To all. whom itmay concern:

Be it .known that I, HENRY G. BUTLER, a citizen of the United States, residing at'Keno she, in the county of Kenosha and State of Wisconsin, have invented a new and useful Improvement in- Scraper-Operating Apparatus, of which the following is a specification.

My invention relates to an improvement in the class of apparatus involving cable-wind ing mechanism for operating ascraper, dredge or other. form of conveyiug'means; such as would be employed in railroad grade and levee construction, dredging, excavating ,for foundations and sewers, for feedingclay to'the fire in burning clay to make ballast, and in stone-quarries, and the like; audit relates, more definitely stated, to an improvement in the class of such mechanism in which the winding mechanism involves a-pair of winding-drnms supported on a preferably 1000- motive base, such as a car or boat, and driven by a suitable engine-and controllable to produce the three filling, hoisting and conveying operations of the scraper.

My improved apparatus is advantageously applicable to any of the uses referred to, but for the sake of convenience and to avoid prolixity', I confine the description hereinafter to use thereof in connection with ballast-burning and illustrate it in the form best adapted thereto in the accompanying drawings, in which- Figure l is a view in end elevation, diagrammatic in its-nature, of the apparatus; Fig. 2, a section. taken at the line 2-2 on Fig. 1, viewed in the direction of the arrows, and enlarged; Fig. 3, a broken enlarged view showing drum and connter-shaft mechanism-- in sideelevation with their sheave-connecting beltsin dotted representation; and Fig. 4, auction taken at the line 4 on Fig. 1, viewed in the direction of the arrow and en- A is the support for myimproved mechanof a car movableon a track r, which maybeconsidered, for the purposes of the further description, to extend alonga pile of burning clay or ballast-burning fire, toward which the boom B pro- C is a tower or mast structure extendvand comprises expanded able or well lguowu construction.

the car to which, in a usual or any suitable manner, is attached the boom, preferably by pivotaliy supporting it at its inner end and,at its outer end,by stayrods or cable o fastened to the upper portion of the mast. I r

D and E are drums loosely supportedon rotary shafts p and o jourualed in suitable supports on the car and provided with clutchmechanismfor causing, at will, 'the drums to rotate with them. The clutch-mechanism is preferably of the friction-clutch; variety, I disk-heads n and m of the respective-dru ms, having flange-extenalone n and m widening outwardly to form the female'partsof theclutches, and thedisks n and m secured on the shafts and having tapering flange-extensions n and m to receive and be engaged by the flange-exten. sions n and m. As rneans for working the drums back and forth on their shafts to clutch and unclutch them, each may be provided (see Fig. 2) with a worm-collar o operated by a-haudle' 'v' to work in a journal-bearing o the respective shaft. The disksn 'and m, which are made hollow for lightness and economy, are provided circumferentially with cogteeth t, engaged by an interposed pinion F on the rotary driving-shaft F, driven by any suitable engine, (not shown, but preferably of the double cylindenand. piston steam variety.) Thus the two shafts p and "'o'with their clutch-sections nand m. are constantly driven iu'corresponding directions and accordingly drive the drums when clutched to them.

G is a counter-shaft journaled in suitable bearings in the upper portion of the car, and carrying, near one end, the fast pulley l, and near the opposite end a k and 1., adapted to be alternately engaged with the countershaft to rotate with it by means of an interposed clutch H of any suit The pulleys k and iare connected with pulleys k and 11, fast on the shaft p of the drum D, respectivelyv by a straight endless belt k, and a crossed endless belt 1?,- and the clutch-disk m of the drum E formsa pulley connected bya straight endless belt Z with the fast pulley Z ou-the countershaft.

scraper set forth in my .Serial No. 446,294, filed on tember,189.3. From the ward end, the scraper drum E by a cable a woun v a. desired nutnberof times, proceeding then over a sheave 9 under a sheave-carriage 1 extension cl on its base of which the hangers of the scraper is pivotally supported. From the carriage the cable proceeds ever a-guidehaving a bifurcated between the prongs the end of the boom where it.

with a hinged when closed, by a catch s, the latter may ble 3 with a sheave an end of the drum-shaft 0 carry 5- loosely supported the shaft at will.

I prefer that the pulley 9 shall be vertically movable, and to that end supportitin ablock g' confined between vertical guides g in the ded, on a sheave w journaled on the upper end of the mast at one end of a cable 0, the opposite end of which in all respects like the pulley g, being supported-in a block confined to move vertically in guides f. The pulley f should be considerably heavier as 'by weighting, to cause mast-structure and suspen is connected with a pulley f,

than the pulley g, it the better to counterbalance the scraper and to take u the scraper is filling. The p the latter a .ble 0 ing thence over its opposite end the pulley f and fastened to. a stationary object, as

' the base of the mast.

The operation is as follows: Supposing the scraper to be down on the ground in positi to be dragged toward the car A to fill, a

the shaft F to be in motion in the direction Fig. 1 (whereby the vcontinuously in the direction indicated by arrows) then by E to its shaft othe cable indicated'by an arrow on shafts p and 0 will be rotatt clutching the drum 0 will be wound al'the length between t drum E and .the draft-bar h and drag the scoop toward the car, thereby filling it, vt

practically endless cable 0 meantime paying direction to permit the out in the opposite A described hauling or dragging thereof. '1-

V clutch of the drum E is then actuated to re:

lease it, and that of therear drum'D actuat to clutch the latter to its shaft, whereby 1;

cable 0 is wound thereon and thus shortened,- downwa'rd the block f and consequently raising the block 9', which atthereby pulling e bottom and permit it to fall for d u mping the conteh ts of the scraper, by connecting it through the medium of -a caing a suitable clutch s for engaging the sheave with p" the slack. of the cable 0, and the exertion scraperlsimnltaneeusly at its hanger-bars and draw-bar. When the scraper has been thus lifted to the desired elevation, the drum D is unclutched and a brake applied to quickly overcome its inertia.

fects hauling up the of a rapid lift on the metal band e supported to extend circumferentially about the upper portion of the periphery of the diskifiange n and having its ends connected with a foot-lever 'e', whereby pressure on the lever will tighten or clamp the hand against the disk. Then the scraper is rapidly carried outward to any desired distance toward the end of the boom B, to the 1s tal the pulley ito the counter-shaft, whereby the crossed-belt-connection of the drum-shaflt pulley 'i' with the counter-shaft rotates the latter in a direction which effects, through the pulley Z and belt I, rotation of the clutch disk m and drum E in a direction contrary to that already described thereof and indi-' 'cated by an arrow, causing the cable 0 to pay out accordingly between the drum and scraper draft-bar h. The inertia of the scraper in proceeding'to the point of dumping is quite great, so that its momentum is sufficient, on releasing the clutch H and applying the clutch s when the desired point of dumping 'is reached, to trip the catch s and permit the scraper-bottom to fall. Thereupou the scraper is rapidly hauled hack to the point of filling byclutehing the pulley k on the counter-shaf t G, whereby it is rotated, correspondingly with the drum-shaft'p, in the direction causing its pulley Z and belt-connection with the clutch-head m on the drum E to rotate the latter rapidly inthe direction for winding upon it the cable 0 from the scraperhanger h. \Vhen the scraper -has thus been quickly brought to thefilliug point and the brake on the drum D, released to permit the scraper to drop into the pulleys f and g tions in which they are iliustrated, the counter-shaft pulley k is unclutched and-the drum E is again clutched to its shaft 0 to be thereby rotated in the direction to effect, slowly, the refilling of the scraper, whereupon the hoistat to on nd the loaded scraper are again successively produced in-the manner already described.

Theoperations of liftingthe scraper, carr ing'it to the point of dumping, and returning it to the idly by ameters of the pulleys on the drum-shafts and counter-shaft brought into play for these purposes; and it will alsobe seen that the filling operation, which is effected entirely by the winding of. the length of cable cexteuding ed he ingly slow.

While the several operations are described an operator will readily become sufficiently expert to perform simulraneousl y those that are intended to be so performed.

It will be-obser'ved that, inasmuch 'as-the scraper is conveyed by the carriage I on the cable c as it ascendsand descends, the advanrage ensues of the employment of the gravity of the scraper in traveling by reason of the center of gravity changing with the rise and fall of the front pulleyg. -This function of the pulley g'is, however, not vitally important in my improvement, as the power f r producing the hoisting and traveling operations ofthe scraper maybe applieddirectly over a pulley g, it stationaryu i v For some classes of work, as in removing mounds, where'the track cannot be laid on the top of them, in banki-ng railways, and the like, the scraper requires to be operated for filling in the contrary direction to that described, when the cable (2 on'the drum E would be accordingly reversed and the scraper It should be mentioned {that instead of em- -ploying a boom B, the cables can be suspended at a point as far away from the windi ng mechanism and as high as may be desired;

and the anchorage may be a movable tower.

In the latter case the apparatus isespecially serviceable as a mere, conveyor, the carriage I then serving'as a medium for supportingany suitable form of receptacle or holder.
