SPECIFICATION forming part of Letters Patent No. 309,548, dated December 23, 1884-,

ApplioaiionliledMart-h5,1584. (No model.)

To ctZZ whom it may concern:

Be it known that I, HENRY HILD, a citizen of the United States, residing at Britt, in the county of Hancock and State oflowa, have invented an Improvement in Graders, of which the following is a specification.

This invention relates to that class of graders which are used to make roads by moving the earth from the ditch at each side of the road to the center thereof to raise the same above the common level, or to load wagons.

The object of my invention is to plow up the earth, and to carry the same the required distance to one side of the furrow, or load it into a wagon at one and the same operation.

To this end my invention consists in the construction and combination of parts, here iii-after described and claimed, reference being had to the accompanying drawings in whieh- Figure l is a side elevation, Fig. 2 is a plan view, and Fig. 5 is a .rear elevation,of my improved grader.

A represents the plow, secured by a vertical post, a, to a longitudinal beam of the main frame 13 of the machine. The frame B is supported on three wheels, D, E, and F, The

wheel 1) is fixed to run in the furrow by means of a vertically-adjustable bifurcated post, (7, in the lower end of which the wheel is journaled. The upper end of this post is pivoted to a lever, e, which is in turn pivoted to the frame B, and the middle of the post passes through the frame. By means of lever e the post (I and wheel 1) may be pressed upen, so as to raise the frame B and take the plow out of the ground.

0 is an are attached to the frame, and provided with pin-holes, into which a pin may be inserted above or below lever 0, either to hold the wheel up from the ground, so that the plow may be guidedas to the depth of its furrow without the assistance of wheel I); or the wheel may be set just as low as the plow to assist the latter in supporting frame B; or the wheel may be thrust low down to support the frame and carry the plow above ground. The wheel D is mounted in a swinging yoke, ltwhich is pivoted at its rear end to the frame B, and at its forward end to a lever, b, which is fulcrumed at c on a stud erected on frame B. This wheel D is to run on top of the ground ahead of the plow, and by raising or lowering it the depth of the furrow may be gaged. The lover I) is held at any desired elevation by a brace, 0, having pin-holes in it, and a pin adapted to pass through said holes and through the lever b.

E is a caster-wheel supporting the forward part of the frame.

F is a large drive-wheel, made rough on its circumference to engage the ground to insure the wheels turning when the machine is hauled along. This wheel F is journaled in a yoke, f, which is pivoted to the frame B atf, concentric with a shaft, G. The drive-wheel F is provided with a circle of gear-teeth, g. which engage a pinion, G, on shaft G.

H is a beveled gear-wheel secured 011 shaft G, engaging another beveled wheel, 7.2, 011 shaft h.

I is an endless apron ol'slats secured together by hingejoints, as hereinafter described, to travel as a belt around the cylinders 2' t". The cylinder 2" is carried very close to the ground, and close to the mold-board of the plow, to receive the earth turned up thereby upon the apron. Thelower end of the frame I, supporting the cylinders i 1 which carry the apron,

i is supported by hangers i,'depending from the frame 13. The middle portion of the frame I rests upon the main frame B, and it may be vertieall y adjustable to set the roller t" high or low.

hen the grader is used for grading only, the frame I will lie at a very slight inclination to a horizontal plane, and will be made to extend beyond the main body of the grader as far to one side as may be desired.

When the grader is used for loading wagons, the frame 1 will be sufficiently elevated at its outer end to carry cylinder i over the wagon alongside, thus enabling the apron I to continually dump its load into the wagon. The frame I is thus a lateral extension of the main frame 13. The apron is rotated by means of achain, J, running from a rag-wheel on cylinder t to a rag-wheel, K, 011 the shaft h of a beveled gear, it, which on gages another beveled gear, H, on shaft G, carried by pinion G, thus engaging with the drive-wheel F. \iVhen the machine advances, the plow turns a furrow of earth onto the apron, which dumps it to one side, or into a wagon hauled alongside, as desired.

Zis a cross-beam secured to the end of the team-pole M, for the double purpose of securing the forward team in proper line of draft at m, and to haul the plow by means of the connecting rod or chain N. The first team of three horses is secured to a draft-rod, n, by means of peculiar equalizing-whiiiietrecs.

Ois the double-tree made in duplicate parts, one above the other, admitting the equalingbars 0 between its parts. The equaling-bars 0 are pivoted one-third their length from their outer ends to the double-tree. On the outer end of each bar 0 is hunga single-tree or whiffletree, P, for one horse each. On the inner ends of both bars 0 is hung another whiffletree, 1?, for one horse to pull against thetwo outside horses. By this means the strain is more direct than by the old style of threehorse gear. A forward team may be secured by the same style of gear to the frame at m. The frame B is raised or lowered relative to the axle of wheel F by means of a rope or chain, R, wound upon an axle, 0', by cranks S, the rope passing around a pulley, T, on

the frame B, and under another pulley, t, on

an arm of said frame, thence upward to the yoke f, to which it is secured. By turning cranks S one way therope R will be wound onto shaft 1, and will draw the frame B at pulley t up toward yokef, and vice versa, the frame B swinging upon the other wheels, D D E, and upon the pivotf of yokef. Either of the cranks S may be pushed through the cranklever into the frame B, to retain the crank at any desired point, and thus hold the frame elevated.

V is a seat for a driver. This seat is supported over the apron on rods extending to the frame B. It is thought that earth may by means of this device be very much more rapidly moved away from the plow which loosens it than by any method of scraping said loosened earth along the ground, inasmuch as A the friction of my carrier apron, revolving upon small journaled cylinders, is less than the friction of any scraper carrying the same load over rough ground; also, this means of 'may have got between the belt may be free to drop out.

\Vhat I claim as my invention, and wish to secure by Letters Patent, is-

1. The combination, with the earth-moving device, comprising the plow A, the beltI, and the driving mechanism described supported upon frame B, ofthe team-connecting rod 12, and the beam or poleM, secured to said frame B, the cross-beam Z, secured to pole M, the team-hitch m,attached to beam Z, and the stayrod N, connecting the end of said beam with the frame B, substantially as shown and described.

2. The combination, with a graderframe provided with a plow and means for carrying laterally therefrom the earth turned up thereby, of a drive-wheel hung in a vertically-adjustable yoke to said frame, a rope or chain attached to said yoke and passing around pulleys on the frame, and means for winding said rope and securing it, whereby the frame may be elevated relative to the yoke and held at the height desired, as specified.

HENRY HILD.
