Improvements in Flanged Bobbins.
We JOHN WILLIAM WILSON, and WALTER BENNETT WILSON, both of
Beevor Works, Barnsley in the County of York, Bobbin Manufacturers, do hereby
declare the nature of this invention to be as follows:-
This invention relates to flanged bobbins employed in various processes in the
manipulation of fibres, and for other uses, and consists of an improved means of
securing metallic hoops or bindings around the periphery of the flanges whereby
the latter are strengthened and protected from being splintered or broken, the
periphery also presents a smoother and cleaner surface in cases where a yarn fibre
or fabric being wound on or off the bobbin runs in contact with the periphery
thereof.
According to this invention I construct the bindings or hoops from a strip of
metal the two ends of which are formed each into a hook one turned under, and
the other turned over; these hooks being slightly narrower than the width of the

being bent round forins a hoop and the hooks engage with each other and are con-
solidated by means of pressure, and soldered which has the effect of making the
exterior of the hoop practically seamless, whilst the hook joint forms inside the
hoop a key rib or projection. The hoop is next to be stamped or pressed to
the curvature or outline of the periphery of the flange in which is cut a groove,
recess, or key bed and which receives the rib projection or key formed by the joint
at the inside of the hoop. The edge or edges of the hoop is or are next to be
pressed, rolled, milled or spun, closely down on the periphery and edges of the
Hange which is thus enclosed and encased by a practically seamless metallic covering,
and it will be seen that the surplus metal in the interior of the joint is utilized 30
as to form a key whereby, together with the key bed cut in the periphery of the
flange, the metallic covering is locked in position, and prevented from turning round
and in addition to the protection afforded to the bobbin the latter has a highly
improved appearance finish and value.
I do not limit my invention to the special means described for making the joint
so long as it is provided that the ends of the strip are brought to the inside, and a
projection key or locking device is made therefroin to engage with a recess or key
bed cut in the flange of the bobbins the key and the key bed so formed con-tituting
a locking device whereby the hoop is secured in position as described.

COMPLETE SPECIFICATION.
Improvements in Flanged Bobbins.
We JOHN WILLIAM WILSON, and WALTER BENNETT WILSON, both of
Beevor Works, Barnsley in the County of York, Bobbin Manufacturers, do
hereby declare the nature of this invention 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 flanged bobbins employed in various processes in the
manipulation of fibres, and for other uses, and consists of an improved means of

page_text: securing metallie hoops or bindings around the periphery of the flanges whereby
the latter are strengthened and protected from being splintered or broken, the
periphery also presents a smoother and cleaner surface in cases where a yarn fibre
or fabric being wound on or off, the bobbin runs in contact with the periphery
thereof.
According to this invention I construct the bindings or hoops from a strip of
metal the two ends of which are formed each into a hook one turned under, and the
other turned over; these hooks being slightly narrower than the width of the strip
by reason of the corners of each end of the strip being cut out. The strip being
bent round forms a hoop and the hooks engage with each other and are consolidated
by means of pressure, and soldered which has the effect of making the exterior of
the hoop practically seamless, whilst the hook joint forms inside the hoop a key rib
or projection. The hoop is next to be stamped or pressed to the curvature or
outline of the periphery of the flange in which is cut a groove, recess, or key bed,
which receives the rib projection or key formed by the joint at the inside of the
hoop. The edge or edges of the hoop is or are next to be pressed, rolled, milled or
spun, closely down on the periphery and edges of the flange which is thus enclosed
and encased by a practically seamless metallic covering, and it will be seen that the
surplus metal in the interior of the joint is utilized so as to form a key whereby,
together with the key bed cut in the periphery of the flange, the metallic
covering is locked in position, and prevented from turning round and in addition to
the protection afforded to the bobbin the latter has a highly improved appearance
finish and value.
I do not limit my invention to the special means described for making the joint
so long as it is provided that the ends of the strip are brought to the inside, and a
projection key or locking device is made therefrom to engage with a recess or key
bed cut in the flange of the bobbins the key, and the key bed so formed constituting
a locking device whereby the hoop is secured in position as described.
Such being the nature of the said invention the following is a complete
description of same reference being had to the accompanying drawings.
The several figures on Sheet 1, shew the metal strips, (preferably mild steel
turned or sheet brass) plan-edge-back and front views.
Fig. 1, Sheet 2, shews completed hoop.
Fig. 2, section of bobbin, flange, and of hoop.
Fig. 3, is an end view of flange of bobbin, hoop applied to flange-and hoop
suspended, for purpose hereinafter described.
At 1, 1 are blanks, their ends formed as at 2, 2, and afterwards bent to form of
the hooks 3, 3, which hooks engage with each other, and are next submitted to
pressure, forming a projecting rib or key piece, inside the ring or hoop, as shewn
at 4, the whole is next pressed, stamped, rolled, or spun, to the form shewn in Fig. 1.
It is next applied to the flange of the bobbin J, so that the rib or key 4, enters the
slot or key bed 6, cut or formed in the flange 5, the key 4 and key bed 6, effectively
lock the hoop on the said flange, so far as preventing the hoop turning or slipping
around or circumferentially. Next the outer edges 7, of the hoop, will be spun
down to and closely upon the flange 3, so as to fit and lie closely thereon, also the
edge 8 will if needed be spun or pressed closely to the flange, a little solder will be
applied at the outside of the joint at 9, so as to fill in any angle or recess at that
point, and provide a uniform and even exterior throughout the hoop.
་་
As the flanges 5 are applied and turned up to the finished size on the barrel 10,
and the hoops are afterwards applied, it is most convenient in this section of flange
to first pass the hoops over the barrel 10 and hang or suspend them on the
hooks 11, 11, until the flanges are turned down to the required size and form,
wherein the hoops are slipped onto the flanges 5, with the key and key bed engaging
as described, and then the spinning or pressing down the edges of the hoops
completes the operation.
The hoops may, by bending or compressing into an oblong or eliptical figure, be
slipped over the flanges 5, 5 from the outside, that is to say-after the turning of

page_text: the flanges is completed, but we prefer not to bend the hoops but to hanging or
suspending on the looks as shewn in Fig. 4.
Although we have described the application of our said invention to one form or
section of flange it must be understood that the said invention is applicable to any
section or form of flange the hoop being pressed, stamped, spun or otherwise
wrought to the required shape and its joints forming on the inside a projecting rib
or key piece to engage with a slot or key bed cut in the flange of the bobbin as
described.
Having thus fully described the nature, and particulars of this our said inven-
tion, we would have it understood, that we do not claim per se, the application of an
edging ring, or hoop, to the flanges of bobbins as we are aware such is not new but
what we do claim is :-
The improved flanged bobbins, comprising, jointed hoops, the joint forming an
interior projection or key, the flange of the bobbin having a key bed, as and for
purpose herein fully set forth, and illustrated by drawings annexed.
