PROVISIONAL SPECIFICATION.
Improvements in Water and like Gauges, Cocks, and Valves for
Steam Boiler and other Purposes.
We, JOHN STEPHEN JENNENS and JOHN JENNENS trading as J. and
T. E. Jennens, of Villa Street, Aston Manor, near the City of Birmingham,
Manufacturers, do hereby declare the nature of this invention to be as
follows:-
This invention has relation to water and liquid gauges for steam boiler aud
other uses and also to cocks and valves generally, and has for one of its objects
the closing of the passages or ports; for another object, the prevention of leakage
with the reduction of friction in the moving parts and for another object, to
diminish wear and tear and counteract the effects of expansion and contraction,
and for a still further object, to improve the general construction of such articles.
and effect the easy removal of the wearing parts.
In carrying out our invention in connection with a water gauge, which is an
instrument combining both a cock and an indicator body part, the same consists of
a hollow body having a recessed set-back or chambered and faced inner end with
an excentrically disposed bole, through it, and a socket at its middle for receiving
the gauge glass and with the outer walls of the said socket being screwed for
taking a union or box nut for securing the metallic ferrule of the gauge glass in
position. Lignable with the axis of the gauge glass is a blow-out pipe for
getting rid of any sediment which may accumulate within the interior of the
gauge.
The said body part has an axial and thoroughfare hole through its middle,
wherethrough a spindle with a disc upon its inuer end taking up to the faced end
of the body, passes, whilst the outer end of the said spindle has a handle and a
pointer taking upon a flat and is secured there by a nut taking upon a protruding
screwed end.
Fitted and screwing upon the chambered fure en 1 of the body is a terminal or
cap having within it a stuffing box with an asbestos packing and strung upon the
facetted end, and up to the shoulder, of the spindle is a D-pierced or other
washer. Now the disc on the spindle end, which constitutes the head valve, has a
radial slot in it corresponding in position to the excentric bole in the faced end of
the body, so that by rotating the spindle whilst the disc face comes into close
contact with the body, the passage of water to the gauge glass is cut off or
admitted.
Thus the disc head of the spindle lies within the chambered and faced end of
the body, whilst the spindle, which is located axially within the said body, passes
first through the said faced back end, through the body chamber, and then through
a hole in the front wall of the chamber, through the stuffing box located in the
fore end and through the gland, the end of the cap, D-pierced washer, handle and
pointer and finally through the nut on the end. The handle is D-pierced to take
upon the flat of the spindle for preventing rotation.
The top fitting of the gauge is constructed just the saine as the lower one, but
with the socket for the gauge glass depending downwards and with a hole in the
top lignable with the gauge glass and through which access is gained for cleansing
purposes. closed by a screw stopper.

page_text: OPERATION.
Assuming that the lever of the lower fitting is erect and the lever of the lower
one depends, with the pointer of the former directed downwards, and that of the
latter upwards, then the holes in the disc valves are coincident with the passages
through the faces, thereby making open thoroughfare passages from boiler to
gauge glass, within which water rises and indicates the height of water in the
boiler.
By now turning the handles and rotating the spindle in the opposite direction,
the quadraut slotted hole in the disc is then brought opposite the closed part of
the face and the passage of water through the lower fitting is cut off.
Now should the gauge glass break when the gauge is in operation the attendant
. immediately turns the handles and shuts off both water anl stean, thereby
preventing scalding and blowing out as is common in ordinary ganges.
No sediment can accumulate between the faces of disc and body in consequence
of the same being disposed vertically.
The application of our invention to gauges for water and oil tanks and the like
differs in no essential respect from a steam boiler gauge as described and in
applying our invention to cocks and valves, the glass socket is dispensed with and
the blow out hole made to constitute the bib or outlet.

Improvements in Water and like Gauges, Cocks, and Valves for
Steam Boiler and other Purposes.
We, JOHN STEPHEN JENNENS and JOHN JENNENS trading as J. and
T. E. Jennens of Villa Street, Aston Manor, near the City of Birmingham,
Manufacturers, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particulay described and ascertained in and by
the following statement:-
This invention has relation to water and liquid gauges for steam boiler and
other uses and also to cylinder drain-cocks, and to cocks and valves generally, and
has for one of its objects, the more efficient closing of the passages or ports; for
another object, the prevention of leakage with the reduction of friction in the
moving parts, and for another object, to diminish wear and tear and counteract
the effects of expansion and contraction, and for a still further object, to improve
the general construction of such articles and effect the easy removal of the wearing
parts.

top fitting of a water gauge constructed and arranged in accordance with our
invention.

constructed.

The same letters of reference indicate corresponding parts in the several figures
of the drawings.
In carrying out our invention in connection with a water gauge as shown, which
is an instrument combining both a cock and an indicator, the same consists of a
top fitting A, and a bottom fitting B, each comprising a hollow body part a,
having a recessed set-back or chambered and faced inner end a¹, with an
excentrically disposed hole a², through it, and a socket a³, at its middle for
receiving the gauge glass b, and with the outer walls of the said socket being
screwed at a, for taking a union or box nut as which secures the metallic ferrule 6,
of the gauge glass in position. Lignable with the axis of the gauge glass (in the
case of a bottom fitting) is a blow-out pipe a, for getting rid of any seliment
which may accumulate within the interior a', of the gauge.
The said body part has an axial and thoroughfare hole a", through its middle,
wherethrough a spindle c, with a disc c', upon its inner end taking up to the faced
end a, of the body, passes, whilst the outer end e, of the said spindle has a
handle c, and a pointer e, taking upon a flat c, and is secured there by a nut c,
taking upon the protruding screwed end e.
Fitted and screwing upon the chambered fore end of the body a', is a terminal or
cap d, having within it a stuffing box d', with an asbestos packing d², and strung
upon the facetted end c, and up to the shoulder e", of the spindle is a washer a
Now the disc e', on the spindle end, which constitutes the head valve, has a radial
slot e, in it corresponding in position to the excentric hole a², in the faced end a',
of the body, so that by rotating the spindle whilst the dise face comes into close
contact with the solid faced end of the body, the passage of water or steam to the
gauge glass is cut off or admitted.
Thus, the disc hend on the spindle lies within the chambered and faced end a',
of the body, whilst the spindle, which is located axially within the said body passes
first through a hole a ia the said faced back end, through the body chamber a',
and then through a hole a', in the front wall of the chamber, through the stuffing
box d', located in the fore end and through the gland, the end of the cap d, the
washer e, and handle and pointer e, e, and finally through the nut e, on the
end d. The handle is D pierced at e" to take upon the flat o of the spindle for
preventing rotation.
The mouth of the chambered end a¹, is screwed to take a hollow connection e,
by which the gauge is connected to a boiler.
The top fitting of the gauge is constructed just the same as the lower one, but
with the socket a³, for the gauge glass depending downwards and with a hole in
the top lignable with the gauge glass and through which access is gained for
eleansing purposes, closed by a screw stopper J.
OPERATION.
Assuming that the lever or handle of the lower fitting is erect and the lever or
handle of the lower one depends with the pointer of the former directed
downwards, and that of the latter upwards, then the holes in the disc valves are
coincident with the passages through the faces, thereby making open thoroughfare
passages from the boiler to the gauge glass, within which water rises and indicates
the height of water in the said boiler.
By now turning the handles and rotating the spindle in the opposite direction,
the quadrant slotted hole in the disc is then brought opposite the closed part of the
face and the passage of water through the lower fitting is cut off.
Now should the gauge glass break when the gauge is in operation the attendant

page_text: immediately turns both the handles and shuts off both water and steam, thereby
preventing scalding and blowing out as is common in ordinary ganges.
No sediment can accumulate between the faces of disc and body in consequence
of the same heing disposed vertically.
The application of our invention to gauges for water and oil tanks and the like
differs in no essential respect from a steam boiler gauge as described, and in
applying our invention to cylinder drain cocks and other cocks and valves, the
glass socket is dispensed with and the blow out hole made to constitute the bib or
-outlet.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
First. In the fittings of water gauges, opening and closing the port or ports by
means of an excentrically pierced or slotted head valve or disc, rotated by a spindle
and working or rotating against the slotted or pierced faced and chambered end or
part of the body of the fitting, substantially for the purpose described.
Secoudly. The improvements in the means for opening and closing the ports or
passages of water gauge fittings, whereby the said opening and closing is facilitated
substantially as described and set forth in the several figures.
Thirdly. In the fittings of water gauges, the general construction, arrangement
and combination of the parts, substantially as and for the purpose described and
-set forth.
Fourthly. The application to valves, cocks and taps, of the improved means for
-opening and closing the ports or passages herein described.
