Patented Dec. 6, 1910.
To all whom it may concern:
Be it known that I, FERDINAND J. F ELDT, citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Elevators; and I do hereby declare that the following is a full, 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 has reference more particularly to portable elevators for receiving grain or other material as it is dumped from a wagon, and conveying the same to a bin or other receptacle.
The objects of my invention are to provide conveyin mechanism which operates with comparatively little friction; to provide means for supporting and adjusting the receiving end of the elevator; to provide new means for supporting and adjusting the delivery end of the elevator and to provide details of construction.
In the accompanying drawings, which illustrate my invention, Figure 1 is a side elevation of the complete machine portions thereof being broken away to permit an enlarged view to be shown, the receiving box which delivers to the elevator being shown therein in raised position; Fig. 2 is a large side view of the receiving hopper and the lower end of the elevator, portions of the hopper being broken away to show detailed parts; Fig. 3 shows the standard and the manner of supporting the elevator body in connection therewith, the same being shown pivoted upon the framework of the truck. F i is a vertical longitudinal sectional view of the outer or delivery end of the elevator; Fig. 5 is an enlarged cross section through the outer or delivery end of the elevator; Fig. 6 is a detailed view of the clamp, whereby the elevator is secured at its outer end to the supporting standards; Fig. 7 is a detailed view of the same clamp as shown in Fig. 6; Fig. 8 is an enlarged vertical longitudinal sectional view of the lower end of the elevator; Fig. 9 is a detailed view showing the particular construction of the upper end of the elevator; Fig. 10 is a detailed sectional view of the same part; Fig. 11 is a detail view showing the manner of supporting an elevator in connection with a truck.
This elevator consists of a plurality of pans or buckets which are supported on a frame and connected with the endless carrier so as to travel from end to end of the frame. The frame supports the pans and has the upper and lower pair of angle irons l0 and 11 respectively which form a track, each of said angle irons being arranged with one flange extending vertically upward, and the other flange which forms the track extending inwardly from the vertical flange. The angle irons 10 and 11 at each side of the elevator are connected and held apart by means of the end plates 12 and 13 at the respective ends and intermediate plates 14, which are secured to the vertical flanges of the angle irons and each of said plates is connected with its corresponding plate on the opposite side of the elevator by means of the rods 15, and the intermediate space between the severalplates is braced by means of the cross rods 16. The truss rod 16 connected with the end plates 12 and 13 and carried over the upwardly extending arms 16 is provided as an additional brace which has been found desirable when the elevator is extended to a considerable length.
A series of pansare provided which are indicated at 17 and are open at the top and forward ends and are connected with the chain 18 which passes around the shaft 19 at the delivery end of the elevator, and the shaft 20 at the receiving end of the elevator, and is disposed half way between the sides of the elevator. This chain is provided at suitable intervals with links 21 which are connected at the under side to the conveyor pans intermediate of the width and approximately half way from the real [0 the front so that the forward end of each pan is in close relation to the rear end of the preceding pan. On the bottom of each of these pans, at the sides thereof and on a line with the connection of the pan with the chain, is a bracket 22 which has the flanged roller 23 secured to the end thereof by means of an axial pin, said rollers being disposed in connection with each of said pans in such a position as to engage the inwardly extending flange of the angle irons, which forms a support therefor. The shaft 20 at the receiving end of the elevator is journaled in the side plates 12 and has the sprocket 24 intermediate of the side plates, which carries the chain 18 and each of said plates is provided on the inner face thereof with an articulate flange which forms a continuation of the inwardly extending flange of the lower angle iron, and is formed around the shaft as a center, there being a similar plate to plate 12 on the opposite side of the receiving end of the elevator having a similar flange to flange and supporting the other end of shaft The receiving end. of the elevator is also provided with the shield 27 which incloses the lower end of the elevator and is secured by means of strap irons 28 to the plate 12.
The plates 13 at the outer end of the elevator, to which the angle irons 10 and 11 are secured, are provided with the slots 29, which extend lengthwise of the elevator in termediate of the angle irons 10 and 11, and a plate 30 is provided adjacent the inner face of each plate 13, the latter being provided with a stud projecting through a slot of the former and being provided with a central opening within which the shaft 19 is adapted to be support-ed and around which chain 18 passes, and said plates are movable lengthwise of the elevator. This shaft extends beyond the outer side of each plate 30 through the hearing or stud 31 which is movable lengthwise of slot 29 and each of said bearings 31 is engaged by the threaded member 32 suitably supported in a threaded lug upon the side of each of the plates 13, whereby the shaft and plates 30 may be adj usted lengthwise of the elevator for regulating the tension of chain 18. Each of the plates 30 is provided on the inner face there of with the flange 38 which extends inwardly and bears in the same plane as the inwardly bearing flange of angle iron 10 and describes an are around shaft 19 and serves as a bearing for roller To prevent the escape of grain from the buckets at the upper end of the elevator, there is provided a shield comprising the plates 33 and 33 which extend around the shaft 19 as a center, there being one of such provided on each side of the chain wheel which is located atthe central points on shaft 19 between the two sides of the elevator and suitably secured to the side plates 30. A portion of the closure plates and 33 is cut away as at 33, as shown in Fig. 10, to provide space for the passing of the flanges of the rollers 23 on the carrier pans, the plates 33 and 33" forming the shield, serve to prevent grain from being carried back, and to direct it to the outlet opening.
The hood 37 is carried by the plates 30 at the upper end of the elevator, and the hopper 38 is connected therewith but as the hopper and the swiveled and pivoted conveyer spout which are partially shown in the drawings are no part of my present invention. I will not describe those structures in detail.
The elevator is supported by the truck a3 which has the side rails 1 1. Each of said side rails has a bracket on the inner face thereof and secured thereto adjacent the re ceiving end of the elevator, and each of said brackets is provided with a roller 99 Fig. 11 on the inner face thereof which engages the under face of the inwardly extending flange of the angle irons 11, and thereby support the receiving end of the elevator.
For the purpose of moving the elevator lengthwise of the roller 99 to adjust the elevator to and from the ground, one of the brackets a5 is provided with a forked extension etti above the roller at one side of the elevator, the arms of which are slotted vertically as'at 47. At the same side of the elevator there is provided a screw which extends lengthwise of the elevator and is journaled in the end of the plates 12 and the adjacent plate let. This screw passes between the arms of the forked extension etG and is provided intermediate of said arms with a collar a9 which is threaded thereon and provided with trunnions e5 which rest in the slots 17 of said extension 4E6. At its upper end, the screw 50 is provided with the beveled gear 51 which meshes with the beveled gear 52 which is journaled on a short shaft supported in plate 11, which said short shaft has the squared end 51 to which a crank may be applied to turn the shortshaft for the purpose of operating screw 50. As is apparent, as the screw is turned, the collar e9 being held stationary by its engagement with the slots of the forked extension a6 moves lengthwise of the said screw, thereby moving the elevator lengthwise of the rollers 99.
At the opposite end of the truck from that upon which the elevator is mounted, a stand ard is provided for raising and lowering the outer end of the elevator, which said standard comprises the frame bars one ateach side of the elevator, which are pivoted to the side rails as at 56 and fastened together at their upper ends above the elevator. At each side of the elevator. adjacent the standard is a clamp which is horizontally pivoted to one of the plates 1% on the side of the elevator and loosely embraces the bars to slide lengthwise thereof. This clamp as is shown in Fig. (3, comprises the part 58 which is pivoted to the side of the elevator and has a part 59 pivoted thereto as at 60 and adapted to embrace the bars and to be secured together by cotter pin 61 which passes through the free ends of the part 59 and a lug on the part 58 as shown. To the lower end of one of the bars is secured a bracket 62 which supports the drum and worm wheel shaft 63 and the worm shaft 6 1-. The drum shaft has the drum 65 thereon and the worm wheel (36 which is ei'igaged by the Worm 67 on the shaft 64; and said shaft is provided at its outer end with a crank (38 whereby the worm may be turned to operate the drum. A cable 69 is coiled around the drum, passing over the sheave T0 at the top of the standard, thence down wardly around the sheave 71 on the bracket '72 which is pivotally secured to the elevator, thence upwardly to the top of the standard and secured to the opposite side of the standard from the sheave 70. As is apparent, by the turning of the shaft (34, the delivery end of the elevator is raised or lowered, the clamp in such movement sliding up and down the bars 55. WVhen the elevator is to be transported it may be let down until the lower side rails thereof engage the rollers 73 on the bracket 7a when the clamp may be unfastened and the standard dropped down until it comes to rest on the elevator.
For receiving the grain or other material as it is dumped from the wagon, the receiving box is provided, which delivers to the elevator. This receiving box in the normal receiving condition, is inclined as shown in Fig. 2 and has a shaft 76 at its lower end and shaft 77 at its upper end around which is passed endless conveyer T8, the upper length of which operates in the direction shown by the arrow in Fig. 2, over the floor T9 of the receiving box. The shaft 77 at the upper end of the receiving box projects through slots 80 in the sides of the receiving box and is movable in said slots by means of the tightening screws for tightening and loosening the endless conveyer. This receiving box is horizontally pivoted to the brackets S1 of the elevator by means of the shaft 77 which passes through bearings in said brackets so that the receiving box may be readily swung from the position shown in Fig. 2 to the position shown in Fig. 1. At the outer end. the receiving hopper is cut away at each side as shown at 82 to provide for the chute 83 which may be secured on either side of the receiving box as heretofore shown. At the lower edge of the cut away place 82 and near each end thereof is provided a plate 84: which is grooved as at 85 on the inner face to receive a flat rod. This chute which is preferably of sheet metal is adapted to have a pivotal or hinged connection with the body of the conveyer trough and the chute portion 38 is adapted to be detachably connected with the receiving box so that it may be changed from one side thereof to the other.
The shaft 20 in the bottom of the elevator is designed to receive the application of power by being connected with the tumbling rod of a horse power or other suitable motor. The elevator buckets are driven directly from the shaft 20 and for operating the endless conveyer in the receiving box, a sprocket wheel 96 is provided on shaft 20 and a sprocket wheel 97 on shaft 77 of the endless conveyer and the chain 98 passed. around both of said sprockets. The belt tightener 98 is adjustably supported upon the lower end of the elevator casing as shown in Fig. 2.
