HOPPER.

Specification of Letters Patent.

Patented Dec. 1d, 1915.

Application filed December 24, 1914. Serial No. 878,898.

To all whom it may concern:

Be it known that I, ED ARD P. KENDALL, a citizen of the United States, residing at Bowdoinham, in the county of Sagadahoc and State of Maine, have invented a new and useful Hopper, of which the following is a specification.

The present invention appertains to hoppers, and aims to provide a novel and improved hopper for drawing oil various materials from bins, and the like.

' One of the objects of the invention is to provide a valve or shutter assembled with the hopper in a unique manner, for cutting ol'i the flow of material through the discharge opening of the hopper, the parts being so arranged that the material will run oii of the valve or shutter and will not cling theretn or lodge thereupon when the valve or shutter is opened.

Another object of the invention is to provide novel means for mounting the valve or shutter for movement, in a mostefliective manner, to open and close or control the passage through the discharge opening of the hopper.

A still further object of the invention, is the provision of'a novel actuating mechanism for the cut-off valve or shutter.

It is also within the scope of the invention to provide a hopper device of the nature indicated, which will be comparatively simple, compact, non-encumbering and inexpensive in construction, which mav be readily assembled and taken apart, which is provided with adjusting means for adjusting the valve or shutter relative to the actuating means, and which is convenient, efficient and thoroughly practical in use.

\Vith the foregoing and other objects in view which'will ap earas the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention is illustrated inits preferred embodiment in the accompanying drawing, wherein- Figure 1 is a side elevation of the improved hopper, with the valve or shutter in closed position. Fig. 2 is a vertical section of the structure, with the valve or shutter swung open. Fig. 3 is a reduced bottom view of the structure, with the valve or shutter closed.

The hopper proper or hopper body 1 is preferably in the form of a casting, and its upper edge is provided with an outstanding rim or flange 2 for bolting or otherwise securing the hopper to the bottom of a bin, or other support, so that the material may be discharged or run into the hopper so as to be dispensed through the lower discharge open ng 3 of the hopper. The discharge openlng 3 is disposed obliquely or in an inclined position, and the side edges 4 of the opening 3 are curved upwardly from the lower end ofthe inclined wall 5 of the hopper, to the lower end of the opposite wall 6 of the hopper. The walls 5 and 6 of the hopper are relatively long and short, so that the curved edges 1 of the other walls of the hopper will be arranged as specified, and to dispose the discharge opening 3 in the oblique or inclined position. The cut off valve or shutter 7, which is also preterably in the form or" a casting, is curved to fit snugly against and move along the curved edges at and the side edges of the valve or shutter 7 are provided with up turned flanges or lips 8 extending partially over the respective side walls of the hopper.

In order to mount the valve or shutter 7 for oscillatory movement to open and close the discharge opening 3 of the hopper, the side edges and flanges 8 of the valve are provided with outstanding lugs or ears 9 between the upper and lower edges of the valve. and the end portions of a Usl1aped or bail-like hanger rod 10 are engaged downwardly through the lugs or cars 9. while the intermediate or yoke portion of the hanger rod 10 is fulcrumed or pivoted upon lugs 11 outstanding from the wall 5 of the hopper adjacent or immediately below the rim or flange 2 of the hopper. diate or yoke portion of the rod 10 is pivotally engaged between the lugs 11 and hopper rim 2, against the wall 5 of the hopper, and the rod 10 straddlesthehopper. The edges 4 and valve 7 are curved about the aXis of the yoke or intermediate portion of the rod 10, or a' line running between the lugs 11 and hopper rim 2, so that when the valve is swung with the rod 10, it will move properly along the edges 4 of the discharge opening 3. Nuts 12 are threaded upon the ends of the rod 10 and bear against Thus, the intermethe ears or lugs 9 for holding the valve 7 snugly against the edges 1, it being noted that when the nuts 12 are loosened and removed, the valve 7 and rod 10 may be sepa rated, and the rod and valve may then be removed from the hopper readily.

The actuating mechanism for opening and closing the valve 7, embodies a trans verse rod or shaft 13 journaled through bearings 11 secured to the rim 2 of the hopper at the upper end of the wall 6, the rod or shaft 13 having a downwardly projecting or depending lever arm 15 at one side of the hopper, and a similarly projecting or depending arm 17 adjacent the wall 6 of the hopper. The lower end of the lever arm 15 is equipped with a suitable handle 1.6 in order that the lever 1517 may be readily swung for controlling the valve. The arm 17 is connected to the valve 7 by means of a link 18, which is provided with a fork or bifurcated portion 19 at one end straddling the lower or free end of the arm 17, and pivoted thereto by means of a bolt or pivot element 20, and the other end of the link 18 ispivoted between a pair of depending or downwardly projecting ears or flanges 21 carried by the bottom of the valve 7. The ears or flanges 21 are preferably located centrally of the valve, and a removable bolt or pivot element 22 is engaged through the ears 21 and respective end of the link 18, the ears 21 being preferably provided with a series of apertures 23 for the engagement of the bolt 22 whereby the bolt may be removed and adjusted along the ears or flanges 21, to adjust the relation of the valve 7 and its actuating means or mechanism.

By swinging the lever arm 15, the valve 7 may be conveniently controlled, the parts being so arranged that when the arm 15 is swung to the position illustrated in Fig. 1, the arm 17 of the lever will swing adjacent 1 the wall 6 of the hopper so that the link 18 will push the valve 7 to closed position. It is to be noted that when the valve 7 is swung to closed position. the arm 17 and link 18 will tend to straighten out, so that the valve 7 will move relatively slow when it is at its closed position, and will move relatively fast when at its open position, as seen in Fig. 2. In other words, the movement of the valve is accelerated in order that it may be quickly moved to and from a completely open position, and in order that the valve may be accurately or nicely set when partially closed, since the valve will move relatively slow with respect to the movement of the lever arm 15. In this manner, the operator or attendant may quickly cut off the flow of the material from the hopper, at the opportune moment, and may conveniently swing the valve 7 at a desired distance from the wall 5 of the hopper, to allow a certain restricted flow of the material. It is also to be observed that when the valve 7 is opened, it is swung upwardly, so that whenever the handle 16 is released, the valve will gravitate to a closed position of itself, to automatically cut off the flow of material. Furthermore, the valve is so positioned that the material thereon will readily run off of the same to prevent the material lodging upon the valve when it is opened. By adjusting the bolt or pivot element 22, the valve 7 may be adjusted relative to the actuating mechanism, so that when the lever 1517 is swung to close the valve 7, a predetermined slot or gap may be provided between the valve 7 and hopper wall 5. The valve or shutter 7 may be operated easily even when subjected to considerable pressure due to the weight of the material within the hopper.

What is claimed is:

1. A hopper having a lower outlet, a bailshaped hanger straddling the hopper, one wall of the hopper having means receiving. the yoke portion of the hanger for fulcruming the same to the hopper, the side edges of the hopper outlet being curved about the fulcrum of the hanger as a center, a valve engaged upon the end portions of the hanger and movable along the said edges of the outlet, and adjustable elements engaged upon the ends of the hanger and bearing against the valve to hold the same against the said edges of the outlet. 7

2. A hopper having opposite relatively long and short walls and an inclined outlet between the lower ends of the said walls. a U-shaped hanger straddling the hopper, the relatively long wall of the hopper having means receiving the yoke portion of the hanger for fulcruming the same thereto, the side edges of the outlet being curved about the yoke portion of the hanger as a center, a valve engaged upon the end portions of the hanger and movable along the said edges of the outlet, adjustable elements engaged upon the ends of the hanger to hold the valve against said edges,.a lever fulcrumed to the hopper adjacent the relatively short wall thereof, and a link connecting the lever and valve.
