Finsbury Park, in the County of Middlesex, N., for the Invention
of " AN IMPROVED ROMADY K
:
PROVISIONAL SPECIFICATION left by the said Christopher Fabian
Bower at the Office of the Commissioners of Patents, with his
Petition, on the 3rd July 1874.
. I, OBISTOPHER FABIAN BOWER, No. 14, Perth Road, Finsbury Park,
in the County of Middlesex, N., do hereby declare the nature of the said
Invention for "AN IMPROVED ROTARY KNIFE CLEANER," to be as follows:-
On the top of the machine a slide is wroked between two groves
which carries a shield or protector for each knife, preventing them from
oscillating, twisting, or being injured.
There is a stop to fix the slide when in operation; instead of single
leathers they are double.
Stans are placed on the spindle urssenting the dises furm canarine

Office on the 2nd Jannary 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHRISTOPHER
FABIAN BOWER, No. 14, Perth Road, Finsbury Park, in the County of
Middlesex, N., send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of July, in the year of our Lord One
thousand eight hundred and seventy-four, in the thirty-eighth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Christopher Fabian Bower, Her special license that I, the
said Christopher Fabian Bower, my exccutors, administrators, and
assigns, or such others as I, the said Christopher Fabian Bower, 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
ROTARY KNIFE CLEANER," upon the condition (amongst others) that I, the
said Christopher Fabian Bower, my exccutors 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 Inven
tion, 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 Christopher Fabian Bower, do hereby
declare the nature of the said Invention, and in what manner the samo
is to be performed, to be particularly described and ascertained in and
by the following statement thereof, that is to say:—
On the top of tho machine a slide is worked between two grooves,
which slide carries a shield or protector for each knife, which, on being
pressed up against the knife handles after they have been inserted into
the machine, hold the knives firmly in the position required; thus
preventing them from oscillating or twisting, and thus either being
themselves injured or cutting the surfaces of the revolving discs.

page_text: When the slide with the shields has been pressed home it is retained
in position by a suitable catch.
As the rubbing surfaces of the revolving discs of rotary knife cleaners
wear away the discs may be brought together by being screwed on to
the spindle; but with inexperienced persons they are often screwed tho
wrong way, thus getting them out of position, which usually ends in
damage to the machine. To prevent this I provide stops on the spindle,
so as to prevent the discs from being screwed back.
And in order that my Invention may be clearly understood, and
readily carried into effect, I will proceed to describe the same with tho
aid of the accompanying Drawings, reference being had to the letters
and figures marked thereon, and in which Figure 1 is an clevation,
partly in section, of an ordinary rotary knife cleaner with my improve-
ments attached; Figure 2, a horizontal section through the lino a, b,
Figure 1; Figure 3 an end clevation; and Figures 4 to 10 enlarged
views of detail.
A is my improved slide, which works on the top of the machine
between grooved guides B, and carrying a shield C for each knife the
machine is capable of holding at one time, which shields are for the
purpose of steadying the knives while they are being cleaned, and the
shields being all attached to the one slide A are all moved forward or
backward by the one movement of the slide.
In Figure 1 the shields are shewn pressed forward on to the knife
handles, as also in the enlarged part sectional elevation at Figure 4,
shewn also in transverse sectional elevation at Figure 5, and in plan at
Figure 6. At Figure 7 however, which is also a part sectional elevation,
the shield is shewn drawn back away from the knife handle, the knife
not being shown; Figure 8 is a plan of Figure 7. The slide and shields
being drawn back, as shown at Figures 7 and 8, the knives are inserted,
as shewn at Figures 1 and 4, and the slide and shields pressed forward
until the knives are thereby firmly locked in position when the slide is
fixed by the catch D, constructed as shown with inclined surface, so as
to compensate for varying size of knife handles.
When the knives have been cleaned the slide and shields are drawn
back and the knives removed.
The shield C may terminate at the bottom with the slide, as shown
at Figure 4, or the back thereof may be extended beneath the slide, as

page_text: shown at Figure 7, so as to give a larger surface for steadying the knifo
against.
For preventing the discs from being screwed the wrong way by
inexperienced persons I attach to the spindle E a ratchet F and pawl G,
the ratchet wheel being keyed on to the spindle and the pawl attached
to the face of the nut H, and to prevent the nut receding from tho
ratchet wheel as it is advanced (by screwing) on the spindle, and thus
prevent the pawl from leaving the ratchet wheel, the face of the nut
His recessed, and the ratchet wheel, which is made rather wide, let
partly into the recess, see Figures 2, 9, and 10, Figure 9 being an
enlarged face view, and Figure 10, a transverse vertical central section.
In some cases, and particularly where cheapness is much an object,
instead of the ratchet wheel and pawl I simply fix a collar on the spindle
between the bearings I and the nut H, so as to prevent the discs from
receding further back than originally set.
Having thus particularly described and ascertained the nature of this
my said Invention, and the manner in which the same is to or may be
performed, I claim as my Invention, to be secured by the herein-before
in part recited Letters Patent, the improved knife cleaner, substantially
as herein-before set forth and described and illustrated in the accom-
panying Drawings.
In witness whereof, I, the said Christopher Fabian Bower, have
hereunto set my hand and seal, this Second day of January,
in the year of our Lord One thousand cight hundred and seventy-
five.
