page_text: I, WILLIAM FREEBURY of 139 High Street Harlesden in the County of Middlesex,
Cabinet Maker, do hereby declare the nature of this invention to be as follows:-
The
This invention relates to the construction and means for operating signals such as
are usually employed upon railways, the invention being particularly useful for what
are known as distant signals but being also applicable to those near at hand.
invention may be employed alone or in combination with the invention described by
me in my specification No. 14402 of 1886, or with the ordinary point or crossing
mechanism.
The invention consists of the arrangement and combination of parts as hereinafter
indicated.
The signals are pivoted upon the ordinary signal posts and are actuated by means
of a connecting rod excentrically attached to a drum or a wheel around which the
actuating wires or cords pass, or to make the motion more positive and accurate the
periphery of said wheels or discs may be toothed and carry linked chains adapted to
engage therewith and attached to the wires or cords from the signal or point lever.
Two or
more signals may be operated from the one lever by the same set of wires
or cords and these may also be used for actuating the points or crossings by connecting
the cords or wires therewith or for operating the pivoted rail section or lever described
in my said prior specification.
The signal or point lever may also consist of a drum or a wheel provided with teeth,
or an ordinary lever may be used, the wires or connections being attached upon either
side of the pivoted point thereof.
WILLIAM FREEBURY.

and
is a plan view of same.
Fig. 3 represents an end elevation of the parts in position.
Fig. represents a side view of an engine with the signal levers attached thereto,
Figure 5 is a plan of the railway beneath.
The lever A is secured to the shaft of drum or sprocket wheel B, around
which, pass the cords b, b, to drum or wheel B', secured to the shaft of
which is the arm for operating the rod 62 attached to the distance
signal C.
The lower end of lever A operates rod a, which through bell crank
lever a and flexible connection a² is adapted to move the pivoted rail section D into
the position shown by dotted lines in Fig. 2, at the same time that arm & drops the
distance signal C and shows "line clear." When lever A is brought into the position
shown in Figs. 1 and 2, signal ( will bo at "danger" and spring will have forced
the rail section D (which is pivotted at d¹) into the position shown by full lines in
Fig. 2. Should a train now pass as against the signal section I would be forced out
by the flange of the wheels and by means of rode and connected levers bell E would
be sounded thus audibly calling attention to the fact that the signal was at "danger"-Or
in lieu of having the audible signal upon the side of the line pivotted section D may
be formed with a segmentally curved head as shown in Figs. 4 and 5, which when
signal C is at "danger" will by means of connecting rods a, a², be drawn into the line
of travel of lever F pivotted at and lift same when the engine passes and thus through
rod and bell crank leverf open whistle G, or if desired the curved face of pivotted
section D may be placed npon the side so as to give a side instead of a lifting move-
ment to the rod connected to the whistle (and carried by the engine) which would
then be pivotted so as to move in the horizontal instead of the vertical plane. When
the signals are to bo operated from a distant signal box drum or wheel B may be

page_text: actuated by a connecting rod eccentrically connected thereto. Said connecting rod
may if desired form part of the ordinary point and crossing mechanism so that the
signals and points will be worked in unison.
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 :-
1st In railway signals the combination of two or more drums or wheels and
connecting cords and lovers adapted to operate the distance signals and at the same
time to set in or out of line the lever or part adapted to operate the audible signals
should the engine or train pass, substantially as set forth.
2nd In railway signals the combination with the actuating device of the distance
signal of a movable section adapted to operate an audible signal on the passage of a
train when the signal is at danger, substantially as set forth.
3rd The general arrangement and combination of parts forming the improvements
in railway signals substantially as herein before described.
Dated this l5th day of October 1887.
