Improvements in the Construction of Certain Parts Used in
Connexion with Infants' Feeding Bottles.
I ALEXANDER RICHMOND STOCKER of 76 Glengall Road London S.E. Manu-
facturer do hereby declare the nature of this invention to be as follows:-
My improvements consist in a new arrangement or construction of the parts of
the Fittings used in connexion with Infants Feeding Bottles technically known as
Shields & unions in such manner as to increase durability and to prevent the possi-
bility of the Teat Shield and India Rubber Tube which passes through the cap or
Stopper of the Bottle becoming detached in actual use by the infant which frequently
occurs with the ordinary fittings now in general use and my object is attained in the
following manner.
I form on one side of the ordinary shield which is composed of Bone Ivory
Earthenware or other suitable material or materials (Earthenware by preference) a
hollow projection or collar of the desired outside diameter length and thickness
having a screw thread formed therein extending nearly as far as the round plain hole
which passes through the shield such hole being small enough to prevent the Teat
being completely pulled through in consequence of that part of the Teat called the
"Roll" being of sufficient size to render it impossible when the Teat is inserted in
the hollow screwd projection or collar. The hollow screwd projection or collar may
be turned or moulded in one piece with the Shield or they may be made seperately
and afterwards attached in any convenient manner.
I use and employ with Shields so constructed a hollow nipple or connecting piece
composed of Metal Bone Ivory or Earthenware (the latter by preference) or suitable
material having a screw thread formed thereon to correspond with the screw formed
in the hollow projection or collar of the Shield-through the centre of this hollow
screwd nipple or connecting piece I make a circular hole just large enough to admit
of the passing of the ordinary India Rubber Tube and in the end so passed through
is inserted a short piece of piping of suitable length made of the material or materials
as before described of slightly larger external diameter than the internal diameter of
the Tube which prevents the Tube from being pulled completely through the screwd

page_text: nipple or connecting piece. The Teat having now been passed partially through the
hollow screwd projection or collar of the Shield the "Roll" being larger than the
plain hole therein will prevent its being pulled completely through the screwd
nipple or connecting piece with the India rubber Tube as before explained is now
screwd into the hollow screwd projection or collar of the Shield so that the India
Rubber Tube containing the short picco of hollow piping before referd to partially
enters the Roll of the Teat thereby making an airtight joint at that part at the same
time rendering it impossible to seperate the Teat Shield & India rubber suction Tube
without first unscrewing the nipple or connecting piece from the hollow screwd
projection or collar.
The various parts being screw together as before described may easily be parted
thus allowing for cleansing.-In some instances the screwd projection or collar may
be screwd externally instead of internally & the nipple or connecting piece in that
case would be screwd internally to correspond with it.
In some instances if desired the India rubber Tube containing the short piece of
hollow piping may be passed into the screwd projection or collar from the face of tho
shield in that case the screwd projection or collar would require to have a projection
at the end to prevent its completely passing through a loose screwd collar would also
have to be used in connexion with the Teat to secure it in its place in the screwd
projection or collar from the face of the shield.

Connexion with Infants' Feeding Bottles.
I, ALEXANDER RICHMOND STOCKER, of 76 Glengall Road, Peckham, in the County
of Surrey, 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 :-
My invention relates to certain of the fittings used in connexion with infants'
feeding bottles, and consists in a new arrangement and construction of the parts of
the fittings technically known as shields and unions, whereby an increased durability
is obtained, and the possibility of detachment, while in use by the infant, of the teat
and shield from the india-rubber suction tube, is prevented.
With the ordinary fittings of infants' feeding bottles now in general use this
detachment of the teat and shield frequently occurs, and is a source of continual
danger. To obviate this, in accordance with this my invention, a convenient manner
of constructing the shields and unions is as hereinafter described.
And in order that the invention may be fully understood, and readily carried into
effect, reference is had to the accompanying drawings of which Figure 1 is a view of
the teat, with shield and union, constructed in accordance with this invention, attached
to india rubber suction tube ready for use.
Figure 2 shews in longitudinal section the various parts, detached, of the fittings
to which this invention refers, and Figure 3 is a sectional elevation of the whole fitted
together.
I form on one side of the ordinary shield a, composed of bone, ivory, earthenware,
or other suitable material or materials (earthenware by preference) a hollow projection
or collar of desired outside diameter, length, and-thickness. This projection or
collar I form with an internal screw thread extending nearly the full length of the
aperture through the shield. This aperture is made small enough to prevent the
enlarged part c (called the roll) of the teat d being pulled through the shield.
The hollow screwed projection or collar 6 may be turned or moulded in one piece
with the shield a, or it may be made separately and afterwards attached in any
convenient manner.
With the shields constructed as above described I employ a hollow nipple or
connecting piece e, made of any suitable material such as bone, ivory, or earthenware,
preferably the latter, having a screw thread formed thereon to correspond with the
screw formed in the collar b of the shield. The ordinary india rubber suction tube f
passes through the aperture of this hollow connecting piece e, and in the end so
passed through is inserted a short piece of piping g made of either of the above
mentioned materials. The external diameter of this piece of piping g I make slightly
greater than the internal diameter of the india rubber suction tube.
This prevents
the tube, when stretched upon it, from being completely pulled through the screwed
nipple or connecting piece e.

page_text: For use I attach the above described parts as follows:-I pass the teat d through
the hollow projection or collar till the "roll" or enlarged part c is pressed against
the shield this roll prevents the teat being passed completely through the shield-
I then pass through the hollow nipple or connecting piece e one end of the india
rubber suction tube, in which I insert the short piece of piping g above referred to,
after which screw the connecting piece e into the collar b and in so doing the free
end of the short piece of piping g enters the roll c of the teat, thereby forming an air
tight joint at that part, and at the same time rendering it impossible to separate the
teat, shield, and india rubber suction tube without first unscrewing the nipple e from
the collar b.
It is obvious that the screwed projection or collar 6 may, if preferred, be screwed
externally instead of internally, the nipple or connecting piece e in that case being
screwed internally to correspond with same. And the short piece of piping g may if
desired be formed in one with the nipple e; it may also be formed to protrude through
the back of the nipple e and the india rubber suction tube placed thereon without first
passing through said nipple.
Again, in lieu of the two parts-the shield and the nipple-being screwed together,
any other suitable means of attachment may be employed, such as for instance the
bayonet joint as shewn in Figures 4 and 5. Figure 4 being a back view of shield a
grooved or hollowed out to hold the tongue pieces X Y of loose collar e Figure 5.
Z Figure 4 is a stop pin against which the tongue piece x may rest after the nipple is
attached to the shield.
In some instances if desired the india rubber suction tube containing the short
piece of hollow piping may be passed into the screwed collar b from the face of the
shield. In that case the screwed collar would have to be formed with an internal
flange (See Figure 6) at back to prevent its completely passing through, a loose
screwed nipple i would also be used in connection with the teat to secure it in its
place in shield.
Having now particularly described and ascertained the nature of this invention,
and in what manner the same is to be performed 1 declare that what I claim is :-
In Infants' feeding bottles the shield, in which is inserted the teat, constructed with
a projection or collar, or formed with a groove or recess, to which is attached by
screwing, by a bayonet joint, or by other suitable means, a loose nipple or connecting
piece bearing the end of suction tube, substantially as, and for the purposes hereinbefore
set forth and described.
