PROVISIONAL SPECIFICATION.
Improvements relating to the Presser Rollers of Combing
Machines, Gill and Drawing Boxes, Wool Washing and
other like Machines.
We JOHN HENRY WHITEHEAD of the Firm Taylor Wordsworth & Co. of
Midland Junction Foundry Leeds in the County of York Machine Makers,
and WILLIAM EDWARD LAYLAND of Midland Junction Foundry aforesaid,
Mechanical Draughtsman do hereby declare the nature of this invention to be as
follows:-
This invention relates to apparatus specially designed for application to the
nip and drawing off rollers of fibre combing machines, rollers of gill and drawing
boxes, wool washing and other like machines.
According to this our said invention the necks, brasses and spiral pressure
springs are enclosed in an oblong strap or "fixings" as usual. From preferably
the lower part of the bracket for carrying the rollers extends an upright bracket,
through the outer and upper end of which is passed a bolt or stud, the latter serves
as a fulcrum for a lever the ends of which are opposite the top and bottom fixings
and through the outer ends of each of the latter is an adjusting screw having
a squared portion for application of a key. One end of each of the adjusting
screws bears upon its nut for putting pressure on the spiral springs the other
ends of the squared screws bear against the ends of the fulcrumn lever referred
to so that as the screws or either of them is turned in one or the other direction
so will it act on the nut and on the lever, and as the latter is forced outwards
the pressure
is evenly distributed by the lever to the top and bottom springs
and bushes of the rollers.

Improvements relating to the Presser Rollers of Combing
Machines, Gill and Drawing Boxes, Wool Washing and
other like Machines.
We, JOHN HENRY WHITEHEAD, of the Firm Taylor Wordsworth and Co. of
Midland Junction Foundry, Leeds, in the County of York, Machine Makers,
and WILLIAM EDWARD LAYLAND, of Midland Junction Foundry aforesaid,
Mechanical Draughtsman, 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 improvements in apparatus designed for application to
the nip and drawing off rollers of fibre combing machines, rollers of gill and drawing
boxes, wool wasbing machines, and to the rollers of domestic wringing and

page_text: mangling machines, the object of the invention being to' balance for ensure an equal
amount of pressure on each end of the roller or rollers to which the apparatus is
applied.
Such being the nature and object of our said invention, the following is a
complete description of same, référence' being had to the accompanying drawings
in which :-
Fig. is a side elevation, partly in section, of one form of our apparatus as
applied to the drawing off rollers of a combing machine.
Fig. 2 is a plan view of same.
According to this invention, the necks 1; 1 and brasses 2, 2ª of the fixed and
moveable rollers 6, 6ª are carried in oblong straps or brackets 4, spiral springs 3
being employed to support the moveable brasses 2, 2" of the moveable rollers 6 as
usual.
Secured to the projection 5 of the straps or brackets 4 either by casting
therewith, or by a screw 5*, is an arm 7' in the 'end 8 of which is a bolt or stud 9,
on which is pivoted a lever '10, the outer ends of which are opposite the top and
bottom straps or brackets 4.
Projecting from the ends of the latter are adjusting" screws 11 having squared
heads 12 for the application of a key. These screws pass through clear holes in
the straps, and have on their ends nuts 13, which slide in the cut away portions of
the straps, the nuts being grooved on the sides, so as to be guided thereby. These
nuts 13 bear on the spiral springs 3, the ends of the screws 11 passing into the
springs and acting as guides therefor. The squared' heads 12 (which may have
pointed extremities as shewn) bear against the ends of the lever 10, so that as the
Screws '11; or either of them, is turned in one or the other 'direction, so will 'they
"act on the 'nuts 13, and 'on' the lever 10;'öne end of the latter being caused to move
inward by an 'butward' movement of the other end, so that the pressure is equalized
and evenly distributed' on 'both' springs 3'and 'on' the brasses 2ª of the moveable
roller 6. Locking pins may be employed for preventing the screws 11 from
moving, such pins being dropped 'at one end into holes in the heads 12, while the
other ends engage 'in' the cut away portion of the straps 4.
"
Having now particularly described and, ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
(1.) In combination, a pair of rollers, one of which is moveable, springs for
supporting the ends of the moveable roller, the straps 4, adjusting screws 11 having
heads 12 and huts 13, the latter moveable in the straps and bearing on the springs,
ad arm 8'secured to the straps, a 'lever '10 pivoted to the said arm, the free ends of
said lever bearing on the heads of the screws to balance the pressure on the springs
and moveable roller through the nuts 13 substantially as described.
(2.) In combination, a pair of rollers, one of which is moveable, springs 3 for
supporting the ends of said rollers, adjusting screws 11 and nuts 13, the latter
bearing on the springs, a pivoted lever 10, the free ends of which bears upon the
:heads of the adjusting screws to balance the pressure on said, springs, and straps or
brackets for carrying the springs, screws, and nuts, substantially as and for the
purpose set forth.
