A Guard or Protector for use with Mantles for Incandescent Gas
Lighting Lamps.
I, ARTHUR TREWIN, Osbourne House Watford Draper do hereby declare the
nature of this invention to be as follows:-
This invention consists of a guard or protector for use with mantles for incandes-
cent gas lighting lamps, the object being to protect the mantle from injury.
The guard or protector may be formed of any suitable material or shape, being
carried in the lamp so as to enclose and protect the mantle.
In carrying out my invention I find it convenient to form the guard or pro-
tector of metal, or wire which may be bent or shaped to the desired form, or the
device may be constructed from separate pieces of wire or other material, &
which forms a cage or protector around the mantle.
Dated this 13th day of September 1897.

A Guard or Protector for use with Mantles for Incandescent Gas
Lighting Lamps.
I, ARTHUR TREWIN, Osbourne House, Watford, Draper, 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 consists of a guard or protector for use with mantles for incandes-
cent gas lighting lamps, the object being to protect the mantle from injury.
The guard or protector may be formed of any suitable material or shape, being
carried in the lamp so as to enclose and protect the mantle.
In carrying out my invention I find it convenient to form the guard or pro-
tector of metal, or wire which may be bent or shaped to the desired form, or the
device may be constructed from separate pieces of wire or other material, and
which forms a cage or protector around the mantle.
In order that my invention may be fully understood, I will now refer for
purposes of illustration to the annexed drawings, in which:-
Figure 1 is a perspective view shewing the guard or protector in position.
a is the guard or protector which may be formed of wire or other suitable
material, and which is placed as shewn around the mantle b, c being the ordinary
glass or chimney. In the event of a glass breaking, the guard or protector pre-
vents the pieces coming into contact with the mantle, and again, in moving the

page_text: lamp about the ordinary shake which takes place in a mantle is prevented and
owing to the very fragile nature of these mantles the use of this guard or pro-
tector will greatly increase the life or length of time in which the mantles will
wear.
The shape or construction of the guard or protector may be varied to suit the
circumstances under which it is used, as although I have shewn a guard formed
of separate pieces of wire the guard if desired may be formed of one continuous
piece of wire which can be bent or shaped as required.
Having now particularly described and ascertained 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 guard or protector formed of suitable material such as wire and which
is placed over the mantle of an incandescent gas lamp for the purpose of preventing
injury to same.
