UNETED STATES ALFRED F. MEYER, OF MORTON, ILLINOIS,

' MORTON, ILLINOIS, A CORPORATION OF ILLINOIS;

PATENT OFFICE.

ASSIGNOR TO MORTON CORPORATION, OF

ELEVATOR.

To all whom it may concern.

Be it, known that I, citizen of the United States, residing at Morton, in. the county of 'Lazewell and State of Illinois, have invented, certain new and useful Improvements in Elevators, and do herebydeclare that clear, and: exact description of the invention, which will enable others skilled in: the art to which it appertains to make and use the same.

'This invention: relates to. improvements 1 elevators, particularly that class used in granaries andilike- .placeswhere grain, especially ear corn, is to be conveyed fromonere cept acle to another.

It still further relates to improvements in elevator ofthe permanently located so called vertical type used for elevating grain.

The main object of; the invention is: tov

construct an elevator and boot wherein the elevating chain is guided through, a runway upon an abutment in such boot, in lieu'of the usual sprocket wheel; or wheels so that/the entire space in the bootwill bedevoidof obstructions such as usually interfere with the handling of materials,

especially ear corn. Another object is to provlde, a; structure which the elevating chain does not require the sprocket wheels and their supporting-shafts ordinarily used in sald; boot so thattheelevating buckets therefor carrying the ear corn can travel freely with; no dangerof damaging them or of breaking the chain or straining any of the portions ofwthe elevator structure with the added advantage of requiring less power for the elevating operation.

Another object is to furnish an elevator boot structure in which, together with the fact that; said'bootis free and open for substantially its entire area at one-side forreceiving the ear corn, a larger bulk of the latter can be accommodated resulting in a saving of time required in elevatinga given quantity thereof.

Still another object is to provide an elevator structure wherein the elevating chain in'its boot is adapted tooperate the-usual drag chain of the conveyer 'thatsupplied grain to such boot. V

ther objects and advantageswill appear as the description proceeds, the invention-relating alsoto certain details ofoonstruction Specification of Letters Patent.

and arrangement of parts to be pointed. out

herein and form the subject of certain of theclaims.

In order that the invention may be, clearly understood, I have provided, the accompanymg drawings showing a preferred manner of constructing the elevator and its boot, though it s to be understood that changes may be made such as will stilllie within the meaning and intent of the invention and the scope; of the claims.

F lgure 1 is an elevation of a granary showing my improved elevating structure;

therein. 7

Fig. 2 is a sectional elevation of a part of the, leg; of the elevator.

F ig. 2 shows, in perspective, certain cletails of construction of the elevator boot.

Fig.v 3. shows, in perspective, portions of the structure illustrated in Fig. 2.

Fig 4 is a sectional elevation of the ele-- vator'boot.

, Fig. 4 is a detail of a portion of the elevating chain.

Fig. 4? is a detail, in perspective, of a portion of one of the sides of the elevator boot; and,

Fig. 5 is a horizontal section of theele vatorboot ShOWlIlg a loading conveyer I associated therewith.

A indicates, as a whole, the leg of the'elevator, and-B=the boot thereof. For convenience in constructingthe latter portion two parallel side members C are employed, which may be castings, each of which includes an outwardly extending annularup: of pairs of ers H.

J indicates a sheet iron member stationed between'the spaced members C, there being a flangeK onthe inner face of each of the latter, for example, to receive the member J against it, bolts L serving to clamp the sides and said. member together to form a rigid structure.

The said side members C are each provided with an outwardly extending flange portion M, Fig. 4 forming a support for timbers N, N, O spaced from one another as clearly shown in Fig. 4, providing guideways P communicating with the said chan- Patented Nov. 1, 1921-.

nels E, the sheet'iron member J extending up upon the outer surface of said timbers to said sleeve.

- At one end of-the through the long curved N to complete the leg.

One of the members boot at one side as Q, the opposite member is very large receiving opening R grain.

S indicates the usual conveyer or drag, and T is a chute to receive the grain therefrom and conduct it into the boot.

U, Figs. 1 and 5',indicates a stud extending from one of the side members 0 to support the conveyer and upon which said conveyer may swing vertically, although it is to be understood that other means of supporting7said conveyer may be prov ded.

Fig. 4, is a sprocket wheel secured upon a sleeve W rotatably mounted upon the stud, which structure is well understood, the usual sprockets 2 of the conveyer being secured 3 indicates the drag chains for the conveyer and 4 the flights secured thereto. 5' is a shaft mounted in suitable bearings 6 secured to the sides of said boot. said shaft is secured a sprocket wheel '7 overwhich is trained a sprocket chain S also trained over the mentioned sprocket V of the conveyer.

The opposite end of the shaft 5 is furnished with a sprocket wheel 9 which at one edge projects through a 5, in the boot and leg structure into one of the channels E and in the path of travel of the chain F, H which is provided with the usual elevating buckets 11 which have been shown in broken lines in the figures.

The right hand stretch of the chain as viewed in Fig. 4: travels downward to work into and pick up the grain and as the sprocket wheel 9 engages this portion of the chain it is rotated contrary clockwise as viewed'in said Fig. 4, with the result that the flights 1 of the conveyer or drag will travelin the proper direction to discharge the material into the chute T, the chain F, H being driven by any suitable power attached at any point. 7 I

The diameter of the boot structure is much greater than the width of' the leg A in ord'er'that, first, the chain in traveling track furnished by C entirely closes the Figs. 4: and 5, while furnished with a the channels E may have disposing the links so as to have as nearly a straight pull as possible, and, second, in order to'provide a very large receivingspace for the grain. The leg A can be made com paratively small in compass soas to reduce its cost and the space required for it.

-frnotheradvantage in making the boot much greater in diameter than the measuremer t of the leg A is thatthe ascending chain portion is bent inwardly as it moves along the abutments which create the channels E and thus any ears that are in excess of those for the,

free movement by required to completely fill the buckets will 7 slide off into the boot due to the inclination of said buckets but should any of them be still retainedtheir disposal will be as explained later.

The leg is slightly wider than the space required for the buckets 11 as they pass one another, and, as shown in Fig. 2, a dividing member 12 is employed which lies nearest the descending line of buckets, thus giving greater space to the ascending line. 7

The purpose of this peculiar disposal of the dividing member is that when the chain is ascending at an angle such as shown in Figs. 1 and 2 any ears that fall from the buckets will have room to pass between the buckets and the member 12 without becoming wedge and the latter will guide the ears back into the boot or into one of the ascending buckets lower down, said member serving as a chute for the purpose:

In Figs. 1, 2 and 3 I have shown a structure which rovides for slight changes in the angle of the upper portion ofthe elevator leg as occasion may require.

There is provided a pair oficastings 13, but one of which is shown, each having a face to lie flush with the inner surfaces of the timbers N, N, 0, there being hannels 13- for the chains, there also being flange por 95 tions 14 to receive the said timbers. These l flange portions have extended cheek-portions 15 which are received into the timbers by slightly recessing the latter as shown at 16.

his casting may be used different angles at which it may be desired to place the timbers of the upper end of the leg. This may be accomplished by simply changing the angle at which the timbers may be cut at their lower ends where they rest upon the casting; The differences in inclination of the timbers has been indicated by the two series ofdotted lines in Fig. 3.

The described member 12 of Fig. 2 is preferably ofsheet iron and is secured to a flange 17 on each of the described castings 13 and to strips 18 on the timbers.

It is clear that any slight changes in the angle of the upperportion of the leg will not effect the free running of the elevating chain since the channels 13 provided in the castings willsmoothly guide the rollers H.

In boot structures it has been customary to provide certain internal structures to prevent the ear corn catching upon the sprocket wheels, shafts or other parts of the structure for preventing breakage of the chain, or parts as stated earlier herein. This makes for complications and even then thedanger to the parts is'not entirely eliminated'and in 12: view of this the herein described structure is provided whereby there are no parts in the way of the buckets 11 but,instead,there is an entirely, clearspace for the reception of the material to be elevated and for the 13 for a number of 100 V for a free travel of the buckets which, even after passing into the leg, are in no danger of being caught by any part nor is there danger of wedging of the ears between the buckets and otherparts.

he elimination of the usual sprocket or other wheels in the boot for the purpose of carrying the chain necessitates the channels E in my structure and in order to provide chain the rollers H are provided. While the use of rollers upon a chain is old it is believed to be new to employ a chain Within a s'tantially as shown and. described, the rollers being naturally used to reduce the friction. aving thus described my invention, I claim 1.
