Year: 1880

page_text: LETTERS PATENT to William Thomas Stubbs, of Manchester, in the County
of Lancaster, Machine Maker, and John Corrigan, of the same Place, Manager,
for an Invention of IMPROVEMENTS IN MACHINERY OR APPARATUS FOR
"
GASSING YARNS OR THREADS."
PROVISIONAL SPECIFICATION left by the said William Thomas Stubbs
and John Corrigan at the Ottice of the Commissioners of Patents on the
2nd October 1880.
WILLIAM THOMAS STUBBS, of Manchester, in the County of Lancaster, Machine
Maker, and JOHN CORRIGAN, of the same Place, Manager. "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR GASSING YARNS OR THREADS."
Our improvements relate to machinery or apparatus for gassing yarns or threads,
and consist, firstly, in the use of one row of drums, by which the yarn or thread is
wound upon the bobbins after being gassed or singed, each of such drums acting
upon two or more bobbins for winding the yarn thereon.
The second part of our Invention relates to an arrangement whereby we are
enabled to place the bobbin upon which the yarn is wound after being gassed or
singed in or out of contact with the winding-on drum, and simultaneously operate
upon the gas flame or burner by which the yarn is gassed or singed, causing the
said flame to act or cease to act upon the yarn or thread by the drawing out or
pushing in of one rod or lever. We accomplish this in the following manner :-
The bobbin upon which the yarn is wound, after being gassed or singed, is
mounted in a frame or cradle turning upon a pin carried by a bracket, the said
bracket being attached to the framework of the machine.
The before named cradle carrying the bobbin is drawn towards the winding on
drum by means of a weight. The previously named lever has a slot formed
therein, such slot embracing a pin projecting from the cradle. When the aforesaid
lever is thrust inwards, or drawn outwards, it rocks the cradle upon the previously
mentioned pin carried by the bracket, thereby placing the bobbin in contact with,
or withdrawing it from, the winding on drum. The previously mentioned rod or
lever has a projecting catch formed upon it, which, upon being placed in contact
with the side of a bracket attached to the frame of the machine and through which

page_text: it passes, keeps the bobbin out of contact with the winding on drum, but when the
said bobbin is in contact with the winding-on drum, and as it increases in diameter
by the yarn or threads being wound thereon, the cradle will be turned upon its
supporting pin, the slot in the before named rod or lever allowing such movement
to take place.
The side of the bracket through which the before named rod or lever passes we
form as an incline, such incline ensuring the rod or lever taking its true position.
Upon the before named rod or lever we form an inclined part, which, coming in
contact with the sides of the previously named bracket by which the rod or lever
is supported, causes the said rod or lever to move sideways, such movement acting
upon the gas pipe or burner.by means of a slot forined in the lever aforesaid
through which the said burner passes. The said burner is thereby removed from
or drawn into position for gassing or singeing the yarn or thread.
The third part of our improvements refer to the brackets used for supporting the
guide pullies or bowles used in gassing frames, around which the yarn passes while
being gassed or singed, and consists in using a bracket formed with two projecting
arms which carry the two rollers or bowles aforesaid.
Our Invention relates, fourthly, to a method of mounting the pullies or bowles
aforesaid, and consists in mounting them upon bushes turning on studs or pins.
In the said bushes we form apertures for oiling or cleaning, such apertures
being protected from dirt by the aforesaid pullies being placed upon the said
bushes.
Fifthly, we form a projecting flange or rim upon the outer edge of such pullies or
bowles aforesaid to prevent the yarn or thread from running off the same, the
running off at the other edge of such pullies being prevented by the guides formed
upon the brackets used for supporting the studs upon which the aforesaid bowles
rotate.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said William Thomas Stubbs and John Corrigan in the Great Seal
Patent Office on the 2nd April 1881.
WILLIAM THOMAS STUBBS, of Manchester, in the County of Lancaster, Machine
Maker, and JOHN CORRIGAN, of the same Place, Manager. "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR GASSING YARNS OR THREADS."
Our improvements relate, firstly, to the use of one row of drums by which the
yarn or thread is wound upon the bobbins after being gassed or singed, each of
such drums acting upon two or more bobbins for winding the yarn thereon.
Fig. 1 of the Drawings hereunto annexed is an end elevation, and Fig. 2 a
side elevation of a gassing frame combining our several improvements, certain
parts being omitted to avoid confusion. At 1 is the end framework of the machine
(shown by dotted lines) carrying a pedestal 2, supporting a shaft 3 furnished
with fast and loose pullies 4, 5, by the former of which it is driven. The shaft 3
extends from end to end of the gassing frame, and at intervals has pullies or
drums 6 mounted thereon, one only being shewn. At 7, 7*, are rails extending
throughout the length of the machine, to which rails are attached brackets 8, 8×;
jointed to these brackets 8, 8*, are frames or cradles 9, 9*, turning upon pins 10, 10*,
passing through the brackets 8, 8*; the arms 9, 9ª, 9*, 9*, of the cradles are
provided with slots or recesses in which are placed pins 11, 11*, upon which the
bobbins 12, 12*, are carried; these bobbins 12, 12*, are pressed against the surface
of the drum 6 by weights 13, 13*, hanging from levers 14, 14*, extending from
the cradles 9, 9*; as the drum 6 revolves the bobbins 12, 12*,being pressed against
the surface of the drum they will be rotated. At 15, 15%, are rails or bars
extending from end to end of the machine, which are provided at intervals with
pins or pegs 16, 16*, which support bobbins 17, 17*. At 18, 18, are rods
extending throughout the length of the machine and supported by the frame or
bracket 19, which is carried by the beam 20 secured to the end framing 1.
At 21, 21, are carrier or guide pullies supported by brackets 22, 22*,
attached to the bars 15, 15*, by means of thumb screws 23, .23*. The
ends 24, 24*, of the yarn from the bobbins 17, 17%, containing the yarn
about to be gassed or singed, are passed over the bars 18, 18*, then around the
pullies 25, 25*, 25**, 25***, between which are situate the gas burners 26, 26*,
by which the yarn will be gassed or singed. At 27 is a rail or bar extending
between the bracket frames 19, which are placed at various parts of the machine;
from this bar project guide wires 28, 28*, between which the yarn passes; the
bar 27 is caused to travel to and fro in the direction of its length by means of any
ordinary copping or traversing motion, thereby building the yarn upon the
bobbins 12, 12x. The guide wires 28, 28*, are attached to brackets 29, 29*,
which are fixed upon the rail 27 by screws 30, 30*, so as to be capable of
adjustment. The yarns are passed over the guide pullies 21, 21*, and around the
barrel of the bobbins 12, 12*, upon which it is wound by means of the drum or
pulley 6; the said drum or pulley 6 may if desired be provided with additional
cradles similar to those shown, so as to be capable of acting upon a greater number
of bobbins at the same time, in which case the drum 6 will require to be made of
increased diameter. The second part of our Invention relates to an arrangement
whereby we are enabled to place the bobbin upon which the yarn is wound after
being gassed or singed in or out of contact with the winding on drum, and
simultaneously operate upon the gas flame or burner by which the yarn is gassed
or singed.

page_text: From the cradle 9 carrying the bobbin 12, upon which the yarn is wound by
means of the drum 6 after being gassed, projects a double ended lever 14, one
end 14 thereof being provided with a weight 13, and the other end 14** with a
pin 15 projecting from the side thereof and passing through a slot formed in one
end of a rod 32, the other end 33 of this rod being formed as a handle. From one side
of the rod 32 depends a part 34, the lower part of which contains a notch 35.
At 36 is a rail extending from one end frame of the machine to the other; pendent
from this rail and attached thereto is a bracket 37; within this bracket is formed
an opening within which slides the rod 32.
The positions of the parts as shewn in the Drawing are those occupied when the
yarn is being wound upon the bobbin 12 after being gassed, the weight 13 forcing
the bobbin against the "winding on "drum 6.
"
When it is desired to arrest such winding on of the yarn upon the bobbin 12 or
for piecing up when broken, the rod 32 is thrust inwards in the direction of the
arrow thereon; such inward movement will bring one end of the slot 38 formed
therein in contact therein with the projecting pin 15 of the lever 14** extending
from the cradle, and a further movement will cause the cradle 9 to be turned in
the direction of the arrow thereon, and to be thereby removed from contact with
the winding on drum 6, the "winding on being thereby arrested. The inward
movement of the rod 32 will have brought the notch 35 over the lower part 37* of the
bracket 37, and the notch 35 embracing the part 37 will retain the rod 32 in its
inward position and so keep the bobbin out of contact with the "winding on drum.
When it is desired to again replace the bobbin in contact with the "winding on
drum, the notch 35 of the rod 32 is liberated from the part 37A of the bracket 37,
and the weight 13 will drawn down the lever 14 until the bobbin is again in
contact with the winding on drum 6, when the "winding on" will recommence.
"
"
Within the rod 32 is formed a slot 40, seen in the detached plan view, Fig. 3;
through this slot passes the tube 41 of the gas burner 26, which tube is jointed at
its lower end to the gas supply pipe 42 extending along the frame or macbine.
The pipe or tube 41 passes through a slot formed in the rail 26; the said pipe or
tube 41 is provided at its upper end with a burner, in which are apertures from
which the gas flame issues to act upon the yarn for singeing as it passes between
the guide pullies 25, 25*. The lower part of the opening within the bracket 37
through which the rod 32 passes corresponds in, width with the parallel part of the
rod 32. So long as this part of the rod 32 is lying upon the lower part of the
opening within the bracket 37, the gas burner tube 41 is kept upright and in
position for the flame acting upon the yarn, but when the rod 32 is thrust inwards
to arrest the motion of the bobbin, an incline 43 formed upon a broader part 32×
of the rod 32 coming in contact with one side A of the opening in the bracket 37,
causes the rod 32 to be forced laterally in the direction of the arrow, see Fig. 3,
such lateral movement of the rod will carry the tube 41 of the gas burner along
with it, thereby removing the gas flame from contact with the yarn simultaneously
with the withdrawal of the bobbin 12 from contact with the "winding on
drum 6. To permit the lateral movement of the rod 32, the side B of the opening
When
in the bracket 37 through which the rod 32 passes is formed as an incline.
the rod is in its upward position, the broad part 32* of the rod 32 will be supported
by the upper part of the inclined side B of the opening formed in the bracket 37.
When the rod is again drawn outwards in a direction contrary to that of the arrow
thereon, in order to allow the bobbin to be again in contact with the winding on
drum 6, the inclined side B of the bracket 37 will compel the rod 32 to move into
the position shown in the Drawing, and thereby bring the burner 26 into position
for acting upon the yarn. As the quantity of yarn wound upon the bobbin 12
increases, the cradle 9 will be turned away from the winding on drum; such
"drum,
movement will carry the end 14* of the lever 14 towards the "winding on
the slot 45 formed in the end of the rod 32 allowing such movement to take place
without the rod 32 being also moved thereby. Hitherto in reference to this second
"

page_text: head of our Invention, we have described the apparatus at one side of the machine
only, but it will be seen from the Drawing that such apparatus is repeated on the
other side thereof, the same Figures of reference being placed thereon with the
addition of the letter S.
The third part of our improvements refer to the brackets used for supporting
the guide pullies or bowles used in gassing frames, around which the yarn passes
while being gassed or singed, and consists in forming the said bracket with two
projecting arms which carry the two rollers or bowls aforesaid. Upon the rail 36
is bolted a bracket 50, shown upon an enlarged scale in Figs. 4 and 5, Sheet 2, to
which is attached a bracket 51 formed with two arms 51, 51**, extending
upwards, the ends thereof carrying studs 52 screwed in to the armis 51, 51**, upon
which studs are mounted the pullies or bowls 25, 25*, around and between which
the yarn 24 passes during the process of gassing. By forming the bracket 51 with
two projecting arms 51*, 51**, I ensure the pullies 53, 54, being in their proper
relative positions with regard to each other, one adjustment of the bracket 51
answering for both the bowles or pullies.
The fourth part of our Invention relates to a method of mounting the pullies or
bowls aforesaid, around which the yarn passes while being gassed or singed.
Fig. 4, Sheet 2, shows in elevation the bracket previously described with reference
to the third part of our improvements. Fig. 5 is a plan view thereof, and
Fig. 6 shows in section one end of the bracket 51*, and the bowl carried thereby.
Into the end of one of the arms 51* of the bracket 51 is screwed a stud 52, upon
which is mounted a bush 53 capable of revolving freely thereon; upon the stud 52
is formed a collar 54, such collar retaining the bush 53 upon the stud 52. Upon
the bush 53 is placed the bowl or guide pulley 25, the bush being formed as a cone,
and the central hole of the pulley being also formed conical to correspond with the
bush, the smaller diameter of the cone being at the outer end of the stud 52, so
that when the bow! 25 is placed upon the bush it will be retained thereon, but
when it is desired to remove the bowl for cleaning or any other purpose, the said
bowl can be again readily removed from the bush, which will remain upon the
stud 52. Through the bush 53 I form slits or apertures, such apertures serving
the double purpose of retaining oil or other lubricant, and also facilitating the
cleaning of the bush or stud, without their requiring to be removed from the
bracket 51* to which they are attached. When the bowl or pulley 25 is placed
upon the bush 53, the oil or other lubricant is retained therein, and extraneous
matter is excluded.
The fifth part of our Invention consists in arrangements whereby we prevent the
yarn or thread running off at the ends of the bowls or pullies around which it
passes whilst being gassed or singed. Upon one end of the bowl or pulley we form
an enlarged part or flange 56, which tends to prevent the yarn or thread from
running off at one end, and we prevent the running off at the other end by forming
a projecting part 57 upon the bracket 51 carrying the stud 52 upon which the
bowl 25 revolves, such projecting part overhanging the opposite end of the bowl to
the flange 53, and serving as a guide to the yarn, and preventing its passing beyond
the end of the bowl or pulley 25.
Having thus described the nature of our said Invention, and the manner in which
the same is to be performed, I desire it to be understood that we claim under the
bove in part recited Letters Patent,-
Firstly. The use of one row of drums by which the yarn or thread is wound
apon bobbins after being gassed or singed, each of such drums acting upon two or
nore bobbins.
Secondly. The arrangement for acting upon the gas burner and upon the bobbin
pon which the gassed yarn is wound, for putting them in or out of action,
ubstantially as described and shown.
Thirdly. Carrying the guide pullies 25, 25*, upon one bracket or support.
Fourthly. Mounting the guide pullies 25, 25*, upon bushes turning upon studs
r pins, and forming such bushes with apertures for containing the lubricant.

page_text: Fifthly. Forming a flange around one end of each of the guide pullies 25, 25*,
and a projecting part upon their supporting bracket, for the purpose above
described.
In witness whereof, I, the said William Thomas Stubbs, have hereunto set
my hand and seal, this Thirty first day of March, in the year of our
Lord One thousand eight hundred and eighty one.
