PROVISIONAL SPECIFICATION.
Improvements in the Means of Attaching Lamp Globes, Shades,
and the like.
I, FELIX EDWIN BATEMAN, of No. 119, Steelhouse Lane, in the City of Birming-
ham, Gas Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention is mainly applicable to the attachment of globes or shades of glass
or other material to gas, incandescent, electric, or other lamps and consists of new
or improved devices for attaching same to the upper metallic gallery or collar.
Inside the latter I place a ring of spring wire which in its normal position enters
or engages with a groove formed round the top of the globe or shade, and clips
it firmly. This ring of spring wire is by one method secured by a stud passing
through a hole or slot in one side of the gallery or collar and is divided and over-
lapped and the ends turned outwardly through an opening or wide slot on the
other side so that when the projecting ends are pressed together with the fingers
the ring is opened and the globe or shade released. This invention is also
applicable for carrying globes or shades from the bottom and also to galleries or
collars for suspending or supporting globes or shades from the inside, the ring of
spring wire being on the outside of the gallery or collar. In the latter case the
ends of the wire are simply turned upwards without overlapping and the globe
or shade is released by the pressure of the fingers as before. The ends of the ring
of spring wire may be rounded or looped or fitted with studs or otherwise as pre-
ferred.
I prefer to make the gallery or collar with an internal or external groove in
which the ring of spring wire rests in position, and instead of one stud opposite
the open or operating side of the ring of spring wire I may use two, three, or more
such studs or other supports, or the ring may be divided into sections for very
large globes or shades.
My invention is also obviously applicable to the attachment of such bowls or
globes as are used with regenerative lamps, eye screens on gas pendants or for
clipping Comet globes, Argand chimnies, or to the globes or shades of other
like articles.

܂
My invention is mainly applicable to the attachment of globes or shades of glass
or other material to gas, incandescent, electric, or other lamps and consists of new
or improved devices for attaching same to the upper metallic gallery or collar.
Inside the latter I place a ring of spring wire which in its normal position enters
or engages with a groove formed round the top of the globe or shade and clips
it firmly. This ring of spring wire is by one method secured by a stud passing
through a hole in one side of the gallery or collar and is divided and over-
lapped and the ends turned outwardly through an opening or wide slot on the
other side so that when the projecting ends are pressed together with the fingers
the ring is opened and the globe or shade released. This invention is also
applicable for carrying globes or shades from the bottom and also to galleries or
collars for suspending globes or shades from the inside, the ring of spring wire
being on the outside of the gallery or collar. In this case the ends of the wire
are simply turned upwards without overlapping and the globe or shade is released
by the pressure of the fingers as before. The ends of the ring of spring wire may
be rounded or looped or fitted with studs or otherwise as preferred.
I prefer to make the gallery or collar with an internal or external groove in
which the ring of spring wire rests in position, and instead of one stud opposite.
the open or operating side of the ring of spring wire I may use two, three, or more
such studs or other supports, or the ring may be divided into sections for very
large globes or shades.
My invention is also obviously applicable to the attachment of such bowls or
globes as are used with re-generative lamps, eye screens on gas pendants or for
clipping Comet" globes, Argand chimnies, or to the globes or shades of other
like articles.

In the three accompanying sheets of explanatory drawings to be hereinafter
referred to:
Figures and 2 Sheet 1 shew respectively a vertical section, and a plan of one.
form of globe or shade attachments arranged in accordance with my invention.
Figures 3 and 4 Sheet 2 shew in elevation and in horizontal section a modified,
arrangement of devices.
Figures 5, 6, and 7 Sheet 3 shew other modifications of my globe or shade
attachments.
In Figures 1 and 2 A is the upper part of a lamp globe or shade with groove (a).
arranged around it externally or other equivalent recess or collar. B is the
gallery for supporting the globe or shade with brackets (b) of any usual design, but
in accordance with my invention made preferably with the annular groove (6)
for combination with the improved devices now to be described. O is a ring of
wire of steel, hard brass, or other suitable material of an elastic nature made to
overlap as shewn at (c). The ends (2) may be looped or have studs as shewn,
This ring in its normal position engages with the groove (a) as shewn at (³) and
is carried or supported in the gallery B by the studs D passing through slots (d)
which are wide enough to allow side play of the studs as shewn. (2) is a longer
slot through which the enus (²) pass. In this position the globe or shade is
securely held to the gallery of the lamp, but is easily released for removal by
pressing together the loops or studs at (2) thus expanding the ring C to the
diameter shewn at (c) Figure 1.
A is the top
I will now describe the modification shewn in Figures 3 and 4.
of the globe or shade which in this case may be made to rest on the ring Cas
shewn. B is the gallery of any usual design or material with an annular
groove (2) arranged internally. The studs D on the ring C and the ends (2) are
also arranged internally, the latter being preferably turned upwards as shewn and
finished with loops or studs for operating same as before.
The action is thus
simply reversed. By pressing (²) (²) the ring C is contracted and the globe or
shade released:

page_text: In the modification of my invention shewn in elevation and plan in Figures 5
and 6, the gallery shewn in the previous figures is dispensed with and the ring C
connected directly by arms or brackets (b) to the supporting socket (6). A semi-
tubular sheath E may be fixed on the ring at (e) and sliding over the ring at (e¹)
for keeping the ring in a true plane. The ring in this case operates by contrac-
tion similarly to the arrangement in Figures 4 and 5.
Figure 7 shews in plan an arrangement for carrying the globe chimney or shade
from the bottom with direct connection as in Figures 5 and 6 but with the ring C
overlapped at ends for operating by expansion.
The ring C may be made of any section of metal or varying or tapering over
certain portions of the circumference or may be made slightly elliptical
on plan,
so that when operated it assumes a more nearly circular shape. The gallery B
instead of having groove (62) as shewn in Figures 1 to 4 may consist of a plain
circular belt through which the studs 1) and the ends (2) of the ring C pass in
suitable holes or slots.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:―
(1) The construction of attachments for lamp globes, shades and the like with
elastic ring C in combination with grooved galleries and supporting studs 1) and
of the devices shewn or equivalent devices for operating either by expanding or
contracting movements the ring C substantially as and for the purposes herein-
before described and set forth.
(2) The construction of such attachments with the elastic ring in direct con-
nection with the central support by the arms or brackets (b) or equivalent devices
substantially as and for the purposes hereinbefore described and set forth.
Dated this 12th day of October 1898.
