Improvements in or relating to Machines for Cropping Cloth and
like purposes, and to Means for Bevelling the Blade of the
Cutting Part..
We, FRIEND LEE, of Crosland Court, Brow Road, Paddock, Huddersfield, in
the County of York, Mechanic and WALTER CLAYTON, 7 Bank Field Road,
Huddersfield, aforesaid, Mechanic, do hereby declare the nature of this invention
to be as follows:-
This invention relates to that class of machines known in the woollen trade as
cropping machines," and which are employed for cutting or trimming the pile of
the cloth or other fabrics or material to an even lengtb.
Hitherto it has been customary in this class of machine for the cylinder, on
which the blades or cutters are spirally fixed, to be carried in bearings so as to be
capable of only receiving a rotary motion.
Now the object of this invention is to provide means for imparting to the said
cylinder a traversing, that is, a horizontal reciprocating motion in addition to and
simultaneously with the rotary motion, whereby a slicing action is given to the
cutting blades at the same time that they are revolving, for more evenly and
effectively cutting or "cropping" the cloth, or other material operated upon.
According to our invention on one of the ends of the cropping cylinder shaft is
mounted by any suitable means, such as a set screw, key, or the like, a grooved
pulley. Into the groove of the said pulley is made to work the edge of a circular
projection which encircles a hub or boss. The circular projection is cast or other-
wise fixed to its boss or hub at any desired angle to its axis for imparting a
reciprocating motion to the cropping cylinder shaft simultaneously with the rotary
motion thereof.
The shaft or spindle upon which the boss or hub, armed with the circular
projection at any angle to its axis, is carried in a suitable bearing or bearings,
which may be in the form of a bracket, fixed to or forming a portion of the
machine, and on the opposite end of the shaft or spindle is mounted a pulley or
other equivalent driving mechanism whereby a rotary motion may be imparted to the
said shaft or spindle from any rotating part of the machine.
On a rotary motion being imparted to the cropping cylinder, from any
convenient source of power, a traversing motion is simultaneously imparted to it by
the means described.
The above described machines may be applied to the cylinders of other machines
armed with spiral cutting blades on their peripheries.
Instead of removing the knife for sharpening and bevelling the cutting knife, we
simply reverse the rotary motion of the spiral cylinder and pour emery or other
material of a like nature at the back of the cylinder; when the reverse motion is in
progress it sharpens the knife and bevels it.

like purposes, and to Means for Bevelling the Blade of the
Cutting Part.
We, FRIEND LEE, of Crosland Court, Brow Road, Paddock, Huddersfield, in
the County of York, Mechanic, and WALTER CLAYTON, 7 Bank Field Road,
Huddersfield, aforesaid, Mechanic, 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 that class of machines known in the woollen trade as
"cropping-machines," and which are employed for cutting or trimming the pile of
the cloth or other fabrics or material to an even length.
Hitherto it has been customary in this class of machine for the cylinder, on which
the blades or cutters are spirally fixed, to be carried in bearings so as to be capable
of only receiving a rotary motion.
Now the object of this invention is to provide means for imparting to the said
cylinder a traversing, that is, a horizontal reciprocating motion in addition to and
simultaneously with the rotary motion, whereby a slicing action is given to the
cutting blades at the same time that they are revolving, for more evenly and
effectively cutting or "cropping" the cloth, or other material operated upon.
In the drawings hereunto annexed
Fig. 1 is a part elevation, and Fig. 2 an end elevation of this invention.
Figs. 3 and 4 are respectively a front and end elevation of a cropping machine
with this invention applied.
Like parts in all the views are marked with similar letters of reference.
A is the framework of the machine with the moveable headstocks A' (which
carry the cylinder B) hinged to it at a; B the cylinder armed on its periphery with
spiral blades C and mounted upon a shaft G which works in bearings G¹, formed for
its reception in the headstocks A', so as to be capable of being rotated from any
source of power through driving pulley. D, shaft D', pulley D', belting E, and
pulley F, mounted on the end g of the cropping cylinder shaft G as shown.
All the above described parts are of ordinary and well known construction.
On the end g of the cropping cylinder shaft G is mounted by any suitable means,
such as a set screw, key, or the like, a grooved pulley H. Or when desired a
groove h may be cut in or formed on the shaft say for example by mounting and
fixing collars thereon. Into the groove of the said pulley is made to work the
edge of a circular projection I which encircles a hub or boss i. The circular
projection I is cast or otherwise fixed to its boss or hub at any desired angle to its
axis, as shown at Fig. 1, for imparting a reciprocating motion to the cropping
cylinder shaft G simultaneously with the rotary motion thereof.
The shaft or spindle J upon which the boss or hub i-and which is armed with the
circular projection I at any angle to its axis,-is carried in a suitable bearing or
bearings K which may be in the form of a bracket or brackets,-adjustable or
otherwise, fixed to the headstock A¹ as shown at Figs. 3 and 4, and on the opposite
end of the shaft or spindle J is mounted a pulley L or other equivalent driving
mechanism whereby a rotary motion may be imparted to the said shaft or spindle J
from any rotating part of the machine, such as for instance from pulley M on
spindle N through belt or band O, which passes over pulleys M1 M² mounted
(adjustably or otherwise) on spindles fixed to the projecting part A' of framework A;
motion being imparted to the pulley M from pulley P on driving shaft of machine,
through belt or band Q to pulley R mounted on same spindle N as pulley M.
In the drawing two slotted brackets J¹ J' are shown. The bracket J' to which

page_text: bearing K is attached is shown capable of vertical as well as horizontal adjustment
by means of the slots and bolt j³.
On a rotary motion being imparted to the cropping cylinder, from any
convenient source of power, say through driving pulley D, a traversing,-that is a
reciprocating,-motion is simultaneously imparted to it by the circular projection I
having motion conveyed to it by the means described.
If desired the projection I may be formed on the cropping cylinder shaft G and
the recess or groove / formed in the hub or boss i.
Other parts of the cropping machine not described or illustrated are of the usual
and ordinary construction.
The above described machines may be applied to the cylinders of other machines
armed with spiral cutting blades on their peripheries.
Instead of removing the knife for sharpening and bevelling the cutting knife, as
is customary, all that is required when this invention is applied is to simply reverse
the rotary motion of the spiral cylinder and pour emery or other material of a like
nature at the back of the cylinder; when the reverse motion is in progress it
sharpens the knife and bevels it.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
In a machine for cropping cloth and the like, substantially such as herein
described, the combination with the cropping cylinder of a grooved pulley, or its
equivalent, mounted, formed, or fixed on the cropping cylinder shaft, so as to be
capable of engaging with a circular projection, such as 1, arranged at an angle to
the axis of the spindle or shaft upon which it is mounted, or vice versa, said spindle
or shaft being attached by suitable bracket or brackets-adjustable or otherwise,―to
the headstock A' and caused to rotate by the means described-all of which parts
are arranged substantially as and for the purposes herein set forth.
Dated this Thirtieth day of June 1896.
