TITLE : "AN APPARATUS FOR SAFETY AND
SECURITY OF RAILWAY TRACK."
FIELD OF INVENTION :
The proposed invention offered for patenting relates to conventional safety
and security system of the railway organisation.
BACKGROUND/PRIOR ART :
In the prior art the conventional system for overall safety and security of
railway is not able to fulfil our demand, but often it is reflected in daily
newspapers.
DRAW BACK :
These conventional safety and security system are neither able to prevent
railway accidents nor save precious lives. But at the same time a huge amount
(Crores of rupees) is kept in the budget for the security every year. Rather our
Government has to face a lot of hazards.
OBJECT OF INVENTION :
Our object is to fulfil our aim and purpose as it will be able to prevent acci-
dents, to save precious lives, to cost a smaller budget, to avoid any loss or
damage
A SUMMARY OF THE INVENTION :
Here we propose a new method, a new direction, a new device to make,it
simple with less expenditure but high acceptability and reliability. It is a device
to prevent the accidents. A specially designed unit consisting of one green
indicator, one red indicator and a buzzer and also a special type of wiring over
the tracks. The glowing of green light indicates that the railway tracks are safe
but alarming buzzer and blinking of red indicator warns that the track is open
and an accident will take place very soon.

DETAILED DESCRIPTION OF THE INVENTION WITH REFERENCE TO
DRAWING :
The system is divided into several units. Each unit remains in each railway station
or between some stations in the room of station Master or in the room of signal
control or in any convenient place. In fig. 1 on sheet no. I it has been drawn a
sketch diagram of th ? out line and outlook of the unit. Dimension of each unit is
approximately 10" x S3" x 6". It can be changed according to the requisition and
the unit is electrically controlled. A single core enamel coated copper wire
comming out of an unit, travels along the middle position of the railway track upto
the point it is meant to cover and then returns back to the unit along other railway
line. The gauge of the wire will depend upon the distance it extends to. With this
arrangement a special protection must be taken for non-removal of fish plates.
This also will be a very simple device (Vide diagram no. fig. 2A, 2B and 2C on
sheet 2). On fig. 2A & 2B are the covers of fishplates on both sides. The size of the
cover is slightly larger than the fish plates, thereby enabling the fish plate to be
readily covered including all the nut bolts installed there. The cover will be made by
a strong rust proof materials, placing on both sides of fish plate, it will be fixed
together with two nut bolts (if possible) or can be joined together by spot welding
on both ends of the cover with the railway line. In fig. 2C it is specially designed
strong and rust-proof matalic cover of wiring over the fish plate's cover'; both
ends of this cover are partly bended, it will be installed over the covers of fish plate;
including the wire and must be fixed by spot welding with cover and railway line
As a result, no one can touch to remove the fish plates without tampering or
cutting the wire on the cover. So it will not be possible to do any sabotage activity
without notice of the railway personnel. In fig. 3 (a, b, c & d) on sheet no. 3 we have
shown the assembly of wiring, cover (d), fish plates' cover (c), and fish plate (b) on
railway track in the joint (a) between two ends of the tracks serially one after
another.
The unit will give signal wherever rail way track between any two units at any
point of separation of track or loosening of fish plates by any means or has been
destroyed or damaged or fish plates are removed by any militant activities. A green
light will always glow indicating that the track is safe and sound, on the other hand
if there is any damage or separation in the track, at once a red light will begin to
blink with consequent intense alarm bell in lieu of the green light. At that moment
the person (any railway man on duty) in that room will then instant. , communicate
to the next stations and the trains have to be stopped forthwith. Thus, accidents
can be averted. Besides, if tracks are damaged due to natural calamities or train
accident already occurred in secluded hilly or dense forest areas, in winter or rainy
seasons or at the dead of night, the authorities instantly will know about the
catastrophy and arrange for speedy relief measures. In effect, the device can save a
large number of lives.
Another point should be mentioned here, that we have to apply a special method
to address the issue of (a) expansion and contraction of track during summer and
winter respectively and (b) maintenance and repair of tracks. In any convenient
place of platform area, where the conducted wire has been installed, in fig 4 on
sheet no 4 a mainteinance box (4F) which is a season proof electrically non con-
ducting box made of any fibre, fibre glass, precast asbestos, ebonite, perpex sheet
or bakelite etc but fibre glass is preferable as it seves the purpose, and the size of
the box approx. (20"x2"x2") will be placed through which the wire will go.
Within the box there will be a strong metallic spring (4G). In fig. 4 on sheet no. 4,
the design of maintenance box (4F) with its lid for top cover (in fig. 4C) has been
shown. The box is to be made of non-metalic materials. The conducting copper
wire (4A) will go throught the box. After cutting the wire (2 :5 position) into the
box, the two ends of the wire will be connected with both ends of that selected
spring with two nut bolts and also a flexible insulated copper wire (4H) will be
connected on both joints as a shunt to make the contact rigid. The lid of the box (in
fig. 4C) will be fixed by screws with the maintenance box. The spring (4G) in the
box will counteract expansion and contraction. By unscrewing the nut & bolts and
the joints in the box, the mainteinance work will be facilitated.
In fig. 4E the design of the channel-type cover for the wiring has been shown.
The covers will be fixed on the body of one side of the track by spot-welding. The
size of the channel cover will be of a certain length.
The. sectional view of the track with channel cover has been drawn in fig. 4B on
sheet no. 4.
Lastly, the circuit diagram has been drawn in fig. 5A on sheet no. 5. The descrip-
tion is as follows :
