JOSEPH W. BAILEY, OF AUGUSTA, GEORGIA,

EXCAVA'IING APPARATUS.

To all 'wkom it may concern: 7

Be it known that I, J osnrrr WV. BAILEY, a-

citizen of the United States, residing at Augusta, in the county of Richmond and State of Georgia, have invented a new and This invention relates to excavating apparatus, one of its objects being-to provide apparatus of this character utilizingv a bucket mounted for travel along a track line and which bucket is under the control of a set of cables arranged in a novel manner and by means of which the buclet can be caused to engage the ground at a predetermined point and cut forwardly thereinto so as to dig up a portion of the soil, after which the bucket can be used for conveying the engaged soil to a point where it is to be dumped, the dumping operation being effected by the manipulation of certainof the controlling cables.

A further object is to provide apparatus of this type especially suited to deep excavations where it is necessary to go to a considerable depth for the load and to hoist the load quickly to the point'of delivery.

A further object is to provide excavating apparatus in which the bucket can be dumped at the will of the operator while going at full speed backwardly or forwardly 'ment of the hoist 1'01, ifdesired, the mast or which can be operated to dump the load after the bucket has been brought to a stand, it being unneccesary in any event to use any'kind of a stop or buffer in order to effect the dumping.

Another object is to provide'a carriage which constantly remains in position on its track line and is not to be lowered with the. bucket during .the loading operation, this resulting in a considerable saving of wear and the conservation of power.

A still further object is to provide a car-- riage and a bucket supporting block so shaped as to fit snugly one within the other wvhen the bucket is in its raised position thus to provide a rigid structure movable along the track. line.

A further ob ect is to provide means whereby the bucket can be made to dig at any angle desired, thus to meet the condition of the material to be dug.

lVith the foregoing and other objects in view which will appear ;as the description proceeds, the invention resides in the combination and arrangement of parts and in 1 is adapted to travel relative thereto.

The track line supports a carriage (lhaving wheels'YJfor engaging the-track line Specification of Letters Patent. .Paten'ted Feb, 191'? Application filed May 13 1916. Seria1 No.'97,351.

the details of construction hereinafter. de-

scribed and claimed, it being understood 7 I that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention. I

In the accompanying drawings the pre-' ferred form of the' invention has been shown.

In said drawingsz- Figure 1 is a side elevation of the complete excavating apparatus.

Fig. 2 is an enlarged side elevation of the bucket in, digging position, adjacent parts of the apparatus being shown.

Fig. 3 is a side elevation of the bucket in. V traveling position.

Fig.4 is a side elevation of the bucket in dumping pos t on.

' Fig. 5 is an elevatlon of i portion of the apparatus and showing a modified co nstruc-- tion. 7 I p p 7 Referring to the figures by characters of reference. 1 designates 221 11 ordinary hoist of that type utilizing three independently operating drums. 'This hoist has .a mast 2' to which. is connected. one end of a track line 3, the'other vend of the track line being attached to a" mast or tower 4:. This tower or mast can be mounted for movementalong a track ,5 parallel with the, path of moveor tower t can be stationary while the hoist and depending from the end portionsv of the'carriage, are hangers; 81in which are journaled sheaves 9 and .10 respectively.. The carriage is provided ineach sldew th a \l-shaped recess 8' for the purpose here1nafter pointed out. v

The three drums .on the hoist 1 are designated at. 11,12 and 13 respectively, the

drum 11' constituting the hoist drum and sheave '16 mounted in a block17 at the up-v per end of a yokelS. This bloc'khas an The lower end of the yoke is pivotally conangular .extension'17. at the top thereof. 7

neeted to the closed sides of a bucket 19 close to the open front end of said bucket, the rear end of the bucket being closed and connected by one or more chains 20 or other flexible elements to the upper portion of the yoke 18. Thus under normal conditions the yoke 18 and chain 20 will cooperate to support the bucket 19 in a substan tially horizontal position, as shown in Figs. 2 and 3. Extending from the bottom of the bucket at the open end thereof and preferably at an angle of 25 is a digger 21 which can be in the form of a lip or of a series of teeth. Arms 22 are extended forwardly from the sides of the bucket and these arms are connected by chains 23 or other suitable flexible element to a ring 24 on a haul or digging cable 24 extending over a guide sheave 25 on the mast 2 and secured to the hauling drum 13. Another chain 26 preferably connects the haul cable ring 24 to the block 17 while a third chain or other suitable flexible element 27 may be used, this chain connecting the haul cable ring 24 to the back portion of the bucket, as shown in Figs. 2, 3 and 4 and having a hook 27'. This chain 27 is adjustable in length and can be easily lengthened or shortened by .drawing it through ring 24 and placing hook 27 in engagement with any of the links of the chain. Thus the operator by lengthening or shortening it can make the bucket dig at any'angle desired, thus to increase or lessen the digging tendency according to' the density of the material to be du Secured to the back of the bucket 19 is a dump line 28 extending upwardly over a guide sheave 29 in the upper portion of the yoke 18, thence through a sheave block 30 and back to the block 17 to which said line is fastened. The back haul line 31 is connected to the sheave block 30 and extends to a guide sheave 32 on the mast or tower 4 and thence across the excavation to the back haul drum 12, this back haul line 31 being guided by a sheave 33 on the mast 2 and by a sheave 34 carried by the hangers 8 of the carriage 6. If desired and as shown in Fig. 5 the block 30 can be dispensed with and line 31 extended around sheave 29 and attached to the back of the bucket. The bucket while moving upwardly and backwardly moves at such an angle that the pull through the line 31 would not be sufiicient to dump the bucket unless tension should be placed on the cable 24. 1

.Assuming that the bucket is suspended close to the mast 4, the same can be lowered to the ground by paying out the

cables

14 and 24. By then simultaneously paying out the cable 31 and taking up the cable 24 the bucket will be caused to travel toward the hoist 1 so as to dig into soil. The bucket It can then be drawn toward the hoist 1,-

it being of course necessary to payout the back haul line 31 during this operation. As

soon as the bucket has been brought to a position where the contents thereof are to be dumped, the haul line 24 is brought to a sufiicient tension to cause the back haul line 31 to pull, through the sheave block 30, upon the dump line 28, thus to cause the back end of the bucket 19 to swing upwardly to the position shown in Fig. 4.

Should it be desired to convey the bucket in the opposite direction. prior to dumping the contents thereof, it is merely necessary to pull upon the bucket through the back haul line 31 and the dump line 28 and at the same time to restrain the bucket by holding back on the haul line 24. Thus the bucket will be conveyed toward the mast or tower 4 without dumping but as soon as it has reached a point where the dumping is to be effected, the haul line 24 is brought to suflicient tension to cause the dumping of the bucket, as will be obvious by means of lines 31 and 2S.

It will be obvious that the dumping can be done at any point within thespan of the apparatus. Chain 27 may be so adjusted as to hold the bucket in proper position for digging up close to the hoist, thus to produce a steep bank. By using this form of apparatus the hoist can be placed on top of the material to be moved, if so desired and material conveyed on an inclined track line to the mast or tower and there dumped so that the digging is thus done close to the engine, resulting in a saving on the haul line for the reason that only. a short length of the line is off of the drum while the diggging operation is in progress and the operator has a close and unobstructed view of his work.

When it is desired to handle mud or other material containing a large percentage of moisture, the chain 20 can be extended or paid out so as to allow the back of the bucket to normally rest lower than the front portion thereof, thus preventing spilling and assuring a full load when carried to the dump.

By using the sheaves 34, it becomes unnecessary to employ any supplemental fall line carriers for supporting the slack in the back haul line where a long span is used.

Importance is attached to the particular arrangement of recess h and the angular extension on the block 17 it being apparent that when this extension 17 is seated in the recess 8' the block 17 will be held rigid with.

the carriage While said carriage is-tr-aveling along the track line, as shown particularly in Figs.- 3 and 4.
