GRADING AND DITCHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 620,725, dated March 7, 1899.

Application filed March 30, 1 8 9 8.

To @ZZ wiz/0m t 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.

This invention is in its nature an improvement on the grading and ditching machine forwhich Letters Patent of the United States were granted me April 24, 1894, No. 518,905, and relates to novel and better means for connecting the inner ends of the cups of the elevator-wheel, means for mounting the dumping-wheel so as to admit of its adjustment, the hangings for the plow and the frame carrying the elevator-wheel, au attachment for loading the earth into a Wagon for conveying it to a point distant from the part of the road being graded, and, lastly, to the improvement of the general construction, whereby the draft is lightened, the parts caused to Work to better advantage, and the machine made more durable and effective.

For a full understanding of the merits and advantages of the invention referencevis to be had to the accompanying drawings and the following description.

The improvement is susceptible of various changes in the form, proportion, and the mifrom the principle or sacricing any of the advantages thereof, and to a full disclosure of the invention an adaptation thereof is shown in the accompanying drawings, in which- Figure 1 is a perspective View of the machine as seen from the front, the loading attachment being in position. Fig. 2 is a perspective view of the machine viewed from the rear, the loading attachment being omitted. Fig. 3 is a top plan view, the outer end portion of the carrier being omitted. Fig. 4. is a transverse section of the machine as seen in Fig. 3, looking toward the front. Fig. 5 is a detail view showing the means for raising and lowering the plow. Fig. 6 is a detail view of the shaft to which the front ends of the plowbeams are connected, the dotted lines showing the clips. Fig. 7 is a detail view of the outer end portion of a cup.

Corresponding and like parts are referred Serial No. 675,769. (No model.)

to in the following description and indicated in the several views of the drawings by the same reference characters.

The framework for supporting the workin g parts comprises longitudinal beams l, disposed in parallel relation, and a laterally-extending frame-bar 2, deflected outwardly between its ends and having'its end portions rigidly connected to the extremities of the longitudinal beams 1. The end portions of the deflected frame-bar 2 are bent upwardly and secured to the lower side of the beams 1, and its outer deflected portion is in a lower plane than the said beams 1 and is supported by a ground-wheel 3, which also serves as a driver for the carrier-apron of the loading attachment. Front and rear caster-wheels 4 are applied to the longitudinal beams 1 and support the side of the frame opposite the ground-wheel 3. A seat 5 is provided at the frontend of the frame for the accommodation of the driver, and a second seat 6 is located near the rear end of the machine for 'the convenience of the operator manipulating the several parts required to be adjusted. The pole or tongue 7 has connection with the front portion of the deflected frame-bar 2, and the team for drawing the machine is hitched thereto in any of the usual ways.

An oblong frame 8 extends longitudinally of the frame and has adjustable connection at its front end with the main frame by means of an angle-plate 9, securely bolted to the front end of the frame 8 and having its forwardly-extending flange provided with a ver tical series of openings 10 and a lug 11, bolted or otherwise applied to the front portion of the bar 2, and having an opening to register with any one of the openings 10, and through which registering openings a bolt or pin passes to secure the front end of the frame 8 in an adjusted position. A lever l2 is pivotally connected at one end with abifurcated hanger 13 near the outer rear corner of the main frame and is firmly secured at its opposite end to the frame 8, which is connected by a chain or cable 14 with aA transverse shaft 15, journaled at its ends in bearings applied to the main frame, whereby the rear end of the frame 8 may be adjusted vertically by vturning the shaft 15 in its bearings. A wormwheel 16 is secured to one end of the shaft15 IOO and meshes with a worm-thread 17, provided are arranged to come upon opposite sides of at the rear end of'a shaft 18, journaled to the main frame, and having a crank 19 at its front end Within convenient reach of the operators seat 6.

A shaft 20, constituting an axle or spindle for the elevating-wheeh'is supported at its ends b y means of the upper and lower bars of the oblong frame8. The elevating-wheel 2l comprises a rim, spokes, and a hub and is mounted to rotate upon the axle 20. The cups 22 are hinged at their outer ends to the rim of the elevating-wheel and are adapted to move vertically at their inner ends, so as to dump the load at the proper point. Strapirons 23, doubled upon themselves so as to form eyes 24, are bolted or otherwise secured to the inner ends ofthe cups 22 and receive the chain 25, by means of which the inner ends of the cups are connected and held at fixed distances apart when the machine is in active operation. This chain 25 passes through the eyes 24, and pins or bolts 26 pass through the eyes 24 and links of the chain 25 and positively connect these parts, so as to insure the inner ends of the cups maintaining a fixed relation when elevated by means of the dumping-wheel. The strap-irons 23 serve to stiffen and strengthen the inner ends of the cups and when worn can be easily and cheaply replaced.

An arm 27, comprising upper and lower bars and an intermediate brace, is pivotally mounted upon the axle 20 at its inner end, and its outer end is free to swing and supports the dumping-wheel 28, which is located so as to engage with the cups and elevate their inner or free ends, thereby effecting the dumping of the soil. A cross-bar 29 is secured to the arm 27, about midway thereof, and is strengthened at its extremities by means of a truss-brace 30, made fast at a middle point to the lower bar of the arm 27. Eyebolts 3l are located at the ends Vof the cross-bar 29 and are slidably mounted upon a curved rod or bar 32, which is secured at its ends to the upper portion of the oblong frame 8. The curved rod or bar 32 serves as a guide and brace for the swinging arm 27 forward. This forward tendency of the dumping-wheel is overcome by means of a chain or like connection 33, secured at its front end to the outer end of the arm 27, and steadies it when in an adjustedposition. The strain upon the dumping-wheel is from the rear, thereby tending to move the dumping-wheel and the outer end of the arm 27 and having adjustable connection at its rear end with a notched lug 34, secured to the rear portion of the upper bar of the oblong frame 8. By adjusting the chain 33 so as to vary the distance between the lug 34 and the outer end of the swinging arm 27 the position of the dumping-wheel can be varied, thereby providing for dumping the load at any desired point.

The plow 35 has a pair of beams 36, which the outer'longitudinal beam 1, wherebyA it is possible to operate the machine close to a felice or ditch. A transverse shaft 37 is journaled at its ends to clips 38, which have adjustable connection with the front ends of the beams 1, so that the plow may be given any desired pitch. The inner end of the shaft 37 is provided with an arm 39, and its outer end has applied thereto a bell-crank lever 40. The front ends of the plow-beams 36 have pivotal connection with the arm 39 and the rear arm of the bell-crank lever 40. Upon turning the shaft 37 in its bearings the front ends of the plow-beams can be raised and lowered. A toothed segment 41 is pivoted to one of the longitudinal beams 1 andhas oppositely-extending arms 42. A shaft 43, having a crank at its rearend accessible from the attendants seat G, is journaled in a bracket 44, secured to a beam l, and this shaft has a worm-thread 45 in mesh with the toothed portion of the segment 41, whereby the latter can be turned so as to move the arms 42 for effecting a raising and lowering of the plow' as required. The front arm is connected with the front arm of the bell-crank lever 40 by means of a rod 46, and the rear arm is connected by means of a vertical rod 47 with the plow 35. The train of connections between the plow and plow-beam are so proportioned and disposed that the plow and beams move so as to maintain a parallel relation, which is essential, so as not to disturb the pitch of the plow when once adjusted. The moldboard of the plow is arranged with reference to the elevating-wheel 21 so as to throw the earth thereon.

Standards 48 rise vertically from the outer portion of the deflected frame-bar 2 and are braced at their upper ends by guys 49, connecting with a longitudinal beam 1. A frame 50 has pivotal connection at its inner end with the lower ends 0f the standards 48 and supports a carrier belt or apron 5l, of rubber, canvas, leather, or other suitable material. The upper portion of this carrier ybelt or apron is supported by rollers 52, applied to the side bars of the frame 50 and located intermediate of the extreme rollers, around which the carrier-belt passes. Chains or cables 53 connect at their outer ends with the outer extremity of the frame 50 and pass over direction-pulleys at the upper ends of the standards 48 andare secured at their inner ends to a windlass or shaft 54, journaled in bracketbearings applied to the main frame. By operating the windlass or shaft 54 the outer end of the carrier can be raised or lowered, so as to discharge the earth into a wagon of greater or less height or whereby the earth may be dumped at any desired point situated at a distance from the road or surface being graded or level.

A shaft 55 is journaled longitudinally of the frame and in proximate relation to the ground -wheel 3 and is provided with a roo IOS

IIO

sprocket-wheel 56, around which passes a drive-chain 57 for transmitting motion from the said shaft to the outer roller supporting the carrier belt or apron. A series of idlepulleys 5S receive between them the parts of the drive-chain, thereby preserving a uniformity of tension upon the drive-chain at the various adj usted positions ofthe conveyer. The middle pulley 5S is about in line with the pivotal connection of the frame 50 with the standards 48. Hence when moving the outer end of the frame 50 up or down the tension upon the drive-chain is not materially at'- fected. Side pieces 59 are secured to the frame 50 and prevent the earth from falling laterally from the upper portion of the carrier-belt. The shaft 55 receives its motion from the ground-wheel 3 and is provided at its inner end with a bevel-gear 60, which intermeshes with a corresponding bevel-gear Gl, mounted upon the hub of the groundwheelv 3. A clutch 62 is provided to secure engagement between the bevel-gear Gl and the hub of the ground-wheel 3, thereby admitting of the carrier being thrown into and out of gear. The tread of the ground-wheel 3 is inclined and corresponds with kthe inclination of the frame of the elevating-wheel.

Then the machine is in operation and drawn over the road or surface to be graded or leveled, the earth loosened by the plow is thrown upon the lower portion of the elevating-wheel and is carried by the latter to the opposite side of the machine and is dumped by the rising of the cups. Vhen it is required to load the earth into a wagon or convey it to a point remote from the surface being acted upon, the carrier is placed in position and thrown into gear and the earth from the elevating-wheel is delivered to the inner end of. the carrier and is moved by it outward and away from the machine and dumped at thev side of the road or into a wagon, as required.

It is to be understood that the several intermeshing gears are to be housed to protect them from the dust and dirt, said housings being omitted in order not to conceal and hide the operating parts.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-
