page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
HARVIE, Engineer, late of Berbice, now of Glasgow, send greeting.
WHEREAS I, the said James Harvie, have by my petition humbly repre-
sented to His present most Excellent Majesty King George the Fourth,
that I have been enabled, by communications made to me by certain persons:
residing abroad, and by long study and application, to effect, GREAT IMPROVE-
MENTS IN THE CONSTRUCTION OF MACHINES COMMONLY CALLED GINNING MACHINES,
AND WHICH ARE EMPLOYED IN SEPARATING COTTON WOOL FROM THE SEEDS," which will.
be of great use, benefit, and advantage to His Majesty's subjects, and that
the said improvements are new, and that the same have not been used
or exercised by any person or persons whatever within His Majesty's
Dominions, to the best of my knowledge and belief, and praying that His
Majesty may be graciously pleased to grant unto me and my executors,
administrators, or assigns, His Majesty's Letters Patent under the Great
Seal of Great Britain, for the sole use, benefit, and advantage of the said
improvements, within that part of His Majesty's United Kingdom called
England, His Majesty's Dominion of Wales, Town of Berwick-upon-Tweed,
and also within His Majesty's Colonies and Plantations abroad, for the term of
fourteen years, pursuant to the Statute in that case made and provided: And
whereas I am about to depart from Great Britain, and that in the event of
His Majesty, from His willingness to give encouragement to all arts and
inventions that may be for the public good, being graciously pleased to con-
descend to my request, and to grant unto me, my executors, administrators,
and assigns, His Royal Letters Patent in the usual form, granting unto me,
+

page_text: the said James Harvie, His special licence, full power and sole privilege and
authority, that I, the said James Harvie, my executors, administrators, and
assigns, and every of them, by myself and themselves, and by my and their
deputy or deputies, servants and agents, and such others as I, or my exe-
cutors, administrators, or assigns, shall at any time agree with, and no other,
from time to time and at all times, for the term of fourteen-years, it will be
necessary for me, in terms of the proviso which is usually contained in Royal
Letters Patent, that I, the said James Harvie, should particularly describe
and ascertain the nature of the said improvements in the construction of
ginning machines, and in what manner the same is to be performed, by an
instrument under my hand and seal, and that I should cause the same to
be enrolled in His Majesty's Chancery within such period as may be pre-
scribed in the said Letters Patent.....
NOW KNOW YE, that I, the said James Harvie, with the view of com-
plying with the said proviso, in the event of His Majesty's being graciously
pleased to condescend to my request, and to grant me His Royal Letters
Patent, do hereby describe and ascertain the nature of the said improve-
ments, and I declare the same to consist in the application of shifting brushes
to the back of the rollers usually employed in ginning machines, by means of
which brushes the cotton on passing through the rollers in the operation of
separating it from the seed is prevented from being carried round the rollers,
whereby it has hitherto been subjected to great injury in its colour and fabric,
and these brushes are to be constructed and affixed to the ginning machine
as follows:-
Prepare a piece of black birch-wood or other hard wood, and let its edge
or thickness be one 'half of an inch, and its breadth two inches and one
quarter of an inch, and let it be of such a length as to fit into the space
between the pinchers, whereby the rollers of the ginning machine to which it
is to be applied are held together. Closely fill the edge of the wood with
bristles, after the manner in which brushes are usually manufactured; at the
distance of one fourth of the length of the brush, make an oblong mortice, seven
eights of an inch in length and one fourth of an inch in breadth, in each end.
of the brush. Sink a brass escutcheon one sixteenth of an inch below the surface"
of the mortices. By passing through the escutcheon and mortice round-headed
screw nails, having flat shoulders, fix the brush to the gin so as the bristles
may come in suitable contact with the rollers; and, when necessary, from the
bristles being reduced in length through continued friction, shift the brushes,
by unscrewing and screwing the nails before described, so as the bristles may
be continued at all times in suitable contact with the rollers.
