PROVISIONAL SPECIFICATION.
An Improved Device to Limit the Downward Movement of
Chandeliers.
I, ARTHUR JAMES WHITE, of 47 and 61 Atlantic Road, Brixton, in the County
of Surrey, Ironmonger, do hereby declare the nature of this invention to be as
follows:-
My invention relates to an improved device to limit the downward movement of
chandeliers.
It is well known that with chandeliers in which the portion carrying the burners
slides upon a central tube it is easily possible for the said sliding portion to be
moved too far down so as to allow gas to escape from between the inner and
outer tubes. Moreover in such a case the balance weights may be drawn over
the pulleys, causing inconvenience, and, in certain cases, producing the danger of
the disengagement of the weights and damage to the chandelier, with the chance of
injury to persons in its neighbourhood.
The object of my invention is to provide a cheap simple and efficient device
whereby the downward movement of the chandelier is limited.
According to my said invention I secure upon the main or movable tube of
the chandelier a collar or clip fitted with arms the number of which preferably
corresponds with the number of balance-weight chains. The said arms have
openings in their ends, through which openings the free ends of the balance-weight
chains are passed, so that the balance weights are below the end of the arms.
Therefore when the chandelier is lowered and the balance weights consequently
rise, the upward movement of the said weights will be limited by the said arms,
with which they will come in contact; the prevention of the upward movement of
the weights, and of the free ends of the chains will simultaneously stop the
downward movement of the chandelier depending from the other ends of the said
chains.
The said collar or clip may be secured at any suitable point upon the said main
tube and is so constructed that it may be very readily applied to existing chandeliers.
I do not limit myself to the particular arrangement hereinbefore described by way
of example, as the apparatus may obviously be varied without departing from the
nature of my invention. It may be attached to the fixed tube instead of to the
movable one. Or as an alternative the said collar may be arranged so that
the arms attached thereto rest upon the balance weights and the collar itself slides
loosely upon the central tube of the chandelier. In such a case the cup commonly
fitted at the upper end of the said tube would serve to limit the upward movement
of the collar and the weights, or a special stop could be applied to the tube for a
like purpose. The device may be made either plain or ornate, and of any suitable
material.

1, ARTHUR JAMES WHITE, of 47 and 61 Atlantic Road, Brixton, in the County
of Surrey, Ironmonger, do hereby declare the nature of this invention and in wha
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :-
My invention relates to an improved device to limit the downward movement of
chandeliers, and to prevent the accidental disengagement of the balance-weights
therefrom.
It is well known that with chandeliers in which the portion carrying the burners
slides upon a central tube it is easily possible for the said sliding portion to be
moved too far down, so as to allow gas to escape from between the inner and outer
tubes. Moreover, in such a case, the balance weights may be drawn over the
pulleys, causing inconvenience, and, in certain cases, producing the danger of the
disengagement of the weights and damage to the chandelier, with the chance of
injury to persons in its neighbourhood.
The object of my invention is to provide a cheap, simple, and efficient device,
whereby the downward movement of the chandelier is limited, and whereby the
accidental disengagement of the weights is prevented.
In order that my said invention may be clearly understood, I will now proceed
to describe the same with reference to the accompanying drawings, in which
Figure 1 is a side elevation of a two-light chandelier fitted with improvements
according to my invention,
Figure 2 is a plan of an attachment according to my invention, suited for a
three-light chandelier, and
Figure 3 is a side elevation of a chandelier weight, fitted with means whereby
it is prevented from becoming accidentally disengaged from such an attachment as
is illustrated in Figure 2.
With reference first to Figure 1, A. is the main or movable tube of the chandelier.
BB are branches thercon, which carry burners and shades in the usual manner.
C is the stationary tube by which gas is supplied to the chandelier. D is
a collar, capable of sliding freely upon the tube A, and provided with arms E,
the number of which corresponds with the number of balance-weight chains.
FF are the balance-weights. G G are the balance-weight chains, which pass
from the upper end of the tube A over stationary pulleys H arranged in the usual
manner, and thence to the weights F. A is a cup or stop secured to the upper
end of the tube A and utilized for the purposes of my invention as hereinafter
set forth.
The ends of the arms E rest upon the weights F as shown, so that when in
the descent of the chandelier the said weights rise, they raise the arms E and
collar D until the said collar comes into contact with the cup or stop A' and further
downward movement of the chandelier is prevented. The disadvantages and
danger hereinbefore referred to as incident to the use of chandeliers without the
said collar and arms are thus obviated.
I preferably attach the weights F to the arms E, so that in the event of
breakage of the chain by which a weight is suspended, the said weight will not
be permitted to fall but will be held by the end of the arm.
As an example of one method in which this portion of my invention can be
carried into effect I now refer to Figures and 3. In the ends of the arms E,
slots E' are provided, and at the upper end of each weight F an eye or flattened
portion F is provided which has a neck or reduced portion F below it. The eye
or flattened portion is to be passed through any of the slots E' and the weight
then turned round so that the overhanging portions of the eye or. flattened

page_text: portion F¹ will rest upon the end of the arm and will not return through the slot
unless the weight is intentionally turned round to permit them to do so. Thus
the accidental detachment of the weight from the chandelier is prevented.
I do not limit myself to the particular method of fastening the weight to the
arm hereinbefore given by way of example, as I may obviously adopt other forms
of fastening without departing from the nature of my invention.
As an alternative I secure the collar D upon the tube A, and pass the chains G
through openings in the ends of the arms; therefore when the chandelier is
lowered and the balance weights consequently rise, the upward movement of the
said weights will be limited by the said arms, with which they will come in
contact; the prevention of the upward movement of the weights and of the free
ends of the chains will simultaneously stop the downward movement of the
chandelier depending from the other ends of the said chains.
The said collar can be secured at any suitable point upon the said main
tube and can be so constructed that it may be very readily applied to existing
chandeliers.
The aforesaid collar D with the arms thereon may be either fixed to or arranged
to slide upon the stationary tube C instead of upon the movable tube A.
Where the said collar is arranged to slide upon the stationary tube, the stop
for limiting the upward movement of the collar would also be fixed to the said
tube.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The several devices for limiting the downward movement of chandeliers,
substantially as hereinbefore described.
2. The combination with the balance-weights of a chandelier, of arms attached
thereto and to a ring or equivalent device which operates to limit the downward
movement of the chandelier, substantially as hereinbefore described for the purpose
specified.
3. A chandelier having any of my improvements applied thereto substantially
as hereinbefore described with reference to the accompanying drawings, for the
purposes specified.
