Year: 1807

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
BROWN, of the Parish of Saint Andrew Hubbard, in the City of London,
Stationer, send greeting.
WHEREAS His most Excellent Majesty King George the Third did,
by His Letters Patent under the Great Seal of the United Kingdom
of Great Britain and Ireland, bearing date at Westminster, the Second
day of June, in the forty-seventh year of His reign, give and grant
unto me, the said John Brown, my exors, admors, and assigns, His
especial licence, full power, sole privilege and authority, that I, the
said John Brown, my exors, admors, and assigns, during the term of years
therein mentioned, should and lawfully might make, use, exercise, and vend,
within England, Wales, and the Town of Berwick-upon-Tweed, my Invention
of "CERTAIN IMPROVEMENTS IN THE CONSTRUCTION OF A PRESS FOR PRINTING BOOKS
AND OTHER ARTICLES, PART OF WHICH MAY BE APPLIED TO PRESSES NOW IN COMMON
Use;" in which said Letters Patent there is contained a proviso obliging me.
the said John Brown, by an instrument in writing under my hand and seal,
to cause a particular description of the nature of my said Invention, and in
what manner the same is to be performed, to be inrolled in His Majesty's
High Court of Chancery within one calendar month after the date of the
said recited Letters Patent, as in and by the same, relation being thereunto
had, may more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
John Brown, do hereby declare that my said Invention is described in the
Drawings and description thereof hereunto annexed :-
In witness whereof, I, the said John Brown, have hereunto set my hand
and seal, the Second day of July, in the year of our Lord One
thousand eight hundred and seven.
Figure 1 is a press made of cast iron (or any other fit material), which is
cast with Figure 2 in one body. Fig. 3 is a bed made of cast iron or any
other proper material, which must be faced true for the types to lay on, as at
Fig. 10. Fig. 4 is the follower which gives the pressure on the types, and is
fixed to the screw. Fig. 5 is a guide for the screw, with a hole in it to receive
the blank part of the screw, being screwed or otherwise fastened to the side
of the press. Fig. 6 is a bevil wheel and pinion, with a handle to give motion
to the same, fixed on a spindle or shaft on the top of which, Fig. 7, is a
rigger sheve or cylinder, with a catch or clutch to throw it out of geer when
required. The rigger being fixed on a round axis, the clutch on a square,
and the rope fixed to a lever on the screw, Fig. 8, the rope keeling or winding
round the rigger sheve or cylinder, after the pressure is given, strikes out the
catch, and lets the screw revolve back on the round axis. by means of weight
or spring. Fig. 10 is a cast-iron bed or platform, being placed true for the
type to lay on. This cast-iron bed slides out below the roller or cylinder Fig. 11,
which roller or cylinder revolves round and feeds the types with ink. This
roller or cylinder is covered with flannel or any other proper elastic sub-
stance, and then is covered with parchment or vellum or other proper materials,
to prevent the ink from soaking too far in, and likewise to give it a spring, and
afterwards is covered with superfine woolen cloth (or any other fit material),
additionally sheared, if required, for the purpose of receiving the ink to supply
the types.. Fig. 12 is a large barrel or cylinder, and also a small barrel or cylinder.
The large barrel or cylinder having received the ink from a trough Fig. 16,
underneath it, the small barrel or cylinder rolls on the large barrel or cylinder,
and distributes or spreads out the ink on the face of the large barrel, Fig. 12;
or it may be necessary with the small barrel or cylinder occasionally to use a
brush to distribute the ink or lay the ink on the large barrel. The large
barrel or cylinder feeds the barrel or cylinder Fig. 11 with ink, and the barrel
or cylinder No. 11 revolves round and feeds the types by the motion or
movement of the spindle which moves the bed Fig. 10. .Fig. 13 is a platform,
on which the types are laid, and the platform or types slide in and out under the
screw by turning the handle and spindle Fig. 15, which gives motion to the large

page_text: and small barrels or cylinders Fig. 12, and also to Fig. 11, which feeds the
types with ink. Fig. 14 is a platform for a loose moveable friskett, which
friskett is connected with and slides in and out at the ends of the iron
bed Fig. 4, for the purpose of conveying the paper over the types. Fig. 15
is a spindle and a handle for moving the bed Fig. 10, with the types thereon,
which handle and spindle give motion by means of a strap or any other
convenient thing to the barrels or cylinders Fig. 12 and 11. I also apply the
barrels or cylinders Fig. 11 and 12 (being my principal improvement) to
presses now in common use, by means of a fly wheel and traddle, which give
motion to the two barrels or cylinders No. 12, and distribute the ink which
is received by Fig. 11 barrel or cylinder as above specified, and which barrel
or cylinder may be rolled over the types to feed them with ink, either by the
motion of the hand or fly wheel, or in various ways well understood by every
competent workman.
My first improvement is on the press, my second improvement consists in
using barrels or cylinders for feeding the types with ink, and my third improve-
ment consists in the loose friskett, and the mode of using it.
JOHN BROWN. (L.S.)
