IMPROVE- MENTS IN SELF-ACTING MULES
Year: 1874

page_text: LETTERS PATENT to John Henry Smith, of Morley, in the County of
York, Overlooker, and Oliver Heywood Hartley, of Ardsley, near-
Wakefield, in the County aforesaid, for the Invention of "IMPROVE-
MENTS IN SELF-ACTING MULES."
PROVISIONAL SPECIFICATION left by the said John Henry Smith and
Oliver Heywood Hartley at the Office of the Commissioners of
Patents, with their Petition, on the 14th January 1874.
We, JOHN HENRY SMITH, of Morley, in the County of York, Over-
looker, and OLIVER HEYWOOD HARTLEY, of Ardsley, near Wakefield,
in the County aforesaid, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN SELF-ACTING MULES," to be as follows:-
This Invention relates to machinery or mules for spinning of that class
in which an increased speed is imparted to the spindles when the carriage
is "run out."

page_text: carriage and of the rotation of the spindles at any point of the outward
traverse or advance of the carriage.
To the arm or link of the ordinary strap fork lever we connect a rod,
on one end of which is a spiral spring. On the said rod is a stop or
catch piece, which is caught by an adjustable finger attached to the
carriage, and the speed of the carriage and spindles will be increased by
a change of driving power so set in motion. On the return of the
carriage a second stop piece will be operated, drawing the rod and spring
back to their original position, and allowing the first stop piece to engage
again with its catch, and the.mule is reduced in speed.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Henry Smith and Oliver Heywood Hartley
in the Great Seal Patent Office on the 14th July 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
HENRY SMITH, of Morley, in the County of York, Overlooker, and
OLIVER HEYWOOD HARTLEY, of Ardsley, near Wakefield, in the County
aforesaid, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of January, in the
year of our Lord One thousand eight hundred and seventy-four, in
the thirty-seventh year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto us, the said John Henry Smith and
Oliver Heywood Hartley, Her special licence that we, the said John
Henry Smith and Oliver Heywood Hartley, our executors, administrators,
and assigns, or such others as we, the said John Henry Smith and
Oliver Heywood Hartley, 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 SELF-ACTING MULES," upon
the condition (amongst others) that we, the said John Henry Smith and
Oliver Heywood Hartley, our executors or administrators, by an
instrument in writing under our, or their, or one of their hands and
+

page_text: 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.
NOW KNOW YE, that we, the said John Henry Smith and Oliver
Heywood Hartley, do hereby declare. the nature of our 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 relates to machinery or mules for spinning of that class
in which an increased speed is imparted to the spindles when the carriage
is "run out."
The object of this Invention is that by the application of self-acting
mechanism to increase, alter, or vary the speed of the movement of the
carriage and of the rotation of the spindles at any point of the outward
traverse or advance of the carriage.
To the arm or link of the ordinary strap fork lever we connect a rod,
on one end of which is a spiral spring. On the said rod is a stop or
catch piece, which is caught by an adjustable finger attached to the
carriage, and the speed of the carriage and spindles will be increased by
a change of driving power so set in motion. On the return of the
carriage a second stop piece will be operated, drawing the rod and spring
back to their original position, and allowing the first stop piece to engage
again with its catch, and the mule is reduced in speed.
Such being the nature and object of this our said Invention, we will
now proceed to describe the same in detail, and in order that tho
Invention may be fully understood we have hereunto annexed a Sheet
of Drawings, illustrating the construction and arrangement of the appa-
mtus omnlovod

page_text: piece, which is caught by the finger E attached to the carriage, so moving
back the stop piece D, turning the strap fork rod D', and transferring the
strap from the pulley F to the pulley G, and giving slower speed.
Meanwhile the second stop piece H (fixed to and moved by the rod B)
will have been drawn in the direction of the arrow to the end of the
hinged catch J, against which it rests (as shewn by dotted lines). On
the return traverse of the carriage Ę the end of the hinged catch J will
be depressed, so raising the notched end of the lever J out of the notch
in the piece H, whereon the spiral spring will expand again, drawing
back the shaft B to its original position, transferring the strap and again
giving the fast speed. K, K, are slot holes in which the fulcrum of the
lever J can be adjusted, so that by changing the position of the said
lever J and of the stop piece H the change of strap from one pulley to
another can be made at any part of the traverse of the carriage; L is a
collar on the rod B, for the purpose of preventing the spring C moving
the strap fork further than requisite.
Having thus fully described the nature and particulars of this our
Invention, we would have it understood that we claim as our Invention,
the apparatus shewn in the Drawings (or any modification thereof), as
and for the purpose herein fully described.
In witness whereof, we, the said John Henry Smith and Oliver
Heywood Hartley, have hereunto set our hands and seals, this
Eleventh day of July, in the year of our Lord One thousand eight
hundred and seventy-four.
Witness,
