IMPROVED MEANS OR APPLIANCES FOR SECURING THE LIDS OR STOPPERS OF EARTHENWARE JARS
Year: 1884

page_text: I, FREDERIC GROSVENOR of Engle Pottery, GO Boden Street, Glasgow, in the
County of Lanark, Potter, do hereby declare the nature of my said Invention
for "IMPROVED MEANS OR APPLIANCES FOR SECURING THE LIDS OR STOPPERS OF
EARTHENWARE JARS;" to be as follows:-
This said Invention is essentially for securing the lids or stoppers fluid tight over
or into the mouths of earthenware or porcelain jars, having their jointing surfaces
either ground or fitted with india-rubber insertion, or equivalent clastic or yielding
material, between the joints or bearing surfaces of the open mouth and lid or
stopper of the jar.
The nature of the improvements consists in forming a strong shallow outer
projecting rin with a groove or check under it round the mouth or neck of the jar;
and having formed and placed over the lid or stopper, a two, three, or four radial
armed swivelling clutch, with downward and inward projecting catches at the
outer end of each arm, which pass down a corresponding number of recesses cut out
of the said rim, or the lid also when that is as large as the rim or top of the jar, so
that when the clutch is turned round the catches enter the groove, and so grip
under the rim, embracing or retaining the lid or stopper between its arms, and the
top or mouth of the jar ; while a single screw pin is so fitted in an eye in the centro
of the arms of the gripper that when screwed up, its inner end or point, presses on
the centre of the lid or stopper and screws it down on the jointing material with
such force on the top flange or mouth of the jar as to make a very secure and
fluid-tight joint not liable to get loose. The arms and the screw may be sunk into
recesses formed for them in the lid or stopper, when this is found better for saving
space or convenience in packing. Instead of the gripper being formed of radial
arms, it may be made in the form of a disc covering the lid or stopper, with two,
three, or more catches at its outer perimeter, kneed down and inwards to enter the
groove and grip under the rim, so that the central screw can tighten up the lid or
stopper in the same manner as with the radial armed screw gripper first described.

page_text: I, FREDERIC GROSVENOR, of Eagle Pottery, 60 Boden Street, Glasgow, in the
county of Lanark, Potter, do hereby declare the nature of my said Invention
for "IMPROVED MEANS OR APPLIANCES FOR SECURING THE LIDS OR STOPPERS OF
EARTHENWARE JARS," 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 to provide means for securing in place the lids or
stoppers of earthenware or porcelain jars, to render them fluid tight.
The accompanying drawings illustrate in sectional elevation figure 1, and plan
figure 2, a jar fitted with the improved stopper securing devices.
The Invention consists in forming a strong shallow outer projecting rim A with
a groove or cliecka under it, round the mouth or neck of the jar; and having
formed and placed over the lid or stopper B a swivelling clutch C formed with
radial arms and with downwardly and inwardly projecting catches c at the outer
end of each arm, which pass down a corresponding number of recesses a cut out of
the said rim, and of the edge of the lid B, so that when the clutch C is turned
round the catches center the groove & and grip under the rim embracing or
retaining the lid or stopper between its arms and the top or mouth of the jar.-
A single screw pin D is fitted in the centre of the arins of the gripper C which
may be formed with a central eye, and be either flat or sunk that when screwed up
its inner end or point presses on the centre of the lid or stopper and screws it down
on the jointing material-E with such force-on-the-top-flange or mouth of the jar as.
to make a very secure and fluid-tight-joint.-
The-arms and the screw may be sunk into recesses-formed-for them in the lid.or
stoppor when this is found better for saving space or convenience in packing.
Instead of the gripper-being-formed-of-radial-arms, it may be-made-in-the-form-of-
a disc covering the lid or stopper with two, three or more catches at its outer
perimeter, such catches being kneed down and bent inwards to enter the groove
and grip under the rim, so that the central screw may tighten up the lid or
stopper.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be perforined, I declare that what
I claim is,―
The improved devices for securing the lids or stoppers of earthenware jars,
substantially as herein described and illustrated.
