IMPROVEMENTS IN AND RELATING TO APPARATUS FOR WINDING YARN OR OTHER MATERIAL
Year: 1884

page_text: 1, WILLIAM ROBERT LAKE, of the firm of Haseltino Lake, & Co., Patent Agents,
Southampton Buildings, London in the County of Middlesex do hereby declare the
nature of said Invention for "IMPROVEMENTS IN AND RELATING TO APPARATUS
FOR WINDING YARN OR OTHER MATERIAL" and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:
This Invention relates to an improved winding machine by means of which the
yarn spooled from the cops is automatically wound upon spools or bobbins in cross
layers; each spool or bobbin is provided with a self-acting stop-motion device by
means of which it is automatically thrown out of gear as soon as it has attained a
certain diameter or when a break of the yarn occurs without the working of the
other bobbins, and of the whole machine being interrupted hereby.
In the accompanying Drawing,
Figure 1 is a side elevation, partly in section, of a machine constructed
according to this Invention.
Figure 2 is a front elevation, partly in section, of a portion of the machine drawn
to an enlarged scale, and
Figure 3 is a view of the brake-device for stopping the yarn-guiding drum.
The yarn is wound from a cop b fitted in a step-bearing a, it then passes
through a yarn-guide c over a rod d of glass or metal, over a cushion e, and beneath
a rod whence it is conducted through a drum g and wound upon a hollow
cylinder of paper or the like or upon a wooden spool, this hollow cylinder or
spool being fitted upon a shaft. The journals of this shaft have bearings in the
arms and the spool itself rests with its outward cylindrical surface upon the
cylindrical surface of the drum g, the said drum g being put in rotatory motion by
means of the friction wheels k.
The drum g is composed of two hollow parts so arranged upon a shaft g' that
between these two halves a slit Z is left free through which slit passes the yarn x
before being wound upon the spool h. This slit having the form of a curved line
extending from one edge of the cylindrical drum upwards to the opposite edge and
thence back again downwards to the point of issue, it is obvious that the yarn
after having passed this slit of the drum g whilst the said drum is revolving is

page_text: wound up upon the spool h so that each successive layer applied lies in an opposite
direction or across that beneath it. Instead of the said drum some other analogous
guiding mechanism may be employed, by means of which the above mentioned
reciprocating motion is imparted to the yarn.
In order to enable the automatic stopping of the winding mechanism of each
spool in case of the breakage of the yarn each spool is provided with an automatic
stop-motion-device. Upon the portion of the yarn between the rod d and the
cushion e is suspended a cranked pin m, the bottom end of which is jointed to the
outside arm of a double armed lever n and maintains this outside arm in an
elevated position. As soon as the yarn breaks, the pin m drops and the outside
arm of the double-armed lever n lowers, the opposite inner arm of the said lever
rising. This inner arm is then caught by the edge of a revolving prisin o and
pushed further upwards until it bears against the end of a bar p, the top end of
which is jointed to the arm i carrying the spool h. This bar is jointed to an arm q
(see Figure 2) the back-end of which is fitted to the bottom end of the disengaging
fork whilst its front end forms or bears the brake-shoe s. A spring tends
constantly to press the brake-shoes against the flat surface of the drum y or of the
analogous guiding contrivance. To prevent the constant breaking of the drum the
arang is provided with a nose q' which, under normal circumstances, bears against
the lower edge of a notched guide w, through the notch of which passes the said
arm q. During the normal working of the spooling mechanism this nose q¹ by
catching in the guide uretains the arm g in its backward position and prevents
the pressing of the brake-shoe & against the guiding drum y, but as soon as a
breakage of the yarn occurs, the cranked pin m drops, and the bar is raised, as
above described, and rains upwards the arm q until its nose q' is allowed to slide
through the notch of the guide u. By the lension of the spring & the arm q is
drawn against the guiding drum, whereby the said brake shoes is pressed against
the flat surface of the drum and at the same time the disengaging fork r is made
to tuin round its axis 7. The upper end of the fork r sliding in a groove of the
coupling box of the friction socket is horizontally movable upon the shaft g';
this lateral movement of the fork 7 draws the friction socket out of contact with
the cone whereby the clutch coupling is disengaged. The brake-shoe & being at
the same time pressed against the flat surface of the drum the latter is stopped
at once.
The spool h receives its motion only by its friction on the cylindrical surface of
the druin; therefore as soon as the bar p is raised upwards and raises the arm i
from the drum the surface of the spool comes out of contact with the drum
surface and the spool is also stopped instantaneously.
In Figure 1 the left side represents a spooling device as it appears during its
regular working whilst the right side represents the position of such device at the
moment following the breakage of the yarn.,
When, instead of the drum, another guiding mechanism is employed the said
mechanism must also be provided with a curve-shaped slit for the passage of the
yarn, as well as with a suitable appliance for driving the spool h.
The different spooling devices may be fitted upon one frame opposite each other,
as shewn by Figure 1, and any desired number of such devices may be fitted up
upon one machine according to the length of the san.e, each of these devices
working quite independently of another; all of them are driven by the same main
shalt y.
The re-engaging of the described spooling device after it has been disengaged in
the above described manner, is performed by means of a hand-lever .. By pressing
upon the top of this lever the said arm q is drawn backwards until the nose q' is
caught by the bottom edge of the notched guide t; the brake-shoe is then put
out of contact with the drum y and at the same time the friction clutch and is
connected again.
It is obvious that when the yarn is gradually wound upon the spool the
diameter of the spool, the cylindrical surface of which is in constant contact with

page_text: the cylindrical surface of the drum, gradually increases and its axis is successively
raised up more and more from the drum; thereby the said arm i and the bar p
jointed to this arin, as well as the cross-arm q, are also raised up until the
cross-arm q is raised high enough to disengage the nose q' of this cross-arm and to
allow the same to slide freely through the notch of the guide u.
The nose q'
having a suitable size the automatic disengaging of each spooling device takes place
as soon as a certain length of the yarn has been wound upon the spool ; thus the
spools obtained by the use of this machine are all of the same diameter.
Instead of winding the yarn from one single cop bas represented in the
Drawing several cops b may be fitted upon the step-bearings a and the yarns of
these cops conducted through a corresponding number of guides to the slit of the
drum g and wound up together upon the same spool. In this manner during the
spooling of the yarn a doubling, tripling, and so on of the same may be performed.
In this latter case each yarn is provided with a separate cranked pin m the bottom
end of which is jointed to a lever n.
The application of the above described winding machine offers considerable
advantages. The yarn can be spooled upon very thin hollow cylinders made of
paper or the like and fitted upon an axis or pin whereby the application of the
flanged wooden bobbins having generally a considerable weight can be dispensed
with.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
First. Automatically winding yarn in such a manner that the material of each
successive layer crosses the material of the layer below it, this result being obtained
by conducting the yarn through the slit of a guiding drum of the forin shewn in
Figure 2 or of similar form substantially as described.
Second. A levice for automatically winding yarn the successive layers of which
cross each other, the said device consisting of a spoel h resting upon a drum or
upon some other suitable guiding device, the said drum g or analogous guiding
device being provided with a curve-shaped slit & conducting the yarn and extending
from one point of the same to the point opposite and then coming back again to its
point of issue and having finally a rotatory movement by means of which a like
imovement is imparted to the spool whereby the yarn is wound upon it substantially
as shewn and spre fied.
Third. A winding machine comprising any desired number of winding devices
of the above described construction cich of them working automatically and
independently of the other and being driven from the main-shaft by means of a
coupling; the working of the said machine being such that the coupling of each
separate winding device is automatically disengaged as soon as either the winding
of a spool is terminated or a breakage of the yarn occurs so that either winding
device may be thrown out of gear without the regular working of the other
winding devices being affected thereby substantially as shewn and set forth.
