REVERSIBLE ROAD AND DlTCHlNC IVIACHlNE.

SPECIFICATION forming part of Letters Patent No. 377,041, dated January 31, 1888.

Application filed July 6, 1886. Serial No. 207,251. (No model.)

To aZZ whom it may concern.-

Be it known that I, HENRY CLARKE MOORE, a citizen of the United States, residing at Tania City, in the county of Tama and State of Iowa, have invented certain new and useful Improvements in Road or Ditching Machines, of which the following is a description.

My invention relates to improvements in the class of road or ditching machines which are mounted upon four-wheeled vehicles having a direct front draft; and it consists in the construction and combination of parts hereinafter described and claimed.

The object of my improvements is to so construct and arrange the parts of the machine as to combine the advantage of a direct draft with the reversibility and angular adjustment of the position of the scraper or plow, whereby the machine is adapted to a wider range of I attain this object by the mechanism illustrated in the accompanying drawings, in which the same letters of reference indicate the same parts, and in which Figure 1 represents a plan view of my machine, showing the scraper, the devices for regulating the position of the same, and the draft-beams in full and dotted lines. Fig. 2 represents a side elevation of the machine, and Fig. 3 shows a detail end view of the scraper and one of the swivel-connections.

In the drawings, A represents the frame of the machine, which is of any ordinary or suit able construction and mounted upon the bolsters of the vehicle. Arranged beneath this frame, between the front and rear wheels, is the steel scraper B, which is of alength some what greater than the general width of the machine, and is provided longitudinally with a straight face and transversely with a curved face, as shown in-Figs. 2 and 3 of the drawings. Upon the rear side of this scraper, below its center and near its ends, are open brackets b l), and at its upper edge and near its ends are secured supports 1) b, in which are swivelingly secured the bent or curved draftbeams b I). At their forward ends these draft-beams are provided with apertures, through which pass the grab-hook b and chain c, for connecting them to the draft-iron c, to which the team is attached.

The letters (1 and erepresent two guy-chains,

attached, respectively, to the rear or discharge end of the scraper and to grab-hooks If b and I) b attached to the frame A, the chain d extending rearwardly and upwardly from the scraper to one of the books If, and the chain 6 extending forwardly over said scraper to one of the hooks b These chains are all detachably secured and adj ustable as to length, and the grab-hooks are arranged on both sides of the frame, so that together they hold the scraper securely when reversed, or in whatever position it may be adjusted.

Suitably secured to the front and rear ends of the scraper and projecting upwardly there from are vertically-adjustable rods or bars g g, which are pivotally and adj ustably secured at their upper ends to the outer ends of the operating-levers g g, the latter being fulcrumed in the upper ends of the standardsg g. These standards are secured to the ends of the re Versible or traverse bar C and braced fromthc ends thereof by the forked supports 0 0 This traversebar is arranged beneath the frame and above and parallel with the scraper, and is also of a length somewhat greater than the width of the machine, and is longitudinally movable across the same. It is mounted upon rollers c" c", journaled in the lower ends of the traversing or movable frames or carriages 0 which are arranged on both sides of the ma chine and provided at their upper ends with grooved disks 0 0. These disks rest between and are adapted to run upon the iron tracks or bars 0 0 which are bolted to the sides of the frame.

Attached to the traverse-bar G at its center is a hand or operating lever, C; also, the rear end of a rod or bar, 0, is pivotally attached to the center of said traverse-bar at the point x, the front end of said rod or bar being pivotally secured to a cross-bar, C of the main frame. Near the rear end of bar 0 is formed a series of holes, 00', in one or the other of which a pin, x, is to be placed. In changing the angle of the traverse-bar by the movement of the hand or operating lever C, said bar impinges upon the pin 00, and its ends are moved to the desired position outside of the frame to the rear or front. By turning the hand-lever O to the right or left the trav erse-bar, the traversing frames or carriages, the standards, the levers, and the rods will be moved to the right or left, and with them the scraper, first having disconnected the chains 0, (Z, and e and the draft-beam 71 which is attached to the draft-iron. By transferring the draft-chain to the opposite draft-beam and to the opposite shank of the draft-iron, and again attaching the chains under the proper or desired adjustment as to length, the scraper or plow may be arranged-at any desired angle; or, when desired, it may be moved to and se cured in the reversed position shown by the dotted lines in Fig. 1 of the drawings,the other parts also assuming the corresponding positions shown in dotted lines.

It will be obvious that in throwing the traverse-bar O by the hand-lever 0 toward either side of the frame the degree of the angle of said traverse-bar with respect to the frame is only controlled, as far as the range of its movement will permit, by the vertical rods or bars gg and the sides of the frame A; also, that when the scraper or plow is raised by the rods 9 g and levers g y it will be sustained by the traverse-bar O, and that when the chains 0, d, and e and the draft-beams b b are disconnected it falls by its own weight into line with said traverse-bar B; also, that the change of the angle of the scraper or plow relative to the draft-beams b" b and levers g g and rods 9 g is permitted by the swivel-connections b b and b b of said draft beams and rods with the scraper. It will also be noticed that by means of the guy-ehains d and e, attached to the delivery end of the scraper, and the freedom of play of its various connections, an increased acuteness of the angle of said scraper can be effected by the adjustment of the chains in their respective grab-hooks; also, that the scraper, when at work, is held firmly in any desired position or adjustment by the connections between the same and the draft-iron c 1 and the frame A.

The dotted lines in Fig. 1 show the reversed position of the scraper or plow and its draftconnections with the adjustable draft-chain c shortened, whereby the scraper. is brought farther forward or more at right angles with respect to the frame than it is as shown in full lines; also, the positions of the draftbeams, as arranged at the delivery end of the scraper or plow, are shown in dotted lines in said figure, and also the adjustable draftchain c, as passed through the loop b"',attached to the lowerend of the guy-brace b on the right side of the machine.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. The combination,in a road or ditching machine mounted upon wheels, of a reversible scraper or plow,a traverse-bar,movable frames provided with grooved disks journaled therein, and the tracks or bars, substantially as described.
