We ALFRED HENRY GRIFFITHS Managing Director of Evered and Company of
Surrey Works Smethwick in the County of Stafford Manufacturers and ARTHUR
ROBBINS of No. 4 Cuthbert Road Birmingham in the County of Warwick Die Sinker
do hereby declare the nature of this Invention to be as follows:-
The said invention consists of the combination or arrangement of the parts herein
after described for connecting the burners of the said oil lamps to their oil reservoirs.
By this invention the connection and disconnection of the said two parts of the
lamp are effected in a simple manner the connection is very secure and the connecting
parts are not liable to get out of order.
We make at a short distance above a shoulder near the bottom of the burner two
projecting tongue pieces or catches which are situated at opposite sides of the burner.
They are flat excepting at their ends which are rounded or bevilled.
To the upper face of the metallic mount fixed on the top of the oil reservoir_two
inclined staples or angular loops are fixed that is to say the staples are not fixed
parallel to the face of the mount but are slightly inclined thereto so that the space
between the staple and the face of the mount diminishes from one end to the opposite
end. Under these inclined staples the tongue pieces or catches on the burner are
engaged as hereinafter described. The said inclined staples are situated at opposite
points on the mount the higher end of one inclined staple being presented to the lower
end of the other inclined staple. The higher end of each staple is cut away at its inner
side to permit of the flat tongue pieces or catches on the burner being introduced
under or removed from under the said staples.

page_text: In connecting the burner to the oil reservoir the said burner is depressed upon the
mount of the oil reservoir in such a position that its projecting tongue nieces or
catches take into the cut away parts at the higher ends of the inclined staples. By
now giving a twisting motion through a small angle to the burner its tongue pieces
or catches engage under the inclined staples and travel towards the lower ends of the
said inclined staples. The tongue pieces or catches are thereby fixed by a wedging or
binding action under the inclined staples and the burner is thus securely fixed to the
oil reservoir. By a movement of the burner in an opposite direction to that by
which it was fastened the tongue pieces or catches are moved to the higher and open
onds of the staples from which they can be withdrawn and the burner detached.

An Improvement or Improvements in Lamps for Burning Light or
Volatile Oils.
We ALFRED HENRY GRIFFITHS Managing Director of Evered and Company
Limited of Surrey Works Smethwick in the County of Stafford Manufacturers and
ARTHUR ROBBINS of No. 4 Cuthbert Road Birmingham in the County of Warwick
Die Sinker do hereby declare the nature of the said Invention, and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement:-
The said invention consists of the combination or arrangement of the parts herein
after described for connecting the burners of the said oil lamps to their oil reservoirs.
By this invention the connection and disconnection of the said two parts of the
lamp are effected in a simple manner, the connection is very secure and the connecting
parts are not liable to get out of order.
We make at a short distance above a shoulder near the bottom of the burner two
projecting tongue pieces or catches which are situated at opposite sides of the burner.
To the upper face of the metallic mount fixed on the top of the oil reservoir, two
inclined staples or angular loops are fixed, that is to say, the staples are not fixed
parallel to the face of the mount but are slightly inclined thereto so that the space
between the staple and the face of the mount diminishes from one end to the opposite
end. Under these inclined staples the tongue pieces or catches on the burner are
engaged as hereinafter described. The said inclined staples are situated at opposite
points on the mount the higher end of one inclined staple being presented to the
lower end of the other inclined staple. The higher end of each staple is open at its
inner side to permit of the flat tongue pieces or catches on the burner being
introduced under or removed from under the said staples.
In connecting the burner to the oil reservoir the said burner is depressed upon the
mount of the oil reservoir in such a position that its projecting tongue pieces or
catches take into the open parts at the higher ends of the inclined staples.
By now giving a twisting motion through a small angle to the burner, its tongue
pieces or catches engage under the inclined staples and travel towards the lower
ends of the said inclined staples. The tongue pieces or catches are thereby fixed by
a wedging or binding action under the inclined staples and the burner is thus securely
fixed to the oil reservoir. By a movement of the burner in an opposite direction to
that by which it was fastened the tongue pieces or catches are moved to the higher
and open ends of the staples from which they can be withdrawn and the burner
detached.
Figures 1 and 2 represent elevations taken at right angles to one another of a
burner connected to the oil reservoir according to this invention; Figure 3 represents
a plan of a portion of the same; Figure 4 represents a front elevation of the same with
one of the inclined staples in section and Figure 5 represents the two staples in

page_text: section and exhibits the manner in which the flat catches or tongue pieces engage
under the said staples the section of the parts in Figure 5 being taken in a plane at
right angles to that in which the section of the part of Figure 4 is taken; Figure 6
represents a plan of the burner unfastened from the mount on the oil reservoir.
The same letters of reference indicate the same parts in the several Figures of the
Drawing.
a is the burner and b the metallic mount fixed on the oil reservoir c; d, d are the
two flat projecting tongue pieces or catches situated on opposite sides of the burner;
e, e are the two inclined staples or angular loops fixed on the upper side of the
mount of the oil reservoir c. The said inclined staples e, e are arranged at opposite
points on the mount & the higher end of one inclined staple being opposite the lower
end of the other inclined staple. The higher end of each staple is open at its inner
side, the open part being marked as best seen in the separate view of Figure 4
to permit of the flat tongue pieces or catches d, d on the burner being introduced
under or removed from under the said staples.
When the burner is to be fastened to the oil reservoir the connecting parts on the
burner and mount of the reservoir have the respective positions represented in Figure 6,
that is, the burner a is lowered onto the mount b so that the two flat tongue pieces d, d
are situated in front of the higher open ends ff of the inclined staples e, e. By now
giving a twisting motion to the burner in the direction indicated by the arrows in
Figure 6 the tongue pieces or catches d, d pass through the open ends, of the
inclined staples e, e and engage under them and travel towards the lower ends of the
said staples as represented in Figures 3. 4 and 5. As the tongue pieces d, d on the
burner a travel under the inclined staples e, e on the mount of the oil reservoir they
are fixed to the said staples by a wedging or binding action and the burner is thereby
securely connected to the oil reservoir.
In order to disconnect the burner from the oil reservoir, the burner is turned in a
direction contrary to that indicated by the arrows in Figure 6, when the tongue
pieces or catches d d are moved to the higher and open ends of the staples e e
from which they can be withdrawn as represented in the said Figure 6, and the
burner can then be lifted from the oil reservoir.
Having now particularly described the nature of this invention and the manner in
which the same is to be performed we declare that we claim as the said invention of
"An improvement or iniprovements in lamps burning light or volatile oils."
Connecting the burner of the lamp to and disconnecting it from the oil reservoir of
the said lamp by means of the flat tongue pieces or catches d d on the burner engaging
under or being removed from under the inclined staples or angular loops e, e, open at
one end, fixed to the mount of the oil reservoir the said parts d d and e, e being
arranged and acting substantially as herein before described and illustrated in the
accompanying Drawing.
