page_text: We JOHN WILLIAM BERNARD WRIGHT of the firm of Wright and Butler Limited
Lamp Manufacturers New John Street West, Managing Director and HENRY JAMES
BURT of 78 Gower Street Lozells, Traveller both of Birmingham in the County of
Warwick, do hereby declare the nature of our said invention and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement :-
Our invention has for its object improvements in lamps and has special reference to
the lamps known as Hall Lamps by which increased facility is obtained for placing
the oil or other fount in position therein and for its ready removal therefrom which
we do very simply and also very quickly.
In order that the invention may be clearly understood and more easily carried into
practical effect we have appended hereunto a double sized sheet of drawings upon
which we have shown six figures illustrating its application to an ordinary Hall lamp
and from which the principle may be applied to other similar conditions in other
lamps.
Figure 1 is a broken off sectional elevation of a lamp showing the fount E held by
the hand H illustrating the operation of placing the fount in its position after being
refilled with oil or other light producing medium.
Figure 2 is a broken off sectional elevation of the same lamp showing the fount E
fixed and settled in its normal position as when burning.
Figure 3 is a plan of the same lamp but with the fount E removed so as to show
the rests Band B₁ quite clearly and in the position as indicated by Figure 2. The
outline of the fount E is however indicated by the dotted lines e¹.
Figure 4 illustrates a modification in which the rests K and M are operated some-
what differently as will be hereafter explained but the action shown is that of placing
the fount E in position.
Figure 5 shows the same lamp as Figure 4 but with the fount settled in its normal
position for burning.
Figure 6 is a plan showing the rests K and M in their normal position as indicated
by Figure 5 but with the fount E removed, its position being indicated by the dotted
lines

In the frame of any hall or other hanging or other similar lamp we hinge the
arms or rests B B' by the hinges 62 63 and the outline of the rests is indicated in
the plan Figure 3 the wire or other frame composing the rests being bent or
worked round at 6 to form a ring or two semi-rings to receive the fount E. In
their normal position the arms or rests are supported by two ears or other pro-
jections a a'. The action is as follows:-
The fount E is lifted against the hinged wire, or other rests B. B' as illustrated
at Figure 1 until they drop under the projection or enlargement e¹ when the fount is
lowered upon them and the hand is then removed. In the modification shown by
Figures 4, 5 and 6 the rest K will fall outwards as indicated by the dotted lines
Figure 4 when the fount may be placed sideways in the slot or jaw formed
by kk when it is lifted taking with it the supplemental flap M which is so con-
structed with a heel piece m² that when it has fallen back into its normal position this
heel rests against the side frame and the ends of K viz. k and k rests upon it as shown
at Figure 5. It will be obvious that these flaps may be operated by a suitable cord s¹
and tassel S by which one or both flaps may be lifted or lowered as will be readily
understood.
We may make these flaps from any material and in any design but we have found
a wire frame to answer very well and it is both simple and strong. It will be obvious
that four flaps may be used in square lamps or six in hexagon or three or even one
flap with a fixed rest and slot to open inwardly would answer the purpose but our
illustrations shew simple and effective modes.
Having now particularly. described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
The improvements in lamps having hinged flaps which may be operated so as to
lift or fall to easily admit the fount substantially as berein set forth and shown upon
the drawings.
