page_text: LETTERS PATENT to William Spencer Coon, of the City of Rochester,
County of Munroe and State of New York, United States of America,
for the Invention of "AN IMPROVED METHOD OF AND APPARATUS FOR
APPLYING POWER TO THE RUNNING OF MACHINERY AND TOOLS, WHEREBY SUCH
MACHINERY OR TOOLS MAY BE ADJUSTED TO ANY DESIRED ANGLE IN USE.”
Sealed the 4th October 1870, and dated the 12th April 1870.
PROVISIONAL SPECIFICATION left by the said William Spencer Coon
at the Office of the Commissioners of Patents, with his Petition,
on the 12th April 1870.
I, WILLIAM SPENCER COON, of the City of Rochester, County of
Munroe and State of New York, United States of America, do hereby
declare the nature of the said Invention for "AN IMPROVED METHOD OF AND
APPARATUS FOR APPLYING POWER TO THE RUNNING OF MACHINERY AND TOOLS,
WHEREBY SUCH MACHINERY OR TOOLS MAY BE ADJUSTED TO ANY DESIRED ANGLE IN
USE, to be as follows:-
"
This Invention consists in so arranging the operating parts that they
may be turned to any desired angle to present the tool or instrument
properly to the work, either in front of or at the side of the operator.

page_text: A suitable frame is provided having a turntable or equivalent device
at the top, on which is mounted the machinery or the tool by which
the work is to be performed. This table turns on friction rollers attached
to a metallic rim secured to the table. A branched bearing is attached
to the under side of the table having a hub adjustable on a central
spindle by means of a set screw, or otherwise, by which means the
turntable is adjusted higher or lower. A scroll bearing extends across
the frame of the machine under the turntable, the same being adjustable
higher or lower by means of slots made therein with screws to secure it
in place. A portion of this scroll is made concentric with the spindle
having a slot formed therein, through which passes the elbow of a right-
angled hanger, also suspended from the under side of the turntable and
holding a band wheel by which the motion is applied from a motive
power below. The hanger is secured to the scroll by a spring and nut
or other device. A pitman rod extends down from a crank of the band
wheel to the treadle, where it is connected to a rocking plate by a
double joint. This rocking plate is pivoted on the under side of the
treadle, and has an arm with an eye, through which passes a bent rod.
At the opposite end the said bent rod is swivelled to a joint piece,
which in turn is pivoted in the lower end of the spindle, thus forming
another double joint. The outer end of the rocking plate is formed into a
clasp which embraces a concentric portion of the treadle plate to hold it
in place. Power applied to the treadle is transferred to the band wheel
and thence to the machinery to be operated. To change the angle of
the machinery or tool the turntable is simply revolved. This action
also turns the spindle and with it the hanger and band wheel, It also
causes the bent rod to slide through the eye of the rocking plate, and
causes the latter to turn in the same manner and to the same degree as
the turntable. The position of the parts does not affect the action of
the treadle owing to the double joints. Any equivalent device may be
used as a substitute for the treadle. The edges of the treadle rest in
ways or bearings which allow it to be adjusted forward or back and
secured in any position by set screws. The ways turn on the treadle
rod, which is bent or depressed in the centre, and they are held by
collars fitting on the said rod.

filed by the said William Spencer Coon in the Great Seal Patent
Office on the 12th October 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
SPENCER COON, of the City of Rochester, County of Monroe and State
of New York, United States of America, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twelfth day of April, 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 me, the said William Spencer Coon, Her special
licence that I, the said William Spencer Coon, my executors, adminis-
trators, and assigns, or such others as I, the said William Spencer
Coon, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times there-
after 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 "AN IMPROVED METHOD OF AND APPARATUS FOR APPLYING POWER TO THE
RUNNING OF MACHINERY AND TOOLS, WHEREBY SUCH MACHINERY OR TOOLS MAY BE
ADJUSTED TO ANY DESIRED ANGLE IN USE," upon the condition, amongst others,
that I, the said William Spencer Coon, my executors or 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.
NOW KNOW YE, that I, the said William Spencer Coon, 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, reference being had to the accompanying
Drawing forming a part of this Specification:-
This Invention consists in so arranging the operating parts that they
may be turned to any desired angle to present the tool or instrument
properly to the work, either in front of or at the side of the operator.

Figure 1 is a front elevation of the said apparatus; Figure 2 is a
horizontal section on the line x, x, Figure 1; Figures 3 and 4 illustrate
detached portions of the said apparatus. Like letters indicate the same
parts throughout the Drawing.
A suitable frame A is provided having a turntable B or equivalent
device at the top, on which is mounted the machinery, or the tool, by
which the work is to be performed. This table turns on friction
rollers a attached to a metallic rim C secured to the table. A branched
bearing is attached to the under side of the table B having a hub e
adjustable on a central spindle E by means of a set screw d, or other-
wise, by which means the turntable is adjusted higher or lower. A
scroll bearing G extends across the frame of the machine under the
turntable, the same being adjustable higher or lower by means of slots
made therein, with screws fto secure it in place. A portion of this
scroll is made concentric with the spindle, having a slot formed therein,
through which passes the clbow of a right-angled hanger I, also sus-
pended from the under side of the turntable, and holding a band wheel
L, by which the motion is applied from a motive power below. The
hanger I is secured to the scroll by a spring K and nut i, or other
device. A pitman rod M. extends down from a crank of the band
wheel to the treadle P, where it is connected to a rocking plate O by a
double joint N. This rocking plate is pivoted on the under side of the
treadle, and has an arm p with an eye through which passes a bent
rod Q. At the opposite end the said bent rod is swivelled to a joint
piece R, which in turn is pivoted in the lower end of the spindle, thus
forming another double joint. The outer end of the rocking plate is
formed into a clasp which embraces a concentric portion of the treadle
plate to hold it in place. Power applied to the treadle is transferred to
the band wheel and thence to the machinery to be operated. To change
the angle of the machinery or tool the turntable is simply revolved.
This action also turns the spindle and with it the hanger and band
wheel. It also causes the bent rod to slide through the eye of the
rocking plate, and causes the latter to turn in the same manner and to
the same degree as the turntable. The position of the parts does not
affect the action of the treadle owing to the double joints. Any equi-
valent device may be used as a substitute for the treadle. The edges

page_text: of the treadle rest in ways or bearings V which allow it to be adjusted
forward or back, and secured in any position by set screws.
The ways
turn on the treadle rod H, which is bent or depressed in the centre, and
they are held by collars W fitting on the said rod.
Having thus fully described my said Invention, I wish it understood
that I claim, the method of applying power by means of the herein
described apparatus, substantially as set forth for the purpose specified.
