page_text: I JOSEPH CHALLENDER of No. 15 Cannon Street Manchester Plumber do hereby
declare the nature of this invention to be as follows:-
My invention consists in an improved method of connecting india rubber or other
pipes to a union or tap.
.
I use a metal box or casing tapering at the lower end to a tail piece suitable for
receiving the pipe and at the upper end containing a circular hole or opening to
receive the tap to be connected. The upper end of the box consists of a cap which
screws off and forms the lid of the box.
-
The inside of the box I fill with india rubber having through its centre a hole into
which the nose of the tap is to be thrust. The cap is screwed onto the metal box and
keeps the india rubber fast but does not squeeze it.
A water tight joint is there made by the insertion of a washer of leather or other
suitable material.
When the nose of the tap is inserted into the round hole at the upper end of the box
gentle pressure is used to force the metal box over the nose of the tap-the latter
(being usually of a tapering form of smaller diameter nearer the end), becomes fixed
to the india rubber by friction & tends to press the india outwards thus holding the
metal box tight upon the tap. The pressure is therefore from the inside of the india
rubber & not from the outside as claimed in previous inventions for this purpose.

page_text: 1 JOSEPH CHALLENDER Sanitary Engineer 15 Cannon Street Manchester, 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 enable any one to attach a hose pipe or other
similar pipe to a bib-cock without solder or any screwing operation, or the use of any
tools.
Fig. 1 shews the union B applied to an ordinary bib or water cock E with hose A
or other flexible tube attached to union B.
Fig. 2. shows this union in section, B represents a metal box to hold a rubber
washer or ring F with a tail piece, G to receive hose or other pipe. The cap C. is
screwed to fit on the top of metal box B with a hole D to allow bib of cock H Fig. 1
to be pushed into the rubber ring or washer F, which has been previously inserted into
the metal box B. before screwing on cap C, and by pressing the metal box B
containing rubber ring or washer F on to bib of cock H Fig. 1 you form a perfect
joint by the tapering bib of cock H Fig. 1 swelling the rubber ring or washer F tight
round the bib H Fig. 1. Any back pressure of water pressing on the inside J of
washer or rubber ring F intensifying the grip or hold and thus forming & allowing
a connection to be quickly & easily made.
Fig. 2. will also show that to make this union more applicable to fit the different
sizes of Bib cocks which are presumably and generally sold as one size. I have made
the washer F to stand some distance above edge of metal box B marked X therefore
by screwing down the cap C-(prior to applying the union to bib of cock H Fig. 1) you
will compress the washer F and reduce the hole to smaller dimensions thus enabling
the union to fit the various differences in sizes of Bib cocks.
Fig. 3. section of India Rubber ring or washer shewing inside of hole J through
washer, where Bib of Cock (H Fig. 1) is inserted (and any back pressure of Water
expanding the ring or washer F which expansion being resisted by metal box or
casing B Fig. 2) forms the Joint.
Fig. 4. shews plan of metal box B Fig. 2. D shewing hole in Brass Cap.C: Fig. 2.
J. hole through Rubber washer or ring F Fig. 3.
Fig. 5. shews washer F Fig. 3 in plan J shewing hole through Rubber Ring or
washer.
Having thus particularly described and ascertained the nature of this my said
Invention, together with the best methods of carrying the same into practical effect, I

page_text: wish it to be understood, I do not confine myself to the precise details, measurements,
or dimensions of the various parts of the improved Apparatus herein before described
and illustrated on the accompanying Drawing, as the same may be considerably varied
without departing from the principle of the Invention, or the Invention itself. What
I do claim is―
1st. The use and application of a plain ring or washer made of India Rubber or
other suitable material when properly mounted and applied substantially as for the
purposes described and illustrated in the accompanying Drawing.
2nd. The use and application of the cap being serewed down on the washer until
the size of hole in washer or ring is reduced to fit various sizes of Bib Cooks.
This action to take place previous to attaching the union to Bib of Cock.
