Improvements in Combing Machines.
We, WILLIAM WILKSON KENDALL, Overseer, and JASPER KENDALL, Carder;.
both of No. 22 Troy Street, in the City of Providence, in the County of Providence,,
and State of Rhode Island, United States of America, 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 :-
This invention has reference to an improvement in machines for combing fibrous
material, and consists in the peculiar and novel construction of the drawing-off:
rolls, as will be more fully set forth hereinafter.
In combing-machines the fibrous material is straightened and combed out on.
revolving combs and the combed-out fibre is drawn off from the combs, doubled'
and sometimes slightly twisted to form a sliver. The drawing-off of the fibre was
heretofore accomplished by the use of two corrugated rolls and an endless apron
or belt which, in passing between the corrugated rolls, was bent by the corrugation
of the outer roll into the corrugation of the roll on which the apron or belt was
carried and the fibre was gripped between the corrugated cuter roll and the apron..
In this former construction of the drawing-off rolls the apron or belt is subjected
to a continuous transverse crimping action between the two corrugated rolls, the
corrugations of which act like the intermeshing teeth of two gears, the apron or
belt was first injured as a carrier, because the transverse grooves or crimps presented*
an uneven surface or support for the fibre, and the apron or belt was soon destroyed
by the bending and grinding action of the intermeshed corrugations.
The object of this invention is to secure a better grip on the fibre in drawing'
off, to carry the fibre in a longitudinal groove, gradually flattening out to facilitate
its transfer, and to avoid the transverse crimping and wear of the apron or belt.
Figure 1 is a top view of part of a combing-machine showing the application of
my improved drawing-off rolls to the same.
Figure 2 is a side view, partly in section, showing the improved drawing-off
rolls in connection with an apron or belt.
Figure 3 is a transverse view showing the co-acting drawing-off rolls and the
apron or belt.
Similar numbers of reference indicate corresponding parts in all the figures.
In the drawings 4 designates a part of the large annular comb, 5 one of the
smaller annular combs, 6, 6, the pair of drawing-off rolls by which the fibre is
drawn off from the large annular comb 4, and 61, 6¹ the pair of drawing-off rolls
operating in connection with the smaller annular comb 5, 7 the apron or belt,.
8, 8, the guide-pulleys by which the apron or belt is carried and guided,-these
pulleys 8, 8, have cylindrical or slightly curved surfaces and are the usual pulleys
employed for carrying the belt or apron. 9, 9, are the shafts to which the drawing-off
rolls 6, 6, are secured, 10, 10, the gears secured to each one of the shafts 9, 9, by
which both shafts are geared so as to turn together, and 11 the driving-gear secured
to one of the shafts 9 through which motion is imparted to the drawing-off rolls.
To illustrate the action of these drawing-off rolls 6, 6, we have marked them in
Figures 2 and 3 as 6 and 6b; the roller 6, which carries the apron or belt 7, is.
provided on its periphery with a V-shaped groove, and the roller 6° has its
periphery formed into a V-shaped face so that it will force the apron or belt into.
the V-shaped groove of the roll 6", thus forming on the belt a groove 71 in which.

page_text: the fibre is carried. The groove 71 diminishes gradually and, when the belt reaches
the pulley 8, disappears by the belt assuming the normal flat surface, while in the
groove of the belt the fibre is held more securely than it is held on the flat surface,
and when another belt travels with the first belt, as is shown in Figure 1, the
grooved belt will readily draw the fibre off from the flat surface of the belt.
In the drawing-off the fibre is drawn in between the beveled faces of the roll 6'
and the belt 7; it is held sufficiently tight to be readily drawn off from the comb.
The longitudinal grooving affects only a small portion of the belt or apron and
is not as injurious to the belt as is the transverse crimping between the corrugated
rolls heretofore used.
We do not wish to confine ourselves to the exact form of the faces of the two
drawing-off rolls shown and described in what we now consider the preferred form.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1
1. In a machine for combing textile material, a pair of drawing-off rolls one of
which is formed with a groove extending around its periphery and the other with a
projection corresponding with the grooved roll, whereby an apron carried by the
rolls will be longitudinally bent, as described.
2. In a combing-machine, the combination with the combs and the drawing-off
apron, of two drawing-off rolls, the face of one provided with inclined projecting
annular surfaces and the face of the other with corresponding inclined retracting
annular surfaces, and an apron, whereby the apron is longitudinally bent to form a
groove and the fibre is drawn into the groove, as described.
3. In a combing-machine, the combination with the comb, the carrier-apron and
the pulley supporting the apron, of two drawing-off rolls one of which is provided
with a grooved periphery adapted to bend the belt longitudinally to form a groove,
as described.
4. In a combing-machine, the combination with the combs, of the drawing-off
rolls 6ª and 6, the pulleys 8, 8, and mechanism for operating the same, as
described.
