Year: 1861

page_text: LETTERS PATENT to Antoine Garzend, of 29, Boulevart St. Martin, Paris,
Gentleman, for the Invention of "A NEW OR IMPROVED APPARATUS FOR
CHITTING UP AND REDUCING DYE AND OTHER WOOD."
Sealed the 28th January 1862, and dated the 12th August 1861.
PROVISIONAL SPECIFICATION left by the said Antoine Garzend at the
Office of the Commissioners of Patents, with his Petition, on the 12th
August 1861.
I, ANTOINE GARZEND, of 29, Boulevart St. Martin, Paris, Gentleman, do
hereby declare the nature of the said Invention for "A NEW OR IMPROVED
APPARATUS FOR CUTTING UP AND REDUCING DYE AND OTHER WOOD," to be as
follows:-
My Invention relates to improved apparatus for cutting up and reducing
dye & other woods. For this purpose I employ a kind of cylinder having the
form of an Archimedian screw, on the projections of which cutters are fixed in
any suitable manner. By imparting a rapid rotary motion to the cutter
cylinder, the wood as it is fed into the apparatus will be cut up. It will also
be understood that by augmenting or diminishing the pitch of the Archimedian
screw which forms the cutter cylinder, or by varying the number of cutters on
the cylinder, the wood may be reduced either to small blocks, shavings, or
chips, or into flat strips, or wood dust.
This apparatus is also suitable for cutting up wood of all dimensions. For

page_text: this purpose the wood under operation is fixed on a carriage, which is caused
to advance gradually towards the cutters by means of a screw & nut. The
movement of the carriage may be varied at will, & is further dependent on the
movement of the cutter cylinder. The cutter cylinder may receive motion
from any motive power by the intermediation of wheel gearing, & besides its
rotating movement it may have an up-&-down movement, so as to raise or
lower the tools for the purpose of more completely cutting up the wood. This
vertical movement of the tool carrier is independent of its other movements, &
is effected by hand by turning a winch, on which is wound cords which carry
the shaft of the cutter cylinder, which shaft slides in circular grooves cast in
the frame of the apparatus.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Antoine Garzend in the Great Seal Patent Office on the
7th February 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ANTOINE
GARZEND, of 29, Boulevart St. Martin, Paris, Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twelfth day of August, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Antoine Garzend, Her special licence that I, the said Antoine Garzend, my
executors, administrators, and assigns, or such others as I, the said Antoine
Ġarzend, 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 "A NEW OR IMPROVED APPARATUS FOR
CUTTING UP AND REDUCING DYB AND OTHER WOOD," upon the condition (amongst
others) that I, the said Antoine Garzend, 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 Inven-
tion, and in what manner the same was to be perforined, 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 Antoine Garzend, do hereby declare the
nature of my said Invention, and in what manner the same is to be performed,

page_text: to be particularly described and ascertained in and by the following statement,
reference being had to the annexed Drawings, and to the letters of reference
marked thereon, that is to say:-
My Invention relates to improved apparatus for cutting up and reducing
dye and other woods. For this purpose I employ a tool carrier or kind of
cylinder, having the form of an Archimedian screw, on the projections of which
cutters are fixed in any suitable manner. By imparting a rapid rotary motion
to the cutter cylinder, the wood as it is fed into the apparatus will be instantly
cut up. It will be also understood that by augmenting or diminishing the
pitch of the Archimedian screw which forms the cutter cylinder, by bringing
more apart or more closely the cutters on the cylinder, the wood may be
reduced either to small blocks, or shavings, or chips, or into flat strips, or
into dust.
This apparatus is also suitable for cutting up wood of all dimensions. For
this purpose the wood under operation is fixed on a carriage, which is caused
to advance gradually towards the cutters by means of screw and nut. The
movement of the carriage may be varied at will, and is further dependent on
the movement of the cutter cylinder. The cutter cylinder may receive motion
from any motive power by the intermediation of wheel gearing, and besides its
rotating movement it may have an up-and-down movement, so as to raise or
lower the tools for the purpose of more completely cutting up the wood. This
vertical movement of the tool carrier is independent of its other movements,
and is effected by hand by turning a winch, on which is wound a cord which
supports the shaft of the cutter cylinder, which shaft slides in circular grooves
cast in the frame of the apparatus.
I have represented the apparatus of my Invention in the annexed Drawings,
wherein Fig. 1 shows an end view; Fig. 2, a side longitudinal view; and
Fig. 3, a plan of the said apparatus; and in these three Figures the same
letters of reference indicate the like parts where they recur.
The apparatus consists of a cast-iron or other framing for supporting a
carriage b, upon which is fixed by means of bolts the piece of dye wood under
operation; c is an Archimedian screw or tool carrier of cast iron, or other
material; d, d, are the tools for reducing the dye wood. The Archimedian
screw may be placed in the middle of shaft e, or on one of its ends. The
screw has on the sharp edge of its thread an opening, into which are wedged
the tools d, d. These tools, the whole series of which is firmly secured at both
ends of said opening by a screw, are separated from each other by small
wedges of indefinite size, so as to be equally apart, as may be seen distinctly
at Fig. 1. The object of this arrangement is to obtain chips of regular

page_text: thickness and dimensions desired. With this whole series of tools I can obtain
either dust or chips by suitably varying either the nature of the tools or their
arrangement, or the thread of the Archimedian screw upon which they are
set. The shaft upon which the screw is carried is made to rise or lower at
will along the slide f by means of the cord g, which is wound upon the shaft h,
and hooked up in the ring i, and this movement is effected through the
wrench. The wedges k can be so combined as to give the shaft e all possible
directions; the whole series of said wedges is held in position by means
of screws 1, 1. The pulleys m & n, mounted upon the shaft o, and the
pinion p keyed upon the same shaft, and gearing with the wheel q, operate
the Archimedian screw. The crank r, through the medium of the connecting
rods & t, operates the ratchet u by means of a dog fitted for the purpose.
The ratchet u by successive movements rotates the shaft v, which transmits
through the two beveled pinions wits own movement to the screw x, which
engages the nut fitted beneath the carriage b. On the carriage is secured
the piece of wood under operation; this is secured by means of headstocks; not
represented, or otherwise. The pulley acts upon the two pullies 1 & 2, in
order to bring the carriage back rapidly.
Having thus described the nature of my Invention, and the manner in
which the same is to be carried into effect, I wish it to be distinctly understood
that what I claim as being of my Invention is,-
First, the cutting up and reducing of dye wood by means of a cutter
cylinder, as described, the sharp parts of which are arranged helically, and
operate in the manner and for the purpose herein specified.
Secondly, the arrangement of all the mechanical parts, as in the specimen
or illustration represented.
In witness whereof, I, the said Antoine Garzend, have set my hand and
seal, this Thirty-first day of January, in the year of our Lord One
thousand eight hundred and sixty-two.
