IMPROVEMENTS IN THE CONSTRUCTION OF FRAMES FOR SUSPENSION LAMPS
Year: 1884

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 the said invention for IMPROVEMENTS IN THE CONSTRUCTION
OF FRAMES FOR SUSPENSION LAMPS to be as follows:-
Frames for suspension lamps as heretofore constructed except when cast in one
piece are comparatively costly in construction and are either made incapable of
being taken to pieces and consequently cumbersome for package or when inade
capable of disconnection of the parts, such disconnection has involved considerable
time and labour..
According to my present invention I construct such descriptions of frames in
parts capable of ready connection and disconnection with small expenditure of time
and labour and at the same time of simple and cheap construction.
For this purpose I employ three or more arins or branches which are shaped at
their lower ends to fit corresponding parts formed in or on a central piece or block
the centre of which is tapped to receive a screw which in combination with a disc,
plate or block, or with the bottom of the font basket is employed to fix the arms or
branches to the central piece or block.
These arms or branches when no basket is employed are so shaped as to be
capable of receiving and securely holding the. lamp font and they are also formed
with parts to support the lamp shade or, if desired, a ring to support the shade
may be placed in position on suitable seats or supports formed on the arms or
branches and such ring together with the arms or branches are preferably so
formed as to cause the same to afford mutual support to each other.
If desired instead of employing a single central screw for connecting the arms or
branches to the central piece or block, a separate screw may be used for each arm
or branch.

juxta Birmingham in the County of Warwick, Lamp Manufacturer do hereby
declare the nature of the said Invention for IMPROVEMENTS IN THE CONSTRUCTION
OF FRAMES FOR SUSPENSION LAMPS and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
Frames for suspension lamps as heretofore constructed, except when cast in one
piece are comparatively costly in construction and are either made incapable of
being taken to pieces and consequently cumbersome for package or when made
capable of disconnection of the parts, such disconnection has involved considerable

For this purpose I employ three or more arms or branches which are shaped at
their lower ends to fit corresponding parts formed in or on a central piece or block
the centre of which is tapped to receive a screw which in combination with a disc,
plate or block or with the bottom of the font basket is employed to fix the arms or
branches to the central piece or block.
These arms or branches when no basket is employed, are so shaped as to be
capable of receiving and securely holding the lamp font and they are also formed
with parts to support the lamp shade or if desired a ring to support the shade may
be placed in position on suitable seats or supports formed on the arms or branches
and such ring together with the arms or branches are preferably so formed as to
cause the same to afford mutual support to each other.
If desired instead of employing a single central screw for connecting the arms or
branches to the central piece or block a separate screw may be used for each arm
or branch.
'
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.
Figure 1 is an elevation of one of my improved frames for suspension lamps
showing a lamp and shade in position therein. Figures 2 and 3 are respectively a.
cross section and a plan of a central piece or block showing the lower end of one of
the arms or branches in position therein and Figure 4 is an elevation of parts of one
of the arms or branches showing the method of supporting the lamp and shade.
Figure 5 is an elevation of another of my improved frames for suspension lamps
showing the same provided with a ring to support the shade and with a basket for
holding the lamp. Figure 6 is a section of the basket showing the attachment of
the same to the central piece or block and Figure 7 is an elevation of part of one
of the arms or branches showing the method of carrying the ring for the shade.

page_text: Figure 8 is an elevation and Figure 9. is a plan of another of my improved
frames for suspension lamps, and Figure 10 is a separate view of parts of the
same,
In all the figures like parts are marked with similar letters of reference.
a a a are three arms or branches which at their lower ends a¹ are shaped to fit -
corresponding parts formed in, or it may be, on a central piece or block b. the
centre of which is tapped bored or otherwise formed with a hole to receive a
screw c which in combination with a nut c¹ and with a disc, plate or block das
shown in Figures 1, 2, 8 and 9 or in combination with the bottom of the front..
basket e as shown at Figures 5 and 6 is employed to fix the arms or branches a to
the central piece or block b. The arrangement represented in the drawings consists
of a screw bolt c, the head of which rests upon the upper surface of the disc, plate
or block d or upon the bottom of the font basket e, whilst the lower end is provided
with an ornamental nut c¹ by which the said parts a, b, and d or e are firmly
connected together but it is evident that the hole in the central piece or block b
may be formed with a screw thread to receive the screw c thereby dispensing with
the nut c¹ or if desired the screw c may in such case extend beyond the central
piece or block b in which case an ornamental nut c¹ could be screwed thereon and
act as a lock nut.
In the arrangement represented at Figures 1 to 4 the lamp font f is supported
directly on the seats a² of the arms or branches a and the shade g is supported
directly on the seats a³.
In the arrangement represented at Figures 8, 9 and 10 a ring h to support the
lamp font f is placed on the seats a², and such ring his held in position by
projections as on the arins or branches a or by other suitable means, whilst another
ring i to support the shade g is placed on the seats a³.
In the arrangement represented at Figures 5 to 7 the lamp font f is supported
in the basket e whilst the ring i in addition to being supported on the seats a³ is
so formed at its upper edge as to be firmly held by the hooks or clips at formed on
the arms or branches a which arins or branches are placed in position on the said
ring i by first placing the arms or branches a in the position shown in dotted lines
in Figures 7 after-which the said arms or branches are placed in the position
shown by the full lines. In this case the arms or branches & and the ring i afford
mutual support to each other and the lamp frame is thereby made strong and rigid.
Other methods of connecting the ring with the arms or branches a may be
employed.
I would here remark that the shapes of the various parts and fittings may be
varied without departing from the peculiar character of my Invention and if
desired instead of employing a single screw c for connecting the arms or branches a
to the central piece or block ba separate screw may be employed for each arm or
branch.
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. The combination of the arms or branches a with the central piece or block b
by means of one or more screws c and a disc, plate or block d substantially as
herein shown and described and for the purpose stated.
2. The employment of arms or branches a formed with seats or supports a², a³
and connected to a central piece or block b substantially as herein shown and
described and for the purpose stated.
3. The employment of arms or branches a formed with seats or supports a², a³
and with hooks or clips at in combination with a shade ring 2, central piece or
block b one or more screws c and disc or plate d substantially as herein shown aud
described and for the purpose stated.

page_text: 4. The combination of arms or branches a, seats or supports a³, hooks or clips a¹
shade ring i, font basket. e central piece or block b and one or more screws c
substantially as herein shown and described and for the purpose stated.
