AN IMPROVED INSTRUMENT OR APPARATUS FOR BEATING OR TRITURATING VISCOUS OR GELATINOUS SUBSTANCES
Year: 1849

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSIAH
LORKIN, of Ivy Lane, in the City of London, Merchant, 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
September, One thousand eight hundred and forty-nine, in the thirteenth year
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Josiah Lorkin, my exors, admors, and assigns, Her especial
licence, full power, sole privilege and authority, that I, the said Josiah
Lorkin, my exors, admors, and assigns, and such others as I, the said Josiah
Lorkin, my exors, admors, 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
"AN IMPROVED INSTRUMENT OR APPARATUS FOR BEATING OR TRITURATING VISCOUS
OR GELATINOUS SUBSTANCES;" in which said Letters Patent is contained a
proviso that I, the said Josiah Lorkin, should cause a particular 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 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.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Josiah Lorkin, hereby declare that the nature of the said Invention, and
in what manner the same is to be performed, are fully described and ascer-
tained in and by the present Specification thereof, reference being had to the
Drawings hereunto annexed, that is to say:-
Figures 1, 2, 3, and 4 of the annexed Drawings are representations of the
said improved instrument or apparatus for beating or triturating viscous or
gelatinous substances, such as eggs, butter, cream, &c., Figure 1 being an
external elevation of the instrument; Figure 2, a sectional elevation of it
with the lid removed; Figure 3, a plan; and Figure 4, a separate plan of
the lid. A, A, is a cylindrical vessel formed of wood, earthenware, metal, or
other suitable material, to the inner surface of which there are affixed three
rows of projecting pins or beaters B, B, B, five in each row, which are so
placed in relation to one another that those of each row come opposite to the
intermediate spaces between the beaters of the opposite row. C is the lid,
which has two projections D, D, which take into a groove E, E, formed in
the lip of the vessel. When the lid is put on, the projections D, D, are
inserted into the openings e, e, through which they gain admission into the
groove E, E, whereupon by turning the lid a little round it becomes securely
and closely fixed in its place. The portions of the eggs or other substance to
be "beat up" being put into the vessel A, A, and the lid put on, as above
described, the vessel is then taken in the hand and shaken to and fro with
such a degree of force as to cause the contents to be driven successively
against the top and bottom and sides of the vessel, during which operation
the beaters B, B, break up and comminute the materials and cause them to
assume the triturated and frothy state desired.
Figure 5 exhibits a modification of the instrument just described. A, A, is
the outer case. B, the lid, to the under side of which there is affixed a stem
or spindle C, to which there are affixed a series of pins or beaters arranged
in the manner shewn in Figure 6, which is a cross section of the spindle
taken on the line a, b. By thus attaching the beaters to a spindle connected
to the lid this advantage is secured, that they can be more readily got at for
the purpose of cleaning.
Figure 7 is a vertical section, and Figure 8 a plan of another modification of
this apparatus. A, A, is the case. B, the lid. C, C, are two projecting rings
or ledges, which are intended to serve the same purpose as the beaters in the
two varieties of the apparatus before described.
Figure 9 is a vertical section, and Figure 10 a plan of another variety of
the instrument. In this case the vessel is fitted inside with two diaphragms of

page_text: wire gauze a, a, the meshes of which are from to of an inch and upwards
in size. The wires produce the same breaking up or triturating action as is
produced by the beaters before described. Or, instead of using wire gauze,
perforated diaphragms of metal or earthenware may be substituted.
Figure 11 is a vertical section, and Figure 12 a cross section of another
modification, in which trituration is effected by rotary action, and which is
specially suited for breaking up large quantities at a time. A, A, is the case.
B, B, a rotary spindle furnished with several rows of pins or beaters C, C.
The spindle has its bearings in the side of the case A. D is a crank handle
by which the spindle and beaters are set in motion. E is the cover. Motion
is given to the crank by hand. In some cases I put a pinion upon the end of
the spindle B, and give motion to it by means of a larger wheel gearing into
it, whereby much greater velocity may be given to the spindle, and the eggs
or other substance may be not only more speedily broken up, but reduced to a
more frothy and triturated state than is otherwise practicable.
Figure 13 is a vertical section, and Figure 14 a plan of an apparatus which
is worked on the whirling principle. A is the case. B, a cover, with a central
boss to receive the spindle of the agitator C, which is furnished with a set of
open fans composed of wire or perforated metal, or of any other suitable
substance with interstices. Rotary or whirling motion is communicated to
the agitator by rolling the upper part of the spindle to and fro between the
hands, or by winding a string round it, the ends of which are pulled alternately
in reverse directions.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I do not restrict myself to
the number, size, position, or order of arrangement of the beaters employed in
the said instrument or apparatus, or to making the same wholly or partially of
any particular material or materials, or to any specific means of giving a
reciprocating, or rotary, or whirling motion to the same; but that what I
claim is, the beating or triturating of viscous or gelatinous substances by
means of an instrument or apparatus consisting of a cylinder (or other suitable
vessel) containing in the inside thereof projecting beaters or intersticial
diaphragms, as before described.
In witness whereof, I, the said Josiah Lorkin, have hereunto set my hand
and seal this Sixteenth day of March One thousand eight hundrad
JOSIAH (L.S.) LORKIN.
