WHEELE'D SCRAPER.

SPECIFICATION forming part of Letters Patent No. 501,145, dated July 11, 1893. Application filed September 8, 1890. Serial No. 364,262. (No model.)

To all whom it may concern.-

Be it known that we, FERDINAND F. HUDEL and EDWARD H. LIEBENSTEIN, of the town of Lake,in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Wheeled Scrapers; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, and to the letters of refererence marked thereon, which form a part of this specification.

The main objects of our invention are to facilitate the operation of a scraper, to relieve the necks of the team from unnecessary weight, to utilize the draft of the team for 1 raising and dumping the scraper, and to enable one attendant to manage the team and operate the scraper.

It consists essentially of certain peculiarities of construction and arrangement hereinafter particularly described and pointed out in the claims.

In the accompanying drawings like letters designate the same parts in the several fig-- machine opposite to that shown in Fig. 1.

(the axle and the inner end of the hub of the front wheel being shown in vertical'section and the remainder of the wheel being removed, in Figs. 1, 3 and 4, and the entire front wheel being removed and the front end of the axle shown in cross-section, in Fig. 2). Fig. 5 is a plan view, and Fig. 6 is a detail on an enlarged scale of the locking device or clutch employed to lift and dump the scoop.

A represents the scoop, made of the usual or any suitable form, of sheet metal, and suspended by inverted V-shaped hangers B B, from the crank axle C, the hangers being bolted at their ends to the sides of the scoop, and formed at their angles with collars b b,

through which the crank c, of the axle C, loosely passes. At the ends of the crank arms 0 c the axle O is formed with journals upon which are mounted the supporting wheels D D.

-E E are draw bars pivoted to each side of the scoop A near its front end and extending therefrom forward parallel with each other, and then bent inwardly toward the pole F (a portion of which is shown in Fig. 5) towhich they are boltedor otherwise rigidly attached. For. the purpose of strength and stiffness these draw bars are preferably made double, as shown inFig. 5, the inwardly bent ends of the draw bars on each side of the machine diverging so as to separate the points of attachment thereof.

G represents a forked lever, the ends of which are pivoted to the sides of the scoop A near its front end and are connected a short distance from said pivot points, by jointed rods H, with the axle 0, just inside of the wheels D. One arm of the jointed connecting rod on each side of the machine is formed or provided with a projection h, which prevents the sections composing the rod from being drawn into the same straight line by the lowering of the lever G. The lower section of the connecting rod on each side is pivoted to the adjacent arm of lever G, and the upper section isformed with a collar h eucirclingthe axleO, which is capable of turning therein. The lever G is formed, when the scoop is elevated as shown in Figs. 2-and 4, to pass over and outside of its rear upper edge, and is provided at or near the center of its rear cross portion with a handle g.

To the outside of the arms of the lever G on both sides of the scoop are attached the forwardly projecting hooks g, so located and arranged as to pass over the axle O, a short distance inside of the hubs of the wheels D, when the scoop is raised into the position shown in Figs. 2 and 4, and to engage with said axle and thereby hold said scoop in its elevated carrying position until said hooks are disengaged, as, hereinafter described.

To prevent the scoop from falling back when it is being raised into a carrying position, shown in Figs. 2 and 4, we make one of the hooks 9, shown in Fig. 2, a little longer than the other shown in Fig. 4, so that the longer hook will engage with the axle C, before the crank arms 0 of the axle have arrived at a vertical position. These hooks g may be pivoted to the arms of lever G and provided with stops to limit their descent, or they may be rigidly attached to said lever in the required position to permit of their passing over and engaging with the axle C.

The inner ends of the hubs cl of the wheels D are notched, at intervals around their peripheries, and to the axle Cadjacent thereto are keyed orotherwise suitably fixed arms I 1, formed with sleeves i 11, transverse to the axes of and overhanging the notched peripheries of the hubs (Z.

J J are dogs or pins inserted and movable in said sleeves 'i, into and out of engagement with the notches in the hubs d.

To laterally projecting ears 2', formed on the arms I are pivoted the levers K K, which have curved arms k k, loosely passing through and engaging with perforations in the outer endsofthedogsJ. Theseleversarealsoformed or provided on the same side of their fulcrums with the slotted arms is, and on the opposite side of their fulcrums and approximately in line with the arms with arms 70 These arms 70' and k are bent inwardly at their ends, as shown in Fig. 5, toward the sides of the scoop, so as to engage, the arms 70 with stops on a, attached to the sides of the scoop when the latter is raised into carrying position, and the arms 7: with the stops 8 e, projecting outwardly from the draw bars E, when the scoop is turned into the position shown in Fig. 3, for dumping.

To the forward end of the scoop are attached on each side, stops a which engage with the draw bars E, when the scoop is elevated into the position shown in Fig. 2, thereby preventing the front end of the scoop from being tilted upward by the weight of its contents behind the axle upon which it is suspended. To the sides of the scoop are also attached stops a which when the scoop is raised into carrying position, as shown in Fig. 2, engage with the axle O and prevent said scoop from being carried farther forward.

L is a crank shaft supported parallel with the middle portion 0, of axle Gin bearings b, formed on or attached to one side of the collars b of the hangers B. To the ends of this shaft are fixed crank arms Z Z, having crank pins inserted in the slots formed in the arms 1 7c of levers K. At an intermediate point of the shaft L a curved arm Z is secured thereto, and counterbalanced by a similarly shaped weighted arm Z The arm Z is connected by a chain or cord m, with an L-shaped lever M, pivoted at its angle in the rear cross-portion of the lever G.

To hold the scoop at the proper angle in the ground, a guide Nis provided, consisting of a metallic plate attached at one end to the bottom of the scoop and extending outwardly and rearwardly therefrom and curved upwardly at the other end, which is vertically slotted and adjustably attached to the back of the scoop by a bolt 07., or other suitable means, as shown in Fig. 2 so as to permit of the variation of the angle formed by said guide with the bottom of the scoop.

Our improved device operates as follows: The scoop being lowered into the position shown in Fig.1,is caused by the guide Nand the advance of the scraper, to descend at its front edge into the earth and to take up a load, the scoop being guided, and the depth to which its front edge is allowed to descend, being controlled by the operator through the lever G and the jointed rods or links H connecting it with the. axle C. When filled, the operator depresses lever G, thereby lifting the front end of the scoop and at the same time moving the lower forwardly projecting arm of the lever M into engagement with the upper rear edge of the scoop, which throws the upwardly projecting arm of said lever to which the chain m is attached, rearwardly, thereby turning the crank shaftL and raising the arms 70' of levers K as indicated by dotted lines in Fig. 1 so as to move the. dogs J into engagement with notches in the hubs d of the supporting wheels D. The axle 0 being thus locked with the hubsof the wheels D, is turned upwardly, raising the scoop into the position in which it is shown in Fig. 2. The stops a engaging with the draw bars E, preventthe scoop from tipping rearwardly,and the stops a? engaging with the shoulders formed by the bends in the axle O, arrest the forward movement of the scoop. As the upper portion 0, of axle O, is turned forward by the continued advance of the scraper, the stops a a on the scoop, and the inturned ends of arms 70 70 approaching in a curve, indicated by dotted line in Fig. 1, engage with each other and automatically withdraw thedogs J out of engagement with the notched hubs cl of the supporting wheels. In this position, as shown in Fig. 2 the scoop with its contents is sustained and carried by the axle O and wheels D to any desired point to be dumped. As the. lovers K are turned on their fulcrums by engagement with stops on a, the inturned offsets of arms 70 70 describing curves similar to the shorter dotted arc in Fig.1, are moved out of engagement with said stops, passing underi neath them into the position shown in. Fig. 2. To dump the scrapeigthe operator pullsthe ichain m rearwardly and upwardly,thereby 1 throwing the arms 70' of levers K forward, and gmoving the dogs'J into engagement with the notched hubs d. The axle 0 being thus locked i with the wheels D, is turned forward, carry- ;ing the scoop into the position in which it is lshown in Fig. 3, for discharging its contents. 3 The inwardly projecting ends of thearms is ,engaging with the stops 6 on the draw. bars, automatically throw the clutches out of en- IIO gagement, thereby releasing the axle O and permitting it and the scoop to be returned to the positionsin whichthey are shown in Fig. 1.
