SAFETY IN TRAVELLING.
A New Signal that Seems TO Make Rail-
road Accidents impossible.

A New signal that seems to Make Rail-
road Accidents impossible.
Richard M. Jordan of this city has been
elected President of company that is
promoting the introduction of new rail
road signal that will probably, in time,
supplant all the signal systems employed
on the various railroads of the country
The company is known as the Railway Cab
Electric Signal Company. Speaking gem
orally, the invention Is designed to ring an
alarm in the locomotive engineers cab,
whenever his locomotive approaches q
place of danger. 1t obviates the danger
resulting from dependence upon careless
or color blind engineers, or upon sleepy or
careless nignal settlers, or inattentive
switch and bridge tenders. BY simple
electric continuance, which works automat
ically, an open draw or an open switch
ahead is made known to the engineer by
the continuous ringing of bell in his cab.
The principle is as follows: The locomo-
tive is provided with an electric generator.
or Dynamo machine.
The two poles of the Dynamo terminate
by means of wires one to the body of the
locomotive, and one to the tender frame of
the same, both having metallic contact
with the rails by means of their wheels.
These two points, or terminals formed by
the wheels, must be insulated from one
another; SO that when on the rail, the
wheels of the locomotive and the wheels of
the tender are only connected together
electrically by means of the rail- There is
thus closed circuit in action by means of
the Dynamo, locomotive, tender and the
rail. This closed circuit passes through a
magnet in the cab which holds an armature
to itself. When this circuit is interrupted,
or opened, the armature leaves its magnet,
and IN so doing, by lever action, operates
the bell IN the cab. The interruption or
opening of the circuit to cause the arma-
ture to leave its magnet, is made by insu-
latlng two abutting rails, one from another,
so that when the locomotive wheels on one
rail, and the tender wheel on the AUDITING
rail, the insulation between the rails will
cause the circuit between the wheels to be
interrupted or opened, when the conse-
quent signal is given. From the insulated
abutting rails, separate wires are led, to
join which would destroy their insulated
condition. These wires are led any given
distance for any signal purpose, terminal
ing at a switch-a drawbridge-a station
at block points-or any other point from
which locomotive may be signaled, or
which locomotive may signal. By suita-
BILE parts controlled by magnets, so as to
contact, and not to contact, these wires are
opened and closed-as the case may be-
at the points where they terminate.
If a switch is closed the wires are closed
if switch is open the wires are open.
Then when the insulated joints Of the wires
Interrupts before shown-the current
through the rail from the locomotive to the
tender, such current must follow the wires
leading from the two rails. Thus, funda-
mentally, if the two wires are closed at any
remote signaling point, the locomotive cir
cult will remain closed when passing the
insulated joint where these wires join the
rail. If the two wires are open at any
remote signaling point, the locomotive cir
cult in the same position will be opened,
and the signal sounded. Thus at switch,
bridge. station, block, or any point, danger
means open circuit, and signal to locomo-
tive, while safety means closed circuit, and
no signal. The locomotive in motion forms
moving closed circuit on the rail, which
is continued closed, or it is opened, as there
may be safety or danger in It's path.
