PROVISIONAL SPECIFICATION.
Attachment for Chamber Utensils.
WILLIAM AUGUSTUS CASSON of 22 Addison Road Bedford Park Chiswick in the
County of Middlesex Gentleman do hereby declare the nature of this invention to
be as follows:
The object of this invention is to provide a detachable non-conducting covering for
the rims of Chamber Utensils so as to avoid the abstraction of heat from that part
of the body which comes in contact with the said rim which in the case of children
causes them pain in cold weather and also a shock to the system.
According to this invention I provide a ring of indiarubber or other suitable
material of U section to fit over the rim of the utensil which ring may be covered
outside with plush or other suitable material the ring being of sufficient width to cover
all portions of the utensil with which the body is liable to come in contact.
The ring is removed before the utensil is emptied of its contents and replaced before
the utensil is used again.

COMPLETE SPECIFICATION.
Attachment for Chamber Utensils.
I WILLIAM AUGUSTUS CASSON of 22 Addison Road Bedford Park Chiswick in the
County of Middlesex Gentleman 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 :-
The object of this invention is to provide a detachable non-conducting covering for.
the rims of chamber utensils so as to avoid the abstraction of heat from that part of
the body which comes in contact with the said rim which in the case of children
causes them great pain in cold weather and also a shock to the system.
According to this invention I provide a ring of indiarubber or other suitable
material of U or other suitable section to fit over the rim of the utensil which ring
may be covered outside with plush or other suitable material the ring being of
sufficient width to cover all portions of the utensil with which the body is liable to
come in contact.
The ring is removed before the utensil is emptied of its contents and replaced
before the utensil is again used.
And in order that my said invention may be the better understood I will proceed to
explain the same with reference to the accompanying sheet of drawings in which
Figure 1 represents a chamber utensil with a ring constructed according to this
invention in position for use.
Figure 2 plan of ring removed from same.
Figures 3 and 4 are sections of ring bereinafter referred to.
The same letters denote the same parts in all the figures.
a is the utensil and 6 the ring constructed of indiarubber or other suitable material
preferably flexible which may be covered with plush or other suitable material on the
outside thereof or instead of making the ring of soft rubber I may make it of
vulcanite and cut it across as shewn in dotted lines at c Figure 2 to allow of it being
expanded laterally to fit the utensil.
The section of ring shewn at Figure 3 is suitable for utensils having a round edge
and the section shewn at Figure 4 is suitable for utensils having flanged rims.

page_text: Although not shewn in the drawing rings constructed according to this invention
may be applied to urinals of the shapes adapted for the use of invalids.
I am aware that patents have been previously taken out for chamber utensils with
a non-conducting material permanently attached to the rims thereof but such utensils
are open to the objection that they cannot be emptied of their contents after use
without soiling the non-conducting material.
I do not therefore claim broadly the use of non-conducting materials in connection
with the rims of chamber utensils but
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
The detachable non-conducting ring adapted to be placed on the rim of a chamber
utensil and removed therefrom substantially as described and shewn for the purpose
specified.
