GRADING AND DITCHING MAC'HINE.

SPECIFICATION forming part of Letters Patent No. 518,905, dated April 24, 1894.

Application filed October 31, 1893. Serial No. 489,654. (No model.)

.To all whom it may concern:

Be it known that I, WILLIAM H. TIDLAND, a citizen of the United States, residing at Nicollet, in the county of Nicollet and State of Minnesota, have invented a new and useful Grading and Ditching Machine, of which the following is a specification.

My invention relates to improvements in road-making or grading-machines; and has special reference to certain new and useful improvements upon that construction of similar machine illustrated in United States Patent No. 291,427, granted me January 1, 1884..

The objects of my present invention are to provide for a new and improved mode for handling and adjusting the plow; to provide means for raising and lowering the excavating or ditching-wheel; to improve the cups and the mode of securing the same upon the ditching-wheel and operating said cups; to provide for an adjustment of the dumpingwheel, whereby the cups are caused to operate for the purpose of dumping at a desired distance from the plow; and to provide for a raising and lowering of the ditching-wheel whereby the same is thrown into and out of operative position.

With these and certain other minor objects in View the invention consists in certain features of construction hereinafter specified and particularly pointed out in the claims.

Referring to the drawings:Figure 1 is a perspective View of a machine embodying my improvements. Fig. 2 is a top plan view. Fig. 3 is a transverse vertical sectional view. Fig. 4 is a detail in perspective of a portion of the rim of the ditching-wheel together with 7 some of the cups.

Like numerals of reference indicate like parts in all the figures of the drawings.

In the practice of my invention I employ a substantially semicircular frame 1, which at one side or at its ends is connected by the longitudinal frame-bars 2, which in turn are suitably braced at points desired. In front and rear bearings between the beams 2 I swivel front and rear caster-wheels3. In the beams 2 I also locate a pair of transversely disposed cranked-shaped rock-shafts 4, c0nnecting said shafts by means of a pair of plow-beams 5. To the lower ends of these plow-beams I secure an ordinary side-plow 6, whose moldboard is toward the interior of the framework. It will be obvious that through the medium of the lever 7 which is pivoted at the inner side of the inner beam 2, the said'plow-beams may be raised and lowered, and by reason'of the fact that they are connected to two similarly cranked rockshafts, the bottom of the plow, that is the point and heel, will also be on the same level whether the plow be elevated out of operative positionor lowered into operative position. Any means may be employed for giving motion to the plow, and in the present instance, as seen, I pivot the lever 7 to alocking standardz8 providing said lever with a lockingpawl 9 for engaging the standard.

At the front of the beams 2 I locate a seatstandard 10, which supports a seat 11 for the accommodation of the driver, it beingunderstoodthat the draft-mechanism is applied at the front end of the machine, as shown. In rear of the plow, or rather immediately above the same, I locate a second standard 12 which supports a seat'13 for the accommodation of the operator who is positioned at this point for the purpose of manipulating the levers and other devices of adjustment heretofore and hereinafter described.-

The opposite side of'the semicircular frame 1 is provided with a. cross-bar l4, and the same, together with the frame 1, accommodates a transverse axle 15, upon which is mounted for rotation a ground-wheel 16. A standard 17 rises from the front side of the frame 1 and terminates in an eye, and at the rear side of the frame 1 a pair of standards 18 rise and accommodate a winding-shaft 19, at whose inner end or adjacent to the seat 13, there is located a lever 20 or other windingdevice by Which means the shaft 19 may be oscillated. A chain 21 is wound upon the shaft 19, and at its free end is secured at the rear end of the frame 22. An oblong frame 22 is located in the semicircular frame'l, and at its front end is provided with an eye 23 which engages with the eye at the upper end of the standard 17. The rear end of the frame 22 is also provided with an eye, and in the same is'coupled the lower end of the chain 21.

By means of the eye 23 being coupled with the standard 17, it will be seen that the rear end of the frame 22 is capable of raising and lowering, which raising and lowering I accomplish through the medium of the lever 20 operating the shaft 19 to wind the chain thereon or pay the same therefrom. The frame 22 is held a proper distance from the plow by the bar 22, pivoted to the frames 22 and 1, as at 22. Opposite bearings are arranged in the upper and lower sides of the frame 22, and in the same is mounted for loose rotation an inclined shaft 24. This shaft 24: serves as the axis of the ditchingwheel 25,which as shown, is a large wheel located in the frame 1 and extending from the outer edge thereof to a point adjacent to the moldboard side of the plow. The rim 26 of the wheel 25 is provided at intervals with bearing-eyes 27, and passing through the same is a rod 28. This rod 28 forms a bearing for a series of longitudinally curved, hinged or pivoted dirt conveying cups 29, which radiate toward the center of the wheel and normally lie upon the same. Each of these cups is provided at its inner end with an eye 30, and passing through the eyes of the series is a loose slat connecting chain or belt 31,whereby the entire series of cups is connected. The bottom of the wheel, it will be seen, travels upon the ground-wheel 16 at one side and being inclined, as shown, at its opposite side or that side adjacent to the plow, travels upon the ground, so that as the machine is drawn along the wheel 25 is revolved by reason of its contact with the ground and the said wheel 16.

Acurved track 32 extends from the rear end of the frame 22 concentric with the shaft 2a thereof to a point near the front end of the frame 22, and then abruptly bends outward and downward forming a standard 33, whose lower end is fastened to the semicircular frame 1. Aswinging-arm 34: is pivoted at its inner end to the upper end of the shaft 24:, and at its outer end is bifurcated, as at 35, and accommodates a vertical pin or journal 36 upon which the dumping-wheel or disk 37 is mounted. A yoke 38 of U-shape has its terminals connected with the track 32, passes under the dumping-wheel 37, and forms a lower additional bearing for the journal-pin 36. This yoke is designed to travel upon the track 32 and aid in supporting the arm 34 upon the track. The arm is also provided with an eye 39 upon its upper side, which loosely engages with the track 32. By this means the dumping-W11 eel is located and supported above the periphery of the wheel 25 and slightly inside the same, and inasmuch as the series of connected cups pass over the wheel 37, it will be seen that each is successively brought to a vertical position, to dump its contents upon the ground at such a point as maybe regulated by the position of the wheel 37 In order to provide for a convenient adjustment of the wheel 37 I connect with the journal-pin thereof a curved rod 40, which terminates at one end in a handle 41, and

passes through a guide-eye 42 formed in a guide-standard 43 which rises from the frame 22, the handle being in easy reach of the operator when mounted upon the seat 13. A pair of hangers 4C4: depend from the upper frame-bar of the frame 22 at the upper end of the same, and in the lower ends thereof is journaled a depressing-wheel 45 which travels over the series of cups, depressing them upon the wheel 25 as they leave the dumpingwheel 37 whereby they are forced back positively to their refilling positions. This completes the improvements upon my formerconstruction, and it will be seen that I provide, as before stated as being the objects of my invention, first, a convenientmeans for raising and lowering the plow; second, a convenient means for raising and lowering the ditching-wheel; third, a convenient means of attaching the cups to the ditching-wheel; fourth, means for' adjusting the dumpingwheel, whereby the latter is caused to dump the dirt at a desired distance from the plow which is forming the ditch; and, finally, I provide for a depression of the cups afterthe same have dumped and are about to be refilled.

The operation of the machine, it Will be understood, is similar to that described in the previous patent heretofore referred to and may be briefly stated as fo1lows:-The ma chine is drawn along with the plow at the side of the road,said plow forminga ditch, as will be obvious, and the soil turned up by the moldboard of the plow is deposited upon the cups as they are successively brought adjacent to the plow. These cups are carried by the wheel 25 and are successively operated upon by the dumpingwheel, or in other words, are elevated and their contents discharged from the machine at any point of the road, the point being varied in accordance with the width of the road and the desired convexity of the road-bed in a manner obvious. I

I do not limit my invention to the precise details of construction herein shown and described, but hold that I may vary the same to any degree and extent within the knowledge of the skilled mechanic.
