Improvements in or connected with Bobbins Used in Machines for
Winding Yarns, and other Bobbins having Heads or Flanges.
We, GEORGE PALEY, of Bank Top Mills, Preston, in the County of Lancaster,
Cotton Spinner and Manufacturer, and JAMES ANDERTON SUTCLIFFE, of Globe
Works, Blackburn, in the same county, Sheet Metal Engineer, do hereby declare
the nature of this invention to be as follows
The object of our invention is to provide the heads or flanges of winders' and
other bobbins with a buffer or cushioning device for preventing the said bobbin
heads or flanges from being broken or injured when thrown down on the floor or
the like. In carrying our invention into effect we make the bobbin head in a double
form that is to say with a circular sheet metal plate or annulus fast to the extremity
of the bobbin the said plate being formed near its outer edge with an inner short
tubular part having an upper and lower outwardly projecting flange-and with a
second (but movable) circular sheet metal plate or annulus with an inwardly turned
flange which occupies a position between the outwardly projecting flanges of the
short tubular part on the fast plate. Within the space formed between the two
plates are disposed one or more (preferably) spiral or convolute springs whose
distention holds the two plates apart from each other and the movable plate having
a telescopic movement on the tubular part of the fast plate the required buffer or
cushioning device is thus provided. Surrounding the tubular part of the fast plate
and occupying a position between the inwardly turned flange of the movable plate
and the opposite outwardly projecting flange of the fast plate we preferably employ
a wire spring or an elastic ring or washer which answers as an additional buffer or
cushion.

the required buffer or cushioning device is thus provided. Surrounding the tubular

we preferably employ a wire spring or an elastic ring or washer which answers as

In the accompanying drawings,
Fig. 1 is a side view of a winder's bobbin illustrating the nature of our said
invention the flanges or heads being shewn in section and the stem or body part in
elevation the latter being formed with spiral corrugations for strengthening
purposes. a is the corrugated sheet metal stem or body part of a winder's bobbin
enclosing or firmly grasping at each of its extremities a wooden end piece b. c is a
sheet metal annulus soldered fast to the stem a at d and having at its outer edge an
inwardly projecting flange e which occupies a position between the outwardly
projecting flanges and g of the short tubular part of the loose plate i. jjare
two of any desired number of open spiral springs which are held in position between
the circular plates c and i by means of indentations or paps k k. 1lare flat circular
plates or washers of sheet metal soldered to the inner faces of the plates c and i to
give additional strength or rigidity thereto. At the upper flange or bobbin head
of Fig. 1 m indicates a wire spring or elastic washer interposed between the
inwardly turned flange e of the fast plate c and the opposite outwardly projecting
flange g of the movable plate i to answer as an additional buffer or cushioning
medium if thought requisite.
Figs. 2 and are respectively side and plan views shewing a method of applying
bent flat springs n n (shewn partly in broken lines at Fig. 3) in lieu of spiral wire
springs as shewn at Fig. 1.
Figs. 4 and 5 are respectively side and plan views shewing the application of
elastic india-rubber balls o o for the purpose of our invention and
Figs. 6 and 7 are like views illustrating the application of a single spiral or
volute spring p instead of a number of open spiral springs shewn at and described
with reference to Fig. 1.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
In winders' or other bobbins having flanges or heads the use or employment of a
spring buffer or cushioning device in manner substantially as described and shewn
in the drawings for the purpose specified.
