PROVISIONAL SPECIFICATION.
Improvements in Knitting-machines.
I, HEINRICH VERGES, of Mühlhausen, Thuringia, in the Empire of Germany,
Merchant, do hereby declare the nature of this invention to be as follows:-
This invention relates to the Lamb and other parallel knitting-machines and
consists in providing in lieu of the central triangular cam two spring-fingers
arranged to be adjustable in position by means of bolts and also in providing a
guide-piece adapted to protect the points of the said fingers and to assist in guiding
the needles, the said guide-piece being arranged to be moved simultaneously with
one of the said fingers, into and out of a position to come into contact with the
needles by means of one of the said bolts.
In making hose and other tubular goods it is necessary that the needles of each
bed shall be raised whilst the needles are moving in one direction relatively to the
operating-device and that during their motion in the opposite direction the needles
shall remain down and not be brought into an operating-position.
In knitting ordinary sheet goods, however, the needles of one bed are generally
not raised at all. In making "patent" goods the needles of both beds have to be
raised, whilst the carriage is moving in a single direction, the needle beds being
arranged in such a manner as to allow the needles of the two beds to pass each
other. Goods of all these kinds can be made by means of my device.
In the accompanying illustrative drawings,
Figs. 1 and 2, show front elevations of a needle-operating device according to
this invention, the parts being represented in the two figs. in different relative
positions;
Figs. 3 and 4 show respectively a hack elevation and a plan of the same; and
Figs. 5 and 6 show cross-sections of the device corresponding to Figs. 1 and 2
respectively.
In all these figs. the device is for the sake of clearness represented in a vertical
position.
In these drawings A and represent the two fingers, C and D the bolts by
which the fingers A and B respectively are adjusted in position, and E represents
the guide-piece.
The bolt C is arranged on the upper side of the device and is guided so that it
can only move parallel to itself and is provided with a part F adapted to come into
contact with a pin G which projects from the finger A. The two fingers A and B
are mounted to rotate on a stud H and form two sides of a triangle having a base
of variable length. The finger A is pushed towards the triangle K by means of a
spring J. Consequently if the bolt be drawn sufficiently outwards, the finger A
will be caused to bear against the adjacent side of the triangle K, but will yield
when the needles move down along the said side.
The bolt D is similarly provided with a part M adapted to come into contact
with a pin N projecting from the finger B. The spring J normally presses the
finger B inwardly into the position shown in Fig. 2. When the bolt D is drawn
out, the pin N on the finger B is forced outwards by the part M in opposition to
the action of the spring J. The bolt D is also provided with a guide-plate O
which is formed with an inclined slot P. Engaging in this slot is a pin Q
projecting from a two-armed lever S which is pivoted at R and the end S' of which
engages with a cap T secured on the guide-piece E. In consequence of this

page_text: arrangement, if the bolt D be drawn out into the position shown in Fig. 1, the
guide-plate with its slot P will operate the lever S in such a manner that its
end S will move outwards and the guide-piece E will move back into the plate V,
assinning the position shown in Fig. 5.
At the same time the finger B will, in opposition to the action of the spring J, be
brought into contact with the triangle L, thereby putting the spring into tension.
If now, the bolu D he pushed in again so as to resume the position shown in Fig. 2,
the finger B and the guide-piece E will also be brought back into the positions
shewn in Fig. 2, the guide-piece E being then in a position to come into contact
with the needles.
During the working of the knitting-machine the operation of the device is as
follows:-
:-
When the fingers A & B and the triangles and L are in the positions shown in
Fig. 1, the needles will not effectually rire whether the motion of the needle-beds
relatively to the device be in the direction indicated by the arrow or in that
indicated by the arrow 11, the guide-piece E not projecting beyond the face of the
plate V and the points of the fingers A & B abutting against the triangles K & L
With the parts in the positions shewn in full lines in Fig. 2, and the needle-beds
moving, relatively to the operating-device, in the direction of the arrow 11, the
needles move up over the guide-piece an over and past the finger B. They are
When the
then guided down by the triangle K and push back the finger A.
needle-bed moves relatively to the operating-device, in the direction of the arrow I,
the needles move up slightly along the guide-piece E, and are guided by the
finger A into the space between the fingers A & B and the guide-piece E. then,
without having come into an operating-position, they push back the finger 13 and
move down again along the triangle L. Thus, when the needle-bed is moving in
the direction of the arrow I knitting takes place; but when it moves in the
direction of the arrow I no knitting takes place, therefore, with the parts in the
position shown in full lines in Fig. 2 and with the needle-operating device of
the other needle-bed suitably arranged, hose or other tubular goods can be
knitted.
Finally, when the finger A is moved into the position indicated in dotted lines in
Fig. 2, the needles will riso whether the relative motion of the needle-beds be in the
direction of the arrow or in that of the arrow 11. Consequently "patent" goods
will be made, by suitable relative movements of the needle-beds.
The guide-piece E is provided with projecting edges E, behind which are
situate the points of the fingers A & B when most remote from the triangles K
& L, whereby the points are protected as much as possible from being worn by
the needles.
When using a needle-operating device of this kind it is not necessary to turn
the crank completely round when knitting narrower goods than the machine will
produce.

1, HEINRICH VERGES, of Mühlhausen, Thuringia, in the Empire of Germany,
Merchant, 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 the Lamb and other parallel knitting-machines and

page_text: consists in providing, in lien of the usual central triangular cam, two spring, fingers,
arranged to be adjustable in position by means of bolts, and also in providing a
guide-piece adapted to protect the points of the said fingers and to assist in guiding
the needles, the said guide-piece being arranged to be moved simultaneously with
one of the said fingers, into and out of a position to come into contact with the
needles by means of one of the said bolts.
In making hose and other tubular goods it is necessary that the needles of each
bed shall be raised whilst the carriage is moving in one direction and that during
the motion of the carriage in the opposite direction the needles shall remain down
and not be brought into the working position. In knitting ordinary sheet or flat
goods however, the needles on one bed are generally not raised at all. In making
patent" goods the needles of both beds have to be raised whilst the carriage is
moving in a single direction, the needle beds being arranged in such a manner as to
allow the needles of the two beds to pass each other. Goods of all these kinds
can be made by means of a needle operating device constructed and operating
according to this invention.
Referring to the drawings filed with my Provisional Specification:-
Figs. 1 & 2 show front elevations of a needle-operating device according to
this invention, the parts being represented in the two figs. in different relative
positions;
and
Figs. 3 & 4 show respectively a back elevation and a sectional plan of the same;
Figs. 5 & 6 show cross-sections of the device corresponding to Figs. 1 and 2
respectively.
In all these figures the device is for the sake of clearness represented in a vertical
position.
A and B represent the two fingers, C and D the bolts by which the fingers A
and 13 respectively are adjusted in position, and E represents the guide-piece.
The bolt C is arranged on the upper side of the device and is guided so that it
can only move parallel to itself and is provided with a part F adapted to come into
contact with a pin G which projects from the finger A. The two fingers A and B
are mounted to rotate on a stud H and form two sides of a triangle having a base
of variable length. The finger A. is pushed towards the triangle K by means of a
spring J. Consequently, if the bolt C be drawn sufficiently outwards, the finger A
will be caused to bear against the adjacent side of the triangle K, but will yield
when the needles move down along the said side of the triangle.
The bolt D is similarly provided with a part M adapted to come into contact
with a pin N projecting from the finger B. The spring normally presses the
finger Binwardly into the position shown in Fig. 2. When the bolt D is drawn
out, the pin N on the finger B is forced outwards by the part M in opposition to
the action of the spring J. The bolt D is also provided with a guide-plate (
which is formed with an inclined or cam slot P. Engaging in this slot is a pin Q
projecting from a two-armed lever S which is pivoted at R and the end S' of which
engages with a cap T secured on the guide piece E. In consequence of this
arrangement if the bolt D be drawn out into the position shown in Fig. 1, the
guide-plate O with its slot P will operate the lever S in such a manner that its
end S will move outwards and the guide-piece E will move back into the plate V,
assuming the position shown in Fig. 5. At the same time the finger B will, in
opposition to the action of the spring J, be brought into contact with the
triangle L, thereby putting the spring under greater strain. If now, the bolt. D
be pushed in again so as to resume the position shown in Fig. 2, the finger B
and the guide piece E will also be moved back into the positions shown in Figs. 2
and 6, the guide piece E being then in a position to come into contact with the
needles.
During the working of the knitting-machine the operation of the device is as
fellows: :-
When the fingers A and B and the triangles K and L are in the positions shown

page_text: in Fig. 1, the needles will not be raised whether the carringe carrying two needle
operating devices of the kind described be moved in the direction indicated by the
arrow or in that indicated by the arrow II the guide-picce E not projecting
beyond the face of the plate V and the points of the fingers A and B abutting
against the triangles K and L.
With the parts in the positions shown in full lines in Fig. 2 and the carriage
moving to the right or in the direction of the arrow 11, the needles will be moved
up over the guide-piece E and over and past the finger B. They will then be
guided down by the triangle K and will momentarily push back the finger A in
opposition to its spring J. When the earriage moves to the left or in the direction
of the arrow 1, the needles will be moved up slightly along the guide-piece E, and
will then be guided by the finger A into the space between the fingers A and B
and the guide-piece E; then, without having coine into the working position, they
will push back the finger B and move down again along the triangle L.. Thus
when the carriage is moving in the direction of the arrow II with phe parts in the
position shown in full lines in Figs. 2 and 6 knitting takes place; but when it
moves in the direction of the arrow 1 no knitting takes place. With the parts in
the position shown in full lines in Fig. 2 and with the needle-operating device
of the other needle-bed suitably arranged, hose or other tubular goods can be
knitted.
Finally, when the finger A is moved into the position indicated in dotted lines
in Fig. 2, the needles will rise during each movement of the carriage to the right
and lett. Consequently "patent" goods can then be made, by suitably shifting the
needle-beils.
The guide-piere E is provided with projecting edges El behind which are
situate the points of the fingers A and B when most remote from the triangles K
and L, whereby the points are protected as much as possible from being worn by
the needles.
When using a needle-operating device of the kind described it is not necessary to
turn the crank completely round when knitting narrower goods than the machine
will produce.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what I
claim is :-
1. In a parallel knitting-machine of the kind herein referred to, a needle
operating device constructed with two spring fingers A, B, adapted to be operated
and locked by bolts C, D, and one of which hus a tendency to spring outwards, into
contact with its adjacent cam or wing piece and the other to spring inwards or away
from its adjacent cam or wing piece, and a movable guide-piece E adapted to be
operated simultaneously with the spring finger B, the arrangement being such that
when the carriage on which the said device is mounted is travelling to and fro, the
needles can be caused to rise into the working position, or be prevented from rising,
or be raised into the working position when the carriage is moving in one direction
and be prevented from rising when the carriage is moving in the opposite direction
substantially as described for the purposes specified.
2. In a knitting-machine of the kind herein referred to, needle operating
devices, each constructed, arranged and operating substantially as described and
shown.
