MORTON G. IBUNNELL, OF CHICAGO, ILLINOIS, ASSIGNOB TO FREDERICK C. AUSTIN, OF
' CHICAGO, ILLINOIS.
EXCAVATOR.
Application filed February 23, 1909.
To all whom it may concern V 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 Excavators, of which the following is a specification.
My invention relates to excavators of that type in which a bucket or scoop is arranged to travel back and forth upon a runway. In a machine of this kind the said runway is usually provided with means for upsetting the bucket and thereby automatically dumping the load at, a distance from the side of the machine. As heretofore constructed, the runway has always, so far as I am now aware, been of such character that the dumping by the upsetting of the bucket, occurred at a fixed point or points in the length thereof. It was recognized, by me, that the dumping or discharging of the dirt at a variable distance from the side of the machine, by upsetting the bucket at any desired point, was desirable, if it could be done. No arrangement for doing this was put in practice, and none proposed, so far as I now know.
The object of my invention is, therefore, to provide an arrangement for causing the bucket of an excavator of this character to V upset and dump at any point in the length of the runway or at any point within a given portion of the length thereof, and to thus make it possible to discharge the dirt at a variable distance from the excavator,
as will hereinafter more fully appear.
To the foregoing and other useful ends, my invention consists in matters hereinafter set forth and claimed.
In the accompanying drawings-Figure 1 is a side elevation of an excavator embodying the principles of my invention. Fig. 2 is a plan of the said excavator. Fig. 3 is an enlarged side elevation of the runway of said excavator, showing the operation of the means for upsetting the bucket. Fig. 4 is a view similar to Fig. 3, but with the parts adjusted to upset the bucket at a point nearer the body of the machine. Fig. 5 is a cross section on line 55 in Fig. 4. Fig. 6 is a cross section on line 66 in Fig. 1.
As thus illustrated, my invention com- Specification of Letters Patent.

Serial No. 479,322.
prises a bodyA mounted to travel on wheels 0:, or in any other suitable manner. A11 engine B with a pair of drums b and b is supported upon the said body to operate the cables C and C which operate the bucket I) on the runways E and F, which are hinged to opposite sides of the body. The runway E is shown broken away, as its exact construction is unimportant. The body, of course, has a guide or track G upon which the bucket travels in crossing the machine from one runway to the other. Said bucket isheld to its work in the excavation by the runway E, and when loaded crosses the machine to the runway F and dumps its load at a distance from the side of the machine. Preferably the bucket has wheels at that travel in the parallel tracks of the runways. Also the bucket has a draft yoke d pivoted to the sides thereof, so that the bucket may tilt about an axis. The cables C and C are attached to the ends of said yoke.
Upon the runway F there is a sliding track section H that has a depression 72, for dumping the bucket. When the wheels of the bucket run down into this depression, then the bucket is upset, as shown in the drawings. A pair of threaded rods I are mounted in bearings a on the sides of the runway F and parallel therewith. These two threaded rods are provided with traveling blocks J, which are rigid with the movable track section H, and are connected by a sprocket chain K, whereby both rods rotate in unison'to cause the said track section to move longitudinally of the runway F. In this way dumping of the load may be made to occur at any point in the length of the runway F within the range of adjustment of the said track section. Any suitable means can be employed for rotating the rods I for this purpose.
As a matter of further and special improvement, however, a shaft L is mounted upon the bodyA and suitably driven from the engine. A tumbling rod M connects the rod L with the end of the rod I at one side of the runway. By means of a suitable clutch or reversing gear N the rotation of the rods I can be reversed at will, as well as started and stopped. Thus the power of the engine is available for adjusting the dumping section H of the runway. In this way the dirt is discharged at a variable distance from the side of the excavator.
What I claim as my invention is: g
1. An excavator comprising a runway, a bucket mounted to travel back and forth on said runway, a tripper for upsetting the bucket to dump the load provided with a sliding track section, serving to limit the travel of the bucket in one direction, means for operating the bucket back and forth on the runway, and on the tripper, and mechanism for adjusting the said tripper along the runway to vary the point of discharge.
2. An excavator comprising a runway, a bucket mounted to travel back and forth on said runway, a tripper for upsetting the bucket to dump the load, provided with a sliding track section, serving to limit the travel of the bucket in one direction, means for operating the bucket back and forth on the runway, and on the tripper, mechanism for adjusting the said tripper along the runway to vary the point of discharge, said mechanism including a pair of screws carried by the runway, disposed at opposite sides and extending longitudinally thereof, means on the tripper for engaging said screws, and means for rotating the screws in unison.
3. An excavator comprising a runway, a
bucket mounted to travel back and forth on.
means for operating the bucket back. and
forth on the runway, and mechanism for adjusting the said tripperv along the runway to vary the point of discharge, said tripper providing a track depression in which the bucket upsets and comes to rest to dump the load.
l. An excavator comprising a runway, a bucket mounted to travel back and forth on said runway, a tripper for upsetting the bucket to dump the load, provided with a sliding track section, serving to limit the travel of the bucket in one direction, means for operating the bucket back and forth on the runway, and on the tripper, and mechanisni for adj usting the said tripper along the runway to vary the point of discharge, said mechanism being carried on the runway and operative for holding the tripper in position thereon.
Signed by me at Chicago, Illinois, this 5th day of February, 1909.
