PROVISIONAL SPECIFICATION.
An Improved Means of Railway Signalling by Detonators, to be Used
Chiefly During Foggy Weather.
FRANK STUART MURRAY, 11, Cunningham Place, St. John's Wood, London,
NW, Artist, do hereby declare the nature of thus invention to be as follows:-
Such additions as may be necessary would be made to the gear attached to the
signals, so that the action of setting them also operates upon a movable piece or
pieces of metal or other material in close proximity to the rail over or near which
the locomotive or train passes
This action takes place under all circumstances being dependent for its action
upon the levels setting the signal
This mechanical contrivance-by contact will explode a detonator carried by, &
attached to the engine or other carnage which detonator is under the control
o the engine driver or other official upon the train & is laid by him in ono or
more magazines attached to the locomotive or other carnage I likewise claim
as part of this mechanism the invention of such magazines & detonators attached
to any locomotive or other cariage for the purpose of signalling under any
condition whatever.

An Improved Means of Railway Signalling by Detonators, to be Used
Chiefly During Foggy Weather.
I, FRANK STUART MURRAY, 11, Cunningham Place, St John's Wood, London,
NW, Atist, do hereby declare the nature of this invention and in what mannei
the same is to be performed to be particularly described and ascertained in and
by the following statement
1
According to this invention the locomotive or other camage has upon it a
magazine containing detonators together with mechanism for delivering and
exploding the detonators such mechanism being worked by the passage of the
engine over a movable piece operated by the signal or point levers or otherwise.
Figure 1 is a plan, Figure 2 a side elevation and Figure 3 a transverse section
of the railway.
In these figures a is the ordinary rail and b an inclined rail pivotted at 61 which
when a signal is to be given is moved from the position shown in dotted lines in
Figure 1 to the position shown in full lines by means of the rod c.

page_text: Figure is a side elevation of the mechanism on the engine and Figures 5 and 6
are sections on the lines 5-5 Figure 4 and 6-6 Figure 5 d is a wheel normally
stationary but revolving when it comes upon the ail e 18 a pinion fixed to
the wheel and geaing with the wheel to which the notched disc g is fixed.
is the magazine containing detonators which when the mechanism is in motion
are canned down by the notched disc g to the pressing roll, which explodes them
Figures 7 to 10 show a modification Figure 7 is a vertical section on the
Ine 77 Figure 10 Figures 8 and 9 are vertical sections on the lines 8-8 and
9-9 Figures 7 and 10 and Figure 10 is a ho117ontal section on the line 10-10
Figure 7
In this case the wheel d 11ses and falls carrying with it the slide which is
free to work up and down in guides / The slide is slotted (as shown in Figure 8)
to receive the tiangular block m fixed to the shaft m the slot being so shaped
that each up or down movement of the slide gives a thud of a revolution to the
shaft m¹ n is a disc fixed to the shaft m³ and having in it three radial holes n'.
o is a pin fixed to the slide X and engaging with a heok pivotted on the ampl
which is fixed to the shaft q q' is a second arm fixed to the shaft q The arm 7.
18 slotted and engages with a pin on the slide which also has fixed to it a second
is the magazine having a ring of holes in it to receive the detonators
During the downward motion of the slide the pin o engages with the hook
and pulls it and the arm p' downwards turning the shatt q and causing the arm
to pull down the slider and pin² the latter pushing a detonator out of one of
the holes of the magazine into one of the holes n' in the disen the latter being
at this time stationary The tail end of the hook then comes against the fixed
incline which disengages it from the pin o is a spring plunger or fing
piu resting against the dist n and when toward the end of the downw.nd motion
of the slide the dise is revolved one of the inelines 2 on it presses back the
fing pin against its sping but when it comes to the end of and escapes from the
incline it flies inwards and explodes the detonato
Having now particularly described and ascertained the nature of my sand
invention and in what manner the same 18 to be performed, I declare that what
I claim 18:-
1 The combination of a magazine and mechanism for delivering and exploding
detonators on the locomotive or other canlage with means on the railway fo
putting the mechanism into operation
2 Means for railway signalling substantially as described and illustrated in the
diawings
