page_text: COMPLETE SPECIFICATION.
I WILLIAM ROBERT LAKE of the firm of Haseltine, Lake, & Co, Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declaro the nature
of my invention for "IMPROVEMENTS IN THE MANUFACTURE OF LOOM HARNESS
AND APPARATUS THEREFOR " and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement :-
This invention relates to loom harness and machinery for manufacturing the
same and is an improvement upon the machine described in the specification of
former Letters Patent dated the 25th day of February A.D. 1874 N° 719, and it
comprises a harness formed by knitting the heddle twines to the rig-band by
successively drawing three loops within three loops, each assemblage of loops so
drawn within the preceding assemblage consisting of a binding twine, which
is wound loosely around the said rig-band, and of two heddle twines which respec-
tively connect the alternate heddle oyes of successive pairs of eyes, cach of which
is folded or looped at the said rig-band.
The invention further comprises certain combinations and arrangements of parts
and details of construction in a machine for making the said harness, all as herein-
after described.

In Figures 26 to 31 the loops are considerably exaggerated in size.
In the drawings AA are the side frames of the head or main body of the
machine, B, B the end frames and C, C and C³, the girts by which the side
fraines A, A are connected together to form a rectangular structure upon which the
main operating parts are mounted.
D is the end frame of the rearward extension of the machine and is connected
to the rectangular structure, constituting the head of the machine by the tie
rods D¹, D as shown.
E is the driving shaft mounted in suitable bearings and having firmly secured to
one end thereof the crank E¹ and to its other end the spur gear wheel E³ which
engages with and imparts motion to a train of gearing E³ E, E Eº upon the side
of the head of the machine opposite the crank end of the driving shaft as shown
in Figure 1, through which gearing rotary motion is imparted to the shafts F, F'¹
and F, and through them and suitable bevel gear wheels F³ and F, spur gear
wheels E7 E and E³, and bevel gear wheels F F and H¹ H', motion is imparted
respectively to the shafts G, G, G₁ and G² and screw H.
The driving shaft E has mounted loosely thereon the cone pulley E° which by
means of a suitable clutch and shipping mechanism may be connected to said shaft
so as to compel said shaft to revolve therewith, motion being imparted to said cone

page_text: pulley by means of a suitable belt leading therefrom to an overhead shaft or other
prime mover, not shown.
I use in this machine two stationary needles I, I, arranged one above the other
and each provided in its upper side with a longitudinal groove a, along each of
which two twines from which the heddles and loops of the harness are to be formed
are led to the two eyes in the front end of each needle in substantially the same
manner as described in the specification before referred to.
J is a vertical slotted shaft mounted in suitable bearings and provided with the
two pairs of horizontally projecting ears b, around which the twines are wound by
the twisters c, c¹ mounted in the inner ends of the shafts K and K' respectively, Bid
shaft J having secured thereon the pinion & with which the rack-teeth on the inner
end of the bar d' engage and impart thereto an intermittent rocking motion about
its axis to the extent of one quarter of a revolution, so that the heddle eyo
formers b, b, alternately point towards the needles I, I and towards the twister
shafts K and K', said bar d' having an intermittent reciprocation imparted thereto
for this purpose by the cam d² on the shaft F acting through the lever to move
it in one direction, and the spring d* to move it in the opposite direction, and the
twister shafts K and K having an intermittent reciprocating rotary motion
imparted thereto by the cam L on the front end of the shaft F' acting through the
medium of the reciprocating rack L' the pinion e, gear e¹ and pinions e³, e all
constructed and arranged to operate substantially as described in the said former
specification.
Two pairs of push fingers feach provided with a shoulder f¹ are set in the inner
end of the bar f to which a reciprocating end wise inovement is imparted by the
came f³ on the shaft F acting through the lever f' and link f³, said fingers being
thereby moved end wise through the slot in the shaft J, serving to transfer tho
heddle eyes from the formers b to the needles I, I, the push fingers f being so
arranged relatively to the needles II and so operated that as they are moved
toward the needles their shoulders f¹ abut against the twine of the heddle eyes as
it rests upon the formers b and carry the eyes onto the ends of the needles, one of
said push fingers passing above and another beneath each needle I, I.
The motion of the push fingers continues till the heddle eyes are moved along
the needles to a point in the rear of the heddle eye retainer g, where said forward
motion ceases and they remain stationary till the fork retainer g has descended in
front of said eyes. The said eyes are then moved backward till they are withdrawn
from the slot of the shaft J, the said shaft being then turned a quarter of a revolution
with the eye formers b toward the twisters, when two more eyes are formed thereon
preparatory to being in like manner transferred to the needles I, I
The pushing of the heddle eyes back upon the needles I, I causes the twines,
from which said eyes and the loops connecting them to the rig-bands, are formed,
to be drawn through the several eyes in the points of the needles and along the
outer edges of the needles to said heddle-eyes which have been pushed to the rear
of the contracted portions I¹ of said needles as shewn in Figure 22.
A pair of pointed fingers h, h are hinged by independent pivots h', h¹ to the
upright bar, arranged to be intermittently reciprocated vertically by the cam h³
upon the shaft F acting through the medium of the truck and the bracket or
arm h³ said bar being mounted in suitable guiding bearings as shewn.
The lower portions of the inuer edges of the fingers h, h are curved or cam
shaped as shewn, and are acted upon by the bevelled sides of the inner end of the
lover M for the purpose of moving the pointed upper ends of the said fingers h, h
outward or away from the needles I, I, the said lever M being vibrated for this
purpose by the cam i on the shaft F acting upon the truck i mounted upon a pin
set in the side of said lever as shewn in Figures 1 and 4.
These fingers h, h, when in their lowest positions have their upper ends below
the lower needle, and at such a distance apart that when they are moved upward
they pass between the needles and the twine that is drawn from the eyes in the

page_text: end of the needle along the outside of the needles to the heddle-eyes previously
formed, said fingers being pressed hard against the stop pin 4º by the spring
acting upon the short arms a secured upon the back ends of the pivots h¹, h, as
shewn in Figures 5 and 6.
When the bar h and the fingers h, h have completed their upward movement, 5
an upward movement of the inner end of the lever M forces said fingers to move
about their pivotal axes, drawing out therewith a loop of twine upon each side of
each of the needles I, I, as shewn in Figure 5.
N, N are two levers arranged upon opposite sides of the central vertical plane
occupied by the needles I, I, each having secured to its upper end two hooks j. j and 1
being pivotted at its lower end to the movable end of a lever N¹ pivotted to the
stand N2 as shewn in Figure 3.
•
Each of the levers N and hooks jj has an intermittent endwise inoverment
imparted thereto by a cam N³ on the shaft G acting through a lover N*, rod N³, and
the lever N' and a vibrating motion about its pivotal connection to the lever N¹ is ]
imparted to each of the levers N by the crank No carried by the shaft G and acting
through the connecting-rod N7, as shewn in Figure 3 and substantially as described,
in the said former specification.
The endwise and vibratory motions of the levers N are so adjusted and timed
that the hooks j j in their upward movement pass within the loops of twines just
previously drawn out by the fingers h h and, as the levers N vibrate, the said
hooks engage with the two loops upon each side of the heddle needles, and taking
them from the fingers h h carry them beneath, and a short distance beyond the
rig-bands O, when said loops are lifted from said hooks j, j by the upward
movements of the hooks P mounted upon the short shafts P¹ having their bearings
in the adjustable strands P and each carrying a lever P³ having mounted in its
movable end a truck k upon which the cam P' on the sleeve shaft Q acts to vibrato
the hook P.
Each of the rig-bands is secured by one end to the adjustable arm k¹ mounted on
the carriage R, and passing under and partially around the adjustable grooved
pulley at the front end of the machine, extends to the rear of the extension,
over, partially around, and beneath the adjustable grooved pulley and thence
forward to the arın k¹ and is again secured thereto without cutting the twine from
the spool or bobbin which may stand on end on the floor below the carriago R.
The stands P, arms le¹ and pulleys and are adapted to be adjusted to
greater or less distance from the heddle needles for the purpose of adapting the
machine to make harness of different widths.
The carriage R is connected at will to the screw shaft H by means of a divided
nut, the two halves of which are arranged to be moved towards and from cach
other and the screw, H by the cam, disc R² the cam slots in which act upon pins
set in said half nuts, in a well known manner, said disc being rotated by the
handle R³.
The screw shaft H is mounted in bearings in the rear end of the frame B of the
head of the machine and the frame D of the rearward extension, and is connected to,
and receives motion from, the shaft F by means of the bevel gear wheels H', H',
as shown in Figure 4.
The carriage R is moved to the rear by the screw H and carries with it that part
of the rig-band to which the harness is being woven or knitted, at a speed,
corresponding to the accumulation of stitches formed upon the rig-band, suid
carriage being guided by the tie-rods D¹ D¹ upon which it has its bearings.
Qare hollow shafts mounted in bearings in the adjustable stands Q and cach
carrying at one end the spool having wound upon it a twine which I term the
the binding cord, and, which is lead therefrom through the hollow shaft Q and through
the two eyes in the finger Q3 secured to and projecting beyond the opposite end of
the shaft and thence to the last formed stitch on the rig-band, which latter also
passes through the centre of said hollow shaft Q in such a manner that at each

page_text: revolution of said shaft the binding cord
is wound around the rig-band O and
needle m as illustrated in Figures 23, 24 and 25.
The heddle retainer g is pivotted to the movable end of the curved lever gl
secured upon the rocker shaft g³ mounted in the stands g³, y³, and to which an
intermittent oscillating motion about its axis is imparted by means of the slotted
crank g, the lever g" and the cam g mounted upon the shaft G to which rotary
motion is imparted from the shaft F by means of the spur gear wheels g² and g³ as
shown in Figure 8.
The forked heddle eye retainer g is also connected at or near the middle of its
length to the movable end of the lever g, mounted loosely upon the shaft glo also
mounted in bearings in the stands g³ ³ as shown in Figure 3. The object of
connecting the heddle eye retainer g to the loosely mounted lover g' is to maintain
said heddle eye retainer in a perpendicular position or nearly so, during its upward
and downward movements.
The shaft g also has secured thereon the two knee shaped pushback fingers h
which serve to prevent the loops last formed around the rig-band and stitch
forming needles from being carried forward by said needles as they advance to
engage with new loops preparatory to drawing them through said previously
formed loops.
The successive pairs of loops drawn out from the heddle needles to the rig-bands
by the hooks j,j, and lifted therefrom by the hooks P, P are seized by the hooks of
the latch needles m, m, together with the binding cords 1, 2, and drawn through
the previously formed loops by the rearward movements of said needles which
engage only with one side of said loops for the reason that the rearward side of
each of said loops is raised to a higher level than the front portion or side, which
is caused by the form of the notch in the end of the hook P in which the end of
the loops rests, which notch is oblique to the axis of said hook and inclined to n
horizontal plane, as partially illustrated in Figures 23, 24, and 25 whero m is the
needle provided with the hook m' and pivotted latch lever m³,-0 the rig-band,-
the binding cord-Q the binding cord carrying finger, j,j, the loop carrying
books, P, the lifting hook,-n the previously formed stitch and n¹ the loop of
yarn from which the next stitch is to be formed.
The needles m, m, are firmly secured in the posts or studs n³, n³, adjustably set
in the slotted plates n³, n³ secured to or forming part of the rods n*, mounted
in bearings n, and adjustably connected to opposite ends of the cross-head T by
means of which and the slotted lever T₁ fulcrumed upon the stand no, and the
adjustable crank n' on the inner end of the short shaft G' a positive reciprocation
is imparted to the rods n', n*, and the needles m m (Figures 1, 2, and 3). The
object of these several adjustments is to adapt the machine to make harness of
different widths.
The shaft go has firmly secured thereon the arm gll to the movable end of which
is secured the shoe g¹ arranged to rest upon the upper heddle eye needle I or the
heddle eyes thereon, and to be raised intermittently therefrom by a rocking motion
imparted to the shaft g10 by the cam g¹³ on the shaft F' acting upon the lever g¹t
secured to the front end of said shaft g as shown in Figures 1, 2 and 3.
The two heddle needles I, I extend to the frame D of the rearward extension of
the machine and are secured by set screws o, o to the vertical plate O' which in
turn is firmly bolted to the rear end of the rectangular bar O' the forward end of.
which has formed thereon the pin o' which enters a hole in tho rear end of the
plate O³ and is connected by the bolt o³ to the carriage O' so as to be supported
thereby when it with the needles I, I are moved to the rear, for removing the
harness when completed.
The carriage O' is composed of two bars arranged parallel to each other one
above and the other below the guide or tie-rods D¹, D¹ and connected together by
two studs as shewn in Figure 9.
The lower heddle needle I is supported near its front end upon the forked
shoe O³ shewn in plan in Figure 14 and at another point in its length upon the

page_text: curved upper surface of the plate o³ secured to or forming a part of the car o' of
the carriage O' and projecting over the upper surface of the bar 0° all as shown in
Figures 11 and 12.
O is a bar also connected at its rear end by set screw of to the vertical plate 0¹
and having secured to its front end the forked shoe O' which rests upon the lower
heddle needle I and supports the front end of the upper heddle neodle as shewn in
Figures 11 12 and 13.
U is a bar firmly secured to, and projecting backward from the plate O¹ and
having mounted thereon suitable housings U, U₁, in which are mounted four pairs
of tension rolls p, p the upper rolls of which are drawn downwardly by the
springs p', pl acting upon the rods p², p' as shewn in Figures 17 and 20.
The bar O¹ is supported directly over the carriage O' by the rolls 0 mounted on
a stud set in the stand o secured to the side of the bar 06 the said truck or roll
resting upon the lower heddle needle directly above where the said needle rests
upon the curved upper surface of the plate o³ as shown in Figures 11 and 13.
The needles I, I and the bar 06 are made as light as is consistent with the
proper working of the machine so that the heddlo eyes may be easily moved along
the said needles, the yarns passing between said needles and the shoes 05, 07, and
between the lower needle and the plate o³ and roll oº.
U' is a slotted stand secured to the frame D and provided with the set screw q
having the handle q' by which the bar with the bar O¹, needles I; I, bar U and
housings U, U are firmly secured in fixed positions when desired, and by turning
said set screw a single half revolution all of the bars 0², 0% and U, the needles I, I,
the plate O' and the carriage O' may be released and moved to the rear sufficiently
far to withdraw the needles I, I, from tho harness when completed, the carriage O
being guided and supported in its backward movement by the tie rods D', D
The shaft G has its bearings in stand G³ bolted to the rear frame B of the head
of the machine and in the stand or bar G secured to the inner side of the frame D of
the extension, and has secured to its rear end the can r which acts upon a roll or
truck mounted upon a stud set in the lower end of the lever 73, the upper end
of which is a segment of a spur gear the teeth of which mesh into the teeth of the.
spur pinion mounted upon the rear end of the short shaft V having bearings in
the stand 8 and to which is coupled by means of the set screw 2, the leese-rod W
to which an intermittent oscillating motion is imparted by the combined action of
the cam r and the spring shewn in dotted lines in Figure 21.
The leese-rod W extends forward to a point just beyond the vertical plane in
which the loops are connected to the rig-bands and has its end bent to an angle to
its main body so that it serves to guide the loops connecting the heddle eyes with
the rig-band above or below said rod according as the bent part thereof is directed
downward or upward which operation is necessary in order to form the "leese"
80 called.
The leese rod W bas secured to its rear end the rectangular socket s¹ to receive
the end of the harness shaft when it is desired to introduce said shaft into tho
harness, which is readily done by simply loosening the thumb screw and pushing
the leeso rod W with said harness shaft through the harness towards the front end
of the machine till the leese rod has passed entirely out of the harness and the
harness shaft has taken its place, the forward end of the socket s¹ being gradually
reduced by curved surfaces to the size of the leese rod so as to prevent no
obstruction to the passage of said leese rod and socket between the yarns of tho
harness.
At the opposite side of the heddle needles is a rod W' corresponding to the
leese-rod W, except that its front end is not bent, that is to say it is not provided
with the socket 8 and is connected by means of the thumb screw a to the shaft V,
but is not designed to be oscillated The office of the said rod is to separate the
yarns leading from tho heddle eyes to the rig band upon that side of the machine,
'one half of which yarns are drawn over and the other half under the front end of
seid rod W in the operation of drawing out said yarns, forming the stitch and.

page_text: securing it to the rig-bands; it also serves as a convenient medium of inserting the
other harness shaft between the yarns of the harness, as before described in
connection with the leese rod.
S, S are two rig-band guides adjustably secured in the arms S' which in turn are
secured to the adjustable stands S², the said guides being composed of the main
body S and the steel plate & secured thereto by screws and having its inner end
turned downward thus forming in the inner ends of said guides L shaped slots 8³,
as shewn in Figure 15 between which turned down portion of the plate &³, and the
abutment formed by the upper portion of the inner end of the main body S, the
rig-band with the stitch formed thereon, passes.
The main body of said guide has a slots formed therein for the passage of the
latch needle.
These guides serve to keep the rig-bands at the exact required distance apart at
or near the point where the stitches are formed which unites the heddle loops to
the rig-bands.
To the rear side of the upper portion of the frame D are bolted the two
arms S3 S3 which extend backward therefrom and have set in their upper sides the
standards S' in which are set the horizontal spindles S, upon which are mounted
the spools S and S7, two of each, which contain the yarns from which the heddle
eyes and loops are to be formed.
The yarns from the spools S° pass downward therefrom through the ring-
weights 85, embracing and arranged to move up and down on the wires 8³, then
between the forward pairs of tension rolls p, p,-through the forked upright 8
along the groove in the upper side of the lower heddle neodle I and through the
eyes in the point of said needle, one upon either side thereof, and are drawn
backward along the outer edges of said needle and secured thereto in the rear of
the forked heddle retainer g
In like manner the yarns from the spools S7 pass downward therefrom through
the ring weights between the rear pairs of tension rolls, through the forked
uprights 87 and along the groove in the upper side of the upper heddle noedlo to
and through the eyes at the point of said needle, and are secured thereto as before
described.
X is the shipper lever mounted upon a fixed fulcrum and engaging by its forked
end with the sliding portion X' of the clutch and connected by its horizontal arm
to the upper end of the rod X, the lower end of which is connected to the lever X³
firmly secured upon the rocker shaft X' to the front end of which is also firmly
secured the treadle lever X having pivotted thereto the rod X. The upper end of
the rod X6 has formed thereon a handlo which projects above stand X7 through an
opening in which said rod passes and with the side of which a notch formed in said
rod engages when the clutch is thrown out of gear by pressing upon the treadle
lever X or pushing down upon the handle end of the rod X, the spring X³, serving
to cause such engagement of the rod X with the stand X7.
A spring X is attached to the horizontal arm of the shipper lever X in such a
manner that when the notch in the bed X is disengaged from the stand X' it will
cause the sliding part X' of the clutch to engage with the part formed with the
cone-pulley, thereby causing the shaft X to move about its axis and the treadle
lever X and the rod X to be moved upwards.
Y is a weighted elbow lever pivotted at t to the stand and provided with the
pin with which the pivotted catch lever engages to hold the weighted long arm
of the lever Y in a horizontal position as shewn in Figure 4.
X10 is a lever firmly secured upon the shaft X and provided with the horizontally
projecting pin t³, so arranged that when the clutch is in gear with the cam pulley E³
said pin will be in close proximity to the edge of the pendent arm of the weighted
lever Y and directly in its path of motion, so that a movement of the lever Y
caused by the falling of its weighted end will cause the clutch to be thrown out of
engagement and thus stop the machine.

page_text: The lower end of the catch lever is connected by the wire t to the lower end
of the lever to pivotted at u to the stand Z secured to the frame Dand is connected
at its upper cud to the lower end of the lever which is also pivotted to the
stand Zat u and is connected at its upper end to the lower end of the lever t'.
The said lever has its fulcrum at u³ and is provided with the laterally projecting
ears u³, u³, in bearings in which is mounted tho upright bar t in such a manner
that it may be turned or partially rotated in said bearings, and provided at its
upper end with a horizontally projecting plate to the lower edge of which engages
nt u* with a notch in the upper end of the lever t, and has secured thereto the
fingers us, u³ which are set just far enough apart to permit the free passage of the
yarns when when said yarns are of the proper regulation size. If however a knot
knob or other enlargement of the yarn is brought to said fingers it will not pass.
through the slit between them but will strike against them and thus vibrate the
series of levers 7, to and to in such a way as to draw upon the wire and remove
the catch t from beneath the pin t', when the weighted end of the lever Y will
fall causing its pendent arm to strike the pin 3 with sufficient force to operate the
shipping mechanism and disengage the driving pulley and thus stop the machine.
The fingers u, u are directly in the rear of the heddle needles I, I, and their
supporting plate O¹, and in order to permit the rearward removal of said bars and
needles said fingers must be removed from their path which can be done by raising
the bar until the plate to is disengaged from the notch in the upper end of the
lever t' and then turning it a half revolution in its bearings.
In the manufacture of harness in which the eyes are formed singly, one after
another, it has been a custom to knit the heddle-twines which lead from the
heddle-eyes to the rig-band, by a crotchet stitch consisting of a double-hoop drawn
within a double-loop, each double loop consisting of a binding-twine which is wound
loosely around the rig-band and a twine which connects the heddle-eye last formed
with a heddle-eye in the process of formation. In the completed harness this last
mentioned twine is a continuous twine folded on one side of the harness in a zig-zag
manner from heddle-eye to rig-band, back to the next heddle-eye and to the
rig-band again and so on through the whole harness. On the other side of the
harness, known as the knotted side, there is a similar continuous twine folded
in the same zig-zag manner from heddle-eye to rig-band except that the eyes
themselves are made from it by tying a knot. But on either side of the harness
each fold of the zig-zag twine at or near the rig-band, that is, each fold in the
zig-zag twine which is mid-way between two heddle eyes, is seized by a crotchet
needle or other suitable instrument along with the binding twine, and the two
twines are drawn as a double loop through the next preceding double loop which
has been formed in the same manner.
The drawing of one double loop through the preceding double loop tightens the
said preceding double loop and the zig-zag heddle twine is thus secured or knitted
to the rig-band.
Now, when in the manufacture of the harness the heddle-eyes are made in pairs,
or two are formed simultaneously, thero are, on each side of the harness, both
the knotted and the looped side, two zig-zag twines, one to connect the even
numbered heddle-eyes and the other to connect the odd-numbered heddle-eyes to
the rig-band; and in knitting these two zig-zag twines to the rig-band according
to this present invention both twines are seized, each midway between its heddle-eyo
which has been last formed and its leddle-eye which is in the process of formation,
and at the same time the binding twine which has been wound loosely around the
rig-band is seized and then the three twines are drawn together in the form of a
triple loop through the preceding triple loop which has been formed in the samo
manner, substantially as in the manufacture of the harness previously described,
the drawing of one triple loop through the preceding triple loop tightens the said
preceding triplo loop.

page_text: Referring now to Figures 26 to 31, illustrating the product of the machine
heretofore described; the rig-band is marked while b is the binding twino; c, e³
are odd-numbered eyes; e³, e', are even numbered eyes; and of these e¹ and e are
to be considered as the two eyes last formed, and e³ and e' are to be considered
as the two eyes in the process of formation, according to the preceding description,
although more strictly speaking, the knots of all four eyes are represented as tied,
and the heddle-twines t, t, might be described as respectively connecting the
alternate eyes e, e³, and e² e' of the last two pairs of eyes. The continuous zig-zag
twine connecting the odd numbered eyes is marked t, at many places while the
other zig-zag twine is marked t².
-
At the stage of operation shown at Figure 28 it will be observed that the two
heddle twines t', t, with the binding twine b forming a triple loop has been drawn
within a preceding triple loop which has been tightened.
At the stage of the operation shown at Figures 29 and 30 the triple loop
receiving the last triple loop has not been tightened.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
First. The rig-band guides S S provided with the L-shaped slots 8³ in their
inner ends, and the slots a' for the passage of the latch needles, substantially as
