Improvements in and in the Manufacture of Regulators for Infants'
Feeding Bottles.
I, AARON SMITH CARTWRIGHT, of Ford Street, Hockley, in the City of Birming-
ham, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
This invention has relation to regulators or attachments to the tubes of infants
feeding bottles, by which the bore of such tubes is contracted to regulate the
flow or passage of the food therethrough.
Ordinary feeding bottle regulators consist of a small rectangular frame or
sleeve with an opening through the side to admit of the same being passed onto
a food tube, and fitted with a screw having an enlarged inner end adapted to
bear upon the tube and compress the same to diminish the size of the same in-
ternally. Such screws, when forced home, are apt to twist and cut the tube by
reason of the inner end rotating with the body of the screw and upon the material
(usually india-rubber) of the tube.
To obviate this objection, I propose to provide the impingement end of the
screw with a swivelling or loose end, in the form of a small metal cap or equiva-
lent, which is first shaped out of sheet metal in a cup figure and then the mouth
of it contracted around the inner end of the screw, which may either be slightly.
enlarged, or provided with a neck or the like into which the metal may be
gathered. Or any other form of loose or swivelling end may be fitted which
bears or impinges onto the rubber and transmits the pressure of the propelling
screw, but without rotating or twisting the tube.
The body of the regulator may be in the form of a short open ended sleeve
and a portion of the metal surrounding the hole through which the screw passes
may be raised into a cavity sufficient to receive the inner end of the screw, which
thus comes flush with the bore of the tube when the screw is fully withdrawn,
and leaves a clear passage wherethrough the tube may be readily introduced from
one end.
To cheapen the cost of producing this form of regulator, I may make the same
by taking a rectangular metal blank of a length equalling that of the article
to be produced and of a width equalling or about equalling its circumference
and after piercing and threading the screw hole and forming a suitable sinking
to receive the inner end of the screw, I fashion the same into a tubular figure
with the joint running along the bottom or along one side as the case may be.

page_text: Improvements in and in the Manufacture of Regulators for Infants'
Feeding Bottles.
I, AARON SMITH CARTWRIGHT, of Ford Street, Hockley, in the City of Birming-
ham, 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 has relation to regulators, or attachments for the tubes of infants
feeding bottles, by which the bore of such tubes is contracted to regulate the
flow or passage of the food therethrough.
Ordinary feeding bottle regulators consist of a small rectangular frame or
sleeve with an opening through the side to admit of the same being passed onto
à food tube, and fitted with a screw having an enlarged inner end adapted to
bear upon the tube and compress the same to diminish the internal size thereof.
Such screws, when forced home, are apt to twist and cut the tube, and also to
wear the material, by reason of the inner end rotating with the body of the screw
and upon the material (usually india-rubber) of the tube.
To obviate this objection, I propose to provide the impingement end of the
screw with a swivelling or loose end, in the form of a small metal cap or equiva-
lent, which is first shaped out of sheet metal in a cup figure and then the mouth
of it contracted around the inner end of the screw, which may either be slightly
enlarged, or provided with a neck or the like into which the metal may be
gathered.
Figure 1 of the accompanying drawing represents an elevation of improved
regulator, applied to the tube of a feeding bottle, and Figure 2 is a longitudinal
section of Figure 1, showing how the bore of the tube is reduced by means of
the swivel-ended regulating screw.
Figure 3 represents a transverse section of Figure upon the dotted line a.
Figure 4 is an end view of the regulator, with the tube being shown in section
and in the act of being introduced edgewise (after being stretched) into the said
regulator through the open slot or gap in one side of the body part thereof.
Figure 5 represents a longitudinal section of the regulator device separately
and upon the dotted line ¹, Figure 4.
Figure 6 is a plan of the underside of the regulator, showing the open-ended
slot or gap in same by which the device is applied to the tube of a feeding
bottle.
The same letters of reference indicate corresponding parts in the several
figures of the drawing.
is the body of the regulator, which is in the form of a short open-ended
sleeve and has a longitudinal gap or slot b, along the whole length of one side,
through which the tube c of a feeding bottle is passed edge-wise as represented
in Figure 4, so that when in use the regulator encircles the said tube as repre-
sented in Figures 1, 2, and 3. d is the regulator screw, working through a
wormed hole a¹, in the side of the regulator, whilst e is the loose or swivelling
cap, which is fitted to the necked or shouldered impingement end d', of the
said screw and is adapted to transmit the regulating pressure to the tube without
at the same time communicating any rotatory or twisting movement, thus
obviating any tendency to cut, wear away, or otherwise damage the material of
the said tube.
A portion of the metal surrounding the hole a¹ through which the screw,
passes may be raised into a cavity or recess f, sufficiently deep to receive the

page_text: swivelling end of the screw, which thus comes flush with the bore of the tube,
when the screw is fully withdrawn, and leaves a clear passage either to admit of
the tube being readily introduced from one end in regulators having no slot or
gap for this purpose, or to ensure the unimpeded passage of food through the
full bore of the tube when required.
To reduce the cost of producing this form of regulator, I may make the body
part of the same from sheet metal by taking a rectangular metal blank, such as
is represented in plan in Figure 7, of a length equalling that of the article to be
produced and of a width equalling or about equalling its circumference and
after piercing and threading the screw hole and forming a suitable sinking
to constitute the recess f for the reception of the inner end of the screw,
fashion the same into a tubular figure with the joint running along the bottom
or, if required, along one side thereof.
Instead of employing a closed-on sheet metal cap to form the swivelling
impingement end of the regulating screw as described and represented, any
other form of loose or swivelling end may be fitted which bears or impinges onto
the tube and transmits the pressure of the propelling screw, but without rotat-
ing or twisting the rubber or other material thereof.
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:
First In regulators for infants feeding bottles, the employment of an
adjusting screw having a swivelly-connected impingement-end" which remains
stationary when the screw is rotated, substantially as and for the purpose herein
described and also as set forth in the accompanying drawing.
Secondly: In regulators for infants feeding bottles, providing in one side of
the body part, a sinking or recess for the reception of the impingement-end of
the adjusting screw, substantially as and for the purpose herein described, and
also as set forth in the accompanying drawing.
Thirdly-In feeding-bottle regulators having a tubular body part, with a
recess for the reception of the impingement end of the adjusting screw on one
side making the same from a blank of sheet metal, substantially as and for
the purpose herein described.
