PROVISIONAL SPECIFICATION.
Improvements in Tubular Lanterns.
I, LEWIS THOMAS WILLIS of the firm of Everton & Willis, Lamp Manufacturers,
Communication Row, Bath Row, Birmingham in the County of Warwick, do hereby
declare the nature of my said invention to be as follows:-
My invention has for its object improvements in tubular lanterns which are also
known as "Hurricane Lanterns" as they are specially designed and adapted
to withstand very high winds for outdoor purposes. Lanterns of this class have
been before the public for a long time and various attempts have been made to
operate the shield glass so as to give easy access to the wick and burner for the
purpose of trimming the same and for the renewal of oil but such attempts have
been more or less complicated. Now my invention is for the purpose of allowing
easy access to the burner in a simple and effective manner and it is as follows:-
To the hot-air-tube or frame of the lantern I attach runners or guides which may
be either single or double and to the glass guard or other portion of the frame I
I then form the top of
attach staples or eyes or forks which embrace the runners.
the air tube over the glass sufficiently high to allow the glass to be lifted clear of
the burner in a vertical direction. In doing this the bonnet over the top of the
glass slides over the hot air tube. To lift the glass I may use an elbow pivotted
to the air tube and acting underneath the glass guard or other portion of the frame
or a double elbow or a single or double cam or I may recess or bend the runner of
runners with a notch or notches and so fix them that a natural spring will be
imparted thereto so that when the glass is lifted the eyes embracing the runners
will spring into the notches and secure the glass either in its elevated or depressed
position without the use of the elbow or cam devices before mentioned or in con-
junction with such as may be. desired. The natural spring given to the runners
also tends to steady the glass when down.

Improvements in Tubular Lanterns.
I LEWIS THOMAS WILLIS of the firm of Everton & Willis Lamp Manufacturers.
Communication Row Bath Row Birmingham in the County of Warwick do hereby
declare the nature of my said invention and in what manner the same is to
be performed to be particularly described and ascertained by the following
statement:-
My invention has for its object improvements in tubular lanterns which are also
known as Hurricane Lanterns as they are specially designed and adapted to withstand
very high wind for outdoor purposes. Lanterns of this class have been before the
public for a long time and various attempts have been made to operate the
shield glass so as to give easy access to the wick and burner for the purpose
of trimming the same and for the renewal of oil but such attempts have been more
or less complicated. Now my invention is for the purpose of allowing easy access
to the burner in a simple and effective manner and is as follows:-
To the hot air tube or frame of the lantern I attach runners or guides which may
be either single or double and to the glass guard or other portion of the frame
I attach staples or eyes or forks which embrace the runners 1 then form the top of

page_text: the air tube over the glass sufficiently high to allow the glass to be lifted clear of
the burner in a vertical direction. In doing this the bonnet over the top of the
glass slides over the hot air tube. To lift the glass I may use an elbow pivotted to
the air tube and acting underneath the glass guard or other portion of the frame or
a double elbow or a single or double cam or I may recess or bend the runner or
runners with a notch or notches and so fix them that a natural spring will
be imparted thereto so that when the glass is lifted the eyes embracing the runners
will spring into the notches and secure the glass either in its elevated or depressed
position without the use of the elbow or cam devices before mentioned or in con-
junction with such as may be desired. The natural spring given to the runners also
tends to steady the glass when down.
In order that my invention may be clearly understood and more easily carrried
into practice I have appended hereunto a double sized sheet of drawings upon which
I have fully illustrated the nature of my said improvements
Figure 1 is a front elevation of one of my lanterns when closed.
Figure 2. is a similar elevation to Figure 1 but shewing the lanterns open.
Figure 3. is a view shewing the lifting arrangement.
Figure 4. shews a modification in the guides.
In carrying my invention into effect I attach the guides a to the hot air tube A
through which the glass guards B run while the hot air chamber D is sufficiently
high to allow of the glass E and its support e¹ being raised into the position shewn
by Figure 2 in doing which the bonnet slides up the hot air tube F. For raising
the glass the elbow H is provided and is pivoted to the air tube A at a² the loop /¹
being formed to engage with the horizontal guard of the glass or other portion of
the frame. In place of the elbow H I may use a cam for lifting the glass or I may
provide runners on the air tube A Figure 4 which would be bent or recessed at Å¹
and so as to form a notch or notches and so fix them that a natural spring will
be imparted and thus retain the glass in its raised or lowered positions without the
use of the elbow H while the natural spring of the runners always tend to steady
the glass when down.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1st. The improvements in tubular lanterns substantially as and for the purpose
herein set forth and shown upon the accompanying drawings.
2nd. The improvements in tubular lanterns consisting of the runners and guides
in combination with sliding bonnet and with or without the lifting arrangement
substantially as and for the purpose herein set forth and shown upon the accom-
panying drawings.
3rd. In improvements in tubular lanterns the lifting arrangement substantially as
and for the purpose herein set forth and shown upon the accompanying drawing.
