To all 107mm if may concern.' y Q Be 1t known that CHARLES NATHANIEL TAYLOR, a citizen of the United Statesof America, yresiding at Hemingford, in they countyfof Box `Butte and State of Nebraska,

has invented new and useful Improvements,

in Ditching, Grading, and Back-Filling Machines, of which the following is a specification.

The object of the invention is to provide a machine of the type ordinarily employed for ditching and grading wherein the' scoops are mounted for movement in paths trans-y verse to that of the machine and respectively 1n advance of and followmgthe machine-or the. supporting truck thereof for opening the path fory the machine truck to the end that" the mechanism may operate in a substantially uniform plane in its progressive movement and furthermore to economize in the ex penditure of power and time in the removal of the soil by arranging the 'scoops and the means for operating the same to successively traverse the same path in opposite directions and in alternate relation; and to provide efficient joint means for successivelyv dumping the scoops with relative uniformity and under the control of an operator positioned to control the truck mechanism and the motor by which the same is actuated; and with these objects in view the invention consists in a construction and combination Lof parts of which a preferred embodiment is shown in the accompanying wherein Figure 1 is a plan view, and Figure 2 is a side view of a mechanism embodying the invention. f

drawings,

Figure 3 .is a perspective view illustratingy the method by which the machine is advanced in operation.

Figure 4 is a detail view of a portion of the traction cable.

Figure 5 is a detail view illustrating'a supplemental traction cable. f l

The framework of the machine embodies essentially a truck 10 consisting in the construc-y tion illustrated of the longitudinal beams 11 supported by the axially pivotal wheels 12 of conventional form and mounting and a bracing wheel 13 carried by an extension'fr'ame 14 and mounted upon a fixed spindle to follow a path in substantial parallelism with the main wheels 12, and a superstructure carried by the truck and having an' uprightor mast 15 suitably braced, with a boom 16 pivotally mounted for adjustment in angular position on the ktruck and held in the detions laterally and rearwardly from the truck are front and rear spacing arms 2O pro-l vided terminally with pulleys 21 for the hoisting cable 22, terminally reeled upon the hoistingk drum 23 and extending from the extremities of the spacing arms forwardly on convergent lines to and around a direction pulley 24near the outer endof the boom. The scoops 25' of whichfone o-r more may be employed for each run of the hoisting cable, a run being referred toas the portion of the cable between'each guy-pulley 21 and the direction pulleyy 24, are' connected with the hoisting cable by front and rear chains 26, and'27 or sim'ilarflexible means suitable for the purpose indicated, the former beingv connected in eachinstance as at 28 to permit of the tilting and direction of the scoop by means of the manually' operable handles 29 scoop. f y

Pivotally mounted for swinging movement in' a vertical plane in a suitable fork 30 aty the free end ofthel boom is a dumping bar 31'from the lowerjend Aof which extends an operating cable 32, preferably around one or more intermediate guy-pulleys 33 on the boom to anoperating drum 34 which in the construction illustrated and preferably is located in' co-axial relation with the hoisting drum 23 and is within convenient control of an'engineer or" other operative ystationed' on the seat 35` and therefore in a position to clearly observe the operations of all of the scoops. l f

Extending-around the guyspulley 36 carried yby the upper end of the dumping bar is what may be termed a continuous dump' ing cable 37 in that its'terminals are con. nected with thehoisting cable at the points'l of connection yof the rear chains 27 of thev scoops with said hoistingcable, to the end that when the dumping cable is tensioned by the tilting of the dumpingfbar through the t'ensioniin'ry n of they operating cable 32, it oper# ates'to tilt and dump ythe scoop which is loaded and which is advancingin the direction of they arrow a in Figure 1, because the portion of the hoisting cable in rear of ythey loaded bucket is slackowing to the fact that making connection between the scoop traversing the opposite path or on the'other .run of the hoisting cable as indicated by the arrow b, is retracing its move= ment or is proceeding rearwardly, after being emptied or dumped, preparatory to receiving a fresh load. l

Assuming that the direction of progress of the ditching or grading operation is as indicated by the arrow c on Figure l, it will be obvious thaty the scoop which is actuated by that run of the hoisting'cable which is in advance of the truck will serve to remove soil in the path of the truck to prepare a way therefor while the scoop operating in connection with the other run of thehoisting cable will complete the operation tothe re-l quired depth, and the progress of the truck therefore may be at a comparatively uniform level, and may be effected for example by the stretching of a cable 38 parallel with the path desired for its progress and stepped or spaced rings 39 thereof, arranged at any suitable intervals adapted for the advance of the truck from time to time, and the hoisting drum or the equivalent thereof through a supplemental traction cable 40, so as to move the machine the required distance in a step by step manner as the work proceeds, said arrangement of the advancing cables being indicated in ligure 3.

Having described the invention, what is claimed as new and useful is 1. A machine of the type indicated having-a truck carrying a laterally extending boom, and a scoop carryinghoisting cable provided with runs extending transversely respectively in front and in rear ofthe truck and between the longitudinal plane of the latter and the outer end of the boom and on transversely convergent lines. v

2. A machine of the type indicated having a longitudinally movable truck, a boom carried by and extending laterally in one direction `from the truck, and front and rear arms extending laterally in the opposite direction from they truck, said boom and arms being provided with terminal guiding means, and

a scoop carrying hoisting cable traversing said guiding means and having runs extending from the extremities of said arms in convergent relations toward thev guiding Y means of the boom.
