We, WILLIAM BELL WHITE, Junior, and WILLIAM BELL WHITE, Senior, of Red Scar
Spring Works, Colne, in the County of Lancaster, Machinists, 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 :-
The first part of this invention relates to a new construction of shuttle pegs. As
ordinarily constructed shuttle pegs are forged by hand or foot hammers or machines.
In this process, the iron or steel is got too hot or worked too cold under the
hammers above named, which cause them to break in the shuttle when in use.
This part of our invention is to overcome this objection, and furthermore to obtain
a longer peg head whereby the peg or shank is steadied when working in the
shuttle.
In proceeding to carry out our invention, we make a loose metal peg head, trough
shaped. This may be of cast metal but is preferably made from sheet metal
blocked to shape. Its appearance is well illustrated in Fig. 1, Sheet 1, of the
accompanying drawings. This grooved head or hollow channel enables us to make a
loose wire peg body or shank from cold drawn wire or other metal preferably steel
being un-burnt, and solid, and not being forged by hammers, it still retains its
solidity and its toughness, hence it is very durable.
That portion of the wire body which is intended to fit in the trough or peg head.
is bent or doubled over. Fig. 2 represents the wire body for the formation of the
peg shank doubled over at A, and pierced with two holes B C. The trough shaped
peg head (Fig. 1) is also pierced with two holes D E. A rivet is passed through the
holes B D to rivet the parts together, whilst the holes CE are for the passage of the
pivot, upon which the peg works when in its place in the shuttle. A completed peg
constructed in accordance with our invention is shewn in Fig 3, the spring F of the
tongue having been fitted and brazed in position.
We will now proceed to describe a modification of our invention applicable for
holding bobbins in lieu of weft in cop form. Such pegs or tongues for this purpose
are usually forged by a well known method in two halves from wrought iron. Then
the head parts are welded together, and the body part split open, thus making a very
soft springy peg, which is liable to split the ends off the bobbins, and oft-times
splits the bobbins, and so makes a very great waste of weft.
Our object is to remedy this defect by constructing bobbin pegs after the following
manner:-
We block or press an elongated trough shaped sheet metal body having a raised
head part. This will be readily understood by reference to Fig. 4 of the accompanying
drawings.
We now take a piece of drawn wire, and bend it to the shape shewn in Fig. 5,
which is similar to that shewn and described in Fig. 2. To this piece of drawn wire
bent as shewn are now fixed a tempered steel spring and a knob end. The appearance
of the bobbin peg when completed is shewn in Fig. 6.
G is the trough or channel body having rivetted to it at G¹ the bent portion H of
the wire shank shewn in Fig. 5. To the wire shank J is brazed the knob end K, and
also a suitably tempered spring L, which projects downwards into the channel of the

page_text: trough shaped body G as shewn. The darkened hole L' is for the movement of the
peg upon its pivot in the shuttle..
Bobbin pegs or pikes constructed as described give and take to the application
and displacement of the bobbins, which are readily placed in position or removed, yet
the pegs are stronger and not so liable to split the bobbins as those of the ordinary
construction.
The next part of our invention consists of an improved device for holding bobbins
in the shuttle in substitution of the usual peg or holder, and is more particularly
serviceable where long bobbins are used, which with the ordinary peg or pike are very
heavy, and bear down the peg in the shuttle, which is a great disadvantage. Besides,
such pegs as a rule, split the bobbins or wear or damage the ends of same.
improved device is intended to overcome these defects, and to provide a bobbin
holder which will be unaffected by the length or weight of the bobbins.
+
Our
In the first place we make a cap or disc of the respective shapes represented in
Figs: 7 and 8. These are formed with slots to correspond with the slots in the bobbin
head. They are also provided with holes M for fixing by screws to the bobbin head,
and are formed with a curved recess, which serves the purpose of fixing the bobbin to
our improved bobbin holder, in the manner hereinafter explained.
Our improved bobbin holder is represented in Fig. 9 with the bobbin in position.
It is inade with a short body part or shank N, shewn in dotted lines, which fits into
the bobbin when the latter is placed in position in the shuttle. On the top of our
improved holder or device O for receiving the bobbin is fixed short blade spring P.
To secure the bobbin in position on our improved holder, the bobbin is turned round,
until the spring P enters the recess P¹ of the disc or cap, shewn in Figs. 7 and 8,
when the bobbin becomes locked in place.
The holder may be fixed or movable in the shuttle, i.e. the holder may be firmly
rivetted in the shuttle, and the bobbin slipped on its short shank, or it may be
pivotted like the ordinary shuttle peg.
Figs. 10 and 11 represent our improved device or bobbin holder in another form.
In this instance, the disc Q is provided with a tubular extension Q, which is forced
inside the bobbin. This tubular extension is tapped to receive the screw end Q² of
the bobbin holder. The spring of the bobbin holder is here (Fig. 11) indented at
the end, so as to dispense with curved recess P¹ the said indented spring snecking
into one or other of the recesses P².
There are many advantages in connection with this part of our invention. The
bobbin is more firmly secured to the peg, and there is no dropping down of the nose
of the bobbins, and no giving way of the shuttle springs commonly used to a loose
working peg head, because these are dispensed with where our improved holders are
permanently fixed in the shuttle.
Our invention further relates to weft fork holders. Weft fork holders as a rule are
made or forged by hand hammers, the heads of the same being welded on the shank
of the holder. Such heads have a tendancy to come off. Besides there are all kinds of
twist in a forged fork holder, which is very much against the sweet, easy working
of the weft fork. Another method has been to form a square hole in the weft fork
holder head (in this case made of cast malleable) and then rivet to the same a round
shank with a square end, but such often come loose.
In our new and improved form of fork holder, we make, the round rod or shank to
the length required, and then recess. the same. This recess takes the form shewn in
Figs. 12 and 13 (Sheet 2).
We then make loose malleable iron or other metal heads of the shapes shewn in
Figs. 14, 15, 16 and 17. These are cast or made with pins R and formed with
grooves or otherwise in them. When grooves R¹ are made at the side of the holder
head as shewn in Figs. 15 and 16, these are made of such a depth and shape as to
correspond with the recessed portion of the shank, shewn in Fig. 12, or this recessed
portion may be readily made to fit on the pin R at the bottom of the fork holder,
illustrated in Fig. 14, the bottom of the holder head being embedded in the recess of
shank. When the recess in the shank of the fork holder takes the particular form
:

page_text: represented in Fig. 13, we form the holder head with a half round extension S having
a flat bottom with two pins R R cast to it. The shank has two holes drilled in it to
fit on the pins R R of the extension S, and we rivet the same in position instead of
having only one hole drilled in it as represented in Fig. 12.
The next part of our invention relates to weft forks of looms, and is intended to
provide a ready means of detachably fitting the prongs in the body of the fork, so
that in case one breaks, either by coming in contact with the weft fork grate, or by
being struck by the shuttle, it may be readily replaced. We are perfectly aware
that many devices have previously been invented with the same object in view, but
our invention possesses advantages over the same.
Weft forks are made according to this part of our invention as follows:-We
proceed to make loose fork prongs or legs from round flat or oval shaped wire, and
bent to the shape represented in Fig. 18.
.The solid body part of our improved weft fork is formed from sheet metal
pressed or forged to the shape illustrated in Fig. 19. It is formed with three
holes T, an arched portion U, and three cross grooves U¹ U2 and U³. It is also
struck up at right angles at the end as shewn, this being also provided with holes
recesses or grooves V V1 V2
We now take the fork prongs (Fig. 18) and place their bent ends W into the
holes T, their U bends T¹ fitting into the grooves U1 U2 and Us of the arched
portion U. The extended portion of the prongs falls into the recesses V, V₁ and V2,
these recesses together with the holes T firmly holding the prongs in position.
The U portions T¹ complete the circle or boss for the reception of the socket. The
socket may be a piece of tubing cut to length, and forced between the bends T¹
of the prongs and the arched portion U of the fork body part; or the socket may
be of the respective forms illustrated in Figs. 20 and 21. In Fig. 20 the socket..
is made with circular grooves X for the prongs to rest in. In Fig. 21, the socket is.
provided with a fixed flange X', and a removable flange X². Our improved weft.
fork with detachable prongs is illustrated as complete in Fig. 22.
We will here proceed to describe the next part of our invention, which has .
reference to that class of spindle studs, in which a strip or piece of metal is fitted.
into a groove or recess in the face of the stud, so that when worn it may be
replaced.
.
According to our invention we cut a groove clean across the face of the spindle
stud and in it bore a central hole. We now take a piece of metal of the same
length, width and thickness as the groove, and cast or furnish it with a central
pin. We fit the pin into the central hole of the stud, when the metal plate will enter
the groove and come flush with the face of the stud. The plate has two
countersunk holes formed in it at each end, either being used for the reception.
of the loom spindle. When one hole has become worn, the plate is reversed in:
position in the groove of the stud, and the other hole presented to the action of the
loom spindle. Fig. 23 is a perspective view of a loom spindle stud with a groove Y"
clean cut across its face. Fig. 24 represents the plate to fit into the groove Y and
provided with a stud Y¹ to enter the hole Y2 in the stud as shewn. It is also
furnished with counter-sunk holes Z, into one or other of which fits the loom spindle,
and when one hole has become worn the plate is reversed in position in the groove Y,
and the other. hole presented to the action of the loom spindle.
Instead of the detachable face plate being provided with a fixed stud, as shewn in
Fig. 24, it may be formed with a slot Y5, see Fig. 234, into which fits sets crew Y³ to enter
hole Y2 of the stud, (see Fig. 23), which in this instance is tapped to receive same.
By this means the face plate is rendered adjustable on the face of the stud, and the
loom spindle shifted in position as desired to suit circumstances.
:
This invention relates further to loom shuttle guards, and consists in arranging a
suitably shaped bracket, which is fixed about the centre of the sley cap in a vertical
position, and which is fitted with a sliding catch bolt, and a spiral push spring; so
that on the shuttle guard or rod being dropped in position to act as a guard, it falls

page_text: Quer a suecked end of the catch, and by it is firmly held until pushed out of position
by hand.
:
The construction of our improved bracket and spring bolt for retaining the guard
or rod in effective position will be understood by reference to Figs. 25 and 26.
The guard or rod u may be cranked at its extremities as shewn, and mounted in
brackets at each end of the slay cap or hand rail. In the centre of the sley cap, and
in a vertical position we fix the bracket b shewn enlarged in Fig. 26. This bracket
is formed with end lugs c through holes in which slides the catch bolt d acted on by
push spring e. The catch extremity is inclined at the front and formed with recess f
at the back, into which the guard or rod falls by gravity.. Fig. 25 illustrates the
guard or rod in position.
Figs. 27, 28, and 29, represents a method which we have devised for holding the
ends of shuttle guards in position. A hole has usually been hitherto bored clean
through the sley cap, and the bolt carrying the bracket passed through and secured
by a nut. Now this mutilation of the sley cap is decidedly objectionable, and this
portion of our invention is designed to get rid of that objectionable feature.
We first stamp, cut or cast a metal plate, with holes g at the corners, and a square
hole in the centre, as seen in Fig. 29.
We now pass a bolt h¹ with a flat head and a square shoulder to pass through the
square hole in the plate, as diagram 28. The plate is secured with the face h to the
sley cap by screws passed through the holes g, a counter-sunk hole being formed in
the sley cap for the reception of the bolt head. We now make an adjustable bearing
for holding the extremities of the guard or rod with a slot j, as seen in Fig. 29.
This adjustable bearing by its slot, we then slip on the projecting extremity of the
bolt, and secure thereto by a nut. By this means, the bearing may be readily
adjusted, either up or down to suit the shed of warp, either for a wide or narrow shed.
The adjustable bearing is a great advantage, because it often happens that when a
guard has been fixed to suit the shed in weaving one class of goods in the loom, it
is totally unsuited for another.
The next part of our invention relates to a novel arrangement for letting back the
warp to the extent of one, two or more teeth of the ratchet wheel of the taking-up
motion on the operating and retaining catches being raised, so as to prevent cracks,
thick or thin places in the cloth when the loom is again set in motion after the
absence or breakage of the weft.
Different methods have previously been devised to attain this object, but only with
indifferent success. In the present invention we continue the ratchet wheel shaft
of the taking up motion through the loom side, and at its other end to that on
which the present ratchet wheel is fixed, we fix another or additional ratchet wheel
to move in unison with it. We mount on a stud at the inner side of the loom an
adjustable slip catch to engage with the teeth of the second ratchet wheel and
adjustable as desired to let back one two or more teeth. Now, when the catch rod
finger is pressed by the weaver when setting on the loom after the absence or
breakage of the weft, the retaining and operating catches of the ordinary ratchet
wheel of the taking up motion are thereby raised in the usual manner. As is well
known this has the effect of letting back the warp, but to what extent has not
hitherto been satisfactorily determined; the result being thick or thin places in the
>cloth. With the application of our invention, the adjustable slip catch acting in the
teeth of the second or additional ratchet wheel only allows a recoil in the taking
up motion to the desired extent. We are perfectly aware that such slip catches have
been applied to the ordinary ratchet wheel of the take up, but owing to the cramped
.condition of the taking up mechanism, such slip catches have never been got to
satisfactorily do their work. Quite different, however, is the case in our invention,
as the slip catch acting in the teeth of the second ratchet wheel will let back the
warp to the desired extent.
The additional ratchet wheel may be fixed on the shaft and next to the present
ratchet wheel, with which it may be cast, so as to form a double ratchet wheel, but
we prefer the foregoing method because it leaves plenty of room.

page_text: In Figs. 30 and 31 (Sheet 3) of the annexed drawings will be seen our improved
arrangement for letting back the warp to the extent of one, two or more teeth of the
ratchet wheel of the taking up motion on the operating and taking-up catches being
raised.
Referring to Fig. 30, k is the present ratchet wheel, its shaft, which is extended
and passed through the loom side m, and on the said shaft is then fixed another or
additional ratchet wheel on the inside of the loom frame. Engaging in the teeth
of this additional ratchet wheel is an adjustable slip catch ¹, which lets back the
warp to the extent of one, two or more teeth. This is brought about by its catch
extremity sliding in the boss 13, and regulated by the set screw to the number of
teeth it is desired to let back.
The next part of our invention consists of an improved arrangement of fork holder
slide, which is intended to be worked in conjunction with the preceding arrangement
for letting back the warp, so as to produce an automatic recoil in the taking up
motion, on the stoppage of the loom through the absence or breakage of the weft.
This we accomplish by a novel connection or combination of catch rod finger with the
improved arrangement of weft fork slide.
This arrangement will be readily understood by reference to Fig. 32 of the
accompanying drawings.
m is the fork holder bracket constructed in the form shewn, and fixed to the breast
beam by slotted projection m². The fork holder m³ slides through lugs m of the
bracket m¹ and carries slide piece m', which is secured to the weft fork holder m³ by
set screw mª.
The catch rod finger n of the loom we pass through a slot between the bracket m¹
and the slide piece m³. When the weft fork fails to rise on the absence or breakage
of the weft, the fork hammer draws the fork holder m³ back in the usual manner.
Consequent upon this motion, the slide piece m' is caused by the fork holder m³ to
bear or press against catch rod finger n and thereby turn the catch rod n¹ thus raising
and operating the retaining catches of the taking up motion in the well known
manner. At the same time the extended portion n² of the slide piece m' comes against
the swing lever of the loom, and by that means knocks the spring handle from its
detent, instantly stopping the loom. The slide piece m is held in this position by
the spring bolt ³, which leaves the indent nt and enters indent n' of the extended
portion of the slide piece m³. When the loom is again set in motion the extended
portion of the slide piece n² is pushed forward by the swing lever through the medium
of the spring handle, and the catch rod finger again relieved when the operating and
retaining catches are thus re-engaged with the teeth of the ratchet wheel of the taking
up motion.
Simultaneously with the disengagement of the operating and retaining catches with
the teeth of the ratchet wheel of the taking up motion, the additional ratchet wheel
(see Figs. 30 and 31) lets back the warp to the extent of one, two or more teeth
according to the limited movement of the adjustable slip catch l
In this way we are enabled to produce an automatic recoil in the taking up motion
according to the texture of the cloth, the said slip catch being regulated to a nicety
by the overlooker, who has the looms under his charge.
The next part of this invention relates to what is known as Smalley's shedding
motion (Patent No. 4874 of 1876) and our improvements are designed to consider-
ably increase the capacity, effectiveness and utility of this shedding motion, whereby
we are enabled to obtain a far greater number of treads to the round than is ever
obtainable or conceived of under the arrangement at present in use, besides many
other distinct and important advantages. As is well known Smalley's motion is
worked from a bevil wheel mounted on the tappet shaft, which gears into another
bevil wheel fixed to a vertical shaft, which enters a footstep at the bottom of the loom,
and is passed through the warp threads to a suitable distance above the loom, where
it is provided with a bevil wheel at its end, which gears into the teeth of a large plate
Now this method of driving
bevil wheel, which operates the shedding motion.
possesses many objectionable features. The vertical shaft going, through the warp

page_text: 'rubs the twist, and loose or broken ends sometimes get entangled round the same ;
moreover, the female operative's hair has sometimes caught in the gear wheels at the
top. The method of driving is also disadvantageous from the fact that it is very
shaky, and rocks on the loom, which is no good for the well making of cloth.
.
In the present invention, we remove the shedding notion from the top of the loom,
and place the same inside the loom and on the floor. The frame which carries the
working parts of our improved shedding motion is fixed to the binders or cross-rails of
the loom. We reverse the tappets so as to act on the top of treadles, pressing them
down and pulling down the healds. At the top of loom is placed a spring easing
motion, which lifts the healds up.
In combination with the arrangement described, we also employ a novel driving
arrangement, whereby if desired we can duplicate Smalley's motion, and con-
siderably increase its range or capacity for work.
In the accompanying drawings, Fig. 33, Sheet 5, is a detached perspective view of
our improved shedding motion, and cross-rails of a loom fitted according to our
invention.
o is the tappet shaft of the loom. On the tappet shaft we fix toothed gear
wheel o¹. This we will call the driver, for from it our improved shedding motion is
operated. We now mount in slide bearings o², which are adjustable in slots in the
cross-rails o³ of the loom, a horizontal shaft ot, which runs parallel with the tappet-
shaft o. The toothed gear wheel o¹ drives this horizontal shaft of through the
medium of gear wheel o5.
On the horizontal shaft o, we fix two bevil wheels p, which drive large plate bevil
wheels p¹ and p2 mounted on cross shafts q¹ and q². These cross shafts q¹ q2 are
mounted in bearings in a suitable frame, which for convenience has not been shewn
on the drawings. Cross shafts q¹ and q² are each provided with a series of barrels > 1
and nogs or tappets 23, which bear upon treadle levers s, and thereby depress the
healds. The treadle levers 8 are guided in grates constructed with the frame,
and are loosely mounted on shafts s¹ carried by the said frame.
The number of barrel plates r r and tappets or nogs 2 3 vary according to the
number of treads required to the round. The number of teeth in the large plate
bevil wheels p¹ or p² divided by the number of teeth in the small bevil wheels p
determine how many treads to the round the two sets of tappets shall go.
.
From the foregoing description of our invention, it will be perceived that by the
novel arrangement of the horizontal shaft placed parallel with and driven from the
tappet shaft o by gear wheels o¹ and o³, we are enabled to duplicate Smalley's motion,
i.e. we work two sets of tappets in the same framework, one set being driven by
cross shaft q' and the other by cross shaft q2. Although we have shewn and
described our invention as being applied with two sets of tappets and treadles
operated from the horizontal shaft, it is perfectly obvious that only one set may be
employed, where only a small range of work is required.
We can still further increase the capacity of our shedding motion by providing the
large plate bevil gear wheels p¹ and p² with 120 teeth instead of with only 60 teeth
as is usual in Smalley's motion. By this means, we can work with eight treads
to the round on both sides, if need be.
To indicate our meaning clearly, we will give instances of practical application :-
Assuming that the wheel p have 40 teeth and it geared into the wheel pl
with 120 teeth this would go 3 to the round, or six picks in the cloth.
A 30 wheel would go 4 to the round;
a 20 wheel would go 6 to the round;
and a 15 wheel would go 8 to the round;
which would be equal to 16 picks in the cloth.
By placing a gear wheel o¹ with 15 teeth on the tappet shaft, and a wheel 05 with
30 teeth on the horizontal shaft, we can make our improved shedding motion go 16
to the round, equal to 32 picks in the cloth. Not only that but by duplicating the
arrangement as described we are enabled to use twice the number of treadles as was
possible under Smalley's motion. One set of tappets may be arranged to work or play.

page_text: on the treadles on one side of the loom; giving a certain number of picks to the
round say 3, and the second set of tappets may work or play on the other treadles
giving 4 to the round; that would give two distinct cloths, say a three shaft twill and
a two and two stitch in the cloth. We wish our meaning to be made clear in. this
respect that when the treadles or levers are acted upon by the tappets at one.. side of
the loom with the object of increasing the number of treads to the round; the said:
levers are not played upon by the tappets at the opposite side, but are entirely
separate and distinct therefrom and vice versa, that is to say, that the levers and
tappets on either side are individual and independent of the others, except in cases
where a dwell is required. Thus the tappet ³ acts upon an entirely independent lever
similar to z whose corresponding or twin lever s serves no other purpose than to
depress the stave from the opposite side, but is not acted upon by any other tappet.
As arranged in the manner described our improved shedding. motion: is easier to
adjust or change to different makes or patterns of cloth, and the tappets or nogs in
this case cost less than the tappets of the Yorkshire or cross-rod loom.
There is also another special feature of our invention. The tappet 2 on one side
of the loom may play on lugs x of the levers s at that side of the loom, and just as
the said tappet 2 is leaving the said lever, the tappet r³ at the opposite side of the
loom may be caused to play on a lug cast to twin lever z at that side, and cause any
particular stave to dwell any definite time.
An intermediate gear wheel may be introduced between the wheels o¹ and of to
slow down or increase the speed of horizontal shaft ot, so that if we wanted, we can
run a four tread 8 to the round, or a six tread 12 to the round.
