Elce, Machine Maker, both of Manchester, in. the County of
Lancaster, for the Invention of "IMPROVEMENTS IN MACHINERY FOR
Scaled the 30th December 1873, and dated the 2nd July 1873.
PROVISIONAL SPECIFICATION left by the said Frederick Wilkinson
and John Elce at the Office of the Commissioners of Patents, with
their Petition, on the 2nd July 1873.
We, FREDERICK WILKINSON, Yarn Agent, and JOHN ELCE, Machine
Maker, both of Manchester, in the County of Lancaster, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN MACHINERY
FOR SPINNING AND DOUBLING COTTON AND OTHER FIBROUS MATERIALS," to be as
follows:-
Our Invention consists, firstly, in a method of driving the spindles of
machines on the throstle principle. For this purpose we apply to each
spindle (or with a variation hereafter to be mentioned) arms or vanes,

page_text: the whole series. As the bearings of the spindles will be kept wet by the
water employed to drive them, no further lubricating material may be
necessary, but when pumped water is used, soap or other such material
may be added thereto, or in place of water oil may be employed for the
int
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Frederick Wilkinson and John Elce in the Great
Seal Patent Office on the 2nd January 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, FREDERICK
WILKINSON, Yarn Agent, and JOHN ELCE, Machine Maker, both of
Manchester, in the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Second day of July, in the year
of our Lord One thousand eight hundred and seventy-three, in the thirty-
seventh year of the reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Frederick Wilkinson and John Elce,
Her special licence that we, the said Frederick Wilkinson and John Elce,
our executors, administrators, and assigns, or such others as we, the
said Frederick. Wilkinson and John Elce, 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 FOR
SPINNING AND DOUBLING COTTON AND OTHER FIBROUS MATERIALS," upon the
condition, amongst others, that we, the said Frederick Wilkinson and,
John Elce, by an instrument in writing under our hands and seals. (or)
under the hand and seal of one of us) should particularly describe and:
ascertain the nature of our 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 Frederick Wilkinson, do hereby,
declare the nature of our said Invention, and in what manner the

page_text: Having thus described the construction of a spindle according to our
Invention, we will proceed to shew its application.
Fig. 2 is a partial cross section of a throstle, one side thereof being
provided with flyers, and the other with rings and travellers. At d is
the footstep for the spindle a formed in a rail e, which has sides ƒ con-
stituting a box, within which the wheel turbine c is situate. Cast with
the rail is a pipe 9, a return part of which crosses the machine, and
there joins another longitudinal pipe g for the other set of spindles, and
at the supply pipe proceeding from the accumulator or other source of
fluid pressure. The pipes g, g, are provided along their length with
apertures leading to the interior of jets l, which are screwed on to the
pipes 9, 9, and are thereby capable of adjustment horizontally, and of
being adjusted upward or downward by suitable packings. At m is a
cover, through which the spindles pass at n, a second cover, but the
spindles run freely through the apertures of both without touching them.
At op is the ordinary arrangement of tin drums, when two are used, but
one only may be employed if desired, and the banding passes around
the wharves 6 in the usual manner, but for the purposes of our In-
vention neither of the drums is driven by the motive power.
Water at a determined pressure being caused to pass into the pipe i
enters by means of the passage h the pipes 9, 9, and issuing through
the jets impinges upon the cup-formed vanes c, and cause sthe
spindles to revolve at a velocity due to the pressure employed, and
the spindles communicate motion to the tin drums by means of the
wharves b, and the rollers become driven in the ordinary manner; but it
will be observed that in one respect the usual operation is reversed,
for according to our Invention the spindles are the drivers, and by
these means the spindle and rollers govern each other for the proper
relative speed.
It has been stated that the speed of the spindles may be varied by
the pressure of the fluid, but a maximum pressure having been adopted
a variation thereof may be obtained by a throttle valve adapted to any
convenient part of the pipe which conveys the fluid. The bottom of the
rail f is provided with apertures q, through which the fluid passes after
it has acted on the turbines, and from thence away by a channel to any
convenient situation, from which it may be returned to the accumulator
or other source of pressure.

page_text: Figs. 3 and 4 represent detached views on an enlarged scale with
similar letters of reference to those above mentioned marked thereon.
In Fig. 4 the jet piece is shewn in section, and at i is a disc of wire
gauze placed between the aperture and the jet piece for the purpose
of preventing solid matter from stopping up the orifice. At the back of
the jet piece is a plug 8, which may be removed to clear out the jets.
We have above stated that the tin drums are driven by the spindles,
but according to our Invention the said drums may be dispensed with
and the drawing rollers driven separately by engine motive power acting
in the usual manner upon the shaft of one of the said drums, but as a
better method, when tin drums as aforesaid are not used, became more
regular in speed than ordinary engine power, we adapt a separate turbine
to the machine to drive the rollers. This may be done by coupling it
to a shaft, upon which a tin drum if used would have been mounted,
and there will therefore be the usual train of wheels by which the speed
of the turbine may be adapted to drive the rollers their proper number
of revolutions, but by placing a throttle valve in the supply pipe and
working as we have described in reference to the spindles at a fixed
initial pressure an adjustment of the said valve will serve to bring the
rollers to their proper speed.
It will however be evident that the train of wheels as now employed
may
be dispensed with or modified, the said throttle valve answering to
the change wheel in common use. As however turbines under the most
favourable conditions usually run at a higher speed than is required for
the rollers some gearing may be necessary.
Having thus described and ascertained the nature of our said Inven-
tion, and the manner in which the same is to be performed, I desire it.
to be understood that we claim as secured to us under the above in part
recited Letters Patent, and for the purposes above set forth,―
Firstly. Driving the spindles of machines of the throstle character by
means of jets or streams of water or other fluid acting against arms or
vanes carried by the said spindles.
Secondly. Causing the spindles so driven to actuate the tin drum or
drums used for driving the rollers.

page_text: Thirdly. Driving the rollers separately from the spindles by means of
a turbine or other ordinary motive power.
In witness whereof, I, the said Frederick Wilkinson, have here-
unto set my hand and seal, this First day of January, in the
year of our Lord One thousand eight hundred and seventy-four.
