:orrrcnnve Ann nvnn-iininmne APPARATUS.

To all whom it may concern:

' "Be it known that I, OsoAR W. SnrrH, a citizen of the United States and resident of Carlisle, Lonoke County, Arkansas, have invented a certain new and useful Improvement in Ditching and Levee-Buildingkappa ratus, of which the following is a complete specification. r

The present invention relates to'apparatus for use in ditching operations and also for i use in the construction'of levees and aims to provide an improved machine adapted for use either as a ditching device or as a ma-;'

chine for building levees, the construction being particularly useful in rice plantations occupying ground having a more or less slope and requiring fromtime to time the building of levees for irrigation purposes and also necessitating the construction of a network of ditchesfor draining the fields at stated intervals.

Accordingly, I have devised an improved apparatus comprising a pair oi; blades or grading members adapted to be so mounted as to collect the earth along the line ot travel of the machine into the form of a levee in which the earth is deposited firmly and compactly by the action of the grading members,

It is also an object of the invention to provide a machine .of this character in which the grading members are so mounted and ar ranged to be conveniently ad uStable both longitudinally and transversely, as well as angularly about either a longitudinal or transverse axis. Provision is also madefor varying the heightof thesaid grading members with reference to the groundsurface;

lt-is also sought "to devise a machine ofthis character in which the wheeled support-f iiig structure comprises a full set of wheels each of which is a steering wheel and so" connected with the remaining wheels of the set that the whole supporting structure is Application filed April 13,1920.

With the foregoing genera-l objects in view, the invention will now be described by reference to the accompanying drawings illustrating one form ofarrangementjand construction which l have devised for enibodying the proposed improvement, after, which the'novel features therein will be tieul-arl'ypset forth and claimed. In the drawings; I 1 7 combined ditching and levee building apparatus constructed in accordance with the present invention; Figure 2 is a plan view of' the same;

Figure 10 is a section taken ontheline 10 1 0 of Figure [9 and Figure 11 is a fragmentary detail View illustratingmeans adapted to be employedv adjustment in effecting a transverse angular of the grading blades or member.

Referring to the said drawingsin detail these illustrate the improved construction as comprising a suitably braced skeleton frame work designated generally by the reference numeral 15,provi dedat the front and rear cornersthereofwith bearing brackets 16 for journaling a set of. steering knuckles 17 which are mounted slidingly upon the square upright shafts 18 (see Figure; 8) havingthe lower ends thereof connected rigidly to the {axles of the'severalsupporting wheels 19 of the machine. The steeringarms 20 ofthe "lniucklesfl at each end of the machineare connected by tie rods 21 (see Figure 3) with a central arm'22 on a'hit oh member'23 having thetrunnions 24 journaledin thefranie' draft member being connected by crossed tie rods 28, as clearly illustrated in Figure 3. By means of this arrangement of the connections between the supporting wheels 19,

" it is obvious that the same are movable always in unison and are obliged to follow automatically along with the direction of the draft as applied through either of the v connections to the hitch member 23.

The devices which are employed in the ditching and levee building operations comprise a pair of blade or grading members 30 which are of transversely curved form, each provided with a pair of hanger elements 31 for suspending the same from the framework 15 of the machine. The connection between the hangers 31 and the framework of the machine is such as to permit certain adjustments of the blade or grade members to conform with the character of the operation required to be performed. For this purpose the upper portion of each hanger 31 is formed with a slot 32 (see Figures 9 and 10) said slot being of T-form for accommodating the head and shank of a pair of bolts 33, whereby said hangers are adjustably secured to the framework of the machine. This part of said frame work comprises a pair of spaced frame members 34 providing a guide slot 35 between them for the passage of said bolt 33 thus permitting adjustment of said bolts along said slot 35 for varying the position of the blades 30 laterally of the ma chine. Preferably, as shown in Figure 3, a pair of the slots 32 and bolts 33 are provided for the ends of the grading blade or member 30 for the purpose of firmly and rigidly supporting the same, and the provision of the slots 32 obviously permits of a longitudinal adjustment of the members 30 with reference to the bolts 33 to a limitedextent represented by the length of the lots 32, but sufficient to meet all requirements necessitating such a longitudinal adjustment of the grading members. The slots 35 at each side of the machine are arrangedparallel to each other but at an angle with reference to the longitudinal line of the machine and in such a manner that the grading members 30'occupy a rearwardly converging relation when used for levee building purposes, having the concave faces of said members 30 facing each other, as clearly shown in Figures 2 and 3.

It may also be desirable at times to provide for a transverse tilting adjustment of the grading members 30, and accordingly I provide suitable washers 36 adapted to be fitted to either of the bolts 33 at either or both ends of the grading member 30 intermediate the top of the hanger and the bottom of the frame pieces 34. This enables the top of each hanger to be spaced more or less away from the pieces 34, and operates to tilt the member 30 in a corresponding direction, the heads of the bolts 33 being tapered adjacent to their shanks for accommodating this rocking or tilting of the hangers (see Figures 9 to 11).

Provision is also made for bodily elevating or lowering either or both of the opposite ends of the framework of the machine, for the purpose of varying the depth at which the grading members are operated or for elevating them entirely into inoperative position. As the means for effecting this raising or lowering movement of the frame comprises the same operating structure at both ends of the machine, but one such structure will be described in detail. Referring now more particularly to Figures 1 to 4 and 6, a cable 40 is connected to one of the hearing brackets 16 at each corner of the framework, each of said cables being carried over a sheave wheel 41 journaled in a bearing frame 42 mounted upon the upper end of the corresponding vertical shaft18, each cable 40 being also led around a sheave wheel 43 journaled in the frame work 15 on approximately a level with the upper brackets 16. After passing around the sheave wheels 43, the pair of cables 40 at each end of the machine are led over and secured to a pair of sheave wheels 44 which are mounted upon a common shaft 45, one of said wheels 44 being keyed to said shaft while the other is journaled loosely thereon (see Figure 6). The shaft 45 is provided with a gear 46 which meshes with a'pinion 47, which, in turn, is driven from a pinion 48 mounted on a shaft 49 provided with a hand wheel 50 located in convenient position for operation fromthe drivers seat 51 at approximately the center of the machine. The shaft 49 is also provided with a second pinion 52 meshing with a gear 53 which is fixed, by means of a pin 54 to that'sheave wheel 44 which is looseupon the shaft 45. By this means opposite rotative movement is imparted by means of the hand wheel 50 to the pair of. sheave wheels 44 for the purpose of simultaneously taking in or paying out the pair of cables 40 corresponding to that end of the machine. A suitable pawl 55-is mounted within the handle portion 56 of each wheel 50, each pawl being actuated by means of a spring element 57 within said handle portion for engaging the tooth 58 of the pawl with a ratchet device 59 mounted adjacent and co-axially of the wheel 50; this enables the said wheel 50 to be released. readily at any time by engagement of the operator with the handle portion56 and its pawl. 55,

mechanism connected therewith'set at any point after the desired raised or loweredprimarily for use in the construction of levees, such as are required for irrigation purposes on large plantations such as plantations growing rice, for example, and especially where the rice fields are located on a slope of considerable extent. The levees as constructed by the machine assume the form of terraces arranged in spaced and parallel horizontal lines extending transversely of the slopeabove referred to. building operation, the blades or. grading members 30 are arranged in rearwardly conver ing relation with reference to the hitch connection, as illustrated in Figures 2 and-3. The forward ends of the grading members or blades 30, when used in the levee build ing operation, exert a digging action, and since the blades are arranged in rearwardly converging relation, they serve to deflect the soil gathered between the blades toward the middle longitudinal line of the machine, where the soil is further subjected to a packing action by the rear end portions of the blades, where the curvature of said blades is more pronounced, resulting in overhanging projections which ride over the terrace thus built and pack it into as compact a form as is practicable with a machine of the general size and weight illustrated. Thus a single operation effects both the ditching and the collecting of the dirt necessary to construct the levee and the packing thereof in terrace form by the trailing of the improved machine along the line where the levee is desired to be constructed. All the necessary adjustments of the members 30 are provided for in the mode of mounting the same upon the framework. By appropriate adjustment of the bolts along the slots 35 the members 30 may be spread apart or moved relatively closer, to any GXtQllll desired, according to form and size of the levee being built; and

by adjusting the hangers through themedium of the slots 32, a longitudinal adjustment of the members 30 is afforded, which also enables the spread of the rearends of the members to be varied with a corresponding variation of the distance "between the front ends thereof. The provision of means for enabling the members '30 to be adjusted angularly in a transverse direction for more or less tilting the blades is'of' importance since by this means the packing action of the blades maybe suitably varied according to the requirements. The character of theraising and lowering means has already been indicated in practically full detail, the said means operating to lift the whole framework of the machine, although it is apparent that the front and rear ends of said framework In the levee may be lifted or lowered to different levels thereby resulting in'the blades '30 being positioned in longitudinally tilted relation, the angularextent of which tilt may be regulated by the propermanipulation of the raising and lowering means for the two ends of the frame. WVhenever it is desired to raise the blades 30 into entirely inoperative position, out of engagement with the ground, both ends of the framework are simply elevat-ed the necessary distance for completely disengagingthe blades 30 from'the ground.

In the operation of digging or ditching, as is required for drainage purposes (as when furrows or ditches are constructed following the slope and intersecting the levees above described) the blades 30 are simply reversed in position, end for end, and with the concave faces thereof presented outwardly; more-- over, when used for ditching,'the draftconnection is madeto the opposite-"end of the machine, for example, to-the right hand end of the machine as illustrated in Figure "It is then apparent that the forward ends ofthe blades 30 as now presented will enter the soil in the well known ditching manner, the soil being deflected outwardly by the'concaved faces thereof and thereby producinga furrow'the width of which will correspond with the maximum spread of the members 30. The same adjustments of the blade members when used in this manner, may be made in all respects as before and will'be found to possess the same advantagesv as already pointed out. I

It will beunderstood'of course thatin certain conditions, as in grading, it may be de sirable or expedient to use but one of the members 30, and this'may of course be done by simply'omitting one vof said-membersBO and positioning the other member in such a manner as will best meet the requirements of the operation to be-performed.

Theefficiency of the apparatus is increased by the described steering connections between the supporting wheels byvirtue' ofthc factthat the said wheels are obliged to con- Qstantly and uniformly fol-low along with the line of draft, thereby stabilizing the movements of the machineas well as-cau'sing the same to follow a more even and regular path.
