IMPROVEMENTS IN BOBBINS EMPLOYED IN DRAWING, FINISHING, AND ROVING FRAMES
Year: 1881

page_text: LETTERS PATENT to John Clayton, of the Firm of C. and J. Clayton, Bobbin
Manufacturers, Bradford, in the County of York, for an Invention of
"IMPROVEMENTS IN BOBBINS EMPLOYED IN DRAWING, FINISHING, AND
ROVING FRAMES."
PROVISIONAL SPECIFICATION left by the said John Clayton at the Office
of the Commissioners of Patents on the 29th March 1881.
JOHN CLAYTON, of the Firm of C. and J. Clayton, Bobbin Manufacturers,
Bradford, in the County of York. "IMPROVEMENTS IN BOBBINS EMPLOYED IN
DRAWING, FINISHING, AND ROVING FRAMES."
The present plan of making bobbins employed in drawing, finishing, and roving
frames consists in making the heads in two parts, that is to say, fitting on the
body of the bobbin wooden circular flanges, on which are fitted glued and pegged
wooden disks; after a short usage of the bobbins (and especially if the bobbins
have been kept as usual in a lower room, and when required brought in the heated
preparing room) the heads of the bobbins begin to open, and the disks lift and
become loose, causing damaged bobbius, the heads often breaking, consequently
producing loss.
To prevent these defects I secure on the tops of the flanges of the bobbins
wooden disks made in segments and cross grained, which prevent the warping and
lifting of the disks from the flanges, although the disks are secured on the tops of
the flanges with glue; and to form strong joints and to prevent the separation of
the disks from the flanges I secure the disks by screws or with rivets, by which
means I produce strong bobbins having heads that will not warp, lift, open, or
break, and which will last a considerable time.

by the said John Clayton in the Great Seal Patent Office on the
24th September 1881.
JOHN CLAYTON, of the Firm of C. and J, Clayton, Bobbin Manufactures,
Bradford, in the County of York. "IMPROVEMENTS IN BOBBINS EMPLOYED IN
DRAWING, FINISHING, AND ROVING FRAMES."
The present method of making bobbins employed in drawing, finishing, and
roving frames consists in making the heads in two parts, that is to say, fitting on
the body of the bobbin wooden circular flanges, on which glued and pegged wooden
disks are fitted; after a short usage of the bobbins (and especially if the bobbins
have been kept as is usual in a lower room, and when required for use are brought
in the heated preparing room) the heads of the bobbins begin to open, and the
discs lift and become loose, causing damaged bobbins, the heads often breaking, and
consequently producing loss.
To prevent these defects I secure on the tops of the flanges of the bobbins
wooden disks made in segments and cross grained, so as to prevent the warping
and lifting of the disks from the flanges; the disks are secured on the tops of the
flanges with glue; but to form strong joints and to prevent the separation of the
disks from the flanges I secure the disks by screws or with rivets, by which means
I produce strong bobbins having heads that will not warp, lift, open, or break, and
which will last a considerable time.
In order to enable my improvements to be better understood, I will proceed to
describe the same by reference to the accompanying Drawing, in which Figure 1
represents a section of my improved bobbin, Figure 2 an elevation, and Figure 3
plan of the same.
A is the body of the bobbin made with flanges B, on which are fitted wooden
disks C made in segments, and by preference cross grained to prevent them warping
and lifting; the discs C are secured on the tops of the flanges B with glue; and
to form strong joints and prevent the separation of the disks from the flanges
screws D are secured in the disks and flanges, or I may employ rivets, by which
means I construct strong bobbins having heads that will not warp, lift, open, or
break, and which will last a considerable time.
Having thus described my Invention, and the best means I am acquainted
with for carrying the same into effect, I would have it understood that what I
claim is,―
The manufacture and use of bobbins employed in Drawing, finishing, and roving
frames, or of other such like bobbins made with heads, which are prevented from
lifting, opening, warping, or breaking by means of screws or rivets, substantially
as herein described and represented by the accompanying Drawing.
In witness whereof, I, the said John Clayton, have hereto set my band and
seal, this Nineteenth day of September, in the year of our Lord One
thousand eight hundred and eighty one.
Witness,
WALTER JAMES TURNER, C.E.,
Patent Agent,
