CERTAIN IMPROVEMENTS IN SPINNING MACHINES
Year: 1830

page_text: DANDS, OI Liverpool, Merchant, end greeting.
WHEREAS, in consequence of a communication from a certain Foreigner
residing abroad, I am in possession of an Invention of "CERTAIN IMPROVEMENTS
IN SPINNING MACHINES," and whereas His present most Excellent Majesty
King William the Fourth, by His Letters Patent under the Great Seal of
Great Britain, bearing date at Westminster, the Twentieth day of November,
in the first year of His reign, did, for Himself, His heirs and successors, give
and grant unto me, the said Thomas Sands, His especial licence that I, the
said Thomas Sands, my exors, admors, and assigns, or such others as I, the
said Thomas Sands, my exors, admors, or 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, "the said
Invention;" in which said Letters Patent is contained a proviso, obliging me,
the said Thomas Sands, by an instrument in writing under my hand and seal,
particularly to describe and ascertain the nature of the said Invention, and in
what manner the same is to be performed, and to cause the same to be
enrolled in His said Majesty's High Court of Chancery within six calendar
months next and immediately after the date of the said recited Letters Patent,
as in and by the same, reference 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
Sands, do hereby declare the nature of the said Invention to consist in
applying to the bobbins the whir or pulley, which is usually fixed on the
spindle, and in other arrangements connected with this change in the position
of the whir. And in further compliance with the said proviso, I, the said
Thomas Sands, do hereby describe the manner in which the said Invention is
to be performed by the following description thereof, reference being had to
the Drawing annexed, and to the figures and letters marked thereon, that is
to say:-
:
DESCRIPTION OF THE DRAWING.
Figure 1 represents a spindle and flyer, a bobbin, a whir, and the rails or
frames connected therewith. A, A, A, A, represent the spindle and flyer, on
which spindle, it will be seen, there is no whir; B is the bobbin; and C
(colored yellow for distinction) is a hollow tube, with a flat boss D at the
lower part of it, fastened to the lifting rail. The bobbin turns round this tube
supported by the boss, and the spindle passes through the tube, resting as
usual on the bottom rail, and thus having a motion wholly independent of the
bobbin. E is the whir, resting on the boss D, and turning loosely on the
hollow tube C; the bobbin rests on this whir, which catches in it by means of
a tooth or clutch, as shown in the Figure, in the nature of a small clutch box;
if motion be given to the whir by means of the ordinary band, it will be
evident that the bobbin will be driven round at any required speed, while the
thread, which is shown by the red line f, will drag round the spindle and flyer;
and in order that the bobbin and spindle shall not move at equal speed, the
small piece of leather G and weight H are applied to cause friction at the
lower end of the spindle. The leather is merely nailed on the bottom rail,
and having a hole pierced in it, the lower end of the spindle is passed through
this hole, and the weight causes a constant pull at one side of the hole against
the spindle, and, of course, according to the size of the weight, so will the
motion of the spindle be accelerated or retarded. Figure 2 is only a side view
of this contrivance.
Now whereas I claim as the Invention aforesaid the application of the
whir to the bobbin instead of the spindle by means of the hollow tube, boss,
and clutch, as hercin-before described, as also the mode of regulating the speed
of the flyer by means of the leather and weight applied as herein-before also
described, and such my Invention being, to the best of my knowledge and
belief, entirely new and never before used within that part of IIis said
Majesty's United Kingdom of Great Britain and Ireland called England, His

page_text: said Dominion of Wales, or Town of Berwick-upon-Tweed, I do hereby
declare this to be my Specification of the same, and that I do verily believe
this my said Specification doth comply in all respects fully and without
reserve or disguise with the proviso in the said herein-before in part recited
Letters Patent contained, wherefore I do hereby claim to maintain exclusive
right and privilege to the said Invention.
In witness whereof, I, the said Thomas Sands, have hereunto set my
hand and seal, this First day of January, in the year of our Lord One
thousand eight hundred and thirty-one.
