i To all itimay concern:

' Be knownthat I. CHARLES L. VVAoH'rna a citizen oftheiUnite/d States, and a resident of New'York city, borough of Manhattan, in the c ounty'ofLNew York and State of New Yor'khhave.invented certain new and useful Improvementsy 'in Cablewy Excavating Systems,jof \vhich the following is a specilicationii': f l

:My inventionrelates to new and useful improvements vfin cableway excavating sysl temsyandvmore particularly to thatcharacinto thefr'naterial to be excavated, the bucke f ter` orftype in' which a digging bucket o1 scoop is suspended from a cableway, and may beflowered therefrolnto be dragged .liorvscooplvbeing.movable lengthwise of the cableway in Vdigging and carrying its load.

and lalso when being moved to the point of ,exeavationgafter having dumped its load.

The inventionv Aconsists in the improvel ments tobe fully described hereinafter and p. the. novelty v`ofwhich will be particularly pointed out and distinctly claimed.

I' have fully and clearly illustrated my invention` vin the accompanying drawings to be taken as a part of this specification and wherein-f Figure 1 is a view in side elevation of an excavating system exemplifying an embodi-l sions and. designto suit theconditions underwhich they yare employed, .said towers beinglocated vwith the material or space to be excavated betweenthem. Preferably the head tower ismade of a height ygreater than the tail ltower for a purpose to be presently set forth-: ,l p

Mounted 'on' the head tower 1, is a rope "guide consisting of a sheave 3, and a rope '-lguide such as af block 4 is fixedto the tail l to. whichis vwound on the-drum 6 oa hauling *originel-at the footofv the .head tower,' the tower,r and passing over these yrope guides is. a main` supporting cable 5,1lone end of oppositefend of .the rope passingpover the CABLEWAY EXCAVATING- SYSTEM.

Y Specication of Letters Yatent.

to a load carriage'7 arranged to travel on the part 5. This arrangement is such that a pullon the rope 5 by the drum 6 will serve to draw the carriage'out toward the tail tower 2. y f

Connected to the carriage is un inhaul line 8 which passes from its Lpoint of connection to the carriage toward .the head tower and rope guides 9,110 thereon and down onto the drum 6,yl1p0n which it is wound reversely from' the rope-5;- Itwill be seen that the ldrum 6 uponfbeingfrotated in v one direction will takeup the line 5. )t'o pull thecarriage toward'the tail tower :during which operation the line 8 will be .paid out; while the drum upon being rotated in the other direct-ion will take upV the line 8 to pull the carriage toward the head tower and the cable 5-.will be paid out. y g

Means is-provided for adjustingy the elevation ofthe malin-cable 5 so as to regulate the height of the carriage relative to the mat-erial being excavated; this vmeans prefer- 'ably consists ofa loop in'one of the carriage'hauling lines which loop istake upl or paid out to lengthen the main cable 5. The loop is preferably formed in the inhaul line 8, as at 11, between the rope guides 9,10 and depends from said guides within the head tower 1, the closed end of the loop passing through a block 12, which. is connected lto one block 13p` of a running connect-ion14, the other block 15 ofwhich is anchored at the base of the head tower, the free end of the line of the running connection being wound upon a drum 16. Bythis arrangement the drum 1.6 `can pull down or let out on the loop 11, so thatthe main cable will be drawn taut orfslackedI oil' as may be desired.

Suspended Vfrom the carriage by:r ai1yr-'sluit able means isa scraper or excavatingbu'cket 17 which may be ofthe type illustrated in f the patent to page 758380, dated. April 2l, 1904, in which the bucket body is suspended loo n by a bail pivotally connected thereto at a point behind the center of gravity offsaid 4bucket so that the latter auton'niticallyv Connected to the .forward end of the bucket is a digging line l'whichv passes .bein y20 over aguide sheave 19 on the head tower 1 and is then wound onA a ldrum 20. The' drums 6 and20 maybein the same engine as, for instance, one of the t-ype shown in the patent granted Miller and Dickinson August 20, 1901, Number 680934, but this is not essential as the drums may be op erated in any manner desired, and need not l be in a single enginepstructure.

When the system is to be operated, the lparts arey installed in substantially the arrangement shown and described., it.v being premised that the carriage and bucket are adjacent the head tower and that the digging is toltake place from the tail tower towarglthe head tower. The drums and held stationary, thedrum 16 is operate to take up the loop 1I, and thereby pulls'the main cable 5 taut to raise the carriage and bucket to substantially. theposi- 4 tion shown in Fig. 1. The drum 16 is then held and drum`6 is rotated to take up the rope 5 to outhaul the carriage and bucket and at the same time let out the inhaul line 8, thisoperation being continued until the bucketueaches apoint on the other side of a that where the excavating is to take place.

carria During the outward movement of the and bucket toward the tail tower \the in auling line 8 is paid out, so that the carriage will have free movement along the able 5. When thev carriage and bucket have reached the desired position, vthe drum 16 is rotated to pay out the running connection 15,. to slacken the loop and thereby lower the main cable, so that the bucket may be brought'down to engage the material to be excavated, and this having been done,l said drum yis held so as to prevent further slack ning of the main cable. The drum 6 is th n rotated in a direction op osite to that ust scribed as is also the rum 20, so t at the cutting end of the bucket is drag ed into the material to be excavated,

`whereby the material is lowered into the bucket.`\. The bucket having received its load, the drum 16 is then revolved to pull in on the loop 11, so as to take upk the main cable and raise the carriage and loaded bucket, after which the drum 6 is revolved to take up the 'inhaul line 8 to traverse the carriage and vbucket aloncr the main cable to the point where the load is to be dumped.

When the bucket .has reached `the point where its load is to be deposited the drum 6 ma. be stopped and held against rotation an the di ging line is slacked4 olf so asl e weight of the' load to throw the forward end of the bucketV d wciiereby the load is dumped. The running.

connection fis then. pulled` into take uppthen main cable to raise the y carriage and the sameisnutbauled by revolvmg-the drum 6- to take up said main cable, the lines 8 and 18 being paid out to permit the carriage to move toward the tail tower, after which the digging operation as heretofore Idescribed, -may again .take place.

'The tail towerlis preferably of anv elevation less than thehead tower in order that ,the lcableway may have the proper inclination to permit the 'bucket to dig properly, and also in order that the bucket may, 1f desired, be permitted to gravitate toward thetail tower-instead of pulling it out by the main cable as described.

Having thus described my` invention, f what I claim as'new and desire to secure by, Letters Patent is I 4 1.
