I DUGALD SCOTT of 12 York Street Manchester in the County of Lancaster
Manufacturer do hereby declare the nature of this invention to be as follows:-
This Invention relates to the cutting of the pile of weft pile velvets, cords, or other
piled fabrics wherein the pile is cut in the direction of the warp threads, and the
object of the invention is to construct an entirely automatic or self acting machine
for that purpose.
This I propose to effect by combining a modification of the apparatus for which I
applied for Letters Patent No. 5643 on the 24th day of April 1886, with an improved
automatic sliding knife carrier for which an application for Letters Patent bearing
date January 28th 1887, No. 1350, has been filed by George Roger the inventor
thereof.
The general construction and arrangement of the apparatus employed for drawing
the cloth to and fro against the knife or knives is substantially the same as that
described in the Specification (No. 564388) before referred to with the following
additions thereto.
Upon the two metal tension rollers between which the cloth is cut I support a light
frame fitted beneath with two semi-circular notches or bearings at each end which rest
upon the surface of the metal tension rollers and thus carry the said frame above the
cloth This frame is provided with projecting guides (capable of adjustment) against
which the two selvages of the cloth move by which means the frame is caused to
follow any movement or curvature of the cloth laterally as it passes along; the friction
of the semi-circular or forked bearings on the revolving rollers being almost inap-
preciable-This frame is fitted with slides (transversely to the cloth) upon which is
mounted a bridge piece or carriage upon which are fixed the side bearings carrying
the trunnions or slides of the automatic knife carrier or carriers before mentioned.
The knife carrier is fitted with a mechanical automatic stop motion as described in
the Provisional Specification No. 1,350 of 1887 filed by the said George Roger or
with an electric stop motion described in the Provisional Specification filed by me
CD077

page_text: bearing even date herewith so that in the event of any fault or accident the automatic
sliding movement of the knife caused thereby will instantly stop the machine, or instead
thereof, or in addition thereto, means may be provided for the stoppage of the machine
by the hand or foot of the operator or attendant.
When the first race or races have been cut from one end of the cloth to the other,
before reversing the movement of the cloth, the position of the knife or knives on the
side bearings must also be reversed accordingly.
In order to allow of the knives and their carriage being moved in a transverse
direction after each cut, so as to be enabled to "set in" the knife or knives into a
fresh race (or a fresh set of races) the frame is provided with two parallel screws
connected together by bevil gear and working through nuts fixed to the carriage and
provided with a handle or hand wheel for adjusting the same.
This motion may also be made automatic by attaching a peg or pin or a loop or other
projection to the cloth, near to each end thereof, which by coming against a star wheel
or other similar device shall at the end of each cut give motion to the bevil gear and
thus cause the required lateral adjustment to be given to the knife or knives according
to the number of races to be passed over before making the succeeding cut.
I do not wish to bind myself to cut the pile in both directions as (if preferred) it
may be cut only in one direction and the cloth may be made to run back at a greatly
increased speed.

page_text: Improvements in Apparatus for Cutting the Pile of Velvets, Cords,
and other similar Piled Fabrics.
I DUGALD SCOTT of 12 York Street Manchester in the County of Lancaster
Manufacturer 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 the cutting of the pile of weft pile velvets, cords or other
piled fabrics wherein the pile is cut in the direction of the warp threads, and the
object of the invention is to construct an improved machine for that purpose.
This propose to effect by modifying the apparatus, the subject of the Letters
Patent No. 5643 of 1886, as hereinafter described and by combining such apparatus
when so modified with the improved automatic sliding knife carrier for which an
application for Letters Patent bearing date January 28th 1887, No. 1350, has been
filed by George Roger, the inventor thereof.
The nature of my present invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference to
the sheet of drawings hereunto annexed and the following explanation thereof.
Fig. 1 on the drawings is a vertical section, and Fig. 2 a plan view of so much of
the said machine as is necessary to illustrate my present invention.
The general construction and arrangement of the apparatus employed for drawing
the cloth to and fro against the knife or knives is substantially the same as that
described in the Specification (No. 564386) before referred to with the following
additions thereto.
Upon the two metal tension rollers a, a between which the cloth is cut I support a
light frame b, b fitted beneath with two notches or bearings c, c at each end which
notches may be semi-circular or of any other suitable form, and rest upon the surface
of the two metal tension rollers a, a and thus carry the said frame b, b above the
cloth.
This frame b, b is provided with projecting guides d, d (capable of adjustment)
against which the two selvages of the cloth move (see Fig. 2) by which means the
frame is caused to follow any movement or curvature of the cloth laterally as it passes
along, the friction of the notched bearings c, c on the revolving rollers a, a being
almost inappreciable.
This frame b, b is fitted with slides e, e (transversely to the cloth) upon which is
mounted a bridge piece or carriage f, f upon which are fixed the side bearings carrying
the trunnions or slides of the automatic knife carrier or carriers before mentioned.
The knife carrier may be fitted with a suitable stop motion by preference an electric
stop motion such as is described in the Specification No. 220787 filed by me, and
bearing even date herewith, so that in the event of any fault or accident the automatic
sliding movement of the knife carrier caused thereby will instantly stop the machine, or

page_text: instead thereof, or in addition thereto means may he provided for the stoppage of the
machine by the hand or foot of the operator or attendant.
When the first race or races has or have been cut from one end of the cloth to the
other, before reversing the movement of the cloth, the position of the knife or knives
on the side bearings must be reversed accordingly.
In order to allow of the knives and their carriage f, being moved in a transverse
direction after each cut, so as to be enabled to set in "the knife or knives into a
fresh race (or a fresh set of races) the frame b, b is provided with two parallel
screws h, connected together by bevil gear i, i and working through nuts k, k fixed
to the carriage and provided with a handle or hand wheel 1, for adjusting the
same (see Fig. 2). Or if preferred it may be simply adjusted by hand.
This transverse motion may also be made automatic by attaching a peg or pin, or a
loop or other projection to the edge of the cloth, near each end thereof, which by
coming against a star wheel or other similar device is at each end of the cut caused to
impart motion to the bevil gear and thus cause the required lateral motion to be given
to the knife or knives according to the number of races to be passed over before
making the succeeding cut.
I do not confine myself to the cutting of the pile in both directions as (if preferred)
it may be cut only in one direction and the cloth may be made to run back after each
cut at a greatly increased speed.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is
First. The improved apparatus for cutting the pile of velvets, cords, and other
similar piled fabrics consisting in the combination of the aforesaid modification of the
pile cutting machine described in my Specification No. 5643 of 1886 with the sliding
knife carrier described in the Specification of the said George Roger No. 1350 of
1887, substantially in the manner hereinbefore described and illustrated by the
drawings annexed, and
Secondly. I claim the peculiar construction and application of the frame b, b
supporting the knife carriage, substantially as and for the purposes hereinbefore set
forth.
