Application filed December 31. 1906. Serial No. 350.107.

To all whom it ymay concern:

lle it known that l', WILLIAM J. OHM, a citizenoi the 'United States, residing at Minneapolis, in the county of Hennepin and State oi Minnesota, have invented certain new and useful improvements in Loading- Maehines; and l do hereby declare the following to bo a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to rovide a simple and elicientdevice for pic ing up shocks or bundles of grain, winnows or cocks 1 of hay, and the like, and depositing the same in a suitable receptacle such as a wagon driven along by the side of a loading machine.

'lo the above ends, thc invention consists of thc'novel devices and combinations ofdevices hereinafter described and defined in the claims.

ln the accompanying drawings which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 is a view in left side elevation with some arts broken away and soinc parts scctioned,`s rowing 'my improved loadingl machine: Fig. 2 is a plan view of the said machine. Fig. 3 is a detail taken in section on the line w3 x3 of liig. llig. 4 is a detail taken in section on the line '.zf :c4 oi' Fig. 2. Fig. 5 is a detail taken in section on the line so of Fig. 4, F ig. 6 is a transversely vertical section taken lon thel line a of of Fig. 2, sonic parts being left in full; and Fig. 7 is a vliront elevation ofthe loading machine.

The mainframe 1 of the machine is, as shown, a proxiinatcly rectangular, and is supporter at its intermediate portion by a pair oi heavy wheels 2 and at its rear ortion iy a centrally located steering whee 3, the fork Il ci' which is pivotcdt in a bearing 5 on said fra-nie 1, and is provided with a steering lever 6. The` steering lever 6 'is positioned within easy reach of a person Iseated on the, sca t 7 shown as secured to a rearwardly. pro-- jecting bcain 1B of the iraine 1.

Rigidly secured to the intermediate portion of the iraine 1, extending transversely thereot` and spaced apart longitudinally thereof, is a pair of upright frames' 8 and 9. lNorking between the irames 8 and 9 and pivotally connected thereto at its lower 'inner portion isan endless conveycr or elevator,

orting traine made up of an oscillatory sup and an endless slat and l0, rollers 11,-12 belt conveyer 13.

14 secured to the traine 1Q. The said fra-nie 10 is pivotally mounted between theA frames 8 and 9 on the shaft 11 of the 'roller 11, and. hence is free for oscillatory movements in a vertical plane extending transversely ot the machine. To support the projecting iree end of the frame 10 a bail 15 is shown as pivotally attached thereto, and to said bail is attached a hoisting cable 16, which cable, as shown, runs over guide sheaves 17. and 15s. The guide sheave 17 is shown as mounted on the bar 19 that connects the frames l and Q, while the sheave 18'is mounted on the Vfraude beain 1. As shown, the cable 16 is anchored to a securing device 2O on said iraniebeain 11. Projecting forward of the lraine 1 and working freely between the laterally spaced frontend bars of said Atrarne is a supplemental 'frame 21 pivotally connected at its upper end to a part carried by the niain trarne 1. As shown, this pivotal connection is made to the fraine 8 by means of a transverse shaft 22, which shaft at its left hand end carries a sprocket 23k, and within the sides of the suppleiiiontal trarne 21 carries sprockets 2-1. Mounted in suitable bearings in the forwardly projecting lower ends of the said portion of the supplemental portion 2-1 is a shalt 25. This shaft 25 carries large sprockets 264 having rojecting lianges to which toothedpicyk-u 3 27 are bolted or otherwise rigidly secured. rl'he said sprockets and toothed bars constitute what might be designated as a skeleton pickup drinn or cylinder. Sprocket chainswfl run over the alined sprockets 24 and the shafts 22 and 25 respectively. A'lhe transversely extended toothed. bars 29 are attached at their ends to the sprocket elevator.

The forwardly projecting reeend of the supplemental traine 21is supported by a pair of casterwheels 30 pivoted to brackets 31 secured on the sides ot' said frame 21. These caster wheels support the Jr'ree end of the supplemental frame 21 at such elevation that the teeth of the pick-up or cylinder bars 27 will not corne into contact with the round.- To" protect -theteeth of said bars, owever, yfrom irregular or rough surface l projections, a shoe plate 32 isplaced below chains 28, and together therewith constitute; an endless toothed slat and' belt conveyer or The belt 13 runs over the rollers 11e-12, and, as shown, over the deck thetoothed cylinder made up of the sprockets 26and bars 27. This shoe plate, as shown, is secured to thesides ofthe su plemental frame 21 by a yoke 33, which yo e is yieldingl`y""connected to, theframe 1 by a spring thrust bar 34. A The upper portions of the chain .2S-run over an inclined'deck 35, which, at its u per end-is provided with hinged straps pivotally mounted on the shaft 22.V The lower end of this deck is hinged to a pair of brackets 37 .(see Figs. 1 and 4), which brackets are adjustably mounted on the sides of the su plemental frame 21 and are adapted 15 to be eld where set, as shown, by nutted bolts 38 and adjusting screws 39. Jour'- Y naled to each .of the brackets 37 is an idle s rocket which-serves as a tightener for the ained elevator chain 28. It will thus *be seen' that adjustment of the brackets 37""'simultaneously adjuststhe chain tightening sprockets 40 and the lower edge of the deck 35.-

l'Ihemachine described is capable of being vdriven in diiferent ways, but as illustrated in the drawings, it is intended tobe pushed for- Y ward by ap pair of horses, while the conveyors or elevatprs are positively driven by-an engine carried by the' truck ofthe machine. This engine, which may be assumed to be an explosive engine, is indicated as an entirety by the lnumeral 41, and is shown as mounted 'on the. rear portion of the frame 1.. The

crank shaft 41al end. with a beveled pinion provided at one 42, and at its other end with a s rocket 43. 'The beveled pinion 42.meshes Wit a beveled gear 44 on the roller s'haft 11a and hence imparte motion to the elevator o r conveyer 40 12-13. A sprocket chain 45 runs over the sprocket 43 and ,over shaft 22, and thus transmits motion from the engine to the elevatoror conveyer 28-29, and of course also to the toothed pick-up cylinder or drum.

The pivotal or yielding action between the mainframe 1 and supplemental frame 21 permits all ofthe wheels 2, 3 and-30 to keep contact with the ground in running over irregular or rough surfaces. Primarily this device is intended for use as a, shock loader for picking up bundles placed in loose shocks and elevate the same into a wagon driven along by the side of the machine Under" the forward movement of the machine, when the toothed bars 27 `of the pickup cylinder come into contact with-bundles .of grain, either loose or in shocks, they will lpick up and carry the same upward where they will be taken hold of by the toothed'bars 29 and carried on u ward over the deck 35 and deposited on t 1e-receiving end of the transversely extended elevator or conveyor 12-13. .As shown in Figs. 2 and 6, a dedoctor plate 46 securedA to and lbetween .the

of said engine is shown asv the sprocket 23 of they -in presence of stesse upright frames 8 and 9 assistsin deliverin the bundles onto said -transversely extende elevator. The bundles delivered to the said. transversely extended elevator 12-13 will be carried up thereby and to one side of the machine, and will be dro pedor discharged into the box of a wagon w `ch may be driven along beside'the machine.

As already indicated, the device may be used for picking up hay or other materials from the ground, and loading the same into n wagons. The loading device is Well adapted for use in picking up loose i'ax and depositlng the. same in a wagon.
