COMPLETE DE PULFICATION,
Improvements in Lanterns or Globes Chiefly for Incandescent Gas-
lights, Arc Electric Lights, and the like.
SIMON BIHELLER, Merchant, of 70 and 71, Chiswell, in the City of London,
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 improvements in lanterns or globes chiefly intended
for use with incandescent gas lamps and arc electric lights but suitable for all
cases where a shade or glass globe is to be raised and lowered from time to time
whilst remaining attached to the framing that carries it.
This invention is illustrated in the accompanying drawings that show in
Fig. 1 a sectional elevation of an incandescent gas lamp to which the same is
applied, Fig. 2 being a detail.
with the burners a a as usual.
One
In said drawing A, is the central tube carrying the whole lamp, being fitted
To this tube is attached in any convenient manner
the top B of the lantern. The part B by the arms bb carries the upper metal
portion C of the lantern proper. D is the glass part or globe of the lantern and
this is suspended in the manner presently set forth. In the top B, I provide
arms c c fitted with rollers d d over which run cords chains or the like e e.
end of these cords or the like e e is connected with a ring E E of sufficient weight
to counterbalance the moving parts of the lantern. The other end of the
cords e e passes over rollers ff which are fixed on the same spindles as corre-
sponding rollers 9 g. These rollers g g are of much larger diameter than the
rollers ff. The bearings for the spindles carrying the rollers are provided in
the brackets h h fixed on the metal portion, or top of the lantern. Over the
rollers pass cords or the like e¹ e¹ the free ends of which are attached to the
hooks FF. The hooks F F are of the peculiar shape shown and adapted to pass
through holes or recesses in the ring G. H is the glass portion or globe of the
whole. It will be noticed in the drawing that the ring E has recesses to allow
it to pass over the rollers 7 g when necessary.
The operation of this invention is as follows:-When the parts are in the
position shown in Fig. 1 the moving portion is at its highest position and the
lantern is closed. When access to the interior is desired for any reason, say
for cleaning renewing carbons, or mantles, as the case may be, the movable part
is pulled downwards. When this is done a portion of the cords e¹ e¹ is unrolled
from the large rollers g g and this causes the rollers g g and with these the
rollers ff to revelve. The cords e e¹ are wound on the rollers g g in one
direction and the cords e e are wound on the rollers f f in the opposite direction
and consequently as the cords e¹ el are wound off, the cords e e are wound up on
the rollers ff, so that, when the body or moving part of the lantern descends,
the ring E ascends and vice versa; as however the rollers f f are smaller than
the rollers g g the distance through which the ring E travels is always consider-
ably smaller than that through which the globe is raised, or lowered, so that

page_text: the movement of the ring E that serves as a counter-weight, partly balancing
the globe, is confined within the metal top. The glass part or globe rests on the
bent part of the hooks F F when in position and the heavier the globe is, the
greater pressure it will exert on the hooks and thus the more securely it will
remain in place. If it is desired to remove it, the cords e e¹ are slackened and
the hooks FF turned until they are in the position illustrated in Fig. 2 and
the globe will then readily pass the hooks and leave the ring G.
I have already pointed out that this invention is applicable to of all kinds of
lamps or lanterns and not only to incandescent gas lamps as illustrated in the
drawings, and I further point out that the details of construction may be varied
without departing from the spirit of this invention, thus there may be three or
more sets of rollers and there may be cords or chains to support the moving
parts. The manner in which the glass part is connected with the ring G may
also be different from that shown.
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:
-
As a means for permitting the moveable parts of a lantern to be readily raised
and lowered, and for counter balancing such moving parts, rollers of large
diameter (such as gg) rigidly connected with rollers of small diameter) such
as f f) so that the two pairs of rollers rotate together, a counter-weight being
suspended from the cords on the small rollers and the moving parts of the lantern
being suspended from the cords on the large rollers, the cords on the large rollers
being wound in a direction opposite to that in which the cords on the small
rollers are wound, all combined and operating substantially as set forth and
illustrated in the drawings.
