page_text: WHITHAM'S SPECIFICATION.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
WHITHAM, of Sheffield, in the County of York, Manufacturer of Spindles,
send greeting.
WHEREAS His present Majesty King George the Third, in and by His
Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Eighth day of April now last past, for Himself, His heirs
and successors, did give and grant unto me, the said George Whitham, my
exors, adiiors, and assigns, His special licence, full power, sole privilege and
authority, that I, the said George Whitham, my cñors, adññiors, and assigns,
and every of them, by myself and themselves, or by my and their deputy or
deputies, servants or agents, or such others as I, the said George Whitham,
my exors, adññors, and assigns, should at any time agree with, and no others,
from time to time and at all times thereafter 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, my Invention of
"CERTAIN MACHINERY FOR GRINDING, GLAZING, AND DRESSING SMALL COTTON AND
WOOLLEN SPINDLES, FOR SPINNING ON JENNEY, BILLEY, AND MULE, OR OTHER KIND
OF MACHINE FOR FINE WORK;" in which said Letters Patent there is contained a
proviso obliging me, the said George Whitham, particularly to 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
to cause the same to be inrolled in His Majesty's High Court of Chancery
within two calendar months next immediately after the date of the said
recited Letters Patent, as in and by the same, reference being thereunto had,
will more fully appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
George Whitham, do hereby describe and ascertain the nature of my said

page_text: Invention, and in what manner the same is to be performed, by the Plan or
Drawing in the margin or at the head of these Presents, and the following
description thereof, that is to say :-
of
See Fig. 1.-A firm frame A, A, is made of wood, metal, or other materials,
and placed in such position, direction, or inclination, as may be found most
convenient, in front of the grinding or mill stone herein-after mentioned.
Upon the same frame A, A, is placed a moveable or sliding frame B, B, of
iron, steel, or other metal. C, C, are side or regulating screws to keep the
frame B, B, in its position fronting to the grinding or mill stone P. At the
upper end of the frame A, A, is a pulley over which a cord passes, one end of
which is attached to the frame B, B, and at the other is suspended a weight
power sufficient to retain back the moveable or sliding frame B. B. when
put back by the hand with lever D. E is a bar of iron, steel, or other
metal fixed within the frame B, B, near the low end of which, at F, is a hole
which admits of the end of lever D passing through it, and which afterwards
enters a corresponding hole in a piece of iron, steel, or other metal fixed in the
lower frame A, A, underneath. When the lever D is inserted in the above-
mentioned places, the sliding or moveable frame can be worked backwards and
forwards with facility. c, c, c, c, are projecting pieces of iron, steel, or other
metal, fixed in front of the low end of the moveable or sliding frame B, B. A
semicircle is made in each to support the spindle during the process of grind-
ing, glazing, or dressing. G, G, are pieces of curved iron, steel, or other
metal, fixed on the outside, at the low end of the moveable or sliding
frame B, B, which serve as rests to the spindle when the process of grinding,
glazing, or dressing is performed by the hand without the application of the
pulley H. Pulley II is attached to the sliding or moveable frame B, B, by a
round pin or axis K, of steel, iron, or other metal, on which it moves round,
at the same time it admits of its being detached from the moveable or sliding
frame B, B, or of its being thrown back on the stay or rest L, whenever the
application of it may not be deemed necessary. Within the pulley H is fixed
a piece of iron, steel, or other metal, with a transverse notch or gate, the same
being perforated with a hole of a size sufficient to admit of a spindle 'being
passed through it; a dog head or other clamp of steel, iron, or other metal,
being previously fixed on the spindle by a screw or otherwise, may then be
passed through the hole in the centre of the pulley H. The dog head or clamp
fits within the above notch or gate in .pulley H, by which means the spindle is
placed in an horizontal position, at the same time moving round during the
progress of grinding, glazing, or dressing. At the upper end of the frame A, A,
is an axle M, with two pulleys O, N; one end is attached to frame A, and the
other to an upright supporter T, of wood, metal, or other materials. P is a

page_text: grinding or mill stone; Q, the axle of the same, with R, its pulley; and S is
a smaller pulley fixed by the side of the same, from which a band or gear
passes over the pulley O on axle M. Another corresponding band or gear
passes from pulley N over pulley H, which gives the requisite motion.
Lever D is then inserted in the hole F, in the sliding or moveable frame B, B,
a spindle being previously inserted in pulley H, as before described; the frame
is then drawn by the hand, with lever D towards the face of the grinding or
mill stone P, by which means spindles may be ground, glazed, or dressed with
a greater degree of accuracy than by any other practice or method heretofore
known.
Sec Fig. 2. When the pulley H is thrown back on stay or rest L, or de-
tached altogether from the sliding or moveable frame B, B, as before described,
the spindles may then be turned by hand on the small curved rests G, G,
and ground, glazed, or dressed by the application of the sliding or moveable
frame B, B, independently of pulley H. For the Patentee by no means confines
himself entirely to the use of pulley H; but to the principle of grinding,
glazing, and dressing of small cotton or woollen spindles by means of the
sliding or moveable frame B, B, which may be constructed in various ways,
and of different materials, and the principle will remain in effect the same.
In witness whereof, I have hereunto set my hand and seal, this Second
day of June, in the year of our Lord One thousand eight hundred
and eighteen.
GEORGE WHITHAM. (L.S.)

Lord the King in His Chancery, and acknowledged the Specification afore-
said, and all and every thing therein contained and specified, in form above
written. And also the Specification aforesaid was stampt according to the
tenor of the Statute made for that purpose.
