PROVISIONAL SPECIFICATION.
Electric-lamp Adjuster.
GEORGE HENRY SAYER of 52 Upper Leeson Street Dublin, Mechanical &
Electrical Engineer, do hereby declare the nature of this invention to be as
follows:
My invention consists of an attachment applicable to all electric lamps which are
suspended by flexible cords. It consists of a spring lever clip of a suitable shape
attached by suitable means to the lamp holder.
This clip may have attached to it an arm bent to a suitable angle for greater
convenience. I may also use a small clip with spring attachment to be applied
direct to the lamp shade or reflector. Combined with these clips or arms I use
one or more grips of special form which can be easily moved up or down the
flexible cords forming the leads to the lamps, and which grip it firmly so as not in
any way to injure it.
By a suitable combination of the above any suspended lamp can be raised or
lowered or its position altered or adjusted to any angle or any height.

COMPLETE SPECIFICATION.
Electric-lamp Adjuster.
I GEORGE HENRY SAYER of 52 Upper Leeson Street Dublin Mechanical
Engineer 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:-
My invention consists of an attachment applicable to all electric lamps which are
suspended by flexible cords. It consists of a spring lever clip of a suitable shape
as shown in Fig. 1 in the accompanying drawings, and this is attached by suitable
means as for instance a cross bar and screw as shown to the lamp holder.
It will be seen that to meet variations in size in the holder the cross bar can be
changed to drop into suitable slots in the spring clip and thus approximately grip
the holder but be finally held by the screw marked A, a chain joins the two parts
to prevent the loss of the bar rendering the clip useless.
The clip may have an arm bent to a suitable angle as shown rivetted on or
otherwise attached to it, however this may (as an alternative arrangement) be
replaced by a clip (marked B in Fig. 2) applied direct to the lamp shade or
reflector.
Combined with these clips or ans, I use one or more grips of special form, (see
Fig. 3) which can be easily moved up or down the flexible cords forming the leads
to the lamp, and which grip it firmly but so as not in any way to injure it.
By a suitable combination of the above as shown in Figures 5. 6. 7. any sus-
pended lamp may be raised or lowered or its position altered or adjusted to any
angle or height.
It is clear that the alterations in position as shown in Figures 5, 6 & 7 apply
equally to form of attachment shown in Fig. 1.
A. double gripping device for better security may be formed if desired as shown
in Fig. 4.

page_text: 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
1st. The combination or arrangement of parts forming the lamp adjuster sub-
stantially as and for the purposes herein described in reference to and shown in the
accompanying drawings."
