Office of the Commissioners of Patents, with his Petition, on the

I, FRANCIS JOSEPH ROWLEY, of Saint John Street, in the Parish of Saint
Sepulchre and County of Middlesex, Gas Fitter, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN GAS PENDANTS, GASALIERS, AND
GAS BRACKETS," to be as follows:-
The first object of this Invention is to permit, intercept, and regulate the
flow of
gas to the burners of pendants. For this purpose I fit at the top part
of the pendant a hollow valve, plug, or. thimble, which I prefer to make
conical, and which works in a seat or socket in which is or are one or more
orifices, and a corresponding orifice or orifices is or are made in the valve or
plug; through these orifices gas is admitted to the, body of or passage through
the pendant when the valve or plug is turned in such manner as to bring its
orifices opposite those in the seat or socket so as to open them, and the gas
will be shut off when the plug or valve is turned so as to close the orifices in
the seat or socket. The valve or plug is worked or turned by a rod or stem

page_text: which passes down through the pendant, and is actuated by a key or other
turning contrivance applied at its lower end, which end may be concealed by
a knob on the pendant made of a material which is a bad or non-conductor of
heat, and having an aperture in it through which the rod is attained. To
prevent escape of gas the rod may work in a stuffing box or packing. Instead
of constructing the valve or plug to turn it may be raised and depressed by
the rod by means of a screw or otherwise, so as to open and close the orifices
in the seat or socket. Instead of the gas flowing through the plug or valve
into the body of or passage through the pendant and thence to the burners it
may be supplied to and flow through the valve seat into the valve or plug,
and thence to the burners through the rod, which is made hollow for the
purpose. When a cup-and-ball joint is used the valve or plug may work in
the ball, in the sides of which, or in a seat fitted in it, are orifices for the flow
of gas through the pendant or through the rod. Instead of turning the valve
or plug it may be stationary, or it may form a stationary head or thimble, and
the pendant or outer tube may be turned, or raised and lowered, so as to open
and close the orifices and thus admit and exclude gas which may pass through
the body of the pendant or through a hollow central rod or pipe. The pendant
may be turned by a knob or handle at bottom formed of a material which is
a bad conductor or non-conductor of heat. The improvements in pendants
are applicable to gasaliers.
The chief object of the improvements in brackets is to obtain strength,
convenience of adjustment, and compactness. I fit a check plate or a false
plate (also acting as a washer) in a back plate, through which plates the
inner or back end of the bracket passes. I construct an improved bracket
double, that is to say, it consists of two arms, limbs, or portions connected at
their inner or back ends by swivel or swing joints with the back and check
plates, and connected at their outer or front ends by a double swivel or swing
joint with an outer or front arm or portion of the bracket; or there may be
two sets of back arms or limbs.connected..by swivel or swing joints. A stay
may unite and strengthen the joints. A single bracket may be connected with
the back and check plates by a swivel or swing joint. These arrangements
of brackets may be applied as pendants or gasaliers by suspending or disposing
them vertically, the back' plate being here the ceiling plate; one or more
transverse arms or pipes may be added. At the joints are pulleys over which
cords or chains pass; by working these the angle or position of the parts of
the pendant may be adjusted or altered, or they may be folded out of the
WOV

page_text: An improved bracket, pendant, or gasalier, capable of being lengthened
and shortened, may be constructed by causing one or more of the limbs or
portions of the same to slide telescopically in either direction in another or
others of the limbs or portions through stuffing boxes or packings.
