in the employment of Messieurs Thornton and Mawby, of Leicester, Hosiery
Manufacturers for an Invention of "IMPROVEMENTS IN MACHINERY AND

PROVISIONAL SPECIFICATION left by the said Henry Clarke at the Office
of the Commissioners of Patents on the 16th October 1882.
HENRY CLARKE of Leicester, in the county of Leicester, in the employment
of Messieurs Thornton and Mawby of Leicester, Hosiery Manufacturers,
"IMPROVEMENTS IN MACHINERY AND APPARATUS APPLICABLE TO HOSIERY
STITCHING MACHINES,"
To a hosiery stitching machine, of the usual construction, carrying a toothed ring
provided with points' upon which the fabric to be stitched is placed, I secure an
excentric on the cam shaft, this excentric gives a reciprocating motion to an
excentric rod which takes onto an axle in a sliding plate or shaft, sliding on or in
studs, secured to or forming part of the main standard of the machine; the plate or
shaft carries an arm having its lower end taking into a slot in or near the cutting
end of a cutter blade rocking on an axle secured in a bracket attached to the ring
cylinder, the cutting edge of the blade moves too and fro over the bracket and
within a recess cut in the top edge of the cylinder, the arm which operates the
cutter blade carries a spring driver, which at each outward movement racks a
notched wheel one tooth, this wheel revolves on an axle carried by a spring bearing
secured to the cylinder, the notched wheel is held by a spring catch or stop.
This wheel firmly holds the fabric down, and close to the outer edge of the
cylinder, while it is being cut. The cutter blade moves too and fro under a fixed
cutter blade secured to and adjustable on, and within the cylinder. By machinery
and apparatus constructed and operated as above described, I am enabled to cut
off the superfluous portion of the fabric, as fast as it is stitched, without stopping
the machine.

HENRY CLARKE of Leicester, in the County of Leicester, in the employment
of Messieurs Thornton and, Mawby of Leicester, Hosiery Manufacturers "IMPROVE-
MENTS IN MACHINERY AND APPARATUS APPLICABLE TO HOSIERY STITCHING
MACHINES"
•
To a hosiery stitching machine of the usual construction, carrying toothed
ring, provided with points upon which the fabric to be stitched is placed, I secure
an eccentric on tlic cam shaft, this eccentric gives a reciprocating motion to an
eccentric rod, which takes onto an axle in a sliding plate or shaft, sliding on or in
studs secured to or forming part of the main standard of the machine, the plate or
shaft carries an arm having its lower end taking into a slot in or near the cutting
end of a cutter blade rocking on an axle secured in a bracket attached to the ring
cylinder, the cutting edge of the blade moves to and fro over the bracket, and
within a recess cut in the top edge of the cylinder, the arm which operates the
cutter blade carries a spring driver which at each outward movement racks n
notched wheel one tooth, this wheel revolves on an axle carried by a spring bearing
secured to the cylinder, the notched wheel is held by a spring catch or stop. This
wheel firmly holds the fabric down and close to the outer edge of the cylinder
while it is being cut. The cutter blade moves to and fro under a fixed cutter
blade secured to and adjustable on and within the cylinder:
By machinery and apparatus constructed and operated as above described, I am
enabled to cut off the superfluous portion of the fabric, as fast as it is stitched,
without atoning the meshing
machine.
Figure 2 is a right side view of the same, and
Figures 3 to 7 inclusive, are plans of separate parts of the same severally
referred to hereafter
Similar letters refer to similar parts throughout the several figures ·
To a hosiery stitching machine of the usual construction carrying a toothed ring
provided with points upon which the fabric to be stitched is placed, I secure an
eccentric A on the cam shaft (a side view of this eccentric is shewn at Figure 7)
the eccentric communicates a reciprocating movement to a rod B, hinged to the
eccentric strap, this rod slides in a bearing secured to the lower side of the bracket
carrying the toothed point ring, the rod B is slotted at its outor end in which a
stud can be adjusted by a lock nut (see Figures 1 and 2), the lower end of the stud
takes into the slotted end of a plato C which may be attached to or it may form
part of a cutting blade C which rocks on an axle under á fixed cutting blade C³,
supported by a bracket attached at one end to the underside of the cylinder or
base plate on which the toothed point ring revolves
The plate C is shewn separately in plan at Figure 4, the moveable cutter
blade C, and fixed cutter blade C is shewn in plan at Figure 5, and the blade C³;
by itself at Figure 6. Within the toothed point ring a bearing is secured to the
cylinder or base plate carrying an axle D on which a boss revolves which forms at
one end a toothed spur wheel D' which gears into the teeth of the point ring, and
t

page_text: at the other end a toothed bevel D³, gearing into a toothed bevel wheel D³ secured
to and revolving with a notched wheel D' on an axle carried by the bracket 0³,
the notched wheel firmly holds the fabric down and close to the outer edge of the
cylinder (or to a spring plate D³ secured to the underside of the cylinder) while it
is being cut. The notched wheel, and spring plate, guides the fabric as it clears
the points of the ring, to the cutter blades, the fabric is prevented from leaving the
points either by its own weight or other cause, before the superfluous portion is
cut off by a guide rod D6 secured to the underside of the axle bearing end of the
bracket C³, the notched wheel D has a groove (see Figure 2) cut in it near its
upper edge in which groove the line of stitching lies while pressed to the spring
plate. The bracket Cattached to the cylinder, wheel D³, plate D³, and rod De
are shewn in their relative positions in plan at Figure 3. By such means as fast
as the fabric on the points is stitched it is guided clear of the points, to the
cutter blades and the superfluous portion of the fabric is cut off as fast as it is
stitched without stopping the machine.
Having thus fully described my said invention, and the manner of performing
the same, I wish it understood that I claim :-
For the grooved and notched wheel D' for holding the stitched fabric in position,
while the superfluous portion is cut off.
In witness whereof I the said Henry Clarke, have hereunto set my hand and
seal, this twelfth day of April in the year of our Lord, One thousand eight
hundred and eighty three.
