CHECKING THE CONSUMPTION OF LIQUIDS OR SOLIDS
Year: 1885

Woolen Cloth Manufacturer do hereby declare the nature of my invention for
CHECKING THE CONSUMPTION OF LIQUIDS OR SOLIDS to be as follows:-
The object of this Invention is to place a check upon the consumption of liquids
or solids, which are valuable; so that they can not be taken from the vessel in
which they are contained except by the consent of the owner or his representative
who gives a token or check to the person requiring any of the materials, and which
by being dropped through an opening, allows a certain quantity to be drawn out.
The token after use passing down into a receptical which is under lock and key.
For instance the oil used in a Factory may be placed under the controle of the
Foreman by this means, who, by giving a token to anybody requiring oil, allows
them to draw a tin full out. There are several different ways of effecting this
object, but they are all based upon the same principle, viz that of a token or check,
being dropped through an opening, before any of the material can be taken from
the vessel. The arrangement I prefer to use for liquids consists of 2 chain wheels,
one being in the liquid and the other above it. These are connected by a chain
passing over both of them to special links of which at intervals are attached
partially covered cups or buckets, which dip into the liquid become filled, and thus
lift a given quantity out, when the chain wheel is turned one revolution, it being
so arranged, that when the bucket gets to the top, the chain wheel is stopped from
going further, either backwards or forwards, by a double catch, and the cup
empties itself into a spout from which it runs into the can placed to receive it.
The chain wheel can not be wound round again till a token is dropped through an
opening.
This token I prefer to make cheese shape and it runs down a zig zag channel,
and when it gets to the bottom it falls on the tail of one of the catches which lifts
it & allows the chain wheel to be turned one revolution, and bring another bucket
to the ton

page_text: The catch is lifted positively by a cam as it turns round which allows the token
to fall into a box, which is placed under lock and key.
The object of the zig zag channel is to prevent a wire being pushed down on to
the top of the catch, and as a further precaution, I use a pendant catch in the
channel.
This token arrangement may be modified to work with a token of a more
complex shape, which can not be easily imitated. It is also applicable to a hollow,
tap, which can be made to hold a given quantity, and which by a whole or part
revolution discharges itself.

page_text: I, EDWARD EBENEZER EVANS of Brimscombe Court near Stroud, Gloucestershire
Woolen Cloth Manufacturer do hereby declare the nature of my invention for
CHECKING THE CONSUMPTION OF LIQUIDS OR SOLIDS 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 this Invention is to place a check upon the consumption of liquids
or solids which are valuable so that they can not be taken from the vessel in which
they are placed or contained except by the consent of the owner or his representative,
who gives a token or check to the person requiring any of the material, and which
by being dropped through an opening, allows a certain quantity to be drawn out,
the token after use passing down through an opening into a receptical, which is
under lock & key, and in order that the said Invention may be more fully
understood I have annexed hereunto a sheet of Explanatory drawings. Figs. 1 & 2
show sectional views of the arrangement I prefer to use. 1 & 2 are chain wheels
which work in a box 3, the lower portion of which forms a cistern in which the
material (say oil,) is placed. A chain runs on the chain wheels to which are
connected cans or buckets, (two of which are shown at 4 & 5,) at distances apart
equal to the circumference of the chain wheel 1, so that one revolution of the wheel
always brings the cans to the same relative position in regard to it.
Either cast on to the chain wheel, or fastened to the same shaft 6, is the cam 7
shown in Fig. 1.
This cam as shown in the drawing cannot move in either direction, as the catch 8
prevents it moving forward in the direction of the arrow, and the catch 9 prevents
it moving backwards.
In order to turn the chain wheel or cam forward by the handle 10, the catch 8
must be lifted up out of the way & this can only be done by dropping the token 11
through the opening 12. This then runs down the zig zag channel 13 on to the
back part 8 of the catch 8 & lifts it against the swinging weight 14, which however
it does not lift, the token not being heavy enough to do so; the consequence being
that the token cannot fall beyond the catch, till the handle 10 is turned; the
catch 8 is then forced up mechanically by the cam 7, which lifts it high enough to
allow the token to fall clear into the receptacle 15, which is under lock & key.
One turn of the handle brings the can 4, which is full of oil, into the vertical
position 5, & it empties its contents into the trough 16, from which it runs through
the spout 17 to the oil can placed ready to receive it.
From the above description it will be readily understood, that for every token
dropped through the opening 12, a certain quantity of oil or other material, equal
to the capacity of the cans 4 & 5 &c can be extracted.
In order that the catch 8 shall not be lifted by a wire or anything dropped in
the opening 12, & recovered again, the passage 13 is made zig zag, & and the
tongue 18 is introduced, which prevents the token or its equivalent being
withdrawn after lifting the catch.
The above described catch & locking gear is applicable to other measuring
arrangements, which may be substituted for the chain & buckets, such as a hollow
tap, which may be alternately filled & emptied by a whole or partial turn of
the tan

page_text: Having now particularly described & ascertained the nature of my said
Invention, & in what manner the same is to be performed, I declare that what
I claim is
1st The use of a vessel or cistern containing a liquid or solid, which may be
taken from it in certain quantities, by means of the use of a token or ticket.
2nd The use of chain wheels & a chain, to which are attached buckets or cans for
elevating the material to be measured.
3rd The locking arrangement substantially as described,-which is liberated by
a token as shown-and which is applicable to all cases where it is advantageous to
open a lock by means of a token..
