PROVISIONAL SPECIFICATION.
An Improved Valve.
I WILLIAM WILSON HORN of the firm of Horn & Son of 151 Strand in the
County of Middlesex Patent Agent do hereby declare the nature of this invention
(a communication to me from William H. Kelly and John Jenckes both of
Warren, County of Bristol, State of Rhode Island, United States of America
Inventors) to be as follows:-
Much difficulty has heretofore been experienced in providing a stuffing box for a
valve which will not leak, more particularly when the valve is used for superheated
steam, the packing in such case inelting or burning.
This invention has for its object to construct a valve which may be employed for
steam, or any other purpose, but more especially for superheated steam, and yet
have none of the effects above noted.
In accordance with this invention the valve case has a passage through it from
end to end, and also an opening into it at right angles to said passage in which
opening the valve proper or plug is placed. This opening is made tapering and
the valve proper or plug is made correspondingly tapering. The valve proper
which resembles a plug, is made hollow and is closed at that end of smallest
diameter. It has an inlet or inlets near the end of largest diameter, and an outlet
which terminates near the end of smallest diameter, so that the course of the steam
or other material through the valve is in a direction toward the smaller or closed
end of the tapering plug, acting to drive it more firmly into the tapering socket or
opening which receives it.
A suitable plate is employed to close the opening in which the plug is placed and
constituting a closed end for the larger end of the tapering plug.
A packing ring may be inserted between the plug and the said plate.

An Improved Valve.
I WILLIAM WILSON HORN of the firm of Horn & Son of 151 Strand in the
County of Middlesex Patent Agent do hereby declare the nature of this invention
(a communication to me from William H. Kelly and John Jenckes both of Warren
County of Bristol and State of Rhode Island United States of America Inventors)
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This invention has for its object to construct a valve which may be employed for
steam or any other purpose, but more especially for superheated steam and yet have
none of the defects hereinafter noted.
Much difficulty has heretofore been experienced in providing a stuffing box for a
valve which will not leak, more particularly when the valve is used for superheated
steam-the packing in such cases melting or burning.
In accordance with this invention the valve case has a passage through it from
end to end, and also an opening into it at right angles to said passage, in which
opening the valve proper or plug is placed. This opening is made tapering, and
the valve proper or plug is made correspondingly tapering.

page_text: The valve proper, which resembles a plug, is made hollow, and is closed at that
end of smallest diameter. It has an inlet or inlets near the end of largest diameter,
and an outlet which terminates near the end of smallest diameter, so that the course
of the steam or other material through the valve is in a direction toward the
smaller or closed end of the tapering plug acting to drive it more firmly into the
tapering socket or opening which receives it. A suitable plate is employed to close
the opening in which the plug is placed and constituting a closed end for the larger
end of the tapering plug.
Fig. 1 shows in vertical section a valve embodying this invention.
Fig. 2. a left hand side view of the valve proper or plug.
Fig. 3 a right-hand side view of the valve proper or plug.
Figs. 4 and 5 sectional and edge views of the packing ring which may be
employed.
The valve case a has a circular tapering socket formed in it, which receives a
tapering plug a¹ secured to a valve-stem passing through the said case in con-
tinuation of the plug. A hand-wheel a² is secured to the stem d by which it and
the plug a' are rotated. The plug a¹ is made a little shorter than the depth of the
socket, so as to leave a chamber between the smaller end of the plug and the
smaller end of the socket.
This tapering plug a¹ is made hollow, as shown, and
open at its larger end. The plug at one side near its larger end, has one or two
small inlet openings or passages ee and at the opposite side has a larger outlet
opening or passage terminating near the upper end of the plug. The valve
case a has at one end an inlet passage curved or directed downwardly from the
end to the tapering socket, communicating with said socket near its larger end and
at the inlet openings or passages e e. The valve-case a has also an outlet-
passage opposite the inlet passage and curved or directed downwardly from
at or near the smaller end of the tapering socket to the end of the case thereby
communicating with said socket near its upper end and with the outlet passage
of the plug a
e¹
To hold the tapering plug in the valve-case, a plate g is screwed into the socket
which may bear against the larger end of the tapering plug and may be adjusted
in any suitable manner, altho I prefer to interpose a ring between the larger end
of the plug a¹ and the plate g, which ring has transverse or radial openings f¹
through it. The ring and plate g may be formed in one piece if desired.
When
the plug a' is in the position shown to permit the steam to pass through it, the
steam will pass down the declined passage b through the ports or passages e e into
the hollow or chambered plug a' thence through the port or passage and down
the declined passage . It will be seen that the direction the steam takes in the
plug a is upward or toward the smaller closed end of the plug a' and acts to drive
and hold the plug steam tight in the socket.
When the plug is given a quarter turn, the steam will pass down the declined
portion and through the ports passages or holes f¹ in the ring and into the
plug a¹ acting in substantially the same manner as before described.
By this construction it will be seen that the smaller end of the plug snugly fits
the tapering socket at its smaller end, and by the pressure of the steam is held
steam tight; also, it will be seen that no stuffing-box or packing is required the
omission of which, as before stated, is the chief object of this invention.
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. In a valve, a valve-case having a tapering socket and inlet and outlet
passages and a tapering hollow plug in said socket combined with a plate g and
a ring having holes through it interposed between the plate and plug, substantially
as described.
2. In a valve, a valve case having a tapering socket and inlet and outlet

page_text: passages and a tapering hollow plug in said socket having inlet and outlet passages
combined with passages through which communication with the interior of the
plug is continually established, substantially as described.
