower part of the raised rear end thereof is curved upward slightly, as indicated at 14, thereby giving a twisted contour to the rear part of the moldboard, which enables it to slightly raise the soil as it travels thereover. The moldboard is supported by and attached to a frame which consists of a pair of angle-bars 15 16, which are disposed parallel to each other and arranged within the machine to correspond to the position of the inclined moldboard. These parallel supporting-bars are on the rear side or convex face of the moldboard, and the front ends of the bars are extended or prolonged beyond the lower end of said moldboard, thus making provision for the attachment of a hinge-plate 17. This hinge-plate is disposed between the parallel bars and to one side of the plane of the moldboard, and said hinge-plate extends forwardly beyond the front end of said moldboard. The hingeplate is adapted to meet with the front end of the landside-supporting bar 7, and said plate and the bar are united pivotally or hingedly together, as at 18, thus making provision for the lateral or angular adjustment of the moldboard with relation to the front landside member. Any suitable orpreferred construction of hinge-joint may be adopted, 1 and the front landside 9 and the front portion of the moldboard are united by an extensible brace 19, the same consisting, preferably, of parts which are attached to the bar 7 and to the bars 15 16, said parts of the brace overlapping each other and fastened together in a manner to permit endwise adjustment of said brace.

20 designates a point which is disposed in advance of the moldboard 12 and lies flush therewith. The point is provided with inclined side edges which converge toward the front penetrating end of said point, the latter being beveled or tapered so as to easily clear its way through obstructions or to penetrate the soil of the ditch. The tapering point at its rear end is equal in width to the front part of the moldboard, and said point is adapted to be secured firmly to the extended front ends of the parallel angle-bars My invention contemplates the employment of interchangeable points, and the point which is used for cutting the soil in a manner to form a new irrigation-ditch is quite short, so that its front end will lie flush with the front landside member 9, as shown by Fig. 1. The point may, however,

be modified so as to increase its length, es-

pecially when the machine is employed for cleaning out old irrigation-ditches by removing the growth of weeds or other obstructions therein. The long point which maybe used is intended to be fastened to the frame formed, by the angle-bars 15 16, so as to 00- cupy a flush relation to the moldboard 12, and the active end of this long point is adapted to extend beyond the front landside member 9. 4

The rear ends of the angle-bars 15 16 are extended or prolonged beyond the rear end of the moldboard 12, and the angle-bars support an arm 21, the same lying at right angles to said bars at their ends. (See Figs. 2 and S.) The arm 21 is of channeled form to receive the member 22 of the extensible brace, and this brace lies at an angle to the bars 15 16, which support the moldboard. A bar 22 is arranged between the arms 21 of the anglebars, and one end of this bar is bolted or otherwise fastened in a secure manner to the rear bar 8, which supports the landside member 10. The arms 21 and the bar 22 form an extension-brace between the supporting-bar 8 and the angle-bars 15 16, and the member 22 of this extension-brace is fastened adjustably by the bolts 23 to the arms 21, which constitute the other member of the extensible brace, whereby the parts of the machine at the rear end thereof are connected firmly together, and provision is made for adjusting the moldboard and its supporting-bars to different angular position with relation to the divided landside, whereby the width of the machine may be varied to enable it to work advantageously in ditches of different widths. The rear part of the plow-beam 5 and the front part of the rear supporting-bar 8 are I hanger 47.

connected by a draft brace or rod 24, the end portions of which are rigidly fastened to said beam, and the front supporting-bar 7 is braced by a stay 25, having its upper rear end attached to the brace 24.

26 designates a caster-wheel which is journaled in the lower end of a forked hanger 27, the latter having a vertical stem 28, which is swiveled in a carrying-block 29. This carrying block is rigidly fastened to a pair of hanger-arms 30, and these hanger-arms are pivoted, as at 3l,to the front end of the four links 32, the latter being disposed in horizontal positions. One pair ofhorizontal links are pivoted at their rear ends to the upper ends of the vertical supporting-arms 33, the latter being fastened rigidly to the plow-beam 5 at a point intermediate of its length, and

the other pair of these horizontal links are pivoted to the lower ends of the vertical arms 33, the pivotal connections of the links 32 to the vertical fixed bars being indicated at 34.

35 designates a bell-crank lever which is fulcrumed at its angle or corner on a'transverse bolt 36, attached to the forward ends of the upper links 32 and the upper ends of the hanger-arms 30, and one end of this bellcrank lever is attached by a rod or chain 37 to the front part of the plow-beam, preferably at a point in rear of the clevis 6 thereof. The other arm of the bell-crank lever 35 is fastened to a rod 38, which extends rearwardly from the beam 5 and is fastened to the upper end of a lever 40, that is fulcrumed on the draftbar 24, and from this lever 40- extends another rod 41, which is attached to an adjusting-lever 42, the latter being located at the rear end of the machine and on the outside face of the rear landside member 10.- This lever 42 is rigidly fastened to a short shaft 43, which extends through a landside member 10, the supporting-bar 8, and the rear part of the draft-bar 24, so that the'inner end of this short shaft 43 terminates on the inside of the machine, thusmaking provision for the attachment of a treadle-lever 44 to said shaft. This treadle-lever 44 is provided with a short arm 45, to which is attached a link 46, the latter being fastened to the lower end of a bell-crank wheel- Said wheel-hanger is pivoted or fulcrumed at 48 to the landside-supporting bar 8, and in the other arm of this wheel-hanger is journaled a carrying-wheel 49, the same being normally held by the wheel hanger in a position raised above the lower outwardly-turned edge 11 of the landside member 10. The adjusting-lever 42 may be provided with a thumb-latch 42, adapted to engage with a segment 42", provided on the landside, as indicated in Fig. 4. The lever 42 and the treadle-lever 44 are arranged within convenient reach of a driver adapted to' 44 in order to simultaneouslyadjust the casterwheel 26 and the carrying-wheel 49. It is evident that the wheels 26 49 may be depressed for the purpose of raising the plow out of the ground, and the plow may be sustained in a raisedposition for the purpose of conveniently transporting the machine from one place to another or for turning the machine around. The lever 42 may also be adjusted to lower the caster-wheel 26 a limited distance, and thereby make said caster-wheel regulate the penetration of the point 20 into the soil.

51 designates an axle having an extension member 52. The member 51 is provided with a polygonal or square socket in which is slidably received the angular or polygonal axle member 52, thus making provision for endwise adjustment of the-axle when the moldboard is adjusted to different inclined positions relative to the landside for the purpose of increasing or decreasing the width of the machine. The axle member 51 is journaled in an axle-box 53, which is supported between the parallel angle-bars 15 16 at a point just in rear of the moldboard 12, and the outer end of this axle member 51, is provided with a crank 54, to which is attached a stub-axle 55, adapt-ed to carry a ground-wheel 56. The member 52 of the extension-axle is connected with the socketed member 51, so as to rock or turn therewith and at the same time be capable of a slidable movement relative thereto, and this axle member 52 is journaled in a bearing-opening 57 in a vertically-movable slide 58. This slide 58 is disposed within a vertical frame-plate 59, the latter being mounted on a horizontal guide-rail 60, which is secured firmly to the draft-bar 24 or to the rear-landside-supporting bar 8. The frameplate 59 is adjustable horizontally on the rail 60, and to operatively connect said frameplate and the rail in a manner to permit this horizontal adjustment of the frame-plate I employ a slidable connection between the parts. The rail 60 is provided with grooves in its side faces adapted to form a T-head 61 at the upper edge of said rail, and the lower part of the frame-plate 59 is constructed with a flanged shoe 62, the latter being arranged to embrace the T-head of the rail 60, while the flanges of said shoe are received in the grooves of the rail, reference being had more particularly to Figs. 3 and 4.

The frame-plate 59 is provided at its front and rear edges with the vertical guideways 63, in which are fitted the front and rear edges of the vertically-movable'slide 58,'which serves as a bearing for the axle member 52, and this frame-plate 59 is furthermore provided with a toothed rack 64, the same being disposed in a vertical'position at the rear edge of the plate and in rear ofone of the guideways 63 thereof. The vertically-movable slide 58 is provided with a horizontal arm 65, the same extending-outwardly from the plate at the lower edge thereof and supporting a vertical rack-plate 66, the upper edge of which is formed with a series of notches, forming a rack 67. The rack-plate is joined by the arm with the slide 58, which supports the axle member 52, and this rackplate 66 is disposed in a lateral spaced relation to the shaft-slide 58. The parts practically constitute a single casting. The shaftslide 58 and the rack-plate 66 are spaced far enough apart to accommodate two levers 69 70, said lever 69 being somewhat shorter than the lever 70, as shown by Fig. 4E.

The short lever 69 is fastened rigidly to a gear pinion 71, having a round opening adapted to fit on the polygonal axle member 52 for the purpose of making said pinion and the short lever 69 loose on the axle, and this gear-pinion 71 has intermeshing engagement with the rack 66 of the vertical frame-plate 59. The lever 69 is adapted to turn the pinion 71, which meshes with said stationary rack (it for the purpose of raising the inner end of the axle and slide 58, in which the axle member 52 is journaled, thus making provision for leveling the axle under certain conditions in the service of the machine.

The long lever is provided with a rack 72, with which engages a latch 73, that is carried by the lever 69, and this lever 70 is provided with a foot-piece 74, having a square opening to receive the square axle member 52, thus making the lever 70 fast with said axle. Said lever 70 is furthermore provided wit-h a latch 75, which is adapted to engage with the rack 67 on the plate 66, that is attached to or forms a part of the shaft-slide 58, and this lever 70 is adapted to rock or turn the axle formed by the members 51 52 in a manner to adjust the crank 54 and the ground-wheel 56.

The parts of my improved machine are intended to be constructed of iron and steel; but any suitable materials may be adopted in the manufacture of the machine. The improved means for adjusting the extensible axle 51 52 enables the axle to be kept in a level condition under all adjustments of the various parts of the machine to suit ditches which may vary in width and depth and at the same time allows the axle to be brought under all conditions of service in a position at right angles to the plane of the landside, thus preventing the axle from being thrown out of line, cutting the axle-boxes 53 58, and overcoming any tendency of the machine to run untrue.

The lever 70 is adapted to adjust the crankaxle in a way to secure two objects first, to

raise and lower the rear part of the moldboard, so as to throw the dirt into any depression that exists in the ditch-bank, and secondly, to overcome inequalities of the ground over which the wheel 56'is compelled to travel, such as back furrows, dead-furrows, ant-hills, &c. When the machine is in operation in a deep ditch, the angle of inclination of the axle 51 52 to the landside is greater than when the machine is in a shallow ditch, and to keep the axle in a level position and allow the desired movement of the parts the lever 69 may be adjusted to make the gearpinion 71 raise or lower the shaft-slide 58 relative to the upright frame 59. When the moldboard is adjusted to change the angle relative to the landside, and thereby widen the rear end of the machine for large ditches, the angle of the axle 51 52 is changed with relation to the plane of the landside; but by moving the shoe 62 and the frame-plate 59 on the T-head of the horizontal rail 60 the axles and the parts cooperating therewith may be brought into proper position relative to the landside, so that the axles will lie at right angles thereto.

From the foregoing description, taken in connection with the drawings, it is evident that the lever 69 is employed to adjust the divided axle for leveling the same, while the lever 70 is adapted for operation in a manner to rock or turn the axle in order to raise or lower the ground-wheel 56. When the shaft is in a proper leveled condition and the latch 73 of the lever 69 is engaged with segment or rack 72 of the lever 70, any movement of the large lever 70 to raise or lower the heel of the moldboard must raise or lower the inner end of the axle correspondingly, whereby the axle is kept level and the wheel is maintained in line with or parallel to the machine.
