Improved Means for Regulating the Drag on the Bobbins or Spools
in Spinning Machines.
I-JOSEPH WOOD of The Boggs, Allerton near Bradford in the County of York,
Mechanic, do hereby declare the nature of this invention to be as follows, that is to
say:
It consists of improvements in or appertaining to spinning machines whereby the
tension of the yarns or threads, being spun, is regulated so as to be even throughout
the entire operation from the beginning of the empty bobbin or spool unto the filling
or finishing of same.
.
As is well known in connection with spinning machinery of the class .wherein.the
winding of the threads or yarns upon the bobbins or spools is effected by said
bobbins or spools being retarded in their movements or revolutions around their
several spindles the difficulty experienced has been the regulating of the retarding
means (usually consisting of a frictioning washer of cloth felt or the like) during
the filling of said hobbins, or spools said filling of the bobbins or spools with the
winding thereon of the yarns or threads, adding to their weight and consequently
to the friction between them and their supporting surfaces, so that the yarns or
threads wound thereon have been loosely held at the beginning of the empty bobbin
or spool and more tightly held as the filling has progressed until in many cases
before the completion of said filling said yarns or threads have broken by the
excessive strain upon them.
..
F
To obviate this and so attain the object of my invention, I mount the washers
(which are of the material stated) upon which the bobbin or spools rests, in such a
manner that as the said bobbins or spools increase in bulk and weight, said washers
are automatically withdrawn from beneath them, thus lessening the frictioning. or
retarding surface acting upon the bobbins or spools.
To effect this withdrawal of said washers I form their central openings of an
elongated or slotted shape, and attach them to an intervening plate or rail that is
mounted upon the usual and well known plate or rail, this intervening plate having
a lateral movement imparted to it by any well-known means such as incline, cam
rack and pinion or other mechanism, operated from any of the motor parts of the
machine.

Improved Means for Regulating the Drag on the Bobbins or Spools
in Spinning Machines.
I, JOSEPH WOOD of The Boggs, Allerton near Bradford in the County of York,
Mechanic, 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, that is to say
It consists of improvements in or appertaining to spinning machines whereby the

page_text: tension of the yarns or threads being spun, is regulated so as to be even throughout
the entire operation from the beginning of the empty bobbin or spool unto the
filling or finishing of same.
In the accompanying sheet of drawings illustrative of this invention :-
Fig. 1 is front elevation of a sufficient portion of a spinning frame to show the
application of my improvements.
Fig. 2 is part sectional view of certain of the parts shown by Fig. 1 and as seen
from above.
Figs. 3 and 4 are similar views to Figs. 1 and 2 respectively, but show how the
relative positions of the parts are changed when in operation.
Figs. 5 and 6 are drawings in detail illustrative of several alternative arrange-
ments of parts hereinafter fully explained.
In connection with spinning machinery of the class wherein the winding of the
threads or yarns upon the bobbins or spools is effected by said bobbins or spools
being retarded in their movements or revolutions around their spindles the difficulty
experienced has been the regulating of the retarding or dragging means (usually
consisting of a retarding washer of cloth, felt or the like) during the filling of the
bobbins or spools, said filling of the bobbins or spools with the winding thereon of
the yarns or threads adding to their weight and consequently to the friction
between them and their supporting surfaces so that as the yarns of threads wound.
thereon have been loosely held at the beginning of the empty bobbin or spool and
more tightly held as the filling has progressed until in many cases before the
completion of said filling said yarns or threads have broken under or by the
excessive strain upon them.
To obviate this and so attain the object of my invention I place the washers a
(which are of the usual material) upon which the bobbins or spools brest, upon a
metal plate c which is attached to and carried by the plate d resting upon the
lifter-plate e with which it rises and falls as said lifter-plate moves to cause the
spreading of the yarns or threads over the entire lengths of the bobbins b as is
well understood. In addition to the rising and falling movements of this plate da.
lateral or longitudinal movement is imparted to it so as to cause it to withdraw its
several plates c from beneath the bobbins b in order that the full parts 2 of said
plates may be moved out of frictional contact with said bobbins b while the
narrowed parts 3 are moved into such contact by which means the surface upon
which the washers a rotate is lessened so also is the friction between these surfaces
lessened.
To effect the withdrawal of the plate cat the proper time relatively with the
filling of the bobbins & which withdrawal is always when the lifter-plate e
approaches its lowest position, an inclined piece g' is mounted upon the framework h
so that the antifriction bowl k carried by au arm m attached to the plate d may
operate thereon and be moved thereby into the position shewn by Figs. 3 and 4.
The slots or elongated openings in said plate d as also in the plates c allowing this
movement to be effected. The return movement of this plate d into its position
shown by Figs. 1 and 2 is effected by a spiral or other spring when the inclined
piece is employed or again another inclined piece fixed to the opposite end of the
machine and having its inclined surface in an opposite direction to that of the
piece g might be employed.
Or again the rack and pinion and crank mechanism shewn by Fig. 5 might be
employed instead of the incline and spring mechanism above described. In this
case the rack n is attached to the framework h while the pinion o and crank pin p
are carried by the lifter-plate e. The plate & being coupled to the crank pin p by
means of the rod pl.
Or the cams (shown by Fig. 6) might be substituted for the crank pin p and the
antifriction bowlt (shewn in broken lines) for the rod pl, in both of these latter
arrangements the plate d may be operated in both directions by the employment of
only one set of mechanism.

page_text: 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 :-
1. The arrangement and combination of means whereby the frictional surface
for retarding the movements of bobbins or spools in spinning or like machines,
is diminished or increased substantially as and for the purposes herein specified.
Dated this 6th day of October 1892.
