Patented Jan. 16, 1906.
To all whom it may concern.-
Be it known that we, GUsTAvE WENZEL- MANN and EDWARD H. OVERHOLT, citizens of the United States, and residents of Streator, in the county of Lasalle and State of Illinois, have invented certain new and useful Improvements in Portable Grain Elevators and Conveyers; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
This invention relates to improvements in portable corn and grain elevators and conveyers adapted to be conveniently movedv from place to place to facilitate the unloading of grain, corn, or the like into cribs or granaries. Heretofore most of the devices of the kind have been unnecessarily heavy and complicated and are neither so made as to enable the parts to be quickly arranged for moving nor provided with suitable means to enable the move to be made with small expenditure of power.
The object of this invention is to provide a compact and strong construction of as little weight as possible, having the parts so connected as to enable the same all to be quickly arranged on one of the parts provided with wheels to enable the same to be easily moved from one point to another.
The invention embraces many novel features; and it consists in the matters hereinafter described, and more fully pointed out and defined in the appended claims.
In the drawings, Figure 1 is a fragmentary top plan view of a device embodying our invention. Fig. 2 is a side elevation of the elevator and receiving-conveyer. Fig. 3 is a fragmentary enlarged vertical longitudinal section of the same. Fig. 4 is a transverse section of the receiving-conveyer. Fig. 5 is an enlarged side elevation of the lower end of the elevator casing or boot. Fig. 6 is a detail face view of one of the bearing-straps on which the receiving-conveyer is pivoted or hinged on the elevator. Fig. 7 in an enlarged fragmentary section illustrating the detail .of the joints between the parts of the elevatortrough. Fig. 7 is a similar View showing the bolt set up. Fig.8 is an enlarged detail side elevation of the guide and guard for the chain and through which the lower elevator-shaft passes. Fig. 9 is a top plan View of the same. Fig. 10 is a view similar to Fig. 8, but of the guide and guards for the upper run of the elevator-chain. Fig. 11 is a top plan view of the same. Fig.12 is a sectional detail of the hoisting-pulley at the top of the derrick. Fig. 13 is a transverse section of the elevatorspouts.
As shown in said drawings, the elevator and conveyer is shown as generally used that is to say, in connection with an unloading device or wagon-dump, such as that set forth in my application for patent Wagondump, executed of even date herewith. and bearing Serial No. 162,865. Said wagondump comprises a platform A, as shown in Fig. 1, and upon which may be driven a loaded wagon or the like A vertically-movable carriage B extends transversely of the platform and is adapted to elevate the front end of the wagon-box to a height sufficient to permit the grain, corn, or other material-in the wagon-box to flow into a receiving-conveyor D, adjusted at the rear end of the wagon to receive the same. Said carriage may obviously be actuated from any desired source of power. Preferably, however, and as shown in Fig. 1, the same is actuated from a tumbling-rod C, which also actuates the conveyers and the elevator, hereinafter described. Said tumbling-rod may conveniently be actuated by means of horse-power or any convenient source of power. At the rear end of and extending at a right angle from the power side of the platform A, as shown, is the elevator and conveyer, comprising an elevator (indicated as a whole by G) and a receiving-conveyer (indicated by D and located at the rear end of the platform.) Said elevator, as shown, is supported in a portable frame, comprising parallel sills g g, rigidly secured at their front ends to the elongated transverse sill g and at their rear ends connected with a relatively short transverse sill 9 as shown in Figs. 1, 2, and 3. Supported at the outer or front end of the sill g are the parallel vertical ways 9 which are braced rearwardly to the sills g by braces g and laterally to the sill g by braces g Said ways are connected at TCO their tops by the transverse beams g in a fa- I of the sills g, enables said derrick or frame to be moved from place to place, as preferred or necessity may require. Secured at said end of the sills g are boxes 9, in which the tum bling-rod C is journaled and which, asbefore stated, actuates the carriage B. Said tumbling-rod is provided with sprocket-wheels whereby is driven an endless elevator-chain provided with upwardly projecting transverse lags e. A double elevator-trough of sheet-steel, one for each run of the chain, is pivoted at its lower end on said tumblingrod and inclines upwardly between said ways, and sprocket-wheels e are journaled at the upper end of and between the elevatortroughs and over which said chain is trained.
The elevator-troughs are each formed of sheets of metal bent to form an integral bottom and sides, as shown more fully in Figs. 2, 3, 5, and 7, and comprise the lower end portion E, which is rounded and of sufficient radius to permit the chains to pass freely around the elevator sprocket-wheels on the tumbling-rod C and which is rigidly connected with the lower end of the side walls 6 e of the trough by means of a properly-formed or bent sheet of metal 6 to which said ends are rigidly bolted. The adjacent trough-sections are connected through the bottoms e e of said trough-sections and the overlapping integral side walls e e by lapping the metal where the sides and bottoms join each other, with the inner laps directed with the travel of the run of the chain therein, thereby preventing the lags e catching on the ends of the side walls or bottom plates. The ends of the sheets at the laps are apertured and a countersunk washer e secured beneath the same, and a screw-bolt e havinga flat head conical on the under side, such as an ordinary stove-bolt, is secured therein, as shown in Figs. 3 and 7, 7, drawing the metal into said washer, 'countersinking the head therein. Said troughs are connected intermediate their ends by straps of sheet metal. which are secured thereto by means of the bolts which connect the side members of the troughs. The upper ends of said elevatortroughs are connected together by means of the sheet-metal hood E which, as shown, l
comprises the two side plates (2, rounded at the end and open at the bottom, so that material carried up the trough by the upper run of the chain is dumped through said hoodinto any convenient receiving means As shown,
the sprockets e, journaled in said hood at the upper end of said elevator-trough, are provided with a guide 6 for the chains, which acts to prevent the'same from kinking. Said guide is of cast metal or other suitable material, slidably secured below the bottom plate 0 of the upper trough, and affords a bearing for the shaft (5 of the sprocket-wheels e and affords a smooth surface continuous with the bottom for the material to slide over and is rounded at the end to direct material elevated thereto by the chain past the shaft of the upper sprocket. The bottom of said elevatortrough is provided with a similar guide g", rigidly bolted to the bottom plate 6 and through which the tumbling-rod C is journaled. Said guide is also of cast metal and enables any material to be carried out of the end of the conveyer which might fall therein. Said elevator-troughs and contained parts are supported in said frame or derrick by means of a rope or other flexible connection g, which leads through a suitable pulley 9 in the top of said derrick and is secured to the upper end of the elevator-troughs by means of a bail 9 as shown in Fig. 3. The other end of said line extends downwardly along the frame and is secured to a winch 9 to enable the upper end of said conveyer to be adj usted for height as preferred. Conveniently said pulley g is hung from the top of the derrick by means of a barrel-staple or U-bolt 9 over which is secured a strap of metal 9 also bent in U shape and between the sides of which the pulley is journaled.
Means are provided for adjusting the tension of the elevator chain E, comprising guides e, secured on the outer side of each of the side plates 6 of the hood, and between which the bearing 6 for the shaft of the upper sprocket wheels have sliding engagement. gages each of said bearings and passes at its outer end through a suitable strap e extending transversely of the hood. Nuts are provided on each of said bolts on the outer side of said strap, whereby said bearing 6 may be drawn outwardly to secure a desired strain on the elevator-chain. Plates e on the lower end of said elevator-casing. are each provided on its upper edge with transverselycorrugated plates d, rigidly bolted .thereto and adapted to engage with a complementally-corrugated bracket (1, provided with slotted apertures for purposes of adjustment and which is rigidly bolted thereto, as shown in Fig. 2. Said brackets are apertured and afi'ord a bearing for a transverse shaft D, provided with sprocketwheels, which drive the chain d of the receiving-conveyer D and on which the receiving-conveyer is pivoted in such manner that the en tire conveyer may be turned upwardly into the elevator to permit the passage of the team upon the platform A, or when it is desired to move the device. One end of said shaft D projects beyond the bracketd sufficiently to permit a driving sprocket-wheel to be secured thereon which receives the driving-chains d trained over a suitable sprocket on the tumbling-rod C, as shown in A threaded adjusting-bolt e en- IIO Fig. 1 and in dotted lines in Fig. 3. The up 'per run of the conveyer-chain 62 moves along the bottom of a box or receptacle adapted to receive the grain or corn from the wagon when dumped and passes around corresponding sprocket-wheels journaled on the legs d, which are pivoted on and support the outer end of said box. The bearings are provided each with a rearwardly-extending bolt d on each side .of said box, the outer ends of which are threaded and which extend through a transverse beam d, whereby a nut on the outer end'of each bolt acts to adjust the tension on the conveyerchain, as before described, for the elevatorchain. Said receiving-box, as shown, is constructed of sheet metal and comprises'side walls d d and the bottom section (i which extends rearwardly to a point beyond the rear sprocket-shaft. A complemental bottom section (1 extends forwardly above the chain and lags thereon to a point beyond said sprocketshaft, thereby preventing any material in said box from passing outwardly at any other point excepting at the point of delivery to the elevator. The middle part of the side cl" of said boxisrelativelylow, and hinged thereto is the hopper-section d", provided with integral end members d, the inner edges of which are bent inwardly, forming flanges d", which engage against the inner side of the box at each end. Said hopper-section when turned outwardly, as shown in Figs. 3 and 4, is sup ported by said flanged ends. The rear end of the box is formed by a sheet of metal al which flanges over the sides and forms a stay therefor. The front end of the box is of course open, but is partly covered on the top by a sheet of metal (1", which extends downwardly part Way over the inclined end portion, as shown in Figs. 2 and 3, and is securely riveted in position. The metallic side walls of said receiving-box may be flanged, corrugated, or formed in any desired manner to increase the strength, and chute-boards (Z are pivoted on the side wall 6 of the elevatortrough and are adapted to be turned inwardly and downwardly, as shown in Figs. 2 and 3, along the sides of the receiving-box to direct all material therefrom into the elevatortrough. Said chute-boards are turned upwardly when it is desired to turn the receiving-conveyer into the elevator, as before described.
The operation is as follows: The device may be drawn by a single team upon the road or elsewhere with the receiving-conveyer D turned upwardly into the elevator. When desired for use, the platform having been adjusted as shown in Fig. 1, the elevator is suitably adjusted by means of the winch and the device is ready for use. After erecting the device and adjusting the same for use the receiving-conveyer being turned up into the elevator out of the way, a loaded wagon may 'be driven upon the platform until the front Wheels rest on the carriage B and the rear end of the box is positioned to dump the contents thereof into the receiving conveyer. The receiving-conveyer is then turned down to the position shown in Figs. 1, 2, and 3 and the elevator and conveyer started by means of the tumbling-rod C, which also actuates the carriage. The hopper side of the receiving-conveyer is turned downwardly below the rear end of the box of the wagon and (the tail-gate of the wagon being removed) as the front end of the wagon rises the grain, corn, or other material flows rapidly into the receiving-conveyer and is then delivered to the elevator, from whence it is delivered to the granary or crib.
The construction of the chain-tightening devices is exceedingly simple and effective, affording perfect and quick adjustment,while the general construction of the elevator and conveyer troughs is such as to prevent the corn, grain, or other material clogging therein during its passage therethrough. The chain guards prevent kinking the chains, whether the device is operated empty or full.
Obviously many details of construction may be varied without departing from the principles of this invention.
