' fodder and Iother farm products from the field, in stacks, barns' and other storage places.

The objects of' my invention are- First, to provide a durable,eflicient and convenient conveyer and stacker which may vao be easily and cheaply constructed and transported from place to place about the field;

Second, to provide the platform which revolves with a hollowmast having pivoted,

` adjustable, oppositely disposed booms. with to turn the booms on their rigging adapted pivots. e

Third, to provide within the mast a tube which shall be rigid with the vehicle, and extend above and beyond the'upper. end of'A the mast, and having abar with a cap movable in the upper portion of the tube, the

cap carryinga 'plurality of pulleys to receive and direct cables employed in operating the boomsgand fourth, to vprovide `the platform which revolves, with a pinion adapted to en. gage the rack mounted on thevehicle and impart motion to the revolving platform.

I attain these and other objects by means *of the mechanism and combination of. parts illustrated in the accompanying drawing in which Figure 1, isa side elevation of the conveyer and stacker, partlyv sectioned to show the method of mounting the operable parts on the vehicle;

' Fig. 2, is a plan view from the top of the hub, 'and showing the integral arms which support the rack; y

` Fig.'v 3, is a sectional view through the operable parts of 'the device on the line X-X, in Fig. 1, the booms and rigging being omitted; V

Fig. 4, is a top; plan view of the boom and the ring with pivots, upon which pivots the booms turn; l

Fig. 5 is a bottom kplan view ofthe cap on the top of the mast and which provides 'a bearing for the inner tube;

Fig. 6, is abottom plan View. of the Cap on the top ofthe inner tube and the pulleys carried thereby, and 4showing the bar integral with thecap vin cross section, and

Fig. '7, is' a top plan view'offtlie revoluble platform, and sho'wing'the stationary platform surrounding the same.

Similar numerals of reference refer to corresponding parts throughout thel several views.

Referring to the drawings-the wheels `1 axles 2, beams'. 8, cross-ties 4, and the' ole #5,.

constitute thee-Vehicle Whih iS Provi ed to SUPPO al1-Cl transport the Organized mechanism which willv be `hereinafter fully eX? plained. A hollowhub 6, is provided ciry cumferentially adjacent its lower 'end with a plurality ofl upwardly and outwardly eX- tending'integral arms 7, havingequalradius, the endsy of the arms` are `flattened to form a seat 8, adapted to lodge on the upperside ofthe beams andjcross-ties and tol receive a piece of mechanism, hereafter described. The upper end portion ofthe hub is. broad cned andthe top end of the hub is machined to provide a substantially' Hat surface to form a'slid'e bearing 9. lAn annular rack-10 ijs provided with c-,ogs 11, and lodged yon the upper side ofthe seats 8 and fixed' thereto by bolts'12, which pierce the rack and seats and penetrate, theb'eams and cross-ties. i

A circular platform 13;, is provided on its upper side with ay centrally disposed ,boss 14, hating a hollow core 15, ada ated to lregister with the hollow core of thel hub. IAn annue. lar channel 16j, is formed inthe boss, the. lower side of the platform beneath the boss is surfaced and adaptedy to bear on the slide bearing 9. A tube 17, is inserted in. the

hollow cores ofthe boss on the platform andy the hub, so that the lower end ofthe tube shall lie substantially in the plane of the lower end of the hub.y A bar 18, inserted upward-ly 4in the tube 1:7', for the purpose of adding strength and rigidity'to the tube and-the parts assembled therewith.` A pin 19, isfextendged through the lower' ends of the hub 6,tube 17 and bar 18, to hold the parts mentioned in place.

A tube 20, 1s positioned over the tube 17,

' 'and its lower end is entered in the channel 16 in the boss '14., which provision assuresl the on'the top'v end of thetube 2K0.L A cap`23, having oppositely disposed lugs 24, supporting pulleys 25, and a downwardly extending` bar 26, fixed to its inner side and projecting into the tube 17, is movably lodged on the top of said tube.

A'ring 27, adapted to fit on the tube 20, is provided with oppositely disposed horizontal pivot pins 28, and with oppositely disposed lugsl29, carrying pulleys 30, is slidably mounted on the tube 20,'and for the purpose of detaining thejring at any place on .the tube, set screws 31, are extended inwardly through the ring, so that 'the points of the screws may have opportunity to impinge on the ,tube to hold the ring in place. Booms 32, are. preferablymade of strips 33, assembled in pairs, the one of which, is positioned so as to overlap the other ofthe pair, thereby providing forthe lengthening or shortening of the boom.

.The overlapping and overlapped strips are heldin place by a clamping device 34, which,f,when loosened, permits the sliding adjustmentv of the boom. The `assembled vstrips invpairs, as described, are beveled at their vouter ends land secured together by fastening devices 35, and an eye 36 is attached to the joinediends of the strips. A pulley 3,7, is mounted between the strips a vlittle distance inwardly of the said end. A pivot bearing is apertured .in the free ends of the side members of thev booms and adapted to receive the pivots 28. A cotter-pin v38, is extended through the end portions ofthe respective pivot pins 28, outwardly of the'booms, for the purpose of holding the booms on the pivot pins. YA set screw 39, is extended through the wall of the tube 17, and is adapted to impinge upon the bar 26, so that if the bar is raised to increase the height of the mast, the set screw shall operate to hold the bar aloft.l The bar i. 26,'normally ishoused in the tube 17, and

is turned in the turning of the booms. A narrow circular platform 40, surrounding the revoluble platform 13, is attached to the brackets 41,:and vforms a rigid and immovable walk'l about the revoluble platform for the operator. A vrwindlass 42 is mounted on the revoluble platform 13, at opposite sides of the ,tube 20, directly below the booms and each ywindlass is provided with a suitable cable 43, which is passed over the pulley 3 0, on the.ring 27, and over the pulley 37, on the booms, and over the pulley 44, on the hinged forks 45, the end of the cables being fastened to the eye 36, at the'end'of the booms., This rigging'provides means for lowering k.and raising the forks. show manually operable windlass, it is understood that the windlass may be operated by any mechanical motive power, without `departing.. from myinvention.; Ay crank 46, having a shaft 47, connectedther'ewith and While I piercingtheirevoluble platform, and having a pinion 48, secured thereon below the platform, in engagement with the rack 10, provides means for revolving the platform and the vapparatus connected therewith.

A cable 49, is attached to each eye 50, on

'the booms and is passed over one of the pulleys 25, on the cap 23, to the cleats 51, with which they are fastened. This provision is for lowering and raising the booms. A cablek 52, is fastened to the upper end of the hinged fork 45, and passedy over the pulley 25, and through the eye 53, and is dropped along the tube '20. vA weight 54, is attached to` the4 end of the cableto tensio-n the cable.

This provision is for tripping the fork 45,l

to discharge its load. n

The conveyer and stacker, when fully .or-

ganized in the manner described, is conveyed .l

to the material yto be stacked or stored. The

windlass operating the'cable connected with the fork selected to lift the material, .is turned backward', thus permitting the fork to drop toearth, where thevfork is opened and closed upon the material to obtain a load. The windlass is then turned forward, and the cable is re-wound and the fork is lifted to adjacentv the outer portion of the boom. The pinion 48 is then revolved in engagementy with the rack 10, and theplatform andall parts connected therewith, are` revolved. The tube 20, being securedon theplatform 13, is revolved, and it in turn revolves thebooms 35, thereby the loaded fork is ycarried to the point or place selected for stacking the material, within the reach of the booms. When the loaded fork larrives directly over the stack, the' platform 13, is

stopped, and the tripping cable 5.2, is pulled,

cables against the pulleys on the cap 23,

forces the cap and bar 26, connected therewith to turn in the same direction, thereby v the rigging vwill always bear substantially the-same relation tothe operable parts of the apparatus. v

If it is desired to extend the height of the mast, the bar 26, isvraised la distance and held in'place thereafter'by the set-screw39. The forks 45, are assembled inthe manner ofv tongues, vand provided ,with a plurality ofl tines or prongs adapted to pick up and gather hay, straw and similar." and other farm products, the tines or prongs not being 1,30v

shown, a single tine is shown to illustrate the character of the forks.

Having described my invention and explained its mode of operation, what I claim` is- In a eonveyer and stacker, the combination of a turntable, a vertically extending hollow mast mounted at the axis of said turntable, a collar slidably and adjustably mounted on said mast and provided With horizontally extending oppositely disposed pivot arms, oppositely disposed booms pivotally mounted on said pivot arms, said booms having extensible side members having their inner ends straddling said mast provided at its upper end With a rotatably mounted cap having a rigid leg depending i Within the tube, and means connected between said mast and said booms and supportingly engaged by said cap and adapted for rocking the booms on said pivot arms.
