Improvements in or relating to Retaining and Guiding Devices for
Lamp-chimneys.

1, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention to be as
follows:-
This invention consists of two rings preferably of metal held at a certain distance
one from the other by thin metal wires, so that they form a kind of protective
shell round such a chimney as is used for an incandescent burner, for example.
Its object is the following
:-
Mantles of the well-known "Aner" kind are always subject to the risk of being
spoiled by the chimney coming in contact with them when the same is being taken
off or put on again, so that nervous persons are afraid to take off the chimney for
the purpose of cleaning it..
The arrangement, consisting of a metallic ring at the top and metallic ring at
the bottom and the connecting rods or wires is placed on the chimney when the
latter has to be taken off, in such position that the lower ring comes on the
gallery.
In order that the lower ring should remain on the gallery of the burner, this
ring is made in two parts which are joined in front by a hinge and turn round the
hinge when the two 'lugs projecting from the ring halves and ordinarily kept apart
by a spring are pressed together by hand.
By thus opening the lower ring it can be placed on or removed from the gallery
in the simplest manner, with the rest of the safety arrangement.
The top ring is wider than the chimney so that the latter can be withdrawn
without any friction at the top.
The connecting or carrying rods are preferably placed in sockets so that they
are held securely even without soldering.
When this safety arrangement is so placed on the gallery of the burner, then the
chimney can be simply lifted out without any risk of knocking the side of the
chimney against the mantle or risk of a contact of the lower edge of the raised
chimney, as the chimney is guided all the time that it is within reach of the
mantle.
It is evident that for any number of incandescent gas-burners in any establish-
ment, public place or the like only one such arrangement is necessary, which can be
placed on one chimney after another, without loss of time when it is necessary to
clean the chimneys or to replace the broken ones.
Should this arrangement be left constantly on some one chimney, for instance
near the door or where it is exposed to draughts, then this arrangement in addition
to being used for the above mentioned object can be employed also for the purpose
of preventing the chimney from falling to pieces whenever it breaks.

I, ALFRED JULIUS BOULT of 111 Hatton Garden in the County of Middlesex,
Chartered Patent Agent, 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:-
Devices for the purpose of removing chimneys from incandescent and other lamps
in which there are fragile pieces, such as mantles without the danger of breaking
such pieces, have hitherto been made whereby, for instance, the chimneys could be
lowered, or two closed rings connected by rods have been employed. The object
of the present invention is similar to that of the devices just mentioned but offers
greater advantages than these. By connecting a closed ring with a hinged or
expansible ring, controlled by a spring, such for instance, as used to hold candles,
a device is obtained which is very easy to handle and to adapt to galleries of
different widths, and is very readily fixed in place. This device is shown in
elevation in Figure 1 and in plan in Figure 2 of the accompanying drawing. It
consists at its lower end of a metal ring A consisting of two halves hinged together
and which can be opened to a desired extent by pressing on two handles or lugs
normally kept apart by means of a spring E. The upper closed ring B which is
of a greater diameter than the glass chimney and which enables the latter to be
withdrawn without any friction is supported from the lower ring by means of thin
metallic rods C secured to both rings and yielding slightly when the lower ring is
opened. By opening or expanding the lower ring the protective device may be
conveniently placed on the gallery of the burner; this device is securely fixed
therein as soon as the pressure on the handles ceases whereby it becomes possible
to remove or replace the chimney in the usual manner without running the risk of
breaking the mantle by a lateral shock or by contact with the lower edge of the
chimney. By handling the device by means of the projecting handles the device
may be put in place or removed, even when the chinney is hot without burning
the fingers. The supporting metallic rods may be fixed to the rings either by
means of sockets, soldering or otherwise, and any desired number of these rods may
be provided.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is :-
A safety device for guiding glass chimneys during their application to or
removal from incandescent burners having a hinged or expansible ring at its lower
end which may be opened by pressing two handles whereby the device may be easily
passed over the chimneys and fitted on galleries of different sizes substantially as
and for the purpose described.
