County of Warwick Lamp Manufacturer and WILLIAM CROOK of No. 42 Erasmus
Road Birmingham aforesaid Manager of Works do hereby declare the nature of
this Invention to be as follows:-
In ordinary spring candle lamps the globe or shade holder constitutes a
permanent part of the tubular pillar of the lamp containing the candle and coiled
spring the candle being placed in the said pillar by the removal of the nozzle.
Our invention consists in making the globe or shade holders of spring candle
lamps separable from the top of the tubular pillar the said separable globe or shade
holder being capable of ready connection to and disconnection from the said pillar..
By making the globe or shade holder detachable from the pillar the introduction
of the candle into the pillar is greatly facilitated and globe or shade holders of
different kinds according to the character of the light required can be readily
adapted to the same lamp.
The globe or shade holder and the candle nozzle are combined together and form
one article. We prefer to connect the combined globe or shade holder and nozzle.

fastening the combined globe or shade holder and nozzle to the pillar of the
lamp. When we use a bayonet joint fastening we make the angle slots at
opposite sides of the top of the pillar and the studs for taking into the said
slots inside the base of the combined globe or shade holder and nozzle. By means
of an ornamental knob on the globe or shade holder and a stud on the top of the
pillar the position of the two parts of the fastening is indicated. When the
indicating knob and stud are coincident the two parts of the lamp are unfastened
and can be separated. When the indicating stud is turned from under the knob
the two parts of the lamp are fastened together.
When instead of a metallic pillar a glass or other non-metallic pillar is used the
non-metallic pillar is furnished at top with a metallic mount or ring provided with
the angle slots of the fastening.

We ROWLAND FRANCIS HEATH of No. 117 Leopold Street Birmingham in the
County of Warwick, Lamp Manufacturer and WILLIAM CROOK of No. 42 Erasmus
Road, Birmingham aforesaid, Manager of Works, do hereby declare the nature of
our invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-—
In ordinary spring candle lamps the globe or shade holder constitutes a
permanent part of the tubular pillar of the lamp containing the candle and coiled
spring, the candle being placed in the said pillar by the removal of the nozzle.
Our invention consists in making the globe or shade holders of spring candle
lamps separable from the top of the tubular pillar the said separable globe or shade.
holder being capable of ready connection to and disconnection from the said pillar..
By making the globe or shade holder detachable from the pillar the introduction
of the candle into the pillar is greatly facilitated and globe or shade holders of
different kinds according to the character of the light required can be readily
adapted to the same lamp.
The globe or shade holder and the candle nozzle are combined together and
form one article. We prefer to connect the combined globe or shade holder and
nozzle to the top of the pillar by means of a fastening resembling a bayonet joint
fastening but we do not limit ourselves to any particular arrangement for fastening
the combined globe or shade holder and nozzle to the pillar of the lamp.
When we use a bayonet joint fastening we make the angle slots at opposite
sides of the top of the pillar and the studs for taking into the said slots inside
the base of the combined globe or shade holder and nozzle. By means of an
ornamental knob on the globe or shade holder and a stud on the top of the
pillar the position of the two parts of the fastening is indicated. When the
indicating knob and stud are coincident the two parts of the lamp are unfastened.

the two parts of the lamp are fastened together.
When instead of a metallic pillar a glass or other non-metallic pillar is used the
non-metallic pillar is furnished at top with a metallic mount or ring provided with
the angle slots of the fastening.
Should it be desired to use with the candle lamp a reading shade with an open
gallery in place of the globe or shade holder, the latter is removed from the top
of the lamp pillar and is replaced by the reading shade. In this way shades of
various kinds may be used with the same lamp.
Figure 1 of the accompanying drawings represents in elevation a metallic spring
candle lamp in which the globe or shade holder is made detachable from the
tubular pillar of the lamp according to our invention and Figure 2 represents the
detachable globe or shade holder separated from the lamp pillar; Figure 3
represents in elevation and Figure 4 partly in elevation and partly in section, the
candle lamp provided with a reading shade in place of the globe or shade holder
represented in Figures 1 and 2; Figure 5 represents the reading shade holder and
the nozzle detached from the lamp.
The same letters of reference indicate the same parts in the several Figures of
the drawings.
a is the tubular pillar of the lamp containing the candle 6 and spring c;
d is the ordinary globe or shade holder and e is the glass shade carried by it; f is
the reading shade holder and g the shade carried by it. The globe or shade
holder d or reading shade holder fis connected to or combined with the candle
nozzle h and form one article. The combined nozzle h and shade holder d or fis
connected to the top of the pillar a either by screwing or by a bayonet joint or
other fastening.
In Figures 1. 2. 3. 4 and 5 the combined nozzle and shade holder is connected to
the pillar a by screwing. For this purpose the bottom of the nozzle h is furnished
with a concave screw at i (see Figure 2) and the top of the pillar a with a convex
screw for the concave screw at i to screw upon. In order to place a candle in the
pillar a the combined nozzle and shade holder is unscrewed from the top of the
pillar a and after the introduction of the candle is again screwed in its place.
When a reading shade holder or a shade holder of a different kind from that
marked d is required to be used with the candle lamp, the combined nozzle and
shade holder h and d is unscrewed from the lamp pillar a and the combined nozzle
and shade holder h and f, Figure 5, is screwed upon the lamp pillar as represented
in Figures 3 and 4. In this way, shade holders of different kinds according to
the character of the light required can be readily adapted to the same lamp.
.
Figure 6 represents partly in elevation and partly in section, a spring candle
lamp in which a glass or other non-metallic pillar is used. In this case a
metallic candle tube k is used within the non-metallic pillar the said candle
tube k carrying at its top a metallic mount m which is cemented or otherwise fixed
to the top of the non-metallic pillar l. In the arrangement Figure 6 the combined
nozzle and shade holder h, d is connected to the mount m by a bayonet joint
fastening; Figure 7 represents the shade holder and nozzle together with the
mount m detached from the pillar 1 and Figure 8 represents the metallic mount in
perspective.
The mount m has slots n, n in it at opposite sides and the inside of the bottom
of the nozzle h is furnished with pins or studs for taking into the said slots n, n;
p is a knob on the gallery or shade holder d and q is a stud on the mount m for
indicating the position of the two parts of the fastening. When the knob p is
turned from over the indicating stud as represented in Figure 6 the combined
nozzle and shade holder is fastened to the mount m and when the indicating
knob p and stud q are coincident the two parts are unfastened and can be
separated.
The reading shade holder Figures 3. 4 and 5 to be applied to the pillar of
the candle lamp in place of the ordinary shade holder Figures 1 and 2 need not be

combined with a nozzle. In this case the ring r to which the arms of the reading
shade holder fare attached is after the removal of the shade e from the holder d
slipped upon the nozzle h of the said holder d. The trouble of disconnecting the
shade holder d from the pillar of the lamp is thus avoided.
By globe or, shade holders we mean the holder by which any globe, shade,
chimney or reflector is supported around the flame of a candle.
Having now particularly described and ascertained the nature of our invention
and the manner in which the same is to be performed we 'declare that what we
claim is;-
First Making the globe or shade bolders of spring candle lamps separate from
the pillars of the said lamps and combining the said globe or shade holders with
the nozzles of the said lamps, the combined shade holders and nozzles being capable
of ready connection to and disconnection from the pillars of the lamps whereby
globe or shade holders of different kinds can be adapted to the same candle lamp.
substantially as herein before described and illustrated in the accompanying
Drawings.
Secondly-The use with combined globe or shade holders and nozzles of the
kind represented in Figures 1 and 2 of a reading shade holder of the kind
répresented in Figures 3. 4 and 5 or other kinds of shade holders but without a
nozzle for the purpose and substantially as herein before described.
