HILLSIDE-EXGAVATO-R.

Specification of Letters Patent.

Patented Jan. 11%), 1915.

To all whom it may concern:

Be it known that I, MORTON G. BUNNELL, a citizen of the United States of America, and resident of Chicago, Cook county, Illinois, have invented a certain new and useful Improvement in Hillside-Excavators, of which the following is a specification.

My invention relates to excavators for making ditches.

It relates more particularly to excavators in which a runway is employed for guiding the bucket that travels back and forth thereon. This runway is of a shape to determine the cross sectional contour of the ditch, being arranged to extend crosswise of the latter. The bucket travels down on one side of the ditch, across the bottom thereof, and then up the other side. The dirt thus scooped up by the bucket is dumped at one side of the ditch. The runway is lowered as the depth of the ditch progresses. Ordinarily, an excavator of this kind is adapted only for work on level ground, and 1s not suitable for making ditches on a hillside.

The object of my invention is, therefore, to provide an excavator of this general type, adapted for making ditches on a hillslde, and provided with means for leveling the body and runway, by up and down adjustment of the down hill side of the excavator, depending upon the slope or inclination of the hillside, whereby the ditch, although higher at one side than the other, will always be level at the bottom thereof.

To the foregoing and other useful ends, my invention consists in matters hereinafter set forth and claimed.

In the accompanying drawingsFigure l is a front elevation of an excavator embodying the principles of my invention. Fig. 2 is a side elevation of the same. Fig. 3 is a plan of the said machine.

As thus illustrated, my invention comprises a body A supported upon wheels B and C and a tractor D. The wheel B and tractor D are adapted to travel in the V- shaped ditch, while the wheel C is arranged to travel on the bank at the down hill side of the ditch. The wheel B and tractor D may be connected with the body in any suitable manner. The outrigger wheel 0 is provided with a yoke or arch c the upper end of which is pivoted at 0' to the lower end of the screw 0 This body is adjusted up and down on this screw, by means of a nut or hand wheel 0 The pivot 0 provides an axis of self-ad ustment for the wheel C, which axis extends horizontally in the direction of the ditch. Thus the wheel 0 can always adjust itself to the angle of inclination of the hillside.

The substantially V-shaped runway E has pivoted outer sections 6, and is arranged to extend across the ditch at the head of the machine. The said runway is carried on a frame 6 that slides up and down on the frame F. This frame 6 is raised and lowered by any suitable means operated by the hand wheel G. The outer pivoted sections 6 are supported by cables or other flexible connections 6 that extend over sheaves e on the frame F. The ends of the cables or oon-- nections e are brought over the sheaves c on the frame F. Thelower ends of these cables 6 the runway E. Thus the weight of the runway is divided between the frames 6 and F, and as a result only a portion of such weight is raised and lowered by the mechanism operated by the wheel G. A bucket H is adapted to travel back and forth on the runway E, and is operated by a cable It. As shown the bucket is adapted to dump automatically in the manner set forth in in prior application Ser. No. 485,066, filed Mar. 22, 1909. However, any bucket arrangement may be used, so far as the broader aspects of my invention are concerned.

A conveyer I extends from front to rear of the excavator at the down hill side thereof. This conveyer may be operated by any suitable power transmitting connection with the engine on the body. It receives the dirt from the bucket and conveys the same to the rear of the wheel C. In this way the latter always travels ahead of the excavated dirt. There is a set of hoppers z' for the receiving end of the conveyer, and a discharge spout z" for the rear end thereof.

The engine-driven drums J on the body A are secured to the middle section of are employed for operating the bucket cable It, in the well known manner.

lVith the arrangement disclosed, the wheel B and tractor D follow the runway in the narrow ditch cut by the bucket.

' Thus it will be seen that I provide an excavator of a character to cut a narrow ditch on a hillside.

What I claim as my invention is:

1.v In a side hill excavator, a runway, a bucket mounted to travel back and forth thereon, supporting means adapted to follow the runway in the ditch cut by .the bucket, a wheel for one side of the excavator, whereby the excavator is supported at one side of the ditch, and means for receiving the dirt from the bucket and discharging the same to the rear of said wheel, but to one side of the ditch.

2. In a side hill excavator, a body, a runway supported thereon for bodily up and down adjustment, said runway conforming to the cross sectional contour of the ditch, a bucket mounted to travel back and forth on the runway, supporting means arranged to travel in the ditch behind the runway, a wheel for one side of the excavator, and a conveyer for receiving the dirt from the bucket and discharging the same to the rear of the said wheel.

3. In a side hill excavator, a body, a transverse runway thereon, means on said runway for carrying the dirt from the higher to the lower side of the ditch, means resting in the ditch behind said runway, for supporting the said body, and means bearing on the lower side of the ditch, for holding the excavator in position, in combination with instrumentalities for discharging the excavated dirt on to the ground behind the said last mentioned means.

l. In a side hill excavator, a body, a transverse runway thereon, means on said runway for carrying the dirt from the higher to the lower side of the ditch, means resting on the ditch behind'said runway, for supporting the said body, means bearing on the lower side of the ditch, for holding the excavator in position, and mechanism for keeping the said body level, in combination with instrumentalities for discharging the excavated dirt on to the ground behind the said last mentioned means.

5. In a side hill excavator, a body, a transverse runway thereon, means on said runway for carrying the dirt from the higher to the lower side of the ditch, means resting in the ditch behind said runway, for supporting the said body, means bearing on the lower side of the ditch, for holding the excavator in position, and a longitudinal conveyer disposed above the lower side of the ditch, adapted to receive the dirt and carry the same rearward to form a spoil bank behind said excavator.

6. In a side hill excavator, a body, a transverse runway thereon, means on said runway for carrying the dirt from the higher to the lower side of the ditch, means resting on the ditch behind said runway, for supporting the said body, and means bearing on the lower side of the ditch, for holding the excavator in position, mechanism for keeping the said body level, and a longitudinal conveyer disposed above the lower side of the ditch, adapted to receive the dirt and carry the same rearward to form a spoil bank behind said excavator.

7. In a side hill excavator, a runway, a bucket mounted to travel back and forth thereon, supporting means adapted to'follow the runway in the ditch cut by the bucket, a wheel for one side of the excavator, whereby the excavator is unsupported at one side of the ditch, means for receiving the dirt from the bucket and discharging the same to the rear of said supporting means, but to one side of the ditch, and means for permitting said wheel to adjust itself to the angle of the hill.

8. In a side hill excavator, a body, a runway supported thereon for bodily up and down adjustment, said runway conforming to the cross sectional contour of the ditch, a bucket mounted to travel back and forth on the runway, supporting means arranged to travel in the ditch behind the runway, a wheel for one side of the excavator, a conveyer for receiving the dirt from the bucket and discharging the same to the rear of the said wheel, and means for permitting said wheel to adjust itself to the angle of the hill.

9. A side hill excavator, comprising excavating means operating crosswise of the ditch for carrying the dirt from the higher to the lower side of the ditch, to form a spoil bank behind the excavator, said means operating to smooth the face of said bank, and mechanism resting on the lower side of the ditch, to hold the excavator upright, having provisions for keeping the machine level, together with means for discharging the dirt on to the ground behind said mechanism.

10. A side hill excavator, comprising excavating means operating crosswise of the ditch for carrying the dirt from the higher to the lower side of the ditch, to form a spoil bank behind the excavator, said means operating to smooth the face of said bank, and mechanism resting on the.lower side of the ditch, to hold the excavator upright, having provisions for keepingthe machine level, said mechanism being also provided with means for permitting self adjustment thereof to the angle of the hill, together With means for discharging the dirt on to the ground behind said mechanism.
