A communication from abroad by THE BARNETT BRASS COMPANY, of Mansfield,
County of Richland, State of Ohio, United States of America, Corporation
organized pursuant to the laws of the State of Ohio.
I, WILLIAM PHILLIPS THOMPSON F.C.S. M.I.M.E. of the Agency for Foreign
Patent Solicitors, 6 Lord Street, Liverpool, and 6 Bank Street, Manchester, both in
the County of Lancaster, and 323 High Holborn, in the County of Middlesex, Civil
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 stop valves, and pertains to improvements in means for
attaching the spindles and valves thereof each to the other whereby the valve proper
is permitted to have a rotary motion on the spindle, but can be easily separated
therefrom for replacement or repairs, and the invention consists in the peculiar
construction and arrangement of the attaching mechanism, all as hereinafter fully
described and pointed out in the claim.
In the drawing forming part of this specification,
Figure 1, is a vertical sectional view of the hub of a stop valve, and of a spindle
and a valve having applied thereto devices for attaching the valve to the spindle,
constructed according to this invention.
Figure 2, is a perspective view of the valve.
Figure 3, is a perspective view of an internally screw-threaded nut.
In the drawing, 4, indicates the hub of a valve of ordinary construction having
thereon the usual stuffing-box 5, and internally screw-threaded to receive the
correspondingly threaded valve-spindle, 3. The said valve spindle, 3, has an annular
collar c, formed on its lower end, and above said collar on the screw-threaded part
of the spindle is placed a nut, 7, having a cylindrical neck e thereon, said nut being
adapted to be screwed closely against the upper side of the said collar, c, and to
be screwed away from said collar at pleasure.

page_text: The valve proper, 6, has its under side constructed as usual, that is to say, with an
annular groove therein containing a packing substance of vulcanized material or soft
metal which when forced against the diaphragm of the valve makes a tight joint, but
the upper side of said valve, 6, is peculiarly constructed to adapt the valve to be
attached to the end of the spindle, 3, as below described.
An annular chamber, v, is formed in the top of the valve, 6, having an over-
hanging border, b, and one side of said annular chamber has a passage cut through
it at B, said passage, B, being of sufficient width to allow the collar c, on the end of
the spindle, 3, to pass through said passage into the chamber v, to the position shown
in Figure 1.
The diameter of the opening in the top of the valve within the said over hanging
border, b, is considerably greater than the diameter of the threaded part of the
spindle, 3, and of proper size to admit the neck, e, of the nut into said opening which
is surrounded by said border.
In assembling the above described valve parts in complete relation, as shown
in Figure 1, the nut, 7, placed on the spindle first and then the hub, 4, and its
stuffing box are placed thercon, and then the usual hand-wheel is secured to the upper
end of the spindle. The valve, 6, is then attached to the lower end of the spindle by
placing the collar c, on the latter in the chamber v, of the valve, as above described,
and then the nut, 7, is screwed down against the upper side of said collar to the
position shown in Figure 1. In so screwing down the nut 7, its neck, e, is made
to project into the annular opening within the overhanging border, b, and since the
diameter of the neck e, of the nut is greater than the width of the passage, B, between
the edges of said border, neither the nut nor the spindle can pass laterally between
the sides of said passage, and hence the valve and the spindle are securely attached
one to the other, but in such a way that the valve may turn freely on the end of the
spindle and vice versa, thereby providing for the desired freedom of movement between
said parts with scarcely a possibility of the valve ever becoming accidentally detached
from the spindle. The slight rotation of the valve spindle in the valve when
the latter comes to a bearing on the seat of a stop valve causes a like movement of the
nut, 7, and in fact the rotary movements of the spindle in either direction cause a like
movement of said nut, and as the latter is so fitted into the opening in the top of the
valve that it does not come in contact with the said border, b, no danger exists that
the nut can work loose and permit the valve and spindle to become disconnected by
that means.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me
by my foreign correspondents, I declare that what I claim is :-
The improved spindle and valve connection hereindescribed consisting of the
spindle, 3, externally screw threaded, having the annular collar, c, on its lower end,
combined with the nut 7, having a screw engagement with the spindle above said
collar, and the valve 6, having an annular chamber, v, in one side to receive the lower
end of said spindle and collar, said chamber having an overhanging border, b
surrounding an opening of suitable diameter to receive the neck, e, of said nut, and a
passage through its side of a width less than the diameter of said neck, substantially
as set forth.
