Office of the Commissioners of Patents on the 28th November 1882.
FREDERICK CUTLAN of Leicester in the County of Leicester Engineer
"IMPROVEMENTS IN HEEL PARING MACHINES FOR BOOTS AND SHOES"
My present invention relates to alterations and improvements in a machine for
paring the heels of boots and shoes for which letters patent were granted to me
bearing date June 18th 1880 N° 5318
The said improvements are as follows the letters and figures refer to the
drawings in the specification of my above named patent
1. I dispense with the roller 1 Fig 1 on the knife stock spindle and I substitute
a clip which clasps the back of the boot or shoe a little above the heel and protects
the upper leather from injury by the friction of the knife stock in case the latter
should come in contact with it. The said clip it attached to and forms the upper
extremity of a vertical rod or spindle which slides through a socket in connection
with the main frame of the machine and is provided with a bolt or other suitable
means of securing it in its place at the proper point.
2nd I make an alteration in the knife stock C. whereby the knife instead of being
fixed rigidly to the knife stock as previously described is now attached to the
underside of an independent block or flap which is hinged to the knife stock and
which carries on its underside a guide which rests upon the heel block T and is
kept in contact with the said block as the knife passes round the heel by the
spring E by this means the cutting edge of the knife is always kept at the right
angle to the work
3rd The machine as previously described is intended for hand power only-
I now add an arrangement for driving the same (so far as a portion of its work

page_text: goes) by steam or other motive power-for this purpose I move the bar U, by a
cam so formed that the said bar is pressed thereby during about one third of a
revolution of the cam shaft and released during the remaining the extremity
of the bar U, carries a friction roller upon which the cam bears and which is kept
up to the cam by a spring-Upon the cam shaft is a large spur wheel gearing into a
pinion upon a second shaft by means of which slow motion is conveyed to the said
shaft.
4th The above described alterations in the knife stock enable me to guide the
knife in passing round the heel by the pressure of the knife stock flap upon the
heel block T only-I therefore dispose with those portions of my former invention
described by me and marked in the drawings by the letters m n o p r r¹ Fig 5

"IMPROVEMENTS IN HEEL-PARING MACHINES FOR BOOTS AND SHOES
"
My present invention relates to alterations and improvements in a machine for
paring the heels of Boots and Shoes for which Letters Patent were granted to me
bearing date December 18th 1880. N° 5318.
The said improvements are as follows:
I dispense with the roller marked in Figure 1 of the drawings to the said Specifi-
cation of the Letters Patent N° 531880 on the knife stock spindle and substitute a clip
or hooked bar A Figure 1 which clasps the back of the boot or shoe a little above the
heel and protects the upper leather from injury by the friction of the knife stock in
case the latter should come in contact with it. The said clip is attached to and
forms the upper extremity of a vertical bar B Figure 1 which slides into a socket
attached to the main framework of the machine and is provided with a bolt C or
other suitable means of securing it in position. Or the said clip may be fixed to
the frame instead of being movable and may be hinged as shewn in Figure 3 which
is a side view of said clip showing face of heel press so that the hinged portion can
be lifted to allow a boot to be placed upon the heel press and then replaced.
I make an alteration in the knife stock C N° 531880 whereby the knife D
instead of being fixed rigidly to the knife stock as therein described is now attached
to the underside of an independent block or flap E' which is hinged or jointed to
the knife stock E and bears upon the heel plate T and is kept in contact with
the said heel plate as the knife passes round the heel by the springs F and G
(E 531880) by which means the cutting edge of the knife is always kept at the
right angle to the work, that part of the hinged flap which comes in contact with
the heel plate T is so shaped as to form a guide.
The machine as previously described is intended for hand power only I now
add an arrangement for driving the same (so far as a portion of the work goes) by
steam or other motive power; for this purpose I move the bar U by a cam V upon
a revolving shaft W so formed that the said bar is pressed thereby during
about /rd of a revolution of the cam shaft and released during the remaining 3/,rd.
the extremity of the bar U carries a friction roller V¹ upon which the cam bears
and which is kept up to the cam by a spring which drives forward the bar U.
Upon the cam shaft is a large spur wheel H gearing into a pinion I upon a second
shaft by means of which slow motion is conveyed to the said shaft as will be well
understood. By this arrangement I can employ motive power for the operation of
attaching the heel the paring and breasting being done by treadle as previously
described the revolution of the cam being so timed that the operator can pare and
breast the boot remove it and place another in position between the thrusts of the
bar U.
The above described alterations in the knife stock enable me to guide the knife
in passing round the heel by the pressure of the knife stock flap upon the heel
block T I therefore dispense with those portions of my former invention described
by me in my said Specification N° 5318 and marked in the drawings by the
letters m n o p i Figure 5.
Having now described my invention and the method of performing the same
I wish it to be understood that what I Claim and desire to protect under the
hereinbefore in part recited Letters Patent is ;
First The employment of the clip or hooked bar A. substantially as and for the
purpose described.

page_text: Second-The fixing of the knife to a loose piece binged or jointed to the knife
stock substantially as described and shewn
Third The combination of the sliding bar U friction roller V¹ cam V and
revolving shaft W substantially as and for the purpose set forth.
In witness whereof I the said Frederick Cutlan have hereunto set my hand
and seal this twenty fourth day of May in the year of our Lord One
thousand eight hundred and eighty three.
