We PERCY PALMER BURT and SAMUEL BRUCE EDMONDS both of 10 Great
Charles Street Birmingham in the County of Warwick, Manufacturers, do hereby
declare the nature of this invention to be as follows:-
-
This Invention is especially applicable to the standards of Lamps known as floor
lamps and is also applicable to the standards of lecterns reading desks, music stands
and other articles having stems or standards and requiring to be adjusted at varying
heights.
It consists in forming a rod or tube to carry the lamp or other article of metal or
other suitable material along the face of which a groove is formed within this groove
holes are pierced at any required intervals.
This rod fits into a hollow standard carrying upon it a lever one end of which has
upon it a peg passing through the standard and capable of taking into the holes in
the groove in the rod or tube the other end of the lever being formed as a thumb
piece. A spring on the underside of the lever throws it forward and causes the
peg to fall into any one of the holes in the groove in the rod or tube that may be
brought opposite to it by raising or lowering the rod or tube.
The holes in the rod or tube are slightly bevelled and the face of the peg cor-
respondingly formed to enable the rod or bar carrying the lamp or other article to
be raised without the necessity of raising the lever to release the catch.
To release the peg when lowering the rod or tube the thumb piece of the lever
s simply pressed down and the rod or tube carrying the lamp or other article
owered as desired.

page_text: We PERCY PALMER BURT and SAMUEL BRUCE EDMONDS both of 10 Great Charles
Street Birmingham in the County of Warwick Lamp Manufacturers 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, reference
being had to the accompanying drawings and to the letters and figures marked
thereon:-
This invention is especially applicable to the standards of lamps known as floor
lamps and is also applicable to the standards of lecterns, reading desks, music
stands, and other articles having stems or standards requiring to be adjusted at
varying heights.
It consists in forming a rod or tube to carry the lamp or other article of metal
or other suitable material along the face of which a groove is formed within this
groove holes are pierced at any required intervals.
'
This rod fits into a hollow standard carrying upon it a lever one end of which
has upon it a peg passing through the standard and capable of taking into the holes
in the groove in the rod or tube the other end of the lever being formed as a thumb
piece.
A spring on the underside of the lever throws it forward and causes the peg to fall
into any one of the holes in the groove in the rod or tube that may be brought opposite
to it by raising or lowering the rod or tube. The holes in the rod or tube are
slightly bevelled and the face of the peg correspondingly formed to enable the rod or
bar carrying the lamp or other article to be raised without the necessity of raising the
lever to release the catch.
To release the peg when lowering the rod or tube the thumb piece of the lever is
simply pressed down and the rod or tube carrying the lamp or other article lowered
as desired.
Referring to the Drawings in which similar letters of reference relate to similar
parts.
Fig. 1 is a front view and Fig. 2 a side view of a portion of the standard shewing
the parts to which our invention relates and Fig. 3 is a view of a complete standard.
(a) is the tube or rod for carrying the lamp or.other article working within the outer
casing () and having the groove (b) on it pierced with the holes (c). (d) is the
lever pivotted onto the carriage (e) and having the spring (s) underneath the thumb
piece (t) so as to throw up that end of the lever and cause the peg (p) at the other
end of the lever to fall into the holes (c) when brought opposite to them by raising or
lowering the rod (a).

page_text: The lower edge of the holes (c) being slightly bevelled and the end of the
peg being correspondingly sloped it will be possible to raise the rod (a) without
pressure upon the thumb piece (t).
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
A spring adjustment constructed substantially as herein set forth and specified to
be applied for varying the position of lamps lectern desks music stands and such
like articles upon their standards or supports.
