IMPROVEMENTS IN GASSING FRAMES to be as follows:-
Year: 1884

page_text: We JOHN THOMAS FLETCHER and THOMAS QUINN both of the Carrington Mills
Company, New Bridge Lane, Stockport in the County of Chester, Managers, do
hereby declare the nature of the said invention for "IMPROVEMENTS IN GASSING
FRAMES to be as follows:-
"
Our invention relates to the apparatus employed in the gassing of yarns and
consists chiefly in a novel method of applying the gas flame so as to increase its
efficiency and to effect an economy in the consumption of gas. In the ordinary
gassing frame the burner is arranged horizontally above the frame and the yarn
passes across a perpendicular flame that portion of the flame which is above the
yarn being entirely wasted. As a consequence the yarn requires to be passed and
re-passed several times through the flame before it is sufficiently
"gassed."
According to our invention we arrange a burner perpendicularly in front of the
frame from which burner the gas issues through several small perforations the
flame being encased in a split tube or chimney which draws upwards and elongates
the flame. As the yarn passes upwards to the guide pullies it is led through
the said tube or chimney containing the elongated flame and is thus kept a
comparatively long time in contact with the said flame whereby the full length
of the flame is utilised and the yarn is sufficiently "gassed" without requiring to
be again passed through the flame. We may pass one two three or more yarns
through the flame at the same time the several bobbins receiving the yarns being
arranged around and deriving motion from a common central driving pulley or
drum. We do not confine ourselves to the position of the burner in front of the
frame or to the exact perpendicularity of the burner the important features being
the upward or downward passage of the yarn through the flame and the passing
of two or more distinct yarns through one flame.

Company New Bridge Lane Stockport in the County of Chester, Managers, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN GASSING
FRAMES and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement and accompanying
drawings:
"
Our Invention relates to the apparatus employed in the gassing of yarns and
consists chiefly in a novel method of applying the gas flame so as to increase its
efficiency and to effect an economy in the consumption of gas. In the ordinary
gassing frame the burner is arranged horizontally above the frame and the yarn
passes across a perpendicular Hame that portion of the fame which is above the
yarn being entirely wasted. As a consequence the yarn requires to be passed
and re-passed several times through the flame before it is sufficiently "gassed."
According to our invention we employ a burner from which the gas issues through
small perforations the flame being encased in a-vertical-split tube or chimney
I which draws upwards and elongates the flame As the yarn passes upwards to the
guide pullies it is led through the said tube or chimney containing the elongated
Hame and is thus kept a comparatively long time in contact with the said flame
whereby the full length of the flame is utilised and the yarn is sufficiently "gassed,"
without requiring to be again passed through the flame. We may pass one two
three or more yarns through the flame at the same time the several bobbins
receiving the yarns being arranged around and deriving motion from a common
central driving pulley or drum.
To render the description of our Invention more clear we will refer to a sheet
of drawings which we have attached hereto and which represents the parts of a
gassing frame to which our Invention more immediately relates. In the said
drawings Fig 1. is a cross sectional view about half the full size. Fig: 2 is a
vertical section and Fig: 3 a plan of our improved burner drawn about the full size.
In Fig 1 a is the burner which is screwed or secured to the outer end of a tubular
arm b. which is connected with a gas pipe c. which supplies a number of burners
as is usual. In the example the pipe c is suspended by means of rods from the
front rail f. of the frame one of these rods being indicated by g. When so arranged
the burners project from the front of the frame instead of being above the top of
the frame the indicated arrangement being the one we prefer although we do not
confine ourselves to it. On referring to Figs: 2 and it will be seen that the
burner has a tubular shell a. which is split or open on one side that is to say on
the front side or the side which is presented to the operator. The tubular shank al
leads into a cavity a³ which is drilled in an enlarged part of the shell and is closed
by means of a removable screw plug as is usual. A number of small holes are
drilled through the shell into this cavity and through these holes the gas or
mixture of gases, issues and when lighted forms a flame which is extended upward
as indicated the shield acting as a chimney to draw the flame and also to steady
the same by shielding it from draughts whereby a hot flame of greatly increased
length is obtained. The yarn to be gassed is drawn through this flame in a vertical
or nearly vertical direction or in the general direction of the length of the flame
so as to obtain the maximum result from the flame. In the example two yarns
are supposed to be passed through each flame. These yarns are drawn from two
bobbins h h and passing over a rod i are led in a vertical direction over pulleys k.
and 7. passing in a vertical direction through the flame on their way. The said

page_text: pulleys are adjustable in position upon a frame m by which they are carried so
that the yarns can be guided to move in the direction which will give the best
practical results. In order that the yarns shall be separated to a suitable degree
as they pass through the flame one of the two pullies k. and / or each of them is
formed with two grooves each yarn lying in a separate groove. In place of the
indicated arrangement any suitable means may be employed for guiding or leading
the yarn through the flame. Each yarn passes from the pulley to a bobbin n
which is carried by a lever o. which is so supported as that the coiled yarn tends
to continue in contact with the periphery of a revolving pulley or drum p. the
effect being that the bobbins are caused to revolve and to draw forward the yarn
and at the same time to wind the same. We may draw more than two yarns or
may only draw a single yarn through one flame. The parts might be arranged for
the yarn to pass downward through the flame instead of upward. We do not
confine ourselves to the exact form of burner so long as it is formed or provided
with a shield guard or chimney which induces an upward elongation of the flame
the yarn being passed upward or downward in such a manner as to be exposed
to the action of the flame for a lengthened period in contradistinction to the
ordinary practice of drawing the yarn across the flame.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:
1. The gas burner constructed and used substantially as and for the purpose
set forth and indicated hereinbefore and in and by the accompanying drawings.
2. A gas burner formed or provided with an upwardly extending shield or
chimney whereby is produced an elongated flame through which is or are drawn
the yarn or the ends of yarn in an upward or downward direction substantially as
set forth.
3. Arranging the burners of yarn gassing frames in front of the frames and
passing the yarns upward or downward through the flames in the general direction
of the lengths of the flames substantially as set forth.
4. The combination of parts constructed arranged and acting substantially as and
for the purposes set forth and indicated.
5. Drawing two or more yarns simultaneously through a gas flame elongated
by means of a shield or chimney and winding the yarns by the driving contact of
one drum or pulley substantially as set forth and indicated.
