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 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 mechanism 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 striking plate behind the crookers which, at the instant after the
formation of the first bend, and whilst the limbs of the dent are still held by the
crookers, strikes upwards and thus forms the second bend.
The accompanying drawings illustrate in what manner our invention may be
carried into effect and are hereinafter referred to.
Figure 1 is a side elevation shewing the general arrangement.
Figures 2, 3, 4 and 5 shew the successive positions of the dent and striking plate
during the formation of the two bends.
Figure 6 is a side view of the swing frame.
Figure 7 is a vertical longitudinal section through the swing frame.
Figure 8 is an end view, and
Figure 9 is a plan of the swing frame.
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, and the
amount of its motion is regulated by the customary adjusting screw X.
The crookers E are of the ordinary construction and are mounted upon adjust-
able slides F in the carriage G, which slides in the bed H formed or secured upon
the swing frame D.

The striking plate I may be secured directly or indirectly upon the front end of
the cranked bar L adjustably fixed on the lever J fulcrumed upon the side of the
carriage G. Below some part of, or connected with the lever J, there is a short
inclined plane K' formed upon the front end of the adjustable slide K on the
upper face of the carriage. As shewn by Figures 1, 6, 8, and 9, the inclined
plane K is immediately below the end of the cranked bar L, on the opposite end
of which the striking plate I is formed or secured.
At the front end of the bed H there is fulcrumed a short vertical lever M,
the tail of which, when near to the end of the stroke of the swing frame, comes
into contact with an adjustable stop or screw end Figure 1 which tilts it
ultimately into or a little beyond a vertical position as shewn by Figure 7.
Before reaching the vertical position the upper end of the lever will have come
into contact with the end of the carriage and during its subsequent movement will
act to move the carriage backward in its bed, thus withdrawing the crookers over
the ends of the dents. The amount of this motion is regulated by the adjustable
stop or screw O Figure 1. The carriage is restored to its former position by
means of the springs P P.

page_text: The swing frame D is operated as usual by the cam R fixed on the driving
shaft B, through the connecting rod S.
The striking plate I is operated from the cam or tappet T, shewn in dotted
lines Figure 1, which is also fixed upon the driving shaft B. The tappet acts
upon the rocking lever U, in the end of which there is an adjustable stop or
screw V which comes into contact with and moves the tail of the lever J to the
front end of which the striking plate is secured. Thus, the amount of motion of
the striking plate is controlled by the positions of the adjusting screw V and the
inclined plane K.
The stroke of the carriage G and consequently also of the crookers is controlled
by the adjusting screws or screw W Figures 16 7.
The successive steps in the formation of the bends in each dent are illustrated
by Figures 2 to 5 inclusive. As shewn by Figure 2, the dent d is just about to
be inserted, in Figure 3 it has been fully inserted through the foundation and in
Figure 4 the crookers have descended by the motion of the swing frame and have
formed the first bend over the backhead Y. So far the operation has been precisely
similar to that of the ordinary setting machine, but now the striking plate I is
suddenly lifted and forms the second bend in the dents under the hooks of the
crookers as shewn by Figure 5. Immediately thereafter, the lever M comes into
operation as hereinbefore described, and moves the carriage G backwards, thus
drawing the hooks of the crookers over the ends of the limbs of the dent which
are thus liberated. The foundation is then moved as usual into the position for
the insertion of the next dent, the carriage is returned, and the swing frame
brought back to the first position, when the cycle of motions is repeated for the
following dents.
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 :-
1. In a card setting machine the combination and arrangement with the swing
frame and crookers of a striking plate, a sliding carriage carrying the crookers,
and a lever adapted to come into contact with an adjustable stop and move the
carriage backward upon its bed, substantially as and for the purpose herein before
described and as illustrated by the accompanying drawings.
2. In a card setting machine, a striking plate arranged behind the crookers and
operated to ascend and produce a second bend in the dent under the hooks of
the crookers, substantially as hereinbefore described and as illustrated by the
accompanying drawings.
