COMPLETE SPECIFICATION.
Improvements in Police and other Lamps.
1, JOHN WELSH, of 16 North Tay Street Perth, in the County of Perth,
Superintendent of Police, 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 :-
I take a lamp in use by the police or is commonly used by them, of any kind or
make or other kind of lamp, and I attach to the bottom thereof by a hinge a frame
having a glass disc set therein, of red or other coloured glass or other coloured
transparent material, but I prefer red coloured glass, which frame with disc, when
not in use, 1 encase at the bottom of the lamp and fasten it there with a catch, and
have thus always at hand the means for prompt signalling purposes.
If fire breaks out or if an accident takes place or if there be real or apparent
danger to foot passengers, residents, carriages or persons on horseback, from
whatever cause, I quickly unfasten the catch holding the frame with disc at the
bottom of the lamp, and bring the frame with disc over the glass face of the already
lighted lamp and fasten it there with a latch and at once make a danger signal, and I
continue to shew a danger signal till no longer required. I then unfasten the frame
with disc which I again encase at the bottom of the lamp and fasten it there, to be
ready for use whenever required on occasions such as I have named, as also under
many different difficult circumstances to give warning of danger by signals or to call
for beln or both.

Having now particularly described and ascertained the nature of my said inven-

claim is
The attaching by a hinge at the bottom of a police lamp or other kind of lamp, a
frame having a coloured glass disc or other coloured transparent inmaterial set therein
for signalling purposes.
Dated this 24th day of June 1890.
