PROVISIONAL SPECIFICATION.
Improvement in Gas Chandeliers and Pendant.
1, ROBERT HALL. BEST of Cambray Works, Handsworth in the County of Stafford,
Chandelier Manufacturer do hereby declare the nature of this invention to be as
follows:-
My invention has for its object the production of an improved Stuffing Box Rod
for Gas Chandeliers or Pendants, such that in spite of the fact of its being balanced
by one Annular Weight, rather than the several independent weights, or even the
large annular one, yet that it shall have the advantage of a long stroke without danger
from collision, the one part within the other in passing.-Where the annular weight
has been used, it has hitherto been necessary to accept a much more limited stroke, on
account of the difficulty & danger of passing the projecting parts at the head of the
sliding tube safely past the weight in opposite directions at anything like speeds
corresponding to ordinary rough handling; or else adopt a much larger annular weight
to avoid in a great measure the chances of such a collision-In order to accomplish
this my object I provide, firstly. That the internal diameter of the annular weights
shall be large enough to ensure a free passage through it for the head of the sliding
tube, & its appendages, secondly, but by preference only, that internally it shall be
bevelled or rounded off at top and bottom, & thirdly, that the Chain connections at
the head of the sliding tube shall be so made, for example, by raking back the chain
to the rod as the equivalent of an incline plane, as to avoid abrupt projections, or
what will be better still, that they shall be encircled by a shield fixed thereto in the
which such projections are avoided by providing the corresponding level or curve on
it as before described relative to the weight,-By 50 doing, any tendency to collide the
one in the other is received as it were on one or more incline planes, & thereby
en-uring that such parts merely glide past each other without shock or damage after

page_text: contact, should there be such whilst the tight chains passing upward to their respec-
tive pullies serve also the further purpose of guiding the Weight, & shielding the
inside rod or tube from collision with the now swinging weight-When it is
remembered that the passage of the one part through the other virtually doubles the
speed at the moment of collision, then the importance of this invention will be better
understood, As before mentioned indirectly, by this method, having guarded against
the danger of passing the one part through the other, the full stroke rather than half
may be adopted, whilst the further advantage is obtained of not having to pull straight
down since now the whole apparatus may be handled much more roughly or carelessly
with impunity.

I, ROBERT HALL BEST of the Firm of Best & Lloyd Chandelier Manufacturers
Cambray Works Handsworth near Birmingham do hereby declare the nature of my
invention for IMPROVEMENTS IN GAS CHANDELIERS and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
My Invention has for its object the production of an improved Gas Chandelier or
sliding pendant containing the usual appurtenances of both stuffing box & counter-
weight which improvements are such that in spite of the fact of the chandelier being
balanced by one annular weight rather than the several independent ones yet that it
shall have the advantage of a long stroke without danger from collision in passing the
one part without the other.
Where the annular weight has been used it has hitherto been necessary to accept a
much more limited stroke than otherwise on account of the difficulty & danger of
passing the projecting parts at the head of the sliding tube safely past the weight in
opposite directions at anything like speeds corresponding to those of ordinary rough
handling, or else to adopt a much larger weight internally considered in order in a
great measure to avoid such chances of colli-ion.
In order to accomplish this my object I provide firstly that the internal diameter of
the annular weight shall be large enough to ensure a free passage through it for the
head of the sliding pipe & its appendages secondly but by preference only that
internally it shall be bevelled or rounded off top & bottom, & thirdly that the chain
connections at the head of the sliding pipe shall be so made as to avoid abrupt pro-
jections for example by raking back the (hain to the rod as an equivalent of an
inclined plane or what will be better still that they shall be encircled by a shield fixed
thereto in the which such projections are avoided by providing the corresponding
bevel or curve on it as before described relative to the weight.
By so doing any tendency to collide the one in the other is received as it were on
one or more inclined planes & thereby ensuring that such parts merely glide past each
other without shock or damage after contact should there be such, whilst the tight
chains passing upwards to their respective pulleys serve also the further purpose of
guiding & shielding the spigot or hanging pipe from collision with the now swinging
weight.
When it is remembered that the passage of the one part through the other virtually
doubles the speed at the moment of collision then the importance of this invention
will be better understood.
As before mentioned indirectly by this method having guarded against the danger
of passing the one part through the other the full stroke rather than the half may be
adopted whilst the further advantage is obtained of not having to pull straight down
since now the whole apparatus may be handled much more roughly or carelessly with
impunity.

page_text: Figure 1 is an example as described arranged & provided with inclined planes.
Figure 2 is another example arranged & provided with raking chains in lieu of
inclined planes.
In each such view like letters correspond to like parts, & are as follows
A is the annular weight with the rounded internal corners D.
B the sliding tube with its head marked ('.
E the chain connections.
F the inclined planes, & H. the equivalent raking chains.
Having now particularly described & ascertained the nature of my said Invention,
& in what manner the same is to be performed I declare that what I claim is
(1) The combination with a sliding stuffing box pendant & annular weight of an
inclined plane or planes fixed around the sliding tube substantially as & for the purpose
herein before described.
(2) The combination as in the preceding claiming clause except that instead of the
inclined plane or planes raking chains are substituted substantially & for the purpose
herein before described.
(3) The arrangement & combination of parts constituting the several construc-
tions of the pendant herein before described & illustrated in Fig. 1 & 2 respectively of
the accompanying drawings.
