page_text: driving shaft to move and to stop the loom by means similar to those
described in a Patent granted to Erastus Brigham Bigelow, for “Im-
provements in Looms for Weaving," dated May 1867, and numbered
1269.
The reversing mechanism herein to be described is also similar in
some respects to that therein set forth, though its construction and the
mode of brining it into action constitutè important improvements.
The reversing mechanism consists of a roller p, an axle q, gears r and
8, a stud t, and a lever arm u, which carries the several parts just
indicated and is capable of oscillating on a stud v affixed to the loom
frame. A plan of this mechanism is given in Figure 5, and an elevation
of the side nearest the loom in Figure 6. The axis q revolves in a pipe
box w formed on the lever arm u, and carries the roller p and gear r
whilst the gear 8 is supported by the stud t, the object of the last-
mentioned gear being to change the direction of motion.
.
The reversing mechanism is so located with respect to the driving
shaft that when it is raised to a certain point, the gear s engages a gear
x affixed to the driving shaft, and the roller p presses against a roller y
affixed to the driving pulley, and so long as the two rollers are hield in
firm contact a reverse movement will be imparted to the loom, and when
they are separated that movement ceases and the reversing mechanism
becomes stationary until it is again brought into action. The pipe box
w before mentioned rests in a fork formed on the upper end of a vertical
bar z, which at its lower end is jointed to the horizontal arm of an elbow
lever a² which oscillates on a fixed stud 2, and has its depending arm
connected with the upright arm of a treadle lever c² by a rod d². The
treadle lever c² oscillates on a stud e² and is widened out at its forward
end to receive the foot of the weaver. When the weaver wishes to give
a reverse movement to the loom she with her foot presses down the
forward end of the treadle lever, which through the connections just
indicated raises the reversing mechanism and puts it in action; then
when she wishes the reverse movement to cease she removes her foot
from the treadle lever, and the reversing mechanism falls out of action
by its own weight.
The loom shinner is marked f³ and is capable of oscillating on the

page_text: from the lay of the loom its upper end plays in a slot has is usual, and
is forced forward to stop the loom by a spring 2.
The mode of applying the brake for arresting the movement of the
loom is as follows:-The brake, which is marked 1³, oscillates on a fixed
stud k³, and acts on a brake wheel on the driving shaft, as is usual...
It is brought into action, and released by a toggle joint arrangement
consisting of an elbow lever m², which oscillates on a fixed-stud n² and-a
link o³, which is jointed at its forward end to the brake, and at its rear
end to the horizontal arm of the elbow lever.
The depending arm of the elbow lever is connected by a rod p² with an
upright lever arm q² affixed to the shaft g³, so that when the shaft g² is
turned towards the front of the loom it presses the brake against the
brake wheel, and when it is turned in the opposite direction it withdraws
the brake from the brake wheel. The shaft is turned to bring the brake
into action by the shipper, and in order that the brake may be released
whilst the shipper is at rest, as is required to be done when the reversing
mechanism is brought into action, or when the loom is turned by hand,
the shipper is engaged and disengaged with the shaft as follows, viz. :—
The shipper has an arm * depending obliquely from it, to which a lock
lever is jointed, as represented in Figures 7 and 8. A spur projects
from the inner side of said lock lever, which by the pressure of a spring u²
locks into a notch va in an arm w³ affixed to the shaft g². The arm w³
and a releasing lever ³ now to be described are shown in Figure 9, with
the shipper removed. The releasing lever oscillates on a fixed stud y³,
and has a slot z² formed in its lower end, as represented in the Figure
just mentioned. A roller carried by a stud a³affixed_to_the_treadle-
lever c³ plays in said slot, and oscillates the releasing lever when the
treadle lever is oscillated.
When the upper arm of the releasing lever is moved forward a cam
surface b³ acts on the lower end of the lock lever 8, and withdraws the
spur from the notch ³, and thus disconnects the shipper from the
shaft, whilst the upper end of the releasing lever strikes a projection c³
on the arm to³, and turns the shaft a sufficient distance to withdraw the
break from the brake wheel. Now, suppose the loom to be thrown out
of gear, and the weaver desires to release the brake from the brake
wheel, and set the loom free, she presses the treadle lever down a certain
distance, and thereby disconnects the shipper, and releases the brake, as

page_text: just described, and if she wishes also to reverse the movement of the
loom she presses the treadle lever down still further, and thus brings the
reversing mechanism into action.
When the loom is suddenly stopped the recoil of the mechanism
furthest from the driving shaft is such as to sometimes displace some of
its parts, especially to disengage a pile wire from the withdrawing hook.
To prevent this effect I apply a brake to the shaft, which actuates the
wire operating mechanism, which acts simultaneously with the brake
applied to the driving shaft just described. In my application for a
Patent for "Improvements in Looms for Weaving Piled Fabrics,"
filed 5th August 1875, No. 2764, the Specification describes a wire
operating mechanism actuated by a shaft similar to the shaft g before
mentioned. To this shaft a whcel d³ is affixed, which serves as a brake
wheel, and carries the crank stud for operating the withdrawing hook.
On a fixed stud e³ a brake ƒ³ oscillates, which acts ou the wheel d³, and
is jointed at its inner end to a link 9³, which is jointed at its upper end
to a crank arm ½³ affixed to the shaft g². When the shaft is turned to
apply the brake to the driving shaft it at the same time brings the
brake into action, and when it is turned in the opposite direction it
releases both of the brakes simultaneously.
The mode of operating the lay of the loom, which has what is
technically called a "double beat" movement, may be understood as
follows:-The swords of the lay, which carry the race beam j", oscil-
late on studs ³, as is usual. On the rear sides of the swords lugs &³ are
formed, to which the forward ends of connecting bars m³ are respectively
jointed, whilst the rear ends of said connecting bars are jointed to the
ends of the lever arms n³, which are affixed to a shaft o³, which oscillates
in fixed bearings p³. From this description it will be seen that an oscil-
lating movement of the shaft will impart a vibratory movement to the
lay, and that when the lever arms are depressed, as represented in the
Drawings, they will put the lay in its backward position, and that when
they are clevated, so as to bring the axes of the several parts in a line,
they will put it in its forward position, and thus give the first beat, and
when the lever arms are elevated still further to a position indicated by
dotted lines in Figure 10, they will draw the lay back a correspondingly
short distance, and by their return movement give it the second beat,
thus giving to the lay two beats at each oscillation of the shaft.
Heretofore the required oscillating movement has been given to the

page_text: shaft by two cranks formed on a crank shaft located below the lever
arms, and respectively connected therewith by suitable connecting bars.
In my improved mode of operating the lay only one crank is required,
which being located outside of the loom frame is more accessable as
well as more simple in its construction than the double crank shaft
located inside the loom frame. It_may_be_understood as follows, viz.:
A crank wrist q³ is carried by the gear i before designated, and is con-
nected by a bar to a depending arm s³, which is affixed to the shaft o³.
It will be readily seen that by these means the crank wrist q³ will impart
one oscillation to the shaft o³ at each of its revolutions.
•

The mode of constructing and operating the shuttle binder will now
be described:-This part of my Invention has for its object to arrest the
shuttle at the termination of its movement without a shock, and to
relieve it from the bite of the binder before it is thrown. The means of
accomplishing this object consists in part in giving to the shuttle binder
somewhat the quality of a spring, and holding its swinging end rigidly
when the shuttle is completing its movement into the shuttle box, and
liberating it before the shuttle is thrown. Figure 11 is a plan, and
Figure 12 a rear view of the right-hand shuttle box, and Figure 13 is an
end view of the same on an enlarged scale. The shuttle race and the
front part of the shuttle box are constructed as usual. The shuttle binder
is marked t³, and has one end of it pivoted at u³ to the rear side of the
shuttle box v³, whilst the other end is capable of swinging a limited
distance towards and from the shuttle box. A spring presses it
towards the shuttle box and against the outer end of the part o³, to
which it is pivoted, which limits its movement in that direction. In the
-rear-of-the-shuttle-box an axis is-placed, which oscillates in bearings yª
affixed to the race beam. From the front side of the axis an adjustable
arm y projects, which engages another arm 23 projecting from the rear
side of the shuttle_binder when_the_shuttle enters. the shuttle box. From
the rear side of the axis a lever arm at extends with its end bent towards
the loom to bring it over a stationary cam surface 6* which acts upon it.
To stop the loom when a shuttle fails to enter the shuttle box the shuttle
binder acts on a lever arm c¹ affixed to the protecting rod d*, as is usual.
When a shuttle enters the shuttle box it strikes against the swelled part
of the shuttle binder, and when it has pushed it back a sufficient distance
to operate the protecting rod the arm strikes against the arm y®, and
rigidly holds the swinging end of the binder, whilst the spring action of

page_text: the binder gradually arrests the shuttle; then as the lay moves forward
to beat up the cloth the cam surface 6* elevates the arm a³, withdraws
the arm y from the arm, and thus liberates the binder and sets the
shuttle free preparatory to its being thrown. To enable the weaver to
release the shuttlo binder when the loom is at rest a handle et is affixed
to the axis ³, by which she may readily turn the axis.
The picking mechanism may be understood as follows:-A front view
of it as applied to the left-hand end of the loom is given in Figure 14,
and a plan thereof in Figure 15, with a section of the loom frame and
the lay. A balancing lever e' oscillates on a stud f* carried by the sword
of the lay, and has a weight g* formed on its inner arm, whilst to its
outer arm the lower end of the picker staff is pivoted. The upper end
of the staff traverses a slot in the race beam, and is maintained in a
proper horizontal plane whilst moving towards and from the cloth by a
link, as is usual. The object of the weight is not only to counter-
balance the weight of the picker staff and the arm of the lever to which
it is pivoted, but also to carry the picker staff, or assist in carrying the
picker staff back to the outer end of the shuttle box during the latter
part of its movement after it has thrown a shuttle. The weight of the
picker staff and of the lever arm to which it is pivoted when not
'counterbalanced absorbs to some extent the force of the picker staff in
throwing the shuttle after the picker staff has passed a vertical position.
The picking shaft j* oscillates in bearings * affixed to the loom frame,
and has an arm depending from it, which is connected by a strap m
to the picker staff. When the picking shaft is not in action it is held in
onc direction by the arm resting against the loom frame, as shown in
Figure 14, whilst it is free to turn in the opposite direction. An arm n
extends horizontally or nearly so from the picking shaft, against which
an arm on the cam shaft e strikes to throw the shuttle. From the above
description it will be seen that if the arm * was firmly affixed to the
picking, shaft the movement of the loom could not be reversed, as the
arm o¹ striking against the arm n' would arrest it. To overcome this
difficulty the arm n* is made capable of yielding under the action of a
coiled spring 2' in the direction in which the arm of moves when the
movement of the loom is reversed, and is made rigid in the opposite
direction by its resting against a fixed stop q' affixed to the picking
shaft. By limiting the movement of the picking shaft in one direction,
and making the arm n yielding, as above explained, the motion of the

page_text: loom may be reversed without withdrawing the shuttle from the shuttle
box.
"
The mode of operating the jacquard machine and of adjusting its
elevation relative to the loom will now be described. One object of this
part of my Invention is to facilitate the raising and depressing of the
jacquard machine to adjust the height of the harness cords as they are
contracted or extended_by_atmospheric-or-other-causes. The jacquard
machine may be constructed and the harness cords arranged as is usual.
The beams which support the mechanism on which it rests are marked s².
It is guided in its up-and-down movement by four guide stands affixed
to the beams just mentioned. In these stands suitable bearings are
formed in which two shafts u¹ turn, which carry at each of their outer
ends a cam v on which the feet of the machine rest. To the rear ends
of each of these shafts a screw gear 7 is affixed, and a horizontal
shaft to supported by bearings a carries two screws 3' which respectively
engage the screw gears. The cams * and the screws and screw gears
which turn the shaft that carry them are right and left handed in order
that the tendency of the weight of the jacquard machine to turn the
shaft may be counteracted. When the shaft w' is turned in one direction
it will raise the jacquard machine, and when it is turned in the opposite
direction will depress it. Heretofore the operator has turned the shaft w
for these purposes by a hand wheel affixed to it, which being considerably
above his reach when standing on the floor of the mill he is obliged to
ascend by steps or otherwise to a height at which he can reach it. To
obviate this inconvenience I combine with the mechanism just described
a depending shaft, to the lower end of which the hand wheel is affixed,
said depending-shaft being of sufficient length to bring the hand wheel
within easy reach of the operator when standing on the floor. The
|_hand-wheel-is marked and the depending shaft a³, which shaft is
supported by the stand affixed to the beam 8, and another stand D
affixed to the loom frame. The upper end of the shaft carries a bevil
gear which engages_a_bevil-gear-d-affixed to the shaft w%, and thus
transmits the motion of the shaft as to the shaft w*.
The trap board of the jacquard machine is marked es, and is connected
by bars f5 with lever arms go extending from a shaft * which oscillates
in bearings supported by the frame of the machine. The trap board is
elevated and depressed by oscillating the shaft ⁄ as is usual.
28

page_text: The means which I employ to oscillate it and to which this part of my
Invention relates may be understood as follows:-A cam j³ carried by
the shaft g before mentioned acts on a cam roller which is pivoted to
the lower end of an upright lever which oscillates on a fixed axis nº, and
at its upper end is connected with the depending arm of an elbow lever m³
by a horizontal rod n. The elbow lever m oscillates on an axis o³, whilst
a bar p³ connects its horizontal arm with a lever arm q³ extending from
and affixed to the shaft h³, the ends of the bar p³ being attached to their
respective arms by a ball-and-socket joint.
It will be seen that by connecting the upright lever, with the
depending arm of the elbow lever m³ on a horizontal or nearly horizontal
plane, the jacquard machine may be elevated and depressed, as above
explained, without the necessity of varying the length of the connecting
rod. Now suppose the trap board to be in its lowest position and the
cam roller resting against the part of the cam having the smallest
diameter, it will be obvious that as the cam moves forward and carries
the cam roller out to the part of the cam having the largest diameter it
will raise the trap board to its highest position, as is represented in the
Drawings, then as the cam continues its movement and the cam roller is
returning to its supposed position the trap board will descend by its own
gravity. The card cylinder, receives its reciprocating movement from
an oscillating shafts, and is drawn against the ends of the needles by a
weight on a- lever arm ³ as is usual. A bar v³ connects the lever
arm u with another lever arm to which oscillates on a stud at supported
by the frame of the jacquard machine. The lever arm w³ carries a
roller y which rests on the horizontal arm of an elbow lever 2º, as repre-
sented in Figure 16. The depending arm of the elbow lever is con-
nected by a horizontal rod a to the upper arm of an upright lever 6º,
which oscillates on the axis nº before mentioned, and carries a cam
roller c at its lower end, on which a cam de acts. The cam de raises the
weight and draws the card cylinder away from the needles in a manner
similar to that in which the cam ³ raises the trap board, as before
explained.
I will now describe the mode of operating the comber board. The
object of this part of my Invention is to diminish the motive power
required to drive the loom; to prevent the weight of that portion of the
jacquard harness which is, raised by the comber board from pushing the
loom forward when it descends, whereby the loom in that stage of its

page_text: -
operation may be more casily stopped; and also to form a more even
shed. Figure 17 is a sectional view of this part of the mechanism
looking towards the right-hand end of the loom. The comber board, as
is well known, is employed to raise the weights suspended from the
harness cords of the jacquard machine. It is marked e in the
Drawings, and is represented in its elevated position. The harness
cords pass from the jacquard machine down through the comber board,
and have weights suspended from them and knots formed on them by
which they are lifted by the comber board, as is usual; and as the
mounting of the jacquard harness cords is well known it is deemed
unnecessary to represent them in the Drawings. When the comber
board descends to its lowest position the harness cords are left suspended
from the jacquard machine, and made tenso by their respective weights;
then as the weights are raised by the comber board (acting on their
knots) their upper portion is slackened and hangs loosely. In order that
the trap board may properly trap the cords it is necessary that they
should be tense at the time the trapping operation takes place, conse-
quently at that time the comber board is made to descend below the
knots on which it acts, thus leaving the cords and weights suspended
from the jacquard machine. It will thus be seen that the weight of the
harness is alternately shifted from the jacquard machine to the comber
board, and vice versa, according as the comber board is elevated or
depressed. If under these conditions a counterbalance weight acting in
the direction of the motive power is applied to the comber board to
counterbalance the weight of the harness a shock to the mechanism will
be produced when the weight of the harness is shifted from the comber
board to the jacquard machine by the sudden change in the direction in
which the counterbalance weight will press on the cam which actuates
it. Instead therefore of applying the counterbalance weight so as to act
in the direction of the motive power I apply it so as to act in--the
opposite direction, whereby it presses on the cam constantly in one
direction, its size being sufficient to raise the comber board and the
barness.weights. connected with it. -A. shaft extends across the loom,
and oscillates in bearings jo affixed to the loom frame. From its rear
side two lever arms / extend, and carry the counterbalance weight_1.
For convenience-I-sometimes-place-this weight below the floor of the
mill, and support it by chains affixed to the upper side of the segments
of the lever arms. One of these lever arms is connected, by an adjustable
rod mi to a lever arm nº, which oscillates on a stud o affixed to the loom

page_text: frame, and carries a cam roller p' on which a cam 26 on the shaft e acts
to raise and depress the weight. From the front side of the shaft ♬ two
lever arms also extend, to the ends of which the lower ends of bars 8°
are respectively jointed, whilst the upper ends of said bars are similarly
jointed to stands to, which are affixed to the under side of the comber
board. These stands carry rollers 2, which traverse suitable grooves
in guide stands vº, and thus guide the comber board in its vertical
movements.
It will be obvious from this description that when the counterbalance
weight descends the comber board will be elevated, and when the counter-
balance weight is clevated the comber board will descend, that the
pressure of the counterbalance weight on the cam will always be in one
direction, and that by counterbalancing, the weight of the harness less
power will be required to drive the loom than when it is not counter-
balanced.
It will be obvious also that as the gravitating force of the counter-
balance weiglit is somewhat greater than that of the harness weights the
tendency of this arrangement will be to retard the loom rather than to
accelerate it when the harness weights descend, and that consequently
the movement of the loom can be more easily arrested when thrown out
of gear.
To aid in forming an even shed I put the comber board in an oblique
position when it is elevated, that is, raise its rear edge higher than its
front edge is raised, thus bringing the eyes of the jacquard harness
respectively to a line corresponding to the angle of the shed. This is
effected as follows:-Affixed to the stands before mentioned are
depending arms 20%, which carry rollers 2, which ply in grooves y
formed in guide stands 28 affixed obliquely to the loom frame. When
the comber board is elevated the rollers & will tip it in accordance with
the angle given to the guide stands, and when it is depressed they will
return it to its former position.
The mode of operating the heddle frames may be understood as
follows:-The object of this part of my Invention is to impart a more
positive and steady movement to the heddle frames than is imparted by
the usual strap connections. A sectional elevation of the heddle frames
and the mechanism which operates them, is given in Figure 21 looking

page_text: the mode in which the heads are affixed to the barrel. The barrel of
the beam is marked y' and its bearings 2', both parts being cast in one
piece with an interior cavity a³, as seen in Figure 20. The beam heads
are marked b³, and the shoulders on the barrel to which they are affixed cª
respectively. The heads us are screwed to the shoulders c8, as is shewn
in the Figure just referred to.
The part of my Invention which relates to the mode of constructing
and of operating the brake which holds the tension bar rigid at the time
the lay beats up the weft will now be described. It is especially
applicable to looms having a "double-beat" lay motion, such as is
herein-before described. The brake mechanism is represented in Figures
22 and 23, detached from the loom. In order that its application may
be more readily understood I will remark that the warp passes from the
warp beam around a guide rod over the tension bar through the heddles
to a "positive take-up "roller, as is usual, and as is indicatad in Figure 3,
The tension bar also under the force of a weight gives the required
tension to the warp and regulates its delivery as is usual. The tension
bar is marked d³ and oscillates on axes es supported by the loom frame.
To the right-hand axis a lever arm ƒ³ is affixed which terminates in the
form of a segment having a smooth face on which a brake lever 9³ acts.
The brake lever oscillates on a fixed stud ³, and is actuated by a toggle
joint arrangement, which consists of a lever arm that oscillates on a
fixed stud j and a link ³, the upper end of which is jointed to the
brake lever and the lower end to the lever arm. A connecting bar 7 has
its rear end also jointed to the lever arm, whilst its forward end is
pivoted to the depending arm 8³, which operates the lay as before
described. Hence it will be seen that when the depending arm puts
the lay in its backward position, in which it is represented in the
Drawings, it will push the brake lever away from the segment lever, as
shown in Figure 22, and leave the tension bar free; then when it moves
forward and gives the lay its first beat it brings the centres of the toggle
joint arrangement to a line, as shown in Figure 23, and presses the brake
lever against the segment lever and holds the tension bar rigid ; then as
it continues its movement to withdraw the lay preparatory to its second
beat, it will draw the toggle joint arrangement forward to the position
indicated by the dotted lines and release the brake, and when it returns
and gives the lay its second beat it will again bring the centres of the
toggle joint arrangement in a line, and apply the brake as before. Thus
