PROVISIONAL SPECIFICATION.
An Improved Regulator for Feeding Bottles.
I AARON SMITH CARTWRIGHT, of 75 Ford Street Hockley Birmingham, in the
County of Warwick do hereby declare the nature of my said invention to be as
follows:-
My invention has for its object an improved regulator for feeding bottles by which
I am enabled to exactly regulate the flow of milk or food from a bottle or other vessel
with ease and in such a manner, that the pressure cannot in any way injure the tube,
while there are no projections or sharp corners, which could in any way scratch a
child. My regulator is also easily attachable and cannot when open fall from the tube,
while the tube may be cleaned without the removal of the regulator.
My invention consists of a thin piece of circular tube of springy metal which is
split almost along the whole of its length in four or more places and cut away to form
four or more arms which are made to spring outwards, and are bent round inwards
at their end. The india rubber or other tube of the feeding bottle passes down the
centre of the aforesaid metal tube and a collar which slides upon the metal tube may
be moved along until the rounded ends of the arms of the spring metal tubo are more
or less pressed against the rubber tube thereby compressing it sufficiently to allow
only the required quantity of milk or food to pass through the tube this being
regulated by the distance the collar is forced along the spring arms thus forming an
arrangement, in which a spring clutch is operated by a sliding collar which arrange-
ment is most easy & effective in its working.

COMPLETE SPECIFICATION.
An Improved Regulator for Feeding Bottles.
I AARON SMITH CARTWRIGHT of 75 Ford Street Hockley in the City of
Birmingham, Manufacturer do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
This invention relates to an improved regulator for childrens' feeding bottles, or the
tubes thereof, whereby the quantity of liquid or semi liquid food to be supplied, can
be readily adjusted.
My said invention, consists essentially of radially disposed spring clipping arms,
drawn together, by a slide or its equivalent.
Figure of the accompanying drawing, represents the nipple end, of a length
of feeding bottle tubing, provided with a regulator made according to my invention.
Figure 2 shows the blank, from which the same is formed and figure 3 an edge
view of the said blank.
Figure 4 the blank cupped, while figure 5 is an end view of the same.
Figure 6 shows the ends of the arins of the partially formed regulator figure 4,
turned or rolled inwardly, figure 7 is an edge view of the clip end of the said
regulator figure 6.
Figure 8 is a section of figure 6, while figure 9, is the complete regulator, with slide,
whereby the drawing to, or the opening out of the arms, is regulated.
Figure 10 is a section of figure 9, and figure 11 a plan and side view of slide

page_text: The same letters of reference, indicate the same parts, in the several figures.
a the spring arms of the regulator, the rolled in free ends of the same, c is the
tubular and base end, with outwardly bulged slide stops c², for preventing the with-
drawal of the slide d.
Normally the spring arms, radiate outwardly, so that on the slide being moved
towards their free ends, they become contracted or drawn inwardly upon the flexible
tubing e with nipple e² at its outer end.
The drawing together of the ends, partially chokes or contracts the bore of the tube,
which thereby regulates the flow or admission of liquid or food therethrough.
Instead of the arms being drawn to, or allowed to expand themselves, through the
intervention of a slide, an inside screwed ring, or adjuster may take upon, a screwed
or wormed part, or parts of the regulator; so that adjustment is performed by a
turning movement instead of a sliding one.
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
-
First. A feeding bottle regulator, or a feeding bottle tube regulator, consisting of
embracing swing arms or jaws, controlled by a slide, substantially as set forth.
Secondly. A feeding bottle tube regulator, consisting of rolled, or curved ended
spring arms, operated and controlled by a slide, or by a rotating ring, or adjustor,
substantially as set forth.
-
Thirdly Making feeding bottle tube regulators, from a blank of cut-out sheet
metal, and by the processes, substantially as described and set forth.
