The arm H extends forward, while the other arm 11 exlends rearward, as is plainly illustrated in Fig. 5. The free end of the arm II is connected with the end of a chain 11 and the arm 11 is connected with a chain H both extending upward, the chain 11 passing overa pulley ll, held on the main frame A. The chains ii and I] then pass over two pulleys II", mounted to fotate loosely on the shaft E". previously mentioned. The chains 1-1 and H extend rearward from the said pulleys 1-1 to wind on the two drums I and 1', respectively, secured on the shafts I and 1 respectively, arranged vertically and mounted to turn in suitable bearings in the cross-beam of the standards A in the main frame A. I

The shafts I and 1 are provided with handwheels '1 and 1 respectively, under the control of the operator standing on the platform A. The upper ends of the shafts I and I carry ratchet-wheels I and O ,engaged by pawls 1 and 1, pivoted on the cross-beam of the standards A as is plainly shown in Figs. 1 and 3. By the operator turning the shaft 1 by means of the hand-wheel I a pull is exerted on the chain I l, so that the cross-bar H is pressed downward, thus exerting pressnre onthe spring I], and thereby forcing the front end of the plow downward in firm contact with the ground to be taken up. A similar pressure may be exerted against the rear of the plow D by the operator turning'the shaft I so as to wind up the chain if and its drum I. It will be seenthat by this arrangement the plow D is yieldingly mounted so as to readily pass over any serious obstructions in the ditch-bed.

The rear upper end of the bottom D of the plow D discharges onto an endless carrierbelt J, passing over the rollers J and J secured on shafts J and J,of which the former is journaled below the bottom I) in the sides D of the plow D. The shaft J is jourualed in the belt-frame J, secured at its upper end to the frame A and pivotally connected at its lower end by links J with the shaft J, previously mentioned. The links J permit of raising and lowering the plow D without changing the position of the carrier-belt J relative to the discharge end of the said plow l). The upper end of the earrier belt J discharges onto a second carrier-belt K, arranged transversely and passing over rollers Kaud K jourualed in a transversely?cxtcuding frame K, secured on the main frame A. The roller K is located to one side of themain frame A, as is plainly shown in Fig, 4, and the belt K discharges over this roller K onto the secomltransverse' carrier-belt L, intended to carry the material to one side of the machine any desired distance. The endless belts K, J, and L are actuated simultaneously from the rear axle C when the machine is moved forward.

In order to impart a traveling motion to the inclined belt J, the shaftJ' is provided on one end with a sprocket-wheel J over which passes a sprocket-chain N, extending rearwardly and downwardly and passing with its lower part o y nr' an idler N, supported from the main frame A The rear lower part of the spiocketchain N passes over a sprocketwheel N secured on a transverse shaft N, mounted to turn in suitable bearings on the rear part of the main frame A.

On the shaft N is secured a pinion N'Yin mesh with a gear-wheel N, mounted to 1'0- tate loosely on the axle C, carrying thehind wheel C. On the hub of the gear-wheel N are formed clutch-teeth adapted to be engaged by a clutch N, held to slide on and to turn with the said axle l. The clutch N is engaged with the lower end of a shifting 1ever N", pivoted on the main frame A and extending through the platform A, so as to be within convenient reach of the operator standing on the said platform A \Vhen the lever N is shifted so as to engage the clutch N with the clutch-teeth 0n the gear-wheel N, then the latter rotates with the shaft 0 when the machine is dragged forward. The gearwheel N imparts a rotary motion to the pinion N so that the shaft N is rotated and the rotary motion of the latter is transmitted by the sprocket-wheel N and the sprocket-chain N to the sprocket-wheel J, whereby the shaft J is rotated and rotary motion is imparted to the carrier-belt J in the direction of the arrow a.

On the shaft N is secured a bevel-gear wheel 0, meshing into a beyel gear wheel 0, secured on a longitudinally-extending shaftmounted to turn in suitable bearings in the main frame A and carrying on its inner end a sprocket-wheel 0, over which passes a sprocket-chain 0, also passing over a sprocket-wheel O, secured on the shaft K" of the roller K. Thus when the shaft N is rotated, as previously described, the gearwheel O imparts a rotary motion to the gearwheel 0, thus rotating the shaft 0', which by the sprocket-wheel O, the sprocket-chain O,and the sprocket-wheel O imparts a rotary motion to the shaft K", so that the carrier-belt K is caused to travel in the direc iionof the arrow 7;. ()n the innerend of the shaft is also secured a sproeketwhcel 1, over which passes a sprocket-chain 1", extending transversely and passing over a sproeketwheel 1", secured on the shaft L, ,earrying the roller I), over which the carrierbelt L passes. The latter also passes over the inner roller L, journaled in a frame L,which also supports .the shaft L. \Vhen the machine is dragged forward, the rotary motion ofthe shaft 0? causes the sprocket-wheel l to rotate, seas to impart motion to the sprocketchain P, which by passing over the sprocketwheell" rotates the shaft L, thus imparting a traveling motion to the carrier-belt L in the direction of the arrow 0.

The frame L supporting the carrier-belt L,

is provided near its in'iir end with longitudion itsirrner end, the outer frame A.

On the rear end of the shaft R is'secured a hand-wheel R within convenient reach of the operator standing on the platform A. A ratchet-wheel R 'is secured on the shaft R? and is adapted to be engaged by a pawl R to prevent a rotation of the shaft R and a consequent unwinding of the chains R and R, e and thus holding the free endof the frame L? in theproper position. v

- YVhen it is desired to shift the carrier-belt l farther to one side of the machine, the op-.'

erator moves the bearings Q on the guideways Q, so that the frame L slides outward to one side of the machine, carrying the carrier-belt- L along. At the same time the operator turns the shaft B so as'to let out the chains R and R to compensate for the outward movement of the carrier-belt frameL The latter can be raised or lowered at its free end by winding up or unwinding the chains R and R on 1 the drums R In case the frame L, with the carrier-belt L, is-moved outward, the chain 1 has to be-lengthened by adding the necessary number oflinks. Instead of. doing this, however, the chain 1 may :be' entirely-disconnected from the sprocket-wheel P and passed over anothersprocket-pulley, also driven from the shaft 0 The latter, is for. this purpose provided with a sprocket-Wheel S, over which passes a sprocket-chain vS, extending transversel y and passing'over a sprocket-wheel S secured on a shaft S mounted to turn in suitable hearings on that side of the main frame Aon which the carrier-frame is extended.

' ()n the shaft S is secured a sprocket-wheel is passed. When the machine is moved forward, the shaft S is rotated from the shaft 0 so -that.a travel- Jing motionis imparted to the sprocket-chain P, and by the latter movement is imparted to the carrier-belt L in the manner previously described.

In order to clean or scrape off the plow D,

a scraper T is provided, whichextends transversely over the bottom D of the plow between the sides D. The scraper T is rigidly secured to an upwardlyextending arm T, pivotally connected with a lever T fulcrumed loosely on the shaft E, previously mentioned. The free end of the lever T is guided verti cally-in guideways T erected on the front end of the frame A at the'side of th driversis within seat A, so that thesaid lever T convenient reach of the driver, who by pressfront end .under side of the axle ing down the said lever T with the inclined bottom D of the plow D. As the scraper T is slightly curved, as is plainly shown in Fig. 5, the said scraper moves forward, thus scraping off any dirt adhering to the bottom or sides of the plow.

In order to prevent the front wheels B from sinking too deep into the loose ground, two V-shaped plows U are mounted in front of the said wheels, so as' to make a furrow to permit the said wheels to travel on hard ground. The plows U are secured on the of a frame U, pivoted at U to the I B The free end of the frame U is also connected by a rope or chain U with one arm of, a bell-crank lever U, pivoted on the-drivers seat A and under the control of the driver seated on the said seat A". The lever U is also under the control of the operator standing on the platform A For this purpose the said lever is connected with a rope or chain U extending rearwardly and adapted to be fastened atits rear end on a cleat or pin U.

The. operation is as follows: The machine is drawn over the ground to be ditched in a suitable manner, the point of the plow D passing into the ground, so that the latter is plowed up, and passes over the inclined bottom of the plow onto the .lower end of the traveling or carrier belt J, which elevates the earth and finally discharges the same onto the transversecarrier-belt K. The latter discharges at the rear on one side of the machine onto the carrer-belt L, which carries the earth to a suitable distance to one sideof the machine to finally discharge the same over the roller L It will be belt L can be moved seen that the carrierto one side of the maend of the belt K will still discharge onto the belt L in casethe carrier-belt frame L is moved into an extreme outer position. When the operator desires to press the point of the plow farther into the ground, he turnsthe hand-wheel I so'as revolve the shaft .1 to wind up the chain ll on the drum 1'. The chain II now pulls on the arm 11*, which latter presses on the bar 11 thus compressing the spring II, and thereby exertingapressure onto the front end of the plow, so that the latter swings downward, the operator at the same time giving considerable-slack to the chains E by unwinding them from the drums F on the shaft F.

engages the scraper The plow may be raised I chine to,a considerable distance, as the rear entirely out of the ground whenever desired lever F and the hand-wheel G so as to wind up the chains'E and E.v VVhenthe plow'is raised, the lower end of the carrier-belt J is also elevated so as to be off the ground as the shaft J of the said belt is the sides D of the plow. The operator can stop thebelts J,K, and L from traveling at any time he desires by operating the lever N so as to throw the clutch N out of mesh with the clute'heteet-h on the gear-wheel N. "The opmounted to turn in.

, by the operator working simultaneously the I erator can clean the plow by the scraper T iat any time whenever found necessary. Thus it will be seen that the several working parts of the machine are under full control of the operator.
