page_text: 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 THE CONSTRUCTION OF BOBBINS, TUBES OR SPOOLS
CHIEFLY USED IN THE FIRST PROCESSES OF COTTON SPINNING WITH MACHINERY OR
APPLIANCES FOR FORMING AND MANUFACTURING THE SAME to be as follows :-
"
A hoop, ferrule or bush formed from tinned steel plate, brass, or other sheet metal
is made thoroughly secure on the exterior or interior of the ends of the bobbins,
tubes or spools and considerably strengthens them by the following method―The
hoop ferrule or bush is first shaped or pressed by the usual means to suit the ends
of the bobbins which have been previously slotted to receive the driving stud.
By novel appliances the slots in the ferrules (usually four in number to correspond
with the bobbin) are simultaneously or otherwise cut, stamped or pressed, and the
edges forced against the sides of the slots at right angles to the circumference.
These edges impart a considerably increased strength to the bobbin and hoop,
effectually prevent the ferrule or bush from twisting out of position and thus
greatly add to the durability and service of the bobbin, tube or spool.
The hereinbefore mentioned novel appliances are as follows:-A conical face-
plate is arranged to carry four tool holders in grooves at angles to the ferrule which
is placed on the end of a spindle for piercing. Four punches are secured to the
end of the spindle and touch opposite points inside the ferrule. The tools are
shaped to act as dies, fitting the punches, and are moved simultaneously towards
the centre by means of a cam acting on pins secured to the underside of the
holders and passing through openings in the face plate. The cam is driven by a
worm and wheel

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 THE CONSTRUCTION OF BOBBINS, TUBES OR SPOOLS
CHIEFLY USED IN THE FIRST PROCESSES OF COTTON SPINNING WITH MACHINERY OR
APPLIANCES FOR FORMING AND MANUFACTURING THE SAME, and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
.
A hoop ferrule or bush formed from tinned steel plate, brass, or other sheet metal
is made thoroughly secure on the exterior of the ends of the bobbins, tubes or
spools, and considerably strengthens them by the following method.
The hoop, ferrule, or bush is first shaped or pressed by the usual means to suit
the ends of the bobbins which have been previously slotted to receive the driving
stud. By novel appliances the slots in the ferrules (usually four in number to
correspond with the bobbins) are simultaneously or otherwise cut, stamped or
pressed, and their edges forced against the sides of the slots at right angles to the
circumference.
These edges impart a considerably increased strength to the bobbin and hoop,
effectually prevent the ferrule or bush from twisting out of position, and thus
greatly add to the durability and service of the bobbin tube or spool.
The herein before mentioned novel appliances are as follows:-A conical face
plate is arranged to carry four toolholders in grooves at angles to the ferrule which
is placed on the end of a spindle for piercing.
Four punches are secured to the end of the spindle and touch opposite points
inside the ferrule. The tools are shaped to act as dies, fitting the punches, and are
moved simultaneously towards the centre by means of a cam acting on pins secured
to the underside of the holders and passing through openings in the faceplate. The
cam is driven by a worm and wheel.
Such being the nature and object of my said Invention the following is a
complete description of same reference being had to the accompanying drawings
forming a part of this specification; in which:-
Fig. 1. is a front elevation partly in section of the improved appliances con-
structed according to this invention.
Fig. 2. is a side elevation of Fig. 1. also partly in section.
Fig. 3. (sheet 2) is a front elevation shewing the principal parts, drawn to an
enlarged scale.
Fig. 4 is a side elevation of Fig. 3 partly in section.
The improved hoops or ferrules are fully illustrated on Sheet 4 of the drawings.
At 1 is a gantry on which is the bracket or standard 2, 3 and 4 are fast and loose

page_text: pulleys, 5 is the driven shaft, on which is a worm gearing with and driving the
worm wheel 6, thereby rotating the shaft 7 on which is a cam or eccentric plate 8
which at each revolution acts upon the anti-friction rollers 9 carried on studs 10,
the latter being attached to the holders 11 of the tool 12, the tool being held in
position by means of the screws 13.
When the cam 8 revolves its prominent surfaces act upon the runners 9, thereby
causing the several tools 12 to move inwards, their ends converging upon the central
rest 14, whilst their cutting and shaping ends shewn by enlarged views at Sheet 1
act upon the hoop or ferrule of sheet metal mounted upon the die 17 carried by
the spindle 18 of the loose head 19, the hoop or ferrule to be operated upon is first
by an ordinary press, formed as at A sheet 4, the bottom is then punched out by
means of the four winged die B, producing the angular recesses d, d, d, d, in the
rim C, this cutting away at parts d is necessary otherwise there would remain too
much metal for the subsequent punching and folding operations, the hoop C is now
placed on the die 17 having four slots cut therein at equal distances of its diameter
and opposite the converging punches 12-12-12-12, and by the hand wheel 19
screwed close up to the corresponding and slotted centre 14 whereon the four tools
simultaneously converge and cut or punch out four slots in the hoop D.
Meanwhile the parts of the cam projecting and used for operating by closing or
converging the tools having passed the runners 9, the latter will enter corresponding
hollows or recesses formed in the edge of the cam 8 whereon the spiral springs 21
which being attached to the tool holders by rod 22 were distended, by the inward
movement of the tools are now free to contract, and thereby draw the several tools
12, 12, outwards upon their carrying and supporting face plate 23 to their original
or normal position whereon the tools 12 are to be removed and replaced by the
tools 15 (sheets 1 and 3 so formed as that the part 15° enters the slot d which it
expands and together with the shoulders 15b folds inwards the edges of the hoop
as shewn at E and 20.
Of course in practice the hoops will all be operated upon by the tool 12 before
changing to the tools 15. Fig. 4.
It will be understood that other number than four of such radial tools may be
employed according to the number of slots to be formed in the bobbins.
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;
Firstly. The improvements in the construction of bobbins, tubes, or spools, by
applying thereto and combining therewith metal ferrules, the edges of the slots
therein being turned at right angles thereto, as and for purpose herein fully
described and illustrated by drawings annexed.
Secondly. The cam plate tool holders, tools, and dies in combination, con-
structed, operated, and operating in manner herein fully described and illustrated
by the annexed drawings.
