Sealed the 3rd September 1867, and dated the 7th March 1867.
PROVISIONAL SPECIFICATION left by the said Alfred Giles at the
İ,
Office of the Commissioners of Patents, with his Petition, on the
7th March 1867:
I, ALFRED GILES, of Manchester, in the County of Lancaster, Engineer,
do hereby declare the nature of the said Invention for "AN IMPROVED MIXING
APPARATUB, ALBO APPLICABLE TO BEATING EGGS, AND TO OTHER SIMILAR PURPOSES,"
to be as follows:-
My Invention consists in using a vessel which may be made of glass or
other suitable material, and of a cylindrical or other convenient form; into
which the materials to be mixed or beátéń up are placed; into the interior of

page_text: this vessel a rod projects having one or more diaphragms, which may be
perforated plates or open wirework, and of such a size as almost to fill
up the whole area of the vessel. This rod, and the diaphragm or diaphragms,
can be made entirely of glass or any other suitable material, and it may be
attached to the inside of the cylinder, or made separate or attached to a
removeable cover, which latter plan I prefer to adopt; the diaphragms
may also be attached to the vessel, which may be made of such a form that
the area of the interior is varied, being larger or smaller at different points in
its length.
The action of the apparatus is as follows:-The materials to be mixed are
placed in the vessel; the rod with the diaphragms upon it is then placed in
its position, and the cover, which is made to fit water-tight, is put on and held
firmly in its place while the vessel is vigorously shaken, so that the contents
are caused to pass to and fro through the meshes or openings left in the
diaphragm, thus causing the materials to be well beaten up and broken or
mixed. When this is required to be done on too large a scale to be performed
by hand, machinery may be applied to give the necessary agitation to the
vessel.
The apparatus is applicable to mixing, beating eggs, and similar purposes,
such as churning
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Alfred Giles in the Great Seal Patent Office on the
4th September 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALFRED
GILES, of Manchester, in the County of Lancaster, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventh day of March, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Alfred Giles, Her special licence that I, the said Alfred Giles, my
executors, administrators, and assigns, or such others as I, the said Alfred
Giles, 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
.

page_text: Channel Islands, and Isle of Man, an Invention for "AN IMPROVED MIXING
APPARATUS, ALSO APPLICABLE TO BEATING EGGS, AND TO OTHER SIMILAR PURPOSES,"
upon the condition (amongst others) that I, the said Alfred Giles, 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.
NOW KNOW YE, that I, the said Alfred Giles, do hereby declare the nature
of my said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following state-
ment:-
My Invention consists in using a vessel which may be made of glass or
other suitable material and of a cylindrical or other suitable form into which
the materials to be mixed or beaten up are placed; into the interior of this
vessel a rod projects having one or more diaphragms, which may be perforated
plates. or open wirework, and of such a size as almost to fill up the whole area
of the vessel. This rod, and the diaphragm or diaphragms, can be made
entirely of glass or any other suitable material, and it may be attached to the
inside of the cylinder, or made separate or attached to a removeable cover,
which latter plan I prefer to adopt; the diaphragms may also be attached to
the vessel, which may be made of such a form that the area of the interior
is varied, being larger or smaller at different points in its length.
The action of the apparatus is as follows:-The materials to be mixed are
placed in the vessel; the rod with the diaphragms on it is then placed in its
position, and the cover, which is made to fit water-tight, is put on and held
firmly in its place while the vessel is vigorously shaken, so that the contents
are caused to pass to and fro through the meshes or openings left in the
diaphragm, thus causing the materials to be well beaten up, and broken or
mixed. When this is required to be done on too large a scale to be performed
by hand machinery may be applied to give the necessary agitation to the
vessel.
The apparatus is applicable to mixing, beating eggs, and similar purposes,.
such as churning.
In order that my Invention may be more clearly understood I now proceed
to describe the annexed Drawing, which shows the best modes that I am. at
present acquainted with for putting my Invention into practice..

page_text: DESCRIPTION OF THE DRAWING.
In Fig. 1, A is the cylindrical. vessel, in, this case the diaphragm B is
attached to the rod C, which is fixed to the bottom of vessel.A.
In Fig. 2, A is the vessel, and B the diaphragm which is attached, at once.
to the vessel A; a convenient mode of doing this is to pierce small holes in, 5
the side of the vessel and run straight wires through from side to side. The
vessel may also be made of the form shown in Fig. 3, which will, be found,
more convenient for holding in the hand.
Figs. 3 and 4 show an apparatus in which the vessel and diaphragm are
separate. A is the vessel; the diaphragm. B is attached to the rod C, which, 1
is fixed to the cover D. Fig. 5 shows the same apparatus with the diaphragm,
in its place. Figs. 6, 7, and 8 show different forms of diaphragms.
Other forms of vessels and diaphragms may also be used without departing
from the principle of the Invention, which consists in the, use, of a vessel,
having open wirework or other suitable material inside so as to form meshes, 1
through which the materials pass to and fro when the vessel is agitated: A.
small air hole should be made in the cover, and it might be closed. by, the
finger, or by a valve pressed by the finger..
Fig. 9 shows another form which I propose to adopt when making the
vessels of tin. The diaphragm and rod, are shown in dotted lines, and the 2
apparatus is furnished with a handle A.
Fig. 10 shows an apparatus for beating eggs or mixing on a larger scale
than those above described. A is the mixing vessel which works, on, a.,
fulcrum B, a swinging motion being imparted to it by means of the handle, C
and lever D; E, E, are the diaphragms, and F, F, are doors or lids, by means
of which the materials are put into or taken from the vessel.
Fig. 11 is another form of apparatus applicable to beating eggs, and mixing.
on a large scale. A is the vessel which is connected to the links B, B¹; a
backward and forward motion is imparted to the vessel by means of a crank C
connected by the rod D to the link, B; the crank C is, on a shaft E which 3
may be driven by means of a hand wheel F, or by means of a belt passing.
round a pulley; G, G, are the diaphragms.
Any convenient number of diaphragms may be employed in one apparatus,
but when more than one is used they should not be arranged so that the open..
spaces in one diaphragm will come exactly opposite, those in the next, but so 3
that they may break joint with one a
one another.
It is often desirable that the materials should be fed into and discharged.
I

page_text: from the mixing vessel continuously; this I accomplish by first putting the
materials into the vessel H, which communicates with the mixing vessel A by
means of a flexible pipe I, the materials being discharged through another
flexible pipe K into the vessel L, the flexibility in the pipes I and K allowing
for the motion of the vessel A.
In witness whereof, I, the said Alfred Giles, have hereunto set my hand
and seal, this Second day of September, in the year of our Lord One
thousand eight hundred and sixty-seven.
ALFRED GILES. (L.S.)
