PROVISIONAL SPECIFICATION.
New or Improved Appliances or Apparatus for use in Galvanizing
Tubes, Rods, and Bars of Iron and Steel.
We HENRY HUNT BRAND, and CHARLES SKINNER BRAND, trading as
Brand Brothers of Rough Hills Galvanizing Works Wolverhampton and King's
Hill Galvanizing Works Wednesbury both in the County of Stafford Galvanizers
do hereby declare the nature of this invention to be as follows
Our invention has for its object to remove the superfluous zinc which attaches
itself to tubes, rods and bars of iron and steel as they are drawn from the bath of
melted zinc in which they have been galvanized; and consists of the appliances or
apparatus hereinafter described for wiping the said tubes, rods and bars on their
emergence from the bath and thereby removing the superfluous zinc therefrom.
The said wiping also produces a smooth surface on the tubes, rods and bars of iron
or steel.
The appliances or apparatus constituting our invention consist of a wiper the
acting part of which is made of compressed cotton or vegetable fibre rendered
incombustible by having been soaked in a solution of boracic acid, tungstate of
soda or other solution which will render it incombustible. The said incombustible
cotton may either be used in an unwoven state or woven in the form of belting.
The said cotton is placed in and supported by a holder fixed near the part of
the bath from which the tube rod of bar emerges. The said holder has openings
at front and back of approximately the size and shape of the cross section of the
tube or article being galvanized. The said holder is preferably made in two or
more parts capable of separating and closing pressed together by a weight or spring.
The compressed cotton or vegetable fibre is thereby pressed upon the tube, rod or
bar being drawn through the holder and the superfluous melted ziuc removed
therefrom.
Where the tube, rod or bar is cylindrical the holder may be made of a coil of
flat steel which by its elasticity tends to close upon and press the cotton fibre
contained in it with the required pressure on the tube or article.

Tubes, Rods, and Bars of Iron and Steel.
We HENRY HUNT BRAND and CHARLES SKINNER BRAND, trading as
Brand Brothers, of Rough Hills Galvanizing Works, Wolverhampton, and King's
Hill Galvanizing Works, Wednesbury, both in the County of Stafford Galvanizers,
do hereby declare the nature of our invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement :-
Our invention has for its object to remove the superfluous zinc which attaches
itself to tubes, rods and bars of iron and steel as they are drawn from the bath of
melted zinc in which they have been galvanized; and consists of the appliances or
apparatus hereinafter described for wiping the said tubes, rods and bars on their
emergence from the bath and thereby removing the superfluous zinc therefrom.
The said wiping also produces a smooth surface on the tubes, rods and bars of iron
or steel.
The appliances or apparatus constituting our invention consist of a wiper the
acting part of which is made of compressed cotton or other vegetable or animal
fibre rendered incombustible by having been soaked in a solution of alum or boracic
acid or tungstate of soda or other solution which will render it incombustible. We
prefer to use saturated or nearly saturated solutions of alum or boracic acid or
tungstate of soda or other like solution and to soak the compressed cotton or other
compressed fibre therein until the solution has thoroughly permeated the said
compressed cotton or fibre. The said incombustible cotton may either be used in
an unwoven state or woven in the form of belting such as the cotton belting of
commerce. The said cotton is placed in and supported by a holder fixed near the
part of the bath from which the tube rod or bar emerges. The said holder has
openings at front and back of approximately the size and shape of the cross section
of the tube or article being galvanized. The said holder is preferably made in
two or more parts capable of separating and closing, pressed together by a weight
or spring. The compressed cotton or vegetable fibre is thereby pressed upon the
tube, rod or bar being drawn through the holder and the superfluous melted zinc
removed therefrom.
Figure 1 of the accompanying drawing represents in front elevation our new or
improved appliances or apparatus applied to the emerging end of a galvanizing
bath for wiping and thereby removing the superfluous zinc from the galvanized
iron or steel tubes, rods or bars as they emerge from the said bath. The acting
parts of the wiper in the said Figure 1 are represented separated; Figure 2
represents in back elevation and side elevation (partly in cross section) the wiper
and its holders drawn to a larger scale than Figure 1, the moveable part of the
wiper being represented in its depressed and acting position; and Figure 3
represents the appliances shown in Figure 2 with the movable part of the wiper
and its holder in their raised positions as represented in Figure 1.
The same letters of reference indicate the same parts in the several figures of
the drawing.
.
a is the front or emerging end of the bath containing the melted zinc with which
the tubes, rods or bars are to be coated or galvanized; b, c are the halves or acting
parts of the wiper made preferably of pieces of cotton belting rendered incom-
bustible by being treated in the manner hereinbefore described, but the said acting
parts of the wiper may be made of compressed cotton in other forms or of other
vegetable or animal fibre treated as described. Each of the opposed edges of the
acting parts b, c of the wiper has in its middle a nearly semi-circular opening

page_text: marked respectively and c², the said openings when brought together having
approximately the size and shape of the cross section of the tube (or article)
being galvanized. The lower fixed acting part 6 of the wiper is secured to a
holder consisting of the two plates d and e, and the said holder is fixed to the angle
bar at the front or emerging end of the bath. By means of the screw bolts and
nuts at g the incombustible cotton belting b is gripped between the two plates de
of the holder and the said holder and cotton belting fixed to the angle bar f.
The top of the plate d of the holder has a semi-circular opening in it of larger size
than that in the cotton belting or half wiper b. The upper movable acting half c
of the wiper is similarly bolted at h to the slide i working in dovetails k, k carried
by the fixed cross plate bolted to the vertical bars or uprights at the front of the
bath. The slide carrying the upper acting half of the wiper is lifted into its
raised or non-acting position Figures 1 and 3, and indicated in dotted lines in
Figure 2, by the coiled springs m, m m (see Figure 1) acting upon the plate n, the
latter being connected to the slide i by the rod p. The slide i is depressed and
with it the acting half c of the wiper by the hand lever q pivoted at 93 to one of
the side supports at the end of the bath, and connected to the slide i by the link
pivoted thereto at 72. On depressing the hand lever q, the slide takes the
position represented in Figure 2 and the lower portion of the acting half c of the
wiper is brought near to the upper edge of the fixed bottom half of the wiper
the semi-circular openings in the two halves of the wiper being situated one in
advance of the other so as to form between them a circular opening for the passage
through it of the tube rod or bar being galvanized (see Figure 2). On the
depression of the half c of the wiper, its outer inclined edges pass between the
springs s, s at the back of the holder plate d (see Figure 2) and the opening in
the said half of the wiper is thereby made to press upon the tube as it is drawn
from the bath.
In using the apparatus the lever q is depressed thereby compressing the coiled
springs m, m, m, and the two acting parts b, c of the wiper are brought together,.
the workman by pressure on the lever holding down the upper half of the wiper in
its acting position. As the galvanized tubes, bars or rods emerge from the bath
they are drawn obliquely through the circular opening formed by the opposed
edges of the halves of the wipers b, c; the superfluous melted zinc is thereby wiped
or removed from the tubes, rods or bars and a smooth surface at the same time
produced. A pipe t connected with the water tank u may be conducted to the
front of the acting parts of the wiper. By means of the said pipe, a small jet of
water may be allowed to fall upon the tube, rod or bar immediately it has passed
through the acting parts of the wiper. A bright and silvery appearance is thereby
given to the surface of the tube rod or bar.
On loosing the lever g the upper half c of the wiper is lifted into its raised or
out of action position by the elongation of the coiled springs m, m, m connected
with the slide i.
Where the tube, rod or bar is cylindrical the holder may be made of a coil of flat
steel which by its elasticity tends to close upon and press the cotton or other fibre
contained in it with the required pressure on the tube or article.
Having now particularly described and ascertained the nature of our inven-
tion and the manner in which the same is to be performed we declare that we
are aware of the Specification of Thomas and Hillman's Patent No. 8,572 of 1890,
and we make no claim to anything described and claimed therein but we claim as
our invention of "New or improved appliances or apparatus for use in galvanizing
tubes, rods and bars of iron and steel
Removing the superfluous melted zinc from and at the same time giving a smooth
surface to the tubes rods or bars as they emerge from the galvanizing bath, by the
use of a wiper made and arranged as hereinbefore described and illustrated in the
accompanying drawing; that is to say, a wiper the acting parts of which are made
of pieces of compressed cotton, such as the cotton belting of commerce, or of other

page_text: compressed vegetable or animal fibre, the said compressed cotton or fibre being
rendered incombustible by treating it in the manner hereinbefore described, the
two acting parts of the wiper being so secured in holders, one fixed and the other
movable, that the moveable acting part can be separated from or brought to the
fixed acting part for the purpose and substantially as described and illustrated.
