Improvements in Automatic Stop Mechanism for Wool Combing
Machines
I JOHN HAYMAN ROGERS of No 2,720 C Street, Philadelphia Philadelphia
County, Pennsylvania USA Foreman Wool Combing Dept hereby declare
the nature of this invention and in what manner the same is to be performed, to be
particularly de cribed and a-certained in and by the following statement
-
My invention relates to automatic stop mechanism for wool combing machines
the ame being especially applicable to those of the Noble type It is a well
known fact that in machines of this kind when the liver is drawn from the drawing
off rolls of the small circles and led thence through the trumpet, the same is apt to
break, and if, after breakage, the motion of the machine is continued, the combs of
the machine are apt to be broken, the sliver itself will lap and cause waste of
material and damage to the machire and cause loss of time in extricating the tangled
and gnailed wool from the comb and other parts of the machine My invention
is designed to overcome this by providing automatic means for shifting the belt
upon the main shaft of the machine instantaneously upon the breakage of the sliver
at any point The same consists of a plate secured to the upper part of the
machine, in which is mounted a laterally disposed rod, carrying an aim provided
with a loop at one end which surrounds the rod cairying the belt shifting device
and adapted to engage a collar on said rod A spring is employed connected to
said movable 1od at the point at which said arm is secured ind fastened at its other
end to one of the bearings of said movable rod This movable rod is adapted to be
held in its adjusted position by means of a notched fever which engages one und
thereof Pivotally mounted on said plate is a lever, one end of which is weighted
and the other end of which has connected thereto i bar, provided with a hook or
catch at its lower end lending ontwaidly and engaging projections on the ends of
two arms pivoted in a suitable standard or support These aims are extended
outwardly and beneath them pass the slivers from the two small circle-
If one or
the other of the slivers break, the arm to which it was attached will fall, thereby
releasing said weighted lever secured to the bracket, thus engaging the transversely
movable rod which in turn shifts a rod carrying the belt device thereby stopping
the machine
The invention also consists of other det uls of construction and combination of
parts which will be more fully hereinafter described and claimed
In the drawings forming a part of the Specification
Figure 1, represents a side elevation of my stop mechanism, showing the belt
shifting device of the combing machine
Figure 2, represents a imilar view of the same with the parts in the position
they assume when a sliver has been broken and the machine stopped
Figure 3, is a side elevation of the upright or standard in which the arms
supported by the slivers are pivoted
Like reference numerals indicate like parts in the various views
By reference to the drawing it will be seen that 1 represents the main shaft of
the combing machine, having thereon the fast pulley 2 nd the loose pulley 3, with
which the driving belt 4 is adapted to engage o is a plate, bolted or otherwise
secured to the framework of the upper part of the machine and 6 is a laterally
disposed rod, mounted in suitable bearings and carrying the belt shifter 7, as
clearly shown Mounted in suitable bearing, 8, 8, is a second rod 9, havin

page_text: secured thereto and adapted to move therewith an arm 10, having bifurcated ends
which surround the rod 6 and adapted to engage a fixed collar, 10, on said rod
A coiled spring 11 is secured to the rud 9 at the point of connection of the arm 10
and to one of the boxes 8, in which said 10d 9 is adapted to move Pivoted to the
plate or bracket is detent lever 13 having a tooth 14 thereon which is adapted
to engage one end of the 1od 9 when the litter in its adjusted or set position
The release of this lever 13 from engagement with the rod 9 will cause the latter
to be thrown inwardly under the influence of the coiled pring 11 The release of
this lever 13, is caused by the mechanism which will be now described
An upright or standard 15 s bolted or otherwise secured to the base or bed
plate of the combing machine and in it is secured a bar 16, formed with pro-
Jections 17 at its upper end Pivoted to these projections 17, one on each side
thereof, are two arms or levels 18, 18 having inwardly projecting lugs or fingers 20
at their inner ends Beneath the outer end of the arms 18, the slivers leiding
from the two smaller circles are passed, which are conducted thence through the
trumpet 21 of ordiniy construction and by these slivers said aims are held in their
upper positions, as clearly shown in Figure 1 Loosely attached to the fingers 20
of the ms 18 is the hooked end 22 of a rod 23 connected at its upper end to one
The other
arm of a lever 24 pivoted to the plate or bracket 5 as clearly shown
end of said level 24 is weighted, as shown at 25 and the tendency of this arm is to
drop I he other aim of sud level is idapted to engage during its upward stroke
with the free end of the lever 13 which releases the iod 9 Secured to the plate
or bracket 5, and leading downwardly therefrom and formed with loop at its
lower end is a guide od 26 for the rod 23 By this construction it will be seen
that when the lever 9 is adjusted and sut, as shown in Figure 1, the combin
machine is in operation, the driving belt 4 being in engagement with the fast
pulley 2 on the main shaft 1 The slivers from the small circles pass beneath the
outer ends of the ms 18, thence through the trumpet 21, and the rod 23 1-
attached to and held downwardly by the fingers or projections 20 on the inner ends
of the arms 18 If by chance one or both of the slivers should break one or both
of the ums 18 will drop into position shown in Figure 2 the rod 23 will be released
and the outer or weighted cnd 25 of the level 24 will fall, throwing the inner atm
upwardly and releasing the lever 13 from engagement with the inner end of the
1od 9 When this takes place the 1od 9, cariying the arm 10 will be thrown to
the left through the action of the coiled spring 11, and the am 10 engaging the
collar 10 on the shaft 6 will throw the latter in the sime direction, shifting the
belt 4 from the fast pulley 2 to the loose pulley 3, thereby stopping the operation
of the machine and preventing any breakage of the parts or loss of time
Having now particularly described and ascertained the nature of my said invcu-
tion and in what manner the same is to be performed, I declare that what I
claim 18
1 The combination with a wool combing machine, having a main shaft with fast
and loose pulleys theicon, of mechanism for automatically stopping the machine by
shifting the belt from the fast to the loo e pulley, the same consisting of a rod,
having a belt shifter secured thereto, mounted transversely of the machine, a
second rod parallel thereto cariying an arm which is adapted to engage a collar on
said belt shifting rod, a spring connected to said second rod, means for holding
said od in its adjusted oi set position and means thrown into operation by the
breakage of a sliver for releasing said rod, substantially as and for the purposes
described
2 The combination with a wool combing machine having a main shaft with fast
