Improvements in and relating to Pipe Fittings for use in connection
with Heating Apparatus.
GEORGE MORRIS, of Beeston, Nottingham, Heating Engineer, do hereby declare
the nature of this invention to be as follows:
This invention relates to improvements in pipe fittings used in connection with
radiators and similar heating apparatus, and has particular reference to heating
apparatus arranged on the single pipe system, in which system, the water for
a radiator is taken from and returned to the same pipe without interferring with
the passage in such pipe, and in order to obtain a satisfactory How of water
through the radiator, the outlet in the pipe, or flow to the radiator is at the top
of the pipe, and the inlet to the pipe from the radiator, or the return is at the
bottom of the pipe or near thereto.
The object of this invention is the provision of simple and efficient means for
ensuring the desired flow of water through the radiator, and the arrangement of
such means whereby central connections are obtained.
According to this invention the outlet in the pipe to the radiator, called the
The inlet
flow, can be obtained by an ordinary tee piece in the usual manner.
to the pipe from the radiator called the return is obtained by a tee piece having
an opening at or near the bottom of the pipe and a passage from this opening
round the pipe to a socket on the top of the pipe. There may be openings and
passages on both sides of the pipe with connections to the same socket on the
top of the pipe.
For applying this invention to pipes already fixed, the passage to the socket
is formed in a clip which is fastened round the pipe over an opening in the
same.
The tee piece herein referred to may also be used for obtaining a flow from
an overhead pipe.

Improvements in and relating to Pipe Fittings for use in connection
with Heating Apparatus.
GEORGE MORRIS, of Beeston, Nottingham, Heating Engineer, 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:-
This invention relates to improvements in pipe fittings used in connection with

page_text: radiator and other heating apparatus, the said improved fitting being particularly
applicable to heating apparatus arranged on the single pipe system, in which
system, the water for a radiator has to flow from and return to the same pipe
without obstructions in the pipe to the flow of water through the same.
The object of this invention is the construction of a simple and efficient fitting
whereby the desired flow of water through the radiator is obtained, and by which
central connections are obtained.
According to this invention the improved fitting may be in the form of a tee,
elbow, bend or of other convenient shape, and has a full bore passage for the flow
of water through it. At a convenient position on this fitting there is a socket
which is in communication with the interior of the pipe by means of a passage,
which is outside the pipe and opens to the pipe on the side opposite to the socket,
There may be one or more passages from the socket to the pipe and the socket
may be at the top or bottom of the pipe according to the arrangement of the
pipes.
In the drawings which accompanying this specification.
Fig. 1 is a longitudinal section of the improved fitting.
Fig. 2 is a transverse section of an improved fitting with one passage between
the socket and pipe, and
Fig. is a transverse section of an improved fitting with two passages between
the socket and pipe.
In the drawings the fitting is shown in the form of a tee has a body a which
is tapped at both ends for the pipe and has an internal diameter equal to that
of the pipe. On the top of the body there is a socket which is screwed for the
return flow pipe from the radiator and from this socket the water flows to the
interior of the fitting through a passage c which opens into the pipe at the side
opposite to the socket, but without being carried below the bottom of the pipe.
In the fitting shown in Fig. 3 there are two passages & and e which open into
the fitting and socket at opposite sides of the same.
The fitting is usually of the form shown but it may be in the form of a bend
elbow or other shape and may be screwed, tapped or made with flanges or sockets,
and it may be used for the return flow connection when the radiator is above the
pipe, or as a flow connection when the pipe is above the the radiator.
The improved fitting may also be used for a flow or return, for purposes other
than heating, provided the medium used is heavier at the bottom of the pipe
than at the top of the same.
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
I claim is:-
A pipe fitting substantially as herein described with reference to the accom-
panying drawings and for the purpose herein set forth.
Dated this 23rd day of December 1899.
