the County of Devon, for an Invention of "AN IMPROVED AUTOMATIC
REGULATOR OR APPARATUS FOR REVERSING THE MOTION OF LEATHER ROLLING
MACHINES
"
PROVISIONAL SPECIFICATION left by the said Edward Wilson at the Office
of the Commissioners of Patents on the 16th September 1882.
EDWARD WILSON, Engineer, of the City of Exeter, in the County of Devon,
"AN IMPROVED AUTOMATIC REGULATOR OR APPARATUS FOR REVERSING THE
MOTION OF LEATHER ROLLING MACHINES
"
The object of this Invention is to effect the reversing of the motion of leather
rolling machines automatically by means of the leather being rolled, as soon as the
roller arrives at or near the edge of the same when at work.
In order to effect this object the machine is constructed as follows:-
From the roller of the rolling machine or its spindle, or from an independent
motion in connection with the machine friction is obtained by a steel band or by
any other suitable means. Connected to this friction band by means of suitable
attachments are two small rollers or feelers. These feclers are arranged so that
one is always in front of the roller of the machine as it works alternately in
opposite directions. The friction of the friction band causes alternately, according
to the direction in which the roller is travelling, the roller or feeler in front of the
same to rest upon the leather.
As soon as this feeler passes the edge of the leather it drops by the friction. The
motion thus obtained is utilized by means of any suitable arrangement, preferably
a skew pawl, to actuate a corresponding wheel or segment of a worm, which in its
turn immediately acts upon those parts of the machine which are designed to
reverse its motion, and which may be of any suitable construction.
As soon as the roller is reversed the other feeler is caused to rest on the leather
by friction, and thus travel in front of the roller until it passes over the edge of
the leather, when it drops in its turn, and engaging with the same pawl as before
thus again automatically reverses the motion of the machine.

EDWARD WILSON, Engineer, of the City of Exeter, in the County of Devon,
"AN IMPROVED AUTOMATIC REGULATOR OR APPARATUS FOR REVERSING THE
MOTION OF LEATHER ROLLING MACHINES
"
The object of this Invention is to effect the reversing of the motion of leather
rolling machines automatically by means of the leather being rolled, as soon as the
roller arrives at or near the edge of the same when at work.
In order to effect this object the machine is constructed as follows:-
From the roller of the rolling machine or its spindle, or from an independent
motion in connection with the machine, friction is obtained by a steel band or by
any other suitable means. Connected to this friction band by means of suitable
attachments are two small rollers or feelers. These feelers are arranged so that
one is always in front of the roller of the machine as it works alternately in
opposite directions. The friction of the friction band causes alternately, according
to the direction in which the roller is travelling, the roller or feeler in front of the
same to rest upon the leather.
As soon as this feeler passes the edge of the leather it drops by the friction.
The motion thus obtained is utilized by means of any suitable arrangement,
preferably a skew pawl, to actuate a corresponding wheel or segment of a worm,
which in its turn immediately acts upon those parts of the machine which are
designed to reverse its motion, and which may be of any suitable construction.
As soon as the roller is reversed the other feeler is caused to rest on the leather
by friction, and thus travel in front of the roller until it passes over the edge of
the leather, when it drops in its turn, and engaging with the same pawl as before
thus again automatically reverses the motion of the machine.
But in order that my Invention may be clearly understood I will proceed to
describe the same by the aid of the accompanying sheet of drawings in which
Fig 1 is a side elevation, and Fig 2 an end view, partly in section of a machine for
rolling leather fitted. with my improved automatic regulator or apparatus for
reversing the motion of the machine.
A is the roller of the machine from which friction is obtained by the steel
band B. The friction may if desired be obtained in any other suitable manner
either from the roller or its spindle, or from an independent motion in connection
with the machine.
Connected to the friction band B by means of the arms C and C³, or other
suitable attachments, are two small rollers or feelers D and D¹, arranged so that
one is always in front of the roller A as it works alternately in opposite directions.
The friction of the band B, when the roller A is travelling in the direction of the
arrow, causes the feeler D in front of it to rest upon the leather.
As soon as this feeler D passes the edge of the leather, the friction between the
roller A and the band B causes it to drop, and the motion thus obtained is utilized
by any suitable means to act upon the parts of the machine which are designed
to reverse its motion, and which may be of any suitable construction.
As soon as the motion of the roller A is reversed, the feeler D¹ is caused by the
friction of the band B to rest on the leather, and thus travel in front of the
roller A until it passes over the edge of the leather, when it drops in its turn, and
the motion obtained is again utilized to automatically reverse the motion of the
machine. Instead of causing the feelers D and D' alternately to rest upon the

page_text: leather by means of friction, any other suitable mechanical means may be employed
for effecting this object.
Having thus described the nature of my said Invention and the manner of
carrying the same into effect, I wish it to be understood that what I claim is:-
The improved arrangement for automatically reversing the motion of leather
rolling machines consisting of the rollers or feelers D and D, arranged so that they
are alternately caused to rest upon the leather and travel in front of the roller A,
and upon passing over the edge of the leather the feeler in front of the direction of
travel of the roller A is caused to drop automatically, the motion so obtained
being utilized to act upon any suitable arrangement of reversing mechanism, all
substantially as herein described and shown in the drawings.
In witness whereof, I, the said Edward Wilson have hereunto set my hand
and seal, this 15th day of March in the year of our Lord One thousand
eight hundred and eighty-three.
