and other like Lamps and Lanterns.
I JOHN GRUBB trading as Charles Joyner and Company of Icknield Square
Monument Road Birmingham in the County of Warwick Brassfounder and
Chandelier and Gas Fitting Manufacturer do hereby declare the nature of this
Invention to be as follows:-
The object of my invention is so to construct the parts of the metal frames of
hall lamps and lanterns and other like lamps and lanterns that the parts of the
frames can be packed in a small compass for transit and storage and when required
can be readily built up or connected together so as to form a lamp or lantern
frame of the required shape.
My improvements are applicable to lamp and lantern frames square in plan or
of other angular figure in plan.
I will describe my invention as applied to a square lamp or lantern frame.
I form the uprights of the frame of angle strips each strip having at each end
a longitudinal half screw soldered or otherwise fixed to it so that when the flat
faces of two of the longitudinal half screws are put together a complete screw is
formed on which a screw nut can be screwed for binding or fastening the two half
screws together and the strips to which they are affixed. Each of the angle strips
consists of a strip of sheet metal bent along its middle so that the two parts or
webs are inclined to one another at an angle of fortyfive degrees.
I make the top and bottom horizontal pieces of the frame situated between the
vertical parts or uprights of flat strips either plain pierced or ornamented with any
desired pattern.
The parts of which the lamp or lantern frame is to be built up thus consist
of a set of angle strips with longitudinal half screws at top and bottom and a set
of flat strips the said parts being capable of being packed into a small compass.
In building up the frame from the parts described a pair of angle strips is taken
and the inner webs of the said pair of strips and the half screws at top and bottom
are placed face to face and on the top and bottom screws thus formed screw nuts
are screwed so as to securely bind the angle strips together and form one of the

page_text: uprights of the frame. The inner faces of the angle strips are in contact and keep
the outer webs of the said strips at right angles to one another and thus preserve
the square figure of the lamp frame. The several uprights being made in this
way the horizontal strips to form the top and bottom of the frame are then
soldered or otherwise fastened between the uprights. The frame is completed and
glazed in the ordinary manner.
When lamp or lantern frames of a figure in plan other than square are to be
made the webs of the angle strips must be so inclined to one another that when
the inner webs are in contact they preserve the outer webs at the required angle.

I JOHN GRUBB trading as Charles Joyner and Company of Icknield Square

Chandelier and Gas Fitting Manufacturer 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:-
The object of my invention is so to construot the parts of the metal frames of

of other angular figure in plan.
I will describe my invention as applied to a square lamp or lantern frame.

strips
I make the top and bottom horizontal pieces of the frame situated between the
vertical parts or uprights of flat strips either plain pierced or ornamented with any
desired pattern.
Figure 1 of the accompanying Drawings represents in side elevation and Figure 2
in horizontal section, a hall lamp or lantern frame, square in plan, made according
to my invention; Figures 3 and 4 represent in side elevation one of the uprights
of the lamp or lantern frame, the screw nuts for binding the angle strips together
being omitted in Figure 4; Figure 5 represents a cross section of Figure 4 and
Figure 6 represents in side elevation partly in section and end elevation, the two
angle strips carrying the half screws separated from each other.
The same letters of reference indicate the same parts in the several Figures of
the drawings. Each of the uprights of which the lamp or lantern frame is com-
posed consists of two similar shaped angle strips marked respectively a, a the two
parts or webs of each strip a being inclined to one another at an angle of forty five
degrees as seen in Figures 2, 5 and 6. Each of the two strips a. forming the
upright has at each end a longitudinal half screw b soldered or otherwise fixed
to it. When the flat faces of the half screws b, b at the top and bottom of the
angle strips a, a are brought together they form complete screws at the top and
bottom of the upright and by screwing binding or fastening ornamental screw
nuts c, c upon the screws b, b the two angle strips are bound together and one
of the uprights of the lamp or lantern frame formed. By the binding together
of the two strips their inner webs are brought face to face and the outer webs are
situated and preserved at right angles to one another as represented in Figure 2.
The top and bottom pieces of the lamp or lantern frame consist of flat strips d, d
either plain pierced or ornamented in any desired manner. The top and bottom

page_text: strips d, d are furnished with ear pieces e, e by bending which over the edges of
the leaded or other panes of glass the glazing of the lamp frame is effected.
Although I prefer to make the strips a, a from sheet metal and to attach separately
formed half screws thereto by soldering or otherwise yet I do not limit myself to
this method of manufacture as the said strips may be made by casting in which
case half pins to be made into screws are cast on the ends of the strips.
In building up the frame from the parts described a pair of angle strips a, a
Figure 6 is taken and the inner webs of the said pair of strips and the half
screws b, b at top and bottom and placed face to face and on the top and bottom
screws thus formed screw nuts c, o are screwed so as to securely bind the angle
strips together and form one of the uprights of the frame. The inner faces of the
angle strips are thus in contact and keep the outer webs of the said strips at right
angles to one another and thereby preserve the square figure of the lamp frame as
shown in Figure 2. The several uprights being made in this way the horizontal
strips d, d to form the top and bottom of the frame are then soldered or other-
wise fastened between the uprights. The frame is completed and glazed in the
ordinary manner.
When lamp or lantern frames of a figure in plan other than square are to be
'made the webs of the angle strips must be so inclined to one another that when
the inner webs are in contact they preserve the outer webs at the required angle.
The parts of which the lamp or lantern frame is to be built up thus consist
of a set of angle strips with longitudinal half screws at top and bottom and a set
of flat strips, the said parts being capable of being packed into a small compass.
Instead of fastening together the angle strips described and represented or
similar angle strips from which the uprights of the lamp frame are made by half
screws and screw nuts the said angle strips may be fastened together in other
ways, but
have found the arrangement described and represented to answer well
in practice.
Having now particularly described and ascertained the nature of my inven-
tion and the manner of performing the same I declare that I claim as my invention
of "Improvements in the manufacture of hall lamps and lanterns and other like
lamps and lanterns "
First Making the frames of the said lamps and lanterns of a set of uprights
and a set of horizontal strips soldered or otherwise fixed between the said
uprights to form the top and bottom of the frames each upright of the frame
consisting of two angle strips and each strip having longitudinal half screws at
top and bottom the two strips being bound or fastened together to form an
upright by placing the flat faces of the half screws together and screwing upon
the complete screws thus formed ornamental or other screw nuts substantially
as herein before described and illustrated in the accompanying Drawings.
Secondly Inclining the webs of each angle strip at such an angle to one
another that when the inner webs of the two angle strips are in contact, the
outer webs are at right angles or other required angle to one another and thus
preserve the square or other figure of the lamp or lantern frame substantially as
herein before described and illustrated in the accompanying Drawings, whether the
angle strips be fastened together by longitudinal half screws and screw nuts or are
otherwise fastened together.
