I ALFRED EVANS of Sycamore Grove New Malden in the County of Surrey,
Gun Manufacturer do hereby declare the nature of said invention for "IMPROVE-
MENTS IN OR CONNECTED WITH GASELIERS, CHANDELIERS AND ELECTROLIERS ALSO
APPLICABLE TO THE RAISING AND LOWERING OF OTHER SLIDING APPLIANCES
be as follows:—

This invention is for improvements upon an invention for which Letters Patent
were granted to Moska Merichenski the 16th September 1882 N° 4420 for "Im-
provements in or connected with gaseliers, chandeliers and electroliers also appli-
cable to the raising and lowering of other sliding appliances" which Patent was
assigned to George Evans of Cheapside in the City of London the 16th September
1882 and the transfer thereof duly registered at the Patent Office the 16th May
1884; and the present invention refers particularly to improvements in the details
of the construction of such sliding appliances. In order to more effectually regulate
and adjust the tension of the spring contained in the barrels or drums I connect
one end of such spring to an arbor or spindle which turns in bearings in the
bracket. One end of the arbor can be turned by a handle on the outside of
the drum which winds up the spring and when sufficient tension is given to
same a cotter pin is inserted in an aperture in the arbor to hold the same, the said
pin abutting against projections formed on the bracket. When there is only a
simple or single clip as heretofore on the arbor to which the spring is hooked the
latter sometimes slips off; to prevent this I make the clip double T shaped and
swivelled whereby a firm hold is obtained for the spring and it cannot slip off the
clip. The bracket or brackets which carries the spring containing drums is or are
and
made in two parts which embrace the outer tube in which the rack travels;
at that part where the bracket embraces the tube there are small lugs or pins cast
or inserted which take into corresponding holes in the tube whereby the bracket
is prevented from slipping on the tube and the brackets are thus firmly kept in
position by the aforesaid lugs or pins; there are flanges on the bracket which are
bolted or screwed together and at the same time firmly holding the parts. Slots in
the outer tube are made to allow the teeth on the drums to take into the rack so

page_text: that when the apparatus is in use the rack is not visible. The teeth on the drum
are formed on a raised surface which allows the teeth to gear freely into the teeth
of the rack and the boxes or drums are thereby materially strengthened while the
outer tube is not weakened by cutting out much of the metal as heretofore was
necessary. The bottom or one end of the box should be made in one piece or cast
solid and the cover or lid'screwed on. For heavy pendents or bodies it is sometimes
advisable to employ a second set of drums or a series of drums according to the
weight to be suspended.
One end of the rack tube is recessed to hold the stuffing, the gas way tube
passes through the stuffing into the rack tube the latter conveying the gas to
the burners and a plug encircles the gas way tube, the said plug having on it
a throad corresponding with the thread in the recess, the said plug when screwed
down on a washer effectually compresses the stuffing round the gas way tube
thereby preventing an escape of gas and forming at the same time a means for
effectually controlling the action of the springs in the drums to the degree required.
When the slide is reversed the gas passes to the burners first through the rack
tube and thence by the gas way tube in the stuffing box. The other end of the
rack tube is screw threaded externally to receive or to hold the article to be
suspended, a gaselier for example, or this end of the rack tube may be screwed or
threaded externally to receive a "pomme!" to hold the article to be suspended.
These sliding pendents may be made of any suitable material such as brass but
they may be made of a combination of materials such as of brass and iron.
The invention is particularly applicable to pendent gaseliers, electroliers, and
pendent.lamps generally for example to outside shop lamps and pendent lamps
such as are used at railway stations, also for suspending dish covers over joints
of meat in restaurants and other places, in fact the invention is applicable in
all cases where simple and efficient means are necessary for raising and lowering
and maintaining in any desired position a suspended body or weight such as
a lamp.

I, ALFRED EVANS of Sycamore Grove, New Malden in the County of Surrey,
Gun Manufacturer do hereby declare the nature of said invention for "IMPROVE-
MENTS IN OR CONNECTED WITH GASELIERS, CHANDELIERS, AND ELECTROLIERS ALSO
APPLICABLE TO THE RAISING AND LOWERING OF OTHER SLIDING APPLIANCES" and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :—
This Invention is for improvements upon an invention for which Letters Patent
were granted to Moska Merichenski "the 16th September 1882 N° 4420 for
"Improvements in or connected with gaseliers, chandeliers and electroliers also
applicable to the raising and lowering of other sliding appliances" which Patent
was assigned to George Evans of Cheapside in the City of London the
16th September 1882 and the transfer thereof duly registered at the Patent Office
the 16th May 1884 and the present invention refers particularly to improvements
in the details of the construction of such sliding appliances.
And in order that my invention may be fully understood I will now proceed to
describe the same with reference to the accompanying drawings of which Figure 1
is a side view. Figure 2 a sectional front elevation and Figure 3 a sectional plan
of the improved chandelier. Figures 4 to 13 are detail views of the spring drum
arbor, the spring drum bracket and of various forms of stop devices applied thereto
for holding the drum springs in the wound up position.
a is the outer tube which in this examplo is shown hexagonal, b is a socket
screwed on to its upper end and adapted to be screwed into the lower part of the
usual ball and socket joint whereby the chandelier is suspended from the ceiling;
is the usual gas supply tube which when the apparatus is used as an electrolier
may serve as a passage or guide for the leads; & is the inner tube or down rod
which at the top is provided with stuffing box and gland d through which the gas
supply tube c can slide gas tight and which also steadies the down tube or rod d'in
its up and down motion, The down rod or tube d is on two opposite sides formed
with rack teeth e and is screwed onto a scrow threaded plug on its lower end as
shown or it may be fitted or formed with internal screw thread to receive a
"pommel" to hold the article to be suspended in the old or usual manner which
however is not so suitable.
In order to more effectually regulate and adjust the tension of the spring
contained in the barrels or drums g¹ I connect one end of such spring to an arbor
or spindle g³ which turns in bearings in the bracket f.
One end of the arbor can be turned by a handle which can be attached to a
square g' formed on one end of each spindle g³ on the outside of the drum g' which
handle winds up the spring and when sufficient tension is given to same a cotter

page_text: pin or other stop is inserted in an aperture in the arbor or otherwise applied
thereto in order to hold the same, the said pin or stop abutting against or otherwise
being held by projections formed or fitted on the bracket.
In Figures 1 and 3 is shewn one form of drum arbor stop and Figure 6 is a
separato side view and Figure 7 a plan section of same. The bracket f which
carries the two spring drums g¹ is fitted with a projection or screw i and k, kare
two stops provided with slots so that they can slide on and abut against the
projection or screw ȧ and provided with square cornered notches at the ends which
when passed over the square ends g of the arbors g³ hold them and the springs
attached thereto in the required tension. In Figure 8 the two stop slides kare
each with its slot working on and abutting against a separate projection or screw i,
while the other ends are each formed with a hole which at one end fits the square g¹
of the arbor and at the other end is enlarged so that the square can freely turn
therein. Figure 9 shews an equivalent arrangement in which the stops k are cach
mounted on a pivot i at one end and are formed with hook slot at the other end
which can thus be hooked onto or off the arbor square g'. Figure 10 shews a
modification in which the stops are each with a slotted end mounted on a pin i
while the other end is formed with a notched slot that can be made to fit and hold
the arbor square g. Figure 11 shews a somewhat similar form of stops k which
however both are mounted on the same pin i.
When there is only a simple or single clip as heretofore on the arbor to which
the spring is hooked the latter sometimes slips off, to prevent this I make the clip
double or T shaped and swivelled as shewn in Figure 4 which is a separate side
view and Figure 5 a plan of an arbor or spindle g³; g is the clip or button. The
end of the spring has an oblong or rectangular hole which can pass over the head
of the clip when the latter is in the dotted position whereupon the clip is turned
into the full line position whereby a firm hold is obtained for the spring and it
cannot slip off the clip. The bracket f (or brackets) which carries the spring
containing drums is shewn separately in the side view Figure 12 and plan
Figure 13. It is made in two parts which embrace the outer tube in which the
rack travels; and at that part where the bracket embraces the tube there are small
lugs or pins f1 cast or inserted which take into corresponding holes in the tube a
whereby the bracket is provented from slipping on the tube and firmly kept in
position; there are flanges f' on the bracket which are bulted or screwed together
and at the same time firmly holding the parts. Slots in the outer tube a
Figures 1, 2 and 3 are made to allow the teeth on the drums to take into the
rack e so that when the apparatus is in use the rack is not visible. The teeth g
on the drum gl are formed on a raised surface which allows the teeth to gear
freely into the teeth of the rack e and the teeth g on the boxes or drums are made
materially narrower than the side of the outer tube a into which the teeth g enter
so that the tube a is not weakened by cutting out much of the metal as heretofore
was necessary. The bottom or one end of the box should be made in one piece or
cast solid and the cover or lid g* screwed on as shewn. For heavy pendents or
bodies it is sometimes advisable to employ a second set of drums or a series of
drums according to the weight to be suspended.
When the slide is reversed or turned upside down the gas passes to the burners
first through the rack tube hd and thence by the gas way tube c which is in the
stuffing box d¹.
These sliding pendents may be made of any suitable material such as brass but
they may be made of a combination of materials such as of brass and iron.
E
The invention is particularly applicable to pendent gaseliers electroliers, and
pendent lamps generally for example to outside shop lamps and pendent lamps
such as are used at railway stations, also for suspending dish covers over joints of
meat in restaurants and other places, in fact the invention is applicable in all cases
where simple and efficient means are necessary for raising and lowering and t
maintaining in any desired position a suspended body or weight such as a lamp,

page_text: 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
First. The improved construction of the down tube or rod d that is to say
made in one piece or continuation with the tooth rack or racks e and provided
with the stuffing box d¹ substantially as set forth.
•
Second. The improved construction of bracket f for holding the spring boxes
that is to say made in two parts provided with pegs f' and having stop devices for
holding the arbors of the springs in the required position or tension substantially
as set forth.
Third. The combination of parts forming the improved gaselier chandelier or
electrolier substantially as set forth.
