IMPROVEMENTS IN STOP, AND OTHER VALVES FOR REGULATING THE FLOW OF FLUIDS
Year: 1885

page_text: I HERBERT TROTT of 75 High Street Battersea in the County of Surrey
Engineer do hereby declare the nature of my invention for IMPROVEMENTS IN STOP,
AND OTHER VALVES FOR REGULATING THE FLOW OF FLUIDS to be as follows:-
:-
These improvements relate in part to the description of valve described in the
specifications of Letters Patent granted to me dated the 28th day of August 1884
No 11727 and the 8th day of January 1885 N° 272 and have for their object thé
development or further adaptation of the principle of construction therein set forth.
I form my improved valves with inlet and outlet passages the orifices of which
to be closed are brought adjacent and so as to be closed by one valve piece of the
character described in said specifications hanging suspended or hinged so as to be
capable of being swung against an inclined face and there retained so as to open
and close both inlet and outlet openings to the respective passages under the
influence of a wedge or other equivalent means of operation pressing against of
connected thereto or the said closing part may be double.
•
The valve and valve parts may be constructed of glass, metal or other suitable
material not likely to be injuriously acted upon by corrosive or other fluids.
The acting face of the closing piece or pieces or valve proper may be made of
rubber or other suitable material and suitably secured to the face of that valve
piece. By these means both inlet and outlet pressures are cut off from access to
the valve case when the passages are shut.
Or the arrangement of these opening and closing means may be such that the
inclined closing piece or pieces with their corresponding seating may act obliquely
to the line of the fluid passages so as to act on the inlet more particularly.

page_text: Figures 14, 15, 16 and 17 shew a modification in form of this valve particularly
adapted to larger sizes, by vertical, horizontal and transverse sectional views and a
plan view respectively.
Figures 18 and 19 shew-by a sectional view and a plan view an arrangement of
valve adapted for effecting closing of one inlet face b only, instead of both faces as
in the preceding figures, the flow being in the direction (say) of the arrows but in
cases where a series of outlets are desired to be arranged to be supplied by means
of one inlet or supply channel and to be capable each of separate control for outflow
I arrange the outflow channels substantially as shewn in Figures 20 to 22-
Figure 20 being a sectional plan-Figure 21 a cross section and Figure 22 a plan
view of an arrangement in which 6 6 6 are three outlet passages for drawing off
fluid supplied by the supply pipe b the direction of flow being indicated by the
arrows. ccc are the respective handles turning in the parts d' for operating
the respective valves at a³ a to open or close the outlets 64 65 66 independently or
these where desired may be made to operate simultaneously by suitable con-
nections-where as for Laundries, Lavatories, Baths, Hair-Dressers' and other places
it is convenient to be able to mix or supply through one outlet or opening two
fluids or fluids of two temperatures. I reverse the flow and make the pipes b* 6º 60
the inlets and b³ the outlet pipe.
A cap properly secured by screwing or otherwise over an opening as at b' may
serve for cleansing.
This arrangement will also be found useful for gas or other fluid.
Throughout these figures c is a handle which may be of any convenient form,
applied to a stem c¹, which is formed with a screw thread c³, taking into a
corresponding screw or inclined thread as formed in the side of the valve chamber d.
and this stem also carries a piece or stem e capable of rotation therein but not of
separation and having an enlarged head e' which links it to the double or forked
hook a of the valve piece a. so that as the handle and stem are rotated they by
means of this piece e. draw or force the valve piece a¹ a. from or against the faces
of the openings b, b', or b', bo, 66, as the case may be the valve a swinging on its
projecting horns or lugs as which are supported and held in the recesses d³, at the
head of the valve f in the respective figures is a screwed plug or closing piece held
in place by screws for closing the head opening and for opening the head of the
valve chamber d. for examination, removal, or renewal of the swinging valve
piece a or its flexible pad a¹-62 62 are the screwed or plain ends of the valve for
connection to pipes of supply-g. is a packing plug to adjust the packing to the
valve stem c¹.
In operation, the water or other fluid passing into the one channel and thus to
the opening b. into the valve chamber d, is stopped by the flexible or other pad a¹
of the valve piece a. when that piece a. is pressed home on its inclined seat b. b
by the stem c¹ through the intervention of the piece e, and the opening 6' of the
outlet channel is similarly closed, but then when valve a. is withdrawn the flow
will take place freely through b. into d. and out again through b¹.
The arrangement according to Figure 1. is particularly adapted to a vertical
ourse or channel of flow.
The arrangement Figures 8 to 17 are shewn as for horizontal flow and may be
sed in right hand or left hand flow irrespective of the one or the other end
orming the inlet.
The arrangements of the parts in Figures 18 and 19 may be modified to the
irection in which the angular handle stem c¹ is desired to project.
Having now particularly described and ascertained the nature of my said
vention, and in what manner the same is to be performed, I declare that what
claim is:
1. The arrangements or adaptations and combinations of parts of valves for
ntrolling the supply or passage of fluids by means of one valve piece closing

page_text: both the openings of inflow and outflow substantially as set forth in respect of
Figures 1 to 17.
2. The combination or arrangement of parts forming a valve for controlling.the
flow of fluids as set forth in respect of Figures 18 and 19.
3. The combination or arrangement of a number of valves or closing pieces
constructed and operating as herein mentioned for controlling a number of passages
communicating with a passage common thereto for inlet or outlet as and for the
purposes set forth in respect of Figures 20. 21. and 22.
