Year: 1884

page_text: I THOMAS HOWELL WILLIAMS of 125 Fortess Road Kentish Town in the
County of Middlesex Chemist and Mineral Water Manufacturer do hereby declare
the nature of my Invention for IMPROVED APPARATUS FOR AND MEANS OF CLOSING
BOTTLES JARS AND OTHER RECEPTACLES to be as follows:-
The object of my invention is an improved method of and apparatus for closing
bottles jars and other receptacles which require an airtight or gas-tight stopping.
It consists chiefly in the adaptation of what may be called the principle of the
bayonet catch in combination with the principlo of the screw to the necks or upper
portions of bottles jars and other receptacles and to the caps to fit over them.
In carrying my invention into effect I form the top of the bottle jar or other
receptacle with or without the usual rim as may be inost convenient On this rim
or on the neck or upper part of the bottle jar or other receptacle I make one two
or more projections or lugs (preferably two).
I form a cap or cover for the bottle jar or other receptacle of metal glass or other
convenient material or combination of materials of such a size and shape as to fit
over the top of the bottle jar or other receptacle In the wall or rim of such cap or
cover 1 form slits grooves or recesses or combinations of two or more of them to
correspond with the projection or lug projections or lugs already described made on
the rin neck or upper portion of the bottle jar or other receptaclo. These slits
grooves or recesses or.combinations of two or more of them are so shaped as to
allow the cap or cover on being pressed down on the bottle jar or other receptacle
to be tightened by a turn the portion of the slit groove or recess or combination of
two or more of them into which each projection or lug enters when the cap or.
cover is turned being shaped in the form of a segment of a screw for that purpose..
The cap or cover is lined with cork caoutchouc or other suitable elastic material
which when pressed down upon the top of the bottle jar or other receptacle by the
action above described forms an air- and gas-tight joint with the top of such
bottle jar or other receptacle.

I, THOMAS HOWELL WILLIAMS of No 125 Fortess Road Kentish Town in the
county of Middlesex Chemist and Mineral Water Manufacturer do hereby declare
the nature of my invention for IMPROVED APPARATUS FOR AND METHOD OF
CLOSING BOTTLES JARS AND OTHER RECEPTACLES and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement :—
The object of my invention is an improved means of closing bottles jars and
other receptacles which require an air or gas tight stopping. It consists in the
adaptation of what may be called the principle of the bayonet cutch in com-
bination with the principle of the screw to the necks of bottles jars or other
receptacles and to caps to fit over them so as to render the perfect closing of the
bottles or other receptacles more certain and efficient in operation and cheaper in
construction than those at present in use.
In carrying my invention into effect I form the neck of the bottle jar or other
receptacle with or without the usual enlargement on the upper end towards its
exterior part which will be hereafter spoken of as the rim.
On this rim or in the absence thereof on the neck of the bottle or other
receptacle on opposite sides thereof and preferably at right angles thereto I form
two projections or lugs at a distance of 3/8ths or half of an inch from the top of
the neck and preferably equidistant from the top.
The object of these projections or lugs is to form a shoulder or bearing for
holding the cap hereafter described.
I also make a cap to fit over the top of the bottle or other receptacle of metal
glass or other convenient material or combination of materials of such a size as to
fit conveniently over the same.
In the cylindrical portion or wall of this cap in positions and of a size and shapo
to correspond with the projections or lugs on the rim or neck of the bottle or other
receptacle 1 form two recesses or slits or combinations of recesses and slits coin-
mencing from the bottom which I will call the galleries.
I prefer that at the commencement thereof these galleries should traverse the
said cylindrical part or wall of the cap for the first 1/8ths of an inch or thereabouts
in a vertical direction but this is not essential.
From the top of this portion of the gallery the same is continued for a distance
of or 3/8ths of the periphery of the cylindrical part or wall of the cap or there-
abouts in the shape of a segment of a screw the trend of the screw being in an
upward direction.
It is equally efficacious for the purpose of my invention that the gallery as to its
vertical part should consist of a recess and as to the screw portion of a slit or vice
versa and where the cap is of sufficiently solid material the gallery may be formed
entirely of a slit but where the material is weak I prefer to form the gallery
entirely by means of a recess.

page_text: To a person looking at the cap placed in position on the bottle and having the
vertical portions of one of the galleries facing him the screw portion of the same
gallery is on his right hand.
The object of these galleries is to bear up against the shoulder formed by the
two projections or lugs above referred to. When the cap is fitted on the projections
or lugs pass up through the vertical portions of the gallery and when the cap is
slightly turned or screwed the screw portion of the galleries receives such pro-
jections or lugs and the cap is by this means fastened or keyed firmly upon the
neck of the bottle or other receptacle.
In the interior of the cap at the top is placed a disc of cork caoutchouc or other
elastic material sufficiently large to fill or nearly fill the top of the cap.
The effect of this disc of elastic material is that when the cap is placed on the
bottle so that the projections or lugs above referred to can travel along the screw
portions of the galleries then as the cap is turned or screwed the elastic material is
gradually compressed and the mouth of the bottle thereby closed and rendered gas
and air tight.
In the accompanying drawings explaining my invention Figures 1 and 2 are
side views of a bottle neck constructed according to my invention Figure 2 is
another view of same Figure 3 is a view of the top of the bottle Figure 4 is a
view of the top of the cap shown in Figure 5. Figure 5 is a view of a bottle cap
constructed according to my invention having the vertical portion of the gallery
consisting of a recess and the screw portion of a slit. Figuro 6 is a view of a like
bottle cap where the vertical portion of the gallery consists of a slit and the screw
portion of a recess. Figure 7 is a top view of the last mentioned cap Figures 8
and 9 are respectively a perspective view and section of a like cap where the gallery
consists wholly of a slit the latter view showing the lining of elastic material at the
top of the cap Figure 10 is a perspective view of a like cap where the gallery
consists wholly of a recess a is the neck of the bottle bb are the two projections
or lugs cc the vertical portions of the galleries d d the screw portions thereof,
aud fis the packing of elastic material with which the top of the cap is fitted.
I bave described this bottle and prefer the bottle neck to be formed with two
lugs or projections and the cap with corresponding galleries but I may use more
than that number in cases where it may be found convenient to do so.
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
The construction and use of a cap lined at the top with elastic material and
having galleries formed therein in the manner above described such galleries being
partly formed in the shape of segments of screws parallell or practically parallell to
one another in combination with a bottle having lugs or projections on its neck
corresponding to the positions of the vertical portions of the galleries in the cap so
that the bottle may be rendered gas and air tight in the manner and for the
purpose above described and as shown in the accompanying drawings.
