MENTS IN THE CONSTRUCTION OF BOBBINS AND SPOOLS
Year: 1885

page_text: I JOHN SIDNEY CROWLEY, of Corporation Street, Manchester, in the County of
Lancaster, Engineer, do hereby declare the nature of said Invention for IMPROVE-
MENTS IN THE CONSTRUCTION OF BOBBINS AND SPOOLS, to be as follows:-
My present invention relates to the Invention for which Letters Patent were
granted to me on the 16th day of November 1877 N° 4287 and consists chiefly in
an improved metal ferrule for protecting the end of a bobbin or spool, which may
be of wood or other material, such improved ferrule being particularly applicable
to bobbins used in fine spinning.
I make my improved ferrule preferably of malleable cast iron, but brass or other
suitable metal may be employed, the upper edge of the ferrule may be serrated or
plain and the lower or bottom edge is turned over or flanged with one or more
(preferably six) slots cast or otherwise formed in the body of the ferrule and
extending through the flange.
I prefer to form a shoulder near the bottom end of the bobbin or spool and
I secure the ferrule to the bobbin by bending or turning down the edge of the
former over such shoulder, and, farther, I prefer to turn or shape the bottom end of
the bobbin or spool in such manner that it is flush with the turned over or flanged
surface of the ferrule and I cut or otherwise form slots in the end of the bobbin or
spool to correspond with the slots in the ferrule, the said slots fitting on to the lugs
of the driving pinion.
The bottom outer edge of the flanged ferrule being rounded off, there are no sharp
corners to come in contact with and injure other bobbins as with the metal ferrules
now in use.

I JOHN SIDNEY CROWLEY, of Corporation Street, Manchester, in the County of
Lancaster, Engineer, do hereby declare the nature of said Invention for IMPROVE-
MENTS IN THE CONSTRUCTION OF BOBBINS AND SPOOLS, and in what manner the
same is to be performed, to be particularly described and ascertained in and
by the following statement :-
My present Invention relates to the Invention for which Letters Patent were
granted to me on the 16th day of November 1877 N° 4287 and consists chiefly in
an improved metal ferrule for protecting the end of a bobbin or spool which may
be of wood or other material such improved ferrule being particularly applicable
to bobbins used in fine spinning.
I make my improved ferrule preferably of malleable cast iron but brass or other
suitable metal may be employed; the upper edge of the ferrule may be serrated or
plain and the lower or bottom edge is turned over or flanged with one or more
(preferably six) slots cast or otherwise formed in the body of the ferrule and
extending through the flange.
I prefer to form a shoulder near the bottom end of the bobbin or spool and
I secure the ferrule to the bobbin by bending or turning down the edge of the
former over such shoulder and, farther, I prefer to turn or shape the bottom end of
the bobbin or spool in such manner that it is flush with the turned over or flanged
surface of the ferrule and I cut or otherwise form slots in the end of the bobbin or
spool to correspond with the slots in the ferrule, the said slots fitting on to the lugs
of the driving pinion.
The bottom outer edge of the flanged ferrule being rounded off, there are no sharp
corners to come in contact with and injure other bobbins as with the metal ferrules
now in use.
And in order that my Invention may be fully understood and readily carried
into effect I will describe the accompanying sheet of Drawings, reference being had
to the figures and letters marked thereon.
Figure 1 is an elevation. Fig. 2 a similar view partly in section, and Fig. 3 a
plan of the bottom end of a bobbin fitted with my improved metal ferrule. Fig. 4
is a sectional elevation of a bobbin similarly fitted but with the lower end of the
wood finished flush with the outer lower surface of the flange of the ferrule. Figs. 5
and 6 are detailed views of a ferrule similar to that shown attached to the bobbins
in the preceding Figures and Figs. 7 and 8 are detailed views of an alternative
construction of my improved ferrule.
Similar letters refer to similar parts throughout the several views.
In these views.-a is the bobbin, b is the improved ferrule the upper edge b¹ of
which is shown plain in Figs. 1, 2, 4 and 6 and serrated in Fig. 8. This upper
edge b¹ being bent or turned down over the shoulder a¹ to secure the ferrule b in
position and the ferrule is or may be further secured by casting or forming fins or
mid feathers 6 (as shown in Figs. 5 and 6) in the interior of the ferrule. Six
slots b³ are cast or formed in the ferrule shown and corresponding slots are cut in
the bobbin but one or other number may be made as preferred.

page_text: In Fig. 2, the end of the bobbin does not extend down to the level of the lower
outer surface of the flange b* but in Fig. 4 the end of the bobbin is finished off flush
or level with the outer surface of the flange b' which is in every case rounded off
on the edge and lies flat on the end of the bobbin or spool.
My improved ferrules may be cast, stamped or made in any convenient manner.
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 combination with a bobbin or spool of the improved ferrule b constructed
and arranged substantially as herein described and as shown on the Drawings
annexed.
2. In a ferrule for bobbins or spools, the combination with the plain or serrated
edge of the rounded off flange 6 lying flat on the end of the bobbin or spool,
substantially as herein set forth for the purposes specified.
3. The combination with the improved ferrule herein shown and described of
one or more fins or mid feathers 6 for the purpose specified.
