THOMAS W. CLARK, OF THERMAL, CALIFORNIA.

LE VELER AND SCRAPER.

To all whom it may concern:

Be it known that I, THOMAS V. CLARK, a citizen of the United States, residing at Thermal, in the county of Riverside and State of California, have invented a new and useful Leveler and Scraper; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention pertains to a new and use ful combination land leveler and scraper; and the invention in its fundamental principles resides in providing a device of this character which may be suitably adjustable so as to provide a land scraper, the parts of which are rigid correlatively with one another; to provide a land leveler, the parts of which may be adjustable with relation to one another, and in such wise as to dispose the said leveler at different angles, as desired by the operator, so as to level land.

The invention directs as a further object to provide a combination land scraper and leveler having specially designed runners, comprising a permanent runner, and an auxiliary runner, each of which is designed for a separate and distinct function, as will be hereinafter clearly evident.

The invention aims as a further object to provide a land leveler and scraper, the angularly disposed board of which has an elongated recess for the reception of a steel plate which is fastened therein by means of suitable screws, or other means may be ,employed, if desired.

The invention has for a further object, to provide means for fastening the permanent runners to the angularly disposed board of the land leveler and scraper, which means comprises a dove-tail tongue and groove connection and suitable screws or other means for holding the runners from transverse displacement.

A further object of the invention is to construct the detachable metallic auxiliary runners in one piece, by means of a casting process, which auxiliary runners comprise a. broad tread portion, an angle portion to connect to the permanent runners by means of screws and bolts, and a web portion between the tread and the angle portion, as will be clearly understood from the drawings.

This invention comprises further objects and combinations of elements, which will be hereinafter more fully described, shown in Specification of Letters Patent.

Serial No. 439,847.

the accompanying drawings, and the novel features thereof will be pointed out by the appended claims.

The features, elements and the arrangement thereof, which constitute the above entitled invention, may be changed and varied, that is to say, in an actual reduction to practice with the understanding that the changes and variations accruing from said reduction to practice are limited to the scope of the appended claims.

To obtain a full and correct understanding of the details of construction, combinations of features, elements and advantages, reference is to be had to the hereinafter set forth description and the accompanying drawings in connection therewith, wherein Figure 1 is a perspective view of the com bination land leveler and scraper, showing the same utilized as a leveler. Fig. 2 is a sectional view on line 2-2 of Fig. 1. Fig. 3 is a sectional view on line 33 of Fig. 1, showing clearly the construction embodied in connecting the permanent and detachable auxiliary runners. Fig. 4 is a perspective view of the combination land leveler and scraper showing the same employed as a, scraper, the parts of which are rigid with relation to each other. Fig. 5 is a sectional view 011 line 55 of Fig. 4:, showing the connection between the permanent runners and the angularly disposed board of the land leveler and scraper.

In regard to the drawings, wherein similar reference characters indicate corresponding parts in the several illustrations, by figures, l designates the angularly disposed. board or member, of the land leveler and. scraper, the lowermost edge of which, as at 2, being longitudinally recessed, for the reception of the plate 3, which may be constructed of any suitable metal, and is secured in said recess by means of bolts 4, as seen clearly in Figs. 1, 2 and 4. At each end of this angularly disposed board or member 1 is secured a permanent runner 5, the connection between which and the said angularly disposed member is of the dove-tail tongue and groove construction, as seen clearly at 6 in Figs. 8 and 5 of the drawings; it will be further seen in Figs. 3 and 5 that the said permanent runners are secured against transverse displacement by means ofthe screws 7 which enter the center of the said dove-tail tongue and groove.

The permanent runners are brought into CTI play, when the device is used as a land scraper, and the parts thereof are held in a rigid relation with each other, as will be observed in Fig. 4 of the drawings.

Upon reference to Figs. 1, 2 and 3 of the drawings, it will be found that the permanent runners have secured thereto detachable metallic auxiliary runners 8, which are provided with a tread portion 9, an angular portion 10, which connects to the permanent runner 5 by means of screws and bolts 11 and 12, and a web portion 13, all of which is cast in one piece at the same time. The broad tread portion of the detachable auxiliary runners is designed for the purpose of preventing the runners from sinking but little into the soil or land to be leveled, the curvature of which tread portion, as seen in Figs. 1 and 2, will readily allow the land leveler or scraper to glide easily over the land, and will also allow the angularly disposed member or board 1 to be adjusted or disposed at difierent angles, as desired, and by means which will be hereinafter set forth.

The angle portion of the auxiliary runners comprises a horizontal portion 14, which engages the tread of the permanent runner, and a vertical bracing or supporting portion 15 which engages the inner surface of the said permanent runner, as will be seen clearly in Fig. 3 of the drawings. The angularly disposed member or board 1 is provided with eye bolts 16, which project or extend from the lower surface thereof, and the shanks 17 of which eye bolts extend through said member 1 and have threaded to their extremities nuts 18, to prevent their displacement; connected to the eye bolts are chains or drag members 19 which have a tendency to level and grade the land or to destroy clods of earth or soil, which may happen to be passed by the said leveler.

To adjust the member or board 1 at different angles, a tail-board 20 is hinged thereto, by means of the hinges 21, which comprise a horse-shoe shaped portion 22 and plates 23, which are secured by screws 24 to the said angularly disposed member 1 and the tailboard 20, as seen clearly in Figs. 1 and 4t of the drawing; also secured to the tail-board 20 is a plate 25 having lugs 26, between which the lower end 27 of the lever 28 is pivoted, which lever is provided with a spring-actuated bolt 29 which is held in position by a keeper 30, and is designed for the purpose of engaging the notches 31 of the quadrant or rack 32, for the purpose of holding the said lever in adjusted position, and through the medium of the pitman rod 33, which is connected, as at 34:, to said lever by one end, and by its other end a connection 35 is formed with the angularly disposed member 1, the said angularly disposed portion is held or disposed at different angles, as will be clearly manifest.

To operate the said spring-actuated bolt, a pitman rod 36 is provided, one end of which is connected with said bolt, as at 37, while its other end is connected at 38 to the hand grip 39, which is pivoted, as at 40, adjacent to the handle of said lever, as will be seen clearly upon reference to Fig. 1 of the drawings. In employing the device as a land scraper, the quadrant or rack 32 and the lever 28 are dispensed with, and the rod 33 is pivoted between the lugs 26, thereby holding the angularly disposed member or board 1 and the tail-board in rigid relation with each other, so as to allow the device to be drawn over the land, for the purpose as set forth.

The tail-board in practice should be longer than shown in the drawings, the same being broken away, as at d1, upon which tail-board a seat (not shown) for an operator is fixed. This seat, in practice, should. be in such a position as to allow the operator to easily manipulate the lever, so as to regulate the depth of the angularly disposed member, and also the angle thereof, that is to say, in leveling land.

From the foregoing, the essential features, elements and the operation of the device, together with the simplicity thereof, will be clearly apparent.
