Improvements in Card Setting Machines.
I, ELIJAH ASHWORTH, of The Moss Brook Works, Collyhurst, Manchester, in
the County of Lancaster, Machine Maker, do hereby declare the nature of this
invention to be as follows:-
My said invention relates to improvements in card setting machines for setting
the teeth of card filleting as is well understood.
In such machines the foundation is conducted between guide wires provided
with adjustable side stops to the feed rollers which feed the foundation through
the machine, the adjustable stops on the guide wires serving to guide the foundation
to the feed rollers. One of the feed rollers is mounted to revolve in fixed bearings,
the other roller being disposed in slots and maintained in position within the
slots by means of hooks, whilst springs are employed to give the requisite nip
to the rollers.
It is found in practice that this method of feeding the foundation through
the machine is subject to a disadvantage inasmuch as the foundation is apt to
deviate from a perfectly straight line in passing through the machine. Owing to
such deviation or lateral movement of the foundation it is impossible to set the
card teeth close to the edge of the foundation. It is customary therefore to adjust
the card setting arrangement so that a strip of fabric ou either side is left void of
teeth to allow for any lateral movement of the cloth. Before the filleting therefore
is wound upon the carding engine cylinder the edges of the foundation must be
pared close to the teeth.
The object of my invention is to provide means whereby the objectionable
tendency to lateral movement of the foundation is overcome, so as to enable the
foundation to be set with teeth close to the edges and thus obviate the necessity
of paring the same.
The
In carrying my invention into effect I secure to the machine in any convenient
manner a guide plate of suitable length. This guide plate is formed with turned
up edges accurately spaced apart to coincide with the width of the foundation. Theso
turned up edges may be adjustable for varying widths of foundation or removable
strips capable of being secured to the guide may be employed for this purpose.
When the foundation has been arranged within the guide à separate plate is placed
upon the foundation and secured in position by means of a screw or screws.
confining plate is adjusted to the thickness of the foundation by means of the
screw and beds close upon the foundation, permitting it to be drawn through the
machine as required but preventing any tendency of the foundation to rise. The
sides of the guide also prevent the foundation from turning in the slightest degree
from a perfectly straight line. The guide is disposed with its delivery end close
up to the nip of the feed rollers so that immediately the foundation leaves the guide
it is gripped by the feed rollers. The guide is provided with slots for the securing
bolts so that it may be moved laterally to compensate for the wear of the parts used
for effecting the lateral traverse of the foundation. An engraved scale and pointer

page_text: is provided to facilitate the lateral adjustment of the guide. As a second part of
my invention instead of mounting one of the feed rollers loosely in slots as described
I mount both feed rollers in fixed bearings.
To effect this I mount the roller previously loose, in bearings formed in blocks
which I secure with screws to the brackets carrying the other feed roller. The
meeting faces of the brackets and blocks are planed and to provide for the vary-
ing thicknesses of foundation the rollers are adjusted relatively to each other by
means of a number of metallic adjusting plates of a definite thickness say 1000th of
an inch, the plates being placed between the meeting faces of the brackets and
bearing blocks.
The use of these metallic packing plates of a known and definite thickness enables
me to obtain the absolute parallelism of the feed rollers which can thus be arranged
to grip equally upon the foundation across its width and further ensure the feeding
of the foundation in an unvarying straight line. Instead of the metallic packing
plates I may adjust the bearing blocks by means of screws or slides.
I wish it to be understood that I do not confine myself to the combined use of
the guide and the improved method of mounting the feed rollers as it may be found
in practice that the use of the guide with the feed rollers mounted as at present
may be sufficient to effect my object. On the other hand the improved method of
mounting the feed rollers so as to obtain the absolute parallelism of the same in
conjunction with the guiding means at present employed may suffice to prevent
any lateral movement of the card foundation. In this case the guide may be
dispensed with.
Instead of the usual fluted metallic feed rollers employed in card setting machines
of this type I may use my improved guide in conjunction with a pair of feed
rollers, the periphery of one of which is covered with card or other teeth so as to
serve as a friction roller the other roller being formed with a plain surface. In
some cases if desired both the rollers may be covered with card or other teeth.

Improvements in Card Setting Machines.
I, ELIJAH ASHWORTH, of The Moss Brook Works, Collyhurst, Manchester, in
the County of Lancaster, Machine Maker, 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 and accompanying
drawings;
My said invention relates to improvements in card setting machines, for setting
the card teeth in the cloth foundation to produce card filleting, as is well understood.
In such machines, the foundation is conducted between guide wires, provided with
adjustable side stops, to the feed rollers which feed the foundation through the
machine, the adjustable stops on the guide wires serving to guide the foundation
to the feed rollers. One of the feed rollers is mounted to revolve in fixed bearings
the other rollers being disposed in slots and maintained in position by hooks, springs
being employed to give the requisite nip to the rollers.
It is found in practice that this method of feeding the foundation through
the machine, is subject to a great disadvantage, inasmuch as the foundation is

page_text: apt to deviate from a perfectly straight line in passing through the machine. Owing
to such deviation or lateral movement of the foundation, it is impossible, without
running off the fabric, to set the card teeth close up to the edge of the foundation
It is customary therefore, to adjust the card setting arrangement so that a strip
of fabric on either side is left void of teeth to allow for any lateral movement of
the cloth.
Consequently, before the filleting is wound upon the carding engine cylinder,
the edges of the cloth foundation must be pared a slight distance from the teeth.
The object of my invention is to provide means whereby the objectionable
tendency to lateral movement of the foundation is overcome, so that I am enabled
to set the card teeth sufficiently near to the edges of the foundation to obviate the
necessity of paring the same
I also so carry and adjust the movable feed roller as to ensure its perfect paral-
lelism with the fixed feed roller.
My invention will be clearly understood from the following description when
read in conjunction with the annexed sheet of drawings.
In the said drawings.
Fig. 1 shows a front elevation of my improved means of guiding the card
foundation to the feed rollers, together with so much of a card setting machine as
is necessary for the comprehension of my invention.

Fig. 3 is a view of the guide bracket, partly in section taken on the line -
Fig. 1.
Fig. 4 is a side elevation showing my improved method of carrying and adjust-
ing the movable feed roller.
Fig. 5 is a front view of Fig. 4.
Referring in the first place to my improved means for guiding the card founda-
tion to the feed rollers.
In carrying my invention into effect I provide a guide bracket A, which I secure
by bolts a, a, to the usual reciprocating carriage B. The bracket A is provided with
an inclined channel or guide 6 formed with turned up edges 1, b.
For varying widths of card foundation, movable strips of metal care employed,
so that a space accurately coinciding with the particular width of foundation may
be readily obtained. As shown in Figs. 1 and 3, the metallic strips are con-
nected to the turned up edge of the guide by means of studs or pins d, d, passing
through holes bored in the turned up edge 61, and secured by means of pinching
Screws e c. To adjust the guide accurately to the width of card foundation, the
foundation is first placed within the channel b. The pinching screws e e are then
slackened and the metallic strips c moved laterally, the pins d d sliding within
their holes, until the strip bears against the edge of the cloth foundation, the
other edge of the foundation bearing against the opposite turned up edge of
the channel b.
When the requisite adjustment has been obtained, the stripe is firmly secured in
position by turning down the pinching screws e e.
When the foundation f has been arranged within the guide channel b, a separate
confining plate g is placed upon the foundation, and secured in position by means
of a screw provided with a conical end engaging with a conical recess in the
late, the screw being provided with a lock nut i. I make the plates in
arying sizes to correspond with the varying widths of card foundation.
The screw is screwed through a cross bar secured to the guide bracket A..
The confining plate g, is adjusted to the thickness of the foundation f by means
of the screw h, such screw also preventing the plate from rising. The plate beds
close upon the foundation, permitting it to be drawn through the machine as
equired, but preventing any tendency of the foundation to rise.
The upturned
ides of the guide b and the strip c, also prevent the foundation from deviating
n the slightest degree from a perfectly straight line.
!

page_text: By these means a channel is provided accurately corresponding to the width
and thickness of the card foundation, as will be more apparent from an inspection
of Fig. 3.
The guide is disposed with its delivery end close up to the nip of the feed
rollers C, C¹, so that immediately the foundation is drawn from the guide it is
gripped by the feed rollers. The guide bracket A is provided with slots ; for the
securing bolts so that it may be moved laterally to compensate for the wear of the
parts used for effecting the lateral traverse of the carriage B.
An engraved scale and pointer may be provided to facilitate the lateral adjust-
ment of the guide A.
Instead of providing adjustable strips c the channel in the bracket may be made
the exact width of the foundation but this would necessitate, the use of a different
bracket for each width of foundation.
As a second part of my invention, instead of mounting one of the feed rollers
loosely in slots as described, I mount both feed rollers in fixed bearings, one roller
tring adjusted towards the other.
This arrangement is shown more particularly in Figs. 4 and 5.
I mount the roller C', previously loose, in bearings formed in blocks k, which
I. secure with set screws to the brackets carrying the other feed roller. The
meeting faces of the brackets and blocks are accurately planed, and to provide for
the varying thicknesses of foundation, the rollers are adjusted relatively to each
other, by means of a number of metallic adjusting plates m of a definite thickness.
say 1000th of an inch, the plates being placed between the meeting faces of the
brackets and bearing blocks as clearly shown in Figs. 2 and 4.
The use of these metallic packing plates m, of a known and definite thickness,
enables me to obtain absolute parallelism of the feed rollers, which can thus be
arranged to grip equally upon the foundation across its width and further ensure
the feeding of the foundation in an unvarying straight line.
By means of my improved guide, and my improved method of mounting the
movable feed roller, the foundation is conducted in such a perfectly straight path
that I am enabled to set the card teeth sufficiently close to the edge of the foundation
to obviate the necessity for any paring of the fabric.
The cost of labour of such paring is thus saved and an economy of material
effected owing to the fact that none of the foundation is cut to waste. Moreover
by using card foundation in which the various layers are woven to the requisite
width, I am enabled to preserve the selvedges uncut and the foundation is thus
left solid to the edges.
I wish it to be understood that I do not confine myself to the combined use of
the guide and the improved method of mounting the feed rollers, as it may be found
in practice that the use of the guide with the feed rollers mounted as at present may
be sufficient to effect my object. On the other hand, the improved method of
mounting the feed rollers so as to obtain the absolute parallelism of the same, in
conjunction with the guiding means at present employed, may suffice to prevent
any lateral movement of the card foundation. In this case the guide may be
dispensed with.
Instead of the usual fluted metallic feed rollers, employed in card setting
machines of this type, I may use my improved guide in conjunction with a pair
of feed rollers the periphery of one of which is covered with card or other teeth,
so as to serve as a friction roller, the other roller being formed with a plain surface.
In some cases, if desired, both the rollers may be covered with card or other teeth.
These card covered feed rollers are well known in certain card setting machines.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
1) As an adjunct to a card setting machine, a guide bracket, formed with a
channel the with of an adine

ing such plate to varying thicknesses of foundation, substantially as described.
3) The improved method of mounting and adjusting the movable feed roller C
