page_text: LETTERS PATENT to Moska Merichenski of Stainsby Road Poplar in the
County of Middlesex for an Invention of "IMPROVEMENTS IN OR CONNECTED
WITH GASELIERS, CHANDELIERS AND ELECTROLIERS ALSO APPLICABLE TO THE
PROVISIONAL SPECIFICATION left by the said Moska Merichenski at the
Office of the Commissioners of Patents on the 16th September 1882.

"IMPROVEMENTS IN OR CONNECTED WITH GASELIERS, CHANDELIERS AND
ELECTROLIERS ALSO APPLICABLE TO THE RAISING AND LOWERING OF OTHER
SLIDING APPLIANCES
"
My invention refers to improved apparatus for raising and lowering and for
keeping the article or articles suspended in any desired position that may be
required by simple and effective means as hereafter described.
The invention is applicable to sliding appliances generally but for the sake of
clearness I will describe the invention as applied to a gaselier.
The outer tube of pendant or down rod may be round square or of any other
convenient shape; inside this outer tube there is another tube also of any desired
shape which is cogged or milled all round or only on those portions (which are
presented to the action of toothed wheels or cogged or milled surfaces. These
cogged or milled surfaces are made in a piece with or mounted on the periphery
of boxes which contain a coiled spring or springs or a spring similar for example
to the mainspring of a clock.
As the rack rod is pulled down the box wheels are revolved and the springs
wound up, on releasing the rack rod the same remains stationary in the position
desired owing to the weight of the chandelier, gaselier or electrolier or other
appliance compensating for the action of the spring.
The gas way or passage (in the case of an electrolier for the wires) is connected
in the usual manner to the ball joint for suspension and passes through the
down rod.
As applied to shutters windows and other sliding appliances the arrangements
are only necessarily varied according to the purpose to which the invention is
applied

the said Moska Merichenski in the Great Seal Patent Office on the
16th March 1883.
MOSKA MERICHENSKI of Stainsby Road Poplar in the County of Middlesex
" IMPROVEMENTS IN OR CONNECTED WITH GASELIERS, CHANDELIERS AND
ELECTROLIERS ALSO APPLICABLE TO THE RAISING AND LOWERING OF OTHER
SLIDING APPLIANCES

My Invention refers to improved apparatus for raising and lowering and for
keeping the article or articles suspended in any desired position that may be required
by simple and effective means as hereafter described.
The Invention is applicable to sliding appliances generally I will describe the
Invention as applied to a gaselier.
The outer tube of pendant or down rod may be round square hexagonal or of
any other convenient shape in cross section; inside this outer tube there is another
tube also of any desired shape in cross section which is cogged or milled either all
round or only on those portions which are presented to the action of toothed
wheels or cogged or milled surfaces. These cogged or milled surfaces are made in
a piece with or mounted on the periphery of boxes which contain a coiled spring
or springs or a spring similar for example to the main spring of a clock.
Figure 1 of the accompanying drawings is a side elevation of so much of the
pendant or down rod of a gaselier constructed according to my Invention as will
be necessary to explain the same Figure 2 is a longitudinal vertical section and,
Figure 3 is a side elevation of the same at right angles to Figure 1. Figure 4 is a
horizontal section on line A, B, of figure 2. Similar letters of reference refer to
like parts in all the Figures a is the outer tube of the pendant or down rod
which in the example shewn is hexagonal; b, is the ball and socket or swinging
joint whereby the outer tube a is suspended from the ceiling of room or other
place in the ordinary way; c is the gas supply tube which when the appliance
is used as an electrolier might serve as a passage or guide for the wires conveying
the electric current to the electrodes; d is the inner tube of the down rod which
is screwed into or carries on the top a stuffing box d' (through which the gas tube c
slides) in order to prevent escape of gas and for steadying the gaselier in its
upward and downward motion and at the same time forms a shoulder against
which the rack e abuts; e is this rack which in the example shown is slipped on
to the tube d and abuts against the stuffing box d¹ at the top; f is the bracket or
brackets made in a piece with or secured to a collar keyed or otherwise secured to
the outer tube a; g g are the teeth or toothed wheels on the periphery of the
boxes g; which wheels or equivalents are in gear with the teeth of the rack e; in
some cases I may as shown discontinue the teeth on the rack e, below the toothed
wheels g' forming the lower continuation of this rack of a plain piece of piping e'
so that on the tube d being drawn down the teeth are not disclosed to view; as
seen at Figure 1; the end of rack e is prevented passing the wheels g by the
stuffing box against which it abuts. These boxes contain the springs g coiled
round the axis g³ which is fixed to the frame or bracket f the other end of
spring is fixed to the inner periphery of the box g¹ as shown.
The gaselier or electrolier is screwed on or otherwise connected to the end of
the rod d at the point marked h by means of a "pommel" in the ordinary manner.
The action is as follows; when the tube d is pulled down carrying with it the
rack e, the box wheels g, g, are revolved and the springs in same are wound up, on
releasing the tube d the same has a tendency to rise but remains stationary at the

page_text: position desired owing to the weight of the chandelier gaselier or electrolier or
other appliance which is connected thereto aided by the friction of the stuffing
box on the central tube thereby providing or acting as a resistance to the action
of the spring sufficient to balance its elastic force The pendent or down rod may
be ornamented as fancy or taste may dictate.
The gas way or passage, which in the case of an electrolier may be dispensed with
or used for the wires as found most convenient is connected in the usual manner
to the ball joint for suspension and passes through the stuffing box and the down
rods as shown
As applied to shutters windows and other sliding appliances the arrangements
are as hereafter described with reference to Figure 5 substantially the same as
when the Invention is applied to a gaselier or electrolier but only necessarily
varied according to the purpose to which the Invention is applied. The wheels and
rack may be made of metal, vulcanite or any suitable material.
Figure 5 shows in vertical section this application of the Invention as applied to
a window casement for example to the window of a railway carriage or other place
where the sashes slide up and down in their frames; the rack e is on the side of
the sash and the boxes g' are shown fitted into recesses formed in the sash frames
or the boxes g' may be fitted onto the sash and the rack supported or attached to
the sash frame.
Having now described the nature of my said Invention and in what manner the
same is to be performed I declare that I claim
First: In a chandelier gaselier or electrolier the combination of a toothed rack
with toothed wheels (the latter acting on springs which are wound or released
according to the direction in which the wheels rotate) for raising and lowering
and regulating the position of the pendants or down rods of said chandeliers
gaseliers or electroliers all acting substantially as and for the purpose; as set forth.
Second-The application of the arrangement described to sliding appliances
generally and particularly as applied to the raising and lowering of window
sashes and frames and substantially as set forth.
In witness whereof I the said Moska Merichenski have hereunto set my
hand and seal this Twelfth day of March in the year of our Lord One
thousand eight hundred and eighty three.
