Improvements in Card Setting Machines.
We HENRY HUGO WORTHINGTON, GEORGE ALEXANDER KENNEDY, and
JAMES ARROWSMITH, trading as Horsfall and Bickham, of Bridgewater Works
Pendleton in the County of Lancaster Wire Card Manufacturers, do hereby
declare the nature of this invention to be as follows:-
The principal object of this invention is so to construct a card setting machine
that it will set the teeth of the cards into the back or woven foundation in stripes
leaving intervening spaces without teeth so that although the teeth are set in a
direction parallel with the weft of the same and at right angles to the warp the
stripes of teeth or dents will run in a diagonal direction across the fabric so that
when fixed upon a roller the said stripes will take a spiral direction thereon.
For this purpose we cause the feed box, which feeds the wire to be made into
card teeth, to receive an intermittent motion only thereby forming short lines of
teeth with intervening spaces without teeth.
In order to obtain such intermittent motion we bore a hole in the plate over
which the feed box slides upon its spindle and in this hole we fit a short sliding
bolt which when the teeth or dents are being set into the foundation is retained by
a cranked lever below the surface of the plate and does not impede the action of
the feed lever as it moves the feed box, and we so mount the cam, which actuates
the feed lever, upon the cam shaft that the direct action of the cam against the
said lever draws back the feed box; and a spring brings the lever and feed box
forward to the setting apparatus. When the feeding of the wire is required to
cease for leaving a plain space without teeth or dents in the foundation the before
named bolt is raised to project above the surface of the plate and the hole through
which it works is in such a position that the bolt locks the feed box before it begins
to be moved forwards by the spring.
This locking of the sliding bolt is effected by a spring connected to the above
named cranked lever the other end of which is provided with an inclined projection
working against another incline upon a lever pivotted at or near its centre to the
moving headstock of the machine; beneath the other end of this last named lever
is a drop pin or peg capable of sliding vertically in a suitable boss fixed on the
headstock. The lower end of this drop pin or peg is rounded and rests upon a long
spiral cam, in the form of a roller provided with alternate raised surfaces and
shallow grooves running the whole length of the said roller which is as long as the
guide screw.
The pitch of these spiral cam surfaces must exactly correspond with the angle at
which the rows of teeth and spaces are to be formed across the woven foundation or
back and the diameter of the roller must be such as to allow of an equal number of
raised surfaces and depressions being formed on its periphery.
This cam or "pitch" roller is capable of a slight motion endways and a slow
intermittent revolving motion.
The former motion is required to make the spacing correspond with the twilling
of the teeth, and is accomplished by a grooved boss, or two bosses, fitted on the
axle of the said spiral cam or pitch roller and actuated by a fork or a notched or
slotted plate fixed to or forming part of the plate which is moved by the twilling
motion to slide the guide screw which gives the transverse motion to the moving
.headstock.
The slow intermittent revolving motion is required to present another part of the

page_text: screw
"
"pitch
or cam surface (corresponding as before stated with the angle
required for the rows of teeth and blank spaces) to the before named drop pin or
peg which locks and unlocks the feed box.
This slow intermittent motion corresponds to that given to the take up motion
for the foundation and is effected by a ratchet or toothed wheel on the axle or shaft
of the long cam at the same end as the taking up mechanism by a suitable pawl the
end of which is broad enough to allow for the endways motion before described;
this pawl is or may be moved by the said taking up motion in the following way:
a spring projection on the lever which carries the pawl is caught by a finger on the
change lever and brought into position to be acted upon by a tappet on the tappet
shaft simultaneously with the usual movement by the said tappet shaft of the
twilling, the reversing, and the taking up motions.
It is evident that by changing the above named spiral cam guide roller, we are
enabled to set the teeth in any desired pattern.

Improvements in Card Setting Machines.
We HENRY HUGO WORTHINGTON, GEORGE ALEXANDER KENNEDY and
JAMES ARROWSMITH, trading_as Horsfall and Bickham, of Bridgewater Works
Pendleton in the County of Lancaster Wire Card Manufacturers, 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:-
The principal object of this invention is so to construct a card setting machine
that it will set the teeth of the cards into the back or woven foundation in stripes
leaving intervening spaces without teeth so that although the teeth are set in a
direction parallel with the weft of the same and at right angles to the warp the
stripes of teeth or dents will run in a diagonal direction across the fabric so that
when the latter is cut diagonally into strips or lengths and fixed upon a roller the
said stripes will take a spiral direction thereon.
Our invention will be readily understood on reference to the accompanying
drawings and the following description thereof.
On Sheet 1 Fig. 1 is a sectional elevation and Fig. 2 a plan view of so much of a
card setting machine as is necessary to show our improved mechanism for giving an
intermittent motion to the feed box as hereafter described.
Fig. 3 is a front view partly in section of a detached portion thereof hereinafter
more particularly described.
Fig. 4 shews another detached part (drawn to a reduced scale).
On Sheet 2 Fig. 5 is a front elevation and Fig. 6 a plan view of the mechanism
we employ for governing the above motion in order to regulate the angle at which
the above named stripes of teeth are formed upon the woven foundation.
According to our invention we cause the feed box a which feeds the wire to be
made into card teeth, to receive an intermittent motion only thereby forming short
lines of teeth with intervening spaces without teeth.
In order to obtain such intermittent motion we bore a hole in the plate b over
which the feed box a slides upon its spindle a* and in this hole we fit a short sliding
bolt c which when the teeth or dents are being set into the foundation is retained by
a cranked lever or rod d below the surface of the plate and does not impede the
action of the feed lever e as it moves the feed box, and we so mount the cam f
which actuates the feed lever e upon the cam shaft g that the direct action of the
Le

page_text: cam fagainst the said lever e draws back the feed box a; and a spring / brings
the levere and feed box a forward in the direction of the arrow (Fig. 3) to the
setting apparatus. When the feeding of the wire is required to cease for leaving a
plain space without teeth or dents in the foundation the before named bolt c is
raised to project above the surface of the plate b and the hole through which it
works is in such a position see Fig. 3 that the bolt c locks the feed box before it
begins to be moved forwards by the spring h.
с
This locking of the sliding bolt c is effected by a spring i connected to the above
named cranked lever or rod d the other end of which is provided with an inclined
projection or cranked end d' extending beneath one end of a lever k pivotted at or
near its centre to the moving headstock m of the machine; beneath the other end
of this last named lever k is a drop pin or peg capable of sliding vertically in a
suitable boss n fixed on the headstock m. The lower end of this drop pin or peg?
is rounded and rests upon a long spiral cam o o' in the form of a roller provided
with alternate raised surfaces o for withdrawing the bolt c and shallow grooves o¹
(see Fig. 1) running the whole length of the said roller which is as long as the
guide screw p, the said grooves o' allowing the spring i to raise the bolt c and lock
the feed box a as shewn.
The pitch of these spiral cam surfaces o o¹ must exactly correspond with the
angle at which the rows of teeth and spaces are to be formed across the woven
foundation or back and the diameter of the roller must be such as to allow of
an equal number of raised surfaces o and depressions of being formed on its
periphery.
This cam or "pitch" roller is capable of a slow intermittent revolving motion,
and (if required) of a slight motion endways, which may be requisite to make the
spacing correspond with the twilling of the teeth, and is (or may be) accomplished
by a grooved boss or two bosses fitted on the axle of the said spiral cam or pitch
roller o o' and actuated by a fork or a notched or slotted plate fixed to or forming
part of the plate which is moved by the twilling motion ordinarily employed
to slide the guide screw p which gives the transverse motion to the moving
headstock m.
The slow intermittent revolving motion is required to present another part of the
screw "pitch" or cam surface (corresponding as before stated with the angle
required for the rows of teeth and blank spaces) to the beforenamed drop pin or
peg which locks and unlocks the feed box a as before described.
This slow intermittent motion corresponds to that given to the take up motion
for the foundation and is effected by a ratchet or toothed wheel o' (see Figs. 5
and 6 Sheet 2) on the axle or shaft o³ of the long cam o o¹ at the same end as the
taking up mechanism, by a suitable pawl g the end of which is broad enough to
allow for the end ways motion before described; when such is required this pawl q
is or may be moved by the said taking up motion in the following way: a spring
projection r on the lever which carries the pawl q is caught by a fingers on the
change lever t and brought into position to be acted upon by a tappet u on the
tappet shaft g simultaneously with the usual movement, by the said tappet shaft, of
the twilling, the reversing, and the taking up motions. vis the spring which acts
on the projection which is pivoted at to the end of the lever
It is evident that by changing the above named spiral cam guide roller o o' we
are enabled to set the teeth in any desired pattern.
In order to keep the bolt c always in working order and prevent it from
accidentally sticking we mount upon the sliding headstock a small lever z, see
Fig. 4 one end of which hears or rests upon the crank d' of the bar d and the other
end is acted upon (whilst the feed lever e is held back by the cam f) by a cam w
which raises it and thereby depresses the bar d and withdraws the bolt c
(irrespectively of the action of the cam roller o o') at every revolution of the cam
shaft g thereby keeping the bolt c in motion when not in actual use.
limiting the raising of the said bolt c of the spring i and bar d.

tion and in what manner the same is to be performed we declare that what we
-claim is :-
1. The improved apparatus for setting card teeth in stripes diagonally across
the foundation, substantially as hereinbefore described and illustrated by the
accompanying drawings.
2. In a card setting machine the combination of a feed box having an intermittent
motion imparted thereto with a cam roller, such o o¹, for controlling the pattern of
the stripes of teeth set in the foundation.
