IMPROVEMENT IN ROAD-SCRAPERS.

Specification forming part of Letters Patent-Xo. 125,025, dated .Iarcli 2G, 1872. i

Specification describing certaill Improvements in Road-Scrapers, invented by ELIIIU F. CCY, ot' Longview, in the county ot' Upsliur and State ot Texas.

This invention relates to that class ot' road or earth scrapers which are mounted upon carriages for greater facility in moviilg the loaded scoop to the duiiipillg place and back again. M y improvement consists in hanging the scoop to the carrizlge iii such a lnaiiiier that it may always he iliade to scrape in horizolital planes whether the carriage riiii on a level sul'l'ace or on a hill side; and also in certain devices for holdilig the scoop sllspended above the ground while ins ieg from place to place.

Figure 1 illustrates, in perspective, illy iinproved road-scraper with the scoop held suspended above the ground. Figs. 2, 3, 4, aild 5 are side elevations, the near wheel ot' the car riage beilig removed, showing the scoop in` various positions.

'lhe saiile letters of reference are employed in all the figures in the desi giiatioil ot' identical parts.

The axle A is bent up between the wheels B B of the carriage, in the lliailner best seeli in Fig. 1, so as to at'ord suieient space in a vertical direction to the scoop C to revolve it. The scoop turns on horizontal journals cc, coilnectiilg it with the lialidles D D aiid the ends ot' the curved draft-rod E; the journals beilig located rather nearer to the rear end ofthe scoop, so that its natural tendency will be to tilt forward whether loaded or not. 'llie curved draft-rod E is attached by means of a short chain, E', to the bolt F1, depending from the tongue F, and carrying the double-tree F2. y This bolt is also embraced by the eye in the curved rod F3, the ends of which are attached to the axle near the wheels, and froni which suitable braces extend to the tongue. .The journals c c protrude beyond the draft-rod and handles of the scoop, and pass through eyes in the ends of the bail Gr, which straddles the tongue F, alid is coliliected by means of a thain, G', to the short arm of a lever, H,ftilrning upon a, pin, h, in the standard H1, which is secured to the axle ofthe carriage and suitably braced. When the scoop is to be held suspended above the Y round the long arm ot' the leverv H is depressed and 'ho ked under the hook H2, and

when thus suspended the scoop with its handles is prevented froni tilting up at the` rear end by means ot' a dog, I', which, when tiirlied down, as shown iii Figs. 1 aiid 3, contines the bar D" of the .ialldlcs, clamping it to the crossbar of the frame I. 'Lhelat-ter is, at its upper end, secured to the rear elid of the tongue F, and, projecting downward, receives between it the bar D', which extends longitudinally from one crossebar to the other of the handles. The dog I is bent into the forni best seen in Fig. 1, pivoted to the cross-bar 1', aiid prevented from turning down beyond the point desired by another cross-;; r, i. By suspending the scoop in the nianner above set forth it is caused to assume a horizontal position whether the carriage runs on a. level or all inclined surface. The scoop is locked to the handles by means ot aspi'ing, a, and catch b on cach side, preventing its heilig tillned down at the rear end, aild a spring-bolt, d, and catch c on the rear end, so arranged that whei the bolt is projected above the catch it holds the scoo against bein g tilted at the forward elld. \Vlien it is desired to discharge the loud the springbolt is retracted by means of a 10rd, f, when the scoop will turn forward. Assuming the `position shown in Fig. 5, the spurs g g strike into the ground, holding.1r the scoop aiid causing it to again turn right side up as the carriage is drawn forward, aiid become locked to the lialidles, ready for another operation. The length of the bail G aiid cllaiii G is such that when the lever H is released from the hook H2 to lower the scoop into position for scraping, the weight of the scoop will bc carried by the carriage, and the scoop prevented from` dragging while it is scraping.

XVhat I clainl as inyinveution, and desire tov secure by Letters Patent, is Y 1. The scoop C attached to the draft-bolt. F1 by a chain or its equivalent, in coinbination with bail G, chain G', and lever H, subA stantially as specified. Y

2. The combination of the bar D ot' the handles of the scoop, fraine I, alid dog I,*sub stantially as and for the purpose set forth.

Intestiinony whereof I have signed lnynaine to this specification in the. presence ot' two subA scrihing witnesses.
