Improvements in Covers for Jars and similar Wide-mouthed Vessels
and in the Means of Securing the same.
I, FRANK HAZEN PALMER, of 244, Plymouth Street, Brooklyn, in the County
of Kings, and State of New York, United States of America, Manufacturer, dc
hereby declare the nature of this invention to be as follows:-
This invention relates to the covers of jars, cans, and such like wide-mouthed
vessels, and to the means of securing the same, the object of the invention being to
provide a cover and fastener which is simple and durable in construction, securely
holds the cover in place on the mouth of the jar or can, prevents displacement of
the packing, and can be readily opened when desired, without spoiling the fasteners
thus permitting of re-using the device.
The jar or can is provided with an externally-shouldered rim or mouth adapted
to be closed by a cap or cover of cupped form having projecting outwardly from its
circumferential portion or side a flange adapted to hold on its under side a packing
which bears on a seat formed around the mouth of the jar. The packing is secured
to the flange of the cover by bending the outer edge of said flange around the
outer edge of the packing the inner edge of the packing being similarly fastened to
the cover if desired by doubling back the circumferential portion or sides of the
cupped cap or cover on itself, before forming the external flange so as to leave a
rim projecting below said flange, then bending outwards and upwards this pro-
jecting rim so as to make it bear against the under side of the packing near its
inner edge, a groove or recess being formed within the seating on the jar to
accomodate this bent-up rim so that only the middle part of the packing is in
contact with the seat. In the top of the cap or cover are formed two cross-grooves
deepening from the centre to the circumference. In one of these cross-grooves
lies a bail which bears on the centre part of the cover, the bail being bent down-
ward and engaging in notches formed in the horizontal flange of the cover, and the
ends being first bent outward where they enter vertical slots formed diametrically
opposite each other in the flange or shoulder around the seat on the mouth or neck,
the ends of the bail being then bent downward to pass around and then inwards to
form lugs which engage beneath the said flange or shoulder on the mouth or neck
of the jar, the downwardly-extending portions of the bail being quite clear of the
flange or shoulder on the jar so as to permit of inserting a knife or other instrument
between the said part and the flange to unfasten the cover.
When the cover is disengaged from the jar, the packing is held firmly in place
on the cover so that when the latter is placed over the mouth or neck of the jar or
can the said packing readily seats itself, the bail before being fastened having its
inwardly-projecting end lugs resting in the upper and deeper ends of the vertical
alots so that by pressing the ends of the said bail the lugs may be moved downward
in the slots and finally made to snap under the flange or shoulder, thus securely
locking the cover on to the mouth of the jar or can. When the cover is thus
locked on the jar, a displacement or turning of the cover on the neck of the jar is
impossible as the bends of the bail engage the notches of the cover and the upper
ends of the grooves or slots in the flange or shoulder of the jar. By the pressure
exerted by the bail on the cover, the packing is well seated thereby preventing any
leakage and closing the jar air-tight.

Improvements in Covers-for Jars and similar Wide-mouthed Vessels,
and in the Means of Seouring the same.
I, FRANK HAZEN PALMER of 244, Plymouth Street, Brooklyn, in the County
of Kings and State of New York, United States of America, Manufacturer, 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:—
This invention relates to the covers of jars, cans, and such like wide-mouthed
vessels, and to the means of securing the same, the object of the invention being to
provide a cover and fastener which is simple and durable in construction, securely
holds the cover in place on the mouth of the jar or can, prevents displacement of
the packing, and can be readily opened when desired without spoiling the fasteners,
thus permitting of re-using the device.
The invention consists of certain parts and details and combinations of the same
as will be hereinafter fully described and then pointed out in the claims.
Reference is to be had to the accompanying drawings, forming a part of this
Specification, in which similar letters of reference indicate corresponding parts in
all the figures.
Figure 1 is a plan view of the improvement.
Figure 2 is an inverted plan view of the cover with the packing in place and
part in section.
Figure 3 is a sectional side elevation of the improvement on the line x-x of
Figure 1.
and
Figure 4 is a transverse section of the same on the line y-y of Figure 1.
Figure 5 is an enlarged sectional side elevation of part of the improvement,
Figure 6 is a like view of a modified form of the same.
The jar or can A is provided with the neck or mouth B adapted to be closed by
a cover C provided in its centre with a raised portion D formed with diametrically-
extending grooves D¹ and D' pressed into the said raised portion and having their
bottoms inclined downwardly and outwardly as is plainly illustrated in Figures 3
and 4 the groove D¹ being formed at the junction of the grooves D' and D' with
a straight part D, and the lower or outer ends of the said grooves terminating at
a downwardly-extending annular flange D* passing loosely over the neck or
mouth B of the vessel as is plainly illustrated in Figures 3, 4, 5, and 6. From this
vertical flange D extends outward, a horizontal and annular flange De on the
under side of which is held the packing ring E made of paper or other suitable
material and resting with its under side on an annular projection B' formed on the
outside of the neck or mouth B. The packing ring E is secured to the cover C by
bending the outer part of the horizontal flange De downward and inward under
the packing ring E near its outer edge, as is plainly shown in Figures 4 and 6.
This doubled-up part D' of the flange D is outside of the annular projection B',
so as not to touch the latter. If desired, the inner edge of the packing ring E
may be fastened on to the cover by doubling-up the lower part of the vertical
flange D as is plainly shown at D in Figure 6. This doubled-up part D³ engages
the under side of the ring E near its inner edge and is received in a recess formed
in the annular projection B' so that only the middle part of the packing ring E
is in contact with the annular flange B' as is plainly illustrated in the said
Figure 6. Through the diametrical groove D' passes a bail F which rests with its
middle part on the straight part D of the cover D, as is plainly shewn in the
drawings. The outer ends of the bail F are bent downward to form the parts F1
which extend through notches D formed in the annular horizontal flange D of
the cover D. The lower ends of the parts F¹ are bent outward as at F' and

page_text: extend into vertical slots B' formed diametrically opposite each other in a second
annular projection B³ formed on the outside of the mouth or neck B directly below
the annular projection B¹. The bent parts F of the bail F are bent downward to
form a straight part F the inner sides of which extend beyond the outer surface
of the annular projection B³ so as to permit of inserting a knife or other instrument
between the said part F and the outer surface of the projection B to unfasten the
cover, as hereinafter more fully described. From the lower ends of the parts F
extend inwardly the lugs F adapted to engage the under side of the annular
projection B so as to lock the cover C on to the neck or mouth B of the can or
jar A. The upper part of each vertical slot B' is somewhat deeper than the lower
part to conform to the bend F and prevent the downwardly extending parts F', F',
and F, from coming in contact with the inner walls of the said vertical slots or
grooves.
The packing ring E being held firmly in place on the inside of the said cover,
when the latter is placed over the mouth or neck of the jar or can A the said
packing ring readily seats itself on the top of the annular projection B'. The
bail F in its normal position extends about horizontally with the lugs F resting
in the upper ends of the slots B' and when it is desired to fasten the cover to the
mouth or neck of the jar B the outer ends of the said bail are pressed so as to
move the lugs F downward in the slots B' to finally snap under the bottom of the
annular flange B thus securely locking the cover C on to the mouth or neck of the
jar or can A. In placing the cover Con to the neck of the jar, it is necessary
that the diametrical groove D¹ containing the bail F as well as the notches D°
should be in line or register with the vertical grooves B' of the annular flange B³
so that the downwardly extending parts of the bail with the lugs F* may engage
in the said grooves.or slots B³. When the cover C is locked on the jar as
described above, the displacement or turning of the cover on the neck of the jar is
rendered impossible, as the downwardly-extending parts F¹ of the bail engage the
notches D' of the cover C and the bent parts F engage the side walls of the
grooves or slots B' of the annular flange B³. By the pressure exerted by
the bail F on the cover C the annular flange De of the said cover becomes firmly
pressed on the packing-ring E so that the latter is well seated on the top of the
annular projection B' thereby preventing any leakage or spilling of the contents of
the jar. The jar is thus rendered perfectly air-tight.
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 jar-cover having an annular depending flange D' and an annular horizontal
flange De projecting outward from the flange D' bent downward and inward at its
periphery to form a packing groove, substantially as set forth.
2. A jar-cover having an annular depending flange D', an annular horizontal
flange D projecting outward from the flange D and bent downward and inward at
its periphery to form a groove to support a packing ring near its outer edge, and
the doubled-up portion D at the juncture of the two said flanges D', D6, to support
the packing near its inner edge, substantially as set forth.
3. A jar cover grooved transversely across its top and formed with the vertical
and horizontal flanges D', D', the periphery of the flange D' being bent downward
and inward to form a groove to receive the outer edge of a packing ring, and
notches D in the outer edge of flange D', substantially as set forth.
4. A jar cover grooved transversely across its top and formed with the vertical
and horizontal flanges D', D, the latter being turned under at its periphery to
form a groove, a flat packing ring under the flange D° and supported at its outer
edge in said groove, the notches D and the fastening F extending through said
groove and having depending ends extending through said notches and turned
inward as at F at their lower ends, substantially as set forth.
5. The combination, with a jar or can provided with two external annular

page_text: projections located one above the other, of a cover adapted to close the mouth of
the jar and formed with an annular flange, a packing ring held on the under side
of the cover flange by a doubled-up edge of the latter, the said ring being arranged
to seat itself on the uppermost of said projections of the jar or can, and a bail
held on the said cover and formed with downward parts or arms and lugs, the said 5
parts extending through grooves in the lowermost projection of the jar or can and
the said lugs being adapted to engage the bottom of the said lowermost projection,
substantially as shown and described.
