I THOMAS ASHWORTH of Woodlands Davyhulme near Manchester in the County
of Lancaster Cotton Spinner do hereby declare the nature of my invention for
"IMPROVEMENTS IN APPARATUS FOR SPINNING AND DOUBLING COTTON AND OTHER
FIBROUS SUBSTANCES" to be as follows:-
This invention relates to improvements upon the spinning and doubling frames,
the spindles and flyers of which formed the subject of an invention for which
I applied for Letters Patent N° 506 on the 3rd of January 1884.
Instead of the flyer therein shown and described I fix or form upon the upper
part of the revolving tube a very light metal cylinder or cup open at the top and
provided with a pair of short light legs formed with curls similar to the curls of
the said flyer. The object of this construction is to prevent the flyer legs from
expanding by the centrifugal action and coming into contact with each other in
the frame when driven at a high speed.
In order to fix the legs to the cylinder or cup I provide at the upper edge of the
same an external flange through which I bore holes for the reception of the said
legs, the lower ends of which I then solder to the outside of the cup and the legs
are then held by the flange to the cup.
This cylinder or cup may be cast in one piece or made of sheet metal.
When made of sheet metal I prefer to corrugate the same so that when bent
round the upper part of the cylinder or cup is corrugated circumferentially and
this serves instead of the flange, and also strengthens the said cylinder or cup.
The latter may also be cast to the revolving tube to which also the wharve
is cast.
It is evident that the wharve cannot be passed through the upper bearing of the
tube when constructed as shown on the drawing accompanying the Complete
Specification filed in pursuance of the above application. On this account therefore
I form a slot for each spindle in the upper fixed rail marked i on the said drawing
and I fix or form one part of the bearing in this slot, and I then slide a step into
the open slot and fix it to the rail in any convenient manner thus forming a readily
removable bearing which will allow of the insertion of the revolving tube.
Dated this 10th day of January 1885.

page_text: Improvements in Apparatus for Spinning and Doubling Cotton
and other Fibrous Substances.
I THOMAS ASHWORTH of Woodlands Davyhulme near Manchester in the County
of Lancaster Cotton Spinner do hereby declare the nature of my invention for
"IMPROVEMENTS IN APPARATUS FOR SPINNING AND DOUBLING COTTON AND OTHER
FIBROUS SUBSTANCES" and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
This invention relates to improvements upon spinning and doubling frames and
upon the spindles and flyers thereof which formed the subject of an invention for
which Letters Patent have been granted to me bearing date the 3rd day of
January 1884, Nº 506.
The construction and application of the various improvements which form the
subject of the present invention will be readily understood upon reference to the
drawings hereto annexed and the following explanation thereof.
Fig. 1. is an elevation of the flyer, flyer tube and wharve detached from the dead
spindle. Figs. 2. and 3 are detached plan views illustrating the method of passing
the flyer tube through the top spindle rail, and Fig. 4. is an elevation (partly in
section) of the whole apparatus complete. a, a is the dead spindle which is
mounted in and carried by the movable rail b, b and is fitted with the same
devices for carrying the bobbin d, d as are described in my former Specification
above referred to. I also employ the long tubular fixed collar m m and the
revolving flyer tube h, h carrying the wharve k, k, but instead of the flyer therein
described and shown I fix upon the upper part of the revolving tube h, h a very
light metal cylinder or cup g, g open at the top and provided with either one, or
two short light legs, formed with curls similar to the curls of the said flyer.
I prefer however to employ only one of these short legs and to balance the same
by a piece of solder or other metal g' fixed on the opposite side of the cylinder or
cup g, g and I find it preferable to make the curls of two separate pieces of
wire g', g² bent or curled in the form shown at Figs. 1 and 4.
The object of making the flyer g, g in the cylindrical or cup-like form is to
prevent the flyer legs from expanding by the centrifugal action and coming into
contact with each other in the frame when driven at a very high speed.
In order to fix the wires or curls g², g² to the cylinder or cup g I provide at the
upper edge of the said cup an external flange g³ through which I bore holes for the
reception of the wires, the lower ends of which I then solder to the outside of
the cup and the wires or curls are thus held firmly.
The cylinder or cup g may be cast in one piece or made of sheet metal and the
flange may be either cast there with or soldered or brazed thereto.
I prefer however to make the cup of sheet steel and to corrugate the same along
the upper edge as shown at Fig. 4. so that (when bent round into a cylindrical
form) the upper part of the cylinder or cup is corrugated circumferentially and
this corrugation serves instead of the flange and also stiffens or strengthens the
said cylinder or cup.

page_text: The top of the bush 1, is made, as before, in the form of an oil cup having a
cover, and in order to prevent the oil from rising up inside the revolving flyer
tube h, h I perforate the latter with holes *, * to allow the oil to pass from the
inside of the tube back again into the oil cup.
It is evident that the wharve k, k cannot be passed through the upper bearing
of the flyer tube h, h in the top rail i ż when constructed as shown on the drawings
of my former Specification above referred to, and for this reason I form a slot in
the rail i, i, for each spindle as shown at Fig. 2 and I fix or form one part of the
bearing in this slot, and I then slide a step o, o into the open slot and fix it to the
rail i, i by means of a screw or in any other convenient manner, thus forming a
readily removable bearing which will allow of the insertion of the revolving
tube h, h and wharve k, k; or I bore out a hole in the rail i, i large enough to allow
the wharve k, k, to pass through and I then fill in this hole with a step or
bush o¹, o' made in two pieces as shown at Figs. 3. and 4 fixing the same with a
screw o; or I sometimes divide the rail i, i in two parts longitudinally through the
centre line of the spindles, one side of each tube bearing in one half of the rail, and
the other side in the other half; the front half of the rail being attached by screws
or otherwise to the other or fixed half thereof after the revolving tubes h, h have
been introduced or placed in position.
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
•
First. The combination with the revolving flyer tube h, h of a cylinder or
cup g, g with a flange at its upper edge and one or two short legs or curls fixed in
such flange substantially as shown and described.
Secondly. The method of making the cylinder or cup and its flange from one
piece of sheet steel or other suitable metal by corrugating one edge thereof either
before or after bending the same into a cylindrical form substantially as shown and
described.
Thirdly. The method shown and described of making and fixing the short legs
substantially as shown and described.
Fourthly. The means of introducing and fixing the revolving flyer tubes h, h in
the top rail i, i substantially as shown and described.
