I, JOHN SOMERSET of Gleden Hall Gleden Street Bradford Road Manchester in
the County of Lancaster Gunsmith do hereby declare the nature of my invention
for "IMPROVEMENTS IN APPARATUS FOR WARMING RAILWAY CARRIAGES AND FOR
MELTING AND CLEARING AWAY SNOW LYING UPON A RAILWAY to be as follows:-
دو
In the specification of a former Patent granted to me N° 3503 in the year 1878
I described apparatus for warming railway carriages by means of air heated by
being passed through a coil of pipe placed within the smoke box of the locomotive
engine. Each carriage was provided with a pipe which passed in a zig-zag
direction beneath the seats of each compartment and where it passed across the
doorway or passage between the two seats of a compartment it was carried down
below the floor level. The ends of the pipe on one carriage were coupled to the
ends of the pipe on the adjoining carriage and the foremost end of the pipe on the
front carriage was coupled to a pipe leading to one end of the above mentioned
coil whilst the other end of the coil had fitted to it a trumpet mouth facing
forwards in front of the engine so that when the train was running a current of
air was maintained through the coil and through the pipe on each carriage. In
order that the ends of the pipe on one carriage may be coupled to the ends of the
pipe on the adjoining carriages whether the carriage be placed with ône end
foremost or the other I now form the pipe at each end of each carriage with two
branches projecting from it one projecting out from the end of the carriage at a
short distance from one of its sides and the other from the other of its sides-80
that whichever end of the carriage may be foremost the projecting ends of the
pipes will always be opposite to similar projecting ends of pipe on the adjoining
carriage and can be coupled to them by a screw or bayonet coupling or otherwise.
In order also to more effectually warm the air before passing it through the
pipes on the carriages I not only cause it to pass through a coil of pipe in the smoke
box but also lead the pipe which passes from the outlet end of the coil through the
boiler of the engine.

page_text: In order also to more effectually maintain a current of air through the coil and
the pipe passing from it I mount a small fan or blower on some portion of the
engine and drive it from one of the axles so that it may deliver a continuous
current of air to the coil or the fan might be driven by a small donkey engine so
as to maintain a continuous stream of air through the pipe whether the train be
running or stationary. I also provide means for enabling the stream of heated air
passing from the coil to be directed in a jet against any snow by which the railway
may be obstructed. The jet I mount upon a universal joint at the front end of
the engine so that it may be turned in any direction desired.
In this way I am able to utilize the heated air 'for melting and removing snow
whenever it is required to do so whilst at other times the passage of air through
this jet would be prevented by a stop valve.
Either the same fan might be used for forcing a stream of air through the coil at
the times when the carriages are to be warmed and also at the times when snow is
to be melted or a separate fan might be used at the times when it is desired to
direct a stream of heated air against snow the fan being then caused to deliver a
stream of air to the rear end of the pipe passing through the boiler so that the air
may first pass through this pipe and then through the coil before issuing from
the jet.

I JOHN SOMERSET of Gleden Hall Gleden Street. Bradford Road Manchester in
the County of Lancaster Gunsmith do hereby declare the nature of my invention
for "IMPROVEMENTS IN APPARATUS FOR WARMING RAILWAY CARRIAGES AND FOR
MELTING AND CLEARING AWAY' SNOW LYING UPON A RAILWAY and in what
manner the same is to be performed to be particularly described and ascertained in
and by the following statement:-
"
In the Specification of a former patent granted to me N° 3503 in the year 1878
I described apparatus for warming railway carriages by means of air heated by
being passed through a coil of pipe placed within the smoke box of the locomotive
engine. Each carriage was provided with a pipe which passed in a zig-zag
direction beneath the seats of each compartment and where it passed across. the
doorway or passage between the two seats of a compartment it was carried down
below the floor level. The ends of the pipe on one carriage were coupled to the
ends of the pipe on the adjoining carriage and the foremost end of the pipe on the
front carriage was coupled to a pipe leading to one end of the above mentioned
coil whilst the other end of the coil had fitted to it a trumpet mouth facing
forwards in front of the engine so that when the train was running a current of
air was maintained through the coil and through the pipe on each carriage.
According to my present invention I arrange the apparatus in the manner
represented on the annexed drawings.
Figure 1 is a side elevation of a locomotive and tender with my apparatus
applied.
Figure 2 is a sectional plan of the locomotive and tender.
Figure 3 is an end elevation partly in section of a portion of the locomotive.
Figure 4 is a sectional elevation of one of the carriages and Figure 5 is a plan of
the same.
'
In order that the ends of the pipe on one carriage may be coupled to the ends of
the pipe on the adjoining carriages whether the carriage be placed with one end
foremost or the other I now form the pipe a at each end of each carriage with two
branches a¹ a projecting from it one projecting out from the end of the carriage
at a short distance from one of its sides and the other at the end of the Carriage
at a short distance from the other of its sides-so that whichever end of the
carriage may be foremost the projecting ends of the pipes will always be opposite
to similar projecting ends of pipe on the adjoining carriage and can be coupled to
them by a screw or bayonet coupling b or otherwise.
In order also to more effectually warm the air before passing it through the pipes
on the carriages I not only cause it to pass through a coil of pipe c in the smoke
box but also lead the pipe & which passes from the outlet end of the coil c through
the boiler of the engine,

In order also to more effectually maintain a current of air through the coil and
the pipe passing from it I mount a small fan or blower e on some portion of the
engine and drive it from one of the axles as the drawing indicates so that it may
deliver a continuous current of air to the coil-Or the fan might be driven by a
small donkey engine so as to maintain a continuous stream of air through the pipe
whether the train be running or stationary. I also provide means for enabling the
stream of heated air passing from the coil to be directed in a jet against any snow
by which the railway may be obstructed. The jet fI mount upon a universal
joint fat the front end of the engine so that it may be turned in any direction
desired.
In this way
I am able to utilize the heated air for melting and removing snow
whenever it is required to do so whilst at other times the passage of air through
this jet would be prevented by a stop valve.
Either the same fan might be used for forcing a stream of air through the coil at
the times when the carriages are to be warmed and also at the times when snow is
to be melted or a separate fan g might be used at the times when it is desired to
direct a stream of heated air against snow the fan being then caused to deliver a
stream of air to the rear end of the pipe d passing through the boiler so that the
air may first pass through this pipe and then through the coil c, before issuing
from the jet f The drawing represents a donkey engine h driving the fan g.. i is
a stop valve closing the connection with the pipe a in the train when the jet f is
in use.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. Providing the circulating pipes a passing through the carriages each with two
coupling branches a¹ à¹at each end.
2. The combination consisting of the circulating pipes a, the heating coil c in
the smoke box and the pipe. d passing through the boiler whereby the air is more
effectually heated.
*0
3. The combination consisting of the circulating pipes a, the pipes in which the
air is heated and the fan or blower by which the air is circulated through the
said pipes.

4. The combination consisting of the pipes in which the air is heated, the fan or
blower by which it is propelled through the pipes and the jet at the front of the
locomotive by which the air may be directed against snow.
5. Apparatus substantially as herein described and represented by the annexed
drawings for warming railway carriages and for melting and clearing away snow
lying upon a railway.
