PROVISIONAL SPECIFICATION.
An Improved Regulator or Stopper for Babies' Feeding Bottles and
other Bottles, applicable also for use as a Tap or Cock.
I, ALBERT EDWARD HANCOCK, of 105, Finch Road, Handsworth, in the
County of Stafford, Manufacturer, do hereby declare the nature of this invention
to be as follows:-
This invention consists of the herein described improved regulator or stopper
for babies' feeding bottles and for other bottles my invention being also applic-
able for use as a tap or cock for regulating or controlling the flow of liquids
and gases.
I will first describe my invention as applied for controlling the flow of liquid
through the indiarubber tube of a baby's feeding bottle.
In carrying out my invention I provide a bottle stopper of wood or other
suitable substance through which the indiarubber tube passes and this bottle
stopper is made with a boss at the top through which is a transverse hole the
centre of which is somewhere about in a line with one edge of the usual hole in
the stopper where the indiarubber tube is situated. Adapted to turn in this
transverse hole I provide a plug which may be parallel or taper and which
is cut away at one part to correspond with the hole through which the india-
rubber tube passes. The plug has a head or projection at one end and a side
handle or pin at the other or at both ends for turning the same.
When the
said plug is turned in one direction the cut away part of the plug allows of a
free passage of liquid through the indiarubber tube but when the said plug
is turned in the opposite direction the solid part of the plug coming in contact
with the indiarubber tube squeezes the same tightly against the side of the hole
in which the indiarubber tube fits and thus closes the passage through the tube.
By turning the plug to any intermediate position the passage of the liquid from
the indiarubber tube is more or less constricted as may be required. The plug
is maintained in any intermediate position by the handle or side peg of the plug
fitting against a flat or roughened part formed on the side of the stopper.
It will be evident that the stopper above described with the plug and the india-
rubber tube can be used as a tap or cock for controlling the flow of liquids from
vessels the said stopper part then having a spigot end to drive into the tap hole
or made with a flange or otherwise formed for connection to the vessel or pipe
with which the tap is to be used.
When applying my invention as a bottle stopper for aerated water and other
bottles containing liquids under pressure I may dispense with what I have
described as the stopper and make the plug to fit in a transverse hole formed
in the neck of the bottle itself, the said bottle neck having also a short india-
rubber tube fitting in it which is compressed to close the passage therethrough
by turning the plug as above described.

I, ALBERT EDWARD HANCOCK, of 105, Finch Road, Handsworth, in the
County of Stafford, Manufacturer, 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;-

This invention consists of the herein-described improved regulator or stopper
for babies' feeding bottles and for other bottles, my invention being also applic-
able for use as a tap or cock for regulating or controlling the flow of liquids
and gases.
I
I will first describe my invention as applied for controlling the flow of liquid
through the india-rubber tube of a babies feeding bottle.
In carrying out my invention, I provide a bottle stopper of wood or other
suitable substance, through which the india-rubber tube passes, and this bottle
stopper is made with a boss at the top through which is a transverse hole, the
centre of which is somewhere about in a line with one edge of the usual hole in
the stopper where the india-rubber tube is situated; adapted to turn in this
transverse hole, provide a plug which may be parallel or taper, and which
is cut away at one part to correspond with the hole through which the india-
rubber tube passes. The plug has a head or projection at one end and a side
handle or pin at the other or at both ends, for turning the same. When the
said plug is turned in one direction the solid part of the plug coming in contact
with the india-rubber tube squeezes the same tightly against the side of the
hole in which the india rubber tube fits and thus closes the passage through the
tube. By turning the plug to any intermediate position the passage of the liquid
from the india-rubber tube is more or less constricted as may be required. The
plug is maintained in any intermediate position by the handle or side peg of
the plug fitting against a plate or roughened part formed in the side of the
stopper.
It will be evident that the stopper above described with the plug and the india-
rubber tube can be used as a tap or cock for controlling the flow of liquids from
vessels, the said stopper part then having a spigot end to drive into a tap hole
or made with a flange or otherwise formed for connection to the vessel or pipe
with which the tap is to be used.
In order that my invention may be fully understood and ascertained I append
drawings in which:-
Fig. 1 shews my invention applied to the neck of a feeding bottle.
Fig. 2 is a plan, and
Fig. 3 is a vertical section of same on an enlarged scale.
Figs. 4 and 5 are views of the plug.
Fig. 6 is a section, and
Fig. 7 an end view of my invention as applied to a tap or cock.
A, indicates the body of the stopper which is inserted into the neck of the
bottle, and retained therein by any convenient means, a worm a being here shewn
for that purpose.

page_text: contains the flexible tube B, in such manner that when the plug occupies the
position shewn in Fig. 2, the tube B is fully open, and consequently any liquid
contained in the bottle is free to flow out of the tube B. But when the plug C
is turned by means of the handle c or other device through a quadrant of a
circle the solid part of the plug C compresses the flexible tube B, and prevents
the passage of liquid, thus effectually stopping or closing the bottle. By turning
the plug to a smaller degree than this the flow of liquid without being entirely
stopped may be regulated to any desired extent.
It is obvious that this device may be applied for the purpose of regulating
the flow of liquids into, or out of any kind of bottle or any receptacle, or through
any pipe or tube, and in Figs. 6 and 7 is shewn a device which may be used as
a tap for insertion in a barrel, these figs. are almost self-explanatory, E, forming
the body of the tap, one end being inserted in a hole in the barrel, G the trans-
verse plug, and H the longitudinal flexible tube.
In some cases I make the plug of larger diameter and bore a hole transversely
through the same, the flexible tube passing through this hole it is obvious that
the turning of the plug will effectually close the flexible tube.
When applying my invention as a bottle stopper for aerated water and other
bottles containing liquids under pressure I may dispense with what I have
described as the stopper and make the plug to fit in a transverse hole formed in
the neck of the bottle itself, the said bottle neck having also a short india-
rubber tube fitting in it which is compressed to close the passage made through
by turning the plug as above described.
In some cases instead of forming a groove in the plug, I shape a portion of
the same of square, oblong or irregular section.
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
1. A bottle stopper or regulator in which the flow of liquid is stopped or
regulated by moving a plug in such manner as to close or partially close a
flexible tube through which the liquid flows, substantially as described and
shewn.
2. A cock or tap for controlling the flow of liquids in which the movement of
a plug closes or partly closes the flexible tube through which the liquid flows
substantially as described and shewn.
3. In stoppers or regulators for use in feeding bottles and the like the com-
bination of the stopper A, the longitudinal tube B, and the transverse plug C,
all arranged and operating in such manner that the turning of the plug closes
or partially closes the flexible tube, substantially as described and shewn.
4. In a cock or tap, the combination of the body E, the flexible tube H,
and the plug G, arranged and operating in such manner that the turning of the
plug closes or partially closes the flexible tube, substantially as described and
shewn.
