IMPROVEMENTS IN MACHINERY OR APPARATUS FOR PREPARING COTTON, WOOL, OR OTHER FIBROUS SUBSTANCES. TO BE SPUN
Year: 1857

page_text: LETTERS PATENT to William Crighton, of the City of Manchester, in the
County of Lancaster, Machinist, and Peter Foxcroft, of. Pendleton, in the
said County, Manager, for the Invention of "IMPROVEMENTS IN MACHINERY
OR APPARATUS FOR PREPARING COTTON, WOOL, OR OTHER FIBROUS SUBSTANCES.
TO BE SPUN."
Sealed the 31st July 1857, and dated the 21st April 1857.
PROVISIONAL SPECIFICATION left by the said William Crighton and
Peter Foxcroft at the Office of the Commissioners of Patents, with
their Petition, on the 21st April 1857.
We, WILLIAM CRIGHTON, of the City of Manchester, in the County of Lan-
caster, Machinist, and PETER FOXCROFT, of Pendleton, in the said County,
Manager, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN MACHINERY OR APPARATUS FOR PREPARING COTTON, WOOL, OR OTHER
FIBROUS SUBSTANCES TO BE SPUN," to be as follows:-
To the Derby doubler or lap frame we place an open table or frame over
any convenient number of cans; in this table or frame we place or fix the
requisite number of pullies or rollers, so that there shall be one over each can;

page_text: or we place a number of grooved shafts across the said table or frame, or any
description of guide, so that the sliver from each can shall pass over each of
the pullies, or rollers, or grooved shafts, or other guide, and be thus conveyed
to the calender rollers of the ordinary Derby doubler. The said pullies,
rollers, grooved shafts or guides receive the necessary rotary motion by means
of shafts, straps, or any suitable contrivance or contrivances from the driving
apparatus of the engine. But if desirable the said guides may be motionless,
and we may also place a perforated plane or table over the said frame, so that
each sliver may pass through one of the perforations and be thus conveyed to
the calender rollers; but we consider the former plan preferable.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Crighton and Peter Foxcroft in the Great Seal
Patent Office on the 21st October 1857.
TO ALL TO WHOM. THESE PRESENTS SHALL COME, we, WILLIAM.
CRIGHTON, of the City of Manchester, in the County of Lancaster, Machinist,
and PETER FOXCROFT, of Pendleton, in the said County, Manager, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of April, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twentieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said William Crighton and Peter Foxcroft, Her special license that we, the
said William Crighton and Peter Foxcroft, our executors, administrators, and
assigns, or such others as we, the said William Crighton and Peter Foxcroft,
our executors, administrators, and assigns, should at any time agree with, and
no others, from time to time, and at all times thereafter during the term
therein expressed, should. and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel-
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN MACHINERY OR
APPARATUS FOR PREPARING COTTON, WOOL, OR OTHER FIBROUS SUBSTANCES TO BE
SPUN," upon the condition (amongst others) that we, the said William Crighton
and Peter Foxcroft, by an instrument in writing under our hands and seals,
or the hand and seal of one of us, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was to be

page_text: performed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that we, the said William Crighton and-Peter-Foxcroft,
do hereby declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and
by the following statement (that is to say) :-
We apply to the ordinary Derby doubler or lap machine an open table or
feeding frame, under which we place any convenient number of cans contain-
ing the slivers, which are guided to the calender rollers by pullies, forks,
shafts, or other suitable guides placed upon the open table.
The said guide pullies, shafts, or forks may be used either separately or
conjointly. When shafts or rollers are employed they may be either grooved
or plain, and they may also be either stationary or have a revolving motion,
any convenient number of which may be employed; or we place a perforated
plane or table over the said open table, so that each sliver may pass through
one of the perforations, and be thus guided to the calender rollers.
The manner in which our said Invention is to be performed will be clearly
understood by reference to the accompanying Sheet of Drawings, and the
letters of reference thereon, in which Figure 1 is a longitudinal elevation of a
Derby doubler or lap machine having our feeding frame and guides attached;
and Figure 2 a plan of the same. a represents the ordinary Derby doubler;
b, the open table or feeding frame; c, the cans; d, the slivers, which are con-
veyed to the calender rollers over the shafts e, and also pass through the forks
or guides f, placed upon the rods g. It will be observed, that according to the
positions of the cans some of the slivers may touch the under parts of the
shafts e as well as the upper.
The advantages of our open table with the necessary guides are to prevent
the excessive crowding of the cans, and the consequent inconvenience and loss
of time in changing or removing them, and also the great facility for detect-
ing and repairing breakages.
Having thus fully described the nature of our said Invention, and the
manner in which the same is to be performed, we desire it to be distinctly
understood that we do not confine ourselves to the exact details herein set
forth, as such may be varied or modified without departing from the principle
thereof; but we claim as our Invention, and which, to the best of our know-
ledge and belief has not been hitherto used within the realm, the use or
application to the ordinary Derby doubler or lap machine of an open table or

page_text: feeding frame with guide pullies, shafts, forks, or other suitable guides, used
either separately or conjointly, and the shafts or rollers either grooved or plain,
as such improvements are herein described, and illustrated in the accompanying
Sheet of Drawings.
In witness whereof, we, the said William Crighton and Peter Foxcroft, 5
have hereunto set our hands and seals, this Twentieth day of October,
in the year of our Lord One thousand eight hundred and fifty-seven.

named William Crighton and Peter Fox-
