COMPLETE SPECIFICATION.
Improved Means for Sealing the Mouths of Glass Jars and the like.
I, WILLIAM HALEY, of 55, Warren Street, Savile Town, Dewsbury, in the
County of York, Glassworks Manager, 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:-
This invention relates to improved means for hermetically sealing the mouths
of jars and the like made of glass, pottery ware or any other suitable material
and in which a readily removable lid or cap is required, the object being to
provide a metal cap with a glass lining containing a groove for the reception of
a suitable jointing material.
The invention will be thoroughly understood from the accompanying draw-
ings in which,
Fig. 1 is a section of a jar fitted with my improved cap and
Figs. 2 to 4 detail views of said caps.
In carrying out my invention I first take a piece of tin B or other suitable
material and press it into the shape of a lid or cover. Then I make a glass
lining to fit neatly in same and compress the outside of lid or cover to the
glass lining, the lining being a little larger on its outer edge. On the face of
glass lining I press a recess or cavity to hold a ring of cork or rubber, the same
being put in tightly and made secure by adding glue or other substance to face
of cork or rubber ring before it is pressed into the cavity; this will cause the lid
or cover and glass lining and ring of cork or rubber to become one lid or cover.
In Fig. 1, A represents a glass jar in section and fully illustrates the different
parts of the lid when fixed in position on the neck of the jar, B is the external
metal cover and is shown as it appears after having been fastened by pressure
on the outer side of the internal glass liner and C is the said liner which is
slightly bevelled or tapered on its outer edge so that it is smaller in diameter at
point & in comparison with the diameter at point H. I do not, however, confine
myself entirely to this method of securing the liner but may use a groove, flat,
or recess of any kind into which the side of cover B can be pressed or fixed. D
is the recess or cavity which is pressed into ring C whilst being moulded and
holds a washer W of suitable flexible material for the purpose of hermetically
sealing the mouth of the jar. E is the threaded or inclined point of the cover B
which is made to fit suitably on a similar thread or incline F formed on the
surface of the neck of the bottle or jar. For this purpose I do not restrict
myself to any particular length of incline or number of threads.
Figs. 2, 3 and 4 are separate views of the metal cap B and glass liner C,
Fig. 4 being a plan of the underside of the liner at J which is at this point
prolonged beyond the face of the flexible washer so as to form a guide or steady
when fixing the lid upon the jar. Fig. 3 is a side view of the liner and Fig. 2
a sectional view of the metal cap previous to the insertion of the glass liner.
The bevel on the latter is somewhat exaggerated for the purpose of distinction.
The cap is shown straight as it is previous to the insertion of the liner and
before being finally pressed to the secure position as shown in Fig. 1.

page_text: The operation of fixing the lid is simply accomplished by inserting the central
projecting portion into the neck of the vessel to be sealed and by a slight twist
the threads or inclines interlock and the face of the flexible washer is pressed
upon the end surface of the vessel's mouth at K thus forming a practically air
or liquid tight joint.
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:
1. In a self contained cap or cover for jars and the like, the combination of
an outer metal cover provided with threads or inclines to engage with similar
threads or inclines on the vessel to be sealed, with a glass liner permanently
secured to said metal cover and grooved to hold a ring of flexible jointing
material to bear on the top edge of the-vessel to be sealed, substantially as and
for the purpose described.
2. A cap or cover for jars and the like constructed and arranged substantially
in the manner described and as shown in the accompanying drawings.
