JOSEPH CHALLENDER of No. 15 Cannon Street Manchester Ilumber do nereby
declare the nature of this invention to be as follows:-
My invention consists in a new mode of connecting India rubber pipes (or pipes
made of soft metal, gutta percha or other suitable material) to unions and also for
connecting two or more such pipes together.
At present this object is attained (in so far as India rubber is concerned) by using
a piece of wire wrapped round the end of the pipe to attach it to the tail piece of the
union whereas by means of my invention the pipe is connected in the following
manner.
The apparatus employed for connecting the pipe consists of a union having on its
outside in the thickest part a screw thread over which is screwed a loose piece
consisting of a cap or nut threaded with an inside screw to correspond with the screw
thread on the outside of the union. The union terminates at the end (which is to
receive the India rubber pipe) in a tapering tail piece having on its outer surface a
broad flat screw. Over this tail piece the India rubber pipe is forced by gentle
pressure and screwing action until the pipe is forced as far as it can go when it will
meet with the thickest part of the union before described on the outside of which is
the screw thread for receiving the cap before mentioned.
The loose cap is now passed over the India rubber pipe, or it may be slipped over
the pipe before the latter is attached to the tapering end or tail piece of the union.
The cap is then pushed over the pipe up to the union until it meets the screw and is
then screwed up tight.
This loose cap is provided at the outer end (and inside) with a flange projecting
inwardly which prevents it passing quite over the screw on the union. When
therefore the india rubber pipe is over the tapering tail piece and the cap is screwed
up on to the union the flange presses upon the india rubber pipe and forces it tightly
to the union so that it is locked perfectly tight & cannot be withdrawn.
By using a double union with tapering tail piece at each end & 2 loose caps or
nuts the ends of 2 pieces of india rubber pipe may thus be firmly locked together.
The loose cap or nut is provided with lugs or may be melted outside or made square
to receive a key. Of course the half union may be attached in the usual manner to
a tap or metal pipe. By means of my invention any person may without any tools
attach an india rubber pipe to a union or connect 2 broken pieces of pipe together.

page_text: I JOSEPH CHALLENDER Sanitary Engineer 15 Cannon Street Manchester do hereby
declaro 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 person to join two soft metal pipes
together especially Hose pipe without solder or other flux or composition and also
without the use of wire, string, or of Plyers in the use thereof.
Fig. 1. Shews a screwed hollow body A A made of Brass or other suitable metal
with a shoulder B B and a tapering end CC which is screwed with a broad flat
thread to receive hose or other soft metal pipes.
Fig. 2. Shows a Hallow Brass Cap D D screwed inside with a similar thread to fit
body A A Fig. 1. At one end and inside of this Hallow Brass Cap is a projection or
Flange EE which is made to fit shoulder B B Fig. 1 when screwed up to it.
The outside of Cap D D is milled or shaped to be convenient for hand screwing.
Fig. 3. Shews the union in half section with Hose or soft metal pipes attached F F
being body of union described by letters A B C in Fig. 1. and G G being cap
described in Fig. 2. H. H. representing Hose or soft metal pipes.
.
Fig. 4. Represents the union for attachment to bibs of Water Cocks, Pipes, or
Valves, the part I being made to fasten by solder or otherwise to the end of a pipe,
bib of Water cock or Valve. The body J being described in Fig. 1. A B C, and the.
cap D, as in Fig. 2.
The mode of applying or making this joint is as follows-
The Hose or soft metal pipe is placed over the end of Taper Screw Fig. 1 and then
pushed or turned round, thereby causing the flat taper screw to draw up and hold fast
the hose or soft metal pipe end H Fig. 3, up to the shoulder B. Fig. 1 while the Cap
Fig. 2. (having previously been slipped over end of pipe about to be joined to union
Fig. 1) is screwed to body A A Fig. 1, and by screwing on Cap Fig. 2. until the
Flange E E Fig. 2 is pressed tightly towards the shoulder B Fig. 1. The Hose or
soft metal pipe being between Flange of Cap E E Fig. 2. and shoulder B of Fig. 1. is
thus held secure and a perfect water tight or other joint securely made.
Having thus particularly described and ascertained the nature of this my said
Invention together with the best methods with which I am acquainted for carrying
the same into practical effect, I wish it to be understood I do not confine myself to

page_text: the precise details, proportions or measurements of the various parts of the improved
apparatus hereinbefore described and illustrated on the accompanying Drawing as the
same may be considerably varied without departing from the invention or the
principle thereof. What I do claim is―
1st. The use and application of a flat taper screw on body of the union for holding
fast the hose or other soft metal pipes without slipping and a flanged cap for use in
connection therewith substantially as hereinafter described and illustrated on the
accompanying Drawing.
JOSEPH CHALLENDER.
