We, HENRY WILLIAMS of Albert Drive Crosshill Glasgow, Engineer and
'ANDREW WILLIAMSON of Park Circus Place Glasgow Accountant do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in railway signalling apparatus and has
for its object to provide means whereby a signal can only be effectually worked
and controlled from two or more cabins or independent places whilst at the same
time in the event of a connecting rod or any other connection whatever breaking
or becoming deranged, the signal will in all cases rise or go to danger or in other
words the heavy balance arm upon the semaphore will return the same to the
position indicating danger.
In carrying the said invention into practice we secure within suitable bearings
upon a framing attached to the signal post a sliding rod or bar which is attached
by means of a suitable connecting or signal rod to the semaphore arm normally
held in the position of danger by means of the heavy balance herein before referred
to and also returned to such position thereby when the signal rod is released. To
this sliding rod is pivoted a link or crescent-shaped piece whose extremities
occupy a position above the ordinary weighted levers which are designed to be
worked from the separate cabins or places and which in their movement (by
means of the signal wire or other connection) are designed to operate as follows
that is to say:-When either one of the weighted signal levers is worked from a
cabin it will act upon one end of such link or crescent-shaped piece and will raise
such end (without however affecting the position of the semaphore arm) so that
the other end of the said piece will be depressed so as to occupy a position above
the other weighted lever or levers (on the signal post) designed to be actuated
from another cabin or cabins. When however such other lever or levers is or are
actuated from some other cabin or place the link or crescent-shaped piece will with
the sliding rod be bodily raised so as to push the semaphore arm off to a position
of caution or all right. If then the signal wire or other connection should break
or become deranged such link or crescent-shaped piece will be left free so that
the semaphore arm will be immediately returned to danger by the descent of its
weighted or heavily balanced arm.
In some cases instead of arranging the crescent or other shaped piece or part
above the aforesaid weighted levers we modify the arrangement by connecting
such levers by a chain preferably of flat construction and secured to such levers
by a pin shackle and eye or in any other suitable manner. This chain is adapted
to act upon a sleeve or thimble upon a stud secured to the sliding bar connected

page_text: with the semaphore-arm so as to raise such bar when both weighted levers are
raised in other words such chain is so arranged that when one lever only is raised
the said chain will be simply lifted at one end without effecting any movement of
the sliding bar but when the second lever to which such chain is attached is
subsequently raised the chain will act upon the thimble or sleeve and thus lift the
aforesaid sliding bar to bring the semaphore arm to a position of safety or caution
whilst at the same time permitting the arm to go to danger in case of any breakage
or derangement of the connections.

We, HENRY WILLIAMS of Albert Drive, Crosshill Glasgow, Engineer and
ANDREW WILLIAMSON of Park Circus Place Glasgow Accountant do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement reference being had to the accompanying drawing forming a part of this
Specification:-
This invention relates to improvements in railway signalling apparatus and has
for its object to provide means whereby a sigual can only be effectually worked
and controlled from two or more cabins or independent places whilst at the same
time in the event of a connecting rod or any other connection whatsoever breaking
or becoming deranged the signal will in all cases rise or go to "danger" or in
other words the heavy balance arm upon the semaphore will be free to return the
same to the position indicating danger.
In the accompanying drawing we have shewn two-arrangements of devices
whereby we effect the object of our invention. In this drawing
Figure 1 is a face view and
Figure 2 a side view of one-arrangement-of such devices and
Figures 3-and-4-are-similar-views-of the-other-arrangement-of-such-devices.
Figure 3 is an elevation of a signal post drawn to a reduced scale shewing the
devices represented-in-Figures 3 and 4 in position thereon the balance or weighted
levers being illustrated as raised and the semaphore arm therefore "pushed off."
Like letters indicate the same parts throughout the drawing.
a represents the signal post proper and 6 the semaphore arm thereof. c is the
signal arm operating rod. d d are the ordinary balance levers.
In carrying our invention into practice as illustrated in Figures 1 and 2 of the
drawing we secure within suitable bearings el upon a framing e, attached to the
signal post, a sliding rod or bar f which is united by means of the connecting or
signal rod c with the semaphore arm b. This arm is normally held in the position
indicating danger by means of the heavy balance herein before referred to and is
also returned to such position thereby when the signal rod is released To-the
rod-f-we-pivot-at-fl-a-piece-i-whose extremities or arms-occupy-a-position above
the-weighted-levers-d-d-which-are-designed-to-be-worked-from-the-separate cabins
or places and which in their movement (by means of the signal wire or other
connection)-are-designed to operate as follows-that-is-to-say: When either-one
of the weighted levers-d-is-worked or "pulled off" from-a-cabin-it-will-aet-upon
one-arm-or-end-of-such pivoted-piece-i-and will raise-the-said-arm-or-end-(without
however-affeeting the position of the semaphore-arm-6) so that the other arm or
end-of-this-piece-i--will--be--depressed and--occupy a position above the other
weighted-lever-or-levers-ton-the-signal-post)-designed to be actuated from another
cabin-er-eabins. When however such other lever or levers-d-is-or-are-nctuated
from some other cabin or place the piece-i-with-the-rod-or-bar-f-will be jointly
raised-so-as-to push the semaphore arm off to a position indicating "caution" or

page_text: " all right." If then the signal wire or other connection should break or become
deranged-such-piece-i-and-the red-or-bar-f-will be left free so that the-semaphore
arm will be immediately returned to danger by the descent of its weighted or
heavily balanced-arm.
The-pivoted-piece-i-may be constructed of the shape-shewn in the drawing or
more-crescent-shaped or of any other suitable form so long as the main feature of
our-invention-is-attainable namely that on one of the levers-d-being "pulled off."
it will turn the piece-i-upon its pivot without raising the rod f and will bring
such-piece-into-such-a-position that-on-the-other lever-d-being pulled-off"-it-will
raise the said piece i together with the-rod-or-bar-f so that the arm-b-is "pushed
off"-through-the-rod-c.
In the modified arrangement illustrated in Figures 3 to 5 instead of employing
a-piece-i-above We connect the weighted levers d we connect-such levers by a
chain preferably of flat construction and secured to such levers by a pin shackle
and eye or in any other suitable manner. This chain is adapted to act upon a
sleeve or thimble k upon a stud ¹ secured to the sliding bar fso as to raise such
bar when both of the weighted levers d are raised; in other words such chain is so
arranged that when one lever only is "pulled off" the said chain will be simply
lifted at one end without effecting any movement of the sliding barf but when
the second lever to which such chain is attached is subsequently "pulled off" the
chain will act upon the thimble or sleeve k and thus lift the said barf so as to
push off" or bring the semaphore arm b to a position indicating "safety" or
"caution" whilst at the same time permitting the said arm to go to "danger" in
case of any breakage or derangement of the connections.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed, we declare that what
we claim is:-
First. The--combination with a railway signal-adapted to be--operated and
controlled-from-independent points or places, of a piece-pivoted-to-a-sliding-rod-or
bar-(connected-with the semaphore-arm) and co-arranged relatively to the balance
levers that on one lever being "pulled off" such piece will be-turned-upon its
pivot-without actuating the semaphore arm and be brought into such-a-position
that on the other lever being "pulled off" such piece and the sliding-rod-or-bar
will be jointly-raised so as to "push-off"-the-arm to a position of "caution" or
safety whilst at the same time such-arm will be free to go to danger in
the-event-of breakage of or derangement in connections-all substantially as herein
set-forth.
Second. The combination with the balance levers d of a railway signal such as
is herein described, of the chain j adapted to operate in combination with the
thimble or sleeve k upon the bar or rod f all substantially as herein set forth and
for the purposes specified.

We, HENRY WILLIAMS of Albert Drive, Crosshill Glasgow, Engineer and
ANDREW WILLIAMSON of Park Circus Place Glasgow Accountant do hereby

same to the position indicating danger.
In the accompanying drawing we have shewn two arrangements of devices
whereby we effect the object of our invention. In this drawing
Figure 1 is a face view and
Figure 2 a side view of one arrangement of such devices and
Figures 3 and 4 are similar views of the other arrangement of such devices.
Figure 5 is an elevation of a signal post drawn to a reduced scale shewing the
devices represented in Figures 3 and 4 in position thereon the balance or weighted
levers being illustrated as raised and the semaphore arm therefore "pushed off."
Like letters indicate the same parts throughout the drawing.
a represents the signal post proper and the semaphore arm thereof. c is the
signal arm operating rod. d d are the ordinary balance levers.
In carrying our invention into practice as illustrated in Figures 1 and 2 of the
drawing we secure within suitable bearings e' upon a framing e, attached to the
signal post, a sliding rod or bar f which is united by means of the connecting or
signal rod c with the semaphore arm b. This arm is normally held in the position
indicating danger by means of the heavy balance herein before referred to and is
also returned to such position thereby when the signal rod is released. To the
rod f we pivot at f¹ a piece i whose extremities or arms occupy a position above
the weighted levers d d which are designed to be worked from the separate cabins
or places and which in their movement (by means of the signal wire or other
connection) are designed to operate as follows that is to say:-When either one
of the weighted levers is worked or "pulled off" from a cabin it will act upon
one arm or end of such pivoted piece i and will raise the said arm or end (without
however affecting the position of the semaphore arm b) so that the other arm or
end of this piece i will be depressed and occupy a position above the other
weighted lever or levers (on the signal post) designed to be actuated from another
cabin or cabins. When however such other lever or levers d is or are actuated
from some other cabin or place the piece i with the rod or bar f will be jointly
raised so as to push the semaphore arm off to a position indicating "caution
"all right." If then the signal wire or other connection should break or become
or

page_text: deranged such piece i and the rod or bar f will be left free so that the semaphore
arm will be iminediately returned to danger by the descent of its weighted or
heavily balanced arm.
The pivoted piece may be constructed of the shape shewn in the drawing or
more crescent shaped or of any other suitable form so long as the main feature of
our invention is attainable namely that on one of the levers d being "pulled off"
it will turn the piece i upon its pivot without raising the rod f and will bring
such piece into such a position that on the other lever d being "pulled off" it will
raise the said piece i together with the rod or bar f so that the arm bis "pushed
off" through the rod c.
In the modified arrangement illustrated in Figures 3 to 5 instend of employing
a piece i above the weighted levers d we connect such levers by a chain; preferably
of flat construction and secured to such levers by a pin shackle and eye or in any
other suitable manner. This chain is adapted to act upon a sleeve or thimble /
upon a stud secured to the sliding bar f so as to raise such bar when both of
the weighted levers d are raised; in other words such chain is so arranged that
when one lever only is "pulled off" the said chain will be simply lifted at one end
without effecting any movement of the sliding barf but when the second lever to
which such chain is attached is subsequently "pulled off" the chain will act upon
the thimble or sleeve and thus lift the said bar f so as to "push off" or bring the
semaphore arm 6 to a position indicating "safety
caution" whilst at the
same time permitting the said arm to go to "danger" in case of any breakage or
derangement of the connections.

we claim is-
First. The combination with a railway signal adapted to be operated and
controlled from independent points or places, of a piece pivoted to a sliding rod or

Second. The combination with the balance levers d of a railway signal such as
is herein described, of the chain j adapted to operate in combination with the
thimble or sleeve k upon the bar or rod f all substantially as herein set forth and
