IMPROVEMENTS IN MACHINERY OR APPARATUS FOR SPINNING COTTON AND OTHER FIBROUS MATERIALS
Year: 1862

page_text: LETTERS PATENT to James Wood Baker, of Bury, in the County of
Lancaster, Cotton Spinner, for the Invention of "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR SPINNING COTTON AND OTHER FIBROUS
MATERIALS."
Sealed the 6th March 1863, and dated the 13th December 1862.
PROVISIONAL SPECIFICATION left by the said James Wood Baker
at the Office of the Commissioners of Patents, with his Petition, on the
13th December 1862.
I, JAMES WOOD BAKER, of Bury, in the County of Lancaster, Cotton Spinner,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR SPINNING COTTON AND OTHER FIBROUS MATERIALS,"
to be as follows:-
This Invention relates principally to stand or self-acting mules, and con-
sists in giving a positive motion to the tin roller which drives the spindles
by means of toothed gearing. I connect the rim shaft by spur or bevil
gear with a toothed wheel extending the length of the draw, and placed
from end to end of the headstock, so that a spur wheel attached to the
carriage shall slide backwards and forwards in the long wheel, and be con-
stantly in gear. To the shaft of the spur wheel is fixed a bevil wheel
gearing into another bevil wheel on the tin roller shaft, thus dispensing
with the present mode of driving by bands.

by the said James Wood Baker in the Great Seal Patent Office on
the 21st May 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
WOOD BAKER, of Bury, in the County of Lancaster, Cotton Spinner, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of December, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said James Wood Baker, Her special license, that I, the said James
Wood Baker, my executors, administrators, and assigns, or such others as
I, the said James Wood Baker, my executors, administrators, and assigns,
should at any time. agree with, and no others, from time to time 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 SPINNING COTTON AND OTHER
and
FIBROUS MATERIALS," upon the condition (amongst others) that I, the said
James Wood Baker, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what manner
the same was to be 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 I, the said James Wood Baker, do hereby
declare the nature of my 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) :-
:-
This Invention relates to hand and self-acting mules, and consists in
giving a positive motion to the tin roller which drives the spindles by
means of toothed gearing. The rim shaft of the mule is connected by
toothed gearing or otherwise. to an elongated toothed spur wheel of
rather greater length than the draw of the carriage,. so that as the
carriage moves backwards and forwards, a spur wheel in the carriage remains
constantly in gear with the said elongated toothed spur wheel. The spur
wheel in the carriage is connected by suitable gearing to the tin roller shaft,

page_text: and thereby drives the spindles by positive gearing instead of the present
mode of driving by bands.
This Invention will be clearly understood by referring to the figures and
letters on the accompanying Sheet of Drawings, in which Fig. 1 is a longi-
tudinal elevation, and Fig. 2 a transverse section of part of the headstock
and carriage of a self-acting mule to which my improvements are applied.
a represents the framework of the headstock; b the rim shaft; c part of
the carriage; d part of the tin roller; and e the shaft to which it is
attached. The shaft forming part of or fixed to the elongated toothed
spur wheel k revolves, in the bearings f, g, h; the spur wheel k is rather
larger than the draw of the carriage. To the back end of the shaft i, I
fix the spur wheel 7 gearing by means of the intermediate or carrier spur
wheel m into the spur wheel n, fixed to the rim shaft 6, so that when the rim
shaft revolves the spur wheel k revolves also. On the square or central
part of the carriage there is a shaft, having fixed to it the bevil wheel o
and the spur wheel p. The bevil wheel o gears into the bevil wheel q,
fixed to the spur wheel 8, working on a stud and gearing into the spur
wheel t, fixed to the shaft e of the tin roller d. The spur wheel p gears
into the elongated toothed spur wheel k, and thus completes the communi-
cation between the rim shaft 6 and the tin roller d, so that when the rim
shaft revolves the tin roller revolves at a regular speed, proportionate to
the diameters of the toothed wheels by which it is driven, whereas when
the tin roller is driven by bands, as now customary, the motion is irregular and
uncertain.
In order to prevent the injurious effects of the sudden stopping and starting
of the rim shaft, I connect the wheel to the shaft i by friction, as shewn
in section in Fig 3; the wheel is loose on the shaft, and fits between two
discs, one of which is keyed to the shaft, and the other is tightened up
against it by lock nuts, or any other friction apparatus may be employed
for the purpose. Or I place the friction apparatus on any of the shafts or
wheels between the rim shaft and the tin roller. The same object might also
be accomplished by driving the shaft i from the rim shaft 6 by a strap and
pulleys.
Having thus stated the nature of my Invention, and described a convenient
arrangement of parts for carrying the same into operation, I wish it to be
understood that I do not limit myself to the particular arrangements of
parts for communicating motion from the rim shaft to the elongated toothed
spur wheel marked k, nor from that wheel to the tin roller shaft, as the same
may be varied or modified; but I claim the combination of parts employed, as

page_text: herein described, forming a new method of giving motion to the tin roller and
also the use of the elongated toothed spur wheel k, when employed in the
manner and for the purpose described.
In witness whereof, I, the said James Wood Baker have hereunto set my
hand and seal, this Eighteenth day of May, in the year of our Lord
One thousand eight hundred and sixty-three.
Signed, sealed, and delivered by the
within-named James Wood Baker,
in the presence of

JAMES WOOD BAKER. (L.S.)
