PROVISIONAL SPECIFICATION.
Improvements in Incandescent Lamps or Burners.
We, GEORGE BIRCH, of Rochdale Road, Manchester, in the County of Lancaster,
Engineer, WILLIAM REILLY, of Hyde Grove, Chorlton-on-Medlock, Manchester,
aforesaid, Engineer, and JOHN THOMAS COWMAN, of Conran Street, Harpurhey,
Manchester, aforesaid, Auditor and Accountant, do hereby declare the nature of
this invention to be as follows:-
This invention relates to incandescent burners for gas or oil lamps and is
designed to provide a support for the mantle or hood capable of being readily
removed and replaced without displacing the mantle therefrom whereby the
mantle may be removed and replaced for the purpose of cleaning the burner or
the like.
We provide a ring or washer forming an annular base to fit over or upon the
body of the burner and to this base we attach a supporting arm from which the
mantle is suspended.
The supporting arm or rod is shaped to extend over the centre of the burner
and is forked at the upper end to support the mantle. It may be made of any
suitable material. The annular base may be provided with a flange or collar and
fit loosely over or upon the burner so as to be readily removed or replaced and in
moving it the mantle is lifted and carried with it without fear of injury.

Improvements in Incandescent Lamps or Burners.
We, GEORGE BIRCI, of Rochdale Road, Manchester, in the County of Lancaster,
Engineer, WILLIAM REILLY, of Hyde Grove, Chorlton-on-Medlock, Manchester,
aforesaid, Engineer, and JOHN THOMAS COWMAN, of Conran Street, Harpurhey,
Manchester, aforesaid, Auditor and Accountant, 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 incandescent burners for gas or oil lamps and is

page_text: The burner A may be of any ordinary form for incandescent lighting by means
of a hood or mantle which is also of suitable construction and these form no part
of the invention.
We construct a ring or washer B forming an annular base to fit over or upon
the body a of the burner A with an arm or bracket 6 carrying at its extremity a
socket C to receive and support the crutch or forked rod D upon which the
mantle E is hung.
The annular base B and the arm b and socket C may be made of any suitable
material preferably sheet metal stamped, drawn, spun or otherwise formed out of
one piece. If made of a refractory material the crutch D and arm b may also be
in one piece but if made of metal the crutch D will be supported in the socket C.
In making the appliance it is formed with a second or outer flange F to protect
the base of the mantle and to provide a means to grip or hold it either solid as
in Figs. 1 and 2 or with perforations or air holes f as in Figs. 3 and 4. The
flange F is not essential and may be dispensed with, two lugs or finger pieces G
being provided one at either side by which to take hold of and lift the appliance
as in Figs. 5 and 6.
In the modification shown in Figs. 7 and 8 the base B is made separate from
the socket C which is supported above as shown. The upper part carrying, the
socket may be made either of refractory material or metal as desired.
The arm or bracket b is shaped so that the socket C. is in the centre of the burner
and two arms or more such as b may be provided instead of one to support the
socket.
The mantle or hood E is supported from the base B upon the crutch D inde-
pendent of the burner and can be removed therefrom as shown in Fig. 2 without
fear of injury and be again replaced.
It is to be understood that no claim is herein made for a protector for the
bottom edge of the mantle.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is:-
-
1. An appliance for incandescent lamps or burners comprising an annular base
to fit onto the burner and a socket or crutch to support the mantle whereby the
latter can be lifted and removed or replaced without fear of injury substantially
as described.
2. In an incandescent lamp the combination with an annular base to fit the
burner of an arm and socket to receive the crutch and support the mantle whereby
the mantle may be removed from or replaced upon the burner without handling or
fear of injury substantially as described.

page_text: 3. An appliance for incandescent lamps or burners having the parts constructed
and arranged in combination substantially as described and shown with reference
to either of the figs. of the drawings.
