Be it known that I, RAY J HELLER, citizen of the United States, res ding at Lan- Ingham. and State of useful Improvements in Earth Scrapers, of

. which the following is a specification.

This invention relates to earth. scrapers, .for road work or excavations or the lrke and "has for its object the production of .a scoop or shovel body intended to be drawn along by horses or tractor force,and having parts of special construction and arrangement comprising a plurality of scraper bladesof which at least one is adjustable with respect to the side walls, and having a top extend- .ing between the sides. It is believed that by he combination of a number of scraper blades, one in advance of another, and adjustable one with respect to another, packed weight or denby having a top plate or member of suitable size and location, when the scraper becomes filled it will tilt up and cease its digging action instead of merely continuing and overflowing.

In the accompanying drawings the particular formation and disposition of the parts .are illustrated, and Fig. .1 represents a view from the front andin perspective of the usual form of this invention, showing all ,parts assembled. Fig. 2 is .a view from the front and in perspective of an important modified form of this invention showving the'individualor smaller scraper blades arranged at the sides. All parts are shown assembled "n this view. Fig. 3 is an inside view of the lower front corner portion of one side, and shows the auxiliary scraper blade pivotally connected with the side in such manner that when the scraper is drawn forward the blade will excavate, but when the scraper is drawn backward the blade will lift.

The angle irons and bolts used are the. same as already described, and are of common form and operation. In the modification the vertical rows of holes near the edges of the sides for engagement with the draught appliances are designated P, and the horizontal rows of holes Q are provided as before for the hoist connections.

lowerforward corner of a side R. There are inclined rows .of holes 9 for the adjustment of the auxiliary blade carrier or angle iron The blade itself is marked T, and below it will be noted the stop bolt t. WVhenthe blade T is pivoted in one of the holes 1* of an upper row of holes, the stop bolt may engage one of the lower holes. While it is occasionally of advantage to pivot the scraper blades, or the scraper as a whole, this invention is in no sense limited thereto or to any special devices for attaining that In the operation of this invention under what may be regarded as one of the natural con itions met with, let it be assumed that a gravel bank is to be excavated, and. that the material is somewhat dense and heavy. It

- is believed to be readily discernible from the auxiliary or advanced a higher level between off the top layer or stratum of the gravel deposit, and the following main scraper blade will take up another layer, rendering the operation of taking up the whole scraper load much easier and consequently more rapid. The operation of the modification is the same, and the individual auxiliary scraper blades efiectively loosen the top of the sand or gravel body for the action of the main scraper following. Oftentimes it is necessary to draw the scraper directly backward on the ground, and to avoid the retardation and dragging effect of the scrapers they may be pivoted as illustrated in Fig. 3. l/Vhen so attached the scrapers will dig when drawn forward, but will lift and slide over the earth when drawn backward.

Having now described this invention, and explained the mode of its operation, what I claim is 1. In a scraper, the combination with the drawings that the scraper beingset at the sides will take sides, of a top plate connecting the sides, a

back plate connecting the sides, a downwardly inclined scraper bladesecured to the sides adjacent to the back plate, the said top plate extending over the said blade in a forwardly direction for a distance substantially equal to the extent of the said blade in the same direction, and an auxiliary blade mounted in an inclined position in advance of the first mentioned blade.

2. In a scraper, the combination with the sides, of a top plate connecting the sides, a back plate connecting the sides, a. down wardly inclined scraper blade secured to the sides adjacent to the back plate, the said top plate extending over the said blade for a distance substantially equal to the extent of the said blade in the same direction, an auxiliary blade mounted in an inclined position in advance of the first mentioned blade, and the said sides having a vertical row of holes whereby the draft cable may be attached higher or lower with respect to the said blades.

3. In a scraper, the combination with the sides, of a top plate connecting th: sides, a back plate connecting the sides, a downwardly inclined scraper blade secured to the sides adjacent to the back plate, the said top plate extending over the said blade for a distance substantially equal to the extent of the said blade in the same direction, an auxiliary blade mounted in an inclined position in advance of the blade first mentioned, and means for adjusting the auxiliary blade in position.

4. In a scraper, the combination with the sides, of a top plate connecting the sides, a back plate connecting the sides, a downwardly inclined scraper blade secured to the sides adjacent to the back plate, the said top plate extending over the said blade, an auxiliary blade mounted in an inclined position in advance of the blade first mentioned, and means for adjusting the auxiliary blade in a higher or lower position and in a forward or rearward position with respect to the back plate.

In testimony whereof I afiix my signature.
