Year: 1874

page_text: LETTERS PATENT to William Whiteley, of the Firm of William
Whiteley and Sons, of Lockwood, Huddersfield, in the County of
York, Machine Makers, for the Invention of "IMPROVEMENTS IN
MACHINERY FOR ROVING AND SPINNING FIBROUS SUBSTANCES.”
Sealed the 3rd November 1874, and dated the 21st May 1874.
COMPLETE SPECIFICATION filed by the said William Whiteley at
the Office of the Commissioners of Patents, with his Petition and
Declaration, on the 21st May 1874, pursuant to the 9th Section of
the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
WHITELEY, of the Firm of William Whiteley and Sons, of Lockwood,
Huddersfield, in the County of York, Machine Makers, send greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS IN
MACHINERY FOR ROVING AND SPINNING FIBROUS SUBSTANCES," and have peti-
tioned Her Majesty to grant unto me, my executors, administrators,

page_text: and assigns, Her Royal Letters Patent for the same, and have made
solemn Declaration that I am the true and first Inventor thereof.
NOW KNOW YE, that I, the said William Whiteley, do hereby
declare that the following Complete Specification, under my hand and
seal, fully describes and ascertains the nature of the said Invention, and
in what manner the same is to be performed, in and by the following
statement and accompanying Sheets of Drawings (that is to say):—
The object of this Invention is to obtain by means of improved
machinery improved results as regards the operations of roving and
spinning, and also to economize space or room. To effect this object I
adapt the principle of the spinning mule to the spinning frame, com-
bining so to speak the two machines in the manner herein-after described,
that is, I construct a framework something similar to the ordinary
worsted spinning frame, having a series of spindles and flyers, guide
eyes, back or delivery rollers, and a creel board or provision for cops or
condenser bobbins.
I also construct and apply to this frame novel machinery consisting
of travelling carriages or frames to carry rotary tubes provided with
nippers or holding instruments. These carriages are in pairs and travel.
forward and backward betwixt the guide eyes and delivery rollers alter-
nately, that is, while one is advancing the other is retiring. The nippers
seize and hold the rovings or threads at one certain time, and liberate
them at another. The travelling carriages are arranged so that while
the nippers of one carriage will seize on the rovings near to the delivery
rollers the nippers of another carriage will open to liberate the rovings
near to the guide eyes; then the said carriage will run in on the
rovings until meeting the other carriage, the latter liberating its roving,
which will be seized by the nipper of the bottom carriage, the top
carriage returning to the delivery rollers for more roving. The tubes
will be revolving so as to give the twist to the rovings requisite for the
draught of the same. The rotary motion of the tubes during the travel
of the carriages from the delivery rollers to the guide eyes for the purpose
of giving twist to the rovings may be driven by either cord, belt, or other
suitable driving means.
"
"
The operations of the carriages and delivery rollers are to be regulated
in a manner somewhat similar to the ordinary mule so as to put more or

page_text: Ine movement of the carriages may be effected either by screws or by
rack and pinions or other equivalent means.
In order that this Invention may be fully understood I have hereunto
annexed six Sheets of Drawings explanatory of the construction and
working of the apparatus employed by me to effect the desired object.

page_text: these shafts, on the ends of which are the bevel wheels 25, 25, gearing
with the wheels 26, 26, on the screw or worm shafts 27, 27. These, as
shown, have each a variable right and left-handed screw formed thereon,
which screws give a reciprocatory or traversing motion to the carriages or
rails 29, 30, within which the nippers 31 are carried and work, receiving
their rotary motion from the driving bands 32 from the driving pulleys
33, 34. These pulleys work loosely or slide on the shaft 35, and drive
the nippers only on the " going out" or movement of the carriage from
the delivery rollers 35*. A clutch box, the catch 36 of which is operated
by the outer case piece 37 of the carriage coming in contact with the
stop piece 38* puts the clutch in gear, and so drives the pulleys 33 and
band during the "going out" movement of the carriages, and being
thrown out by the stop piece 36* prepartry to the return or "in" move-
ment of the carriage, the shafts 35 carrying the pulleys being driven by
means of the spur wheel 34 on the end of the first driver gearing with
the spur wheels 35** gearing with 36, to which is cast a bevel wheel 37
working on a stud gearing with bevel 37* on the shaft 38. At the end
of shaft 38 are the bevels 39 driving the shaft 35 carrying the said
driving pulleys for giving rotation to the nippers.
The construction and operating of the nipping jaws will be fully
understood by reference to Figs. 7, 8, 9, 10, 11, 12, and 13, aided by the
following description:-A is a hollow spindle or tube having wharle B
formed thereon, through which the required rotation is given by band,
as already described. The upper portion of this spindle or tube is pro-
vided with nipping jaws c, c', forced together by the spiral springs E, E,
thus holding the sliver or "condensing." The carriage and nippers are
now caused by the screws (described) to recede from the delivery rollers,
drawing and twisting the fibre until reaching the stop piece or collar 36º,
whereon the outer case piece 37 of the carriage is forced or moved
upwards and held in that position by the catches 36ª. The beveled
apertures G thereon act on the enclined or beveled ends of the nipping
jaws, forcing them open and releasing the yarn, which will be then
siezed by the similar jaws of the carriage below which traverse by its
screws towards the spindles; meanwhile the first carriage will by the
reverse motion of its screw be carried upwards near to the delivery
rollers 35*, whereon the stop piece 38* will act on the catch 36ª, releaving
the outer casing 37, which will then liberate the jaws of the nippers.

page_text: The spiral springs acting on the jaws as above described cause them to
again seize the yarn, ready to repeat the operation above described. The
carriage 30 in like manner having traversed and twisted the fibre on its
outward movement will release its hold of the yarn and be carried by its
screw up to and receive its next length of roving brought by the upper
carriage 29 and nippers 31.
The delivery rollers have intermittant rotation imparted to them by.
means of the mitre wheels 42, 42, on the diagonal shaft 43, at the end
of which is the worm 44 and worm wheel 45 working on stud. The
worm is thrown in and out of gear with its wheel by means of a peg
wheel 46, a peg on which acts on the pulley 45* attached to the swivel
lever carrying the diagonal shaft 43. The catch 47 serves to hold the
worm in gear until a peg in the peg wheel acts on the pulley 48 of the.
catch, releaving the catch and allowing the worm to fall clear of its
wheel. Cast to the worm wheel 45 are mitre wheels 49 communicating
motion to the vertical shaft 50, on which is a mitre 51 gearing with 52.
To the latter is cast the spur wheel 53 gearing with 54 into 55 on the
spindle of the delivery rollers. The sliver passes from the bobbin 56 to
the delivery rollers 35*, where it is held between them. It is seized by
the nippers 31, which at once begin to rotate, and the carriage 29 is
drawn out by the variable screws 27, thus imparting to the carriage a
like movement to that of the carriage of the ordinary spinning mule
derived from the "scroll," the delivery rollers giving out such supply of
sliver or roving, and during such portion of the traverse of the carriage
and nippers as to allow of the necessary draught or elongation as in the

page_text: such as is above described, and operated in the manner and by the means
substantially as above set forth.
In witness whereof, I, the said William Whiteley, have here-
unto set my hand and seal, this Nineteenth day of May, in the
year of our Lord One thousand eight hundred and seventy-
four.
