PROVISIONAL SPECIFICATION.
Improvements in Lanterns or the like for Use in Lighting by
Means of Gas or otherwise, and Means for Supporting same.
I THOMAS SYDNEY MARRIAGE of Bell Street, Reigate, in the County of
Surrey, Ironmonger do hereby declare the nature of this invention to be as
follows:-
This invention relates to the construction of lanterns and the like protective
appliances for use in lighting by means of gas or by other illuminating means and
the arrangements of the parts for supporting and retaining in position such lanterns
or their equivalents, the burners and other adjuncts.
These improvements will be found highly useful for employment when the
lanterns, or the like are used as protective covers for incandescent gas burners,
such as for street lighting, whilst they are also adaptable to other description of
lighting, as by electric energy, oil and other means.
One of the main objects sought to be attained by the present invention is to avoid
the inconveniences and evils arising from the present method of supporting street
and such like lamps and lanterns by means of rigid supports, whereby the effects
of vibration, such as that caused by the traffic in the street, or arising from similar
disturbing causes are severely felt, causing destruction of "mantles" and other
injuries.
In carrying out my invention I avoid the use of rigid supports or points of
contact between the lantern and its supports and retaining means and use instead
spring supports and retainers, and these are supplemented in some cases by
suspended weights and elastic buffers.
In applying my invention to a lantern for street lighting by means of gas ignited
and burned according to what is known as the incandescent system I support the
lantern parts on a suitable post bracket or other support by means of an
appropriately shaped rod or "iron" which over the lantern may take the form of a
scroll and from this depends a spring, or springs, and to this spring is attached the
lantern frame, cover and parts, including the shade which may be a clear cylinder
of glass. This glass may rest on an adjunct to, or continuation of the dependent
pipe which supplies the burner and supports the "mantle" and parts, or the other
equivalent lighting device. To this pipe, or its connections is also attached another
spring also attached to the vertical support or framing referred to to obtain lateral
control or retaining means, to prevent or control the swaying motions of the lamp
so as to avoid jars.
The gas supply tube may pass up the framing from the post and be carried to
and down within the lantern to the burner-the portion between the framing and
the lantern parts being made to take the form of an elegant scroll or other figure-
using flexible rubber or other connections between the supply and the dependent
pipe.
By these means the spring parts are made to absorb, or reduce the destructive
effects of shocks, or vibration, such as from street traffic, railway trains and the
like, which otherwise would have a destructive or injurious effect on the lighting
devices.

London and is indicated by Figs. 1 and 5 of the drawings.
The flexible inetallic tube / forms a connecting passage between the supply
pipe a and the dependent pipe d and also serves as a spring buffer to control the
swaying motions of the lamp. The said tube f is provided with connections f¹
and f
The pipe d extends downwards from the connection f to the lower part of the
lamp. In some cases I form the said connection f of a T shape in order to give
greater strength to the chimney 9, see broken lines f³ in Fig. 2.
The spring b is suspended from the scroll-like iron by means of suitable connec-
tions 6', its lower end being connected to an extension of the cover h. In some
cases I may prefer to employ more than one spring b, and if desired, a chain or the
like may be provided-fastened to the connection 6' at one end and to the cover h
at the other-in order to prevent the lamp falling in case the spring breaks; dis
a clamp to hold the dependent pipe d in place.
i is a
From the lower end of the pipe d a branch pipe d' leads to the burner e.
supporting arm for the bottom of the lantern which may be a disc of glass k,
removably connected thereto, and provided with holes through which the cords or
chains 1, 1, pass. The glass disc k is held to its supporting arm i by spring pressure,
a spring being connected to a part of the arm i, its lower end carrying a locking
piece. The cover k³ has a bottom piece k shown in Figs. 10 and 11 by plan
view and cross sectional view respectively.
In assembling the parts into position, the locking piece k passes through a
hole Fig. 10, when it is pulled downwards, against the tension of the spring,
until the reduced portion can be pushed into the slot k'. The shoulder then
supports the bottom piece and with it the cover k³, the upper edge k pressing
against the glass disc k, by reason of the spring k¹.
Figs. 6-9 show an alternative method of removably supporting the glass disc k.
The locking piece is herein shown provided with two latches or wings kok¹º,
centred at ", and capable of being folded into the slot 2 in order to allow the
locking piece k³ to pass through the hole k. The wings then fall outwards see
Fig. 8, in order to give the support. As are stop pieces.
By these means the spring parts are made to absorb, or reduce the destructive
effects of, shocks, or vibration, such as from street traffic, railway trains and the
like, which otherwise would have a destructive or injurious effect on the lighting
devices.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is:-
1. In a lantern or the like for use in lighting by means of gas or otherwise the
use of spring supports and elastic connections for retaining the same in proper
position, substantially as set forth.
2. In a lantern or equivalent protective appliance to an illuminant the arrange-
ment or combination and use of parts for effecting flexible metallic connection
between the same and the source of supply of illumination, as set forth.
3. The construction and use of parts of lanterns or equivalent protective appliance,
to an illuminant and means of access to the interior thereof as and for the purpose
set forth.
4. The construction and use of the means for removably closing the bottoms of
the lanterns or illuminant protective appliances as described and shown by the
drawings particularly with reference to Figs. 3 and 6-11.
