Gaiam Appucauon iediuiy 7,

To'aZZ whom) #may concern? Be it known that'I, ESEB'E' CRAITE, a citi#v zen ofthe United: States, and a lresident of Rice Lake', in the county ofi Barron and State of lVis'c'onsin, have invented anew and Improved Grain Sacher, ofy which the fol# lowing is a full, clear,andexact description.

This invention has relationv to an'apparalJ tus for handling granular materials, and has particular referenceto 'a' portable device for. sa'clring grain. A In sacking" grain, is" theV common practicev at'the presenttim'e to employtwo nnen,l one for` holdingthe sackl and'oneA for shoveling the grain'.v The' present invention contemplates as an obJec't, anv apparatus operable by one man which will expeditiously scoop vup and sack the grain, thereby elimi-` natingjthev eXtra man and effectingV economy of both timel and labor.

As a'further object'the invention contemplates' an apparatus" of the character' set forth, which is extremely,l simple" and` ineX'- pens'ive to manufacture, which isstrongand durable in its' construction, and' which ishighly efficient in itspurpos'e.

With the abovef recited andV other objects in View, the' invention residesin the novel construction, combination and` arrangement ofp'arts'set forth in the following specification, particularly pointed out'in the appends ed claims andV illustrated in the accompanyingfdrawings, it beingrunderstood that variationsand mo'diiicationswhioh properly fall within the scope'of the appended-claims may be' resorted to when foundv` desirable.

In the drawings#- Figure 1 is a longitudinal sectional view' through' a grain sacking` apparatus const'riict'ed in accordance with the invention; Figure'2 is a' fragmentary side elevation thereof; Y

Figure 3 is a front vie-W'of the same; andl Figure 4 is a top plan veiw thereof. Referring-to the drawings by characters of reference, the` apparatus embodies a platform 10, which is supported adjacent one end by caster rollers 11, while the opposite end is designed to rest upon the floor. An upstanding rearwardly inclined elevator housing 12 is provided at the forward edge of the platform and is formed at its upper end with a rearwardly and downwardly curved discharge chute 13, which is disposed in vertical alignment with the rear portion of the platform 10. An elevator 14 is ar- Saonara.

ranged within the elevator housing 12anid consisten-f an endless heiter Chain 15";whieh is trainedl over',l a lowerv driven p'ulle'y'v ,16`

andan upper drive pulley 17., JLe;plurality;

of cups or bucketslS are attached to' the belt' or chain 15 for scoopingfup and'elevatingjthe grain which is'suppliedto the lower end4 ofl the elevator housingl 1.2,: said buckets or cups being designed to discharge" their contents' into' the' discharge'chute" 13,F during their passagearoundj the upperdrivepulley 17. TheA forward" lower.' @ad @jf the elevator housing 12 is open and has projecting'. for? 'Y wardly therefrom a scoop 19,' thefforw'arld edgeof which closely contacts' and engages'- With theY floor. Thel oppositesides 270E of the? scoop' are of substantially semi-circular-for mation and said scoop islof subfstantiallyy greater width than the width' ofthe elevator" housing 12. 4' A" pairl of spiral conveyorsu 21l arev disposed longitudinally of the scoop in transversely spaced relation', saidconveyors being partially embraced by theo semi-circular side walls 20,.:V The conveyors 21 are" mounted on parallel longitudinally sh`aft's`22are4 n'iourixdin bearingsf25 on they platform 10 and havev keyedl thereto beveled drive pinions 26, which mesh with' beveled gears 27 securedA tothe transverse shaft/Z 2481" which extends through the'V elevator housing;4 '12 and as niounedthereonthe driven pulley' 16' ofthe elevatorlef The gears`27 which drive the'pinions 26 are reversely'arranged" on thesh'aft 2 8, whereby the spiral' conveyors'21 areoppositely driven' to'feect the scoopingand feeding ofthe vgraintoward the center of'the`scoop19 andfin'to the;l lower'k end of the elevator housing`112.A The reai end of lthe scoop 19 is. slightly @elevated with respect toV the forward lend' of the platform" 10 and the frontendoftheplatforniis pro-y vided with an upturned extremity or an upstanding wall 29.- The upper drive pulley 17 .is mounted on a transverse shaft 30 which extends preferably through the right hand wall of the elevator housing 12 and ,has keyed thereto a pinion 31 arranged exteriorly of the elevator housing. A drive gear 32 having an operating crank 33 is journaled on the side of the elevator housing 12 andA meshes with the pinion 31 to adord means for manually actuating the elevator 14 and the spiral conveyors 21.

In use and operation of the sacker, a sack A is clamped over the lower end of the discharge chute 13 by means of a clamping ring 34 which cooperates with the exterior' annular bead S5 on the lower end of the chute. The lower end of the sack A is designed to rest upon the rear portion of the platform 10. The operator advances the scoop 19 into a heap of grain or a bin and turns the crank 33 and the drive gear 32 in the direction indicated by the arrow in Figure 2, thus turning the pinion 31, the shaft 30, the drive pulley 17, the endless belt or chain 15 and the driven pulley 16V in the directions indicated by the arrows in Figures 1 and 2. Simultaneously the shaft 2S, the gears and pinions 27 and 26, the shafts 22 and the spiral conveyors 21 will be turned in the directions indicated by the arrows to feed the grain through the scoop 19 into the lower endof the elevator housing 12 where the buckets or cups 18 will scoop up the same, elevate the contents thereof and discharge said contents through the discharge chute 13 into the mouth of the sack A. l/Vhen the sack is filled, the clamping'band 3a is removed and a new sack is applied over the end of the discharge chute 13. The sacker maybe moved aboutl on the caster rollers 11 with the forward end resting on the floor.

I claim: y

1. A portable apparatus for scooping up, sacking and moving the sacked grain comprising a platform, supporting casters for said platform intermediate its ends, an elevator housing adjacent the forward end, a scoop projecting from and communicating with the lower end of the elevator housing, means within the scoop for moving ther grain therethrough into the lower end of the housing, means within the housing for elevating the grain, a rearwardly disposed downturned discharge chute overlying the rear portion of the platform and with which a grain sack is adapted to communicate, said sack resting upon the rear of the platform, whereby upon forcing of the scoop into a pile of grain and actuation of the device the weight of the grain within the filled sack serves to counterbalance the weight of the elevator, housing, scoop and the grain and elevating means to facilitate the movement of the device and transportation of the sacked grain.

2. A portable apparatus for scooping up and sacking grain comprising a platform mounted on supporting casters for longitudinal rocking movement, an upstanding rearwardly inclined housing at the forward end of the platform, an endless upstanding elevator in said housing, a rearwardly disposed down .turned discharge chute at the upper end of the housing overlying the rear portion of the platform and adapted to receive thereover the mouth of the sack which rests upon the rear of the platform, a scoop having communication with the lower end of the elevator and projecting forwardly from the platform whereby upon forward tilting the front end of the scoop will engage with the iioor, a pair of longitudinally disposed spiral conveyors in opposite sides of the scoop, and means projecting laterally from the side of the housing for simultaneously actuating the elevator and spiral conveyors, whereby upon thrusting Vof the forward end of the scoop.

into a pile of grain and actuation of the elevator and spiral conveyors the grain will be scooped up and dischargedfinto the sack.

3. An apparatus for scooping up and sacking grain, comprising a platform mounted on supporting caster rollers for longitudinal swinging movement, an upstanding rearwardly inclined elevator housing on the portion of the platform in front of the caster rollers, an endless elevator in said housing, a rearwardly and downwardly disposed discharge chute at the upper end of the housing adapted to receive thereover the mouth ofa sack resting upon the rear platform, a scoop projecting forwardly from the lower end of the housing in a plane above the bottom of the housing and having communication therewith, a pair of longitudinally disposed spiral conveyors at opposite sidesof said scoop for feeding the grain through the scoop and into the lower end of the elevator housing when the forward end of the scoop is forced into a pile of grain, and a common means for1 actuating the elevator and for driving the spiral conveyors simultaneously to scoop up, elevate and discharge the grain into the sack whereby the weight of the grain when the sack is filled serves to counterbalance the weight of the elevator, housing, scoop and conveyors to facilitate the movement of the device.
