Year: 1885

We, FREDERICK WILLIAM LAWSON, of Hope Foundry, Leeds, in the County of
York, Engineer, and THOMAS KILVINGTON HATTERSLEY, of the Spindle Works,
Armley Road, Leeds, in the County of York, Spindle Manufacturer do hereby
declare the nature of our invention for AN IMPROVED MODE OF ATTACHING
FLYERS TO SPINDLES USED IN TEXTILE MACHINERY to be as follows:-
This improvement relates to a method of attaching the flyer to the spindle,
whereby a simple and effected "lock" is obtained.
Ordinarily flyers are secured to their spindles by means of screw threads; other
modes have also being adopted such as helical grooves, pins in the flyers, & other
such contrivances more or less complicated.
I accomplish my object as follows:-The flyer is provided with a short central
leg, extending downwards, which fits into a corresponding hole in the spindle top.
Further, the top part of the spindle blade is slotted away so as to permit the flyer
itself to drop into it. Portions of the lowest part of this slot or groove are recessed
out on the sides necessary to allow the flyer, after entering, to lock itself.
This locking recess takes up a diagonal position across the bottom of the slot in
the direction such as is requisite to permit the revolving flyer to lock.
By making recesses in both directions the flyer may be made to lock itself
whichever way it is revolved.
The whole arrangement permits of all being made without any pins, or other
loose pieces, and consequently it is less liable to get out of order.
Dated this Eleventh day of June 1885.

We, FREDERICK WILLIAM LAWSON, of Hope Foundry, Leeds, in the County of
York, Engineer, and THOMAS ĶILVINGTON HATTERSLEY, of the Spindle Works,
Armley Road, Leeds, in the County of York, Spindle Manufacturer, do hereby
declare the nature of our invention for AN IMPROVED MODE OF ATTACHING
FLYERS TO SPINDLES USED IN TEXTILE MACHINERY, and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement:—
This improvement relates to a method of attaching the flyer to the spindle,
whereby a simple and effective "lock" is obtained.
Ordinarily flyers are secured to their spindles by means of screw threads; other
modes have also been adopted such as helical grooves, pins in the flyers, and other
such contrivances more or less complicated.
We accomplish our object as follows:-The flyer is provided with a short central
leg, extending downwards, which fits into a corresponding hole in the spindle top.
Further, the top part of the spindle blade is slotted away so as to permit the flyer
itself to drop into it. Portions of the lowest part of this slot or groove are recessed
but on the sides necessary to allow the flyer, after entering, to lock itself.
The locking recess takes up a diagonal position across the bottom of the slot in
the direction such as is requisite to permit the revolving flyer to lock.
By making recesses in both directions the flyer may be made to lock itself
whichever way it is revolved.
The whole arrangement permits of all being made without any pins, or other
loose pieces, and consequently it is less liable to get out of order.
In order to fully explain the manner in which we carry our invention into effect
we have annexed a drawing. The same letters refer to the same parts in all the
figures.
Fig. 1. is an elevation of the flyer A. A. having a central leg B. Fig. 2. is a plan
of the same, and Fig. 3. a side sectional elevation cutting through the shoulder and
showing the central leg B.
Fig. 4. is a front elevation of the spindle C. showing a central hole B' at its top,"
into which the flyer leg B can drop.
Figs. 5. & 6. form, respectively, the plan and side elevation of this spindle and
show the portion slotted away to allow the shoulder of the flyer to drop into it.
The bottom of the slot is shown recessed out at the near side in Fig. 6. at A¹, so as
to allow the flyer to lock after it has reached the bottom of the slot, supposing the
revolution of the spindle takes place in the direction shown by the arrow.
contrary revolution be given the near recess would be as shown in Fig. 7. This
locking recess takes up a diagonal position at the bottom of the slot as shown in
dotted lines in Fig. 5.
If a
By making recesses in both directions, as shown in Figs. 8. & 9, the flyer would
get locked whichever way the spindle revolved-but this double recessing, in the
case of spindles of small diameters, is not recommended, as it weakens the spindle
top. This is shown in plan in Fig. 9.

page_text: Figs. 11. 12. & 13. which are, respectively, Front Elevation, Plan, and Side
Elevation, show the flyer, locked, in a spindle revolving in the direction shown by
the arrow.
The whole arrangement as described and shown, permits of all being made
without pins, or other loose pieces, and consequently it is less liable to get out of
order. This we consider the best plan, but we do not bind ourselves to make
everything solid, for instance, the leg B. of the flyer A. A. might be made separately
and afterwards be fixed in any suitable way in the shoulder of the flyer, as
shown-riveted-at Fig. 10.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:―
The mode of attaching flyers-made with a central leg-to their spindles, which
causes them to be locked so long as they are kept revolving, substantially as
described herein, and as shown on the accompanying drawing.
