To all lwhom it may concern:

Be it known that I, 'JAuJas Bowie, of Triana, in the county of Madison and State of Alabama, have invented a newfandpuse- Yful Improvement in Machines for Excavating Earth, called Roweslnclined Elevating Box-VVheel, which is described as follows, reference. being had to the annexed drawings of the same, making part of this specification.

My machine consists of a large 'elevating Wheel A, Figures 1, 3 and 4f; iedined .et an angle of about fifty degrees, with buckets B, Fig. 3 onv its periphery to receive the earth turned into them by a com-mon plow Z Fi 3 attached to the machine-said wheel, cal ed. the box-wheel, turningon a spindleL, Figs. 3 and 4L, inserted intov the side of;- a rectangular frame which is elevated ,from the ground on one side by saidbox wheel and on the other by a vertical wheel Q, turning on a crank axler on the off side of the frame I, (Fig. 1 ),-said v.framey withV the wheels being drawn forward by a locomotive engine to whichk it is attached, or by animals attached to it-the plow, which. may be of the common bar-share kind being attached to the forward part of the frame on the near side or toward the face. of the box wheel for turning the earth to bey raised, into the bucketsB, (Fig.Y 3) of said boxwheel-or the plow may be such as seen at L Fig. 3, a part of the bottom of said buckets E, (Fig. 1) being movable on hinges for discharging their loads when required and kept closed, whiley being filled by springs S, on the backofjthe same and during theirV revolution and when they arrive at t-he vertex of the curve in which they move are opened by a stationary inclined plane F, fastened to the frame against which, arms, attached to` and projecting from the movvabley bottoms of the buckets, (with or without anti-'friction rollers) come in contact causingthem to open and discharge their: load through the openings which they close' orfcoverf-at the same time contracting the springs; which, as soon as the arms have passed the inclined plane, again close the movable bottoms by their elastic power the earth being discharged into any suitable receiver placed under them, or on to an endless conveying-band, moving over rollers or drums, in the ordinary mode which conveys the earth toa cart, or any other place desired, by means of a connection by band; or otherwise with the hub of the, inclined wheel`or the earth may be Ydischarged upon my patented circular revolving pleasure car-the seatsbeing previously removed torgive room for the earth or by means of a circular revolying platform such as is rep resented; at Fig. '21,' and whenqexcavating in uneven placeshaving the aXleP, Figs. 1, 4, of the vertical wheelso arranged on a crank moving around on an adjusting semi-circular plate T, that the frame and box wheel may beV adjusted to any required angle, by

lmeans ,of an arm U, and pin *orrv key Y.

'n A, Figs. L, t, 3;, inthe annexed drawings represents .the inclined bsox wheel which may be made of cast-iron, or any suitable material; itsv SlZe will necessarily` vary according toA the` purposes to whichV it is applied, K'

The boxes, or bucketsl Bi (Fig. 3,). to re,-` ceive the` earth. are formed around the periphery of said box wheel the partitions C '1 beingl at regular intervals of about two feet more. or less., and the depth and width of the buckets or boxes; may be about equal.

The partitions are brought to a sharpl edge in part as, at Cv Fig. 3' inorder to cut the sod lor clay as it comes from the plowlto admit the earth to pass into the chamber of each box as the wheel revolves. v

lllhe boxes B Fig. 3 are closed or-made Soll a Little more than half their length as at D, and the` remaining part ofthe box 1B, is closed by a movable shutter E either- 'hinged orv sliding, with a catch o r spring. S,

to hold-it closed asv at S, Figs.. 1 and 4c, and astationary double-inclined plane F Fig. l is fastened to the frame to. open them, when each bucket arrives atY the point ofgreatest altitude5-the earth then escapes.

A small rim Gr, Figs. 1 and 4L, projects outward beyond the face of the` buckets to re- .to the` aXle-treeof a wagon, and. hung'at :110

the aforesaid angle. It has projecting centers or hubs K, Figs. 8 and 4, on each side of the box wheel to admit the Vspindle L through a round aperture in the center of the same hub and of sufficient diameter to give the requisite motion to lany convenient conveying vapparatus--by a 'connecting bandpart of which is seen at u Fig..4 and u Fig. EZ-such for instance as is represented at Figs. 2 and 5, and which will receive the1 earth from said inclined box wheel and convey and deposit it where required.

The excavator,or plow proposed to be used is the farmlers common barshareplow, with very little change and variation although any suitable kind of plow may be used. The plow, however, should be built longer, and so constructed as to raise the earth more gradually, and a little higher before it is turned over by the mold-board the beam may be larger andso constructed as to work from et to 8, colters abreast, when necessary, so as to cut up the sod or tough clay, in order to facilitalte its discharge from the boxes. The plow is to be attached to the framing of the box wheel and in a position to work immediately by the side of the boxes of the inclined wheel so as to turn the earth into them with facility.. In front of the boxes of the box wheel is a narrow `rimset obliquely-see Figs. 3V and 4.

Y ranged the locomotive Vor team moves forward-the plow turns the furrow or fur` rows over a small rim X Figs. 3 and 4 in front of the boxes of the inclined wheel into them. The traveling or onward motion of the box wheel elevates the earth to the apex of the curve in which it moves. The stationary fixture Vor double inclined plane opens the gates, doors, or shutters, and the discharges take place at one point, by means of the arms coming in contact with said inclined plane. A chute constructed to receive the earth and convey it to one point is recommended to be used. And by means of simple fixtures well known to mechanics the earth may be conveyed to the right or left any distance required for the construction of roads, streets, &c. The before described box wheel may be attachedV to the Ynecessary framing of the machine, as one of the traveling' wheels, or it may Vbe appended as an extra.

A simple mode of constructing the frame Y is by having a strong, straight beam of tim-V ber t, Figs. 3 and 4. VAbout the center of this timber the box wheel is hung on a strong axle L, Figs. 3 and 4. On the opposite side'of this timber t, `from the box wheel there is framed a parallel piece N, (Fig. l) and on the front end of the frame is a shaft O, Figs. l and 4, andon the end of said shaft immediately outside the frame the shaft turns at right angles and then again at right angles and forms a crank P, Fig. 4, the last mentioned turn being formed into a spindle P', on which wheel Q, is placed, designed to balance the box wheel and support the opposite side of the frame from that on which the inclined wheel is placed. On the shaft is fastened a right-angled arm U moving against a semi-circular plate T (the side view shown in Fig. 4, and the front View in Fig. 1,) pierced with apertures and fastened to the 1 frame, said arm being pierced with corresponding holes through which a key Y, is inserted to fasten it at any angle required, in order to raise or lower the side ofthe frame for changing the inclination of the box wheel. In y front of the wheelthere is a strong arm V, Figs. l and 3, connected to the main beam, to which arm the plow is fastened or attached. The end of the main beam is tenoned as at W (Fig. 1) likewise pierced with a holeto attach it to theaxle of the front wheels of a common wagon.

Manner of usc' g the ma0hz'nc.-For the various kinds of ditching, and the formation of a levee, no appendage is necessary to the inclined` box wheel, except a simple chute s, Fig. 5, to convey the dirt to the levee. If the excavated earth isdesigned to be moved, the only appendage necessary in addition to what is described is a wide belt b, formed on any of the endless chain plans passing around two pulleys p, p, and motion given from the hub at the center of the box wheel by a continuation 0f the band in Fig. 4, or it will revolve from the gravity of the earth, and the left end of the belt is sufficiently elevated for dirt and wagons to pass under and receive the earth. Or by lengthening the belt the dirt may be conveyed from the side cut to the center of a street or road, or a large horizontal wheel fw, Fig. 2, may be hung on an axle and motion given to it, as before described, by placing this wheel below or on a line with the center of the boxwheel; then, by means of an inclined apron collect the dirt on this wheel, and by its motion it is carried around and by a stationary fixture it is pushed off at any point desired. 'On this plan the box-wheel will do a fair business without, the use of the doors and springs, which may be wholly dispensed with. By this machine and fixtures carts and wagons may be lled with astonishing facility wherever the plow and cart can be worked, and as much earth can be thrown up by a single team and two hands as by fifty hands in the ordinary mode.

For plowing both ways and forming an embankment on one side only, I recommend my circular rail-roadl and continuous car to be mounted on the framing of the excavating machine and to be driven by a band leading to the hub of the box wheel.

By dispensing withthe seats of the car it may be made an eiicient agent to convey the dirt to an embankment.

The advantages of my improvement over others of the kind are: l. It receives the earth directly from the plow almost entirely Without Waste and elevates it to any convenient height, and delivers it Without Waste to other agents such as are represented at Figs. 2 and 5, by Which it is con veyed and deposited into carts, as from the side ditches of streets, or roads to the center, or from the center of canals, forming embankments 4on each or either side. 2. From the simplicity of the machine it is not subject to derangement; and its cost will be comparatively small.

The invention claimed by me, the lsaid arrangement of these parts, substantially in the manner above described.
