page_text: We
GEORGE ARTHUR CUBLEY and JOB PRESTON both of High Street
Sheffield in the County of York Chemists do hereby declare the nature of this
invention to be as follows:-
Our invention relates to improvements in the construction of stoppers for bottles,
jars, and similar receptacles, such stopper being especially adapted for the purpose of
closing infants feeding bottles; the object being to produce a simple, effective, and
cleanly stopper, incapable of being acted upon, or being made foul by milk, or other
liquids.
It consists of a disc or plate of vulcanite or other non-corrosive material suitable
for the purpose, and an elastic self adjusting clip in combination; the opening into
the bottle or other vessel being provided with a neck or ring made flat on its upper
face, and having a groove or reduced neck for the clip of the stopper to clasp.
The disc is made flat upon that portion of its under surface intended to fit upon
the face of the ring or neck of the bottle, but the central portion may be made to
project for the purpose of entering the opening of the bottle, so as to prevent the
stopper being moved laterally either accidentally or otherwise, and becoming
separated from the bottle.
The self adjusting clip is secured to the top side of the disc; it consists of a central
part by which it is fixed to the disc; and two extensible arms or clipping pieces which
slide upon the centre piece, and are drawn together by a suitable spring.
Thus when the stopper is placed in position the disc is held firmly against the flat
edge of the ring or neck before mentioned and closes the opening; the clips or
extensible arms gripping the groove or reduced neck, and preventing the displacement
of the stopper; an extra spring may be used for pressing the disc against the neck.

page_text: We GEORGE ARTHUR CUBLEY and JOB PRESTON, both of High Street Sheffield
in the County of York Chemists 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 :-
Our invention relates to improvements in the construction of stoppers for bottles,
jars, and similar receptacles, such stoppers being well adapted for the purpose of
closing the central opening in infants feeding bottles, the object being to produce an
effective and cleanly stopper, simple in construction, and incapable of being acted
upon, or of becoming foul by milk or the like.
The annexed sheet of drawings will illustrate our invention, and similar letters of
reference will indicate similar parts in any of the figures in which they occur.
Fig. 1, is an elevation of a stopper, half being shown in section.
Fig. 2, represents a plan, and side view of a disc of Vulcanite, or like material.
Fig. 3, represents a plan, and side view of two metallic clips.
Fig. 4, perspective view of metallic slide to hold the clips..
Figs. 5 & 6, two rubber washers or springs.
In constructing a stopper suitable for an infants feeding bottle, and which is shown
in the accompanying sheet of drawings, we use a disc or plate of vulcanite, or of
other non-corrosive material suitable for the purpose, marked A, the said disc or plate
is to be held against the lip or rim B, formed round the opening into the bottle, which
is made flat, and is also provided with a reduced neck.
A short pin C, is secured in the centre of the top side of the disc A, to which the
other parts of the stopper are attached.
A metallic slide D, Fig. 4, having its edges E, turned over, as shown, is put upon
the pin C and rests loosely upon the boss F, which projects from the upper side of
the disc A.
This metallic slide, or guide, receives two metallic clips G, G¹, shown in Fig. 3,
which can be moved to and from the centre of the disc, but are constantly drawn
towards the centre by the contraction of a rubber ring H, Fig. 5, which is passed
over the two pins I, I, or by any other spring applied in like manner.
The rubber washer J, Fig. 6, is placed under the head of the pin C, and acts against
the top side of the slide D, thus holding the various parts in their relative positions
with an elastic pressure.
We prefer to form an annular recess K, on the top side of the disc, to receive the
extreme ends of the pins 1, so that the elastic ring H, or other substituted spring,
cannot climb over the ends of the said pins; we may also if desirable, form on the
face of the disc A, a projection to enter the opening into the bottle, as a further
security against the accidental displacement of the stopper.

page_text: Thus when the stopper is placed in position as shown in Fig. 1. the ends of the
clips G & G which are suitably curved, clasp the neck of the bottle under the lip B,
and the face of the disc A is pressed firmly against the flat edge of the lip B,
by the combined action of the rubber washer J, and the clips.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed, we declare that what we
claim, is:
A stopper for bottles and similar receptacles, constructed substantially in the
manner hereinbefore described and illustrated.
