APPARATUS FOR TREATING YARN
Homer V. Lang, Charlotte, N. 0‘.
Application May‘3, 1937, Serial No. 140,477
8 Claims.
This invention relates to a machine for condi
tioning textile ?bres such as packages of yarn in
the form of bobbins, cops and the like. In the
textile art, thread on the bobbin is treated with
5 a solution, with certain ingredients therein, in
order to set the twist in the thread before it is
used for other purposes. In machines heretofore
used for moistening or conditioning yarn it has
been necessary to employ machinery which occu
10 pied considerable floor space so that all portions
of the packages would be subjected to this treat
ing solution. Other machines have been provided
which did not occupy a great deal of ?oor space
but yet the means for turning the packages while
15 being subjected to the treating solution entailed
mechanism which has not proven to be efficient
and practical.
It is therefore, an object of this invention to
provide an apparatus which has means for turn
20 ing the packages while the same are being sub
jected to a spray of the treating solution so that
all portions thereof may be equally treated. This
turning means comprises a pair of beveled baf
fies or guards which are oppositely disposed above
25 a conveyor belt and in the path of travel of the
packages. As the conveyor passes beneath these
guards or ba?les the packages contact these guards
and are caused to creep laterally of the conveyor
(Cl. 68-—205)
It is a further object of this invention to pro
vide an apparatus for treating yarn comprising
a conveyor upon which the bobbins are placed for
treatment with means for rotating the conveyor
beneath a plurality of thin sheet sprays which are 5
directed downwardly upon the packages from
spaced nozzles. These nozzles are of a peculiar
design which spray the liquid therefrom in a sheet
formation so that at the point where the liquid
strikes the top of the conveyor the longest side 10
of the sheet will be disposed at right angles to
the path of travel of the conveyor. By providing
this nozzle it is evident that all of the packages
which’are disposed on the conveyor will be treat
ed with an equal amount of solution. In the con- .15
ventional nozzles the cross sectional area of the
spray at the point of contact with the conveyor
is circular in shape; consequently, when the pack
ages pass beneath this spray those packages
which traverse the central portion of this circular 20
spray will be subjected to more liquid than those
which traverse the outer edge portions of the
spray. 'I have arranged a plurality of my in
proved nozzles in alinement directly above the
conveyor belt so that as many of the same may 25
be used as desired to vary the quantity of solu
tion which is sprayed upon the packages as they
pass beneath the spray nozzles.
Some of the objects of the invention having
been stated, other objects will appear in the de
scription hereinafter following, when taken in
connection with the accompanying drawings, in
cause the bobbins thereon to be rotated so as to which:

Referring more speci?cally to the drawings, the
numeral l9 denotes the back end frame support
which has resting on the upper portion thereof
baffles 4'! and 48 are placed in a staggered relation
to each other so that all of the bobbins will be al

the front end of said angle members being secured
to the upper portion of inclined angle supports
!3 and I4 respectively. Secured to the inclined
10 members I3 and I4 and near the lowermost por
tion thereof are angle struts 15 which project
rearwardly of the machine and are secured to
the lowermost portion of 7 support It).
Also se
cured to- the lowermost portion of inclined mem
15 bers l3 and I4 are shoes l6, said shoes having solts
l8 therein into» which bearings 19 are adapted
to slide. These bearings house the ends of shaft
20 upon which sprockets 2| are ?xedly secured.
The positions of bearings l9 are adjusted by
20 means of set screws 22 which are threadably se
cured in outstanding lugs 22a in the upper end
of brackets 16 with the lower ends of said screws
contacting the upper‘ side of the bearings l9.
Suitable sprocket chains 24 are adapted to be
25 mounted upon the sprockets 2| and 2B, and upon
these sprocket chains cross bars 25 and 25a. are
secured for supporting bobbins 26 and conveying
them to the position where they are to be treated.
The conveyor is broadly indicated by reference
30 character 21. The cross pieces 25a are higher
than the pieces 25 so that a predetermined
amount ofpackages will be collected and con
veyed upwardly. The sprockets 28 are ?xedly
secured on cross shaft 29, said shaft having its
35 ends rotatably mounted in the inclined members
l3 and I4. These inclined members l3 and 14
are spaced apart from each other by means of
struts 39.
‘
In order to provide means for holding a supply
4.0 of'bobbins or packages 26, a suitable hopper 3!‘
has been mounted upon the top of inclined mem
bers l3 and H!‘ with its sides surrounding the top
side of the conveyor. When the bobbins are
placed in the hopper 3| as shown in Figure
45 5, the high cross pieces 25a will collect a portion
thereof and convey them towards the top of the
conveyor where they will be delivered-to a hori
zontally disposed conveyor 33.
This conveyor comprises a plurality of horizon
tally
disposed rods 34 which are secured between‘
50
sprocket chains 35. These chains, in turn, are
rotatably mounted upon sprockets 31 and 38
which are ?xedly secured upon shafts 39 and 40
respectively.
posite direction until they have passed out from
beneath the spray. This creeping or shuffling of
the bobbins causes all portions thereof to be
10
turned and exposed to the spray.
The conveyor belt 33 is held in taut position
by means of the bearings 50 whichare secured
to the outside of angle members II and I2. The
ends of the shaft 49 are rotatably mounted in
blocks 5! which blocks are slidably mounted in 15
slots 5lla.in these bearings. Set screws 52 nor
Vmally contact these blocks to hold the shaft 49
in the desired position so that the belt will re
main taut.
In order to provide means for driving the con 20
veyor belts 2‘! and 33, a suitable motor 55 has
been mounted upon bracket 56 which extends out
from the framework of the apparatus.
This mo
tor has a motor shaft 51 and a pulley 58 upon
which a. belt 59 is mounted.
This belt is also 25
mounted upon a larger pulley 5|! which is secured
to the end of a shaft 6!. The shaft 6| is rotat~
ably mounted in inclined angle members i3 and
I4 and has secured on the other end thereof a
pinion 62 which meshes with a larger gear 63, 30
said gear 63 being ?xedly secured on shaft 29.
Upon rotation of the motor shaft 51, counter
clockwise motion is imparted to the shaft 29
through the members just described, to cause the
conveyor belt 21 to deliver predetermined quan
titles of bobbins 25 to the conveyor 33.
The shaft 29 also has a sprocket 64 secured
thereon upon which is mounted a sprocket chain
65. This chain is also mounted upon a second
sprocket 65 which is ?xedly mounted upon the 40
shaft 39. The counter-clockwise motion of shaft
29 will therefore be imparted to the shaft 39
which in turn will cause the conveyor belt 33 to
transport the bobbins toward the rear of the
machine.

Secured between the upper sidewall portions
46 and 45 is a pair of rods 19 upon which is se
cured a bracket ‘II which supports a T-shaped
pipe ?tting 12, into which liquid is delivered from
hose 13. Leading from opposed ends of member 50
12 are suitable short. pipes 15 which have the
other ends thereof connected to through valves
16. (Figures 5 and 6.)
Nozzles 11 are connected
The ends of the shafts 39 and 49 . to the lower portion of the valves 16 and these
55 are rotatably mounted‘ in suitable bearings se~
cured to the horizontal angle members I l and [2,
The sides of the conveyor 33 are enclosed by
side walls 45 and 46 mounted upon the angle
members II and I2 respectively. These sides
60 have beveled baf?es 41 and 48 secured thereto
with the lower end of the baffles extending over
the top of the conveyor belt 33. When the in
clined conveyor 21 delivers the packages to the
horizontal conveyor 33 as shown in Figure 3, the
65 movement of conveyor 33 will cause the bobbins
to ?rst contact the ba?ie 48. Upon further move
ment of the conveyor the bobbins will be caused
to creep and roll towards the observer in Figure
3 at the same time the spray will be projected
downwardly thereon from the nozzles. The baffle
41, which is secured on the opposed side of the
conveyor, will then be contacted by the bobbins
on this side of the conveyor thereby causing the
whole batch to creep and roll away from the ob
server in Figure 3. It will be noted that the
nozzles have an ori?ce 18 in the lower portion
thereof through which the spray is forced. (Fig
ure '7.) It will be noted that the lower portion
of the nozzles have an elongated groove 19 which
is diametrically disposed relative to the ori?ce
18. Also, on the inside of the nozzle are diamet
60
rically disposed grooves 80 which intersect the
upper portion of the ori?ce. The liquid moves
downwardly through the ori?ce ‘l8 and due to the
grooves 19 and 80 the spray is caused to assume
substantially a rectangular shape at the con 65
veyor thereby maintaining an even width of
spray across the conveyor. ‘This will insure that
all portions of the conveyor as it passes beneath
this spray will be subjected to an equal amount 70
of treating solution. As heretofore stated, if the
spray were circular in shape at the point where
it contacted the conveyor then the portions of
the conveyor which pass beneath the central por
tion of this circular area will be subjected to
75
3
2,163,046
more treating solution than those portions which
pass through the outer edges thereof.
Each of the valves ‘I6 has leading therefrom
another pipe 85 which is connected to a spray
head 86, said head being identical in all respects
to the spray head 'I'I recently described. All of
the spray heads such as 11 and 86 are placed in
alinement with each other substantially over the
center line of the conveyor so that variable quan
10 tities of liquid may be delivered to the bobbins on
the conveyor. If desired, by means of the wheels
8'! of the valves ‘I6 the ports 98 which lead to the
nozzles 11 may be closed and only the outer spray
heads 89 used.
The T-?tting ‘I2 has a gauge 99 secured thereto
15
which registers the amount of pressure set up in
spray heads and the delivery hose 13. This de
livery hose has its lower end connected to the
outlet pipe 9| of pump 92, said pump being driven
20 by the motor shaft 51 simultaneously with the
driving of the conveyors. The pump has an inlet
pipe 93 leading thereto, to which is secured a
hose 94. This hose leads to the lower portion of
container‘ 95 in which the treating solution is
25 placed. When the motor is in operation the
pump draws the solution from the container 95
through the pump 92, hose ‘I3, and forces it out
through the spray heads ‘I1 and 89 onto the bob
bins 26 which are disposed upon the conveyor 33.
30 If for any reason, it is desired to use only the
outer spray heads 86 then the ports 88 are closed.
Due to the closing of the ports 88, but at the
same time maintaining the same speed of the
motor and pumps, a pressure will naturally be
35 built up in the hose 13. In order to neutralize
this excess pressure and prevent more solution
from passing through the nozzles which are then
in use, a suitable by-pass pipe 91 has been pro
vided which has one end thereof connected to
40 the outlet pipe 9| and its other end connected to
the inlet pipe 93. Disposed in this by-pass is a
spring check valve 98 which has a ball 99 there
in‘ normally closing a port I99.
A spring I9I
normally presses the ball to a closed position,
45
(Figure 8) , but due to the adjustment of the pres
sure on spring I9I liquid will be allowed to ?ow
through the port I99 and into the intake side of
the pipe line when an excessive pressure is built
up in the hose ‘I3.
The point at which liquid will be caused to ?ow
through the port I99, is varied by means of cap
98a which is threadably secured on the end of
the check valve casing 98 to vary the amount of
pressure exerted upon the spring I 9| and ball 99.
The eXcess liquid which is sprayed upon the
55
bobbins and the conveyor is caught by a suitable
inclined pan I93 which is disposed directly be
50
neath the conveyor belt 33. This pan has an out
let I94 in the side portion thereof at a point
60 where the excess liquid will be delivered to the
opening I95 in the top of container 95. This
opening has a strainer I96 disposed therein for
removing any objectionable matter from the
liquid. Figures 9 and 10 show a slightly modi?ed
65 form of conveyor belt which may be used to re
place conveyor 33.
This conveyor comprises a
plurality of slats I98 which have raised ribs I98a
on the top surface thereof thereby forming a
dished channel I98b‘ for holding a limited supply
of the treating fluid from the nozzles. The pack
ages of yarn which rest upon these slats will ab
sorb the treating ?uid in these channels. These
slats are secured to suitable links I99 of a
sprocket chain in the manner shown in Figure 9.
In the drawings and speci?cation there has
been set forth a preferred embodiment of the
invention, and although speci?c terms are em
ployed, they 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 claims.
