An'object of my invention is to provide a novel sled type bucket which may be tilted and Otherwise operated by remote control.

A further object is to provide novel means in a device of the type described which will prevent the bucket from capsizing when in operation.

A further object is to provide novel means for holding the actuating lines out of engagement'with the ground;

Other objects and advantages will appear in the following. specification, and the novel features of the invention will be particular- 1y pointed out in the appended. claims- My invention is illustrated in the accom: panying drawings, forming part of this application, in which Figure 1 is an elevational view of. my invention as usedin constructing levees,

Figure 2 is an elevational view. of my invention as in operation,

Figure 3 is an elevational view showing the bucket and its associated mechanism during the digging operation,

Figure 4 is a perspective view of the bucke and associated mechanism, and

Figure 5 is an elevational view showing the bucket and associated mechanism subsequent to the digging operation.

In carryingout my invention, I provide an operating tower or derrick 1 and an anchor tower 2. The anchor tower 2 is normally positioned at a distancefrom the actuating tow: er 1. Both of said towers are, however, transportable by reason of the fact thatthey may be mounted on any suitable transporting means such as Caterpillar tracks 3.. The operating tower 1 is of much greater height than the anchor tower 2 for the reasons hereinafter described and is positioned adjacent the location where. the levee is to be built. The tower 1 is provided with a housing 4 in which an operating mechanism or. machinery is disposed. A supporting line or cable 5 is operatively associated with the operating mechanism in the housing 4 and extends over a wheel 6 mounted on the top of the operating tower 1 from whence it extends to the anchor tower 2. The supporting line 5 extends over a wheel 7 rotatably mounted on the anchor tower 2 and is operatively connected withmachinery disposed within the housing 8 ofsaid anchor tower. Y

As shown in Figure 4. I further provide a bucket or receptacle 9 having an end wall 10, side walls 11, and abottom wall 12'. The top and an end of the receptacle are open as shown in Figure 4. The bottom Wa1ly12 is provided with a projecting-portion 13 which is positioned at an angle with respect to said bottom wall. The side walls 11 are also provided with projecting portions 14 which are connected with the projecting portion 13 and serve as means for reinforcing the same. The projecting portion 13 functions as a scoop or shovel as will be hereinafterdescribed. Each of the side walls 11. is provided with a lug 15 fixedly connected therewith and a projecting lug or flange portion 16 connected with the top edge thereof. A carriage 17 ismovably mounted on the supporting line 5 by means of wheels 18 mounted on the carriageand traveling on the supporting line 5.

A supporting chain or link means 19 is pivotally connected with the carriage 17 by 30 means of a pin 20 and is connected with a pair of. diverging link portions 21 which in turn are connected with the lugs 15. A spacing member 22 is disposed between the divergingmembers 21 for holding the same in a definite spaced-apart relationship. An actuating line or cable 23 has one end pivotally connected with the carriage 17 by means of a pin-24 and extends over-a wheel or pulley 25 rotatablymounted on the operating tower 1 from which it extends to al rotatable-drum 26 on which it is wound, said drum being carried by the operating towerand operatively associated with the operating mechanism disposed within the housing 4. A spacertrolley 27 comprises a pair of spaced-apart

wheel carrying elements

28 and 29 on'which are'respectiv'ely' mounted wheels 30 and 31. The Wheel 30 travels on the supporting line5 and the wheel 31 travels on the actuating cable 23'.

ber 32 connected'with the

wheel carrying elements

28 and 29.

A depending link means 33 has one end pivotally connected with the wheel carrying element 29 and the other end connected with a connecting member 34. A draft line or pull ing cable 35 has one end connected with the connecting member 34 and extends over a pulley wheel 36 mounted on the, derrick 1. The draft line cable is wound on a drum 37 rotatably mounted on the derrick l and operatively associated with the mechanism disposed within the housing 4. A pair of draft members or link elements 38 isprovided for connecting the flange members 39 mounted on the receptacle 9 with the connecting member 34.

A pair. of telescoping arms 40 is connected with the oppositeSi-Ydesll of the bucket 9 and the respective draft members 38. Each arm 40 comprises a female arm portion 41 having an end connected with a side of the casing and a male arm portion 42 having an end connected with a draft member 38. The male arm portioniss'lidably disposed the female armportion and is provided with a lug 43 extending through a slot 44 in the female member for limiting the movement-of said male arm portion relative to the female arm portion. I f

A cable supporting trolley 45 is provided comprising aYsupporting member 46 and a supported member 47. A tie member 48 is provided for connecting the supported memher with the supporting member. A supporting wheel 48 is rotatably mounted on the supporting member46 and travels on the supporting cable 5..

Spaced-apart supported wheels 49 and 50 are rotatably mounted on the supported member 47 and are adapted for respectively supporting the actuating cable and the landing cable beneath which said wheels are posi tioned. A tie or anchor line 51 is'connected with the cable'supporting trolley 45 and the operating tower 1. The cable supporting trolley may be anchored to the tower at any suitable distance therefrom. A number of these cable supporting trolleys may be utilized depending on the length of span of the supporting line 5. o

From the foregoing description of the various parts of the device, the operation thereof may be readily understood.

lVhen it is desired that dirt be: piled up for constructing a levee the operating tower is first position adjacent the location where the dirt is to be piled and the anchor tower is positioned at a distance therefrom. The bucket 9; is first positioned adjacent the anchor tower 2 and the tension on the supporting line 5 is released whereby the bucket may be disposed on the surface of the ground,

26 is then rotated sufficiently for exerting enough tension on the actuating line 23 for moving the trolley carriage 17 to theposi- 1 tion shown in Figure 3 relative to the bucket 9. When the trolley'carriage 17 is moved to the position shown in Figure 3, the spacing member 22 engages the lugs 16 of the bucket thereby tilting the bucket to the position shown in Figure 3, at which time the scoop or shovel portion 52 of the bucket will be in its digging position with respect to the ground. The drums 26 and 37 are then rotated at the same rate of speed,provided that they are of the same size, so that the carriage 17 and the bucket 9 move at the same rate of speed thereby holding the bucket in its tilted position and causing the same to be filled with the material which it scoops from the ground. When the bucket has been pulled along the ground a sufficient distance to enable it to become filled with material, the tension on the actuating line 23 is temporarily released, at which time the bucket assumes the position with respect to the trolley carriage 17 as shown in Figures 2, 4, and 5, whereby the shovel portion 52 will be moved out of engagement with the ground so that as the bucket member continues its movementalong the ground it will not continue to load itself with material. i I

The bucket is of. the sled-runner type in that the cutting edge of the scoop portion is positioned above the bottom of the bucket. When the bucket is pulled to the position where it is desired that the load be dumped power is applied to the supporting line 5 for tensioning the same whereby the bucket may be lifted from the ground. The tension on the actuating line 23 and the draft line 35 is then released. whereby the bucket may drop to the position9a for dumping its load 3 as shown in Figure 2. It will also be noted that the track line 5, when in tension, is positioned at 5a. It will also be noted that when the track line 5 is under tension that the cable supporting trolley 45 is positioned at 45a. Thus it will be seen that the cable.

trolley 45, together with the spacer trolley 27. serves to keep the actuating and draft cables, together with the draft members 38, out of engagement with the ground regardless of the position of said bucket. lVhenthe bucket has dumped its load the drums 26 and 37 are rotated for slackening the actuating cable 23 and the draft cable 35 for permittion 52 thereof should engage an obstacle such as a large rock. The telescopic arms also aid in positioning the bucket at the proper angle with respect to the ground for the digging operation.

The arms 410 permit the bucket to be manipulated without hindrance.
