citizen ci the United States, residing. at

Dori."ancetlni`v in the countyl of Luzerneand i vState of Pennsylvania, have invented-a new' andyuseful Eucavator, of which the follow-,

'ing is a specification. v

chinos which, are known in the trade as dis-l tant power devices, and has particular reiterence 'to a -novel construction of digging and'carrying bucket together with certain i improvements in means or devices 'for open -.a.t1ng the saine, all as Will Ybe hereinafter fully described and claimed', and illustrated inthe accompai'iying drawings, in which Figure -1 is a planview of the bucket; Fig.

l2 is .a side View of the same;` Fig. 3 is a transverse vertical section on the lin'eB-B of Fig. 2 Fig. t is a View oi' the bucket showing the same diagrainmatically in operation in full' lines,v the bucket being carried or transported in dash lines, and the same be'- ing dumped in dot and dash lines; Fig. 5 is a plan View ofthe devices covered by Fig. `Il; Fig. G is a diagrammatic side elevation of a slightly modified 'termoli bucket and a modified arrangement ci supporting and operating mechanism; Fig. 7 is a like View of a similar form of bucket and. a diii'erentau rangement of'operating devices, andlig is a detail ofcertain tripping mechanism hereinafter described.

Throughout the: `following detail description and on the several figures ofthe draw ings similar parts are referred to by likereference characters.

Referring particularly to the detail Views,

the numeral 10 illustrates a cradle orframe,y

provided with a. front shaft 11'anda`rear shaft- 12 on which are mounted supporting Wheels 13 maintained in rolling 4contact with track rails or cables 14 by means of shoes or rollers 15 mounted upon the cradle. The track cables 14 are anchored at their rear end. at any suitable distant point, and are adapted to be tightened` by any-suitable mechanism so as to lift the'buclet clear of the ground for transportationand dumping y purposes. The means herein shown Jfor the purpose of tightening the track vcables consistsof a pair of pulley blocks 16 to the upper onev of ,which is Vconnected a cable 17 which is mounted upon a drum 18 under the control of the engineer.

`The scoop portion 19 of the bucket is mounted Within the cradle 10 and is pivotcd-'thereto on pivots 20vnear its front end so that under ordinary conditions as when Q l ,y under transportationthe body of the scoop Tnisinyention relates to excavatin ma.-v

will be carried in the position indicated in dash lines in Fig. 2, the rear portion of the scoop being provided with one ormore hooks 21 adapted to engage over the axle 12.

Oneor'moredraftbeams22 are rigidly con nected .in any,,siiitable manner to the front portion of the scoop and hence bear ay certain-denite angular relation tothedigging edge 2 3 thereof, the arrangement being suchthat the digging edge or Joints of the scoop will always be sure to ig into'the earth when the bucket is loweredto filling position. Any suitable means 'may be provided to prevent the scoop from digging tooA deep or being overloaded, and to this end l have shown atl 24 a cross plate or member carried by the beams 22, which When the scoop becomes filled will cause the same to be thrown out of digging position. lVhen the scoop is being filled byv draft on the lropes 2.5 and beams 22, the excess of dirt which` gathers in frontof vthe cutting edge 23, after the scoopV is full, Will form a hummock, which Vwill throw the cutting edge lout of cutting engagement by reason of the plate 24 bearing4 down upon and over 'said humrnock. @ne or more draft cables 25areconnected to the aforesaid beams 22 and extend thence forwardly over any suitable direction pulleys-26 to any suitable form of power drum 27.

'AS indicated in rig'. 4 uiebucket win be' drawn'toward thepower station by direct operation of the cables' 25 until it becomes loaded, at which time or immediately thereafter the supporting cables 14 will be tight erred to lift the same 'out of contact with the ground, and then the cables 25 will be slackened, permitting the scoop to assume., the carrying positionv indicated in dash lines in Figs. 2 and 4. One or vmore tailI ropes 28 are connectedfto they rear portion ,of the ybucket.' cradle 1 0 and extend thence rearwardly over any suitably located.'direction pulleys 29, thence forwardly to and over 'pulleys 30 to another'fpower drum 31 with- ,in reach of the engineer; By operation of this last mentioned ldrum' the tail ropes 28 will cause the bucket and its load to be conveyed rearwardly over the point of deposit where the scoop may be tiltedby any suitable mechanism. The scoop may be provided with an upwardly projecting tailpiece' 32 which may consist of a pair of .plates secured to the framework of the scoop and converging at their upper end where a roller may be mounted, said roller being adapted to travel along a trip cable Sle'ai'ichored at one end and provided upon the tail ropes 28 will cause the scoop atits other end with a tension weight lSaid cable-34 may be provided with a stop vbutton 36 adapted to be placed at any point where it is desired to tilt and dump the scoop.v Then the bucket and its load are drawn rearwardly the tailpiece will en'- gage the button. 364 and a continued pull to be lifted and tilted as shown in dot and dash lines in Fig. 4. The scoop being pivoted. eccentrically it will automatically right to the loading position.

itself when permitted to go forwardly again The supporting and operating devices of ,this present invention are adapted for a 'greatliexibility of use both as to adpistnient or sett-ing along the lines of the excavation or transversely thereto. As shown in Figs.

'aforesaid sets of trucks, said motor being under the direct control of the engineer on the power station 37. Each pair of rails 39, or 39 and the devices supported thereon aremounted upon trucks 41 movable par allel to the line of` excavation on track rails l l 42. Said movement of the trucks 4l may be effected by any suitable means either individually or together.

In Fig. `6 is shown an arrangement quite .analogous to that hereinbeforedescribed inthat the cradle 10 is supported upon track lines or cables 14 and is movable toward the power station by means of cables -25 for lilling and conveying purposes. The f power `mechanism, however, is mounted upon a barge 37 from which extends rear-v Wardly a boom 40 which corresponds to the i aforesaidfanchor tower 40- to which the track .cables 'are Iconnected and over which the tail ropes 28 operate. TheV dumping is effcted -in thisform of the invention in a slightly different manner by the provision of a yoke 43 suitably arranged lso asl to engageover the tail-piece 32"of. the scoop. The yoke .by engagement with `the tail-piece will cause 'the scoop to tilt as indicated `in dotted lines in Fig. G upon permitting the draft cables 25 to slacken, and a continued reverse movement of the bucket will cornpletely dump the contents and cause the tail-piece 82 to automatically release itself from the yoke ready for a, succeeding operation.

In the form shown in Fig. 7 the construction and operation of the bucket are prac-- tically the same as in Fig. (3, 4but the power tower 37a is indicated as being substantially stationary and likewise the anchor tower 40"- is lined on its own support.V

Figi 7 shows the manner of mounting and. supporting the yoke 43, the same being shown as carried by a trolley 43 adjustable along the track cables 14, and secured at; any desired position of adjustment by means of a tail rope 43" which may be anchored at any suitable point on the adjacent tower.
