THOMAS BROOKS 77 Stamford Road Waterhead Oldham Cotton Carder ISAAC
JINKINSON, 150 Egerton Street Oldham Lapping Machine Overlooker do hereby
declare the nature of this invention to be as follows:-
The automatic tention motion is attached to the regulating motion of the cotton
laping machine, the regulator is supposed to regulate a given weight of cotton to a
given length of lap, the regulator is worked by means of two small cone pulleys &
a narrow belt.
Our motion is a roller constructed to revolve loose on a spindle set in two slide
brackets & pressed to the belt by means of two rods & a stay & chain over a
pulley, with a weight to keep the belt sufficiently tight to keep the regulator in full
motion.

COMPLETE SPECIFICATION.
Improvements relating to Preparing Machinery for Cotton and
other Fibres.
We,
THOMAS BROOKS, of 77, Stamford Road, Waterhead, Cotton-carder, and
ISAAC JINKINSON, of 150, Egerton Street, Lapping-machine Overlooker, both of
Oldham, in the County of Lancaster, 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 for its object to provide means for automatically retaining at
the required tension the cone strap of the feed regulating motion of cotton lapping
machines, which motion regulates a given weight of cotton to a given weight
of lap.
And in order that our invention may be more fully understood we have caused to
be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is a front view, and Fig. 2 a plan partly in section of our improved
strap tensioning motion as applied to the cones of a lapping machine positioned
horizontally.
Figs. 3, 4 & 5 are detached views of three modifications thereof.
In carrying out our invention and referring to Figs. 1 & 2, the improvements
consist in adapting a roller a to revolve loosely upon a spindle b set in two slide
brackets e fixed to the ends of the cone frame d. The said roller is pressed against
the belt e of the cones d' by two rods f secured to collars g upon the spindle and
suitably guided in the frame d. The rods are connected together by means of a
stay h having attached a chain i or its equivalent riding over a pulley mounted in
a suitable bearing k. The free end of the chain i is furnished with a weight / which
draws the roller a laterally against the belt e and retains it at the required tension
to insure the cones d¹ rotating at a uniform speed.

page_text: In lieu of employing the roller a outside the belt e it may be employed to act
against the inside of the same, as shown in Fig. 3, or two rollers a may be employed
on a swivel c¹ to act simultaneously against both sides of the belt e, as shown in
Fig. 4, the arrangement shown in Figs. 1 & 2, being however considered preferable.
Another method of tensioning the belt e laterally consists in employing the
roller a upon a weighted lever, see Fig. 5, to act either upon the inside or outside
of the belt e.
It will be readily understood that the belt tensioning motion may be also applied
in lapping machines to vertical cones.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is-
"In machinery for preparing cotton and other fibres."
1st. A cone belt tensioning device constructed and operating substantially as
and for the purpose set forth.
2nd. A cone belt tensioning device consisting of a roller or rollers a suitably
mounted and adapted to act laterally against the cone belt e, substantially as and
for the purpose set forth.
