.FERTILIZER- DISTRIBUTER.

Specification of Letters Patent.

Application filed August 21, 1908. Serial No. 449,698.

Iowa, have invented certain` new and user-ullmprovements in Fertilizer-Distributors, of which the following is a specification.

My invention relates to improvements in fertilizer distributers, and the objects of my improvements are these: First, to provide suitable'mechanism for returning` the conveyer-apron to its initial position when it has arrived at its limit of discharging movement; second, to furnish means for horizontally adjusting the spacing apart of the Vdriven gear on the ends of the transverse operating-shaft in order to accommodate` the i m to any one ot various widths of wagon oxes or runninggear; third, 'to supply automatic means for stopping the movement of the conveyer-apron when it has arrived at the limit of its dis- 'eharging movement; fourth, to use suitable adjustable means for tightening up the con-- Voyer-apron; and lilith, to variously adapt said improvements to he conveniently used in connection with special mechanism adaptof the machine. achieved by the mechanisn'i and means which are hereinafter fully described and claimed, and which are illustrated in the accompanying drawings, in which;

' of thefconveyefl Figure lA is a right-hand side elevation or 'diagram of a' fertilizer distributer equipped with my said improvements. Fig. Q 1s a left-hand side elevation of the same. Fig. 3 p

is an enlarged detail of the shifting-mechanism for the slide-clutch on the right-hand end of the transverse operatingshaift. Fig. 4 represents enlarged details of the :nfljusti1 )'-means on the rigl'it-l'land ond of, the ing-shaft with the various sprocket- ,vhec driven by sa id shaft. Fig. 5 is a side `elevat )met the conVoyer-apron adjustable tightening-minns. F G is a perspective ot' one oil thel upportino brackets 'for said tighteningmeans.`\l`"ig. i is a plan View of the forward end oil-| the.shittingl arm 'for the said slide-clutch. Fig. 8 is. oit the part depicted in Fig. 7.

Similar numerals refer to similar parts throughout the several views.

The \w.gon-hox'34A is connected to and supported by the parallel longitudinal sidebeams ll. 'lhosaid beams rest on holsters, which in turn are supported by the front and rear axles of the front and rear carrying-wheels 107 and respectively. The 'forward part of the frame of the box 3ft is undercut lo allowY of the clearance of the front-wheels 10'( in moving thereunder in turning the vehicle about. The rear end of the box is closed, while a distributor-drum 18 is secured to a transverserotatable shaft 20, the latter'being mounted about intermediately between the frontand rear-carrying Wheels, but the drum Workingl in the open front end of the box. The saiddrum is adapted to be rotated forwardly, so as to eject the contents of said box beneath it and just to the,rear of the front-carrying wheels.

The box 34- conlains a movable ('.onveyerapron, composed of transverse parallel slats 3h seoured at. each end to parallel longitudinal endless sin-oclurt-chuins ,111. The chains are carried under the rear end of the box on sproclwt-idlers :lli mounted on the ends of a transwrse rotatable shaft 35, the ends ot' the latter being' mounted in bearings 94 on the rear ends of iuljustable bracketplates 37. Each'plate 37 is scoured to the Wagon-box by a bolt passed through the Wagon-box, then tl'irough a spacing-block 9i, then through said plate and secured by a nut 95. The bolt 92 referred to passes through the plate 37 by way of a longitudinal slot 9G, the latter permitting longitudinal adjustment or' the plate along` the block. The fomvard end of the plate 37 has a flange 108, with a notelied seat 97 in the upper edge o'lfthe latter lor a horizontal bolt 90, the rear end oi the latter being` threaded to receive a nut $3, and said bolt being passed through a horizontal` orifice in the block Sil. ly this moans the shaft is supported, and the latter may ,be .shifted longitudinally by turning the holt 90, 'when it is desired to tighten the conveyerchains 111. The for Ward ends ot the. chai ns lll are passed over 30 the conveyer-apron 38, and has its outer end and at its rear end to said lever 61.' The hand-lever 41 may be shifted an appropriate distanceforward= or back to cause the members 114 and 115 to contact withv and lift toa desired degree the driving-pawls 5() and 52' so as to correspondingly vary the length oftheir driving stroke on the ratchet-wheel. When the members 114 and 115 are moved forward to the limit they lift the pawls away from the'teetli of the ratchet-wheel, which causes the latter to come to a stop.

The drivingpawls aforesaid may be caused to become disengaged automatically from theteeth of the ratchet-wheel by 'the following means, when the pusher 16 of the conveyer-apron 38 has arrived at the forward limit of its course. A slideway 48 is attached to an upright 13 Secured to thelefthand' side of the wagon-box. A slide-bar 44j, whose forward end is pivoted to the handlever 41 at 43is adapted to slide horizontally through said slideway. The rear free end of said' slide-bar has a Islot 117 through which a bolt 53 is inserted and' secured through a slide-head 54. By this means the length of said slide-bar may be varied' to a desired adjustment. The numeral 65 desifrnates a contact-arm which projects laterally from the pusher 16, the latter being connected to without the box bent downward so as to enter' the. plane of movement of the slide-bar 44. Then the conveyer-a 'ron 38 has moved forward to the end of its orward course, the

rejection 65 has contacted with and pushed orward the slide-bar '44 with the hand-lever 41, the connecting-rod 4G and the lever ($1, and so caused the members` 114 and 115 to lift the driving-pawls and stop the, movement of the ratchet-wheel and the apron. ln moving forward, the catch 99 of the lever 41 clicks over the teetl1 100 of the` rack 42, and becomes seated between such teeth at the end of stroke, thus holdingr the pawls away from the ratchet-'wheel-L- I have adopted a device for moving backl the conveyor-apron as. follows. bell-crank lever Q1v is fulerumed on the right-hand end* ofthe shaft The forward member of saidl'ever is pivoted atlOl to the rear' end of a` connecting;- rod 9 whose forward end is likewise pivoted at 10 to a lever'S. The'lever 8 is-pivoted at its lower end on a studv 12 projecting" from the-frame 11, andv has' `a pedal at its Lipperend` for the use of the operator.

The rear member of the bell-crank,leverA 21y has a longitudinal slideway T3 adap'trtlto receive an" adiustabl slide 70, the latter be- Zontal `bracket bearing;v for said idler, said ing slotted at`71 to receivea bolt. 72 extending" from saidrear member. '.lhe slide 7() has' a transverse bearing-orifice 1n` winch is seated' a laterally-adjustable pivot-shaft 25 and the latter'is seeurlf to said slide by a v Set-screw 82.` A hub 1li carrying'` separated sprocket-wheels 69 and" 26 is rot-atably mounted on said shaft 25, and a. sprocket- .cham 24 operatively connects the sprockets 69 and:y 22. The sprocket-wheel' liesl in the plane of the sprocket-chain 17 and'- below it, and may be shifted upward intol operative engagement with said chain 17, when the lever 8 is thrust forward.l When thefoot of the operator is removed rom the pedal of' the lever S, the weight of the mechanism connected to the rear member of the lever 21 lwill cause the sprocket-wheel? to become discause the members 114 and 11I5xto drop from wheel to be driven with the conveyer-apron i forward.

The hand-lever 2, which-is` pivoted to boxat 5 and works in the" rack-4*, is also pivotally connected: at 6 to tlie forward end of the eonnectin'frlrod 7,- whose rear endI is pivoted at 14 to Ztzhe crank `on the rock-shaft 15, and when said liand-lever 2 is shifted forward, the' rock-shaftis turned to throw inward the upper end of the lever 17,-which causes the'- latters fork 28 to move the hub 68 outwardy and thusdisengage the teetlr of said hub from the teeth on the outer face of the sleeve 80., The sproeket-wheelBO then becomes idle on the shaft`29, and the rotation of the distributilig-drum 18 and the movement of the apron are stopped; When the lever 2 is 'thrown backward',` the alcove described process is reverse/di7 andthe drum 18 again set in rotation.

The adjustability of the sprocket-wheels on the. shafts Q9, 25, 23 and 20 as shown, laterally, permits of the use of .the mechanism with boxes of different widths, or earrying-wheels (litlerently spaced apart.

the

l Ots The forward part of the wagon-box is closed by a rearwardly-projectingscreen 3 to protect the drivers seat 1 from Imaterial thrown to the Jfront bythe distributingdrum 1S.

Having described my lnvention, what 1 claimas new, and desire to secure by Letters Patent, is:
