PROVISIONAL SPECIFICATION.
Improvements in Jacquard Apparatus.
I, RUDOLF BECK of V Hundsthurmerstrasse 27, Vienna, Manufacturer, do
hereby declare the nature of this invention to be as follows
The object of this invention is to enable cards of considerably smaller size
than usual to be employed in Jacquard apparatus constructed for cards of the
ordinary size.
For this purpose there are arranged between the ends of the Jacquard needles,
and the cylinder, and in line therewith, a series of spring-controlled needles, bent
in such manner that the ends which are to be operated by the cylinder are situated
considerably closer together than the Jacquard needles themselves, by which
means the size of the perforated surface of the card may be materially reduced.
These bent needles, which correspond in number to the needles in the Jacquard
apparatus, like the Jacquard needles themselves, pass through a spring case and
a needle board, and at their ends which are adjacent to the Jacquard needles,
are enlarged, or provided with small plates, whereby two needle-ends situated
opposite each other are prevented from slipping off when in operation.
The accompanying drawings illustrate Jacquard apparatus according to this
invention,
Fig. 1 being a vertical longitudinal section and
Fig. 2 a sectional plan.
Fig. 3 is a front view of the needle-plate or board, and
Fig. 4 is a similar view of the spring case whereby the bent needles of the
improved arrangement are controlled.
As shown, the reducing attachment consists of needles a arranged one above the
other in as many tiers or rows as there are tiers or rows of Jacquard needles in the
frame, their number being also equal to the number of Jacquard needles.
The ends a¹ of the needles which pass through the spring case b are arranged at
such distances apart that when the spring case is secured to the ordinary needle
board c of the ordinary Jacquard apparatus (see Fig. 1) each of the ends a¹ of the
bent needles takes up its position within reach of the Jacquard needles c¹.
The ends a¹ of the bent needles are either enlarged or provided with small
plates a² so that, as the needles a are pushed forward (in the direction of the arrow
Fig. 1) it is ensured that they come in contact with the corresponding Jacquard
needles c¹ and force them back.
As shown in the plan, Fig. 2, the needles a are bent so as to bring the ends a³
close together.
The needle-ends a³ pass through a needle board & rigidly connected with the
spring case band project beyond it to a sufficient extent to enable them to be
operated by the cylinder A.
The needle-ends as being, as before stated, arranged close together, the card
appertaining thereto is correspondingly small. By comparing Figs. 3 and 4, the
proportion of the reduction in the size of the cards which is effected by this
invention may be realised and an idea formed of the difference between the
improved small mesh card and the usual coarse mesh caid.
The improved needle plate or board d (Fig. 3) in the example shown, has four
double rows (I to IV) of perforations, and, as shown in Fig. 1, alternate needles in
each row are bent out of the plane of the other needles, which enables the ends a³
to be brought still nearer together. This arrangement, however, is not essential as

page_text: the double rows of perforations (I to IV) may, if preferred be replaced by four
single rows.
To prevent the needles from being bent out of shape, between the spring case b
and the needle board & there is arranged a grate g by the interstices or openings of
which the needles are properly guided or retained in position.
It will be understood that, by means of this invention, any Jacquard apparatus
constructed for cards of the ordinary size may be operated by means of cards
reduced in size according to the present invention by securing to the needle board
of the apparatus herein described.

Improvements in Jacquard Apparatus.
I, RUDOLF BECK, of V Hundsthurmerstrasse 27, Vienna, Manufacturer, 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 object of this invention is to enable cards of considerably smaller size
than usual to be employed in Jacquard apparatus constructed for cards of the
ordinary size.
For this purpose there are arranged between the ends of the Jacquard needles,
and the cylinder and in line therewith, a series of spring-controlled needles, bent in
such a manner that the ends which are to be operated by the cylinder are situated
considerably closer together than the Jacquard needles themselves, by which means
the size of the perforated surface of the card may be materially reduced. These
bent needles, which correspond in number to the needles in the Jacquard apparatus,
like the Jacquard needles themselves, pass through a spring case and a needle
board, and at their ends which are adjacent to the Jacquard needles, are enlarged
or provided with small plates or discs, whereby two needle-ends situated opposite
each other are prevented from slipping off when in operation.
The drawings left with my Provisional Specification illustrate Jacquard apparatus
according to this invention,
Fig. 1 being a vertical longitudinal section, and
Fig. 2 a sectional plan of the improved device.
Fig. 3 is a front view of the needle-plate or board, and
Fig. 4 is a similar view of the spring case whereby the bent needles of the
improved arrangement are controlled.
As shown, the reducing attachment consists of a number of needles a arranged
one above the other in as many tiers or rows as there are tiers or rows of
Jacquard needles in the frame, their number being also equal to the number of
Jacquard needles.
The ends a¹ of the needles which pass through the spring case bare arranged
at such distances apart that when the spring case 6 is secured to the ordinary
needle board c of the ordinary Jacquaid apparatus (see Fig. 1) each of the
ends a¹ of the bent needles takes up a position within reach of a Jacquard
needle c¹.
The ends a¹ of the bent needles are either enlarged or provided with small plates
or discs a² so that, as the needles a are pushed forward in the direction of the arrow
Fig. 1 it is ensured that they come in contact with the corresponding Jacquard
needles c¹ and force them back.
As shown in the plan, Fig. 2 the needles a are bent so as to bring the ends a³
near together.

page_text: The needle-ends a³ pass through a needle board d rigidly connected with the
spring case b, and project beyond such board to a sufficient extent to enable them
to be operated by the cylinder A.
The needle-ends a³ being, as before stated, arranged near together, the card
appertaining thereto can be made correspondingly small. By comparing Figs. 3
and 4, the proportion of the reduction in the size of the cards which is effected by
this invention may be realised and an idea formed of the difference between the
improved small mesh card and the usual coarse mesh card.
The improved card e is perforated in accordance with the perforations of the
needle board d, Fig. 3, so as to suit the ends a³ of the needles, which in the example
shown are arranged in four double rows I to IV, the alternate needles in each row
being bent, as shown in Fig. 1, out of the plane of the other needles, which enables
the ends a³ to be brought still nearer together. This arrangement, however, is not
essential as the four double rows of needle ends may, if preferred, be replaced by
four single rows, and the card e correspondingly altered.
To prevent the needles from being bent out of shape between the spring case b
and the needle board d there is arranged a plate or support g through openings in
which the needles pass and by means of which the needles are properly guided or
retained in position.
It will be understood that by means of this invention any Jacquard apparatus
constructed for pattern cards of the ordinary size may be operated by means of
cards of reduced size by securing to the needle board of the Jacquard frame,
reducing apparatus of the kind herein before described.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. For enabling pattern cards of reduced size to be employed in Jacquard
apparatus the combination with such apparatus, of reducing apparatus comprising
a series of needles a the ends a' of which are arranged opposite to the needles of
the Jacquard apparatus which they are intended to control, while their other
ends a³ upon which the card cylinder is to act, are brought closer together to the
extent to which it is desired to reduce the size of the said cards substantially as
described.
2. Jacquard apparatus provided with supplementary spring controlled needles a
constructed arranged and operating substantially as described and shewn for the
purpose specified.
