"
The object of this Invention is to provide gas and other globes with a reflector
which also answers the purpose of the "consumer or top" frequently placed on
gas globes to prevent the blackening of the ceiling. The advantages of this reflector
are, (1) That it can be fitted to globes of different sizes; (2) It economises the light
by throwing downward and horizontally the upward rays; (3) It is not liable to
break like the ordinary "consumers"; (4) It prevents the blackening of surrounding
objects.
The accompanying drawings show examples of the Invention. In Figures 1
and 2 it is shown in section as applied to gas globes of different forme. Figures 3
and 4 show top views of the two parts of the reflector. Figure 5 is a sectional
elevation, and Figure 6 a plan of a modification of the reflector. Figures 7 and 8
are similar views of another modification.
In Figures 1. 2. 3 and 4 the reflector is made in two parts, an annular band or
crown a and the reflector b. The crown a is a band of sheet metal bent to the
form shown, its ends overlapping without being united to enable it to fit globes of
different shapes and sizes. It is formed with a rebated lip or flange which is
sprung into the aperture of the globe and is retained by its own elasticity.
parts a and b may be made of metal or other material. They are connected
together by two pins e on b-entering holes fin a. These holes may either be

example. The two parts have perforations g to permit the draught necessary for

ALEXANDER MELVILLE CLARK of the firm of A, M, and W, Clark of

The object of this Invention is to provide globes which surround gas and other
flames with a reflector which also answers the purpose of the consumer or top
frequently placed on gas globes to prevent the blackening of the ceiling. The
advantages of this reflector are (1) That it can be fitted to globes of different
sizes; (2) It economises the light by throwing downward and horizontally the
upward rays; (3) It is not liable to break like the ordinary "consumers"; (4) It
prevents the blackening of surrounding objects.
The accompanying drawings show examples of the Invention. In Figures 1 and 2
it is shown in section as applied to gas globes of different forms. Figures 3 and 4
respectively show top views of the two parts of the reflector. Figure 5 is a
sectional elevation, and Figure 6 a plan of a modification of the reflector. Figures 7
and 8 are similar views of another modification.
In Figures 1. 2. 3. and 4 the reflector is made in two parts, an annular band or
crown a and the reflector b. The crown a is a band of sheet metal bent to the
form shown, its ends overlapping without being united to enable it to fit the tops
of globes c of different shapes and sizes. It is formed with a rebated lip or flange d
which is sprung into the aperture of the globe and is retained by its own elasticity.
The parts a and b may be made of metal or other material. They are connected
together by two pins e on b entering holes fin a. These holes f may either be
oval, or there may be a number of holes so that there shall always be two to receive
the pins e, diametrically opposite one another in the various adjustments of the
crown a to suit globes of different sizes, or other means of attachment may also be
employed such as clips passed through the holes and then bent down, or a bayonet
joint for example. The two parts a and b have perforations g to permit the
necessary draught for the flame.
In Figures 5 and 6 the overlapping ends of the expanding ring or crown a are
united by a screw pin fixed in one end passing through a slot b in the other end
and secured by a binding nut c. d are studs to facilitate the adjustment. e is the
reflector which in this case is hinged or otherwise jointed at f to a so as to enable
it to be thrown back, as shown in dotted lines in Figure 5, for the purpose of
cleaning the interior.
In Figures 7 and 8 the reflector e also works on a hinge as before, but in this
case it is supported at a short distance above the part a by small legs g rising
therefrom as shown. The hinge f is rivetted or otherwise fixed to the part a and
is formed with an extension h so as to support the reflector out of contact with the
globe when turned back, as shown in dotted lines in Figure 7. As in this case the
reflector does not rest directly upon the crown, the air holes g provided in the former
case are not required.
The form and arrangement of the various parts may be varied without departing
from the Invention.
Having described the nature of the said Invention and the manner of performing
the same,
I declare that what I claim as the Invention to be protected by the
herein before in part recited Letters Patent is.
A reflector for gas and other globes constructed of a loose expanding ring or

page_text: crown fitting on the top of the globe, and of a reflector connected to said ring by pins
or hinged thereto and resting either close down upon, or at a short distance above,
said ring or crown, substantially as herein before described and shown in the
drawings.
In Witness whereof I the said Alexander Melville Clark have hereunto set
my hand and seal this twelfth day of April, A.D. 1883
