PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Cutting Velvets, Cords, and other
similar Piled Fabrics.
I GEORGE ROGER of 9 Orchard Street Warrington in the County of Lancaster
Master Fustian Cutter do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements upon the knife carrier mentioned and
described in the Provisional Specification accompanying an application for Letters
Patent made by me and filed on the 28th day of January 1887 No. 1350, and is
applicable to automatic apparatus for cutting velvet and other similar piled fabrics
whether the knives are held in a fixed frame and the cloth or fabric driven against
them, or whether the cloth is stretched in a stationary manner and the knives are
mounted in a movable carriage which is caused to travel over the same
The object of this invention is to allow the point of the knife to have a certain
amount of lateral motion without undue strain so as to enable it to follow any curves
or sinuosities that may exist in the race, or any oscillation or lateral movement of the
cloth which may occur during the cutting operation, in addition to the vertical or up
and down movement provided for by the trunnions.
For this purpose instead of fixing the shaft of the knife directly in the boss or
tube by which the trunnions are connected, I make the said boss of a larger
diameter inside and I mount therein a tube which is capable of a limited amount
of lateral oscillation upon a vertical pin or pivot, and in this tube the cutting knife is
fixed, so that the said knife is free to move within certain limits in any direction to
follow the undulations of the cloth, and thus it has the same liberty of motion as when
the knife is held in the hand of the workman.

Improvements in Apparatus for Cutting Velvets, Cords, and other
similar Piled Fabrics.
I GEORGE ROGER of 9 Orchard Street Warrington in the County of Lancaster
Master Fustian Cutter, 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 improvements upon the knife carrier the subject of the
Specification accompanying an application for Letters Patent made by me and filed
on the 28th day of January 1887 No. 1350.
The object of this invention is to allow the point of the knife to have a certain
amount of lateral motion without undue strain so as to enable it to follow any curves
or sinuosities that may exist in the race, or any oscillation or lateral movement of the
cloth which may occur during the cutting operation, in addition to the vertical or up
and down movement provided for by the trunnions.
The nature of my said invention will be readily understood on reference to the
accompanying drawings and the following explanation thereof.
Fig. 1. on the drawings is a side elevation of my improved knife carrier. Fig. 2
is a vertical section, and Fig. 3 a horizontal section of the same.
Instead of fixing the shank a, a of the knife rigidly in the boss or tube b, b or its
equivalent to which the trunnions c, c are connected, I make the said boss hollow and
mount therein the holder d, d so that it shall be capable of a limited amount of lateral
oscillation. It is of smaller diameter than the inside of the boss b, band is mounted
between vertical screws or pivots e, e, and in this holder the shank a, a of the cutting
knife is fixed.
In this manner the knife is free to follow the undulations of the cloth and the
sinuosities of the races, or any lateral movement of the cloth.
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
In automatic knife carriers of the class herein before referred to, the method of
mounting the knife holder so as to be capable of both vertical and lateral oscillation
substantially in the manner herein before described.
Did this 11th day of November 1887
