PROVISIONAL SPECIFICATION.
Improved Stop-motion for Combing Machines Used in the Treatment
of Fibrous Substances.
I, JONAS DENBY of 8 Arthur Street, Park Road Bingley in the County of
York, Foreman, do hereby declare the nature of this invention to be as follows,
that is to say :-
It has for its object the production of stop-motion mechanism for use in
connection with combing machines of the class known as "Nobles combs" whereby,
on the sliver failing, as by breakage or otherwise the motion of said combs is
automatically arrested, on which certain of the parts of my said improved
mechanism assume such positions as to leave all entirely clear for the operative to
repair the breach or otherwise put the fibres in order, while further when the
machine is again put into motion or started, my said stop-motion mechanism is
again adjusted automatically, or made ready for detecting any subsequent failing
of the sliver as before, without requiring the operative to rearrange or readjust any
of its several parts in any way.
To attain this object I make use of a lever arranged to be held against the pull.
or tension of a spring by a catch piece formed on another lever mounted to be in
contact with it. The said first mentioned or primary lever on being released by
the moving of the supplementary or secondary lever, is pulled or forced by its
spring to come into contact with a projecting piece secured to the rod, lever or
other part usually employed for moving or shifting the driving belt from the fast.
to the loose pulley thus in this manner arresting the motion of the machine.
When the machine is in motion or operation the secondary lever is held by a
pivoted holding catch so that it will retain by its catch piece the primary lever
against the pull of the spring as above described, while suitable connecting rods.
and other parts (as supplementary levers) are held by detector levers resting on
the sliver, from contact with and from moving or forcing said holding catch out of
its said position. However when one or other of said sliver fails then its.
respective detector levers, that was in contact with it descends by gravity and
forces the holding catch from contact with the secondary lever, thus the power of
the spring pulls the primary lever over the obstacle of the catch-piece on the
secondary lever, and thereby arrests the motion of the machine, while when and as
the said primary lever is thus moving to stop the machine, its said motion is
transmitted by cam, crank, lever or other mechanism to the secondary lever in this
manner giving it an extra movement to bring the detector lever into a raised
position entirely clear of and above the path in which the slivers travel, so that
perfect freedom is afforded for the operative to repair the failing or deficient part.
On the operative rotating the machine, the projecting piece on the sliding bar or
lever above referred to, is brought into contact with the primary lever which it
moves against the tension of the spring until the catch piece on the secondary
lever falls into position for holding it, at which time also the holding catch
assumes its effective position and the detector levers descend to rest upon the
slivers as desired and all the parts are readjusted to perform the functions desired
of them.
When the parts forming my improved mechanism are in their respective
positions last before described, the belt shifting mechanism may be freely moved

Improved Stop-motion for Combing Machines Used in the Treatment
of Fibrous Substances.
I, JONAS DENBY of 8 Arthur Street, Park Road, Bingley in the County of 1
York, Foreman, 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 :-
It has for its object the production of stop-motion mechanism for use in
connection with combing machines of the class known as "Nobles combs," whereby, 1
on the sliver failing, as by breakage or otherwise the motion of said combs is
automatically arrested, on which certain of the parts of my said improved
mechanism assume such positions as to leave all entirely clear for the operative to
repair the breach or otherwise put the fibres in order, while further when the
machine is again put into motion or started, my said stop-motion mechanism is 2
again adjusted automatically or made ready for detecting any subsequent failing of
the sliver as before, without requiring the operative to rearrange or re-adjust any
of its several parts in any way.
In order that my said invention may be readily understood and carried into
effect I have hereunto appended sheets of drawings illustrative thereof to which
by figures and letters of reference is made in the following description :-

said Fig. 5) and are illustrative of an alternative arrangement of parts to that
illustrated by the several figures hereinbefore referred to.

Fig. 12 is a view of the parts shown by Fig. 11 as seen from above.
Fig. 13 is a drawing in detail of a part hereinafter described.
Similar letters and figures of reference indicate similar parts throughout the
several views.
To attain the object of my invention I make use of a lever a arranged to be held
against the pull or tension of a spring b by a catch piece c¹ formed on another
lever c mounted to be in contact with it.
The lever a on being released by the moving of the lever c, is pulled or forced

page_text: by its spring b to come into contact with a projecting piece d' fixed on the rod d
which is used for shifting the driving belt at such time from the fast pulley e to
the loose pulley el by means of the belt guide d, thus the motion of the machine,
which is transmitted thereto through the shaft ƒ in the well known manner, is
arrested.
a
When the machine is in motion or operation the several parts are in their
respective positions shown by Figs. 1 to 6 inclusive. The lever c is held by
pivotted holding catch 9 so that it will retain the lever a by its catch piece el being
held in the path of motion of same, and that against the pull of the spring bas
above described, while suitable connecting rods h¹ (and the supplementary lever k
when this is desired to be used, as shown by Figs. 3, 4, 5, 7 and 8, or if not used
then said rodз h h are formed and arranged as shown by Figs. 9, 10, 11 and 12)
are held; by detector levers m m¹ resting on the slivers n n', from pulling or
pressing said holding catch g from contact with the lever c (in the arrangement
shown by Figs. 3 to-8 such actions are produced by the weight of the levers m m³
drawing these rods in a downward direction so that by their nuts h² h³ they
may act upon the lever k by which means they may raise or tend to raise its arm k¹
which passes beneath the arm g' of the holding catch g; and in the arrangement
shown by Figs. 9 to 12 the weight of the levers m m' effect similar results on the
catch g by forcing the rods in an upward direction so that by the nuts h² h³,
which are in this case beneath the arm g', this army' may be raised) so that all the
parts are held against the pull of said spring b.
However, when one or other of the said slivers n or n¹ fails then its respective
detector lever m or m³ descends by gravity and forces the catch g from contact
with the lever c, thus the spring b is permitted to pull the lever a over the somewhat
inclined catch piece c¹ and so bring along with the rod d by reason of coming into
contact with its projecting part d¹ and in this manner move the driving belt by the
fork or guide d from the fast pulley e to the loose pulley e¹ thus arresting the
motion of the machine, while when and as the said lever a is thus being moved by
its spring to stop the machine its said motion is employed for effecting a reverse
or upward movement of the levers m m¹ so that these may be raised to be entirely
clear of and above the path in which the slivers n n¹ travel so that perfect freedom
is afforded for the operative to repair the failing or deficient part.
The utilizing of this continued movement of the lever a for effecting said object,
I am well aware may be carried out in varied ways by using well known
mechanical equivalents for those parts that I hereinafter describe, still however as
the following devices answer their purposes efficiently the description of more
complicated arrangements is unnecessary.
In accordance with one of these arrangements I make the catch piece c¹ to act as
an incline so that as the lever a continues to move under it, it causes the lever c to
rise as shown by Figs. 7 and 8 sufficiently to bring its projection c² into contact
with the leverk lifting this latter to bring with it the rods h h¹ (by coming into
contact with the nuts 23 above it) and consequently also the levers m m' into the
position shown by Fig. 8 in which they are entirely clear of the slivers n n' as
desired.
this
On the operative having repaired the wanting or damaged sliver, by re-starting
the machine in the usual manner, which is moving the rod d, through the medium.
of the handle d, in the opposite direction to that which the spring had drawn it,
the piece d' will come into contact with the lever a, forcing it back against the
pull of the spring b until it is clear of the incline holding catch c' on which the
lever is permitted to descend by gravity and as it then is clear of the catch
latter descends by the actions of its weighted arm gl so that it again lays hold of
said lever c. During the descending of the lever into this position its projection c
will descend from holding the lever k consequently this lever k as also the rods hh
and therefore the levers m m' will descend into their normal operating positions, in
contact with the slivers where they will remain until another stoppage is effected
by the tailing of the said slivers.

page_text: The operating of the rod d by the handle d' after the parts forming the stop-
motion mechanism are readjusted as above described, does not interfere with said
mechanism or move any part of it in anyway.
C
In accordance with my other arrangement I do not utilize the lever c for causing
the levers m m' to return to their elevated position, but instead of this I mount the
lever p upon any suitable bearings so that its weighted arm when free may rest
upon the arm g' of the holding catch g and cause it by its said weight to descend
and press the rods (through the medium of the nuts 2³ beneath the arm g¹)
to raise the levers m m' as shown by Fig. 10. The liberating of the lever p to
enable it to act in this manner, is effected by the moving of the rod d, to bring its
and such
projections clear of the upwardly extending arm of the sail lever P
movement of the rod d is in the direction for bringing the belt guide d² to carry
the belt from the fast to the loose pulley to stop the machine's motion, on the
spring being liberated to act by the breakage or failing of the sliver as above
b
described.
It will be seen that instead of using the incline e in combination with the lever c
in the arrangement first before described I may employ a lever similar to the
lever p by arranging it to be operated by the lever a or again this incline c¹ may
be used instead of the lever p in the device last before described, in which case it
would be secured to the rod d instead of the projections being fixed thereon.
was
By arranging the rods hh' so that they may be guided by slotted hearings
shown by Figs. 5 and 8 1 am enabled at any time to raise the levers m m out of
their operating positions and clear of the slivers as shown in broken lines Fig. 8, or
the same result may be obtained by having the rods h¹ slotted at their lower ends
as shown at t Figs. 9 and 10.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I déclare that what I
claim is:
1. In stop-motion mechanism for combing machines, the several parts constructed
and arranged in combination as herein described for the purpose of operating and
effecting the readjustment of the detector levers by the belt shifting mechanism
substantially as specified.
2. In stop-motion mechanism for combing machines, detector-levers arranged to
put the belt shifting mechanism into action for arresting the motion of said combing
machines in combination with means whereby the said action of the belt shifting
mechanism may be employed for readjusting the said detector levers substantially
as herein specified.
3. In stop-motion mechanism for combing machines, detector-levers mounted in
bearings and otherwise constructed and arranged so that they may either be
employed for effecting the stoppage of said machines or so that without being
detached therefrom, they may be moved out of their operating positions and
thereby at such times be rendered inoperative substantially as herein set forth and
described.
4. In mechanism of the class described, detector levers pivotted on suitable
bearings, connecting rods in contact with said levers, levers and other parts
whereby one or other of said rods may be enabled to release a spring held in a
state of tension, said spring, levers and parts whereby said spring may effect the
movement of the belt shifting mechanism, and lever and incline mechanism whereby
said belt shifting mechanism may be enabled to readjust said detector levers
substantially as specified.
