I, WALTER JONES, trading as Jones and Attwood, of Enville Street, Stourbridge
in the County of Worcester, hot water 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, reference being had
to the accompanying drawings and the letters of reference marked thereon (that is
to say):-
The object of this invention is to simplify and cheapen the construction of a
throttle valve employed in connection with the pipes referred to in the title, and to
combine therewith simple means of connection with the pipes, so that the valve
with its connections or joints may form a valve and simple expansion joint com-
bined, and to economise space occupied by the valve when fixed.
According to the ordinary method of constructing the valve and connecting it
with the pipes the tubular part of the valve is formed of considerable length, and
each end of this tubular part is connected with the adjacent pipe just in the manner
in which one pipe is connected with another, that is to say, a plain metal ring
is placed around the abutting ends of the tubular part of the valve and of the
pipe, respectively, and a packing ring is placed at each end of the plain metal ring,
and a metal socket ring or recessed flange at each end of the joint covers the packing
material, and the two socket rings or recessed flanges of each joint are drawn
together by means of bolts.
Now, according this invention each end of the valve is formed as a short socket,
instead of as a long tubular projection as is usually the case. Each socket is of
sufficient diameter to readily admit the end of a pipe, and the connection is formed
by placing the end of a pipe within each socket, respectively, and with a packing
ring around each pipe and butting against the outer face of each socket, and with
a socket ring or recessed flange around each pipe and covering the packing.
material, and then tightening together the two socket rings or recessed flanges by

page_text: means of bolts. The valve with its connections or joints thus becomes a valve and
simple expansion joint combined.
This invention will be readily understood on reference to the accompanying
drawings, of which figure 1 is a view in elevation on one side of the vertical centre
line, and in longitudinal section on the other side of such line, shewing a valve
constructed, and connected to the pipes, according to this invention. Figure 2 is a
section taken on line of figure 1, and figure 3 a section taken on line y y
of figure 2, shewing one of the bolts connecting the two socket rings or recessed
flanges.
A is the disc forming the baffler or throttle, which is constructed and operated in
the usual manner. "B B are short sockets on the fixed part of the valve. OC are
the ends of the pipes connected with the valve. DĎ are elastic packings, and
E E socket rings or recessed flanges of the character usually employed, and having-
the usual lugs a a for the reception of the bolts b b. The joints are made by
inserting the ends of the pipes C within the sockets B, and tightening up the elastic
packings D D by drawing together the socket rings or recessed flanges E E by
means of the bolts b b.
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
1. A throttle valve constructed with short socket ends, in combination with
means for connecting it to pipes employed in hot water and exhaust or other low
pressure steam heating apparata or employed to conduct the flow of water, steam,
or other fluid at a low pressure, substantially as described.
2. The combination, with a valve constructed with sockets B B, and pipes used
in hot water and exhaust or other low pressure steam heating apparata or used to
conduct the flow of water, steam, or other fluid at a low pressure, of packings D D,
socket rings or recessed flanges E E, and bolts b b, substantially as described and
shewn, for the purpose set forth.
