AN IMPROVEMENT IN OR ADDITION TO VESSELS OR RECEPTACLES FOR EDIBLE SUBSTANCES
Year: 1873

page_text: LETTERS PATENT to Henry Aaron Isaacs and Joseph Michael Isaacs,
both of the Firm of M. Isaacs and Sons, of Fenchurch Street, in
the City of London, and Bleak Hill Works, Burslem, in the County
of Stafford, Manufacturers, for the Invention of "AN IMPROVEMENT
PROVISIONAL SPECIFICATION left by the said Henry Aaron Isaacs
and Joseph Michael Isaacs at the Office of the Commissioners of
Patents, with their Petition, on the 4th July 1873.
We, HENRY AARON ISAACS and JOSEPH MICHAEL ISAACS, both of
the Firm of M. Isaacs and Sons, of Fenchurch Street, in the City of
London, and Bleak Hill Works, Burslem, in the County of Stafford,
Manufacturers, do hereby declare the nature of the said Invention for
"AN IMPROVEMENT IN OR ADDITION TO VESSELS OR RECEPTACLES FOR EDIBLE
SUBSTANCES," to be as follows:-
The object of this Invention is to provide a suitable lid or cover for
cups, pots, jars, or other vessels or receptacles for edible substances,

page_text: which lid or cover is easily removeable and readily capable of being
replaced, and which sufficiently protects the contents of the vessel or
receptacle from the atmospheric air, and can also be used as a saucer or
plate for the vessel or receptacle to stand upon, and for receiving
portions of the contents thereof for distribution or consumption.
The Invention is especially useful when applied to jars for the
reception of jams, preserves, and pickles. These have usually been
covered by a skin or bladder, or piece of paper which is most incon-
venient.
According to our Invention a vessel or receptacle is made of any
convenient shape with or without a handle, and the lid or cover is made'
of a rigid material, and of such shape as to correspond with the contour
or configuration of the inner surface of the upper part or edge of the
vessel or receptacle, so that such lid or cover shall when dropped into
the top of the vessel or receptacle fit into the edge thereof so as to cover
and protect the contents. This cover or lid has a flange lip surface or
other provision for resting upon, and it is sufficiently recessed at its
upper surface to serve as a saucer or plate, and also to act as a stand
for the vessel when removed from the top thereof.
We usually manufacture the vessels and their lids or covers of
porcelain, pottery, or similar ceramic material; but we also manufacture
the articles of glass, metals, or other rigid or suitable materials.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Aaron Isaacs and Joseph Michael Isaacs 2
in the Great Seal Patent Office on the 2nd January 1874.

Michael Isaacs, our exccutors, administrators, and assigns, should
at any time agree with, and no others, from time to time and at
all times thereafter during the term therein expressed, should and
lawfully might make, use, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle
of Man, an Invention for "AN IMPROVEMENT IN OR ADDITION TO VESSELS
OR RECEPTACLES FOR EDIBLE SUBSTANCES," upon the condition (amongst
others) that we, the said Henry Aaron Isaacs and Joseph Michael
Isaacs, our executors or administrators, by an instrument in writing
under our or their hands and seals, or under the hand and seal of one of
us or them, should particularly describe and ascertain the nature of the
said Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that we, the said Henry Aaron Isaacs and Joseph
Michael Isaacs, do hereby declare the nature of the said Invention, and
in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement thereof,
reference being had to the accompanying Drawings, and to the letters
and figures marked thereon, that is to say:-
The object of this Invention is to provide a suitable lid or cover for
cups, pots, jars, or other vessels or receptacles for edible substances
which lid or cover is easily removeable and readily capable of being
replaced, and which sufficiently protects the contents of the vessel or
receptacle from the atmospheric air; and can also be used as a saucer
or plate for the vessel or receptacle to stand upon, and for receiving
portions of the contents thereof for distribution or consumption..
The Invention is especially useful when applied to jars for the
3 reception of jams, preserves, and pickles. These have, usually been
covered by a skin or bladder, or piece of paper which is most incon-
venient.

According to our Invention a vessel or receptacle is made of any
convenient shape with or without a handle, and the lid or cover is made
of a rigid material, and of such form as to correspond with the contour
or configuration of the inner surface of the upper part or edge of the
vessel or receptacle, so that such lid or cover shall when dropped into
the top of the vessel or receptacle fit into and upon the edge thereof, so
as to cover and protect the contents. This cover or lid has a flango lip
surface or other provision for resting upon, and it is sufficiently recessed
at its upper surface to serve as a saucer or plate, and also to act as a
stand for the vessel when removed from the top thereof.
We usually manufacture the vessels and their lids or covers of
porcelain, pottery, or similar ceramic material; but we also manufacture
these articles of glass, metals, or other rigid or suitable materials.
We proceed to illustrate, by the aid of the accompanying Drawings,
the mode of carrying the Invention into practical effect.
Figure 1 is an elevation of a cup or vessel A provided with the cover
or lid B constructed according to our improvements; Figure 2 is a
vertical section of the same; Figure 3 is also a vertical section, but in
this Figure the cover B is shewn serving as a stand or as a saucer or
plate.
Figure 4 is an clevation of the cover or saucer B, and Figure 5 is a
plan of the same. This cover or saucer is made very shallow and it has
on the upper edge a flange or lip b. When this saucer lid or plate B.is
placed on the cup A it drops in a little way so as just to fit fairly the
upper edge or portion and close the cup, so as to protect the contents
from the atmosphere and from damp. It fits so fairly as to retain warmth
in a vessel a comparatively long time. For keeping the joint air tight
for certain purposes we sometimes cement a strip of paper round the
junction of the cup and cover. For cup-shaped vessels we prefer to cut
the strip of a curved form by scale, that is to say, as if struck out by
the radius of a circle so that it covers the joint suitably.
Figure 6 is a vertical section of another form of vessel A and cover B.
Of course the forms may be greatly varied provided the general character
of our Invention as herein described be retained.
Having now described the nature of our said Invention and in what
manner the same may be performed, we declare that we claim, the

page_text: construction and employment or application to jars, cups, and other
vessels or receptacles of a removeable lid, cover, or closure made as
described, and capable of being employed as a saucer, plate, or stand,
substantially in the manner and for the purpose herein-before ex-
plained.
In witness whereof, we, the said Henry Aaron Isaacs and Joseph
Michael Isaacs, have hereunto set our hands and seals, this
Twenty-ninth day of December, One thousand eight hundred
and seventy-three.
