PROVISIONAL SPECIFICATION.
Improvements in Milk Pails or like Receptacles:
I DAVID JOHNSON of Manor House Warmington in the County of Warwick
Gentleman do hereby declare the nature of this invention to be as follows :-
The invention has reference to receptacles for milk as it is drawn from the udders
of cows or other animals.
The object of the invention is to collect the milk in a vessel or receptacle in
a pure state uncontaminated by extraneous matters.
In the ordinary milking pails there is apt to be received and mixed with the milk,
dirt, hair, dregs, and refuse blown or falling therein.
According to my present invention I intercept and prevent access of such matters
to the collected milk and thereby enhance its value.
On the other hand with the ordinary appliances at present in use the various
matters such as manure, dirty straw, scurf, hair, dust, dirt and other impurities when
once admixed with the milk become practically irremovable by ordinary straining
processes because of the soaking that they have undergone in the warm milk and the
mischief created does not cease there but contaminates and injures not only the milk,
butter and cheese besides causing injury in the cream separation.
In carrying out my invention I employ a pail or receptacle over the opening of
which is fitted a straining and impurity detaining removable cover readily capable of
cleansing from time to time and adapted to receive the stream of milk as it is caused
to flow from the cow or animal without allowing the same to be wasted.
The pail which may be of substantially ordinary dimensions has a cover which may
drop within the top edge of the pail and so that the flange or wall around its edge
may lie against that of the pail and the rim of the same resting on the top ridge of
the pail will prevent the cover passing farther in. Centrally of this cover I provide
a well preferably of oblong or oval form having its wall rising some distance
above the sunken cover and at the bottom of this well I apply fine straining
material.
The cover consists of framing preferably of metal and preferably the rim being of
tin, copper or other metal easily polished. Wood could be employed but its use is
open to objection and the metal should be prevented from rust, and be readily
cleansible in every part.
The larger surface of the cover on the framing and around the central well is
formed of strained very fine hair, wire or like fabric or canvas, flannel, silk or other
suitable textile material.
This filtering cover I find it convenient to make in panels or parts. The well
itself may conveniently be removably fitted into the metal frame of the cover and be
retained in its proper place by a flange thereon. The sieve or filtering surface for
the bottom of the well may be of like material to that already described and formed
on a frame adapted to be dropped within the well and retained by an internal
flange.
The jet of milk from the cow is in milking directed into the centre well and passes
through the straining bottom whilst any milk not so directed is caught by the
surrounding portions of the cover and is similarly strained.
The proportionate areas of the well and the rest of the cover and the relative depths
of the sunk cover and the well will be relatively varied, it being desirable to so
arrange the capacity of the well that it shall be capable of receiving without overflow
each intermittent delivery of milk.
Dated the 15th day of February 1889.

page_text: Fig. 2 shows a plan view of the same.
Fig. 3 shows a like view to Fig. 1, but with the form of the inner chamber
slightly modified in shape by being made shallower, but expanding to a wider surface
at the bottom.
Fig. 4 shows a modification in which the centre or secondary chamber is dispensed
with.
Fig. 5 shows a modification in which the raised outer wall is not employed and the
inner chamber is made movable.
The pail, the top of which is indicated by the lines a, may be of substantially
ordinary dimensions. Applied thereto is a cover which may drop partially or
wholly within the top edge of the pail a, and so that the flange or wall around its
edge, may lie against that of the pail a, and the rim 2 of the same resting on the top
edge of the pail will prevent the cover 6 passing farther in than is desired. Centrally
of this cover I provide a well c, preferably of oblong or oval form, having its
wall c¹ rising some distance above the sunken perforated bed of the cover 63, and at
the bottom of this well c I apply fine straining material c³ which forms a perforated
floor thereto.
The cover b consists of framing preferably of metal, and preferably the rim 62
being of tin, copper or other metal casily polished. Wood could be employed but its
use is open to objection and the metal should be prevented from rust, and be readily
cléansible in every part.
This larger surface 3 of the cover on the framing and around the central.
well c is formed of strained, very fine, hair, wire or like fabric, or canvas, flannel,
silk or other suitable textile material. This filtering cover is generally for
simplicity made in one piece but it can be made in panels or parts.

page_text: The well c is generally made a fixture in the cover b, as it is not necessary to
remove it, but it may be removably fitted into the metal frame of the cover, and be
retained in its proper place by a flange as es, Fig. 5, thereon. The sieve or filtering
surface c³ for the bottom of the well c may be of like material to that already described,
and formed on a frame adapted to be dropped within the well c and retained from
passing further by an internal flange c*.
The jet of milk from the cow is in milking directed into the centre well e and
passes through the straining bottom c³, whilst any milk not so directed is caught by
the surrounding portions of the cover 6 and is similarly strained..
The proportionate areas of the well c and the rest of the cover b and the relative
depths of the sunk cover 63 and the well c will be relatively varied, it being desirablo
to so arrange the capacity of the well c that it shall be capable of receiving without
overflow each intermittent delivery of milk.
Should it be desired to employ pails fitted with spouts to facilitate pouring out of
the contents, a lid or cover to the spout is provided so as to fall over the spout or
lip and prevent ingress of matter.
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
The improvements in milk pails or like receptacles wherein contamination of the
milk by access of dirt and other impurities is prevented by means of filtering media
applied over or about the entrances of such receptacles substantially as heroin-before
described and shown.
