I, JOHN BYWATER, of 130, Castle Street, Edgeley, Stockport, in the County of
Chester, Joiner, do hereby declare the nature of this invention to be as follows:-
This invention relates to cans bottles, jars or similar vessels for containing
milk or other fluids, the object being to provide such cans or vessels with an
appliance whereby splashing or waste by spilling the contents is avoided without
the necessity for special lids or expensive devices.
The invention consists of a float made to fit the inside of the can or vessel
(which may be of any suitable vertical sided form) and at the same time to rise
or descend freely in the said can or vessel; this float is hinged so that it can be
folded for insertion through the somewhat contracted mouth of the can or for
allowing the can or vessel to be more completely emptied; it is also made with
an opening or a series of openings to allow any steam or vapor arising from the
milk or fluid when warm to rise and escape through a suitable ventilator or open-
ings in the lid of the can. For cans from which the milk or fluid is to be with-
drawn by a dipper or ladle the opening is a large one in the centre of the float
which is then in the form of a ring or the like when floating on the milk or fluid,
through which the largest dipper or ladle can be inserted.
The float and its hinges may be made of any suitable material not injuriously
affected by or affecting the milk or fluid. I prefer to make the float of wood in
two thicknesses, the grain of one thickness being arranged across the grain of
the other thickness.
In some cases I fit an india rubber ring band or the like, around the edge of
the float to avoid shock against the inside of the can.
The hinge is made so that when the float is opened out flat resting on the milk
or fluid there will be no tendency for it to fold up, but it will rather be kept flat
by the surface of the fluid to which it adheres.
The use of my improved float for milk cans has the following advantages:
1. The float will prevent the slopping of milk during conveyance or delivery
from house to house.
2. It allows free escape of steam arising from the milk which will then "keep"
longer.
3. It prevents the oscillating and churning during conveyance which at pre-
sent prevents the formation of a large percentage of cream which otherwise would
be obtained.
4. This float or disc will rise or fall to the highest or lowest level of the milk.
5. The milk can be drawn off by tap, or measure ladle or dipper down to the
dregs with no inconvenience.

page_text: 6. The float is self adjustable and can be made to fit either round oval or
octagon cans of their respective sizes.

An Improvement applicable to Cans, Bottles, Jars, and the like for
the Conveyance of Milk and other Liquids.
I, JOHN BYWATER, of 130, Castle Street, Edgeley, Stockport, in the County of
Chester, Joiner, 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 following statement:
1
This invention relates to cans, bottles, jars, or similar vessels containing milk
or other fluids, the object being to provide such cans or vessels with an appliance
whereby splashing or waste by spilling the contents is avoided without the neces-
sity for special lids or other expensive devices.
The nature of my said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference
to the sheet of drawings hereunto annexed, and the following explanation thereof.
The drawing illustrates my invention as applied to an ordinary milk can.
Fig. 1 being a vertical section of the can containing milk or other fluid with my
improved appliance shown as applied thereto. Fig. 2 an edge view, and Fig. 3
a plan view of one form of my invention detached. Figs. 4 and 5 similar views
of a modification thereof, and Fig. 6 a horizontal section of a can of milk with
the same inserted therein.
The invention consists of a float a made to fit the inside of the can or vessel b
(which may be of any suitable vertical-sided form) and at the same time to rise
or descend freely in the said can or vessel; this float is made of two pieces hinged
together at c so that it can be folded for insertion through the somewhat con-
tracted mouth of the can or vessel (as shown in dotted lines at Fig. 1) or for allow-
ing the can or vessel to be more completely emptied; it is also made with an
opening or a series of openings d (as shown at Fig. 3) to allow any steam or
vapor arising from the milk or fluid, when warm, to rise and escape through a
suitable ventilator or opening in the lid of the can. For cans from which the
milk or fluid is to be withdrawn by a dipper, or ladle, the opening is a large
one in the centre of the float (as shown at Figs. 5 and 6) which is then in the
form of a ring or the like when floating on the milk or fluid, through which the
largest dipper or ladle can be inserted.
The float and its hinges may be made of any suitable material not injuriously
affected by, or affecting the milk or fluid. I prefer to make the float of wood in
two thicknesses, the grain of one thickness being arranged to cross the grain of
the other thickness.
In some cases I fit an india rubber ring band, or the like around the edge of
the float as shown at e to avoid shock against the inside of the can.
The hinge is made so that when the float is opened out flat resting on the milk
or fluid there will be no tendency for it to fold up, but it will rather be kept
flat by the surface of the fluid to which it adheres.
The use of my improved float for milk cans has the following advantages.

page_text: 1. The float will prevent the slopping of the milk during conveyance or delivery
from house to house.
2. It allows free escape of steam arising from the milk which will then keep
longer.
3. It prevents the oscillating and churning during conveyance, which at pre-
sent prevents the formation of a large percentage of cream which otherwise would
be obtained.
4. This float or disc will rise or fall to the highest or lowest level of the milk.
5. The milk can be drawn off by tap, or measure ladle, or dipper, down to the
dregs with no inconvenience.
6. The float is self-adjustable and can be made to fit either round, oval, or
octagon cans and of their respective sizes.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
The manufacture and use for the purposes specified of a folding float or appli-
ance made with an opening or openings, substantially as hereinbefore described
and illustrated by the drawings annexed.
