AN APPARATUS FOR GIVING A NEW MOTION TO MULES AND BILLIES
Year: 1825

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HIRST, of Leeds, in the County of York, Gentleman, send greeting.
WHEREAS His present most Excellent Majesty King George the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing
date at Westminster, the Sixteenth day of July, in the sixth year of His reign,
did, for Himself, His heirs and successors, give and grant unto me, the said
William Hirst, and also to Joseph Carter, of Leeds aforesaid, Cotton Spinner,
His especial licence, that we, the said William Hirst and Joseph Carter, our
exors, adiñiors, and assigns, or such others as we, the said William Hirst and
Joseph Carter, our exors, admors, or assigns, should at any time agree with,
and no others, from time to time and at all times during the term of years
therein expressed, should and lawfully might make, use, exercise, and vend,
within England, Wales, and the Town of Berwick-upon-Tweed, our Invention
of "AN APPARATUS FOR GIVING A NEW MOTION TO MULES AND BILLIES;" in
which said Letters Patent is contained a proviso obliging us, or one of us, the
said William Hirst and Joseph Carter, by an instrument in writing under
our, or one of our, hands and seals, particularly to describe and ascertain the
nature of our said Invention, and in what manner the same is to be performed,
and to cause the same to be enrolled in His said Majesty's High Court of
Chancery within six calendar months next and immediately after the date
of the said recited Letters Patent, as in and by the same, reference being
thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
William Hirst, do hereby declare the nature of our said Invention to consist
in causing the carriage of mules and billies to stop when the length of

page_text: stubbing is taken, and remain stationary for a short time till the operation of
untwisting the slubbing is completed, and then to move on again to its usual
destination for the purpose of drawing and twisting the slubbing. Now, it is
evident that to obtain this end two things are necessary, first, to stop the
carriage, and, secondly, to set it in motion again. And in further com-
pliance with the said proviso, I, the said William Hirst, do hereby therefore
describe the manner in which our said Invention is to be performed by the
following description thereof, reference being had to the Drawings annexed,
and the Figures marked thereon, that is to say:-
DESCRIPTION OF THE DRAWINGS.
The Drawing marked A represents a side clevation of so much of our said
Invention as relates to the stopping of the carriage when the length of
slubbing is taken; and I have only shown such parts of an ordinary mule as
were necessary. to explain this part of our Invention, which consists solely in
the fixing of the spring marked S, and colored purple, in the situation here
shown, and doing away with the rod which leads from the sneck to the lever
at the back of the machine in ordinary mules. It will be seen that this spring
(which is made of strong wire of similar shape and size to the ordinary spiral
spring) is fixed at one end to the lower part of the scroll.frame.at a, and at the
other end e to the ordinary crank movement c, which moves the line shaft in
and out of gear. In the position shown in the Drawing, the spring is at full
stretch, and the lower end a of the scroll frame being thereby drawn towards e,
the wheel W is kept in gear in this position; the line shaft is also supposed to
be in gear and the carriage regularly put up. If the carriage be now started
in the ordinary way, the crank C will, on the carriage arriving at a proper
distance, throw the line shaft out of gear. This motion of the crank will
slacken the spring S, and the wheel W will instantly fall out of gear, and
thereby the carriage will be caused to stop till the wheel W is again thrown
into gear. The operation of throwing the wheel W into gear again is per-
formed by means the principal parts of which are at the opposite side of the
machine to that here represented, and more particularly shown in the Drawing.
marked B, which I will now proceed to describe.
.
This Drawing B represents a perspective view of that part of our said
Invention which relates to the setting of the carriage in motion again after it
bas been stopped, in manner aforesaid. is the ordinary sneck, and it is well
known that the effect of taking the sneck off the point of the weighted lever L
is to put the scroll into gear. To effect this, therefore, before the carriage
arrives at the end of the draw, the parts coloured purple in this Drawing are
°

page_text: added to the old machine; and it will be seen by a reference to the Drawing,
that if the rod X be lifted up, the necessary effect of the crank Z, the
connecting rod Y, and the lever V, will be to push the sneck off the point
of the lever L, which immediately throws the scroll into gear again, and the
carriage moves forward again to the end of the draw in the usual way of
putting the sneck on the lever again at the end of its journey, in the ordinary
manner. In order to determine when to raise the rod X, and for the purpose
of raising it, the additional finger or catch t is fixed upon the twist shaft, and
so adjusted by means of a screw in the ordinary way that it does not come in
contact with the shaft X to raise it until the carriage shall have stopped a
sufficient length of time to complete the untwisting of the slubbing, the object
of our Invention being to complete the untwisting of the slubbing before it is
drawn for spinning.
Having now described the two things required as aforesaid, I will describe
the relative situation of the new parts in the machine, which constitute our said
apparatus, and their general effect, by reference to the Drawing marked C.
This Drawing represents a side elevation of the whole machine generally.
Now, when the carriage arrives at the point shewn by the dotted lines, the
length of the slubbing is taken, and at the same instant the spring S is
slackened and the scroll thrown out of gear, which, of course, stops the
carriage, but the twist bar continues to revolve, and when the extra finger t
arrives at the catch or lip, at the top of the rod X, it lifts up the rod X, and
this, as has before been explained, throws the scroll again into gear and thus
puts the carriage into motion again. It should here be observed, that the
parts which constitute what we call our apparatus, are colored of a purple
color in all the Drawings. And whereas we claim nothing but the parts
coloured purple as our said Invention; but such parts being to the best of our
knowledge and belief entirely new, and never before used within that part of
His said Majesty's United Kingdom of Great Britain and Ireland called
England, His said Dominion of Wales, or Town of Berwick-upon-Tweed, I
do hereby declare this to be our Specification of our said Invention, and that I
do verily believe this our said Specification doth comply in all respects fully, and
without reserve or disguise, with the proviso in our said herein-before in part
recited Letters Patent contained; wherefore we do hereby claim to maintain
exclusive right and privilege to our said Invention.
In witness whereof, I, the said William Hirst, have hereunto set my hand
and seal, this Twelfth day of January, in the year of our Lord One
thousand eight hundred and twenty-six.
W (L.S.) HIRST.

page_text: AND BE IT REMEMBERED, that on the Twelfth day of January, in the
year of our Lord 1826, the aforesaid William Hirst came before our said
Lord the King in His Chancery, and acknowledged the Specification afore-
said, and all and every thing therein contained and specified, in form above
written. And also the Specification aforesaid was stamped according to the
tenor of the Statute made for that purpose.
