GEORGE J. WEBER, OF BOONVILLE, MISSOURI.

WHEELED SCRAPER.

SPECIFICATION formingpart of Letters Patent No. 245,898, dated August 16, 1881.

Application filed January 31, 1881.

To all whom it may concern Be, it known that I, GEORGE J. WEBER, a citizen of the United States, residing at Boonville, in the county of Cooper and State of Missouri,haveinvented Improvementsin Wheeled Scrapers, of which the following is a specification.

The machine consists of a scoop or scraper of any suitable form, having near its front end hangers pivoted to arms projecting from a curved axle-beam, and capable of being connected or disconnected in the rear at will, by means of a hook extending from the back of the scoop, and a gravitating loop pivoted to a hand-lever projecting rearwardly from said axle-beam. beam are two detachable gudgeons upon which rotate the two supporting-wheels. The apparatus is provided with a tongue to which are attached two draw-bars pivoted to the sides of the scoop, near its front, at the base of the aforesaid hangers, and having upon their rear ends lugs or stops, which, impinging against the back of the hangers, prevent the scoop from tilting backward beyond a certain limit.

, Attached rigidly to the tongue is an upwardlyprojecting spring-arm, having near its upper end an eye in which a pin on the hand-lever automatically engages when the scoop is inverted, so as to hold the scoop in that position, if desired, until it is to be refilled, when it may be released by a pull sidewise upon the springarm. Inside the scoop is a rectangular plate pivoted at its back corners to the sides of the scoop, and capable of being operated at will by a lever outside the scoop, the object being to assist the team in filling the scoop and compressing the earth, and also to prevent the earth from falling out during transportation. A catch or projection on the side of the scoop holds the said lever in its depressed position. Besides the hand-lever referred to, two handles, one on each side of the scoop, are provided, which are also used in operating the scraper. Secured to the under side of the scoop are too runners of I-shaped cross-section, which are cast with a chilled base and riveted to the scoop by their upper flanges, thus making no obstruction on the wearing-surface, and also preventing the rivets being worn off by abrading sand, gravel, &c.

Extending laterally from the axle (No model.)

In order that my invention may be fully understood, I will proceed to describe the same with reference to the accompanying drawings, in which- Figure l is a perspective view of a wheeled scraper embodying myimprovements. Fig. 2 is a side elevation of the same, showing the scoop in its inverted position. Fig. 3 is a perspective view of one of the runners. Fig. 4. is a perspective view of part of the scoop, showing the hinged plate. Fig. 5 is a perspective view of one of the gudgeons detached.

A A are two ground-wheels supporting the axle beam or yoke B and the apparatus hung thereto, by means of detachable gudgeons C O, that being partly embedded in the frame B are secured thereto by U-shaped clamps D and nuts-d.

The object of making the gudgeons detachable is to enable the changing of the machine from a wheeled to a sliding scraper by removing the gudgeons and wheels, which may be done by simply unscrewing the nuts (I d and slipping out the clamps D D.

The two arms E E of the yoke B extend forward of the gudgeons to apoint, e, immedi ately over the couplingFof the tongue or drawbars G G to the scoop H, at which point ethey are pivoted to hangers I I, that extend downward therefrom tothe aforesaid coupling, F, and then upward again on the inside of said tongue-bar, where they are firmly secured by rivets or bolts t t to the sides of the scoop H.

The axle beam or yoke Bis curved backward from the gudgeons, and to its middle portion is rigidly secured a hand-lever, J, that extends sufficiently to the rear to give the desired leverage. Pivoted to this hand-lever, at It, is a gravitating loop or dog, K, adapted to engage under a beveled hook, L, on the back of the scoop. An arm, 70, on the loopK enables the operator to release the same from the hook L when it is desired to lower the scoop to the ground.

The tongue-bars G G converge toward and are attached to the tongue M at m at which point also is attached an L-shaped arm, N, that extends upward and slightly backward, and is provided near its upper end with an eye, a, and handle a. When the scoop is inverted, and the hand-lever J shoved forward as far as possible, a pin or stud, O, on said hand-lever, sliding along the inclined surface a, immediately above the eye it, and thereby pushing slightly to one sidethe arm N, (which is made with sufficient springfor the purpose,) engages within said eye, and thus holds the scoop in its inverted position, as shown in Fig. 2.

It will be observed'that, owing to the loopform of hangers I I and curved shape of the axle-beam B, the tongue-bars G G are free to turn on pivots F F into a position back of the gudgeons O (J, as shown in Fig. 2.. The rear ends of the tongue-bars GG extend upward from the coupling-pivots F I, as at It, and at the extremities of such extensions are lugs or stops 1', which, by impinging against the back of the hangers I I, serve to prevent the scoop tilting backward when loaded.

In the inside of the scoop is a plate, P, pivoted at p p to the sides of the scoop and having a lever or levers, Q, rigidly attached to one or both of its pivots. The use of this plate is to assist in the loading of the scoop when in its depressed position and to prevent the earth from falling out during transportation when elevated by depressing the lever Q. A beveled-catch or hook, S, on the side of the scoop beneath which the lever may be forced, serves to hold said leverin its depressed position.

On each side of the scoop are rigidly attached handles or arms T, used in guiding the scoop into and outof the ground. These handles pass through the back of the scoop and at their forward ends are riveted or bolted to the backwardlyprojecting arms I I of the hangers I I.

Riveted or bolted to the under side of the scoop are two cast runners, U, of I-shaped cross-section, which have their lower flanges, u, chill-hardened, and through whose upper flanges, a, pass the rivers or bolts h. The lower flanges, u, are curved upwardly in front to meet the bottom of the scoop, as shown. By this construction of runner none of the rivets or bolts form any part of the abrading or sliding surface, and hence the said surface remains smooth and unbroken.

The scraper is operated as follows: The operator, releasing the dog K, allows the scoop to gouge into the earth until nearly filled; then, pushing downward on lever Q, the earth is thrown into the back of the scoop, the power of the team assisting in the operation by causing the earth in front of the plate to press the same backward; then, depressing the hand-lever J, the dog K engages automatically under the hook L, and the load, being then supported wholly upon the wheels, may

be transported to its destination without un necessary loss of power. In order to dump the load the operator throws the hand-lever J forward a sufficient distance to invertthe scoop and thus discharge it. By shoving the lever forward until the pin 0 engages in the eye a the scoop will be held securely in its inverted position, and may remain so during transportation. The plate P, which remains depressed while the scoop is filling, is tipped up when the scoop is full in order to prevent any earth falling out. For thispurpose theleverQ is pushed down below catch S, from which it is again released when the load is to be discharged.

I am aware that it is not new to construct vehicles with detachable gudgeons, and such I do not wish to claim 1901* 80, as my invention in this particular consists in adapting a scraper to be readily converted into either a wheeled or sliding scraper at will.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. The combination, with the scraper-bod y, of the axle'beam B and detachable gudgeons 0 O, the latter secured to the former, as set forth.

2. The combination, in a wheeled scraper, of the curved axle-beam B, hand-lever J, and hangers I I for raising, lowering, and supporting the front part of the scoop.

3. The combination, in a wheeled scraper, of the hand-lever J, axle-beam B, with the dog K, hook L, and hangers I I, substantially as and for the purpose set forth.

4. In a wheeled scraper, the combination of the curved axle-beam B and looped hangers I I, pivoted thereto, with the tongue M and tongue-bars G G, pivoted at the lower end of said hangers, operating as set forth.

5. In a wheeled scraper, the gravitation-loop K, pivoted to the supporting-frame and having arm in combination with beveled-hook L on the scoop, for the purposes set forth.

6. The combination of looped hangers I I and pivoted tongue-bars G G, having stops 7', all operating as and for the purpose set forth.

7. The hinged plate I? and its operatinglever Q, in combination with catch S, as and for the purpose set forth.

8. The cast runners U, of I-shaped cross-section, as and for the purpose set forth.

9. The combination of the handles T, passing through the back of the scoop and secured at their forward ends to the backwardlyprojecting arms I I, of the hangers I I, as and for the purpose set forth.
