I RICHARD WILLIAM HALE of N° 12 Chalton Street Euston Road in the
County of Middlesex Ventilating and Sanitary Engineer do hereby declare the
nature of my said invention for IMPROVEMENTS IN JOINT CONNECTIONS
SANITARY, DRAIN AND OTHER PIPES to be as follows:-.
OF
The object of my Invention is to construct a joint in two or more parts with
collars in such a manner as to render the pipe sound and easily connected or
disconnected-The outside collar of the joint is made in two or more (I prefer two
only) parts with a cavity for the reception of the inside collar which is packed
with asbestos vulcanized Indiarubber or any elastic or other material or substance,
the effect being to make the pipe immediately a sound one and air, or gas tight—
The pipe thus jointed can be readily connected or disconnected at pleasure.

Improvements in Joint Connections of Sanitary, Drain, and
other Pipes.
I RICHARD WILLIAM HALE of N° 12 Chalton Street Euston Road in the
County of Middlesex Ventilating and Sanitary Engineer do hereby declare the
nature of my invention for IMPROVEMENTS IN JOINT CONNECTIONS OF SANITARY
DRAIN AND OTHER PIPES and in what manir the same is to be performed, to be
particularly described and ascertained in an by the following statement :-
1
The object of my Invention is to construct a joint in two or more parts with
collars in such a manner as to render the pipes sound and easily connected or
disconnected-The outside collar of the joint is made in two or more parts (I prefer
two only) with a cavity for the reception of the inside collar which is packed with
asbestos vulcanized Indiarubber or any elastic or other material or substance, the
effect being to make the pipe immediately a sound one and air water or gas
tight The pipe thus jointed can be readily connected or disconnected at pleasure
without disturbing or breaking the joint of any other pipe.
The accompanying drawings illustrate the manner in which I carry my Invention
into effect.
Figure 1 is a horizontal section through the ends of two pipes, packing or inside
collar and the outside collar forming joint connections according to my Invention.
Figure 2 is a vertical cross section say on the line X, Y of Figure 1 of tubes
with joint connection according to my Invention and shewing the said tube
supported in a chair.
Figure 3 is a vertical cross section on line X¹ Y₁ of Figure 1 of the same or
similar tube taken through the inside collar or packing and covering the junction
of the pipes.
Figure 4 is a horizontal section through the ends of two pipes which are shewn
flush with one another as well as through the inside packing collar with a top plan
view of the flanges on the lower outer collar.
Figure 5 is a perspective view of the pipe connection and Figures 6 and 7 are
perspective views of the two inner ends of the pipes shewing how they may be
brought together.
Similar letters of reference refer to like parts in all the Figures.
A A¹ are the two pipes to be jointed together the ends of which may be flush
with one another or of dovetail, zig-zag, V-shaped, or other convenient form or
such for example as the form shewn at Figures 1, 2, 3, 6 and 7 all according to the
class of tube to which the invention is to be applied. BB' are rim bands round these
pipes A A¹ with which the latter are in most cases provided for holding the outside
collars in position while screwing up the joint. CC are the outside collars into
which the rim bands B B fit and DD are the flanges on the collars C, C which
are securely held together by bolts and nuts as best seen at Figures 1, 2, 3 and 5.
The collars are preferably made in two parts and with V or other conveniently
shaped surfaces at the point of junction. E, Figure 3 shews the entrance to the 4
packing or inside collar F which is or may be composed of asbestos, vulcanized

page_text: Taia rubber, lead or any other suitable material or composition which is suitable
for the particular purpose to which the pipe is to be applied whether for example
for the passage of water, gas or sewage. The pipes may be supported on chairs as
shewn at Figure 2 or in any other convenient manner as circumstances may admit.
To couple or join two pipes according to my Invention the two ends of the pipes
A A¹ are laid against or brought together on the lower balf of the outside collar C,
the rin bands B B fitting into corresponding cavities in the said lower half of the
collar C. The top half of collar C is then placed on the lower half thus surrounding
(and when the nuts are screwed up tightly embracing) the ends of the two
pipes A A'. The material for forming the insido collar when to be composed of a
material in a liquid state such as molten lead is then run into the annular cavity F
through the entrance E until full and thus when solidified forming a perfect collar
round the joints the length thereof being determined by the length of the cavity F
or size of the pipes. When the collar is composed of a substance not liquefiable
the same may be put on before the putting the outside collars C C in position and
then the aperture E may be dispensed with. Thus according to my Invention the
pipe joints can be easily fixed and unfixed; in the latter case it
remove the top outside collar and then the inside collar and to lift out one of the
only necessary to
pipes which action is facilitated by making the pipe ends as shewn at Figures 6
and 7 the vertical edges thereof being sloped off or bevilled in contrary directions
to one another while the horizontal edges are V-shaped, and I produce a joint for
pipes suitable for connections of sanitary, drain, water, gas, and other pipes which
8 a perfectly simple rigid and comparatively cheap joint as may be. Junctions
according to my invention may be made of earthenware or iron although I do not
imit myself to such.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
claim is
In pipe joint connections the inner with the outside collar or collars and the pipo
nds together with the means employed for fitting the same and for securing the
arts together all constructed substantially as and for the purposes set forth.
