1 claim. (ol. 1er-162)
This invention relates to an improved lap stick
adapted for use in a lapper picker, intermediate
picker, one process picker, carding machine, and
in fact in any machine where va lap roll is formed
or used in ñbre preparation.
"
Y -
A lap roll in a lapper picker is usually formed
on a hollow lap pin. When the lap is placed in
other fibre preparation machinery such as inter
I mediate pickers, or carding machines for exam
ple, the lap pin is removed but a lap stick re
mains in the lap roll for‘facilitating the handling
of the lap roll, as in processing the same in sub»
sequent machines, the lap stick serves as a stay
or a guide for the lap roll and ‘in machines such
as intermediate pickers and' carding machine the
lap stick ‘engages a suitable guide or standard
to prevent bodily movement of the lap roll vas the
lap is drawn therefrom.

Lap sticks heretofore have been >provided for
the insertion in the lap pins so that the lap pin
can be removed from the lap roll, leaving the lapï
stick in position. The- lap sticks in general use
heretofore, have been of the type shown in Pat
, ent No. 355,508, issued on January 4, 1887. This
25
type of lap stick has a cast'iron handle riveted
thereon and this handle Very often would break,
necessitating another handle being placed there
on. When a lap roll is removed from a picker,
for example, the lap, rolls are stood on end with
30
the head of lap pin being disposed downwardly
next to the floor or container in which the lap
' roll is placed. Very often it happens that the
cast iron head of the lap pin when placed upen
the floor with undue force, will crackand in sub
35 sequent operations this cracked cast iron handle
would become separated from the lap stick and
would cause the lap roll to creep into the process
ing machinery and sometimes results in destruc
40
Ation or serious damage to the machine for proc
essing the'iibres, such as, for example, the broken
lap stick entering the feeder or licker-in of a
card or by passing through the fluted feed rolls
of the carding machine.
I have devised a simple and yet very 'efficient
45 lap stick which remedies all of the above-named
defects of the lap stick heretofore in use. I pro
vide a one-piece lap stick formed of an iron rod
which is bendable and which iron rod has one
end thereof bent into a circular portion whose
plane is disposed at right angles to the longitudi
nal center of the lap stick. This provides an in
tegral handle member of the same material as the
lap stick, which handle will not break and be
come separated from the lap stick, and'there
55 fore, provides a lap stick vhaving a much longer
life than thejold type heretofore employed and
one which makes it practically impossible for any
damage to occur to the machinery due to the
breakage ofthe lap stick.
It is therefore, an object of this invention to
I..
provide a lap stick formed of a bendable iron rod 'Y
having one end thereof bent into a circular han
dle portion disposed at right angles to the main
body of the lap stick.
'
Some of the objects of the invention having
been stated„other objects will appear as the de
scription proceeds when taken in connection with
the accompanying drawing in which:-V

lcentral portionthereof broken away;

showing my lap stickin use thereon; -
Figure 4 is a top plan view of Figure 3;
Figure 5 is a longitudinal

lap stick in position;
'
Figure 6 is a view of the right-hand end of
Figure 5 but sho-wing the'position of the lap stick
as the lap pin is being Vremoved from the lap roll.
Referring more speciiically to the drawing, the
numeral l5 indicates the lap stick proper which
is bent as at ll, at right angles and after being
bent outwardly a suitable distance is then bent
laterally and formed into a complete circle form- ¿
ing a handle member l2. The lap stick is usually
inserted in a lap pin i3 disposed with a lap Vroll
I4. ’I‘heY lap roll is formed on a picker and is
laterV employed in intermediate and finisher
pickers, such as shown by reference character I5.
In one process pickers, of course, the fibres are CO Cl
passed from the breaker to a series of pickers to
the ñnisher picker where the lap roll is formed,
but in other forms of pickers the breaker lapper
forms the lap rolls on the lap pin and then they
are transferred to the intermediate picker as
shown in Figure 3. YThis intermediate picker has
an endless chain l5 for feeding the laps` from the
lap rolls It. It will be seen in Figures 3 and 4
that the lap sticks l@ rest behind the standards
l1 and the lap stick is usually much longer than
the lap width and projects laterally from one side
andthe handle member l 2 serves as a guide with
relation to standard i 'l on one side so that creep
ing of the lap stick from the lap roll is avoided.
When the lap roll is formed on the picker and is
transferred to other machines such as another
intermediate or a. finisher picker or into a card
ing machine from the finisher picker only the
lap stick remains._ The lap pin is removed from 55

2
the lap roll as shown in Figure 6, leaving the lap
stick to serve as the guiding means and handling
means for the lap roll.
It is seen that in any of the above-described
machinery that should the handle portion become
separated this would allow a creeping away from
the observer in Figures 3 and 4 and would allow
the lap roll along with the broken lap stick to be
carried forward into the beater 20 of the inter
mediate picker in Figures 3 and 4, doing serious
damage if not irreparable injury to the beater.
The same damage might occur in a carding ma
chine as previously explained.
It is therefore seen that I have provided an in
tegral one-piece lap stick formed of a relatively
non-breakable material so that the probability
of breakage and resultant damage to the machine
is avoided.
'
In the drawing and speciñcation there has been
set forth a preferred embodiment of the invention
and although specific terms are employed, they Cil
are used in a generic and descriptive sense only,
and not for purposes of limitation, the scope of
the invention being set forth in the appended
claim.
I claim:
A lap stick formed from a rod or iron having
one end bent laterally at right angles to the rod
and then bent into a circular portion occupying
a plane at right angles to the longitudinal center
` of the rod.
