lmpnovnn onetime-MACHINE.

VThe Schedule refetl'ed to in these Letters Patent and making pa'rt of the same.

`To all whom tt may concern z p Be it knownfthat I, L.; D.` NOBLE, of Cerro Gordo, :in the county of Iiatt and State of Illinois, have invented Improvements iu" Ditching-Machiues; and I do hereby declare that the following is a full, clear,- and exact `description thereof', reference heinghad to the annexed drawing making a part-of this specification, in which` .t Figure lisaplan View; f y

Figure 2` is a vertical `section on line a: x, iig. l;

Y and Figurc is va vertical section on line y y, of fig. 1.

The same letters` areused in the designation of ident-ical partsili the several figures.

My invention` relatestothat class of devices termed 'ditching or :excavating-machines; and

Myim-provernent consists in the employment of a `single driving-wheel, combined withand arranged, in

c relation to the other parts of the machiue,in the man- .y ner more fully set forth hereinafter.

Tol enable those skilled in theart toniakeaiid use my invention, I will proceed to describe its construc- A represents the truck ofthe machine, consisting f of longitudina'iand transverse beams Viirmly bolted to-S gether. 1 That portion of it to which the plow is raty tached is to `,be adjustably fastened. tothe other part, so that the plow can be raisedor lowered as may be necessary. s

In constructing upon it. c

B represents the drivingwheel, tirmly secured up` ou atransverse horizontalshaft or axle, B', having its hearings in that part` of thcitruck which is in` rear of v `the plo-w, as clearly shown injfigs. l and 2. The tread of this wheel may be constructed with transverse ribs, to increase its tractioni irranging a single lriving-wheel directl in rear of `the plow, possesses `the advantage that such `wheel j can run onla-levelwith thc v'pldw,inthe furrow'vmade therebysothat its ribs can: take hold upon the hard y groundat the bottom of such `furrow, and'tlius .greatly Y i increase'the eicieucy` ofthe machine.

G represents the plow mounted' upon front and t `adjustableportion of the truckl Its share terminates in" an inclinedplane, of snit-4 i ujable width, rising towardthe, rear of the machine, and

i `provided with sidefpieces-NO", .which extend "upward,

and are, at *their` upper ends, respectively, secured to a standard, 'c,-`rising `from the jointed ffrarnelj), amtto Y the frame L, soon hedesjcribed. f-

thetruck, a form similar to the` one shown in the `drawing may be adopted, for any' suchform whiehwill enablcQitl to receive and support i the several'driviug parts which"` are lto be mounted D represents au endless elevating-apron, stretched upon rollers, d, which have their bearings in the sidepieces C.

E vrepresents the jointed frame above mentioned, -the two portions of which are, respectively, secured to the rigid and adjustable portions of the truck, ly-

-ing across-the same directly in rear and under the elevating-apron D. Y

.F represents an endless conveying-apron, which is stretched upon rollers, f, the journals of which have their bearings in the sides of the jointed transverse frame.- The outermost rolle'r is placed iu sliding boxesthe position of which -is controlled vby screws, for the purpose of keeping the apron taut at all times.- G Gr are two ground-wheels, supporting that side of the machine which is opposite the driving-wheel.

lMotion isimparted to the elevating and conveyingaprons by the following trains of mechanism:

Upon the outer en d of the axle B' is secured a pul- Vlley, H, which imparts`motiou, through a belt or chain, 71,130 apulley, I.

l This latter-'is keyed to a shaft, K, which has its bearings in the upper part` of the sides' of a flame, L,

which is secured "upon thc adjustable portion' of the truck, at the side ofthe elevating-apron. j The journal of the`upperxnost roller of this apron, lon that side which is next to the frame L, is elongated, and extends through hothsides of such 'fi-ame. Upon thiselongated portion is secureda pinion, N, which is driven by the spur-wheel M, the latter beingsecured upon the shaft K. y i

It `willhe seen that,- as a consequence of thc above described arrangement of gearing, the elevating-apron will be moved in the direction oftl1earro\v'astl1e machine is drawn vforward, so'that, as earth is delivered upon it by the plow, `it will carry it upward, and disclnrge it upon the conveying-apron. ,n

O is a large bevel-wheel, cast in one piece.- with the driving-wheel B, orseparately, in which case it is firmly securedupou the axle B'.

This'wlieel gears with a small bevel-wheel, P, placed upon a horizontal shaft, Q, arranged in boxes secured -upon the truck, at right angles Ito the axle B,and extending towardthe jointed frame.

Upon the front end of this axle a spurewheel, It, is secured, which gears into and drives a pinion, S.

This pinionimparts motion to a shaft, T, to which it is keyed, and which is connected, by means of a universal joint,4 U, to the elongated journal of the in# Aner and end, roller of the conveying-apron, which is thus moved in the direction ofthe arrow,so"that the earth which has been discharged upon Ait by the elevating-apron, `conveyed by it across the machine',` .and delivered at" thefside of and some distance from the ditch dug by the plow.

Having thus described my invention, bottom of the furrow made by such plow, substanlVhat I claim, and desire to secure by Letters Pattially as set forth. ent, is- In testimony whereof I have signed my nztfne'to this A ditching-machine, combining, in its construcspecification in the presence of two subscribing wittion, a. plow, C, elevating-apron D, conveying-apron nesses.
