Improvements in Valves or Cocks for Retaining or Regulating the
Flow of Steam, Hot-water, or other Gases or Liquids.
I, THOMAS FARRAR of Fleece Street, Keighley in the County of York, Brass
Founder and Finisher, do hereby declare the nature of this invention to be as
follows, that is to say :-
It has especial reference to those valves or cocks, for retaining or regulating
the flow of steam, hot-water or other gases or liquids, wherein the valve
part is arranged and constructed to be pressed down upon its seating, which
is formed integrally with the body of said cock, said seating being formed so that
while in use and so long as the surfacing or packing material of the valve will
endure, it tends to improve rather than deteriorate the joining surface of the valve
which is pressed into contact with it, and the object of this invention is to construct
this valve in such a manner that when it is found necessary to repair or renew said
surfacing or packing material on the valve, it may be effected readily and
conveniently.
To attain this object I form the joining surface of the valve, cup-shape or hollow
to receive the surfacing or packing material, and about centrally in this valve I
form a bolt or projecting piece, of any suitable shape in cross section provided this
shape is of such a nature as to prevent the packing material from rotating or
shifting its position. The outer end of this projecting-piece is screwed for the
reception of a nut, so that by the packing substance or material having a central
opening to allow the insertion of said projecting piece or so that it will fit tightly
over same by the tightening up of the nut this packing substance is securely,
although detachably, held in position.
The packing substance is formed in pieces to fill the cup-shaped end of the valve
and by having duplicate pieces of this packing substance only a very limited time
is occupied when renewing.
The packing material may be of any soft metal or other well known substance.

COMPLETE SPECIFICATION.
Improvements in Valves or Cocks for Retaining or Regulating the
Flow of Steam, Hot-water, or other Gases or Liquids.
I, THOMAS FARRAR late of Fleece Street, now of The Borough Brass Works,
Greengate, Keighley in the County of York, Brass Founder and Finisher, 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, that is to say :-
"
It has especial reference to valves or cocks for retaining or regulating
the flow of steam, hot-water or other gases or liquids, wherein the valve
part is arranged and constructed to be pressed down upon its seating which is
formed integrally with the body of said cock, the said seating being constructed or
shaped so that while in use, and so long as the surfacing or packing material of the
valve will endure, it tends to improve rather than deteriorate the joining surfaces
of the valve which is pressed into contact with it; and the object of this invention

page_text: is to construct this valve in such a manner that when it is found necessary to repair
or renew said surfacing or packing material it may be readily and conveniently
effected.
In the accompanying sheet of drawings, which are illustrative of my invention
and to which reference is made in the following description.
Fig. 1 is side elevation of a cock or valve of the kind to which my invention is
applicable.
Fig. 2 is a vertical section of said cock, showing the application of my
improvements.
Fig. 3 is a sectional view showing the valve in detail.
Fig. 4 is a similar view to Fig. 3, showing a modification hereinafter described.
Figs. 5 and 6 are illustrative of the parts shown by Figs. 3 and 4 as seen from
beneath.
Figs. 7, 8 and 9 show in detail the formation of the packing material.
To attain the object of my invention I form the joining surface a on the valve b
of cup-shape or hollow to receive the surfacing or packing material c, and on this
valve b I form a bolt or projecting piece d of any suitable shape (but preferably
square) in cross section in the part d', such part d' being to prevent the packing
material e from rotating or shifting its position in the cup a. The outer end of
this projecting piece d is screwed for the reception of a nut e so that by the packing
material c having a central opening e¹ to allow the insertion of the part d¹ on the
projection piece d (said part d' being made to fill the opening c¹) by the tightening
up of the nut e the material c is securely, although detachably held in position.
As an alternative means or a mechanical equivalent for the square part d', a
square part may be formed on the packing material c and a corresponding
recess 9 made in the valve-cup a to receive this part f, a screw h being screwed into
an opening made in the said valve-cup a to retain the said material c within said
cup a while its square-part prevents same from rotating therein.
These packing pieces c are formed to fill the valve-cup a and by having duplicates
of these said packing-pieces c only a very limited time is occupied when renewing.
The packing material of which the pieces c are formed may be of any soft metal
or other well known substance.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The use and employment of the packing pieces c formed as described in
combination with the valve b substantially as set forth.
2. The combination of a detachable packing-piece formed as specified, with a
valve arranged and constructed to receive same substantially as and for the purpose
described.
