Wl-i EELED DUMPlNG-SCRAP ER.

SPECIFICATION forming part of Letters Patent No. 390,374. dated October 2, 1888.

(No model.)

To all whom, it may concern.-

Be it known that I, GYRUs A. KENNEY, of Nicholasville, in they county of Jessamineand State of Kentucky, have invented a new and Improved Wheeled Dumping Scraper, of which the following is a full, clear, and exact description.

The present invention relates to a scoop or scraper which is supported on wheels, and is adapted to be lowered to presentits scoopingedge to the ground for filling, for being raised to a greater or less height, and to be dumped backwardly; and it consists in a combination of the mechanisms and of the constructions and combination ofparts thereof,substantially as will hereinafter more fully appear, and be pointed out in the claims.

Reference is to be had to the accompanying drawiugsfiormingapartofthis specification,in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a side elevation of the wheeled scoop, showing the scoop-body as raised with its rear end closed for carrying the load, and bydotted lines its position for dumping, with the tail'board or rear gate as held in its opened position. Fig. 2 is a rear elevation ofthe same, with parts at one side broken away the better to illustrate the construction of the scoop-elevating drum-shaft clutching mechanism, the clutches thereof being shown as disengaged. Fig. 3 isa central longitudinal section through the same on line so or of Fig. 2, but with the scraper-body as dropped into its position for scooping; and Fig. 4, sheet 2, is a view in rear elevation illustrating the changed position of some of the parts for shifting the clutching mechanism.

The wheels A. A are mounted on the outwardlyprojecting axles B at the lower end of standards 0 G of an arch-frame formed by said standards and a crossbar, O and said standards are provided on their inner sides with flanges or ways D, upon which flanged rollers F carried by the guiding and embracing arms or clasps E of asupporting-framc, F, run,said supporting-frame consisting of side bars, F and a cross-brace, F, held above the horizontal line of the side bars, F, by uprights F*, said side bars, F, having extending downwardly from an intermediate portion at each side thereof rigid arms F, to which the scoop or scraperbody G is pivotally hung forward of the center,asbyits trunnions G,passingloosely through said arms F, and provided with suit able retaining shoulders or collars, said scoopbody consisting of bottom G, with forward edge suitably beveled for taking to the ground, sides G formed integral with the bottom, and opening and closing rear gate or tail-board, G; and from the ends of a crossbrace, H, of the tongue H or thills are rearwardly-extending draft-bars H, passing through vertical guiding-slots in vertical bars F, extending from and above the side bars, F and pivoted at a point, I), of said scoop frame bars F in advance of the central portion of the scoop-body, said bars H continuing forward inwardly until theyjoin and are secured to the tongue H and from a forward portion of the tongue to the central portion of the crossbar (l of the axle-arch is extended a brace-plank, 11*, se cured at its forward end to said tongue by a headed screw or bolt, f, passing through a shoe, H of the brace-plank and to the said crossbar G by car-pieces H, pivoted to lugs G of said cross-bar, and thus when the scoopframe is suspended in either its raised or lowered position from parts on. the axlearch uprights, as hereinafter described, said uprights are by said brace-plank always held substantially at right angles to the tongue.

A transverse drum-shaft, K, is horizontally supported in suitablejournals, K, of the axlearch uprights, on which shaft the drums K are keyed or otherwise secured, each drum being provided with a ratchet-wheel, K formed thereon, as shown, or secured thereto, and to each drum K is fastened the end of a chain, K or other similar flexible connection, from the outer ends of which chains the scoopframe F is hung at g. A paw], m, is provided at each ratchet-wheel K, keyed upon a common horizontal pawl-shaft, an, rotatably supported on the front side of the axle-arch cross-bar G a radial lever-arm, m, with rearwardly-extended handle or, being provided for convenience in throwing said pawls out of engagement with their respective drum-ratchets, a coiled spring, m secured to a part of the pawl-shaft by one end and to a part of the axlearch by its outer end, retaining said pawls in their engagement with the ratchets K in a well-known manner. Near each end of the drum-shaft K is keyed a clutch-sleeve, K, with its clutch-teeth 19 toward the outer ends of said shaft, outside of which, playing loosely inwardly and out-wardly on the shaft, are clutchsleeves K, with clutch-teeth r toward the teeth of the clutches K, a spring, 70, between the inner face of a flange, Z, of the drum-shaft and the outer face of each sliding clutch-collar forcing said clutches K inwardly into engagement with the clutches K, except when forced outwardly, as will be explained hcreinafter.

Each moving clutch-sleeve K is provided with sprockets K driven by endless sprocketehains K from a sprocket-wheel,- A, on the hubs of wheels A.

There is pivoted to a projection, 12, of each upright O a vertically-extending arm, L, having a strap or yoke, L, loosely embracing the fixed clutch collar K and continued upwardly therefrom, terminating in about the horizon tal line of the top rear edge of cross-bar O, to the outer end, p, of which connectingrods L are pivoted, said connecting-rods extending inwardly therefrom and pivoted at eccentric points, as at p, of a disk, L, centrally pivoted to the rear side of the cross-bar 0', having an.

extended arm, L, for convenience in moving it, and its journal or pivot L has a radial or cranked arm, L, to the end of which one end of a spring, L is secured, which by its other end is fastened to a projection, q, of cross-bar G", the turning of said disk L through the connectingrods L carrying the ends 19 and yokes L" of arms L inwardly out ofbearing upon the overlying annular flange K of the moving clutch-collars K, permitting them, under the recoil of the spring is, to be thrown into engagement with the clutches K.

The vertical arms L are provided between their lower pivotal points and their yoke portions with inclined edges L projecting inwardly in a vertical plane intersected by that of the outer end of a projection, E", on the scoop-frame guidingclasp E, so that as the scoop-frame rises and forces the arms L outwardly the connecting'rods L partially rotate the disk L' sulficicntly to carry the radial arm L off the dead-center. (Indicated in Fig. 4.) The reaction of the spring L then secures such a farther rotation of the disk and projection of the connecting-rods that the clutches K are forced outwardly against their springs and there maintained by the excess of pressure of said spring L over the clutch-springs k.

When the clutches K are placed in engage ment with the drum-clutches by the turning of the lever-arm L therefor into the position shown in Fig. 4, to permit the clutches K under the reaction of their springs k, to slide into such engagement to secure, under the retation of the wheels through the sprocket-conv nections described, the rotation of the drumshaft and the winding of chains and raising of scoopframe and scoop, the said projections E of the rising scoop-frame F abut against said inclined edges L of the vertical lever-arms L, and said arms are thrown outwardly, their yoke portions forcing the movable clutches K outwardly against their springs 7c, and out of engagement with the clutches K, thus terminating the winding of chains K upon the drums and theraising of the scoop. Pressing downwardly on the outer end of the pawlshaft arm m releases the pawls from their ratchets and leaves the dru m-shaft free for the unwinding of the chains and descent of the scoop under its weight.

The rear gate, G, of the scoop body is hung by upwardly-extending armstthereof, pivoted, as at t, to the upper ends of arms 15*, extended above the scoop-sides G at the rear portions thereof, said gate by its ends 25 lying against the rear ends ofsaid sides, its bottom edge, 25', lying'slightly in advance of the rear end of the scoop-bottom G, and it is provided with a bolt, G, playing through sockets t, secured on the gate, having a lug, 1, against which a spring, t secured by its one portion to the gate, bears by its free end to force said bolt downwardly to project its lower end through a hole or socket, i, in the rear end of the scoop-bottom; and a chain, G, by its lower end secured to the lug t of said bolt, and its upper end to an upwardly and outwardly extended arni,ll ,ofthe crossbar F,serves, when the seoopbody is tipped backwardly on the trunnion G, to draw the bolt from the socket, and as the rear of the scoop tilts downwardly and inwardly, maintaining the lower end of the gate within the range of the chain, it is caused to swing upwardly from the pivotal point t on the arms t of the body as the body swings downwardly, as will readily be understood on reference to Fig. 1, where such tilted positions are illustrated in dotted lines. The arms t of the scoop-body are provided with angular-shaped dogs M, pi voted thereto, against the inner arms, M", of which springs 22 bear to project the arms M of said dogs forward to rest upon the top side of the scoop frame crossbar F, and through them the rear end of the body is supported; and a shaft, M, is hung above and parallel with said cross-bar F in lugs 12 thereof,having dogs M extending downwardly and rearwardly to lie near or against the arms M of the dogs M on the scoop-arms, a coiled spring, a, by one end secured to said dog-shaft and by its other end to the crossbar, maintaining said dogs M. to a bearing by their ends upon the cross-bar; but by partially rotating said shaft through its handle-lever M in a manner to swing the rear ends of said dogs outwardly and against the overlying and engaging ends of the dogs M of the body, the rear end of said body is released from its engagement with the cross-bar ofthe scoopt'rame and will, from the manner of its hanging and under its lead or its own weight, tip backwardly to dump.

N N represent shoes or runners upon the bottom of the scoop-body extending or incliir IIO esosw ing from their forward ends, a, which are substantlally flushvvith the under surface of the scoop-body downwardly, their rear ends be ing somewhat below said bottom. These shoes or runners may be rigidly attached to the bottom, or adjust-ably attached, as shown, by securing their said forward ends, a, thereto, and forming their rear ends with an inward and returning bend, through a slot in which a headed pin, 20, screwing in and out of the bottom, projects, by its end or head maintaining the rear ends of the runners outwardly, as de sired.

In the operation of the wheeled scoop, with the scoopbody suspended in its uppermost position by the chains from the drums, held from unwinding by the pawls, as seen in Figs. 1 and 2, and it is desired to scrape and scoop dirt, &c., by pressing downwardly on the pawlarm at the pawls are made to release the drum-ratchets, and said drums and their shafts are rotated under the unwinding of the chains supporting the scoop-frame, and from it the scoop-body, which descends to the ground, the inclining runners forcing the forward end of the scoop downward to take to the ground, too great a tip forward of the scoop being limited by the rear end of the body abutting against the crossbar F of the scoopframe; and when the tip of the scoop-body is adjusted by the runners for any depth of cut a pin should be passed through one of the holes 00 in the vertical guide-clasp bar F of the seoop-frame, through which the draft-irons pass, above such draft-irons, in a manner to prevent the forward end of the scoop being forced too deep into the soil by the suction caused by the resistance on the cutting edge,said cut ting-edge being below the line of draft. in other words, the lower the draft-irons are confined by said pin the lower the line of draft is brought, and the lower the line of draft the less suction-power there is to draw the cutting-edge into the ground. Then as the carriage with the scoop moves forward the latter fills, and on throwing the lcvenarm L of disk L over to draw the connecting-rods inward, and through them the sleeve surrounding the yoke of the arm L away from its bearing upon the overlying projection L of the cl utcheollar K, permitting said sprocketed clutch, under the action of its spring, to be thrown into engagement with the clutch K, which, causing the drum-shaft to rotate, winds up the chain and raises the scoop-body until such time as the clutches K are disengaged from the clutches K, which may be done at any time during the raising of the scoop by throwing the lever L back into its normal position shown, thus enabling it to be carried at any height, or when the scoopfralne rises to the height at which it is usual to carry the same, by its projection E abutting against the incline L on arm L, the clutches K are then automatically thrown out of engagement with the drunrshaft clutches and the winding discontinued. If desired, the inclined edge portion L of lever L may be adapted for bei ug adj ustabl y seen red thereon, whereby an automatic throwing off of the parts described for securing the winding up of the chains may be secured when the scoopbody has reached any desired height.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1.
