Improvements in Drawing, Roving, and like Frames.
I, GUSTAVE EMILE BRULÉ, of Tourcoing, in the Republic of France, Spinner,
do hereby declare the nature of this invention to be particularly described and
ascertained in and by the following statement:—
This invention for improvements in drawing, roving and like frames relates to
apparatus for imparting the twist to the roving and involves the complete omis-
sion of the rota-rubbers hitherto employed and has for its object to effect a great
economy in driving power, estimated at a minimum of sixty per cent. per frame,
to adapt the frame for working with all kinds of wool indifferently and very
advantageously with wools of bad quality, obtaining by this system more regular
and better made roving for subsequently producing thread with, to increase the
speed of the drawing frame without inconvenience to the meshes or ribbons,"
consequently greater production by the frame and reduction of the hand-work
to a considerable extent; and to prevent the accidents caused daily by the use of
rota-rubbers; as a number of gearings are got rid of as well as many parts con-
nected with the working of these rubbers, the cost of the machine is reduced
considerably in consequence.
In the accompanying drawings Fig. 1 is an end elevation of apparatus con-
structed according to this invention. Fig. 2 is a sectional elevation taken at A-B
Fig. 1. Fig. 3 is a side elevation of the apparatus. Fig. 4 is
through CD Fig. 3, and Fig. 5 is a detail view.
a section
A Bent lever A is oscillated about a pin a by means of a connecting rod B,
which is connected by a pin b with a gearing C the rotary action of which is
effected by the bevel wheel and pinions D, E, F, the shaft I and the driving
pulley H.
A small cable fixed on a projection of a pin J, runs over a tension rod K,
fixed to an arm of the bent lever A, thence over part of a grooved pulley L
running down over another grooved pulley M, up again over a second and upper
pulley N, placed on the same axis as L, then running down and being fixed at O
to the second arm of the bent lever A.
An examination of Fig. 1 comprising the parts described above, will show that
the rotary motion of the gearing C, gives rise to an oscillating motion of the bent
lever A and alternate oscillation and rotation of the shaft P, on which the grooved
pulley M is fixed.
This alternate rotary motion of the shaft P is then transmitted through the
medium of a grooved pulley S and a small cable 5 to the small grooved pulley 6
of a special funnel R, into which the twist or
"ribbon" of wool passes
before being wound on the bobbin e (see Fig. 4).
The tension of the cable d is regulated by means of the ratchet 3 attached to
the pin J, and the part 4 fixed on the lever A.
The "ribbon" of wool T issuing from the drawing rollers passes through a
tube (Fig. 4) then between two compressing rollers 1 and 2 which are not
grooved, and thence into a funnel actuated by the alternate rotary motion
described above, in order to be wound on the bobbin e (see Fig. 4).
This funnel R, shown in detail in Fig. 5 has a central gap W, in the form of a

page_text: flattened ellipse. It is as stated above actuated by an alternating rotary motion,
which it communicates to the mesh of wool passing through it, and causes a
twisting of the same at first in one direction over a certain length which is
immediately wound on 'the bobbin e, then a twisting in the inverse'direction to the
former, over a following length of mesh.
The bobbin e, thus obtained is perfectly close and composed of a regular mesh.
successively twisted in the two directions better made than those produced
hitherto in the drawing frames with rota-rubbers, and comprising moreover a
greater development of mesh in an equal volume.
The "ribbon" obtained from a drawing frame thus constituted develops perfectly
in a flattened form, in the following drawing frame-the tension imparted to it
when being unwound is sufficient to nullify the two inverse and successive twists
and to produce a regular "ribbon," the fibres of which are rendered duly parallel
and are admirably adapted for the working on the following drawing frame.
One other consequence of these improvements consists in the omission of a large
part of the tyings" occurring in connection with the old drawing frames, pro-
ducing less length of mesh in the same volume and much less waste.
The funnel R can also be applied, in connection with the drawing-rollers and
gill-box used in roving frames between the gills and the bobbin, or spool formed by
the winding of the mesh and produces a bobbin, or spool formed like that produced
by the drawing or roving frames with funnel previously described.
The central cavity of the funnel R may also be in the form of a triangle, rect-
angle, square, cross, crescent, or right angle, effecting, but less perfectly, the
twisting of the mesh in both directions as described.
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
1. The improvements indicated and described above dispensing with the rota-
rubbers, in drawing. roving and like frames and securing the numerous advantages
set forth.
2. The employment in drawing, roving and like frames of the friction funnel R
with alternating rotary and oscillating motion, with central gap in the form of a
flattened ellipse enabling wool roving to be twisted at the moment of being wound
on the bobbin e first in one direction over a length of mesh, then immediately after-
wards in the inverse direction, over a following length of mesh, the advantages of
which have been indicated and described above.
3. The employment of the funnel R with central gap, in the form of a flattened
ellipse, in connection with the drawing rollers and gill-box used in roving frames.
4. The employment in drawing, roving and like frames of a friction funnel, with
alternating rotary or oscillating motion, having a central gap of triangular, rectan-
gular, square, cross, crescent or right angle formation producing the same results as
Those previously referred to.
