Improvements in Machinery or Apparatus for "Clearing” and
"Gassing" Yarns or Threads.
1. GEORGE KIRKHAM, of 37, Ashton New Road, Beswick, Manchester, in the
County of Lancaster, Mill Manager, do hereby declare the nature of this invention
to be as follows:-
5:
The first part of my invention consists in performing the process known as
"clearing" yarn or thread and the process known as "gassing" yarn or thread in
one machine instead of as heretofore performing the operations, of clearing" and
"gassing" in two separate operations and by means of distinct and separate
machines.
A further part of my invention consists in the arrangement of apparatus which
1 employ in performing my invention.
According to this part of my invention I pass each of the yarns or threads to be
cleared through the apparatus known as a yarn clearer by means of which the yarn
or thread is cleared of motes, lumps, knots or thick places. The yarn or thread
then passes around the bowls usually employed in "gassing frames" and is caused to
pass through a gas flame. The yarn or thread is afterwards wound upon a bobbin
or spool in the usual manner by means of a surface drum or roller or by any other
suitable means.
In some cases in conjunction with the said apparatus I employ a
roller covered with flannel or other suitable material for acting upon the yarn or
thread while being gassed for cleaning and imparting lustre to the yarn or thread.
This roller is caused by suitable means to revolve.
By my invention I am enabled to "clear" and "gas ".yarn at one operation and
thereby am enabled to avoid the injurious strains and numerous "handlings" to
which the yarn is subjected in the processes of "clearing" and "gassing" as
heretofore conducted.

Further by the operations of clearing" and "gassing" being performed at one

page_text: much waste and loss of time would be caused. I therefore prefer to mount the
bobbins in the manner illustrated in the accompanying drawings so that such
bobbins d may be very readily revolved by the yarn or thread being drawn
therefrom. For this purpose I provide brackets p p such as are shown in Figs. 3
and 4 which are formed with notches p' the lower surfaces of which are convex and
I mount each of the bobbins d upon a spindle 7 preferably of hardened steel which
is made in the form of a cylinder provided with conical ends and is when in use
caused to rest in the notches p' in two of the brackets p in which notches p¹ such
spindle may be revolved very readily by the unwinding of the yarn or thread
from the bobbin & mounted upon such spindle 7. The machine constructed according
to my invention may be provided with any suitable arrangement of "stop motion
by means of which on the breakage or burning through of a yarn or thread the
bobbin, spool or tube upon which such yarn or thread is being wound may be
removed from the surface drum by which yarn or thread is caused to be wound
upon such bobbin tube or spool g and the burner c from which issues the flame
employed to " gas" such yarn or thread may be moved aside to allow the said yarn
or thread to be again passed around the bowls band "pieced."
The form of the spindles which I have described is that best adapted for use
when fine yarns are to be cleared" and "gassed in a machine constructed
according to my invention but if yarns or threads which will endure greater strain
without injury are to be "cleared" or "gassed" spindles of a cylindrical form
and without conical ends or with ends of any other suitable form which may be
cheaper to make than spindles with conical ends may be employed to support the
bobbins d upon which the yarns or threads to be "cleared" and "gassed" are
wound. If the mechanism by means of which the longitudinal to and fro motion
imparted to the rail upon which are mounted the guides / be so arranged as to
cause such rail to be quickly traversed to and fro the yarns or threads "cleared"
and gassed" may be wound upon bobbins or spools without heads into the form
of what are commonly called "cheeses." If it is not desired to clean or impart
lustre to the yarns or threads being "cleared" and "gassed "the roller j may be
dispensed with.

By my invention I am enabled to "clear" and "
gas" yarn at one operation and
thereby I am enabled to avoid the injurious strains and numerous "handlings" to
which the yarn is subjected in the processes of “clearing" and "gassing" as
hitherto conducted. Further by the operations of "clearing" and "gassing
being performed at one time in one machine the cost of the "clearing" and
"gassing" is much reduced in comparison with the cost of "clearing" and "gassing
in separate operations in separate machines and the operations of "clearing" and
"gassing" when performed at one time and in one machine in accordance with my
invention are more efficient in ensuring that the yarns or threads "cleared" and
gassed shall be of uniform character and free from motes, lumps, knots or thick
places. The above described arrangement of the brackets p and spindles y to
support the bobbins, tubes or spools from which the yarns or threads to be
"cleared or "gassed" are to be unwound enables the said yarns or threads to be
unwound from such bobbins, tubes or spools without being strained and injured as
often happens whereas in "clearing machines" and "gassing machines as hitherto
constructed the yarns or threads to be "cleared" or "gassed" are drawn off at the
ends of the bobbins, spools, or tubes upon which they have previously been wound.
It is obvious that the arrangements of the details of the machines constructed
according to my invention may be considerably modified without departure from
he principles of my invention and that the yarns or threads to be cleared
and gassed "may be wound upon bobbins, spools or tubes of any suitable form.
Having now particularly described and ascertained the nature of my said inven-
ion and in what manner the same is to be performed I declare that what I
laim is
