TRUVIDIONAL DI MULTICATION,
Improvements in Railway Fog-Signalling Apparatus.
JAMES RESIDE, Mechanic, Brook Street, Rastrick Brighouse, and JOHN WATSON
MILLER Oil Merchant, Cominon, Brighouse Yorks do hereby declare the nature of this
invention to be as follows:—
This invention refers to a new construction and arrangement or apparatus for
automatically placing detonators or fog signals upon Kailway lines.
In carrying out this invention I place a parallel rail to the permanent way, suitably
fixed to permit a slight lateral motion caused by the wheels of a passing train. This
rail is drawn back to the rail after a train has passed, by a counter weight.
Froin this rail is a bar (No. 1) stretching across the permanent way and to a
distance. outside sufficient to perform the duties required of it as described later on.
Upon a vertical spindle, fixed in a suitable frame, and at a suitable distance from the
rail, is a compound wheel composed of two portions; the upper being supplied with
arms attached to lugs upon the wheel. These arms are for carrying the detonators,
and laying them on the rail; the lower portion of the compound wheel having upon
the upper side a crown ratchet, also a spur ratchet, and under the spur ratchet on an
extension of the rim a number of suitably formed recesses.
From between the two wheels and working on their boss, is a lever, No. 2, long
enough to extend at about right angles across bar No. 1. Upon lever No. 2 is
hinged a pawl working in the crown ratchet. No 2 is not attached to bar No. 1 but
is suitably actuated upon by a stud in bar No. 1. No. 2 is kept in position by a
counter weight pulling in the opposite direction to bar No. 1.
Working at right angles to bar No. I is lever No. 3. It is so placed at one side
of the lower wheel us to work a pawl or clutch in the spur ratchet. No. 3 is actuated
upon by No. 1 by means of two studs.
On the other side of the under wheel is lever No. 4 suitably formed to work into
the recesses on the extension of the rim. A suitable weight is attached in order to
hold this lever in contact with the wheel.
Attached to the signal apparatus working from the signal cabin is bar No. 5 working
parallel with bar No. 1. When the signal is pulled off this bar No. 5 is also pulled,
and is so shaped that a protuberance is brought under the pawl on lever No. 2 and
puts it out of gear with the crown ratchet.
At the same time a suitable lever arrangement attached to bar No. 5 raises the arm
on which the detonator is attached from the rail. When the signal is again put on,
a suitable weight pulls bar No. 5 to its place, allowing the pawl again to get into
gear, and releasing the arm with the detonator, which falls upon the rail.
Attached to the frame work, and surrounding but not attached to the compound
wheels, is a cяse. Opposite the rail is a vertical slot. One side of the slot is vertical,
the other is cut at a suitable angle. As the arms pass the vertical side of the slot
they fall, and as the pawl drives the wheel round, the arms rise on the angular side.
The arins to which the detonators are attached inove freely in the lugs. They have
a rear extension. As the wheel carrying the arms revolves, the arms inside of the
case have a vertical position, and as they come about opposite the slot the rear
extension comes in contact with the arm of a lever, the other end of which is

page_text: weighted. This lever with counter weight is for the purpose of making the fall of the
arin with the detonator absolutely certain.
The detonators are fixed on to the end of the arms by means of a suitably shaped
strip of lead or tin.

Improvements in Railway Fog-Signalling Apparatus.
We, JAMES RESIDE, of Brook Street, Rastrick, Brighouse, in the County of York,
Mechanic, and JOHN WATSON MILLER, of the Common, Brighouse, aforesaid, Oil
Merchant, 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 refers to a new construction and arrangement of apparatus for
automatically placing detonators or fog signals upon railway lines.
In describing the invention in detail reference is made to the accompanying
drawings, and to the letters of reference marked thereon.
Fig. 1 is a plan showing a portion of the permanent way of a railway with our
improved apparatus fitted thereto.
Fig. 2 is an end view of the permanent way showing one of the chairs in section.
Fig. 3 is a plan of the apparatus fitted within a frame, the upper portion of which
is removed.
Fig. 4 is a section through line a. b.
Figs. 5 und 6 are detached details.
Fig. 7 is a section drawn to a larger scale through the upper and lower frames or
casements and the apparatus within same, with one of the detonators in position on
the rail, and
Fig 8 is a plan, the upper portion of the frame or casement is removed.
In carrying out this invention, we place parallel to one of the rails A. of the
permanent way, a short length of rail B. suitably fixed to a series of levers C. the
opposite ends of which are connected by a bar D. One of these levers C. is arranged
with an extending arm C' to which is attached a chain or the like E. passing over a
pulley F. and attached to a counter-weight G. by which the short length of rail B. is
drawn near to the rail A. of the permanent way when in its normal position.
A lever H. is suitably mounted and coupled to the short rail B. by a link J. and to
the lever H. is attached a rod K. extending across the permanent way aud coupled to
a bar L. upon which are formed stops or vertical projections L' I and I shown by
Fig. 3 for the purpose as hereinafter described.
Within a suitable frame M. is fixed a vertical spindle N. upon which is mounted a
compound wheel, composed of two portions O. and 0¹, the upper portion O. being
attached to the lower portion O' in any convenient manner. To the upper side of
the compound wheel is secured a ring P. provided with a number of lugs P¹ for
supporting the arins Q. carrying the detonators Q and to the underside of the said
compound wheel is secured a crown ratchet wheel R. by the operation of which, the
compound wheel and ring P. carrying the detonator arms Q. are rotated.
Between these two wheels is mounted on the boss of one of thein, a lever S. of such
length as to extend across the before mentioned bar L, the lever S. being kept in
contact with the vertical stop or projection I. by a weighted chain or the like T.
passing over pulley U. This lever is fitted with a hinged pawl V. by which the crown
ratchet wheel R. and attachments are rotated on the reciprocation of the bar L.

page_text: On a train passing the apparatus, the flange of the wheels passing between the
mails A. and B. force the latter in the direction of the arrow, thereby operating the
bar 1 in the same direction, thus allowing the weighted chain T. to draw the
lever S. in the same direction, as shown by arrow 2, thereby moving the hinged
pawl V. some distance over the face of the crown ratchet wheel R. When the
Banges of the wheels are clear of the rail B. it is brought back to its normal position
by the counter weight G. in the inanner as hereinbefore described, thus operating
the bar I, and by means of vertical projection L the lever S. in the opposite
direction to that shown by arrow 2, thereby rotating the crown ratchet wheel R. and
attachments to the vertical spindle N. the distance required for placing a detonator
attached to one of the arms Q. on the rail.
At right angles to the bar L. is a lever W. mounted on a fulcrum pin at W¹, one
end of the lever is prepared to engage with the teeth on the upper portion O. of the
compound wheel when the bar L. is moving in one direction, the other end of the
lever being connected by a chain or the like X. passing over pulley X1 to a
weight X. On the opposite side of the wheel is mounted another lever Y. supported
by a stud at Y and is of such length as to engage with a projection Z. on bar, the
lever is also prepared with an extension Y for engaging with the teeth of the bottom
portion 0 of the compound wheel and the lever is kept in contact with the
projection Z. by means of a weighted bell crank lever 1. The operation of these
levers W. and Y. are for locking the compound wheel by engaging therewith at the
required time, the lever W being for the purpose of preventing the compound wheel
rotating more than the distance of one tooth each time the bar L. is operated.
The bar is connected to the signal box in a manner that, when the signal is
"pulled off" the bar is pulled also. This bar is arranged with a protuberance 2;
and is brought under the hinged pawl V, thereby lifting it out of gear with the
crown ratchet wheel R. at the same time the spur teeth 3 on the bar Z gearing with
the quadrant 4 operates the same, raising the arm 5. by which one of the detonator
arms Q. is raised clear of the rails to the position shown by dotted lines in Fig. 7.
When the signal is again put on, a weight 6. attached by a chain or the like 7. to
the underside of bar 21 pulls the said bar back to its original position, thereby
lowering the pawl V. into gear with the crown ratchet wheel K. and releasing an arm
with a detonator which falls upon the rail.
Attached to the frame M. and surrounding but not secured to the before mentioned
compound wheel, is an upper casement 9. in which is formed opposite to the mils of
the permanent way an opening, one side of which is vertical, and the other inclined
to a suitable angle. As the ring P. is rotated, and the arms Q. arrive at the vertical
side of the opening, they are respectively forced into the same by the extended
end Q of the lever coming into contact with the end of lever 11. in the manner as
hereinafter described, and as the pawl V. drives the wheels and attachments round,
the arms Q are raised by sliding up the inclined side of opening.
The arms Q. except when opposite the before mentioned opening through the
upper casement 9. are held somewhat in a vertical position, and as before mentioned
are provided with a rear extension Q. As the arms arrive opposite the said opening,
the rear extensions Q' come in contact with the inclined surface 10. of the lever 11.
provided at the opposite end with a suitable counterweight 12, the rear extensions on
sliding up the inclined surface of said lever displace the arms Q, causing them to
leave the vertical position and descend into the opening thereby ensuring the
detonator Qattached thereto being placed on the line.
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed, we declare that what we claim is :-
1. The combination of the rail B. with the bar L, lever S. and crown ratchet
wheel R, all armaged and operated substantially in the manner and for the purpose
as hereinbefore set forth.
2. The bar Z provided with a protuberance 2. combined with pawl V. and crown
ratchet wheel R. arranged substantially in the manner as shown and described and
for the purpose as herein before set forth.

page_text: 3. The bar Z combined with quadrant 4, arms 5 and Q: and detonators Q³,
substantially in the manner and for the purpose as hereinbefore set forth.
4. The rotating ring P. carrying detonator arms Q. combined with lever 11. and
opening through upper casing 9. having an inclined elevator for raising the
arms Q, all arranged and operated substantially in the manner and for the purpose
as herein before set forth.
5. The combination of the compound wheel and crown wheel with the arms or
levers W. Y. and W arranged substantially in the manner and for the purpose as
hereinbefore set forth.
6. The general combination of the parts forming the complete apparatus arranged 1
substantially in the manner and for the purpose as herein before set forth.
