IMPROVEMENTS IN THE CON- STRUCTION OF BOBBINS AND SPOOLS."
Year: 1877

page_text: LETTERS PATENT to John Sidney Crowley, of Manchester, in the County of
Lancaster, Engineer, for the Invention of "IMPROVEMENTS IN THE CON-
STRUCTION OF BOBBINS AND SPOOLS."
PROVISIONAL SPECIFICATION left by the said John Henry Crowley at the
Office of the Commissioners of Patents on the 16th November 1877.
JOHN SIDNEY CROWLEY, of Manchester, in the County of Lancaster, Engineer.
"IMPROVEMENTS IN THE CONSTRUCTION OF BOBBINS AND SPOOLS."
My Invention consists in a combined metal ferrule with a projection or projections,
the ferrule being attached to the bobbin or spool to prevent the splitting of the
same when made of wood, and the projection or projections fitting into a recess or
recesses in the flange of the driving pinion, whereby the pinion and the bobbin or
spool are carried round together.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Sidney Crowley in the Great Seal Patent Office on the 8th
May 1878.
JOHN SIDNEY CROWLEY, of Manchester, in the County of Lancaster, Engineer.
"IMPROVEMENTS IN THE CONSTRUCTION OF BOBBINS AND SPOOLS."
My Invention consists in an improved metal ferrule with a projection or
projections, the ferrule being attached to the bobbin or spool to prevent the splitting
of the same when made of wood, and the projection or projections fitting into a
recess or recesses in the flange of the driving pinion, or between the lug or lugs on
the said flange, whereby the pinion and the bobbin or spool are carried round
together.
And in order that my Invention may be fully understood and readily carried into
operation, I will proceed to describe the accompanying Sheet of Drawings, in
which,
Fig. 1 is a section of my improved wooden bobbin or spool with my improved
metallic ferrule attached thereto.
Fig. 2 is a side view of the ferrule; Fig. 3, a plan of the same looking from
above; and Fig. 4, a plan looking from below.
I wish to observe here that I prefer to make the ferrules of malleable cast iron,
but they may be made of brass or other suitable metal.
The bobbin a is provided with a collar b near its lower end; under the collar is a
V shaped recess c, and the end of the bobbin is plain, no slots being required for
carrying the bobbin round. The ferrule & fits on the lower end of the bobbin a,
and the upper edge of the ferrule is serrated, as shewn in Figs. 2 and 3. The lower
part of the ferrule provided with notches e, as shewn in Fig. 4, which fit on the
lugs f of the driving pinion g, shewn in Figs. 1 and 5, for carrying the bobbin round,
in some cases a single lug ƒ may be used.
At the inside of the ferrule are one or more small midfeathers h, see Fig. 3, and
when the ferrule is being forced on the end of the bobbin these midfeathers enter
into the wood, the object being to prevent the ferrule turning round on the babbin
if the wood shrinks.
.
When the ferrule has been forced on the bobbin it is secured by bending the
serrated edge of the ferrule over and into the V shaped recess e in the bobbin; this
is effected in a lathe by means of guide and milling rollers, or in any other con-
venient manner.
The object of the collar b at the lower end of the bobbin a is to prevent the
presser finger of the flyer and the roving from coming in contact with the ferrule.
By thus constructing the ferrule and securing it to the wood bobbin I dispense with
the slots which hitherto have been cut in the end of the wood bobbins for carrying
the bobbins round with the driving pinions, and thus effectually prevent the splitting
of the wood bobbins.
Figs. 6 and 7 represent another of my improved ferrules, and Figs. 8 and 9
represent the driving pinion for imparting motion to the same; in these views I
have shewn two studs fprojecting from the ferrule taking into holes in the flange of
the driving pinion g.
Figs. 10 and 11 represent another modification of my improved ferrule with two
studs taking into slots in the flange of the driving pinion, shewn in Figs. 12
and 13.
Having thus stated the nature of my Invention and described several nodes of
performing the same, I wish it to be distinctly understood that I do not intend to
limit myself to the details given, as the same may be varied or modified, and that
I claim,—
First. The improved construction of metallic ferrules for bobbins or spools, as
shewn and described.

page_text: Secondly. Dispensing with the slots in the ends of wood bobbins or spools when
used in combination with metal ferrules, as described.
And, Thirdly. The collar near the end of the wood bobbin to prevent the yarn
or the presser flyer coming in contact with the metal ferrule, as shewn and
described.
In witness whereof, I, the said John Sidney Crowley, have hereunto set my
hand and seal, this Fourth day of May, One thousand eight hundred, and
seventy-eight.
JOHN SIDNEY CROWLEY. (L.S.)
