of the Commissioners of Patents on the 3rd January 1883.
HENRY CLARKE, of Leicester, in the county of Leicester,
MACHINERY AND APPARATUS APPLICABLE TO STITCHING OR SEWING-MACHINES
"IMPROVEMENTS IN
"
When applying my improvements to what are known as hosiery stitching
machines, or turning off machines, I employ the following parts, namely; a spring
plate attached to the ring cylinder of the machine, this plate guides the fabric after
it is stitched onto the circumference of a toothed wheel, above which is a recessed
circular cutter plate, above the boss of the toothed wheel, on the same axle is a
second toothed wheel carrying a toothed bevel wheel driven by a similar toothed
bevel wheel, on one end of a boss carrying a toothed spur wheel at the opposite
end which gears into the toothed point ring of the machine, the bevel wheel and
spur wheel revolving on an axle adjustable in a slotted bracket secured to the
cylinder of the machine, the second toothed wheel above named gears into a similar
wheel on another axle, below this wheel, and revolving with it, is a circular cutter
blade, the cutting edge of which slides upon the top of the recessed cutter plate
first named, the upper cutter blade is constantly kept sharp by being pressed upon
by an oil stone, emery block, or their equivalent, the axles of the cutter plate and
blade are carried by a bracket secured to the cylinder. By such means I am
enabled to cut off the superfluous portions of the fabric as fast as it is stitched
without stopping the machine.
The same or similar apparatus can be applied to sewing-machines having vertical
needle bars, the cutter plate and blade being carried by a shaft revolving in bearings
secured to the bed or platform of the machine and driven by a toothed wheel
secured on a revolving shaft of the machine, the said toothed wheel gearing into a
similar toothed wheel on the shaft of the cutter plate or blade, or into an
intermediate wheel, driving the shaft of the cutter plate or blade.

When applying my improvements to what are known as hosiery stitching
machines or turning off machines, I employ the following parts, namely a spring
plate, attached to the ring cylinder of the machine, this plato guides the fabric after
it is stitched onto the circumferenco of a toothed wheel, above which is a recessed
circular cutter plate, above the boss of the toothed wheel, on the same axle, is a
second toothed wheel carrying a toothed bevel wheel, driven by a similar toothed
bevel wheel on one end of a boss carrying a toothed spur wheel, at the opposite end
which gears into the toothed point ring of the machine, the bevel wheel and spur
wheel revolving on an axle adjustable in a slotted bracket secured to the cylinder
of the machine, the second toothed wheel above named gears into a similar wheel
on another axle, below this wheel and revolving with it is a circular cutter blade,
the cutting edge of which slides upon the top of the recessed cutter plato first
named, the upper cutter blade is constantly kept sharp by being pressed upon by
an oil stone, emery block or their equivalent, the axles of the cutter plate and
blade are carried by a bracket secured to the cylinder. By such means I am
enabled to cut off the superfluous portions of the fabric as fast as it is stitched
without stopping the machine.
The same or similar apparatus can be applied to sewing machines having vertical
needle bars, the cutter plate and blade being carried by a shaft revolving in
bearings secured to the bed or platform of the machine and driven by a toothed
wheel secured on a revolving shaft of the machine, the said toothed wheel gearing
into a similar toothed wheel on the shaft of the cutter plate or blade or into an
the shaft of the nutter plate or blade
machine
Figure 2 is a right side view of the same, and
Figures 3 to 6 inclusive, are views of separate parts of the same, severally referred
to hereafter.
The corresponding parts in each Figure are indicated by the same letters where
necessary.
When applying my improvements to what are known as hosiery stitching
machines, or turning off machines, I employ the following parts, namely a spring
plate A shewn at Figures 1 and 2, and separately in plan and side view at Figures 3
attached to the ring cylinder of the machine, this plate guides the fabric after it is
stitched onto the circumference of a toothed wheel B shewn in plan and side view
at Figure 4, above which is secured a circular cutter plate C, shewn in plan and
edge view at Figure 5, above the cutter plate is a second toothed wheel D, carrying
a toothed wheel E, the three wheels and cutter plate revolve on an axle secured in
a bracket B' attached to the bed of the machine being driven by a toothed wheel F
on the outer end of a boss the inner end of which carries a similar wheel F' which
gears into the toothed point ring F³, of the machine, the wheels F and F¹ revolve
on an axle secured in a bracket F attached to the cylinder of the machine.

page_text: The wheel D gears into a similar wheel G below which is secured a circular
cutter blade G', the lower side of which as it revolves, slides upon the top of the
cutter plate C first named, the wheel G and blade G¹, revolve on an axle secured
in a bracket G, attached to the underside of the cylinder, the upper cutter blade is
constantly kept sharp by being pressed upon by an oil stone or emnery block H, or
their equivalent, secured on the boss of a grooved pulley H', which revolves on an
axle secured in the bracket G³, its revolution being effected by a cord or gut passed
round it and also round a grooved pulley H2, on the driving shaft of the machine,
the requisite pressure of the stone or block, being obtained by a spring H³ on the
axle above the pulley H. The fabric after it is stitched is prevented from being
pulled off the points in the ring, by its own weight by means of a bracket plate A¹
attached to the bracket B', the fabric passing between the plate A', and the spring
plate A, to the cutter plate C, and cutter blade G'.
Having thus fully described my said invention and the manner of performing
the same, I wish it understood that I Claim.
First. For a revolving circular cutter plate C, and cutter blade G'.
Second. For the spring plate A, toothed wheels D, E, G, F, and F¹, the oil stone H
or its equivalent, the pulley H' and spring H³, the whole operating in combination
and applied to a hosiery stitching machine or turning off machine to cut off the
superfluous fabric, as fast as it is stitched.
In witness whereof I the said Henry Clarke, have hereunto set my hand and
seal this twenty-seventh day of June in the year of our Lord One thousand
eight hundred and eighty three.
