I CHARLES WALKER TORR of the Firm of Robert Walter Winfield and Company
of Cambridge Street Works Birmingham in the County of Warwick Merchants and
Manufacturers do hereby declare the nature of this Invention to be as follows :-
My invention consists of the improvements hereinafter described in constructing
the bodies of hall lamps and other like suspended lamps.
Instead of making the bodies of the said lamps of rigid glazed frames for enclosing
the burners of the lamps as usual I make the said body of a series of pierced or
perforated plates of thin sheet metal the said plates being so jointed together that by
giving a sliding motion to their lower parts as herein after described they can be
brought nearly parallel to one another so as to collapse the body. When the body of
the lamp is in the collapsed position described the burner is uncovered. The collapsed
lamp body occupies less room for carriage or transit and storage than lamps having
rigid frames or bodies of the ordinary kind. I will describe my invention as applied
to the body of a hall lamp having a figure somewhat resembling two six sided pyramids
placed base to base but I do not limit myself to any particular figure of the body of
the lamp.
To the two nearly parallel down pipes of the burner I fix a ring having a hexagonal
figure externally. This ring constitutes the top of the body. Around the said ring
I joint a series of six perforated plates having a taper figure the narrow end of each
plate being jointed to the ring. I take a second series of six perforated plates
similar in size and shape to those already described and I joint the broad ends of the
top series to the broad ends of the second series and I also joint the narrow or
bottom ends of the bottom series of plates to a ring similar in size and shape to the
top ring fixed to the burner pipes. The bottom ring is not fixed to the burner pipes
but is loose and is capable of sliding up and down upon the said burner pipes. A lamp
body consisting of a fixed top ring and a loose bottom ring and two sets of perforated
plates jointed together and to the two rings is thus formed. On the burner pipes and
below the burner are cross stops or supports on which the bottom ring of the
collapsible lamp body rests when it is in its lowered or normal position. By pressing
upwards the lower sliding ring of the body the two sets of perforated plates can be

engaged with the slots their ends are opened out or expanded. The several parts are

knuckle joints may be used. Although I generally make the body of the lamp
collapsible as described yet the perforated plates may be so joined together as to be
incapable of folding and thereby form a rigid body and some of the perforated metal
plates may be covered inside with glass or the perforated plates constituting the upper
half of the body may be replaced by glazed frames.
My invention is applicable to lamps burning oil or other liquid or solid combustibles
as well as to gas lamps and electric lamps.

COMPLETE SPECIFICATION.
Improvements in Hall Lamps and other like Suspended Lamps.
I CHARLES WALKER TORR of the firm of Robert Walter Winfield and Company
of Cambridge Street Works, Birmingham in the County of Warwick, Merchants and
Manufacturers, do hereby declare the nature of my Invention and in what manner
the same is to be performed to be particularly described and ascertained in and by
the following statement :-
My invention consists of the improvements hereinafter described in constructing
the bodies of hall lamps and other like suspended lamps.
Instead of making the bodies of the said lamps of rigid glazed frames for enclosing
the burners of the lamps as usual, I make the said body of a series of pierced or
perforated plates of thin sheet metal the said plates being so jointed together that by
giving a sliding motion to their lower parts as hereinafter described they can be
brought nearly parallel to one another so as to collapse the body. When the body of
the lamp is in the collapsed position described the burner is uncovered. The collapsed

page_text: lamp body occupies less room for carriage or transit and storage than lamps having
rigid frames or bodies of the ordinary kind.
I will describe my invention as applied to the body of a hall lamp having a figure
somewhat resembling two six sided pyramids placed base to base but I do not limit
myself to any particular figure of the body of the lamp.
To the two nearly parallel down pipes of the burner I fix a ring having a hexagonal
figure externally. This ring constitutes the top of the body. Around the said ring
I joint a series of six perforated plates having a taper figure the narrow end of each
plate being jointed to the ring. I take a second series of six perforated plates similar
in size and shape to those already described and I joint the broad ends of the top
series to the broad ends of the second series and I also joint the narrow or bottom
ends of the bottom series of plates to a ring similar in size and shape to the top ring
fixed to the burner pipes. The bottom ring is not fixed to the burner pipes but is loose
and is capable of sliding up and down upon the said burner pipes. A lamp body
consisting of a fixed top ring and a loose bottom ring and two sets of perforated
plates jointed together and to the two rings is thus formed. On the burner pipes
and below the burner are cross stops or supports on which the bottom ring of the
collapsible lamp body rests when it is in its lowered or normal position. By pressing
upwards the lower sliding ring of the body the two sets of perforated plates can be
brought nearly parallel to one another so as to uncover the burner, the collapsed
or nearly flattened body being held in that position by the wedging of the sliding
ring upon the slightly inclined burner pipes. By a slight downward pressure on
the sliding ring the collapsed body is liberated and descends taking its expanded
position the sliding ring falling to and being supported upon the fixed stops or
supports on the burner pipes.
The broad ends of the two sets of perforated plates may be jointed together
and their narrow ends jointed to the top and bottom rings by T pieces on one
part taking into slots in the other part the ends of the T pieces being folded
inwards to permit them to pass through the slots. After the T pieces have been
engaged with the slots their ends are opened out or expanded. The several parts
are in this way jointed together. I do not however limit myself to this kind of
joint as knuckle joints may be used.
Figures 1 and 2 of the accompanying Drawing represent side elevations of a
collapsible hall lamp or other like lamp constructed according to my invention
the body of the said lamp having the figure of two six sided pyramids placed base
to base; Figure represents in perspective the upper part of the lamp body and
Figure 4 represents two of the pierced or perforated metal plates of the body
detached.
The same letters of reference indicate the same parts in the several Figures of the
drawing.
a is a hexagonal ring fixed to the nearly parallel burner pipes b, by the angle
pieces c, c (see Figure 3). Around this ring six perforated tapering metallic
plates d, d, d are jointed at their narrow ends and to the broad ends of the said
plates d, d, d the broad ends of another set of perforated plates e, e, e are jointed.
The narrow or bottom ends of the lower set of plates e, e, are jointed to a ring f
having the same shape as the top ring a. The bottom ring f is loose and is capable
of sliding up and down the burner pipes b, b. The jointing of the upper and lower
series of plates d, d, d and e, e, e to one another and to the top and bottom rings a
and is effected preferably by the T pieces g on one part taking into slots h in the
other part. The ends of the T pieces g are folded inwards to permit the said T pieces
to pass through the slots and after they have passed through the slots the said ends
are opened out or expanded as seen in the drawing. The several parts are in this
way jointed together. Knuckle joints or other kinds of joints may be employed
instead of the pieces and slots represented.
A lamp body thus constructed is capable of taking the expanded form represented
in Figure 1 for use or the collapsed form represented in Figure 2 for uncovering the
burner or for transit or other purpose.

page_text: When the lamp body is in its expanded state Figure 1 its lower edge or ring fis
supported upon the stops i, i carried by the burner pipes. In order to collapse the
lamp body it is only necessary to press upwards the lower sliding ring when the
two sets e, e, e and d, d, d of perforated plates are brought nearly parallel to one
another in the manner shown in Figure 2. The burner of the lamp is thereby
uncovered the collapsed or nearly flattened body of the lamp being held in that
position by the wedging of the sliding ring f upon the slightly inclined burner
pipes b. By a slight downward pressure on the sliding ring the collapsed body
of the lamp is liberated and descends taking the expanded position Figure 1, the
sliding ring falling to and resting upon the fixed stops i, i on the burner pipes b, b.
I do not limit myself as before stated to the figure represented of the collapsible
body of the lamp as other figures may be given to the said body; for example, it may
be square, hexagonal, octagonal or of other polygonal figure in cross section and the
sides may be inclined or parallel.
Although I generally make the body of the lamp collapsible as described and
represented yet the perforated metallic plates d, d, d and e, e, e may be so joined
together as to be incapable of folding and thereby form a rigid body and some of the
perforated metallic plates may be covered inside with glass or the perforated plates
constituting the upper or lower half of the body may be replaced by glazed frames.
When a rigid body composed of perforated plates is used both the top and bottom
rings are fixed to the burner pipes.
In some cases I prefer to give the rigid body of the lamp a spherical or globular
figure. In this case instead of making the body of perforated plates it is made of
two perforated metallic hemispheres rigidly connected together at their wide ends or
edges. Portions of the hemispheres are cut away in planes perpendicular to the axis
of the hemisphere.
The hemi-spherical perforated parts of the body of the lamp may be connected to
the burner pipes by rings fixed on the said burner pipes. The perforated hemispheres
may be made in parts and connected together.
My invention is applicable to lamps burning oil or other liquid or solid combustibles
as well as to gas lamps and electric lamps.
Having now particularly described and ascertained the nature of my invention and
the manner in which the same is to be performed I declare that I claim as my
invention of "Improvements in hall lamps and other like suspended lamps" ;—
First Constructing the bodies of the said lamps of two series of pierced or
perforated metallic plates jointed together and to a fixed ring and a sliding ring on
the burner pipes so as to make the said body capable of collapsing; or rigidly
connecting the pierced or perforated plates together so as to form a rigid body
substantially as herein before described and illustrated in the accompanying Drawing,
Secondly Making the rigid body of the lamp of pierced or perforated hemi
spherical metallic parts joined together edge to edge so as to give the said body a
spherical or globular form as herein before described.
Thirdly Making the collapsible or rigid body of the lamp partly of perforated
metallic plates and partly of glazed frames as herein before described.
