page_text: LETTERS PATENT to Aaron Metcalf, of Preston, in the County of
Lancaster, Machinest, and William Gibbons, of the same Place,
Agent, for the Invention of "IMPROVED STRAPPING MOTION IN MULES
FOR SPINNING."
PROVISIONAL SPECIFICATION left by the said Aaron Metcalf and
William Gibbons at the Office of the Commissioners of Patents,
with their Petition, on the 28th June 1870.
We, AARON METCALF, of Preston, in the County of Lancaster,
Machinest, and WILLIAM GIBBONS, of the same Place, Agent, do hereby
declare the nature of the said Invention for "IMPROVED STRAPPING MOTION
IN MULES FOR SPINNING," to be as follows:-
We attach a rod to the top of the quadrant arm by a bracket, which
rod is made to swivel at such bracket, this rod extends to below the
end of quadrant arm.
On the bottom end of screw in the quadrant
arm is fixed a grooved band pully, round which we pass a band, one

page_text: end of which is fixed to one end of a bracket, the other end to the other
end of such bracket; this bracket is fixed near the bottom of the
aforesaid rod. There is another bracket fixed below the quadrant arm
which forms a guide for the end of the rod. To the nut working on the
quadrant arm screw we attach a small bracket or screw for the purpose
of regulating the rod.
We set the
In place of the aforesaid band and pully we can get the same result
by a rack and pinion and friction plates or catch wheel. Or we may
substitute for the nut at present used a nut pinion on the screw worked
by a rack or chain, or a pully nut and band; if we work it by a pinion 1
nut we attach a friction to such nut or a catch wheel.

bend the rod if required to suit the shape of the cop bottom. Its
purpose is to work the nut as required up the quadrant arm during
the building of cop bottom. This has formerly been done by by hand, 1

TO ALL TO WHOM THESE PRESENTS SHALL COME, we, AARON
METCALF, of Preston, in the County of Lancaster, Machinest, and
WILLIAM GIBBONS, of the same Place, Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-eighth day of June, in the year
of our Lord One thousand eight hundred and seventy, in the thirty-
third year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Aaron Metcalf. and William Gibbons,
Her special licence that we, the said Aaron Metcalf and William
Gibbons, our executors, administrators, and assigns, or such others as
we, the said Aaron Metcalf and William Gibbons, our executors, ad-
ministrators, 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 "IMPROVED STRAPPING MOTION

page_text: IN MULES FOR SPINNING," upon the condition (amongst others) that we, the
said Aaron Metcalf and William Gibbons, our executors or adminis-
trators, by an instrument in writing under our, 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.
NOW KNOW YE, that we, the said Aaron Metcalf and William
Gibbons, 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 :-
Our Invention relates to what is usually termed the strapping motion
in spinning mules. It is a special action on the screw of quadrant
arm usually performed by the minder or by very imperfect mechanical
means for building the cop bottom.
Our object in this Invention is to make a perfect cop bottom without
the aid of the minder, preventing snarls, cut yarn, and backlashed cop
bottoms so common and mostly caused by irregular strapping.
Hereunto we annex a Sheet of Drawings in which we fully show one
way of applying our Invention (by preference), but we are compelled to
vary in details to suit the various makes of mules.
Fig. 1 shows the end of mule head, stock, and carriage with one way
of applying our Invention. "A" is the mule head stock fram; 66 B,"
the quadrant arm; "C," a pendulum rod working on a pin at "D,"
at the bottom or near the bottom of such is a quadrant rack "E"
acting upon a pinion "F," such pinion is connected to bevel or mître
wheel working into one fixed on the end of the screw "G" in the
quadrant arm. There is likewise a catch wheel to prevent the turn of
screw when the quadrant rack "E" returns. On the nut "H" of
quadrant screw is a set screw or stop to traverse with the said nut
to act as a stop for the pendulum. "I" is the mule carriage; "0, 0,”
the ordinary faller rods. On the counter faller rod we secure a sickle-
shaped bow "P" attached at "Q" to a pendulum bar "R," in this we
provide an oblong slot hole "S" for regulating the fixing of a catch
finger which falls naturally into catch teeth in the concave or other
shaped catch quadrant "T" which is formed of a bracket shape working

page_text: on pin. Affixed to the carriage of mule "U" is a bracket fixed on the
floor to which is fulcrumed a ballanced lever "V" of "L" or other
shape. When the carriage is going in the pendulum bar "R" in con-
tact with sickle-shaped bow "P" strikes the lever "V" which sets
such pendulum bar at the required position in the concave rack, which
is held in that position until the carriage has returned out, when such
bar strikes the rod "C" gives motion outward to the quadrant rack "E"
attached thereto, thus turning the pinion wheel "F" in connection with
screw "G," thus at the traverse of the mule carriage inwards the nut
ís raised nearer the top of the quadrant arm "B" thus keeping the yarn
at a proper tension without the assistance of the minder.
Fig. 2 is a plan of the same in which the several parts are marked by
similar letters of reference. We likewise effect the same by substituting
for pinion and friction plate or catch a groved pulley, and in place of
rack "E" at the bottom of pendulum a quadrant-shaped bar or strap
or band to work in grove pulley. We likewise effect the same by
fixing on the quadrant nut a pinion or pulley, friction or catch wheel,
and on the before-mentioned rod or pendulum "C" we place a rack or
band or radius bar which is worked by the before-mentioned pendulum,
being connected with lever on the floor and by action of quadrant of
mule, thereby causing rack, rail, or band, to move backwards and
forwards causeing the nut to move upwards as before mentioned until
the finishing of the cop bottom. The speed of the said nut is determined
by the action of rod connected to the counterfaller acting on lever
fixed on floor.
We obtain the same results by the following means in place of
pendulum rod "C":-We fix a pulley on the top and bottom of quadrant
arm, and over such pulleys we place a chain, strap, or band; on the nut
of quadrant we fix a bracket to which we attach the chain, strap, or
band, or allow such chain, strap, or band to run loose, but coming in
contact with such nut when required; we fix a rod with collar or
bracket near the end; at the other end of such rod we fix a rack to
work in pinion "F" connected with screw as before mentioned and
worked backward and forward by the apparatus on counterfaller and
carriage.
Having described our Invention and several ways we have worked
it, we wish it to be understood that we do not confine or limit ourselves
to the precise details here described and illustrated, as the same may be

page_text: varied without departing from the principal of our Invention; but what
we claim as our Invention is,―
First. The pendulum rod "C," the quadrant rack, and connecting
motion, as herein-before described.
Second. The sickle-shaped bow "P," and pendulum bar "R" with
its connection with the counterfaller only, and with concave or other
shaped catch quadrant "T" and bracket with lever on floor, as herein-
before described.
Third. The general arrangement and parts in connection with and
for the purposes herein-before described and illustrated.
In witness whereof, we, the said Aaron Metcalf and William
Gibbons, have hereunto set our hands and seals, this Twenty-
third day of December, in the year of our Lord One thousand
cight hundred and seventy.
