Improvements in. or relating to Change Motions for Shuttle Boxes.
I, GUSTAV FALKE, of Oberlangenbielau, in the Empire of Germany, Manager
of Weaving Mills, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in change motions for operating quadruple
shuttle boxes described in the Specification of Letters Patent No. 7163 of 1894 and
it has for its object additions to or extensions of such change motion, for the purpose
of adapting such arrangement for giving the necessary movements required for
operating a sextuple shuttle box.
A shaft carried in bearings secured to the framing is reciprocated or rocked
preferably through an angular space of half a revolution by means of a toothed
wheel or pinion secured thereto, which wheel engages with an oscillating toothed
sector or quadrant of similar construction to that described in Letters Patent
hereinbefore referred to.
Secured to the shaft are three discs each provided with a corresponding notch or
recess in its periphery which notches are at one extremity of the rocking motion of
the shaft vertically above it.
'
At the side of each fixed disc is a loose or driving disc provided with a slot or
enlarged hole so as to be independent of the shaft, they are held in their normal
position or concentric with the shaft by three horizontal selector needles arranged
on the underside of the discs and which needles are provided with projections which
engage with studs on the respective discs.
The card cylinder is connected by a draw bar, pivotted arm, and connecting rod,
to the oscillating toothed sector so that by the movement of the latter the card
cylinder is moved up to the selector needles and if one of the selector needles is
moved owing to the absence of a perforation in the card, the projection on such
selector is moved out of engagement with the stud on its corresponding disc and it
is allowed to fall.
When a driving disc falls a stud on its upper side enters into the notch or recess
on its corresponding fixed disc and on the return swing of the toothed sector the
loose or driving disc is carried along with the fixed disc.
Mounted loosely on the shaft at the side of each loose or driving disc are inter-
mediate wheels which are permanently engaged with their corresponding driving
discs by means of slots in the one engaging with studs in the other, the movement
of each driving disc is therefore communicated to its corresponding wheel.
The movement of one of the intermediate wheels is communicated to an eccentric
sheave which is secured thereto, mounted on this sheave is an eccentric ring on
which is the eccentric strap. The eccentric ring is connected to the second inter-
mediate wheel, by a stud on the one engaging with a slot in the other and the
eccentric strap is connected by a rod to a compound lever arrangement hereinafter
described.
Secured to the third intermediate wheel is an eccentric sheave the strap of which
is also connected by an independent rod to the compound lever arrangement.
The compound eccentric with its operating mechanism comprises the quadruple
shuttle box motion described in the Specification of Letters Patent referred to, and
the strap is connected by a rod to a point between the two ends of a main lever one
end of which is pivotted to a fixed point.

page_text: Pivotted at the free end of this lever is a second supplementary lever the latter
being pivotted midway between its two ends. The inner end of this lever is
connected by a rod to the eccentric which is operated by the third intermediate
wheel, and its outer end is connected by a connecting rod to the shuttle box.
By this arrangement the shuttle box may be raised one, two, or more compart-
ments by the independent or cumulative action of the eccentrics as required.
In a modification the compound eccentric may be connected to the supplementary
lever and the other to the main lever.

Improvements in or relating to Change Motions for Shuttle Boxes.
I, GUSTAV FALKE, of Oberlangenbielau, in the Empire of Germany, Manager
of Weaving Mills, 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 improvements in change motions for operating quadruple
shuttle boxes described in the Specification of Letters Patent No. 7163 of 1894 and
it has for its object additions to or extensions of such change motion, for the purpose
of adapting such arrangement for giving the necessary movements required for
operating a sextuple shuttle box.
The invention will be best understood by reference to the accompanying drawings
in which :-
Figure 1 is a section of the apparatus taken on the line 1-1 of Figure 2 which
is a section on the line 2-2 of Figure 1.
Figure 3 is a section on the line 3-3 of Figure 1.
Figure 4 is a plan.

Figure 5 is a diagrammatic view of the compound eccentric mechanism and
Figure 6 is a diagrammatic view of a modified arrangement of the compound
eccentric mechanism.
A shaft carried in bearings secured to the framing is reciprocated or rocked
preferably through an angular space of half a revolution by means of a toothed
wheel or pinion e secured thereto, which wheel engages with an oscillating toothed
sector or quadrant of similar construction to that described in Letters Patent
herein before referred to.
Secured to the shaft are three discs e¹ e²e each provided with a corresponding
notch or recess e Fig. 2 in its periphery which notches are at one extremity of the
rocking motion of the shaft vertically above it.

}
At the side of each fixed disc e e e is a loose or driving disc f¹ ƒ³ ƒ³·
respectively, provided with a slot or enlarged hole so as to be independent of the..
shaft, they are held in their normal position or concentric with the shaft by three
horizontal selector needles p¹ p³ p³ arranged on the underside of the discs and which
needles are provided with projections p which engage with studs fº Fig. 1 on the
respective discs.
'
The card cylinder or prism o is connected by a draw bar ³, pivoted arm r¹, and
connecting rod r, to the oscillating toothed sector / so that by the movement of the
latter the card cylinder is moved up to the selector needles p¹ p² p³ and if one of
the selector needles is moved owing to the absence of a perforation in the card,
the projection pt on such selector is moved out of engagement with the stud f° on
its corresponding disc f¹ for f³ which is thus allowed to fall.
When a driving disc f¹ for f' falls a stud f* on its upper side enters into the

page_text: notch or recess * of the corresponding fixed disc el e³ ³ and on the return swing of
the toothed sector h this particular loose or driving disc is carried along with the
fixed disc with which it is then engaged.
Mounted loosely on the shaft i at the side of the loose or driving discs f¹ ƒª ƒ³
are intermediate wheels d' dd which are permanently engaged with their corre-
sponding driving discs f¹ƒ ƒ by means of slots d* in the one engaging with studs f
in the other, the movement of each driving disc is therefore communicated to its
corresponding wheel.
The movement of the intermediate wheel is communicated to un eccentric
sheave i which is secured thereto, mounted on this sheave is an eccentric ring k on
which is the eccentric strap. The eccentric ring k is connected to the inter-
mediate wheel d¹, by a stud k¹ on the former engaging with a slot in the latter or
vice versa and the eccentric strap is connected by a rod m to a compound lever
arrangement hereinafter described.
Secured to the intermediate wheel d³ is an eccentric sheave the strap of which
is also connected by an independent rod n to the compound lever arrangement.
The compound eccentric ik with its operating mechanism comprises the
quadruple shuttle box motion described in the Specification of Letters Patent
referred to, and the rod m thereof is connected to a point between the two ends
of a main lever s¹s the end s¹ of which is pivoted to a fixed point.
Pivoted to the free end of this lever is a second or supplementary lever t¹²
the latter being pivoted at about midway between its two ends. The end t' of this
lever is connected by the rod n to the eccentric which is operated by the inter-
mediate wheel d³, and its outer end is connected by a connecting rod v to the
shuttle box.
By this arrangement the shuttle box may be raised one, two, or more
compartiments by the independent or cumulative action of the eccentrics i klas
required.
In a modification as shown diagrammatically in Fig. 6 the compound eccentric i k
may be connected to the supplementary lever w¹ w³ and the other eccentric 1, to the
main lever u¹ u³ u³.
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. A change-motion for a sextuple shuttle-box wherein three operative parts i kl
of the throw-mechanism are actuated the manner described in Patent No. 7163 '94
and act upon a lever-combination in such manner that the movements of the
operative parts of the throw mechanism are cumulative.
2. The combination and arrangement of parts constituting the complete change
motion for shuttle boxes substantially as described and illustrated in the accom-
panying drawings.
