WEAVING BACKS, BAGS, PILLOW CASES, PILLOW SLIPS, AND OTHER TUBULAR
ARTICLES,"
In machinery or apparatus for weaving sacks, bags, pillow cases, and other
tubular articles in one piece without seams, the warp is divided into two portions,
one of which is to form one side of the article, and the other, the other side, and a
shed is pulled in each portion alternately, as is well understood. When the cloth
is to have a twill, satin or other fancy face, each part of the warp must have the
requisite number of healds, acted upon by correspondingly arranged tappets, to
produce the desired effect.
When the desired length of tubular fabric has been produced, and the upper and
lower warps or portions have to be united or interwoven for a short distance to
produce a closure of the tube that shall correspond to the bottom seam of a sewn
sack, a part of each portion of the warp has to be raised at each shed, and to effect
this we provide an extra tappet or pair of tappets, which is, or are inoperative
during the weaving of the bottom tubular portion of the article, but is put into
gear with the healds at suitable periodic intervals by means of a lever, operated
through the agency of a wheel, or train of wheels, in connection with the fluted

page_text: beam. The action of the lever, and consequently the length of the articles, may be
varied by means of change wheels, and the weaving of articles of any desired
length effected, without the use of jacquard mechanism or of a dobby.
According to one method of carrying out our Invention a wheel, keyed on the
end of the fluted beam shaft, drives a second wheel whose circumference is
calculated according to the desired length of the article to be manufactured. This
second wheel carries a snug, which, once in every revolution, comes in contact
with a snug on the end of a rod, connected by a second lover to a sliding bar. The
office of this sliding bar is to put a connecting rod, attached to a lever on one of
the jack rods, into gear with the tappets that operate the henlds during the weaving
of the closure of tube, every time that the snug on the wheel comes into contact
with the snug on the rod. This pair of tappets has two treadles united at their
free ends by a strap passing over a pulley. During the weaving of the tubular
part of the article these two treadles work idly. Projecting from one treadle is a
etud which engages with a book on the end of the aforesaid connecting rod when
the latter is pushed into gear with it by the action of the above mentioned snug.
The snug and the acting treadle are so arranged with relation to each other that
the sliding rod makes its motion at the time when the engagement of the hook
and the stud can be easily effected.
As soon as the connecting rod is hooked to the treadle it tightens the drag
chain or strap on the warp beam, and maintains the extra pressure so long as the
two warps are being woven together to forin the end or bottom of the tubular
article; this weaving continues until the snug on the wheel passes out of contact
with the snug on the rod, when the hook is drawn off the snug and the tubular
weaving is recommenced.
The circular or tubular shapo of the article in process of manufacture results
from the drafting of the threads through the eyes of the heald and the arrangement
of the tappets.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed

WEAVING SACKS BAGS, PILLOW CASES, PILLOW SLIPS, AND OTHER TUBULAR
ARTICLES
In machinery or apparatus for weaving sacks, bags, pillow cases, pillow slips,
and other tubular articles in one piece without seams, the warp is divided into
two portions, one of which is to form one side of the article and the other the 40
other side, and a shed is pulled in each portion alternately as is well understood

page_text: When the cloth is to have a twill, satin or other fancy face each part of the
warp must have the requisite number of healds, acted upon by correspondingly
arranged tappets to produce the desired effect.
When the desired length of tubular fabric has been produced and the upper and
lower warps or portions have to be united or interwoven for a short distance to
produce a closure of the tube that shall correspond to the bottom seam of a sewn
sack, a part of each portion of the warp has to be raised at each shed, and to effect
this we provide an extra tappet or pair of tappets which is inoperative during the
weaving of the tubular portion of the article, but is put into gear with the healds
at suitable periodic intervals by means of a lover operated through the agency of a
wheel, or train of wheels in connection with the fluted beam. The action of the
lever and consequently the length of the articles may be varied by means of
change wheels, and the weaving of articles of any desired length effected without
the use of jacquard mechanism or of a dobby
Referring to the accompanying drawings, Fig. 1 is a side elevation of so much
of a loom as is necessary to illustrate our invention; Figure 2 is a front elevation
of the same, and Fig. 3 is a view showing the means whereby the treadles for
weaving the plain portion at the end of a tubular article are put in connection
with the healda.
A wheel A keyed on the end of the fluted beam shaft B drives a second wheel C
whose circumference is calculated according to the desired length of the article to
be manufactured.
This second wheel carries a snug D, which once in every revolution comes in
contact with a snug E on the end of the rod F which is connected by the lever G
to a sliding bar H.
The lever G and the bar H are not pivotted together but are merely connected
by a spring H' so that under certain circumstances one can make its movement in
advance of the other.
The office of this sliding. bar is to put the connecting rod I attached to the
lever. V on one of the jack rods W into gear with the tappets O, S that operate
the healds during the weaving of the closure of the tube, every time that the snug
on the wheel C comes into contact with the snug on the rod F
This pair of tappets has two treadles L, R, united at their free ends by a strap P
passing over a pulley Q. During, the weaving of the tubular part of the article
these two treadles work idly. Projecting from one treadle (vis L) is a stud M which
engages with a hook U on the end of the aforesaid connecting rod I when the
latter is pushed into gear with it by the action of the snug D. The snug and the
acting treadle are so arranged with relation to each other that the sliding rod
makes its motion at the time when the engagement of the hook and the stud can
be easily effected
As soon as the connecting rod is hooked to the treadle it tightens the drag chain
or strap 6 on the warp beam ƒ and maintains the extra pressure which is trans-
mitted through the spring d so long as the two warps are being woven together to
form the end or bottom of the tubular article; this weaving continues until the
snug on the wheel passes out of contact with the snug on the rod, when the
hook U is drawn off the stud M and the tubular weaving is recommenced.
When the hook is in gear with the stud the healds 1, 2, 3, 4 are raised to the
position shewn at a by means of the lever X and the warp threads which pass
through the said healds forming the underside of the fabric are lifted to the level
of top warp which forms the overside of the fabric and passes through the
healds 5, 6, 7, 8, whereupon the two warps are woven together for a short distance
until the bottom or closure of the tubular article is completed.
The circular or tubular shape of the article in process of manufacture results
from the drafting of the threads through the eyes of the healds, and the arrange-
ment of the tappets, Y and Z will be understood from the following description
of diagram No. 1 and patterns Nos 1 and 2. Diagram No. 1 represents the threads

page_text: for pattern No. 1 which anid pattern shows the action of the tappets upon the
healds whilst the tubular portion is being woven.
The squares in patterns Nos. 1 and 2 marked black represent the healds up-
the blank squares or spaces represent the healds down at their respective picks
(eight picks to the pattern) as shewn by pattern No. 1 the healds 1 and 2 are
down, and 3, 4, 5, 6, 7, 8 are up for the first pick; for the second pick 1, 2, 3, 4,
7, 8 are down and 5 and 6 up-and so on throughout the diagram.
Pattern No. 2 represents the action of the tappets when the closure of the tube
is required.
As shewn the healds 1, 2, 3, 4 in the second pick are operated upon by the
tappets O, S through the agency of the rod I alternately throughout the diagram
the remainder as indicated in the diagram, are operated upon by their respective
tappets.
Having described the nature of our said Invention, and the manner of carrying
it into practical effect wo would have it understood that what we consider to be
novel and original and therefore claim as the Invention secured to us under the
herein before in part recited Letters Patent is
1. In a machine for weaving sacks, & other tubular articles the combination
with an endless pattern surface of a tappet or tappets put, by the action of the
said pattern surface, in & out of gear with one or more of the jack rods to cause i
the top and bottom warps to be woven together at the proper places to form the
closure of the tubular article, substantially as described.
2. In a machine for weaving sacks and other tubular articles the combination
with the mechanism that operates the healds during the weaving of the closure of
the tubular article of means for increasing the friction on the warp beam,
substantially as described.
3. In a machine for weaving sacks and other tubular articles the use in combi-
nation with tappets such as O. S. and treadles L. R, of a wheel C with snug D, a
rod F with snug E, lever G, sliding bar H guide J, connecting rod I spring d
and strap e arranged and operating, substantially as described for the purpose set
forth.
In witness whereof I the said Walter Briggs have hereunto set my hand
and seal this thirteenth day of December, in the year of our Lord one
thousand eight hundred and eighty two.
