COMPLETE SPECIFICATION,
Improvements in or relating to Feeding Devices for Granular
Materials.
I, GEORGE BARKER of 77 Colmore Row Birmingham in the County of Warwick
Consulting Engineer do hereby declare the nature of the said invention as com-
municated to me from abroad by Hugh Monticello Whitney of No. 11 Morse Avenue
in the City of Liberty, County of Clay, State of Missouri, United States of America,
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
The object of the invention is to provide a hopper with a feed-gate which will act
automatically so as to feed any class of stock with evenness and regularity; and it
consists, essentially, of a light metal gate suspended over the opening in the hopper on
the points of two adjustable pivot-pins, the said gate being arranged in connection
with a
spring arranged so that its tension may be increased or decreased to suit the
weight of the grain in the hopper and the thickness of the feed desired.
Figure 1, is a perspective view of a hopper provided with my improved gate located
inside the said hopper.
Figure 2, is a perspective sectional detail of the adjustable pivot-pin used in
connection with the device shown in Figure 1.
Figure 3, is a perspective detail of a hopper provided with my improved gate
located outside of the said hopper.
Figure 4, is a perspective detail of the adjustable pivot-pin used in connection with
the device shown in Figure 3.
In the drawing, A, represents a hopper, and B, its feed roller.
I do not confine myself to any particular style, size, or kind of hopper or feed roller
as my invention is applicable to all kinds of hoppers whether used in connection with
a roller mill, a purifier, or a wheat cleaner.
C, is a light metal plate pivotted on the points of the adjustable pivot pins, D, and
forming the feed-gate of the hopper, A.
In Figure 1, the feed gate C is pivotted inside of the hopper, A, in which
construction the pivot pin, D must necessarily also be inside the said hopper. As
shown by Figures 1 and 2, in this construction each pivot-pin d is screwed through a
plate E and is provided with a nut F.
The hole in the end of the hopper A through which the pivot pin D passes is made
sufficiently large to enable the ready adjustment of the pivot-pin, D. The said hole is
however is effectually covered by the plate E. This plate, E, is secured to the end of
the hopper by the screws G, and, H, the screw, G, passing through an elongated hole
in the plate, E, and the screw H through a large circular hole. In this
way
it is
simply necessary to loosen the screws G, and, H, in order to adjust the pivot pins D,
in any direction which may be necessary in order to put the feed-gate, C, in proper
alignment with the feed-roller, B.
In Figures 3, and 4, it will be noticed that the pivot pins, D each pass through an
elongated hole in a bracket I, which is secured to the face of the hopper by screws J
which pass through elongated holes made in the said bracket.
K, is a post, fixed to and projecting from the face of the feed-gate (. This post K,
connected as indicated, to a spindle L, the opposite end of which passes through a
hole in the lug M, fixed to the face of the hopper A, a nut N, being screwed on to the
spindle L, and a spring O, placed between the said nut and the lug M.
By adjusting the nut N, the tension of the spring O may be easily regulated so as
to impart a greater or less pressure on the gate C, as circumstances may require.
In this way a heavy stream or a light stream may be effected on to the feed-roller B,
with evenness and regularity and the pressure on to the feed-gate may be easier
regulated so as to suit any weight or class of stock.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
:―
1st. A feed-gate for a hopper supported on the points of adjustable pivot pins;
substantially as and for the purpose herein specified.
2nd. A feed-gate for a hopper supported on the points of adjustable pivot-pins in
combination with a spring provided with means for regulating its tension and arranged
to impart an elastic pressure against the pivotted feed-gate; substantially as and for
the purpose specified.
