PROVISIONAL SPECIFICATION.
Improved Means for Signalling on Railways in Foggy or Snowy
Weather.
I JOHN FAITHFULL OULTRAM of 61, King Street, Whittington Moor,
Chesterfield Gentleman, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improved means for signalling on railways during the
prevalence of foggy or snowy weather and consists in arranging along the per-
manent ways in proximity to the distance and home signals plates or rails actuated
by the ordinary signal levers and operating an arm furnished with a roller and fixed
near the steps on each side of a locomotive engine, this arm sounding a fog horn or
whistle. In carrying my invention into practice I mount on a horizontal axis
secured to any convenient part of the steps of a locomotive engine and on each side
of the same a boss or hub piece furnished with four arms, the lowermost of which
carries a roller; while the uppermost formed in one piece with the latter and
preferably in a straight line therewith is connected to a spring lever. The latter
actuates by means of a number of crank levers a fog horn fixed on any suitable
part of the locomotive. The third arm of the boss or hub is perforated and passes
over a link fixed to the side of the locomotive engine and upon which a spiral
spring is coiled, while the fourth arm carries a pin capable of moving to and fro in
the slot of a guide likewise fixed to the side of the locomotive engine and connected'
to the end of a hand lever furnished with one or more notches whereby it is held in
position with the aid of a suitable catch fixed to the side of the engine. In the
permanent way and on each side of the rails of each rail track I arrange opposite
the home and distant signals a horizontal rail or plate having inclined or shanting
ends and carried on wheels whereby it can be moved by the ordinary signal lever
with the aid of a chain and a pulley in proximity to or away from the rails
according as the signal is set at danger or not and a fog horn on a passing
locomotive is to be sounded or not; this rail or plate thus acting or not on the
roller carrying arm of the mechanism above described.

.Improved Means for Signalling on Railways in Foggy or Snowy
Weather.
I JOHN FAITHFULL OULTRAM of 61 King Street, Whittington Moor Chester-
field, Gentleman, 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:-
This invention relates to improved means for signalling on railways during the
prevalence of foggy or snowy weather and consists in arranging along the per-
manent way, in proximity to the distance and home signals, plates or rails actuated
by the ordinary signal levers. These plates or rails actuate a pivoted arm or lever
furnished with a roller and carried by the locomotive near its rear end, there being
one upon each side thereof, the motion of this arm or lever sounding a whistle or
fog-horn upon the engine.
And in order that my invention may be more fully understood I will proceed to
describe the same with reference to the accompanying sheet of drawings in which
гр.

page_text: Fig. 1 is a side elevation of the rear part of a locomotive with my improved
apparatus applied thereto, the latter being represented as having just been brought
into contact with one of the said plates or rails, and, Fig. 2 is a plan of one of the
said plates or rails and a portion of the permanent way.

Fig. 3 is an enlarged view of my improved apparatus carried by the locomotive.
a represents the locomotive and b the whistle or fog-horn operating arm or lever,
pivoted one on each side of the said locomotive. c is a roller carried by the lower
end of 'such arm or lever and which bears against the plates or rails when the
latter are brought into position by the signalman for operating the whistle or fog-
horn. These plates or rails are supported on wheels or rollers g bearing upon i
fixed plates p and are. curved or inclined downwards at each end. They are each
connected with the ordinary signal lever by means of a chain passing over a.
pulley so as to be operated thereby. Each plateror rail r is placed opposite the
ordinary signal post.t and parallel with the railway line, and when the signalman
operates his signal he at the same time slackens. the connection thus permitting
the plate or rail r to be drawn nearer to the permanent way a by means of a cord
or chain, u passing over a pulley and attached to a weight w, the plate or rail.r
being stopped a certain, distance from the line aby means of projecting plates y.
Should. it not be required: to operate the whistle or fog-horn on the engine the
lower, end of the arm or lever bis raised. sufficiently high so as not to come in
contact with, the plate or rail by means of a handle and rod d furnished with a
notch d' for supporting it in its raised position by means of a catch or plate d
The whistle e or fog-horn on the engine is operated by means of a rod f connected
to the other end of the arm or lever b, the upper end of this rod being connected.
by means of levers and rods as shown to the operating spindle of the whistle. The
construction of the arm or lever b is shown more clearly in Fig. 3. in which g is a
centre piece or hub through which passes the pivot or pin g¹.
The piece,g is formed with an extension h perforated so as, to slide freely over
the curved arm i fixed to the frame of the engine. This arm i is provided with a
coiled spring. bearing against the extension for the purpose of keeping the arm
or lever 6 in its lowermost position. k is also another arm or extension furnished.
with a pin k., The lower end of the rod d'is formed with a curved slotted piece or
link into the slot of which enters the pink whereby the lever b is. lifted, when
the rod d is raised clear of the plates or rails as shown in dotted lines, the spring i
forcing the said lever down again when the, rod d is lowered, the, slotted piece or
link allowing the lever. to rise or fall as its roller c passes over the plates or
rails r. As the roller'c'passes over the said plates or rails the whistle or gong is
sounded by the consequent drawing down of the rod f the signal or alarm ceasing
as soon as the 'roller leaves the other end of the plate or rail the duration of such
signal depending upon the length of the said plates or rails the spring m preventing
the lever band roller e descending beyond a certain distance.
Having now fully described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. In apparatus for signalling on railways the combination with the 'plates or
rails provided with rollers g and operated by the ordinary signal lever, of the
pivoted arm or lever b carried by the engine, the handle and rod 'd for bringing the
same into or raising it out of action, and the alarm operating rod f; substantially as
described and shown in the drawings.'

2. The improved signalling" apparatus substantially as described and for the
purpose set forth.
