Improved Holder Fastenings to Secure Globes or Shades for
Lighting Purposes.
JOHN HOWARD Ross 171 Hockley Lighting Engineer & EDWARD ELIJAH ATKINS
171 Hockley Chandelier Manufacturer both in the City of Birmingham do hereby
declare the nature of this invention to be as follows:-
The object of our invention is to provide a simple method of securing either gas or
electric globes or shades to their own fittings or holders, and may be used to secure a
globe or shade either resting on or suspending from said holders or fittings either one
or more arms are jointed to said holders or fittings, the end of said arms either being
formed or having parts attached formed in the shape of a segment of a circle of which
the joint would be the centre, the segmental parts are so placed on arms as to secure
globe or shade by segmental part or parts being turned on joints so as to pass into
inside of opening in globe or shade, in a gas globe holder which is usualy made with
three arins to hold a comet globe, two of the segmental parts may be secured to or
from part of the arms, one arm only carrying a seginental part jointed to the side of
arm either by an eyelet or other suitable joint, the segmental part or arm of
segmental part may have a projection which by the spring of arm will pass over part
of holder arm and spring into a corresponding indentation or hole in arm of holder, to
keep segment in position electric light globes or shades may be suspended in a similar
manner or the segmental parts may be all moveable and passed down seperately in a
similar manner into opening in top of globe or shade and thus secure or carry them
suspended from holder or the segmental parts may be so arranged that when a globe
or shade is pushed up against them they are lifted up until the ends of segments
enters the opening in globe or shade and may either fall down into globe or shade by
their own weight or be assisted by a spring or equivalent and may be opened or closed
by a lever operating a sliding piece or tube central with holder and having projections
to engage with and operate all the segmental pieces or be connected to segmental
pieces to operate them at one time by levers or their equivalents or outside of
segmental pieces may have teeth cut round to engage with corresponding teeth upon
a sliding piece or tube arranged to be lifted by the hand or by a lever, one end of
lever which moves the sliding piece being made to project from holder and arranged
so that one movement of lever may either secure or unfasten the globe or shade by
operating all the segmental pieces together.

COMPLETE SPECIFICATION.
Improved Holder Fastenings to Secure Globes or Shades for
Lighting Purposes.
JOHN HOWARD Ross, 209, Villa Street Birmingham, Lighting Engineer, and
EDWARD ELIJAH ATKINS, 19, Villa Grove, Villa Road, Birmingham, Chandelier
Manufacturer, 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 object of our invention is to provide a simple method of securing either gas or
electric globes or shades to their fittings or holders, and may be used to secure a globe
or shade either resting on or suspending from said holders or fittings, either one or
more arms are jointed to said holders or fittings, the ends of said arms either being

page_text: formed or having parts attached formed in the shape of a segment of a circle of
which the joint would be the centre, the segmental parts are so placed on arms
as to secure the globe or shade by segmental part or parts being turned on joints
so as to pass, into inside of opening in globe or shade, in a gas globe holder which
is usualy made with three arms to hold a comet globe, two of the segmental
parts may be secured to or from part of the arms, one arm only carrying a
segmental part jointed to the side of armi either by an eyelet or other suitable
joint, the segmental part or arm of segmental part may have a projection which
by the spring of arm will pass over part of holder arm and spring into a corre-
sponding indentation or hole in arm of holder, to keep segment in position electric
light globes or shades may be suspended in a similar manner or the segmental
parts may be all moveable and passed down seperately in a similar manner into
opening in top of globe or shade and thus secure or carry them suspended from holder
or the segmental parts may be so arranged that when a globe or shade is pushed up
against them they are lifted up until the ends of segments enters the opening in globe
or shade and may either fall down into globe or shade by their own weight or be
assisted by a spring or equivalent and may be opened or closed by a lever operating a
sliding piece or tube central with holder and having projections to engage with and
operate all the segmental pieces or be connected to segmental pieces to operate them
at one time by levers or their equivalents or outside of segmental pieces may have
teeth cut round to engage with corresponding teeth upon a sliding piece or tube
arranged to be lifted by the hand or by a lever, one end of lever which moves the
sliding pieces being made to project from holder and arranged so that one movement
of lever may either secure or unfasten the globe or shade by operating all the
segmental pieces together.
With reference to the accompanying drawings, the same letters indicate the same
parts in the different figures.
Figure I is an arm of a gas or other globe holder to which our improved segmental
fastener is to be applied.
Figure II shews the segmental lever fastener before it is attached to arm.
Figure III shews the fastener attached to arm in position to receive globe.
Figure IV shews the fastener on arm of a holder in position to hold or secure globe
or shade on the inside.
The arm figure I is secured at A by soldering or otherwise to an ordinary centre or
socket such as is commonly used for globe holders and has the hole B pierced in it to
receive the eyelet or rivet which passes through the hole B in Figure II to secure the
lever to arm and form a pivot for lever to work on, the top and bottom part of lever
at C and D as indicated by dotted lines are bent over at right angles so as to stop the
upward and downward motion of lever at the proper place and a projection E on lever
pressing into hole F on arm holds lever in position on arm.
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
do claim is
1st. The application to and combination with the arm or arms of holders for globes,
shades &c., of a lever so formed that the part going into globe to secure it to holder is
formed or shaped as the segment of a circle whose centre is the fulcrum on which said
segmental lever works so that the pull of globe against the inner part of segmental
lever will be directly against the fulcrum, a projection on lever or other mechanical
equivalent being used to hold the lever in position substantially as described and as
illustrated in the accompanying drawings.
