IMPROVEMENTS IN OR APPLICABLE TO LAMPS
Year: 1888

page_text: I, FRANCIS JOSEPH BATEMAN ALLEN of 44 Upper East Smithfield in the City of
London, Merchant and Manufacturer, do hereby declare the nature of my said
for "IMPROVEMENTS IN OR APPLICABLE TO LAMPS" (a_communication to me from
abroad by Simon Biheller, Clerk, usually of 44 Upper East Smithfield aforesaid, but
at present travelling in the Kingdom of Belgium) and in what manner the same
is to be performed to be particularly described and ascertained in and by the following
statement:-
This invention has for its object so to construct a lamp that it may be readily used
either as a suspension lamp or as a table lamp, that is to say either be suspended (say
from the ceiling of a room) or be placed on any horizontal surface and be supported
from below.
In the accompanying drawings Fig. 1 shows in elevation a lamp embodying this
invention full lines indicating the parts in that postition which they assume when the
lamp is used as a table lamp dotted lines showing the position of the parts when the
lamp is to be suspended. Fig. 2 is a plan showing a lamp-vase embodying this inven-
tion with the lamp proper removed.
A is a vase of the usual construction into which fits a lamp of any suitable kind.
B B are arms which at bare so hinged to the vase that they may swing round in the
manner shown in the drawings. C is a boss on the vase tapped for the reception of a
screw D which forins an ornamental terminal or drop on the bottom of the vase and
has a flange d also of ornamental shape and acting as will presently be described.
B' are extensions on the arms B capable of entering between the flange d and the
bottom of the boss C. At projections or striking pieces are provided on the arms B
so as to limit their upward motion. L fig. 1 is the lamp.
Now when the lamp is to stand the screw D is screwed downwards the arms E are
Jowered until the extensions B' enter between the flange d and boss C, the screw D
is then tightened again and the arms B then form a stand or support for the lamp
their motion being prevented by the pressure of the screw D upon the extensions B.
If the lamp is to be suspended, the arms B are released from the screw D and brought
into the position shown by dotted lines in fig. 1 and in full lines in fig. 2.

page_text: The projections bearing against the vase limit the upward movement of the
arms B and these now serve for suspending the lamp. To this end chains or rods are
connected with the arms in the usual manner, the holes serving for receiving the
suspension hooks, or the parts 63 may be so shaped as to form hooks engaging with
the suspension rings or the like.
It will be readily understood that instead of providing a vase for the reception of
the lamp, the arms B boss C and the screw D may be provided on the body of the
lamp itself. In some cases it may be preferred to form a male screw on the end
of boss C and make D to serve as a nut running thereon. In the drawings three
arms B are shown but their number may be varied if desired.
Such and similar modifications will however readily suggest themselves and call
for no specific description.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed as communicated to me by
my correspondent I declare that I claim :-
A lamp having arms B attached to its vase or body by hinges 6 in such a manner
that the arms may move up and down as illustrated in the drawings so that, when the
arms B are turned down and the extensions B' secured as described the whole may
form a standing lamp, whilst when the arms are turned up a suspension lamp is
formed substantially as specified..
