Monmouthshire Brass Founder & Engineer do hereby declare the nature of my
invention for ACCOMMODABLE AND EXPANSIVE VALVES CONSISTING OF VARIOUS
MODES OF CONSTRUCTION, WHEREBY INCREASED SECURITY &C. &C. ARE AFFORDED
to be as follows:-
First. The employment of a bend or Elbow or tee shape-pipe of the necessary or
required area and having the one end made conical to any suitable angle with
outlets in the periphery of the same and the said cone fitted with a thimble or
tapered ferrule lined with Indian-rubber or Leather or any other suitable material,
fitting the said cone, and long enough to embrace the parallel part of the pipe and
straped thereto with a metal bracket & bridle for supporting the lever geared
thereto and used for working the said Ferrule or Thimble in opening and closing
the valve or the same may be fitted with a spring or springs for self closing.
Second. In lieu of using the Indian-rubber, or Leather or any other material,
Tube seating and Ferrule as above described a stuffing box coned at one end to suit
the conical end of the pipe, the other end having the stuffing box made to suit the
parallel part of the pipe and to slide thereon, may be used and the same connected
to a similar lever or links and lever & spring or springs as above-with a horrizontal
valve of Indian-rubber, leather or any other material attached to the cone part of
the pipe and the outlet-branch projecting within the conical part of the stuffing
box which may be in the solid of it or otherwise screwed into it and form the
valve seat which in practice actuating the lever, or its equivalent, the same is
brought to bear, steam or water tight upon the valve and held thereto by a clutch,
a spring or springs or by any other suitable means, in this case the pipe cone
periphery outlets may, or may not, be uncovered at all times.
Thirdly the bore or pipe orifice may be of parallel diameter throughout and the
sliding conical stuffing box having in the cone end a branch discharge pipe within
it as above described but the said pipe projecting further within the said stuffing
box with the orifice at this end closed and covered with leather or other material
to form the valve and in this case to have the outlet holes, of equal passage area,
immediately below that cover into the discharge pipe, which together with the
main pipe outlet forms or constitutes the valve-the stuffing box connected and

page_text: actuated upon as above described for opening and shutting the valve or in lieu
of an horizontal valve or seat a conical valve may be used within the said
stufting box.
Fourthly a tube may be used of necessary length and diameter having one end
open and its outer diameter enclosed in a stuffing box and gland and the other end
closed and in a conical shape, to any suitable angle, having in the same, outlet
holes as before described (for some uses the cone may be fitted or furnished with
leather or Indian-rubber for seating) and this end also to be enclosed in another
stuffing-box containing and acting the valve seat-The said tube or valve fitted
with the necessary spring and geering for working the same and connected some-
where between the two stuffing-boxes-The whole of this arrangement consisting
of two stuffing boxes, geering, and one tube which together constitutes its features
of novelty.
Fifthly a tee shape pipe may be used having a tubular or solid valve as above
described but having one stuffing box-and connected with suitable geer at the
outer or top end or anywhere most suitable-In some cases the conical end groved
and covered or fitted with indian-rubber, leather, or other suitable material.

page_text: I, DAVID PERFITT GRIFFITHS MATTHEWS, of Laburnum House, Cardiff Road,
Newport, Monmouth, Brass Founder and Engineer, do hereby declare the nature of
my invention for "IMPROVEMENTS IN AND CONNECTED WITH CONICAL VALVES,"
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
That the improvements may be clearly understood, I will with the aid of the
accompanying drawings proceed to describe means employed by me.
Fig. 1, shews elevation of an elbow pipe and fittings. A, is the body part
having its vertical end coned to any suitable angle and the bore or orifice made
blank or in the solid and the coned periphery having four or other number of
outlet holes, the total area of which equals the main orifice (as shewn in plan on
Fig. A 1) and having a ring or collar at the base of the cone. B, is the circular
shaped part of the bracket F, and encirculing the india-rubber pipe C, and the
parallel part of the pipe A. C, is the pipe composed of india-rubber, or other
suitable material, of parallel but varied diameters, from one or both ends, or coned
at one end, or between the two parallel lengths, and secured to the thimble D.
D, is a thimble connected to and worked by the forked lever E; as shewn in plan
Fig: A 1. E, is the lever supported by the bracket F and having a balance weight
at its handle end to adapt the valve to self closing when in use, and to maintain it
so closed when not in use. The bracket F and its segment guide is constructed,
by preference, in the solid with the circular strap B. G. G. are the coupling
motion-pivots.
In Fig. 2, A, is the pipe corresponding to the foregoing, but with its vertical
branch plain and parallel to the base of its cone and differently geared. B, is a
stuffing-box gland screwing into the stuffing-box C. C, shews in part elevation
and part section the stuffing-box coned to suit the nozzle or conical part of the
main pipe A, and has a pivot on each side to carry the links F. D, is one of four
or any other number of the outlet holes. E, is the conical valve secured to the
blank or solid end of the pipe cone, and taking its seat upon a projection within
the main outlet part of the stuffing-box. F, is one of two links coupling the
crank-lever G, and stuffing-box C. The stuffing-box and valve seating is made
to slide up and down on the parallel and vertical branch part of the main pipe A,
thereby opening and shutting the valve orifice. G, is the crank lever handle for
to put the whole in action. H, is a spring of any shape and suitable strength for
self closing and keeping closed the valve orifice. I, is the spring support in solid
or otherwise of the main pipe A
In Fig. 3, A, is another similar pipe having its vertical branch plain and parallel
but without a conical nozzle. B, is a stuffing-box gland and C the stuffing-box.
D, is the main pipe outlet and valve seating; and E the valve secured to, or in the
solid of, the outlet pipe G. F, is one of four or any other number of outlet holes
from smaller chamber of stuffing-box. G, is the outlet pipe screwed or otherwise
•

page_text: fixed into the stuffing-box chamber; and the valve E is secured thereto as shewn.
H, is one of the two coupling links, and I is the straight lever.
In Fig. 4, A, is the stuffing-box, relief chest, valve seat or seatings and hexagon
end thereto, with an orifice to receive the tube, and a pivot on each side to support
the links E; but in lieu of a hexagon end a flange may be used according to the
size and purpose of the valve. B, is the stuffing-box gland screwed into the
stuffing-box and on to the packing, or the same may be otherwise fitted and
applied. C, is a tube of any suitable length and coned at one end to any suitable
angle for forming the valve. The conical end has in its periphery outlet holes
altogether amounting in area equal to the area of the main orifice: the end of this
valve is open in this arrangement but in some instances both ends are coned and
enclosed by similar stuffing-boxes. D, is the forked lever connected to the valve
by centre pins G, as shewn in half plan. The said lever may be weighted and
gauged for fixing the valve when requisite. E, is one of two coupling links for
connecting the lever and valve, for opening and shutting the valve; but other
arrangements for working the valve can and may be applied, such as the ordinary
hand wheel, box-nut and screw connected and supported by projections or brackets
upon the stuffing-box part of the valve end, or by any other means. F, is the
pivot for supporting the link E, there being one on each side, and G one of the two
centre pins for connecting the lever and valve. H, is one of two coupling pins,
and I the stuffing-box gland of an expansive joint at the parallel end of the valve.
J, is the stuffing-box with hexagon end and with orifice to receive the wrought
iron pipe; or in lieu of this a flange may be used. In case of an expansion joint
not being required the two stuffing-boxes may be made in the solid, or in two parts
securely bolted together.
In Fig. 5, A, is a Ṭ shaped pipe containing stuffing-box and conical valve seating.
B, is a dome shaped cap tapped and screwed on to the gland C; and C is the
stuffing-box gland. D, is the lever space, and F the lever for working the
valve G, I. E, is the spring for keeping the valve down and for self closing it.
G, is the hollow part of valve shank, as shewn in broken or dotted lines, to contain
contents of the pipe A; and for partly, or wholly, equalizing the pressure upon the
said valve, thereby affording better command and general working of the valve.
H, is one of four or any other number of inlet holes. I, is the conical valve
having a ring of india-rubber, or leather, or any other material, secured thereon
for the valve face, or may be in the solid metal in this or any other shaped valve.
Another modification of this figure in my invention may be made to discharge
the contents of the pipe A horizontally or in line with the inlet branch, as shewn
by dotted or broken lines.
In Fig. 6, A, is a T shaped pipe having in its vertical branch a stuffing-box and
conical valve seating. B, is the cap screwed on to and supported by stuffing-box
gland C, the top of which serves as the spring seat and spring chamber combined,
and as a guide for the spring cap F. C, is the stuffing-box gland to which is
screwed the cap B. D, is the valve stalk connecting-rod and secured to the same
at the one end and to the spring cap at the other end, as shewn, or the same may
be constructed in the solid of the valve shank. E, is the spiral spring for self
closing the valve and keeping it up to its seat. F, is the spring cap and spring
guider. G, is the hollow, or tubular, part of valve stalk, as shewn in dotted lines.
The object of this chamber is for the same purpose as previously described in
Fig. 5. I, is the valve seating of leather, india-rubber, or any other suitable
material. J, is one of four or any other number of outlet holes.
This valve, or its stalk, or its connecting-rod D, may have a projection to
prevent turning when arranged to work by a screw, as shewn in Fig. 7. This
form of the valve can also be made to discharge its contents horizontally or in line
with pipe part A, as shewn by dotted or broken lines in Fig. 5.
In Fig. 7, is a section of the arrangement for working the valve as shown in
Fig. 6 or other form of the valve by means of a screw and nut. The nut is made

page_text: to move or turn by means of a loose or fixed key or handle. B, is a cap or
chamber containing the nut D, which cap is screwed on to the stuffing-box gland C
in Fig. 6. this is added when required to work the valve by screw, in place of the
spring or lever arrangement. C, is the valve spindle which may be made in the
solid with the valve, or attached to it, and may have a projection to prevent
the valve turning. D, is a screw motion nut. E, is the screw part of the valve
spindle C. F, is the nut cap screwed into and supported by the upper part of the
chamber B; and G is the hole to receive the handle or key.
Having now particularly described and ascertained the nature of my said
invention and in what manner the saine is to be performed I declare that what
I claim is
The construction of valves, in the solid or tubular, for steam or other purposes,
whether in combination with expansion joints or not, substantially as shewn and
described.
