ELEVATOR STRUCTURE Filed April 16, 1936 3mm i? JPSeh wa 7 01am clgchray Patented June 22, 1937 UNITED STA! PATENT QFFICE ELEVATOR STRUCTURE Application April 16, 1936, Serial No. 74,748
Claims.
normal speed is approximately forty revolutions per minute. This is the maximum speed at which the elevator can be run successfully for an increase in speed will result in the cups passing around the pulley so fast that the grain will be thrown high into the air above the top pulley and will fall back onto the pulley and the cups and pass back down the elevator housing to the dump.
The present invention is designed to overcome the foregoing difficulty when the elevator speed is increased, by providing a division board in the top part or head of the elevator structure above the conveyor top pulley, so that the grain when thrown upwardly from the cups, while running the elevator at a high rate of speed, will fall back upon the board and flow therefrom into the discharge outlet of the structure.
The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawing but may be changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claims.
In the drawing:
40 Figure 1 is a view in vertical section of the upper part of an elevator structure showing the improved top construction embodying the present invention;
Figure 2 is a view similar to Figure 1, but illustrating the manner in which the grain passes from the elevator cups when the elevator is running at the usual speed.
Referring now more particularly to the drawing, wherein like numerals of reference designate corresponding parts throughout the several views,
the numeral I indicates the vertical part of the elevator housing in the lower part of which the grain dump is indicated by the numeral 2 while the top or head structure is indicated by the numeral 3.
Within the vertically arranged portion of the housing I are disposed the upper and lower pulleys 4 and 5, respectively, over which pass the endless belt 6, which carries the elevator cups 1. The numeral 8 indicates the usual discharge nozzle or outlet for the elevator which leads into the conveyor 9, and in the operation of the conveyor structure at the normal rate of speed, which is not greater than forty revolutions per minute, the grain as it is brought up by the cups 1 and carried over the top pulley 4 is discharged from the cups into the outlet 8, as illustrated in Figure 2.
Aspreviously stated, an increase in speed of the conveyor structure will result in the grain being thrown up into the air before the cups pass over the top pulley, with the result that it falls directly downwardly between the conveyor belt 6 and the wall of the housing adjacent the outlet opening 8 and most of the grain will pass back to the dump 2.
The present invention comprises the placing of a division board It] in the head portion 3 of the elevator structure directly above and in relatively closely spaced relation with the cups as they pass over the top pulley. This board is disposed at an inclination downwardly toward the outlet opening side of the head of the conveyor housing and has its forward edge arranged to extend over the opening 8 in the manner illustrated so that any grain falling on the board will flow downwardly and fall directly through the opening into the carry-off chute 9. The rear or high edge of the division board I0 is disposed over the conveyor belt top pulley between the center there of and the side remote from the outlet 8. By this means, when the conveyor belt is run at a high rate of speed, the grain will be thrown into the air as the cups start to turn over the top pulley, across the rear edge of the board, and will curve forwardly and downwardly to fall on top of the board, as shown in Figure 1, from which it will run into the outlet 8 from the forward edge of the board.
From the foregoing, it will be seen that with the invention herein disclosed, it will be possible to operate the conveyor or elevator at a higher rate of speed than has been heretofore possible and that the same elevators may now be made to do twice the amount or more of Work than has heretofore been the case.
While in the specification the member in has been referred to as a division board, it is to be understood that this is not intended as a limitation in any respect with regard to the material of which this part may be made, as it is obvious that the same may be made of metal, Wood or any other suitable material.
What is claimed is 2- 1. In an elevator structure, including a vertical housing having a top cover, an outlet and an endless cup system for raising material from the lower part of the housing into the upper part, and
means arranged in the upper part of the housing above the conveyor system upon the top of which material may fall after being projected upwardly from the conveyor cups when the conveyor is operated at high speed, to flow into the said outlet.
2. In an elevator structure, including a housing having a top casing, a laterally disposed outlet and a conveyor system including an endless belt carrying cups arranged to follow vertical paths, a receiving board disposed in the upper part of the housing over the conveyor system and having a forward downwardly directed discharge edge disposed adjacent said outlet, and a rear edge arranged relative to the conveyor system whereby at a predetermined rate of speed the material of the cups of the system will be thrown upwardly and onto said board.
3. In an elevator structure, a vertically disposed housing having a relatively large closed top, a material outlet directed downwardly from said top and disposed at one side of the housing, a pair of pulleys disposed in spaced relation one above the other, an endless belt encircling the pulleys and carrying the material conveying cups, the uppermost one of said pulleys being disposed at an elevation above said outlet whereby at a normal rate of speed of the pulleys the material of the cups will be discharged laterally and downwardly through the outlet, and a division board disposed transversely of the housing top above the uppermost pulley and having a forward discharge edge disposed over the outlet, and a rear edge disposed over the uppermost pulley, said board being inclined toward the outlet whereby material thrown upwardly by the cups in the operation of the pulleys at a high rate of speed will fall onto the board and flow therefrom into the outlet.
4. The combination with an elevator designed to handle granular material and to operate at a high speed and a top housing having an outlet, of a structure disposed in the housing and covering the return run only of the elevator, which is so arranged that material thrown upwardly from the elevator will rise above the structure and be intercepted and directed toward said outlet as it falls.
5. The combination with an elevator designed to handle granular material and to operate at a high speed and a top housing having an outlet, of ardivision board extending transversely of the housing above the elevator and inclined downwardly toward the outlet, the high side edge of the board being in a vertical plane passing between the runs of the elevator and the board extending across the downwardly moving or return run of the elevator.
