A Novel Device for Use in connexion with Lamp Chimneys.
I, FRIEDRICH FERDINAND WILHELM LUDWIG MÜLLER, of 64 Aterwall,.
Hamburg, Germany, Hardware Manufacturer 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 :-
As is well known the mantles and other incandescence-bodies employed in
incandescence gas-lighting, and in the Auer system in particular, are very fragile
in consequence of their delicate pseudo-textile structure, and cannot, therefore,
be too well protected from contact with other bodies and from shock and
vibration.
The removal of the lamp-chimney from the burner and the replacing of the same
upon the burner, for cleaning purposes, therefore requires a certain amount of care
and skill, in the absence of which the incandescence-body may very easily be
damaged or even entirely destroyed.
Now, the present invention has for object to provide means for safely guiding
the lamp-chimney both in removing and in replacing the same.
A simple and convenient device for this purpose is illustrated in the accompanying
drawings, in which Fig. 1 is a side elevation and Fig. 2 a plan thereof.
It comprises a ring or part a shaped or adapted to fit the outer contour of the
burner or chimney holder, and three, four, or more spring arms b which are attached
In the
to the ring a and the upper ends of which are bent slightly outwards.
ring a there are formed recesses or wider parts a¹ which serve to facilitate the
slipping of the ring over the burner-gallery or chimney holder c.
When it is desired to remove a lamp-chimney, the ring a is passed down over the
lamp-chimney d and the burner-gallery c, the spring-arms b bearing elastically
against the chimney. If now, the chimney be drawn upwards out of the burner-
gallery the chimney will be guided in a straight manner between the arms 6 until
after its lower edge has moved above the mantle or incandescence body f, so that
it will not come into contact with such incandescence-body. After the lamp-
chimney has been properly cleaned, it is put back into its original position, being
guided thereto by the spring-arms b and its insertion being facilitated by the upper
outwardly bent ends of the said arms.
When the chimney has been replaced in this manner and is again held by the
burner-gallery as before, the guide can be slipped off again in an upward direction
and be kept with the other cleaning-implements ready for subsequent use.
The guide a b is not intended to be left permanently upon the burner, but
is only to be used when required. It has been found to be of great practical
utility.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. A device for guiding a lamp-chimney in a straight manner whilst the same is
being put into position for use and whilst being removed, comprising a ring or part a
adapted to be readily attached to and removed from the chimney holder or part in
connection therewith and provided with spring-arms 6 substantially as herein
described.
