ROADHSCRAPER.

SPECIFICATION forming part of Letters Patent No. 398,581, dated February 26, 1889.

Application led September 24, 1888.

To all 'whom t may concern:

Be it kno'wn that I, ELIAS BURHANCE, a citif zen of the United States, residing at South Kent,in the county of Litchfield and State of Connecticut, have invented certain new and useful Improvements in Road-Scrapers; and I do hereby declare the following to be a full, clear, and exact description of the invention,

i l i i i l l such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to diggers and scrapcrs generally, but is more especially adapted to the class of scrapers used in building` and 1 novel construction ol' which the following dcscription, in connection with the accompany ing drawings, is a specification, numbers being used to denote the several parts.

Figure 1 is a plan view of the machine complete; Fig. 2, a side elevation as seen from the left, and Fig. 3 a side elevation as seen from the right.

l'denotes the framework, which preferably consists of two pieces only, lying at an acute angle to each other, as shown in Fig. 1. The parts of the framework are rigidly secured to the rear axle, 2, and to a block, 3, resting I i sition. The operator is thus given perfect on the front axle, 4.

5 denotes the scraper, which is ordinarily made of wood, and is provided at its lower edge with a cutting-blade, G, preferably7 made The scraper is supported at an oblique angle to the line of tra-vel of the machine by means of braces 7, three being ordinarily used, the front ends of which are pivoted to the scraper and the rear ends to the rear axle.

8 denotes an arm projecting' upward from the scraper, the upper end of which lies between diagonal braces 9, extending between the two parts of the frame-work, and islockcd in any desired position by means of pins l0, passing through both braces, a number of transverse holes being made through the Serial No. 286,280. (No model.)

braces, so that the scraper may be locked at any desired angle to the plane of the roadway. Should it be desired to have the scraper operate in a. plane vertical to the plane of the roadway, arm S is moved to a vertical position and locked there by means of pins l0. Should it be desired to have the scraper operate in a plane at a more or less acute angle to the plane of the roadway, arm S is moved backward and locked ai the desired position by the pins.

ll. denotes a cross-piece rigidly secured to the framework obliquely to the line of travel and approximately parallel with the scraper.

12 denotes levers pivoted to th scross-piece, and 13 rods connected to said levers and to the scraper near the ends thereof.

la denotes a platform at the rear end of the machine, upon which an operator stands and controls the action. of the scraper by means of levers l2. Should it be desired to raise the forward end of the scraper, the lever upon that side is raised. Should it be desired to raise the rear end of the scraper, it is accomplished by raising the other lever. The rear ends of the levers lie between pairs of up rights 15, and may belocked in any desiredV position by means of pins 1G, passing through the uprights between which the levers rest. It will thus be seen that the operator is able to adjust the angle at which the scraper acts at will, and to lock it in position, and also to adjust the height of either end of the scraper at will, or to raise the entire scraperby means of the levers and to lock it at any desired pocontrol of the scraper without stopping the machine, this being a very valuable feature, particularly where there are obstructions to the continuous operation of thc scraper in l any special position.

17 denotes a seat for the" driver, which is secured to the frame-work in any suitable manner; and 18, a footerest.

19 denotes the front wheels, and '20 the rear wheels. lt will be noticed in Fig. 1 that the rear axle is considerably longer than the front axle, and that the rear wheel corresponding with the rear end of the scraper tracks with the front wheel upon the same side. It will ot' course be apparent that in use the forward end of the scraper will produce something of a furrow-that is, there will be an abrupt ridge of earth left at its edge. It is an important feature of my invention that I place the rear wheel upon that side directlyin line with the I'orward end oli' the scraper, so that said rear wheel will track in the furrow made by the scraper, and will be supported by the shoulder or ridge ol' earth lel't just outside the line ot action of the scraper.

It will be understood by those familiar with this class of machines that in use the tendency is for the rear portion of-the machine to work inward, so that the earth collected by the scraper is not deposited at the desired position. lnorder to overcome this tendency as much as possible the machines have heretofore been made very heavy, thus greatly increasing` ythe draft and rendering it impossible for them to be operated to any extent by a single team. This objection is wholly overcome in my improved scraper by causing the rear wheel upon that side to track in the furrow left by the forward end of the scraper. The outer side of this wheel, thereto re, in pract-ice bears against the solid ridge ot' earth, so that the tendency to slide in that direction is wholly overcome and the earth collected by the scraper is deposited at just the desired position. This is a great saving in the bnilding of roads, as it avoids a repetition of operations to accomplish the dfsred result, while at the same time the draft ot the present machine is so much lighter than any heretofore produced capable of performing the same amount of work as to make a still more l l l i l, i' l l l important saving in the amount of draftpower required.

It should be understood that I do not limit my invention to the exact details of construction shown and described, as it is obvious that the details may be greatly varied without departing from the principle of my invention.

l claiml. The t1'aine-worl ,tl1e scraper placed obliqu'ely thereto, a front axle and wheels, and a rear axle and wheels, one rear wheel being in line with the corresponding front wheel and the other rear wheel in line with the forward end ofthe scraper, in combination with diagonal braces 9, an arm, 8, projecting` from the scraper, whereby the angle may be adjusted, and levers l2 and rods 18, connecting said le` vers with the opposite ends of the scraper, whereby either end may be raised or lowered.

2. The scraper having an arm, 8, the rear axle, and braces pivoted to the axle and to the scraper, whereby the latter is supported, in combination with frame-Work, diagonal braces 9, between which the arm lies, and pins passing through sai d braces, whereby the arm may be locked in posit-ion to hold the scraper at any desired angle.

In testimony whereof I affix my signature in presence of two witnesses.

h. ELIAS $5 BURHANCE.
