ROAD GRADING AND DITCHING NIACHlNE..

ST'ECFIGATION forming part of Letters Patent No. 775,990, dated November 29, 1904, Application filed June 4. 1903. Serial No. 160,006. (No model.)

T0 all whom it may concern:

Be it known that I, RICHARD RUSSELL, of Stephen, county of Marshall, State of Minne- "sota, have invented certain new and useful Improvements in Road Grading and Ditching Machines, of which the following is a specilication.

My invention relates to that class of grading and ditching machines sho wn and described in Letters Patent of the United States issued to me May 12, 1903, No. 7 27,693.

The object of my invention is to simplify and improve the mechanism of the machine shown in the above-described patent.

A further object is to provide means for rigidly securing the ditching-plow and holding the same in place while the machine is in use.

`A further object is to provide an improved construction of the frame whereon the plow is supported.

Other objects of the invention will appear from the following' detailed description.

Theinvention consists generally in various constructions and combinations, all as hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure 1 is a plan View of a grading and ditching machine embodying my invention. Fig. 2 is a side elevation of the machine on the side where the plow is located. Fig. 3 is a similar view of the opposite side of the machine. Fig. 4L is a transverse vertical section substantially on the line a' .fr of Fig. 1. Fig. 5 is a perspective of the front of the plow and the frame whereto it is secured'and whereon the traveling apron is also supported.

In the drawings, 2 and 3 represent, respectively, the forward and rear axles, having wheels 4 and 5 and supporting a horizontal platform 6. A rectangular frame is arranged transversely beneath the said platform, consisting' of parallel angle-.bars 7, connected at one endy by a cross-bar 8 and rigidly secured against spreading or twisting at their other endsk by the diagonally-arranged braces 9. The frame is arranged at an incline under the platform and is supported at its discharge side by pivoted links 10, that are connected to the bars 7, respectively, and to the ends of an oscillating bar 11, that is pivoted at a point intermediate to its ends upon an upright standard 12, provided with a series of holes 13. These holes render the bar 11 vertically adjustable on the said standards and permit the operator to elevate or depress the said frame at the discharge side of the machine. Braces 14 are preferably provided on the platform 6 and secured to the standards 12. Near the opposite end of the frame on the receiving side of the machine l provide a horizontal plow-beam 15, secured to the ends of braces 16, that are bolted to the bars 7 at a point near the middle thereof and are held at an ineline by bracing-straps 17, that connect thc braces 16 with the lower ends of the bars 7. A post 1S is secured to the under side of the beam 15 and at its lower end is bolted to a landside 19, in front of which is the mold board 2() and the plowsharc 21. rlvhe rear end of the plowshare Q1 is rigidly secured to the adjacent rail 7 by a bar 22, and a strap 23 connects the moldboard with the bar 2Q and serves to hohl the board firmly in place. lhe plowshare 21 has an upwardly-tnrned `flange portion 241, the edge Q5 of which is turned over the cross-bar 8 andv bolted thereto. The iiange 24 serves two purposes. It guides the earth excavated by the plowshare up to the' moldboard and to the traveling apron and allows the plow-point to enter the desired distance into the ground, but preventing the end of the apron-supporting frame from touching the ground. From the foregoing it will be noted that the working parts of the plow are rigidly secured and that there will be no possibility of their becoming twisted ont of their proper position with respect to the .frame and .the traveling apron while the machine is in operation. Any suitable mechanism may be employed for raising and lowering the plow and .therccciving side of said frame; but l prefer to provide bars 26, pivotally connected with the braces 16 and having a series of perforatiol'is Q7, that are adapted to receive pins, provided on the arms-29, that are carried by the pivoted levers 30. These levers are secured to one side of the frame 6 and are movable over toothed quadrants 3i, that are engaged by locking devices 32, carried by said levers. By operating these levers the bars 26 can be raised or lowered to elevate the forward and rear edges of the apron-supporting frame simultaneously or to tilt one edge or side independently of the other, according to the character of the ground where the machine is used. If the operator desires to have the plow dig deeper into the soil, he will operate the rear lever and tilt the frame forward. A corresponding movement of the forward lever will cause a reverse movement of the frame. A depending post 34 is provided on the platform 6 in front of the apron-frame and acts as a guide therefor, and it also prevents the discharge end of said frame from swinging forward when the plow is forming' the ditch. A brace-rod 35 connects the post 34 with a bolster 36, supported on the forward axle. A timber 35 is bolted at one end to the plowbeam l5 and at its other end is provided with an ang'le-plate 35, that is secured to the said timber and is slidably mounted on the bracerod 35. A rod 36 connects one of the bars 26 with the frame 6 and is provided with a threaded end and a bur 36, by means of which the operator can move the suspended frame laterallyT with respect to said wheeled frame and take up the slack in the aprondriving chain or loosen the same. The timber 35 serves to brace and strengthen the operating parts of the machine and aid in holding the plow rigidly while at work. A draft-link 37 connects the timber 35 with the forward axle. Mounted in bearings at the receiving' end and near the middle of the apronframe are idle rollers 37, and at the discharge end of said frame is a shaft 38, carrying a cylinder 39 of greater diameter than the rollers 37 and over which and said idle rollers an apron 40 travels. Any suitable means may be provided for moving said apron; but I prefer to provide a sprocket-wheel 4l on the shaft 38, connected by a chain 42 with a sprocket 43, that is mounted on a shaft 44, supported in bearings in hangers 45, suspended beneath the platform 6. A sprocket 46 on the shaft V44 is connected by a chain 47 with a similar sprocket 48 on a crank-shaft 49, that is operated by a gasolene-engine 50, mounted on the platform 6, preferably near the middle thereof.

The operation of the machine is as follows: The operator having adjusted the plow the desired height from the ground will start the engine and set the apron in motion, and the plow as the machine is moved forward will dig into the soil, and the gravel lifted up by the plowshare will be directed by the flange 24 and the moldboard 2O up onto the traveling apron, which will convey the material to the middle of the roadway. The flange 24,

having a sharp forward edge, will act as a fincolter and besides guiding the excavated material up to the moldboard will prevent the receiving end of the apron-frame from coming in contact with the ground.

The apparatus herein described is extremely simple in construction and at the same time is strong and durable. The traveling' apron can be set at any desired angle, according to the slope of the roadway and the depth of the ditch, and the plow rigidly secured to the apronframe cannot be twisted out of position and will cut a ditch of uniform depth and will be operable with a comparatively light draft.

I claim as my inventionl.
