FERTILIZER-DISTFH BUTEFL` Patented Nov. 20, 1906.

To 11]/ n'lm'llt lmuy concern.:

Be it known that I, WILLIAM J. ELsoM, of Cortland, in the county ol` (ortland, in the State of New York, have invented new and useful ,Improvements in Fertilizer-Distributers, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

'l`his invention relates to the class of fertilizer-distributers in which the vehicle which carries the fertilizers is provided with a lon- `itudinally-movable a )ron in the bottom of the \v*ehielebody for the purpose of moving the fertilizer to the distributing rear end of the body and which apron is subsequently reversed in its movement to return to its normal position for receiving another supply of fertilizer.

'Ihe chief object of this invention is to provide the machine with suitable means for automatically arresting the movement of the apron at its loading position .in the body and' at the end of its discharging position; and to that end the invention consists in the novel construction and combination of the compo nent parts of the arresting mechanisms and auxiliary devices employed in connection therewith, as hereinafter described, and summed up in the annexed claims.

In the accompanying drawings, Figures 1 and 2 are elevations of opposite sides of a fertilizer-distributer embodying my invention. Fig. 3 is an enlarged view of the mechanisms which transmit motion to the apron, shown partly in section. Figs. 4 and 5 are longitudinal sections of the apron in its positions at the beginning and end of its rearward movement. Fig. 6 is a rear end elevation of themechanisms for transmitting motion from the beater-shaft to the rear shaft of the chain'- wheels which carry the apron. Fig. 7 is an enlarged plan view of the clutch mechanism which controls the movement of the apron, and Fig. 8 is a fragmentary face view of the gear-wheel which is adapted to transmit variable speed to one of the mechanisms which actuate the apron.

A denotes the body of the vehicle which carries the fertilizer to be distributed upon' the field.

B is one of the rear traction-wheels of the vehicle.

C is the longitudinally-movable apron or bottom of the. body A, which apron is in the present ease of a slightly greater length than the body A and has mounted on its front end the follow-board D. (Shown in Figs. 4 and 5 of the drawings.)

a, represents one of the endless chamshto which are attached the transverse slats which form the apron.V

l) and b are the wheels upon which the chain (1I is carried. The rear Wheel b is fastened to the transverse shaft b2, which I term the apron-shaft, while the front Wheel b is mounted loosely on the shaft b3.

The apron C is required to travel back and forth to discharge the fertilizer at the rear end of the body A, as represented in Fig. 5, and then return to a osition to serve as the bottom or floor of said body preparatory to loading the body with fertilizer, as shown in Fig. 4. To automatically arrest the movements of the apron at its arrivals at its extreme inner and outer position on the machine, I employ mechanisms which are actuated by the travel of the apron, as herein presently explained. l

The forward movement of the apron C to a position to close the bottom of the body A, I derive from the shaft c of the beater F, which has a rapid rotary motion transmitted to it by means of a gear-wheel Bl actuated by the traction-wheel B, preferably at the left-hand side of the machine, as shown in Fig. 2 of the drawings. The said gear-wheel meshes with a pinion B2, which is fastened to or formed in` tegral with a sprocket-wheel B3, mounted on a stub-shaft c', projecting from a suitable bracket (not shown) attached to the side of the body A. A smaller sprocket-wheel B4 is attachedto the beater-shaft c and connected with the sprocket-wheel B3 by a drive-chain c2.

At the right-hand side of the machine are two sprocket-wheels d d', mounted loosely on the shaft b and disposed a sufficient distance apart to admit between them a duplex clutchcollar e, which is mounted movably on the apron-shaft b and is provided internally with a longitudinal groove engaging a spline e3 on the shaft. The clutch-faces e e2 on opposite ends of the collar e are formed reverse to each other and adapted to -engage one at a time the clutch members e4 and e5, formed on the sides of the sprocket-wheels d and d', respectively. A central positon of the clutch-col- IOO the end of the shaft b.

lar e between the said clutch members prevents engagements of said parts, and thus the clutch-collar and apron-shaft remain at rest. At the same side of the machine the beater-shaft c has attached to it a gear-wheel f, and parallel with this shaft is a stub-shaft c', on which is pivoted an eccentric c2. (Shown in Figs. l and 3.) Upon the hub ol' this eccentric is revolu bly mounted a gear c, to the side of which is rigidly secured a sprocket-wheel c4, connected by drive-chain c5 with the sprocket-wheel l on the apronshalt b, as shownin Fig. (i. By turning the eccentric c2 the wheel c is thrown in and out of gear with the wheelf, and thus the motion ol' the sprocket-wheel d is controlled. The said turning of the eccentric is ell'ected automatically, as hereinafter described.

For iin parting rearward movement to the apron C, I preferably employ mechanisms similar to those shown in the Letters Patent No. 789,498, dated May 9, 1905, which consist of the disk or annular plate 0, mounted on the axle '.l of the rear traction-wheels B and rotating with said wheels. Theinnerface of the said disk has projecting from it concentric rows of teeth t t, which rows are arranged with blank annular s aces t between them, as shown in Fig. 8 o the drawings. Radially across the toothed side of the disk O is a shaft g, whlch is pivoted at opposite ends in bearings secured to a bracket I, firmly attached to the side of the body A.

On the shaft g is mounted a pinion i, which is movable lengthwise vided in its hub with a longitudinal groove which engages a spline on the shaft. By slidin the said pinion toward and from the aXis o the disk O it is caused to engage different rows of teeth t, and thus vary the speed of rotation of the pinion. This shifting of the inion is effected by means of a hand-lever?, ivoted to the front portion of the body A an connected by a rod t" to one of the arms of a bell-crank 112, whose other arm is bifurcated and connected to trunnions on a ring j, seated loosely in a groove in the hub of the pinion i, as shown in Figs. 1 and 3 of the drawings.

To the outer end of the shaft g is fastened a worm g, which engages a gear g2, mounted lon a stub-shaft g3, projecting from vthe bracket I. To the side of the gear g2 is fastened a sprocket-wheel g, which by a sprocket-chain g5 is connected to the sprocket-wheel d on 'This sprocket-wheel is thus revolved reverse from the sprocketwheel d on the said shaft. When the clutchcollar e is in engagement with the clutch member e4 on the wheel d, the shaft b is turned in a direction which causes the a ron C to travel forward, which movement 1s derived from beater-shaft c by the mechanisms hereinbefore described, and thus the apron C is moved at a considerable speed to position to vsecured to the body A.

thereof and` is pro-` close the bottom of the bod A. By then shifting the clutch-collar c to its neutral position the apron is left-in said position'.

'lhe shifting of the clutch-collar e to its neutral position is effected automaticallyby the movement ofthe apron through the instrumentality of two trip-levers lr and k', pivoted to the body A respectively at land l', as shown 'in Figs. l, 4, and 5. 'lhe trip-lever lr is located at the front ol' the body and extended upward l'rom its fulcrum to render it conveniently accessible for thc operator or driver of the machine to rest-ore said lever and its cooperating lever lc to their required position for being actuated by the traveling apron. The trip-levers c and r are connected to each other by means of a rod Z2, so as to operate in unison. At a suitable distance from the rear end of the machine is a rockshaft m, mounted in bearings on the body A, as shown in Fig. 7 of the drawings. To this shaft is attached an arm'm, which is connected by a rod m2 to the tri p-lever c. lo the outer end of the rock-shaft m is ri idly attached a collar n, which is provide( with a fixed crank n and with a circumferential groove n2, which extends obliquely around the collar. The said crank is connected by a rod 0 to an arm o, which projects laterally from the eccentric c2.

A lever p is fulcrumed at or near the center of its length on a bracket 7)', which is rigidly Each end of said lever is bifurcated and rovided on the inner sides of the prongs wit lugs r r, as indicated by dotted lines 1n Fig. 7. The lugs' of one end of the lever 7) engage the groove n2 in the collar n, while the lugs of the opposite end of the lever engage a circumferential groove p? in the clutch-collar e.

The operation of the machine is as follows: The apron C being in position to form the bottom of the body A, as shown in Fig. 4, and loaded with the fertilizer, the operator moves the lever J into a position which throws the pinion i out of engagement with the teeth t of the disk O, and thus leaves the apron C dormant in the aforesaid position during the time of taking the machine to the field designed to receive the fertilizer. The beater F is also retained at rest during said time by the operator setting the lever L into a position which throws the gear-wheel B out of engagement with the traction-wheel B by means of suitable clutch mechanism actuated by arod s, connected to the leverL. (Shownin Fig. 2.) The said clutch mechanism may be of any suitable and well-known construction. When the apron C is in the aforesaid position, the bracket u,which supports the follow-board D, presses on the end of an arm u', attached to the trip-lever lr, above the fulcrum thereof, as shown in Fig. 4. Said pressure throws the lever 7c to a position whlch causes the lower end thereof to push the trip-lever c into a ICO essen l rearwardl 't-iiiclin'ed position by ineens of the rod l ax atthe same time causes the rod m to push the carryr the lugs r r lof the front end of the lever p midway in the diagonal groove n of the collar n, and thus 'cause the opposlte end of the lever p to collar is retained while the machine loaded with fertilizeris conveyed to. the'eld in which the fertilizer lis to be distributed.

Upon its arrival thereat the operator sets the levers J and L in positions to transmit motions from the disk O to the loosely-mounted n sprocket-wheel d and from the tractionwheel B on the o posite side of the machine to the beater-sha t and thence Ato thelooselymounted sprocket-wheeld'. :Then the oper-v ator resses by his foot the upper end of the tripever Ic farther .forward om where it was left bythe pressure applied to the arm Iu. by the bracket u. The said further thrust of the lever k throws the clutch=collar e into engagement with the clutch membere5 on the sprocket-wheel d', and thus causes said wheel the apron to impart motion to the shaft' b, which moves C rearward to discharge the fertilizer through the rear end of the body A. In said movement .ofthe apron it becomes inverted at said end of the body, and the vinverted portion is carried forward beneath the body A, where the front end oflsaid inverted apron comes in contact with the trip-lever` k as shown in Fig. 5, .and 4pushes the same mto a forwardlyfinclined position at the time when the entire load of fertilizer .has been discharged from the body movement of the trip-lever 7c tilts the arm mvforward by means'of the rod m. This: tilting of said arms turns the collar 'n so as to cause it to push the lever p into a position which throws the clutch-collar 'e out of ention of the apron.

gagement with the clutch member es and into 4. and thus arrests the moits neutral' position,

The operator then, by means of the trip-lever c, moves the rod m2 to turn the collar 'n so .as to cause the lever to throw the clutch e into engagement wit the wheel d, which receives acomparatively rapid motion from the beater-shaft and returns the apron C` to its original position in thebody A. In arriving'V at said position the apron is again arrested by the hereinbeforedescribed action of the trip-lever k, which again shifts the clutch-collar e so as to re- 'l lease both clutch .members Aof the sprocketthe pinion c3 fon the beater-shaft c. ready to be started with another load of fer? wheels d and d. Simultaneously with this action the crank n on the'grooved collar n turns the eccentric c2. suiiciently to throw out of engagement with the gear The achine is then meer to the-eeld/uon which it is .to be distributed.
