Improvements in and connected with Holders for Glass Globes and
Shades of Gas and other Lights.
I, WILLIAM BEAL, of Hill Street, in the City of Birmingham, Lamp and Gas
Fittings Manufacturer, do hereby declare the nature of this invention to be as
follows:
This invention consists of the herein described improvements in and connected
with metallic holders for glass globes and shades of gas and other lights such
for instance as oil lamps and electric lights. My improvements are applicable
to globe and shade holders of all kinds and particularly to those of the kind
described in the Specification of my prior Letters Patent No. 8391 of A.D. 1885.
It is well known that when glass globes and shades are held by the said
metallic holders the said glass globes and shades are when expanded by the heat
of the light often broken through the screws or jaws or gripping or holding
parts of the holder bearing too hard against the glass globe or shade.
The object of my invention is to make the gripping or holding parts of the
globe or shade holders or other parts of the same which come in contact with the
glass elastic or yielding to a certain extent so as to allow of the expansion of the
globe or shade and prevent the breaking of the same.
In carrying out this invention the fixing screw ends or the jaws or prongs
or other metal parts of the globe holder or shade holder which come in contact
with the glass globe or shade are coated or covered or partly coated or covered
with indiarubber which being to a certain extent yielding and elastic will allow
of the expansion of the glass globe or shade and prevent the breaking of the
same. The said indiarubber parts may be fixed to the metallic parts of the
globe holder or shade holder or to the end of the screw or screws of the same in
various ways. The indiarubber may for instance be made in the form of small
pieces of indiarubber tube which are threaded on to the prongs or jaws or other
metal parts of the globe or shade holder or on to the screw end of the same or the
indiarubber may be made in the form of small caps or bearing blocks of various
shapes as may be found most convenient to fix to any of the parts of the said
globe holders or shade holders which come in contact with the glass.

Improvements in and connected with Holders for Glass Globes and
Shades of Gas and other Lights.
I, WILLIAM BEAL, of Hill Street, in the City of Birmingham, Lamp and Gas
Fittings Manufacturer, do hereby declare the nature of this invention and in
[Price 8d1

page_text: what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention consists of the herein described improvements in and connected
with metallic holders for glass globes and shades of gas and other lights such
for instance as oil lamps and electric lights. My improvements are applicable
to globe and shade holders of all kinds and particularly to those of the kind
described in the Specification of my prior Letters Patent No. 8391 of A.D. 1885.
It is well known that when glass globes and shades are held by the said
metallic holders the said glass globes and shades are when expanded by the heat
of the light often broken through the screws or jaws or gripping or holding
parts of the holder bearing too hard against the glass globe or shade.
The object of my invention is to make the gripping or holding parts of the
globe or shade holders or other parts of the same which come in contact with the
glass elastic or yielding to a certain extent so as to allow of the expansion of the
globe or shade and prevent the breaking of the same.
In carrying out this invention the fixing screw ends or the jaws or prongs
or other metal parts of the globe holder or shade holder which come in contact
with the glass globe or shade are coated or covered or partly coated or covered
with indiarubber which being to a certain extent yielding and elastic will allow
of the expansion of the glass globe or shade and prevent the breaking of the
same. The said indiarubber parts may be fixed to the metallic parts of the
globe holder or shade holder or to the end of the screw or screws of the same in
various ways, as I will now describe by referring to the accompanying drawings
on which Fig. 1 is a side elevation of a glass globe holder of the kind described
in the Specification of my prior Letters Patent No. 8391 of A.D). 1885 but with
the gripping or holding part provided with an indiarubber contact piece in
accordance with my present invention; Fig. 2 shews separately the gripping
part of the globe holder illustrated by Fig. 1; Fig. 3 shews another kind of
glass globe and globe holder with the gripping screws constructed in accordance
with this invention; Fig. 4 illustrates my invention applied to a glass shade
holder for a gas light; Fig. 5 shews separately on an enlarged scale one of the
gripping screws of the globe and shade holders illustrated in Figs. 3 and 4; and
Fig. 6 shews a modified form of the end of the said gripping screw.
The same letters of reference indicate the same or corresponding parts in all
the figures of the drawings.
Referring firstly more particularly to Figs. 1 and 2, A is the gripping part
of the globe holder which by the turning of the screw B is caused to grip against
the base of the globe C. According to my present invention the part of this
gripping piece A which would come in contact with the glass is covered with an
indiarubber piece I which in this form of my invention is a short piece of india-
rubber tube slipped on to the upper part of the holder A which latter is or may
be made with two shoulders a¹ a² to keep the indiarubber D in place. The india-
rubber piece D coming in contact with the glass effectually prevents the same from
I find it is not
being broken by the screw B being screwed up too tightly.
necessary to coat or cover the grippers e of the other two arms E of the globe holder
with indiarubber as if the moving gripper or holder A is provided with an india-
rubber pad D as above described this will as above described effectually prevent
the globe from being broken by the gripping part D being screwed too tightly
against the same.
In the arrangement of my invention shewn by Fig. 3 the fixing screws F
which go through the globe holder and take against the neck of the glass globe
are each provided with an indiarubber pad or tip G which projects for a short
distance at the front of the screw so as to come in contact with the glass when the
screws are screwed up and thus afford a yielding contact which will allow of the
expansion of the glass and prevent the same from cracking. This indiarubber
pad can as shewn in Fig. 5 be conveniently made like a small indiarubber

page_text: block which is cemented or other wise fixed in an axial hole in the front of the
screw. In Fig. 6 the indiarubber pad is marked G₁ and is made in the form of
an indiarubber cap which covers the reduced end of the screw and is secured
thereto by cement or other suitable means.
It will be evident that the indiarubber blocks or bearing pieces may be made
in other forms and secured to the fixing screw end or to the jaws or prongs or
other metal gripping parts of the globe holders or shade holders in other ways
than those illustrated without departing from the nature of this invention.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:-
1. In a holder for glass globes and shades of gas and other lights, the applica-
tion and employment of indiarubber on the tips or gripping surfaces of the part
or parts by which the globe or shade is held so arranged as to allow the glass
globe or shade to expand and thus prevent the same from breaking, substantially
as described.
2. A holder for glass globes and shades of gas and other lights, having its
gripping or holding part or parts which come in contact with the glass coated or
covered or partly coated or covered with indiarubber substantially as and for
the purpose described.
3. A gripping or binding screw for the holders of glass globes and shades of
gas and other lights, made with an indiarubber tip adapted to come against the
glass globe or shade when the fixing screw is in use substantially as herein before
described.
Doted this 3rd day of December 1898.
