Year: 1867

page_text: LETTERS PATENT to William Bostock, of the Firm of Hollins and
Bostock, of Manchester, in the County of Lancaster, Commission Agent,
for the Invention of IMPROVEMENTS IN SPOOLS, REELS, OR BOBBINS, AND IN
THE METHOD OF MANUFACTURING THE SAME.".
PROVISIONAL SPECIFICATION left by the said William Bostock at the
Office of the Commissioners of Patents, with his Petition, on the 21st
August 1867.
I, WILLIAM BOSTOCK, of the Firm of Hollins and Bostock, of Manchester,
in the County of Lancaster, Commission Agent, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN SPOOLS, REELS, OR BOBBINS, AND IN
THE METHOD OF MANUFACTURING THE SAME," to be as follows:-
My Invention relates to the "spools, reels, or bobbins "
upon which thread.
composed of cotton, silk, flax, or other similar fibrous material is-wound, and
upon which the said thread is supplied to consumers to be employed in sewing

page_text: and the like uses. And the improvements have reference more particularly to
those spools which are required to be made of a moderate weight to suit
certain markets or for other reasons, my method of manufacturing the
description of spools last referred to being as follows, namely:-
In the case of spools the ends of which are formed separately from the
barrel, and of the same or a different material, and are afterwards attached to
the barrel, I remove a portion of the wood' from the centre of the barrel by
boring or other suitable means, so as to form a cylindrical hole through the
said barrel of larger diameter than is ordinarily made to suit the spindles of
the winding machines, the thickness of wood in the barrel after being bored
being sufficient only to give a suitable strength to the said barrel. The "ends"
I form of wood, bone, metal, or other suitable material by turning or other-
wise, forming an annular groove in one side of each "end" of a suitable size
to fit the end of the barrel, the said "ends" being otherwise formed to give a
suitable appearance to the spool and to enable the spools to be filled in the
winding machines in the usual manner. The said "ends" are attached to
the barrel by forcing the ends of the barrel into the annular grooves in the
said "ends" either with or without the application of glue or other cement,
washers of thin calico or other suitable material being interposed between the
barrel and the "ends". if preferred. I sometimes form the barrel of the spool
by winding paper or thin scalėboard around a "mandril" and connecting the
layers together by means of glue or other cement; the ends being applied
in the manner above described. I also sometimes finish the "ends" of spools
the barrels of which are made lighter than is usual in the manner herein-above
described by covering the said end with suitably formed dises of brass or
other metal, which are "closed over "the ends of the spool or otherwise
fastened thereto.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Bostock in the Great Seal Patent Office on the
20th February 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
BOSTOCK, of the Firm of Hollins and Bostock, of Manchester, in the County
of Lancaster, Commission Agent, send greeting..
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters,
Patent, bearing'date the Twenty-first day of, August; in the year of our Lord One

page_text: thousand eight hundred and sixty-seven, in the thirty-first year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the
said William Bostock, Her special license that I, the said William Bostock,
my executors, administrators, and assigns, or such others as I, the said
5 William Bostock, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
SPOOLS, REELS, OR BOBBINS, AND IN THE METHOD OF MANUFACTURING THE SAME,"
upon the condition (amongst others) that I, the said William Bostock, by
an instrument in writing under my hand and seal, should particularly
describe and ascertain the nature of the said Invention, and in what manner
the same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Bostock, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement and accompanying Drawings, that is to say :-
My Invention relates to the "spools, reels, or bobbins" upon which thread
composed of cotton, silk, flax, or other similar fibrous material is wound, and
upon which the said thread is supplied to consumers to be employed in sewing
and the like uses. And the improvements have reference more particularly to
those spools which are required to be made of a moderate weight to suit
certain markets or for other reasons, my method of manufacturing the
description of spools last referred to being as follows, namely:-
In the case of spools the ends of which are formed seperately from the
barrel, and of the same or a different material, and are afterwards attached to:
the barrel, I remove a portion of the wood from the centre of the barrel by
boring or other suitable means, so as to form a cylindrical hole through the
said barrel of larger diameter than is ordinarily made to suit the spindles
of the winding machines, the thickness of wood in the barrel after being bored
being sufficient only to give a suitable strength to the said barret. The "ends"
I form of wood, bone, metal, or other suitable material by turning or otherwise;
orming an annular groove in one side of each "end" of a suitable size to fit
he end of the barrel, the said "ends "being otherwise formed to give a
uitable appearance to the spool and to enable the spools- to-be filled in the

page_text: '
winding machines in the usual manner. The said ends are attached to
the barrel by forcing the ends; of the barrel into the annular grooves-in the.
said," ends "either with or without the application of glue; or other cement,
washers of thin calico or other suitable material being interposed between the
barrel, and the "ends" if preferred. I sometimes form the barrel of the spool
by winding paper or thin scale board around a "mandril," and connecting the
layers together by means of glue or other cement, the ends being applied in.
the manner above described. I also sometimes finish the ends of spools the
barrels of which are made lighter than is usual in the manner herein-above
described by covering the said ends with suitably formed discs of brass or
other metal, which are "closed over "the ends of the spool or.. other wise
fastened.

In order that the said Invention may be fully understood I have annexed
to this Specification two, Sheets of Drawings having letters of reference marked
thereupon, to which I will now refer.,
Fig. 1 represents a longitudinal section, and Fig. 2 a cross. section of an
improved spool; Fig. 3 shewing the same as when filled with thread. The
barrel or body of the spool marked a is in this example formed, by winding
paper upon amandril until a. sufficient thickness is obtained' to ensure the
requisite strength, a solution of glue or any other suitable cement being applied
between the folds of paper as the said paper is being wound upon the mandril,
or the cement may be, applied to one or both surfaces of the paper before the
winding of it upon the mandril is commenced.. The paper tube thus formed
may be of sufficient; length to form the barrel of one. spool.only, or may be
made of a length sufficient. to form the barrels of two or more spools. Thin
scale board "consisting of a thin slice of wood may be wound upon a mandril,
and treated in a similar manner, as above; described. The ends 6 of the spool,
one of which is shewn detached at Fig. 4, are in this example formed of bone,
an annular groove c. being, turned or otherwise formed in one side of each end,
-the two ends being fixed to the barrel by inserting the ends of the said barrel
in the annular grooves and cementing them therein by means of glue or other
suitable cement. The holes d, d, formed in the ends are made of a suitable
size to fit the spindles of the winding machines.

Fig. 5 represents a longitudinal section, and Fig. 6 a cross section of a spool
the barrel of which is formed from a solid piece of wood by boring and turning,
the size of the bore being greater than usual, so that the thickness of the
shell a of the barrel.is sufficient only to give the requisite strength. The ends
are similarly formed and attached as in the former example.

page_text: Tig. 7 represents a longitudinal section; and Fig. 8.a cross.section of a spool
having metal ends. In this example the body or barrel of the tube is shewn
as formed in manner as in Fig. 1, but it may be formed of wood as in Fig. 7.
The ends. b, b, are formed of brass or other suitable metal, and preferably by
stamping, suitable grooves to receive the ends of the barrell being formed in
the operation of stamping...
Fig. 9 is a side view of the finished spool last described; and Fig. 10, a
plan view of the end upon which a name, trade mark, or any suitable device
may be stamped if desired.
Fig. 11 is a longitudinal section of a spool of a larger size than those herein
previously described. The barrel a is formed as in the example shewn at
Fig. 1, but may be formed of wood, as shewn at Fig. 5. The ends b, b, are
formed of wood with annular grooves as in the other examples to receive the
ends of the barrel, the outside surfaces of the ends being covered with a thin
sheet of brass or other suitable metal as at e, e.
Fig. 12 is a section, and Fig. 18 a plan of a capped paper tube, being a
foundation upon which balls of thread are sometimes formed. The annular
shaped body fis formed in a similar manner to the barrel portion of the spool,
as described in reference to Fig. 1, one end of the said body being closed with
a disc g formed of the same or a similar material to the body.
Having now described the nature of my Invention, together with means
for carrying the same into practical effect, I wish it to be understood that
I do not confine myself to the precise forms of spools represented in the
Drawings attached, nor to the exact combination of materials as herein-above
described, but wish it to be understood that I claim,―
First. With respect to spools the barrels of which are formed of wood, and
of a large diameter as compared with the diameter of the ends, the boring of a
larger hole through the centre of the said barrels than is required to enable
the spools to be slipped on to the spindles of the present winding or spool
filling machines, the shell of the barrel being left of a sufficient thickness only
to give the requisite strength, ends made of wood, bone, metal, papier mache,
or other suitable material, and prepared to fit the above-named spindles, being
afterwards fixed to the said barrels.
Secondly. Forming the barrels of spools of paper, "scaleboard," or other
imilar material, in the manner herein-before described or in manner similar
hereto.
.
Thirdly. Forming an annular groove in the portions of wood, bone, metal,
apier-maché, or other material which are to form the ends of spools as or

page_text: nearly as shewn in the accompanying Drawings for the purpose herein-before
described.
In witness whereof, I, the said William Bostock, have hereunto set
my hand and seal, this Nineteenth day of February, in the year of
our Lord One thousand eight hundred and sixty-eight.
WILLIAM BOSTOCK.. (L.S.)
