We, RICHARD TYE, of 344, Newtown Row, Birmingham, Warwickshire; Chandelier
Manufacturer, and CHARLES HENRY ANCILL, of 56, Stafford Street, Wednesbury,
Staffordshire, Pattern Maker, do hereby declare the nature of this invention to be as
follows:-
This invention has reference to improvements in the slides of gasaliers, hanging
lamps and other like hanging gas or oil fittings which are constructed to move up or
down to vary the height of the light. The principal object of this invention is to
dispense with the usual counterbalance weight and chains by substituting therefor the
means herein described for automatically gripping or releasing the fixed rod or tube
and so retaining the moving part at any required height and allowing of its being
easily moved up or down.
This invention as applied to a chandelier is carried out as follows:-Free to slide
on the usual stationary hanging tube or rod is a gripping-piece which may consist of
a short piece of tube. This gripping-piece is furnished with a binding screw and
between the end of the binding screw and the stationary tube or rod is a metal, india-
rubber or other spring.. By turning the binding screw in one direction the gripping-
piece is tightened on the said tube or rod and by turning the binding screw in the
other direction the gripping-piece is free to be moved along the tube or rod. This
gripping-piece is situated above the usual sliding tube of the chandelier, and the said ..
binding screw is provided with a lever the outer end of which is jointed to a pin on
the said sliding tube so that when the latter is pulled down the pin thereon engaging
with the lever turns the binding screw and tightens the gripping-piece on the
stationary tube. The gripping-piece is provided with an adjustable stop with which a
projecting part of the sliding tube engages when the latter has moved down through
a certain distance and which then causes the gripping-piece and tube to move down
together.

page_text: This stop is so adjusted that when the sliding tube is pulled down in contact
therewith it has turned the binding screw just far enough to give sufficient grip on
the stationary tube to sustain the weight of the chandelier so that by a slight downward
pull it can be brought as low as required and immediately it is released it will be held
by the gripping-piece in that position.. On the chandelier being pushed upwardly the
gripping-piece remains stationary until the pin on the outer tube engaging with
the lever has turned the binding screw sufficiently to release the gripping-piece which
will then he quite free and will be pushed up by the sliding tube.
Instead of employing a binding screw having a lever which is operated by the
sliding tube we may use one or more gripping levers in the gripping-piece which are
caused to grip the stationary tube by the weight of the chandelier and to release the
stationary tube when the chandelier is pushed upwardly.
The said invention can be applied to hanging lamps and other like hanging gas or
oil fittings similarly as above described with reference to a chandelier.
The sliding joint between the stationary tube and the sliding. tube can either be the
usual water slide or any other kind of sliding joint.

Improvements in the Slides of Gasaliers, Hanging Lamps, and the
like.
We, RICHARD TYE, of 341, Newtown Row, Birmingham, Warwickshire, Chandelier
Manufacturer, and CHARLES HENRY ANCILL, of 56, Stafford Street, Wednesbury,
Staffordshire, Pattern Maker, do hereby declare the nature of this invention and in
what manner the same is to be performed; to be particularly described and ascertained
in and by the following statement:
This invention has reference to improvements in the slides of gasaliers, hanging
lamps and other like hanging gas or oil fittings which are constructed to move up
or down to vary the height of the light. The principal object of this invention is to
dispense with the usual counter-balance weight and chains by substituting therefor
the means herein described for automatically gripping or releasing the fixed rod or
tube and so retaining the moving part at any required height and allowing of its being
easily moved up or down.
This invention as applied to a chandelier is carried out as follows:-Free to slide
on the usual stationary hanging tube or rod is a gripping-piece which may consist of
a short piece of tube. This gripping-piece is furnished with a binding screw and
between the end of the binding-screw and the stationary tube or rod is a metal, india-
rubber or other spring. By turning the binding screw in one direction the gripping
piece is tightened on the said. tube or rod and by turning the binding screw in the
other direction the gripping piece is free to be moved along the tube or rod. This
gripping-piece is situated above the usual sliding tube of the chandelier and the said
binding screw is provided with a lever the outer end of which is jointed to a pin on
the said sliding tube so that when the latter is pulled down the pin thereon engaging
with the lever turns the binding screw and tightens the gripping-piece on the
stationary tube. The gripping piece is provided with an adjustable-stop with which
a projecting part of the sliding tube engages when the latter has moved down through
a certain distance and which then causes the gripping-piece and tube to move down
together.
This stop is so adjusted that when the sliding tube is pulled down in contact
therewith it has turned the binding screw just far enough to give sufficient grip on
the stationary tube to sustain the weight of the chandelier so that by a slight downward
pull it can be brought as low as required and immediately it is released it will be held
by the gripping-piece in that position. On the chandelier being pushed upwardly the
gripping piece remains stationary until the pin on the outer tube engaging with the
lever has turned the binding screw sufficiently to release the gripping-piece which will
then be quite free and will be pushed up by the sliding tube.
Instead of employing a binding screw having a lever which is operated by the
sliding tube we may use one or more gripping levers in the gripping piece which are
caused to grip the stationary tube by the weight of the chandelier and to release the
stationary tube when the chandelier is pushed upwardly.
The said invention can be applied to hanging lamps and other like hanging gas or
oil fittings similarly as above described with reference to a chandelier

usual water slide or any other kind of sliding joint.

On the accompanying drawings Fig. 1 represents in part sectional clevation a slide
for a chandelier, hanging lamp or the like constructed according to this invention;
Fig. 2 is a part sectional side elevation of the same; Fig. 3 is a similar view to Fig. 1
shewing how the weight of the chandelier or the like is carried by the gripping slide;
Fig. 4 shews the gripping spring of the same-separately; Fig. 5 represents a modifi-
cation of our invention in which gripping levers are used in the gripping piece;
Fig. 6 is a sectional elevation of the stationary tube and the gripping apparatus ;
Fig. 7 is a similar view to Fig. 5 shewing how the sliding tube is held by the gripping
levers and Figs. 8 and 9 shew the gripping part of the same separately.
Referring firstly more particularly to Figs. 1, 2, 3 and 4 a is the stationary hanging
tube (or instead of a tube a rod may be used) and is the sliding tube of the
chandelier hanging lamp or the like. e is the gripping piece furnished with the
binding screw d and containing the tubular metal spring e which is acted upon by the
binding screw d to clip the rod a. fis the lever of the binding screw the outer end
of which is connected by the link g to the pin h carried by the tube so that when the
tube bis pulled down the binding screw d will be turned and tighten the gripping
piece on the stationary tube a. i is the stop of the gripping piece which is made
adjustable by being screwed thereon. jis the projecting part of the sliding tube which
the gripping piece centers, the stop i being underneath.
The position of the stop i is so adjusted on the sliding piece c that when the
sliding tube bis pulled down so that the projecting part j comes in contact with the
stop the binding screw d will be turned just far enough to give sufficient grip on
the stationary tube or rod a to sustain the weight of the chandelier, then by a slight
extra pressure the sliding tube b can be brought as low as required and immediately it
is released it will be held in that position by the gripping piece c and screw (see
Fig. 3.) On the sliding tube being pushed upwardly (see Fig. 1) the gripping
piece c will remain stationary until the binding screw has been turned sufficiently to
release the gripping piece which will then be free on the tube a and travel up with the
sliding tube. The projecting part has a collar k a short distance below it which, when,
the tube b has been pushed upwardly far enough to release the gripping piece, comes into
contact with the adjustable stopi and carries the gripping piece before it.
We sometimes employ a binding screw and lever at each side of the gripping piece
operating similarly to the single binding screw and lever above described.
In the modification illustrated by Figs. 5, 6, 7, 8 and 9 a bracket is fixed to the
lower end of the stationary tube or rod a provided with a small hole for the gas to flow
through when gas is used. This bracket carries the gripping piece m which is by
preference a short divided tube fitting inside the sliding tube b.. n, n² are the two
gripping levers contained in the gripping piece m crossing scissors fashion and
turning on the pin o fixed to the gripping piece m. The pin o passes through a
longitudinal slot in the bracket / so, that the gripping piece m with its levers can move
either up or down through a short space. The lower end of the bracket is screw
threaded and provided with the adjustable stop i which is wedge shaped (see Figs. 5
and 7) and below the stop is the lock nut by which the position of the stop i can be
adjusted on the lower end of the bracket t.
When the sliding tube b is pulled downwardly the friction between it and the
gripping-piece m carries the gripping-piece and levers, down also so that the lower
arms of the levers are spread farther apart by coming into contact with the wedge
shaped stop thus causing their upper ends to move farther apart and squeeze the
gripping piece m, against the tube b sufficiently to sustain the weight. When the
sliding tube is pushed upwardly the gripping piece m and its levers are carried
away from the wedge-shaped stop i (see Fig. 5) so that the pressure of the gripping
levers on the gripping piece m is now released and the sliding tube is free to be
moved upwardly.
The nut can be adjusted so that when the sliding tube is pulled down the
lower ends of the gripping levers n', n will just come into contact with the nut 2

page_text: when by the wedge i they have been pushed out far enough to give sufficient grip to
sustain the weight of the chandelier, hanging lamp or the like.
It will be evident that the gripping mechanism illustrated by the accompanying
drawings will act equally well if turned upside down the tube or rob a being
movable and the tube b being stationary.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1st. The improved gripping device for the sliding and stationary tubes or tube and
rod of gasaliers hanging lamps and the like consisting of a gripping piece fitting
outside or inside one of the tubes or outside the rod and carrying a lever or levers
which when the tubes or the tube and rod are pulled outwardly is or are turned by
contact with the second tube or rod so as to bind the gripping piece into or on to the
first said tube or rod, the angular motion of the gripping lever or levers being regulated
by an adjustable stop, the said lever or levers releasing the gripping piece
when the tubes or the tube and rod are pushed inwardly all substantially as set
forth.
2nd. The construction and arrangement of parts constituting the gripping device
for the sliding and stationary tubes or tube and rod of gasaliers hanging lamps and the
like constructed and arranged. to operate substantially as hereinbefore described and
illustrated by Figs. 1, 2, 3 and 4; and the modification illustrated by Figs. 5, 6, 7, 8
and 9 of the accompanying drawings.
