PROVISIONAL SPECIFICATION.
Improved Stop-mechanism for Gill-boxes or like Machines employed
in the Preparation of Wool or other Fibrous Substances.
:
We, JOHN SKINNER, Overlooker, and JOSEPH MITCHELL, Comb Maker, both
of Morton Banks near Keighley in the County of York, do hereby declare the
nature of this invention to be as follows, that is to say :-
It consists of improved stop-mechanism applicable for use in connection with the
feed rollers of gill-boxes or like machines employed in the preparation of wool or
other fibrous substances whereby the motions of said machines are arrested when-
ever said feed rollers are forced beyond a prearranged distance apart as by any
inequality in the thickness or quantity of wool or the like passing between them,
in this manner entirely preventing any damages to the fallers or other operating
parts caused by excessive quantities of the fibrous substances being fed thereto as
is well understood.
To attain this object we mount a lever to operate in connection with, as by one
of its ends spanning, the axial shaft of the upper or yielding feed-roller so t at as
said roller moves radially from or towards the other roller this lever is moved in
order that by a suitably formed connecting rod and coupling joint it may act upon
a catch-lever. This catch-lever reaches into connection with a sliding-block that
it holds in a normal position against the pressure of a spring so long as the
machine continues in its proper motion by its feed rollers not being forced too far
apart, however when said feed rollers are moved as above described they operate'
this catch-lever in order to release the sliding-block which is then free to be moved
by its spring, and as it is arranged to operate in proximity with the belt shifting
mechanism of the machine, by said block coming into contact with a projecting
piece mounted on the operating rod or lever of this mechanism, the belt is moved
from the fast to the loose pulley and so the motion of the machine is arrested.
After the clearing away of the fibrous substances from between the feed rollers,
the whole of the parts forming the above described mechanism are re-adjusted or
caused to assume their proper respective positions on the moving of the belt
shifting mechanism by the operative when re-starting the machine in motion.

COMPLETE SPECIFICATION.
35 Improved Stop-mechanism for Gill-boxes or like Machines employed
in the Preparation of Wool or other Fibrous Substances.
We JOHN SKINNER, Overlooker, and JOSEPH MITCHELL, Comb Maker, both
of Morton Banks, near 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
0 particularly described and ascertained in and by the following statement, that is
to say :-
.
It consists of improved stop mechanism applicable for use in connection with the
feed rollers of gill-boxes or like machines employed in the preparation of wool or
other fibrous substances whereby the motions of said machines are arrested when-
5 ever said feed rollers are forced beyond a prearranged distance apart, as by any

page_text: inequality in the thickness or quantity of wool or the like passing between them
in this manner entirely preventing any damages to the fallers or other operating
parts caused by excessive quantities of the fibrous substances being fed thereto as
is well understood.
In the accompanying sheets of drawings
Fig. 1 is sectional side elevation of a portion of a machine shewing the application
of our improved mechanism.
Fig.
is part sectional top view of said parts and mechanism, and Fig. 3 is front
view of same.
To attain the object of our invention we mount the lever a to operate in con-
nection with the axial-shaft 1 of the upper or yielding feed roller b. The fulcrum
of the lever a is at a while its extremity a² is extended and made to encircle the
shaft b'as shewn by Fig. 1, its other extremity a³ being arranged for carrying the
connecting rod c. As the roller is raised or moved radially from the roller d, by
reason of anything passing between it and said roller d, the lever a has its end a
moved in a corresponding degree, and this movement it imparts to the rod c.
с
This rod c is arranged to operate in connection with the catch-lever e by having
its outer end c¹ operating through an opening in the end of this said lever e while
an adjustable hoop f is rigidly attached to it, so that whenever the rod c is moved
in a downward direction sufficiently far to bring its hoop f into contact with
the lever e this end of the lever e will be thereby also moved in a downward
direction.
The other end e' of the catch-lever e reaches into connection with the sliding
block g (which is arranged to slide upon the fixed rod h) in such a manner as to
hold said sliding block 9 in a normal position (shewn in the drawings) against the
pressure of a spring k so long as the machine continues in its proper motion by its
rollers and d not being forced too far apart, however when said roller b is raised
beyond its usual distance from said roller d so as to bring its hoop f into contact
with and to move the lever e, then the sliding-block g is released from being held
by the arme of the lever e and so its spring k causes it to move and (by the pro-
jection g' on said block 9) bring with it the projecting finger / which is rigidly
attached to the bar m carrying the belt shifting fork n in this manner arresting
the motion of the machine by moving the driving belt from the fast to the loose
pulley.
After the clearing away of the fibrous substances from between the feed rollers
and d on the motion of the machine having being arrested by an accumulation of
such material, all the above described parts are re-adjusted or caused to assume
their proper respective positions on the bar m being drawn back by the well known
handle-mechanism as the operative restarts the machine or moves the bar m so
that the fork n brings the driving belt from the loose to the fast driving pulley.
The lever a is herein before described as being arranged to be in contact with
the roller at about its central part but it will readily be understood that we might
mount such a lever to be in contact with each of the outer ends of said roller & so
that should either of these ends alone be raised the motion of the machine would
thereby be arrested.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :
1. Lever mechanism arranged to be operated by the yielding roller of a gill-box
or like machine, so that the motion of said machine may be thereby arrested 5
substantially as herein specified.
2. Lever mechanism arranged to operate in connection with, the yielding rolle
of a gill-box or like machine, in such a manner as to release a sliding block
operated by a spring substantially as and for the purposes specified.
3. The arrangement of lever and other mechanisms in combination with the 5
rollers of a gill-box or like machine, in such a manner that their adjustment may

page_text: be regulated so as to arrest the motion of said machine when its said rollers are
moved a greater distance apart than is or may be desired substantially as specified
and for the purpose set forth.
