I GEORGE FREDERICK REDFERN, of the General Patent Office, No. 4 South Street,
Finsbury, in the county of Middlesex, Patent Agent, do hereby declare the nature
of this invention to be as follows:-
This invention relates to improvements in the manufacture of metal combs for the
hair, the teeth of which combs according to this invention are made of a similar
shape to that of the teeth of ordinary horn combs, that is to say either an elliptical
or a flat shape in cross section whereby these teeth can be arranged in as close
proximity to one another as those of ordinary horn combs so that combs manufactured
according to this invention are apart from their mode of construction similar to
ordinary combs with this exception that they possess a much greater strength than
the former.
The combs constructed according to this invention consist of teeth flat or elliptical
in cross section, such teeth being inserted in a back or frame formed of a bent steel
plate to which the said teeth are soldered. This back or frame is curved so as to
assume the shape of the letter U and its shank or lower extremity is suitably slotted
according to the distance between each two adjacent teeth. The slotted shank is
then bent over inwardly and the teeth are inserted into their respective slots. The
upper extremities of the teeth which are of steel thus completely fill up the slots of
the said back or frame and are fixed therein by means of solder. As further means
for consolidating and strengthening the comb, the portion of the upper extremity of
the teeth which enters the back or frame may be provided upon one of its flat sides
with projecting ribs or protuberances.

page_text: The backs or frames of one half of such combs may also consist of steel while the
other half may be composed of any other suitable metal or alloy.
.I sometimes attach the teeth in the back or frame of the comb by bending a piece
of steel and providing the lower part thereof with perforations or slots through
which the teeth are passed the upper part of the said back or frame being afterwards
closed by means of solder.
The back or frame may also be formed of two separate parts, the lower part being
also provided with holes or slots through which the teeth are inserted. The whole is
afterwards soldered together.
Combs of all description and even the finest dandruff or scurf combs may be
manufactured in the above described manner.

I, GEORGE FREDERICK REDFERN, of the General Patent Office, No. 4, South Street,
Finsbury, in the county of Middlesex, Patent Agent, do hereby declare the nature
of this invention (a communication from abroad by Auguste Knippenberg, of
Ichtershausen, in the empire of Germany, Manufacturer) 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 improvements in the manufacture of metal combs for the
hair, the teeth of which combs according to this invention are made of a similar
shape to that of the teeth of ordinary horn combs, that is to say, either an elliptical
or a flat shape in cross section whereby these teeth can be arranged in as close
proximity to one another as those of ordinary horn combs so that combs manufactured
according to this invention are apart from their mode of construction similar to
ordinary combs with this exception that they possess a much greater strength than
the former.
In order to enable the invention to be fully understood I will describe how it can
be carried into practical effect by reference to the accompanying drawing the several
figures of which represent views of combs manufactured according to these
improvements.
As shewn in the cross section and part side elevation at figures 1 and 3 respectively,
the combs constructed according to this invention consist of teeth a, flat or elliptical
in cross section, as shewn in figure 5, such teeth being inserted in a back or frame
formed of a bent steel plate to which the said teeth are soldered. This back or
frame b, (as shewn in figures 1 and 3 and also in figure 2 which is a side elevation
of part of the said back or frame) is curved so as to assume the shape of the letter U
and its shank or lower extremity is suitably slotted according to the distance
between each two adjacent teeth as clearly shown in figure 2. The slotted shank b¹,
is then bent over inwardly as shewn in figure 1 and the teeth a, are inserted into
their respective slots. The upper extremities of the teeth a, which are of steel thus
completely fill up the slots of the said back or frame b, and are fixed therein by
means of solder. As further means for consolidating and strengthening the comb,
the portion of the upper extremity of the teeth which enters the back or frame may
be provided upon one of its flat sides with projecting ribs or protuberances as clearly
shewn in figure 9 which represents in elevation and edge view one of the teeth so
formed.
The backs or frames of one half of such combs may also consist of steel while the
other half may be composed of any other suitable metal or alloy.
Figure 4 represents in cross section and part side elevation a comb having a back
or frame arranged in this manner; d, is the slotted part which is made of a metallic
alloy and
in the sectional view is the part formed of steel; (in the side elevation this
e,

page_text: plate of steel e, is not shown). In this case also the teeth a, are soldered to the back
or frame.
I sometimes attach the teeth in the back or frame of the comb by bending a piece
of steel and providing the lower part thereof with perforations or slots through which
the teeth are passed the upper part of the said back or frame being afterwards closed
by means of solder as illustrated by the cross section figure 7.
The back or frame may also be formed of two separate parts 63, and 63, as shewn in
cross section at figure 8, the lower part 63, being also provided with holes or slots
through which the teeth are inserted. The whole is afterwards soldered together.
Combs of all descriptions such for example as those represented in side elevation and
end view at figure 6, and in side elevation at figures 10 and 11, and even the finest
dandriff or scurf combs may be manufactured in the above described manner.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed I declare that what I claim is :-
A metallic comb for the hair consisting of flat or oval teeth inserted and soldered
within a metal frame or back either entirely composed of steel or other suitable metal
or formed of two parts one part being made of steel and the other part of a suitable
metallic alloy.
