Improvements in Means for Signalling and Stopping Trains on
Railways.
I, JOHN WILLIAM JUDGE, Paper Mills, Ingrow, Keighley, Yorkshire, Paper-
maker, do hereby declare the.nature of this invention to be as follows:-
.
This invention'has for its object the novel combination of certain mechanism and
the mounting of it to a locomotive engine in such a manner that it may be cleared
or set for action while the train is in motion, and when set and approaching a signal
placed at danger, the apparatus to be operated so as to open a tap for sounding the
engine whistle and to automatically operate the lever and valve of the air pipe of
the brake apparatus, thereby warning the driver of danger and bringing the engine
to a stand without the aid of the driver or stoker.
In carrying out my object I mount in a convenient position a shaft upon which is
secured a weighted pulley, connected in a suitable manner to the rod for operating
the signal, so that, when the latter is actuated, the pulley and shaft are operated
also.
On the said shaft is an arm which, when the signal is at danger is in a position
for supporting one end of a plate, in the position that the upper surface is inclined,
and on lowering the signal, the shaft is operated in the direction for lowering the
before mentioned plate.
To some portion of the engine frame is fitted a lever projecting towards the
ground, the bottom end having a pulley mounted thereto and the top extended on
each side of the supporting or fulcrum pin. Resting upon the extended top of the
lever, is another lever connected by a series of levers and rods to an upright bar
passing through the foot plate of the engine, and to which connections are made, so
that when the bar is actuated in an upward direction, the whistle handle and valve
lever of air pipe are both raised.
When the signal is set at danger against the engine, the plate is raised, and on
the pulley at end of lever passing over plate, it is operated on its fulcrum pin
and the motion conveyed through the connections to the upright bar, thereby
operating the same such a distance as will automatically open the whistle tap and
raise the valve lever of air pipe, by which the whistle is sounded and the brake
applied, thus automatically stopping the engine without the aid of the driver or
stoker.

Improvements in Means for Signalling and Stopping Trains on
Railways.
I, JOHN WILLIAM. JUDGE, of Paper Mill, Ingrow, Keighley, in the County of
York, Paper Maker, 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 has for its object, the automatic stoppage of locomotive engines
by a novel combination of mechanism, mounted on a locomotive, or on the tender of
same in such a manner that, a portion of the operating mechanism, may be, moved
clear away, or into such position while the train is in motion that, on the engine

page_text: approaching a signal placed at danger, for the apparatus to be actuated and auto-
matically open a tap for sounding the engine whistle, thereby warning the driver of
danger and at the same time bringing the engine to a stand without the aid of the
driver or stoker, by the automatic operation of a lever and the opening of a valve
in connection with the air pipe of the vacuum brake apparatus.
In order to explain my invention in detail, reference is made to the accompanying
drawing representing a diagramatical view of such portions of a locomotive engine
and signalling apparatus as are required for explaining my invention which is added
thereto.
The rails for carrying the locomotive and train are laid and supported by
sleepers as hitherto, and to one of the sleepers A, or other suitable support is
mounted a shaft B. upon which is secured a pulley C, shown on the part A' of
sleeper A which is in one continuous length, but is shown detached therefrom for more
clearly illustrating the invention. This pulley has a chain D. attached thereto, one
end of which is provided with a weight W, and the other connected to a rod E
coupled to the rod or chain F in connection with the signal G, thus by connecting
the shaft B. to the signal operating chains or rods F in the manner described, the
pulley C and shaft B are also operated.
On the said shaft B is secured an arm H. which when the signal G is in the
position shown by dotted lines indicating danger, the arm H will be in a per-
pendicular position and thereby support one end of a plate J. raising it to the
position shown by dotted lines, and when the signal G is lowered, the plate J is
lowered also.
To some convenient portion of the engine frame, is fitted a bracket Y projecting
towards the ground, and to which is mounted an arm K supported by a stud at K₁
passing through the arm Y and through a slot hole in the arm K which is further
supported by passing through a slot hole cut in the frame M which is attracted to
the lever N secured to the shaft O, supported by brackets attached to the engine
frame in any convenient manner.
The lever N rests upon the extended portion at the top of arm K, and is held
thereon by a weight W₁ attached to end of lever, and to the before mentioned shaft
is secured another lever P. connected by a rod Q to a bell crank lever R. to the
other arm R¹ of which is coupled an upright bar S passing through the foot plate
of engine. To the said upright bar is secured an extension or arm in any convenient
place such as at T. the arm projecting from the upright towards the handle lever of
the engine whistle, which, when the upright bar $ is raised in the manner as before
described, causes the said arm to come in contact with the handle lever of the
whistle, and thereby opperate the handle lever in the direction for opening the
whistle tap, thus allowing steam to flow to the whistle and thereby audibly calling
the attention of the driver to the position of the signal.
When the signal G is against the driver, that is at danger, in the position shown
by dotted lines, the end of the plate J is raised to the position shown by dotted
lines in the manner as before described, and on the pulley L passing over and in
contact therewith, the arm K is raised, by which the lever N is raised also, thereby
operating the shaft O and the lever P secured thereto which operates the rod
and bell crank lever R, thereby raising the upright bar S such a distance that, the
whistle handle lever is actuated and the whistle sounded by the automatic opening
of the tap; and by a projection on the said upright bar, a valve or tap handle may
be raised, by which air is admitted to the pipes of the vacuum brake, thus applying
the brake blocks and thereby bringing the engine to a stand without the aid of the
driver or stoker.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same may be performed, I declare that what I
claim is :-
1. The combination with the rod or chain for operating the signal G, of a shaft B,
arm Hand plate I fou the
CL

page_text: 2. The combination with the plate J of an arm K operated by the said plate by
which the handles of the engine whistle and air brake pipe valves or taps are
actuated either separately or in combination substantially in the manner as set
forth.
