This invention relates. to loaders for' shocks or shefves of grain or like material, "and has for its object to eliminate the use of gears, sprockets, or liketransmission elements ordinarilyemployed for the purpose of rotating; [the elevating cylinder, and to provide whicha tongue 14 is preferably secured. The ,groundwheels are suitably spaced on opposite sides of the inach1ne,and are journaled upon in lieu thereof acontacting wheel-like 'element which when. in ground contact,}will directly rotate the cylinder, and, when lifted, will remain'idle, so that the machine may be readily transported, across the field or on a road, as occasion may require."

Afurther; object of theinvent on is to so co nst-ructtthe supporting" frame for the implement as a whole that the ground contacting element and associated mechanisms may be easily raised and lowered as idesiredloypower lifting means adapted to be actuated hy'the draftof'theimplement.

A further-object of the invention is to pro- "vide nieansifor adjusting or lr'e ulating the claimed.

space intermediate the'th roat of; the gather hag teeth and cylinder teeth, and to provide yicldahle elements at this point' adapted to recedeurscr excessivepressure to prevent choking o'lt'the machine.

A further object of, the invention is to, provide sci) alementalelkevatin ineansyassociated i I b with the elevating cylinder for hft ngthe' material to high level in order to reduce the lee 25th of the inclined transverse conveyor which ultimately deposits the materialonithe accompanying wagon.v

Further objects will appear from adetailed description of'the invention whichconsists in the features of construction and".comloinae shown in Fig. 4.

The forward end of the main frainesupports Theelevated central portion of'the arched axle serves as'an elongated mounting for a drum 21 provided with a pluralit'yrof rowsof teeth or tines 22 which are forwardly curved at'tne'ir outer ends23 and are braced at their atransverse inclined endless conveyor 20 of the usual character.

forwaiwl sidesloy' the' provision ofldiagonally extending brace bars 24 which extend in ohtuse relat on to the ad acent surface of'the. cylinder, so that as the teeth sweep around to discharging position, the shocks: or bundles will not he cramped or crowded into acute angularrelation withrespec t to a. conveyor deck composed of a series ofaendless'belts 25 which surround the drum intermediate the teeth or tines and extend forwardly and. up war'dly to a belt drum 26 suitably supported i'n projxiinate relation to the transverse con veyor'20. The upper turns of the belts co m posing theelevator deck extend upwardly at a slight incline'and. serve to provide amoving surface for strippingthejinaterial from the teethcr tines 22 and carry it upwardly to the point of discharge onto the transverse elevator. The arrangement is one whichele vates the'rnaterial to. a sufficient point to 010-; viate the necessity for providing an excessivelylong transverse elevatororfor providin lateral extensions thereof, as is-customary in implementsofthis character. I v

,The belt drum 26 is mounted upon a transverselyextending shaft 27 which carries the pinion,28-' Whichiniparts rotation to gearing 29. for rotating the transverse conveyor shaft 30, so that'special gear sprocketsorthe like are not required The cylinder 21' serves as a hub for a power wheel 31- connected'tothe cylinder by spokes 32, which power wheel occupies a position ad acent to one end of the a cylinder and is of a diameterto he lifted out of contact'withthe ground when the arched axle is 1noved '1Ilt0 a sulo stant1ally vertical The elevatingcylinder co-operates with a set of gathering teeth 33 which near their upper ends are provided with guide brackets 34 which embrace the transversely extending cross connection 19 and permit the teeth to be moved vertically with respect thereto. Each tooth on its forward or acting face has secured thereto an adjusting tine 35 pro ferably of curved formation, as shown, which tine is fixedly secured at its lower end to the associated tooth and is spring connected at its upper end through the medium of a rearwardly extending adjusting bolt 36 fixed to the tine and slidably entered through the tooth, which bolt carriesan interposed spring 37, and the bolt is adapted to be drawn back by means of a nut 38, so that the normal position of the tine can be adjusted against spring tension to the desired degree. This arrangement provides a spring surface of contact for material so that in case an excessive amount of material. is carried up to the point indicated, the tines will yield sufliciently to prevent choking of the machine.

The gathering teeth near their lower ends are supported by aU-shaped draft frame comprising side arms 39 and a rear cross connection 40, to which cross connection the several teeth are secured by links 41, which arrangement permits the teeth to individually accommodate themselves to ground inequalities which may be encountered. The vertical elevation of the entire series of teeth may be regulated by raising or lowering the draft frame, the arms of which, on opposite sides of the machine, are pivoted at the points 42 to the adjacent side rails of the main frame. In order to provide for the raising and lowering of the draft frame, draw rods 43 are employed, which rods on each side of the machine, extend forwardly and connect with the upper arms of levers 44, which levers are rigidly mounted upon a transversely extending rock shaft 45, so that the parts will operate in unison on both sides of the machine.

and the rear upper ends of the draft frame weight of the draft frame and the gathering teeth. In order to utilize the draft of the machine for the purpose of lifting the rear end thereof to elevate the ground power wheel out of ground engaging position, the following means are provided: One or both of the ground wheels 10 is provided with a brake drum and brake band 51 one end of which is directly secured to the adjacent portion of the arched axle 16, and the other end of which is secured to the bell crank lever 52, the upper end of which is engaged hv a draw rod 53 which in turn connects with a lower end of a lever 54, the upper endof which connects with a forward draw rod 55 which in turn is pivoted to the lower end of a brake hand lever 56 closely adjacent to the hand lever 48, all as indicated in Fig. 3. A notched segment 57 is provided in proximate relation to the hand lever 48, so that the latter may be held in adjusted position.

In operation, the machine, adjusted as in Fig. 1, is drawn to the field and when the point is reached to begin operations, the driver thrusts the hand lever forwardly, which, through the connection shown, draws forward the lower legs of the arched axle into oblique relation with the frame, thereby allowing the rear end of the frame to descend until the ground power wheel comes into ground engagement. Simultaneously through the connection shown, the gathering teeth are lowered into ground engaging posi tion, after which the continuedadvance of the machine will cau'sethe elevating cylinder to rotate and the inclined cross conveyor to travel toward the discharging side of the machine.

As a shock of grain is encountered, the teeth of the elevating cylinder will sweep down over the head of the shock and topple the head backwardly, and at the same time the gathering teeth will pass under the base' of the shock so that the same will be carried up head-first and thereafter it is deposited head-first upon the transverse conveyorwhich in turn will carry it upwardly and laterally in position to be discharged into the wagon which travels alongside the loader without material disarrangement of the sheaves composing the shock. The operation above outlined will continue until completed, after 1O tiallyrvertiCal relation,"thereby affordingthe machinei outof ground engaging position, the
