HOPPER FOR STORING IBINS.

Application filed October 16, 1925.

This invention relates to hoppers for storing bins.

l/Vhen delivering material stored in bins having ordinary hoppers or spouts, the center and upper portions of the material in the bins passes out before certain of the lower portions are delivered. Consequently,.when bins are continually replenished and rarely emptied, certain of the grain will remain in the bins for long periods of time.

Therefore, the principal object of this invention is to provide for storing bins, a hopper designed to deliver from a storing bin, a stream of divided material, the particles of material being distributed uniformly throughout the cross sectional area of such stream, thereby causing such material to leave the bins in substantially the order in which the particles were received.

To more specifically state the object, the grain first received by a bin will be first delivered therefrom and the grain last received will be last delivered by reason of the peculiar manner in which the hopper, hereinafter described, operates.

A further object is to provide a spout for feeding grain into a storing bin and adapted to spread the grain in a uniform stream throughout the cross sectional area, thereby so to arrange the supply of grain with a substan tially level surface. In so distributing the supply, accomplishment of the object first mentioned is facilitated.

Before passing on to the description of this invention, it may be well to mention that the first and second objects can be accomplished by identically the same device. One object being accomplished by reversing the operation of the device from that by which the other object is accomplished.

In the drawings:

Fig. 1 is a fragmentary sectional elevation of a storing bin showing in section the hopper as applied thereto for delivering to and from the bin a quantity of grain.

Fig. 2 is a horizontal sectional view taken on the line 22 of Fig. 1.

Fig. 3 is a horizontal sectional view similar to Fig. 2 showing a slightly modified form of bin and hopper.

Like parts are identified by the same reference characters throughoutthe several views.

Serial No. 62,736.

from such bin for the reason that grain will be delivered simultaneously from all portions of the bin and substantially in the order in which it is received by the bin. It is, however, optional with the individual as to the use of such hopper as a spout for delivering such material to the bin.

The hopper H and spout S shown in Fig. 1 are identical in construction, each comprising a plurality of frusto-conical bell portions 2, 3, 4 and 5, each portion having in tegral tubular sections 6, 7, 8 and 9, respectively. Each of the bell portions are substantially concentric and spaced apart to provide annular openings communicating with the space in the bin. Each of the tubular portions are substantially concentric and spaced apart to provide annular openings each communicating with corresponding annular openings between the bell portions, the tubes 7, 8 and 9 terminating at their outer ends in a plane passing through the integral connection of hell portion 2 and tube 6.

In applying this invention as a hopper or spout to storing bins, it has been found that certain mathematical proportions should be maintained in order that the stream of grain delivered to or from bins should be uniform throughout the cross sectional area of such bins. To illustrate: the cross sectional area A of the bin 1 shall be in proportion to the cross sectional area of the opening B between bells 2 and 3 as the cross sectional area G of the space in tube 6 is to the cross sectional area of the opening D between tubes 6 and 7. To further illustrate, area A is toarea E as area 0 is to area F.

When a hopper of the type disclosed herein is used as a spout to deliver grain to a storing bin and the proportions indicated are maintained, such grain will be spread in the bin to form a substantially horizontal surface on such grain. /Vhen the hopper is used to deliver grain from the bin and the proportions are substantially as indicated above, grain adjacent the walls of the bin will be fed therefrom at a rate substantially equal to the rate at which grain at the center of the bin will be fed and consequently all of the grain will be removed from the bin regardless of whether or not such grain is continually replenished.

A hopper constructed as indicated in Fig. 3 will operate in substantially the same man ner as the hopper shown in Fig. 2. In other words, the geometrical shape ot a storage bin and hopper does not alter the manner in which the hopper operates, provided the proportions of the hopper are maintained as has previously been noted;

From the foregoing description, it is evi dent that the invention disclosed herein may be alternatively used as a spout for delivering grain to a storage bin or as a hopper for delivering grain from a storage bin; that when the invention is used as a spout, the gain is uniformly spread throughout the cross sectional area of the bin; and that when the invention is used as a hopper, the grain is simultaneously taken from all parts of the bin, thus preventing any of the grain from remaining in the bin when thesupply is beingcontinually replaced.
