Year: 1857

page_text: LETTERS PATENT to Thomas Brower, of Neithrop, Banbury, in the
County of Oxford, Whitesmith, for the Invention of "IMPROVEMENTS IN
MACHINES FOR CUTTING AND REDUCING TURNIPS OR OTHER VEGETABLE
SUBSTANCE3."
Sealed the 1st December 1857, and dated the 1st July 1857.
PROVISIONAL SPECIFICATION left by the said Thomas Brewer at the
Office of the Commissioners of Patents, with his Petition, on the
1st July 1857.
I, THOMAS BREWEB, of Neithrop, Banbury, in the County of Oxford,
Whitesmith, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN MACHINES FOR CUTTING AND REDUCING TURNIPS OR OTHER VEGETABLE
SUBSTANCES," to be as follows:-
My improvements have referenco to the well-known disc turnip cutter, and
consist in so constructing the disc that it will first slice the root, and then by
means of stucks, or other projections, carry the pieces of sliced root through a
series of teeth, knives, or projections arranged in one or more fixed shields or
guards, which are so placed with respect to the revolving disc as to act as a
receptacle for and to retain the cut slices until the projections in the revolving
disc come round, and carry the slices through the teeth or projections in the
shields or guard, causing the root to be completely minced.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Brewer in the Great Seal Patent Office on the
29th December 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
BREWER, of Nethrop, Banbury, in the County of Oxford, Whitesmith, send
greeting.
WHEREAS er most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the First day of July, in the year of our Lord One
thousand eight hundred and fifty-seven, in the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Thomas Brewer, Her special licence that I, the said Thomas Brewer,
my executors, administrators, and assigns, or such others as I, the said
Thomas Brewer, 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 "IMPROVEMENTS IN
MACHINES FOR CUTTING AND REDUCING TURNIPS OF OTHER VEGETABLE SUBSTANCES,"
upon the condition (amongst others) that I, the said Thomas Brewer, 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 per-
formed, 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 Thomas Brewer, do hereby declare tho
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, that is to say :-
My improvements have reference to the well-known disc turnip cutter, and
consist in so constructing the disc that it will first slice the root, and then by
means of stucks, or other projections, carry the pieces of sliced root through a
series of teeth, knives, or projections arranged in one or more fixed shields or
guards, which are so placed with respect to the revolving disc as to act as a
receptacle for and to retain the cut slices until the projections in the revolving
disc come round, and carry the slices through the teeth or projections in the
shields or guards, causing the root to be completely minced.

page_text: Figures 1, 2, 3, 4, and 5, in the accompanying Drawing represent respec-
tively (1) a side view of the machine complete; (2) an end view of the
same; (3) the cutting disc taken out of the frame; (4) a section of the
same through the diameter; (5) the inside of a top and bottom shield or
casing, which partially covers the disc when in the frame. The letters in the
following description refer to the same parts in all the Figures:-
The machine consists of a vertical metal disc shown partially at A, in
Figure 1, and fully in elevation and section by Figures 3 and 4; the disc
runs on a shaft or spindle B through its centre, which revolves in bearings C
on an iron frame-piece D, which is fixed on the top of the frame or stand E,
A slicing knife is fixed on the front or face of the disc in the position shown
at F, in Figures 3 and 4; the cutting face of the disc forms a portion of one
side of the feeding hopper G, in which the roots are placed to be operated
upon. Figure 3 represents the back, or surface of the disc furthest from the
feeding hopper, and is by preference shown partially ridged as at H, and
partially smooth as at I; J, J, J", are series of projections radiating from
the centre, and may either be cast in the disc or fitted in afterwards; K and
Lare metal shields or casings (fixed on the frame or stand) which partially
cover the disc, and are so placed as to nearly touch the projections J as the
latter revolve; inside these shields are fixed, as shown in Figure 5, a row of
knives M, and rows of projections or stucks N, O, P, and Q, radiating from
the shaft, and which nearly touch the disc; they are so arranged that the pro-
jections J, J', and J", pass in their revolution in spaces intermediate of the
stucks on the shields; R is a fly wheel keyed or screwed on the end of the
shaft B, and S is the handle by which the machine is worked. The feeding
hopper is so made that when the roots are put in they rest against that
portion of the side which is formed of the disc, so that as the latter revolves
the slicing knife or knives cut slices off the roots, which slices pass through
an opening or openings in the disc, and are retained by the knives M
between the shield K and the disc, until the projections J, J, J", como
round, and forces the slices through first the knives M, and then in succession
the projections or stucks N, O, P, and Q, from the last of which they (the
roots) are discharged completely minced or pulped.
Having now described a machine which will effect the object I have in
view, and which embraces the improvements I claim, I would wish it to be
understood that I do not confine myself to this particular arrangement, but
what I do claim is, the adaption of projections on a revolving disc, in con-
nexion with knives or projections, on independent shields or casings, to root

page_text: cutters on the dise principle for further reducing the roots, after the slices are
first cut by the knife or knives on the disc into mince or pulp.
In witness whereof, I, the said Thomas Brewer, liave hereunto set
my hand and seal, this Twenty-eiglith day of December, in the year
of our Lord One thousand eight hundred and fifty-seven.
THOMAS (L.s.) BREWER.
