I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature of
this invention to be as follows:-
My invention relates to the manufacture of shuttles bobbins and spools of any stylo
or shape and consists in coating the exposed surfaces both exterior and interior with
a layer of Japan enamel, which is applied and baked thereon, in the manner familiar
to enamellers.
It is necessary that spools, bobbins and shuttles should have a firm, smooth surface;
hence it is usual to make them of hard wood; but such unprotected wooden surface is
apt to be cut by the yarn and to wear irregularly or to splinter, so that the bobbin or
shuttle becomes impaired or useless. Sometimes they are made of wood, covered with
inetal, and occasionally they have been made entirely of metal; but all such are
objectionable, because of the weight. The object of the present invention is to ensure
so smooth a surface that the yarn will not catch upon the spool, bobbin or shuttle in
unwinding. I obtain such a surface by my invention, as the Japan enamel, when
applied in its liquid state, is smooth and uniform and, when baked, the artificial heat
develops the composition into a peculiarly hard tenacious and durable substance of
admirable wearing qualities. The vulcanized enamel cannot be cut or worn by the
yarn, but continues firm and smooth, though long used. I am thus enabled to
make my shuttles, bobbins and spools of a cheap, light, wood, as the fibre is wholly
covered and protected, and yet to have a wearing surface equal to metal in smoothness
and durability, but without the weight of metal.

page_text: When wet yarn is used, as in the manufacture of woollen fabrics, the moisture is
apt to cause the wood to swell and the cop is consequently bound upon the spool or
bobbin thereby causing an unequal tension and in some instances breakage of tho
yarn. I avoid this difficulty by my improvement because the enamel is waterproof
and remains wholly unaffected my moisture of any kind.
Another disadvantage sometimes experienced in the use of the ordinary spools and
bobbins is that they take oil from the spindles upon which they are mounted and
become saturated with the oil. The result is that the yarn is stained and greased
and the cloth is damaged and rendered unsaleable. By my invention such difficulty
is avoided as the enamel is impervious to the oil.

Figure 8 shows in central longitudinal section a bobbin having my improvement.
In all the above Figures the coating of enamel is represented by a heavy black
line.
It is necessary that spools, bobbins and shuttles should have a firm smooth surface;
hence it usual to make them of hard wood; but such unprotected wooden surface is
apt to be cut by the yarn and to wear irregularly or to splinter so that the bobbin
or shuttle becomes impaired or useless. Sometimes they are made of wood, covered
with metal and occasionally they have been made entirely of metal; but all such are
objectionable, because of the weight. The object of the present invention is to
ensure so smooth a surface that the yarn will not catch upon the spool, bobbin or
shuttle in unwinding.
I obtain such a surface by my invention as the Japan enamel when applied in its
liquid state, is smooth and uniform and, when baked, the artificial heat develops the
composition into a peculiarly hard, tenacious and durable substance of admirable
wearing qualities. The vulcanized enamel cannot be cut or worn by the yarn, but
continues firm and smooth, though long used. I am thus enabled to make my
shuttles, bobbins and spools of a cheap, light wood, as the fibre is wholly covered and

durability, but without the weight of metal.

Another disadvantage sometimes experienced in the use of the ordinary spools
and bobbins is, that they take oil from the spindles upon which they are mounted
and become saturated with the oil. The result is, that the yarn is stained and

page_text: greased and the cloth is damaged and rendered unsaleable. By my invention such
difficulty is avoided as the enamel is impervious to the oil.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed as communicated to me by my
foreign correspondent I declare that what I claim is ;
First. The coating of shuttles, bobbins or spools with enamel, for the purposes
specified.
Second. A shuttle bobbin or spool having its surface covered with a japanning
liquid, which is developed and vulcanized by artificial heat, substantially as specified.
