Year: 1873

page_text: LETTERS PATENT to Frank Wirth, of the Firm of Wirth and Company,
Patent Agency, at Frankfort-on-the-Main (Germany), for the In-
vention of "A NEW HEATING APPARATUS FOR PASSENGER RAILWAY
CARRIAGES."-A communication from Edward Eichwede, Engineer,
residing at Hannover (Germany).
PROVISIONAL SPECIFICATION left by the said Frank Wirth at the
Office of the Commissioners of Patents, with his Petition, on the
8th August 1878.
I, FRANK WIRTH, of the Firm of Wirth and Company, Patent Agency,
at Frankfort-on-the-Main (Germany), do hereby declare the nature of
the said Invention for "A NEW HEATING APPARATUS FOR PASSENGER RAILWAY
CARRIAGES," a communication to me from Edward Eichwede, Engineer, a
person resident at Hannover (Germany), to be as follows :— ·
This Invention consists in improved apparatus for heating railway
arriages and other like vehicles.

page_text: The heating apparatus is arranged midway the length of the carriage
upon the outside thereof below the floor, and consists of a metal casing
or cylinder mounted upon suitable bearings, and having a door for closing
the same.
Within this cylinder is placed a moveable "fire basket" for
containing the fuel, over which is a wirework lid or cover.
The air for combustion enters by suitable inlets beneath the cylinder,
and a pipe is provided with an exhaust apparatus for drawing off the
gasses of combustion. The cylinder containing the fire basket is further
enclosed by a concentric casing, from which outer casing the heat con-
ducting pipes are carried, which pipes are arranged within the compart-
ments in any convenient manner.
A non-conducting plate is fitted above the apparatus to prevent the
ill effect of the radiant heat upon the woodwork of the carriage.
The fire basket may be inserted from either side of the cylinder, and
the apparatus being arranged beneath the carriage does not in any way
interfere with the proper use and ordinary working thereof.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Frank Wirth in the Great Seal Patent Office on
the 7th February 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FRANK
WIRTH, of the Firm of Wirth and Company, Patent Agency, at Frank'
fort-on-the-Maine (Germany), send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria by Her Letters
Patent, bearing date the Eighth day of August, in the year of our
Lord One thousand eight hundred and seventy-three, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Frank Wirth, Her special licence
that I, the said Frank Wirth, my executors, administrators, and
assigns, or such others as I, the said Frank Wirth, my executors,
administrators, and assigns, should at any time agree with, and no a
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the

page_text: Channel Islands, and Isle of Man, an Invention for "A NEW HEATING
APPARATUS FOR PASSENGER RAILWAY CARRIAGES," a communication from
Edward Eichwede, Engineer, a person resident at Hannover (Germany),
upon the condition (amongst others) that I, the said Frank Wirth, my
executors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the same
was to be performed, and cause the same to be filed in the Great Seal
Patent Office within six calendar months next and immediately after the
date of the said Letters Patent.
NOW KNOW YE, that I, the said Frank Wirth, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the.
following statement, reference being had to the accompanying Sheet of
Drawings, and to the figures and letters marked thereon, that is to
say:-
This Invention consists in improved apparatus for heating railway
carriages and other like vehicles.
The manner in which this Invention is to be performed will be clearly
understood by the following particular description thereof, reference being
had to the Figures and letters on the accompanying Sheet of Drawings,
in which Figs. 1 and 2 are longitudinal and end elevations; and Fig. 3
a sectional plan of a railway carriage, with one arrangement of my
improved heating apparatus.
Figs. 4, 5, and 6 are enlarged views of the apparatus detached; and
Figs. 8, 9, and 10 are views of some of the parts.
Below the floor A of the carriage there is a space enclosed by a hori-
zontal facing or bottom B and four walls or sides, and below this space
midway the length of the carriage is placed the heating apparatus, which
consists of a sheet metal cylinder or casing a, mounted on suitable
bearings or supports, and having a door 6 for closing it. Within this
cylinder is placed a portable fire-box for containing the fuel, there being
at the bottom perforations or bars, and at the top a movable wirework
COVER.
The air nonmined to promote combustion anborn ha

page_text: pipefis connected an exhaust apparatus to take off the gases or products
of combustion.
The sheet metal cylinder or casing a is concentrically enclosed by a
double jacket or coating 9, g, g', having connected to it the heat con-
ducting pipes h, h, which pass into the compartments of the carriage,
and are arranged in any convenient manner. The openings k allow the
return of the air when cooled to the passages 7, from whence it passes to
the heating apparatus and again through the pipes h, h, to the compart-
ments, the heat emitted by the pipes passing through openings o, o.
Above the apparatus is fitted a safety plate i for preventing the wood-
work of the carriage from being injuriously affected by the heat, and the
fan or air sucker m is employed to introduce fresh air to the compart-
ments, the air passing under the safety plate to be warmed, and at the
top of each compartment there is a ventilator p to carry off the respirated
air, and to regulate the temperature.
The fire-box c may be inserted from cither side of the cylinder a, and
it will be seen that as the apparatus is arranged beneath the carriage all
the compartments and working parts are casily accessible.
Having thus described the nature and particulars of the said Invention
I claim, the new heating apparatus for passenger railway carriages and
other like vehicles, substantially as described and illustrated on the
accompanying Sheet of Drawings.
In witness whereof, I have hereunto set my hand and seal, this
Twelfth day of January, in the year of our Lord One thousand
eight hundred and seventy-four.
