Street, Liverpool, in the County of Lancaster. "IMPROVEMENTS IN AND APPER-
TAINING TO ELECTRIC SIGNALLING APPARATUS ON RAILWAYS." [A communication
from abroad by Charles Lecoq, of Auch, in the Republic of France, Printer.]
To an ordinary telegraph post is fixed a metallic wire starting from the bottom
and mounting to a height of four feet, where it joins on to one of the stops of the
electric apparatus, and is put in contact with the commutator directing the positive
or negative current as required. From the commutator goes out the wire, which
mounts to the level of the special line wire to which it is tied, to take the portion
of electric current requisite for putting the signals in movement when required.
Six inches beyond is fixed the box or bracket which supports the electro-magnet,
and which is surmounted by the arc, which is provided with an archimedean screw
or helix, which the electric current puts in motion. Through this movement the
signals are put in action. To the head of the helix is hooked the swivel fixed at
the extremity of the strap or tension coupling, which by a pull produces the move-
ment of the signals. On the side of the post and at a level with the upper part of
the electric apparatus is fixed the lamp bracket, the upper extremity of which
enters into the square socket of the lamp bottom.
The lamp is provided with double transparent semaphore, one plate of the sema-
phore being on each side of the lamp.
On top of the post is fixed the signal, showing two faces (for up and down line
respectively), when the current has brought it into action. When these signals
have been actuated they can immediately afterwards be put back into their normal
position by the locked handle, which signal posts of this description always carry.

page_text: This operation can never be made before the order has been received, the signals
having to undergo the entire process before they can become free.
The application of the above-mentioned signals does not necessitate the creation of
any fresh employment, and the present staff is not disarranged by the installation
of this system.
