Year: 1864

page_text: LETTERS PATENT to Richard Tye, of Birmingham, in the County of
Warwick, Manufacturer, for the Invention of "IMPROVEMENTS IN SLIDING
GASALIERS, GAS PENDANTS, AND GAS LAMPS."
Sealed the 2nd June 1865, and dated the 5th December 1864.
PROVISIONAL SPECIFICATION left by the said Richard Tye at the
Office of the Commissioners of Patents, with his Petition, on the
5th December 1864.
I, RICHARD TYE, of Birmingham, in the County of Warwick, Manufacturer,
do hereby declare the nature of the said Invention for " IMPROVE-
IN SLIDING GASALIERS, GAS PENDANTS, AND GAS LAMPS," to be as
follows:-
My Invention consists, firstly, of the following arrangements of parts of
sliding gasaliers for the purpose of preventing the falling of the moving parts of
the said gasaliers in case of the breaking of the chains of the said gasaliers.
The interior of the slide of the gasalier is the same as the ordinary water slide,
my improvements applying to the exterior parts only of the gasalier. The
balance weights of the gasalier are made to slide on square tubes attached
to a bridge crossing the pulley frame. At the bottom of each tube is a fixed
pan or weight receiver, not connected with the outside tube of the slide, and
made of such a shape that it will miss all ornaments or parts affixed to the
outside tube. Below the weight receivers, and near the vase part of the

page_text: gasalier is a fixed canopy, soldered or screwed firmly upon the outside tube, the
said canopy carrying three wires or rods, which slide inside the square tubes
on which the balance weights work. The object of these rods is to steady the
tubes upon which the balance weights work. This part of the gasalier may
be modified in the following way, that is, by fixing a bridge on the under
part of the pulley frame, in an opposite position to that on the upper part, and by
using instead of square tubes hard drawn cased iron wires, similar to stair
rods. These wires are pushed tightly through the bottom bridge and
screwed into the top bridge, which makes them quite steady, so that they only
require the weight receivers at bottom. The water cup has three strong
round rings attached to it, through which the weights can pass without
contact. The chains are attached to the outer edge of the said rings, and
pass over the wheels inwards instead of outwards, as in the ordinary slide, and
descending close to the square tubes or wires are fastened to the weights. The
action is as follows:-When the slide is pulled down the weights travel up the
tubes or wires, and pass through the rings affixed to the water cup till they
reach the pulley frame. Should the chains break, the weights would
immediately travel down the tubes or wires and rest upon the pans or receivers
at the bottom, the sliding part of the gasalier would also fall, but the pans
being a little larger than the weights, the rings affixed to the water cup
cannot pass over them, so that the moving part of the gasalier cannot fall
lower than the weight receivers. In the arrangement described the wires or
tubes do not interfere any more with the design of the gasalier than the
pulley chain itself, as they both travel side by side, and form one line.
My Invention consists, secondly, of constructing or arranging the parts of a
safety ball valve for sliding gasaliers and gas pendants in the following
manner, by which construction or arrangement the gas. can readily be turned
off at the ceiling, and the escape of gas, on the occurrence of an accident,
thus prevented. The said ball joint consists of two hollow parts screwed
together, the upper part being screwed to an ordinary iron socket, at the
ceiling of the room. In the interior of the lower part of the ball joint and
working gas-tight therein is a half ball, connected by a tail piece to the slide
of the gasalier or pendant. A square shoulder in the middle of the top of the
half ball projects into the interior of the ball joint. In the interior of the
, upper part of the ball joint is a bucket-shaped hollow plug, working gas-tight
in the said part. In the side of the said hollow plug a hole or opening is
made, communicating with the interior of the said plug, and in one side of
the interior of the ball joint, in which the plug works, a passage or channel is
made. By turning the hollow plug in one or other direction the hole in its

page_text: side can either be made to coincide with the channel in the ball joint, or the
said hole in the plug closed by being turned from the said channel. From
the bottom of the hollow plug a pin passes, terminated by a square head
corresponding in size with the square shoulder on the top of the half ball in
the lower part of the ball joint. A perforated plate is. supported on the head
of the said pin. The upper square shoulder on the balf ball and the square
head of the pin last described, are connected by a square-coiled spring fitting
on the said parts. By this arrangement rotary motion of the half ball is
communicated to the hollow plug, and the half ball at the same time allowed
to swing freely in the fixed part of the joint. The top of the square spring
bears upon the. perforated plate described under the hollow plug. The tail
piece of the half ball is provided with a stop pin, working in the flange of the
lower part of the ball joint for limiting the motion of the said tail piece. By
turning the gasalier or pendant half round, so that the stop pin is at one side
of the opening in the flange at the bottom of the ball joint, the hole in the
hollow plug is made to coincide with the channel or passage in the upper part
of the ball joint, and gas can pass down the said passage, through the
perforated plate into the gasalier or pendant. By turning the gasalier or
pendant in the contrary direction, the hole in the hollow plug is removed from
opposite the channel in the ball-joint and the gas shut off. Ball joints of the
construction described may be readily applied to all gasaliers and pendants
now in use...
My Invention consists, thirdly, of the following arrangement of the parts of
glass holders for enabling the glass or globe of gasaliers, pendants, and gas
lamps to be readily raised from the burner för lighting the gasalier, pendant,
or gas lamp. Upon the burner a triangular piece of metal is situated, being
connected thereto by screwing or otherwise. The termination of each of the
radial arms of the triangular piece carries a fixed vertical rod or wire. On.
the inner side of the gallery or glass holder, in which the glass or globe is
supported and fixed, three projecting pieces or radial brackets are made;
through holes in these brackets the three vertical rods or wires on the
burner slide. By lifting the gallery or glass holder it slides upon the vertical
rods or wires, and exposes the burner when the gas can be lighted. After
lighting the gas, the gallery or glass holder is lowered on to the burner, and
the glass or globe made to surround the flame.. By this arrangement of the
glass holder, the holder and branch of the gasalier, or pendant, or other lamp
are prevented from being smoked and soiled in lighting the gas.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Tye, in the Great Seal Patent Office on the
5th June 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
TYE, of Birmingham, in the County of Warwick, Manufacturer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifth day of December, in the year of our
Lord One thousand eight hundred and sixty-four, in the twenty-eighth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Richard Tye, Her special licence that I, the said Richard
Tye, my executors, administrators, and assigns, or such others as I, the
said Richard Tye, my executors, administrators and assigns, should at any
time agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "Iм-
PROVEMENTS IN SLIDING GASALIERS, GAS PENDANTS, AND GAS LAMPS," upon the
condition (amongst others) that I, the said Richard Tye, my executors or
administrators, by an instrument in writing under my, or their, or one of
their hands and seals, should particularly describe and ascertain the nature
of the said Invention, and in what manner the same was to be performed,
and cause the same to be filed in the Great Seal Patent Office within
six calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Richard Tye, do hereby declare the
nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement thereof, reference being had to the Drawings hereunto annexed,
that is to say:-
My Invention consists, firstly, of the following arrangements of parts of
sliding gasaliers for the purpose of preventing the falling of the moving
parts of the said gasaliers in case of the breaking of the chains of the said
gasaliers. The interior of the slide of the gasalier is the same as the
ordinary water slide, my improvements applying to the exterior parts only
of the gasalier.
Figure 1 of the accompanying Drawings shows so much of a gasalier as
will be necessary to illustrate one method of carrying this part of my Invention

page_text: into effect. The balance weights a, a, of the gasalier are free to slide on
tubes or rods b, b, attached to a bridge c crossing the pulley frame d. At
the bottom of each tube or rod is a fixed pan or weight receiver e, not con-
nected with the outside tube of the slide, and made of such a shape that it
will miss all ornaments or parts affixed to the outside tube. Below the
weight receivers and near the vase part of the gasalier is a fixed canopy f
soldered or screwed firmly upon the outside tube, the said canopy car ry in
three wires or rods which slide inside the tubes on which the balance weights
a work. The object of these rods is to steady the tubes upon which the
balance weights work. This part of the gasalier may be modified in the
following way: That is by fixing a bridge on the under part of the pulley
frame in an opposite position to that on the upper part, and by using, instead
of square tubes, hard drawn cased iron wires similar to stair rods. These
wires are pushed tightly through the bottom bridge and screwed into the top.
bridge, which makes them guide steady so that they only require the weight
receivers at bottom. The water cup g has strong round rings attached to it
through which the weights can pass without contact. The chains are attached
to the outer edge of the said rings or to the water cup, and pass over the
wheels inwards or outwards, as in the ordinary slide, and descending close to
the tubes or wires are fastened to the weights. The action is as follows:---
When the slide is pulled down. the weights travel up the tubes or wires till
they reach the pulley frame. Should the chains break, the weights would
immediately travel down the tubes or wires and rest upon the pans or
receivers at the bottom; the sliding part of the gasalier would also fall, but
the pans being a little larger than the weights, the rings affixed to the water
cup cannot pass over them, so that the moving part of the gasalier cannot
fall lower than the weight receivers. In the arrangement described, the
wires or tubes do not interfere any more, with the design of the gasalier
than the pulley chain itself as they both travel side by side and form one
line.
Figures 2 and 3 are views of two modifications of the arrangements just
described, similar letters of reference referring to like parts.
My Invention consists, secondly, of constructing or arranging the parts of
a safety ball valve for sliding gasaliers and gas pendants, as shewn in section
at Figures 4 and 5, by which construction or arrangement the gas can readily
be turned off at the ceiling, and the escape of gas on the occurrence of an
accident thus prevented. The said ball joint consists of two hollow parts
a, b, screwed together, the upper part being screwed to an ordinary socket at
the ceiling of the room. In the interior of the lower part of the ball joint

page_text: and working gas-tight therein, is a half ball connected by a tail piece d to
the slide of the gasalier or pendant; a square shoulder e in the middle of the
top of the half ball projects into the interior of the ball joint. In the interior
of the upper part of the ball joint is a bucket-shaped hollow plug f working
gas-tight in the said part. In the side of the said hollow plug a hole or
opening 9 is made communicating with the interior of the said plug, and in
one side of the interior of the ball joint in which the plug works a passage or
channel is made. By turning the hollow plug in one or other direction, the
hole in its side can either, be made to coincide with the channel in the ball
joint or the said hole in the plug closed by being turned from the said channel.
From the, bottom of the hollow plug a pin h passes, terminated by a square
head corresponding in size with the square shoulder on the top of the half
ball in the lower part of the ball joint. A perforated plate is supported on
the head of the said pin. The upper square shoulder on the half ball, and the
square head of the pin last described, are connected by a square coiled spring i,
Figure 5, fitting on the said parts. By this arrangement rotary motion of the
half ball is communicated to the hollow plug, and the half ball at the same
time allowed to swing freely in the fixed part of the joint. The top of the
square spring bears upon the perforated plate described under the hollow
plug... The tail piece of the half ball is provided with a stop pink working in
the flange of the lower part of the ball joint, for limiting the motion of the
said tail piece. By turning the gasalier or pendant half round so that the
stop pin is at one side of the opening in the flange at the bottom of the ball
joint, the hole in the hollow plug is made to coincide with the channel
or passage in the upper part of the ball joint, and gas can pass down the
said passage through the perforated plate into the gasalier or pendant. By
turning the gasalier or pendant in the contrary direction the hole in the
hollow plug is removed from opposite the channel in the ball joint, and the
gas shut off.
Figures 6 and 7 are views of another arrangement for accomplishing the
same purpose, but where I dispense with the hollow plug f I place a disc of
metal m over the plate n, and loose thereon; the pin h passes through the
plate n and screws into a lump formed on the disc. Apertures are made in
the disc and plate, which when corresponding (and this is done by turning
the gasalier or pendant as before described), allow free passage to the gas, but
at other times the apertures in the plate n are closed by the disc so that gas
cannot pass. Ball joints of the construction described may be readily applied
to all gasaliers and pendants now in use. Sometimes I altogether dispense
with the spring i.

page_text: My Invention consists, thirdly, of the following arrangement of the parts of:
glass holders for enabling the glass or globe of gasaliers, pendants, and gas
lamps to be readily raised from the burner for lighting the gasalier, pendant,
or gas lamp.
.
Figure 8 is a perspective view of this arrangement shown applied to a gas
burner. Upon the burner a I place a metal support b, by preference
triangular as shown, it is connected thereto by screwing or otherwise. The
termination of each of the radial arms of the triangular piece or support 6
carries a fixed vertical rod or wire c. On the inner side of the gallery or
glass holder d in which the glass or globe e is supported and fixed, three pro-
jecting pieces or radial brackets f, f. f, are made; through holes in these
brackets the three vertical rods or wires c, c, c, on the burner slide. By lifting
the gallery or glass holder d it slides upon the vertical rods or wires c, c, c,
and exposes the burner, as shown, when the gas can be lighted; after lighting
the gas, the gallery or glass holder is lowered on to the burner, when the
glass or globe surrounds the flame. By this arrangement of the glass holder,
the holder and branch of the gasalier or pendant or other lamp are prevented
from being smoked and soiled in lighting the gas. Although I prefer to use
a triangular bracket with three vertical rods or bars, yet I do not limit
myself to that number as it is evident that two, four, or more might be used
without departing from my Invention; and, further, I would have it under-
stood that this arrangement for preventing the glass being smoked, although
particularly described herein as applied to gas burners, is equally applicable to
other burners and lamps without departing from this my Invention.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim as my improve-
ments in sliding gasaliers, gas pendants, and gas lamps,―
First, the construction, arrangement, and method of action of the sliding
parts of gasaliers together with any mere modifications thereof, whereby the
moving parts are prevented from falling in case the chains break, substantially
in manner herein-before described and illustrated at Figures 1, 2, and 3 of
the accompanying Drawings.
Second, the construction and arrangement of ball valves for sliding
gasaliers and gas pendants whereby the gas can be turned off when desired,
substantially as herein-before described and illustrated at Figures 4, 5, 6,
and 7 of the accompanying Drawings.
Third, the application to glass holders, pendants, and lamps of an apparatus
whereby the glass or globe can be raised above the burner to light the same,

page_text: the said apparatus being constructed and acting substantially in manner
herein-before described and illustrated at Figure 8 of the accompanying
Drawings.
In witness whereof, I, the said Richard Tye, have hereunto set my'
hand and seal, this Thirty-first day of May, One thousand eight
hundred and sixty-five.
RICHARD TYE. (LS.)
