PROVISIONAL SPECIFICATION.
Improvements in or applicable to Gas-chandeliers.
We SAMUEL GRATRIX JUNIOR AND BROTHER LIMITED, Lead Merchants
and HENRY BROCKLESBY Foreman both of Alport Town Manchester in the
County of Lancaster, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the construction of gas chandeliers the object being to
dispense with the use of weights and water or lute joints and with the necessity for
detachable "pendu lights."
For this purpose we make the chandelier with a straight vertical pipe as usual
and with the ordinary arms supporting globes and burners, and by preference
curved downwards so as to form a space at the end of the straight vertical pipe,
which we provide at this point with a suitable stuffing box through which passes a
pipe of smaller diameter free to slide up and down in the said vertical pipe. The
latter is not supported as usual by weights and chains but is a fixture, and the
stuffing box at its end is such that it can be tightened up to support the weights of
the smaller pipe and its appurtenances hereafter described.
At the end of the smaller pipe we fit or form a curved tubular arm provided at
its lower end with a short horizontal or curved tubular arm carrying at its end a
burner and gallery for supporting a globe. This last named arm is so fitted to the
end of the curved arm that it can swivel round thereon and bring the gas globe to
any desired position round the centre of the fixed vertical pipe.
The upper end of the smaller sliding pipe is open for the admission of the gas
and is provided with a cork fitting into the fixed pipe. Openings are made in the
sliding pipe below this cork to admit the gas to the fixed pipe to supply the
ordinary arms of the chandelier, and a suitable stop is providel near the bottom
of the said fixed pipe to prevent the cork from being drawn down too low
therein.
It will be understood from the above description that should a light be required
at a level lower than that of the ordinary globe of the chandelier, the central globe
which is supported by the stuffing box and small inner pipe can be pulled down to
the level required and moved into any position by turning the smaller pipe in the
stuffing box, and the short tube (supporting the said central globe) upon its centre
before named.
When this central globe is not required it can be brought immediately beneath
the centre of the chandelier and pushed up out of the way.
By these means we dispense with the necessity for weights, lute joints, and
removable "pendu" lights.
It is evident that our improvements may be applied to many existing chandeliers
if desired.

Improvements in or applicable to Gas-chandeliers.
We SAMUEL GRATRIX JUNIOR AND BROTHER LIMITED, Lead Merchants,
and HENRY BROCKLESBY Foreman both of Alport Town Manchester in the
County of Lancaster, 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 relates to the construction of gas-chandeliers the objects being to
dispense with the use of weights, and water or lute joints, and with the necessity for
detachable "pendu-lights."
The nature of the said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference
to the annexed sheet of drawings and the following explanation thereof.
Fig. 1 on the drawings is an elevation of a gas chandelier made according to our
invention, and
Fig. 2 is partial vertical section thereof drawn to an enlarged scale.
For the purposes of our invention we make the chandelier with a straight vertical
pipe a as usual and with the ordinary arms supporting the burners and globes c,
and by preference, curved downwards (as shown at Fig. 1) so as to form a space
beneath the lower end a' of the straight vertical pipe a which we provide at this
point with a suitable stuffing-box d through which passes an inner pipe e of smaller
diameter which is free to slide up and down in the said vertical pipe a.
The latter is not supported by the usual weights and chains but is a fixture,
and the stuffing-box d at its end is such that it can be tightened up to grip and
support the weight of the smaller pipe e and its appurtenances hereinafter
described.
At the lower end of the smaller pipe e we fit or form a curved branch provided
at its lower end with a short horizontal (straight or curved) tubular arm carrying
at its end a burner and gallery for supporting a globe c'. This arm g is so fitted
to the end of the curved branch that it can swivel round thereon and bring the
gas globe c¹ into any desired position round the centre of the fixed vertical pipe a.
The socket or joint ground which the arm g swivels is preferably made in the
form of a tap which is closed when the globe e¹ is under the centre of the pipe a
but is opened when the pipe e is drawn down and the army turned outwards (as
shown by the dotted lines) so that the central burner c' cannot be lighted until it
is first placed in the proper position for use, and it cannot be returned into its
central position without putting out the light. This form of tap is well-known to
gas and water fitters.
The upper end e of the smaller sliding pipe e (see Fig. 2) is made open for the
admission gas, and is provided with a cork & tightly fixed thereon and fitting and
sliding up and down in the fixed pipe. Openings are made in the sliding pipe e
below this cork to admit the gas to that part of the fixed part which is below the
cork h, and a suitable stop k and buffer spring are provided at or near the bottom
of the fixed pipe a to prevent the cork from being drawn down too low therein.
The cork can therefore never be drawn down to the junction of the pipe a' and
the arms to which the gas can at all times gain access through the aforesaid
opening or openings i.
It will be understood from the above description that should a light be required
at a lower level than that of the ordinary globes c of the chandelier the central
globe which is supported by the stuffing box d and small inner pipe e can be
pulled down to the level required and moved into any position by turning the
pipe e in the stuffing-box d and the short arm g (supporting the said central
globe e¹) upon its centre, as shown by the dotted lines on Fig. 1 and when this
central globe d is not required it can be brought immediately beneath the centre of

page_text: the chandelier (which movement will put out the light) and it can then be pushed
up out of the way as drawn in full lines at Fig. 1.
By these means we dispense with the necessity for weights, chains, lute-joints,
and removable "pendu "-lights.
It is evident that our improvements may be applied to many existing chandeliers
if desired.
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 :-
The combination with a gas-chandelier having a fixed gas-supply pipe and radial
branches or arms of an inner sliding and swivelling pipe of smaller diameter
passing out through a stuffing box and fitted with an additional burner and globe,
constructed and arranged in such a manner that the gas can at all times gain
access to the branch pipes and to the inner sliding pipe substantially as and for the
purposes hereinbefore described and illustrated by the annexed drawings.
