Vasser Woolley, Atlanta, Ga., assignor to 'Seydel- Woolley & Company, Atlanta, Ga., a copartnership of Georgia consisting of Paul Seydel, John R. Seydei, Vasser Woolley, Mildred Seydel and Bessie R. Wooliey Application March 16, 1944, Serial No. 526,747

4 Claims. (01. ss-zos) l- V This invention relates to machines for conditioning yam while in the form of packages such as bobbins, cones, spools or cops especially for setting the twist in the yarn. This application is in part a continuation of my Patent No. 2,347,-

It has been customary to apply the liquid to such yarn while the packages, which for convenience we will call bobbins, are travelling on a conveyor belt, or chain or through a revolving cylinder. A great difliculty in all of such machines has been the excessive wear on the moving parts which operate without lubrication underthe spray of water and penetrant. In some cases steam is applied but this is injurious to the bobbins and esteem room takes up a great deal of space.

This invention is the result of extensive study of the conditions involved in this work. One ob ject is to provide a satisfactory machine for uniformly applying the proper amount of liquid without spotting or damage to the yarn.

A special object is to provide a simple and inexpensive machine in which the packages require no moving devices to carry them through.

Another object is toprovide a compact and inexpensive machine.

Accordingly the preferred form of machine embodies a casing having a vertical series of inclined bames. grids or grilles arrangediso that packages dropped on the upper baiiie, roll or spin and fall down on to a lower grille and thence fall upon a lower grille and-thence roll or spin out of the hin Sprays of the desired liquid are blown or otherwise forced from opposite sides of the machine on to the moving packages beused liquid through the grilles and back substitute .spray heads of different sizes or ad- 978, dated May 2, 1944, in which the method or process per se is claimed.

just the discharge. I may also modify the action by substituting grillw of different design or different sizes of openings or partially closing the grilles.

Fig. l'is a side view of a machine embodying one form of my invention parts being broken away and in section to show the interior with'a number of bobbins tumbling through under treatment.

Fig. 2 is a front view of the same machine.

' Fig. 3 is a vertical sectional view showing the upper work baiile and its collecting trough,

Fig. 4 is a, vertical sectional view showing a part of the lower baflie and discharge port.

The upper part 5 of the casing constitutesthe treating chamber with an inlet 6 for receiving the packages and an outlet '1 from which they are discharged. Leading inwardly from the inlet is an inclined shelf or baflle plate 8 which is prefgrille, then to the lower grille and thence down the inclined discharge chute H which is inclined at a less inclination than the grille "I so as to slow up the packages as they are discharged. The grilles have suitable openings to allow liquid to pass but prevent the packages from getting caught or passing through. The chute is prefinto the supply tank from which it is again forced from the spray heads to be used again until exhausted This used liquid is preferably filtered before passing back into the supply tank.

The various grilles are preferably made readily removable to facilitate cleaning and also to permit substitution'of different grilles. The ex-.

cess liquid which flows through the upper grille is diverted from the treating chamber so as to prevent drops of liquid fromfalling upon the bobbins traveling over the lower grille and which heads 13 or nozzles preferably adjustable so as to erably made up of a number of smooth parallel rods spaced apart so as to leave ample space for liquid to pass through but prevent the packages from falling through. I

The lower part I2 01 the casing constitutes a reservoir for holding the treating liquid or penetrant. Beneath the bafile are located two spray control the spray which is discharged. between thebame 8 and the grille 9 to envelop the packages as they fall. Beneath the grille 9 are located two more spray heads l4 preferably adjustable anddirected to envelop the packages as they fall from the upper-grille to the lower grille and roll and tumble on to the discharge chute II.

The penetrant liquid is drawn fromthe reservoir l2 and forced to the discharge spray heads by a circulating pump l5.

At the bottom of the treating chamber is a filter pad It for removing foreign particles from u the treating liquid. An additional filter 11 is mterposed between the pump and the spray heads. In addition a pressure regulator is is interposed between the filter l1 and the spray heads.

To prevent liquid from dripping from the upper grille upon the packages beneath I provide a. collecting trough or gutter I9 which discharges through a duct 20 which leads to a point beneath the chute Ii but above the filter pad I6.

Similarly a drip pan H is located beneath the lower grille iii.

Beneath this drip pan is an inlet opening 22 and a hinged baiiie 23.

At the top of the casing is an electric for illuminating the treating chamber.

The opening 22 provides access to the interior lamp :4

for inspection and removal and insertion of parts and for filling the reservoir and for cleaning and flushing the tank, and the baiile 23 prevents escape of the penetrant liquid. The drip pan 2! deflects liquid from the lower grille beyond the battle 23.

By using the spray heads in pairs I am able to get a much more uniform action in a relatively small space. fine spray more like a mist thanlike a stream. The spray from these two heads intersects and fills the adjacent space so as to completely envelop the falling' bobbins.

Proper conditioning of the yarn requires control of the solution applied to it. This is accom plished by adjustment of the regulating valve between the circulating pump and the spray heads, by using proper capacity of heads, adjustment of the orifice of each spray headsoas to produce the desired enveloping mist and by modifying or properly designing the contact areas of the inclined grilles or grids. As the bobbins roll down these grids they come in contact with the surfaces which are wet from the spray and thus pick up moisture by contact. Intact in some cases part of the baffles or grids may be covered with imperforate'plates so that more liquid may be picked up.

Another important feature is the removal of excessive moisture which might fall in large drops like rain from the lower edge of the.upper baiile to the bobbins as they pass down the lower battle. This would cause the yarn to become spotted or excessively wet in spots. This trouble has been overcome by the use of a gutter to lead the excess moisture out of the path of the falling bobbins.

The grids may be satisfactorily formed oi. hard, non-corrosive metal such as Monel metal or stainless steel held properly in place and preferably readily removable. The solid covers for the grids may be formed of Micarta or non-corrosive metal not affected by the penetrant liquid.

The apparatus herein set forth is very simple in construction and durable. The original cost is very much less than any known prior art yarn conditioning machine. In fact the cost or replacement and repair is only a small fraction 01 the cost of upkeep of machines which employ moving aprons or drums, and the result of the process is a better conditioned package.

One great advantage of the present apparatus is that the yarn is better and more uniformly conditioned because of the rolling, turning motion as the bobbins descend the inclined grids and baillcs and retain their spinning motion while falling through space. The entire circumference of each package is thus exposed to the iine spray and uniform wettingtakes place; The operationalso takes place at a higher speed as the bobbins pass quickly through the treating chamber. There is Each head or nozzle produces a' 4 no way for the bobbins to get caught. The wooden bobbins or spools do not have a chance to become soaked either on the outside or inside which soaking would tend to cause the bobbins to swell and crack and deteriorate.
