To all whom 'Lt may concern: v

Be it known that I, LVAH D. HADSEL, States, and a resident ot Philadelphia, in the county of l?hila delphia, State of Pennsylvania, have invented a. new and useful Improvement in Slack-Cable Excavators, ot lwhich the tol lowing is a specification.

This invention relates to distant power excavators of that-type in which the scoop or ':onreyer l is movable along or upon a cable Way, composed of one or more cables, the cable may being 'so arranged as to be adapted to be slacltened to permit the scoop to engage the earth Jfor digging and filling, and to be tightened to cause the conveyer tobe operated tree from the earth during transportation in either direction.

yThe invention comprises certain details of construction hereinafter fully described and claimed, and illustrated in thefaccompanying drawings, in Wl1`1ch- F'gure l is a diagrammatic plan View representing the general arrangement of the cable Way and supporting and operating devices there or; Fig. 2 is an elevation corresponding to AFi l; Fig. 3 is a View ot the turntable support, showing the scoop in the dumping position; Fig. 3a is a detail ot the 'adjusting mechanism; Fig: l is a plan View il in* e z .sinne d ioltaeinn t leniaractei at n i Allies :in Liliid Y ip c. darin giifltaiicntr ,t antivirale.'

Way is adjustable. laterally. l'lie anchorage. means 'lll for this end ot the way includes tlexible connections 1C leading to deadmcn 1T or otherwise .suitably secured to the earth on opposite sides ot the ditch, said connections being adapted to be respectively paid out and taken in by any suitable means, but herein shown as extending to the turntable support and trictionally or otherwise connected to a winch 1S under the immediate control ot' the. operator upon the turntable and whereby a rotation of the Winch in either direction will effect a corresponding lateral adjustment of the anchorage means 1G and cable way l2. The turntable may rotate automatically to compensate `for such lateral adjustment. of the Way, or itmay be rotated positively by any suitable power devices,but Iprefer to gear the Winch 18 to the turntable as indicated at 19, to cause simultaneous lateral movements thereof.

The conyeyer is illustrated as comprising a carriage 20 having Wheels 2l rolling upon theA cable way 12 and a scoop 22 pivotally connected by links '23 to the rear end ot the carriage. The scoop has one or more dratt arms 24 to which the main draft cable 25 is attached,the same being operated 'from any suit-ably located powerdrum 25. A pair of bell cranks 26 are pivoted on a center il t "'e znzetonlingra .aen-ess. tlm ,.tront l portion il( tiene marriage ll'rithei @par rior' )taiwanais :Medir ,si
