PROVISIONAL SPECIFICATION.
Improvements in and connected with Electrical Incandescent
Lamps.
I, HENRY COOPER of 7 Mersey Road, Ashton-on-Mersey, in the County of
Chester, Commercial Traveller, do hereby declare the nature of this invention to
be as follows:-
This invention relates to globes, shields, glasses and the like and the means and
devices for connecting them with the holders of electrical incandescence lamps.
In or upon the lamp holder I arrange two or preferably three or more claws
which may be formed or secured in or upon a plate or a reflector or the like
equivalent for the ordinary gallery now used for connecting globes and the like
with the lamp. Upon the mouth or that part of the globe or the like which is
next, the lamp holder in use, I form a flange through which there are as many slots
as there are claws, so that the claws which are connected with the lamp holder.
may pass through the slots, and, when the globe or the like is slightly turried,
under the flange. In the under side of each section of the flange contained
between two slots, I form a recess adapted to receive the end of the claw coming
under that section. Hence, when the globe or the like is put upon the lamp, it is
first pushed upwards, allowing the claws to pass the slots, next, turned through a
small angle so as to bring the points of the claws under the flange, and
finally it is lowered to bring the ends of the claws into the recesses.
the like must therefore be first lifted then turned and lowered before it can he
removed, so that it is unlikely to be accidentally displaced. There being also no
screws, the globe or the like may be much more quickly removed and replaced
than when the ordinary gallery and screws are employed.
The globe or
The arrangement described is applicable for pendant lamps. When the lamps
have to occupy any other position in use, I arrange a spring or springs in such
position or positions that it or they will tend to force the globe or the like away
from the lamp holder.

1, HENRY COOPER of 7 Mersey Road, Ashton-on-Mersey in the County of
Chester, Commercial Traveller, 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 :-
This invention relates to globes, shields, glasses and the like and to the means
and devices for connecting them with the holders of electrical incandescence
lamps.
the lan hold

page_text: preferably three or more claws, which may be formed or secured in or upon a plate,
dome, reflector or the like equivalent for the ordinary gallery now used for con-
necting globes and the like with the lamp. Upon the mouth or that part of the
globe or the like which is next to the lamp holder in use, I form a flange through
which there are as many slots or ways as there are claws, so that the claws, which
are connected with the lamp holder may pass through or along the slots or ways,
and, when the globe or the like is slightly turned around its axis, under the flange.
In the under side of each. section of the flange contained between two of the slots
or ways, I form a recess adapted to receive the end of the claw coming under that
section. Hence when the globe or the like is put upon the lamp, it is first pushed
upwards, allowing the claws to pass the slots or ways, next, turned through a
small angle so as to bring the points-of-the-claws under the flange, and finally, it
is lowered to bring the ends of the claws into the recesses. The globe or the like
must therefore be first lifted and then turned and lowered before it can be removed,
so that it is unlikely to be accidentally displaced. There being also no screws, the
globe or the like may be much more quickly removed and replaced than when the
ordinary gallery and screws are employed.
The arrangement described is applicable for pendant lamps. When the lamp
has to occupy any other position in use, I arrange a spring or springs in such a
position or in such positions that it or they will tend to force the globe or the like
away from the lamp holder.
The accompanying drawings illustrate in what manner I may carry my invention
into effect.
Figure 1 represents partly in elevation and partly in section one of the improved
glasses when in use.
Figure 2 is a plan of the top edge of one of the glasses.
In the arrangement illustrated I have indicated a dome as the means for
connecting the globe with the lamp holder, but it will be understood that I do
not limit myself to this appliance, nor to the particular shape or construction of
the glass or globe represented.
Lis the lamp holder, and G the globe or glass employed to surround or protect
the lamp. Dis the dome by means of which and the claws C thereon the globe G is
connected with the holder. F is the flange formed around the outside of the
opening of the globe, through which the slots or ways. W are formed for the
passage of the claws. This flange may however be formed if desired on the inner
edge of the opening. R is the recess formed on the under side of each section of
the flange for the reception of the end of the appropriate claw as herein before
described.
When the globe or the like is in any other than a pendant position in use, or in
all cases if desired, springs S, connected with the lamp holder and pressing upon
the top edge of the globe or the like may be used.
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 :-
1. The herein before described method of and means for connecting globes and
the like with electrical incandescence lamp holders, substantially as set forth and
as illustrated by the accompanying drawings.
2. In globes glasses and the like for electrical incandescence lamps, a flange
around the opening therein, said flange having transverse slots or ways formed
therein and a recess under each section of the flange, substantially as and for the
purpose herein before described and as illustrated by the accompanying drawings.
