page_text: I EDWARD ALEXANDER RIPPINGILLE of the Aston Brook Lamp Works Aston-
juxta-Birmingham in the County of Warwick Lamp Manufacturer do hereby
declare the nature of this invention to be as follows:-
.
The invention relates to that class of suspension lamp in which the part
carrying the lamp is connected by chains, passing over fixed pulleys, to the
lantern or casing of the lamp so that the one part acts as a counterbalance to
the other.
According to my invention I connect to the part carrying the lamp two or more
vertical rods which work in guides fixed to the angles or other parts of the framing
of the lantern or casing and to the upper part of the latter I connect other rods or
a frame; to one set of these rods I connect one end of the supporting chains the
other ends of which are fixed to the other set of rods.
The upper ends of these rods are so shaped and combined as to give the
appearance of a frame or frames attached to the upper part of the lantern or
casing.
In some cases I connect to the rods or frame at the upper part of the lamp
carrier a vertical rod which slides through a guide formed in the rods or frame at
the upper part of the lantern one end of the chains being fixed to the upper end
of the vertical rod, the other. ends of such chains being connected with the rods
or frame at the upper part of the lantern. In other cases such vertical rod is
dispensed with and the chains are then connected directly to the top rods or frame
of the lamp carrier and pass through guides before described.
I also provide the lamp carrier or the lantern or casing with a bolt or catch
which may be operated in both directions by hand to lock the lamp carrier frame
in its lowered position during the removal and trimming of the lamp and to release
the same when the lamp is to re-ascend; or the said bolt or catch may be self
acting and the act of placing the lamp in position in its holder may be caused to
release the said bolt or catch.

I EDWARD ALEXANDER RIPPINGILLE of the Aston Brook Lamp Works, Aston-
juxta-Birmingham in the County of Warwick, Lamp Manufacturer 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:
The invention relates to that class of suspension lamp in which the part
carrying the lamp is connected by chains, passing. over fixed pulleys, to the
lantern or casing of the lamp, so that one part acts as a counterbalance to the
other.
According to my invention I connect to the part carrying the lamp two or more
vertical rods which work in guides fixed to the angles or other parts of the framing
of the lantern or casing and to the upper part of the latter I connect other rods or
a frame; to one set of these rods I connect one end of the supporting chains, the
'other ends of which are fixed to the other set of rods.
The upper ends of these rods are so shaped and combined as to give the
appearance when the lamp is in its norinal position of a frame or frames attached
to the upper part of the lantern or casing.
In some cases I connect to the rods or frame at the upper part of the lamp
carrier a vertical rod which slides through a guide formed in the rods or frame at
the upper part of the lantern one end of the chains being fixed to the upper end of
the vertical rod, the other ends of such chains being connected with the rods or
frame at the upper part of the lantern. In other cases such vertical rod is
dispensed with and the chains are then connected directly to the top rods or framé
of the lamp carrier and pass through the guide before described.
I also provide the lamp carrier or the lantern or casing with a bolt or catch
which may be operated in both directions by hand to lock the lamp carrier frame
in its lowered position during the removal. and trimming of the lamp and to release
the same when the lamp is to re-ascend; or the said bolt or catch may be self
acting and the act of placing the lamp in position in its holder may be caused to
release the said bolt or catch.

And in order that my said invention may be more clearly understood and
readily carried into effect, I will proceed aided by the accompanying drawings
'more fully to describe the same.
1.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a vertical section; Figure 2 is an exterior view of the upper parts
and Figure 3 is a plan of a hall or suspension lamp constructed according to my
invention Figures 1 and 2 are drawn at right angles to each other. Figures 4, 5
and 6 are corresponding views to the above showing a different form of lamp and
Figure 7 is a sectional elevation of parts showing a slight modification.
In all the Figures like parts are marked with similar letters of reference.

page_text: a is a moveable frame or support at the lower part of the lantern which carries
the lamp in a basket or other support a¹ which may be of the form shown or of
circular or other suitable form,
To the part a two (or it may be more) vertical rods a' are fixed which are
guided in suitable guides b¹ fixed to opposite angles or other parts of the framing
of the lantern or casing b.
To the upper part of the lantern or casing 6 I connect rods or a frame b³; the
upper parts of the rods a² are so shaped and combined as to give the appearance
when the lamp is in its normal position of a solid frame or frames attached to the
upper part of the lantern or casing b.
The rods or frames a² 69 according to the arrangement shown at Figures 1, 2, 3
are so combined and arranged as to give the appearance of a solid cross frame
attached to the upper part of the lantern or casing b but in the arrangement shown
at Figures 4, 5, 6 the rods 6' and the upper parts of the rods a' are so shaped and
arranged as to give the appearance of three frames arranged in parallel planes and
connected to the upper part of the lantern or casing.
The upper parts of the rods a' may however be differently arranged and
combined so long as they give the appearance of a frame or frames attached to
the upper part of the lantern or casing.
The rods b in Figures 1. 2. 3 are shown connected together by a ring or
socket through which the chains c pass when the lamp is being lowered out of
the lantern or casing 6 and the said chains are connected at one end to the upper
parts of the rods 62 and at their other ends to a ball or other shaped attachment a³
fixed to the rods a². Thus according to the arrangement shown at Figures 1, 2
and 3 when the lamp is within the lantern or casing b the ball or other shaped
attachment as of the rods a rests within the underside of the ring or socket b³ and
thus assists in steadying and combining the parts.
In the modification shown at Figure 7 a rod a' is attached at its lower end to
the ball or attachment a whilst the chains c are at one end attached to the upper
part of such rod a*.
The said rod a passes through the ring or socket 63 and assists in correctly
guiding the rods a' in their upward and downward motions, whilst the rod a* also
gives the lamp the appearance of a gas lamp.
I also in some cases provide the lamp carrier or the lantern or casing with a bolt
or catch d which may be operated in both directions by hand to lock the lamp
carrier a¹ in its lowered position during the trimming of the lamp and to release
the same when the lamp is to re-ascend.
In the arrangement shown at Figures 1, 2, 3 such catch d is attached to the
upper end of a tube d' surrounding one of the rods a³ and such tube d¹ has fixed
at or near its lower end a handle d' by which such tube d' may be turned in order
to cause the catch d to pass under the bottom of the lantern or casing 6 to lock the
lamp carrier in its lowered position; by turning the tube in the contrary
direction the catch d will be released from the bottom of the lantern or casing b
when the lamp will be capable of rising into position within the latter.
Other arrangements of bolts or catches may be employed for the above purpose
and if desired the said bolt or catch may be self acting and the act of placing the
lamp in position in its holder may be caused to release the said bolt or catch.
This latter arrangement is represented at Figures 8 and 9 in which instead of
operating the catch d by the hand acting upon a lever handle d' the axial tube d'
has fixed thereto a lever d³ connected to a rod d' which is suitably guided and is
acted upon by a spring d³ having a tendency to turn the catch d into its locking
position as shown by the dotted lines. Thus when the lamp is removed the
spring d causes the catch d to lock the lamp carrier in its lowered position but
on replacing the lamp the inclined sides of the font or reservoir will overcome the
pressure of the spring d³ and push the rod d' in its guides so as to withdraw the
catch d from its locking position after which the lamp can rise into the body of
the lantern or casing.

page_text: I would here remark that my invention is equally applicable to ball or suspension
lamps of other forms than those shown in the drawings.
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:-
1. In hall or suspension lamps of the character herein referred to, the peculiar
arrangement and combination of rods a b' fixed respectively to the lamp holder or
basket a and to the lantern or casing b and supported by chains c substantially as
herein shown and described and for the purpose stated.
2. The peculiar combination and arrangement of rods a' b and a with the lamp
holder or basket a, the lantern or casing b and chains c substantially as herein
shown and described, with respect to Figure 7, and for the purpose stated.
3. In suspension lamps in which the body or casing acts as a counterbalance to
the lamp, the employment of locking arrangements for holding the lamp carrier
down for the removal or replacement of the lamp substantially as herein shown and
described.
