PROVISIONAL SPECIFICATION.
Improved Means for Opening and Closing Acetylene and other
Lanterns.
I, HERBERT JOHN HADDAN, of the Firm of Herbert Haddan & Co., of
18, Buckingham Street, Strand, W.C., Civil Engineer, do hereby declare the
nature of this invention a communication to me from abroad by Albert Frank,
of Sendlinger Oberfeld 39, München-Sendling, in the Empire of Germany, to
be as follows:-
This invention relates to improved means for opening or closing acetylene or
other lanterns or lamps such as are used on cycles or the like.
A wire bow is suitably pivoted at its two ends to the reservoir at the base of the
antern and is shaped or bent so that its form corresponds to the outline of the
lantern. On its upper part which in the closed position comes upon the top
of the lantern there is arranged in a folding manner a wire or the like lever which
8 so formed that when folded down upon the cap of the lantern it presses firmly
upon the same.
The lower border of the lantern body is seated in a groove provided in the
upper rim of the reservoir which groove is provided with an elastic or suitable
backing so as to form a tight joint. If the reservoir is to be separated from the
antern body then the lever has only to be lifted and the bow together with the
ever turned forwards whereupon the lantern body can easily be taken away from
he reservoir.

Lanterns.
I, HERBERT JOHN HADDAN, of the Firm of Herbert Haddan & Co, of
18, Buckingham Street, Strand, in the County of London, Civil Engineer, do
hereby declare the nature of this invention (a communication to me from abroad by
Albert Frank, of 39, Sendlinger Oberfeld, München-Sendling, in the Empire
of Germany), and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
The method employed up to the present time for connecting to the lantern itself
the holder or container full of the combustible, which has been usually effected by
screwing, offers the inconvenience that this method of closing, even when well
adapted, soon ceased to form a tight joint, and admitted of escapes of the com-

case of acetylene lamps or lanterns for under these conditions without mentioning
of the useless loss of gas, these lamps or lanterns are easily exploded. The
closing device forming the subject of the present invention has obviated or done
away with this inconvenience.
And in order that my invention may be thoroughly understood I now proceed
to describe the accompanying drawing thereof, reference being had to letters and
figures marked thereon.
Fig. 1, shows a side view of a lantern or lamp fitted with my closing device;
the stirrup of metallic wire a is represented therein with its eccentric b in two
positions closed and open (this latter in dotted lines):
Fig. 2, the lantern or lamp is shown in front view, partially in section through
the portion containing the tight joint.
The metallic wire stirrup a is supported at its two ends in the receiver or
container in which it turns and it is bent in order to adapt it to the shape of
the lamp or lantern.
Upon its upper transverse superior part a¹ which passes above the top of the
lamp or lantern, is situated the eccentric b. When it is lowered the eccentric
rests (see Fig. 1) upon the cap of the lantern or lamp, the arm of the lever of
the eccentric 6 resting itself upon the cap in a state of rest.
The lower edge of the body d of the lamp or lantern is here fitted into a
groove in the receiver or container c provided with a jointing ring or washer I and
thus forming a tight joint.
If the receiver or reservoir c has to be removed from the body of the lantern, all
that is required is to raise the eccentric 6 in the direction indicated by the arrow,
and move forward the stirrup a and with it the eccentric. b (see the arrow in Fig. 1)
after which the body d of the lamp or lantern can be easily removed from the
container or reservoir c.
In as much as the arrangement of the eccentric always admits of effecting a
powerful compression between the two parts to be connected together, it is
beyond a doubt that a lamp or lantern constructed in this manner will fulfill all
the necessary requirements so far as absolute tightness of the connection is
concerned.
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 closing device for acetylene or other lamps or lanterns, characterized by
the arrangement of a stirrup of metallic wire a surrounding the body of the lamp
or lantern and rotatably supported in the receiver or container for the com-
bustible c which carries at its upper transverse part a' an eccentric b which admits
of a powerful compression of the two parts of the lamp or lantern which are
rendered gas tight by a jointing ring or washer g substantially as hereinabove
described.
2. A closing device for acetylene or other lamps or lanterns constructed and
arranged substantially as hereinbefore described and illustrated in the accom-
panying drawing.
