GEORGE LIPTROT, 199, Market Street, Whitworth, near Rochdale, Lancashire,
Card Master, FRANK SHORE, 5, Victoria Street, Whitworth, near Rochdale,
Lancashire, Engineer, do hereby declare the nature of this invention to be as
follows:
Our invention consists in arranging the slivers, say for example for a two
boss roller, so that the slivers are traversed equally to and from the weighted
point, thereby keeping the rollers always in balance.
Our invention is to have one bar or rod with a rack or racks attached to it,
also a rack or racks placed alongside the bar or rod, with a spur wheel between
the racks and in gear with same.
The sliver guides are by our invention fixed alternately on the rod and on
the rack or racks alongside of rod. The rod is worked by any suitable mech-
anism, the rack on the rod transmitting an opposite motion through the spur
wheel to the rack or racks alongside of rod, thereby traversing the slivers
along the rollers, so that they are always equally distant from the weighted
point of rollers. By this means the rollers are always equally balanced thus
being a prevention of the grooving of the rollers.

Improved Traverse Motion for Preventing the Grooving of the Rollers
of Drawing, Slubbing, Intermediate, Roving, and like Frames.
We, GEORGE LIPTROT, of 199, Market Street, Whitworth, Rochdale, in the
County of Lancaster, Card Master, and FRANK SHORE, of 23, South Street,
Rochdale aforesaid, Draughtsman, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly des
cribed and ascertained in and by the following statement:
This invention relates to improvements in the traverse motions of machinery
for preparing and spinning fibrous materials and more especially to motions of
the character referred to for drawing slubbing intermediate and roving frames

page_text: used in the preparation of cotton fibres for spinning the object being to provide
a simply operated motion the use of which will prevent the leather coverings of
the rollers used in such machines becoming grooved or worn unequally as is at
present the case.
Our invention consists essentially in a traverse motion having two rods one
of which is directly operated whilst the other is worked from the first rod through
the medium of a spur pinion, the latter engaging with rack teeth formed on
either rod.
The invention will be fully described with reference to the accompanying
drawings which show one way in which our invention may be carried out and
in which,

ments applied.

In these drawings a are the ordinary rollers through which the slubbings
or rovings pass to be drawn or elongated and b and c are the two traverse rods
which may be fitted with any suitable kind of guides to conduct the slivers
Instead
from the rollers immediately above the sliver cans to the rollers a.
of operating these two rods direct as has hitherto been the case, we fit to the
end of one of them a pair of arms or a bracket & between which a cam e can
freely work. This cam is carried on a shaft operated by any suitable means
from a convenient moving part of the machine to which the traverse motion is
applied. The revolution of the cam causes the first traverse rod b to have a
longitudinal backward and forward movement to traverse the slivers the full
width of the rollers whether such

to the second rod c of the
the rods we mount
cach rod b and c with rack teeth f and between
on a stationary stud a spur pinion g which engages with the rack teeth before
referred to. This pinion may be placed at any convenient point in the length
of the traverse rod and in order that such rods may work as close together as
possible we crank one of the rods for a short distance somewhat equivalent
to the necessary amount of total traverse required. We preferably crank the
rearmost rod c so as to enable both rods to be placed as near as possible to the
drawing rollers. By this arrangement it will be seen that the motion of the
first rod is very readily transmitted to the second rod through the agency of
the pinion referred to. We would have it understood however that whilst we
prefer the arrangement shown which is the simplest method of applying our
invention we may employ a number of short racks carrying guides to take
the place of the second rod a suitable number of pinions being also used through
which the motion is transmitted to the racks from the first traverse rod.
two rods or racks as the case may be, may be supported in suitable guides fixed
to the roller beam of the machine or may be carried by the roller stands or
in any other convenient way. The motion is very effective and may be used
on any of the machines to which traverse motions are usually applied.
The
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed we would have it under-
stood that we do not claim broadly the use of two traverse rods as such have
been in use at a date prior to our invention hereof but on the other hand what
we do claim is:-
1. In a traverse motion for drawing, slubbing, roving, and intermediate
frames the use of two rods, one of which is directly operated by a cam or
equivalent device whilst the other receives its motion from the agency of the
first by means of a pinion engaging with racks formed on both rods substan-
tially as described.
