PROVISIONAL SPECIFICATION.
An Improved Apparatus for Cutting Spaces in Card Clothing on
Doffer Cylinders of Carding Engines.
WILLIAM PHELON Mechanic Heaton Street Cleckheaton in the County of York do
hereby declare the nature of this invention to be as follows:-
:-
My invention relates to the cutting of spaces in card clothing on condenser doffer
cylinders to form ring cards thereby, without damaging or bending the wire teeth
remaining and forming the sides of the ring card.
For this purpose I use a suitable frame, to which I fit or fix a piece of steel bent
at right angles and having at its extremity a fork with comblike teeth consisting of
two or more cutting edges to suit the "crown" of the card and the width of space to
be cut.
On the inner side of the fork and working close to the face of it, I employ a
cutter or shear also having two or more cutting edges.
This cutter or shear I fix by means of a chuck or other suitable grip to a shaft.
running parallel with the fork."
At the end of the frame furthest from the fork, I fix a stud carrying a pulley,
on the inner side of which I attach by means of bolts and nuts, an eccentric of
small diameter made to move on its support in order to obtain a longer or shorter
stroke, and in order that the cutter or shear may be adjusted to suit the required
width of space to be cut. This eccentric I then connect to the shaft carrying the
cutter or shear, by means of guide rod, lever, and stud, and upon motion being
given to the pulley, this catter is made to oscillate very rapidly before the fork, and
in close proximity to it.
On motion also being given to the doffer cylinder, the fork with the oscillating
cutter is then brought into contact with the teeth of the card clothing, and placed
to the required depth to be cut, so that the wire teeth in the card clothing operated
upon, as they move into the fork, are cut away by the oscillating cutter without
injury to the teeth forming the sides of the ring card clothing.
Although I prefer the oscillating cutter, I can obtain a similar result by means
of a rotary cutter working in conjunction with a steel fork as previously described.

COMPLETE SPECIFICATION.
An Improved Apparatus for Cutting Spaces in Card Clothing on
Doffer Cylinders of Carding Engines.
I WILLIAM PHELON of Heaton Street Cleckheaton in the County of York 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:-
My invention relates to the cutting of grooves or spaces in card clothing on
condenser doffer cylinders, to form ring cards thereby, without damaging or bending
the wire teeth remaining and forming the sides of the ring card-the card clothing
having been previously put upon the cylinder in the form of filleting.
For this purpose I use a suitable frame, to which I secure a piece of steel bont
upward to a suitable angle, and having at its extremity a fork with comb-like teeth,
consisting of two or more cutting edges to suit the crown "of the card and the
width of space to be cut, on the inner side in front of the fork and working close to
and across the face of it, I employ a cutter or shear bent to a similar angle, also

page_text: having two or more cutting edges, this cutter or shear I secure to a shaft running
parallel with the fork by means of a chuck or other suitable grip.
At the end of the frame furthest from the fork, I fit a stud carrying a pulley, and, on
the inner side of the same, I attach by means of bolts and nuts an excentric of small
diameter made to move on its support in order to obtain a longer or shorter stroke,
and in order that the motion of the cutter or shear may be adjusted to suit any
required width of space to be cut.
This excentric I then connect to the shaft carrying the cutter or shear by means of
a guide rod, lever, and, stud, upon motion being given to the pulley, the cutter
is made to oscillate very rapidly in front of the fork, and in contact with it.
On motion being also given to the offer cylinder, the fork with the oscillating
cutter is then brought into contact with the teeth of the card clothing, and placed to
the required depth to be cut, so that the wire teeth in the card clothing operated
upon as they move into the fork are cut away by the oscillating cutter without injury
to the teetli forming the sides of the ring card clothing.
But in order to enable my invention to be better understood, I will proceed to
describe the same by reference to the accompanying drawing.
Fig. 1 represents a side elevation:
Fig. 2 plan of the same, and
Fig. 3 front view of cutter and fork.
A is a frame carrying shaft D to which is fixed cutter C, by means of chuck, E.
B is the fork in front of which the before mentioned cutter, C, oscillates. F is a stud
upon which rotates pulley G carrying adjustable excentric H. The guide rod J
operates the lever K and gives an oscillating motion to the shaft D and also the
cutter C.
Lis a slide rest, and attached to it by means of a stud is a lever M, for the purpose
of moving the apparatus in and out of operation. N is a movable jaw actuated by
screw for securing the machine to any suitable gantry or other support placed in
front of the doffer cylinder to be operated upon.
When the doffer cylinder is made to rotate, the fork B in conjunction with the
oscillating cutter Cis brought into contact with the teeth of the card clothing by
means of lever M, when the teeth are cut away leaving a groove or space, thus
forming a ring card without damage to the edges of the before mentioned ring card
clothing.
Having now particularly described and ascertained the nature of iny said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is,
1st. A fork having two or more cutting edges.
2nd. A cutter having two or more cutting edges and working in contact with the
before mentioned fork for the purpose as herein before described.
