page_text: mounted in a slotted bearing l. The lever is hinged to the carriage g of the
knitting-machine in such a manner as to be capable of being turned in an upward
direction but is normally pressed by a spring m (Figs. 2 and 3) into the groove i.
The disengagement of each lever k from its groove i for the purpose of
throwing the corresponding knitting-machine out of operation, is effected by
raising the lever k by means of a bar o, which is movable parallel to the rod f.
The bar o is formed with inclined slots n in which engage stationary pins p so
that by moving the bar o lengthwise in a suitable direction, the bar is raised.
By means of a spring q, the bar o is drawn into the end position in which the
lever is disengaged; it is held in the other end position by a lever "', which
is pressed by a springs (Fig. 3) into a notch in the bar o, whereby the
lever is allowed to be held in the groove i in the rod f. A very slight
pressure on the forward end of the lever r is sufficient to cause it to move out
of the notch t so as to abandon the bar o to the action of the spring q. By
means of a hand lever u, the bar o can be moved in the opposite direction to
that of the pull of the spring 9 in such a manner that its groove t enters into
engagement with the lever r. Each knitting-machine is provided with a separate
apparatus such as that just described for throwing it into and out of operation.
Each stopping apparatus may be connected with an automatic stroke-counter, for
the purpose of stopping the machine after any predetermined number of strokes
has been made. This is effected by causing the lever r to be pressed downwards
by a plunger M (Figs. 4 and 5) when the desired stroke is indicated by the stroke
counter.
This automatic stopping-apparatus is fully shown in Figs. 6 to 12, inclusive and
is constructed as follows.
A counting-wheel B mounted on a plate A is provided say with one hundred
teeth and is actuated by a lever D through the medium of a spring pawl Ca
pin E on the lever D being connected in a suitable manner with the reciprocating
knitting-machine the arrangement being such that at each oscillation of the lever D,
the counting-wheel B advances to the extent of one tooth. F is a detent for pre-
venting the counting-wheel from turning in a backward direction. G is a brake
carrying an index for use in connection with graduations on the wheel B. By means
of the counting wheel B, a tappet H is rotated, and strikes at every revolution
against a projection I on a slide K, and moves the latter down in opposition to a
spring K. The movement of the slide K is transmitted through a pawl L to the
above mentioned plunger M which is provided with teeth M' for engaging with the
pawl L, and with teeth M² for engaging with a spring M which serves for steadying
and supporting it. The plunger M is marked at the top with divisions which can
be read off by means of an index N and these divisions are such that by the down-
ward movement of the plunger M.to the extent of one of the teeth M' (which is
effected by a complete revolution of the counting wheel B), the plunger is caused
to move down to the extent of hundred divisions. When the plunger M has
reached a position such that the index N is opposite the last division, one revolution
of the counting-wheel B which is equivalent to one hundred oscillations of the
lever D, is sufficient to cause the plunger M to force down lever and disengage
the bar o which is then drawn back by the spring 9 (Figs. 1 and 2) in order to put
the corresponding knitting machines.
By the arrangement described it will be seen that each knitting machine can be
thrown out of operation after making any desired number of strokes within the
range of the apparatus.
"
In order to combine the stopping or disengaging apparatus with a "shogging
device for the production of "shogged" goods (ie. with zig-zag or Vandyke
designs), a third bar O (Figs. 13 to 16) inclusive is arranged in bearings O¹ and
is provided with two stops O. A clip P arranged above the pawl k or its bearing 1,
is furnished with a knob P¹, and is intended near the ends of the reciprocation of
the frame
1,9%
to strike against the projections 0%, and thereby operate the
"shogging" device; when the clip P is raised, it has no action upon the stops O'

and 02. The bar O has two inclines Q which are placed close together so as to
leave a space between them; they serve to move up and down a ratchet.. The
ratchet R is pivotted at R' to the machine frame and carries a pawl R² which
engages in ratchet-wheel S¹ attached to the "shogging" wheel S; the pawl R³ is
kept in gear with the teeth of the wheel S by a spring R³. The "shogging"
wheel S is provided with a rim both edges of which are furnished with teeth S²;
and these teeth are so arranged that the spaces S³ on one edge are opposite to the
teeth on the other and that the cross sections of the rim through the teeth are the
same width wherever they are taken. Against both sides of the rim there bear
pins T which are provided with rollers and are mounted on a lateral projection T¹
of one of the needle beds U. When the bar O is moved by the clip P the
ratchet R is first raised by one of the inclines Q and then pressed down by the
other incline to such a degree as to rotate the shogging wheel S to the extent of a
tooth.
The clip P is constructed and arranged in such a manner that it also is raised by
means of the pawl K when the latter is lifted out by the bar o. By this means
the "shogging" device is disengaged at the same time as the driving apparatus. In
order to prevent over-rotation of the " shogging " wheel S, a brake block V
mounted on a spring V₁ bears against the periphery of the wheel S.

COMPLETE SPECIFICATION.
Apparatus for Driving Knitting Machines and for Controlling the
Working of such Machines.
I, ERNST CLAES, of Muhlhausen, Thüringen, Germany, Knitting-machine
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 :-
This invention has reference to apparatus for driving a number of knitting
machines arranged in a straight row, the apparatus being such that each knitting-
machine can be thrown into and out of operation as desired; to apparatus for
throwing each of the aforesaid machines out of operation when a predetermined
number of strokes has been made; and also to means by which the "shogging"
device of each knitting-machine is automatically operated in such a manner that
one of the needle beds is automatically "shogged" in relation to the other
needle-bed at the required time.
In the illustrative drawings, filed with my Provisional Specification,
Fig. 1 is a front elevation of the driving-apparatus for a number of knitting
machines, the arrangement for operating the "shogging" device being omitted.

Ji
Fig. 15 is a section on the line G G, Fig. 14 looking towards the knitting
machine; and
Fig. 16 is a section on the line H H, Fig. 14 looking towards the shifting wheel.
The construction and arrangement of the driving apparatus is as follows:-
The crank-disc a (Figs. 1 and 2) carries on its rear side the crank-pin b which
by means of the connecting rod e reciprocates the cross-head d in the guides e
By arranging the crank pin b behind the crank-disc a the latter serves as a pro-
tection for the moving mechanism.
The cross-head d is attached io a connecting rod f, which is guided in suitable
bearings behind the knitting-machines and serves for reciprocating the frames g of
the several knitting-machines. The rod is provided on its upper edge, at
distances corresponding to the position of the knitting-machines, with pairs of
inclines h, each of which is separated by a groove i. Into each groove i there
enters a lever k, which is secured to the sliding carriage g of the corresponding
knitting machine so that when it is in engagement with the groove i, it recipro-
cates the said carriage frame.
In order to prevent the lever k from being bent when moving the carriage 9 it is
mounted in a slotted bearing 1. The lever kis hinged to the carriage 9 of the
knitting-machine in such a manner as to be capable of being turned in an upward
direction, but is normally pressed by a spring m (Figs. 2 and 3) into the groove i.
The disengagement of each lever k from its groove i for the purpose of throwing
the corresponding knitting-machine out of operation, is effected by raising the
lever k by means of a bar o which is movable in a direction parallel to the rod f.
The bar o is formed with inclined slots n in which engage stationary pins p so that
by moving the bar o lengthwise in a suitable direction, the bar is raised.. By
means of a spring 9, the bar o is drawn into the end position in which the lever k is
disengaged; it is held in the other end position by a lever r, which is pressed by a
springs (Fig. 3) into a notch t in the bar o, whereby the lever k is allowed to be
held in the groove i in the rod f. A very slight pressure on the forward end of
the lever is sufficient to cause it to move out of the notch t so as to abandon the
bar o'to the action of the spring 9. By means of a hand lever u, the bar o can be
moved in the opposite direction to that of the pull of the spring o in such a manner
that its groove t enters "into" engagement with the lever r. Each knitting machine
Is provided with a separate apparatus such as that just described for throwing it
into and out of operation.

Tito
Each stopping apparatus may be connected with an automatic stroke-counter, for
the purpose of stopping the machine after any predetermined number of strokes
has been made. This is effected by causing the lever r to be pressed downwards
by a plunger M (Figs. 4 and 5) when the desired stroke is indicated by the stroke
counter.
=
This automatic stopping-apparatus is fully shown in Figs. 6 to 12, inclusive and
is constructed as follows.
A counting wheel B mounted on a plate A is provided say with one hundred
teeth and is actuated by a lever D through the medium of a spring pawl C, and a
pin E on the lever D is connected in a suitable manner with the reciprocating.
knitting-machine, the arrangement being such that at each oscillation of the
lever D, the counting-wheel B advances to the extent of one tooth. F is a detent
for preventing the counting-wheel from turning in a backward direction. G is a
brake carrying an index for use in connection with graduations on the wheel B.
By means of the counting wheel B, a tappet H is rotated, and strikes at every
revolution against a projection I on a slide K, and moves the latter down in
opposition to a spring K₁. The movement of the slide K is transmitted through a

page_text: pawl L to the above mentioned plunger M which is provided with teeth M¹ for
engaging with the pawl L, and with teeth M2 for engaging with a spring M³ which
serves for steadying and supporting it. The plunger M is marked at the top with
divisions which can be read off by means of an index N and these divisions are
such that by the downward movement of the plunger M to the extent of one of the
teeth M', which is effected by a complete revolution of the counting wheel B, the
plunger is caused to move down to the extent of a hundred divisions.
When
the plunger M has reached a position such that the index N is opposite the last
division, one revolution of the counting-wheel B, which is equivalent to one
hundred oscillations of the lever D, is sufficient to cause the plunger M to force
down lever and disengage the bar o which is then drawn back by the spring q
(Figs. 1 and 2) in order to stop the corresponding knitting machine.
"
By the arrangement described it will be seen that each knitting machine can be
thrown out of operation after making any desired number of strokes within the
range of the apparatus.
In order to combine the stopping or disengaging apparatus with a "shogging"
device for the production of "shogged" goods (i.e. goods with zig-zag or Vandyke
designs), a third bar O (Figs. 13 to 16) inclusive is arranged in bearings O' and
is provided with two stops 02. A clip P arranged above the pawl k, or its
bearing, is furnished with a knob P¹, and is intended near the ends of the
reciprocation of the frame g, to strike against the projections 02, and thereby
operate the "shogging" device; when however the clip P is raised, it has no
action upon the stops 01 and 02. The bar O has two inclines which are
These
placed close together so as to leave a triangular space between them.
inclines serve to move a lever R up and down. This lever is pivoted at R' to the
machine frame and carries a pawl R2 which engages in a ratchet wheel S¹ attached
to the "shogging" wheel S; the pawl R2 is kept in gear with the teeth of the,
wheel S by a spring R³. The " shogging" wheel S is provided with a rim both
edges of which are furnished with teeth S² that are so arranged that the spaces S³
on one edge are opposite to the teeth on the other, and that the cross sections
of the rim through the teeth are of the same width wherever they are taken.
Against both sides of the rim there bear pins T which are provided with rollers
and are mounted on a lateral projection T¹ of one of the needle beds U.
the bar is moved by the clip P the lever R is first raised by one of the
inclines and then pressed down by the other incline to such a degree as to
rotate the shogging wheel S to the extent of a tooth, thus effecting the shifting
of the needle bed.
When
The clip P is constructed and arranged in such a manner that it also is raised
by means of the pawl k when the latter is lifted out by the bar o. By this means
the "shogging" device is disengaged at the same time as the driving apparatus.
In order to prevent over-rotation of the "shogging" wheel S, a brake block V
mounted on a spring V₁ bears against the periphery of the wheel S.
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. Apparatus for driving a number of knitting machines arranged in line and
for automatically throwing each of such machines out of action at predetermined
