COMPLETE SPECIFICATION.
Improved Regulator for Infants' Feeding Bottles.
I PERCY WHITTEN of No. 5 Foster Road, Bruce Grove, Tottenham in the
County of Middlesex, Grocer, 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 relates to an improved means of regulating the flow of milk or
other fluid nourishment passing through the tube of infants' feeding bottles, the
object of same being to furnish an efficient regulator and at the same time one
that will not cut or in any way injure the tube itself; as is frequently the case
with the regulators heretofore in use.
According to my invention I insert a soft cushion of indiarubber, felt, leather
or other suitable yielding material, in the regulator in such a manner that the
regulator may be screwed up to any desired extent without injury to the feeding
bottle tube.
My invention can be more clearly understood by reference to the accompanying
drawings in which Figs. 3, 4, 5 & 6 represent four different modifications of my
invention. I form my regulator in each case by cutting or stamping from sheet
brass, tin or other suitable metal a piece of the requisite size & shape, which is
afterward bent up into the required form.
&
In Fig. 1 a represents an ordinary screw stopper of a feeding bottle having
flanged head 6 to which the regulator is fitted. The regulator in this case consists
of a metal box or shell c in the formation of which; four arms or lugs c¹ are
struck out, thus providing a ready means of attaching the shell to the stopper,
being simply bent around the flanges as shewn in Fig. 1.
Fig. 2. represents a plan of the above.
the arms
Inside this box or shell c a loose sliding bar fits & is in contact with an india-
rubber ring c.
By turning the thumb-screw e the movable side or bar can be forced against
the rubber strip, and the compression upon the latter produces a corresponding
amount of compression upon the feeding tube. A similar form of regulator is
shewn in Fig. 3 but the arms serving to secure the same to the stopper are
dispensed with and the device can thus be readily affixed to any part of the
feeding tube.
Figs. 1. 2. & 3 are sufficient to illustrate the main features of my invention, but
as instances of modifications which readily suggest themselves
may refer to
Fig. 4; in this case the metal is bent into a box shape f¹ open at one side & each
end thereof. A strip of indiarubber c³ is placed in the box, one end of the india-
rubber being clamped at f by the metal as shewn.
The other end of the strip of indiarubber is also clamped in a similar manner f",
by a U shaped strip of metal f' which is placed in the box above the indiarubber.
is a thumb screw which screws in one side of the box & passes loosely through
the upper arm of the U shaped strip of metal while the end of the screw bears.
upon the lower arm of the same piece of metal & by this arrangement the arm
and the rubber strip can be forced down until the feeding bottle tube; which
runs between the indiarubber jaws; is compressed to the extent desired.
In Fig. 5, two pieces of sheet metal g & g' are used which are bent as shewn in
the fig. & then hinged at g'; an indiarubber strip or ring c³ is placed inside and
the thumb-screw e is made to produce the desired compression. In the modification
shewn in Fig. 6, the rubber strip is contained between the arms of a bent
spring h; the latter being enclosed between a rectangular frame h³, through one

page_text: side of which the screw e is passed which bears upon one arm of the spring &
compressing or releasing the same as the case may require.
Having now particularly described and ascertained the nature of my said inven-
tion, I do hereby declare that what I claim is ;
First. In a regulator for infants' feeding bottles, the interposition; between the
feeding tube and the compression screw or plate of a strip or packing of india-
rubber or other flexible or yielding material in the manner substantially as described
& illustrated in the accompanying drawings.
Second: The mode of permanently clamping or affixing the said regulator
to the stopper; substantially as described and illustrated in the accompanying
drawing.
