Year: 1866

page_text: LETTERS PATENT to James Wood Baker, of No. 28; Moorgate Street, in
the City of London, in the County of Middlesex, Gentleman, for the
Invention of IMPROVEMENTS IN MACHINERY OR APPARATUS FOR SPINNING
COTTON AND OTHER FIBROUS MATERIALS."
Sealed the 5th April 1867, and dated the 9th October 1866.
PROVISIONAL SPECIFICATION left by the said James Wood Baker at
the Office of the Commissioners of Patents, with his Petition, on the
9th October 1866.
I, JAMES WOOD BAKER, of No. 28, Moorgate Street, in the City of London,
in the County of Middlesex, Gentleman, 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 consists of certain improvements upon the machinery for
driving the spindles of self-acting or hand mules for which former Leiters
Patent were granted to me on the 18th day of December 1862, No. 3336.
In the Specification of the said Letters Patent I described how the spindles
were driven by means of an elongated toothed spur wheel, the length of which -
was rather more than the length of the stretch; this wheel when made is in

page_text: one length or part, and is very difficult and uncertain to cast owing to the
extreme depth of the tooth, and is obliged to be much stronger and heavier
than otherwise necessary in consequence, thereby increasing the cost, limiting
the speed at which it can be driven, and increasing the power for driving the
same. Now my present Invention consists in making this elongated wheel of
two or more lengths or parts, and supporting the axle thereof at about the
centre of its length, or at any intermediate part by a bearing or bearings, and
which bearing or bearings will prevent the vibration of the wheel, and admit
of a much higher velocity than was hitherto practicable; the cost of production
and the weight of the elongated wheel being also very considerably reduced.
When the elongated wheel is made in two or more equal lengths there must
be sufficient space left between the parts for the bracket of the bearing or
bearings, consequently the intermediate wheel for communicating the motion
of the elongated wheel to the tin drum must be rather broader than before, so
that in traversing along with the carriage it may be in gear with the various
lengths of the elongated wheel. at the same time when passing over the space
or spaces between the ends.
Another
part of my Invention consists in communicating motion from the
elongated wheel described in my former Patent above referred to, or the
improved elongated wheel above described, by means of an intermediate wheel
gearing into a spur wheel, on the axle of which is a mitre or bevel wheel
gearing direct into a mitre or bevel wheel on the tin drum shaft, thereby
greatly simplifying the gearing and reducing the cost of production. In order
to prevent the injurious effects of the sudden stopping and starting of the rim
shaft I fix a friction cone to the end of the axle of the elongated spur wheel;
on this friction cone fits a friction box, which is loose on the axle, but held in
contact with the friction cone by a spring. When the mule carriage is near
the end of the draw or stretch the friction box is released or eased from the
friction cone by a lever passing over an adjustable incline acting on a side rod
connected to the lever of the spring above referred to. By this arrangement
the rim shaft is disengaged when required from the elongated wheel, and the
momentum of the spindles and tin roller is allowed to expend itself without
injury to the gearing or parts of the machine. The rim shaft is connected to
the elongated spur wheel by pulleys and strap or by a shaft and spur or bevel
gearing.

by the said James Wood Baker in the Great Seal Patent Office on
the 6th April 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
WOOD BAKEB, of No. 28, Moorgate Street, in the City of London, Gentleman,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of October, in the year of our Lord
One thousand eight hundred and sixty-six, in the thirtieth 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 .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 "IMPROVE-
MENTS IN MACHINERY FOR SPINNING COTTON AND OTHER 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 ascer-
tain 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 tho 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 consists of certain improvements upon the machinery for
driving the spindles of self-acting and hand mules for which former Letters
Patent were granted to me on the Thirteenth day of December, One thou-
sand eight hundred and sixty-two, No. 8886. In the Specification of the
said Letters Patent I described how the spindles were driven by means of an
elongated toothed spur wheel, the length of which was rather more than the
length of the stretch; this wheel when cast is inconveniently heavy, thereby
increasing the-cost, limiting the speed at which, it can be, driven, and
increasing the power for driving-it..

page_text: Now my present Invention consists in making this elongated wheel of two
or more parts, and supporting the axle thereof at about the centre or at any
intermediate part of its length by a bearing or bearings, which bearing or
bearings will prevent the vibration of the wheel even when it is driven at a
considerably greater speed than was heretofore practicable; the cost of pro-
duction and the weight are also reduced. When the elongated wheel is made
in two or more parts there must be sufficient space left between the ends for
the bracket of the bearing or bearings, consequently the intermediate wheel
for communicating the motion of the elongated wheel to the tin drum must be
rather broader than before, so that in traversing along with the carriage it
may be in gear with both parts of the elongated wheel at the same time when
passing over the space or spaces between the ends.
Another part of my Invention consists in communicating motion from the
elongated wheel described in my former Patent above referred to, or the
improved elongated wheel above described by means of an intermediate wheel
gearing into a spur wheel, on the axle of which is a mitre or bevel wheel
gearing direct into a mitre or bevel wheel on the tin drum shaft, thereby
greatly simplifying the gearing and reducing the cost of production. In order
to prevent the injurious effects of the sudden stopping and starting of the
rim shaft I fix a friction cone to the end of the axle of the elongated spur
wheel; on this friction cone fits a friction box, which is loose on the axle, but
held in contact with the friction cone by a spring. When the carriage is
near the end of its stretch the friction box is released or eased from the
friction cone by a lever passing over an adjustable incline acting on a side rod
connected to the lever of the spring above referred to; by this arrangement'
the rim shaft is disengaged when required from the elongated wheel, and the
momentum of the spindles and tin roller is allowed to expend itself without
injury to the parts of the machine. The rim shaft is connected to the
elongated wheel by pulleys and strap or by a shaft and spur or bevel gearing.
And in order that my Invention may be more fully understood, and readily
carried into operation, I will proceed to describe the accompanying Sheet of
Drawings, reference being had to the figures and letters marked thereon.
Figure 1 is a side elevation of part of the headstock of a self-acting mule
to which my improvements are applied, and Figure 2 is an end view of the
same.
A is the framing of the headstock; B, the rim band shaft; C, the carriage
running on the wheels C¹; D, the drum for driving the spindles V by means of
the band X; these parts of the mule are made in the ordinary manner. K is
the elongated toothed spur wheel, which instead of being made in one piece

page_text: and of a rather greater length than the stretch, as described in the Specifi-
cation of Letters Patent granted to me on the Thirteenth day of December; -
One thousand eight hundred and sixty-two, No. 3886, I now-make-in two
parts, as shewn in Figure 1, or in more than two parts if required. The axle
of the wheel K is supported in the bearings F, G, and H, and in the inter-
mediate bearing E, the bracket of which passes between the inner ends of the
two parts of the wheel K. It is evident that when the wheel K. is composed
of three or more parts two or more intermediate bearings similar to E
may be used. The wheel K drives the intermediate wheel P, which com-
municates motion to the tin drum D, and which is made sufficiently broad
that when traversing along with the carriage it may be in gear with both parts
of the wheel K at the same time when passing over the space between the
ends thereof,
The second part of my Invention consists in communicating the motion of
the elongated wheel to the tin drum D by means of the intermediate wheel P
above referred to gearing into the pinion R fixed on the same shaft as the
mitre wheel S which drives the wheel T fixed to the tin drum shaft.
The last part of my Invention may be described without reference to
Drawings, and it consists in applying a friction cone to the end of the axle of
the elongated wheel K; on this friction cone fits a friction box, which is
loose on the axle, but held in contact with the friction cone by a spring.
When the carriage is near the end of its stretch the friction box is released or
eased from the friction cone by a lever passing over an adjustable incline acting
on a slide rod connected to the lever of the spring above referred to; by
this arrangement the rim shaft is disengaged when required from the
elongated wheel, and the momentum of the spindles and tin roller is allowed
to expend itself without injury to the parts of the machine. The rim shaft B
is connected to the axle of the elongated wheel K by spur wheels, as
shewn in Figure 1, or by pulleys and strap, or by a shaft and bevel gearing.
The advantages resulting from the improvements above described are,
first, dispensing with the rim bands, rim band pulleys, guide pulleys, and the
studs and fixings connected therewith; secondly, giving uniformity of twist
to the yarn, increasing the production of the spindles, and avoiding break
downs, delay, and expense; and, lastly, saving in power and oil, reducing the
wear and tear of the scroll-bands, and increasing the regularity in winding.
Having thus stated the nature of my Invention, and described the manner
of performing the same, I declare that I claim,-
First, making the elongated spur wheel marked K in two or more parts;-
and supporting the axle thereof in-the manner shewn and described.

page_text: Secondly, the improved mode of communicating the motion of the elongated
wheel to the tin drum shaft, as shewn and described.
And, lastly, the application of a friction apparatus between the rim band
shaft and the axle of the elongated spur wheel, as described.
In witness whereof, I, the said James Wood Baker, have hereunto set 5
my hand and seal, this Fourth day of April, One thousand eight
hundred and sixty-seven..
