of this invention to be as follows:-
At the
Each machine consists of the following parts:-Two end standards connected by
one longitudinal tie bar, supported by one or more intermediate standards, the tie bar
and standards have bearings secured to them to carry the following parts.
front of the machine we place a hand shaft provided with driving pulleys and a
fly wheel, the hand shaft carries a pinion wheel gearing into a toothed wheel on a
cam shaft, or the two shafts may be connected by a strap, above which are three
rocking shafts, the lower one carries arms which support a sinker hook bar provided
with the requisite width of sinker hook leads, each arm forms the upper portion of a
three armed lever, the two lower arms carry trucks operated by a cam and counter
cam.
Bearded needles slide vertically between the sinker hooks, the needles being cast
in leads secured to a needle bar, the lower edge of which is carried by the upper
ends of four or more vertically slotted slides each of which clip square blocks
bored out to receive the cam shaft, and sinker hook bar rocking shaft, each
slotted slide carries two trucks one above and the other below the cam shaft, one
cam actuating both trucks, by this means we obtain a direct vertical action of
the needles without vibration. Above the sinker hooks the front edge of a presser
bar lies carried by the upper ends of three or more arms rocking upon a shaft,
the lower end of each arm carries a truck operated by the cam on the cam shaft,
each truck being held to its cam by a spring.
The machine is provided with a work roller or rollers operated in the usual way.
At the back of the sinker bar shaft is a shaft provided with truck bearing levers operated
by cams on the cam shaft the shaft carries levers and links to operate two parallel
vertical racks which are thrown alternately into and out of gear with a spur wheel cut

page_text: on the end of one of a pair of parallel horizontal screws, which are geared together and
lie above the needles, and between which threads are traversed right and left, the
lower ends of the racks are hinged upon the inner end of a V shaped lever carrying
two trucks operated by a cam and counter cam, the two screws are traversed reversely
to each other by two rocking levers operated by cams.
The two screws lie in bearings at each end and intermediately if required, the end
bearings are carried by the lower ends of two levers attached to the ends of a T shaped
bar nearly the length of the machine, this bar rocks in bearings on the end standards,
the shaped bar is provided with bearings for two parallel screws which revolve
reversely to each other, being driven by toothed gearing operated by a toothed wheel
on the cam shaft, the screws drive a number of hanging bars reverse ways, half the
bars moving on the front, and the other half on the back of the T shaped bar, each
hanging bar carries a number of cops, spools, bobbins or beams, from which threads
are supplied to the needles, each thread is passed through one or more sleys attached
to each of the hanging bars, the threads are traversed over one side, round one end,
over the other side and round the other end of a rest bar, pendent from the T shaped
bar before named, each thread as it arrives at the end of its traverse is transferred
from either screw to the other by a picker at each end actuated by levers and cams.
By employing a machine constructed as above described, we are enabled to make
traversed warp fabrics at a greater speed than heretofore.

Each of the above described figures are severally referred to hereafter and the
corresponding parts are indicated by the same letters where necessary.
Each machine consists of the following parts, see Figures 1, 14, 1, 2, 3 and 4.
Two end standards A A. connected by a longitudinal tie bar A', an upper tie rod A²,
and a back tie rod A³, the standards have bearings secured to them to carry the
following parts. At the front of the machine we place a hand shaft A+ provided
at the left end with driving pulleys and between the standards with one or more
hand wheels A³, for the use of the attendant, portions of the shaft at Figures 3
and are broken away to show more clearly certain cams and levers behind it,
the shaft carries a pulley A in line with a pulley A secured on the left end of
a cam shaft B, the two shafts may be connected by a helt passed round the
pulleys, or the connection may be made by toothed wheels.
Above the cam shaft are two shafts C and E which rock in bearings on the
end standards, the shaft C carries two arms C which support a bar (provided
with the requisite width of sinker hook leads C3, one of the arms forms the
upper part of a three armed lever, the two lower arms of which carry trucks, the
front one being operated by the sinker cam 7, and the back one by the counter
cam 6, see Figure 16.
Bearded needles slide vertically between the sinker hooks, the needles being cast
in leads and secured in the usual way to a needle bar D, see Figure 9, the lower
edge of which is carried by the upper ends of two vertically slotted slides D¹
each of which clip two square blocks D, the lower ones receive the cam shaft B, and the
upper ones the rocking shaft C, each slide carries two trucks, one above and the other
below the cam shaft, the cam 5, actuating the left slide, and the cam 9 the right slide,
see Figure 15, by which means we obtain a direct vertical action of the needles with-
out vibration. Above the sinker. Looks the front edge of a presser bar E', lies carried
by the upper ends of two arms E2 which rock with a shaft E, the right
arm projects below the shaft E, and carries a truck operated by the cam 8
see Figure 16, the truck is held to the cam by the upper end of a spring E³,
being hooked on to the lower end of the arin, the lower end of the
spring being hooked on a rod projecting from the front of the tie bar A' shown at
Figure 5. The front of each standard forms a bearing for the axle of a work
roller E (shown only at Figure 1,) operated in the usual way. Upon the shaft E see
Figures 3, 5, 6, 9, and 11, two levers F and F rock, each lever carries a truck at its
lower end, and is hinged to a link at its upper end, the front end of the link of the lever F,
is hinged to a vertical rack lever F3; and the front end of the link of the lever F", is
hinged to a vertical rack lever F, the tracks of the levers F and F are held to their
cams by springs shown at Figure 6, the cam 10 see Figure 17, operating the lever F,
and the cam 11, operating the lever F1 the rack levers F3 and F, are hinged upon an
axle projecting from the left side of the upper end of a V shaped lever F, rocking
upon an axle secured in the right end standard, the lever F carries two trucks the
lower one being operated by the cam 12, see Figure 18, to lower the rack levers and
the upper one by the cam 13 to raise the rack levers. The racks being alternately
moved into and out of gear with a spur wheel G³, see Figures 9 and 11, cut on the

page_text: front one of a pair of parallel horizontal screws G, which are geared together at
their left end, see Figure 12, the screws lie in a bearing G2 at the left end and a
double bearing G³ at their right end, make a portion or the whole of a revolution at
each course, when both screws are nearest the front of the machine the back rack F
as it falls moves the front screw with the spur wheel G₁ portions or the whole of a
revolution and the front rack F³ as it rises moves the screw and spur wheel a corre-
sponding portion both screws moving simultaneously by being geared together at the
left end by toothed wheels G shown in end view at Figure 9, such movement of the
screws cause threads placed between them to be reversely traversed right and left.
The screw bearings are carried by the lower ends of two levers projecting from the
underside of the ends of a T shaped bar H nearly the length of the machine between
the standards, the lower end of each of the two levers is connected to the front end of
a link H, the back end of which is hinged to an arm secured on a shaft. H13, which
rocks in bearings secured to the standards at the back. The ends of the bar H form
bearings for the back screw of a pair of parallel screws H3 and H³ which revolve
reversely to each other, being driven by toothed gearing shown only in section at the
right of Figure 3 the ends of the front screw H2 revolve and rock in bearings
secured to the standards the left standard is slotted to allow of the rise and fall of the
left end of the back screw H³ as shown by dotted lines at Figures 1, and 14, the
toothed gearing is actuated by a toothed bevel wheel on the right outer end of the cam
shaft, the left ends of the two screws are geared together by two toothed wheels I
outside the left end standard.
The rocking of the bar H the two screws H2, H3, and the lower parallel screws their
bearings and the levers carrying them are effected by a link H see Figure 1B
being hinged to a bracket Hat the back of the arm carrying the bearing G² and
at the front to the upper end of a three armed lever H", the lower arms of which
carry two trucks the front one being actuated by the cam 1, and the back one by the
cam 2, shown at Figure 15. The underside of an intermediate portion of the bar H
projects downwards and forms an upper round ended race below which two
arms project terminating in a lower race H³, portions of these races are shown,
at Figures 5, 7, 8, 9 and 10.
These races carry a number of hanging bars H the heads of which slide round
the race within a parallel sided circular ended iron belt E' carried by the lower
ends of four brackets having their upper ends secured to the top flange of the
bar H, the lower ends of the hanging bars are kept close to the race H by a flexible
steel band H surrounding them, the bottom of each bar carries a double sley both
flanges of which are perforated with fourteen holes through which threads are
passed from cops, spools, bobbins, or beams, above the sleys, carried by the hanging
bars forming two rows reversely traversed, only a few of the bars shown in the
drawings, but as many are employed placed side by side as will entirely cover the
sines and ends of the races.
At Figures 2 and 3 the front portion of the band He is broken away to show the
race H, each alternate hanging bar has a stud projecting from its top "shown at
Figures 5, 7, and 8" which engages with one or other of the screws H², or H³, by
which the whole of the bars are successively traversed along the front of the races,
round the right ends, along the back and round the left ends continuously, the
threads they carry being equally spaced along the front and back in two rows, kept.
apart by a rest bar K placed between the screws G, the rest bar is capable of adjust-
ment vertically and is held by two arms K' secured to the underside of the race H³,
see Figures 2, 3, and 10. The front screw G at its right end, and the hack screw at
its left end are turned down and screw threaded to receive two lock nuts, to adjust
the screws with respect to each other, the outer nut on each screw is pressed upon by
the upper end of a traversing lever L, which rocks in bearings secured to the
standards, the lower end of the lever to the back screw being operated by the cam 3,
and the lever to the front screw by the cam 15, the reverse end of each screw being
pressed by a plate spring L' secured to the underside of the bearing above it see
Figures 2, 3, 11 and 12.

page_text: Each thread as it arrives at the end of its traverse as it slips over the end of the
rest bar K is transferred from either screw to the other by a pair of picker plates M,
each pair being secured to the upper end of a rocking lever M' shown in plan and
front views at Figures 25 and 24, the lever at the left end being operated by the cam 4,
and the lever at the right end by the cam 14.
Having now described the several parts of the machine seperately, we will describe
the combined movements of the operating instruments while making one course of
work.
The threads being in the position shown at Figure 10 between the rest bar and
the two screws, are rocked to place the front threads at the back or beard side of the
needles, while there the front screw is traversed one or more needles to the right and
the back screw one or more needles to the left, the screws, rest bar, sleys, and spool
bars, are then rocked to pass both rows of threads through the needles to the front of
the machine, while there the screws make portion or the whole of a revolution
thereby traversing the front threads to the right and the back threads to the left in
the screws, but while the screws are being so moved, they are traversed by their end
levers, the front screw one or more needles to the left, and the back screw one or more
needles to the right, both rows of threads being then passed to the back through the
same division of the needles as when passed to the front. In conjunction with the
above movements the needles, sinkers, and presser bar are operated in the usual way,
the needle bar rising and falling at each course, the sinkers move back to allow the
work to be knotted over the needle heads, the sinkers then move to the front while the
needles are down, to hold the work down as the needles rise to their highest position
to receive the threads for the next course, the right end thread of the front row at
each course is pressed by the right pickers into the back screw after it has been
carried by the partial revolution of the front screw clear of the right end of the rest
bar, the left thread of the back row being pressed by the left pickers into the front
screw after it has been carried by the partial revolution of the back screw clear of
the left end of the rest bar, such combined movements being repeated at each course.
By employing machines constructed and operating as above described, we are enabled
to make traversed warp fabrics at a greater speed than heretofore.
Having now particularly described and ascertained the nature of our said Invention
and in what manner the same is to be performed we declare that what
claim is :-
