Eyelet Manufacturer do hereby declare the nature of this invention to be as
follows:-
My invention has for its object to construct a simple and effective device or valve,
having few working parts, and is adapted to afford immediate communication between
the thoroughfares or orifices which it, may intercept. My improved valve. may be
used for the purpose of supplying or admitting steam or other gases to motive power
and other machines, and inay be utilised for the purposes of a steam trap for dis-
charging condensed steam from pipes, also for allowing liquids under pressure or by
means of gravitation to pass from a convenient supply source to any desired place
of discharge.
My arrangement consists of providing a metal or other piece of suitable form which
I term a "junction piece" preferably being a piece having two projections extending
from the same side of such piece, and opposite to each other, being a convenient
distance apart; the projections are hollow, forming a chamber in. each, between the
projections is situate a metal or other suitable hollow tube, its extremities terminating
and passing into the chamber of the projecting pieces, through suitable packings
provided at their entrances. At a convenient part of each chamber, in line with the
axis of the hollow tube, is a thoroughfare having a screw thread, into which is fitted
the supply and discharge pipe respectively being at opposise ends of the tube, and
forming the inlet and the outlet of the valve. One end of the hollow tube is closed,
which end is situated in the inlet chamber or portion of the valve, the other end of
the tube is open; at or near the closed end of the tube and around its surface, is
provided a series of slots or openings. The tube is fitted so as to be free to slide in
the direction of its axis, which is effected by means of a suitable lever, or may be
effected by other convenient mechanism; accordingly as the perforated end or part
of the tube is caused to pass out of, or into the inlet chamber of the valve, the gas or

page_text: liquid as the case may be passing from the inlet pipe, is accordingly shut off from or
admitted into the discharge or delivery pipe, or outlet portion as in the first case com-
munication is shut off between the interior of the tube and the inlet chamber but in
the second case a communication is opened between the same.

Agent to the Applicant.
I, JAMES BUTTERWORTH, of Elliott Street Works, Rochdale, in the County of
Lancaster, Eyelet Manufacturer, 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 :-
My invention has for its object to construct a simple and effective valve having few
working parts adapted to afford immediate communication between the thoroughfares
or orifices which it may intercept.
My improved valve may be used for the purposes of supplying or admitting liquids,
steam, or other gases to motive power, or other machines, and for other purposes for
which valves may be used.
My arrangement consists of providing a metal piece or other suitable material
which I term a "junction piece," being a piece having two projections from the same
side of such piece, and opposite to each other, being a convenient distance apart; the
projections are hollow, forming a chamber in each, or the said projections or chambers
may be in two parts, between the projections is situate a metal or other suitable
hollow tube, its extremities terminating and passing into the chambers of the pro-
jecting pieces through suitable packings provided at their entrances.
At a convenient part of each chamber in line with the axis of the hollow tube is a
thoroughfare having a screw-thread into which is fitted the supply and discharge
pipe respectively being at opposite ends of the tube and forming the inlet and outlet
of the valve.
One end of the hollow tube is closed which end is situated in the inlet chamber of
the valve, the other end of the tube is open which end is situated in the outlet portion
of the valve, at or near the closed end of the tube and around its surface is provided
a series of perforations slots or openings.

page_text: as the case may be for in the first case communication is shut off between the
interior of the tube and the inlet chamber but in the second case a communication is
opened between the same.
Herewith I append a sheet of drawings which fully illustrate my invention like
letters of reference in the figures therein shewn indicate like parts.
DESCRIPTION OF DRAWINGS.
Figure 1 represents a sectional elevation of my invention shewing the position of
the valve spindle when the valve is opened or in operation.
Figure 2 represents a side elevation of so much of Figure 1 as is necessary to
illustrate my invention shewing the means by which the valve spindle is operated.
Figure 3 is an end elevation of Figure 2 through a. b.
I construct the extremities or hollow casings c. e¹ of the valve, which may be of
circular or any other desired form in two separate pieces, which pieces are situated
at any convenient distance apart from one another, opposite to each other and in the
same axial line being connected by means of connecting pieces d d' of any suitable
length having screw threaded extremities and provided with screw threaded nuts e. e.
and e¹ el but if desired I may form the said extreniities in one piece or casting being
connected together by metal pieces extending from one to the other.
In the space between the casings c. c¹ I provide or interpose a tube or hollow
spindle of any suitable form, the extremities of the said tube enter into chambers g. g¹
formed in the hollow casings c. c' the said spindle being solid or closed at one end h.
and provided around its side or sides with suitable or openings which end is
situated in the inlet chamber g.-the other end of the spindle being open and situated
in the opposite chamber g¹ or outlet portion of the valve, the said spindle at the
entrances to the chambers is surrounded by suitable packing i which is maintained
in position by suitable glands jj and screw threaded pieces k. by which means
leakage of gas or liquids between the casings and spindle is avoide.l, the said spindle
is free to move or slide endwise or in the direction of its axis, which is effected by
means of a suitable handle 1. engaging with the spindle by means of studs m m which
handle when moved by the hand of the operative is free to turn about the surface
of the fixed stud n. provided on the connecting piece d; which for instance being
moved to the position as indicated by the dotted lines in Figure 2 when it is desired
to operate the valve such position as indicated would have the effect of opening the
valve admitting gas or liquids from one chamber to the other.
The extremities of the chambers g. gl-that is the parts opposite to the entrances
through which the extremities of the spindle pass-terminate with thoroughfares or
orifices around the interior of the said terminal parts being provided with screw-
threads and which are prepared to receive the abutting ends of pipes or tubes o. o'
which it may be necessary to attach my improved valve, the hexagon shaped exterior
parts p. p and the interior screw thread may be dispensed with in case flanges may
be desired as the case may be for instance when it is necessary to connect my valve to
the flanged extremities of pipes or tubes.
The operation of my invention is as follows:-
When the spindle is moved to the position as shewn in Figure 1 the gas or liquid
passing from the pipe or tube. c. is allowed to enter the hollow spindle. through
the apertures thus to pass from the chamber y, to the chamber gf to outlet pipe o¹
when the movement of the spindle is reversed the apertures pass into the throat of
the piece c. the apertures then being obviously covered by the surrounding packing i.
the closed end h. then being presented to the interior of the chamber thus the passage
of gas or liquid is obstructed and the valve is closed.

page_text: Having now particularly described and ascertained the nature of this my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1st. In a valve the use and application of a tube or spindle having a sliding action
the one end entering and being situate in a chamber having a communication with an
inlet orifice, its other end entering and being situate in an outlet chamber having a
cominunication with an outlet orifice, for the purposes herein fully set forth and
described in the drawings hereunto annexed.
2nd. The combination of the hollow spindle f. with the enclosed chamber g. g and
the lever . studs in and n. substantially as and for the purposes herein fully set forth
and described in the drawings hereunto annexed.
3rd. The combination of the casings c. c¹ the glands. the connecting rods or
pieces e. e and e¹ el substantially as and for the purposes herein fully set forth and
described in the drawings hereunto annexed.
