A horizontal lever is pivotted under the floor of the locomotive. From the outer
end of this lever a vertical rod rises to the valves of a steam cylinder fixed on the end
of the boiler. From the piston of the steam cylinder a vertical rod descends into an
air cylinder either on, or below, the floor of the locomotive. This air cylinder is
connected with the air pipe of the Westinghouse Brake (or with the cylinder of the
Vacuum Brake) by means of another pipe, and the piston rod in it (i.e. the air
cylinder) which has no piston on it, but fits tightly into the air cylinder, and has an
oblong hole in it, is so placed that it covers the mouth of the pipe from the Westing-
house Brake air pipe, or from the Vacuum Brake cylinder, until the vertical rod is
driven down by the action of the steam in the steam cylinder, when, the mouth of the
pipe to the air cylinder being uncovered, the compressed air of the Westinghouse
Brake passes through the hole in the vertical rod, and out at a port at the foot of the
air cylinder, (or in the case of the Vacuum Brake, the air passes through the port at
the foot of the cylinder up through the hole in the vertical rod and through the pipe
to the cylinder of the Vacuum Brake) in either case at once applying the brake.
Above the steam cylinder, the piston rod is connected to a crank which again has a
link connected to it, and a regulator handle, which regulator handle works a set of

on
the ordinary connecting rods or links and cranks, which again work an extra valve
which is placed on the steam valve and is termed the "Emergency Valve." The
vertical connecting rod from the horizontal lever, has a movable stud on it, and passes
through a lock fixed on the end of the boiler. The bolt of the lock is connected with
a link &c. with the ordinary regulator handle of the steam valve. When the steam is
off" the bolt is back, and the vertical rod can freely pass up and down through the
lock. But when the steam is
the bolt is thrown forward about half an inch,
& should the vertical rod be drawn down, the stud will be pressed back by the bolt,
until it passes it when it will be thrown underneath the bolt by a spring, and thus
prevent the vertical_rod from rising, until the steam is shut off by the ordinary
regulator handle. From the "Emergency Valve" regulator handle, or from the
crank above the steam cylinder, a cord is led over pulleys to work the steam whistle
handle. If a special steam whistle is desired the piston rod of the steam cylinder
is carried up past the crank, and made to operate a valve in the steam pipe which
supplies the special steam whistle.

OPERATION OF THE APPARATUS.
When the inner end of the horizontal lever is raised, it depresses the vertical rod
attached to the outer end of it, and this opens the valves of the steam cylinder. The
steam rushes into the latter, and pushes down the piston and piston rod. This draws
round the mechanism for operating the "Emergency Valve " & shuts it. By means
of the cord it also draws the whistle handle, and sounds the steam whistle. At the
same time the vertical piston rod in the air cylinder being pushed down, till the mouth
of the pipe leading to it is uncovered, air passes through the cylinder & pipe and
applies the Westinghouse or Vacuum Brake as described before (see top of page 2).
The whole apparatus is locked by means of the lock before described (see middle of
page 2) and cannot be reversed till the steam has been shut off by the ordinary
regulator handle.
Suitable handles are provided for reversing the apparatus in this and the other
four methods.
METHOD II. BY THE USE OF COMPRESSED AIR.
An air cylinder is fixed on or below the floor of the Locomotive & is connected
with a pipe to the air pipe of the Westinghouse Brake. The horizontal lever of
Method No. I is connected at the outer end to the valves of the air cylinder. The
air cylinder has a piston and a vertical piston, (or connecting) rod, which latter (with
a movable stud on it) passing through the lock described in Method No. I (see middle
of page 2) rises to such a height as is required for it to work a crank, which crank
by means of a link, works the regulator handle, and other links &c. &c. of the "Emer-
gency Valve" all as described in Method No. I see (page No. 2). A cord is led over
pullies either from the regulator handle of the "Emergency Valve," or from the
crank above referred to, to the steam whistle handle. If a special steam whistle is
desired, the vertical piston rod (or connecting rod) is continued past the crank and
made to operate a valvo in the steam pipe which supplies the special steam whistle, as
in Method No. I.
OPERATION OF THE APPARATUS.
When the inner end of the horizontal lever is raised it opens the valves of the
air cylinder. The compressed air rushes into the air cylinder and drives down the
piston, & thus by means of the intermediate mechanism described above closes.
the " Emergency Valve," and sounds the whistle. When the piston rod has reached
the bottom of the cylinder the compressed air escapes through at a port & thus
applies the brake. At the same time the apparatus locked by means of the lock
described in Method No. I. (see middle of page 2) operating on the vertical piston,
(a connecting) rad

page_text: METHOD V. BY THE USE OF ELECTRICITY OR MAGNETISM.
This arrangement is also similar to No. II. For direct action the cylinder & piston
in it are dispensed with and the air cylinder &c. of No. I Method are used instead. A
suitable magnetic or other suitable battery is placed in a convenient position and when
the horizontal lever is operated it discharges the battery and forces down the piston
rod thus applying the whole apparatus.
DETAILS OF THE ABOVE METHOD AND OF ITS OPERATION.
The battery is placed below the floor of the Locomotive, or of the tender, and a
pendant bracket is hung from the floor in proximity to the horizontal lever which
is pivotted below the floor. This bracket has upper & lower contact plates on it,
and also a suitable switch pivotted on it. The handle of the switch will be suitably
connected with the end of the horizontal lever so that when the lever rises or falls,
the arms of the switch (whose normal position is one of slope clear of the contact
plates) will be thrown backwards & forwards, and the contact plates on them will
come into contact with the contact plates of the pendant bracket and thus complete
the circuit. A conductor wire will be led from cach end (or pole) of the battery to
a powerful coil, or spring, electro magnet, in such a way that when the switch is in
its normal or sloping position, the current is broken, but when the lever is raised or
depressed the switch is operated & the current completed & of course the magnet

page_text: magnetized. The position of the magnet will vary according to whether it is desired
to make it work the apparatus directly or indirectly. If the former it is placed in
such a position that when magnetized it will draw down the vertical rod, itself, & this
sounds the whistle, shuts off the steam and applies the brake. If the latter it is
placed a little above the valves; of the steam cylinder of Method No. I (see page No. 1)
or of the air cylinder of Methods Nos. II & III (see page 3), and when magnetized
draws the valves to it and thus sets the apparatus in motion by the steam or air,
and sounds the whistle shuts off the steam & applies the brake.
DI FCIAL STEADI WHISTLE.
This may be described as a double whistle, a smaller one on the top of a larger
one. The steam passes by a pipe up through the under part to the upper part.
The under part & the upper part being of different sizes & being simultaneously
sounded will produce a peculiar sound which will be easily recognized.
