page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, 'ROBERT
BURN, of the City of Edinburgh, in the County of Midlothian, send
greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the second day of Decem-
ber, in the twelfth year of Her reign, did, for Herself, Her heirs and succes-
sors, give and grant unto me, the said Robert Burn, my exors, admors, and
assigns, Her especial licence, full power, sole privilege and authority, that I,
the said Robert Burn, my exors, admors, and assigns, or such others as I, the
said Robert Burn, my exors, admors, and assigns, should at any time agree
with, and no others, from time to time and at all times during the term of
years therein expressed, should and lawfully might make, use, exercise, and
vend, within England, Wales, and the Town of Berwick-upon-Tweed, and in
the Islands of Guernsey, Jersey, Alderney, Sark, and Man, and also in all Her
said Majesty's Colonies and Plantations abroad, my Invention of "AN IM-
PROVED ROLLER GIN USED IN SEPARATING THE SEED FROM COTTON;" in which said

page_text: Letters Patent there is contained a proviso that I, the said Robert Burn, shall
cause a particular description of 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, to be enrolled-in Her said Majesty's High Court of Chancery,
within six calendar months next and immediately after the date of the said in
part recited Letters Patent, as in and by the same, reference being thereunto
had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Robert Burn, do hereby declare that the nature of my Invention, and the
manner in which the same is to be performed, are particularly described and
ascertained in and by the following statement thereof, reference being had to
the Drawing hereunto annexed, and to the figures and letters marked thereon,
that is to say :-
My Invention consists of the application to the roller gin of a brush fan i,
Figures 2, 3, & 5, and steel roller e, Figure 5, with moveable steel bearings
h 1, Figure 2, and fixed steel bearings e 2, Figure 1, applied to steel roller
and wood roller and endless cloth or apron with card teeth n, Figures 1, 2,
and 5. By the use of the brush fan i, Figures 2, 3, & 5, the cotton is freed
from all extraneous materials more completely than by the present roller gin.
And by the use of the steel roller and steel bearings h 1, Figure 2, and e 2,
Figure 1, instead of brass or iron or wood bearings, as now used, the roller
gin lasts longer, and works with greater accuracy. And by the use of the card-
ing cloth n, Figures 1, 2, and 5, the seed cotton is supplied to the gin more
regularly than by the hand, and at less cost than by manual labour.
The other parts of the machine consist of a cast-iron framing a, Figures
1, 2, 3, and 4; fast and loose pulleys b, Figures 1 and 3 & 4; right-hand
driving wheel and shaft c, Figures 1 and 3 & 4; brush pinion wheel d,
Figures 1 and 3; steel roller pinion wheel e, Figures 1 and 3; left-hand
driving wheel f, Figure 4; stud wheel g, Figures 2 and 4; wood roller pinion
wheel h, Figures 2 and 4; fly wheel j, Figures 2 and 3; sheet-iron cover k,
Figures 1 and 4; meter wheels 1, Figures 2, 3, and 4; screw wheel m,
Figures 1, 2, and 3; upright screw, gearing with moveable steel bearings
of the wood roller o, Figures 1 and 2: to which parts no claim is made.
In witness whereof, I, the said Robert Burn, have hereunto set my
hand and seal, this Twenty-third day of May, in the year of our Lord
One thousand eight hundred and forty-nine.
ROBERT (L.B.) BURN..
