Improvements in Pendants for Supporting Oil Lamps.
We, JOHN HARPER AND COMPANY, LIMITED, of Albion Works, Willenhall
in the County of Stafford, Ironfounders, and CHARLES RETALLACK, a Director
of the said Company, do hereby declare the nature of this invention to be as
follows:-
This invention relates to pendants for the purpose stated in the title, which are
each provided with a ring or cup for supporting the lamp and with a ring for
supporting the shade. In such pendants, as usually constructed, the former ring,
or cup, is either a sufficient distance below the latter ring to enable the lamp to
be removed from the pendant, for replenishing it with oil or for other purpose, and
to be replaced therein, by passing it between the lower ring or cup and the shade
ring, in which case the light is too low down to allow the shade to properly reflect
and diffuse the light; or if the lower ring, or cup, is not placed sufficiently below
the shade ring to allow of the lamp being passed through between them, the shade
has to be removed and the lamp lifted up through the shade ring to remove it
from the pendant, for replenishing with oil or for other purpose, and the lamp bas
to be lifted over and again passed through the shade ring to replace it within
the pendant, and this method of removing and replacing the lamp is very incon-
venient; more especially in the case of a very large sized lamp such as is
frequently now made.
The above inconveniences are obviated, according to this invention, by forming
the ring or cup which supports the lamp in two parts one of which may be opened
or moved out from the other to allow of the removal and replacement of the
lamp. When the ring or cup is open, the lamp reservoir may be put sideways into
the one portion thereof and the other portion be then closed up to enclose the
reservoir between itself and the portion within which it was first placed, and the two
portions of the ring or cup may then be securely fastened together to prevent
the one portion from being accidentally opened out from the other portion.
According to a convenient application of the invention, one portion of the ring
or cup which supports the lamp is fixed rigidly to the main portion of the pendant,
and the other portion of such ring or cup is hinged at one end or side to the fixed
portion so that it may be turned upon such hinge to open it out from the fixed
portion and to close it up thereagainst. The end or side of the hinged portion of
the ring or cup which is remote from the hinge may be formed with a lug having
a tongue projecting therefrom which as the hinged portion is closed in passes
through a slot formed to receive it in a lug formed with the corresponding end of
the fixed portion of the ring or cup, and the parts may be fastened together by
means of a hinged catch or hook, or a pin or the like, which is passed through
the outer end of the tongue which projects for the purpose beyond the lug last
described. The hinge may be formed by means of lugs projecting from the fixed
and movable parts of the ring or cup, respectively, through which the hinge pin is
passed. The arms of the pendant may be fixed to the lugs which project from
the fixed portion of the ring or cup.
Any convenient means for fastening the parts of the ring or cup together when
closed un may be employed

page_text: If the ring or cup is divided into halves, the lamp will rest in place, without
other support, upon the fixed half, while the hinged portion is closed up and
fastened but, to give greater security, the fixed portion of the ring or cup may
be made somewhat more than a semicircle, and the hinged portion correspondingly
less. If the fixed portion does not too greatly exceed a semicircle, the lamp may
be placed therein without raising it above, or appreciably above, the height it
assumes when resting upon the ring or cup, as the slight clearance which is usually
allowed between the exterior of the reservoir and the interior of the ring or cup
will allow of this being done; but if the fixed portion of the ring or cup too
greatly exceeds a semicircle to allow of this being done, the lamp may be raised
somewhat above its normal height to bring a portion of reduced diameter of the
reservoir opposite the opening between the ends or sides of the fixed portion of the
ring or cup, and may then be passed between such ends or sides and lowered onto
its bearing.

Improvements in Pendants for Supporting Oil Lamps.
We, JOHN HARPER AND COMPANY, LIMITED, of Albion Works, Willenhall in
the County of Stafford, Ironfounders, and CHARLES RETALLACK, a Director of
the said Company, 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:-
Pendants for the purpose stated in the title, are usually each provided with a
ring or cup for supporting the lamp and with a ring for supporting the shade. The
former ring, or cup, is either a sufficient distance below the latter ring to enable
the lamp to be removed from the pendant, for replenishing it with oil or for other
purpose, and to be replaced therein, by passing it between the lower ring or cup
and the shade ring, in which case the light is too low down to allow the shale to
properly reflect or diffuse the light; or if the lower ring, or cup, is not sufficiently
below the shade ring to allow of the lamp being passed through between them, the
shade has to be removed and the lamp lifted up through the shade ring to remove
it from the pendant, for replenishing with oil or for other purpose, and the lamp
has to be lifted over and again passed through the shade ring to replace it within
the pendant, and this method of removing and replacing the lamp is very incon-
venient, more especially in the case of a very large sized lamp such as is frequently
now made. Even, however, when the shade ring is sufficiently high up to enable
the lamp to be passed between itself and the ring or cup for supporting it, and
when no shade ring is used at all, the lump has to be lifted up clear above the
supporting ring or cup, to remove it therefrom or place it therein, which in itself
is inconvenient, more especially in the case of a large sized lump.
The above inenveniences are obviated, according to this invention, by forming
the ring or cup which supports the lamp in two parts one of which may be opened
or moved out from the other to allow of the removal and replacement of the lamp.
When the ring or cup is open, the lamp reservoir may be put sideways into the
one portion thereof, and the other portion be then closed up to enclose the
reservoir between itself and the portion within which it was first placed, and the
two portions of the ring or cup may then be securely fastened together to prevent
the oue portion from being accidentally opened out from the other portion.

page_text: According to a convenient application of the invention, one portion of the ring
or cup which supports the lamp is fixed rigidly to the main portion of the pendant,
and the other portion of such ring or cup is hinged at one end or side of the fixed
portion so that it may be turned upon such hinge to open it out from the fixed
portion and to close it up thereagainst. This application of the invention, in the
case of a ring for supporting a lamp, is illustrated, by way of example, by the
drawings herewith.
Figure 1 shews a plan of the ring for supporting the lamp. The hinged portion
is shewn by full lines as opened out, and by broken lines as closed in.
Figure 2 is an elevation of the lower portion of the pendant, showing both a
ring for supporting the shade aud the ring for supporting the lamp, except that the
hinged portion of the latter ring is removed and the remaining portion thereof is
seen as looking towards its inner face.
Figure 3 is a section through the ring for supporting the lamp, when the same
is closed, the section being taken transversely to a line passing through the joints
of the ring; and
Figure 4 is an elevation of the outer side of the end of the fixed portion of such
ring which is remote from the hinge, and shews the catch, hereinafter described,
to be in position fastening the outer end of the hinged portion of the ring to the
fixed portion.
The ring A for supporting the lamp is formed in two parts a and b, of which
the part u is fixed to the arms c of the pendant, conveniently by means of screws
which pass through lugs e el projecting from the opposite sides of the part a of the
ring, that is to say, in the manner in which the lamp rings are commonly or
frequently supported by the pendant arms. The shade ring B, which is of the
usual or any convenient character, is supported by the pendant arms in the usual
or any convenient manner. The inner end of the portion 6 of the lamp ring is
formed with a lug or heel f, by means of which it is hinged at g to the lug e of
the part a.
The outer end of the part 6 of the ring is formed with an outward
lug, from the face of which projects a tongue i. A slot is formed through the
Jug e of the part a through which the tongue i passes as the part is closed up
against the part a. A catch k is pivoted to the lug e on the opposite side to that
against which the lug comes, and is formed with a portion at one side of the
fulcrum which may engage, as shewn by Figure 4, with the tongue when the
sanie is passed through the slut j, by passing through a hole formed through
the tongue, and thus fasten the part of the ring in its closed position; and such
catch is formed also with a part at the other side of the fulcrum which may be
depressed by the thunib to raise the other end out of engagement with the
tongue.
The upper portion of the part a of the ring, namely, the part upon which the
lamp is first rested in putting it into place in the pendant, is preferably formed, as
shewn, to somewhat exceed a semi-circle, to ensure that the lamp will rest securely
thereupon while the hinged portion of the ring is closed up. This formation of
the part a of the ring is conveniently effected by carrying forward the upper
portion of such part at each end beyond the lower portion, thus forming extensions m.
Corresponding recesses or shouldered-down parts n are formed in the ends of the
upper portions of the part b of the ring, into which the extensions m fit when the
part is closed up against the part a, and thus when the ring is closed it presents
a continuous upper surface to receive the lamp. A ledge p is formed to project
from the lower side of the face of the lug e against which the lug h comes, in
order to support such lug, and consequently the outer end of the part 6 of the
ring, when such part is closed up. A corresponding projection of the lug e
serves as a support to the inner end of the part 6 of the ring when closed up.
If the fixed portion of the ring or cup does not too greatly exceed a semi-circle,
the lamp may be placed therein without raising it above or appreciably above, the
height it assumes when resting thereon, as the slight clearance which is usually
allowed between the exterior of the reservoir and the interior of the ring or cup

page_text: will allow of this being done; but, if the fixed portion of the ring or cup too
greatly exceeds a semi-circle to allow of this being done, the lamp may be raised
somewhat above its normal height to bring a portion of reduced diameter of the
reservoir opposite the opening between the ends or sides of the fixed portion of the
ring or cup, and may then be passed between such ends or sides and lowered on to
its bearing.
Having now particularly described and ascertained the nature of our said
invention, and in what manuer the same is to be performed, we declare that what
we claim is
1. A pendant for supporting an oil lamp, having the ring or cup which carries
the lamp formed with a portion which is fixed to the main portion of the pendant
and with a portion which may be readily opened out to enable the lamp to be
passed into the fixed portion, and which may be readily closed up again and
fastened in its closed position, substantially as described.
2. A pendant for supporting an oil lamp, having the ring or cup which carries
the lamp formed with a portion which is fixed to the main portion of the pendant,
and with a hinged portion which may be opened out to enable the lamp to be
passed into the fixed portion and may then be closed up to complete the ring or
cup, and be fastened in its closed position, substantially as described.
3. A pendant for supporting an oil lamp, provided with an opening lamp-ring or
cup, substantially as described and shewn (by way of example, in the case of a
ring) by the drawings herewith.
