I, WILLIAM BRIMFIELD, of Blue Anchor, Camden County, New Jersey, one
of the United States of America, Weaver, do hereby declare the nature of this
invention to be as follows:-
-
My invention relates to improvements in looms for weaving pipe fabrics, and
its object is to furnish a loom for weaving patterns or figures of any kind and in
any number of colors without the use of the perforated cards and complicated
mechanism heretofore used for such purposes.
In carrying out my invention I use a pattern chain consisting of a number
of slats placed transversely of the loom, that is at right angles to the warp
threads, which are furnished with outwardly projecting stops adjustable trans-
versely of said slats and longitudinally of the loom. The slats are arranged
preferably as an endless chain and are by suitable mechanism advanced consecu-
tively to the front of the machine where the several stops are adapted to engage
and move forward carriers which carry tubes through which the pile.yarn passes.
The tube carriers are placed side by side forming a row which extends from
one side of the loom to the other. Each carrier carries a series of tubes arranged
longitudinally of the loom, each tube being adapted to carry a thread of yarn.
As the slats are advanced the stops carried by the operative one engage and
move forward the several tube carriers that are in allignment with them, each
stop engaging and moving but one carrier. The distance that the carriers are
moved corresponds to the position of the stops on the slats. The further that the
stop is forward on the slat the greater the movement of the carrier, the further.
back the less the movement. Where stops are omitted there is no forward move-
ment given to the corresponding carriers.
The several tubes carried by the several carriers form two or more rows of
tubes which extend from one side of the machine to the other and preferably
the several rows of tubes carry each a different colored yarn. The stops upon the
slats are set to form a pattern from a painted pattern of the usual kind and they
can be changed from one pattern to another very quickly.
After the stops have moved the several carriers forward the tubes thus brought
into operative position are alligned and lowered beneath the inoperative tubes.
Grippers now engage and draw the yarn down beneath the tubes and a knife
severs the yarn which is drawn by the grippers through the warp threads when
the grippers release it and it is engaged and held by the warp and filling threads
of the fabric.
With suitable modifications the loom is adapted for weaving either single or
double faced pile fabrics.

I. WILLIAM BRIMFIELD, a Citizen of the United States, and a Resident of Blue
Anchor, County of Camden, State of New Jersey, United States of America,
Weaver, 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:-
My invention relates to an improvement in figuring machines for the produc-
tion of textile fabrics, and the object of my invention is to furnish a machine for
the production of pile fabrics which will, in connection with a loom, produce
such a fabric with the use of less yarn than is possible with the machines hereto-
fore in use, which will produce the fabric direct from the yarn without first
weaving the yarn in a chenille loom, which will automatically and exactly
reproduce any desired pattern to which the machine may be set, and which will
produce a. fabric at the same time of better appearance, cheaper, and of better
quality than is possible with the machines heretofore in use for such purposes.
In the accompanying drawings forming part of this specification and in which
similar letters of reference indicate similar parts throughout the several views:

of the fabric which are operated by the mechanism of the loom, not shown, in the
usual manner. e are yarn tube carriers which are carried in a guide f, best shown
in Figs. 3 and 4. The guide f is furnished with parallel grooves as shown to
receive and guide the carriers in their forward and backward movements and
the carriers, each of which can move independently of the others, are placed side
by side and extend across the whole front of the machine. Each carrier carries
a number of yarn tubes g, in the present instance seven, which number may be
increased or diminished as desired. The yarn tube carriers are preferably con-
structed of metal, the set carried by each carrier are placed one directly back of
the other and longitudinally of the loom, and the corresponding tube of each
set of tubes form a straight line transverse of the loom when in normal position.
The tubes of each transverse row of tubes carry, ordinarily the same color of
yarn and for purposes of this description they will be so described, and the tubes
of each longitudinal row carry yarn of different colors.

The frame o which carries the shaft k of the pulleys or cylinder j is carried by
the frame a of the loom and preferably upon rollers p, Figs. 2 and 3, in order
to overcome friction as much as possible. The frame o, the cylinder j, and the
chains and connected parts are moved back and forth as follows:

a lever u, Fig. 2, which is pivoted at and which is furnished with a friction
roller w which is engaged by a cam carried by cam shaft b. The upper arm of

the remaining carriers that have not
The distance that the carriers are moved depends upon the position of
stops n on slat m; if they be at the forward edge of this slat they will be moved
to their greatest forward position, if at the rear to their least forward position,
and an intermediate position will cause them to be correspondingly moved.
As the yarn tube carriers are moved forward the yarn tubes are moved with
them, and the distance that the carriers are moved determines which of the
several tubes carried by them will be brought to the working point.
The yarn tubes are furnished upon one side with two projections 3, 4, and upon
their upper end with a projection 5, all of which are best shown in Figs. 5, 6
and 11. Normally the projections 5 rest upon the top of a stationary guide (
and the projections 3 upon the top of a movable arm 7, Figs. 3, 4, 5 and 6, which
is carried by a vertical rod 20. The guide 6 is furnished with a notch 8 and the
arm 7 with a downwardly projecting finger or lug 9, best shown in Figs. 5 and 6.
The frame o having been moved forward and the stops n having engaged
and pushed forward the several yarn tube carriers until the desired tubes are in
line with notch S and lug 9, a cam 10, carried on cam shaft b, Fig. 2, causes
lever 11, Fig. 2, to fall. The outer end of lever 11 is connected to one end of a
ed 12 Figs. 1, 2, 3 and 4, the outer end of which is connected to a movable
rame 13 which is carried by and vertically movable upon rods or guides 14
arried by the main frame of the loom. As the lever 11 falls the frame 13 and
he parts carried by this frame fall with it and a lever 15, Figs. 3 and 4, which
pivoted on the frame 13 is lowered. 16 is a spring one end of which is attached
o the inner side of lever 15 and the other to frame 13. 64 is an adjustable stop
arried by loom frame a which is adapted to bear against the upper outer end
f lever 15 depressing the outer end of this lever when the frame is in its raised
osition and raising its inner end as shown best in Fig. 4. When the frame 13
lls the lever 15 falls with it and immediately the spring 16 commences to
raw down the inner end of the lever which carries a pin 17 which engages an
m or link 21 attached to a rod 22 which extends completely across the front
the machine and the lower end of which is sharpened as best shown in Figs. 5
d 6. The sharpened end or edge of this blade engages one of the teeth or
tches 23 formed on the top of each of the tube carriers e and brings the row of

page_text: varn tubes into perfect allignment. The teeth or notches 23 correspond in number
with the number of yarn tubes carried by each carrier e, and the distance of one
tooth from the next corresponds exactly to the distance from the centre of one
yarn tube to the centre of the next adjacent one, in other words the pitch of the
teeth 23 is equal to the pitch of the yarn tubes. Both sides of the loom are
furnished with the parts above described.
A further downward movement of frame 13 causes pin 17 to engage the bottom
of slot 18 in a connecting red 19 the lower end of which is attached to rod 20
which carries the arm 7. As soon as the pin 17 reaches the bottom of slot 18
it pushes down rod 19 which pushes down rod 20 which carries arm 7 and the
lug 9 on this arm engages projection 4 on the yarn tube which is in line with
it and the lug or projection 5 on the top of this particular tube entering notch 8,
the yarn tube is lowered as shown in Fig. 6.
The frame 13 having reached the end of its downward stroke the nippers 29,
Figs. 1 and 2, of which there is one for each yarn tube, are raised, passing
between the warp threads passing downward out of the tubes. The frame 13 is
now raised a distance equal to the length of pile required and stops, which
movements are given by the shape of the cam 10. When the frame 13 stops, a
cam 30 on the cam shaft b, through a lever 31 and link 24, draws arm 25 inward
and the upper end of this arm engages and moves in a slide 32 which carries a
roller 33 which engages a bell-crank lever 34 which through a link 35 is con-
nected to a slide 36 which carries one blade 37 of a shears blade 38 of which is
carried by the slide 32. The operation of slides 32, 36 causes the shears to cut
off the threads passing downward through the tubes and held by the nippers. As
soon as these threads are cut the cam 10 and connected parts raises the frame 13
and connected parts to their highest position and the several parts take position
as at first described.
While the frame 13 is rising the nippers 29 are being lowered and draw down
through the warp threads the cut yarn that they are holding, and when this
yarn has been drawn down such a distance that its ends will project equally on
each side of the warp threads it is released by the nippers, a shot of filling is
thrown in behind it by the loom and the reed 39, which is actuated in any con-
venient manner, beats it up as usual.
The mechanism for operating the nippers is as follows:
40, Figs. 2 and 7 is an arm upon which one jaw of the nippers are carried.
This arm is pivoted to one end of a link 41 which is pivoted at 42 to a bracket 43.
Each side of the machine is similarly equipped. 44 is a pivot carried by arm 40.
45 a lever depending from pivot 44 to the lower end of which is pivoted a link 46
the other end of which is pivoted to the upper end of an arm 65 the lower end of
which is pivoted to frame a at 47. The arm 46 is operated by a cam 48 on cam
shaft which operates to throw arm 46 in and out. The outward movement
operating to push rod 46 forward and to raise lever 45, arm 40 and the nippers,
and the inward movement to lower these parts.
The nippers are opened and closed as follows:
49 is a crank fast to pivot 44. 50 a link pivoted to end of crank 49 and to a
rod 51 which is connected to the movable jaw 52 of the nippers. 53 is an arm
attached to pivot 44. 54 a rod one end of which is attached to lower end of arm 53
and the other end to the upper end of a lever 55 which is pivoted at 47 to
frame a. 50 a cam which is carried on shaft 6 and which operates to throw
lever 55 in and out. When cam 56 throws lever 55 out the jaws of the nippers
are closed. When the lever 55 is moved in rod 54 pushes arm 53 forward,
rocks pivot 44, and causes crank 49 and link 50 to assume a position in line with
one another. This pushes out rod 51 and opens the jaws of the nippers.
The several cams on shaft b are so shaped and placed that the several move-
ments dictated by them will take place at the proper time.
The pattern to be formed in the fabric is first designed in the usual manner,
the stops n on the slats m are then set so as to correspond with the pattern, that

page_text: is the stops regulating the use of one color of yarn are all, preferably, on one
line on the slat, and the stops of each other color are all, preferably, on their own
particular line. The design is changed as desired by changing the positions of the
stops which can be moved in or out on the slat in order to bring any one of the yarn
tubes to the operative position as heretofore described. The slats and stops form
what may be called an adjustable card."
As has been described before the forward movement of the frame o causes the
stops to engage and move forward the carriers c so as to bring the desired yarn
tube to the operative position. As the carriers are moved forward their inner
ends, which form a hook 57, engage and move inward a bar 58 which slides upon
guides 59. After the yarn has been drawn out of the tubes 7 and cut off as
described, and after the frame 13 has been again raised to its original position,
the frame o is moved backwards and projections 60, Fig. 1, on this frame engage
the ends of bar 58 and draw it back and with it carriers e that have been moved
forward. The carriers e are thus returned to their first position. Upon the
backward movement of frame o pawl 2 engages one of the teeth of ratchet 1
turning shaft k and cylinder j and bringing a new slat m and its stops into
operative position in front of the cylinder.
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 :-
