I THOMAS HOWELL WILLIAMS of No 125, Fortess Road Kentish Town in the
county of Middlesex Chemist and Mineral Water Manufacturer do hereby declaro
the nature of my Invention for IMPROVED MEANS OF AND APPARATUS FOR 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 air or gastight stopping. It
conists chiefly in the adaptation of what may be called the principle of the
bayonet catch in combination with the principle of the screw to the necks 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 a rim as usual In this rim I make two or more depressions or
slots (preferably two) placed at equal distances from one another as nearly as
possible and I form the bottom of the rim in the shape of the segments of screws
starting from the bottom of one edge of the one slot or depression and ending at or
at some convenient distance from the bottom of the near edge of the next slot or
depression. 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 as to
fit over the top of the bottle jar or other receptacle. On the lower part or rim of
such cap or cover I form projections to correspond with the depressions or slots
already described made in the rim of the bottle jar or other receptacle so that these
projections passing through the depressions fit under the rim of the bottle jar or
other receptacle and hold the cap when turned. These projections are also formed
to correspond with the pitch of the scrow form given to the bottom of the rim so
that when the cap is pressed down and turned, the projections travel along the
screws of the rim bottom and the cap thus becomes firmly secured to the top of
the bottle, jar or other receptacle The inside of the top of the cap 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 will form
an air or gastight joint with the top of such bottle jar or other receptacle.

page_text: I, THOMAS HOWELL WILLIAMS of N° 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 MEANS OF AND APPARATUS FOR 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 method of and apparatus for closing
bottles jars and other receptacles which require an air 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 principle of the screw to the necks of
bottles and other receptacles and the caps to fit over them so as to render the
perfect closing of such bottles and 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 and other
receptacle with an enlargement on the upper end around its exterior part as usual
which will be hereafter referred to as the rim.
In this rim are made two depressions or grooves extending from the top of the
rim to the bottom on opposite sides thereof preferably in a direction perpendicular
to the top of the rim.
The rim is divided by these grooves practically into two portions and the lower
edge of each of these portions is utilized for holding two projections from the
interior side of the cylindrical portion of the cap hereafter referred to.
Each of these two portions of the rim which I will call shoulders is shaped in the
form of a portion or segment of a screw of a length of about 3/8th or a little more
of a whole circumference of the bottle neck or rin. These segments of screw
commence from the lower extremity of one side of one groove or depression and
pass round to or nearly to the bottom of the lower extremity of the nearer side of
the opposite groove or depression the trend of the screw being in a downward
direction.
To a person looking directly at either of the said grooves or depressions in the
rim the shorter side of the groove or depression forming the commencement of the
segment or portion of screw is on his left hand.
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 inaterials of such size as to fit
conveniently over the rim thereof.
Towards the bottom of the cylindrical portion or wall of this cap in positions
and of a size and shape to correspond with the grooves or depressions in the rim
of the bottle or other receptaclo I form two small projections or lugs of metal or
other suitable material standing out on the interior side of the cylindrical part or
wall of the cap preferably at right angles thereto.
The object of these projections is to bear up against the shoulders formed by the
lower part of the rim above referred to. When the cap is fitted on the projections

page_text: or lugs pass down through the said grooves or depressions and when the cap is
slightly turned or screwed the projections or lugs travel round through 3/8ths of a
circle or thereabouts and thus fasten or key the said cap 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
suitable elastic material sufficiently largo 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 travel along the portions or
segments of screws above mentioned 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 drawing Figures 1 and 2 are respectively front and side
views of a bottle neck while Figures 3 and 4 are sections of a bottle cap constructed
according to my invention Figure 5 is a top view of the bottle neck shewing the
depressions or grooves in the rim Figure 6 is another view of the cap shewing the
projection or lug formed by means of an indentation in the cylindrical wall or part
of the cap
a is the rim bb the grooves or depressions cc the segments of screws
formed upon the lower sides of the two portions of the rim d d are the projections
or lugs formed on the inner side of the cylindrical part of the cap and fis the
packing of elastic material with which the top of the cap is fitted.
I have described this bottle and prefer the bottle neck to be formed with two
grooves and corresponding screw segments and the top with two projections but
may use more than that number in cases whero it is 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 with the projections or lugs formed therein
and lined at the top with elastic material in combination with a bottle having its
rim formed with grooves or depressions at equal or nearly equal distances thereon
and having the lower edges or shoulders of the portions thereof into which it is
divided by the said grooves or depressions formed into segments of screws parallell
or practically parallell to each other so that the bottle may be closed and rondered
air and gas tight in the manner and for the purpose above described and as shewn
in the accompanying drawings.
