ELEVATOR CONVEYER.

Application filed March 12, 1920. Serial No. 365,137.

Be it known that l. lncorv'iuni B. Ninetinoirn. a citizen ot the llnited States, and a resident ot' .iloiine, in the county of Rock island and State otlllinois have invented certain new and useful lmprovements in Elevator t onveyers. oi' which the following is a specification. retereme being bad to the act-mnpanyiup drawings.

iily invention relates to elevator conveyers and particularly to a machine of this type for handling: sugar lreets. When beets are har ested and broughtto market they are ordinarily either loaded directly into cars at the rail ay o" are arranged in long piles rt a suitable distance from a track for storage until cars are available. The machine to which this application relates is designed to be used either tor loading the beets into cars directly from the wagon or from piles 'lreviously heaped up as above suggested or for piling; up the beets from the Wagons into large piles when ears are not available. It is the object of my invention to provide in machines of this type new and improved connections between the elevator and its supporting frame for securing improved operation and more convenient transportation and to provide a new and improved term and arrangement. of driving connections between the elevator and the motor by which it is driven. The preferred means by which I have acconuilished these objects and other objects which will be set; forth hereinafter are illustrated in the drawings. That which I desire to cover by this application is set forth in the claims.

In the t'lrawings,-

llet'erring to the several figures of the drawings, it) indicates the longitudinallyextending bars and 11 indicates the trans versely-extending bars of the frame of the. machine having carrying wheels '12 mounted. thereon in any suitable manner. in elevator 12 of any usual construction is pivotally mounted upon the framework as hereina tter described. In the construction shown. the elevator 13 comprises an endless belt 1% of any approved type mounted at the lower end of the elevator upon a shaft 15 by which the elevator is adapted to bedriven for 'arr vin the upper run of the belt l tup ward for carrying beets lOIlQ'ltUllilitlllY of the ele *ator, the endless belt 14- being provided with a plurality of transverse plates it; for rendering the conveyer effective in the manner described.

The elevator 13 is adapted to be swung: upward into inclined position above the wheeled frame by the use of any approved mechanism. The means illustrated cone prises a plurality o? uprights or spars ll' pivotally iounted at the rear end of the wheeled 'l'rame. Connected links 15% attached to the upper end of the uprights and to the forward end of the wheeled t..nue act :15 guys for the uprights ii" to prevent their sw nging; too tar toward the rear. i't tiltiii" comprising" suitable blocks it) and 2 and a cable 21 supports the elevati'ir from the upper end of the uprights. the block 20 being'connected to the upper end port on of the elevator by n'ieans of a system of links indicated by The cable 21 attached at its end to a drum 23 which is rotatablv mounted upon a trame 52 1: rigidlv mounted upon the elevator l3. The drum E2 adapted to be rotated tor \Vll'ltllilfl up the cable 21 thereon by means of a winch which is tixedly connected with a pinion 26 meshing: with a grear 2T fixedly mounted upon the shaft 28 of the drum.

(donning now to the. means tor pivotaily mounting the elevator upon the whee "l frame. ll indicates a rock shaft rotatab mounted in hearings carried loy bars;

llil

10 of the frame (see Fig. The roelrshaft 31 has fixedly mounted thereon two oppositely disposed arms 33 which in the construction shown are formed integrally with the rock shaft. forming therewith a yoke adapted to swing about the axis of the shaft. A heavy shaft 34: extending between the arms 33 pivotally connects the elevator 13 to said arms, as will be understood from an inspection of Figs. 1 and 3. During the operation of raising the elevator 13 into inclined position above the wheeled tame, the elevator rests at its lower portion upon the rock shaft 31 until it reaches the point at which its lower end is brought into contact with the ground. As the elevator is raised abovethatpoint.the lower end of the elevator is shifted along the ground toward the supporting wheels 12 and the elevator is raised out of contact with the rock shaft 31. the arms 33 of the yoke swinging u iward about the axis of the rock shaft 31 idy the provision of a link connection of this sort between the frame and the elevator. affording a movable pivot by which the connection between the frame and the elevator is effected. the elevator is free to rise to the limit of the motion provided by the raising means without the necessity for providing a pit for the lower end of the elevator and without any tendency to raise the supporting wheels at the forward end of the machine off the ground.

The means for driving the endless belt. l4 of the elevator comprises a SPlOtktt gear 35 fixed upon the shaft 15 and a sprocket chain 36 connecting said gear with a sprocket gear 37 fixed upon a shaft 38 positioned on the axis upon which the elevator is pivotally mounted on the arms 33. For this purpose the shaft 38 extends through an axial opening through the shaft 34. as is shown in Fig. Power is applied to the shaft 38 by means of a large gear 39 fixed thereon, such gear in turn being driven by an intermeshing gear or pinion 40 positioned on the axis upon which the arms 33 are pivotally connected with the supporting frame. in order to accommodate this position of the pinion 40, the rock shaft 31 is offset. at this point, in the construction shown the offset portion of the shaft 31 being in the form of a housing indicated by the numeral H. The gear 40 is mounted upon a stub shaft 49 journaled in the end of the rock shaft 31 and driven by means of a sprocket gear 43 fixedly mounted on said shaft. the gear 43 being driven by av sprocket chain it which passes about a.

sprocket gear 45 mounted upon the drive sha ft to of a suitable motor 4-7 mounted upon transversclvextending bars 48 carried by the wheeled frame. For tightening the chain 44, the bearings 32 in which the rock-shaft 31 is mounted are made adjustable upon the bars 10 of the frame. as shown in Fig. 9, adjusting screws 49 of any appropriate type being provided connecting the hearings to the frame for controlling the adjustment and for reinforcing the securing means.

When the machine is prepared for transport-at ion from one point to another, the elevator i2} is, of course, lowered so as to rest. upon the wheeled frame, and the uprights l? are swung downward as shown in Fig. 5. In order to shift. the elevator to a more convenient position upon the wheeled frame than that in which the elevator rests when first lowered out of inclined position, means is provided for swinging the link or yoke comprising the rock shaft 31 and the arms 33 so as to shift the pivotor axis upon which the elevator is mounted whereby the elevator is moved rearwardly with respect to the frame. This shifting means comprises a long arm or lever 50 which by insertion in a suitable socket in the end of the rock shaft 31 is available for eifecting the desired swinging operation. As will be readily understood. this operation of shifting the position of the elevator with respect to the frame comprises successively raising and lowering the elevator as the arms 33 are raised to their upright position and again lowered. The elevator is thus adapted to re main by gravity in either of its adjusted positions. l'tith the elevator in shifted position as shown in Fig. 5. the lower end of the. elevator extends only a. short distance beyond the forward end of the. wheeled frame so not to interfere with the easy attachment of any desired draft means.

By reason of the location of the gear or pinion 40 upon the axis of the link or yoke upon the frame, the arms 33 are adapted to be swung for shifting the position of the elevator on the frame without disarranging the driving mechanism in any way, the gear 39 being adapted to travel about the pinion 40 during this shifting operation without, affecting the operative engagen'ient of the gearing. In like manner, the operation of raising or lowering the elevator above the supporting frame does not affect the driving connections, inasmuch as it involves merely a slight change in the position of the chain36 with respect to the gear 37. In effecting either of these adjustments, the endless belt or conveyor 14 is free to shift may be required to acconnnodate the changed positions of any of the parts.

In the construction shown. the gears 39 and -10, by which the power is applied to the elevator from the power mechanism on the supporting frame. are held rigidly in proper position with respect to each other by the arms 33 which prevent completely any possible tendency of the power to displace the elevator from its normal adjusted position above the. supporting frame. Inasmuch as the engine ll" and the gear or pinion sit) are held in fixed position upon the rigid IOU supporting frame, the lateral pull of the chain 44 upon the pinion 4-0 and its shaft 42 is completely counteracted and there is no tendency by this means to cause a displacement of the elevator.

The construction illustrated in the drawings comprises a conveyer 51 of any approved type for delivering per of the conveyor elevator. Means is provided for driving the conveyer 51 from the motor 47. In the construction shown this driving mechanism comprises a sprocket gear 53 fixed upon one end of the shaft 38 adjacent to the gear 39, and a sprocket chain -t connecting said gear with a sprocket gear 55 mounted upon a shaft 56 journalled in the upper end of the frame 24. The shaft 56 is connected by gearing of any suitable type comprising bevel gears 57, 58, 59 and a with another shaft 61 which is adjustable with respect to the frame 24. The shaft 61 in turn drives the shaft 62 of the conveyer 51 by means of sprocket gears 63 and (34 connected by a sprocket chain 65. The conveyer 51 is connected to the adjustable shaft (31 by means of a detachable connection as shown in Fig. 4: comprising an open slot adapted to receive the shaft which is held in position therein by a cotter 66.
