PROVISIONAL SPECIFICATION,
An Improved Machine for Automatically Weighing Seed, Grain,
Cereals, and other substances for the Purpose of Obtaining a More
Even Mixing of Different Qualities of materials or substances,
I, GEORGE ROSLING, of Victoria Flour Mills, Hull, in the County of Yorkshire,
Mill Manager, do hereby declare the nature of this invention to be as follows:-
The object of my invention is to provide an improved weighing machine for
automatically weighing quantities of grain, seed and other suitable materials or
substances for the purpose of obtaining a more equal mixing of the grain or
the like being mixed than is the case with the contrivances at present in use
for such purposes, these contrivances being known as capacity measures, by the
employment of which it is impossible to obtain a good and satisfactory mixing,
as the difference in the quality of the substances being measured and mixed
materially affects the quantity of the substance which the capacity measures will
hold, as for instance, in the measuring and mixing of wheat where capacity
measures are employed, if, say, two of such measures are connected to two silos
or bins containing each the same quantity of wheat, a good quality of wheat
being in one bin and a poorer quality in the other bin, it will be found that the
capacity measure connected with the bin containing the better quality will have
measured off the contents of the bin it is connected to before the capacity measure
connected to the bin containing the poorer quality has measured off the contents
of its bin, it will therefore be understood that as the wheat is fed to a conveyor
from such capacity measures there is not an even mixing of the two qualities of
wheat with my invention this is obviated as the wheat is weighed instead of
being measured, and each weighing machine weighs the same quantity of wheat
or the like in the same space of time, and therefore even quantities of wheat or
the like are dropped by each machine on to the conveyor, or deposited where
required, by this means obtaining an even mixing which has hitherto been
impossible.
For the purpose of my invention, I employ a weighing machine consisting of
a feed hopper provided with jaws at its bottom, such jaws being opened and
closed by means of links connected thereto. I employ a beam scale to one end
of which is suspended a hopper or receptacle for holding the grain or material
being weighed, this receptacle has hinged or pivotted doors at the bottom, such
doors being provided with weights or controlling levers by means of which the
said doors are opened or closed as required during the process of weighing, stops
fixed preferably on the frame or casting which supports the scale are employed
for actuating the weights or controlling levers which operate the said doors.
At the other end of the scale beam aforesaid the weight is suspended, and the
beam is continued to form a projecting rod or the like which is immediately
above a cam mounted on the driving shaft of the machine.
The apparatus is fitted in a suitable frame or casting, and any number of the
machines may be connected to the same shaft and driven at the same time.

page_text: My improved weighing machine works as follows;
The wheat or other material or substance being weighed is run into the feed
hopper, the beam of the scale when the scale hopper is empty presses on the
bottom of the links forcing them up and opening the jaws of the said feed
hopper which allows the required quantity of wheat or the like to fall into the
scale hopper which lowers when it has the required weight, this shuts off the
supply from the feed hopper, as the jaws close immediately the scale beam ceases
contact with the links; during the time the scale hopper is filling the cam is
turning on the driving shaft and as its elongated end comes to the top, it comes in
contact with the projection on the end of the beam and tilts it up the scale
hopper lowering at the same time, the weights or controlling levers attached to
the hopper doors come in contact with the stops which raise such levers and so
open the said hopper doors thereby releasing the wheat or the like and depositing
it on to a conveyor or into a suitable receptacle as required.
When the hopper is emptied of its contents it rises and the operation of weigh-
ing goes on automatically as before.

An Improved Machine for Automatically Weighing Seed, Grain,
Cereals, and other substances for the Purpose of Obtaining a More
Even Mixing of Different Qualities of materials or substances.
I, GEORGE ROSLING, of 3, Endsleigh Place, Newland Avenue, Hull, late of
Victoria Flour Mills, Hull, aforesaid, in the County of Yorkshire, Mill Manager,
do hereby declare the nature of this invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the follow-
ing statement:~
The object of my invention is to provide an improved weighing machine for
automatically weighing quantities of grain, seed and other suitable materials
or substances, for the purpose of obtaining a more equal mixing of the grain,
or the like being mixed than is the case with the contrivances at present in use
for such purposes, (these contrivances being known as capacity measures,) by
the employment of which it is impossible to obtain a good and satisfactory mix-
ing; as the difference in the quality of the substances being measured and mixed
materially affects the quantity of the substance which the capacity measures
will hold; as for instance, in the measuring and mixing of wheat, where capacity
measures are employed, if, say two of such measures are connected to two silos
or bins containing each the same quantity of wheat, a good quality of wheat being
in one bin and a poorer quality in the other bin, and set to deliver equal quan-
tities, it will be found that the capacity measure connected with. the bin contain-
ing the better quality will have measured off the contents of the bin it is con-
nected to before the capacity measure connected to the bin containing the poorer
quality has measured off the contents of its bin; it will therefore be understood,
that as the wheat is fed to a conveyor from such capacity measures there is not
an even mixing of the two qualities of wheat. With my invention this is
obviated, as the wheat is weighed instead of being measured and each weighing
machine weighs the desired quantity of wheat or the like in the same space of

page_text: time, and therefore accurate quantities of wheat or the like are dropped by such
machine on to the conveyor or deposited where required, by this means obtaining
an exact mixing, which has hitherto been impossible.
DESCRIPTION OF DRAWINGS.
Fig. 1 represents a side view of my improved weighing machine with frame
removed, and shewing feed spout for feeding purposes.
Fig. 2 is a front view but with scale mounted in frame.
Fig. represents a plan view of Fig. 2 and
Fig. 4 shows side elevation of one side of casting or frame.
For the purpose of my invention, I employ a weighing machine consisting
of a double beam scale, to one end of each of the beams A A of which is sus-
pended a hopper or receptacle B for holding the grain or material being weighed,
this receptacle has two hinged or pivoted doors or jaws C at the bottom, which
are provided with links, or in place of the links, studs 1 1, stops or a double
inclined slide E fixed preferably on the inside of the frame or casting F which
supports the scale, is or are employed for actuating the controlling links or
studs D D which operate the said jaws C.
At the other end of the scale beams A. A aforesaid to those which take the
hopper or receptacle B, the weights are suspended on a weight plate G carried
by rods H depending from such beams A A, these rods may be connected at
their top ends by a stay H' for giving greater rigidity to them and preventing
them moving independent of each other, and one beam is continued to form a
projecting rod or the like J which is immediately above a cam K mounted on
the driving shaft M of the machine.
If desired the projecting rod J may be run from a cross stay or cross stays L L
Fig. 3 used for strengthening or giving rigidity to the beams A. A.
The apparatus is fitted in a suitable frame or casting F which supports it and
forms the sides, and any number of the machines may be connected to the same
shaft and driven at the same time. Over the scale receptacle BI employ a
hopper or feed spout N provided with jaws 0 at its bottom, such jaws having
links P which are opened or closed by means of one or both of the beams A A; when
the receptacle B is filling, the links Prest on the beam or beams A A of the scale and
so keep the jaws open, when the receptacle is full it lowers and the beam clears the
links, the jaws closing by means of their own weight thus stopping the feed.
The scale can be regulated by means of the rods H which have their bottom ends
threaded to take the weight plate G, and thumb and finger screws R R; by
highering or lowering the weight plate the scale can be regulated to a nicety to
allow of the density of the feed being increased or decreased as desired. The
driving shaft M upon which the cam K is mounted may be driven in any suit-
able manner.
My improved weighing machine works as follows:-
The wheat or other material or substance being weighed is run through the
feed hopper or spout N, the beam or beams A A of the scale when the scale
hopper or receptacle B is empty presses on the bottom of the links on the
jaws O of the feed spout forcing them up and opening the jaws of the said feed
spout which allows the required quantity of wheat or the like to fall into the
scale hopper or receptacle B which lowers when it has the required weight in it,
this shuts off the supply from the feed hopper as the jaws O close immediately
the scale beam A ceases contact with the links P: during the time the scale
hopper is filling the cam K is turning on the driving shaft M, and as its elon-
gated end comes to the top it comes in contact with the projection J on the end
of the beam or cross stays so lifting it up the scale hopper lowering at the same
time, the controlling studs D D attached to the hopper doors or jaws C come
in contact with the inclined slide E and the action of such studs sliding along in
opposite directions opens the said hopper doors, thereby releasing the wheat

page_text: or the like and depositing it on to a conveyor or into a suitable receptacle as
required.
When the hopper is emptied of its contents it rises and the operation of
weighing goes on automatically as before.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
claim is;
-
1. An improved weighing machine consisting of a receptacle B suspended
from one end of a beam or beams A A, and having articulated jaws C at its
bottom, provided with links or studs such as D 1, and weight plate G sup-
ported by rods such as H, with or without screws R R suspended from the other
end of the beam or beams A A of the scale, a projecting rod J, cam K on driv-
ing shaft M, and frame or casting F, for taking the centre pivots of the scale
and with or without feed spout such as N, provided with jaws 0, and links P,
in the manner and for the purposes, substantially as shown and described.
2. In connection with weighing machines such as described in Claim 1, the
employment of a feed spout such as N, provided with jaws O having links P,
the whole being placed over the scale for feeding the scale receptacle, and being
operated by means of the beam or beams A A of the scale, in the manner and
for the purposes, substantially as shown and described.
3. The combination of the herein before mentioned parts to form an automatic
weighing machine, with or without feed arrangement, in the manner and for the
purposes, substantially as shown and described.
