WILLIAM MORGAN-BROWN, of the Firm of Brandon and Morgan-Brown, Engineers,
and Patent Agents, of 38, Southampton Buildings, London, and 1, Rue Laffitte,
Paris. "IMPROVEMENTS IN LOOMS." [A communication from abroad by Frederick
Fosdick, of Fitchburg, Massachusetts, United States of America.]
This Invention relates to looms, and is more especially designed for narrow ware
looms for weaving ribbons, sashes, goring, silks, tapes, and elastic webbings, but may
be used for other well known fabrics of greater width.
This Invention relates to the combination with reciprocating shuttle carriers
adapted to carry the shuttle through the shed of the warp of a shuttle provided
with automatically operating locking devices whereby the reciprocating carriers are
enabled to carry the shuttle positively through the shed of the warp, each carrier
in turn taking the shuttle from one side of the warp and giving it to the other
carrier, preferably at or near the centre of the width of the warp, the carrier
which then receives the shuttle completing the passage of the shuttle through the
said shed.
Also in certain shuttle-levers and connecting devices between them and the heads
of the shuttle carriers whereby the carries are moved rapidly and guided and main-
tained in proper line during their movement, and while delivering and receiving
the shuttle the said connecting devices or sleeves constructed and combined with
the heads and levers to reduce to the minimum friction and binding strain which
usually results when converting a vibrating into a reciprocating movement.
Also in the combination with two shuttle levers of a yielding connecting link
attached at opposite sides of the fulcra of said levers whereby the said levers
are each made to move from the like sides of like cams, so that notwithstanding
r Prien S21

page_text: wear of the said cams the carriers operated by the levers will always come to
the proper position in the warp-shed to correctly surrender and receive the
_shuttle.-
Also in a rotating shaft and connected pawl, and a loose ratchet-and-gear_on_the.
-said.shaft.combined with an adjustable pawl controller, a sand or take up roller
and-intermediate connections between the gear attached to the ratchet, and a gear
-attached-to the sand roller whereby by adjustment of the pawl-controller the rate
at which the fabric is taken away from the reed may be varied according to the
quality of the fabric or the desired closeness of the weft.
The frame of the loom, of proper shape to hold the working parts, has bearings
to support the main shaft driven in any usual way from a belt on pulley.
The main shaft has two hubs grooved peripherically, each hub having two throw
portions at diametrically opposite sides of the bub. The said grooves each receive
a pin or roller of one of the shuttle levers. Each of these levers has two ears or
openings to permit the connection with them of the ends of a yielding connecting
link composed of two socketed portions, a rod fitted to slide with relation to the
sockets, and an intermediate spring, the said link being connected at one end with
one lever in front of its fulcrum, and with the other lever at the rear of its fulcrum.
whereby the said pins or rollers of the levers are through the action of the spring
kept pressed against like side walls of two cams which ensures a like and equal
movement of the levers at each throw forward, and enables the shuttle carriers to
terminate their forward or inward movement at proper positions between the warp
threads so as to correctly transfer the shuttle from one to the other carrier at each
pick.
Cross heads are fitted to slide on a guide rod, and have the shuttle carriers
attached to their upper parts by screws, and the said carriers are adjusted to project
more or less from the heads by means of adjusting screws.
Each of these cross heads has a rigid foot which enters one of the openings in one
of the compound sleeves, the said sleeves forming the connecting devices between
the levers and heads.
Each of these compound sleeves has two openings through it at right angles each
to the other, and the openings not entered by the feet of the cross heads are entered
by the ends of the shuttle-levers, they sliding in and out of the openings of the
compound sleeves while the levers in their vibration reciprocate the cross heads on
the guide rod. The feet of the said cross-heads during such movement oscillate in
the vertical openings of the compound sleeves.
The reduced ends of the shuttle levers and the sleeves are of such length and so
located with reference to each other and the guide rod that in the vibration of the
shuttle-levers they have in both their forward and backward motions a direct push
and pull in the centre line of the resistance to be overcome, thereby obviating
tendency to exert binding strain between the levers and compound sleeves and cross
-head:
The foot of the cross head is so far extended into the opening of the compound
sleeve as to ensure the maintenance of the shuttle carrier and shuttle in proper
vertical position throughout its reciprocations.
The heddle frames provided with any desired kind of heddles are adjustably.
connected with heddle levers by means of suitable connecting rods.
The said levers are provided with pins or rollers to enter grooves at the sides of
heddle operating cams, all of usual form, on the shaft which derives its motion from
the main shaft through a suitable train of gearing.
The reed or beater is held in any usual manner at the top of its carrying arm,
the said arm being actuated by an adjustable pitman having a forked end to
embrace the main shaft, and also a pin or roller to enter a groove in the reed
operating cam.
The grooves of the cams are so shaped and arranged with relation to the shaft
and other working parts that while the shuttle levers are at rest at opposite sides
of the loom the reed will be quickly thrown forward to beat up the weft and be

page_text: returned, after which, while the reed remains at rest at its back stroke, the shuttle
carriers will be quickly thrown to the centre of the loom to carry and take the
shuttle across the warp and through the shed, each carrier returning to its position
at the outer edges of the warp.
The shuttle carriers are enlarged at their outer ends and grooved to embrace the
flanged edges of metallic back plate of the shuttle the carrier when so engaged
with the shuttle, embracing it, and preventing it from tipping or wabbling.
Each carrier is provided with a spring catch and with a so-called key, the latter
having a ward or lug.
The back plate of the shuttle has a deep longitudinal groove to receive a sliding
wedge provided with inclines or cams, and at each side of the groove which
receives the wedge bar are shoulders having their ends inclined at the ends of the
shuttle.
The shuttle has pivotted at its back a double ended latch having bevilled faced
hooks.
The wedges or cams on the wedge bar have their inclined faces toward each
other, and the cams are so shaped and they are at such distance apart with relation
to the length of the latch that as one end of the latch is being raised by one cam
the other end descends into the space between the two cams.
Supposing that the two carriers are approaching each other from opposite sides
of the loom, and that the shuttle is connected with the left hand carrier,
Now when the right hand carrier meets the shuttle it first, by means of its grooves,
engages the back plate of the shuttle and then the end of the key strikes the end
of the wedge bar and moves it longitudinally until the cam at the right hand end
of the said bar lifts the right hand hook of the latch, the simultaneous removal of
the left hand cam from under the left hand end of the latch permitting it to turn
on its pivot.
This movement of the latch releases a spring catch at the left hand of the shuttle,
and at the same time causes the kook of the carrier then embracing the right.
hand end of the shuttle to be engaged by the hook at the right hand end of the
latch.
In this way each key is made alternately to move the wedge bar, actuate the
pivoted latch, and engage and release first one and then the other of the spring
catches of the carriers, thereby permitting the shuttle to be automatically transferred
from one to the other carrier within the shed of the warps, the carriers carrying the
shuttle positively through the shed from selvedge to selvedge of the warp.
The end of the key and catch part are at such distance apart as will ensure
the engagement of the catch part at the proper time with the said hooks of the
latch.
The end of the key as the shuttle carrier meets the end of the shuttle and is
engaged by it, strikes the end of the wedge bar and moves it the proper distance
to operate the pivoted latch, the end of the key during the movement of the
wedge bar by it travelling along the inclines, but as soon as the wedge bar has been
moved far enough portions of the key wider than the wedge bar come upon the
shoulders at the sides of the bar which so operate the said key as to clevate or
remove its end from contact with the end of the wedge bar, which then remains at
rest.
As a key is lifted from the ends of a wedge bar by one of the inclines a projection
of the said wedge bar comes in contact with one of the stops of the shuttle and
bolds the wedge bar so that the inclined catch part of a spring catch may strike
and ride over the inclined face of one of the hooks of the latch and become engaged
with that end of the latch while elevated by a cam of the wedge bar.
The wedge bar, its cams, and the double hooked latch constitute an automatic
lock which is operated by the key plate of the carrier.
In operation, the movement of shuttle and carriers is very rapid, and the lock
would fail to operate correctly if the wedge bar should by momentum or rebound
get out of position,

page_text: To obviate any accidental retrograde movement of the said wedge bar a ward
with an inclined face has been placed on the key, the said ward when the key is
lifted-from-contact-with-the-end-of-the-wedge-bar, as described, coming_to_a_position
near the end of the wedge bar so as to arrest the accidental backward movement of
the said wedge bar.
The woven fabric is taken away from-the-cloth making point by means of a so
called sand roll provided with a worm gear actuated by a worm on a shaft beld in
an oscillating bearing having its centre of motion on a shaft, the said bearing being
provided with a hook to be caught by a latch to retain the worm and worm gear iu
engagement or permit them to be disengaged if it is desired to actuate the sand
-roller shaft-by-a hand wheel..
The fabric passes over the curved beam, under the sand roller, thence up, over,
and about a presser roller, and thence down to a fabric receiving roller supported
by adjustable brackets.
This roller derives its motion from a sprocket wheel on the sand roller shaft,
which by a chain or other belt is connected with a sprocket wheel on the shaft of
the said receiving roller.
The adjustable brackets permit the chain or belt to be removed or to be
tightened.
The shaft has at its rear end a bevel pinion which is engaged and moved by a
bevel pinion rigidly attached to a ratchet gear placed loosely, upon the main shaft
and actuated intermittingly by a pawl connected with an ear of an annular sleeve
fixed upon and rotating with the shaft by means of a set screw.
The said pawl has projecting from it a rest and a tooth, which latter engages the
teeth of a ratchet wheel when permitted so to do by a pawl controller, the said pawl
at all other times being kept out of engagement therewith by the rest, which then
rides upon the pawl controller.
This pawl controller is composed of two discs having portions of their peripheries
cut away for a certain distance, and placed to surround but which are not connected
⚫ with the main shaft.
The one disc forms a part of a stationary case, and the other disc placed loosely
beside it is provided with a set-screw extended through a circular slot.
By adjusting the one disc with relation to the other disc the space between the
corners of the discs may be increased or diminished to regulate the time during
each revolution of the sleeve and main shaft that the pawl shall be permitted to be
thrown by a spring into position for its tooth to engage and actuate the ratchet gear,
and consequently turn the shaft and actuate the sand roller.
The rest of the pawl is of sufficient length to ride upon the edges of both discs,
and the tooth is then held up out of engagement, but when the rest is permitted to
fall, as it will do while moving between the corners, the ratchet will be engaged and
turned, consequently the time during which the ratchet wheel will be actuated by
the pawl will depend upon the distance between the corners.
The holding device shown as a thumb screw confines the disc in adjusted position,
and if desired the case may be provided with a suitable scale to designate the speed
of the sand roller, and consequently the number of picks to the inch.
A lever or treadle will operate a clutch of suitable construction to release the belt
pulley to stop the loom.

with automatically operating locking devices, substantially as hereinafter described,
whereby the reciprocating carriers are enabled to carry the shuttle positively
through the shed of the warp, each carrier in turn taking the shuttle from one side
of the warp, and giving it to the other carrier, preferably at or near the centre of
the width of the warp, the carrier which then receives the shuttle completing the

with the heads and levers to reduce to the minimum friction and binding strain
which usually results when converting a vibrating into a reciprocating movement.
Also, in the combination with two shuttle levers, of a yielding connecting link
attached at opposite sides of the fulcra of said levers, whereby the said levers are
each made to move from the like sides of like cams, so that notwithstanding wear
of the said cams, the carriers operated by the levers will always come to the proper
position in the warp shed, to correctly surrender and receive the shuttle.
Also in a rotating shaft and connected pawl, and a loose ratchet and gear on the
said shaft, combined with an adjustable pawl controller, a sand or take up roller
and intermediate connections between the gear attached to the ratchet, and a gear
attached to the sand roller, whereby by adjustment of the pawl controller, the rato
at which the fabric is taken away from the reed may be varied according to the
quality of the fabric, or the desired closeness of the weft.
Also, in details of the shuttle and shuttle carriers, as will be hereinafter set forth
and specifically referred to in the claim.

Shaft b-has-two hubs.grooved peripherically, each hub having two throw portions
at diametrically opposite sides of the hub. The said grooves each receive a pin or
roller-2-of-one-of-the-shuttle levers.e, the said levers (one only being fully shown),
-having-their-fulcra each at 3. Each of these levers e has two ears or openings 4, 5,
-(see-Figure-1); to permit the connection with them of the ends of a yielding con-
necting-link f, shown as composed of two socketted portions 6, 7, a rod 8 fitted to
slide with relation to the sockets, and an intermediate spring gas shown in Figure 1,
the said link being connected at one end with one lever in front of its fulcrum 3,
and with the other lever at the rear of its fulcrum, whereby the said pins or rollers
2 of the levers e are, through the action of the spring q, kept pressed against like
side walls of the two cams d, which ensures a like and equal movement of the
levers at each throw forward, and enables the shuttle carriers to terminate their
forward or inward movement at proper positions between the warp threads, so as
to correctly transfer the shuttle from one to the other carrier at each pick.
By changing the link from the position shown in Figure 1, and attaching its
ends to the unoccupied ears 4, 5, the rollers or pins 2 will be pressed hardest against
the opposite side walls of the cam grooves which move the levers e.
The cross heads g fitted to slide on the guide rod i, have the shuttle carriers h, h¹,
attached to their upper parts g' by screws 18, and the said carriers are adjusted to
project more or less from the heads by means of adjusting screws n².
Each of these cross beads has a rigid foot 10 which enters one of the openings in
one of the compound sleeves j, the said sleeves forming the connecting devices
between the levers and heads.
Each of these compound sleeves has two openings through it at right angles each
to the other, and the openings not entered by the feet of the cross heads are
entered by the ends 12 of the shuttle levers, they sliding in and out of the openings
of the compound sleeves, while the levers in their vibration reciprocate the cross
heads on the guide rod . The feet 10 of the said cross heads, during such move-
ment, oscillate in the vertical openings of the compound sleeves.
The reduced ends 12 of the shuttle levers and the sleeves j are of such length,
and so located with reference to each other and the guide rod i, that in the
vibration of the shuttle levers e, they have in both their forward and backward
motions a direct push and pull in the centre line of the resistance to be overcome,
thereby obviating tendency to exert binding strain between the levers and com-
pound sleeves and cross head.
The foot 10 of the cross head is so far extended into the opening of the compound
sleeve as to ensure the maintenance of the shuttle carrier and shuttle in proper
vertical position throughout its reciprocation..
The heddle frames provided with any desired kind of heddles are adjustably
connected-with-heddle-levers 6 by means of suitable connecting-rods m...
The said levers 6 are provided with pins or rollers to enter grooves at the sides
of heddle operating cams n, all of usual form on the shaft o, which derives its motion
from the main shaft 6 through a suitable train of gearing, see Figure 1, some of the
said gearing being shown by dotted lines, Figure 7.
The reed or beater p is held in any usual manner at the top of its carrying arm
q, pivotted at 14, the said arm being actuated by an adjustable pitman r, having a
forked end to embrace the main shaft b, and also a pin or roller to enter a groove
15 in the reed operating cam s (see detail, Figure 14).
The grooves of cams d and s are so shaped and arranged with relation to the
shaft b and other working parts, that while the shuttle levers are at rest at opposite
sides of the loom, the reed will be quickly thrown forward to beat up the weft and
be returned, after which, while the reed remains at rest at its back stroke, the
shuttle carriers will be quickly thrown to the centre of the loom to carry and take
the shuttle across the warp and through the shed, each carrier returning to its
position at the outer edges of the warp.

page_text: The shuttle carriers h, h, are enlarged at their outer ends (see Figure 2), and
grooved as at 19 (see Figure 5) to embrace the flanged edges 20 of the metallic
back plate 21 of the shuttle i, as in the sectional view, Figure 4; the carrier when
so engaged with the shuttle, embracing it and preventing it from tipping or
wobbling.
Each carrier is provided with a spring catch j, and with a so called key k¹, the
latter having a ward or lug 20.
The lock plate of the shuttle has a deep longitudinal groove ax to receive a
sliding wedge provided with inclines or cams 22, and at each side of the groove
which receives the wedge bar are shoulders 25, having their ends inclined as at 26
(see Figure 3) at the ends of the shuttle.
The shuttle has pivotted at its back a double ended latch m', having bevilled-
faced hooks 24.
The wedges or cams 22 on the wedge bar have their inclined faces toward each
other, and the cams are so shaped and they are at such distance apart with relation
to the length of the latch m' that as one end of the latch is being raised by one
cam 22, the other end descends into the space between the two cams, as shown'in
Figure 3.
Referring to Figure 3, it will be supposed that the two carriers are approaching
each other from opposite sides of the loom, and that the shuttle is connected with
the left hand carrier.
Now when the right hand carrier meets the shuttle, it first by means of its grooves
19 engages the back plate of the shuttle, and then the end of the key strikes the
end of the wedge bar and moves it longitudinally until the cam 22 at the right
hand end of the said bar lifts the right hand hook 24 of the latch m², the simul-
taneous removal of the left hand cam 22 from under the left hand end of the latch
permitting it to turn on its pivot.
This movement of the latch releases the spring catch at the left hand of the
shuttle, and at the same time causes the hook of the carrier h¹ then embracing the
right hand end of the shuttle to be engaged by the hook 24 at the right hand end
of the latch.
In this way each key k³ is made alternately to move the wedge bar, actuate the
pivotted latch, and engage and release first one and then the other of the spring
catches of the carriers h, h², thereby permitting the shuttle to be automatically
transferred from one to the other carrier within the shed of the warps, the carriers
carrying the shuttle positively through the shed from selvedge to selvedge of the
warp.
The end of the key k₁ and catch part 31 are at such distance apart as will ensure
the engagement of the catch-part at the proper time with the said hooks 24 of the
latch m'.
The end of the key, as the shuttle carrier meets the end of the shuttle and is
engaged by it, strikes the end of the wedge bar and moves it the proper distance
to operate the pivotted latch, the end of the key k' during the movement of the
wedge bar by it travelling along the inclines 26, but as soon as the wedge bar has
been moved far enough, portions of the key wider than the wedge bar come upon
the shoulders 25 at the sides of the bar, which so operate the said key as to elevate
or remove its end from contact with the end of the wedge bar, which then remains
at rest.
As a key is lifted from the ends of a wedge bar by one of the inclines, a projec-
tion 29 of the said wedge bar comes in contact with one of the stops 28 of the
shuttle and holds the wedge bar, so that the inclined catch part 31 of a spring catch
may strike and ride over the inclined face of one of the hooks 24 of the latch,
and become engaged with that end of the latch while elevated by a cam of the
wedge bar.
The wedge bar, its cams, and the double hooked latch constitute an automatic
lock, which is operated by the key plate of the carrier.

page_text: would fail to operate correctly if the wedge bar should by momentum or rebound,
get out of position.
"To obviate any accidental retrograde movement of the said wedge bar, a ward 20
with an inclined face has been placed on the key, the said ward when the key is
lifted from contact with the end of the wedge bar, as described, coming to a position
near the end of the wedge bar, so as to arrest the accidental backward movement of
the said wedge bar.
-The woven fabric is taken away from the cloth making point by means of a so
called sand roll a³, provided with a worm gear 6s, actuated by a worm c³ on a
shaft d³ held in the oscillating bearing es, having its centre of motion on shaft b
the said bearing being provided with a hook ƒ³, to be caught by a latch g³, to
retain the worm and worm gear in engagement, or permit them to be disengaged if
it is desired to actuate the sand roller shaft h³ by the hand wheel i³.
The fabric passes over the curved beam under the said roller, thence up, over,
and about the presser roller ³, and thence down to the fabric receiving roller 13,
shown separately in Figures 8 and 9, it being supported by adjustable brackets ³

The shaft d³ has at its rear end a bevel pinion g³ (shown in Figure 1, and dotted
in Figure 7), which is engaged and moved by the bevel pinion & rigidly attached to
a ratchet gear t, placed loosely upon the main shaft b, and actuated intermittingly
by a pawl u³, connected with an car of an annular sleeve w³, fixed upon and rotating
with the shaft b by means of a set screw 2³.
The said pawl us has projecting from it a rest a' and a tooth b*, which latter
engages the teeth of the ratchet wheel t³ when permitted so to do by a pawl con-
troller, the said pawl at all other times being kept out of engagement therewith by
the rest a³, which then rides upon the pawl controller.
This pawl controller is shown as composed of two discs c, d, having portions of
their peripheries cut away for a certain distance and placed to surround, but which
are not connected with the shaft b.
The disc d' is shown as forming a part of the stationary case es, and the disc c
placed loosely beside it is provided with a set screw extended through a circular
slot (see Figure 7 and dotted lines, Figure 12).
By adjusting the disc c with relation to the disc d', the space between the
corners 16, 17, of the discs may be increased or diminished to regulate the time
during each revolution of the sleeve us and shaft b, that the pawl shall be permitted
to be thrown by its spring g' into position for its tooth 6' to engage and actuate
-the-ratchet-gear-ts, and consequently-turn the shaft ds and actuate the "sand
roller a³.
The rest a of the pawl is of sufficient length to ride upon the edges of both
discs, and the tooth b* is then held up out of engagement, but when the rest a¹ is
permitted to fall as it will do while moving between corners 16, 17, the ratchet
will be engaged and turned, consequently the time during which the ratchet wheel
will be actuated by the pawl n³ will depend upon the distance between the
corners 16, 17.
The holding device shown as a thumb screw h* confines the disc c* in adjusted
position, and if desired the case may be provided with a suitable scale to
designate the speed of the sand roller, and consequently the number of picks to
the inch.
The lever or treddle 33 will operate a clutch of suitable construction to release
the belt pulley c to stop the loom.
Having thus described and particularly set forth the nature of the said Inven-

page_text: tion, and the manner of carrying the same into effect, I would have it understood
