'Be itnknown' that I, Cn sTER BRAD ORD, a citizen o f'the United States, residing at Indiana olis, in the county of Marion and State of 'ana, have im ented certain new and useful ln rov'ements in Swinging-Conveyers, offwhich the following is a s )ecifioation. In the class of dev ces w ich are attached to'threshing machines to receive the threshed 'grain'from these arator, elevate and weigh thesame, and de i'ver it to stacks or wagons for ther disposition, two distinct varieties of the grain' delivering: or transferring device '-';,con'1.m onl known as a Fcross conveyer are is employe .Oneis the well irnown stationv ary?icross conveyor which is mounted upon the deck of the separator-and remains con: tinuously'in the position where placed. The; other is supported ,by pivotal mountings and; is ada ted to swing. to Various positions,. so that t e grain can be delivered at different (points by merely moi-ing the discharging end of the eonireyer to t-hepoint desired.

describedlfor the purpose of pro'vidingroom "vention', and therefore will not. be described herein exceptincidentallyin describingmhe The c'onveyer proper has the usual aiiger shaft 21 and worm or auger .22, said shaft .being mounted, in sui-tablebea rings in the ends or heads of the tube or casin -23 which forms the principal part of"th e shell of the convey-er. Said conveyer is provided at its discharging end with a discharging mouth i 24; and its opposite end develops into 'a mi ceivmg mouth having an end inclined walk 25, and to the uppenedg'e of this mouth (whichic onstitutes the lower part of the receiving hopper) the'upper portion 26 of said, hopper is scured'this portion being located .directlybelow the weigher W, or thedischarging ,ii outh of the elevator, (according to the? variety of 1- nachine with which the coni'ey'er is used) and is adapted to receive the grain. I The wall 25 is inclined (as shown and just forthe peculiar arrangement of driving gears which have devised. It also faclhtates the flow of thefgrain to the auger, and en ables't-he eonveyer toclean itself more thoroughly in operation." To the outer and under side 'of this inclined'wall is secured a bearing .31 .for the {shaft 21. In the same structure'is also a socket to receive the pivot shaft 32. Said ivot shaft is lprox ided on its lower end wit a bearing-plate 3.3 which rests in asiiitablecavity in the hracke-tmemhers 3 t. The bearing surface on the part- 33 is preferably of the form ofa zone on a lobe,

the center of which is coincident with the center of'the gear trav eli on the ivot shaft, as will bepres'ently. descrl ed,'am the corresponding surface onthe part- ?A is similarly formed. I This permitso the slight o'scillation desirable to a support of this cheraoter, without causing an of the parts,to;' 'bind.

The supporting bracket is 1 shojiinfas'fforn ed in two pa- rts 34 and 35, the' par't 35" be i i1g., fitted toone leg'of the elevator E and being Y clam ed thereon by clamping.Qbandsjfifi. The rackethowei'er .nii ht be madam 5 singl iepe dfisir l the" ead arts are assemble secured to they}: (1

. a shown 'in the' form'fof a s'litted pla enga es with the upper side of a corresponding d ouble bevel gear 42 which is mounted loosely on the pivot shaft 32. The under side of said doublebevel gear 42 engages with a bevel gear 43 which is mounted on the driving shaft 44, said driving shaft being mounted in suitable bearings secured to able bearings in a bracket 51 which is ad 'justably mounted on the other leg of the elevator from that on which the bracket 34-35 is mounted and is secured thereto bysuitable clamping rings (or rather half-rings) I 52. Said bracket is adjustable on said vator leg both circumferentially and longitudinally, and is thus capable of being admated to [the exact position desired. The

, earings 53 for said countershaft 45 are also adjustably mounted in the bracket, being supported upon one side by projecting oints 54" which enter suitable cavit1esin t e ad'- 'acent sides of Tsaidbearings, so that said earings' are capable of shding' somewhat thereon, and upon the other side by means of set-screws 55, the points of which enter cavitiesin the opposite side of said bearing.

Said set-screws are also provided with jam" nuts 56 by means of which they'may be securely locked in adjustable position, Said "bearings'are thus rendered self-adjustable,

so that. they will line u properly with the shaft automatically. he countershaft is. shown as alsodriving the main upper elevator shaft 61 by means of a s rocket chain 62 running over suitable sproc et'wheels' 63' a belt 65 and 64,. and as being driven 'bIy e separator from somesuitable pulley on t (notshown).

The bracket'34+35, like the bracket 51,

'is-adgustable on the elevator. leg both circum erentially and longitudinally, and the conveyor may thus. bebrought to the exact position desired. The outer portion of. the 1clongeperis sup f'orted. froml the elevator y "a suita'le and preferably flexible 'su ort 71 running from a pointsubstam (where it is shown as connects to said headby ja'bracket 72) over the end of a strut 73 to a bandsurrounding the tube .or casing 23! or weigher'fa down theinclined wall 25 follows: e figain comingfrom the elevator into the hopper 26 and slides through which, the auger-22 conveys it rap idly to the discharging per-is circular. in are: so that it're'ceives y perpendicular above the pivot shaft 32 into the tube 23 month 24. The 'hkolp;

grain with equal facility at whatever position the conveyor may be placed.the center of said ho per being substantially perpendicularly be ow the center of the weigher bucket, asshown. The an or shaft 21 is driven in any positionby t e gears which have been described from .any suitable source of power-usually the countershaft 45. By

reason of the peculiar form of the conveyor end these gears are enabled to be of substan tial size and pro ortions and to be located centrally below t e hopper and receiving end of the conveyer. As will be obvious, "the gears perr'nit the swingin of the conveyor to any position desired, eit er across the separator, or extending out therefrom, and to be so positioned as to be able to deliver into a sired.
