PROVISIONAL SPECIFICATION.
Improvements in Apparatus for the Manufacture of Rugs or other
Looped or Pile Fabrics.
I, MOSES PULLEN of Lower Cote Fixby, Rastrick in the County of York,
Gentleman, do hereby declare the nature of this invention to be as follows:-
-
The object of my invention is to construct a machine for the manufacture of
rugs or other looped or pile fabrics, so that the said loops or pile is stitched or
securely attached to the foundations of such rugs, automatically and simultaneously
with the manufacture of the same.
Upon a suitable frame I fix a square or other suitable rod or slide, upon this
rod or slide is a carriage, secured to which is an ordinary reversible sewing
machine driven by suitable gearing, pulleys, cords, or belts, from the rod or shaft
before described.
Also secured within the machine frame and driven by suitable gearing on the
before described rod or shaft, is an automatically reversible screwed rod or shaft,
this screwed shaft when operated moves the carriage (upon which is the sewing
machine) backwards and forwards across the width of the machine frame, at each
movement the needle stitches a fresh series of loops across the whole width of the
fabric, but this screwed shaft may be adjusted to reverse as desired, according to
the width of the fabric being woven, this shaft is reversed by tappet, cam and
catch or finger at each end of the machine frame.
Underneath the arm of the sewing machine I place a suitable roller carrying
the foundation, the foundation passes through the machine over a card roller on to
a beam roller, the card roller each time a loop is formed is moved by means of a
ratchet wheel and lever, drawing the foundation forwards to allow for another row
of loops being formed and stitched.
The warp or pile may pass from a creel or from bobbins in any suitable position,
through a reed or perforated bar fixed underneath the sewing machine armı,
preferably the full width of the rug being woven; also in any suitable position I
place preferably two vertical bars, similar in width to the rug, between these two
bars the needle of the sewing machine as it travels on the rod or slide works and
stitches the threads or warp on to the foundation; after such warp has been
stitched the two bars before described are raised to allow a horizontal bar to pass
underneath to form the loops or pile, these bars are moved by means of cams, levers,
catches or other suitable mechanical means.
When the loop is formed the horizontal bar recedes to its original position and
the vertical bars lowered on to the loop, so holding same whilst being stitched as
before described.
The loops may be cut if required by means of a knife passing within the said
loops in any suitable manner simultaneously during the manufacture of such rugs
or other pile fabrics; or they may be cut after the rug is woven.

page_text: of the lever G', the pinions carried by this lever are so brought into gear with the
pinion G, as to alternately reverse the motion of the screwed shaft E.
For forming the loop or pile, I employ at one end of the machine a second
carriage or bracket H, upon one side of which is a gear wheel H', loose upon a
short shaft H, and driven by means of a small gear wheel D' upon the shaft D;
cast upon or attached to the gear wheel H is a ratchet wheel H³, gearing with
which is a spring catch H³, attached to this spring catch H³, is a stud H, which
passes through a slot T¹ in a disc T, and rests upon an inclined plane or pirotted
lever J, the motion of the gear wheel H¹ pressing the stud upon the inclined plane,
lifts the spring catch clear of the catch wheel, allowing the same to revolve until
(the sewing machine having reached the end of its traverse) the cams R and R¹
operate the mechanism before described, and the notched cam presses back the
lever or catch J, operating the lever J, which moves the inclined plane clear of
the catch which immediately engages with the catch wheel H2, so moving the discs
L and T one revolution, when the stud of the catch again comes in contact with
the inclined plane or lever J, lifting the catch clear of the ratchet wheel until the
sewing machine has reached the end of its traverse, and the cams R or R' acting
upon the fingers R³ or R* as the case may be, operate the notched cam J2 as before
described.
As the discs Land T make one revolution, a connecting link L' attached to one
end of a pivotted lever L' operates the said lever L2, which by means of connecting
rod L operates a suitable horizontal bar M, within a suitable slide L', employed
for forming the loop in manufacturing the aforesaid rugs, see Figs. 2, 4, and 5,
another connecting rod L is attached to the pivotted lever L2 at one end, (the
other end being secured to a bracket L' attached to the hinged holding down
bars N) is employed in conjunction with an inclined plane M₁ attached to each
end of the horizontal bar M, for raising and lowering the bars N, this is effected
as the horizontal bar moves forward to form a fresh series of loops. The bar M
in forming the loops bears against the warp A', unwinding same from the beam
roller C, until the bar has reach the end of its traverse and the loop is formed
see Fig. 5, it then recedes upon which the holding down bars N fall or drop upon
the pile or loops, holding them in position whilst being sewn or stitched.
any
The warp or pile A' may pass from a creel, bobbins, or from a beam in any
suitable position through a reed or perforated bar O, fixed underneath the sewing
machine arm, preferably the full width of the rug being woven, also in suitable
position I place preferably the two holding down bars N, similar in width to the
rug, between these two bars the needle B' of the sewing machine works and
stitches the threads or warp on to the foundation, as it travels on the rod or slide D
and shaft E.
When the sewing machine has traversed the whole width of the pile, the said
machine is preferably stopped with the needle raised or at the top of its stroke, so
as to allow of the needle moving clear of the pile or rug being woven, and to
allow the horizontal bar to move forward and form a fresh series of loops, this
being accomplished by means of a pivotted lever N' upon a suitable stud or shaft N'
coming in contact with a bracket or inclined plane N³ which presses back the said
lever N¹, and operating a strap fork N, throws the driving band or belt of the sewing
machine upon the loose pulley F2 of same, simultaneous with this movement a
pivotted spring catch P, operated by means of a forked pivotted lever P' upon the
aforesaid shaft N2 engages with a recess in the fly wheel P2 of the sewing machine,
at the same time a brake P³ bears against the fly wheel and stops the same while the
needle is at the top of its stroke, immediately the traverse is reversed and another
series of loops are formed, the catch P is released and sewing machine stitches the
series of loops or pile.
Simultaneous with the revolution of the disc L, the disc T operates a con-
necting rod, crank or lever S¹ and pivotted fulcrumed lever T' connected to a
horizontal knife S, which, (when the horizontal bar M has formed the loops) cuts
the same, the cutting edge of this knife moving within a suitable groove at the

page_text: front edge of the horizontal bar M, (see Fig. 5.). After the loops are cut the
holding down bars drop upon the same, as before described and hold them in position
until they are stitched.
After each series of loops has been stitched and cut, and a new series is about
to be formed, the foundation B¹ is moved the requisite distance by means of a
cam or finger W upon the shaft K, operating upon an inclined plane or pivotted
lever V, which operates a second pivotted lever V₁, connected to and operating
the ratchet Y, engaging with the ratchet Y, upon the shaft of the beam carrying
the rug when weven, this ratchet operating and moving the ratchet wheel one or
more teeth as desired at each reversal of the screwed shaft E. For manufacturing
rugs or other pile fabrics with uncut loops, I dispense with the knife S and
mechanism for operating same, the loops being formed by the mechanism before
described.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The construction of an apparatus or machine for the manufacture of rugs or
other pile fabrics, so as to automatically form, cut and sew a series of loops or pile
upon the foundations of such rugs or other pile fabrics at one operation, in the
manner such as shown and described.
2. The use and employment of a shaft D, screwed shaft E, horizontal bar M,
holding down bars N, shaft K, sewing machine F and knife S, all operated in the
manner and for the purposes, such as shown and described.
3. The use and employment of a travelling sewing machine for stitching the
loops or pile upon the foundation of rugs or other pile fabrics, substantially as
shown and described.
4. The spring catch Pengaging with a catch or notch in the fly wheel P', in
combination with the improved machine operated in the manner, such as shown
and described.
5. The general arrangement and construction of apparatus in the manner and
for the purposes substantially such as shown and described.
