GEORGE ATKINS of the Firm of Atkins Brothers of Birmingham in the
County of Warwick Lamp and Chandelier Manufacturers. " IMPROVEMENTS IN
SHADE HOLDERS FOR GAS AND OTHER LAMPS."
My Invention consists first of the following improvement in connecting the
radial arms of the shade holders of gas and other lamps to the screw collars or
central screw bosses of the said holders. The said radial arms are ordinarily
connected to the screw collar or central screwed boss by soldering. According to
this part of my Invention, I make at the inner end of each of the radial arms, two
studs or projections and an abutting shoulder or stop, the said studs and stop
somewhat resembling the steps of a key, and I make across the screw collar or
central screwed boss, at the part where the arm is to be connected to it, a hole and
slot and also a seat of a size and having a position proper to receive the said studs
and the abutting shoulder or stop. The said studs and shoulder or stop are
stamped or otherwise fashioned from the end of the arm. When the studs on the
arm are introduced into the hole and slot in the screw collar and the shoulder or
stop made to seat itself upon its seat in the said collar, the ends of the studs
project slightly beyond the under face of the screw collar. By expanding or
rivetting the said projecting ends of the studs upon the under face of the screw
collar, the arm is securely connected to the said collar. In this way the several
radial arms of the shade holder are connected with the screw collar or central
screwed boss. By my Invention, the junction of the arms with the screw collar is
stronger than when they are connected by soldering in the ordinary way and the
liability to fracture of the said arms at their junction with the screw collar is
avoided.
My Invention consists secondly of the following improvements in securely
fastening the shades of gas and other lamps in their holders.

page_text: The outer ends of the radial arms of the shade holder are provided with seats or
recesses of the ordinary kind for receiving the lower edge of the shade. In order
to fix the shade securely in its seats in the radial arms, I apply to one of the said
arms a lever catch. This lever catch is jointed to the arm near the seat of the same
and has motion in a vertical plane. The upper or fastening arm of the said catch
is so arranged on the radial arm of the holder that when the shade is placed on
the said holder the said upper arm of the catch is situated within the shade. The
lower arm of the lever catch depends below the radial arm of the holder and is
formed into a handle for moving the said catch. The head of the lever catch is
curved or has a figure suitable for bearing against the concave lower edge of the
shade. After the shade has been placed in its seats on the radial arms, the handle
end of the lever catch is pressed inwards or towards the centre of the holder. The
upper arm of the lever catch is thereby moved outwards and its head made to
bear against the concave lower edge of the shade and thereby fasten the said shade
securely in the holder. A spring may be used to press the lever catch into its
fastening position.
Although generally a single lever catch is only required yet where a large shade
is used more than one lever catch. may be employed. Instead of fastening the
shade in its holder by a lover catch as described, a spring slide may be used for
that purpose. The said spring slide consists of a loop sliding on the radial arm of
the holder and pressed outwards by a coiled spring situated in an opening in the
said radial arm.
The upper edge of the slide carries a curved lip or projection of a
shape proper to bear against the lower concave edge of the shade. In order to
place the shade in the holder the fastening slide is pressed back and the edge of
the shade seated in the holder. The slide being released it is pressed outwards by
its coiled spring and the lip or projection of the said slide made to bear against the
lower concave edge of the shade and prevent it being lifted from its holder.

"
GEORGE ATKINS of the Firm of Atkins Brothers of Birmingham in the
County of Warwick Lamp and Chandelier Manufacturers. IMPROVEMENTS IN
SHADE HOLDERS FOR GAS AND OTHER LAMPS."
My Invention consists first of the following improvements in connecting the
radial arms of the shade holders of gas and other lamps to the screw collars or
central screwed bosses of the said holders. The said radial arms are ordinarily
connected to the screw collars or central screwed boss by soldering.
According to this part of my Invention, I make at the inner end of each of the
radial arms, one or more studs or projections and an abutting shoulder or stop, the
said studs and stop somewhat resembling the steps of a key and I make across
the screw collar or central screwed boss at the part where the arm is to be con-
nected to it a hole or holes and slot and also a seat of a size and having a position
proper to receive the said studs and the abutting shoulder or stop. The said studs
and shoulder or stop are stamped or otherwise fashioned from the end of the arm.
When the studs on the arm are introduced into the holes and slot in the screw
collar and the shoulder or stop is made to seat itself upon the seat in the said
collar the ends of the studs project slightly beyond the undorsurface of the screw
collar. By expanding or rivetting the said projecting ends of the studs upon the
undersurface of the screw collar the arm is securely connected to the said collar.
Or a single stud may be used and the fixing be effected by soldering the end of the
arm in the slot and rivetting the single stud on the underside of the screw collar.
In this way the several radial arms of the shade holder are connected with the
screw collar or central screwed boss.
By my Invention the junction of the arms with the screw collar is stronger than
when they are connected by soldering in the ordinary way and the liability to
fracture of the said arms at their junction with the screw collar is avoided
My Invention consists secondly of the following improvements in securely
fastening the shades of gas and other lamps in their holders.
The outer ends of the radial arms of the shade holder are provided with seats or
rocesses of the ordinary kind for receiving the lower edge of the shade.
In order to fix the shade securely in its seats on the radial arms, I apply to one
of the said arms a lever catch. This lever catch is jointed to the arm near the seat
of the same and has motion in a vertical plane. The upper or fastening arm of the
said catch is so arranged on the radial arm of the holder that when the shade is
placed on the said holder the said upper arm of the catch is situated within the
catch. The lower arm of the lever catch depends below the radial arm of the
holder and is formed into a handle for moving the said catch. The head of the
lever catch is curved or has a figure suitable for bearing against the concave lower
edge of the shade. After the shade has been placed in its seats on the radial arms,
the handle end of the lever catch is pressed inwards or towards the centre of the
holder. The upper arm of the lever catch is thereby moved outwards and its head
made to bear against the concave lower edge of the shade and thereby fasten the
said shade securely in the holder. A spring may be used to press the lever catch
into its fastening position.
Although generally a single lever catch is only required yet where a large shade
is used more than one lever catch may be employed.

page_text: I will now proceed to describe with reference to the accompanying Drawing the
manner in which my Invention may be performed.
Figures 1 and 2 represent elevations of a shade holder constructed according to
my Invention, holding a shade the said shade being represented partly in elevation
and partly in section. The lever catch of the shade holder is represented in action
in Figure 1 and out of action in Figure 2; Figure 3 is a plan of the holder
without the shade. The other Figures represent parts of the holder as herein after
explained.
The same letters of reference indicate the same parts in the several Figures of
the Drawing.
с
a, a, a are the three radial arms of the holder connected to the screw collar or
central screw boss b. One of the arms of the holder is represented in combination
with the boss b in Figure 4 and separately in Figure 5; Figure 6 represents the
screw collar or boss in section and plan separately. The inner or connecting end of
each radial arm is shaped of a figure resembling the steps of a key; that is, the
stepped end is provided with a shoulder or stop c and also with a pin d. Across
the collar or boss b equi-distant slots e, e, e are made and in the flange of the said
collar or boss, equi-distant holes f, f, f are made. When the stud d of the arm a
is introduced into the hole and the shoulder c into the slot e, the shoulder seats
itself on the seat at the bottom of the slot and the stud d projects slightly from
the under-face of the collar b. The stepped part of the arm near the pin d also
embraces the flange of the collar. After the end of the arm a has been thus fitted
upon the collar, the pin d is rivetted or expanded upon the under-face of the
said collar and the stepped end of the arm is soldered in its place. Or the arm a
may be connected to the collar or boss without the use of solder. In this case
I make at the stepped end of the arm, two studs d d and I make two holes in
the collar or boss where the arm is to be connected, in addition to the slot e, as
represented in section in Figure 7. By rivetting the two pins d, d, on the under-
side of the collar or boss 6 the arm of the holder is securely fixed to the central
collar or boss.
The lever catch for fastening the shade g upon the holder is marked h, i the said
catch being jointed at 2 to one of the radial arms a of the holder. When the shade
g is placed on the seats at k, k, k near the outer ends of the arms a, a, a of the
holder, the upper part of the lever catch is situated within the shade. The lower
or handle end i of the catch depends below the radial arm a to which the catch is
jointed as represented. The lever catch h, i is represented detached in Figure 8.
The head of the lever catch has a curved figure suitable for bearing against the
lower concave part of the inside of the shade. The lever catch h, i is fixed in its
fastening position by the jointed loop on the shade holder arm engaging with the
handle end of the said catch. This loop is shown separately in Figure 9. The
lever catch occupies the position represented in Figure 2 before the shade is placed
on the holder. After the lower edge of the shade has been placed upon the seats
at k, k, k on the radial arms a, a, a of the holder, the handle end i of the catch is
pressed inwards or towards the centre of the holder as represented in Figure 1. The
upper arm h of the lever catch is thereby moved outwards and its head is made to
bear against the lower edge of the shade and thereby prevent the latter being
removed from the holder. The lever catch is fixed in its fastening position by
engaging the jointed catch with the handle end of the said catch as represented
in Figure 1.
In order to unfasten the shade it is necessary to turn the loop from off the
handle end of the catch when the latter may be moved into the position repre-
sented in Figure 2. The upper arm of the catch no longer bearing on the shade
the said shade may be lifted from the holder. A spring may be used to press the
lever catch into the fastening position represented in Figure 1.
Instead of making the bearing edge of the head of the catch of metal the said
bearing edge may be made of india rubber, leather or other soft material.
In this case, I make the lever catch of the forked form represented in Figure 10

page_text: and enclose between its circular upper ends, a disc of india rubber or leather m
which takes a bearing against the shade instead of the metal edge of the catch first
described.
Two or more of the lever catches described and represented may be combined in
the same holder but for ordinary purposes only one of the said lever catches is
necessary.
Having now described the nature of my Invention and the manner in which the
same is to be performed I wish it to be understood that I claim as my Invention of
Improvements in Shade Holders for Gas and other Lamps :"-
First. Connecting the radial arms of the said shade holders to the serew collar or
central serow boss in the manner-herein before-described and illustrated in the
accompanying Drawing; that is to say, making the inner ends of the radial arms of
the holder of a stopped figure or of a figure somewhat resembling the steps of a key
and making in the screw collar or boss at the parts where the arms are to be con
Heeted to it holes and slots, the said stepped ends of the arms seating themselves on
the collar and being fastened in their places either by rivetting or by rivetting and
soldering substantially as described and illustrated.
Secondly. The lever catch forming part of the shade holder herein before described
and illustrated in the accompanying Drawing for fastening the shade in the
holder, whether one, or more than one of the said lever catches be used in the same
holder.
In witness whereof I the said George Atkins have hereunto set my hand and
seal this Fifth day of July in the year of our Lord One thousand eight
hundred and eighty.

GEORGE ATKINS, of the Firm of Atkins, Brothers, of Birmingham, in the
County of Warwick, Lamp and Chandelier Manufacturers. IMPROVEMENTS IN
SHADE HOLDERS FOR GAS AND OTHER LAMPS."
My Invention consists, first, of the following improvements in connecting the
radial arms of the shade holders of gas and other lamps to the screw collars or
central screwed bosses of the said bolders :-The said radial arms are ordinarily
connected to the screw collars or central screwed boss by soldering.
According to this part of my Invention, I make at the inner end of each of the
radial arms one or more studs or projections, and an abutting shoulder or stop, the
said studs and stop somewhat resembling the steps of a key, and I make across
the screw collar or central screwed boss at the part where the arın is to be con-
nected to it a hole or holes and slot, and also a seat of a size, and having a position
proper to receive the said studs and the abutting shoulder or stop. The said studs
and shoulde. stop are stamped or otherwise fashioned from the end of the arm.
When the stuus on the arm are introduced into the holes and slot in the screw
collar, and the shoulder or stop is made to seat itself upon the seat in the said
collar, the ends of the studs project slightly beyond the undersurface of the screw
collar. By expanding or rivetting the said projecting ends of the studs upon the
undersurface of the screw collar, the arm is securely connected to the said collar.
Or a single stud may be used, and the fixing be effected by soldering the end of the
arm in the slot and rivetting the single stud on the underside of the screw collar.
In this way the several radial arms of the shade holder are connected with the
screw collar or central screwed boss.
By my Invention the junction of the arms with the screw collar is stronger than
when they are connected by soldering in the ordinary way, and the liability to
fracture of the said arms at their junction with the screw collar is avoided.
My Invention consists, secondly, of the following improvements in securely
fastening the shades of gas and other lamps in their holders :-
The outer ends of the radial arms of the shade holder are provided with seats or
recesses of the ordinary kind for receiving the lower edge of the shade.
In order to fix the shade securely in its seats on the radial arms I apply to one
of the said arms a lever catch; this lever catch is jointed to the arm near the seat
of the same, and has motion in a vertical plane. The upper or fastening arm of the
said catch is so arranged on the radial arm of the holder that when the shade is
placed on the said holder the said upper arm of the catch is situated within the
catch. The lower arm of the lever catch depends below the radial arm of the
holder, and is formed into a handle for moving the said catch. The bead of the
lever catch is curved or has a figure suitable for bearing against the concave lower
edge of the shade.
After the shade has been placed in its seats on the radial arms
the handle end of the lever catch is pressed inwards or towards the centre of the
holder. The upper arm of the lever catch is thereby moved outwards, and its head
made to bear against the concave lower edge of the shade; and thereby fasten the
said shade securely in the holder. A spring may be used to press the lever catch
into its fastening position.
Although generally a single lever catch is only required, yet where a large shade
is used more than one lever catch may be employed.
I will now proceed to describe with reference to the accompanying Drawing the
manner in which my Invention may be performed.
Figures 1 and 2 represent elevations of a shade holder constructed according to,
my Invention holding a shade, the said shade being represented partly in elevation

page_text: and partly in section. The lever catch of the shade holder is represented in action
in Figure 1, and out of action in Figure 2; Figure 3 is a plan of the holder
without the shade. The other Figures represent parts of the holder as herein after
explained.
The same letters of reference indicate the same parts in the several Figures of
the Drawing.
a, a, a, are the three radial arms of the holder connected to the screw collar or
central screw boss b. One of the arms of the holder is represented in combination
with the boss b in Figure 4 and separately in Figure 5; Figure 6 represents the
screw collar or boss in section and plan separately. The inner or connecting end of
each radial arm is shaped of a figure resembling the steps of a key, that is, the
stepped end is provided with a shoulder or stop c, and also with a pin d. Across
the collar or boss b equi-distant slots e, e, e, made, and in the flange of the said collar
or boss equi-distant holes f, f, f, are made. When the stud d of the arm a is intro-
duced into the hole f, and the shoulder c into the slot e, the shoulder seats itself on
the seat at the bottom of the slot, and the stud d projects slightly from the under-
face of the collar b. The stepped part of the arm near the pin d also embraces the
flange of the collar. After the end of the arm a has been thus fitted upon the collar
the pin d is rivetted or expanded upon the under-face of the said collar, and the
stepped end of the arm is soldered in its place, or the arm a may be connected to
the collar or boss b without the use of solder. In this case I make at the stepped
end of the arm two studs d, d, and I make two holes in the collar or boss where
the arm is to be connected, in addition to the slot e, as represented in section in
Figure 7. By rivetting the two pins d, d², on the underside of the collar or boss b
the arm of the holder securely fixed to the central collar or boss.
l
The lever catch for fastening the shade g upon the holder is marked h, i, the said
catch being jointed at h³ to one of the radial arms a of the holder. When the shade
g is placed on the seats at k, k, k, near the outer ends of the arms a, a, a, of the
holder the upper part h of the lever catch is situated within the shade. The lower
or handle end i of the catch depends below the radial arm a to which the catch is
jointed, as represented. The lever catch h, i, is represented detached in Figure 8.
The head of the lever catch has a curved figure suitable for bearing against the
lower concave part of the inside of the shade. The lever catch h, i, is fixed in its
fastening position by the jointed loop on the shade holder arm engaging with the
handle end i of the said catch; this loop is shown separately in Figure 9. The
lever catch occupies the position represented in Figure 2 before the shade is placed
on the holder. After the lower edge of the shade has been placed upon the seats
at k, k, k, on the radial arms a, a, a, of the holder the handle end i of the catch is
pressed inwards or towards the centre of the holder, as represented in Figure 1. The
upper arm h of the lever catch is thereby moved outwards and its head is made to
bear against the lower edge of the shade, and thereby prevent the latter being
removed from the holder. The lever catch is fixed in its fastening position by
engaging the jointed catch with the handle end i of the said catch, as represented
in Figure 1.
In order to unfasten the shade it is necessary to turn the loop from off the
handle end i of the catch, when the latter may be moved into the position repre-
sented in Figure 2. The upper arm of the catch no longer bearing on the shade,
the said shade may be lifted from the holder. A spring may be used to press the
lever catch into the fastening position represented in Figure 1.
Instead of making the bearing edge of the head of the catch of metal the said
bearing edge may be made of india rubber, leather, or other soft material.
In this case I make the lever catch of the forked form represented in Figure 10,
and enclose between its circular upper ends a disc of india rubber or leather m,
which takes a bearing against the shade instead of the metal edge of the catch first
described.
Two or more of the lever catches described and represented may be combined in

page_text: the same holder, but for ordinary purposes only one of the said lever catches is
«
necessary.
Having now described the nature of my Invention, and the manner in which the
same is to be performed, I wish it to be understood that I claim as my Invention of
Improvements in Shade Holders for Gas and other Lamps,"
-
First. Connecting the radial arms of the said shade holders to the screw collar or
central screw boss in the manner herein before described and illustrated in the
accompanying Drawing, that is to say, making the inner ends of the radial arms of
the holder of a stepped figure or of a figure somewhat resembling the steps of a key,
and making in the screw collar or boss, at the parts where the arms are to be con-
nected to it, holes and slots, the said stepped ends of the arms seating themselves on
the collar, and being fastened in their places either by rivetting or by rivetting and
soldering, substantially as described and illustrated.
Secondly. The lever catch forming part of the shade holder, herein before described
and illustrated in the accompanying Drawing, for fastening the shade in the
holder, whether one or more than one of the said lever catches be used in the same
holder.
In witness whereof, I, the said George Atkins, have hereunto set my hand and
seal, this Fifth day of July, in the year of our Lord One thousand eight
hundred and eight
