Lette/rs Patent No. 88,686, lated April/SGIL IMPRovED ROTARY ROAD-seRr-ERL The Schedule referred to in these Letters Patent and making part of the same.

To all whom 'it may come/m Be it known that I, J AcoB W. WILSON, of Somerford, in the county of Madison, and State of Ohio, have invented new and useful Improvements in Rotary Road-Scrapers and I do hereby declare that the following is a full, clear, and exact description of my invention, reference being had to the accompanying drawings, forming a part of this specification, and to the letters of reference marked thereon, of which drawings- Figure 1 is an elevation of my improved scraper.

Figure 2 is a plan of the same.

Figure 3 is an elevation of the same when in position for levelling down earth.

Phe nature of my invention consists in the novel construction and arrangement of the mechanism used in combination with a road-scraper, for the purpose of operating the same, whereby I am enabled to regulate the4 depth to which the scraper i s. tocnt into the earth to be scraped, to hold the scraper in a proper position for transporting the earth scraped up, to hold the scraper in a suitable position for levelling down the earth after it is scraped to 'the desired position, and tol readily revolve the scraper, so as to discharge its load, and get it in position for anew one, or to perform any service that may be required of the scraper, with but very little muscular exertion, and in a very effectual manner, the whole machine being of simple construction, and moderate cost, and not liable to get out of repair.

To' enable others skilled in the art to make and use my invention, I will proceed to describe itsconstructiou and operation.

The scraper A is of an ordinary form, and, as represented in drawing, is made with bottom, D, with sharp front edge, sides C C, and rear-end piece B, the several parts being arranged as shown, but an ordinary cast-iron scraper may be used, if' preferred.

lo the sides O O of the scraper' A are secured the standards E E, which have pivot-bolts in their ends which pass through holes in the tongue-pieces I I, which are secured ou them by means of the nuts e e, as shown.

The tongue-pieces I I are bent into the form shown, and are secured to the tongue J by two or more bolts, aa, as shown, said tongue ,serving as a means of attaching the team to the machine.

The handlesF F are united at their rear ends by 'the cross-bar G, and are braced by braces ff inserted in the angles, between the cross-bar and handles, as shown.

The front ends of these handles F F are pivotedby bolts c c to the tongue-pieces I I, at points near the inward bends in said irons, as shown.

These bolts'c c pass through holes in the pieces F F and I I, and through the washers b l), which are-placed between the tongue-pieces and handles, as shown, to prevent any rubbing between them.

To these handles F F are secured the irons K K, by means of thescrews or bolts It lo, as shown.

These irons K K are of an L-shaped cross-section, and are so arranged on the handles F as to leave a slot between the arm of' the L and the lower face of the handle F, as seen in detached cross-section in fig. 3.

The bolts, or pins L L are secured in the sides O O of the scraper A in such a manner as, that when the scraper is at work scraping or transporting earth, their ends slide in the slots between the ironsK K and han- 4dles F F, as seen in figs. 1 and 2.

The spikes, or pins H H are inserted in the upper edge of the rear piece B of the scraper A and The pins M M are inserted in the lower faces ofthe ,handles F F, as shown.

The operation of'my improved scraper is as follows:

The motive-power being secured to the tongue J, the handles F F are pressed down by the operator, who graspsthecrossrbar Q, and this presses ,down on the pins L L, which depresses the rear part, and of course elevates the sharp -front edge ofthe scraper A, so-that it can be drawn to the desired location for working.

When the scraper is to be loaded, the handles F F are raised by the operator, which causes the front of the scraper to dip into the, earthfthrcugh the action `of the irons K K, on the pieces L L, in a .manner readily seen, and the dip of the scraper, while being loaded, is easily regulated by raising or lowering the handles F F.

When the load is obtained, the handlesD F F are pressed down, as before described, and the load is then drawn to any desired place.'

When the scraper is to be unloaded, the operator raises the handles F F until the front o" the scraper A catches in the ground, and thus tilts the scraper up in the position shown in fig. 3.

The pins L L then strike against the pins M M, in the handles F F, and thus hold the scraper in the position shown in fig. 3, when it can be used to level oli' the earth, which it has thrown in a heap, as is readily seen.

After this levelling oi is finished, the operator raises the handles F F until the pins L L slip under the pins M M, when the scraper A falls forward, and the pins H H stick in the ground, when it is readily seen that the forward movement of the team will cause the scraper to make another half revolution, and thus come back to its original position.

As soon as the operator hasraised the handles F F su-iieiently to let the pins L L pass under the pins M M, he releases said handles, which then drop down on to he standards E E, as shown by dotted lines K F, in g. 3.

The pin L describes the arc of a circle, (represented by circular dotted lines in iig. 3,) during the revolution of the scraper A, so that when the scraper comes back into the position shown in g. l, said pins L L come back to their original positions in the slots, between the handles F F and irons K K, when it is readily seen that the scraper can again be operated, as .before shown. A

It is readily seen that Where there is no occasion for the scraper acting as a leveller for its ownload, the operator, when desiring to unload the scraper, will first raisethe handles F F, until the scraper is tilted up, then,'as soon as the pins L L pass out from the .irons K K, he will raise the handles F F enough to allow the pins L L to pass under the pins MM, when the scraper A will turn over at once, as is readily seen.

Having thus fully described my invention,

What I claim las new. and desire to secure by Letters Patent, is

1. The peculiar arrangement and combination of the scraper A, standards E E, tongue-pieces I I, and handles F F, the several parts being arranged substantially in the manner and for the purpose-specified.

2. The L-shaped ironsKK, when used in combination with the handles F F and the pins L L, on the scraper A, substantially as and for the purpose specified.

3. The pins M M, when usedin combination with the handles F F, pivoted to the tongue-piecesI I, and

eases pins L L, and the scraper A, substantially as and for the purpose herein specified.

4. rIhe peculiar arrangement and combination of the scraper A with standards E E and pins L L, the tonguepieces I I and handlesF F, with pins M M, and l -shaped irons K K, the several parts being arranged substantiallyin the manner and for the purpose herein specied.

-5. The rotary road-scraper, herein described, conlposed essentially of the scraper A, with standards E E, pins L L, and spikes H I-I, screwed thereto; the tongue-pieces I I, with tongue J, the pivot-bolts c c, with separating washers b b; handles F F, with pins M M, andl L-shaped irons K K, and cross-bar G, with braces ff, the several parts being constructed and arranged substantially in the manner and for the purposes herein specified.

As evidence that I claim the foregoing, I have hereunto set my hand, in the presence of two Witnesses, this 23d day of November, A. D. 1868.

JACOB W. WILSON.
