Improvements in and in the Manufacture of Spools, Bobbins, or Reels.
I THOMAS BROCKLEHURST of 128 Fishergate Preston in the County of
Lancaster, Tailor and Woollen Draper do hereby declare the nature of this
invention to be as follows:-
This invention consists of two methods of producing the reels, the first by useing
the wood pulp or paper pulp, and the second by useing the manufactured paper or
paper cardboard.
The first method is as follows, a number of moulds of the reels are prepared of
the shape and size required and the pulp is taken in a liquid state, and poured into
the moulds. After being allowed to solidify and harden they are placed in an
oven heated to a temperature of about 180° F. and gradually dried, after which
they are ready for staining colouring and labeling.
The second method of producing the reels is by useing manufactured paper or
paper cardboard and is as follows. The cylender or tube of the reel is made by
taking a piece of thick paper or cardboard of the requisite size and shape and
rolling it round and joining the two edges together with gum a neck or shoulder
being made at each end of a quarter to half an inch long, this is fitted into the
ends of the reel hereafter described.
The ends of the reel consists of two pieces of thick paper or cardboard. The
outer one being a plain flat piece circular in form with a hole in the centre.
The inside piece is cut in a circular form with a hole in the centre large enough
to fit on the end of the tube or cylender firstly described, and by cutting out a piece
triangular in form the base of which is equal to one fourth of the outer edge of the
circle and by bringing the two ends together, I form the convex portion of the end
of the reel.
These two parts of the reel end are now put together and by gumming or
cementing the outer edges the end of the reel is completed.
These are now fitted on the tube or cylender by placeing the neck into the hole or
slot-in the convex side of the reel end and so completing the reel.
The ends of the reel may also be made in one solid piece from strong thick card-
board or paper and also from wood or paper pulp. A die or stamp of the end
of the reel, of the shape and size required, and the. cardboard or pulp is put
into the die or stamp and by means of presure pressed into the desired form.
These ends. of the reel are then fitted on to the cylender or tube and so completing
the reel.
By this improvement I claim to be able to make a complete spool, bobbin or reel
from wood pulp, paper pulp, or from manufactured paper or paper cardboard, at
about half the cost of the present method of turuing them from solid wood, and as
they would be less than half the weight of wood reels a considerable saving would
be effected in carrage.

Improvements in and in the Manufacture of Spools, Bobbins, or Reels.
I THOMAS BROCKLEHURST of 128 Fishergate Preston in the County of
Lancaster Tailor and Woollen Draper do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by. the following statement:-
The said invention consists of two methods of producing the reels. The first by
useing wood pulp or paper pulp and the second by useing manufactured paper or
cardboard or by combining the two methods in one."
I am aware that card or pasteboard has been previously used for this purpose
according to the method of manufacture described in the Specification of Letters
Patent granted to Frank Warth dated the Thirtieth day of September in the year
of our Lord 1878 and numbered 3857 but without practical success and this
invention is designed to provide means whereby the difficulties heretofore existing
may be obviated.
The first method is as follows. The pulp used may be the wood pulp of
commerce or pulp made from any kind of waste paper which I break up into
shreds and boil in water eight or ten hours, the whole mass being kept moving
until it is reduced to a pulp, at this stage of the process
prepare a mixture of
flour alum, and water, in the proportion of one pound of flour to two ounces of alum
and one gallon of water and this is boiled for one hour. I then add this paste to
the pulp before described the whole being well beaten and stirred together until it
becomes thoroughly mixed. It is now ready to be run into the moulds, which are
prepared of the size and shape of the reels required. After being allowed to
cool they are placed in an oven heated to a temperature of about 180° F.
and hardened. They are again placed in a die and by means of heat and
pressure are pressed into a perfect reel, which may now be stained to any colour
and labelled.
The second method of producing the reels is-by useing manufactured paper or
cardboard and is, as follows. I make a tube or cylinder by taking a piece of thick
paper or cardboard of the requisite shape and size (according to the size of the
reel required) and rolling it round and joining the two edges together with gum as
Figure 1 & 2.
I am aware that a tube or cylinder is not new in the attempts to make paper
and cardboard reels, but I claim that a tube or cylinder with a neck and shoulder at
each end as shown in Figure 4 b. to receive the ends of the reel is new, and prevents
the ends of the reel from moving out of their place and makes them firmer and
altogether a stronger reel is produced thereby.
The ends of the reel consists of two pieces of strong thick paper or card-
board. The outer one is represented by Figure 3. and has a hole in the centre E.
to enable the reel to revolve on a spindle. This part is also shown on Figure 4 d.
and d¹.
The inside piece is cut in a circular form Figure 5 with a hole in the centre large
enough to fit on to the neck at the end of the tube or cylinder b. Figure 4 and by
cutting out a piece triangular in form f. y. Figure 5 the base of which is sufficient
to form the convex shape of the end of the. reel.
.
The two ends, f.. and g. are then fastened together by being gummed and pressed
or by wire revits or pins and so produce the convex part of the end of the reel as
shown in Figures 7 and 8.
I also make the convex portion of the end of the reel from a circular piece of
cardboard as shown on Figure 6. This piece being placed under a die or stamp is
by means of heat and pressure pressed into the requisite form as shown on Figures 7
and 8.
The convex end of the reel is now placed on the neck of the cylinder Figure 4 b.

page_text: after being first gummed and fastened by pressure and heat, I secure the joint with
wire revits or pins.
The capping or outer piece Figure 3 is then gunimed on to the outer edges and
pressed on to the convex or inner part as shown on Figure 4 d.
I also complete the ends of the reel by first fastening the outer piece Figure 3.
and the convex or inner piece, Figures 7 and 8. together as before described and
then fitting them on to the neck of the tube or cylinder fastening them as before
described and so completing the reel.
I also make the reels partly of pulp, and partly of paper or cardboard that is to
say I make the tube or cylinder Figure 1 from cardboard as hereinbefore described
and I make the ends of the reel Figures 7 and 8. from pulp by the same process as
I make the complete reel as firstly described, the parts are then fastened together as
before mentioned completing the reel Figure 9.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same may be performed, I declare that what I
claim is-
First. That the cylinder or tube with a neck and shoulder as described in Fig. 1
is new and will answer the purpose for which ! claim.
Second. The making of spools, bobbins or reels from wood pulp or paper pulp
as specified.
Third. The formation of the convex portion of the ends of the reel as hereinbefore
specified and shown in Figures 7 & 8.
Fourth. The fastening on the ends of the reel by means of wire revits or pins as
hereinbefore specified.
Fifth. That a reel made with a hollow tube of cardboard Fig. 1 and solid ends
made of wood pulp or paper pulp Fig. 7 & 8. is a new invention and will answer
the purpose specified.
Sixth. That reels made from paper pulp or cardboard can be made much cheaper
and are much lighter in weight than those made by turning from solid wood,
effecting a great saving in cost and carriage.
Dated this 26th day of February 1892.
