Year: 1860

page_text: LETTERS PATENT to James Lamb Hancock, of Pentonville Road, in the
County of Middlesex, Manufacturer, for the Invention of "AN IMPROVED
APPARATUS FOR WORKING AND SHAPING BUTTER, AND FOR SEPARATING IT
FROM THE BUTTERMILK."
Sealed the 27th September 1860, and dated the 28th March 1860.
PROVISIONAL SPECIFICATION left by the said James Lamb Hancock
at the Office of the Commissioners of Patents, with his Petition, on the
28th March 1860.
I, JAMES LAMB HANCOCK, of Pentonville Road, in the County of Middlesex,
Manufacturer, do hereby declare the nature of the said Invention for "AN
IMPROVED APPARATUS FOR WORKING AND SHAPING BUTTER, AND FOR SEPARATING
IT FROM THE BUTTERMILK," to be as follows: _
My apparatus consists of a jar or vessel open at top and perforated at
bottom with circular or other shaped apertures, and with the rim formed with
a flange or recess on the inside with portions of the rim removed. Butter is
placed in the vessel and a piston is inserted on the top thereof, a nut is intro-
duced in the flanged rim, the portions removed admitting of its introduction; a
screw is then inserted and turned down through the nut, whereupon the butter
is expressed in a divided state through the apertures in the bottom of the
vessel. Instead of the nut for the screw being placed inside the flanged rim,
it may be fitted on the outside of the vessel; movable perforated plates may
be used for the bottom of the vessel.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
LAMB HANCOCK, of Pentonville Road, in the County of Middlesex, Manufuc-
turer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of March, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-third year of IIer reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
James Lamb Hancock, Her special licence that I, the said James Lamb
Hancock, my executors, administrators, and assigns, or such others as I, the
said James Lamb Hancock, 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 "An
IMPROVED APPARATUS FOR WORKING AND SHAPING BUTTER, AND FOR SEPARATING
IT FROM THE BUTTERMILK," upon the condition (amongst others) that I, the
said James Lamb Hancock, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, should par-
ticularly 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 James Lamb Hancock, 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 statement thereof, reference being had to the Drawings hereunto
annexed, that is to say :-
My apparatus consists of a jar or vessel open at top, and perforated at
bottom with circular or other shaped apertures, and with the rin formed with
a flange or recess on the inside, with portions of the rim removed. Butter is
placed in the vessel and a piston is inserted on the top thereof; a nut is intro-
duced in the flanged rim, the portions removed admitting of its introduction;
a screw is then inserted and turned down through the nut, whereupon the
butter is expressed in a divided state through the apertures in the bottom of

page_text: the vessel. Instead of the nut for the screw being placed inside the flanged
rim, it may be fitted on the outside of the vessel; movable perforated plates.
may be used for the bottom of the vessel.
Figure 1 of the accompanying Drawings is a plan of an apparatus for.
working and shaping butter, and for separating it from the buttermilk, con-
structed according to my Invention, fitted in a frame; Figure 2 is a longitu-
dinal section through the line x, y, of Figure 1. a is a jar or vessel open at top,
the upper part or rim of which is formed with a flange; b, c, is a piston of or
about the circumference of the interior of the jar; a, d, is a screw-threaded
rod connected to the piston, and carrying on its upper end a handle e; this
rod works through a nut f; g, is a perforated metal plate, placed in the
bottom of the jar or vessel a, or the bottom itself may be perforated or pierced.
To use the apparatus for the sake of convenience, I place it in a frame h pro-
vided with handles i, i, i, i, the flange 6 rests on a metal plate k, supporting a
flanged rim l. The frame h with the jar is then placed on an ordinary tub, as
for example, one similar to that shewn at m, Figure 2. The butter to be
operated on is put in the vessel a, and the piston inserted upon it; the handle
e is then turned, which drives the piston down and forces the butter out in
thin flakes or filaments through the perforated plate or bottom of the vessel a,
into cold water in the tub m, where it becomes chilled and freed from all
traces of milk and whey. The nut is turned so as to bring the ends free from
the flange when it and the piston and screw are removed from the jar. In
some cases I perforate the sides of the jar or vessel near the bottom, as shown
in Figure 2; Figure 3 is a side elevation of a frame or "saddle," shewing the
jar or vessel a, supported in it at a slight angle from the horizontal line. After
the butter has been washed, as just described, the jar or vessel is removed
from the frame, before mentioned, and placed in the "saddle," the washed
butter is inserted in it and is formed into any desired shapes by being driven
by the piston through plates having the necessary perforations or apertures
made in them; the butter which is forced through the apertures may be
received on a slab o, there to be cut into any required lengths.
Butter can be formed into a variety of shapes for the table and garnishing
purposes, by altering the form of the holes in the plates at the bottom of the
jar; for example, a plate, similar to that represented at Figure 4, would pro-
duce butter in lengths like maccaroni through the holes marked p, and in
long corrugated flat lengths through that marked r; Figure 5 is à view of a
plate for producing the butter in long thin flakes or filaments either flat or
corrugated.

page_text: And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim the construction
and employment of an apparatus for working and shaping butter, and for
separating it from the buttermilk, substantially in the manner herein-before
described and illustrated in the accompanying Drawings.
In witness whereof, I, the said James Lamb Hancock, have hereunto
set my hand and seal, this Twenty-eighth day of September, One
thousand eight hundred and sixty.
JAMES LAMB HANCOCK. (L.S.)
