And of course some lamps had their own relighting facility:- for
example- forcefully driving a relighting 'key' (actually a toothed metal
strip) into the lamp rapidly turned a wheel against a flint to generate
sparks to relight the wick. These lamps were carried by officials and
people such as surveyors- but you had to be 'authorised' to guard
against relighting the lamp in an explosive atmosphere.

In some cases it was possible for these flame safety lamps to be relit.
There were lamp 'relighters' which were permitted to be used
underground. In my experience they were generally used in places such as
'bord & pillar districts' The relighter had to be located at a suitable
point such as a 'deputy's meeting station'. I have seen relighters that
could be used on lamps of Patterson manufacture and perhaps on lamps of
other makes as well. The relighter may have been made by Patterson or
possibly by Davis Derby. In use the safety lamp was placed in a locating
ring inside the unit and a flameproof cover was then closed so that a
key could be inserted in order to turn a hand operated generator which
produced a spark inside the lamp and relit it. The key was removed, the
flameproof cover opened, and the lamp removed.
If a lamp of a shaft bottom worker went out it was usually sent back to
the lamp room on the surface and relit before being sent back down
underground.
