page_text: If this however is prescribed by the pattern the slides are moved backwards and
the hooks m, m³ cross the way of the bolts 7 so that they can be engaged by
suid bolts.
This is effected by levers which are arranged above and below the slides f. f'
being turnable round a bolt and having a blade spring g that acts on the hooks m
and presses them out of the slides when being moved up and downwards. For this
purpose a cam disk r is bolted to the machine, which is fitted with a rod s the ends
of which are connected by cords s¹ to double armed levers journalled on the frame
of the loom. The other ends of these levers have connection to corresponding
sinkers and it will be easy understood that the sinkers when being raised by the
knives by the known action of the cylinders cause an oscillating of the levers !
so that the cam disk r engages the lower lever p which acts the hook to be pushed
upward while its fellow hook escapes, as the upper lever having connection to
the lower one by a rod u is likewise raised. The effect of this operation, which is
illustrated in Figure 7, is the back movement of slide f1 carrying the Figure
cylinder that can now strike the needles. In order to attain the same effect for the
ground cylinder the cam disk r allows the levers p to be pulled down by a spring v,
the upper hook m is then brought in engagement with the carriage and the lower
hook slipped in its normal position, the slide f is carried backwards and the
ground cylinder can strike the needles Figure 8.
Now in order that the carriage h can go forwards again through one of the
turnable hooks is in its way the head of the hooks m, m' is curved and the tossing
piece of the levers p is of spring like action Figure 5, so that the bolt can easy slip
through.

The device thus described can be carried out in different modifications instead of
lodging the same aside the machine as in the present example I can arrange the
slides and their appertainings in a special frame o, which can be mounted behind
the Jacquard machine the cylinders being then carried in frames 6 that have
connection to the slides in the manner shown in Figure 9 of the drawings. I can
also arrange the slides on the head of the Jacquard machine Figure 10 driving the
carriage by the oscillating machine shaft by means of an angle lever y. No
battens are then necessary. The movement of the slides is transmitted to the
cylinders by double armed levers z, which carry them in their lower ends.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what I
claim is:
1. In a Jacquard machine having two cylinders one for ground the other for
figure binding the arrangement and use of slides us f, f' to carry said cylinders
being driven to and fro by a carriage as h, having bolts as 7, said bolts engaging
atationary hooks of tho slides to push them in one direction and engaging
alternately movable hooks as m, m¹ for the contrary movement of the slides said
hooks being acted by levers p with spring tossers and a cam disk as being
turned by sinkers of the machine in the described manner as and for the purpose
described and as shewn in the drawings.
2. In a Jacquard machine having two cylinders, one for ground the other for
figure binding the arrangement and use of the driving device for suid oylinder,
aside, aback or ahead of the machine substantially in the manner as and for the
purpose described.
