AN IMPROVEMENT IN WASTE STEAM PIPES
Year: 1877

page_text: LETTERS PATENT to Paul de Sa, of East View, Dover Street, Ryde, in the Isle
of Wight, in the County of Southampton, Photographer, and Charles Hobbs,
of Orchardleigh, Pellhurst Road, Ryde aforesaid, Gentleman, for the Invention
of "AN IMPROVEMENT IN WASTE STEAM PIPES."
Sealed the 21st December 1877, and dated the 3rd August 1877.
PROVISIONAL SPECIFICATION left by the said Paul de Sa and Charles
Hobbs at the Office of the Commissioners of Patents on the 3rd August 1877,
PAUL DE SA, of East View, Dover Street, Ryde, in the Isle of Wight, in the
County of Southampton, Photographer, and CHARLES HOBBS, of Orchardleigh,
Pellhurst Road, Ryde aforesaid, Gentleman. "AN IMPROVEMENT IN WASTE STEAM
PIPES."
This Invention consists in the construction and application of a series of tubes or
pipes which are arranged and respectively composed in a concentric form, by means
of which a thorough passage to carry off the excess steam is promoted, and the
products arising from the priming of the boilers are removed whilst the possibility
of any discharge of steam, water, or foreign matter arising from such priming
passing over the head of the steam pipe to the annoyance of passengers is entirely
obviated.
The main and effective portion of this Invention is, that between these series of
pipes a cylinder of a suitable form, such as that of a truncated cone, is so arranged
that the said pipes from the receiver or flange enter into the uppermost portion of
the cone in a concentric form at equal distances apart from each other. The lowest
portion of the cone is so constructed that a discharge or outlet pipe carries off all
access of steam, water, or foreign matter caused by the priming of or fermentation
of the water in the boilers, while a perforated head of metal is attached to the
aforesaid cone to assist in carrying off the vapour arising from the excess of steam.

"
PAUL DE SA, of East View, Dover Street, Ryde, in the Isle of Wight, in the
County of Southampton, Photographer, and CHARLES HOBBS, of Orchardleigh,
Pellhurst Road, Ryde aforesaid. THE PREVENTION OF WATER ACCOMPANYING
STEAM TO THE CYLINDER, AND ALSO FOR PREVENTING WATER AND FOREIGN
MATTER FROM COMING ON DECK IN THE EVENT OF THE BOILERS PRIMING."
This Invention consists in the construction and application of a series of tubes or
pipes, which are arranged and respectively composed in a concentric form.
Figure 1; Main Steam Pipe.-The water arising from condensation or priming
of the boilers on its transit to the cylinders, passing through A, B, and C, must fall
into the tank D, allowing dry steam only to pass through E and F into the
cylinders, and will assist in preventing the non-condensed vapour arising from
particles of water always accompanying the steam in its transit from the boilers to
the cylinders from accumulating, and improve the vacuum in the condenser. By
ecting with G the condensed water may be carried to the suction of the small
te for supplying the boilers.
Figure 2; Waste Steam Pipe.-In this case the water and foreign matter arising
from the priming of the boilers are carried off by passing from steam pipe A
through receiver B and conduits C through the pipes D, discharging. through
truncated arm E, F, into a tank or bilge, the steam passing off through G. By
this means the possibility of the discharge of steam, water, or foreign matter arising
from priming, and passing over the head of the steam pipe to the annoyance of
passengers, is entirely obviated.
In witness whereof, they, the said Paul de Sa and Charles Hobbs, have
hereunto set their hands and seals, this Twenty-third day of October, in
the year of our Lord 1877.
Signed, sealed, and delivered by the
said Paul de Sa and Charles Hobbs
