Improvements in Spools or Bobbins, Chiefly Designed for
Spinning Machines.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co. Patent Agents
45 Southampton Buildings in the County of Middlesex do hereby declare the
nature of this invention to be as follows:-
This invention relates to a spool or bobbin for use more particularly in machines
relating to spinning, and the invention consists of covering and protecting the
edges of the heads of bobbins or spools with metal, all substantially as hereinafter
fully described.
The barrel, and the heads of the spool or bobbin are all constructed as usual in
spools or bobbins for machines relating to spinning and needing no particular
description herein except so far as the present invention is concerned.
On the edge of each head of the spool, is a sheet metal plate which extends
around on each side of the same a short distance and is preferably made of a metal
that can be spun around the edge of the head to cover it, in accordance with this
invention.
The metal for covering and protecting the edge of each head can be prepared in
any of the usual ways for spinning it on the head, preferably in the form of a flat
ring shape of the desired width, and then pressed up into shape and spun around
the edges in any of the usual and well known ways of spinning metal.
Each head of the spool is first prepared for receiving its metal covering by
making preferably a circumferential groove in its edge and preferably
rounding its corners and making grooves, in its sides and the metal is then placed
upon the edge of the head and at each side the metal is turned over cach round
corner and turned and its edges, pressed into its respective groove in the side of the
head after which the metal at its central part is pressed down into the circum-
ferential groove, and made to fit closely and firmly the edge of the head.
Or in some cases the circumferential groove is dispensed with and the edge of
the head made flat, but the metal is forced over the sides of the edge into the side
grooves as before, or if desired the metal may be forced around the edge of the
head and the edge portions of the strip into wider grooves, in the sides, and turned
back partially one side of the head which is the outside, being turned off more than
the other.
By protecting both sides of the edge of the head of the spool by metal and
having it bent round and secured in the side grooves, including the central
peripheral groove, the shape and form of the metal secures great strength to the
same and to such an extent that the spool head when made of wood can be made in
one piece, being much cheaper than when made of two pieces or thicknesses of wood
and glued together; it also prevents any splitting or breaking of the edge, or any
warping of the head; and with the edges of the metal projecting in the sides of the
head, the metal strip is the more firmly secured in place, advantages which are
very desirable in such spools.
Obviously this invention is applicable to spools for other purposes as well as for
the use herein particularly described.

Improvements in Spools or Bobbins, Chiefly. Designed-for
Spinning Machines.
I. HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co... Patent Agents,
45 Southampton Buildings, in the County of Middlesex, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :—
This invention relates to a spocl or bobbin for use more particularly in machines
relating to spinning and the said invention consists in covering and protecting the
edges of the heads of bobbins or spools with metal, all substantially as hereinafter
described.
In the accompanying drawing,
Figure 1 represents in side view, a spool or bobbin having this invention applied
thereto;
Figure 2 is a view of one end of a bobbin showing the head in section, and,
Figures 3 and 4 are detail sections of the spool-head hereinafter referred to.
A represents the barrel, and B B the heads, of a spool or bobbin, all constructed
as usual in spools or bobbins for machines relating to spinning and which therefore
needs no particular description, except so far as the present invention is concerned.
On the edge of cach head of the spool is a sheet metal plate C, which extends
around for a short distance on each side of the same and is preferably made of
a metal that can be spun around the edge of the head to cover it in accordance with
this invention. The metal for covering and protecting the edge of each head can
be prepared in any of the usual ways for spinning it on the head, preferably in the
form of a flat-ring shape of the desired width, and then pressed up into shape
and spun around the edges in any of the usual and well-known ways of spinning
metal.
Each head of the spool is first prepared for receiving its metal covering by
making, preferably, a circumferential groove D in its edge and preferably rounding
its corners a band making grooves de in its sides, as shown in Figure 2. The
metal is placed upon the edge of the head, and then at each side is turned over the
round corner, and each of its edges f g pressed into its respective groove de in the
sides of the head, after which the metal at its central part his pressed down into
the circumferential groove D, and made to fit closely and firmly the edge of the
head.
In Figure 3 the groove D is dispensed with and the edge of the head made flat;
but the metal is forced over the sides of the edge and its edges are forced into the
side grooves, as before.
In Figure 4 the metal is shown as forced around the edge of the head and the
edge portions of the strip into wider grooves in the sides and turned back partially,
as shown, one side of the head, which is the outside, being turned off more than
the other.
By protecting both sides of the edge of the head of the spool by metal and
having it bent round and secured in the side grooves, including the central
peripheral groove, the shape and form of the metal secures great strength to the
same and to such an extent that the spool head, when made of wood, can be made
in one piece, as shown, being much cheaper than when made of two pieces or
thicknesses of wood and glued together. It also prevents any splitting or breaking
of the edge or any warping of the head, and with the edges of the metal projecting
in the sides of the head the metal strip is the more firmly secured in place,
advantages which are very desirable in such spools.
Obviously this invention is applicable to spools for other purposes than that
above described.

page_text: Having now particularly described and ascertained the nature of the inven-
tion 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. A spool having the edge of one or each of its heads covered with a metal
strip which extends around the edge and a short distance on each side of the head
and each edge of the metal strip being bent inward and disposed in a groove in its
respective side, for the purpose specified.
Second. A spool having the edge of one or both of its heads covered with a metal
strip which extends around the edge and a short distance on each side of the head,
each edge of the metal strip being bent inward and disposed in a groove in its
respective side and its central portion depressed into a circumferential groove in
the edge of the head, for the purpose specified.
Dated this 30th day of April 1891.
