PROVISIONAL SPECIFICATION.
An Improved Electric Light Standard for Workshops and
the like.
I, GEORGE STEGMANN of 69 St. John's Hill Clapham Junction in the County
of Surrey Electrical Engineer, do hereby declare the nature of the said invention
to be as follows:-
This invention has for its object an improved electric light standard for work-
shops and the like whereby great facilities are presented so as to bring the light
into close proximity to the work being done or in any other desired position or the
light itself can be readily unshipped and used independently of the standard itself
thus doing away with the dangerous practice of using matches and other exposed
lights when it is desired to see under the work bench and in various other places
where it is desirous to have a light.
According to this invention I construct an upright standard of any desired metal
the base of which is weighted or it may be provided with means for securing the
same to the bench by screws.
This upright standard is formed hollow to easily receive a spindle attached to
spring jaws or bearings in which the trunnions of a socket work, such spring jaws
or bearings are capable of being tightened up on to the ends of the socket by set
pins or fly nuts on the ends of the trunnions.
The spindle carrying the socket may be raised or lowered in the vertical standard
and held in position by a set pin in such standard.
The socket before referred to is arranged to receive a hollow rod or tube which
may be drawn in or out to any desired length in such socket and can be there
secured by a set pin. This hollow rod or tube is bent at one end and is provided
with the usual electric lamp holder.or socket. The wires of which pass through
such hollow rod.
It will thus be seen that a useful electric light standard may be constructed so
that the light can be raised in any direction and also to any height, or it can be
brought down on to the bench near the work being done, or if desired the spindle
carrying the socket may be lifted out of the upright standard and the light carried
to any desired spot.

An Improved Electric Light Standard for Workshops and
the like.
I, GEORGE STEGMANN of No. 69 St. John's Hill, Clapham Junction in the
County of Surrey Electrician do hereby declare the nature of the said invention
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 an improved adjustable electric light standard for.
workshops laboratories and the like whereby great facilities are presented so as to

page_text: bring the light into close proximity to the work being done or in any other desired
position, or the light itself can be readily unshipped and used independently of
the standard itself thus doing away with the dangerous practice of using matches
and other naked lights when it is desired to see under the work bench and other
places where it is desirous to have a light, it thus not only does away with the use
of naked lights but lessens the chance of fire.
In order that my invention may be properly understood and readily carried into
effect I will proceed aided by the accompanying drawings fully to describe the
same.
Figure 1. is a front view of one form of electric light standard constructed
according to my invention, with the lamp carrier tube in section.
Figure 2. is a side view shewing the lamp in one of its positions and
Figure 3. is a modification of the socket for holding the lamp carrier tube.
In all the figures like parts are indicated by similar letters of reference.
According to this invention I construct an upright standard or column a of any
suitable metal, the base a² of which is weighted, or it is provided with means for
screwing the same to the bench a* as shewn in the accompanying drawings.
This upright standard or column a is hollow and receives easily a spindle b
attached to the spring jaws or bearings c (or the standard if desired may be solid
and the rod carrying the socket hollow and made to slide over such standard) in
which the trunnions d, d', of the adjustable socket e work, the spring jaws or
bearings c are tightened up on the ends of the socket by a set pin on the end of
the trunnion d¹.
b
The spindle 6 carrying the socket e can be raised or lowered in the vertical.
standard or columu a and held in any desired position by the set pin a¹ in such
standard.
The socket e is arranged to receive a hollow rod or tube g which can be drawn
in or out to any desired position in the socket and there secured by the set pin f
binding on the jaws c. The hollow rod or tube g is provided at one end with the
usual electric lamp socket h reflector or shade k and lamp m.
The wires of
which pass through such hollow rod g.
In the modification shown at Figure 3 the socket e is shewn cut away sufficiently
at its upper part el to allow the tube g to drop therein, and it is provided with a
loose piece e capable of being forced against the tube g by means of the thumb
screw and thereby fixing the same.
It will thus he seen that a convenient and useful electric light standard may be
constructed so that the light can be raised in any direction and to any height, or it
can be brought down on to the bench near the work being done, or if desired the
spindle carrying the socket may be lifted out of the upright standard and the light
carried to any desired part.
With a slight modification of the light carrier my invention may be used for gas
by using flexible tubing.
'
Having now particularly described and ascertained the nature and construction
of my said invention and in what manner the same is to be performed I declare
that what I claim is-
1. An electric light standard for workshop laboratory and like purposes consisting
of a vertical hollow column having a rod fitting loosely therein, and capable of
being raised and lowered and fixed in any vertical position such rod carrying a
socket for the reception of a tube capable of being adjusted and fixed at any
desired angle, through such tube electric wires pass to an electric lamp fixed at
one end thereof substantially as herein described and shewn in the accompanying
drawings.
2. An electric lamp standard consisting of a vertical hollow standard or column,
an adjustable rod carrying a socket, or jaw or jaws for the reception of a tube
carrying the electric lamp such socket is capable of being turned about and fixed
at any angle and is provided with means for easily lifting the tube therefrom and

page_text: replacing and fixing same substantially as herein described and shown in the
accompanying drawings.
3. An adjustable standard for electric lamps suitable for workshop, laboratory
and purposes substantially as described and shown.
