I JOHN WILLIAM WILSON of Beevor Works in Barnsley in the County of
York Bobbin Manufacturer and Timber Merchant do hereby declare the nature of
my invention for IMPROVEMENTS IN BOBBINS AND SPOOLS USED IN SPINNING
DOUBLING AND TWISTING FIBROUS MATERIALS. to be as follows:-
A Metal Shield or Protector constructed and applied to the bottom flange or end
of the Bobbin or Spool and which flange is slotted bored or recessed to receive the
driving Stud fixed on the Spindle or Tube whereby the Bobbin is made to revolve
on the Spindle or Tube to perform the Work assigned to it. These Shields or
Protectors are formed from Sheet Brass Copper Tin Steel or other suitable Sheet
Metal. When applied they considerably strengthen and preserve the Bobbin
Flange and effectually prevent the Driving Stud wearing the Slot Bore or Recess
and thus destroying the practical use of the Wood or other Bobbin.

I JOHN WILLIAM WILSON of Beevor Works, Barnsley in the County of York,
Bobbin Manufacturer and Timber Merchant do hereby declare the nature of my
invention for IMPROVEMENTS IN BOBBINS AND SPOOLS USED IN SPINNING DOUBLING
AND TWISTING FIBROUS MATERIALS and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
A metal shield or protector constructed and applied to the bottom flange end or
ends of the bobbin or spool and which flange or end is slotted bored or recessed to
receive the driving stud fixed on the spindle or tube whereby the bobbin is made
to revolve on the spindle or tube to perform the work assigned to it. These shields
or protectors are formed from sheet brass, tin, steel or other suitable sheet or cast
metal and when applied they considerably strengthen and preserve the bobbin
flange or end and effectually prevent the driving stud wearing the slot bore or
recess and thus destroying the practical use of the wood or other bobbin.
For the purpose of making the nature of my invention clear and intelligible
I append a sheet of drawings.
A piece of brass or other sheet metal is stamped, pressed or shaped into the form
indicated by Figs. 1. 2. & 3. which are respectively the elevation section and plan.
The rim is flanged at a for a portion or the whole of its outside circumference. In
the rim two or more recesses b. are formed the bottoms of which are slightly raised
in order that when in position in the bobbin and pressure is applied they may be
made to take the shape of a dovetail as at e in Fig. 4. The centre is pierced with
an opening c to allow of the protector being slipped over the spindle or tube and
the inner circumference is also flanged forming a bush inside the bobbin.
Fig. 4 is a drawing of a cap spinning and twisting bobbiu used for spinning and
twisting fibrous materials and explains my method of applying the protector or
shield. The flange of the bobbin is slotted or recessed to receive the stud on the
driving spindle or tube which imparts motion to the bobbin. The bottom of the
recess is made larger than the top in the form of a dovetail e and the protector is
pressed into this space. The bobbin is grooved to receive the flange a, the dovetail
and flange effectually preventing the shield separating from the bobbin. The sides
of the recesses may also be made parallel as at d Figs. 1 and 2, and driven tightly
into the bobbin or spool.
A ring doubler bobbin or spool is represented in Fig. 5. In this case the flange
of the protector is on the outside of the bobbin or spool flange.
In section and plan Fig. 6 I apply my invention to another flanged bobbin. The
sides dare turned over the edges of the slots in the bobbin and the flange is carried
entirely round the protector or shield and forced into a groove formed in the flange
of the bobbin as shewn at a.
Fig. 7 is a varied form of the protector. The principle of the dovetail is retained
but the shape of the surface may be square, oblong or of other form and flanged at
the sides as shewn in the sectional view, at a.

page_text: Figs. 8 and 9 are drawings of press slubbing intermediate or roving bobbins or
spools with slots for the reception of the stud or studs on the bobbin wheel for the
preservation of which slots my invention may be applied with benefit.
I prefer the protectors or shields made of sheet brass or steel but they may be
of cast metal, malleable iron or of other material provided they are of the form
previously described.
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
°
1 The strengthening and protecting of the slot or recess which receives the
stud fixed on the spindle or tube for driving the bobbin or spool used in spinning
and doubling machinery by the application of a metal or other shield hereinbefore
described and shown in the drawings attached.
2nd A protector or shield of a novel form and applied without the aid of screws,
rivets nails or other similar methods of fastening in the manner shewn effectually
preventing its separation from the bobbin or spool.
3rd The shield being of simple form and dovetailed makes it thoroughly secure
and can be used with the greatest advantage and economy in the bobbins tubes or
spools for spinning or other purposes.
