I, ALBERT DE LASKI, of 174 High Street, in the City of Boston, County of
Suffolk and State of Massachusetts, United States of America, Machinist, do hereby
declare the nature of this invention to be as follows :—
My invention relates to looms of the circular type designed to weave a tubular
fabric and particularly to such as are designed for the manufacture of hose for fire-
engine or other water-carrying service, for gas or steam service, or for analogous use.
The special purpose of my invention is to so improve the organization of looms of
the class mentioned as to secure simplicity of construction, steadiness, smoothness and
regularity of motion, strength of the various parts, and convenience and certainty of
operation, all to the end that a strong and closely-woven hose-tube or analogous fabric
may be rapidly and cheaply woven.
In carrying out the objects of my invention, I have substantially reorganized the
loom throughout, and I will now proceed to describe my improvements.
In describing the construction of my organized circular loom, I will begin at the
source of power, and explain the nature and relationship of the various groups of
mechanism, at the same time setting forth to a certain extent their operation and
cooperation with connecting parts, following the same through to the point of com-
pleting a web and discharging it from the machine, and subsequently briefly describe
the operation of the loom as a whole.
The frame of the machine comprises a suitable number of pillars arranged in a circle
and secured to a base plate, which pillars are aided in being firmly sustained in
vertical position, by braces.
A supporting frame carries all of the parts directly concerned in the production of
a web, which supporting frame rests upon, and is bolted to, the upper ends of pillars
and has directly secured thereto the brackets for supporting the shuttle track, brackets
for the heddles-guiding devices; brackets for supporting certain portions of the stop-
motion mechanism and warp-thread-guiding means; brackets for the warp spools and
warp tension means and an upper frame plate for supporting other parts of the loom
as hereinafter explained.

page_text: The driving shaft is supported in suitable bearings to which driving shaft is
rigidly fixed a pulley to be driven by the main-belt while another pulley receives the
belt connecting it with the pulley on the main shaft which is splined upon the main
shaft, so as to be longitudinally movable thereon, and is provided with a clutch part,
as hereinafter explained.
The main shaft is arranged longitudinally in bearings in the upper part of the
frame and is provided on its inner end with a bevel gear wheel constructed and
arranged to intermesh with and drive a bevel gear wheel provided with a downwardly
extending hub or sleeve by which it is secured to a sleeve adapted to turn or be
rotated on a second sleeve rigidly sustained by its upper end in the machine by a
bracket, so that as the main shaft is rotated it will, through the medium of bevel
wheels revolve or actuate all the parts connected with the sleeve.
The spools carrying the warp threads are arranged to turn in suitable bearings
formed in brackets. The warp threads are conducted from the spools through eyes in
a guide bar secured to an arm of a bracket and around tension drum secured at its
ends to a rod which rod is adapted to turn in suitable bearings formed in said arm of
said bracket whence the warp is threaded through the eyes of feeler pins connected
with the stop-motion mechanism and through the eyes of the heddles to the point on
the weaving pin where they are woven into the fabric.
An octagonally-shaped spider plate is supported on brackets extending up from
the circular top plate. The said spider plate is provided in its centre with an
aperture through which sleeves extend so as not to come into frictional contact there-
with. The spider plate is provided in its upper face with radial grooves to serve as
guide-ways for sliding blocks said slide blocks are provided with upwardly projecting
studs to which are secured, so as to turn thercon, anti-friction rollers or bowls which
rollers or bowls extend into a cam groove formed in the lower face of a cam plate
rigidly secured to and so as to turn with a sleeve.
Arms are pivotted at one end to the slide blocks and at their other ends to the outer
or upper ends of arms rigidly secured at their lower or opposite ends to a rock shaft
adapted to turn in suitable bearings formed in the upper ends of pillars extending up
from the upper circular plate. The rock shaft has an arm rigidly secured thereto at
each of its ends, and to each end of each arm are pivotted rods which latter are in
like manner connected with short sleeves or collars adapted to slide on rods and con-
nected with the heddle bars. An arm is connected at substantially its centre with the
rock shaft so that as said shaft is rocked by the movement in and out of the slide
blocks said arm will be oscillated and alternately raise and lower the different sets of
heddles so as to form the shed in the warps for the passage of the shuttle.
The construction whereby I am enabled to operate the leddles particularly with
respect to the radially grooved spider plate slide blocks and cam plate and their
features and adjuncts, I regard as an important feature of the invention.
To place the warp threads under the requisite tension and to keep the latter uniform
in degree under all circumstances, I pivot or otherwise fulcrum an arm on the upper
circular plate, one such arm for each spool and provide the outer free end of said arm
with a pad adapted to rest on the yarn or thread wound on the spool. A short rod
projecting up from the circular plate extends through the rear or inner end of the
arm and is provided on its upper end with a nut. A spiral spring is interposed
between the inner end of the said arm and the plate in such relation thereto as to
operate to press the end of said arm upward, and as a consequence the pad upon the
yarn or thread upon the spool.
As is well known and for reasons so well understood as not to be necessary to be
here explained, it requires less force or power to draw yarn off from a full bobbin,
offering any resistance to such operation, than a nearly empty one, and it is in like
way well understood that a spiral spring, will act with greater force when closely
compressed than when expanded to nearly its utmost limit. It therefore follows from
the construction and arrangement described that when the spool is full, and the spring
closely compressed, it will press the pad upon the yarn with its utmost force and that
as the spool becomes empty the spring will become relaxed, and press the pad with

page_text: lighter force upon the yarn or thread, thus making the power necessary to draw the
thread or yarn from the spool equal at all times.
The tension exerted on the yarn by the means just described, cannot advantageously
be made sufficient for successfully weaving such goods as my loom is particularly
designed to produce. To provide further tension on the warp yarns, the tension drum
around which said yarns are wound one or more times after passing through the eyes
of the guide bar is provided with a band wheel. A cord or band having one end
secured to an extension of the bracket supporting the tension rod is wound around
said band wheel and has its other end secured to a short rod extending up through a
hole in a plate or bracket on the upper end of bracket. A thumb screw or nut is
screwed on the lower end of said rod so as to regulate the force with which the band
is drawn around the wheel and as a resultant effect the force required to draw the
yarn wound around the tension rod from the spool, said band operating with
frictional effect on the wheel.
Rigidly to a sleeve loosely surrounding the revolving sleeve is a bevel gear wheel.
As said sleeve is connected by brackets or in any other suitable manner with the
stationary parts of the frame said bevel gear wheel is also held stationary. Below the
hub of the latter and between it and a collar fixed on the stationary sleeve is a rim
or collar secured to the revolving sleeve so as turn therewith said collar is provided
with short arms or extensions to which are secured by means of bolts and screws
or in any other suitable manner brackets carrying what I term the "shuttle
driving mechanism."
A shaft journalled in suitable bearings in said bracket is provided on its inner end
with a bevel pinion constructed and arranged to mesh with the bevel gear wheel
and at its opposite end, said shaft is provided with a gear wheel meshing with a
similar gear fixed on a short shaft having bearings formed in laterally extending
arms. A smooth or friction faced driving wheel is also secured to the shaft the
function of which latter wheel will be presently explained.
It will now be seen that as the revolving sleeve is revolved the collar and
bracket connected therewith will be carried around with it, and shaft will be revolved
by reason of the engagement of its attached bevel pinion with fixed gearing and as
a consequence the driving wheel will be also revolved.
:
The term shuttle in its general sense is meant to include substantially all of the
contrivances carrying the "filling" and passing through the shed and in its confined
sense said term is used to embrace simply.the frame carrying the parts operatively
connected therewith.
a stud
Journalled on suitable studs or pins connected with the shuttle frame are two sets
of wheels the former of which are arranged near the outer edge of the frame and
adapted to travel or inclined circular track plates and the latter arranged at a
suitable point inward toward the centre of the loom, and adapted to travel on other
inclined track plates said track-plates being secured to and supported by brackets
attached to the part of the frame. Journalled on a suitable stud of the shuttle frame,
near the outer rear edge thereof is a horizontally arranged wheel adapted to roll in
contact with, and bear against, the sides and within the circle described by a series of
pins closely arranged around the outer edge of the track-plate and on
depending from the outer end of an arm integrally connected with the shuttle frame
at its outer edge; and near its forward end is another horizontally arranged wheel
adapted to roll in contact with the outer sides, and without the circle of the pins.
Extending upwardly and rearwardly from the front face of the shuttle frame is an
arin to the free end of which, on a stud projecting therefrom, is journalled a friction-
wheel adapted to roll in contact with, and be driven by, a driving wheel, and in turn
to roll in contact with, and drive, the rear wheel of the shuttle or shuttle frame or
carriage. The force to drive the shuttle being applied near its rear outer corner,
there will be a tendency to press the shuttle at this point outward from the centre of
the machine, and the outer forward corner inward, hence the provision of wheels
operating on opposite sides of the circle of pins.

page_text: An arm extends down and curves outward and upward from a bracket for the
purpose of stopping the shuttle from shooting forward out of place, and out of control
of the shuttle driver when the latter is stopped. Each individual track-plate is
inclined and one is also inclined with respect to the other, that is to say, the face of
cach track plate is inclined, and the outer is placed at a lower horizontal plane than
the inner. This construction is important since it enables me to so operate the
heddles as to keep both sets of warp threads, in the formation of the shed, at all times
at the same angle and consequently under the same tension, and to utilize substantially
all of the space in the shed for the shuttle, permitting me to employ a spool or bobbin
of larger size than could otherwise be done, as will be understood, and the importance
of which will be appreciated by operators of looms of this type.
The means just described serve to support and guide the shuttle in its movements
when operated by the shuttle driving mechanism as has been indicated.
The weft or filling yarn or thread is wound upon a shuttle spool or bobbin and from
the latter the weft or filling is led over a rod or wire inward to and through a guide
eye to and back and forth through eyes or holes formed in a bar and beneath the end
of a tension spring secured to said bar, to and through an eye in what I term the
"batten shoe or follower curved to conform to the cylindrical form of the weaving
pin. By this batten shoe the filling is laid and pressed into the fabric, somewhat
analogous to the manner in which weft is beat up by a reed or lay in an ordinary
loom.
The batten shoe is provided with a guide eye through which eye the weft or filling
passes to its place between the warps on the weaving pin. This construction serves to
assist in guiding and steadying the weft, so that the batten shoe will act with
certainty thereon, and that it (the weft) will be laid in precisely proper position in the
fabric.
To insure the proper opening of the shed for the passage of the shuttle, and secure
the close insertion of the weft or filling and most effective operation of the batten
shoe, I provide the shuttle on its inner forward part with what I term a "spreader,"
formed of sheet metal and V-shaped in cross-section, and bulged outward or forward at
a point between the track plate and the weaving pin, and retreating rearwardly from
said point the inner edge or point of said spreader extending to or nearly to the
weaving pin, and being engaged by a forwardly extending rod or arm of the baiten
shoe which rod extends around within the spreader and is secured to the forward
inner portion of the shuttle frame or carrier. This rod and the brace rods or wires
connected at one end with the rear edge of the spreader and at the other with the
supporting arm of the batten shoe serve to support the said spreader in proper position
in the shed.
As will be supposed the weft or filling is laid up in the fabric under heavy tension
in order to secure a closely woven fabric; and to provide for this tension, in addition
to leading the weft in a zigzag course through the eyes in the tension bar which in
itself would place said weft under considerable stress or strain in drawing it from the
bobbin, I pivot a tension plate or spring on a stud projecting inward from near the
rear end of the tension bar and arrange said plate or spring so that its face toward
said tension bar will bear on the weft yarn threaded therethrough. I also provide
said tension bar with a screw-threaded stud which extends through the tension spring
or plate and has a thumb screw or nut turned thereon, by which means the force by
which the tension spring is made to bear on the weft or filling can be adjusted, and
the tension on said filling regulater.
To secure an even tension on the weft that is, to compensate for the variation in
tension occasioned by the variation in the angle at which the weft is drawn from the
bobbin or spool over the wire as the amount of yarn on the shuttle spool varies
substantially the same as has been explained with reference to the weft spools I journal
a rod in the shuttle frame, just forward or inward beyond the shuttle spool and secure
thereto an arm provided on the end, extending toward the shuttle spool with a pad
adapted to rest on the spool or bobbin and one end of a spiral spring coiled about a

page_text: stud projecting out from the frame is secured to a collar attached to a rod and operates
with a tendency to press said pad on the yarn on said spool or hobbin. As the yarn
on the spool is drawn off and said spool becomes empty, the tension of the spring
relaxes and the pad bears on the yarn on the spool with less force, thus compensating
for the increased force or power required to draw the yarn from the spool.
As an addition to the means just described, I may provide the shuttle frame on its
forward part with a dog pivotted to the frame, and adapted to have one arm or end to
bear on the extended core or journal of the spool or bobbin, and having its other end
or arm engaged by one end of a spring secured to the frame and operating with a
tendency to press the arm of the dog on said journal and by frictional contact there-
with retard its revolution. A cam is secured to the extended end of the rod and bears
upward on said spring with a tendency to cause the latter to so operate on the dog as
to force its arm or end with greater force against the journal of the bobbin or spool.
As the yarn on the spool is drawn off, and the rod is permitted to turn in the direction
by the operation of spring, as also of the pressure of the spring on cam said cam will
be turned to relieve the stress by which it causes the spring to act on the dog, the
form of said cam being such as to permit this operation. Consequently as the amount
of yarn on the spool decreases, the resistance to the turning of the spool, caused by
the frictional contact of the arm of the dog with its journal or axle.
In the event of the breakage or exhaustion of a weft or warp thread, I have
provided a construction whereby the weaving operations of the machine will be
automatically stopped as I will next proceed to explain.
A bevel gear is secured to the main shaft at any suitable point, but preferably near
or adjacent to the driving pulley. Said wheel meshes with a like bevel wheel secured
to the upper end of an upright shaft supported in suitable bearings formed in brackets
attached to the frame of the machine, which shaft is provided with another bevel gear
meshing with a similar gear secured on the outer end of a shaft horizontally arranged
in the machine and adapted to turn in bearings formed or supported therein.
A disc is provided having an elongated hub coarsely screw-threaded on its interior
and connected by this means with a coarse screw-thread formed on a shaft and
frictionally held thereon so as to turn therewith, excepting when opposed with con-
siderable force. A spiral spring is also provided having one end secured to a collar
rigidly secured to a shaft and the other end attached to the inner end of the said hub,
which latter has a groove formed around its entire circumference. Projecting
horizontally outward from the outer face of the disc are pins adapted to engage
pins arranged vertically in a hoop or ring, horizontally arranged in the machine, and
supported on pulleys which latter devices are arranged so as to turn on studs secured
in brackets of the frame.
The construction and arrangement of the parts last described hereinbefore is such
that as the upright shaft is revolved, it will, through the medium of gears revolve the
horizontal shaft and with it the disk held by frictional contact and by the stress of the
spring turn in unison therewith. The pins of the disc engaging the pins of the hoop
or ring will turn the latter on the pulleys, when, as has been said, no considerable
resistance is offered to the turning of disc. Should, however, obstruction be offered
to hold the hoop from being revolved, the revolution of disc will also be stopped
though the horizontal shaft will continue to revolve, the result of which will be to
screw the disc and its collar back on said shaft so as to disengage the pins and when
said rim is again permitted to revolve the tension of the spring will operate to screw
said disc and its attached hub back to its former and normal position, so as to bring
the pins into engagement with each other.
A lever is pivotted at a suitable point on a bracket provided at its upper end with a
pin or anti-friction roller journalled on a stud or pin and extending into the groove
of the elongated hub of the disc and resting against or loosely connected with a short
laterally extending arm of a latch lever pivotted to the frame and having a spring
connected therewith and with the frame at a suitable point outward from its fulcrum.
The outer end of said lever is supported in a suitable loop or guideway and is adapted
to be engaged and operated against the tension of the spring by the operator.

page_text: The inner end of lever is provided with a notch or hook adapted to engage or hook
over the upper end of a shipper lever pivotted or fulcrumed to a projection or ear on
the bracket of the frame, and guided at its upper end in a loop or way, while at its
lower end it is connected to the bow-portion of a U-shaped rod. This rod has the
inner ends of its arms connected to a yoke having a stud extending into a groove
formed in the outer circumference of the clutch part having a feather and groove
connection with the driving shaft that is splined thereon so as to turn therewith and
at the same time horizontally movable thereon, said clutch part is adapted to engage
with a clutch part constituting a portion of the hub of a pulley which is loose to turn
on the shaft when not in engagement with the other clutch part. Arms of the
U-shaped rod are guided in suitable ways formed in the bracket and spiral springs
surrounding said arms and arranged between one of their hearings and fixed collars
thereon, operate with a tendency to draw the U-shaped rod and clutch part with which
it is connected away from the other part so as to leave the pulley to turn freely on the
shaft without revolving the same.
As before explained, each warp thread is led from the tension device through an
eye formed in the inner end of a fecler pin which latter device is arranged so as to
slide in bearings formed in a small bracket secured to the lower face of a ring resting
on and secured to the upper ends of a bracket. Attached by one end to said feeler
pin is a spiral spring operating with a tendency to press said feeler pin outward so
that its outer end will engage with the vertical pins of the ring or hoop and stop its
revolution, as also the revolution of the disc which will effect the screwing inward of
said disc and its attached hub, and operate the lever all as hereinbefore explained, to
unlatch the shipper lever and stop the machine. The tension on warps is sufficient,
however, to hold said feeler pins inward out of engagement with the pins of the rim
or hoop, so that the machine may operate so long as the warps remain intact, and only
be stopped through the instrumentality of said feeler pins when a warp breaks or
runs out.
Another function of the feeler pins is to take up the slack in the warps as the
heddles operate to change the position of the warps to form the shed, their outer ends
being far enough distant from the pins to permit them to move for this latter purpose
without engaging or coming in contact with said pins. By this construction also the
feeler pins operate to take up any undue slackness of individual warps caused by
uneven winding of the same on the warp spools, and for the same reasons as those
explained should any individual warps become very slack, its feeler pin will operate
to stop the machine in the same manner as though such warp had been broken.
To effect a stoppage of the loom automatically when a weft or filling thread breaks,
I provide the mechanism which will next be described.
A rod is supported horizontally in bearings formed in a bracket and part of the
frame in such position with respect to the ring or hoop as to be moved outward into
engagement with, or inward to be disengaged from pins. A spiral spring surrounding
said rod and operating between a collar fixed thereto and the side of the frame tends
to press said spring outward as aforesaid. A spring latch is pivotted to the inner face
of the frame and is adapted to snap into a notch formed in the inner end of the rod
and so hold the same from engagement with the pins as aforesaid.
The tension bar is pivotted at its rear end, to lugs formed on the shuttle frame and
at its forward end it is loosely connected to the inner end of a rod suitably mounted
in bearings so as to slide therein and through the hollow axle of the forward wheel.
The construction and operation of the mechanism for taking up or drawing the
fabric from the weaving pin which is preferably formed as an integral part of a collar
is as follows.
A worm is formed on the lower end of the vertical shaft intermeshing with a worm
gear secured to the outer end of a horizontal shaft provided on its inner end with a
gear driving through the medium of an idle gear a large toothed gear on a shaft having
its bearings as have also wheels in a frame located directly underneath the weaving
pin. On the shaft is secured a toothed pinion gearing with another toothed pinion on
à shaft parallel with and in the same horizontal line with another shaft so that as the

page_text: worm shaft is revolved by the operation of worm and worm gear the train of gears
will be revolved.
Journalled in the upper end of an upwardly extending arm of the frame is a drum
or roller while directly below said drum or roller is another journalled on a shaft and
underneath the latter drum or roller are two devices of similar character affixed to
shafts with their peripheries rolling in contact. Farther down and on a shaft
journalled in one side of the frame is a guiding roller or drum. The surfaces of the
rollers may be roughened or otherwise frictioned while the peripheries of the rollers
affixed on shafts may be covered with any suitable yielding material.
As the fabric is woven around the weaving pin it passes down between rollers by
which it is flattened keeping the fabric from being twisted or turned on the weaving
pin as the tendency would be. The fabric thence passes between the rollers affixed on
shafts which rollers exert sufficient draught on the fabric to draw it off the weaving
pin, which draught since the fabric is woven with great tension around the pin is very
considerable. One roller is simply a guide roller over which the fabric passes after
being drawn off as before described.
To permit the rollers or drums on shafts to be operated by hand to draw off or take
up the fabric, I pivot a shipper lever to the frame and connect it above its fulcrum
point with a clutch part formed on a wheel splined on a shaft so as to be moved longi-
tudinally thereon a sufficient distance to disengage it from clutch part rigidly affixed
to said shaft. Arms are affixed to the clutch to permit the latter and the shaft to be
revolved when disconnected from the clutch part as aforesaid. A spring operates
between a collar on the end of a shaft and the hub of a wheel to move the latter and
its attached clutched part into engagement with clutch part when the operator releases
his hold.
The sleeve and weaving pin are made hollow so that the rubber lining for the hose
or other analogous article woven on the machine, or a wire rope or cable to be covered
or any other article around which it is desired to weave a fabric or cover, may be fed
through said sleeve and weaving pin and drawn off as the fabric is drawn off leaving
the latter as substantially woven about the former.
Though some of the devices or groups of devices have been described as though but
a single set or series is employed in the loom, it will be understood that as many series
or sets are used as are necessary to carry on the operation of weaving.

Improvements in Circular Looms.
ALBERT DE LASKI of 174 High Street, Boston, Suffolk, Massachusetts, United
States of America 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 :-
My invention relates to looms of the circular type designed to weave a tubular
fabric and particularly such as are designed for the manufacture of hose for fire
engine or other water carrying service, gas or steam service, or analogous use.

Similar letters of reference indicate similar parts in all the figures.
In describing the construction of my organized circular loom, I will begin at the
source of power, and explain the nature and relationship of the various groups of
mechanism, at the same time setting forth their operation and cooperation with
connecting parts, following the same through to the point of completing a web and
discharging it from the machine making particular reference to particular Figures
when necessary to facilitate an understanding of the case.
A represents the base plate of the frame of the machine comprising a suitable
number of pillars a, arranged on the line of a circle and secured to the base plate,
which pillars are aided in being firmly sustained in vertical position by braces a¹.
a, indicates the supporting frame, carrying all of the parts directly concerned in the
production of a web, which supporting frame rests upon and is bolted to the upper ends
of pillars a and have directly secured thereto the brackets a³, for supporting the shuttle
truck, brackets at, for the heddles-guiding devices; brackets a³, for supporting certain
portions of the stop-motion mechanism and warp-thread-guiding means; brackets a³,
for the warp spools and warp tension means; and upper frame plate a', for supporting
other parts of the loom, as hereinafter explained.
B indicates the driving shaft supported in suitable bearings provided in the bearings
or supports b, b, to which driving shaft is rigidly affixed the pulley b' to be driven by
the main belt, while the pulley, to receive the belt connecting it with the pulley 13
on the main shaft 6 is loose upon the main shaft B, so as to be longitudinally movable
thereon, and is provided with a clutch part, as hereinafter explained.
Main shaft is arranged longitudinally in bearings in the upper part of the frame,
and is provided on its inner end with a bevel gear c constructed and arranged to
intermesh with and drive bevel gear c¹ provided with a downwardly extending hub or
B

page_text: sleeve by which it is secured to a sleeve c², adapted to turn or be rotated on a sleeve c
rigidly sustained by its upper end in the machine by a bracket c' so that as main
shaft 6 is rotated it will, through the medium of bevil wheels c, c', revolve or actuate
all of the parts connected with sleeve c².
D indicates the spools carrying the warp threads, which spools are arranged to turn
in suitable bearings formed in the brackets aº. The warp threads W, are conducted
from the spools D, through eyes d, in tension and guide bar d¹ secured to an arm of
bracket a, around tension drum d² secured at its ends to a rod d, which rod is
adapted to turn in suitable bearings formed in said arm of said bracket (see particu-
larly Figures 15 and 16) whence the warp threads pass to the eyes of feeler pins d³,
connected with the stop motion mechanism, and through the eyes of the heddles d* to
the point on the weaving pin d³ where they are woven into the fabric.
By reference to Figures 15 it will be seen that guide and tension bar d¹ may be so
adjusted in its bearings or supports by means of nuts 2, 3, as to vary the angle that
the warp threads may have through the eyes d with reference to the line of draft
between the spools and said guide eyes and drum d² this construction being for the
purpose of adjusting the tension on the warps so as to insure the turning of said
drum as they are drawn off. If the warps are light, and the goods not very closely
woven the bar d' may be so adjusted as to have the guide eyes d as nearly as may be
on a line with the draft of the warps, and vice versa in case the warps are coarse and
laid up with the wefts under heavy tension.
In the example shown the tension bar d¹ is provided with thirty four guide
eyes d, so that number of warps may be led from the warp spools there-
through or a greater number of eyes may be provided for a greater number
of warps or the use of some dispensed with when a less number of warps is used, as
the size or character of the fabric to be woven may demand; and where the tube to
be produced is small, and but comparatively few warps are used to each warp-tension
mechanism a grooved wheel or pulley do, may be provided instead of the drum d²
for each warp thread, which wheel or pulley may be secured to rod das represented
in detail in Figure 15ª.
E represents the octagonally shaped spider plate supported on brackets
up from the circular top plate a'. Said spider plate is provided in its centre with
e, extending
an aperture e¹ through which the sleeves e², c³ extend so as not to come in frictional
contact therewith. The spider plate is provided in its upper face with radial grooves e²,
to serve as guide ways for the sliding blocks e³, shown most clearly in Figure 5.
Said slide blocks are provided with upwardly projecting studs e to which are secured,
so as to turn thereon antifriction rollers or bowls e" which rollers or bowls extend
into a cam groove formed in the lower face of a cam plate e rigidly secured to and
so as to turn with sleeve c².
It will be noticed that the relative arrangement of the spider plate E, and the
cam plate e, is such that the said cam plate will readily reciprocate the slides in
the grooves of the spider plate, but will at all times positively hold and maintain
said slides properly within the grooves. Such. a construction secures positiveness
and certainty of operation, and presents a compact and durable arrangement.
:
F represents arms pivotted at one end to slide blocks e3 and at their other ends
to the outer or upper ends of arms f, rigidly secured to their lower or opposite
ends to a rock-shaft adapted to turn in suitable bearings formed in the upper
ends of pillars f extending up from upper circular plate a Figure 6. Rock-
shaft has an arm rigidly secured thereto at each of its ends, and to each
end of each arm are pivotted one end of rods f which latter are in like
manner connected at their opposite ends with short sleeves or collars adapted to
slide on rods f and connected with the heddle bars Figures 6 and 7. Arm f³
is connected at substantially its centre with rock-shaft f, so that as said shaft is
rocked by the movement in and out of slide blocks e acting upon arms F, f,
said will be oscillated and alternately raise and lower the different sets of heddles
with which the opposite ends of arms are connected, so as to form the shed in the
warps for the passage of the shuttle.

page_text: The construction whereby I am enabled to operate the heddles, particularly with
respect to the radially grooved spider plate E, slide blocks e and cam plate e and
their features and adjuncts, I regard as an important feature of the invention.
By reference to Figure 3 it will be seen that of the eight sets of heddles represented
but two sets, one on each side of the machine, are in course of operation, while the
other six sets, three on one side and three on the opposite side, are at the extreme
limit of their movements three in one extreme position and three in the other, so that
the shed will be entirely open at these opposite points, fully enabling a shuttle and
other weft laying devices to operate at each of these points, and the position of the
warps to be changed there between.
To place the warp threads W under the requisite tension, to keep the latter uniform
in degree under all circumstances, I pivot or otherwise fnlcrum an arm G on the
upper circular plate, a one such arm for each spool D and provide the outer free end
of said arm with a pad g adapted to rest on the yarn or thread wound on the spool.
A short rod g projecting up from circular plate a extends through the rear or inner
end of arm G and is provided on its upper end with a nut ². A spiral spring g³ is
interposed between the inner end of arm G and plate a' in such relation thereto as to
operate to press said end of said arm upward, and as a consequence the pad g upon
the yarn or thread upon the spool D. As is well known, and for reasons so well
understood as not to be necessary to be here explained, it requires less force or power
to draw yarn off from a full bobbin, offering any resistence to such operation, than a
nearly empty one; and it is in like way well understood that a spiral spring, such as
is indicated by g³ will act with greater force when closely compressed than when
expanded to nearly its utmost limit. It therefore follows from the construction and
arrangement of parts shown, that when the spool D is full, and spring g³ is closely
compressed, it will press pad y upon the yarn with quite its utmost force and that as
the spool becomes empty spring g³ will become relaxed, and press the pad with lighter
force upon the yarn or thread, thus making the power necessary to draw the thread
or yarn from the spool equal at all times.
The tension exerted on the yarn by the means just described, cannot advantageously
be made sufficient for successfully weaving such goods as my loom is particularly
designed to produce. To provide further tension on the warp yarns, the tension
drum d², around which said yarns are wound one or more times after passing through
the eyes d of guide bar d', is provided with a band wheel g, as shown most clearly in
Figures 1, 15 and 16, A cord or band g³, having one end secured to an extension, gº,
of the bracket supporting the tension drum d², is wound around said band wheel g
and has its other end secured to a short rod 97, extending up through a hole in a plate
or bracket on the upper end of bracket a³. A thumb saw or nut is screwed on the
lower end of said rod g' so as to regulate the force with which the band g is drawn
around wheel g*, and as a resultant effect, the force required to draw the yarn wound
around the tension drum d from the spool D, said band g³ operating with frictional
effect on wheel g*.
Rigidly secured to a sleeve H loosely surrounding revolving sleeve c² is a bevel
gear wheel h. As said sleeve is connected by brackets ¹, or in any other suitable
manner with the stationary parts of the frame, said wheel is also held stationary.
Below the hub of wheel hand between it and a collar ² fixed on stationary sleeve c³
is a rim or collar ³, secured to revolving sleeve e² so as to turn therewith. Said
collar ³ is provided with short arms or extensions h', to which are secured by means
of bolts and screws, or in any other suitable manner, the brackets I, carrying what I
term the "shuttle driving mechanism."
A shaft i journalled in suitable bearings in said bracket I is provided on its inner
end with a bevel pinion, constructed and arranged to mesh with bevel gear h, and
at its opposite end, said shaft i is provided with a gear wheel meshing with a
similar gear, fixed on a short shaft having bearings formed in laterally extending
arms, of bracket I, as seen in Figures 8 and 12. A smooth or friction faced driving
wheel is also secured to shaft i just inside of the point at which wheel is secured
thereto, the function of which latter wheel will be presently explained.

page_text: It will now be seen that as sleeve c² is revolved collar ³ and bracket I connected
therewith will be carried around with it, and shaft I will be revolved by reason of
the engagement of its attached bevel pinion i, with fixed gear h, and as a consequence
driving wheel will be also revolved through the medium of gears 12, 13.
The arrangement of shuttle driving frames and shuttle driving devices as above
explained insures a compact and simple arrangement of the parts, since the shuttle
driving frame is supported directly at the centre of the machine, in a convenient
position for effective operation.
and
J represents the shuttles by which term, in its general sense, it is meant to include
substantially all of the contrivances carrying the "fillings" and passing through the 1
shed; and in its confined sense said term is used to embrace simply the frame carrying
the parts operatively connected therewith. Journalled on suitable studs or pins
connected with the shuttle frame, are wheels, j,,,, the former arranged near the
outer edge of the frame and adapted to travel on inclined circular track plates j²,
the latter arranged at a suitable point inward toward the centre of the loom, and
adapted to travel on inclined track plates j³, said track plates being secured to and
supported by brackets a³ attached to the part a² of the frame. Journalled on a suitable
frame stud of the shuttle frame, near the outer edge thereof is a horizontally
arranged wheel j, adapted to roll in contact with and bear against the sides and
within the circle described by a series of pins j³ closely arranged around the outer
edge of track plate 2; and on a stud depending from the outer end of an arm ja
integrally connected with the shuttle frame at its outer edge and near its forward
end is another horizontally arranged wheel, adapted to roll in contact with the outer
sides, and without the circle of the pins . Extending upwardly and rearwardly from
the front face of the shuttle frame is an arm 8, to the free end of which on a stud
projecting therefrom is journalled a friction wheel adapted to roll in contact with
and be driven by driving wheel and in turn to roll in contact with and drive rear
wheel of the shuttle or shuttle frame or carriage. The force to drive the shuttle
being applied near its rear outer corner there will be a tendency to press the shuttle
at this point outward from the centre of the machine, and the outward forward corner
inward, hence the provision of wheels and j' operating on opposite sides of the circle
of pins j³.
10 represents an arm extending down and curving outward and upward from the
bracket I, for the purpose of stopping the shuttle from shooting forward out of place
and out of control of the shuttle driver when the latter is stopped. As shown, not
only is each individual track plate inclined, but one is inclined with respect to the
other, that is to say, the face of each track plate is inclined, and the outer j², is placed
at a lower horizontal plane than the inner, j³. This construction is important since it
enables me to so operate the heddles as to keep both sets of warp threads, in the
formation of the shed, at all times at the same angle, and consequently under the same
tension, and to utilize substantially all of the space in the shed for the shuttle, per-
mitting me to employ a spool or bobbin of larger size than could otherwise be done,
as will be understood, and the importance of which will be appreciated by operators
of looms of this type.
The means just described serve to support and guide the shuttle in its movements
when operated by the shuttle driving mechanism, all as has been so clearly indicated
in the explanation of the arrangement and relationship of parts as to need no further
description.
K indicates the shuttle spool or bobbin on which the weft or filling yarn or
thread W1, is wound, and from which spool or bobbin the weft or filling Wis led
over a rod or wire k, inward to and through a guide eye k¹, to and back and forth
through eyes or holes formed in a bar ², and beneath the end of a tension spring
secured to said bar, to and through an eye in what I term the "batten shoe
follower k³, curved to conform to the cylindrical form of the weaving pin, by which
batten shoe the filling is laid and pressed into the fabric, somewhat analogous to the
manner in which weft is beat up by a reed or lay in an ordinary loom.
"
or
It is to be noticed also that the batten shoe k³ is provided with a guide eye, k"

page_text: hown by dotted lines in Figure 10, through which eye the weft or filling W passes
o its place between the warps on the weaving pin d³. This construction serves to
ssist in guiding and steadying the weft, so that the batten shoe will act with certainty
hereon, and that it (the weft) will be laid in precisely proper position in the fabric.
To insure the proper opening of the shed for the passage of the shuttle, and secure the
close insertion of the weft or filling and most effective operation of the batten shoe, I
provide the shuttle on its inner forward part, with what I term a spreader "L
formed of sheet metal and V shaped in cross-section, as represented in Figure 11 and
bulged out or forward as at l, a point between track plate 3 and the weaving pin, as
viewed from above, and retreating rearwardly from said point 1, the inner edge or
point, of said spreader extending to or nearly to the weaving pin, and being engaged
by a forwardly extending rod or arm, of the batten shoe 3, which rod extends
around within the spreader and is secured at 13 to the forward inner portion of the
shuttle frame or carrier. This rod and the brace rods or wires l, connected at one
end with the rear edge of the spreader L, and at the other with the supporting arm 15,
of the batten shoe ³ serve to support the said spreader in proper position in the shed.
The rods are so disposed as to internally reinforce the spreader along its entire
convergent position and said rod in conjunction with the rod 1, forms a skeleton form
upon which the sheet metal spreader is mounted. Such a construction enables the
spreader to be formed of sheet metal which admits of the warp threads being supported
throughout the transverse width of the spreader end reduces liability of engagement
or entanglement with the warp threads, as might be the case where any portion of the
threads within the dimension of the spreader, was left unsupported.
The rod is connected with the batten shoe adjacent to the forward end of the
spreader, thus insuring the warp threads, a direct passage from the batten shoe' on to
the spreader. The curved form of the batten shoe ensures its carrying the warp threads
intimately near the weaving pin for a considerable distance around the circumference
of the weaving pin, so as to properly guide them on to the spreader while the curved
form of said shoe enables the filling to be properly laid and pressed up into the fabric.
As will be supposed, the weft or filling Wis laid up in the fabric under heavy
tension in order to secure a closely woven fabric, and to provide for this tension, in
addition to leading the weft in a zig-zag course through the eyes in the tension bar k²,
which in itself would place said weft under considerable stress or strain in drawing it
from the bobbin. I pivot a tension plate or spring M, on a stud m, projecting inward
from near the rear end of tension bar and arrange said plate or spring so that its
face toward said tension bar will bear on the weft yarn threaded therethrough, as
shown in Figure 10. I also provide said tension bar with a screw-threaded stud m¹
which extends through the tension spring or plate M, and has a thumb screw or nut, m²
turned thereon, by which means the force by which the tension spring is made to bear
on the weft or filling W' can be adjusted, and the tension on said filling regulated.
To secure an even tension on the weft, that is, to compensate for the
variation in tension occasioned by the variation in the angle at which the
weft is drawn from the bobbin or spool K over the wire k, as the amount
of yarn on the shuttle spool K varies, 'substantially the same as has been explained
with reference to the warp spools D. I journal a rod N, in the shuttle frame,
just forward of or inward beyond the shuttle spool and secure thereto an arm n,
provided on the end extending toward the shuttle spool with a pad n¹ adapted to rest
on the spool or bobbin K, and one end of a spiral spring n², coiled about a stud n³,
projecting out from the frame is secured to a collar n attached to rod N and operates
with a tendency to press said pad n' on the yarn on said spool or bobbin K. As the
yarn on the spool K is drawn off and said spool becomes empty the tension of spring n²
releases and pad n¹ bears on the yarn on the spool with less force, thus compensating
for the increased force or power required to draw the yarn from the spool.
As an addition to the means just described, I may provide and in most instances
prefer to construct the machine with the form of means represented in Figure 17:
that is, I provide the shuttle frame on its forward part with a dog O, pivotted at o to
the frame and adapted to have one arm or end of to bear on the extended core or

page_text: journal o of the spool or bobbin K, and having its other end or arm o³, engaged by
one end of a spring of, secured to the frame and operating with a tendency to press
the arm o of the dog O on the said journal o and by frictional contact therewith
retard its revolution. A cam o' is secured to the extended end of rod N and bears
upward on said spring of with a tendency to cause the latter to so operate on dog O
as to force its arm or end o¹ with greater force against the journal o² of the bobbin or
spool K. As the yarn on the spool K is drawn off, and rod N is permitted to turn
in the direction of the arrow (Figure 17) by the operation of spring n² (Figure 10) as
also the pressure of spring of on cam o said cam will be turned to relieve the stress by
which it causes spring of to act on dog O the form of said cam being such as to permit
this operation, consequently as the amount of yarn on the spool K decreases, the
resistance to the turning of the spool, caused by the frictional contact of arm o of
dog O with its journal or axle, will also decrease.
In the event of the breakage or exhaustion of a weft or warp thread, I have provided
a construction whereby the weaving operations of the machine will be automatically
stopped as I will next proceed to explain.
P represents a bevel gear secured to the main shaft 6, at any suitable point, but
preferably near adjacent to driving pulley b³, as seen in Figure 2.
Said wheel P meshes with a like bevel wheel p secured to the upper end of an
upright shaft p', supported in suitable bearings formed in brackets attached to the
frame of the machine, which shaft p₁ is provided at a point below wheel P with another
bevel gear, meshing with a similar gear p³, secured on the outer end of a shaft p
horizontally arranged in the machine and adapted to turn in bearings formed or
supported therein (see Figures 1, 2 and 18).
Qrepresents a disc having an elongated hub q, coarsely screw-threaded on its
interior and connected by this means with a coarse screw-thread g₁ formed on the
shaft p and frictionally held thereon so as to turn therewith, excepting when opposed
with considerable resistant force. q represents a spiral spring, having one end
secured to a collar q³, rigidly secured to shaft p* and the other end attached to the
inner end of hub q, which latter has a groove, formed around its entire circumference,
all as clearly shown in Figures 18 and 19.
Projecting horizontally outward from the outer face of disc Q are pins q³, adapted
to engage the pins r, arranged vertically in a hoop or ring R, horizontally arranged
in the machine, and supported on pulleys which latter devices are arranged so as to
turn on studs secured in the brackets a' of the frame.
of
The construction and arrangement of the parts last described hereinbefore is
such that, as shaft p' is revolved it will, through the medium of gears p², p³
revolve shaft p₁ and with its disc Q held by frictional contact and by the stress of
spring to turn in unison therewith, and the pins q³ of disc Q engaging pins
hoop or ring R will turn the latter on pulleys, when as has been said, no considerable
resistance is offered to the turning of disc Q. Should, however, obstruction be offered
to hold hoop R from being revolved, the revolution of dise Q will also be stopped,
though shaft p will continue to revolve, the result of which will be to screw disc Q
and its collar back on said shaft p* so as to disengage pins q³ from pins r, and when
said rim R is again permitted to revolve the tension of spring q² will operate to screw
said disc and its attached hub back to its former and normal position so as to bring
pins and into engagement with each other all as will be clearly understood by
those skilled in the art upon an inspection of the figures of the drawing last herein-
before mentioned.
S represents a lever pivotted at s at a suitable point on the bracket a³, provided at
its upper end with a pin or antifriction roller journalled on a stud or pin, and extending
into the groove q of the elongated hub of disc Q (Figure 18) and resting against or
loosely connected with a short laterally extending arm s¹, of a latch lever pivoted
to the frame at så and having a spring connected therewith and with the frame at a
suitable point outward from its fulcrum; which spring operates with a tendency to
throw the end of said lever in the direction of the arrows pictured in Figures 20
and 21. The outer end, s of said lever is supported in a suitable loop or guideway 7,

page_text: and is adapted to be engaged and operated against the tension of spring by the
operator.
The inner end of lever s² is provided with a hook or notch, s8, adapted to engage or
hook over the upper end of a shipper lever T, pivotted or fulcrumed at f to a projection
or ear on the bracket b of the frame, and guided at its upper end in a loop or way th
while at its lower end it is connected to the bow portion of a U shaped rod (see
Figure 22) having the inner ends of its arms (2, t², connected to a yoke to having a
stud,, extending into a groove formed in the outer circumference of the clutch
part t, having a feather and groove connection with the driving shaft B that is,
splined thereon so as to turn therewith and at the same time be longitudinally movable
thereon. Said clutch part t is adapted to engage with the clutch part to, constituting
a portion of the hub of pulley which is loose to turn on shaft B when not in engage-
ment with the clutch part to. Arms of the U shaped rod are guided in suitable
ways formed in the bracket b and spiral springs t₁t surrounding said arms and
arranged between one of their bearings and fixed collars t, t thereon, operate with a
tendency to draw the U shaped rod and clutch part with which it is connected
away from clutch part t so as to leave pulley 62 to turn freely on shaft B without
revolving the same.
It will now be understood that if the upper end of lever T were mooved outward
in the direction of the arrow (Figure 18) its lower end would be moved in the reverse
direction or opposite to the stress or force exerted by spring t' forcing clutch part t
into engagement with clutch part to causing pulley 62 to be turned with driving shaft B
and putting the machine into operation; at the same time the upper end of said
lever T would be caught behind the hook s of lever s², and be held in that position,
as represented in Figure 20. Should however, lever be moved to the position
represented in Figure 21, either by operating said lever by hand, or automatically
through the medium of lever S, as hereinafter explained, springs 7 acting on the
U shaped rod will disengage clutch part to from clutch part to leaving pulley 6² to
turn with freedom on shaft B, and the machine to stop.
As before explained each warp thread is led from the tension device through an eye
formed in the inner end of a feeler pin d³ which latter device is arranged so as to slide
in bearings formed in a small bracket V, secured to the lower face of a ring U, resting
on and secured to the upper ends of brackets a³. Attached by one end to said feeler
pin d³ at a point between its bearings, and having its other end resting against one of
said bearings is a spiral spring ¹, operating with a tendency to press said feeler pin
outward (as indicated by the arrow Figure 6) so that its outer end will engage with
the vertical pins r of ring or hoop R and stop its revolution, as also the revolution,
of disc which will effect the screwing inward of said disc and its attached hub and
operate lever S, all as hereinbefore explained, to unlatch shipper lever T and stop the
machine. The tension on warps W is sufficient, however, to hold said feeler pins
inward, out of engagement with the pins r of rim or hoop R, so that the machine may
operate so long as the warps remain intact, and be stopped through the instrumentality
of said feeler pins d³ when a warp breaks or runs out.
Another function of the feeler pins is to take up the slack in the warps as the
heddles operate to change the position of the warps to form the shed, their outer ends
being far enough distant from the pins to permit them to move for this latter purpose
without engaging or coming in contact with said pins. By this construction also the
feeler pins operate to take up any undue slackness of individual warps caused by
uneven winding of the same on the warp spools, and for the same reasons as those
explained should any individual warps become very slack, its feeler pin will operate
to stop the machine in the same manner as though such warp has been broken.
To effect a stoppage of the loom automatically when a weft or filling thread W
breaks I provide the mechanism which will next be described.
✗ represents a rod (see Figure 1) supported horizontally in bearings formed in the
brackets a and part a² of the frame, in such position with respect to ring or hoop R
as to be moved outward into engagement with, or inward to be disengaged from pins
A spiral spring a, surrounding said rod X and operating between a collar fixed
r.

page_text: thereto and the side of the frame, tends to press said rod outward as aforesaid. A
spring latch 2 is pivotted to the inner face of the frame a², and is adapted to snap
into a notch formed in the inner end of rod X and so hold the same from engagement
with pins r, as aforesaid.
As shown in Figure 10, tension bar is pivotted at its rear end, as at 3 to lugs
formed on the shuttle frame, and at its forward end it is loosely connected to the inner
end of a rod, 4, suitably mounted in bearings so as to slide therein and through the
hollow axle, of the forward wheel j. The construction and relationship of the parts
just described is such that the tension on the weft yarn, as it is drawn from the shuttle
will hold the forward end of bar k, inward, and consequently maintain rod in the
same position, as represented in figure 10, but should said weft thread break, spring a
operating on rod a will move said rod outward so that its outward end will in its
movement come in contact with the free end of latch, and move it so as to unlock it
from rod X and permit spring a to move the latter into engagement with the pins
or ring or hoop R and by said ring through the medium of the adjuncts, as before
explained, operate the shipper lever to stop the machine.

The construction and operation of the mechanism for taking up or drawing the
fabric from the weaving pin d³, which is preferably formed as an integral part of
the collar will next be explained.
Y represents a worm formed on the lower end of vertical shaft p², intermeshing
with a worm gear y, secured to the outer end of a horizontal shaft y, provided on its
inner end with a gear y², driving, through the medium of idle gear 3,
a large toothed
gear y, on a shaft, having its bearings, as have also wheels y2 y3, in a frame Z
located directly underneath weaving pin ds. On the end shaft y opposite that at
which wheel is secured is, a toothed pinion y gearing with another toothed
piniony, on a shaft ys, parallel, with and in the same horizontal line with shaft y', so
that as shaft y' is revolved by the operation of worm Y and worm gear y, the train
of gears yyy and y' will be revolved.
Journalled in the upper end of an upwardly extending arm, of frame Z on a
shaft ¹, is a drum or roller 2, while directly below said drum or roller is another 3,
journalled on a shaft 4, and underneath the latter drum or roller are two devices
of similar character (not lettered being hidden by gear wheels y y') affixed to
shafts yy, with their peripheries rolling in contact with each other, and farther
down and on a shaft journalled in one side of the frame is a guiding roller or drum 2ª.
The surfaces of the rollers may be roughened or otherwise frictioned while the
peripheries of the rollers affixed on shafts y y may be covered with any suitable
yielding material.
As the fabric is woven around weaving pin dit passes down between rollers ² z³
by which it is flattened, as shown in figure 25, keeping the fabric from being twisted
or turned on the weaving pin, as the tendency would be. From rollers the fabric
passes between the rollers on shafts y ys, which exerts sufficient draught thereon to
draw it off the weaving pin, which draught since the fabric is woven with great
tension around the pin, is very considerable. Roller is simply a guide roller over
which the fabric passes after being drawn off as before described.
To permit the rollers or drums on shafts y ya to be operated by hand to draw off
or take up the fabric, I pivot a shipper lever, , to the frame Z and connect it above
its fulcrum point with a clutch part 7, formed on the hub of wheel y', said wheel
being splined on shaft y so as to be moved longitudinally thereon, a sufficient
Arms 2, are
distance to disengage it from clutch part rigidly affixed to said shaft.
affixed to clutch part to permit the latter and shaft y' to be revolved when dis-
connected from clutch part 2, as aforesaid. Spring, operates between a collar on
the end of shaft y' and the hub of wheel y to move the latter and its attached clutch
part into engagement with clutch part when the operator releases his hold on
lever zº.

The operation of the loom has been so far set forth in the description of its
construction and the relationship and operation of its various parts as to leave little
or nothing more to be explained. It is to be noticed, however, that as the loom is

page_text: here represented, it is organized to be operated with two shuttles, and appliances
connected with each for laying its weft thread up into the fabric, one shuttle being
arranged substantially at the point where the slide blocks e³ are moved farthest toward
the periphery of the spider plate, and the other at the point where said slide blocks
are drawn back to their innermost limit in the opposite direction. These points of
arrangement of the shuttles are those at which the shed is opened to its utmost limit,
and the points there between are those at which the two sets of warp change position
by the operation of the heddles, as herein-before explained.
.
The sleeve c³ and weaving pin d' are made hollow so that the rubber lining for the
hose or other analogous article woven on the machine, or a wire, rope, or cable to be
covered, or any other article around which it is desired to weave a fabric or cover,
may be fed through said sleeve and weaving pin and drawn off leaving the latter as
substantially woven about the former.
Though some of the devices or groups of devices have been described as though
but a single set or series are employed in the loon, it will be understood that as many
series or sets are used as are necessary to carry on the operation of weaving.
Having now particularly described and ascertained the nature of the said invention,
and in what manner the same is to be performed, I declare that what I claim is :-
First. The frame, a stationary spider plate E, provided with radial grooves e²,
supported by the frame, slide c³, for operating the heddles arranged in the grooves of
the spider plate, and an inverted rotary cain es, adapted to engage said slides to
reciprocate them in the grooves of the spider plate, and at the same time positively
hold them therein, substantially as set forth.
Second. The frame, a rotary main shaft, a spider plate E, provided with radial
grooves e² supported by the frame, a stationary sleeve also supported by the frame, a
sleeve surrounding and adapted to turn on said stationary sleeve, a gear secured to
said revoluble sleeve, a gear on the main shaft intermeshing with said first mentioned
gear, slides e³, for operating the heddles, arranged in the radial grooves e² of the spider
plate, an inverted cam e, secured to and adapted to be rotated by said revoluble
sleeve and engaging with said slides to operate them and at the same time positively
hold them in their grooves, substantially as set forth.
Third. The frame, the radially grooved stationary spider plate supported thereby,
the slides adapted to operate in said grooves, a rotary cam engaging and operating
said slides, rock shafts having bearings in the frame, arms secured to said rock shafts,
other arms connecting the slides with the first mentioned arms, rocker arms, also
secured to the rock shafts, the beddle bars supported and guided in the frame, and
rods connecting heddle bars with said rocker arms, all arranged combined and
operating substantially as and for the purposes herein before set forth.
Fourth. The frame, radially grooved stationary spider plate supported thereby, the
slides adapted to operate in said grooves, a rotary cam engaging and operating said
slides, rock shafts having bearings in the frame, arms F, f., rods f*, the heddle
bars and heddles, collars f forming a part of the heddle bars, and rods forming
guides for the heddle bars, all combined and operating as and for the purpose herein-
after set forth.
