GRAIN-DISTRIBUTER..

Specification of Letters Patent.

Patented Jan. 11, 1910,

Application filed November 25, 1907. Serial No., 403,836.

To all whom 'it may concern:

Be it known that I, CHRISTIAN WV. CAMP, citizen of the United States, residing at Metamora, in the county of V'Voodford and State of Illinois, have invented certain new and useful Improvements in Grain-Distributers; 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 relates to grain distributing mechanism for granaries.

The primary object of my invention is to provide means by which grain can be carried to an extremely high point in the top of the granary before being delivered into the receiving bins. Ordinarily it is not possible to distribute the grain' from a very high point on account of the structure of the means usually employed for that purpose.

It is my purpose to provide means by which bins of the greatest height can be filled with grain so that a greater storage capacity can be had.

In the appended drawing, Figure l is a vertical longitudinal section of a portion of a granary showing its ridge pole and the bins with my invention shown in position for use, part of the same being shown in section and certain working parts removed. Fig. 2 is a plan of the head of an elevator showing a conveyer and driving mechanism beneath it. Fig. 3 is a side elevation of the conveyer, the elevator-head and the connection between them and also showing the gearing therefor. Fig. 4 is a transverse section of part of one of the conveyers showing portions of the gearing. Fig. 5 is a view of a shiftable sleeve or clutch.

A indicates the ridge pole of a granary and B the storing bins.

C is an elevator such as is commonly used for elevating grain, while D and E represent two inclined conveyer sections connected at their lower ends and into which the elevator discharges its grain, the upper free ends being suitably hung from the roof of the building. The upper ends constitute the discharge ends and are provided with suitable movable distributing spouts F which may or may not be used and which, if used, may be of an desired length and inclined at any angle. uspended from the elevator head by means of hangers G is a hopper I-I for receiving grain from the elevator and delivering it to the conveyer, said hopper, however, may be dispensed with and the elevator may discharge directly into said conveyers if desired.

At J are hangers secured to the hopper, their lower ends being connected and braced by a yoke K, Fig. 3, said hangers also having a member L connected to and between them above said yoke, which is also shown in Fig. 4. This latter member constitutes a bearing for a shaft M, Figs. l and 4, for the conveyer drag to be described, said shaft providing a pivotal support for the two conveyer sections, there being one of the said plates L at each side of the conveyer though only one of them is shown.

N indicates a sprocket wheel on the shaft M, Figs. l, 2, and 4, beneath which run sprocket chains O carrying the usual flights P said chains O carrying the usual flights while at each side of each said wheel N is an idler Q, the latter being suitably carried on any portion of the device and serving to hold the drag in pro er driving relation with said sprockets N. ISuspended from the hopper by means of hangers R within the conveyer, are idlers R', but one of which is shown, beneath which the chains run and by means of which the latter are held upon the bottoms S of the conveyer sections.

On one end of the shaft M, outside the conveyer, is a beveled gear T and extending at right angles to said shaft and having bearings in the hangers J is a shaft U having thereon two beveled gears V W said gears being free to turn upon said shaft, both meshing, however, with the said gear T. One end of the shaft U carries a sprocket wheel 2 and a sprocket chain 3 serves to transmit motion thereto from a shaft 4 at the elevator head through a sprocket wheel 5. Mounted upon and shiftable along said shaft U between the gears V, vW is a sleeve 6 having a longitudinal slot 7 through which extends a pin 8 carried by the shaft U, Fig. 5, whereby the sleeve is made to revolve with said shaft.

As shown in Fig. 2, the adjacent ends of the hubs of the gears V YV are provided with notches 9 and the sleeve 6 described is provided with projections or lugs l0 adapted to engage said notches. The sleeve 7 is further provided with annular flanges l1 loe- I tween which and straddling the sleeve is a j forked shifting-lever l2 pivoted at 13 toI the yoke K described. The mechanism thus i arranged serves to drive the drag of the' conveyer sections in either direction, said| drag, as shown by the figures, consisting of but a single length extending through oth sections; the shaft l of the elevator imparting a continuous motion to the shaft U. lf the sleeve which constitutes a clutch be shifted into ene'agement with one or thel other of the gears V, lV, the drag will be driven in one direction or the other through the gear T. By this means grain delivered by the elevatorinto the conveyer can be clevated and discharged from either one of the sections.

As already stated herein, the shaft M constitutes a pivot for both conveyer sections so that said sections may be adjusted for height to accommodate any pitch of roof.

Tvlhen setting up the apparatus in the building the elevator is placed in position, i the conveyers suspended in place and adjusted with their discharge ends as high as possible beneath the roof of its ridge pole. Though not shown, any suitable means may be used by which to prevent grain being lost from the conveyer sections where they join. rEhe adjacent ends of the bottoms S are separated in order to allow the movement of the section, and in order to provide a closed bottom, l have provided a iiexible metal plate at let which bridges the gap between said bottoms and one end may be secured in place while the other may slide upon the opposite bottom portion.

ln order that the drag may accommodate itself to various strains have provided a boxing at l5 at the free end of the conveyer, Fig. 3, which is slidable in guides 1G there being a slot 17 in the conveyer to permit the shaft to shift. A compression spring 1S bears against one side of the said boxing its other end resting against an ear lt) on the conveyer. The boxing will thus be normally held by the spring so'as to keep the proper j tension upon the drag and at the same time as the convevers are moved allow said drag to shorten or lengthen. Although I have compensating deshown but one of these vices one is also used upon the opposite conveyer. may use but one of the conveyer sections but in using both l am enabled to deliver in two directions as shown. lt is also evident that the conveyer may be arranged at right angles to the ridge pole as well as parallel thereto.

F rom the foregoing it can be seen that although the elevator may discharge grain at a point some distance below the roof of the building yet by using an inclined conveyer I am enabled to readily elevate the grain to the highest possible point for its distribul tion and having this in mind, as well as any structure the equivalent of that desc 1ibed by which this object can be acomplished,
