PROVISIONAL SPECIFICATION.
Improvements appertaining to the Drawing-off Rollers of Combing
or like Machines.
We, JAMES RAMSDEN HOYLE, Machine Maker, and BELTON SHACKLETON,
Foreman both of Keighley in the County of York, do hereby declare the nature
of this invention to be as follows, that is to say :-
It relates to improvements appertaining to the drawing-off rollers of combing
machines and consists of forming and arranging mechanism for compressing said
drawing-off rollers together so that same may be easier of access for regulation by
the operative while the force expended in pressing them together is more evenly
distributed throughout their entire lengths by which means neither of the edges of
the drawing-off leathers is more tightly held than the other so that their durability
is greatly enhanced.
In accordance with one method of attaining the object of our invention we
mount a cross bar to extend from the roller bearances at one end to those at the
other end thereof, the extremities of this bar being arranged to press against the
spiral springs usually employed.
On the upper roller-bearance we mount a lever one arm of which reaches into
or about the central part of the bar above described while the other extends so
that screw mechanism may be fitted to operate in connection with it in order to
cause it to press its former (arm) upon the bar and so impart pressure to the roller.
By this arrangement of bar and lever mechanism the pressure on the springs is
equally divided.
Instead of the cross bar and spiral springs above described being used a flat or
laminated spring may be mounted to reach for suitable contact with each end of
the roller or parts in connection therewith and yet the lever and screw mechanism
for imparting pressure centrally thereto, may be advantageously employed.
'
By fixing an additional cross rail to the framework and mounting a screw to
operate about centrally therethrough the lever above described may be dispensed
with, however in this case the ready adjustment is frustrated.
To increase the pressure of the ordinary screw mechanism used in connection
with the lever hereinbefore first described, a cam may be attached on or formed
about the fulcrum of said lever, which in this case would be situated in proximity
with the middle part of the cross bar the said cam being instead of and acting as
one end of said bar by being arranged to operate against said cross bar.

We, JAMES RAMSDEN HOYLE, Machine Maker, and BELTON SHACKLETON,
Foreman, both of Keighley in the County of York, 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, that is to say :-

drawing-off rollers together so that same may be easier of access for regulation by
the operative while the force expended in pressing them together is more evenly

equally to both of the edges of the drawing-off leathers in this manner the '
durability of these leathers being greatly enhanced.
In the accompanying sheet of drawings
Fig. 1 is a side elevation showing the drawing-off rollers together with our
improved mechanism.
Fig. 2 is edge view of parts shown by Fig. 1.
Fig. 3 is a similar view to Fig. 1 but shows a modified form of our improved
parts.
Fig. 4 is also a similar view to Fig. 1 and is illustrative of a further modification
of our said invention.
In accordance with our invention we mount a cross bar a to extend from the
roller bearings at b to those at 6, the extremities of this bar a being arranged to
press against the spiral springs c c.
On the upper roller-bearing band by means of the bracket d we mount a lever e
the arme of which reaches into or about the central part of the bar a while the
other arm e extends so that a screw f passing through the part d' might operate
in connection with it, moving it in the direction indicated by the arrow g in order
to cause it to press its arm e¹ upon or against the bar a and so impart pressure
through the springs c c¹ to the rollers hh. By this arrangement of bar and lever
mechanism the pressure on the spring c is equal to that on the spring c'.
Instead of the bar a and spiral springs c c being used a flat or laminated
spring (see Fig. 3) may be formed to reach for suitable contact with each end
of the roller or parts m m³ in connection therewith and yet the lever e and
screw for imparting pressure centrally thereto may be advantageously employed.
By fixing an additional cross rail to the framework and mounting a screw to
operate about centrally through it the lever e above described may be dispensed
with, however in this case the ready adjustment is frustrated.
A modification of means for imparting pressure centrally to the bar a is shown
by Fig. 4. Here we employ a camp which together with the toothed pinion r, to
which it is attached, is mounted in bearings formed on the rail s.
In gear with
this pinion is a rack t arranged to be drawn or moved by the nut u to rotate the
camp in order to increase or decrease the pressure of the bar a upon the
springs c c as and when desired.
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. The arrangement and combination of lever and screw mechanism for forcing
or pressing the rollers of combing and like machines together substantially as
herein set forth and described.
2. The combination of the bar a with the lever e, the screw f and means for
supporting same substantially as herein specified.
3. The combination of cross bar and cam mechanism for operating same so as
to press the rollers of a combing or like machine together substantially as
described.
