IMPROVEMENTS IN CHAMBER VESSELS
Year: 1872

page_text: COMPLETE SPECIFICATION filed by George Haseltine at the Office
of the Commissioners of Patents, with his Petition and Declamation,
on the 15th August 1872, pursuant to the 9th Section of the Patent
Law Amendment Act, 1852.-A communication from abroad by
Ferdinand Imhorst, of the City and State of New York, United
States of America.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
HASELTINE, of the "International Patent Office," Southampton Build-
ings, London, Doctor of Laws, send greeting.
WHEREAS I am in possession of an Invention for “IMPROVEMENTS IN
CHAMBER VESSELS," and have petitioned Her Majesty to grant unto me,
my executors, administrators, and assigns, Her Royal Letters Patent for
the same, and have made solemn Declaration that it has been com-
municated to me from abroad by Ferdinand Imhorst, of the City and
State of New York, United States of America.
NOW KNOW YE, that I, the said George Haseltine, do hereby declare
that the following Complete Specification, under my hand and seal, fully
describes and ascertains the nature of the said Invention, and in what
manner the same is to be performed, in and by the following statement,
reference being had to the accompanying Drawing forming a part of this
Specification:-

page_text: This Invention consists in the arrangement of an inwardly projecting
flange on the upper edge of a chamber pot in such a manner that when
the vessel is suddenly moved the danger of spilling the contents is
materially diminished, as when the contents reach or splash against
the upper part of the vessel the flange prevents their escaping or
splashing over. The said Invention consists also in forming the chamber
pot, especially at its mouth, of an oval, pear, or egg shape.
Figure 2 is a top view thercof with the cover removed.
Figure 3 illustrates a modification of the said Invention.
Figure 4 illustrates another modification of the same.
A designates a chamber pot which is in this instance made egg-
shaped, but which may be oval or pear-shaped if desired. On the upper
edge of this vessel I have formed an inwardly projecting flange a, and
an outwardly projecting flange b, The flange a I consider of great
advantage in the construction of a chamber pot, as by suddenly moving
the vessel the contents thereof are necessarily agitated and brought out
of position, and thereby have a tendency to splash over the edge. By
forming the said inner flange on the upper edge however this difficulty
is obviated, as the contents if tossed about will strike the said flange and
be arrested and kept from leaving the vessel.
The object of the outwardly projecting flange b is to form in com-
bination with the inwardly projecting flange a a convenient seat which
shall be wide enough to form a good surface to support the body.
That feature of my Invention which consists in forming the chamber
pot of an oval, pear, or egg shape, is advantageous not only by being
better adapted to the human figure and therefore presenting an "casy"
surface to rest upon, but also by obviating the tendency which
characterizes round-mouthed chamber utensils to distend the muscles
of the lower parts of the body and produce the disorder commonly known
as " piles."
Another advantage of this form of mouth in utensils of this description

page_text: as the contents can be better directed and controlled than when the
mouth of the utensil is circular. The inside flange a may terminate
at either or both ends so as to form a good outlet or passage for
emptying the vessel, and in Figures 2 and 3 the flange is thus inter-
rupted or made to vanish at the end opposite the handle c.
Having thus fully described the said Invention as communicated to
me by my foreign correspondent, I claim,—
First. A chamber pot made in an oval, pear, or egg shape, substantially
as described.
Second. The inwardly projecting flange a on the upper edge of a
chamber pot, for the purpose herein specified.
Third. The combination of the flanges a, b, on the upper edge of a
chamber pot to form a widened surface for the body to rest upon, sub-
stantially as described.
In witness whereof, I, the said George Haseltine, have hereunto set
my hand and scal, this Fifteenth day of August, in the year of
our Lord One thousand eight hundred and seventy-two.
Witness,
W. ROBT. LAKE.
