PROVISIONAL SPECIFICATION left by the said Moska Merichenski at the
Office of the Commissioners of Patents on the 2nd September 1881.

"A NEW OR IMPROVED APPARATUS FOR RAISING AND LOWERING GASELIERS
AND CHANDELIERS, ALSO APPLICABLE TO OTHER PURPOSES."
My Invention relates to a new or improved means of and apparatus for raising
and lowering the sliding parts of gaseliers and chandeliers, also applicable to cork-
screws or other appliances having a like action.
My Invention consists, when applied to gaseliers and chandeliers, in the appli-
cation and use of a screw or worm placed centrally within the fixed portion or case
of the gaselier or chandelier, its bottom end being mounted on a pivot at the
bottom of the case, and its upper end formed with a square recess, into which is
inserted a square pivot or bar, which passes up into a box, where it is attached to
a spiral spring (similar to that of a watch or clock). This box with its appendages
described is secured to the ceiling of the room or building in any suitable
manner.
On the central screw or worm is fitted a nut with opposite arms, which pass
through corresponding slots in the case, and carry at their ends the sliding pipes
of the gaselier, or the carrying tubes of the chandelier (as the case may be).
On pulling down or lowering the sliding pipes or carrying tubes the nut
travelling along the screw or worm causes it to revolve and wind up the spiral
spring at the top. When raising the sliding tubes the reaction of the spring
causes the screw or worm to revolve in the opposite direction, so as to raise the

page_text: nut, thereby reducing the pressure required to raise the sliding pipes by the hand
to a minimum, or not exceeding that necessary when weights are used; the latter
in this case are entirely dispensed with.
For conveying the gas from the main pipe to the sliding pipes in the case of
gaseliers, the gas passes through a pipe or pipes by the side of the spring box or
near thereto, and thence through flat hollow links swivelled together at the sides,
so as to form connecting ducts or chains communicating with the upper ends of the
sliding pipes. When the sliding pipes are raised as above described, these ducts or
chains spread out or accommodate themselves to the movement.
In applying my Invention to cork screws the central screw is pivoted in the
handle and bottom of the case or frame, the cork screw forming an external
continuation of the central screw. The nut with its arms being in the lowest
position in the case or frame, by passing the hand over the handle and laying hold
of the arms of the nut with the fingers, the nut is raised towards the handle, and
the central screw with the corkscrew being thereby caused to rotate the latter is
introduced into the cork without turning the handle.

"A NEW OR IMPROVED APPARATUS FOR RAISING AND LOWERING GASELIERS
AND CHANDELIERS, ALSO APPLICABLE TO OTHER PURPOSES."
My Invention relates to a new or improved means of and apparatus for raising
and lowering the sliding parts of gaseliers and chandeliers, also applicable to cork
screws or other appliances having a like action.
On the accompanying Drawing Figure 1 is a vertical section illustrating my
Invention as applied to gaseliers and chandeliers, according to which arrangement
I make use of a screw or worm a placed centrally within the fixed portion or case b
of the gaselier or chandelier, its bottom end being mounted on a pivot c at the
bottom of the case b, and its upper end formed with a square recess, into which is
inserted a square pivot or bar d, which passes up into a box e, where it is attached
to a spiral or coiled spring f (similar to that of a watch or clock). This box e with
its appendages, as described, is secured to the ceiling of the room or building
in any suitable manner. On the central screw or worm a is fitted a nut g with
opposite arms h, h, which pass through corresponding slots i in the case b, and
carry at their ends the sliding pipes (shown broken away) of the gaselier, or the
carrying tubes of the chandelier (as the case may be). On pulling down or
lowering the sliding pipes j (or carrying tubes), the nut g travelling along the
screw or worm a causes it to revolve and wind up the spiral spring fat the top,
and on raising the sliding pipes the reaction of the spring f causes the screw or
worm a to revolve in the opposite direction, so as to raise the nut g, thereby
reducing the pressure required to raise the sliding pipes by the hand to a minimum,
or not exceeding that necessary when weights are used, which in this case are
entirely dispensed with.
For conveying the gas from the main pipe to the sliding pipes ; in the case of
gaseliers, the gas passes through a pipe (or pipes) k by the side of the spring box e
or near thereto, and thence through flat hollow links swivelled together at the
sides, as shewn, so as to form connecting ducts or chains which communicate with
the upper ends of the sliding pipes j, and which, when the latter are raised as
above described, spread out or accommodate themselves to the movement.
Figure 2 is a sectional elevation, shewing a modified form of my Invention, in
which the worm or screw a¹ in lieu of extending the entire length of the central
tube (or bar) m, as in Figure 1, is formed only for a short distance thereon at its
lower (or upper) end. This spiral portion a¹ of the central tube (or bar) m works
in a corresponding worm or thread formed on the entire length of the interior of
the case or elongated nut b¹. The central tube (or bar) m is enclosed by a second
tube constituting the sliding pipe of the gaselier (or carrying tube of the
chandelier, as the case may be), and formed with longitudinal slots o, taken into
by tongues or pieces p (in combination or not with friction rollers) on the case or
elongated nut b¹ for preventing the tube n (or sliding pipe) from turning. In this
arrangement the arms h, h, shewn in Figure 1, may be dispensed with if desired.
On pulley down the case or elongated nut b¹ of the gaselier the the worm or screw
on its internal surface causes the spiral portion a¹ with the inner central tube (or
bar) m to rotate, and in so doing the latter winds up the spiral or coiled spring f
at the top. On raising the case or elongated nut 61 the reaction of the spring f
causes the central tube m and its spiral portion a¹ to revolve in the opposite
direction, and so easing the weight of the gaselier or chandelier in a similar

page_text: to that described in Figure 1; or if desired the case or elongated nut b¹ may be
fixed to the ceiling, and the tube or sliding pipe n pulled up and down. The gas
is conveyed to the burners of the gaseliers through a third tube q passing through
the central tube m and through a stuffing box at its lower end to prevent the
escape of gas. My Invention may be applied to any other purposes where a raising
and lowering action is required, such as for electric lamps or chandeliers, shutters,
and others. Amongst its advantages are that the water hitherto used in hydraulic
chandeliers is dispensed with, and no weight being required, danger is avoided.
Figure 3 shews the application of my Invention to cork screws, in which case the
central screw is pivoted in the handle s and bottom of the case or frame t, the
corkscrewforming an external continuation of the central screw r.
The nut u
(with its arms v) is prevented from turning by bars w secured to the handle and
being in the lowest position in the case or frame t, by placing the hand over the
handles and laying hold of the arms v of the nut w with the fingers the nut u is
raised towards the handle s, and the central screw with the corkscrew r¹ being
thereby caused to rotate the latter is introduced into the cork without turning the
handle 8.

Having now described and particularly ascertained the nature of my said
Invention, and the manner in which the same is or may be used or carried into
effect, I would observe in conclusion that what I consider novel and original and
therefore claim as my Invention is,―
1. To gaseliers or chandeliers the application and use of a worm or screw in
combination with a nut, or with an equivalent case or elongated nut, and with a
central tube (or bar) actuating a spring, substantially as and for the purposes
herein before described and illustrated by Figures 1 and 2 on the accompanying
Drawing.
2. The application and use to corkscrews of a worm or screw in combination
with a nut having arms and slots in combination with bars and with the handle,
substantially as and for the purpose hereinbefore described and illustrated by
Figure 3 on the accompanying Drawing.
In witness whereof, I, the said Moska Merichenski, have hereunto set my
hand and seal, this Twenty eighth day of February, in the year of our Lord
One thousand eight hundred and eighty-two.
