page_text: We FREDERICK EMIL SCHLESINGER and JOSEPH HORROCKS both of Gotha in
the Empire of Germany Picker Manufacturers do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN LOOMS FOR WEAVING AND IN PICKERS FOR
LOOMS to be as follows:-

Our invention consists in the improved arrangements hereinafter described by
means of which the motion of the "going part" of a loom is utilized to actuate
the pickers by which the shuttles are driven and in the construction of the pickers
used in the said arrangements and hereinafter described.
The said arrangements consist essentially of mechanism carried by the "going
part" and connected with the pickers which mechanism is actuated by the engage-
ment of toothed wheels forming part thereof with racks supported by the frame or
other fixed part or parts of the loom which racks are connected with mechanism
by which they are caused to gear with or are ungeared from the said toothed
wheels as and when required.
We will describe the said arrangements with reference to the shuttle box on one
side of the loom the arrangement being similar on both sides.
.
We connect the picker at its acting side or end to one end of a coiled spring the
other end of which is secured to or near the inner end of the shuttle box and we
connect the picker at its opposite side or end to a strap or chain which passes over
a pulley at the outer end of the shuttle box and is connected at its other end to a
drum or pulley secured to a vertical shaft or spindle working in bearings in
a bracket affixed to the back of the shuttle box to which shaft are also secured a
ratchet or catch wheel and a toothed wheel which toothed wheel gears with
a pinion working in the said bracket or on a spindle affixed thereto..
To the frame of the loom or to a bracket affixed thereto we joint one end of a
rack in such a position relatively to the aforesaid pinion that by turning the said
rack slightly on its joint its teeth may be caused to gear with the pinion. The
said rack carries at its free end an antifriction roller which by means of a spring
acting on the said rack is caused to bear against the face of a toothed wheel
(hereinafter termed the cam wheel) working on a horizontal shaft affixed to and
projecting from the frame of the loom. The said cam wheel gears with a sinaller
toothed wheel keyed to the crank shaft of the loom and has a cam or tappet
formed on or affixed to the face against which the antifriction roller carried by the
rack bears the position of the said cam being such that by the revolution of the
cam wheel the cam is brought into contact with the roller on the rack which rack
is thus forced into gear with the aforesaid pinion.
To the back of the shuttle box we joint one end of a lever having a catch or
pawl on its underside which catch or pawl when the said lever is in its normal
position engages with the teeth of the aforesaid ratchet or catch wheel. The free
end of this lever lies in the path of motion of a pin on the cam wheel and when
by the revolution of the said wheel the said pin is brought in contact with the said
.

page_text: lever the latter is raised the catch on its underside being thereby disengaged from
the teeth of the said catch wheel. A spring restores the said lever to its normal
position when the pin has passed it.

The relative positions and the arrangement of the parts hereinbefore described
are such that on the "going part" of the loom moving backward the rack jointed
to the frame is caused to gear with the pinion carried by the bracket affixed to the
shuttle box the said pinion is thus caused to revolve and by its engagement or
gearing with the toothed wheel affixed to the vertical shaft or spindle carried by
the said bracket the catch wheel and the drum to which the strap or chain is
attached are also caused to revolve and the said strap is thus wound on its drum
the picker being thereby drawn towards the outer end of the shuttle box and the
spring in the shuttle box extended. This action continues until the picker has
been drawn nearly to the outer end of the shuttle box when by the revolution of
the cam wheel the cam on its face passes beyond the free end of the rack which is
then withdrawn by its spring from engagement with the pinion. The further
revolution of the cam wheel brings the pin on its face under the free end of the
catch lever and thus raises the catch thereon free of the teeth on the catch wheel
when the spring to which the picker is connected being released pulls the picker
to the opposite end of the shuttle box and drives the shuttle into the shuttle box
on the opposite side of the loom.
Mechanism similar to that herein before described is arranged on each side of the
loom and that on one side is arranged to work alternately with that on the
other side.

causes
Thus on starting the loom the first inward motion of the "going parti
the picker in one of the shuttle boxes (say that on the right of the loom) to be
drawn to the outer end of the box extending the spring therein and causes the
picker in the other shuttle box (that on the left of the loom) to be released thus
driving the shuttle from left to right and the second inward motion causes the
picker in the box on the left to be drawn back ready for action and that on the
right to be released thus driving the shuttle from right to left and so on.
The construction and arrangement of the picker are bereinafter described.
We form the picker of hide or other suitable material and mount it on a spindle
or in guides in the lower part of or below the shuttle box or we secure the picker
to a rod working in the lower part of the shuttle box and we form the picker so
that when thus mounted the acting part projects into the upper part of the shuttle
box and works in the path of motion of the shuttle. When the picker is to be
mounted on the spindle in the shuttle box or is to be secured to the rod working
therein we pierce the picker longitudinally to admit of its engagement with the
said spindle or with the said rod and when the picker is to be mounted in guides
in the shuttle box we-make the lower part of the picker of a form corresponding
with that of the said guides which in this case are so formed as to admit of the
picker moving only in a longitudinal direction in the shuttle box.
When we mount the picker on a spindle or in guides in the shuttle box we
connect the spring hereinbefore referred to and the strap or chain (which is con-
nected with the actuating mechanism herein before described) to the opposite ends.
of the said picker by means of hooks or eyes which we form on or in or secure to
the picker and when we secure the picker to a rod passing through its lower part
we connect the said actuating mechanism and the spring to opposite ends of the
said rod and mount or secure the spring in a slot or recess formed in the woodwork
of the lathe.

We FREDERICK EMIL SCHLESINGER and JOSEPH HORROCKS both of Gotha in
the Empire of Germany Picker Manufacturers do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN LOOMS FOR WEAVING AND IN PICKERS
FOR LOOMS" and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
Our invention consists in the improved arrangements hereinafter described by
means of which the motion of the "going part" of a loom is utilized to actuate the
pickers by which the shuttles are driven and in the construction of the pickers used
in the said arrangements and herein after described.
The said arrangements consist essentially of mechanism carried by the "going
part" and connected with the pickers which mechanism is actuated by the engage-
ment of toothed wheels forming part thereof with racks supported by the frame or
other fixed part or parts of the loom which racks are connected with mechanism by
which they are caused to gear with or are ungeared from the said toothed wheels as
and when required.
We will describe the said arrangement with reference to the shuttle box on one
side of the loom the arrangement being similar on both sides.
We connect the picker at its acting side or end to one end of a coiled spring the
other end of which is secured to or near the inner end of the shuttle box and we
connect the picker at its opposite side or end to a strap or chain which passes over
a pulley at the outer end of the shuttle box and is connected at its other end to a
drum or pulley secured to a vertical shaft or spindle working in bearings in a
bracket affixed to the back of the shuttle box to which shaft are also secured
a ratchet or catch wheel and a toothed wheel which toothed wheel gears with ȧ
pinion working in the said bracket or on a spindle affixed thereto.
i
To the frame of the loom or to a bracket affixed thereto we joint one end of a
rack in such a position relatively to the aforesaid pinion that by turning the said
rack slightly on its joint its teeth may be caused to gear with the pinion. The said
rack carries at its free end an antifriction roller which by means of a spring acting
on the said rack is caused to bear against the face of a toothed wheel (hereinafter
termed the cam wheel) working on a horizontal shaft affixed to and projecting from
the frame of the loom. The said cam wheel gears with a smaller toothed wheel
keyed to the crank shaft of the loom and has a cam or tappet formed on or affixed
to the face against which the antifriction roller carried by the rack bears the
position of the said cam being such that by the revolution of the cam wheel the cath
is brought into contact with the roller on the rack which rack is thus forced into
gear with the aforesaid pinion.
To the back of the shuttle box we joint one end of a lever having a catch or pawl
on its underside which catch or pawl when the said lever is in its normal position
engages with the teeth of the aforesaid ratchet or catch wheel. The free end of
this lever lies in the path of motion of a pin on the can wheel and when by the
revolution of the said wheel the said pin is brought in contact with the said lever
the latter is raised the catch on its underside, being thereby disengaged from the
teeth of the said catch wheel. A spring restores the said lever to its normal
position when the pin has passed it,

page_text: The relative positions and the arrangement of the parts herein before described
are such that on the "going part" of the loom moving backward the rack jointed
to the frame is caused to gear with the pinion carried by the bracket affixed to the
shuttle box. The said pinion is thus caused to revolve and by its engagement or
gearing with the toothed wheel affixed to the vertical shaft or spindle carried by
the said bracket the catch wheel and the drum to which the strap or chain is
attached are also caused to revolve and the said strap is thus wound on its drum
the picker being thereby drawn towards the outer end of the shuttle box and the
spring in the shuttle box extended. This action continues until the picker bas
been drawn nearly to the outer end of the shuttle box when by the revolution of
the cam wheel the cam on its face passes beyond the free end of the rack which is
then. withdrawn by its spring from engagement with the pinion. The further
revolution of the cam wheel brings the pin on its face under the free end of the
catch lever and thus raises the catch thereon free of the teeth. on the catch wheel
when the spring to which the picker is connected being released pulls the picker to
the opposite end of the shuttle box and drives the shuttle into the shuttle box on
the opposite side of the loom.
The construction and arrangement of the picker are hereinafter described.
We form the picker of hide or other suitable material and mount it on a spindle
or in guides in the lower part of or below the shuttle box or we secure the picker
to a rod working in the lower part of the shuttle box and we form the picker so
that when thus mounted the acting part projects into the upper part of the shuttle
box and works in the path of motion of the shuttle. When the picker is to be
mounted on the spindle in the shuttle box or is to be secured to the rod working
therein we pierce the picker longitudinally to admit of its engagement with the
said spindle or with the said rod and when the picker is to be mounted in guides in
the shuttle box we make the lower part of the picker of a form corresponding with
that of the said guides which in this case are so formed as to admit of the picker
moving only in a longitudinal direction in the shuttle box.
When we mount the picker on a spindle or in guides in the shuttle box we
connect the spring herein before referred to and the strap or chain (which is, con-
nected with the actuating mechanism hereinbefore described) to the opposite ends
of the said picker by means of hooks or eyes which we form on or in or secure to
the picker and when we secure the picker to a rod passing through its lower part
we connect the said actuating, mechanism and the spring to opposite ends of the
said rod and mount or secure the spring in a slot or recess formed in the woodwork
of the lathe.
Having now described the nature of our invention we will proceed to describe the
manner in which it is to be performed reference being had to the accompanying
drawings and to the letters and figures of reference marked thereon. The same
letters and figures of reference indicate the same parts in the several Figures of the
drawings.
Figure 1 of the accompanying drawings is a plan and Figure 2 is a side elevation
of a portion of a loom to which our invention is applied Figure 3 is a longitudinal
section of a portion of the shuttle box the section being taken on the line 1 Figure 1
Figure 4 is a detail hereinafter referred to and Figures 5 and 6 are elevations
taken at right angles to each other of a picker of one of the forms hereinbefore
described.

mounted on a spindle d secured in the lower part of the shuttle box the longi-
tudinal hole e¹ (see Figures 5 and 6) in the lower part of the said picker admitting
of its engagement with the said spindle f is the spring to which the picker is con-

nected. is the bracket affixed to the back of the shuttle box d h¹ is the vertical
spindle on which the drum h is secured and h² is the ratchet or catch,wheel and h³
the toothed wheel which are also secured to the said. spindle h¹. j is the toothed
wheel with which the said toothed wheel h³ gears. kis the rack jointed at k¹ to
the bracket k secured to the frame a of the loom which rack may be caused to
gear with the said toothed wheel ; or be disengaged therefrom by turning it slightly
on the joint k. k³ is the antifriction roller carried by the said rack is the toothed
cam wheel working on a pin * secured to the frame a of the loom and is the cam
on the face of the said wheel m is the toothed wheel mounted on the crank
shaft c and gearing with the said cam wheel is the spring by which the anti-
friction roller k³ is caused to bear against the cam 1. n is the catch lever (shown
separately in Figure 4) jointed at n¹ to the back of the shuttle box d n² (see
Figure 4) is the catch or tooth on the said lever which catch or tooth engages with
the teeth of the ratchet wheel h₁ is the pin on the cam wheel which pin when
the said wheel revolves acts on the lever n and causes the catch or tooth n³ thereon
to be disengaged from the teeth of the ratchet wheel h³. 13 is the spring by which
the tooth n on the said lever is held in gear with the teeth of the ratchet wheel h³
when the said lever is not acted on by the pin .
The action of the said mechanism is as follows:-On the going part of the
loom beginning to move backward (that is in the direction indicated by the
arrow in Figure 1) the cam on the cam wheel is in the position shown
in Figures 1 and 2 the rack k being thereby forced into gear with the toothed.
wheel. The continued backward motion of the going part therefore causes
the said toothed wheel to revolve and the said toothed wheel by its engage-
ment with the toothed wheel h³ causes the said toothed wheel h³ and the ratchet
or catch wheel 2 and the drum h also to revolve the strap g being thereby
wound on the said drum and the picker e drawn towards the outer end of the
shuttle box extending the spring f therein which action continues until the picker e
has been drawn nearly to the outer end of the shuttle box when the continued
revolution of the cam wheel causes the cam to be carried beyond the antifriction
roller on the end of the rack k and the spring withdraws the rack k from
engagement with the toothed wheel j. The spring f is however prevented from
contracting and the picker e is held at the outer end of the shuttle box d by the
engagement of the tooth or catch n on the lever n with the ratchet or catch
wheel until the further revolution of the cam wheel causes the pin 2 to bear
against the said lever n and raise its tooth n² from engagement with the teeth of
the ratchet wheel h² when the spring f contracts and draws the picker e to the
inner end of the shuttle box d and drives the shuttle therefrom into the shuttle box
on the opposite side of the loom.
"
Mechanism similar to that herein before described is arranged on each side of the
loom and that on one side is arranged to work alternately with that on the other side.
Thus on starting the loom the first inward motion of the "going part causes
the picker in one of the shuttle boxes (say that on the right of the loom) to be
drawn to the outer end of the box extending the spring therein and causes the
picker in the other shuttle box (that on the left of the loom) to be released thus
driving the shuttle from left to right and the second inward motion causes the
picker in the box on the left to be drawn back ready for action and that on the
right to be released thus driving the shuttle from right to left and so on.
Figures 7 and 8 of the accompanying drawings are elevations taken at right
angles to each other of a picker formed so as to admit of its engagement at the
lower part with a guide or guides in the lower part of the shuttle box as herein-
before described instead of with a spindle in the lower part of the shuttle box as
illustrated in Figures 1 and 2 of the accompanying drawings. Referring to the
said Figures 7 and 8 01 is the upper or acting part of the picker 'o' are projections

recess or recesses in the lower part of the shuttle box with which the said picker is
used and o³ o are hooks secured to the said lower part of the picker and projecting
therefrom by means of which hooks the spring fand band or strap g are connected
to the picker.
Figure 9 of the accompanying drawings is a longitudinal section of the upper
part of the going part of a loom showing the arrangement of the spring in the cases
where the pickers are secured to rods or bars as hereinbefore described instead of
working on spindles in the shuttle boxes as illustrated in Figures 1 and 2 of the
accompanying drawings.
Referring to the said Figure 9 p is the spring by which the shuttles are actuated
which spring is arranged in a recess b¹ formed in the underside of the lathe and
secured therein at or near its middle by a pin p¹. qq are the bars or rods to which
the pickers are secured which bars or rods work in holes formed in the ends of the
lathe and project into the said recess b' and are each connected at the inner end to
the spring p and at the outer end to one of the bands or straps gg. The pickers
are of the form illustrated in Figures 5 and 6 but are without the eyes e² es which
in this arrangement are not required.
Instead of connecting the picker to the drum by means of a band any other
suitable flexible connection such as a chain may be used.
Figure 10 of the accompanying drawings is a plan of the same parts of a loom
as those shown in Figure 1 to which is applied mechanism essentially similar to
that hereinbefore described with reference to Figures 1, 2 and 3 but somewhat
differently arranged. In the said Figure 10 all the parts with the exception of the
ratchet wheel the rack the bracket supporting the said rack the catch lever and the
pin which acts thereon are formed and arranged as described with reference to
the said Figures 1, 2 and 3 and are marked with corresponding letters and figures
of reference and consequently need no further description. The modified details
and their arrangement and action are hereinafter described..
In the said arrangement (Figure 10) the rack k is guided in its motion by a
bracket c³ secured to the frame a against which bracket the said rack bears near
its free end. ¹ is a ratchet wheel affixed to the spindle to which the wheel. j is
affixed and n³ is a lever jointed to the bracket i at n³ so as to be capable of motion
in a horizontal plane and having a tooth or catch formed on it which engages with
the teeth of the ratchet wheel j¹. 13 is a curved pin carried by the toothed
wheel and n is a spring by which the catch on the lever n³ is caused to
engage with the teeth of the said wheel when the said lever is not acted on
by the the said pin as hereinafter described. The action of this arrangement is
as follows:-
When the cam acts on the roller on the rack k any strain on the said rack
in an upward direction is prevented by its bearing against the bracket 5 and on
the said cam passing the said roller ³ and the said rack k being withdrawn by
the spring from engagement with the teeth of the wheel ; the engagement of
the tooth or catch on the lever n³ with the ratchet wheel j¹ prevents the spring f
in the shuttle box d from contracting until the said wheel is liberated by the
action on the said lever n³ of the curved pin 3 which by the rotation of the
toothed wheel is carried past the said lever n³ and pushes it horizontally away
from the said ratchet wheel ¹ and keeps the catch on the said lever out of
engagement with the teeth of the said ratchet wheel until by the continued
rotation of the toothed wheel the said pin is carried beyond the lever n³ when
the spring n restores the said lever to the position shown in the drawing the
tooth or catch thereon then again engaging with the teeth of the said ratchet
wheel.
Instead of arranging the rack and gearing as herein before described the toothed
wheel which gears with the rack and the ratchet wheel may be mounted in vertical
planes. In this case the rack is so arranged as to be raised by the cam on the cam
wheel in order to engage the said rack with the toothed wheel..

ris the toothed wheel with which the rack k gears and s is the ratchet wheel
which wheels and 8 are both secured to a spindle t. uv are bevil wheels by which
motion is communicated from the said spindle to the drum h by the toothed
wheels wand the wheel x being affixed to the spindle h¹ to which the said
drum h is also affixed. The rack is caused to gear with the wheel r by the
cam which raises the said rack. When by the rotation of the cam wheel the
said cam is carried from under the free end of the said rack the latter falls clear
of the toothed wheel and rests on the bracket 6. The catch lever n is raised
and the catch thereon disengaged from the ratchet wheels by the action of the
pin as herein before described with reference to Figures 1 and 2 of the accom-
panying drawings.
The pickers used in the several arrangements herein before described may be
formed of hide or other suitable material.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we wish it to be
understood that we do not limit ourselves to the precise details described as they
may be varied without departing from the nature of our invention but We declare
that what We claim as our said invention of "Improvements in looms for weaving
and in pickers for looms" is
First Connecting the pickers at their inner ends to a spring or springs and at
their outer ends to drums connected with toothed wheels carried by the going part
and caused to revolve by the engagement of the said toothed wheels with racks
supported by the frame or other fixed part or parts of the loom the said racks being
connected with mechanism by which they are caused to gear with or are ungeared
from the said toothed wheels as and when required and the said drums or the said
toothed wheels being connected with mechanism by which their rotation is
prevented or permitted as and when required.
Secondly-The general combination or arrangement of parts constituting the
mechanism herein before described with reference to and illustrated in Figures 1, 2
and 3 of the accompanying drawings for actuating the pickers in looms sub-
stantially as described.
Thirdly The modified arrangement of mechanism herein before described with
reference to and illustrated in Figure 10 of the accompanying drawings for
actuating the pickers in looms substantially as described..
Fourthly A picker the acting part of which is formed at the upper part and the
lower part of which has a hole formed in it longitudinally to admit of the
engagement of the picker with a spindle in the lower part of the shuttle box or
with a rod by which the actuating mechanism is connected to the picker sub-
stantially as herein before described and illustrated in Figures 5 and 6 of the
accompanying drawings.
