Year: 1857

page_text: LETTERS PATENT to Edward Paige Griffiths, of High Street, Camber-
well, in the County of Surrey, for the Invention of "IMPROVEMENTS IN
APPARATUS FOR BEATING THE WHITES OF EGGS, AND OTHER FLUIDS AND
MATTERS."
Sealed the 17th November 1857, and dated the 27th May 1857.
PROVISIONAL SPECIFICATION left by the said Edward Paige Griffiths
at the Office of the Commissioners of Patents, with his Petition, on
the 27th May 1857.
I, EDWARD PAIGE GRIFFITHS, of High Street, Camberwell, in the, County of
Surrey, do hereby declare the nature of the Invention for "IMPROVEMENTS IN
APPARATUS FOR BEATING THE WHITES OF EGGS, AND OTHER FLUIDS AND MATTERS,"
to be as follows:-
This Invention has for its object improvements in apparatus for beating the
whites of eggs, and other fluids and matters. For these purposes a suitable
frame is constructed to fix on the upper part of a saucepan or other vessel, in
such manner as to be readily removed when the beating of the contents of
the vessel has been accomplished. This frame carries an axis with a crank
handle to enable the user to give a quick rotatory motion to the axis. The
axis gives motion by suitable gearing to two frames, which are caused to
rotate within the vessel in opposite directions, the one frame working within

page_text: the other.
The inner frame has radiating projections made by bending wire,
so that each projection is formed by a wire which proceeds outwards towards
the sides or circumference of the vessel; it is then bent and returns towards
the axis of motion parallel with, but at a distance from the other part of the
bent wire. The outer frame is also formed with projections of a like kind,
but proceeding inwards towards the axis; and the projections of the outer and
inner frames are interspaced, so that in their rotation in opposite directions
the projections of one frame pass between the projections of the other frame.
The forms of the frames and the manner of giving motion thereto may be
varied, so long as they are formed with projections, and the projections of the
different frames are arranged to pass each other.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edward Paige Griffiths in the Great Seal Patent Office on
the 27th November 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
PAIGE GRIFFITHS, of High Street, Camberwell, in the County of Surrey, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-seventh day of May, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twentieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Edward Paige Griffiths, Her special licence, that I, the said Edward Paige
Griffiths, my executors, administrators, and assigns, or such others as I, the
said Edward Paige Griffiths, my executors, administrators, and assigns, should
at any time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for "IM-
PROVEMENTS IN APPARATUS FOR BEATING THE WHITES OF EGGS, AND OTHER FLUIDS
AND MATTERS," upon the condition (amongst others) that I, the said Edward
Paige Griffiths, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what manner
the same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately after.
the date of the said Letters Patent.

page_text: NOW KNOW YE, that I, the said Edward Paige, Griffiths, do hereby
declare the nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say :-
This Invention has for its object improvements in apparatus for beating the
whites of eggs, and other fluids and matters. For these purposes a suitable
frame is constructed to fix on the upper part of a saucepan or other vessel, in
such manner as to be readily removed when the beating of the contents of the
vessel has been accomplished. This frame carries an axis with a crank handle
to enable the user to give a quick rotatory motion to the axis. The axis
gives motion by suitable gearing to two frames, which are caused to rotate
within the vessel in opposite directions; the frames are furnished with projec-
tions which are interspaced, so that in their rotation in opposite directions the
projections of one frame pass between the projections of the other frame.
The forms of the frames and the manner of giving motion thereto may be
varied, so long as they are formed with projections, and the projections of the
different frames are arranged to pass each other.
And in order that my said Invention may be most fully understood and
readily carried into effect I will proceed to describe the Drawings hereunto
Figure 1 is a plan, and Figure 2 is a vertical section, of an apparatus for
beating the whites of eggs, and other fluids and matters, arranged according
to my Invention.
The frame of the apparatus consists of three arms a, a, a, radiating from
a central boss a¹, and of a standard or upright a², rising from one of the
radial arms a. The standard a carries a horizontal axis 6 and a vertical
axis c; the axis 6 carries at one end a bevilled wheel 6', and at the other a
handle 6, by which it can be driven; at the upper end of the vertical axis is
a bevilled pinion c³, arranged to work with the wheel 61; and at the lower end
of the axis c are two arms c², c, each formed of a strip of tin plate bent to a
trough-like form; and to these arms are attached vertical projections c³, c³,
which are also formed of loops of wire soldered at their ends to the arms c².
The bevilled wheel 6¹ also drives a pinion d, fixed on the short tube d", which
at its lower end has fixed to it arms d² similar to the arms c³, from which
descend projections d³ similar to the projections c. The ends of the arms
a, a, are turned down so as to fit over the edge of the saucepan or other
vessel e, in combination with which the apparatus is to be used; and, in order

page_text: that the apparatus may be securely attached to this vessel two pins e¹, e¹, are
fixed to its edge, and projections a³, a³, at the end of two of the arms a, pass
under these pins; at the end of the third arm a, is a set screw a', which enters
a recess e², formed in the edge of the vessel e. In this way the apparatus can
be readily fixed to the vessel e, and when it has been used it can be with equal
facility removed from it. It will be seen that by turning the handle b³, the
arms and d² will be caused to revolve in opposite directions with con-
siderable rapidity, and the projections which these arms carry rapidly and
effectually beat the white of egg, or other fluid or matter, contained in the
vessel e.
Sheet 2 of the Drawings shows au apparatus similar to that already
described, but having the beating projections placed in a horizontal in place
of a vertical position.
In witness whereof, I, the said Edward Paige Griffiths, have hereunto
set my hand and seal, this Twenty-fifth day of November, in the year
of our Lord One thousand eight hundred and fifty-seven.
Witness,
GEO. PITT.
EDWARD PAIGE GRIFFITHS. (L.S.)
