PROVISIONAL SPECIFICATION.
Improvements in or relating to Gas Brackets or Pendants, and in
Shades or Reflectors applicable therefor.
We, HUGH CRAWLEY and GEORGE ANTHONY METCALFE, trading together
as William Bayliff of 9 Tyrer Street, Liverpool in the County of Lancaster,
Billiard Table Makers, do hereby declare the nature of this invention to be as
follows:-
This invention relates to certain improvements in the construction of gas
brackets or pendants and in shades or reflectors applicable therefor. It is designed
largely for use in connection with billiard tables, for throwing a powerful concen-
trated light over the whole surface of the table while reducing the number of jets
required, though we wish it to be understood that we do not confine the invention
to billiard tables only, as it is applicable for other purposes besides.
In carrying the invention into effect, the gas bracket or pendant is made of
suitable design, having horizontal arms, at the ends of which, gas jets are located,
which however are arranged on a somewhat lower plane than the horizontal arms
of the pendant, so that the said horizontal arms will be clear of the jets and will
not in any way obstruct the lighting of the billiard table or other object. This is
secured by forming at the end of each horizontal arm a small downwardly
projecting bent gas pipe, the upward bend of which is fitted with the burner and
does not reach as high as the plane of the horizontal arms. Each jet is provided
with square or rectangular shades or reflectors, which are preferably formed of
cardboard, though any other suitable material may be used if desired. These
square shades or reflectors are a great improvement on the old fashioned circular
cardboard shades as while they are adapted to throw a powerful concentrated light
onto the table or other object, they will throw it over a larger area than was
possible for a circular shade to do. Each shade or reflector is mounted on a
bracket or gallery supported by means of sleeves on the horizontal arms of the
pendant, these sleeves being adjustable horizontally and capable of being locked
by means of a milled headed screw. Each shade or reflector is cut away slightly
on one side to allow of the passage of the horizontal arms.
We have described the above way in which our invention may be carried into
effect, but we wish it to be understood that we do not confine ourselves to the
arrangement described, as the same may be altered in its details without departing
from the invention, moreover our improved shades or reflectors of square or
rectangular shape may be applied to any suitable bracket pendant or lamp and we
do not confine their use to the pendant we have described."

Shades or Reflectors applicable therefor.
We, HUGH CRAWLEY and GEORGE ANTHONY METCALFE,. trading together
as William Bayliff, of 9, Tyrer Street, Liverpool in the County of Lancaster,
Billiard Table Makers, 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 certain improvements in the construction of gas
brackets or pendants and in shades or reflectors applicable therefor. It is designed
largely for use in connection with billiard tables, for throwing a powerful concen-
trated light over the whole surface of the table while reducing the number of jets
required, though we wish it to be understood that we do not confine the invention
to billiard tables only, as it is applicable for other purposes besides.
The invention will be understood from the following description, reference being
had to the accompanying drawings in which
Figure 1 is a general view of our improved gas bracket or pendant with its
shades or reflectors;
Figure 2 a sectional elevation of the burner and shade ;
Figure 3 a detail view.
In these figures, A is the gas bracket or pendant which is made of any suitable
design, having horizontal arms B, at the ends of which gas jets C are located,
which however are arranged on a somewhat lower plane than the horizontal arms B
of the pendant, so that the said horizontal arms will be clear of the jets and will
not in any way obstruct the lighting of or throw a shadow upon the billiard table
or other object. This is secured by forming at the end of each horizontal arm B
a small downwardly projecting bent gas pipe D, the upward bend of which is fitted
with a burner C and does not reach as high as the plane of the horizontal arms B.
Each jet is provided with square or rectangular shades or reflectors E, which are
preferably formed of cardboard, though any other suitable material may be used
if desired. These square shades or reflectors are a great improvement on the old
fashioned circular cardboard shades, as while they are adapted to throw a powerful
concentrated light on to the table or other object they will throw it over a larger
area than was possible for a circular shade to do. Each shade or reflector is
mounted on a bracket or gallery F supported by means of sleeves G on the hori-
zontal arms B of the pendant, these sleeves being adjustable horizontally and
capable of being locked by means of a milled headed screw H. Each shade or
reflector is cut away slightly on one side at I, to allow of the passage of the
horizontal arms B.
By the present invention the plan sometimes adopted of locating the gas jet
immediately underneath the elbow from which the burner is suspended is dispensed
with, and thus the disadvantage of the elbow soon wearing out by the action of
the heat of the flame is entirely overcome. The arrangement of the bracket or
gallery enables the shades or reflectors to be very easily fixed in position compared
with the usual way.
We have described the above way in which our invention may be carried into
effect, but we wish it to be understood that we do not confine ourselves to the
arrangement described, as the same may be altered in its details without departing
from the invention, moreover our improved shades or reflectors of square or
rectangular shape may be applied to any suitable bracket pendant or lamp, and we
do not confine their use to the pendant we have described.

page_text: 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 :-
1. The improvement in gas brackets or pendants, which consists in forming at
the end of the arm or arms a small downwardly projecting bent gas pipe the
upward bend of which is fitted with a burner and does not reach as high as the
plane of the supporting arms, whereby said arms will be clear of the jets and will
not in any way obstruct the lighting of or throw a shadow on the billiard table or
other object substantially as described.
2. Mounting the shades or reflectors for gas pendants or brackets upon a bracket
or gallery such as F, supported by means of a sleeve on the arms of the gas
bracket or pendant substantially as described.
3. The general combined arrangement and construction of parts forming our
improved gas bracket and shades substantially as described.
