1, WILHELM WEICKART, Reinitzer Strasse 15, Leipzig, Metal Lamp
Manufacturer, do hereby declare the nature of this invention to be as follows:-
The object of my invention is to produce a lamp which can be used either as a
table lamp or as a bracket or wall lamp, and in carrying out my invention 1 proceed
in or in about the following manner. To the base of the oil reservoir I attach a
semi-circular piece of metal plate of suitable thickness, the edge of the plate
being in a vertical plane. The periphery of this semi-circle is notched and in
practice I generally prefer to use three notches, one being at the lower part of the
semi-circle and the two upper ones opposite to each other and at right angles to
the first one. Through the centre of the semi-circular plate passes a pin, which
turns in a fork like piece of metal or other suitable material, the space between
the fork being equal to the thickness of the semi-circular plate. This fork-likė
piece of metal is attached to the top of a stand. This stand consists essentially
of two parts, a vertical tubular part or pillar and a lower extended foot or base.
Within the pillar is a tubular plunger closed at its upper end. A spiral spring
one end of which presses against the bottom of the tubular pillar, and the other
end against the closed top of the plunger keeps the latter at the upper part of the
pillar. Near the top of the pillar are two vertical slots opposite each other, and
surrounding the top is a band of metal whose inner diameter slides easily over the
outside of the pillar. Through each slot in the pillar passes a pin connecting the
external band with the internal plunger. At the closed end of the plunger is a
flat pin or the like passing up through the base of the fork. When the lamp is
employed for table use, the flat pin enters the lower notch in the semi-circular
metal plate. To convert the lamp for use as a bracket or wall lamp, all that is
required is to press down the band towards the base of the lamp, this forces down
the plunger inside the pillar and so draws the flat pin out of the notch. The base
of the lamp can then be turned through 90 degrees and on releasing hold of the
band the spiral spring will return the plunger to its normal position and push the
flat pin into one of the other notches. Provision is made for hanging up the lamp
on the wall or elsewhere when to be so used. Such provision may take the form
of holes made in a plate or the like covering the bottom of the base of the lamp.
The lamp may be made of any suitable material or combination of materials, but
I generally prefer to make it of brass. The above described arrangement of
stand, pillar, joint and provisions for retaining the lamp in its required position
and so converting it from a table to a bracket or wall lamp, is applicable to electric
and other lamps as well as for those consuming oil or the like.

Improvements in connection with Lamps for Domestic and
other Uses.
I, WILHELM WEICKART, Lamp Manufacturer of Reudnitzer Strasse 15,
Leipzig, Germany, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
The lamp, a sketch of which is given in the accompanying drawing, is intended
to be used as a stand- and wall-lamp, and is constructed as follows:-
Beneath the oil-font is fixed a regulating joint A, which has several slots, and
can be turned sideways, either to the right or to the left, on a pin fixing it to the
pillar. Inside the pillar is a plunger with a pin B, which, being attached to a
spring, catches the slot opposite to it, and by this means keeps the lamp firmly in
the position required. In order to convert the lamp, either into a stand- or into a
wall-lamp, one hins simply to bend sideways either the font or the pillar of the
lamp, by doing which the springy pin B yields and is released from its slot, and
ready to catch another slot, according to the desired position of the lamp.
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 :-
1. The regulating joint with its slots A.
