Improvements in or connected with Looms for Weaving Ribbons,
Webbing, and other like narrow Ware or Fabrics.
I, EDWARD HOLLINGWORTH, of Hutchinson, Hollingworth, and Company,
Limited, of Dobcross Loom Works, Dobcross, in the County of York, Loom
Makers, do hereby declare the nature of this invention to be as follows:-
This invention relates to those. looms that are specially constructed and
arranged. for weaving simultaneously a series of ribbons, webbings for braces
or suspenders, and analagous narrow ware or fabrics, and comprises; firstly,
the application to said looms of a new or improved motion for actuating the
ordinary parts by which the several shuttles are traversed backwards and for-
wards through their separate "sheds," secondly, a take-up motion actuated by
the movement of the loom for rotating the take-up shaft and therefore, the whole
of the take-up or sand rolls or drumis mounted thereon to take up or wind on
the ribbons or narrow ware as the weaving of same proceeds;, and thirdly, the
application to each take-up roll or drum of a separate or supplementary take-up
mechanism whereby any individual roll or drum may be revolved by hand either
forward or backward to wind on or unwind the ribbon or fabric thereon, inde-
pendently of the take-up shaft when required in the case of a shuttle thread
breaking or for any other reason. In carrying out the first part of my invention
1 dispense with the treadles and treadle motion at present employed for actuating
the shuttles, and, in lieu thereof, I apply to the foom a suitable combined gear
motion for revolving intermittently a short shaft arranged at right angles to
the crank shaft and carrying at its front end a lever or arm to which are attached
the ordinary wires connected to the longitudinal rack which, through the medium
of pinions, causes the shuttles to be traversed to and fro through their respective
"sheds." The said motion comprises a series of three spur wheels, though I do
not confine myself to the number that may be employed, or to the order of
arrangement hereafter described, as such number of wheels or order of arrange-
ment might be varied and still accomplish the purposes of this part of my
invention. One of the said spur wheels, namely, the driver, is fast on the
crank shaft of the loom and gears with a carrier or intermediate wheel on a
fixed stud said carrier wheel in turn gearing with and driving the third spur
wheel which is mounted on a short stud shaft and turns loosely thereon. On
the face of the last named spur wheel is a bevel wheel and, at a given distance
therefrom and also loosely mounted on the same stud shaft is a double bevel
wheel. Between the first bevel or mitre wheel on the driven spur wheel and
the double bevel or mitre wheel, and gearing with both, is a third bevel or
mitre wheel mounted loosely on a stud attached to or forming part of a swinging
arm or lever centred on the stud shaft and provided with a longitudinal slot
or recess into or through which extends a stud or pin secured in a radial slot
in the carrier or intermediate spur wheel. When the loom is running, motion
as imparted from the spur wheel on the crank shaft to the carrier wheel and
through said carrier to the spur wheel on the stud shaft which, through the

page_text: "
medium of the bevel wheel on the face thereof gives constant rotary motion in
one direction to the intermediate bevel on the end of the swinging lever. The
said swinging lever is oscillated constantly by the crank pin on the intermediate
spur wheel and causes the intermediate bevel to be moved in a semi-circular
path backward and forward, without interfering with its rotary motion. In one
stroke of its movement the said intermediate bevel is constrained to drive the
double bevel wheel, but, in the return or reverse stroke it runs harmlessly in
the teeth of the double bevel without imparting motion thereto so that in one
stroke the double bevel is revolved, and in the return or reverse stroke it remains
stationary. The intermittent rotary motion thus given to the double bevel is
transmitted therefrom through another bevel wheel to the short shaft first
herein mentioned which, by means of the lever on the front end thereof and
the ordinary wire connections actuates the longitudinal rack to drive the pinions
and traverse the shuttles from side to side of their respective "sheds" and back
again, the cessation of motion during the return or reverse stroke of the swing
lever giving the required "dwell" to the shuttles at each side of the sheds.'
The period of "dwell" may be shortened or lengthened as desired, by moving
the crank pin or stud on the carrier wheel nearer to or further from the axis
of said wheel so as to give a more rapid or a slower movement to the swinging
arm and to the shuttles, this alteration of the dwell" in nowise affecting the
extent of the backward and forward traverse of the shuttles which remains the
same throughout. Referring now to the second part of my invention, I impart
the requisite motion to a spur wheel fast on the take-up shaft by a suitable
system of speed gearing or pinions (which may be changeable), driven from a
short shaft at the side of the loom and receiving its motion, through mechanism
hereafter described, from a suitable part of the lathe sword or going part, or
from the centre on which said going part oscillates. The lever or arm moving
with the loom, and from which I preferably obtain the motion, is provided with
a screw on which is a nut or block alapted to be moved up or down said screw
to alter the point of connection and the throw of an adjustable connecting link
or rod attached to or forming part of said nut or block. The opposite end of
the adjustable connecting link is secured to a lever or arm secured externally
to a hollow drum or sheath mounted loosely on the before named short shaft,
within the said drum and centred on studs supported in the sides thereof are a
series of catches which are forced by springs against the teeth of a ratchet wheel
located within the drum or sheath and also loosely mounted on the short shaft,
the number of catches and their disposition within the hollow drum being
such that some of said catches will always engage with teeth on the ratchet wheel
no matter how slight the movement may be, and, therefore, while driving it,
they also prevent any backward movement. On the face of the ratchet wheel
is a gear wheel, or it may be a clutch box, while on a separate disc secured by
key on the short shaft is a similar opposing gear wheel or clutch box, the disc
being also provided with recesses for holding spindles or fingers on which are
confined spiral springs. A hand wheel is employed to turn the short shaft by
hand and a nut is applied by which the ratchet wheel (or it may be the disc) is
forced laterally to place the gear teeth thereon into engagement with the oppos-
ing gear teeth on the disc, the springs on the spindles serving to disengage said
parts when the nut is unscrewed. When the parts are in gear, the reciprocation
of the arm fixed to the hollow drum or sheath gives to the ratchet wheel a step
by step progressive motion which is transmitted through the disc to the short
shaft and thence through the speed gearing and spur wheel to the take-up shaft
on which the whole of the take-up rolls or drums are mounted and driven
collectively thereby to take up the narrow ware being woven. I may employ
any suitable device or devices for adjusting or setting such of the parts as may
be required. In order to admit of any individual take-up roll or drum of the
series mounted on the common take-up shaft being revolved forward or backward
independently of said take-up shaft as may be necessary from time to time in

page_text: case of a shuttle thread breaking or for any other reason, I employ independent
supplementary mechanism to each roll or drum and comprising, in each case, a
hand wheel loosely mounted on the take-up shaft and having an eccentric hub
or boss. A shell, also provided with a hub, is secured on the take-up shaft
contiguous to the eccentric hub of the hand wheel and is provided with external
gear teeth on the end adjacent to said eccentric hub. Within the inner end of
the take-up roll or drum is arranged what may be termed a combination gear
rim having a central concentric opening into which extends the eccentric hub
portion on the hand wheel. The combination gear rim has external gear teeth
on the periphery thereof, the number of which is less than the number of teeth
in the drum with which they are adapted to engage; and said combination
gear rim has also internal gear teeth, the number of which is greater than that
of the teeth on the shell, and are adapted to engage therewith. The combination
gear rim is made to turn freely on the eccentric hub or boss of the hand wheel,
and the external and internal gear teeth thereon are concentric with the central
opening in sail gear rim. A collar secured on the take-up shaft holds the hand
wheel in place against the inner edge of the take-up roll or drum, and the
take-up roll or drum in place on the shell, while an internal annular flange on
the drum extends over the inner edge of the periphery of the shell. The
eccentricity of the hub or boss of the hand wheel is approximately equal to the
length of a tooth on the combination gear rim plus any additional amount for
clearance. The operation of said supplementary and individual take-up
mechanism is as follows:-
When the take-up shaft revolves in the ordinary operation of the loom, as
before described, the shell fast thereon will revolve with it and will carry the
take-up roll or drum and the hand wheel through the combination gear loosely
mounted on the eccentric portion of the hand" wheel. When it is desired to
cause any individual take-up roll or drum to turn in either direction inde-
pendently of the take-up shaft and while said shaft continues to revolve, the
hand wheel to said take-up roll, being loose on the shaft, is turned in one direc-
tion or the other according to whether it is desired to turn the take-up roll or
drum forward or back, and, in thus rotating said hand wheel, the eccentric
hub portion thereon revolves within the concentric central opening in the
combination gear rim and moves said rim so that the internal gear teeth of same
will be engaged continually with the gear teeth on the shell throughout any
movement of the hand wheel and eccentric and, in one revolution of the hand
wheel, all the gear teeth on the shell will have been engaged by the internal
gear teeth on the combination gear, rim, and if there are one or more of said
internal gear teeth than there are gear teeth on the shell, the movement of the
combination rim will be advanced beyond its original position by the difference
in the number of teeth between one part and the other. An operation of a
similar nature will take place between the gear teeth in the drum or take-up
roll, and the external gear teeth on the gear rim during the same revolution
of the hand wheel and there being more teeth in the drum than on the periphery
of the gear rim, they will be advanced or moved forward in the same direction
around the latter teeth as the internal teeth are advanced around the teeth on
the shell, and the movement of the take-up roll concerned, independently of
the take-up shaft, for one revolution of the hand wheel will be approximately
equal to the combined movement or advancement of the outer gear of the rim
aud the gear of the drum or take-up roll. The continued revolution of the hand.
wheel will cause the take-up roll to revolve on the shaft to any extent desired
either forward or backward. When any force is applied to rotate the take-up
roll or drum on the take-up shaft without the aid of the hand wheel, the said
drum, by reason of the multiplying power of the hand wheel and also of the
cccentric hub thereon, will remain positively in any position given to it by the
hand wheel so that there will then be no backward or forward movement apart
from that given through the take-up shaft. We may vary the details of con-

page_text: struction of said individual take-up mechanism somewhat from the construction
described.

Improvements in or connected with Looms for Weaving Ribbons,
Webbing, and other like narrow Ware or Fabrics.
I, EDWARD HOLLINGWORTH, of Hutchinson, Hollingworth, and Company,
Limited, of Dobcross Loom Works, Dobcross, in the County of York, Loom
Makers, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:-
This invention relates to those looms that are specially constructed and
arranged for weaving simultaneously a series of ribbons, webbings for braces
or suspenders and analagous narrow ware or fabrics and comprises; firstly,
the application to said looms in lieu of the treadles and treadle motion at present
employed, of a new or improved motion for actuating the ordinary parts by
which the several shuttles are traversed backwards and forwards through their
separate sheds"; secondly, a take-up motion actuated by the movement of
the loom for rotating the take-up shaft and therefore, the whole of the take-up
or sand rolls or drums mounted thereon simultaneously to take up or wind on
the ribbons or narrow ware as the weaving of same proceeds; and, thirdly, the
application to each individual take-up roll or drum of an improved separate
or supplementary take-up mechanism for connecting them with the common
take-up shaft to cause them to revolve therewith and for disconnecting them to
permit them to be revolved independently thereof whereby any individual roll
or drum may be revolved by hand either forward or backward to wind on or
unwind the ribbon or fabric thereon, independently of the take-up shaft, when
required in case of a shuttle thread breaking or for any other reason.
In the accompanying drawings forming a part of this specification,
Fig. 1 is perspective view of my improved dwell-gear shuttle motion for narrow
ware looms.
Figs. 2 and 3 are enlarged elevations in perspective of the attachment preferred
with said motion for moving the rack rod swivel in a straight or approximately
straight line;
Fig. 4 is side elevation of my improved take-up motion for rotating the take-up
shaft and take-up rolls thereon to take up the ribbons or narrow ware as the
weaving proceeds;
Fig. 5 is a central vertical section taken on line a, b, of Fig. 4;
Fig. 6 is a central vertical section of a take up roll and hand wheel mounted
on the take up shaft and provided with my improved take-up mechanism for
connecting the take up roll to the take up shaft, or disconnecting it therefrom;
Fig. 7 is a side view looking in the direction of arrow c Fig. 6;
Fig. 8 is a similar side view, the hand wheel being removed to shew the
arrangement of the gear teeth and one of the gear teeth rims partially broken
away or shewn in section to shew the gear teeth under same; and
Fig. 9 corresponds to Fig. 8 excepting that the gear teeth rim shewn in said
figure is removed.
Referring to Figs. 1, 2, and 3 illustrating the dwell gear shuttle motion com-

page_text: prising the first part of my invention, numbers 1, 2 and 3 represent a series of
three spur wheels though I do not confine myself to the number that may be
employed or to the order of arrangement of same hereafter described, as such.
number of gear wheels, or order of arrangement might be varied and still accom-
plish the purposes of this part of my invention. The spur wheel 1, which is
the driver, is fast on the crank shaft 4 of the loom and gears with the second
spur wheel or carrier or intermediate wheel 2 mounted loosely on a fixed stud 5,
secured to the loom framing 6, said carrier wheel in turn gearing with and
driving the third spur wheel 3 which is mounted on a short stud shaft 7 and turns
loosely thereon.
F
On the face of the last named spur wheel 3 is a bevel wheel S and, at a given
distance therefrom and also loosely mounted on the same stud shaft 7, is a similar
opposing bevel wheel 9 having on the back thereof a smaller bevel wheel or
pinion 10 integral with or secured to said bevel wheel 9. Between the first bevel
or mitre wheel 8 on the driven spur wheel and the bevel or mitre wheel 9 and
gearing with both, is a bevel or mitre wheel 11 mounted loosely on a stud
attached to or forming part of a swinging arm or lever 12 centred on the stud
shaft 7 and provided with a longitudinal slot or recess 13 into or through which
extends a stud or pin 14 passing through a radial slot 15 in the carrier or inter-
mediate spur wheel 2 and adjustably secured thereto.
When the loom is running, motion is imparted from the spur wheel 1 on the
crank shaft 4 to the carrier wheel 2 and through said carrier wheel to the spur
wheel which, through the medium of the bevel wheel 8 on the face thereof
gives constant rotary motion in one direction to the intermediate bevel 11 on
the end of the swinging lever. The said swinging lever is oscillated constantly
by the crank pin 14 on the intermediate spur wheel 2 and causes the intermediate
bevel 11 to be moved in a semi-circular path backward and forward without
interfering with its rotary motion. In one stroke of its movement the said
intermediate bevel 11 is constrained to drive the bevel wheel 9; but, in the return
or reverse stroke it runs harmlessly in the teeth of said bevel without imparting
motion thereto so that in one stroke the double bevel is revolved and in the
return or reverse stroke, it remains stationary.
The intermittent rotary motion thus given to the bevel wheel 9, and therefore
to the bevel or pinion 10 forming part thereof, is transmitted therefrom through
another bevel wheel 16 to a short shaft 17 arranged at right angles to the crank
shaft of the loom and supported at each end in bearings in brackets 18, 18. The
intermittent motion thus imparted to the shaft 17 is transmitted by a lever and
the ordinary wire connections 19, 19, to the usual longitudinal rack whose
traverse to and fro across the loom drives the pinions which propel the shuttles
from side to side of their respective "sheds" and back again, the cessation of
motion during the return or reverse stroke of the swing lever as before described
giving the required "dwell" to the shuttles at each side of the "sheds." The
period of dwell" may be shortened or lengthened as desired, by moving the
crank pin or stud 14 on the carrier wheel nearer to or further from the axis of
said wheel so as to give a more rapid or slower movement to the swinging arm 12
and to the shuttles, this alteration of the dwell in nowise affecting the extent
of the backward and forward traverse of the shuttles which remains the same
throughout.
"
"
The wire or cord connections 19, 19, may be attached or secured to a swivel 20
carried by an ordinary lever arm fast on the end of shaft 17, but I prefer the
attachment or motion shewn in Figs. 1, 2, and 3 and hereafter explained for
the reason that a radial or lever arm fast on the shaft 17 travels the swivel 20
in a circular path, whereas it is advantageous to the shuttle motion that the
said swivel should be made to travel as near a straight line as is practicable so
that angular variation in the movement of the points of connection of the
wires 19, 19 shall be minimised.
The stand or bracket 18 at the front end of shaft 17 is made with arms 21 to

page_text: .
which is fastened an internal gear 22 into the teeth of which meshes a spur
gear 23 (Figs. 2 and 3) mounted on a wrist pin or stud 24 on the extremity of
an arm or crank 25 fast to the end of shaft 17.
Fast to said spur wheel or pinion 23 is a slotted arm 26 to which the swivel 20
is adjustably secured. As the shaft 17 revolves half a revolution every pick,
the swivel 20 is passed from one side to the other, or half a revolution.
The gear 23 having half the number of teeth of the internal gear 22, it will
be seen that the gear 23 must revolve one revolution as the arm 25 revolves
half-way around the centre of shaft 17 the said gear or pinion as it turns about
the centre 24 moving the swivel 20 across the plane of the axis of shaft 17 in
approximately a straight line, as will be understood by the positions of said
swivel and pinion shewn at Figs. 2 and 3. When the swivel 20 is the same
distance from the centre 24, as the gear 23 is from the centre of shaft 17, the
said swivel travels as before stated, but if the swivel is moved toward the centre 24
Gr away from same to increase or decrease the throw, the amount it is moved is
the amount it varies from a straight line.
Referring now to the second part of my invention, and to Figs. 4 and 5 shew-
ing my improved take up motion for rotating the take up shaft,
number 27 denotes the take up shaft journalled in bearings in the
loom sides and having fast on one end thereof a spur
wheel 28
to which motion is imparted by a suitable system of speed gearing or train of
wheels or pinions 29 (one or more of which may he changeable) driven from a
short shaft 30 supported at the side of the loom in a bearing in the bracket 31
and receiving its motion through mechanism hereafter described, from a suitable
part of the lathe sword or going part, or from the centre 32, on which said
going part oscillates. The lever or arm 33 secured on the centre 32 moving
with the loom, and from which I preferably obtain the motion, is provided
with a screw 34 on which is a nut or block adapted when wing nut 35 is loosened
to be moved up or down said screw to alter the point of connection and the
throw of an adjustable connecting link or rod 36 attached to or forming part
of said nut or block. The opposite end of the adjustable connecting link 36 is
secured to a lever or arm 37 secured to one outer face of a hollow drum, barrel,
or sheath, 38 mounted loosely on the before-named short shaft 30. Within the
said drum and centred on studs 39 set at short distances apart and supported in
the sides thereof are a series of catches 40 which are forced by springs 41 against
the teeth of a ratchet wheel 42 located within the drum or sheath 38 and also
loosely mounted on the short shaft 30, the number of catches and their dis-
position within the hollow drum being such that some of said catches will always
engage with teeth on the ratchet wheel no matter how slight the movement may
be, and, therefore, while driving it, they also prevent any backward movement.
On the face of the ratchet wheel and integral therewith is a gear wheel 43 or it
may be one half of a clutch box while on a separate disc 44 secured by key on
the short shaft 30 is a similar opposing gear wheel 45, or half of a clutch box,
the disc 44 being also provided with recesses for holding spindles or fingers 46
on which are confined spiral springs 47. A hand wheel 48 secured by a sliding
key on the short shaft 30 is employed to turn the said shaft by hand, and a
nut 49 is applied to the screwed extremity of shaft 30. When said nut 49.is
screwed up tightly it forces the hand wheel 48, hollow drum 38, and ratchet
wheel 42, laterally on shaft 30 and places the gear or clutch 43 on said ratchet
wheel into engagement with the opposing gear or clutch 45 on the disc 44,
the springs on the spindles 46 serving to disengage said parts when the nut 49 is
unscrewed again. When the parts are in gear, the reciprocation by the loom
of the arm 37 fixed to the hollow drum or sheath 38 gives to said drum a rocking
or oscillatory motion which, through the catches or pawls 40 engaging some of
the teeth of the ratchet wheel 42 imparts to said ratchet wheel a step by step
progressive motion which is transmitted through the disc 44 to the short shaft 30
and thence through the speed gearing or train of pinions 29 and spur wheel. 28

page_text: to the take-up shaft 27 on which the whole of the take-up rolls or drums are
mounted and driven collectively thereby to take up the narrow ware being woven.
By unscrewing nut 49, the ratchet wheel 42, hollow drum 38, and hand wheel 48,
are forced laterally to the left and the gears or clutches 43 and 45 disengaged by
the pressure of the springs 47 against the heads of the spindles 46. The disc 44
is inclosed or encircled by a brake strap 50 hung or centred at one end on a
pin 51 secured to the loom side and adapted to be tightened or slackened around
said disc, to increase or reduce frictional resistance, by a screwed rod 52 screwed
into one end of the brake strap and provided with a spiral spring acting against
a collar or shoulder on said rod.
Referring to Figs. 6, 7, 8, and 9 and to the third part of my invention com-
prising improved independent supplementary mechanism applied to each indi-
vidual take-up roll or drum to admit of any such rolls or drums being revolved
forward or backward independently of the common take-up shaft as may be
necessary from time to time in case of a shuttle thread breaking or for any
other reason, number 27 is a portion of the common driven take-up shaft, on
which (in connection with each take-up roll) is loosely mounted a hand wheel 53
having an eccentric hub portion or boss 54. A shell 55 having a hub 55..is
secured on the take-up shaft 27 contiguous to the eccentric hub 54 of the hand
wheel 53 by a set screw or bolt 56 (see Fig. 6). The said shell 55 is provided
with external gear teeth 57 on the end adjacent to the eccentric hub 54 of the
hand wheel 53. 58 is the take up roll or drum and within the inner end thereof
is arranged what may be termed a combination gear rim 59 having a central
concentric opening into which extends the eccentric hub portion 54 on the hand
wheel 53.
The combination gear rim 59 has external gear teeth 60 on the periphery
thereof, the number of which is less than the number of teeth 58 in the drum 58
with which they are adapted to engage; and said combination gear rim has also
internal gear teeth 61 the number of which is greater than the teeth 57 on the
shell 55 and are adapted to engage therewith. The combination gear rim 59 is
made to turn freely on the eccentric hub or boss 54 of the hand wheel 53, and
the external and internal gear teeth 60 and 61 thereon are concentric with the
central opening in said gear rim. A collar 62 secured on the take-up shaft 27.by
a screw 63 holds the hand wheel 53 in place against the inner edge of the take-up
roll or drum 58 and the said take-up roll or drum in place on the shell, while an
internal annular flange 58b on the drum extends over the inner edge of the
periphery of the shell 55, (see Fig. 6).
The eccentricity of the hub portion or boss 54 of the hand wheel is approxi-
mately equal to the length of a tooth on the combination gear rim 59 plus any
additional amount for clearance (see Fig. 8).
The operation of the said supplementary and individual take-up mechanism is
as follows:-
When the take-up shaft 27 revolves in the ordinary operation of the loom,
as before described, the shell 55 fast thereon will revolve with it and will carry
the take-up roll or drum 58 and the hand wheel 53 through the combination
gear 59 loosely mounted on the eccentric portion 54 of the hand wheel 53.
When it is desired to cause any individual take-up roll or drum 58 to turn in
either direction independently of the take-up shaft 27 and while said shaft
continues to revolve, the hand wheel 53 to said take-up roll, being loose on the
shaft, is turned in one direction or the other according to whether it is desired
to turn the take-up roll or drum forward or back, and, in thus rotating said hand-
wheel, the eccentric hub portion 54 thereon revolves within the concentric central
opening in the combination gear or gear rim 59 and moves said gear or gear
rim so that the internal gear teeth 61 of same will be engaged continually with
the gear teeth 57 on the shell 55 through any movement of the hand wheel
and eccentric and it will be noticed that by one revolution of the hand wheel 53
and eccentric hub portion 54 all the gear teeth 57 on the shell 55 will have been

page_text: engaged by the internal gear teeth 61 on the combination gear rim 59 and if
there are one or more of said internal gear teeth 61 than there are gear teeth 57
on the shell 55 the movement of the combination gear 55 will be advanced beyond
its original position by the difference in the number of teeth between teeth 57
and 61. An operation of a similar nature will take place between the gear
teeth 58 on the drum or take-up roll 58 and the external gear teeth 60 on the
gear rim 59 during the same revolution of the hand wheel, 53, and there being
more teeth 58 than there are teeth 60, they will be advanced or moved forward
in the same direction around the latter teeth as the internal teeth 61 are advanced
around the teeth 57 and the movement of the take-up roll or drum 58 indepen-
dently of the take-up shaft 27, for one revolution of the hand wheel 53 and
eccentric hub portion 54 thereon will be approximately equal to the combined
movement or advancement of the gears 61 and 58 above referred to. The
continued revolution of the hand wheel 53 will cause the take-up roll or drum 58
to revolve on the shaft 27 to any extent desired either forward or backward.
When any force is applied to rotate the take-up roll or drum 58 on the take-up
shaft 27, without the aid of the hand wheel 53, the said drum, by reason of
the multiplying power of the hand wheel and also of the eccentric hub 54
thereon, will remain positively in any position given to it by the hand wheel so
that there will be no backward or forward movement apart from that given
through the take-up shaft.
I have described my individual supplementary take-up mechanism with
special reference to its use as a take-up for the take-up rolls or drums on a
narrow ware loom, but I do not limit myself to precisely this application of said
mechanism.
The details of construction of my improved motions may be varied somewhat
from what is shewn and described.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
(1) In looms for weaving ribbons, webbings, or other narrow ware, a dwell
gear shuttle motion comprising a train of gearing for transmitting motion from
the crank shaft or other suitable revolving part of the loom to a toothed gear
mounted loosely on a stud shaft and having a bevel or mitre wheel secured to
er formed integral with a slotted swinging arm centred on said stud shaft and
uscillated by a crank pin or stud adjustably secured to the intermediate or carrier
wheel of the train of gearing, a bevel wheel mounted loosely on a stud on the
swinging arm and gearing with the aforesaid bevel wheel and also with an
opposing loose bevel wheel likewise mounted loosely on the stud shaft and having
another bevel at the back thereof gearing with a bevel wheel fast on a short
shaft carrying the arm to which the swivel for the ordinary rack rod wire or cord
connections is attached, the bevel wheel on the swinging arm deriving constant
motion in one direction from the train of gearing and in one stroke of its
oscillatory motion driving through the intermediate gearing the short shaft for
actuating the rack rod wire connections and in the return stroke revolving
harmlessly in gear with the opposing gear wheel which thus remains stationary
whereby an intermittent motion is given to the short shaft substantially as and
for the purposes set forth.
1 (2) The combination with a dwell gear shuttle motion comprising essentially
a driven bevel wheel carried by a swinging arm operated and operating as
specified, of an internal fixed gear 22 concentric with the short shaft 17 an arm
or crank fast on said shaft and carrying a pinion or spur gear 23 meshing with
the internal gear and an arm 26 fast to said pinion or spur gear 23 and carrying
the swivel 20 to which the rack wire connections 19, 19, are attached, all sub-
stantially as and for the purposes set forth.
:
(3) In a loom, the take-up motion for rotating the take-up shaft to take up

page_text: the material or narrow ware as the weaving proceeds comprising a short shaft
suitably geared up to the take up shaft, a hollow shell, sheath, or barrel loosely
mounted on said short shaft and carrying thereon near to the internal walls of
same a series of catches or pawls forced by springs into engagement with a ratchet
