WILLIAM HENRY ELLIOTT Railway Inspector Thurles County Tipperary Ireland do
hereby declare the nature of this invention to be as follows:-
;
I fit an Iron Chair to Each Running Rail, which forms the Gauge tie to the Railway
or Tramway on these Chairs I have two fixed Arms, which carry a shaft between these
Arms, and on the shaft I have un Arm, which actuates a plunger. Lengthways with
the Rails in a slot or Box on the Chair, on the other end of the shaft I have a carriage to
carry the shaft, and also on this shaft I fix two other arms, to one side of one arm Lattach
the Rod, or wire, connections from the lever actuating the signal, on the other side of
this arm I attach the Rod or wire to the signal. On the other Arm I fix a balance
weight if I do not use a return rod or wire to the lever actuating the signal.
On the end of the point or points I fix a piece of iron or steel in which there are
two slots, one slot vertical, the other slot horizontal; in the vertical slot; I have a bolt
which holds a plunger; one end of which is in the horizontal slot, when the
point or points are moved, this plunger moves crosswise with the Railway; or
Tramway and if the point; or points; go to their proper position, or positions,
this plunger is clear of the plunger worked by the shaft; and when the lever
actuating the proper signal is worked; the point, or points, will be locked; if the
point, or points, do not go to their proper position, or positions, the plunger worked
by the shaft will not pass the plunger on the point, or points, the error in working
is then detected; and the signal will not come off to allow a train, or fram to
pass.

page_text: Having now particulaily described and assertained the nature of my said Invention,
and in what manner the same is to be performed, I declare that what I claim is
1. A Combined Tic Chair, Point Detector and Lock.
2. The Method or system of detecting at the Extreme Point, or End, or Ends of
Tongues of the Switch or Switches, anything being amis or wrong which would prevent
them going close to the stock or running Rails. Such as anything foul being between
Switch and rail, or any of the rods, wires, or Connections being out of order or broken,
and when such is the case the detector preventing the Signal Arm or Arms from
being Lowered by the Signalman at the Lever frame to an allright Position.
3. The Mechanical means as shown on my Drawings for accomplishing the detection
and Interlocking of the Points and Signals.
