page_text: We MATTHEW WRIGHT, Manufacturer, and JOSEPH FERDINAND, Mechanic both
of Prospect Mills Wibsey, Bradford in the County of York, do hereby declare the
nature of this invention to be as follows:-
This invention relates, to appliances, employed for cutting, and dividing the double
pieces, in the manufacture of plush "seal skins" and other like pile fabrics, the
object being to prevent all vibration of the knife or cutter, and to ensure, the latter
being operated by simple appliances, with minimum expenditure of power required,
and to dispense with the complication of cords, pulley and other appliances heretofore
in use for working the cutter.
According to this our said invention, for purpose aforesaid, we employ a broad flat,
knife, of length somewhat longer than the width of the piece, to be cut, the knife is
received on a bed plate, extending across the loom, near the breast beam, and in the
bed plate, is a longitudinal groove. Attached to the under side of the blade of tlie
knife, or to the carrying piece of the blade, are two or more anti-friction pulleys, of
diameter nearly equal to the width of the groove, in the bed plate, within which
they are received, and whilst preventing any "play" or vibration of the knife,
greatly facilitate, its to and fro endwise or cutting motion, by reducing friction.
Within the said longitudinal slot, are two or more antifriction rollers, placed
across the longitudinal groove, the circumference of the latter rollers, is slightly
above the longitudinal slot, and on these rollers, is carried the knife, or its holding
and carrying plate, which runs on, and over the said rollers, or balls or spheres may
be employed, in the said groove, to act as "ball bearings," for the knife or its
carrying plate, or the knife may slide on the bed plate. Other cross rollers, above the
knife or its holding plate, serve to prevent its rising or lifting.
The endwise, to and fro motion, is imparted to the carrying plate, or to the knife:
(when the latter is made in one piece) by means of a strap eccentric, on the tappet
shaft, the strap of the eccentric, is connected by a rod, with the lower arin, of an
upright lever, working on a stud as fulcrum, the other, and upper end of the lever, iś

COMPLETE SPECIFICATION.
Improvements in Apparatus for Outting Pile Fabrics in Looms.
We, MATTHEW WRIGHT, Manufacturer, and JOSEPH FERDINAND, Mechanic both of
Prospect Mills Wibsey, Bradford in the County of York, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention relates to appliances employed for cutting and dividing the double
pieces, in the manufacture of plush "seal skins" and other like pile fabrics, the object
being to prevent all vibration of the knife or cutter, and to ensure the latter being
operated by simple appliances with minimum expenditure of power required and to
dispense with the complication of cords, pulley and other appliances heretofore in use
for working the cutter.
According to this our said invention for purpose aforesaid we employ a broad flat
knife, of length somewhat longer than the width of the piece, to be cut, the knife is
received on a bed plate extending across the loom, near the breast beam, and in the
bed plate is a longitudinal groove. Attached to the under side of the blade of the
knife or to the carrying piece of the blade, are two or more antifriction pulleys of
diameter nearly equal to the width of the groove in the bed plate, within which they
are received and whilst preventing any "play" or vibration of the knifo, greatly
facilitates its to and fro, endwise or cutting motion, by reducing friction.
Within the said longitudinal slot, are two or more antifriction rollers placed across
the longitudinal groove, the circumference of the latter rollers, is slightly above the
longitudinal slot, and on these rollers is carried the knife, or its holding and carrying
plato, which runs on, and over the said rollers, or balls or spheres may be employed
in the said groove, to act as "ball bearings," for the knife or its carrying plate, or

page_text: the knife may slide on the bed plate. Other cross rollers above the knife, or its
holding plates, serve to prevent its rising or lifting.
The end wise to and fro motion, is imparted to the carrying plate or to the knife,
(when the latter is made in one piece,) by means of a strap eccentric on the tappet
shaft, the strap of the eccentric is connected by a rod with the lower arm of an
upright lever, working on a stud as fulcrum, the other and upper end of the lever is
enlarged so as to form a plate through or in which is cut or formed, a cam or inclined
slot, in which slot is an antifriction runner or bowl, connected with the end of the
knife or its carrying plate, so that at each revolution of the tappet shaft, the strap
eccentric and rod impart to the upright lever a rocking notion, and the cam groove
imparts to the knife an end wise to and fro, or cutting motion. The connecting pile
of the double ground or backed piece, being drawn by the tacking up roller, and
motion, to and against the edgo of the knife, as woven, is cut and severed, producing
the two plush or pile pieces as is well understood.
Such being the nature and object of this our said invention, the following is a
complete description of same, reference being had to the accompanying drawings:
Fig. 1 is a side elevation of part of a loom having our improved cutting apparatus
applied thereto.
Fig. 2 is a front elevation of Fig. 1.
Fig. 3 is a detail of the cutting apparatus drawn to enlarged scale.
Fig. 4. is a plan view of fig. 3.
According to this our said invention for purpose aforesaid we employ a broad flat
knife 1 of length somewhat longer than the width of the piece, to bo cut, the knife 1
is received on a bed plate extending across the loom near the breast beam, and in the
bed plate 2 is a longitudinal groove 3. Attached to the underside of the blade of
the knife 1, or to the carrying piece of the blade are two or more antifriction
pulleys 4-4 of diameter nearly equal to the width of the groove 3 in the bed plate 2,
within which they are received, and whilst preventing any "play" or vibration of
the knife 1 greatly facilitates its to and fro, endwise or cutting motion, by reducing
friction.
Within the said longitudinal slot 3 are two or more antifriction rollers 5-5 placed
across the longitudinal groove 3 the circumference of the latter rollers 5-5 is slightly
above the longitudinal slot 3 and on these rollers 5-5 is carried the knife 1 or its
holding and carrying piece which runs on and over the said rollers 5-5, or balls or
spheres may be employed in the said groove to act as "ball bearings" for the
knife 1 or its carrying piece, or the knife may slide on the bed plate. Other cross
rollers 6, above the knife 1 or its holding piece servo to prevent its rising or
lifting.
The end wise to and fro motion is imparted to the knife 1 or to the carrying piece
(when they are made in one piece) by means of a strap eccentric 7 on the tappet
shaft 8, or on the crank shaft, the strap 9 of the eccentric 7 is connected by a rod 10
with the lower arm 11 of an upright lever 12 working on a stud 13 as fulcrum, the
other and upper end of the lever is enlarged, so as to form a plate 14 through or in
which is cut or formed, a cam or inclined slot 15 in which slot 15 is an antifriction
runner or bowl 16 connected with the end of the knife 1 or its carrying piece, so
that at each revolution of the tappet shaft 8 or crank shaft, the strap eccentric 7 and
rod 10 impart to the upright lever 12 a rocking motion, and the cam groove 15
imparts to the knife 1, an endwise to and fro, or cutting motion. The connecting
pile of the double ground or backed piece 17 being drawn by the taking up
rollers 18-18 and motion, to and against the edge of the knife 1, as woven, is cut
and severed, producing the two plush or pile pieces 19-20 as is well understood.
The knife 1 on its bed plate 2 is mounted at each end on a stud or pin 21 which
passes through the end frame of the loom, and to the bed plate 2 is secured a link 22
the opposite end of which is connected by a screw 23 which passing through a
bracket 24 is "set" and held in position by means of a winged nut 25, so that the
knife 1 and its carrying piece can be adjusted to cut the fabric at all times equally
through the centre of the length of the pile.
