Year: 1868

page_text: LETTERS PATENT to Joe Booth Whiteley, of the Prospect Iron
Works, Lockwood, near Huddersfield, in the County of York, for
the Invention of "IMPROVEMENTS IN MACHINERY FOR STRETCHING,
DRYING, AND PRODUCING THE ELASTIC FINISH' ON WOVEN FABRICS."
PROVISIONAL SPECIFICATION left by the said Joe Booth Whiteley
at the Office of the Commissioners of Patents, with his Petition,
on the 20th May 1868.
I, JOE BOOTH WHITELEY, of the Prospect Iron Works, Lockwood,
near Huddersfield, in the County of York, do hereby declare the.
nature of the said Invention for "IMPROVEMENTS IN MACHINERY FOR
STRETCHING, DRYING, AND PRODUCING THE ELASTIC FINISH' ON WOVEN
FABRICS," to be as follows:-
This Invention relates to machinery for which Letters Patent were
granted to the late William Whiteley of this Place, dated respectively
the 10th day of February 1854, No. 332, and the 13th day of

page_text: February 1864, No. 382; also to further improvements thereon for
which Provisional Protection has been granted to me, the said J. B.
Whiteley, dated the 27th day of February, 1868, No. 661, this latter
having the object of producing what is technically known as the elastic
finish, and therein proposed to be effected by alternate intermittent
movements of the endless chains on which the edges of the fabrics to be
treated are hooked, and by which the said fabric is carried or conducted
through the machine. Now since the grant of this later protection
I have found that instead of one chain being moved forward and then
remain stationary while the other is moved forward alternately, as set
forth in the said Provisional Specification, a better effect is produced on
the fabrics under operation for the production of this elastic finish by
keeping both chains in motion, each having a forward and backward
motion imparted in such manner that while one is advancing the other
is receding in like manner, so that the action on each list or edge of
the fabric is equal in effect, and a progressive motion is also given to the
chains to carry the fabric through the machine. This combined move-
ment may be obtained by the employment of a driving shaft on which
are two spur wheels running loose and gearing with the spur wheels
attached to the chain wheels. To each of these wheels is affixed a bevil
wheel which face each other. A bevil pinion gears in each, which are
mounted upon two short crank shafts placed at right angles to and
carried by the first-named shaft. A rod connects these two crank
shafts with another rod operated by an excentric or crank which gives
reciprocatory motion in the direction of the axis of the first-named shaft.
The reciprocatory action of the small cranks and pinions give oscillatory
or vibratory motion to the wheels which carry the chains, and the
rotary motion of the driving shaft gives forward motion to the said
chains. Also, I so arrange these shafts and the gearing thereof
respectively as to apply change gear, and thereby regulate the relative
speeds of the progressive and the oscillatory or vibratory motions as
'found desirable or so as to produce either motion independently of or
without the other motion if required, or other mechanical equivalent
means may be employed to obtain this combined motion of the chains.

November 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOE
BOOTH WHITELEY, of the Prospect Iron Works, Lockwood, near
Huddersfield, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twentieth day of May, in the year
of our Lord One thousand eight hundred and sixty-eight, in the thirty-
first year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Joe Booth Whiteley, Her special licence
that I, the said Joe Booth Whiteley, my executors, administrators,
and assigns, or such others as I, the said Joe Booth Whiteley, 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
"IMPROVEMENTS IN MACHINERY FOR STRETCHING, DRYING, AND PRODUCING THE
ELASTIC FINISH' он WOVEN FABRICS," upon the condition (amongst
others), that I, the said Joe Booth Whiteley, my executors
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.
or
NOW KNOW YE, that I, the said Joe Booth Whiteley, 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 and accompanying Sheet of Drawings
(that is to say) :-
:-
This Invention relates to machinery for which Letters Patent were
granted to the late William Whiteley of this Place, dated respectively
the 10th day of February 1854, No. 332, and the 13th day of

page_text: February 1864, No. 382, also to further improvements thereon, for
which Provisional Protection has been granted to me the said J. B.
Whiteley, dated the 27th day of February 1868, No. 661, this latter
having the object of producing what is technically known as the
"elastic finish" and therein proposed to be effected by alternate
intermittent movements of the endless chains on which the edges of the
fabrics to be treated are hooked, and by which the said fabric is carried
or conducted through the machines. Now since the grant of this latter
protection I have found that instead of one chain being moved forward
and then remain stationary while the other is moved forward alternately
as set forth in the said Provisional Specification, a better effect is
produced on the fabrics under operation for the production of this
elastic finish by keeping both chains in motion, each having a forward
and backward motion imparted in such manner that while one is
advancing the other is receding in like manner so that the action upon
each list or edge of the fabric is equal in effect, and a progressive motion
is also given to the chains to carry the fabric through the machine.
This combined movement of the chains may be obtained by various
mechanical means or arrangements of apparatus, but in order that this
Invention may be fully understood I herein give reference to an
accompanying Sheet of Drawings of such portions of a stretching and
drying machine as will enable me to shew the application of the best
means I am acquainted with for carrying the said Invention into
practice, yet other mechanical equivalent means may be employed to
obtain this combined motion of the chains,
Fig. 1 is an end elevation; Fig. 2, part of the side elevation; and
Fig. 3 is a plan thereof.
A and A¹ are the two endless chains, having hooks for holding the
fabric thereon in the usual manner. The chains are carried on pullies
or chain wheels B and B' which run loose on slide bosses carried on
the shafts C and C', which also carry the ordinary rollers D and D',
which it may be observed are of the telescopic kind so as to render the
machine adaptable to the various widths of fabrics required to be
operated upon or passed through this machine to be stretched and dryed.
E and E are spur wheels fixed to the chain wheels or pullies through
which motion is communicated to the chains, as herein-after described

page_text: spur
F is a spur wheel, fixed to which is a bevil wheel which recieves motion
this
from the ordinary driving shaft of the machine;
wheel gears
with the wheels F and F fixed on the two shafts C and C', by which
motion is given to the rollers D and D'. On the shaft C is also fixed
a wheel G which gears into a wheel G' fixed on one axis of a rotary
frame H (shewn in detail at Fig. 4). On the other axis of this frame
is fixed a wheel I which gears (by a stud wheel I') with a wheel I² fixed
on a shaft J. On this shaft is fixed a wheel J' in gear with a combined
spur and bevil rim wheel J' supported and capable of rotating on a boss
or circular flanged plate H' which is carried on four rods h forming a
portion of the frame H. The bevil part of the wheel J gears with a
bevil wheel Js mounted on a shaft 3 which is supported in bearings J³
and Je cast or fixed on the boss or plate H'. On this shaft is fixed an
eccentric K to which is attached a rod K' connected to a crank shaft L,
supported in bearings L' and L' fixed to the boss of another flanged
plate H. On this crank shaft is a bevil wheel M gearing with another
combined bevil and spur rim wheel M which is supported and capable
of rotating on the boss or flanged plate H2, which is like H' carried on
the four rods. This bevil wheel M also gears with another combined
bevil and spur rim wheel M which is supported and capable of rotating
on another boss or flanged plate H³. The spur part of the wheel M'
gears with a spur wheel N loose on a shaft N', on which are also fixed
two other wheels N2 and N. The wheel N gears with another wheel N*
fixed on a shaft N on which is also another wheel N in gear with the
wheel E fixed to the chain wheel B. The wheel N is in gear with and
recieves motion from the wheel M' and the wheel N³ is in gear with a
wheel P fixed on a shaft P¹ on which is also fixed a wheel P* in gear
with the wheel E' fixed to the chain wheel B¹. It will be observed
that continuous rotary motion is given to the frame H and also through
the train of gearing to the eccentric which produces an oscillatory or a
rocking motion of the crank shaft, which motion being communicated
by the bevil wheel M to the rim wheels M' and M2 they will be
constantly oscillating or moving backward and forward in contrary
directions to each other, thus communicating their motions respectively
to the two chains, so that a combined progressive as well as an
oscillatory or vibratory motion is given to the chains which carry the
fabrics through the machine, and consequently producing or effecting
the elastic finish thercon, and it will be readily seen that by a change
of some of the gear wheels the relative speeds may be varied, or by

page_text: taking away the stud wheel I' the progressive motion may be used
without the oscillatory or vibratory motion of the chains.
Having thus described the nature of my said Invention, and shewn
by the accompany Sheet of Drawings the manner in which the same
is or may be performed or carried into practical operation, I would have
it understood that I do not confine myself to the precise details shewn
and described, as modifications may be made therein, but what I claim
as my Invention is, the method and means of producing a combined
progressive and oscillatory or vibratory motion of the chains of machinery
for stretching and drying fabrics, substantially as shewn and described.
In witness whereof, I, the said Joe Booth Whiteley, have here-
unto set my hand and seal, this Nineteenth day of November,
in the year of our Lord One thousand eight hundred and sixty-
eight
JOE BOOTH WHITELEY. (L.S.)
