IMPROVEMENTS IN LOOMS FOR WEAVING." A communication from abroad by
Stephen Greenwood, of Lodz, in the Kingdom of Poland, Weaving Overlooker.
This Invention relates, firstly, to improved apparatus for taking up the cloth as
woven.
Secondly. To improved apparatus connected with the operating the treadles and
healds, and to improved construction and arrangement of treadles so as to give
uniform tension or pull. Taking up apparatus constructed according to this Inven-
tion comprises an ordinary cloth roller or cloth beam, carried by the side frames of
the loom, and free to revolve easily upon its axis. The positive roller or emery
roller rests upon the cloth roller or upon the cloth contained on the cloth roller.
The axis of the second mentioned roller is guided by radius slot holes, in which its
axis rises as the cloth roller fills with cloth and becomes of greater diameter. A
guide stretching bar or rod is placed (by preference) behind the positive roller, the
cloth as woven passing over the breast beam under the guide stretching bar or rod,
thence over the positive or emery roller" to and around the cloth beam or cloth
roller.
The axis of the ordinary catch wheel serves as the centre of radial motion of a
casting or bracket carrying the gear, the other end of which casting spans or clips
the axis of the positive or emery roller." The slot within which the axis of the
"

page_text: latter moves being of curvature struck from the axis of the catch wheel as a radius
centre.
In the treading the heddles the hooks of the heald shaft are dispensed with, and
in substitution small rollers or runners are employed over which the straps or cords
are passed connecting them to the treadles and balance roller, thereby allowing the
'heddles to adjust their respective tensions and securing equality to each thread of
the warp.
The treaddles are so constructed as to secure uniform and direct central pull on all
the treadles alike. This object is secured by cranking, curving, or bending the end
of one treadle, the end of the other treadle being straight in itself, but the treadles
are at a slight angle to each other.

"IMPROVEMENTS IN LOOMS FOR WEAVING." A communication from abroad by
Stephen Greenwood, of Lodz, in the Kingdom of Poland, Weaving Overlooker.
This Invention relates,-
Firstly. To improved apparatus for taking up the cloth as woven.
Secondly. To improved apparatus connected with the operating the treadles and
healds; and to improved construction and arrangement of treadles so as to give
uniform tension or pull.
Taking up apparatus constructed according to this Invention comprises an
ordinary cloth roller or beam carried by the side frames of the loom, and free to
revolve easily upon its axis. The positive roller or "emery" roller rests upon the
cloth roller or upon the cloth contained on the cloth roller. The axis of the second
mentioned roller is guided by radius slot holes, in which its axis rises as the cloth
roller fills with cloth and becomes of greater diameter. A guide stretching bar or
rod is placed (by preference) behind the positive roller, the cloth as woven passing
over the breast beam, under the guide stretching bar or rod, thence over the
positive or emery" roller to and around the cloth beam or cloth roller.
"
The axis of the ordinary catch wheel serves as the centre of radial motion of a
casting or bracket carrying the gear, the other end of which casting spans or clips
the axis of the positive or emery" roller, the slot within which the axis of the
latter moves being of curvature struck from the axis of the catch wheel as a radius
centre. In the treading the heddles the hooks or fixed points of the heald shaft are
dispensed with, and in substitution small rollers or runners are employed, over
which the straps or cords are passed connecting them to the treadles and balance
roller, thereby allowing the heddles to adjust their respective tensions and securing
equality to each thread of the warp. The treadles are so constructed as to secure
uniform and direct central pull on all the treadles alike. This object is secured by
cranking, curving, or bending the end of one treadle, the end of the other treadle
being straight in itself, but the treadles are at a slight angle to each other.
Such being the nature and object of the Invention I will now describe the same
in detail, and in order that the Invention may be clearly understood have hereunto
annexed three Sheets of Drawings illustrative thereof, and have marked the views
with figures and letters of reference.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 shows outline of frame work and form of necessary slots therein; Fig. 2, a
view (detached) of casting for carrying emery or rough roller and necessary gear;
Fig. 3, elevation of the apparatus complete with cloth and emery roller in position.
At A is the ordinary cloth roller or beam carried by the side frame B, and free
to revolve upon its axis C; the positive or emery roller D rests upon the cloth,
the axis of the roller D being supported within and guided by the slot E, and in
which such axis rises as the cloth roller A fills with the cloth; F is a guide
stretching bar or rod, the cloth H as woven passing over the breast beam J, under
the guide bar or rod F, thence over the roller D to and around the roller A; G is
the axis of the ordinary catch wheel, which axis serves as the centre of radial
motion of a casting or bracket K; the latter carries the toothed wheels X for
driving the positive roller D, and keeping such wheels in gear as the positive roller
is raised by the filling of the cloth roller A.
The other end of the casting K. clips or spans the axis of the "positive" or emery
roller D, the slot within which the axis of the roller D moves being of curvature

page_text: struck from the axis G. The dotted lines x, Fig. 2. show ordinary gearing for
driving the positive roller, no springs or weights being necessary in connection
with the letting off motion above described.
Figs. 4, 5, and 6, Sheet 2, show the application of straps or cords K¹, K¹, attached
to the heald staves L, L, L, L, and passing over the rollers or runners M, M, M, M,
the axial pins of the runners being attached to the straps N, N, and "lamb" and
links P, P, of the treadles and balance rollers R, R. The use of the cords K', K¹,
and runners M, M, ensure the automatic adjustment of tension upon each thread of
the warp.
The treadles are constructed as shown by Figs 7 and 8, one being cranked or
curved as at S, the other, T, having its termination within the curve of the treadle S,
the treadles being placed at a slight angle to each other so as to secure uniform and
direct central pull alike on all the healds.
Having thus described the nature and particulars of this Invention, together
with the manner in which the same is to be performed or carried into practical
effect, I would have it understood that I claim,-
Firstly. The use of the casting K in combination with the cloth roller A and
positive roller D, whereby as the positive roller rises the casting K is moved upon
its fulcrum G, acting in manner and for purpose described.
Secondly. The use of the rollers or runners M, M, in combination with cords
K, K, and heald staves L, L, in manner and for purpose described.
Thirdly. I claim the construction of treadles S, T, constructed substantially as
illustrated and for purpose described.
In witness whereof, I, the said Reuben Calvert Stephenson, have hereunto
set my hand and seal, this Seventeenth day of June, in the year of our
Lord One thousand eight hundred and seventy nine.
