page_text: We, WILLIAM HARRISON, Mechanical Engineer, of 196, Padgate Lane, and
FREDERICK JOYNSON, Chemical Engineer, of Heatherlea, Penketh, both of
Warrington, in the County of Lancaster, do hereby declare the nature of this inven-
tion to be as follows:-
Our invention relates to improved means for making hermetic closures for jars,
bottles and other receptacles such as are used for preserved provisions and so
forth, the object being to provide a closure which shall be airtight and can be with
equal facility applied to the receptacle, removed from same whenever the
contents are required, and afterwards reapplied if desired, no part being injured
and therefore capable of re-use.
According to our invention we form about the mouth of the jar or receptacle
a cylindrical portion of suitable depth having at its base a seat for an elastic
washer and at diametrically opposite points in its sides a pair of L-shaped or
bayonet joint slots recessed into the glass or material of the receptacle, and the
vertical or approximately vertical part of these extends to the top of the cylindrical
part and is open thereat. To fit into the said cylindrical part we provide a closure
or stopper between which and the seat above referred to is placed an elastic washer.
The stopper is recessed at its upper side to two depths of different diameters or has
an internal stop piece for a purpose hereinafter referred to, and at diametrically
opposite points in the upper part of its sides is formed a pair of holes. For fixing
the stopper we provide a cross bar or lever which may be made of steel wire or the
like, and about the middle part thereof is formed an operating handle or projecting
lever, the two ends of which are bent or formed eccentric or out of line with the bar.
The length of the cross bar is such as to pass through the two holes in the sides of
the cover and into the bayonet-joint slots above referred to. The lever handle is of
just sufficient length when the cross bar is in position to lie within the larger recess
of the cover and to rest upon the ledge formed therein by the recess of smaller
diameter, or an equivalent stop piece. In use the stopper is placed in the
cylindrical part of the receptacle, the washer intervening between the two, and
the ends of the cross bar passing down through the open upper ends of the
L-shaped slots. The stopper is then turned by the cross bar so as to bring the
eccentric ends of the latter into and against the ends of the horizontal or practically
horizontal parts of the L-shaped slots. The lever handle is then pressed down to
rest upon the said ledge or stop within the stopper and this action serves by means
of the pressure exerted by the lifting of the eccentric ends of the cross bar to
compress the washer strongly between its seatings and the closure is complete,
the ledge or stop preventing further turning down of the lever. To remove the
stopper it is only necessary to raise the handle of the cross bar, thereby relieving

the vertical parts of the slots when the stopper may be removed bodily.

Improvements in Hermetic Closures for Jars, Bottles, and the like.
We, WILLIAM HARRISON, Mechanical Engineer, of 196, Padgate Lane, and
FREDERICK JOYNSON, Chemical Engineer, of Heatherlea, Penketh, both of
Warrington, in the County of Lancaster, do hereby declare the nature of this inven-
tion, 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 improved means for making hermetic closures for jars,
bottles, and other receptacles, such as are used for preserved provisions and so
forth, the object being to provide a closure or stopper which shall be airtight,
and can with equal facility. be applied to the receptacle, removed from same when-
ever the contents are required, and afterwards reapplied if desired, no parts being
injured by the operations, and therefore capable of re-use.
In fully describing our invention we will refer to the accompanying drawings,
in which Fig. 1 is a sectional view of the upper part of a jar. Fig. 2 is a similar
view of the stopper provided with means for fixing same and making an air-tight
closure. Fig. 3 is a plan of the jar with the stopper fitted thereinto. Fig. 4 is
a view of the locking and operating lever. Fig. 5 is a plan of a jar and cover
showing a slightly modified construction, and Figs. 6 and 7 are sectional elevations
on lines X-X and Y-Y respectively of Fig. 5.
According to our invention we form about the mouth of the jar or receptacle A,
a cylindrical neck a of suitable depth having at its base a seat a¹ for an elastic
washer W, shown in Fig. 2 encircling the stopper C, and at diametrically opposite
points in its side are formed a reversed pair of L-shaped or bayonet-joint slots B B;
these slots are recessed into the glass or material of the receptacle A, and the
vertical or approximately vertical parts 66 thereof extend to the top of the cylin-
drical part a, and are open thereat. The other part 1 of each slot may be
horizontal or inclined slightly upwards as shown in Fig. 1. To fit into the said
cylindrical part a we provide a special cover or stopper C between which and the
seat a¹ above referred to is placed an elastic washer W. The stopper is usually
provided with a top flange f for covering and protecting the mouth of the jar,
and it is recessed on its upper side to two depths c c¹ of different diameters, or
alternatively an internal stop piece may be substituted, for a purpose hereinafter
referred to; at diametrically opposite points in the upper part of the sides of the
stopper a pair of holes hh is provided; or equivalently as shown in Figs. 5, 6 and 7
a pair of opposite slots SS may be substituted, of sufficient length and depth to
correspond when in proper position, with the slots BB in the neck of the jar.
For fixing the stopper in position we use a cross-bar L shown separately in Fig. 4,
made of steel-wire or the like, and about the middle part thereof is formed, by
bending or otherwise, a projecting operating handle 1; the two ends ¹¹ of the
cross-bar are bent or formed so as to be eccentric or out of line with the bar itself,
and when holes h are used, collars such as 12 are provided near the ends 11 of
the cross-bar L for preventing same from falling out and becoming detached
from the stopper when removed from the jar; the length of the cross-bar is such

page_text: as to enable its ends to be passed through the two holes hh or the slots SS in the
sides of the cover and to extend into the bayonet-joint slots BB in the neck of the
jar. The handle / is of just sufficient length when the cross-bar is in the locked
position to lie within the larger recess c of the cover C and to rest upon the ledge
formed therein by the recess of smaller diameter c, as shown in Figs. 2 and 3;
or equivalently a short raised stop piece may be provided in the proper position
instead of a complete circle for preventing undue downward rotary movement
of the locking bar. In use the cross-bar being adjusted, the stopper C is placed in
the cylindrical neck a of the receptacle A, the washer W being intervened between
the two, then the ends of the cross-bar L are passed down through the open-
ended vertical parts bb of the L-shaped slots BB. If holes are used, the
stopper C is then rotated backwards by the cross-bar L sufficiently to bring the
eccentric ends of the latter into and against the ends of the horizontal or
practically horizontal parts b₁ b₁ of the L-shaped slots B. If slots are used
then the cross-bar only is rotated to effect the same result. The lever handle is
finally pressed down until it rests upon the said ledge or short stop within the
stopper, and then lies flush with the top of same; this action serves by reason of
the pressure against the slots 6' 61 exerted by the uplifting of the eccentric ends l¹ l'
of the cross-bar to compress the washer W strongly between its seatings, the ledge
or stop preventing further turning down of the lever and thus the closure is
complete. To remove the stopper it is only necessary to raise the handle 7 of
the cross-bar L, thereby relieving the pressure, and to rotate the stopper (or the
cross-bar alone as above described) forwardly until the ends of the cross-bar
again coincide with the vertical parts bb of the L-shaped slots BB, when the
stopper C may be removed bodily.
By the use of our above described improvement, great facility and security in
hermetically closing and opening jars, bottles, and the like is attained, while at
the same time the operating parts are in no way liable to injury and are therefore
capable of frequent re-use, an advantage which is not to be found with hermetic
jar closures as generally hitherto made.
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 :-
1. An hermetic closure for jars, bottles, and the like, comprising in combination
a cylindrical neck formed on the receptacle having opposite L-shaped slots and a
washer-seating at its base, a stopper recessed in its upper part and with opposite
holes or slots in its sides, a washer intervened between seating and stopper, and
a part rotary cross-bar with eccentric ends and a hand-operating lever, all con-
structed and adapted to co-operate substantially in the manner herein set forth.
2. The improved means for hermetically closing jars, bottles, and the like,
substantially as above described and illustrated in the accompanying drawings.
