the Invention of "IMPROVEMENTS IN THE CONSTRUCTION OF CONDENSER

led the 11th June 1878, and dated the 19th December 1877.
PROVISIONAL SPECIFICATION left by the said John Kay at the Office of
the Commissioners of Patents on the 19th December 1877.
JOHN KAY, of Rochdale, in the County of Lancaster. "IMPROVEMENTS IN THE
CONSTRUCTION OF 'CONDENSER SPOOLS' OR BOBBINS USED IN THE MANUFACTURE
OF WOOLLEN AND OTHER YARNS."
The object of this Invention is to attach the sheet metal heads of the bobbins to
the wooden barrels thereof in such a manner that they are not liable to become
loose, and generally to increase the durability and strength of the spools or bobbins.
In the first place I bore the wooden barrel through from end to end, and I
provide a square bolt of a sufficient length to pass through the whole, both ends of
the same being turned so as to form pins or axles, and one end having a fixed collar,
and the other a movable collar or nut screwed thereon.
I provide each end of the barrel with a metal cap and washer (cast in one piece),
the outside of the washer having a square projection to receive the sheet metal head
which has a square hole also, so that it cannot turn round. The washer also
prevents the liability of the sheet metal ends to become dented and pressed into
the wooden ends of the barrel. The caps are cast with a midfeather inside, which
prevents them from turning on the barrel.
The caps and washers being placed on the ends of the barrel, and the sheet, metal
heads being placed on the square projections outside the washers, the bolt is passed

page_text: through the whole, and secured by screwing on the loose collar a nut, and the spool
or bobbin is then complete. The bolt keeps the whole firmly together and prevents
warping of the barrel.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Kay in the Great Seal Patent Office on the 18th June 1878.

The object of this Invention is to attach the sheet metal heads of the bobbins or
spools (used for condensers and piecing machines) to the wooden barrels thereof
in such a manner that they are not liable to become loose, and generally to
increase the durability and strength of the spools or bobbins.
Such being the nature and object of my said Invention, I will now proceed to
describe in detail the manner in which the same is to be or may be performed or
carried into practical effect, and in order that the same may be clearly understood
I have annexed hereunto a Sheet of Drawings illustrative thereof (made about two-
thirds the actual size), and have marked the same with figures and letters of
reference, corresponding with those in the following explanation thereof.
In the first place I bore the wooden barrel a, a, (Fig. 1) through from end to end,
and I provide a square or partly square bolt b, b, (Fig. 5) of a sufficient length to
pass through the whole, both ends of the sanie being rounded so as to form pins
or axles b', b', one end having a fixed collar or flange c, c, and the other a movable
collar or nut d, d, screwed thereon (see face view and section, Fig. 6); or the bolt
may be made triangular or of any other suitable section so as to prevent its
turning.
provide each end of the wooden barrel a, a, with a metal ferrule and washer,
cast in one piece so as to form a cap e, e, the outside face of the washer having a
square or other suitable projection e' to receive the sheet metal head f, f, (Fig. 7),
which has a corresponding hole in or near the centre, so that it cannot turn round.
The washers also prevent the liability of the sheet metal heads f, f, to become
dented and pressed into the wooden ends of the barrel a, a. The caps e, e, are
cast with an internal midfeather e", e", (see inside view, Fig. 3, and section, Fig. 4),
which prevents them from turning on the barrel a, a.
The caps e, e, being placed on the ends of the barrel a, a, and the sheet metal
heads, being placed on the square projections e¹, e¹, outside the caps or washers 6, 6,
the bolt b, b, is passed through the whole and secured by screwing on the loose
collar or nut d, d, and the spool or bobbin is then complete, as seen at Fig. 8. The
bolt b, b, and nut d, d, keep the whole firmly together and prevent the warping of
the wooden barrel a, a.

page_text: It will be evident that condenser spools made according to this Invention will
be very much stronger and more durable than those made in the usual manner, and
that the ends will not be liable to become loose as heretofore.
Having now described the nature and object of my said Invention, together with
the manner in which the same is to be or may be performed or carried into practical
effect, I wish it to be understood that I claim as my Invention, the construction of
condenser spools or bobbins, substantially in the manner herein-before described and
represented on the Drawings annexed, and especially I claim the construction of the
metal cap e, e, with its socket projection e', e', and internal midfeather e¹, e", all
cast in one piece, substantially in the manner and for the purposes above set
forth.
In witness whereof, I, the said John Kay, have hereunto set my hand and
seal, this Fifth day of June, in the year of our Lord One thousand eight
hundred and seventy-eight.
JOHN KAY. (LS.)
