County of York. IMPROVEMENTS, IN MACHINERY AND APPARATUS FOR GASSING,
CLEARING, 'SMOOTHING, AND FINISHING SPUN YARN AND THREAD OR OTHER
FIBROUS MATERIALS."
This Invention is designed or has for its object a considerable saving in the labor
and expense.(as compared with the process hitherto adopted) in the gassing, clearing,
smoothing, and finishing of spun yarns and threads.
I
And our improvements consist in a special construction of the "rail" or support
which carries the ordinary, friction caps or revolving,pullies around, and on which
the yarn or thread passes in its transit from the bobbins on the spindles of the
machine to the bobbin, or spool which receives it in its cleansed or finished state,
and the construction of the aforesaid "rail" is of such a nature that two or more
fires
or gas burners are employed to each "rail" at any suitable and required
distance from each other.

ALD
It has hitherto been usual and found necessary to pass yarns in the clearing
process through the machine two, three, or more times, but according to our Inven-
tion and by the use of our improved apparatus, one process is about equal to two on
the ordinary methods, thus effecting a saving in labor of about, one-half. :

JAMES HOLT and LEMUEL CLAYTON, both of Wellington Mills, Halifax, in the
County of York. "IMPROVEMENTS IN MACHINERY AND APPARATUS FOR GASSING,
CLEARING, SMOOTHING, AND FINISHING SPUN YARN AND THREAD OR OTHER
FIBROUS MATERIALS."
This Invention is designed or has for its object a considerable saving in the labor
and expense (as compared with the process hitherto adopted) in the gassing, clearing,
smoothing, and finishing of spun yarns and threads.
And our improvements consist in a special construction of the "rail" or support
which carries the ordinary friction caps or revolving pullies around, and on which
the yarn or thread passes in its transit from the bobbins on the spindles of the
machine to the bobbin or spool which receives it in its cleaned or finished state, and.
the construction of the aforesaid "rail" is of such a nature that two or more "fires" or
gas burners are employed to each "rail" at any suitable and required distance from
each other.
It has hitherto been usual and found necessary to pass yarns in the clearing
process through the machine two, three, or more times, but according to our Inven-
tion, and by the use of our improved apparatus, one process is about equal to two
on the ordinary methods, thus effecting a saving in labor of about one half.
In order that our Invention may be more fully understood we have hereunto
annexed one Sheet of Drawings illustrative of the same, and have marked it with
figures and letters of reference, the same letter referring to the corresponding part
in the various views or figures.
Fig. 1 is an elevation, part in section, of a machine for gassing, clearing, smoothing,
and finishing spun yarn and thread or other fibrous materials, with our improve-
iments attached thereto; and Fig. 2 is a plan view, shewing also gas pipes connected
thereto.
Figs: 3 and 4 are plan and edge views in detail of our improved construction of
""rail"
Fig. 5 is also detail, shewing method of connecting the vertical gas tubes with
the knocking-off lever.
Fig. 6 is side elevation; and Fig. 7, plan view of part of Fig. 5.
The machine is driven in the ordinary manner by driving shaft and speed pullies
to drive the shafts on which are the drums A, which wind the yarn on to the
bobbins B after it has passed through the gassing and clearing processes, and which
said bobbins are raised when required by the levers C, as in any ordinary gassing
franie D are the bobbins, from which the yarn to be operated upon is supplied to
the conical spools or runners e, which are mounted on suitable pins or studs fixed
in the "rail" E, which is supported on suitable fixings or brackets, and placed
intermediary or betwixt the bobbins D and B, and it will be observed on reference
to the Drawing that we construct the "rail" E with two curves or bends therein,
which allows the use of two gas jets or fires a to each rail. Although we have only
shewn two such curves or bends, and two gas jets or fires a to each rail, any con-
venient number beyond these may be employed if required, but we have shewn two
as by preference, and being sufficient to illustrate our improvement, and to those
practically acquainted with the gassing, clearing, and smoothing of yarns and
threads the advantage of one process being about equal to two on the old-plan, and
two equal to four, being able to clear and gas the same by one process over two by
the ordinary method, as will be obvious; and according to our Invention by the use
of the rail E and duplicate gas burners &; as shewn, we can accomplish-such a
saving of labor over the machines hitherto constructed, which have rendered it
necessary to pass the yarns or threads in the clearing process two, three, or more

page_text: times through the machine to obtain the necessary clearness or smoothness on the
threads.
Another important feature in the construction of the "rail" E is the application
thereto of a piece of glass c, porcelain, agate, or some such hard and smooth surface
material or substance, which we place in a recess or holder near one end of the rail,
and by the use of which not only is the yarn or thread prevented from "fraying,"
but the tension or drag is greatly diminished in its transit through the machine
before it is wound on to the bobbins B. F shews the rod or connecting piece which
duplicates the action for the gas jets or burners a; G is the lever for throwing the
same in or out of contact with the yarn as required; H are the pipes, from which
the gas is supplied to the tubes or burners a.
Having thus described the nature of our said Invention, and shewn by Drawings
how the same may be performed and carried into practice, we would have it under-
stood that what we claim as our Invention and believe to be new is,-
Firstly. The construction of the rail E, and the application of two or more gas
jets or fires to each rail, substantially in manner and for purposes as herein
described.
Secondly. The application and use of the glass c, or some such hard and smooth
substance fixed in the rail E, in manner substantially and for purposes as set forth
in the description.
In witness whereof, we, the said James Holt and Lemuel Clayton, have
hereunto set our hands and seals, this Twenty-first day of February, in the
year of our Lord One thousand eight hundred and seventy-nine.
