PROVISIONAL SPECIFICATION left by the said Henry Tipping at the Office
of the Commissioners of Patents on the 24th May 1883.
HENRY TIPPING of 5 Circus Street Greenwich in the County of Kent Engineer.
"IMPROVEMENTS IN APPARATUS EMPLOYED IN GENERATING STEAM FOR USE IN
MARINE AND OTHER ENGINES."
The invention has reference to the description of steam generating apparatus in
which series of tubes are employed in the boiler as in the locomotive type of
boilers.
The object of the invention is to produce an improved steam generating
apparatus particularly adapted for yachts torpedo boats and other vessels requiring
a light durable economical and rapidly generating steam boiler.
In carrying out my invention I form the boiler or water space of the apparatus
of cylindrical or such like form with the fire box at one end and the smoke stack
at the other-the intervening lower portion being occupied by the tubes arranged
in series as in locomotive boilers generally. I however arrange these boiler tubes
and parts of the boiler on an angle inclining towards the fire for convenience of access
from the smoke stack for cleansing as well as for the facility afforded for heating.
The crown or upper portion of the fire box I form of a circular cross section and
the plate forming the front and back thereof is in one piece carried up from the
lower front end over the crown and down to the lower back end of the fire box the
side plates being secured by rivetting as usual. Suitable stays are provided to
such pertions of the boiler space as may be desirable but their number and
arrangement will depend on circumstances.
The fire bars occupy the lower portion of the fire box and the fire box is
accessible through a fire door pierced through the said continuous plate-A suitable
mud hole and its accessories are provided at the smoke stack lower end of the
boiler.

page_text: According to another portion of my invention I form at the upper portion or
crown of the fire box a tubular passage upwards through the boiler and opening
upwards and downwards therethrough so as to be accessible from above Within
this tubular passage I arrange a coil of piping communicating at one end with the
feed for supply of water to the boiler and at the other end with the interior of the
boiler. The opening in this passage through the boiler case being closed by
suitable nonconducting closing means. The opening of the coiled pipe into the
boiler is closed by a valve adjustably arranged to work in suitable seating so as to
be self acting or capable of being controlled by a rod or connection passing to the
outside of the boiler casing for its being opened or closed at will. By these means
the water thereby introduced into the boiler will be greatly heated previous to its
entry and economy of heating power secured.
The above described arrangement of parts for securing the heating of the feed
water before its supply to the boiler may be applied to other forms of marine
locomotive and stationary boilers and such like steam generating apparatus than
that already described.

"IMPROVEMENTS IN APPARATUS EMPLOYED IN GENERATING STEAM FOR USE IN
MARINE AND OTHER ENGINES
The invention has reference to the description of steam generating apparatus in
which series of tubes are employed in the boiler as in the locomotive and other
multitubular type of boilers
The object of the invention is to produce an improved steam generating
apparatus particularly adapted for yachts, torpedo-boats, and other vessels requiring
a light, durable, economical and rapidly generating steam boiler.
In carrying out my invention I form the boiler or water space of the apparatus
of cylindrical or such like form with the fire box either at one end or part and the
smoke stack at the other end or otherwise as may be found most convenient and
when the fire box is arranged at one end with the smoke stack at the other end
the intervening lower portion is occupied by the tubes arranged in series for instance
as in locomotive and other descriptions of multitubular boilers. I however arrange
these boiler tubes and parts of the boilers on an angle inclining towards the fire
for convenience of access from the smoke stack for cleansing as well as for the
facility afforded for heating. The crown or upper portion of the fire box I form
of a circular cross section and the plate forming the front and back upper portion
thereof may be in one piece the plate being carried up from the lower front end
over the crown and down to the lower back end of the fire box the side plates
being secured by rivetting as usual. Suitable stays are provided to such portions
of the boiler space as may be desirable but their number and arrangement will
depend on circumstances
The fire bars occupy the lower portion of the fire box and the fire box is acces-
sible through a fire door pierced through the said continuous plate. A suitable
mud hole and its accessories are provided at the smoke stack lower end of the
boiler
According to another portion of my Invention I form at the upper portion or
crown of the fire box a tubular passage upwards through the boiler and opening
upwards and downwards therethrough so as to be accessible from above. Within
this tubular passage I arrange a coil of piping communicating at one end with the
feed for supply of water to the boiler and at the other end with the interior of the
boiler. The opening in this passage through the boiler case being closed by
suitable nonconducting closing means. The opening of the coiled pipe into the
boiler is closed by a valve such as an ordinary boiler check valve or other suitable
valve adjustably arranged to work in suitable seating so as to be self acting or
capable of being controlled by a rod or connection passing to the outside of the
boiler casing for its being opened or closed at will. By these means the water,
thereby introduced into the boiler, will be greatly heated previously to its entry
into such boiler and consequent economy of heating power secured.
In the accompanying drawings Figure 1. shows a longitudinal section of the
apparatus when arranged with the fire box a at one end and the smoke stack b
at the opposite end of the boiler c, the intervening lower portion being occupied
by tubes d, in series, set on an angle inclining downwards from the smoke stack
towards the fire. a¹ is the crown or upper portion of the fire box a, of circular
cross section, and with the upper portion (1) (1) in one piece. e are stays, ƒ are
'

page_text: fire bars in the lower portion a² of the fire box. g indicates the position of a mud
hole. Figure 2 is a cross section of the same arrangement in part and partly an
end view thereof. Figure 3 shews by a longitudinal section and Figure 4 by a
cross section apparatus arranged for carrying out the invention when a return
flue is used. In these figures like letters indicate similar parts wherever they
occur. h is a tubular passage, or pipe, carried up through the boiler c. from the
upper portion or crown a¹ of the fire box a and opening upwards at h¹ and
downwards at h² therethrough so as to be accessible from above. i is a coil of
piping arranged within the tube h communicating at one end with the feed
for supply of water (the feeding means not shewn) and at the other end 12 with
the interior of the boiler. k is a nonconducting closing piece to the opening in
the boiler case thus formed. 7 indicates the position of a valve for controlling
automatically, or by handle 1, the opening of the coil pipe into the boiler. The
separate view, Figure 5, indicates such a valve to a larger scale as would be
suitable to the purpose but other forms of valves may be employed as will be
evident to any one acquainted with the subject. In this Figure 5 h indicates a
part of the tube for the coil i. c* indicates a part of the shell of the boiler c.
is the valve and the handle to the screw rod for closing the valve 7 when
required.
E
The above described arrangement of the parts for the supply of water fed to
the boiler whereby the heating of such water before its entry into the boiler is
attained may be applied to other forms of locomotive and stationary engine boilers
and such like steam generating apparatus, than those already described with like
economy and advantage
1.
Having thus described the nature of my Invention and means adapted for
carrying the same into practical effect I would have it understood that what I
claim is the general arrangement and combination of the parts of steam generating
apparatus for steam and other engines, substantially as described and shown.
Also I claim the arrangement of the parts for securing the heating of the feed
water before its supply to the boiler in steam generating apparatus for steam and
other engines substantially as described and shewn.
In witness whereof I the said Henry Tipping have hereunto set my hand and
seal this Fourteenth day of November in the year of our Lord One thousand
eight hundred and eighty three.
