IMPROVEMENTS IN THE CONSTRUCTION OF BOBBINS
Year: 1877

page_text: LETTERS PATENT to Andrew Reid, of Dundee, in the County of Forfar,
North Britain, for the Invention of "IMPROVEMENTS IN THE CONSTRUCTION
OF BOBBINS."
Sealed the 17th May 1878, and dated the 26th November 1877.
PROVISIONAL SPECIFICATION left by the said Andrew Reid at. the Offic.
of the Commissioners of Patents on the 26th November 1877.
ANDREW REID, of Dundee, in the County of Forfar, North Britain. "IMPROVE-
MENTS IN THE CONSTRUCTION OF BOBBINS."
This Invention relates to such bobbins as have their ends or heads affixed to the
shank or body by pins passed through the said ends or heads from the sides thereof,
and partly into the ends of the shank or body, with the view of preventing the
warping and falling off of the said heads. In bobbins of this kind as hitherto con-
structed, the shank being of one diameter throughout does not afford a sufficient
hold for the said pins to prevent this falling off of the said heads.
Now according to this Invention the ends of the shanks, or those parts upon
which the heads are affixed, and through which the fastening pins pass, are formed
with enlargements, preferably meeting the shank in a gentle curve.
These enlarge-
ments are of sufficient size to receive the entire diameter of the pins (used as afore-
said in fastening the heads to the shank), and to leave sufficient of the material of
the said enlargements around the pins to hold the heads firmly in their places on
the shank should the said heads by warping or splitting incline to leave the said
shank.
The fastening pins may be either of wood or metal, and are driven through the
heads, by preference transversely to the grain of the wood of the said heads.

MENTS IN THE CONSTRUCTION OF BOBBINS."
"IMPROVE-
My said Invention relates to such bobbins as have their ends or heads affixed to
the shank or body by pins passed through the said ends or heads from the sides
thereof partly into the ends of the shank or body, with the view of preventing the
warping or splitting and consequent falling off of the said heads. In bobbins of
this kind as hitherto constructed, the shank being of one diameter throughout, does
not afford a sufficient hold for the said pins to prevent this warping or splitting and
falling off of the said heads, that is to say, the material of the shank at that part is
not sufficient to receive the entire diameter of the pins.
According to this Invention the ends of the shank, or those parts upon which the
heads are affixed and through which the fastening pins pass, are formed with enlarge-
ments, preferably meeting the shank in a gentle curve. These enlargements are
of sufficient size to receive the entire diameter of the pins (used as aforesaid in
fastening the heads to the shank), and to leave sufficient of the material of the
said enlargements around the pins to hold the heads firmly in their places on
the shank should the said heads by warping or splitting incline to leave the
said shank.
In the accompanying Drawings Figure 1 represents in plan, and Figure 2 in
elevation, a bobbin constructed according to my Invention; Figure 3 is a section
of one of the heads of the said bobbin and part of the shank drawn to a larger
scale.
The shank or body of the bobbin is marked A; the heads are marked B; and the
fastening pins are marked C. As will be seen more particularly by reference to
Figure 3, the ends of the shank A, or those parts upon which the heads are affixed,
are formed with enlargements a of sufficient size to receive the entire diameter of
the pins C, and to leave sufficient of the material of the said enlargements & around
the said pins C to give an increased hold of the said pins upon the shank. By this
construction the heads B are securely held upon the shank, and are not liable to
leave the said shank. The fastening pius C may be either of metal or of hard wood,
and are driven through the heads B, by preference transversely to the grain of the
wood of the said heads, as shewn in the plan, Figure 1, as the pins then have a
tendency to prevent the distortion of the said heads by warping.
Having now described and particularly ascertained the nature of my said Inven-
tion, and the system, mode, or manner in or under which the same is or may be
used or practically carried into effect, I would observe in conclusion that what
I consider to be novel and original, and therefore claim as the Invention secured
to me by the herein-before in part recited Letters Patent is, constructing such
bohbins as have their heads affixed to their shanks by means of pins, in the manner
herein-before described, and illustrated in the accompanying Drawings, that is to
say, forming the ends of the shank, or those parts upon which the heads are fixed,
with enlargements to receive the entire diameter of the fastening pins.
In witness whereof, I, the said Andrew Reid, have hereunto set my hand and
seal, this Sixteenth day of May, in the year of our Lord One thousand
sight hundurd and coventre night
ANDREW REID. (L.S.)
