Year: 1878

page_text: LETTERS PATENT to William Dawes, of Kingston Grove, Leeds, in the
County of York, Engineer, for the Invention of "IMPROVEMENTS IN AUTOMATIC
SPOOL OR BOBBIN WINDERS."
Sealed the 21st January 1879, and dated the 24th July 1878.
PROVISIONAL SPECIFICATION left by the said William Dawes at the Office
of the Commissioners of Patents on the 24th July 1878.

"IMPROVEMENTS IN AUTOMATIC SPOOL OR BOBBIN WINDERS."
To obtain greater uniformity and certainty of action and thereby a more
completely wound and perfect sample than heretofore I arrange and construct my
winder in such a manner that the following features or peculiarities are embodied,
that is to say :-
I first place an independent "bobbin pin" for receiving the full or ordinary
bobbin or reel from which the thread is taken, and at a convenient distance from
this I place a guide and tension pin or standard, and I prefer that both, or at least
the latter of these, shall be at or near the right-hand back corner of the machine,
either that part of the machine itself, or in some cases upon the same corner of the
top of the machine table or stand.
I next fix the shuttle bobbin winder near the right-hand front corner of the
machine, and by preference upon the table top so as not to interfere with the
turning over of the machine for oiling and cleaning, and by this arrangement of
the before-named parts I obtain a long horizontal length or distance between the
guide and tension pin and the winder, and thus reduce the angles formed between
the thread and the axis of the bobbin as the thread in coiling approaches the ends
of the bobbin.
I next construct the guiding or controlling portion of my winder with two or
more parallel bars, over, under, between, and against (but not "round") which the
thread is caused to pass and press before being wound upon the bobbin, and to

page_text: assist the thread in travelling from end to end as it coils upon the bobbin I shape,
slope, or form one side of each of these bars (against which the thread presses)
with a convex or curved surface, and this to a different extent or degree in each bar,
and thus by slightly turning these bars in their sockets or bearings ("fixings"),
the pressure of the thread upon these convex surfaces can, by a choice or preference
of the extent of face or angle of the same, be made to. control the "lapping on
angle of the thread as it approaches to or recedes from the ends of the bobbin.
"
Having according to the foregoing description constructed and fixed the different
parts of the winder so that uniformity and certainty of "lapping on " angle can be
obtained, and that adjustably, I now construct the "presser or "pressers" for
giving firmness and solidity to the portion wound as it progresses, and to this end
and also for preventing the thread from "mounting" and reversing the "lap" beforo
reaching the ends of the bobbin I employ two (or more) pressers in lieu of one,
acting at about ninety degrees from or after each other, the face of the one nearest
to the straight advancing thread being "rounded off" at the ends, and the other
being allowed to press the full length of the bobbin, the benefit arising from the
joint action of the two or more pressers being caused by the slight ease or gathering
tendency given to the last lap of thread between the pressers.
In some cases I unite the pressers so as to constitute a compound or a double
compound presser acted upon by our spring, and when the former, the surfaces may
be two plain surfaces at right angles or thereabouts to each other.
In some cases I employ a spring or other catch for holding the pressers out of
action whilst inserting the bobbin in the winder.

"IMPROVEMENTS IN AUTOMATIC SPOOL OR BOBBIN WINDERS."
To obtain greater uniformity and certainty of action and a more completely and
tightly wound and perfect sample than heretofore, I arrange and construct my
automatic winder in such a manner that the following features or peculiarities
are embodied, that is to say :-
I first place an independent "bobbin pin" for receiving the ordinary bobbin or
reel from which the thread is taken, and at a convenient distance from this I place
a guide and tension pin or standard, and I prefer that both, or at least the latter of
these, shall be at or near the right-hand back corner of the machine, either upon
that part of the machine itself or in some cases upon the same corner of the top of
the machine table or stand.
I next fix the shuttle bobbin winder near the right-hand front corner of the
machine, and by preference upon the table top, so as not to interfere with the
turning over of the machine for oiling and cleaning, and by this arrangement of
the before-named parts I obtain a long horizontal length or distance between the
guide and tension pin and the winder, and thus reduce the angles formed between
the thread and the axis of the bobbin as the thread in coiling approaches the ends
of the bobbin.
I next construct the guiding or controlling portion of my winder with two or
more parallel bars over, under, between, and against, but not "round," which the
thread is caused to pass and press on its way to and before being wound upon the
bobbin, and to assist the thread in travelling from end to end as it coils upon the
bobbin I shape, slope, or form one side of each of these bars (against which the
thread presses) with a convex or curved surface, and this to a different extent or
degree in each bar, and thus by slightly turning these bars in their sockets or
bearings ("fixings"), the pressure of the thread upon these convex surfaces can, by
a choice or preference of the extent of face or angle of the same, be made to control
the "lapping on" angle of the thread as it approaches to or recedes from the ends
of the bobbin.
"
r
Having, according to the foregoing description, constructed and fixed the different
parts of the winder so that uniformity and certainty of "lapping on" angle can be
obtained, and that adjustably I now construct the " presser or pressers" for
giving firmness and solidity to the portion wound as it progresses, and to this end,
and also for the purpose of preventing the thread from "mounting" and reversing
the "laps" before reaching the ends of the bobbin, I employ two or more pressers in
lieu of one, acting at about ninety degrees from or after each other, the face of the
one nearest to the straight advancing thread being "rounded off" at the ends, and
the other being allowed to press upon the thread the full length of the bobbin, the
benefit arising from the joint action of the compound pressers being caused by
the slight ease or gathering tendency given to each "last lap" of the thread between
the pressers.
I prefer in most cases to unite the pressers so as to constitute a "compound" or
double presser in one, and acted upon by one spring, the pressing surfaces then
being two plain surfaces at "right angles" or thereabouts to each other.
In some cases I employ a spring or other "catch" for holding the presser out of
action whilst inserting the bobbin in the winder.
In the accompanying Drawings a is the bobbin pin; b, the guide and tension pin;
c, the frame of the winder; d, the bobbin; e, the parallel "shaped" or flattened
guide bars; and f the compound presser.
Having now described and particularly ascertained the nature of the said In-
vention, and the manner in which the same is or may be used or carried into effect,

page_text: I wish it to be understood that I do not confine or restrict myself to the precise
details or arrangements which I have described or refferred to, as many modifica-
tions and variations may be made therefrom without deviating from the principles
or main features of the said Invention," but what I consider to be novel and
original, and therefore claim as the Invention secured to me by the herein-before
in part recited Letters Patent is,-
First. An independent guide or standard fitted with an additional adjustable
tension appliance, and placed upon the back half or part of the machine plate or
the table.
Second. The application and use of two or more adjustable guide bars, each
having shaped flats or convex surfaces for the thread to pass over or against, and
thus the gathering into position and the obtaining of the proper angle of the thread
for winding upon the spool or bobbin are accomplished at twice, and therefore with
greater ease and certainty than at once.
Third. The application and use of a pair of or a compound presser for improving
the "lapping on of the thread, and allowing a much greater tension to be used, and
thereby increasing the quantity of thread wound upon the bobbin, for the purposes
and virtually as or after the manner of the foregoing description.
In witness whereof, I, the said William Dawes, have hereunto set my hand
and seal, this Twenty-second day of January, in the year of our Lord One:
thousand eight hundred and seventy-nine.
