I, THOMAS MALLINSON, of 125, St. Paul's Road, Bow, in the County of Middlesex,
Wire drawer, do hereby declare the nature of this invention to be as follows :—
This invention relates to apparatus for tinning fine wire used for various purposes.
The process of tinning such wire is usually carried on in a tank or bath containing
the tin which is kept in a molten state by the heat of a furnace, the sides of the tank
or bath, in order to protect the workman from the heat, being euclosed within the
brickwork of which the furnace is composed.
The wire is fed from reels or swifts whence it passes between pegs or guides through
a vessel containing the solution for preliminarily treating the wire; it then passes
over a mop or wiper for removing the superfluous solution; thence under a roller or
rollers in the tinning tank or bath; then through another mop or wiper being finally
smoothed or deprived of superfluous tin by being threaded through an elastic or
compressible bush in a chuck by which pressure is applied. The wire is then wound
onto drums or their equivalents by suitable machinery.
The hereinbefore described arrangement of furnace and tinning tank or bath has
been found to be objectionable on account of the large amount of space taken up by
the brickwork preventing the workman from standing near enough to the tank to
properly attend to the operation. Also the brickwork after a time becomes so hot that
it does not afford efficient protection, and, on account of the destructiveness of the
heat, it requires to be frequently repaired.
To obviate these objections I construct the furnace of metal and suitably connect it
the tank or bath and I provide a narrow air passage or jacket on each side of the
tank or bath or a coating of non-conducting material for preventing the heat from
causing inconvenience to the workman. I also provide a recess at the lower part of
the apparatus to allow room for the workman's feet and thereby enable him to stand
with ease close to the side of the apparatus.
Instead of employing reels of different sizes to suit the different sizes of coils of
wire as heretofore I construct them so that they can be reduced or enlarged in
diameter whereby I am enabled to use the same reels for coils of various sizes.

page_text: I dispense with the hereinbefore described guiding pegs as I find it more advantageous
to employ a flanged guide roller for each wire thereby assisting the passage of the
said wire and preventing it from stiffening.
In order to prevent the wet cotton forming the mop or wiper from being drawn
into the tinning bath and thereby causing accidents I form the mop container with a
flange having slots or recesses for the passage of the wire.
When required to remove the roller or rollers heretofore employed for conducting
the wire into the tinning bath for cleaning it or them or for other purposes it has been
necessary to stop the tinning operation to allow this to be done. According to my
improvements I obviate this objection by providing a separate guide for each wire,
any one or more of which guides can be removed and replaced independently of the
others without interrupting the tinning process with respect to the other wires.
In place of employing chucks as hitherto for smoothing the wire as it passes to the
drums and through which chucks the wires have to be threaded I provide a number
of presses each constructed with a recess in which the wiping material is placed; the
said recess being open to allow of the wire being placed therein; the required pressure
is given by means of an arrangement of worm and worm wheel in combination with
a quick acting screw.
By this means the compresser is approximately adjusted and withdrawn in a rapid
manner and greater pressure can be applied to the wire than heretofore.

page_text: Improvements in Apparatus for Use in the Manufacture of
Tinned Wire.
I, THOMAS MALLINSON, of 139, St. Paul's Road, Bow, in the County of Middlesex,
Wire drawer, do hereby declare the nature of this invention and in what manner
the same is to he perforined to be particularly described and ascertained in and by
the following statement :-
This invention relates to apparatus for tinning fine wire, used for various purposes.
The process of tinning such wire is usually carried on in a tank or bath containing
the tin which is kept in a molten state by the heat of a furnace, the sides of the tank
or bath, in order to protect the workman from the heat, being enclosed within the
brickwork of which the furnace is composed.
The wire is fed from reels or swifts whence it passes between pegs or guides
through a vessel containing the solution for preliminarily treating the wire; it then
passes over a mop or wiper for removing the superfluous solution; thence under a
roller or rollers in the tinning tank or bath; then through another mop or wiper being
finally smoothed or deprived of superfluous tin by being threaded through an elastic
or compressible bush in a chuck by which pressure is applied. The wire is then
wound onto drums or their equivalents by suitable machinery.
The hereinbefore described arrangement of furnace and tinning tank or bath has
been found to be objectionable on account of the large amount of space taken up by
the brickwork preventing the workman from standing near enough to the tank to
properly attend to the operation. Also the brickwork after a time becomes so hot
that it does not afford efficient protection, and, on account of the destructiveness of
the heat, it requires to be frequently repaired.
To obviate these objections I construct the furnace of metal and suitably connect
it to the tank or bath and I provide a narrow air passage or jacket on each side of
the tank or bath or a coating of non-conducting material for preventing the heat
from causing inconvenience to the workinan. I also provide a recess at the lower
part of the apparatus to allow room for the workman's feet and thereby enable him to
stand with caso close to the side of the apparatus.
Instead of employing reels or swifts of different sizes to suit the different sizes of
coils of wire as heretofore I construct them so that they can be reduced or enlarged
in diameter whereby I am enabled to use the same reels for coils of various sizes.
I dispense with the hereinbefore described guiding pegs as I find it more
advantageous to employ a flanged guido roller for each wire thereby assisting tho
passage of the said wire and preventing it from stiffening.
In order to prevent the wet cotton forming the mop or wiper from being drawn
into the tinning bath and thereby causing accidents I form the mop container with a
flange having slots or recesses for the passage of the wire.
When required to remove the roller or rollers heretofore employed for conducting
the wire into the tinning bath for cleaning it or them or for other purposes, it has
been necessary to stop the tinning operation to allow this to be done. According to
my improvements I obviate this objection by providing a separate guide for each
wire, any one or more of which guides can be removed and replaced independently
of the others without interrupting the tinning process with respect to the other wires.
In place of employing chucks as hitherto for smoothing the wire as it passes to
the drums and through which chucks the wires have to be threaded provide a

page_text: number of screw presses each constructed with a recess in which the wiping material
is placed, the said recesses being open to allow of the wire being placed therein. In
some of these presses the required pressure is given by means of an arrangement
of worm and worm wheel in combination with a quick acting screw.
By this means the compresser is approximately adjusted and withdrawn in a rapid
manner and greater pressure can be applied to the wire than heretofore.
In order to enable my invention to be fully understood I will describe how it can
be carried into practice by reference to the accompanying drawing, in which
Figure 1 is a longitudinal section partly in elevation of an apparatus for use in the
manufacture of tinned wire, constructed according to my invention the drums which
receive the finished wire being omitted as they are of ordinary construction.
Figure 2 is a plan of half of the said apparatus only one of the improved reels or
swifts being shown.
Figure 3 is a front elevation of figure 1.
Figure 4 is a detached front elevation of one of the scrow presses for smoothing
the wires as they come from the tinning bath.
Figure 5 is a similar view showing one of the removeable guides which I provide in
the tinning bath.
Similar letters in all the figures indicate similar parts.
a is the furnace which I construct entirely of metal as shown in the drawing, the
sides being provided with a narrow lining of brickwork.
b is the tank or bath of ordinary construction placed in the top of the furnace so
as to be heated thereby.
•
cc are the air passages or jackets with which I provide the sides of the furnace for
preventing the heat from causing inconvenience to the workman the said air passages
being formed by fixing a metal plate d on each side of the furnace with distance
pieces e, e placed between.
fis the recess at the lower part of the furnace to allow room for the workınan's feet
for the purpose already explained.
g is one of my adjustable swifts which I construct of a number of bent rods h, h
the inwardly extending portions i, i of which are arranged so that they can be slid in
and out of sockets i, j, cast on bosses k, k on plates 1, 1 forming the top and bottom
of the swift. In this manner the cage formed by the rods h, h can be expanded or
contracted to suit the different sizes of coils of wire to be treated; m, m are pressure
screws for securing the rods h, h in the position to which they have been adjusted.
The swift rotates on a spindle n in a vessel o containing a suitable cleansing solution in
the usual way. p is the coil of wire to be treated.
q, q are the flanged guiding rollers which I employ instead of the guiding pegs
hitherto in use one of such rollers being provided for each wire p for assisting the
passage of the wire and preventing it from stiffening. The rollers q, q are mounted
on a spindler fitted in a bracket s fixed to each side of the usual vessel t containing
the solution for preliminarily treating the wires; u, u are guiding rollers in the
vessel t for conducting the wires into the bath of solution.
vis the flange which I provide on the mop container w and in which I form slots x, x
for the passage of the wires as they leave the bath of solution. By this means I
obviate the risk of the material forming the mop or wiper y being drawn along by the
wires into the tinning bath 6 and thereby causing accidents.
2,2 are my removeable guides constructed and arranged so as to admit of any one
of them being removed and replaced independently of the others. For this purpose
I form the guides separately and provide each of them with a shoulder a¹ and a screw-
threaded neck b', so that the guides can be placed in slots c¹ formed in a bar d
extending across and fixed to the top of the bath b the guides being then secured by
means of nuts e¹ screwed over the necks b'.
ff and g¹, g' are my screw presses which I employ instead of chucks for
smoothing the wires as they pass from the tinning bath b to the drums.
h¹, ¹ are the recesses which I form in the said presses for receiving the wipers i¹
and the said recesses being open at the top as clearly seen in figures 3 and 4 to allow
,

page_text: the wires to be placed therein instead of having to thread them as was the case with
the said chucks.
The presses f, f' are simply formed with a screw-threaded spindle k¹ working in
a bracket on the press and provided with a fixed head m¹ and a hand-wheel n¹ by
operating which, when the wiper and wire have been placed in the recess, any required
degree of pressure can be applied to the said wire.
The press g has a spindle ¹ which is formed with a quick acting screw and
revolves loose in the head m¹. The spindle ¹ does not work in a female thread in the
bracket as is the case with the press f¹ but passes loosely through the bracket
and works in an internally screw-threaded worm wheel o¹ placed in a recess in the
bracket and engaging with a worm p' operated by a handle q'. The spindle ¹ can
be operated by a similar handle r.
is a spring catch working through the head m¹ and entering recesses in the
spindle for the purpose of preventing the spindle k¹ from revolving while the
worm is acting upon it.
The wiper can advantageously consist of two superposed pieces of rubber between
which the wire is placed as shown. When the wiper and wire have been placed in
the recess ', the spring catch s¹ is drawn outwards and the spindle k' is rapidly
rotated by means of the handle until the head m¹ is in contact with the wiper
the spring catch is then released when it will engage in its recess in the the spindle k¹
and hold it while the worm and worm wheel are rotated by means of the handle q',
and by this means very great pressure can be placed upon the wiper.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. Constructing furnaces of apparatus for use in the manufacture of tinned wire of
metal with air passages or jackets or a coating of non-conducting composition at each
side and a recess at the lower part substantially as and for the purposes set forth.
2. Constructing swifts or reels of apparatus for use in the manufacture of tinned
wire in such a manner that they can be reduced or enlarged in diameter to adapt them
to receive wire coils of various diameters substantially as set forth.
3. In apparatus for use in the manufacture of tinned wire, the employment of
independent flanged rollers, such as q and u, for guiding the wires to the vessel
containing the solution for preliminarily treating the wire substantially as set forth.
4. In apparatus for use in the manufacture of tinned wire, forming the mop
container of the solution bath with a slotted flange substantially as and for the purpose
set forth.
5. The employment in apparatus for use in the manufacture of tinned wire, of
independent guides for conducting the wires into the tinning tank or bath substantially
as set forth.
6. The construction and use of the presses for smoothing the wires on their
passage from the tinning tank or bath to the drums substantially as hereinbefore
described and illustrated in the accompanying drawing.
7. The improved apparatus for use in the manufacture of tinned wire substantially
as hereinbefore described and illustrated in the accompanying drawing.
