Makers, do hereby declare the nature of this invention to be as follows:-
Our invention relates to machinery or apparatus for gassing yarns or threads.
The object of our invention is, in part, to simplify and improve the construction
of the means employed in machinery or apparatus of the said kind for the purpose
of moving the bobbins, spools or tubes on which the yarns or threads are wound
after being gassed in such machinery or apparatus into and out of position to
receive motion from the drums or surfaces by which they are driven and holding
such bobbins, spools or tubes in and out of position to be driven by such drums or
surfaces and moving the burners employed and holding them in and out of the
position in which they require to be placed in order that the flames therefrom may
act upon the yarns or threads being operated upon and, in part, to render it easier
and more convenient than it has been with the means hitherto employed for the said
purposes to move the bobbins, spools or tubes on which the yarns or threads are to
be wound into and out of position for being driven and secure them in and out of
position for being driven as may be desirable from time to time.
According to our invention we provide in conjunction with each bobbin, spool or
tube upon which yarn or thread is to be wound in a gassing frame, a lever or
handle which we make and arrange so that it may be capable of being turned about
an axis and also be capable of receiving a movement of translation in relation to
the axis about which it may be turned so that a projection or part upon such handle
or lever may be placed in and out of engagement with a part of or upon the
support on or in which it is mounted. We connect the said handle or lever in any
suitable manner to the burner or burners the flame or flames from which is or are
employed to act upon the yarn or thread or yarns or threads passing to the said
bobbin spool or tube, so that the burner or burners may be moved by means of such
handle or lever. We also provide the said handle or lever with a part or surface
capable of being made to bear against and move the lever or frame carrying the
said bobbin, spool or tube and so move such bobbin, spool or tube, out of the
position in which it is driven by the drum or surface employed to impart motion
thereto and we also provide the said handle or lever with a notch or projection or
other equivalent device capable of passing into engagement with any suitable part
of or upon the lever cr frame upon or in which the said bobbin, spool or tube is
mounted so that such handle or lever serves as a means of moving the said bobbin,
spool or tube out of the position in which it is driven and also when placed in
engagement with the part or support on or in which it is mounted and in engagement
with the said lever or frame serves to hold the said bobbin, spool or tube out of

Improvements in Machinery or Apparatus for Gassing Yarns
or Threads.
We, WILLIAM THOMAS STUBBS and JOSEPH HETHERINGTON STUBBS, both
of Mill Street Works, Ancoats, Manchester, in the County of Lancaster, Machine
Makers, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
Our invention relates to machinery or apparatus for gassing yarns or threads..
The object of our invention, is, in part, to simplify and improve the construction
of the means employed in machinery or apparatus of the said kind for the purpose
of moving the bobbins, spools or tubes on which the yarns or threads are wound
after being gassed in such machinery or apparatus into and out of position to
receive motion from the drums or surfaces by which they are driven and holding
such bobbins, spools or tubes in and out of position to be driven by such drums or
surfaces, and moving the burners employed and holding them in and out of the
position in which they require to be placed in order that the flames therefrom may
act upon the yarns or threads being operated upon, and in part, to render it easier
and more convenient than it has been with the means hitherto employed for the
said purposes to move the bobbins, spools or tubes on which the yarns or threads
are to be wound into and out of position for being driven and secure them in and
out of position for being driven as may be desirable from time to time.
According to our invention, we provide in conjunction with each bobbin, spool
or tube upon which yarn or thread is to be wound in a gassing frame a lever or
handle which we make and arrange so that it may be capable of being turne I
about an axis and also be capable of receiving a movement of translation in relation
to the axis about which it may be turned so that a projection or part upon such
handle or lever may be placed in and out of engagement with a part of or upon
the support on or in which it is mounted. We connect the said handle or lever in
any suitable manuer to the burner or burners, the flame or flames from which is or
are employed to act upon the yarn or thread or yarns or threa Is passing to the
said bobbin, spool or tube, so that the burner or burners may be moved by means
of such handle or lever. We also provide the said handle or lever with a part or
surface capable of being made to bear against and move the lever or frame carrying
the said bobbin, spool or tube, and so move such bobbin, spool or tube out of the
position in which it is driven by the drum or surface employed to impart motion
thereto and we also provide the said handle or lever with a notch or projection
or other equivalent device capable of passing into engagement with any
suitable part of or upon the lever or frame upon or in which the said bobbin, spool
or tube is mounte1, so that such han 11 ur lever serves as a means of moving the
said bobbin, spool or tube out of the position in which it is driven, and also when
placed in engagement with the part or support on or in which it is mounted and in
engagement with the sail lover or framerves to hold the sail hubhin, spuul or
tube out of contact with the drum rurfurt provide to hapart motion pret.
A weight or weights or other suitable means acting upon the said lever or frame

page_text: any suitable manner may be employed to press the bobbin, spool or tube towards
or against the drum or surface by which motion is imparted to such bobbin, spool
or tube, and the handle or lever aforesaid may be used as a means of controlling
the rate at which the said bobbin, spool or tube is allowed to move towards the said
drum or surface after being removed therefrom.
Our invention is particularly applicable to what are known as quick traverse
gassing frames in which the yarns or threads gassed are wound on to bobbins or
spools which are without heads, but our invention is applicable to other kinds of
machinery or apparatus for gassing yarns or threads.
In the accompanying drawings,
Fig. 1 is a front elevation and Fig. 2 a transverse section with certain parts in
side elevation, showing so much of a quick traverse gassing frame, as is requisite
for the illustration of our invention.
Fig. 3 is a side elevation and Fig. 4 a front elevation of one part of that which
is shown in Figs. 1 and 2.
Fig. 5 is a side elevation and Fig. 6 a front elevation of another part of that
which is shown in Figs. 1 and 2.
Fig. 7 is a side elevation and Fig. 8 a front elevation of another part of that
which is shown in Figs. 1 and 2 and
Fig. 9 is a side elevation and Fig. 10 a front elevation of another part of that
which is shown in Figs. 1 and 2.
Figs. 5, 6, 7, 8, 9 and 10 are drawn upon a scale one-third larger than Figs. 3
and 4.
The same letters of reference are applied to corresponding parts throughout the
whole series of figures.
In Figs. 1 and 2 of the accompanying drawings, (a) is one of the revolving drums
employed in the quick traverse gassing machine to impart motion to the bobbins
or spools upon which the yarns or threads gassed in such machine are to be wound.
One of the said bobbins or spools is indicated at (b) in Figs. 1 and 2 of the
accompanying drawings as being mounted upon a stud (c) securel in a frame or
lever (d) capable of being oscillated upon a rod (e) extending lengthwise of the
machine and supported in brackets (f) secured to a rail (g) extending lengthwise
of the machine, of which brackets (f) only one is indicated in the accompanying
drawings. In Figs. 7 and 8 the frame or lever (d) is shown detached, with the
stud (c) secured in it. In conjunction with the frame or lever (d) is provided a
collar () which is embraced between jaws formed upon such frame or lever (h)
and is secured by means of a set screw upon the rod (e) and so prevents the said
frame or lever (d) from being moved lengthwise of the said rod (e). The revolving
drums (a) are mounted in the ordinary manner upon a shaft (i) extending
lengthwise of the machine and supported and receiving rotary motion in any
suitable manner. (j) is the lever or handle which is provided in conjunction with the
bobbin or spool (b) in accordance with our invention, a similar lever or handle (j) being
provided in conjunction with each of the other similar bobbins or spools employed in
the machine of which part is shown in the accompanying drawings. The lever or
handle (j), which is shown detached in Figs. 3 and 4, is capable of being turned about
the axis of a rod (k) extending lengthwise of the machine and is formed with a slot (j')
so as to be capable of receiving a movement of translation in relation to the axis of
the rod (k) and is provided with a projection (1) which as will be hereinafter
further described may be placed in and out of engagement with a hook or pro-
jection (m³) formed upon a bracket (m) secured by means of a set-screw upon the
rud (k) and shown detached in Fig. 5 and 6. Upon the rod () is mounted an
arm (n) which is capable of being oscillated thereon and is formed with a slot (n')
into which projects a stud or projecting part (3) formed on the lever or handle (j)
and causing the arm (n) to move when the lever or handle () is turned upon the
rod (k). The arm (n), which is shown detached in Figs. 9 and 10, is formed with
a slot (n) into which projects an arm (p) secured upon the stem of the gas-
burner (p) which is supported by the pipe (9) extending lengthwise of the machine

page_text: and is similar and arranged similarly to the gas-burners ordinarily employed in
machinery for gassing yarns or threads. The brackets (m) besides serving to
carry the hook or projection (m³) embraces the lever or handle (7) and arm (n)
and so prevents such lever or handle (7) and arm (n) from being moved lengthwise
of the rod (k). The lever or handle () which is formed with a part () which
constitutes a finger-piece to enable the said handle or lever (i) to be more easily
moved, and is formed with a part (6) which when the part (4) of such lever or
handle (i) is moved upwards bears against a hooked projection (d¹) upon the frame
or lever (d) and being shaped so as to act as a cam moves such frame or lever (d)
in the direction indicated by the arrow (A) and moves the bobbin or spool (b)
away from the drum (a). The hooked projection (d) embracing the lever or
handle () as the part (1) thereof is raised, acts as a guide both to such lever or
handle () and the frame or lever (d) in their movement. The lever or handle (j)
is provided with a part (78) which is so formed that when such lever or handle ()
is moved by the part (1) thereof being raised and by such lever or handle (1) being
made to receive such a movement of translation in relation to the rod (k) as will
bring the projection (2) upon such lever or handle (j) into a position in which
it will be supported by the projecting part (m³) upon the bracket (m), the said
part () will bear against the hooked projection (d) and hold the frame or
lever (d) in the position into which it is moved by the said movement of the
lever or handle (1), in opposition to the pull of the weight (r) which tends to keep
the surface of the bobbin or spool (b) or the yarn or thread wound thereon in
contact with the drum (a) and is connected to the said frame or lever (d) by
means of a chain (s) passed over a pulley (t) capable of being made to revolve
upon the rod (u) extending lengthwise of the machine and supported by the
bracket () and the other similar brackets employed in such machine. The frame
cr lever (d) is provided with holes by means of any one of which the chain (s)
may be connected to such frame or lever (d) so that the pull exerted upon the
frame or lever (d) by the weight (r) may be adjusted.
In Figs. 1 and 2 of the accompanying drawings (r) (v) are the bowls around
which the yarn or thread to be gassed by means of the flame from the burner (p),
and to be wound upon the hobbin or spool (b) is passed, (w) is a guide-rod and
(c) is the traversing guide which serves to guide the said yarn or thread on to the
bobbin or spool (4) and is mounted upon à traverse-rail (l) As the bowls (r),
guide-rod (w), traverse-guide (c) and traverse-rail (a) form no part of our present
inver tion, and may be arranged in any usual or suitable manner, we will not refer
further to them except in so far as may be requisite in the description of other
parts shown in the accompanying drawings. In the accompanying drawings it is
indicated that the lever or handle (j) is so formed that in being moved in
accordance with the requirements of its use it shall not be brought into contact
with the traversi-rail (.).
In Figs. 1 and 2 of the accompanying drawings the frame or lever (d), weight ()
and chain (s), the lever or handle (), the arm (n) and the arm (') are indicated
in full lines in the position which they occupy while the yarn or thread passing
around the bowls (r) and indicated in Fig. 2 by the lines fornied of alternate long
and short dots is being gassed and wound upon the bobbin or spool (6) and when
the winding of yarn or thread on such bobbin or spool has continued for a little
time and except for the gradual change in the position of the bobbin
spool (b), rane or lever (d), chain (s) and weight (r) due to the increase
in the thickness of the yarn or thread wound upon the bobbin or spool (b) the
said parts will remain in substantially the same position until the winding upon
the said bobbin or spool (6) of the quantity of yarn or thread required to he
wound thereon has been completed.
or
When the windling upon the bobbin or spoul (6) of the quantity of yarn or thread
required to be wound thereon has been completed or at any time when on account
of the breakage or burning through or terinination of the yard or thread being
operated upon or for any other reason is desirable that the bobbin or spool (b) or

page_text: the surface of the yarn or thread wound thereon, shall be removed from the
drum (a), the attendant in charge of the machine lifting the part (*) of the lever
or handle (1) causes the part () thereof to bear against the hooked projection (¹)
upon the frame or lever (d) and turn such frame or lever (d) in the direction
indicated by the arrow (A) in opposition to the pull exerted upon such frame or
lever (d) by the weight (r) until such frame or lever (d) is moved approximately
into the position in which it is indicated by the dotted lines in Fig. 2 and then the
said attendant raising the said part (*) of the lever or handle (j) somewhat further
moves such lever or handle (j) upon the rod (k) approximately in the direction
indicated by the arrow (B) and so causes the projection (2) upon the said lever
or handle () to be brought above the projecting part (m²) upon the bracket (m)
and then allows such projection (2) to rest upon the said projecting part (m') and
so hold the said lever or handle (j) in the position in which it is indicated by
dotted lines in Fig. 2. The movement and holding of the lever or handle (j) into
and in the position in which it is indicated by dotted lines in Fig. 2 will cause or
allow the arm (n) also to be moved into the position in which it is indicated by
dotted lines in Fig. 2, and so allow the burner (p) and arm (p¹) to move into the
position in which they are indicated in dotted lines in Fig. 1 so that the burner (p)
will no longer be beneath the yarn or thread, if there be any, remaining around
the bowls (). The lever or handle (1) is allowed to remain held in the position
in which it is indicated by dotted lines in Fig. 2 until an empty bobbin or spool (b)
has been placed upon the stud (c) in substitution for the filled one or the yarn
or thread broken or burned through has been pieced or another new yarn or
thread has been pieced or united to the one which has terminated and until all
preparations for the continuation of the gassing of yarns or threads and the winding
of yarn or thread upon the hobbin or spool carried by the frame or lever (d)
have been made, and then the part (*) of the lever or handle (i) being first
raised to disengage the projection (2) on such lever or handle (j) from the
projecting part (m) upon the bracket (m) the said lever or handle (j) is moved
upon the rod (k) in a direction approximately opposite to that indicated by the
arrow (B) and the part (*) of the said lever or handle (j) is gradually lowered
into or approximately into the position in which it is indicated in full lines in
Figs. 1 and 2 of the accompanying drawings so as to allow the weight (r) to
move the frame or lever (d) and thereby bring the bobbin or spool carried thereby
or the surface of the yarn or thread wound upon such bobbin or spool into
contact with the drum (a) and so as to regulate the speed at which the said
weight (r) is allowed to so move the said frame or lever (d). As the lever or
handle () is allowed to move into or approximately into the position in which it
is indicated by full lines in Figs. 1 and 2 of the accompanying drawings the
arm (n) will be raised into or approximately into the position in which it is
indicated by full lines in the said figures and be caused to act upon the arm (p')
and move the burner (p) back into the position in which it is indicated by full
lines in the accompanying drawings so that it shall be beneath the yarns or threads
passing around the bowls (v). When the lever or handle (j) has been allowed to
pass into or approximately into the position in which it is indicated by full lines
in the accompanying drawings the gassing of yarn or thread and the winding of
gassed yarn or thread on to the bobbin or tube (6) carried by the frame or lever (d)
will continue until again interrupted by the raising of the part (*) of the lever or
handle () or in some other way.
The lever or handle (j) thus enables the attendant in charge of the machine to
effect or control by the use of one hand only all the movements of the bobbin or
spool carried by the frame or lever (d) towards and away from the drum (a) which
are requisite to the securing or locking of the frame or lever (d) in position to
hold the bobbin or spool carried thereby away from the drum (a) and the subse-
quent release of such frame or lever (d) as well as the movements of the burner (p)
into and out of position beneath the yarns or threads to be gassel, and thus such
lever or bandle (j) enables the said operations to be effected more easily and

page_text: conveniently than is possible with the means hitherto employed. The lever or
handle () and the parts above described as being employed in conjunction there-
with are also simple and compact in construction and arrangement and readily
placed adjusted and secured in position.
Although we have in the accompanying drawings only shown the parts employed
in conjunction with one bobbin or spool it is obvious that in conjunction with each
of the several bobbins or spools which are intended to be simultaneously placed in
position in a gassing frame to which our invention is to be applied, there will be
provided a set of parts consisting in a frame or lever (d) and weight (r), lever or
handle () bracket (m) arm (n), burner (p), drum (a) and traverse-guide (a) and
that the rods (e) (k) (u), rail (g), axle (t) and traverse-bar (a) may extend past
and be employed in conjunction with any number of such sets of parts, or two or
more rods (e) (k) (u), axles (i) and traverse-bars (¹) may be provided as may be
requisite or desirable.
The preceding description of the manner in which our invention may be applied
to what are known as quick traverse gassing frames will also serve without further
explanation to render the manner in which our invention may be applied to other
kinds of machinery or apparatus for gassing yarns or threads and the advantages
to be obtained by the application of our invention to such machines obvious to
persons conversant with machines of such kinds.
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 :-
In a machine or apparatus for gassing yarns or threads, the combination with
each of the frames or levers employed to carry the bobbins, spools or tubes on
which the yarns or threads operated upon are to be wound of a lever or handle
such as () constructed, arranged, employed and operating for the purposes and
substantially in the manner herein before described in reference to and illustrated
by the accompanying drawings.
