' Bo it known that I, WARREN WATTS, a eili- I vzen of the United States, residing at Clay Centor, in tho county of Clay and Stato of Kansas, have invented certain. new and usef nl Improvements in Portable Giain.-Elevato1s; and

i I do 'declare the follo'wing to be a full, clear,

and exact description f the inventiomsuch as' will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to thoaccompanyingdrawings, and to the figures of reference marked thoroon', which form a part of this specification.

My invention relates to grain-elevators; and its object is to provide one which is portable to adapt it for use wherever needed, which e may be folded to occupy very little space, and

which, by means of its adjust-able parts, may be` swung from one position to another to suit the requirement of the machine to porfQrm its best work.

My invention is more particularly adapted .to facilitato in delivering the grain from wagons or threshing-machines to a considerin Fig. 1.

able height above them into receptacles, such as granaries, bins, cars,- &c.; and it consists in the c'onstructiomcombination,and arrangement of parts, as will be more fully described hereinafter, and particularly pointed out in 'the claims.

Like numerals of reference indicato corrosponding parts throughout the several views.

In carrying out the invention the essential parts of tho mechanism adaptin g the machine particularly for conveying grain may be arranged in any convenient form of frame.

However, tho preferred embodiment of thoina which extends through the casing at onoend and is provided with asuitablo pulley 9, which may receive a belt to drive a fanning-mill when it is desired to convey the grain from a bin or granary to the tanning-mill. to clean it,v

the construction of which will be described later-on.

vMounted upon tho top of the casing 7 is a hopper 10,'which conducts the grain to the Mounted between screw conveyor and which is provided at the bottom with aslidi'ng valve-door 11, operated by moans of a handle 12. The main elevator -13 connects at its bottom with the screw con` Voyer and extends upwardly to a considerable height above the machine and is p/rovided at its upper ond with a hood 14, ha-vi/ng ah open.

IDO

` vator 15, from which the grain is discharged vto into the granary or bin through the opening 15a at its outer extreme end. This upper section of the top portion of the main elevator may be folded tothe positionshown in dotted lines in Fig. 1 when the machine is not inuse and ready to be transported from'place to place. Each. section is provided with a sprocket at each end, over which an endless which convey the grain.

In Fig.. 1, A representstheend of a wagon, the tailgate being removed, and from which the grain is dumped into a receiving-hopper 16, which is providigd with an upper section 17, one side of .which is almost horizontal, to extend under the wagon-body, as shown at 17a in Fig. 4. rlo Vthe bottom of this receiving-hopper is attached the conveyer 18, which extends upwardly over the hopper. 10, into which it conducts the grain. The grain is then admitted to the screw conveyer 8, when it is caught by the main elevator and conducted to the upper section 15, as before de scribed. The conveyer 18 is swiveled within a suitable frame above the hopper 10 to adapt it to be thrown upon either side of the frame, as shown in dotted lines in Fig. 1, or to the most convenient position for the wagon.

Mounted near the rearward end of the frame .upon the longitudinal sins are the cross-pieces 19, which support a gear-frame 20, the lower end of which provides bearings for the shaft 21, to which the power is atchain revolves, carrying the flights or cups taehed. This gear-frame is rotatably mounted Within a suitable upright bearing 23, secured to the cross-pieees 19. The rotatable gear-frame is provided with a collar 24, keyed upon the vertical portion thereof and provided with a horizontal iiange, through which is formed a series of apertures 23 and in which apertures a pin may be inserted to engage the apertures in the stationary upright bearing to lock the frame in the desired position or in alinemcnt with the driving power. The horizont-a1 driving-shaft 21 has mounted thereon a beveled gear 25, which meshes with a bevel-gear 2U, which imparts motion to the second bevel-gear 26, Mounted upon the cross-pieces 19 are suitable standards 27, which provide bearings for thecounter-shaft 2S and which counter'- shaft has rigidly attached thereto a bevelgear 2t), meshing with the, bevel-gear 26, This counter-shaft carries a sprocket 30 and a belt-pulley 31. The former is connected by a sprocket-chain to the'sprocket 32011 the horizontal shaft journale in the frame of the crane Iand revolver. '"i vertical shaft 33 through theZ bevel-gearsA L ",Qand 33 at the base of the crane. At the ltop of the vertical shaft 33 is mounted a sprocket 3L, which is connected bysprockct-gearing tothe sprocket 35, mounted on a suitable rotatable bearing at the end of the'crane.- On the lowex-,end

of the shaft to which the sprocket 35 is keyed is mounted a bevel-gear 36, meshing with its mate 37v and connected with the sprocket 38 in the elevator-tube 18 lby a sprocket-chain.

`This communicates motion to the endless n ,chain within the elevator-tube 1S, which endrless chain rides over the sprocket39 at the bottom ofthe tube. Y

The pulley 31 upon the counter-shaft 2S is connected by a belt 40 to a pulley 40, mount-ed vided at each end with sprocket-wheels over which the endless chain carrying a series of ght's travels, and this endless chain receives its power from the pulley 40 through a suitable sprocket-gearing 42.

The shaft or screw conveyor has its bearings in suitable hangers 43, depending from the truck-frame, and upon this shaft is mounted a bevel-gear 44, meshing with the bevelgear 45. The shaft of the bevel-gear 45 extends transversely across the gear-frame and has secured thereon a sprocket 46, which connects by a sprocket-chain 4b"t to the sprocketwheel 47 upon the end of the countershaft 28.

It will be seen that the power is applied to the machine through the shaft 21, which imparts motion to the various parts of the machine th rough the intermeshing gears and the counter-shaft 28, the countershatt 28 being provided with a belt-pulleyand two sprocket-v wheels, one sprocket-wheel operating the conveyer 18 through suitable spocketgearing and the othersprockct-wheel 47 operating the screw conveyor through the sprocket 4 6 and bevel-gearing 44 and 45, while the pulley on the counter-shaft connects with the pulley in elevator 15.

to a convenient position above the receivinghopper 1G, as shown in Fig. 1, into which the grain' from the mainI elevator, is likewise prothe main elevator 13 an d the horizontal upper lon a shaft at the top of the main elevator-- IOO IIO

The wagon containing the grain is backed grain is dumped, when it is caught by the' flights of the inclined elevator 18 and con# ducted to the central hopper 10, mountedon one side offset to tit under the' wagon-body, as shown in Fig. 4. The'ba-se of the sliding portion is provided with suitable cleats 47, .which engage tlieedge of the hopper and limititsslidingmovcment. Thedistance the section may be'slid, however, is sutcient to allow the hopperto assumethe correct posi- ,the frame. Thisreceiving-hopperisprovided with an upper sliding section 17, which hasA tion under the wagon-body after the wagon has been backed against the same, and itis guided in iis movement by these cleats 47, which are secured to the onemember and oxtend below'in engagement with tlre sides of the stationary.'portion of the hopper, The

i hinged section may be thrown upward, 'as

shown in Fig. 12. The above arrangement of hopper may beused when it is desired to convey the grain from the bottom of a bin or granary, in which case the horizontal conveyer l is removed from its normal position at the top of the elevator and attached to the receiving.- hopper and connected lwith Vthe Asprocket to the bottom of the same by a suitable chain, as shown in Fig. 1.2.4 i The free end of the upper section is adapted to lie upon the oor or at the lowermost point of the bin, asshown in Fig. 12. The bottom of the hopper is formed of downwardly-convergingsides,

, one of which has fitted therein a sliding valve zo' 49, provided with a handle 50, which extends upwardly beside the conveyor-tube 18 Within convenient-reach of the operator, and when the valve is pushed 'inwardthe supply of grain to the conveyer 18 is cutoff. It will be seen .25

that the'supply of grain can be controlled at will by the regulation of this valve. The base of the receiving-hopper is provided with i a suitable foot 51, upon which it rests.

Mounted upon the truck-frame is a frame 52, supporting a swinging crane 53. This swinging crane is mounted in suitable bearings on the side of the frame 52 and has attached thereto a horizontally-disposed plate 54, lying parallel with the top of the frame.

The plate 54 and the top ot the frame are provided with a series of apertures arranged inthe arc of a circle and are in vertical alinement with each other, so that a' pin may be -inserted within the apertures to hold the crane at any angle desired. By this construction it will be seen that Ithe crane 53 may be thrown entirely around to any convenient position and when thus thrown will be held in the desired position, as the locking-pin is in engagement with the apertures in the plate and the top of the frame. The vcrane is constructed of metallic tubing and comprises a Verticalarm and a horizontal arm. Within shaft 33, to which it secured the bevel-gear 33, which meshes `with the bevel-gear 33 on i the horizontal shaft journaled in the frame 52, lasbefore described. Therotary motion f sprocket'' through the sprocket Stat the .p The horizontal arm'of the crane is provided on its extreme end with'4 l a swivel-bearing 57, through which the shaft y l imparted/[o the shaft 55 through the bevel-l gears at the base of the frame operates the 58,carrying the 'sprocket-wheel 35' and the lbevel-gear 36,revolves,the bevel-gear 36`meshing with its mate 37 and connected lto the l' sprocket in the conveyer 18 and operates the I endless chain in said conveyer 18. It will be seen thatby means of t the swivel-bearing v.57 the conveyer 18 may be thrown around to any desired position or to thev other 4side of ertnre at one end to lit upon the boss ofthe bearing 57 and-at its other end is'formed a longitudinal slot 61,-in which the shaft carrying the sprockets 38 may be slid back and forth to tighten or loosen the conveyor-chain,

as occasion requires. Mounted upon the.

frame 52 is a windlass G2, having the usual crank-handle and pawl-and-ratchet mechanism an upon which may be wound a rope 63, connected with the horizontal upper conveyerl. This rope extends alongside the main cdnveyer 13, passing over a pulley 64., mounted above the main conveyor, and its end is attached to' the horizontal conveyer 15. When the windlass is turned to wind in the rope, the horizontal conveyer is elevated to a position higher or 'above the main elevator or'it may belowered to any desired po-I sition. V y

Mounted upon the truck-frame above the screw conveyer isa circular hopper 10, into which the grain is dumped as itleaves the passes to the screw conveyer. I This 4hopper is provided with a sliding valve 1l, mounted above the opening and controls the supply of grain tothe screw conveyer. The hopper is readily detachable from the frame, yand when it is desired to clean thegrain before it is stored into a granarya cleaning-mill may be attached to the top of the frame in the position that the hopper occupies in the drawings, and as the grain passes from` the conveyer 18 it is deposited within the cleaningmill, which conducts it to the screw oonveyer;V The application of the cleaning-mill will not necessitate the derangeinent of the other parts of the machine other than the hopper. The cleaningmill is usually desired when the upper section 15 is attached to the receivin g-hopper and thev grain is taken from' the floor or bottomof aV bin, as shown inlFig. 412.

'Each olf-the conveyors is formed of two semicircularouter plates 66, overlapping each [other at the ends and secured together by a bolt or rivet, Aa cross-section of the conveyer being shown inFig.

' 7. AThe rivet which.

IIO

holds the sections together also holds apiece of channelsteel 67 withinthe tube andv which channel-pieces act as vguides for the flights of the con veyers. Each flight is formed from a semicircular plate 68, corresponding in shape to one-half of the interior of the tube 66, and eachplate is provided with a flanged portion 69 and a central recess 70. The links ige of the chain are provided with lateral extensions 71, which engage the face of the fiights and aord a means of attaching the same thereto, which may be by means of rivets, as shown in Fig. 7. One end of the link extends within the recessed portion 70, while the other end extends upon the other side of the recessedportion and connects with the the lever 80 willfollow the arc indicated by next adjoining link. By' forming the recesses in the flights the chain is permitted to 'come nearer the center of the load, and a larger sprocket may be used at the heads of the elevators. The form of iiight and the mannerof attaching the same to the chain are shown in Figs. 7, 8,' and 9.

The main-elevator tube 13 is formed of two sections joined together near the middle portion thereof, and when the machine is not in use and it is desired to convey the same from one place to another the top section of the main elevator 13 and the horizontal upper section 15 may be folded down to the position shown in dotted lines in Fig. 1. In order to facilitate and conveniently fold the parts in this position or raise them to the position in full lines, I have devised a novel mechanism, Whichwill be hereinafter described,and shown in Fig. 5. The two sections are hinged to the supporting-arm 74 at a point 75, the supporting-arm resting on the end of the truck-frame and extending upwardly beyond the hinged vpart 75 and provided at its end with an eye 76. Upon the supporting-arm 74 is a blockl 74, having pulleys 77 and 77 therein. These pulleys form the guides for a rope or cable 78, connected to the windlass 79 at the base of the supporting-arm. This windlass is provided with the usual crankarm and ratchet mechanism. The other end of the cable is securely fastened to the end of the lever 80, which is pivoted at 75 to the supporting-arm- 74. The lever is provided with an extension S1, which forms a saddle for the upper section 15 when folded inte the position shown in Fig. 5, and the end of this lever supports a stay-rod 82, which is connected at one end to the end of the lever and at the other end. to the upper section of the conveyer 13. A spring 77b is secured at one end to the opening 76 in the end of the supporting-arm 7i, and its other end is fastened to the upper section of the conveyer 13. This spring aids in raising the elevator as itis released of its tension with the parts when in a raised position. Assuming the parts tobe in the position shown in Fig. 5 and it is desired to raise the elevatol-When the Windlass is revolved, the cud of dotted lines in Fig. 5 until it reaches a point opposite the pulleys 77 and 77, when the pulley 77 will take the cable and the end of the lever will pass tothe position shown 'in dotted lines in Fig. 5, carrying with it its extension or saddle 8l, which will likewise assume theposition shown in dotted lines 1n Fig. 5. Ihe horizontal conveyer 15 may he'raised by the operation of the windlass 62 on the frame hold it within the stirrup. This arm is fitted Within a socket 93 at one en'l of the frame and may be detached therefrom at will. A plan view of the armis shown in Fig. 6.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described machine will he readily apparent without further description,

and it will be understood that various changes in the form, proportion, andconstructien of parts may be resorted to without departing Vfrom the spirit or sacrificing any of the advantages of the invention.
