OF ALTERATION.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
GRIFFITHS, of Clifton, Engineer, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by
Her Royal Letters Patent under the Great Seal of the United Kingdom
of Great Britain and Ireland, bearing date at Westminster, the Twentieth
day of October, in the fifteenth year of Her reign, did, for Herself, Her
heirs and successors, give and grant unto me, the said Robert Griffiths, my
exors, admors, and assigns, Her especial licence, full power, sole privilege
and authority, that I, the said Robert Griffiths, my exors, adñiors, and
assigns, or such others as I, the said Robert Griffiths, my exors, adñors,
or assigns, should at any time agree with, and no others, from time to
time and at all times during the term of years therein expressed, should
and lawfully might make, use, exercise, and vend, within England, Wales,
and the Town of Berwick-upon-Tweed, my Invention of "APPARATUS FOR
IMPROVING AND RESTORING HUMAN HAIR;" in which said Letters Patent is
contained a proviso that I, the said Robert Griffiths, shall cause a parti-
cular description of the nature of my said Invention, and in what manner
the same is to be performed, by an instrument in writing under my hand
and seal, to be inrolled in Her said Majesty's High Court of Chancery

page_text: within six calendar months next and immediately after the date of the said
in part recited Letters Patent, as in and by the same, reference being thereunto
had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Robert Griffiths, do hereby declare that the nature of my said Invention,
and the manner in which the same is to be performed, are fully described
and ascertained in and by the following statement thereof, reference being
had to the Drawing hereunto annexed, and to the figures and letters marked
thereon, that is to say :-
My Invention consists of constructing combs, brushes, or such like instru-
ments for combing and brushing the hair, that when in use and passed through
the hair electric currents may be given off, and thereby the skin caused to be
stimulated, and a healthy action produced, which will have the effect of restoring
color to the hair, and generally to improve its appearance. Combs and brushes
may either be made of different metals, so as to become a battery in themselves,
or they may be of metal, or partly of metal, and have batteries connected there-
with when in use, and the arrangement of the parts may be greatly varied;
but the arrangements shewn by the Drawing will, I believe, be found as con-
venient as may be for the purpose. I do not, however, confine myself to the
arrangements shown, so long as combs or brushes, or such like instruments, are
made suitable for carrying out my Invention.
DESCRIPTION OF THE DRAWING.
Figure 1 shows a comb made according to my Invention; Figure 2 is a
longitudinal section thereof, and Figure 3 is a transverse section thereof.
The teeth are alternately of copper and zinc, or other metals suitable for com-
posing a galvanic battery, and they are connected together by being run on a
wire a, there being a metal washer between each neighbouring pair of teeth.
b is a hollow back fixed on the upper parts of the teeth. c is a wire on which
is to be wound worsted or other fibre; and when intended to be used such
wire with its covering is to be dipped into a solution of common salt or very
dilute acid, or other fluid suitable for producing action on the metals. The
wire with its covering is then to be slided into its case, and the effect of this
arrangement will be that when the comb is passed through the hair the
moisture on the skin and in the hair will sufficiently make up a complete
electric circuit to cause currents of electricity to pass through the teeth and
through the fluids in the hair, and thus produce the desired effect; or in place
of making the comb so as to contain or be its own battery, it may simply

page_text: consist of a series of metallic points in connection with a separate battery, but
I prefer the arrangement above given, but do not confine myself to the form of
the parts.
Figure 4 shows an edge view, and Figure 5 a transverse section of a
brush made according to my Invention, the points being made of very fine
metal wire set in india rubber or other elastic substance, which may also have
a hollow back for air, and the upper part of the back is also made hollow
to contain a battery, which I prefer to construct as follows:-d, d, are two
plates of zinc, having between them two surfaces of woollen cloth saturated
when in use with a solution of common salt, or other suitable fluid. e, e, are
two plates of copper, also having surfaces of saturated cloth between them.
These two pairs of plates are put in metallic connection with the teeth by
means of two plates f, g, by which arrangement, when the brush is passing
through the hair, the fluids on the skin and in the hair will sufficiently close
the circuit, and currents of electricity will pass through the fluids and the
teeth of the brush so as to produce the desired result.
Figures 6 and 7 show a side view and section of another arrangement of
brush, in which case a similar battery is applied in the back, as shown, and
each of the two pairs of plates is to be in suitable metallic connection with two
or more rows of wires h, i, so that when in use circuits will be closed or made
complete by the fluids on the skin and in the hair, so that electric currents
will pass between the points h and i. The other parts of the brush in this case
are intended to be of bristles, and wires h, i, are intended to be very fine,
though shewn coarse in the Drawing. I would hero state that here, as in the
case of the combs, that the instrument itself may be separate from the battery,
but I prefer that the whole should be combined into one instrument, as shewn,
though the arrangement and form of the parts may be varied, and other metals
be used in making the batteries.
may
Having thus described the nature of my Invention, and the manner of per-
forming the same, I would have it understood that what I claim is the
arranging or combining parts into combs, brushes, or such like instruments
suitable for passing through the hair or against the skin, and so that electric
currents may be obtained when in use, as herein explained.
In witness whereof, I, the said Robert Griffiths, have hereunto set my
hand and seal, this Twentieth day of October, in the year of our Lord
One thousand eight hundred and fifty-two.
ROBERT (L.S.) GRIFFITHS.

page_text: AND BE IT REMEMBERED, that on the Twentieth day of October,
in the year of our Lord 1852, the aforesaid Robert Griffiths came before our
said Lady the Queen in Her Chancery, and acknowledged the Specification
aforesaid, and all and every thing therein contained and specified, in form above
written. And also the Specification aforesaid was stamped according to the
tenor of the Statute made for that purpose.
Enrolled the Twentieth day of October, in the year of our Lord One
thousand eight hundred and fifty-two.

page_text: MEMORANDUM OF ALTERATION proposed to be entered by the
above-named Patentee with the Clerk of the Patents of England,
according to the Statute in that case made and provided.
Whereas I, the said Robert Griffiths, have discovered that my said Specifi-
cation, in reciting the date of the said Letters Patent, stated it to be of the
Twentieth day of October in error for the Twentieth day of April; I therefore
strike out the word October and insert the word April. And I have been
advised that the first paragraph of the description of the parts shown by the
Drawing may be rendered more full and clear, and thus enable a less skilled
workman to carry out my Invention, if additional information be given.
I do therefore alter the said Specification by introducing the words "coated
with insulating material" after the letter a, and also again after the word
washer. And I also introduce the words "the teeth being separated by a
washer of felt" after the word "teeth." By which such paragraph will, when
altered, be as follows: "The teeth are alternately of copper and zinc, or other
metals suitable for composing a galvanic battery, and they are connected
together by being run on a wire a, coated with insulating material,"
there being a metal washer coated with insulating material between each
neighbouring pair of teeth, the teeth being separated by a washer of
felt."
In witness whereof, I, the said Robert Griffiths, have hereunto set my
hand and seal, this Fifteenth day of February, in the year of our Lord
One thousand eight hundred and fifty-five
