COMPLETE SPECIFICATION.
Improvements in Means for Securing Lids upon Jars and the like.
I, GEORGE W. GOMBER, of Conyngham, in the County of Luzerne and State
of Pennsylvania, United States of America, Gentleman, 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: -
The invention set forth in the following specification, illustrated in the accom-
panying drawings, and pointed out in the claims, relates to certain new and useful
improvements in means for securely sealing or locking the lid upon a can, jar,
bottle or the like, the prime object being to provide an absolute reliable seal for
the preservation of the contents of fruit jars or other receptacles.
A further object, among others, is to provide a lid and means for holding the
same in a locked position which can be instantly applied to use and as readily
removed to gain access to the contents.
In the accompanying drawings:
Fig. 1 is a central section of a jar provided with one form of sealing device;
Figs. 2 and 3 show different constructions for the mouth of a jar and the lid or
cap designed to co-operate therewith;
Fig. 4 is a top view of the preferred form of clamp designed to hold the cap or
lid proper in its adjusted_position;
Fig. 5 is a top view of Figure 4 with the housing or guard for the upper section
removed;
Figs. 6 and
are end views of the clamp taken from opposite sides;
Fig. shows another form of top for the jar.
My invention consists in providing a suitable seat upon the top of a jar for the
reception of the usual elastic ring as rubber, or other suitable material, and a cap
having an annular depending edge designed to rest upon said ring and hold the
same in a seat provided therefor, and further, in a clamp designed to engage
the threaded face provided upon the jar by means of which said cap will be forced
downward and there held until a reverse movement of the clamp is effected.
Referring in detail to the several parts of my invention 1 represents the upper
portion of a fruit jar of the usual or any preferred construction, which is provided
with the annular rib 2 entirely encircling the jar at this point and providing the
seat 3 in which is placed a gasket 4 formed of some yielding material, as rubber,
and upon which the lower curved edge 5 of the cap is designed to bear, when
said cap is forced downward in its operative or locked position.
A threaded face 7 is provided upon the upper end of the jar and with said
threads the vertical section 8 of the cap is designed to engage, and by means of
said construction it will be understood that a few rotations of said cap will reliably
lock the same in engagement with the rubber ring or gasket 4, with the result
that a reliable seal will be provided for the jar.
It will be further understood that said cap may be easily removed by a reverse
rotation thereof, when the contents of the jar will be rendered accessible. In the
other views of the drawings I have illustrated another construction which I
provide to employ under the circumstances; in materializing this form of con-

page_text: struction I provide the jar with a series of threads 9 while preferably above said
threads I locate the annular seat 10, which is preferably inclined as illustrated in
Figure 2, said seat being designed to receive a rubber gasket 11.
Designed to co-operate with the rubber gasket 11 thus mounted in position, I
provide the cap 12 and the clamp 13, the latter consisting preferably of wire or
other suitable form of material, so formed that the collar section 14 will be pro-
vided, said collar section being so disposed as indicated in Figures 6 and 7, that
the meeting ends as 15 and 16 upon one side thereof will lie in a different plane
with respect to each other, said differences of disposition being for the purpose of
enabling these parts to rest in a different thread of the section 9, this position being
clearly indicated in Figure 2.
The construction just described for the clamp makes it possible to form the
same at a trifling cost and yet produce a clamp which will reliably perform its
office of holding the cap 12 in position.
It may be further stated as descriptive of the construction of the clamp, that
after the sections 14 are formed in the manner illustrated and described, the ends
are caused to extend upward, providing the sections 17, which at this point, are
preferably covered with the guard or collar 18; after reaching upward a sufficient
height, the wires are then bent at right angles and disposed horizontally and when
at a point over the center of the jar, I prefer to form therein the depending loop
section 19, it being understood that the ends of the wires are to terminate at
different points, as at 20 and 21 in order that they will reinforce each other and
provide means for making the overlapping ends rigid, which rigidity is reinforced
by wrapping the overlapping ends with the guard or collar 22, which is preferably
formed of sheet metal of suitable thickness and character.
In Figure 3 I have illustrated a different form of scat 23 for the rubber gasket
which may be easily and cheaply formed when the jar is made, while below said
seat is a series of threads 24 designed to receive the form of clamp just described,
and by means of which the cap 25 may be securely held in a locked position.
The cap 25 may be provided with a central recess or depression 26 designed to
seat the depending bend 19 formed upon the clamp and thus prevent lateral move-
ment thereof, while being turned downward in its threaded seat 24 or 9, as
indicated.
I claim a special advantage for the construction herein described and shown and
especially for the disposition of the rubber gasket in an inclined manner, as shown
in Figures 1, 2 and 8, inasmuch as it is thought that a more reliable seal will
thereby be provided, since a wedge-like action is effected through the co-operation
of the rim of the cap with the gasket located in said seat.
In the construction shown in Figure 1 a downward movement of the rim of
the cap upon the gasket will cause a bulking or outward bulging of the latter,
thus practically increasing the line of seal and more reliably guarding against
the introduction of air into the interior of the jar. The same is true with respect
to the construction shown in Figure 2.
In Figure 3 it is clear that if the seat 23 and the rim of the cap 25 are perfectly
formed, a thoroughly reliable seal will be provided by bringing the requisite
pressure to bear upon said cap by means of the clamp shown in Figures 4, 5, 6
and 7, or the equivalent thereof, and while I have shown the preferred construc-
tion of the details involved in my improved seal for fruit jars, bottles, or the like,
it will be understood that any simple change may be made in the construction
without departing from the spirit of my invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. A can or jar having an annular flaring recess in its upper part, a flaring lower
rim resting on said gasket whereby when screwed home the cap acts on a con-

page_text: 2. A can or jar having an annular flaring recess in its upper part, said recess
in its lower part terminating in a groove, an elastic cushion or gasket in said
recess, a screw cap having a flaring lower rim resting on the gasket whereby when
screwed home the cap acts on a continually increasing circumference of the gasket,
all arranged as set forth.
3. A wire clamp for jars and the like, composed of a substantially horizontal
top, depending sides separating and each forming a half circle, and means to hold
the wires together, as set forth.
4. A wire clamp, composed of two wires, each forming one-half of the clamp
fitting the spiral threads of a jar, and means to hold the two-part clamp together,
as set forth.
5. A jar having a screw-threaded top, and a shoulder, a gasket resting on the
shoulder, a top having a flange contacting with said gasket, and a wire clamp
fitting the threaded top and means to hold the wires together, as set forth.
6. A jar having a threaded top, a cap covering the same having a central
depression, a wire having a depending part fitting said depression, and the screw-
threaded top, all arranged as set forth.
