2 Claims.

The present invention relates to water barriers particularly to those at the feed end of the water-trough from an extruder for cables or the like.

"Difficulties have been encountered at the feed endof the water-trough from extruders in introducing the cable or any other object at the feed end of the water-trough with the minimum loss of water.

It is, therefore, the object of the present invention to provide means for providing a water barrier at the feed end of the water-trough.

It is another object of the present invention to provide a water barrier of simple construction which allows easy adjustment and separation of all elements. a

With these and other objects in View the present invention will become apparent and clearly understood in connection with the following description and the drawings, in which:

Figure 1 is an elevational end view of the water barrier;

Fig. 2 is a top view of the water barrier shown in Fig. 1;

Fig. 3 is a sectional view along the lines 3-3 of Fig. 1; and

Fig. 4 is a sectional view along the lines 4-4 of Fig. 1 showing a cable inserted in the water barrier.

Referring now to the drawings the water barrier according to the present invention consists of a U-shaped front plate I substantially following the end flange 2 of a water-trough 3. The flange 2 and the plate I are equipped with a number of coordinated holes 4 adapted to receive screw bolts (not shown) in order to secure the plate I to the flange 2. The plate I is further equipped with a number of threaded borings 5 which receive wing screws 6 which are adapted for attachment of guide strips I of L-shaped crosssection to the plate I. On front of the plate I another U-shaped plate 8 is provided between the two guide strips I screwed to the plate I and kept in properly leveled position by tightening the wing screws 6. The leg portions of the U-shaped plate 8 are equipped with a number of threaded borings 9 which receive screws I0 which secure another pair of strips II to the U-shaped plate 8. The top of the base of the U- shaped plate 8 has a half circular cutout I2 and around this cutout three threaded borings I3 preferably in triangular arrangement are provided adapted to receive screws I4 the purpose of which will be described later.

Into the open space of the U-shaped plate 8 and held between the plate I and the strips I I is inserted another substantially rectangularly shaped plate I5. The bottom of plate I5 has also a half circular cutout I6 of a diameter corresponding with the diameter of the cutout -I2 in plate 8. By this arrangement of the two cutouts I2 and It the plates 8 and I5 provide together a circular opening into the watertrough 3. The plate I5 is also equipped with three threaded borings I! which receive screws I8 adapted for a purpose to be described later.-

A smaller substantially rectangularly shaped flexible cover I3 is provided in front of the bottom of the plate I5, which cover has three holes 20 in an arrangement corresponding to the three threa'dedborings I I of plate I 5. The COVGI'IIB has an extension 2| of a width corresponding with the diameter of the circular opening formed by plates 8 and I5. The cover I9 is also equipped with a vertical slot 22 extending upwardsfrom the center of its lower margin for a length shorter than the radius of the circular opening.

A second cover 23 is provided in front of the top of the base of the U-shaped plate 8'covering the half circular cutout of the plate-8. :The cover 23 is formed exactly like cover I9 except it is not provided with an extension as disclosed before in connection with cover I9. Thus cover 23 has also three holes 24 arranged corresponding with the threaded borings I3 in the plate 8. A vertical slot 25 is also provided extending from the center of the upper margin of the cover 23 downwards, however, for a length shorter than the radius of the previously mentioned circular opening in plates 8 and I5.

The two covers l9 and 23 cover entirely the circular opening formed by the plates 8 and I5 whereby the extension 2I of the cover I9 overlaps inwards a portion of the upper margin of the cover 23.

Two additional preferably rectangular covers 26 and 2! of the same size as the above described cover 23 are provided namely the cover 26 in front of the cover I9 and the cover 27 in front of the cover 23. Both covers 26 and 21 have also three holes 28 and 29, respectively, corresponding with the threaded borings I3 and H of the plates '8 and I5, respectively. The upper cover 26 has two slots 30 extending from its lower center at an angle of 45 upwards and the lower plate 21 has corresponding slots'3I extending from the upper center downwards at an angle of about 45. The covers I9, 23, 28 and 27 are made of rubber, vinylite or any other similar flexible material. In front of the covers again with three holes 34 in an arrangement corresponding with the three threaded borings H of the plate 15. The upper plate 32 has further a half circularcutout 350i a diameter corresponding with the diameter of the half circular cutout in plate H5. The lower metal plate 33 has also three holes 36 corresponding with the three threaded borings l3 of the plate '8 as well as a half circular cutout '36 of the same diameter as the half circular cutout of 'the plate 8.

As stated above the threaded borings l3 and 11, respectively, are adapted to receive screws M and 18, respectively, the screws I4 penetrating the holes of the metal plate 33, of the cover 21, and

-;:of :thecover 23 and then to be screwedinto the -.;threaded borings 13 of the plate .8, whereas the :screws 18 penetrating thezholes of the metal plate 32,;of the cover 26,.and of the cover l9.and then ito lie-screwed into-the threaded borings ll of the :plate 1 5, so thatallcovers and front metal plates *arescrewed to the respective plates 8 and 15 by -means of the same screws l4 and 18, respectively.

: -This arrangementleaves a circular opening on xthesoutside of the plate as well as on its inside,

this opening .being closed up by the respective icovers which -.are provided with slots extending from the center of the circular opening. This arrangement allows .theintrusion of a cable into the trough by opening the-slots .of the different ecovers, the latter providing a tight fit around .thecable-which will avoid anyiloss of water out :of the, trough.

. The-construction according to the ,present inyention has as a particular feature that every -oneof'the elements and particularly the covers which will 'besubjected to wear can easilybe sep- Faratedmand exchanged and also can easily be :;adjusted. ,By providing guides for the difierent pla1tes it is also possible to adjust the center "of 2the;;opening on difierent desired levels.

While I have disclosed the principles of my invention in connection with a single embodiment, it will be understood that this embodiment is given by way of example only and not as limiting the scope of the invention as set forth in the objects and the appended claims.

What I claim is:

1. A cover forming a water seal while permitting the passage of a cylindrical body, comprising two rigid plate members formed with aligned holes, to accommodate said body, and a plurality of flexible diaphragms clamped between said plate members and formed of two parts each, including a first diaphragm adjacent one of said plate members having one part which extends substantially to the center of said holes and having another part formed with an extension lying within the hole of said one plate and extending across the width of said hole, said extension overlapping the edge of said one part, and further including a second diaphragm having two parts with abutting edges, said diaphragms :being formedwith slots extending radially of said holes but less than the full diameter thereof, in such a manner that the slots in .said first diaphragm are staggered with respect to :thosein-said-second ,diaphragm.

'2. ,A cover according to claim -1 wherein each of said plate members comprises two abutting .parts having 1 complementary cutouts :to form -;the said hole.
