AN IMPROVED BALANCE COVER FOR HOT WATER JUGS AND OTHER COVERED VESSELS OF A SIMILAR DESCRIPTION
Year: 1872

page_text: LETTERS PATENT to Charles Toft, of Gravelly Hill, in the County of
Warwick, Modeller, for the Invention of "AN IMPROVED BALANCE
COVER FOR HOT WATER JUGS AND OTHER COVERED VESSELS OF A SIMILAR
DESCRIPTION."
PROVISIONAL SPECIFICATION left by the said Charles Toft at the
Office of the Commissioners of Patents, with his Petition, on the
28th February 1872.
I, CHARLES TOFT, of Gravelly Hill, in the County of Warwick,
Modeller, do hereby declare the nature of the said Invention for "AN
IMPROVED BALANCE COVER FOR HOT WATER JUGS AND OTHER COVERED VESSELS OF A
SIMILAR DESCRIPTION," to be as follows:-
The object of this Invention is to provide a self-acting balance cover
for the vessels referred to in the title of a simple and inexpensive
description, and this I achieve by forming a cover of a size and kind
adapted to the top of the vessel to which it is to be applied, and causing

page_text: the same to be eventy vatanced over the said top or aperture by berg
suspended in opposite sides of the vessel by means of a pin running
across the centre of the lid, and cemented thereto, the two ends or extre-
mities of the said pin constituting together the axis upon which the lid
works.
It will be understood that a suitable recess is formed in each side of
the vessel for the extremities of the said pin to take in, and by pre-
ference these recesses or bearings are made in a slightly oblique direction
towards the lip part of the jug, so that when liquid is poured from the
jug the cover may not fall off.
I also by preference form a small projection or "stop" in the inside
part of the back of the jug (meaning by that the part near to and in a
right line with the handle), the object of which is to prevent the back
part of the lid from rising higher than the top of the jug, and thus the
possibility of the lid falling off when the vessel is used is avoided.
<
The same result may be attained by forming a similar projection or
stop "under the back part of the cover.
My Invention is equally adapted to those vessels which are fitted with
two lips, each being opposite the other, the only difference being that
when applied in this manner the projection or stop before referred to does
not occur, and in its place there is a second lip.

page_text: year of our Lord One thousand eight hundred and seventy-two, in the
thirty-fifth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Charles Toft, Her special
licence that I, the said Charles Toft, my executors, administrators,
and assigns, or such others as I, the said Charles Toft, my executors,
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 IMPROVED
BALANCE COVER FOR HOT WATER JUGS AND OTHER COVERED VESSELS OF A SIMILAR
DESCRIPTION," upon the condition (amongst others) that I, the said Charles
Toft, my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, 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
"

page_text: stop, which is fixed within the jug to prevent the lid from escaping from
its position when the jug is inclined in a backward direction.
When the jug is inclined in a forward direction so as to pour its
contents from the lip, the cover, whose centre of gravity is situate below
the point of suspension, remains in a horizontal position, as shewn in
Fig. 5, and thereby allows the liquid to escape freely. As the jug is
restored to a vertical position the cover, always remaining horizontal,
closes the mouth of the jug, as in Fig. 1.
The stop before mentioned may be either placed opposite to the lip
and above the cover, or upon the same side as the lid and below the
cover, or upon the same side as the lip and below the cover. In either
case it has the same effect as before described.
In Figs. 5, 6, 7, and 8 the pins f, f, are shewn attached to the sides of
the jug instead of the cover, and the slots or recesses i, i, (which are
here shewn heart shaped), are formed in the sides of the cover to fit over
the pins.
In Figs. 9, 10, 11, the cover is suspended by means of two loops k, k,
and a pin from a hinged arm or lever l, which can be raised together
with the cover in order to clean the vessel to which it belongs.
In Figs. 12, 13, 14, the hinged arm / assumes a circular section, and
itself becomes the pin upon which the suspension loops k, k, of the cover
work. In this case the arm / extends across the vessel and rests upon
its opposite side, whereas in Figs. 9, 10, 11, the support for the arm ľ
was obtained entirely upon one side of the vessel.
In Figs. 9, 10, 11, the vessel has one lip only, and the hinged arm
forms the stop for the cover.
In Figs. 12, 13, 14, the vessel has two lips, and therefore requires no
stop, the cover being required to open in either direction at pleasure.
Having now described the nature of my said Invention, and the
manner in which the same is or may be performed, I desire it to be
understood that without limiting myself to the precise details herein
described, as these may be varied or modified without departing from the
nature of my said Invention, what I claim as the Invention to be pro-
tected by the herein-before in part recited Letters Patent is, an improved

page_text: balance cover for jugs and other covered vessels whose centre of gravity
is situate below the point of suspension, and which therefore always
remains in a horizontal position, substantially as herein-before set forth
and described, and shewn in the Drawings hereunto annexed.
In witness whereof, I, the said Charles Toft, have hereunto set my
hand and seal, the Thirtieth day of July, in the year of our Lord
1872.
