A New or Improved Globe-shade for use in connection with Gas
"Lamps, Oil Lamps, and the like.
I, SARAH GROSVENOR BLOCKLEY, of 8, Old Park Villas, Palmer's Green, N.,
no calling, do hereby declare the nature of this invention to be as follows:-
My invention relates to a new or improved device, more particularly intended
for use in connection with gas lamps, oil lamps and the like, the object being
to provide
a shield or screen mounted or carried upon the globe of the lamp in
such a manner as to allow of it being turned to any required part of the globe
for the purpose of screening or shading the light in any required direction and
this device will be found particularly useful in sick rooms, sleeping apartments
and the like.
In carrying my invention into practical effect, the improved device comprises
a suitable disc forming a screen or shield shaped to correspond with the outer
surface of the globe. To this screen or shield is secured an arm, the lower
extremity of which projects in a downward direction and is suitably connected
with a wire ring, secured around the lower rim of the shade, in such a manner
as to allow of the aforesaid projecting arm travelling or passing around the globe
so as to bring the screen or shield to any required point.
The screen or shield may be constructed of any suitable material, while its
inner surface, designed to come against the globe may be a reflecting or non-
reflecting surface as required.

A New or Improved Globe-shade for use in connection with Gas
Lamps, Oil Lamps, and the like.
I, SARAH GROSVENOR BLOCKLEY, of 8, Old Park Villas, Palmer's Green, N.,
no calling, 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:-
My invention relates to a new or improved device for use in connection with
gas lamps; oil lamps, electric lamps, and the like, the object being to provide

page_text: a shield or screen mounted or carried upon the globe or lamp or arranged closely
in connection with it in such a manner as to allow of its being turned to any
required point for the purpose of screening or shading the light in that direction,
and this device will be found particularly useful in sick rooms, sleeping apart-
ments and the like.
In order that my invention may be fully understood, I will now proceed to
describe same with reference to the accompanying drawings in which:.
Fig. 1 is a back view of a shade shown applied to a globe, illustrating one
method of carrying this invention into effect.
Fig. 2 is a side elevation of the shade and shade carrier detached from the
globe, and
Fig. 3 is a plan of the shade carrier..
Fig. 4 illustrates in side elevation and Fig. 5 in plan a shade and attachment
particularly applicable to oil lamps, gas lamps and other lamps in connection
with which a chimney or glass is employed.
Figs. 6 and 7 illustrate in side elevation and plan a shade and carrier designed
for use in connection more particularly with electric glow lamps.
According to this invention and as shown in Figs. 1 to 3, the shield or screen a
consists of a suitable disc of metal or other material formed to correspond in
shape with the outer surface of the globe. This disc is preferably secured to a
wire arm 6 formed integrally with a ring & surrounding the lower rim e of the
globe d, and for this purpose the disc a is furnished with an upstanding strip f
beneath which the arm passes, and in this manner the disc a, forming the
screen or shield, is capable of being turned around the outer surface of the globe d
in such a manuer as to screen the light at any required point.
In the modified form of the device shown in Figs. 4 and 5, a circular band
of metal or other suitable material is provided, and which is capable of being con-
tracted by means of a screw g¹, which passes through the lugs g² formed by the
outwardly turned extremities of the ring or band g.
The rings or band, g is provided with an extension g³ furnished with a radial
or concentric part h, to which the shield or screen a is permanently secured. A
shield or screen of this description is intended more particularly for use in con-
nection with a gas, oil or other lamp furnished with a plain upright glass or
chimney, while where a glass or chimney of any other description is employed,
the said screen or shield a must be shaped accordingly to conform to the contour
of the glass or chimney. This shade is secured in position by the ring or band g
which is arranged just beneath or surrounding the pronged gallery supporting
the glass or chimney, where it is secured in place by a screw g', the said band
or ring being tightened to such an extent as to allow of the screen or shield being
turned to any required point without becoming detached from the lamp.
A similar method of attachment is employed in connection with the shield or
screen shown at Figs. 6 and 7 and which is particularly designed for use in con-
nection with electric glow lamps. In this case a similar ring or band g is pro-
vided capable of being tightened by means of a screw gl passing through the
lugs or outwardly turned extremities 2 of the ring or band g. The ring or
band 9 carries an outwardly projecting arm m the extremity of which is bent
upwards at right angles and to this extremity the shield or screen a is secured by
means of a set screw n which passes through a socket or clamping piece p and
bears against the arm m, and in this manner the shield or screen a, in addition
to its turning movement, is capable of vertical adjustment in the manner
described.
In addition to the use of these shades in sick rooms, bed rooms, night nur
series, and other places of this description, they may with advantage be employed
in hospitals, reading rooms and offices, and also in shop windows and picture
galleries and other places of this description where the light is required to be
directed to certain points, and to be screened from others, furthermore, the inner
surface of the screen or shield may be sufficiently polished, plated or treated in

page_text: any other suitable and convenient manner, so as to enable it to fulfil the double
purposes of a screen or shield and a reflector, while in all cases the screens or
shields are capable of being easily attached and detached as required.
I do not restrict myself to the exact method of mounting and securing the
screen or shield, described as shown in the drawings, the essential feature being,
to mount or arrange a screen or shield in connection with a lamp in such a
manner that it is capable of being readily turned to any required point.
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 arrangement of a screen or shield such as a, suitable shaped to conform
to contour or outline of the lamp globe or glass in connection with which it is
employed, upon an upwardly projecting arm 6 formed integrally with a ring c
or upon an extension g³ of a ring or band g or upon an arm projecting from such
a ring or band, in such a manner that the said screen or shield may be mounted
upon, or in connection with, an oil, gas, electric or other lamp, so as to allow of
its being readily moved to any required point; substantially as herein described
and shown, and for the purposes specified.,
2/. The combination with an oil, gas, electric or other lamp, of a movable shield
or screen substantially as set forth.
