Year: 1866

page_text: LETTERS PATENT to William Rossetter, of Accrington, in the County
of Lancaster, for the Invention of "IMPROVEMENTS IN LOOMS FOR
WEAVING"
Sealed the 9th April 1867, and dated the 13th October 1866.
PROVISIONAL SPECIFICATION left by the said William Rossetter at the
Office of the Cominissioners of. Patents, "with his Petition, on the
13th October 1866.
I WILLIAM ROSSETIER, of Accrington, in the County of Lancaster, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN LOOMS
FOR WEAVING," to be as follows:-
This invention. consists. in various improvements upon an Invention for
which Letters Patent were granted to John Bullough and myself, of
Accrington, in the County of Lancaster, entitled, "Improvements in Looms
for Weaving," and dated January 1st, 1866, No. 1..
In the Specification of that Invention we stated that our Invention consists
of improved apparatiis.and.mechanism for changing self-actingly the shuttle
in which the weft has broken or is used up for another shuttle with the weft
ready for weaving.without stopping the loom, and when the weft of this second
shuttle becomes brcken or absent to replace it by another shuttle with new
weft, and so on, using as many shuttles as may be found-convenient or
desirable, thus requiring the operator to attend to the loom only after two,
;

page_text: three, or more shuttles have spent or broken their weft, instead of after a
single shuttle has failed to give weft as heretofore in the generality of looms.
To accomplish this object we stated that at each end of the slay or batten we
have a horizontal or slightly inclined shuttle box placed in slides or guides,
and that we employ two weft motions which are worked alternately by two
tappets on the tappet shaft, and drive the loom by friction pulleys instead of
by the common fast and loose pulleys heretofore in general use, and that the
shuttle boxes were made to hold two, three, or more shuttles, as found to be
advantageous.
The object of my present Invention is to change self-actingly the shuttle in
which the weft is broken or absent for another shuttle with the weft ready for
weaving without stopping the loom by means of certain arrangements of
mechanism and apparatus of greater simplicity and efficiency than those
hitherto employed.
One part of my present improvements consists in dispensing with the
enlarged shuttle boxes containing several shuttles at the ends of the slays of
the looms, and employ for each loom only one shuttle at the time working to
and fro on the slay the same as in an ordinary loom, thereby preventing extra
momentum which would be the effect when using a number of shuttles and a
box to receive them working backwards and forwards at high speeds. To the
ordinary weft-fork holder I connect a lever for giving motion to a rod or tube
extending across the loom underneath the breast beam, when on account of
the breakage or absence of weft the ordinary hammer catches the hook of the
weft fork. At one or both sides of the loom I fix a bracket having a slide and
stud carrying a compound lever with two or more arms, and to one or both
ends of the rod or tube underneath the breast beam is fixed a lever for raising
the slide, stud,and compound lever when there is breakage orabsence of weft,
and bringing one of the arms into position to be acted upon by a tappet on
the tappet shaft or a projection on the slay, and give vibrating motion to the
compound lever for enabling one arm of the compound lever or a lever at the
back of the slay to move a hinged shutter or slide at one end of the slay for
allowing the empty to fall through a space in the slay into a receptacle, and
at the same time allow another arm to bring forward a fresh shuttle with
weft ready for picking; and another mode of preventing an empty shuttle
from passing to the opposite box is to have an additional lever on the rod or
tube below the breast beam working a projection or arım in the slay, and
pushing the shuttle into a receiver.
Another part of my improvements consists in the employment of a table or
creeper on the breast beam or loom side at the front of the slay for holding

page_text: one or more shuttles with weft ready for being self-actingly placed on the
end of the slay when breakage or absence of weft takes place. This table
or creeper is placed in such a position that the weaver can see when the
shuttle or shuttles are about to be needed, the shuttles remaining stationary
until absence of weft is indicated, which arrangement enables fresh shuttles to
be supplied to the table or creeper with great facility and dispatch, and by
causing the shuttle with absent or broken weft to fall out at one end of the
slay, and supplying a fresh shuttle at the other end of the slay, more time is
allowed than if both operations took place at one end of the slay. One form
of the table or creeper consists of tapes, bands of steel or chains with narrow
projections on them for keeping the shuttles apart previous to being put in
the shuttle box on the slay.
In another arrangement I employ a plain table the length of the shuttles,
having a rack or toothed wheel pitched to correspond with the width of the
shuttles, so that when a shuttle is removed from the table to the shuttle box
the rack or wheel makes a sliding or revolving movement in order to bring
forward the next shuttle ready for the next operation, and at the front of the
tables or creepers there are projections which fit corresponding recesses in the
slay for forming a bridge or continuous surface for the shuttles to travel on
from the table or creeper to the shuttle box on the slay.
Another of my improvements consists in making a dead pick at that side
of the loom where absence of weft is indicated, and causing the bottom of the
shuttle box to spring up and throw the empty shuttle out of, the box into a
receiver; and when this method is applied to an over-pick loom the fly or
picker spindle must be raised to allow the shuttle to be passed into the receiver.
In under-pick looms I modify this arrangement by placing a hinged plate in
the shuttle box, there being a guard on the plate for guiding the shuttle, and
when the shuttle is empty, and revolving motion given to the hinged plate,
the shuttle falls into a receiver. I also employ a similar hinged plate on the
table or creeper which holds the full shuttles, so that when motion is given to
the hinged plate a shuttle will be detached from the table or creeper and
pushed into the box with weft ready for picking.
Another improvement consists in the employment of a revolving cutter or
knife which is brought into action at the required time for cutting away the
ends of weft from the spring holder or peg, which holds each thread of weft
until the shuttle has gone across and made a pick, and thereby preventing the
ends of weft from coming in contact with the weft fork.

by the said William Rossetter in the Great Seal Patent Office, on the
13th April 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
ROSSETTER, of Accrington, in the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of October, in the year of our
Lord One thousand eight hundred and sixty-six, in the thirtieth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said William Rossetter, Her special license that I, the said William
Rossetter, my executors, administrators, and assigns, or such others as I,
the said William Rossetter, my executors, administrators, and assigns, should
at any time agree with, and no others, from time to time and at all times
.thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN LOOMS FOR WEAVING," upon the condition (amongst
others) that I, the said William Rossetter, my executors or administrators,
by an instrument in writing under my, or their, or one of their hands
and seals, should particularly describe and ascertain the nature of the
said Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said William Rossetter, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, that is to say :-
This Invention consists in various improvements upon an Invention for
which Letters Patent were granted to John Bullough and myself entitled
"Improvements in Looms for Weaving, and bearing date the First day of
January, in the year of our Lord One thousand eight hundred and sixty-six,
No. 1. In the Specification of that Invention we stated that "Our Invention
"consists of improved apparatus and mechanism for changing self-actingly the
"shuttle in which the weft is broken or is used up for another shuttle with the
"weft ready for weaving without stopping the loom, and when the weft of this
"second shuttle becomes broken or absent to replace it by another shuttle with
"new weft, and so on, using as many shuttles as may be found convenient or

page_text: ""
"desirable, thus requiring the operator to attend to the loom only after two,
"three, or more shuttles have spent or broken their weft instead of after a
"single shuttle has failed to give weft as heretofore in the generality of looms.'
To accomplish this object we stated that at each end of the slay or batten
we have a horizontal or slightly inclined shuttle box placed in slides or
guides, and that we employ two weft motions which are worked alternately
by two tappets on the tappet shaft, and drive the loom by friction pulleys
instead of by the common fast and loose pulleys heretofore in general use,
and that the shuttle boxes were made to hold two, three, or more shuttles
as found to be advantageous.
The object of my present Invention is to change self-actingly the shuttle
in which the weft is broken or absent for another shuttle with the weft ready
for weaving without stopping the loom. by means of certain arrangements of
mechanism and apparatus of greater simplicity and efficiency than those
hitherto employed.
One part of my present improvements consists in dispensing with the
enlarged sbuttle boxes containing several shuttles at the ends of the slays of
the loons, and employ for each loom only one shuttle at the time working to
and fro on the slay, the same as in an ordinary loom, thereby preventing
extra momentum which would be the effect when using a number of shuttles
and a box to receive them working backwards and forwards at high speeds.
To the ordinary weft fork holder I connect a lever for giving motion to a rod
or tube extending across the loom underneath the breast beam when on
account of the breakage or absence of weft the ordinary sector hammer
catches the hook of the weft fork. At one or both sides of the loom I fix a
bracket having a slide and stud or a shaft carrying a compound lever with
two or more arms, and to one or both ends of the rod or tube underneath the
breast beam is fixed a lever for calling into action the compound lever when
there is breakage or absence of weft, and bringing one of the arms into
position to be acted upon by a tappet on the tappet shaft or a projection on
the slay, and give vibrating motion to the compound lever for enabling one
arm of the compound lever or a lever at the back of the slay to move a
hinged shutter or slide at one end of the slay for allowing the empty shuttle
to fall through a space in the stay into a receptacle, and at the same time
allow another arm to bring forward a fresh shuttle with weft ready for
picking; and another mode of preventing an empty shuttle from passing to
the opposite box is to have an additional lever on the rod or tube below the
breast beam working a projection or arm in the slay and pushing the shuttle
into a receiver.
...1..

page_text: Another part of my improvements consists in the employment of a creeper
or plain table and box on the breast beam or loom side opposite to the frout
of the slay for holding a number of shuttles with weft ready for being self-
actingly placed on the end of the slay when breakage or absence of weft takes
place. This creeper or table is placed in such a position that the weaver can
see when the shuttle or shuttles are about to be needed,the shuttles remaining
stationary until absence of weft is indicated, which arrangement enables fresh
shuttles to be supplied to the creeper or table with greater facility and
dispatch than when moveable shuttle boxes are used, and by causing the
shuttle with absent or broken weft to fall out at one end of the slay, and
supplying a fresh shuttle at the other end of the slay more time is allowed
than if both operations took place at one end of the slay. One form of
creeper consists of tapes, bands of steel, or chains, with narrow projections on
them for keeping the shuttles apart previous to being put in the shuttle box
on the slay, and in one arrangement of creeper I employ a rack or toothed
wheel or lever having a motion corresponding with the width of the shuttles,
so that when the rack makes a sliding movement, or the wheel or lever a
revolving movement, the foremost shuttle on the creeper is shifted to the
shuttle box and the next shuttle brought forward ready for the next operation,
and at the front of each table or frame of the creeper there are projections
which fit corresponding recesses in the slay for forming a bridge or continuous
surface for the shuttles to travel on from the creeper or table to the shuttle
box on the slay; or I form recesses in and projections on both the slay and
the table or frame of the creeper; or I form the projections on the slay and
the recesses in the table or frame.
Another improvement consists in the employment of a knife which is
brought into action at the required time for cutting away the ends of weft
from a spring holder which holds each thread of weft until the shuttle has
gone across and made a pick, and thereby preventing the ends of weft from
coming in contact with the weft fork.
These improvements will be clearly understood by the following particular
description thereof,reference being had to the Figures on the accompanying
two Sheets of Drawings and to the letters of reference marked thereon. In
the various Figures a represents one or both of the side frames of the loom in
whole or in part; b, the breast beam; c, the crank shaft; d, the tappet
shaft e, the slay or batten; and f, the sword arms.
Figs. 1, 2, and 3, Sheet 1, are front and end views of part of a loom pro-
vided with one arrangement of my improvements for changing the shuttle
and removing it from the slay without stopping the loom. To the ordinary

page_text: v
wett fork holder g 1 connect the top of a lever fixed to the rod or tube i
extending across the loom underneath the breast beam and carrying at one end
the levers j, k, Figs. 1 and 2, and at the other end the lever 1, Fig. 3. At
the side of the loom opposite the levers j, k, I place a slide and stud m, n, and
at the other side of the loom a slide and stud o, p; the stud n carries a com-
pound lever with two arms q, r, and at the same side of the loom at that end
of the breast beam there is a platef having-bearings, in which are placed
rollers t carrying a creeper formed of bands of steel or tapes having fixed to
them projections 2, between which are placed the shuttles full of weft ready to
be placed on the slay when required, and at the front of the plate there are
projections for forming the bridge for the shuttle to pass from the creeper
to the slay, there being recesses in the front of the slay for the projections to
passinto. The upper arm g of the compound lever extends upwards to near
the shuttles and the lower arm r to below the tappet won the tappet shaft d,
the upper arın being midway between the bands or tapes of the creeper, and
at the shuttle box at this end of the slay there is a moveable shuttle guard x
connected by rods y to a tie bar z carrying a roller or bowl a', which guard is
raised when required by the lever j, and falls by its own gravity. In the
other end of the slay I form a vertical space a little larger than the shuttle
and employ a moveable slide 61, Fig. 3, for opening and closing the space, the
slide working in guides and abutting against the ordinary stationary shuttle
guard c¹ when the space is closed. In bearings fixed to the bottom of the
slay there is a two-armned lever, the arm / passing through a slot in the slide b
and the arm extending below for being acted on when required by the bent
arm fi on the stud p. When the loom is working the breakage or absence of
weft is detected when the shuttle is returning to the weft fork end, and when
the detection takes place the ordinary sector hammer catches the hook of the
weft fork and gives motion to the weft fork holder g and lever h, the effect of
which is to turn the rod or tube i and cause the lever j to raise the shuttle
guard r, the lever,k to raise the slide m, stud n, and compound lever q,r,
the lever 1, Fig. 3, to raise the slide o, stud p, and bent arm f' the arm r of
the compound lever being placed in contact with the tappet wou the tappet
shaft, the top arm q brought behind the foremost shuttle on the creeper, aud
the bent arm f' in position for acting on the double lever d³, e¹ ; as the slay is
coming to the front the arm e¹ comes in contact with the top of the bent
arm f, and turns back the top arm d², so as to take back the slide b' and
uncover the space in the slay through which the empty shuttle falls into a
receiver. When the crank is near the front centre projections v are in
the recesses in the slay to form a bridge for the shuttle, and as the tappet w
and

page_text: revolves it depresses the arm r, causing the arm q to shift the shuttle over the
bridge and under the raised shuttle guard on to the slay, and as the crank
turus the front centre the bowl a' euters the recess in the lever j to allow the
guard to be slightly lowered and prevent the shuttle from leaving the slay
until the lever j is lowered by the weights of the parts when the sector
hammer is making its return movement. The rod or tube i, Figs. 1, 2, and 3,
and the lever a fixed to it, are common to all the various arrangements of my
improvements, and therefore when in the Figures the rod or tube i is shewn
without the lever hand weft fork holder g it must be understood that motion
is given it in a similar manner to that before described, and in all the Figures
similar letters refer to similar parts.
In the end view, Fig. 4, I shew another arrangement for removing shuttles
with weft from a creeper to the slay. The creeper is formed of tapes or bands
having projections upon them as in Figs. 1 and 2, but to one end of one of the
front rollers t I fix a toothed wheel g¹ pitched to correspond with the width of
the shuttles and work the wheel and creeper by the lever jointed to the
under side of the slay, the lever being raised for the purpose when required
by the lever ¹ou the rod or tube i. At the time the sector hammer catches
the weft fork holder when there is breakage or absence of woft the slay is in a
more backward position than shewn in the Figure, so that when the rod or
tube i is turned the lever ' raises the tip of the lever h' in front of the tooth l¹
of the toothed wheel g¹, for enabling the tip when the slay comes forward to
turn the toothed wheel the distance of a tooth, and shift the foremost shuttle-
over the bridge and under the raised shuttle guard on to the slay, and at the
same time bring forward the next shuttle for the next operation.
In the end view, Fig. 5, I shew the application to loose reed looms of one
of my improved arrangements for removing shuttles from a box or case on a
plain table to the slay, an arm similar to one of the arms or levers for holding
the reed being shown at m³ and the rod to which the arms are fixed at n
The fresh shuttles with weft are contained in the case o' attached to the plain
table p¹ fixed to the loom side at the end of the breast beam, there being a
moveable shuttle guard and lever j on the rod or tube i for working it,
similar to those parts in Figs. 1 and 2. On the rod n' there is a bent lever gi
working loose, having its horizontal part above the bar which supports the
shuttle guard, and at the side of the loom is jointed a two-armed lever ¹, s¹,
the top arm being pointed in a sliding plate t', which can pass through a
space at the back of the case. At the front of the case there is an open space
for allowing the passage of the shuttle, and above the space there is at each
end a spring guide u for preventing the shuttle from rising in its passage to

page_text: the slay, there being projections at the front of the table and slay, and also
recesses in the table and slay, for forming a bridge for the shuttle to ride
on, and also recesses in the shuttle guard for the spring guides to pass through.
At the under side of the table is jointed a small two-armed lever, v², w³, and
through the slay is passed a rod x' having its front end bent downwards and
its back end placed against the lever or arm m². When a change of shuttle
has to take place, the rod or-tube-i is turned as before described, raising the
lever j, the shuttle guard x, and bent lever and as the slay comes forwards
the tip end of the bent lever acts on the arm s, and causes the arm r³ to move
the slide t¹ and shift the bottom shuttle from the case over the bridge on to
the slay, and when the shuttles in the case are exhausted the arm of the
small two-armed lever falls, so that it can act on the rod and force back the
arm or lever m³, and by turning the rod n¹ causes the loom to stop in the
same manner as when a shuttle is lodged in the shed.
In the end view, Fig. 6, I shew another arrangement for removing the
shuttle from the ejection end of the slay, there being a moveable shuttle
guard worked by a lever; in the rod or tube i, similar to those before
described at the other end of the slay. In the back of the shuttle box
there is a hole in which is placed a T-headed pin, encircled at the back by a
spiral spring y, and on the under side of the slay there is a bracket 2, having
a stud carryinga double lever, the lower arm a³ projecting downwardsand the
top arm 62 extending upwards to the back of the pin. At the end of the
loom in line with the breast beam there is a plate or table c², having near
each end a spring d³, and the plate and slay are provided with projections v
and recesses for forming a bridge, there being recesses in the moveable
guard for the springs to pass through when the crank is turning the front
centre.
Just before the shuttle is to be ejected the rod i is turned as before described
and raises the lever; and shuttle guard x, bringing the tip of the lever d³ into
position for acting on the bottom arm a³, and causing the top arm 6² to over-
come the force of the spring y¹, and push the T pin, which in its turn
pushes the shuttle with the broken or absent weft over the bridge on to
the table, where it is slightly held by the springs d' until forced further back
The
by the next shuttle as it is being placed on the table, and so on.
springs are placed in oblique positions, the space between them gradually
narrowing towards the front, the space at the back being a trifle longer than
the length of the shuttle, so that when the table is covered with shuttles the
one which is most backward shall be free of the springs for facility of removal,
but all the others slightly held by the springs."

page_text: Figs. and 8, Sheet 2, are end views, Fig. 9 a front view, and
Fig. 10 a plan of part of a loom provided with another of my improved
arrangements for changing the shuttle and removing it from the slay; and
Figs. 11, 12, and 13 are detached views of some of the parts. To one of
the end frames a I fix a plain table f2, Figs. 7, 9, 10, 11, 12, and 13, in line
with the breast beam, and fix on the table a case 92, Figs. 11, 12, and 18,
for containing a number of shuttles with weft one upon another. To the
under side of the table is fixed the bracket h³, having bearings for a shaft k
carrying the compound levers , m², tho weft fork holder g, the lever h,
the rod or tube i extending across the loom; the lever; and shuttle guard a
are similar to those before described, and are called into operation in the same
manner when there is breakage or absence of weft. On the rod n³ under-
neath the slay I place loose a spring lever 02, the horizontal part passing
between the slay and the bottom tie bar of the shuttle guard x, and to the
slay in front of the compound lever is fixed a projection p². The shuttle case
may be made to hold any convenient number of shuttles; in Fig. 11 it is
shewn to contain five, one upon another, and it is the bottom shuttle that is
to be self-actingly placed onthe slay when a change has to take place, there
being a space in front of the case for the passage of the shuttle, and two slots
at the back for the passage of the arms, and for keeping the bottom shuttle
steady until it is required to be placed on the slay there are two light springs q²,
Fig. 13, which hold the shuttle gently in the case but easily yield and allow
the passage of the shuttle to the bridge and slay when required. When the
loom is working, and there is no breakage or absence of weft, the shuttle
guard rests on the slay, and the tops of the arms are behind the bottom
shuttle in the case. When there is breakage or absence of weft the hammer
seizes the hook of the weft fork to bring forward the fork holder g and leverh,
thereby partly turning the rod or tube i to raise the lever; and shuttle
guard x, the said movements being similar to those before described. As the
shuttle guard is raised its tie bar raises the spring lever o³, so that as the slay
advances the end of the lever shall come in contact with the arm m² and force
it back so as to cause the top arms of the compound levers to be forced
forward and shift the bottom shuttle over the bridge on to the slay, there
being spring guides n³, Fig. 12, fixed to the shuttle case to keep the shuttle
from rising. These operations take place before the crank has arrived at the
front centre, but when the crank is close to the front centre the bowl a¹ dwells
in the recess of the lever, and allows the shuttle guard to drop and hold the
shuttle on the slay, and the projection p* strikes one of the arms to enable
the compound levers to return to their original positions, the top arms 12

page_text: passing from below the shuttles to allow them to fall in the case and then be
ready for a fresh operation. For preventing the picker from obstructing the
shuttle in its passage to its working position on the slay I fix to the top of the
picker a notched plates,and use a lever jointed to the bracket a fixed to the
bottom of the slay. In guides fixed to the bottom part of the front of the slay I
place a bar having a snug w³ projecting downwards, the bar being bent or
formed at one end as at r³, Fig. 10, for passing to the back of the slay, and
to the rod or tube i I fix a lever y having an inclined end. When there is
no change of shuttle the lever is in its forward position, as seen in Fig. 9,
the top of the lever being out of the way of the notched plate s³ on the picker,
but when a change is required and motion given to the rod or tube i the
lever y is raised so that its inclined end shall act on the snug w³ and move
the bar and turn back the lever t³, the top of which strikes the notched
plate s and keeps back the picker, and after the change of shuttle the
picking movement of the picker returns the lever and bar to their original
positions. For holding the end of weft from a fresh shuttle until the shuttle
has gone across and made a pick I employ a spring holder fixed to the
bottom of the slay, the holder closing by its own elasticity, and being
opened by the incline a³ on the bar v³.
In Fig. 10 the incline is seen in contact with the spring, and the holder
is open, but when the bar is pushed back by the lever y² the holder is closed
and holds the weft, and for cutting away the ends of weft from the holder I
employ a knife fixed to the rod or tube i. In all cases after the removal of
the shuttle from the ejection end of the slay the picking stick at that sido
makes a blank pick, there being no shuttle before it, and as there is no weft
the hook of the weft fork would not be lifted, and therefore the sector hammer
would hook and cause the shuttle changing and removing motions to be
called into action when not required, and prevent the proper working of the
loom, and it will be evident that if by any contrivance the hook of the weft
fork is raised the saine as when there is weft that the hammer will not hook
and cause unnecessary change. For raising the hook of the weft fork I
employ a spring 63 fixed to the breast beam, and fix on the rod or tube i a
short lever c, Figs. 8 and 10, underneath the spring, so that when the rod
or tube i is turned for working the motions for changing and removing the
shuttle the short lever c³ shall press against the bottom of the spring 6³ and
cause its top to hold up the hook of the weft fork during the blank pick.
For the removal of the shuttle with broken or absent weft from the ejection
end of the slay there is a vertical space in the slay and a hinged shutter d³,
Figs. 8 and 9. The shutter is hinged to the top of the slay so that when it

page_text: is raised its surface shall be level with the fly plate, but when lowered a
passage will be opened for the shuttle to escape. To the sword arm fat
that side of the loom is fixed the bracket and stud e³, carrying a double lever
having its upper arm f³ passing through the space in the slay to the under side
of the shutter, and its lower arm g³ formed with a projecting plate h³ in
contact with the spring ³ fixed to the sword arm. To the rail 3 is fixed
one end of a strong spring m³ having at the top on one side an incline n
Fig, 9, and at the other side a stud o³, and to the rod or tube i is fixed
a lever p³, Figs. 8, 9, and 10, having one side near the side of the spring ms
and its extreme end formed with a transverse projection 93. When the
sector hammer gives motion to the weft fork holder g, the lever h, and the
rod or tube i the lever ps is raised against the incline n³ and pushes the
spring m³ sideways so as to bring the stud o³ in front of the projecting plate h³,
and when the slay comes forward the plate comes in contact with the stud, and
causes the top arms of the double leverto move towards the jointed side of the
shutter d³, and enable the shutter to fall to allow a free passage for the empty
shuttle to pass through the space in the slay to a stationary table or receiver.
Another of my improvements consists in preventing the picking stick on the
ejection end of the slay from making a stroke. until the shuttle has beendelivered
from the other end. For effecting this object I place on the tappet shaft a
clutch box,one halfon the shaft and the other half fixed to the picking tappet,
and the half of the clutch box on the shaft is shifted at the required time by
a lever put in motion by a lever fixed to the rod or tube i.
In witness whereof, I, the said William Rossetter, have hereunto set
my hand and seal, this Twelfth day of April, in the year of our Lord
One thousand eight hundred and sixty-seven..
