We JOSEPH HORROCKS and EDWIN HORROCKS both of Park Road Bradford in
the County of York Picker Manufacturers do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN MECHANISM OR ARRANGEMENTS FOR ACTUATING
THE PICKERS IN LOOMS to be as follows:-
"
Our invention consists first of the improvements hereinafter described on the
invention for which Letters Patent dated the fifth day of September 1884 N° 12048
were granted to Frederick Emil Schlesinger and Joseph Horrocks the latter being
one of the present applicants.
According to our said improvements we connect each of the pickers to a separate
bar which bars we mount in the lathe as described in the aforesaid specifications
and we use two picker levers which we mount in the going part and we joint the
inner ends of the said bars to the upper ends of the picker levers and we actuate
the said levers by means of a tappet or tappets mounted on the ordinary tappet
shaft or on a rotatory shaft geared thereto which tappet or tappets acts or act on
antifriction rollers mounted on arms carried by the picker levers or on arms carried
by shafts to which are affixed other arms which act on the said picker levers. The
rotation of the tappet shaft causes the tappet or tappets thereon to act on the
antifriction rollers alternately. The picker levers and the pickers connected to them
are thus actuated alternately and independently. The return motion of the picker
levers after the tappet or tappets has or have passed the rollers is effected by a
spring or springs.
The range of motion of the said levers is limited by stops or buffers of suitable
material.
In some cases we secure guides to the "going part" in which guides the picker
levers work.
Our invention consists further in making the tappet shells in two parts and
securing the parts together on the boss on the tappet shaft by means of bolts.
This construction of the said tappet shells admits of their connection with the
tappet shaft being effected without removing the latter from its bearings in the
loom.

We JOSEPH HORROCKS and EDWIN HORROCKS both of Park Road Bradford in
the County of York Picker Manufacturers 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:—
Our invention consists first of the improvements bereinafter described on the
invention for which Letters Patent dated the fifth day of September 1884 N° 12048
were granted to Frederick Emil Schlesinger and Joseph Horrocks the latter being
one of the present applicants.
According to our said invention we connect each of the pickers to a separate bar
which bars we mount in the lathe as described in the aforesaid specifications and
we use two picker levers which we mount in the going part and we joint the inner
ends of the said bars to the upper ends of the picker levers and we actuate the
said levers by means of a pair of tappets mounted on the ordinary tappet shaft
and acting on antifriction rollers mounted on arms carried by rocking shafts to
which are affixed other arms which are engaged with the picker levers or by
means of one tappet which is mounted on a rotatory shaft geared to the tappet
shaft and acts on the said antifriction rollers or on antifriction rollers mounted
on arms carried by the picker levers. In each of the said arrangements the rotation
of the tappet shaft causes the tappet or tappets thereon to act on the antifriction
rollers alternately the picker levers and the pickers connected to them being thus
actuated alternately and independently. The return motion of the picker levers
after the tappet or tappets has or have passed the rollers is effected by a spring
or springs.
The range of motion of the said levers is limited by stops or buffers of suitable
material.
In some cases we secure guides to the going part in which guides the picker
levers work.
The arrangement in which motion is communicated to the picker levers from the
tappet shaft by the action of a pair of tappets on antifriction rollers mounted on
arms carried by rocking shafts furnished with other arms which act on the picker
levers is illustrated in Figures 1 and 2 of the accompanying Drawings Figure 1
being a front elevation of parts of a loom showing our improvements applied
thereto and Figure 2 a transverse vertical section taken on the line 1 Figure 1 In
the said Figures and in all the Figures of the Drawings hereinafter referred to the
same letters and figures of reference indicate the same parts.
A A are portions of the frame of the loom B is the lathe b¹, 6' are the parts by
which the said lathe and the parts in connection therewith are supported the whole
being ordinarily termed the "going part" CC are the pickers D D are the picker
levers and c¹, c¹ are the rods by which the said pickers are respectively connected to
the said picker levers. The said rods c', c¹ work in a recess 6* formed longitudinally
in the underside of the lathe B and are connected to the levers D D as shown in
Figures 3 and 4 of the accompanying Drawings. Figure 3 being a side view and
Figure 4 an edge view of the connected ends of the said parts showing the details
of the connection which are hereinafter described. c is a pin the end of which is
screwed and passed through a hole in the end of the rod c¹ and secured by means

page_text: of a screw nut c³. The said pin passes through a slot in the lever D and
carries a roller c¹ which works in the said slot and the said pin has formed on it
a head c which keeps the said roller in place and prevents accidental disengage-
ment of the said rod and lever. The picker levers D D are supported by and work
on centres d³, d³ carried by brackets d', d³ secured to the uprights b₁, b¹ of the
going part. E E are the tappets e¹ is the tappet shaft which works in bearings e³, eª
supported by the frame of the loom as usual. F F are the rocking shafts f¹, f' are
the antifriction rollers on which the tappets act ƒ³, få are the arms on which the
said antifriction rollers are mounted and f³, f are the other arms on the said
rocking shafts which arms are engaged with the said levers by means of pins f*, f
affixed to the said arms near their outer ends. In order to admit of varation of
the path of motion and of the throw or extent of traverse of the levers D D each
of the said arms f³, f³ is connected to its shaft as hereinafter described. Near
the forward end of each of the said shafts F F a disc f' is secured and the end of
the shaft projecting beyond the said disc is reduced and on the reduced end another
disc f is placed. The said two discs f³, fe have teeth or serrations formed on
their meeting faces (see Figure 2) by which teeth the said discs are engaged together
and on the outer face of the disc f a depression or channel is formed in which the
arm fengages. A slot is formed longitudinally in the said arm f' through which
slot the end of the shaft F passes and the said disc f and arm ƒ³ are secured by
means of a nut f' which is screwed on to the projecting end of the said shaft.
When it is required to adjust or vary the path of motion of the said levers D D
the nut is slackened sufficiently to admit of the disc f being disengaged from
the disc f the said disc f* is then partially turned or rotated on the shaft to
which it is connected and reengaged with the disc f and secured by screwing up
the nut f. When the throw of the levers D D is required to be adjusted or
varied the nut f7 is slackened sufficiently to admit of the arm f³ being slidden
longitudinally in the depression in the face of the disc f the said arm is then
slidden in one or other direction to the necessary extent and secured as adjusted
by means of the nut f. g', g' are springs which restore the parts of the mechanism
herein before described to the positions shown in the drawings when the tappets
cease to act on the rollers f¹, f¹.
The action of the arrangement herein before described is as follows:—
As the tappet shaft e¹ rotates the mechanism on the two sides of the loom is
actuated alternately by the tappets E E the rotation of the said tappets causing
the said mechanism to be suddenly thrown into the position indicated in dotted
lines on the left hand side of Figure 1 whereby the shuttle is driven as required from
one shuttle box to the other. On the tappets ceasing to act on the said mechanism
the springs g¹, g¹ restore the parts to their original positions.
The arrangement in which motion is communicated to both picker levers from
the tappet shaft by means of one tappet which is mounted on a rotatory shaft
geared to the tappet shaft and acts on rollers carried by the rocking shafts con-
nected to the picker levers is illustrated in Figures 5 and 6 of the accompanying
Drawings Figure being an elevation of parts of a loom (corresponding to those
marked A. B¹ Ce¹ in Figure 1 hereinbefore described) showing the said arrange-
ment applied thereto and Figure 6 being a plan of parts of the said mechanism
and parts of the frame of the loom.
In this arrangement the picker levers D D are mounted and connected to the picker
rods c¹, cl as herein before described with reference to Figures 1. 2. 3 and 4 and the
rocking shafts FF carrying the anti friction rollers f¹, f¹ and arms f³, fs are mounted
and arranged relatively to the said levers in a manner substantially the same as that
described with reference to the said Figures 1 and 2. The other parts of the said
arrangement are hereinafter described. E¹ is the tappet which acts on the antifriction
rollers f, H is the rotatory shaft to which the said tappet is secured which
shaft is mounted vertically and works in bearings carried by supports h¹, h¹ secured
to the lower part of the frame of the loom and is geared to the tappet shaft
by means of bevil wheels h², e. The picker levers D D are in this arrangement

page_text: connected to the pins f*, f* on the arms f³, f' by straps d*, d* and are connected
together by the spring g¹.
The action of this arrangement is as follows:-
Rotatory motion is communicated from the shaft e¹ to the shaft H carrying the
tappet E which tappet in rotating acts alternately on the two antifriction
rollers f¹, f¹ thus causing the mechanism on each side to be alternately thrown
into the position indicated in dotted lines on the left band side of Figure 5 thereby
actuating the pickers as required. The spring g¹ restores the parts to their original
position when the tappet El ceases to act on the rollers f¹, f¹.
The arrangement in which motion is communicated from the tappet shaft to the
picker levers by the action on antifriction rollers carried thereby of a single tappet
mounted on a rotatory shaft geared to the tappet shaft is illustrated in Figures 7
and 8 of the accompanying Drawings which Figures correspond with Figures 5
and 6 herein before referred to except in respect of the mounting of the tappet E¹
and of the picker levers D D and the arrangement for communicating motion from
the former to the latter.
In this arrangement the picker levers D D are mounted in brackets b², 6*
carried by the bottom bar 63 of the going part and the shaft H which carries the
tappet E¹ is mounted horizontally in bearings h³, h³ supported by the lower part
of the frame of the loom and is geared to the tappet shaft e¹ by means of the bevil
wheels es, has in the arrangement illustrated in Figures 5 and 6. The said
levers D D work in guides carried by a bar I secured to the uprights 6', 6' of the
going part and the said levers are respectively connected at their upper ends to the
pickers C by means of the rods o¹, c¹ as shown in the said Figure 7 the lever on
the right hand side being connected to the picker on the left hand side and vice
versa. d', d' are the antifriction rollers on which the tappet E¹ acts which rollers
are mounted on pins or arms d³, d³ secured to the picker levers D D. The rotation
of the tappet E causes the said levers to be alternately thrown outwards as
indicated in dotted lines on the right hand side of Figure 7 the two pickers being
thus alternately actuated as required. The spring g₁ restores the said levers to
their original positions when the picker ceases to act on them.
In each of the arrangements hereinbefore described motion is communicated to
the tappet shaft from the main shaft as usual
The parts of the loom not shown in the accompanying Drawings are of the
ordinary construction.
Either of the arrangements of mechanism hereinbefore described may be readily
applied to existing looms.
Our invention consists further in making the tappet shells in two parts and
securing the parts together on the boss on the tappet shaft by means of bolts.
This construction of the said tappet shells admits of their connection with the
tappet shaft being effected without removing the latter from its bearings in
the loom.
Figure 9 of the accompanying Drawings is an edge view Figures 10 and 11 are
elevations of opposite sides of a tappet constructed according to our invention and
connected to the tappet shaft. Figure 12 is a section of the tappet alone taken on
the line 2 Figure 10. Figures 13 and 14 are views of opposite sides of one of the
two parts of the tappet shell shown separately Figures 15, 16 and 17 are edge
views of the said part and Figure 18 is a section thereof taken on the line 3
Figure 13. Figure 19 is a face view of the other of the said parts shown separately
Figures 20 and 21 are edge views thereof and Figure 22 is a section thereof taken
on the line 3 Figure 19.
JK are the said two parts of the shell or body of the tappet L is the nose of
the tappet is the tappet shaft and M is the boss keyed on the said shaft to
arms m¹, m³ on which boss the tappet is secured by bolts m³, m³. In the part J of
the tappet shell holes ¹, j³ (see Figures 13 and 14) are formed and on the part K
of the tappet shell flanges k, k are formed having holes k¹, k* (see Figure 19) in
them the said holes, and. k¹, k³ being formed. in such positions that when the

page_text: two parts of the shell are put together the holes j, j coincide respectively with the
holes k, k and with holes formed in the arms m¹, m' on the boss M and the said
two parts of the tappet shell are secured together and to the tappet shaft by
passing the screw bolts m², m³ through the said coincident holes and screwing nuts
on the screwed ends of the said bolts. The nose L of the tappet is formed
separately from the shell and secured thereto by a screw bolt and nut as usual
The construction hereinbefore described of the tappet shell admits of the connection
of the tappet to and its disconnection from the boss on the tappet shaft without
removal of the latter from its bearings in the loom which is necessary in connecting
and disconnecting tappets formed in one piece as usual. Although we prefer to
connect the two parts of the tappet shell together by means of the same bolts
which connect the tappet to the boss on the tappet shaft we do not limit ourselves
to that arrangement as the two parts of the tappet shell may be connected together
independently of the connection of the tappet to the said boss.
Tappets constructed as herein before described are applicable for use in looms in
which the pickers are actuated by means of the ordinary mechanism or by means
of our improved mechanism herein before described or by other means requiring the
use of tappets.
Having now particularly described and ascertained the nature of this 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 hereinbefore described as they
may be varied without departing from the nature of our said Invention but we
declare that we claim as our said invention of "Improvements in mechanism or
arrangements for actuating the pickers in looms"
First. Mechanism for working the pickers in looms consisting essentially of a
pair of levers mounted in the going part and each connected to one of the pickers
and actuated independently the required motion being communicated to the said
levers from the tappet shaft through intermediate mechanism substantially as
hereinbefore described.
Secondly. The arrangement hereinbefore described with reference to and illus-
trated in Figures 1 and 2 of the accompanying drawings for actuating the picker
levers.
Thirdly. The arrangement herein before described with reference to and illus-
trated in Figures 5 and 6 of the accompanying Drawings for actuating the picker
levers.
Fourthly. The arrangement herein before described with reference to and illus-
trated in Figures 7 and 8 of the accompanying drawings for actuating the picker
levers.
Fifthly. A tappet for looms the shell or body of which is formed of two parts
capable of being secured together on the boss on the tappet shaft whereby the
removal of the said shaft from its bearings in order to connect the tappet to the
shaft and to disconnect the tappet from the shaft is rendered unnecessary.
Sixthly. The improved tappet for looms herein before described and illustrated
in Figures 9, 10, 11 and 12 of the accompanying drawings that is to say a tappet
the shell or body of which is formed in two parts capable of being secured together
and to the boss on the tappet shaft substantially as described.
