Strand, London, in the County of Middlesex, Patent Agent, for the Invention
of "IMPROVEMENTS IN SUSPENDING AND ADJUSTING SLIDING GASELIERS OR
GAS APPARATUSES." A communication from abroad by Louis Clément Liotard,
of Paris. France.
Scaled the 25th February 1879, and dated the 3rd September 1878.
PROVISIONAL SPECIFICATION left by the said William Edward Gedge at
the Office of the Commissioners of Patents on the 3rd September 1878.
WILLIAM EDWARD GEDGE, of No. 11, Wellington Street, Strand, London, in the
County of Middlesex, Patent Agent. "IMPROVEMENTS IN SUSPENDING AND
ADJUSTING SLIDING GASELIERS OR GAS APPARATUSES." A communication from
abroad by Louis Clément Liotard, of Paris, France.
This Invention relates to the application of a rack to the sliding tube of a gas
pendant or gaselier. This tube slides within a fixed tube, and both are of sufficient
length to permit the gaselier or other gas apparatus to be raised or lowered to the
required height, no matter what may be its weight, without exerting much force.
A too rapid descent need not be feared becaused of the rack, and the pawl or catch
with which this apparatus is provided permits its being arrested at any desired
point.
On the accompanying Sheet of Drawing, Figure 1 is a section at A, B, Figure 2. ;
A is the fixed tube containing the gas; B, the second or sliding tube, one of the
sides of which is provided with a rack and slides freely in a recess or groove in the
box E at the entrance of the tube A. This box E is fitted at the entrance to the
main tube A to guide the tube B, and a catch or pawl F is also fitted within it for
the purpose of taking into the notches of the rack to prevent the descent of the rod
or tube B; a lever G works this pawl or catch.
The end of the tube B is provided with a union H to receive the gas apparatuses
of whatever kind. Upon the inner end of this tube B is soldered or otherwise fixed
a flanged tube. C, around which a piece of cork or suitable packing D is compressed

page_text: by means of a nut and counter-nut. This cork D forms a joint, sliding along the
tube A, and facilitates the sliding of the two tubes, the one in the other.
The mechanism shown, Figure 3, may be substituted in lieu of the pawl or catch
above described. It is composed of an endless screw S genring with a pinion P.
This pinion drives a toothed wheel K, which in its turn gears with the rack of the
tube B, and by means of the crank M the apparatus may with little exertion be
raised or lowered according to requirement.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said William Edward Gedge in the Great Seal Patent Office on the 28th

This Invention relates to the application of a rack to the sliding tube of a gas
pendant or gaselier. This tube slides within a fixed tube, and both are of sufficient
length to permit the gasclier or other gas apparatus to be raised or lowered to the
required height, no matter what may be its weight, without exerting much force.
A too rapid descent need not be feared because of the rack, and the pawl or catch
with which this apparatus is provided permits its being arrested at any desired
point.
On the accompanying Sheet of Drawing, Figure 1 is a section at A, B, Fig. 2.
A is the fixed tube, containing the gas; B, the second or sliding tube, one of the
sides of which is provided with a rack, and slides freely in a recess or groove in the
box E at the entranco of the tube A. This box E is fitted at the entrance to the
main tube A to guide the tube B, and a catch or pawl F is also fitted within it for
the purpose of taking into the notches of the rack to prevent the descent of the rod
or tube B; a lever G works this pawl or catch.
The end of the tube B is provided with a union H to receive the gas apparatus
of whatever kind. Upon the inner end of this tube B is soldered or otherwise fixed
a flanged tube C, around which a piece of cork or suitable packing D is compressed
by means of a nut and counter-nut. This cork D forms a joint, sliding along the
tube A, and facilitates the sliding of the two tubes, the one in the other.
The mechanism shown, Figure 3, may be substituted in lieu of the pawl or catch
above described; it is composed of an endless screw S, gearing with a pinion P.
This pinion drives a toothed wheel K, which in its turn gears with the rack of the
tube B, and by means of the crank M the apparatus may with little exertion be
raised or lowered according to requirement.
Having now described and ascertained the nature of the Invention com-
municated to me as aforesaid, and in what manner the same is or may be performed,
I claim, as the Invention secured to me by the herein-before in part recited Letters
Patent, the application of a rack to the sliding tube of a gas pendant, substantially
as and for the purpose herein-before described.
In witness whereof, I, the said William Edward Gedge, have hereunto set
my hand and seal, this Twenty-eighth day of February, in the year of our
Lord One thousand eight hundred and seventy-nine.
