T all wtomat may concern: I

Beitknown that l, FREDERIGIE. Baena, a citizen ofthe United .Statesnof America, andk resident of, Winthrop Harbor, Lake county, Illinois, have invented a .certain new and useful Improvement in Drainage-Excavators, of which the followingis a speci* fication. I. I. 1i

, My invention relates `to excavators for making ditches, and more particularly those for use in, making irrigation ditches and forfmaking ditches I,with a dike at one or eaohside of the ditch., I

The principal `object of my invention is ltosprovide a machine having meansfor cuti ting adltch,` and provided with devices for smoothing or trimming the spoil bank the machinemoves along', whereby the excavated dirt is' converted into a dike during theoper ation Aof the means .for cutting the ditch, the said devices being of such `character that the inner face of the dike is given a slope of the proper character,I it Ibeing desirable that the same caused to assumethe .angle of reposeA cf `the` excavated dirt, whereby .the loosefmaterialsare converted into Ia dike of satisfactory form as theII machine travels along in the direction necessary for the @It is I,alsoan object to provide certain details, and', featuresf yof construction and combinations ,tendingy tIoIIincrease.` the general efficiency land-I serviceability of I aI combined ditchingmachinaand dilie builder of this particularlcharacter., I I 1 I I I To these and other useful ends my inven`` tionconsifsts in matters hereinafter set 'forth anllamedlj I I.

Specification of Letters raient.

As thus illustrated, my invention comro ritnhnnrcn c.

prises a body A mounted upon front wheels B and rear caterpillars@ the latter `being operated or driven bythe engine D any suitable or desired manner. understood thatthe said enginemand cateri pillars may be of any suitable known or approved character, and `that any suitable means may be employed for controlling the forward travel of the machine. i

rfhe excavating apparatus comprises a ro`- tary wheel E mounted on therear end of a beam F, which latter is supported to swing up and down on the shaft G at `therear of lt willbe the body of the machine. Preferably, the

said shaft issupported in bearings onthe frame work ci of said body, and is disposed horizontally and transversely of the direction of the ditch, being located a suitable distance above the body of the machine, or

above the surface of the ground. Thezbeam F 1s connected with the framing a by means of an adjustable` connection H, of any suitable character, whereby the 'wheel E may be raised and lowered by changing the angle of the beam l, in a manner that will be readily understood. The adjusting connection H can be operated by hand, or itcan be operated by power and through the means of suitableconnection'with the engine. The i shaft G is provided with sprocket wheels g upon which are supported the spriocketbelts g1, said beltsextending around the wheel E, the latter being operated withsprocket teeth of any suitable character for this" purpose.` I

The excavating buckets 12," of any suitable forni or character, are mounted" on said" sprocket belts, and "arethereby `adapted travel in the direction indicated by the arrowin Fig-gl, whereby eachbucket `taires a load at the bottom of the ditch andIthen travels upward to the point of discharge above. u said point of` discharge is approximately above and a little to the right of the shaft Gr,

as shown in Fig; l, andany suitablemeans can be employed for causing the buckets to successively discharge their loads as they turn upside down at this point and pass around the said shaft. The wheel E is provided with side cutters c for forming` the sides of the ditch, these cutters being preferably bars which aresuitably" fastened -to With the construction shown," the the wheel, and which aren radially di`spo`sed` relative tothe axis of said wheel. It will also be seen, however, that these cutters, as shown in Fig. 3, are farther apart at their upper ends, when in the ditch, than at their lower ends; and that for this reason the sides of the ditch incline outwardly to some extent and are of a sloping character. The dirt shaved olf by these cutters is taken up by said bucketsvand dumped at the points above mentioned. The device for converting the excavated dirt into a dike at one side of the ditch, or at both sides thereof, comprises the cutters e1 which are suitably fastened to the sides of the wheel E, and which are so arranged that in effect they form outwardly tapered hubs for the wheel, which hubs are secured in any suitable manner to the shaft or journal e2 that rotates in suitable bearings e3, or which is supported in any other suitable manner on the lower end of the tilting beam. As shown in Fig. 3, it will be seen that the cutters c1 are disposed at an angle to the cutters e, so that any cutter e and the adjacent cutter el form an obtuse angle between them, the apex of said angle being. slightly rounded at e4 in the manner shown, it being observed that these rounded portions of the cutters are immediately above the surface of the ground. Coperating with these cutters e1 in forming the dikes X at each side of the ditch are the rearwardly extending conveyers I which are suitably supportedon the rear end of the body A and which are arranged with their forward ends in position to receive the dirt from the spouts J, said spouts being at the lower end of a hopper K which receives the dirt directly from the buckets. These conveyers I are of any suitable character, and are operated through the means of any suitable power transmitting connection with the enn gine D on the machine body. It will also be seen that the rear ends of these conveyers I are directly in front `of and in line with the cutters e1, whereby the latter are compelled to plow through the spoil or ridges of loose dirt discharged upon the vground by said conveyers.y As the excavator travels slightly forward, these cutters e1 trim or shave the inner sides of the spoil banks in such manner as to convert the latter into dike's of the proper character, the inner face o r, inclined surface of each dike having the angle of repose of the loose materials or exl vcutters el to prevent the formation of a vers berm between the dike and the side of the ditch, inasmuch as the loose dirt does not leave any exposed ground surface between the dike andthe upper edge of the side of the ditch. Thus the two dikes are formed with gently sloping inner sides or faces, and these inner sides are curved where they join the sides of the ditch, thus preventing an abrupt angle at this point, and insurin the formation of a ditch having dikes whic 1 will remain firmly and solidly in place without danger of the loose dirt sliding into the ditch after the machine has traveled forwardthat is to say, the possibility of the loose dirt sliding into the ditch is greatly reduced by smoothing or iiattening of the inner sides of the (likes, and by the manner in which the loose dirt is left along the edges of the ditch.

The devices el, it will be seen, only operate above ground on the loose dirt of the spoil banks, and do not cut the trench in the ground. But both the trench-cutting means and said devices operate about the same horizontal axis (shaft e2), which latter is transverse of the ditch.

What I claim as my invention is:

l. An excavator comprising means for cutting a ditch, apparatus for discharging the excavated dirt at the side of the ditch, to form a spoil bank, mechanism for slowly moving the machine forward during the operation of said means, and devices for properly sloping the face of said bank to form a dike as the machine moves along, said means including a wheel having cutters for forming a ditch with sloping sides, and said devices including cutters disposed in such position that the face of the dike forms an obtuse angle with the adjacent side of the ditch.
