Year: 1823

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
HORNE, the younger, of Birmingham, in the County of Warwick, Brass-
founder, send greeting.
WHEREAS His most Excellent Majesty King George the Fourth, did, by
His Letters Patent under the Great Seal of that part of the United Kingdom
of Great Britain and Ireland, called England, bearing date at Westminster, the
Ninth day of December, One thousand eight hundred and twenty-three in
the fourth year of His reign, give and grant unto me, the said Thomas
Horne, my exors, admors, and assigns, His especial licence, full power, sole
privilege and authority, that I, the said Thomas Horne, my exors, adñiors,
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
MANUFACTURE OF RACK PULLIES IN BRASS OR OTHER METALS;" in which said
Letters Patent there is contained a proviso, that if I, the said Thomas Horne,
shall not particularly describe and ascertain the nature of my said Invention,
and in what manner the same is to be performed, by an instrument in
writing under my hand and seal, and cause the same to be inrolled in His
Majesty's High Court of Chancery within six calendar months next and
immediately after the date of the said Letters Patent, that then the said
Letters Patent, and all liberties and advantages whatsoever thereby granted,
shall utterly cease, determine, and become void, as in and by the same, relation
being thereunto had, will more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Thomas Horne, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, are particularly described
and ascertained in and by the Drawing hereunto annexed, and the following
description thereof (that is to say) :-
My improvements in the manufacture of rack pullies in brass or other
metals consists in forming plates of such metal for the construction of the
pulley rack, with suitable clevations and indentations by means of a pair of
rollers, the periphery of one being smooth, the other indented or grooved. In
order to form these pulley racks, I first take ingots of metal and roll them
into strips of about the thickness of one-eighth of an inch; after having thus
prepared the metal in strips, I then pass those strips between a pair of rollers,
the upper one being smooth, the lower one with an indented groove, or visa
versa. The strip by this process assumes the appearance shown at Fig. 1 in
the accompanying Drawing, having steps or knotches at certain distances up
the middle; I next cut out the extreme form of the rack pulley plate by
means of a cutting press, and produce the piece as shewn at Fig. 2; after the
plate has been so indented and cut I turn over the edges upon a mandral by
means of a swage or other tools, or by a mallet in the ordinary way, by which
contrivances the pulley rack is formed with a smooth or level back, and per-
fected, as shown at Fig. 3. I have described the indentations of my improved
pulley racks as made by means of a pair of rollers, the one plain, the other
indented, which mode I prefer, but I can also produce a similar article by
means of a stamping or pressing apparatus. By these contrivances I can
'make pulley racks out of sheet or rolled metal in one piece without being con-
'nected in two parts, with level or smooth backs, though not so advantageously
by stamping or pressing as by the rollers, each of which modes I therefore
'claim as my Invention, observing that pulley racks with indented backs have
been made out of sheet or rolled metal in one piece by stamping, but those
with flat or level backs made out of sheet metal in one piece, either rolled,
'stamped, or pressed, are the articles which I hereby clam to have invented.
In witness whereof, I, the said Thomas Horne, have hereunto set my
hand and seal, this
