Improvements relating to Brakes or Stopping Appliances in
connection with Spindles for Spinning, Twisting, Winding,
and Doubling Purposes.
ALFRED HITCHON, Machine Salesman and JAMES LUCAS, Foreman Mechanic,
both of Globe Works, Accrington, Lancashire, do hereby declare the nature of this
invention to be as follows:-
The first part of our invention admits of our giving a double use to what is
usually known as the spindle holder, such as illustrated and described in Letters
Patent granted to Samuel Tweedale, No. 2799-A.D. 1882, wherein is illustrated
an upright stud 1, and hook 7, also wharle 6. On the upper part of the spindle
wharle or the like we form one or more toothlike projections or notches, so that by
an upright movement of the spindle or serrated wharle, the same would be brought
in contact with the hook part 7, or other like stud provided for this purpose,
whereby the revolving action of the spindle would be held, thus causing the spindle
driving hand to slide round the aforesaid wharle, thereby allowing the attendant to
have both hands at liberty for piecing and doffing purposes. The projections
or notches provided on the wharle are preferably made in an angular direction to
the line of axis of the spindle and also may be made in a tangential direction to the
axis, so that the revolving serrated wharle when brought in contact with the
hook 7, gets hooked on the same, and thereby the revolving action is effectually
stopped. It will also be seen that the pull of the driving band will keep the
projections or notches on the lately revolving spindle wharle in position with the
hook 7, or other like stud provided for this purpose.
The latter part of our invention applies to a means of arresting the revolving
action of the spindle when the same has been placed in position, by a kind of brake
plate faced with leather or other like soft substance which is formed to come
against the rim of the spindle wharle.. The lower part of the aforesaid brake plate
is of sufficient length to reach to the lower end of the spindle bolster, and on which
are provided two lugs, through which the spindle bolster passes. The bolster lug
is provided with a screw which passes through the side of the lug or ear, iuto
a groove or countersink formed in the lower end of the spindle bolster, thus holding
the brake plate loosely in position, which admits of the pressure of the attendant's
knee being brought to bear against the upper part of the brake plate, thereby
arresting the revolving action of the spindle, for samelike purposes as before
described. The brake plate being out of plumb line falls away from the spindle
wharle by its own weight by the action of gravity and is prevented from falling too
far away by the back of the aforesaid upper lug or ear through which the spindle
bolster is passed coming against the same.

connection with Spindles for Spinning, 'Twisting, Winding,
and Doubling Purposes.
ALFRED HITCHON, Machine Salesman, and JAMES,LUCAS, Foreman Mechanic,
both of Globe Works, Accrington, Lancashire, do hereby declare the nature of
this invention and in what manner the same is. to be performed, tto, be particularly
described and ascertained in and by, the following statement:-
The first part of our invention admits of our giving a double use to what is
usually known as the spindle holder, such as illustrated and described in Letters
Patent granted to Samuel Tweedale, No. 2799, A.D. 1882, wherein is. illustrated
an upright stud 1 and hook 7., also wharle 6.
In Tweedale's Patent, hook 7 serves when in a normal position the purpose of,
preventing the spindle from being withdrawn out of the bearing until hook 7 is
moved, whereas we make book 7 serve the same purpose besides being made to act
as a brake for the spindle, wharle.
On the upper part of the spindle wharle we form one or more notches, so
arranged that on the spindle being stopped and lifted by hand, the notch is made
to engage with the hook 7, or other like stud provided for this purpose, whereby
the revolving action of the spindle would be held, until the spindle is pushed down
into the bearing by the action of pressing the bobbin on to the spindle when the
notch leaves the catch, and leaves the spindle free to revolve.
The notches provided on the wharle are preferably made in an angular direction
to the line of axis of the spindle, and also may be made in a tangential direction to
the axis, so that the revolving notched wharle when brought into contact
with the hook 7, gets hooked on same, and thereby the revolving action is
effectually stopped.
It will also be seen that the pull of the driving band will keep the notches on the
lately revolving spindle wharle in position with the hook 7, or other like stud
provided for this purpose.
The latter part of our invention applies to a means of arresting the revolving
action of the spindle when the same has been placed in position, by a kind of brake
plate faced with leather or other like soft substance, which is formed to come
against the rim of the spindle wharle.
The lower part of the aforesaid brake plate is of sufficient length, to reach the
lower end of the spindle bolster, and one which is provided with two lugs, through
which the spindle bolster passes.
The bottom lug is provided with a screw which passes through the side of the
lug or ear, into a groove or countersink formed in the lower end of the spindle
bolster, thus holding the brake plate loosely in position, which admits of the
pressure of the attendant's knee being brought to bear against the upper part of
the brake plate, thereby arresting the revolving action of the spindle, for samelike
purposes as before described.
The brake plate being out of plumb line falls away from the spindle wharle by its
own weight by the action of gravity, and is prevented from falling too far away by
the back of the aforesaid upper lug or ear through which the spindle bolster is
passed, coming against the same.
By the accompanying sheet of drawings, our invention may be fully understood
as to where the same is applied to which parts we make reference figures.
Spindle,wharle 6 is partly sectioned to better illustrate one of the notch holes 8,
as made in the wharle in an angular direction for beut hook 7, to engage with, when
the spindle wharle is raised in contact with same the revolving motion of the

page_text: spindles will be with-held. 9 is the brake plate faced with leather or the like at 10.
Bottom lug or ear at 11 carried by point of set screw 12, and retained from falling
too far away by upper lug 13.
Having now particularly described and ascertained the nature of the said
invention and in which manner the same is to be performed, we declare that what we
claim is :-
Stopping or brake appliance constructed and applied to spinning, twisting,
winding and doubling spindles in like manner as illustrated and described in this
Specification.
