WHEELED SCRAPER.

PECIFICATION forming part of Letters Patent No. 380,314, dated April 3, 1888.

(No model.)

T0 @ZZ whom it may concern:

Be it known that l, PATRICK DEnvY, a citizen of the United Sta-tes, residing at Hastings, in the county of Adams and State of Nebraska, have invented a new and useful Improvement in Wheeled Scrapers, of which the following is a specification.

My invention relates to an improvement in wheeled scrapers; and it consists in the peculiar construction and arrangement of devices, that will be more fully set forth hereinafter,and particularly poi nted outin theclaims.

My invention is an improvement upon the wheeled scraper for which Letters Patent of the United States, No. 364,493, were granted to me June 7, 1887.

In the accompanying drawings, Figure 1 is a side elevation of a wheeled scraper embodying my improvements. Fig. 2 is a similar View of the same, showing its operating parts in another position. Fig. 8 is a top pian View. Figs. 4 and 5 are detail views.

A represents the scoop or bowl, which is preferably rectangular in shape, as here shown, having the vertical sides B and the vertical rear wall, C. The front edge of the bottom of the scraper and the front edges of the wallsB are sharpened to adapt them to cut through earth, and the front edges of the side walls, B, are also inclined rearwardly, as shown. Fr om the sides B, near the centers thereof, extend a pair of vertical standards, D, which rise to a suitable height above the scoop. ln the upper ends of these standards is journaled an axle, E, which is provided with downwardlyextending cranks F, arranged in line with each other and having spindles at their lower ends, on which the wheels G are journaled. From the rear sides of the standards D project outwardly'extending stops or catches H, which are adapted to bear against the rear sides of the cranks F. From the rear side of the scraper projects a slotted arm, I, in which is pivoted a latch, K. The upper end of the said latch is provided with a rearwardlyextending bar, and from the lower end thereof` extends a horizontal arm, L. The front end of this arm bears against the rear side of the scoop when the latch is in a vertical position. On the sides of the scoop are secured the usual rearwardlyextending arms, M.

N represents a pai r of brackets, one of which is attached to the outer side of each of the sides B of the scraper at a suitable distance from the front edge thereof.

O represents a Ushaped yoke, having the forwardly-extending arms P on opposite sides or" the scraper and the cross-bar B behind the same. The front ends of the arms P are pivoted to the brackets N, the said arms P being provided with a series of openings, S,whereby they may be adjustably connected to the scraper. At a suitable distance in rear of the series of openings S are a similar series of openings, T. U represents a pair of links, which are pivoted to the lower ends of the axle-cranks F and have their lower ends working in vertical slots in the arms P. Bolts W extend through either of the series of open ings T and through openings in the lower ends of the links U, and thereby serve to adj nstabl y connect the lower ends of the said links to the said arms.

,X represents stops or detente, one of which is provided for each arm P,near the front end thereof. The said stops or detents extend upward and rearward from the said arms, and have their upper ends bent inward at right angles, as shown. These stops or detents may be either formed separately from the arms P and bolted thereto, as shown, or they may be formed integrally with the said arms, as l do not limit myself in this particular. From the rear side of the cross-bar B of the yoke, at the center thereof, extends a rearwardlyprojecting lever, W, the rear end of which is curved upward, as shown.

On opposite sides of the scoop, at a slight distance in rear of the brackets N, are secured ears Y, to which are pivoted the ends of a U-shaped frame, Z. A tongue, A', is rigidly attached to the central portion of the said frame and projects forward therefrom. points at which the rear ends of the arms of the frame Z are pivoted to the scraper are nearly on a level with the top edges of the said scraper.

B represents a vertical arm which extends upward from the frame Z, and to the said arm is pivoted a catch, C.

The operation of my invention is as follows: The machine is in its normal or initial position when the scraper is elevated a slight distance above the earth and is in a horizontal The ICO

position, as shown in Fig. 1. When thus arl ranged, the catch K is engaged with the cr0ssbar of the yoke P, and the catch O is disengaged from the said yoke and is supported in an elevated position. In order to cause the scoop to bite into the earth, and thereby bet come filled with material as it is drawn forward, the catch Xis disengaged from the yoke P, and the latter is turned upward to the position indicated by dotted lines in Fig. 1, thereby causing the links U, which connect the arms of the said yoke to the cranks of the axle, to turn the latter so as to raise the supporting- Wheels above the level of the bottom of the scoop. Vhen the yoke is turned upward far enough to cause the scoop to be arranged at such an angle as will readily enable it to become filled with material, the detents X bear against the upper sides ofthe rearward-extending arms of the frame Z, and thereby maintain the scoop in the said inclined position, the forward draft of the machine preventing the scoop from turning down while being filled. In order to carry the load to its place of deposit, the yoke P is turned toits initial position (shown in solid lines in Fig. l) by bearing downward on the lever W until the latch or catch K automatically engages the said yoke P, and inl order, then, to dump the load and secure the scoop in position, the operator then grasps the lever W and tilts the scoop to the position indicated in Fig. 2, at which point the yoke P becomes automatically engaged by the catch C', thereby holding the scoop in its position. When in this position, the machine may be readily drawn from one place to another, as will be readily understood.

If it is merely desired to dump the scoop of its contents, the same will not be turned quite so far as to cause the yoke to become engaged by the catch .0.

Having thus described my invention, I clain1- 1. The combination, with the cranked axle, of the scraper pivotally hung thereon, the draft-frame pivotally secured to the sides of the scoop, the rearwardly-extending yoke pivoted to the sides of the scoop below and in advance of the pivotal point of the draft-frame and connected to the cranked axle, the arm B', rising from the draft-frame, and the catch C', pivoted to said arm and adapted to engage said yoke, as set forth.

2. The combination of the cranked axle, the scoop hung thereon, the draft-frame pivoted to the scoop, the rearwardly-extending yoke, also pivoted to the scoop, the slotted arm extending rearwardly from the scoop, and the catch pivoted in said arm and engaging the scoop at its lower end and the yoke at its upper end, substantially as specified. l

3. The combination of the scoop having the vertical standards D, the cranked axle journaled to the said standards and having the supporting-wheels, the draft-frame having lts arms pivoted to the sides of the scoop, the yoke P, having its arms pivoted to the sides of the scoop at points below and in advance of the pivotal connections of the draft-frame, the said yoke P being further provided wlth the detents X, adapted to engage the draft-frame, for the purpose set forth, and the links U, connecting the said yoke to the cranks of the axle, substantially as described.

4. The combination of the scraper or scoop, the draft-frame pivotally connected thereto, the cranked axle from which the scoop is suspended and having supportingwheels, the yoke P, extending rearward from the sc oop and having its side arms pivoted to the sides of the scoop and longitudinally adjustable thereon, the said yoke being further provided with the detents X, for the purpose set forth, and the links U, pivoted to the lower ends of the crank-arms of the axle, and having their lower ends pivoted to the side arms of the yoke P and longitudinally adj ustable thereon, substantially as described.

5. In combination with the scraper or scoop, the cranked axle from which the scraper or scoop is pivotally hung, the draft-frame pivotally attached to the scoop, and theyoke P, pivotally attached to thc scoop or scraper and having the arms or detents X to engage the draft frame and lock the scraper or scoop when the latter is swung to an inclined position, as set forth.

In testimony that I claim the foregoing as my i own I have hereto affixed my signature in presence of two witnesses.

PATRICK DEEVY.
