Improvements in Lamp, Chandelier, or the like Fittings.
We, EDWARD THOMAS READ, of 75, Thornhill Road, Handsworth, Staffordshire,
Brassfounder's Manager, and ALFRED HENRY GRIFFITHS, of Surrey Works, Smeth-
wick, Staffordshire, Managing Director, do hereby declare the nature of this inven-
tion to be as follows:-
This invention relates to improvements in lamp, chandelier and the like fit-
tings, and is intended chiefly to accommodate incandescent light fittings, but part
or parts of which may be applied to lamps of other form or construction, or their
accessory parts, and its primary object is to provide improved means whereby the
screens or eye shades for such lights may be more conveniently carried than
hitherto, or removed at will; also improved facilities for carrying ornamental
scrolls or the like, from such fittings (including their burners) both of which pur-
poses may be effected without fixed attachments or other interference with the
down rods or stretchers, or other rods used in their construction.
In carrying out our invention we proceed as follows:-
-
Referring to what are known as down-hanging lamps, as is well known the
burner is carried at the lower end of, and between two down rods or stretchers.
Such burners are usually made with three wing-like projections equi-distant
around their sides and also with a horizontal circumferential flange or rib. We
therefore provide a ring or the like which serves as a base upon which is carried
the screen. This ring encircles the stretchers, or in some cases it may lie within
the said stretchers. Upon the underside of this ring, are three grooved projections
to correspond with and fit upon the three wings upon the burner, so that the said
ring may he carried thereon. In some cases we may provide three projections
upon the ring which shall rest upon the flange or rib or other part of the burner,
and one or more of such projections may consist of screw pins so that they may be
sufficiently withdrawn-where necessary-to permit of the upward passage of the
ring, and afterwards be re-adjusted to their proper position; or one or more of
such projections may consist of levers or spring slides which shall yield to, the
upward direction of the ring, but require being held back to permit of the down-
ward removal of the said ring, or in other cases the said ring may not have the
said projections &c., but be removably passed downwards on to the burner.
In some cases we may provide stretchers or down rods from the ring which
shall converge to the centre at the bottom of the fitting and be there screwed to
and thus carried from, the said fitting. In some cases we may provide upon the
ring (exteriorly or interiorly) two or more spring clips which may be pushed on
to the rods, having sufficient holding power to support the necessary weight.
We may now provide for ornamentation by means of this or a similar, or an
independent ring, (as hereinafter mentioned) as follows:-To the said rings may
be attached, removably or fixed, scroll or scrolls or the like ornamentation which
may be made to conform with the general design of the fitting, or as before inti-
mated, we may carry such a ring in some cases upon the top of the screen itself,

page_text: or in other cases such ring for carrying the said ornaments may be attached to
the down rods by spring clips as before described, but at any desirable position
independent of the screen, while in other cases a ring having the ornaments may
be removably carried upon any suitable part of the burner.
By these means a screen may be used without any additional fixed attachments
to the said stretchers and in which the said ring or similar rings also furnish a
ready and convenient means of carrying ornamental parts as described.

Improvements in Lamp, Chandelier, or the like Fittings.
We, EDWARD THOMAS READ, of 75, Thornhill Road, Handsworth, Staffordshire,
Brassfounder's Manager, and ALFRED HENRY GRIFFITHS, of Surrey Works, Smeth-
wick, Staffordshire, Managing Director, do hereby declare the nature of this inven-
tion 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 lamp, chandelier, and the like fit-
tings, and is intended chiefly to accommodate incandescent light fittings, but part
or parts of which may be applied to lamps of other form or construction, or their
accessory parts, and its primary object is to provide improved means whereby the
screens or eye shades for such lights may be more conveniently carried than
hitherto, or removed at will; also improved facilities for carrying ornamental
scrolls or the like from such fittings, including their burners, both of which pur-
poses may be effected without fixed attachments or other interference with the
down rods or stretchers, or other rods used in their construction.
We attain these objects by the means illustrated upon the accompanying draw-
ings, upon which :-
Fig. 1, gives a general view of this our invention adapted to a fitting having
an incandescent gas burner.
Fig. 2, is a plan view, and Fig. 3, a sectional view (on line A-B of Fig. 2)
of the supporting ring hereinafter described.
Fig. 4, is a view in elevation, and Fig. 5, a plan view of the principal (upper)
part of the burner.
Figs. 6 & 7, show how the removable ring (for carrying ornaments only in this
case) may be also carried from the lower part of the burner.
Figs. 8 and 9, show in elevation and plan view how the ring may be carried
ineide the vertical rods.
Similar numbers refer to similar parts throughout the several views.
Hitberto much inconvenience has been experienced in carrying the screens of
lamps having downhanging stretchers or rods, and in providing the said stretchers
with adequate ornamentation. In most cases, where such screens are carried upon
the burner, it is necessary to carry same between (within) the rods, thus requiring
the rods to be very wide apart; this, in turn has necessitated a very large opening
in the top shade, which has obvious objections while the screen can, in such cases
be removed only by removing the chimney lying within and above the screen,
with the consequent risk of damaging mantle of burners. By this our invention
we are able to reduce the width of parallel rods to a minimum, in providing a
simple means of screening from the outside of the said bars, in such
a way as
to secure the ready removal or re-fixing of same without any interference with

page_text: chimney. Also attempts have been made to ornament the said parallel bars, by
means of scrolls &c. carried upon them, that is attached to them. We secure the
necessary crnamentation without in any way adding to, or interfering with the
rods or burners, by providing removable ornaments as hereinafter described.
We effect these improvements by our invention as follows:
Referring first for instance to what are known as downhanging lamps (as shown
in Fig. 1); as is well known the burner 10, is carried at the lower end of, and
between two rods 11. Such burners are usually made with three outstanding
spurs or projections 12, (see Figs. 1, 4 & 5) and also with a horizontal flange 13. The
burner is also usually made in two parts, the upper part (as shown in Figs. 4 & 5),
being made to removably slide and rest upon the shoulder at 24 of the lower part,
and is also revolvable thereon. We now provide the removable ring 14, (see
Figs. 1, 2 & 3) upon which is carried the screen 15. Upon the underside of this
ring 14, (see Figs. 2 & 3) are three (inverted) grooved projections 16, which cor-
respond with and rest upon the three spurs 12, so that the ring is carried thereon
as seen in Fig. 1. In order to preserve a fixed relative position of the ring with
the rods 11, the guides 17 are used to embrace them, so that having passed the
ring upwards from below the fitting, the burner (which is revolvable) is turned
around until its spurs are directly beneath the grooved projections 16, when the
ring may be lowered thereon. The said ring 14 may be carried from the flange 13,
or other similar part, by making the projection 16, or other similar projections,
sufficiently long to reach and rest upon the said flange. In such cases in order to
permit of the ring being passed upwards from below the burner, one at least of
such projections must be made springwise or leverwise, to move out of the way of
the flange in order to pass over it, but the method shown is much preferable.
It will now be readily seen that upon the ring 14, we may most conveniently
carry ornamental parts or scrolls such as 20, and particularly does this enable
us to ornament those parts which have hitherto received little or no ornamenta-
tion such as immediately about or below the burner, and such ornaments are thus
carried without any difficulty of fixing, or interference with the necessary atten-
tion to the burner or light, such as cleaning, lighting &c., and at the same time
leaving the rods 11, quite free.
It will now further be seen that the purpose of the guides 17, (see Figs. 2 & 3)
is to fix the relative position of the ornaments, in line with the rods 11, so that we
thereby avoid any increase of shadow from the flame.
A modified device for carrying the ring 14, with its ornaments 20, but without
rods 11, is shown in Figs. 6 & 7, in which the projections 16, may be made with
the open slots 25, instead of the inverted grooves before named, so that the
spurs 12 may rest in such slots to prevent rotation except with the burner; but
the weight is carried by means of the lower ring 14", which is supported upon
the shoulder 26, (or other suitable shoulder) of the burner. The two rings are
rigidly connected to each other by means of the ornamental scrolls 20, which thus
affords a firmer method of carrying the ornaments with increased artistic effect.
In this case it will be again noticed that the ornamental scrolls are in line with
the metal forming the spurs, so as to avoid increase of shadow as much as possible.
Thus again such ornaments are carried without interference with the burner. For
the accommodation of bye passes (when such are used) we provide the guide or
crutch 27, upon the ring 14°, so that it may span the bye pass and thus preserve
a definite relative position between the ornamental scrolls and the said bye pass.
In order to carry the ornaments 20, in cases where the ring 14, must lie within
the rods 11, (for any reason such for instance as when adapting this our inven-
tion to an existing lamp fitting) we provide the recesses 23, upon the outside of
the ring, as seen in Figs. 8 and 9, so that the scrolls 20, may be turned around
until they become central (in line) with the rods 11, (to avoid shadow as before
stated). Although we have shown our invention as applied to the well known
incandescent burner, still we do not limit ourselves thereto, as other burners may

page_text: be provided with suitable projections, equivalent to those herein marked 12, 13
or 26, upon which the ring 14 or 14" may be carried.
Having now particularly described and ascertained the nature of this our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
1. The ring 14, for carrying a screen or ornaments or both, arranged in combina-
tion with the burner and with or without suspending rods, substantially in the
manner described.
2. The combination with the lamp having rods 11, and burner 10, of the remov-
able ring 14, having grooved projections 16, and guides 17, for the purposes
specified substantially as described and shown in Figs. 1, 2, 3, 4 and 5.
3. The modified combination in which the ring 14, or 14ª, or both, is supported
substantially as shown in Figs. 6 and 7, the whole combination with burner, being
arranged substantially as described, and for the purposes specified.
4. The modified combination in which the ring 14, is adapted by outside
recesses 23, 23, to embrace rods 11, 11, substantially as shown in Figs. 8 and 9,
the whole combination with burner being arranged substantially as described.
