Improvements in Card Setting Machines.
We, JOHN HENRY JEFFERYS of Kendall in the County of Westmoreland,
Card Manufacturer, and SAMUEL BEAUMONT and ERNEST BEAUMONT, both of
48 Grande Rue, Roubaix, Departement du Nord, France, 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 :-
This invention relates to machines for setting the dents or teeth of wire cards,
and its object is to provide more certain, accurate and simple means for producing
two bends in each limb of each dent as is already sometimes done, instead of the
single bend more commonly produced.
In a machine constructed according to these improvements, we may employ the
ordinary mechanisms for cutting the wire, producing the crown, inserting the dent
into the foundation and producing the first bend. To produce the second bend, we
arrange to receive the ends of the dent, after they have been inserted through the
foundation and beyond the back-head, upon an adjustable plate or support between
which and the back-head they pass through the hooks of the crookers. Upon the
descent of the crookers in the manner hereinafter described, the bend nearer to the
foundation is formed upon the back-head and the second bend by the crookers,at a point
intermediate between the back-head and the adjustable plate upon which the ends
of the dents are detained. The liberation of the dent from the crookers is effected
by means of a vertically moving truncated wedge or cone which enters between
the crookers and forces them apart. The crookers are returned by a spring to
their original position and the cycle of motions is repeated after the foundation has
been moved by the usual means into the position for the insertion of the next dent.
We will more particularly describe our said invention with reference to the
accompanying drawings in which :-
Figure 1 is a side elevation shewing the general arrangement.
Figure 2 is a side view of the swing frame in which the crookers are carried,
Figure 3 is a vertical longitudinal section taken between the crookers.
Figure 4 is a plan of the swing frame and crookers, and
Figures 6 to 12 inclusive represent details.
A is the frame side of an ordinary card setting machine, B is the driving shaft,
and C the sheet or fillet foundation in which the dents are to be set.
The swing frame D is pivoted to its brackets in the usual manner, but the
crookers are constructed and arranged to be mechanically separated at the proper
moment and to be thereafter closed together by the bow spring F or by an
equivalent spring or springs. Between the crookers there is arranged a fixed
gauge piece G, the function of which is to prevent the limbs of the dents being
drawn together.
Perpendicularly under the gauge piece G, there is arranged a truncated wedge
or cone H, which has vertical oscillating or reciprocal motion imparted to it.
This wedge may be carried on a vertically reciprocating slide, but it is preferred
to mount it as shewn by Figure 1, upon a rocking shaft H', which is oscillated at
the proper moment by the cranked rod I, and the tappet J on the driving shaft.
The swing frame D is oscillated by the cranked rod K, and the tappet L, or
by two equivalent tappets fixed upon the driving shaft B. This tappet, or these
two tappets if two be used, differ from the ordinary tappet employed for oscillating
the swing frame in having two different dwells or heights b, c, instead of c only.
The cycle of motions commences when the rod K is opposite to the centre part of

page_text: the curve a of the tappet. In this position the crookers are at the highest part
of their stroke and the limbs of the dent are inserted through the foundation C
and the hooks of the crookers as shewn by Figure 6. The motion of the tappet
then forces the crookers down to the position shewn by Figure 7, when the dwell b
comes into contact with the rod K and the motion of the crookers ceases
momentarily whilst the wedge H is moved up to the position shewn by Figure 12,
from its normal position shewn by Figure 11. The motion of the tappet continuing,
its higher part c forces the crookers further down into the position shewn by
Figures 8 and 12, when they are fully separated by the entrance between them of
the wedge H, and the two limbs of the dent are thereby freed. The remainder of
the tappet is shaped in the usual manner to restore the crookers to their original
position, Figure 9, whereupon the cycle of motions is repeated. The upper ends of
the crookers, instead of being hooked in the usual manner, are simply turned
inwards at right angles, so that they readily slide off the limbs of the dent when
they are separated by the wedge.
A bracket or arm M, is secured upon the machine frame side in such a position
that the adjustable blade N may be fixed thereon, behind the crookers and the
back-head O, as separately shewn in plan by Figure 10, so that the limbs of
the dent, after they have been inserted through the foundation come over the
upper face of the blade N, upon which they are detained whilst the bends are
being made.
During the descent of the crookers as herein before described, they draw down
the limbs of the dent between the back-head and the plate N, thus producing a
second bend, as shewn by Figures 7 and 8, simultaneously with and in addition to
the first or ordinary bend produced upon the back-head.
The crookers are separated as herein before described, for the liberation of the
dent,. because the second bend prevents their liberation in the ordinary mauner.
For this purpose we may make the central parts P of the crooker slides of flat
spring steel to give them flexibility, and they may be forced together again by
the bow spring F, after the withdrawal of the wedge, but this construction may be
variously modified to produce a like result.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that
what we claim is :-
1. In a card setting machine, a two dwell tappet or tappets on the driving
shaft, a rod connecting the tappet with the swing frame, an adjustable blade at
the back of the crookers, a wedge to separate the crookers for the liberation of
the dent, and a spring or springs to close the crookers, constructed arranged and
operating with the machine substantially as and for the purpose hereinbefore
described and as illustrated by the accompanying drawings.
2. In a card setting machine, the combination and arrangement with the back-
head of an adjustable blade N, between which and the back-head the crookers are
introduced, substantially as and for the purpose hereinbefore described and as
illustrated by the accompanying drawings.
3. In a card setting machine, the combination and arrangement with the swing
frame of a connecting arm and a two dwell tappet or tappets, constructed and
arranged substantially as and for the purpose hereinbefore described and as
illustrated by the accompanying drawings.
4. In a card setting machine, crookers having their hooks formed by single right
angle turns and constructed in such a manner that the hooks may be separated by
the insertion between them of a wedge and restored by a spring or springs,
substantially as hereinbefore described and as illustrated by the accompanying
drawings.
5. In a card setting machine, the combination and arrangement with separable
crookers, of a fixed gauge piece between the crookers, substantially as herein before
described and as illustrated by the accompanying drawings.

page_text: 6. In a card setting machine, the combination and arrangement with separable
crookers of a wedge arranged to enter between them and open them, and a spring
or springs to close them after the withdrawal of the wedge, substantially as
hereinbefore described and as illustrated by the accompanying drawings.
