Improvements in Valves.
I, HERBERT TROTT of 75 High Street, Battersea, in the County of Surrey,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention has reference to certain improvements in valve apparatus embodying
parts constructed according to the invention embodied in my former Letters Patent
of 28th August 1884 No. 11727; of 26th August 1885 No. 10125; of
9th November 1887 No. 15275; of 5th January 1888 No. 217; or some one or
more of them.
According to this invention the valve chamber is formed with inlet and outlet for
fluid, also with handle or lever stem entrance either screwed or packed otherwise as
may be required; another entrance leading to a recess covered by a screw cap may
be provided to contain an attachment to the valve itself in some cases as will be
described.
The valve may swing on lugs or may be guided by projections from the chamber,
or partly one and partly the other. The exit nozzle or part for fluid is capable of
being unscrewed and removed so as to permit of removal of the valve piece itself for
examination, renewal or repair. The screw stem or other operating part is attached
removably to the valve piece such as by horns on the valve gripping the neck of
an enlargement on the back of the valve."
In some cases to the opposite side of the valve is linked or connected removably a
cup shaped or other valve piece capable of acting on its seating in advance of the
valve proper to arrest flow, and a spring may aid its movement.
The valve may be of metal, asbestos, or combinations thereof or otherwise.
Recessed or projecting parts on either valve or case may be used to maintain the
rectilinear movement of the valve.
The nozzle or exit part when screwed home may be secured from accidental
unfastening by a locking screw passed through nozzle and valve chamber at their
junction.

Improvements in Valves.
I HERBERT TROTT of 75 High Street, Battersea, in the County of Surrey,
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 has reference to certain improvements in valve apparatus embodying
parts constructed according to the invention embodied in my former Letters Patent
of 28th August 1884 No. 11727; of 26th August 1885 No. 10125; of

of them.
According to this invention the valve chamber is formed with inlet and outlet for
fluid, also with handle or lever stem entrance either screwed or packed otherwise as
may be required; another entrance leading to a recess covered by a screw cap may
be provided to contain an attachment to the valve itself in some cases as will be
described.
The valve may swing on lugs or may be guided by projections from the chamber,

DESCRIPTION OF THE DRAWINGS.
Fig. 1 indicates one form of valve arranged for carrying out my invention in a
form adapted for lavatory purposes. This valve is designed to be used with the
spindle of the handle in an upright position and the drawing shews the apparatus
partly in section.
a is the handle for operating the spindle a' which operates the screw a² formed
thereon, which engages the corresponding thread & formed internally of the body of
the valve. c is a screw packing piece for packing the spindle a¹. is the body of
the valve. 61 the valve chamber. d is the exit nozzle which is formed with screw
thread d¹ adapted to engage a corresponding thread formed in the body of the valve.
d indicates one of a pair of recesses which may be formed in the screwed packing
ring d³ for the insertion of a suitable tool which may be employed for turning the
same. This retaining ring d³ serves to retain the valve e in its adjusted position
during its sliding movement even when the nozzle d is removed or when a fire or
other delivery hose connection is applied in place thereof preferably by screwing on
to an exterior thread 68 to the case 6 (indicated by dotted lines in Fig. 1) formed on
a more prolonged extension of that body b. Or the projection for engaging the
recess may be on the valve piece and the recess may be on the case b. e is the valve
piece which has projections e¹ which engage in the grooves 63 formed in the wall of
the body b and serve to guide that valve piece e in its movement. e² is the elastic
face to the valve e, which in the closing of the valve comes against the seat 64 to form
a tight joint. Vertical movements of the screwed spindle a¹ are conveyed to the
valve e by the connection between those parts effected by the horns or projections e³
of the valve e grasping the neck formed between the enlargement a³ and the screwed
portion a² of the stem a¹. The parts a, a and a for connection to a lavatory
apparatus are of the ordinary description.
Fig. 1a shews a modification in detail of the arrangement of the guiding means to
the valve proper in its casing. In this modification the lugs el of the valve piece e
are suppressed, and the lug portion of the valve piece is guided in its rise and fall
between the projections on the case 67, 67, and is also prevented from oscillatory
movement by the recess e in the projection from the valve piece e riding up and
down on a projection 6 from the valve case b.
Fig. 2 shews by sectional view a modification of the arrangement shewn by
Fig. 1 in which is combined a subsidiary valve f connected by a spindle f¹ to an
enlargement 2, which spindle f' below this enlargement is grasped by horns or
projections e from the under face of the valve e. This subsidiary valve serves when
the valve e is removed by the unscrewing of the neck d on its screw thread d¹ to
close the opening g into the valve chamber 6, whilst in the ordinary way of operating
the valve this subsidiary valve fis kept from its seat.
Fig. 3 by sectional view shews another modification particularly designed for use
for filtering purposes. The parts are substantially the same as in the preceding
arrangements.

page_text: Fig. 4 is a front view looking into the valve when the exit nozzle has been
removed.
Fig. 5 shews by sectional view another modification adapted to the use of a self
closing handle has a lever pivoted at to the bracket i, connected to the valve.
This lever passes through and operates the plunger k which passes down and is
normally pressed outwards by the spring / contained in the chamber 55.

that shewn in Fig. 1, the rest of the parts conform to the arrangement shewn in that
Figure.
Fig. 6 is a front view of Fig. 5.
Fig. 7 shews the arrangement indicated by Fig. 1 adapted to an ordinary bib valve.
Fig. 8 is a front view of Fig. 7.
Fig. 9 indicates an arrangement of apparatus adapting the invention to a stop
valve in which m is the inlet passage, d the removable outlet passage secured by a
screw collar d² engaging a corresponding screw thread on the body b. In this
arrangement I have shewn a screw collar d³ engaged in the screw thread formed in
the outlet opening and adjustable therein for retaining the lugs e¹ of the valve piece e
within the groove b³.
The other portions of the apparatus are substantially as shewn
in Fig. 1 except that the dotted lines indicate a removable subsidiary valve similar to
that described in reference to Fig. 2, for use in closing the opening g during
removal of the main valve e.
Fig. 10 shews another modification of the arrangement of valve somewhat similar
to that shewn by Fig. 5. n being a thumb piece to be pressed back turning the cam-
piece n' on its centre n² so as to rock the enlargement n', depress the plunger k

The internal face of this
nozzle d is indicated by Fig. 11.
Fig. 12 shews a section of the same, d² being the outlet passage from the chamber
of the body b to this nozzle.
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 removable exit piece or nozzle in combination with an arrange-
ment of parts of a valve substantially as set forth so as to afford facility for removal
of the valve proper, as e, without disconnecting the valve body as set forth.
2. In a valve, the combination of a removable exit piece or nozzle, as d, so as to
admit of the removal of the valve proper, as e, without disconnection of the valve
body, with subsidiary valve for closing the water way in the body of the valve during
the removal of the valve proper for repairs or otherwise as set forth particularly with
reference to Figs. 2 and 9.
3. In a valve a removable exit piece or nozzle with or without a screwed interior
illing piece d³ for retaining the valve substantially as set forth so as to afford
acility for removal of the valve as e without disconnecting the valve body as
et forth.
4. In a valve a removable exit piece or nozzle with a screwed interior valve
etaining piece d³ for retaining the valve substantially as set forth, in combination
vith a suitable threaded part preferably exterior of the delivery opening as 68
or the attachment of fire or other like delivery hose in place of the said
ozzle as d.
5. The various arrangements or combinations of parts of valve apparatus herein-
efore shewn and described and for the purposes set forth.
