PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Cones for Water Closets and
the like, commonly called "Closet Cones."
I, SAMUEL THOMAS BASTER of 585 Commercial Road, in the County of
London, Manager, do hereby declare the nature of this invention to be as
follows:-
The invention has for its object improvements in the manufacture of cones for
water closets and the like commonly called "closet cones" and used for the purpose
of connecting the lead water-pipe with the flushing nozzle of a water closet basin
and for other analogous purposes.
"
Heretofore "closet cones" have been made of sheet rubber with a layer or
lining of canvas on the inner side of the "bulb" thereof; this method of
construction is defective as the canvas lining is liable to become detached in use
and the joints of the rubber are liable to burst open. I obviate these difficulties
by the following method of manufacture.
I employ a mould or form of the internal shape of the "closet cone" and I dip
the same in a bath of rubber solution several times until I obtain a sufficient
substance of rubber, I then cement around the bulb portion of the rubber coated
mould or form a strip or strips of canvas after which I again dip the mould or
form with the partially made "closet cone" thereon into the rubber bath until
a sufficient substance is obtained for the finished article; the edges of the
"closet cone" may be left plain or they may be thickened by rolling after which
the article is submitted to the usual vulcanizing process.
By this method of construction I obtain a "closet cone" which is seamless and
therefore not liable to split, in addition to which the canvas strengthener is
embedded between two thicknesses of rubber and therefore protected against
becoming detached.

Improvements in the Manufacture of Cones for Water Closets and
the like, commonly called "Closet Cones."
I, SAMUEL THOMAS BASTER, of 585 Commercial Road, in the County of
London, Manager, 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 invention has for its object improvements in the manufacture of cones for
water closets and the like commonly called "closet cones" and used for the purpose

page_text: of connecting the lead water-pipe with the flushing nozzle of a water closet basin
and for other analogous purposes..
Heretofore closet cones" have been made of sheet rubber with a layer or
lining of canvas on the inner side of the "bulb" thereof; this method of
construction is defective as the canvas lining is liable to become detached in use
and the joints of the rubber are liable to burst open. I obviate these difficulties by
the following method of manufacture.
Two forms of articles made according to my present invention are shown in the
accompanying drawings in which Fig. 1 is an exterior view and Fig. 2 a section
of a "closet cone" in which the axis is in a straight line and Figures 3 and 4 are
like views of a closet cone in which the two ends are at right angles with
each other.
I employ a mould or form of the internal shape of the "closet cone" and I dip
the same in a bath of rubber solution several times until I obtain all over the same
a sufficient substance a of rubber I then cement around the bulb or central
portion of the rubber coated mould or form a strip or strips of canvas b after
which I again dip the mould or form with the partially made "closet cone"
thereon into the rubber bath until a sufficient substance c is obtained for the
finished article the layers a and c forming one solid mass of rubber at the two ends
whilst at the centre or bulb they enclose between them the canvas b.
"
The edges d and e of the "closet cone" may be left plain or they may be
thickened by rolling as shown after which the article is submitted to the usual
vulcanizing process.
By this method of construction I obtain a "closet cone" which is seamless and
therefore not liable to split, in addition to which the canvas strengthener b is
embedded between two thicknesses a and c of rubber and therefore protected
against becoming detached.
It will be evident that the shape of the closet cone may be varied without
departing from the peculiar character of my invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A seamless "closet cone" having a canvas strengtheuer embedded at the bulb
between two thicknesses of rubber substantially as and for the purpose stated.
2. The improved method of manufacturing closet cones, substantially as herein
shown and described.
