CERTAIN IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1854

page_text: LETTERS PATENT to William Bramwell Hayes, of Manchester, in the
County of Lancaster, Manufacturer, for the Invention of "CERTAIN
IMPROVEMENTS IN LOOMS FOR WEAVING."
Sealed the 9th March 1855, and dated the 14th September 1854.
PROVISIONAL SPECIFICATION left by the said William Bramwell Hayes
at the Office of the Commissioners of Patents, with his Petition, on the
14th September 1854.
I, WILLIAM BRAMWELL HAYES, of Manchester, in the County of Lancaster,
Manufacturer.do hereby declare the nature of the said Invention for "CERTAIN
IMPROVEMENTS IN LOOMS FOR WEAVING". to be as follows:-
My said Invention has reference chiefly to looms constructed with moveable
shuttle boxes, and intended for the production of fabrics wherein the weft
interwoven is varied from time to time by changing the shuttles. It may,
however, be partially applied with looms to fixed shuttle boxes.
To effect the changes of the shuttles I use any required number of shifting
boxes, similar to what are commonly called "drop boxes;" but I arrange and
connect them so as to form an endless chain, which revolves upon rollers
mounted on the sley, by which revolution of the chain each box is brought
successively into its working position.
I apply mechanism whereby motion is imparted to the endless chain of boxes

page_text: from the main shafts of the loom at intervals, regulated so as to change the
shuttles according to the pattern to be produced.
In order that the weft which is out of use may not become entangled by the
revolution of the chain of boxes, I apply apparatus for severing the weft last
used at each shifting of the boxes, and for laying hold of and retaining the end
of it when the shuttle which carries it is restored to its working position, so as
to ensure the insertion of the first pick. This improvement is applicable to
any kind of revolving shuttle box.
'The endless chain of boxes interfering with the application of the ordinary
stop rod, I substitute a new arrangement of mechanism for stopping the loom
when the shuttlo fails to reach the box in due time; and 1 connect this
mechanism with a break applied to the fly wheel, in such manner as to make
it effect the application of such break for that purpose when required. Iapply
a break of a new construction to the fly wheel, the skid or part which comes
into immediate contact with the wheel forming part of a hoop concentric with
the wheel, but of larger radius, and the spring or elasticity of which, tending
to restore it to its proper curvature when liberated, is sufficient to prevent it
from adhering or becoming set fast to the wheel.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Bramwell Hayes in the Great Seal Patent Office on
the 14th March 1855.

NOW KNOW YE, that I, the said William Bramwell Hayes, do hereby
declare the nature of my said Invention, and the manner in which the same
is to be performed, to be particularly described and ascertained in and by the
following statement, that is to say :-
4
My Invention has reference to machines of the class commonly known as
power looms." It consists,-
Firstly, in the arrangement of and in the method of working a series of
moveable shuttle boxes, whereby Iamenabled to employ a number of shuttles
adapted to succeed each other in a prescribed order, and entering upon and
retiring from their operations at stated intervals without interruption to the
evolutions of the loom, so that by charging such shuttles with weft of different
kinds or colors a patteru may be produced in the fabric.
Secondly, in a method of suddenly arresting the advance of the sley and
suspending the movements of the loom in the event of the shuttle failing to
complete its transit through the shed in due time, and in a combination of
mechanical parts for that purpose,constituting a novel descriptionof "stop rod,"
or "protector," which may be employed as a substitute for the more cum brous
appendage usually designated by that title.
Thirdly, in the peculiar form, configuration, and construction of a "break"
to be applied to the fly wheel, for the purpose of mitigating the shock or con-
cussion ensuing between the fixed and moving parts of the machine upon the
sudden arrestation of its movements by the action of the stop rod, or any
equivalent agent.
I shall descrine these improvements with the manner of carrying them into
effect separately and distinctly in the foregoing order; and to render the mutual
relations and connexions to and with each other of the several parts of the
mechanism employed more readily comprehended, I have annexed to these
Presents a Sheet of Drawings, containing views of so much of such mechanism
or apparatus as will suffice to render my description easily intelligible.
Of these, Figure 1 represents a back view of part of the skeleton or frame
of a loom, the two principal shafts, the sley, and driving pulleys, with my
improvements attached thereto. In this, as well as in the other views, such of
the other ordinary parts of the loom as have no immediate connexion with the

page_text: subject of this explanation have been omitted for the sake of perspicuity.
Fig. 2 is a view from the interior of the loom towards the side on which the
moveable shuttle boxes are placed, shewn as if projected on a vertical plane,
intersecting the loom at a little distance from and parallel to that side, and
exhibiting the relative positions, connexions, and arrangements of the parts
employed to produce the changes of the shuttles, and to regulate the times of
such changes. Fig. 3 is an elevation view, taken externally, of the setting-on
side of the loom, shewing the arrangement, form, and respective positions of the
novel or improved "stop rod" and "break." The other Figures are detached
views of various parts, to which references will be made in the course of the
following statement, and which will be more conveniently particularized as
such occasions occur. Throughout all the Figures the numerical characters
by which the several parts are identified when they occur more than once are
to be understood as indicating the same parts or things.
The first in order of my improvements is that for effecting the changes of the
shuttles from time to time, and which I accomplish as follows:--I connect
together a series of shuttle boxes, corresponding in number with the shuttles
to be employed, by means of hinge joints, so as to form an endless chain. The
chain of boxes thus constructed is suspended upon rollers, which revolve in
bearings carried by the sley. It is moreover so arranged, that by the turning
of one of the rollers each of the boxes composing the chain is successively
brought into its working position. On the axis of the turning roller is fixed a
ratchet wheel, the teeth of which is acted upon by a click or catch at intervals,
determined as herain-after mentioned, so as to cause the ratchet wheel and
roller partially to revolve at each stroke or pull of the catch, being moved on
each of such occasions to such an extent as to advance the chain of boxes
through a space equal to that occupied by one shuttle box. By each advance
of the chain the box previously in use is removed from its sphere of action, and
replaced by that which forms the next link in the chain. The click or catch
which moves the ratchet wheel receives its impulses from a cam or wiper on
the tappet shaft, or from some equivalent mover, through the medium of a
lever, which is subjected to the action of the cam at those periods only when
the order of the proposed pattern requires the shuttle to be changed. The
relative duration of the intervals between the periods at which the shuttles are
changed is regulated by the action of a pattern wheel or chain, furnished with
prominences and depressions, or risers and sinkers, corresponding as to their
aggregate number with the number of double picks contained in the round of
the pattern, and in their order and numerical.proportions with the relative
lengths of the intervals between the changes of the shuttles as measured by the

page_text: number of picks. The risers and sinkers on the pattern wheel or chain operate
to elevate or depress the intermediate lever or link which intervenes between
and establishes or interrupts the connexion of the cam on the tappit shaft with
the click or catch before mentioned. The pattern wheel or chain has a step
by step movement imparted to it by a connexion with any of the moving parts
of the loom convenient for the purpose, each step of its movement bringing
into operation a fresh riser or sinker, as the case may be; the ultimate effect
being to produce the required pattern by throwing the catch which acts upon
the ratchet wheel into gear with the wiper on the tappet shaft whenever a
change of shuttles is required. In all attempts to construct revolving systems of
shuttle boxes, great difficulty has been experienced in disposing of the portion
of weft which on the change of shuttles is left extended between the selvage
of the fabric and the shuttle last in use. No effective method has been devised
forseveringtheinterwoven yarn from the cops or bobbins in the retired shuttles,
and if not so severed it is liable to get fouled round the spindle or axis of the
boxes, or entangled with some of the adjacent parts of the sley. Even supposing
the severance to be effected, some contrivance is still needed to retain the end of
weft protruding from the eye of each shuttle when the latter comes to be
again projected through the shed. In default of such contrivance the shuttle
will be apt to pass through the shed without inserting the pick or shoot of
weft; part of my present improvement therefore is designed to supply these
deficiencies. For the purpose of severing the interwoven weft from that which
remains in the retiring shuttle, I use a pair of shears or scissors, affixed to the
breast beain or frout framing of the loom, in such manner that their blades
project across the sley when the latter is in its most advanced position, and
these shears, being actuated by the same mechanism which alters the position
of the moveable boxes from time to time, close upon and divide the weft
between the nearer selvage of the fabric and the shuttle at the moment of the
removal of the latter. The end of weft depending from the shuttle is first
withdrawn from the shuttle race by a hook, and subsequently following the
motion of the chain of boxes, drops into a guiding groove or trough, which
conducts it clear of all impediments, and prevents its fouling. A spring is so
applied as to press closely against the inner end of the boxes at the rising side
of the chain, and as each box is in turn brought into its working position, the
pendent end of the weft is caught between this spring and the end of the
shuttle box,and thereby held fast, so as to insure the insertion of the first pick
on the shuttle re-entering the shed. The foregoing is a general outline of the
arrangements by which I accomplish this part of my improvements,and I shall
more fully demonstrate these arrangements by describing in detail a combina-

page_text: tion of mechanical parts adapted for carrying the same into effect, as repre-
sented in the Figures or Diagrains on the annexed Sheet of Drawings.
Legf
In these Figures, 1, 1, 1, &c. are parts of the ordinary framing of the loom;
2 is the crank shaft; and 3, the tappet shaft; 4 is the sley; 5, 5, the sley
swords; and 6, the swing or rocking rail. The latter is prolonged so as to
extend beyond the framing at one side by the piece 7, which forms a support
for the parts carrying the inoveable boxes. 8, 8, are uprights, attached to the
continuation 7 of the swing rail, and rising to about the same height as the
ordinary sley swords. These uprights are firmly braced to the sley by a cross
piece 9, and by a clamp plate, not seen in the Drawing. Figure 6 is an end
view of the system of boxes, taken close to the inner upright. In this view, 10
is a square roller or barrel, with leaves or tongues projecting radially from its
corners; its axis or spindle turns in sockets in the uprights 8, 8. This roller
or barrel carries the chain of moveable boxes. The boxes composing this chain
are marked 11 in all the Figures where they appear. In the present example
they are twenty in number, but that number might be either greater or less,
according to circumstances. 12, 12, &c., are the backboards of the boxes, and
the chain is formed by hinging the adjacent edges of these backboards
together; 13, 13, &c., are springs,for the purpose of binding the shuttles, and
preventing their recoil or escape from the boxes; 14 (Figure 6) is another
roller, which acts as a fulcrum, round which the chain makes its lower turn in
revolving. The general form of the chain or system of boxes will be well and
easily understood by an inspection of the end view, Figure 6, and of Figure 5,
which latter shews a side or elevation view of the boxes from behind the sley,
and also some other parts, which are partly concealed by the framing in Figure1.
Figure 4 is a plan view of the moveable boxes and their mountings, together
with some adjacent parts. 15 (Figures 2, 4, and 5) is a click or catch, which
takes into the ratche: wheel 16, fixed on the spindle of the roller 10. This
ratchet wheel, in the present instance having four teeth, is turned one-fourth of a
revolution by each reach of the catch, the roller 10 turning with it to thesame
extent. The small leaves projecting from the corners of the roller 10 insert
themselves between the adjacent edges of the backboards 12, 12, &c., so that
the boxes necessarily accompany the roller in its movements. In order to
steady the roller 10 and the chain of boxes after each change of position, there
is a spring 17, bolted to one of the uprights 8, and bearing against one side of
a square boss 18, attached to one side of the ratchet whee! 16. The catch or
click 15 is jointed at its lower extremity to the horizontal arm 19 of a bell
crank lever, pivoted on a stud 20 (see Figure 2). The vertical arın 21 of this
lever is presented towards an arm or finger 22, which is pivoted on a stud in

page_text: the oscillating lever 23, the latter swinging from another stud 24 in the loom
side. 25 is a bowl or friction roller, with which the lower extremity of the
lever 23 is armed, and which bowl rests in contact with the periphery of the
cam or wiper 26, carried by the tappet shaft 5. The cam 26 vibrates the lever
23 at each revolution of the tappet shaft, impelling the finger 22 towards the
upright arm 21 of the bell crank lever, connected with the catch 15; the
point of the finger 22 would consequently, if not elevated, act upon the catch
15, and cause it to move the ratchet wheel 16 at every revolution of the
shaft 3. To prevent this, the finger 22 is, by means hereafter to be pointed
out, raised clear of the lever arm 21 at all times, except when a change of
shuttles is required. The cam 26 is so adjusted on the shaft 3, that its action
on the oscillating lever 23 always takes place upon the return of the shuttle,
and after the crank has passed its top centre, and consequently, after the
shuttle is boxed, and as the next pick will not be made until the crank
approaches the lowest point of its orbit, there is ample time for the shifting of
the boxes to be effected before the next shuttle is required to enter the race.
By inspecting the Drawings and tracing the connexions of the parts, it will be
easily seen how the cam 26, acting through the oscillating lever 23, the finger
22, the bell crank lever on the stud 20, and the catch 15, operates to effect
the rotation of the ratchet wheel 16, and to turn the roller 10, so as to impart
a revolving movement to the chain of boxes. It remains to be seen how the
fiuger 22 is elevated in order to interrupt the connection between the oscil-
lating lever 23 and the bell crank lever, and to prevent the action of the cam
26 from extending to the ratchet wheel 16, and how it is again depressed for
the purpose of restoring that connection whenever a change of shuttles is
required to be made. An endless chain, composed of a series of flat links or
plates connected by rings, (27, 27, &c., Figure 7,) revolves upon two small
pulleys or wheels 28 and 29. The pulleys turn upon studs mounted in fixings
attached to the loom top. The chain must contain half as many links as there
are picks in the round of the pattern, and in order to admit of its being
lengthened or shortened accordingly, the stud on which the pulley 29 runs,
and the arm or bracket by which it is carried, admit of their positions being
varied to a considerable extent, as will be seen by the peculiar form of the stud
arin or bracket. The links of the endless chain have pins screwed into them,
such pins generally having large and prominent heads, as at 30,30, &c. &c., but
in some of the pins these heads are deficient, as at 31, 31, &c. &c. The links
with the iurge headed pius act as risers, and those with the headless pins as
sinkers, for the purpose of producing and regulating thechanges in the pattern.
The ends of the pins project below the chain to some extent, and take intoa

page_text: series of holes prepared to receive them in the periphery of the pulley 28, so
that the pulley and chain are constantly in gear, and must necessarily move in
unison.
33.
Figure 7 represents a section through the middle of the pulley 28 with a
portion of the chain embracing it, being drawn to a scale of about half the
natural size. Behind the wheel or pulley 28 and attached to is a ratchet
wheel 32(Figure 2), which is engaged with aclick or catch carried by the lever
The latter is attached by a rod 34 with another lever 35 pivoted on a
stud in the lower part of the loom. The tail of this last lever projects under
and is acted upon by the cam 26, being depressed by it once in each revolution
of the tappet shaft. By this means, at every revolution of the tappet shaft, the
ratchet wheel 32 and pulley 25 are moved one tooth, the chain being also
advanced one link; for it will be seen, by inspection of Figure 7. that each tooth
of the ratchet wheel 32, shewn in that Figure by dotted lines, corresponds
with the space on the circumference of the pulley taken up by one link of
the chain.
It may also be remarked, that the action of the cam 26 upon the lever 35
immediately precedes its action on the pendent lever 23, so that the result of
the latter action will be governed by the form of link previously brought into
position by the former. Immediately over the pulley 28 is a lever 36, having
its fulcrum or pivot at 37, and furnished with a swell 38 projecting down-
wards. This swell rests upon the link of the chain, which for the time being
occupies the top of the wheel, and is elevated or depressed according as
that link is furnished with a large headed pin or with one of the contrary
description. The lever 36 is connected by a rod 39 with the finger 22,
before described, and when the lever 36 is raised by any of the risers carried
by the pattern chain, the finger 22 is raised also, and its point passes over
the upright arm 21 of the bell crank lever, so that the vibration of the oscil-
lating lever 23 communicates no impulse to the click or catch which actuates
the chain of boxes; on the contrary, when the link of the pattern chain
passing over the top of the wheel or pulley 28 is furnished with a headless
screw, it acts as a sinker, and permits the lever 36, and consequently the
finger 22, to remain depressed, and the point of the finger 22, in this case
coinciding in position with the top of the lever arm 21, acts upon the latter,
and causes an advance of the chain of boxes by the connection before pointed
out. The sinkers of the pattern chain having been previously arranged at
such intervals in the chain as to correspond with those required by the order
of the pattern between the changes of the shuttles, it is evident that the
ultimate result of the whole action will be to change the shuttles in the pro-

page_text: posed order and times. In the plan view, Figure 4, and sectional view, Figure",
40 indicates the shears or scissors employed to divide the weft. They are
mounted on a bracket attached to the breast beam, and project inwards far
enough to cross the shuttle race when the sley is at the beat up. Their lower
bladeisstationary, and sunk below the level of the shuttle race within a groove
prepared for its reception, so that the weft extending from the salvage to the
shuttle in the adjacent box overlies or crosses it. Their upper blade is con-
nected by a link 41 with the lever 42, one end of which is pivoted on a stud at
the front of the loom. The other end is attached by a joint pin to the hori-
zontal arm of the bell crank lever, which actuates the catch 15; consequently,
whenever the bell crank lever moves the catch, it also closes the blades of the
shears, and severs the web. A hollow conducting trough or guiding groove
43 passes upwards over the spindle of the roller 10; a hook 44 (see Figure 4)
aleo projects across the sley, occupying a groove sunk for it close to the end of
the shuttle boxes. This hook forms one arm of a small lever, the fulcrum of
which is on a pin in the framing; the arm on the opposite side of the fulcrum
being connected to the link 41, so that when'the blades of the shearsare closed
the hook is raised, and, catching the straggling end of weft as the sley recedes,
draws it clear of the shuttle race. The subsequent rising of the box combined
with the action of the hook deposits it in the guiding groove 43, which con-
ducts it clear of obstructions until it follows the shuttle in the descent of the
latter on the other side of the roller 10. When the shuttle in its revolu-
tion again approaches its working position, its end is pressed by the spring
45, and the end of the weft depending from it is detained between the spring
and the end of the box with sufficient tenacity to insure the due insertion of
the weft at the first throw of the shuttle. The last particulars complete the
description of that part of my improvements which relates to the arrangement
and working of moveable shuttle boxes.
I shall now proceed to the second branch of the Invention, namely, the
method of arresting the movements of the loom in the event of the shuttle
being trapped, by means of a novel kind of " stop rod," intended to supersede
that in ordinary use. The common stop rod, by the pressure which it exerts
upon the shuttle in its exit from the box, and the resistance which it opposes to
its entrance, renders necessary a greater amount of force in the pick than is
required for the mere trajection of the shuttle. The violence of the impulse
causes it to be accompanied by a very aggravated strain upon the machine,
causing rapid wear and tear of the wheels, as well as of the pickers, and other
subordinate parts. To releive the loom from a portion of this strain is the
object sought by the present improvement, which is also peculiarly adapted for

page_text: use in connection with the system of moveable boxes, before described. Ine
novel stop rod which I employ extends across the loom immediately in front of
the sley, being mounted in bearings upon the upper rails of the side framing.
The rod is furnished with two fingers, directed horizontally towards the sley,and
falling opposite to corresponding projections firmly attached to the sley or sley
swords, which projectious the fingers meet and become locked with when the
stop rod is at rest, and thus obstruct the further advance of the sley. In order
that the regular operations of theloommay proceed without interruption, these
fingers are raised at each advance of the sley, by the oscillation of the stop
rodproducedas follows:-The rod carries besides the fingers before mentioned
two uprightarms, which rise in front of the sley, each of them being opposite
to the middle part of one of the shuttle boxes. The higher extremities of
these arms are furnished with fingers or feelers, presented towards the shuttle
boxes, and when the stop rod is at rest projecting into them through holes or
ntervals left in the shuttle guards. If a shuttle be present in either of the
boxes, it obstructs the entrance of the feeler, aud, repelling the latter as the.
sley advances, imparts to the upright arm a radial movement round the axis of
the stop rod, which raises the horizontal fingers clear of the projections on the.
sley, so as to permit the latter to continue its beat up. But if both the shuttle
boxes be empty, and no impediment offered to the entrance of the feelers, the
stop rod remains at rest, and the horizontal fingers arrest the further advance.
of the sley. In Figure 3 the arrangement of the above described apparatus is
exhibited in side view. 46 is the stop rod and its bearing block, which latter
may be either firmly fixed or made to slide upon the top rail of the loom side,
like the common sliding frog. 47 is one of the fingers directed towards the
notched projection 48 upon the sley. 49 is one of the upright arms, and 50
the feeler, projecting from it into the shuttle box when the sley beats up. The
blocks or hearing pieces in which the stop rod is carried may of course be
made to apply a break, as well as to liberate the spring handle, in the same
manner as the sliding frog. In the present case the bearing block is shewn
as applying my improved break, by striking a spur projecting from the upper
end of the reversing lever 51, which latter reacts upon the break through the
rod or link 52.
The construction, configuration, and application of the "break" last men-
tioned constitute the third of my improvements. I make it of wrought iron or
spring steel, in the form of a strap or segment of a circular hoop, the curvature
of which is of a little larger radius than that of the periphery of the fly wheel
which it embraces. The break is shewn in side view at 53 (Figure 3), circum-
ferenting the fly wheel 54. One end is attached firmly to a bracket, stud, or

page_text: projection from the framing, as at 55. The other extremity 56 is jointed to
the rod or link 52, by which the break is applied, the force of pressure being
derived through the frog or otherwise; the method of application according
to the arrangement shewn in the Drawing has already been adverted to. The
advantageous properties of this break are, that the strap or hoop of which it
consists embraces nearly the whole rim of the fly wheel; that the tendency of
the friction or adhesion between the break and wheel is to tighten the hold of
the break, and that when released, the elasticity of the break, tending to
restore its original form, at once detaches it from the wheel, so that there
is no liability to stick, as is the case with some breaks now in use.
The preceding statement describes and ascertains the nature of my Inven-
tion, and the manner of carrying the same into effect; but, as in the course of
such statement mention of some parts or things not appertaining to my
Invention may have been collaterally introduced for the purpose of rendering
the explanation more complete, hereby further declare that I do not
claim as of my Invention the application or use of moveable shuttle boxes
generally for the purpose of changing the shuttles; neither do I claim the
method of bringing the break into contact with the fly wheel by the reversing
lever and rod connecting the same with the stop rod, nor any other special
mode of effecting the contact of such break with the fly wheel; but what I
do claim as novel and of my Invention in connection with the improvements
herein described are,-
Firstly, the arrangement of a series of moveable shuttle boxes in the form
of an endless chain, by the rotation of which each of the boxes composing it is
in its due course and order brought into and withdrawn from its working
position.
Secondly, the method of imparting motion to the chain of boxes by the
connection established between the roller which carries such chain and the
tappet shaft or other equivalent mover through the medium of the ratchet
wheel, catch, bell crank lever, oscillating lever, and cam, as herein-before
particularly set forth and described.
Thirdly, the method of interrupting and restoring the connection between
the tappet shaft and chain roller, before mentioned, by means of the moveable
finger carried by the oscillating lever, and the method of governing the
position of such finger so as thereby to break or restore such connection a
the desired intervals by means of the moving pattern chain or wheel, a
herein.before explained.
Fourthly, the employment of scissors or shears, actuated by the mechanism

page_text: which conveys motion to the moveable boxes, for the purposes of dividing
the interwoven weft from the residue therecf left on the cop or bobbin.
Fifthly, the method of providing an unobstructed path for the ends of weft
depending from the eyes of the retired shuttles by the guiding groove at
the end of the chain of boxes.
Sixthly, the method of apprehending and detaining such pendant ends of
weft,so as to secure the insertion of the first pick when the shuttles are again
projected into the shed, by means of the spring pressing against the ends of the
shuttle boxes, as before described and explained.
Seventhly, the special combination and arrangement of mechanical parts for
the purpose of carrying into effect and accomplishing the aforesaid methods or
objects as herein described and illustrated by the accompanying Drawings.
Eighthly, the arrangement and combination of mechanical parts constituting
the novel "stop rod," herein-before mentioned and described, and the appli.
cation of the same.
Ninthly, the peculiar form and construction of the break herein described,
consisting of a strap or segment of a hoop of iron or other metal almost
encumferenting the fly wheel.
In witness whereof, I, the said William Bramwell Hayes, have hereunto
set my hand and seal, this Thirteenth day of March. in the year of
our Lord One thousand eight hundred and fifty-five.
