Improvements in Drawing on Rollers Suitable Tor Combing
Machines and the like.
I, PATRICK KELLY, of Sutton Mill, Cross Hills, in the County of York, Combing
Overlooker, 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 relates to certain improvements in drawing off rollers, and has for
its object, the provision of means whereby rollers may be adjusted in elevation; so
that more length of the roller surfaces may be utilized for drawing the fibre from the
comb circles, thereby increasing the durability of the rollers; also to construct the
same in such a manner that, they rotate with less vibration, with a more positive nip,
and less pressure on the rollers than when they are constructed in the usual manner;
and consists in mounting one of the roller spindles in a socket, and securing on the
said spindle a dished flange for supporting the other roller; and the cutting of each
roller with helixial grooves and teeth, one roller being cut with right hand grooves
and teeth, the other with left hand grooves and teeth; the two being geared together
and mounted in suitable bearings.
In describing my invention more in detail, reference is made to the accompanying
sheet of drawings; in which Fig. 1 represents a portion of the plan of a comb circle
with the rollers in position; Fig. 2 an elevation of the rollers, a portion of the
mountings being in section.
The roller journal brackets A, A, are of the ordinary construction and mounted in
the usual position; the additional socket B projects through the ordinary bed plate P,
on the underside of which is secured to the said socket, a spur driving wheel C.
Through the socket B, is bored a hole for the reception of a roller spindle D, which
is secured therein by a set screw or other convenient means; the said spindle extending
through, and is supported by, the roller journal brackets A, A.
The spindle D of the other roller is made shorter, and carried by a dished flange E,
secured on the roller spindle D, the upper portion of the spindle being supported by
the before named brackets.

page_text: The teeth and grooves in each roller R, are cut helixial, one being cut to the right
hand, and the other to the left; at such an angle that, on the two rollers gearing
together, there is always some portion of the extreme diameter of the teeth of one
roller in gear with the opposite roller, thus preventing the two rollers repeatedly
moving a little towards and from each other, as is the case with each tooth on
entering and leaving the grooves of the opposite roller, when the teeth are cut in a
line with the axis of the rollers.
By my improved method of cutting the grooves and teeth, a positive nip is obtained,
thereby requiring less pressure on the rollers and leather; there being always some
of the points of the teeth in contact, thus keeping the centres of the rollers the same
distance apart and preventing or greatly miniumising what is known as "slipping,"
that is, not an uniform drag on the fibre, whereby it. is. broken and otherwise
damaged.
By securing one of the roller spindles in a socket B. I am enabled to use rollers R
of less diameter than hitherio, and still keep up the necessary firmness or rigidity at
the bottom for supporting the gearing C; the said socket also enabling me to elevate
or lower the position of the rollers, so that a longer distance of the grooved face is
available for drawing the fibre from the comb; thereby obtaining increased wear
from the rollers. The spindle D1 resting in the cup of adjustable dished flange E by
which it is carried, may also be regulated in elevation independently of the other
roller, the top end being covered by an adjustable cap F, by which the roller is pre-
vented from rising in the journals.-
The foregoing description relates to combing machines, but it will be easily
understood by persons conversant with preparing machines, and gill boxes, or other
machines requiring ground feed rollers, that the said rollers may be made with
teeth and grooves cut in the manner hereinbefore described, and obtain the same
advantages of easy and smooth running as are derived when applied to combing
machines.
Having now particularly described and ascertained the nature of this inven
tion, and in what manner the same is to be performed, I declare that.what I
claim is
1. Rollers cut with teeth and grooves in a helixical direction in a manner so that
the two rollers will gear and revolve together, in the manner and for the purpose
described..
2. The combination of the socket B, roller spindle D, and flanged dish E, with the
roller spindle D', substantially in the manner, and for the purpose described.
