ing in a circle, and drawing" a lever, or
sweep. This sweep is attached to a vertical shaft, carrying a drum, around which, a chain, or rope, is wound, by the revolution of the shaft; the other end of said r0p'e, o"r chain being attached to' any fixed object in advance ofthe machine; which is, consequently, moved forward with a velocity proportioned to the size of the drum. In the rear of the carriage which su'pports'the ma chinery, I place myexcavating wheel, or "ex cavator, by means of which the-bottom and sides of the ditch are to be cut, the earth elevated, and thrown upon an inclined plane, by which it is deposited on the side of the ditch to form an embankment." To this excavating wheel the requisite motion is communicated by gearing from the "vertical shaft which is turned by the horse.
In'the accompanying drawings, Figure 1, represents a top view of the machine; Fig. 2, a side view of the excavating wheel, the'inclined plane, and a part of the carriage; Fig. 3, represents the inclinedrirhs of the excavating wheel, with their cutting edges,
and the vibrating receivers for containing,
elevating, and discharging the soil; the serrated ring I, I, which forms one face of the wheel as seen in Fig. 2, being removed to show them distinctly. It is intended sometimes to omit the serrated rims which constitute the circumference of the wheel, and to use two, or any other convenient number of arms, which are tocarry the cutting edges of the excavation, and the vibrating receivers for the soil; a side view of this modification of the apparatus is shown at Fig. 4, together with the manner of gearing to convey motion from the vertical shaft to the excavator. view of the machine, with the wheels attached to the slides for adjusting the depth of the excavating wheel, like parts in this figure being designated by the same letters of reference as in other figures.

To guide the machine I use two wheels d, it, made thin so as tocup into the ground, their faxle turning upon a center pin, sothat its idirectlon may be changed by moving the lever (l in the manner indicated in the shown in Fig. 2, has a face rim I, I, extend-11 ing inward from the serrated. edge to. such? distance only as is necessary to embrace the receivers for containing the excavated earth. 1 9
placed dipon'the ground; theseways are to be removed and carried forward, as the ma- In this face rim there are openings at f, f, and similar openings on the opposite side of the wheel, each having a cutting edge projecting out along one of its sides, to scrape, or cut, the soil at the sides of the ditch, and allow it to pass into the interior of the wheel, where the receivers are placed.
In Fig. 3, which represents the excavating wheel with the face rim removed, K, K, are the metallic plates which form its outer rim; these as it will be seen, consist of curved segments, which in Fig. 2, are covered by the face rim, in which figure they are represented by dotted lines; 9, g, are their cutting edges, and as these separate the soil, it passes into the vibrating receivers 72., h, h;
' the edges of which, when they are at the lower part of the machine, rest just within the cutting edges of the wheel, and as this rises, the receivers swing upon joint rods 2 '21, z, and carry the earth up until the ends k, k, of the receivers are brought into contact with stops, or pins Z, Z, by which they are made to discharge themselves, the earth falling from them onto an inclined plane, or chuteL, L, (Figs- 2, 5, and 9,) the'lower edge of which plane reaches beyond the excavation, and delivers the earth where it is required to form an embankment. The upper edge of the plane is extended up under the buckets, as represented in Fig. 5, and
supported in this position by the uprights L which rests upon the shaft, or axle C, of the excavator. 1
N is a box placed .in the uprights L through which the axle passesand upon which it wears. The lower end of L also rests upon a part of the frame A, which is here extended into the wheelto receive it.
0 is a piece that extends across the bottom of the plane, and rests upon the top end of the upright.
In Fig. 2, I have represented four cutting edges, and four receivers to the excavating wheel; but this number may be varied as may be found to answer best, and it may probably be found that two will be sufficient. Instead of using a wheel with serrated edges, I intend as already stated, sometimes to em ploy arms projecting out from the main shaft, carrying at their outer extremities,
the vibrating receivers contained within suitable cutting edges, so as to operate in all respects like the wheel described. In Figs.
. 4.- and 5, H, M, may represent such arms,
and m, m, the cutting edges of the excavator; the sheets of metal forming the cutters, must be attached firmly to the arms and may be connected by braces as at n, n.
Fig. 10, represents a perspective view of one of the vibrating receivers,vwith' the lugs and the bolts for adjusting them for differentwidths.
As it is desirable in some soils, to give a greater slope to the sides of the ditch, than in others, I, in many cases, make the cutting sides of my excavator adjustable, by means of a rod'and regulating screws, as shown at 0, 0, Fig. 10, and by the dotted lines 0, 0, Fig. 5. I sometimes also place cutting teeth "1', 7', Fig. 6, along the lower edge, and side,
I of said excavator, and projecting out some three or four inches therefrom, of different forms and sizes, according to the size of the ditch to be out, by which means it will cut more readily through the matted sward, and other obstructing matter. Where the nature of the groundis such as not to afford a firm footing to the horse, I attach a circular platform, or horse walk to the machine, to slide along upon the ground, as shown by the .dotted lines at P, P, Fig. 1, which consequently advances withthe'machine. To adjust the machine to the cutting of different depths,I employ an adjusting screw, g, Figs. 2, 7, and 8, 9, which operates upon the slide a", r, upon which the axles a: m of the wheels that supports the excavator are placed.
Having thus fully described the 'manner in which I construct and employ my machine for ditching and embanking; I' do hereby declare that I claim as my invention,
1. The vibrating receivers, constructed and operating substantially in the manner described, in combination with the cutters. 3 2. The mode of causing the machine to advance, by coiling the rope around the drum and looking it by hand, when it is desired to lessen the motion, as the lever, or sweep is turned, in combination with the excavator constructed as herein described.
3. I claim the attching of the horse walk, or circular platform, to the machine, so as toadvance with it. p V a if 4, I claim the manner of adjusting the cutting wheel, of excavator, so as to cut to different depths, by means ofthe arrangement herein described, that is to say, by attaching the axles of the wheels, on'which the machine rests, to the lower part of the slides which are regulated by screws as herein described.
5. I claim the application of teeth to the 7. I claim the mode of changing the width. of the ditch and the slope of the slide by setting the side cutters to different inclinations as herein described, the whole being constructed and combined as herein set forth.
