signor to American Johnson City, Tenn., as-

Glanzstofi Corporation,

New York, N. Y., a Corporation of Delaware Application December 16, 1931 Serial No. 581,496 I 2 Claims.

My present invention relates to a new type of gasket or fitting adapted primarily for use in a washing or treating apparatus.

In the manufacture of artificial threads or filaments and the like by the viscose process the threads or filaments are wound on perforated or foraminated bobbins or spools and are then subjectedto a liquid treatment. This treatment is accomplished by passing liquids through the body of the threads or filaments by the application of pressure or vacuum. The bobbins or spools are arranged in stacks in a tank, each stack fitting over an opening in the bottom of the tank and the treating liquid is forced through the opening into the interior of the bobbin or spools; through the openings formed therein, through the yarn body and thence into the tank. When a vacuum system is used the flow of the liquid is in the reverse direction.

One object of my present invention is to provide a suitable means for centering the bobbins or spools over the openings in the tank.

Another object of my invention is to provide a new arrangement for centering and calking the stacks of bobbins or spools so that the loss of pressure or vacuum will be reduced to a minimum.

A further object of my invention is to provide a suitable centering and calking arrangement which may be easily assembled and disassembled and which functions more emciently than those now in use. v

These and other objects will become more ap parentfrom a study of the following description 5 and the drawing in which:

Fig. 1 is a sectional View of my device;

Fig. 2 is a top plan View of the gasket;

Fig. 3 is a sectional view of the gasket taken along the lines 3-3 of Figure 2; and i Fig. 4 is asectional View of the tube forming part of the-device.

Referring now more particularly to the drawing I have shown in detail a preferred embodiment of my invention. My device consists essentially of a two part centering and calking arrangement and oomprises a tube made of a heat and acid'resistant material. The tube is substantially cylindrical in shape and is provided at one end with a flange 11 having a beveled or inclined portion -12-. As is clearly shown in Fig. 4 the tube is provided with a threaded portion -13' which is spaced from the flange leaving a smooth surface -14-. The lower end of the tube is cut away to form a shoulder -15 leaving a smooth neck like portion -16- adapted to receive a tube or hosing connecting the device to a vacuum or pressure system.

The gasket comprises a circular member -1'7- having a central opening 18- formed therein. 50 The inner wall thereof is out as shown at 19- forming a, shoulder -20--. The shape of this cut-away portion corresponds to the shape of the flange of the tube and the shoulder -20- fits snugly against the smooth portion -l4- ;5 formed on the tube. The gasket may be made of soft rubber or other suitable material.

The top of thegasket is provided with a plurality of radially disposed grooves or slots --21-- which communicate with the central openingl By this construction all of the water or treating liquids will be drained towards the center of the device. To facilitate this draining the tube itself is formed with a countersunk portion -22-;

In assembling the device the flanged end of the {'1 tube is fitted in'the cut-away portion formed in I the gasket as is clearlyshown in Fig. 1. The

tube is then passed through the opening --23-- formed in the tank -2iand is secured thereto by means of a suitable lock-nut -25-- threadedg on the threaded portion of the tube. The shoulder -20- is thus held firmly against the bottom of the tank forming an efiective seal between the bottom of bobbin or spool placed in the gasket and the tank. The size of the gasket is such that'l8 the inner wall of the spool snugly engages the sides thereof.

From the above description it will be appreciated that I have provided a device which may readily be assembled and secured in the tank- The tube may be made of any suitable material which will withstand a temperature of at least C. and the action of the acids which may be present in the treating liquids used;

With the fittings now in use, when any part thereof is injured or otherwise rendered useless,

the entire fitting becomes worthless and must be discarded making such fittingsvery costly. By using a two part construction the gasket portion which is usually that portion of the fitting which becomes worn first, may readily be replaced thus avoiding the replacement of the entire fitting.

The-provision of the drainage openings in the gasket prevents the accumulation of the treating liquid around the. base of the lowermost spo0lpreventing the deterioration of the spool and the thread at that point caused by the action of the treating liquids thereon.

While I have illustrated what I believe to be aw preferred embodiment of my invention it is ob--"- I vious that various changes and alterations might be made in the general form of the parts described Without departing from my invention and hence I do not limit myself to the precise details set forth but consider myself at liberty to make such changes and alterations as fairly fall Within the spirit and scope of the appended claims.

What I claim as new is:

1. In a treating tank having an opening formed in the bottom thereof, a device for securing and centering spools over said opening comprising, in combination, a tube-like member having a flanged upper end and a threaded portion, a gasket fitting around said flanged end and having spaced drainage slots formed therein, said tube and a lock-nut engaging to secure said device in RICHARD J.
