PROVISIONAL SPECIFICATION.
Improvements in Spring Candle Lamps.
I JOHN CRAMPTON of Moat Farm, Wiston, near Steyning in the County of
Sussex, Farmer, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in spring candle lamps and has for its
objects to indicate the length of candle consumed without having to unscrew the
top of lamp and take out the candle and also to enable the spring to be held back
while the candle is being inserted.
According to this invention I have a vertical slot down the tube and to the
candle holder under which the spring is held I screw or otherwise connect
horizontally an arm so as to work in said slot the said arın may carry a disc
communicating with the lower end of said slot I make a short horizontal slot so as
to form a bayonet slot at this end in order to hold the spring compressed when
required by means of aforesaid arm.

COMPLETE SPECIFICATION.
Improvements in Spring Candle Lamps.
I JOHN CRAMPTON of Moat Farm, Wiston, near Steyning in the County of
Sussex, Farmer, 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 relates to improvements in spring candle lamps and has for its
objects to indicate the length of candle consumed without having to unscrew the
top of lamp and take out the candle and also to enable the spring to be held back
while the candle is being inserted.
According to this invention I have a vertical slot down the tube and to the
candle holder under which the spring is held I screw or otherwise connect
horizontally an arm so as to work in said slot the said arm may carry a disc
communicating with the lower end of said slot I make a short horizontal slot so as
to form a bayonet slot at this end in order to hold the spring compressed when
required by means of aforesaid arm.
And in order that my said invention may be better understood I will refer to
the drawing accompanying this Specification which shews my invention applied to
a carriage lamp.
Fig. 1 is a vertical section and Fig. 2 view of tube detached (in elevation).
a shews the tube of lamp to contain the candle and spring c iu the ordinary
way.
The tube a is provided with a bayonet slot d. e is a piece of tube closed at both
ends this tube comes between the spring c and candle b and has a pin f fixed thereto
at its lower end.
When it is desired to put a candle in the lamp the tube a is unscrewed from
lamp and the pin f (which protrudes through slot d) is drawn down to bottom of
said slot then pushed round so as to be locked therein as shewn at Fig. 2, the
pressure of the spring thus being taken off the piece e the candle can be dropped

page_text: in the tube a, and when this latter is again screwed into the lamp in the ordinary
way the pin is turned back so as to allow it to work freely up the slot d which
releases the spring c so that its pressure may be exerted against the piece e in order
to keep the candle b up in position.
By this means it will be far easier to screw the tube a on to the lamp than is now
the case the spring c being held down during this operation and further the amount
of candle consumed may be ascertained by looking at the height of the pin f in
the slot d.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In spring candle lamps the slot d and pin f substantially as and for the
purposes set forth.
2. Spring candle lamps constructed substantially as set forth.
