PROVISIONAL SPECIFICATION.
Improvements in Machines for Reeling Yarn..
I, DAVID WEBSTER, of the firm of David Webster and Son, of Bervie, in the
County of Kincardine, N.B., Flaxspinner, do hereby declare the nature of this
invention to be as follows:-
The object of my invention is to regulate the speed of the reels in reeling
machines which are driven by means of friction rollers or pulleys; that is to say, to
allow of the number of revolutions per minute, of the reel varying proportionately
to the tension upon the threads of yarn which are being reeled.
I carry out my invention in an improved manner and by means of improved
apparatus.
In carrying out my invention I fix to the end frame, or gable of the machine, a
bracket for the purpose of carrying a bent lever; at the one end of which is a
pointed piece of metal and at the other a weight, the whole arrangement being such,
that the pointer is pressed against the end of the reel arbor, the pressure being
communicated through said arbor to the friction rollers.
Above the bent lever is another bracket in which a wheel and small pulley is
supported, the pulley being connected to the bent lever by means of a leather belt
or cord, the contrivance being for the purpose of taking off the pressure from the
reel arbor when it is necessary to stop the machine.

Improvements in Machines for Reeling Yarn.
I, DAVID WEBSTER, of the firm of David Webster and Son, Bervie, in the
County of Kincardine, N.B., Flaxspinner, 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:-
The object of my invention is to regulate the speed of the reels in reeling
machines which are driven by means of friction rollers or pulleys; that is to say,
to allow of the number of revolutions per minute, of the reel varying proportionately
to the tension upon the threads of yarn which are being reeled.
I carry out my invention in an improved manner and by means of improved
apparatus.
The accompanying sheet of explanatory drawings illustrates the method of
carrying out my invention, according to one modification.
Figure 1. represents a front and Figure 2. an end elevation of a reeling machine
fitted with my improvements.
For convenience, and to simplify the drawing, I have only, shown in Figure 1.
the two ends, or extremities of the reeling machine, and for a similar reason in
Figure 2, only one side of the machine.
In these drawings the same reference numerals are used to mark the same, or
like parts wherever they are repeated.
In carrying out my invention, I fix to the end frame or gable 3. of the machine, a
bracket 4. for the purpose of carrying a bent lever 5; at the one end of which is a
pointed piece of metal 6. and at the other a weight 7; the whole arrangement
being such, that when the pointer 6. is pressed against the end of the reel arbor 8,

page_text: the pressure is communicated through said arbor to the friction rollers 9. and 10.
which thus cause the arbor and the reel 11. to rotate.
Above the bent lever 5. is another bracket 12. in which a wheel 13. and small
pulley 14. is supported, the pulley being connected to the bent lever by means of a
leather belt or cord 15; the contrivance being for the purpose of taking off the
pressure from the reel arbor, when it is necessary to stop the machine.
The machine is used in the following manner :-
The yarn, which is to be reeled has previously, in the usual course of manufacture,
been wound upon bobbins 16. which are placed in the reeling. machine,as shown.
The threads 17. are then led to the reél 11.-which is caused to rotate in the
direction of the arrow, by means of the friction pulleys as previously explained-
and is wound thereon. It is obvious, that when the bobbins 16. are filled with
thread they will be made to rotate with less tension on the threads, than when they
are nearly empty because of the greater radius at which the force acts, when they
are full. By pressing the reel arbor 8; and through it the friction pulley 9. against
the other friction pulley 10. by means of a constant force such as that obtained by
the combination of the weight 7. and bent lever 5, the threads cannot be wound
upon the reel at a tension greater than that due to the pressure with which the
friction pulleys are pressed together; any tension exceeding that causing the said
friction pulleys to slip, and thus either stopping the rotation of the reel or making
it to move more slowly. In practice, the reel rotates rapidly when the bobbins are
full, gradually slackening speed as they empty.
•
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same to be performed, I declare that what I
claim is :-
(1) In machines for reeling yarn, the construction and arrangement of parts for
applying pressure to the reel arbor and friction pulleys, substantially as and for the
purposes set forth.
(2) In machines for reeling yarn, the general construction, combination and
arrangement of parts, substantially as and for the purposes herein set forth, together
with any mere modification or modifications thereof.
(3) In machines for reeling yarn, the use of the wheel 13, pulley 14, and strap 15,
substantially as and for the purposes set forth.
