PROVISIONAL SPECIFICATION.
An Auxiliary Flush-valve Steam-trap.
We JOHN RICHARD BADGER Engineer, 16 Hardy Street, Rotherham, and
WILLIAM BADGER, Consulting Engineer, 16 Hardy Street Rotherham do hereby
declare the nature of this invention to be as follows:-
The application of an auxiliary-compound-valve in combination with a direct-
acting float valve, thereby, insuring an enlarged area of opening for the rapid
outflow of condensed steam and water from the trap.
In this arrangement the combined steam and water enter at the crown C of the
steam-trap and by passage ports b, enters the interior at the bottom. The water
rising in the "trap" lifts the float valve G from its seat x, and passing down the
centre of the auxiliary-compound-valve J K to the under-side of the piston K of
the said valve, rapidly raises this valve from its seat, and opens an enlarged area to
discharge a flush of water from the trap. Substantially as described in the drawings
annexed.

We JOHN RICHARD BADGER Mechanical Engineer, 16, Hardy Street
Rotherham, and WILLIAM BADGER Consulting Engineer, 16, Hardy Street,
Rotherham in the County of Yorkshire 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 for its object, the rapid discharge of condensed steam and
water, from the steam-pipes, steam cylinders and other steam-vessels, to which it
may be applied. In its construction, there is a special arrangement to cope with,
and discharge the flush of water in the steam-pipes, and steam-cylinders, when the
steam-boilers are priming, or, when the steam is first turned into the steam-pipes
when cold.
In this invention we construct, arrange, and apply, to a steam-trap, an auxiliary-
compound-flush-valve, in combination with a float and valve, (direct-acting or
otherwise) thereby, ensuring an enlarged opening, for the rapid outflow and
discharge of condensed steam and water from the trap.
In this arrangement the steam and water are admitted preferably at the crown,
or near the top of the steam-trap, and are conveyed by a jacket-passage to the
interior at or near the bottom. The water as it rises in the steam-trap, lifts the
float E. and valve I. from its seat l', and then passing down the centre of
auxiliary-compound-flush-valve J. K. to the under side of the piston-part K. of
the said valve, rapidly moves this against the shoulder formed on the valve-stalk O.
and lifting the valve J. from its seat P. opens an enlarged area to discharge the
water from the trap.

drawings.

Sheet 2. Fig. 1. is an enlarged sectional elevation of valve-box.

DESCRIPTION OF DRAWINGS.
Sheet 1. Fig. 1. and Fig. 2.
These drawings shew the improved steam-trap as designed to be suspended from
steam-pipes and steam-cylinders.
A. A. is preferably a metallic spherical, or round-shaped vessel made in two or
more parts, with flanges and bolts for connecting together.
B. is a flange preferably cast upon the upper part of the vessel A. A. to connect
same to the steam-pipes.
•
C. C. is a metallic, spherical, or round shaped vessel, made in two or more parts,
and suspended in the outer vessel A. A. by the flanges D. D. and thus forms
a shield or protector to the hollow float E. from the inrush of steam and water...
This inner suspended vessel C. C also forms the annular jacket passage F. F. F.
which directs the current of steam and water to the interior of the said vessel C. C
through the inlet at G. G.

page_text: in a conical-valve I at its lower end. The upper end works in a guide-bush♬
formed in the crown of the inner vessel C. C.
h. h. are small holes drilled in the hollow spindle H, opening to the interior of
the float at the bottom.
i. is a small hole, drilled through the inner casing C. C. to admit steam.
N. N. N. N. N. N. N. are passage holes bored in the flanges D. D.
At the bottom of the outer casing A. A. is the valve-box L. with discharge outlet
chamber M. M. and pipe m.
W. is a loose cover, bolted or screwed to the bottom of the valve-box L.
This valve-box may be cast on as shown, or affixed to the outer vessel with flanges,
screws & nuts.
Fig. 1. and Fig. 2. Sheet 2. shew the compound-auxiliary-flush-valve J. K. and
valve box L. on an enlarged scale. J. K. consists preferably of a winged valve J.
having a prolonged hollow-end or stalk O. which forms a sleeve, or mounting, for
the piston-valve K. which is preferably made a sliding fit upon the stalk ▸ for easy
removal and examination.
P. R. is preferably a combined-valve-seat P. and cylinder casing R.
The winged valve J. works in the seating P. and the piston-valve K in the
cylinder R.
Thro' the centre of the valve J. K. an aperture S. s. leads from the interior of
the vessel A. A. to the underside of the piston K. The upper end of this aperture
terminates in a valve-seating 1' which is closed by the floating valve I.
t. t. t. t. are apertures formed in the valve-cylinder-casing, and leading to the
annular chamber M. M. and discharge outlet-pipe m.
W. is a loose cover, closing the bottom of the valve-box L.
Fig. 1. and Fig. 2. Sheet 3. shew drawings of another form of the improved
steam-trap, for fixing on a bracket cr floor.
In this arrangement the steam and water enter the outer vessel A. A at b. and
passing into the jacket c. c enter the interior vessel at the bottom d. d.
J. K.
The construction and arrangement of the auxiliary-compound-flush-valve
is substantially, the same as previously described in Fig. 1. and Fig. 2. Sheet 2.
In this arrangement, however, the steam is admitted to the interior of the vessel
at the top-by a passage port e. formed in the cover f. f. leading to an annular
chamber 9. formed in the boss, cast on the inner side of the cover f. f., thence
through several small holes i. i. drilled in the gun-metal bush fitted in the
Baid boss.
Mounted on the hollow float spindle H. at its upper end, is a piston-valve n.
working in the cylindrical bush h. The object of this arrangement and construction,
ie to close the entrance of steam to within the vessel-during the discharge of water
from the trap, and is effected as follows. As the condensed-steam and water rises
in the vessel, the float E. and valve is raised from its seating, and the piston-
valve n. moves upwards and covers the small holes i. i. shutting of the admission of
steam. By this arrangement the spherical, or other float, discharges itself of any
water caused by the condensation of steam therein-thus ensuring its maximum
floating capacity.
Having now particularly described, and asertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what
we claim is
1. In the construction and arrangement of a steam-trap, the application of an
auxiliary-compound-flush-valve, in combination with a float and valve, substantially
as described.
2. In the construction and arrangement of a steam-trap, the application of a shield,
to protect the float, against the violent inrush of steam and water, substantially as
described.
3. In the construction and arrangement of a steam-trap the application of a

page_text: floating-piston-valve, to close the inlet of steam, during the discharge of water from
the trap; and thereby insure the maximum-buoyancy of the float; substantially as
described.
