SPECIFICATION forming part of Letters Patent No. 279,093, dated June Application filed July 81, 1882. '(No model.)

T0 at whom it may concern:

Be it known that I, ANDREW SYLvEs'rER HUGHES, a citizen of the United States, residing at Jackson township, in the county of Hardin and State of Iowa, have invented an Improved Combined Road-Scraper, Cart, and Dump, ofv which the following is a specifica tion.

My invention relates to machines for removing portions of the surface of the ground for the purpose of leveling or grading such surface.

My invention consists in a wheeled frame supporting a scraper-shovel, the bottom of which is arranged to revolve so as to dump or discharge the contents of the shovel, and in.a system of rods, levers, and one or more springcatches, all for the purpose of operating and controlling the same.

My invention also consists in peculiarly-constructed bearings for the scraper-shovel, whereby it is adapted to rise as its bottom revolves, together with. spring-levers for retaining the trunnions of such shovel in their seats in said bearings.

My invention further consists in certain details of construction hereinafter described.

In order that my invention may be fully understood, I'will proceed to describe it with reference to the accompanying drawings, male ing a part of this specification, in which-- Figure 1 is a perspective view of my improved machine from the front end thereof. Fig. 2 is a perspective view of the same from the rear end thereof. Fig. 3 is a side elevati on of the same, the near wheel being removed, and showing the bottom of the shovel as it appears when commencing to revolve. Fig. 4 is a vertical longitudinal section of the shovel.

A A designate the two longitudinal horizontal frame-pieces, which are connected together by two transverse pieces, B B. The former is placed underneath the pieces A A, in which position it is securely fastened -by bolts or otherwise. The piece B rests on top of the pieces A A at their forward extremities, in which position it is secured similarly to the piece B.

0 represents the tongue of the vehicle, the inner end of which is secured to the upper side of the piece B and extends forward, passing beneath the piece B, towhich it is also socurely attached. As here illustrated, the machine is provided with a center -pole for a double team; but it is evident that two shafts, similarly secured to the frame for a single team, may be substituted. The frame is mounted on two ground-wheels, D D, turning on spindles (1, each of which is cast with a flat plate 011 its inner end, by which it is secured to the rear end of each of the frame-pieces A A.

E E designate two pieces, the lower ends of which rest upon the upper side of the piece B, one at either of its extremities upon the forward end of the frame. These pieces E E extend obliquely upward and rearward, and are supported by two upright pieces, F F, which rest upon the frame-pieces A A at their rear ends.

At the upper extremitiesof the oblique pieces E E is atransverse piece, G, which rests upon the ends of said oblique pieces and carries or supports the drivers seat.

Midway of the length-of the oblique pieces E E is a transverse piece, H, the extremities of which are mortised into the inner sides of the said oblique pieces. This piece H serves as a-rest or foot-board for the driver.

Attached to the rear extremity of each of the pieces A A is a loop-shaped bearing, I I, each of which is stayed by a brace, j extendin forward to the under side of the frame.

a Underneath the frame of the machine 1s the shovel J, formed with three sides and open at its front. A shaft or rod, J, extends transversely of the shovel, passing through its sides at points about mid ay of their length, and extending out beyond such sides, so as to form trunnions j, which rest in the lower ends of the loops'I I. This rod J forms the support for the shovel, and the latter plays upon it when raised or depressed as hereinafter described.

Upon the front sides of the oblique pieces E E and extending transversely of the frame is a shaft,l, the ends of which are inserted into bearing-plates attached to the said oblique pieces, the arrangement being such that the said shaft is permitted to turn. Near the righthand end of this shaft K is a vertical hand-le ver, k, attached to said bar and extending upward about three-fourths of its length to withat its forward end,

in convenient reach of the driver and at his right side. This lever also extends downward about one-fourth of its length from the shaft K, and at its lower extremity is attached one end of a rod or chain, k the opposite end of which isattached to the front part of one side of the shovel J.

Near the opposite end of the shaft K from the lever k is a short downwardlyextending arm, 70, to the lower end of which is attached one end of a rod or chain, h the opposite end of which is attached to the opposite side of the shovel J, and to the front part thereof.

Upon the. cross-piece G is placed a hook, y, or other suitable device to engage with the upper end of the lever 7t, and hold it in its retracted position.

By means of the shaft K, with its system of levers and connecting-rods, provision is made for raising and lowering the front end of the shovel, by the latter of which movements a scraper, j, upon the forward end of the shovel is brought into action.

The shovel J has a bottom, L, which is rigidly secured upon the transverse rod J, extending transversely of the length of said bot tom and at a point midway of its length. This bottom L is formed with beveled forward and rearward edges, which assist in taking hold upon the surface of the ground during the revolution of said bottom, hereinafter described. Upon the upper part of the rear end of the shovel J is a rock-shaft, J having an upwardlyextending arm, j, and downwardly-extending arms j j and j. The arm j, at its lower end, is connected with a catch, I, which is provided with a spring, as shown, which tends to throw the catch inward or forward. The front part of this spring-catch Z is bifurcated, and within the notch or recess between such bifurcations enter the ends of the shovel-bottom.

Connected to the upper end of the arm j is a rod, h, which passes forward and is connect ed at its forward end to the arm of a foot-lever, l1, upon the footboard H. The forward end of the rod h is formed with a loop, as shown, to afford play at that point, so that the action of the spring-catch Z will not be impeded.

At each end of the shaft J is a downwardlyextending arm, j'-, from the lower end of each of which a cord, i passes forward over a pulley, i mounted on a bracket, 1?, formed on the bearing-plate I, and thence said cord extends to the upper end of a lever, '17 pivoted midway of its length to the rear side of the loop I. Each of these levers i is bent forward at right angles at its lower end, and is pro vided with a spring, as shown in the drawings, by means of which the forwardlyn'ojecting lower end of each of said levers is kept within an opening, i, formed in the rear side of each loop I. By this arrangement the trunnions j are kept within their seats at the bottoms of the loops I, the lower bent ends of the springlevers resting upon the upper sides of said trunnions. XV hen the contents of the shovel are to be discharged the lower ends of the spring-levers are withdrawn by throwing the foot-lever h forward, as hereinafter stated.

Between the inner side of the left-hand bearing I and the left side of the shovel J, and rigidly securcd to the shaft J is a ratchetwheel, j, and mounted on the shaft J, so as to play thereon, is a lever, f, carrying a spring-pawl, j, which engages with the teeth of the said ratchet-wheel. The lever 3' extends upward to within convenient reach of the driver and at the left side of his seat. By throwing the lever 7' forward the front end of the bottom L is depressed so as to strike the ground and start its revolution.

The operation of this machine is as follows: Before starting the machine, after the team has been hitched to the shafts or pole O, the driver throws back the lever is, placing its upper end beneath the hook g, by which means the shovel J is raised off of the ground and held in such position. The bottom L is of course in its closed position, and is locked by the catch Z. Vith its parts thus arranged, the machines constitutes a vehicle, and is drawn to theplace where it is to be employed in leveling or gradin Upon arriving at this place the driver thrusts the lever 7c forward, which allows the front end of the shovel to drop upon the ground. As the machine proceeds the scraper at the front end of the shovel. removes all inequalities of surface, and the material constituting such inequalities is car ried backward and deposited upon the bottom L of the shovel. \Vhen the shovel has been filled with earth its forward end is raised by drawing back the lever k, and the machine is drawn to the place where the load is to be deposited. Upon arriving at the place the foot-lever I1 is thrust forward, retracting the catch I, and also the lower ends of the spring levers The lever j is then thrown forward, which, through the medium of its pawl fengaging the ratchet-wheel j, depresses the front end of the bottom L till it strikes the ground. The machine is drawn along, and as it pro ceeds the bottom L makes a complete revolution about its rod J, the shovel meanwhile rising to allow the end of the bottom to pass underneath it, during which movement the trunnions j move vertically in the bearings l. \Vhen the bottom has completed its revolution the catch Z looks it in position, and the levers 6- return into the bearings I above the trunnionsj. In the successive operations of the machine the several movements of its parts above described are repeated.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is-

1.
