ELEVATOR.
To all whom/ it may concern:
Be it known that I, CARL A. LAnsoN, a citizen of the United States, and a resident of Stromsburg, in the county of Polk and State of Nebraska, have invented anew and Improved Elevator, of which the following veyer and having its sole connection through the medium of said conveyer withthe over- With the conveyer forming the connection between the bottom structure and the overhead suspending structure, the use of an elevator well,
'7 rigid guides, and the like, common to elevators in general, is dispensed with- The elevating con'veyer is of a character to permit it to be lengthened or shortened, and to thls end use is made of an endless conveyer chain having buckets; The conveyer chain lends its'elf'to the extensible feature, in that, at
' open links of any approved form, lengths of 'chainmay-be added or removed so that the elevator will extend to the desired depth andmay be readily lengthened as the material is removed from the silo, or the excavation' increases in depth. The structure sup- Figure 1 is a perspective view of aneleported by the conveyer chain at the lower end of the conveyer, includes an elevator boot having a hopper and chain wheels over "which the elevator chains run. In addition,
the said structure supported at the lower end of the conveyer, carrieselements adapted to'bear against the sidewall of a silo or excavation to steady the structure. Also I employ elements to engage the chain "con- 'veyer and extend upwardly from the eleivator boot to assist insteadying the structure. I
-- The invention willjbe particularly described in the specific; description following.
' "Reference is had to the accompanying drawings forming part of this specification,
' in which similar characters of reference indicate corresponding parts in all the views, and in which:
vator embodying my invention, showing the same applied to a silo; Fig. 2 is a'sectional I Specification of'Letters Patent. Patented NOV, 2., 1915; j Application filed January 25, 1915. Serial no. L H- side elevation showing the elevator applied to asilo of somewhat different form from that in Fig. 1; Fig. 3-is a detail transverse vertical section showing the lower portion of the elevator chain and the structure-supported on the chain at the lower end thereof; Fig. llS'iL horizontal section onthe line Fig 3; Fig. 5 is a horizontal section approxlmately on the line 5-'5 Fig. 3; Fig.

structure is provided, which may consist of posts 1 0 resting on a platform 10, or other support. The posts 10 in the example shown support a hood. 11 having a chute 12 to di scharge the elevated material.- In Fig. 1 1s indicated a silo A,.of' one form, andin Fig. 2 a ilo A of slightly different form. The chute 12 is supported above'the platform10 to discharge material to a wagon.
. 80. In Fig. 2 the hoodll is above the roof a of a silo, so 'thatmaterial inay'be brought upward through an opening a in said roof.
In the-hood 11 a door 13 may be provided r for affording access to the interior. I
An elevating conveyor is provided pref erably in the form .of endless chains-14 having buckets15. The chains are, freely suspended from the overhead structure, there being chain wheels 16 over which the said chalns run, and 111' pract1ce,., 1dler chaln wheels 17. The idler wheels 17' servethe important function of guiding the chains 14, and directing the dumped buckets 15' ,iinwardly,'to5clear the upper edge of the" chute 12, in the downward run of the chains.
Supported on the conveyer chains 14: at the lower end is a' structure designated gen- .erallyby the numeral 18,'which comprises an elevator boot 19 and shaft 20 mounting chain .wheels 21' about which the chains 14: run. At the upper end ,of theelevatorboot Drivemeans are provided for the chains '14. In. the illustrated example I have shown drive' means for the lower end of the chains to be manually -o'1; erate.d,-- and powermeans'for the upper end of the chains, to be employed optionally. The illustrated drive means for the'lower end of the elevator "chains 14: consists of a is a hopper 22 into which the material "maybeshoveled 1 V j sprocket wheel 23 on the shaft 20 and a chain belt 24 which runs over said wheel 23 and over a sprocket pinion 25 on a countor-shaft 26, the latter shaft having a crank handle 26. The power drive means for the upper end of the elevator, as illustrated, comprises a sprocket wheel 28 on the shaft 27 of the upper chain wheel 16, said shaft havingsuitable bearings on side bars 29 on the hood 11, there being additional side bars 30 having bearings for the shaft 31 of the idler wheel 17. A chain belt 32 runs over the sprocket wheel 28 and over a sprocket pinion 33 on a shaft 34, the latter having a pulley 35 to be driven by a belt from any suitable source of power (notshown).
It will be seen that the structure 18 and the elements appurtenant thereto are sustained on the elevator chains 14, the latter being the sole medium of connection between'the said lower structure and the overhead suspending structure. The chains may have, at one or more points, removable pivots or pintles 14 whereby to insert or remove lengths of chains to lengthen or shorten the elevator as the material in the silo or excavation is removed. In adjusting the length of'th'e conveyer, it will be seen that only the lower structure 18. needs to be manipulated, and that the same is comparatively light. By the described construction,
therefore, anelevator of any desired length may be provided to suit the conditions, and the portability and general flexibility of the structure is greatly superior to elevators having distinct Wells and rigid guides connecting the lower structure, including the elevator boot with. the overheadstructure. In order to steady the lower structure 18, the latter may have shoes 36 at a side thereof pivotally mounted on across bar 37 which is carried on arms 37 suitably pivoted at opposite ends to the structure 18. Chains 38, secured to the cross bar 37, may
be engaged over hooks 38 (Fig. 3) whereby to sustain the arms 37" and the shoes 36 laterally disposed, so that the said shoes may bear against the side wall of a silo A or A or the side of an excavation.
, To facilitate the assemblage of the hopper 19, the latter is formed intwo side sections' having an approximately centraljoint, as best seen in Fig. 7, one section. having a strip or flange 39 secured by bolts 40 to the adjacent section. The inner wall 19 of the boot 19 is spaced from the outer wall suffijciently to provide a curved way for the buckets 15.
The back 41 of the elevator boot may be adapted to he slid vertically, and desirably has a returned flange 42 at its upper edge to engage the back wall of the hopper 22. The central portion 43 of the bottom or back of the hopper may be separate from the. sides 44, and be secured to the'latter by bolts 45 (Fig. 1). A transverse bolt 46 ties the opposite sides of the hopper at the rear.
In order to further provide a steadying means for the suspended lower structure 18, I provide the hopper with upwardly extending channels 47 spaced to engage the opposite chains 14 of one run of the said chains, preferably the downward run or stretch. The channels 47 open at the inner side toward ach other to snugly. engage the said chains while permitting freedom of movement to the buckets 15 carried by the chains. 1
In the use of the elevator after the latter hasbeen placed in position in a silo, or in an excavation, the material is shoveled into the hopper 22 and the elevator chains are driven through the medium of the shaft crank 26 or the power shaft 34. As fast as the material is removed from the bottom of the silo or excavation, the chains 14 are lengthened to lower the structure 18 to suit the new level. A material advantage attending the use of my improved construction is that when the elevator is used in a silo, the elevator may be conveniently dismembered and stored in compact form after the silo has been 7 emptied. In addition, there is economy in doing away with the rigid well and guide structure extending usually from the boot of an elevator to the top.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
1. In an elevator, elevating conveyer means, overhead means freely suspending said conveyer means to permit the same to hang in a. silo or excavation, a structure supported on the said conveyer means at the lower end of the latter and having its sole connection with the overhead suspending means through the medium of the said conveyer means, a vertical rocking frame on the 7 said structure extending at a side thereof,
ing said conveyer to permit it to hang in a silo or excavation, an elevator boot supported on the chain conveyer at its lower end and suspended with the latter by the said suspending means, and a hopper in rigid relation to the elevator boot, the back of thehopper being within the plane, of one run of thechain, the adjacent side of the boot being outside of the said back and cut off from the hopper, the front of the hopper extending outwardly beyond the adjacent side of the boot and in communication with said boot.
3. In an elevator, an endless elevating conveyer,means freely suspending said conveyer to permit it to hang in a silo or excavation, an elevator boot supported on and by the said conveyer at its lower end, and formed with a curved way for the conveyer, the said way being closed except at-its ends, and having top and bottom Walls, and a hopper sustained on the said boot, above the said top Wall, the hopper having the back thereof within the path of the adjacent run of the conveyer and inside the adjacent end of the said curved Way, the front of the hopper projecting beyond the adjacent end of the :said curved Way and in communication therewith for the passage of the con veyer therethroligh.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. I
