Be it known .that I, HENRY C. INGRAIIAM, of Tecumseh, in -the county1 of Lenawee, and State of Michigan, have invented a new and useful# Machine for Digging Ditches; and I do hereby declare that the following isa full and exactrdescription thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

Figure 1 is a side elevation of iny invention. l

` Figure 2 is a plan of the carriage and section of elevating-,wheel A.

Figure is a perspectiveview of the ploughs and their attachments. y l

Figure -I is a view of a portion of the elevating-wheel A, and of the scoop or chute F, showing its relation thereto. I

Like letters indicateilike parts in all thev figures.

The novelty of my invention consists, first, in the arrangement of al double mould-board plough and'two singlemould-boa-rd ploughs, by means of which the earth is broken up from the line of the ditch andA thrown l.

upon a belt, which passes over a pulleyr lying between the sides of the double mould-board plough and around the elevating-wheel A; second, in the method of elevating the dirt thrown up by the pleugbs or by means of a holt, Q, and an elevating-wheel, A, the dirt being coniin'ed to the perimeter of the wheel, as it revolves, by the` belt Q, and the projecting anges a a of thc wheel; third, in the form and arrangement of a plough-shaped scoop or chute, F, over which the dirt is forced from the top of the wheel, by the actionof the wheel A and belt Q and falls to the side of the line of the ditch; fourth, in the arrangementof the several parts of the mechanism hereinafter set forth and claimed as new. v

To enable those skilled in the art to make and usemy invention, I will proceed .to describe its construction and operation. y Y v l The carriage (which consists of the rectangulariframe- C, longitudinal bars D D', the wheels B B, and their axles) is attached to the tongue E by means of the bolt The object of the carriage is to facilitate transportation and the raising of thc-ploughs and elevating-wheel for the purpose of turning around, passing over anobstruction, die. The axle 4of the eleva'ting-wheelAhas its bearings in a frame, whiclrmay be made of iron, v v, tinted with blue in iig. 2,.the sides of which, o o, are brought toward each other in front of the Wheel A, and are fastened'rigidly to the sides of the tongue E. The wheelAhas two projecting ianges from the rim, (marked a a', lig. 2,) which, with the rim, form a rectangular channel about the wheel. Gr G are sides of a. bifurcated` frame, to which I-I J J are attached. The bars lGr G of the frame are curved upward, and have holes at their upper extremities, through which passes the axle of the wheel A; thus the bifurcated frame, the ploughs, and their attachments, are pivoted on the axle of the wheel A. As the frame C is pivoted to the tongue by the bolt fr, the frame resting upon the wheels B, the excavating mechanism attached to the frame V may be allowed to descend into the ditch, while the wheels B run upon the surface of the ground ou each side of the ditch. The draught and plough-beams bein-g both connected with and turning on the axis of the wheel A directly, they will continue to bear' the same relations to one another at whatever depth the plough maybe cutting in the ditch,

the frame C maintaining a horizontal position, and the pointiof the plough being Set to make a uniform horis zontal cut.- H is a double mould-board plough, having vertical parallel sides, between which'is a pulley, I. In rear of the plough H, attached by standards from the sides G G of the frame, are two single mould-boards, a

right and a left one, so shaped and situated aste throwthe earth turned up by the plough H back in the rear of said plough upon a belt, Q, which passes around the pulley I in the plough H and the elevating-wheel A; also, over' a tightening-pulley, su, which has its bearings in the elastic bar y. From the upper edges of' the sides l Gr' G of the plough-frame are raised two curved segments N, the centre of their curve being in the axis of the wheel A. A part of lthe outer edge of segment M is serrated, and a spring-pawl on the frame V meshes between the teeth, supporting the plough-frame and its attachments. The pawl may be thrown out from the teeth by pressing the lever II toward the tongue. he segment N is bent laterally toward the segment M, and fastened. lhat part of the segment N which is above the beurlsfornls a support for the chute FI The near ange of the wheel A (see fig. 4) is represented as broken away in order to reveal the form ofthe scoop or chute F. The slot in the chute is for the free passage of the near flange, as represented. That part of the chute beyond the slot is between the flanges a a of the wheel A, and the edge thereof lies" close to the rimof the wheel and the further flange. S Ais a eogged segment, which may beattached to or form a. part f segment M R isa. bent lever pivoted at theangle, having a spur or cog, which. meshes into' the cogs'of segment S. From its'lower extremity aA rod descends to one end of a. bent'lever, K, which lies along the side of the ploughfranie G, conforming in shape thereto, having a wheel, L, at the other end, and;y having for its flcrum'a bolt Athrough the' forward end of the plough-frarne. At the back end of the frame V is acurved segment, U, the

centre of its curve being the bolt y. This segment has a serrated edge, into which a pawl on the carriageframe C catc'hes. The drivers seat Z is supported by suitable braces fromlthe iron frame V V.- `The longi-` tudinal bar D-is curved downward, so as not to interfere with the chute F. There may he'small spurs c c c on the flanges a a of the elevating-wheel A, to prevent it slipping. O is a curved lever, the `edgeof which, 'near the end of' the shorter arm, is bcntover toward the segment U, and made so as to lit between the vteeth thereof.

. U Its fulcrurn P is fastened to the bar D of 'the carriage,v

. The operation of this machine is as follows: The pawl that meshes into thev teeth of the segment U being thrown out of mesh, the wheel A will rest upon the ground,l 'The horses are attached lto the tongue E, and the operator takes the seat Z, presses hislfeotA against the lever H, which throws ou-tthe pawl from the teeth of the segment M, which allows 'the ploughs todcscend until they reach the ground, adjusts the wheel L by means of the bent lever K, so that the ploughs will cut a suitable furrow, and then drivesalongV the line of the ditch.

The furrows thrown from the double mould-board plough H are thrown back upon the belt Q, which lies in th'e furrow made by the plough H, and into th'e rectangular channel of the wheel A, where it is confined by the 'belt' A C r Q as the wheel revolves, the tightening-pulley :v keeping theb'elt taut. The earth passes over `the chute'F and falls to the side of the line of the ditch. If the operator wishes to run the plough out of the ground, he will draw the lever R toward him, and by drawing the segment S toward him he will raise the ploughs entirely from the ground, and by working the'levcr O he may raise the elevating-wheel A. Thus thermachine may-be made very portable, being supported by the carriage-wheels B B. As 'the machine takes but a light furrow, it is necessary to pass over the line of the ditch repeatedly until tbe-ditch is sunk tothe required depth. I

-What I claim as new, and -desire to secure by Letters Patent, is`- 1. The combinationo'i the doubleanged wheel A and belt Q, which, revolving in the-same direction, will carry the earth `loosened 'by the ploughover the wheel, substantially as set forth. 2.- Attaching the draught and also the plough-frame to the axis of the wheel A, substantially asA and for the purpose set forth.

3. The combination of the double mould-board plough H and single mould-boardJ J with the belt-Q and double-flanged wheel B, substantially as set forth.

4. Hingng the main frame C to the tongue-irons, substantially in the manner and for the purpose set forth.

5. The arrangement of thedouble-iianged wheel A.andchute F, when the latter is so constructed Vas to u serve also as a scraperr for clearing the earth from theiwheel, substantially as set forth.

6. The arrangement of the segments M and N, frame V, and lever and catch H, substantially .as set forth. 7. Thercombination ofthe lever R, rod T, bent arm K, and wheel L, for the purpose o f adjusting the depth of the cut `of the plough H, substantially as set forth. y

8. The combination of the lever O and pawl attached to the frame C and segment U, for raising the wheel A andthe otherrnechanism, substantially as set forth. f f

. 9. The combination ofthe double-{langed wheel A, endless belt Q, `tightening-pulley x, and pulley I, arranged to operate substantially as set forth. r I v I In testimony whereof I have'signed my name to this specification before two subscribing witnesses.
