(Cl. 240-123)
The invention relates to an electric lamp, and
more especially to a combination switch and light
control for floor lamps.
The primary object of the invention is the
provision of a control of this character, wherein
it is only necessary to turn the shade of the lamp
of the electric lamp for turning on or off the
same, thereby eliminating the necessity of look
ing or feeling for the usual lamp switch, particu
larly when in the dark, the intensity of the light 10
being readily controlled simultaneously when
turning on the light.
Another object of the invention is the pro
vision of a control of this character, wherein the
same is unique and compact, and avoids the use
of a button or snap-lever switch for service in
turning on or off the light.
A further object of the invention is the pro
vision of a control of this character, which is
