IMPROVEMENTS IN BOBBINS
Year: 1872

page_text: LETTERS PATENT to Wolf Bash, Samuel Bash, and Gustav Bash, all
of Glasgow, in the County of Lanark, North Britain, for the
Invention of "IMPROVEMENTS IN BOBBINS."
Sealed the 21st June 1872, and dated the 6th January 1872.

page_text: diameter, those for forming the body being glued or cemented at the
outer edge or throughout, whilst those for forming the ends are glued or
cemented at the outer edge only.
In constructing the bobbins that portion of a tube constituting the
body is cut off of a length equal to the entire length of the bobbin to be
produced. The ends are constructed by cutting off from another tube
of the required size a piece of the requisite thickness, which is then
placed between the dies of a press, and by the pressure therein com-
pressed into the required shape. The hole in the end pieces being equal
in diameter to that of the tube constituting the body of the bobbin and
being placed thereon, the body and ends are fixed together by pressure,
and with or without glue or cement; and in order to fill up the ends of
the tube plugs of paper tube of the required diameter are cut off from
another tube and forced thereinto until the ends, terminations of the
body tube, and plug constitute a flush or level surface. If desired to
strengthen or stiffen the body of the bobbin so constructed a plug may
be forced down into the central part thereof. It is preferred that the
end plugs be made slightly conical, taper, or countersunk, in order to
effect a better holding together of the several parts.
In order to colour the bobbins the pulp of which the paper is made
may be coloured in any desired manner, or the bobbins may be painted,
stained, enamelled, varnished, or otherwise tinted, or the ends or exposed
surfaces of the bobbins may be covered with metal.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Wolf Bash, Samuel Bash, and Gustav Bash in 2
the Great Seal Patent Office on the 5th July 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WOLF
BASH, SAMUEL Bash, and Gustav Bash, all of Glasgow, in the'County
of Lanark, North Britain, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her 3
Letters Patent, bearing date the Sixth day of January, in the year of
our Lord One thousand eight hundred and seventy-two, in the 35th
year of Her reign, did, for Herself, Her heirs and successors, give and

page_text: grant unto us, the said Wolf Bash, Samuel Bash, and Gustav Bash,
Her special license that we, the said Wolf Bash, Samuel Bash, and
Gustav Bash, our executors, administrators, and assigns, or such others
as we, the said Wolf Bash, Samuel Bash, and Gustav Bash, our
executors, administrators, or 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 BOBBINS," upon the condition (amongst others) that
we, the said Wolf Bash, Samuel Bash, and Gustav Bash, by an instru-
ment in writing under our hands and scals, 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 we, the said Wolf Bash, Samuel Bash, and
Gustav Bash, do hereby declare the nature of our said Invention, and in
what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement, reference being had
to the accompanying Drawings, and to the letters and figures marked
thereon, that is to say :-
Our said Invention relates to improvements in bobbins constructed of
paper, pasteboard, cardboard, or other pulped material.
And in order that our said Invention may be properly understood
we now proceed more particularly to set forth the system, mode, or
manner in or under which the same is or may be used or practically
carried into effect, that is to say :-
On the Sheet of Drawings hereunto appended Figure 1 is a side
elevation; Figure 2, a vertical section; and Figure 3, a plan of a bobbin
constructed in accordance with this Invention; whilst Figures 4, 5, 6, 7,
and 8 are detailed views of the several parts or sections of which the
said bobbin is composed.
In carrying this Invention into practical effect the paper, pasteboard,
cardboard, or other pulped material is first rolled into tubes of the
required diameter and thickness, the tubes for forming the body a being
glued or cemented at the outer edge or throughout the whole body of

page_text: material, whilst the tubes for forming the ends are glued or cemented
at the outer edges only.
In constructing the bobbins according to the arrangement illustrated
at Figures 1, 2, 3, 4, 5, 6, 7, and 8, that portion of a tube constituting
the body a is cut off of a length equal to the entire length of the bobbin
to be produced, as shewn on the Drawings, and the ends bare con-
structed by cutting off from another tube of the required diameter and
thickness pieces of the requisite length, which are then placed between
the dies of a press and thereby compressed into the shape illustrated on
the Drawings. The hole & in the end pieces b, shewn more particularly
at Figure 6, is formed in diameter equal to that of the tube constituting
the body a of the bobbin, and the ends b after being placed on the
extremitics of the body a arc fixed thereto by pressure,
exerted in any
suitable manner, and with or without the aid of glue or cement. In
order to fill up the ends of the tube constituting the body a of the
bobbin plugs e of the required diameter and thickness are cut off from
another paper, pasteboard, or cardboard tube and compressed into the
requisite shape, after which they are forced into the ends of the tube a
until the ends, terminal of the body a, and plug e form a flush or even
surface, as shown on the Drawings. It is preferred to form the end
plugs e slightly conical, as shown at Figure 2 and in detail at Figure 7,
in order to effect a better holding together of the several parts; and in
order that the plugs e may with greater facility be forced into the ends
of the tube a, and also to cause the ends b to have a more secure hold on
the body picce a, it is found advantageous to cut or notch the said tube :
at the extremities, as shown at g, Figures 4 and 5 of the Drawings.
Under another modification, illustrated in vertical section at Figure 9
and in plan at Figure 10, the plugs e are formed with shoulders ≈ at
their outer extremities, as shown in vertical section at Figure 9 and in
detail at Figure 11, and the body tube a is terminated at a short
distance from each end of the bobbin, the remaining space between
the extremities of the tube a and the flush surfaces of the ends b of
the bobbin being filled up by the shoulders x of the plugs e.
Under the arrangement of bobbin illustrated in vertical section at
Figure 12 the end pieces are dispensed with, the tube forming the
body a when constructing the bobbin being placed between the
dics of a press and forced outwards at the ends, as shown, so that

page_text: the projecting portions c in conjunction with the plugs e constitute tho
ends of the bobbin.
If it is desired to strengthen or stiffen the bodies of bobbins con-
structed under either of the modifications hercin-before described and
shown on the Drawings, a plug, previous to inserting the cnd plugs e,
may be forced down into the central part of the body a, as shewn in
vertical section at 1, Figure 13.
In order to colour the bobbins constructed in accordance with this
Invention, the pulp of which the paper, pasteboard, or cardboard is made
may be coloured in any desired manner, or the bobbins themselves after
being constructed may be painted, stained, enamelled, varnished, or
otherwise tinted, or their ends or exposed surfaces may be covered with
metal.
Having now described and particularly ascertained the nature of our
said Invention, and several systems in or under which the same is or
may be used or carried out in practice, we would observe in conclusion
that we do not confine ourselves to the arrangement precisely as herein-
before described and shewn on the Drawings, but what we do consider
to be novel and original, and therefore claim as the Invention secured to
us by the herein-before in part recited Letters Patent is, constructing
bobbins of paper, pasteboard, cardboard, or other pulped material in
sections or pieces, and putting the same together, as herein-before
described and shewn on the Sheet of Drawings hereunto appended.
In witness whereof, we, the said Wolf Baslı, Samuel Bash, and
Gustav Bash, have hereunto set our hands and scals, this
Third day of July One thousand cight hundred and seventy-
