Improvements in Bobbins for Warping, Winding, and the like
Processes.
I, JOHN BRUCE SUTTON, of 19, Bristol Street, Hulme, Manchester, in the County
of Lancaster, Mill Furnisher, do hereby declare the nature of this invention to be
as follows:-
My said invention relates to an improved construction of composite bobbin
for use for warping winding and similar processes.
The barrel of the bobbin is of wood, the heads are formed from a disc of metal
which is dished or pressed by suitable tools so as to form a central hollow boss, of
such an internal diameter as to fit on the barrel.
The periphery of the bobbin head is turned up to form a flange to contain a
wire ring which is held in position by the flanged edge of the bobbin head being
turned over on the ring.
The bobbin head is secured to the barrel by one or more corrugations or inden-
tations made by suitable tools in or on the boss of the bobbin head after it has
been placed on the barrel. The making of such a corrugation or indentation will
produce a corresponding channel in the end of the barrel and thus secure the head.

Improvements in Bobbins for Warping, Winding, and the like
Processes.
I, JOHN BRUCE SUTTON, of 19, Bristol Street, Hulme, Manchester, in the County
of Lancaster, Mill Furnisher, do hereby declare the nature of this invention and
in what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
My said invention relates to an improved construction of composite bobbin
for use for warping winding and similar processes.
The barrel of the bobbin of wood or the like suitable material is provided with
heads formed from a disc of metal which is dished or pressed by suitable tools
so as to form a central hollow boss of sufficient depth and internal diameter as
to fit firmly on the barrel. The periphery of the bobbin head is turned up to form

page_text: a flange to contain a wire ring which is held in position by the flanged edge of the
bobbin head being turned over on the ring.
The bobbin head is secured to the barrel by one or more corrugations or inden-
tations made by suitable tools in or on the boss of the bobbin head after it has
been placed on the barrel. The making of such a corrugation or indentation will
produce a corresponding channel in the end of the barrel and thus secure the
head.
In order that my said invention may be more clearly understood I will describe
the same with reference to the accompanying drawing.
Fig. 1 is a sectional elevation of one end of a bobbin constructed in accordance
with this invention.
Figs. 2 and 3 are sectional elevations illustrating modifications of my said
invention to be hereinafter described.
Fig. 4 are sections of the composite parts of the head illustrated in Fig. 3.
The ends of the barrel a of the bobbin are preferably formed slightly less in
diameter than the rest of the barrel. The heads are formed from a dise of
metal which is dished or pressed by suitable tools so as to form a central hollow
boss c of sufficient depth and internal diameter to fit firmly on the barrel a.
In order to strengthen the bobbin head the periphery thereof is turned up
to form a flange or beading to contain a wire ring e of suitable section which is
held in position by the flanged edge of the bobbin head being turned over on the
wire ring e
The bobbin head is secured to the barrel by indentations f made by suitable
tools in or on the central boss of the bobbin head after it has been placed on the
barrel.
The making of such a corrugation or indentation will produce a
corresponding channel or depression in the end of the barrel a and thus secure
the head. In the form shown in Fig. I the boss is outside and forms a perforated
cap over the end of the barrel.
t
When it is desired to provide a relatively greater distance or space between
the bobbin heads while retaining the same total length of barrel I form the
central boss e as shown at Fig. 2 having the boss e pressed in the opposite direction
to Fig. 1. In this case the central or cap portion y of Fig. 1 is stamped or cut
away in order to allow the boss to be placed on the end of the barrel a to which
it is secured by indenting or forcing inwards the edge f into the barrel as shown.
Instead of the metal head being formed in one piece of metal I in some cases
build it up as described below with reference to Figs. 3 and 4.
C
The central boss e is dished or pressed from a plate of metal to the shape shown.
The edge el is turned up. so as to take into one of the corrugations of the lock-
ing plate g The latter is formed from a plate of metal and has its outer edge
flanged. Another flanged plate h is provided to complete the bobbin head and
contain the wire. In building up such a hobbin head the wire e (Fig. 4) is first
placed inside the flanged plate h. The boss is then applied. Next the corrugated
locking plate g is placed in position. The flange d is turned over the wire and
over the Hange of the plate as shown in Fig. 3. When placed on the barrel a
the whole is secured by corrugations or indentations f as hereinbefore described.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
L

1. The combination with the barrel of a bobbin of a head of sheet metal having
a boss formed integral therewith by dishing pressing or the like process substan- 5
tially as and for the purpose set forth and shown.
2. In a hobbin for warping winding and the like processes the combination with
a barrel of a metal head b having a central boss . indentations or corrugations f
for securing the same to the barrel, a flanged periphery and wire ring e sub-
stantially as and for the purpose set forth and shown with reference to Figs. 15
and of the accompanying drawing.

page_text: 3. The combination with the barrel of a bobbin of a sheet metal head having
a dished boss c flanged metal plates g and h and a contained wire e secured to the
barrel by corrugations or indentations substantially as set forth and described with
reference to Figs. 3 and 4 of the accompanying drawing.
