It is an object of our invention to provide a waterproof cover or casing "for electrical conneotion known in the trade as a .radio' jack. Of course, this invention maybe used "with any similar electrical connection lfor vvat'erproofing purposes.

It is an object of this invention to provide a simple waterproof casing having a pivoted closure or plug spring actuated to-opening or closing position.

It is an object of this invention to provide a closure casing or cover that may be readily attached to a radio jack or similar connection.

Other objects, features of novelty and advantages will-be revealed in the following description given in connection with the attached drawings displaying the preferred embodiment in the following figures:

Fig. 1 is a side elevation of our completed invention ready for attachment to a radio jack or-similar electrical connecting element.

Fig. 2 is a section taken centrally and: dia metrically in a vertical plane through the whole device including the spring actuating feature thereof;

Fig. 3 is a plan view of our invention displayed in Fig. 1.

Fig. 4 is an elevation of our invention in open condition.

This waterproof casing or housing may be used in any environment where electrical connections may be wetted by water or any other liquid elec trolyte or conductor of electricity. This device is especially'useful and advantageous in connection with radio equipment and similar equipment used on boats, ships and particularly in landing boats or barges. It appears to be self-evident that this invention has an extensive field of essential application wherever protective Waterproof housings or casings are needed in. connection with electrical equipment which is subject to being wetted by a liquid that may become a conductor of electricity.

The housing or protective casing for shielding anelectrical elementfrom the entrance of water is generally and completely designated by I. The flanged tubular member 2 is provided with an inturned flange 4 defining a diaphragm having an apertured portion 8. The opposite end :of the tubular portion 2 has an imperforate inturne'd flange 2 defining an-apertured base portioni in axial alignment with the apertured portion -8. The apertured portion 3 is adapted to receive the threaded tubular endof a radio 'ja'ck J. The "radio jack is provided with a shoulder to engage the inside of a casing or panel and is secured in such position by a nut screw threaded on the threaded tubular extension of the jack. To attach our unique protecting and shielding c asing or housing, it is merely necessary "to unscrew the nut, apply a rubber Washer R and then the apertured end or base 2', 3 of the member 2 is secured in position by a reapplication of the screw threaded nut to the threaded tubular portion of the jack.

The radio jack J shown inF-ig. 2, is-discl'osed in the patent to Carter, 1,620,755, granted Mar-ch 15, 1927.

More specifically the flanged tubular member 2 comprises a comparatively soft rubber diaphragm 4 having a skirtor rimi position-edand secured to the upper end 8 of the flanged tubular element or portion 2; 2"and 3 by theuse ofa clamping ring 1. The ring I is preferably an endless helically coiled spring which tightly clamps the rim 5 to the end portion 6 of the apertured tubular element or portion 2,-2; 3 and '6.

The diaphragm '4 is provided with an'apertured portion 8 located axially in substantial alignment with the apertured portion 2 and 3 of the flanged tubular element 2. The diaphragm 4 is preferably tapered to a thin flexible resilient edge portion defining the ape'r'tured portion fl thereof.

The plug member 9 is provided with a manipulating handle or knob 1'9. The plug member 9 like the diaphragm 4 and skirt 5 in made of yieldable material such as rubber or rubbercom-- position or the like. The plug H per se is ro vided with two necked portions or annular grooves I2 and I3. A yieldable annular tapered projection is adapted to yieldingly engage the diaphragm 4.

The tubular member I 2 is *connected to the plug member '9. The preferred connecting means comprises hinge leaves or parts l5 and I 6. The leaf or part [5 embraces the tubular member 2 and is provided with U-shatped portions ll at substantially a right angle to the remainder of the leaf or'part |'5,'saidU-shape'd portions, having out turned portions [8. The bightportions l9 engage a pintle 20 having heads 2|.

The -U-shaped portions ll supporta helieal spring 22. One end of the spring '22 engages the leaf or part l5 and the projection lt The other end of the spring 22 supports a washer 23.

The leaf or part I 6 embraces the plug 9 and its ends are provided with about one andonefourth convolutio'ns 24'- surrounding tlie 'piritle lll and terminating in-substannany-tangential pmjections 25 engaging the free face of the spring actuated washer 23. The spring actuated washer urges the plug member a to closed position by the tension of the compressed helical spring 22. When the plug 9 is pulled open the projections 25 slide over the free face of the washer 23 from one side of the pintle 252 to the other side of said pintle. While this operation is performed the washer 23 is depressed against the tension of the helical compression spring 22. The spring 22 cooperating with the washer 23 and the pro-- jections 25 maintain the plug member 9 in either an open position or a closed position according to the results required by manipulation.

The tubular portion 2 is provided with a groove 3' extending substantially 340 degrees about the portion 2. The remainder of the circumference is not grooved and represents a distance of substantially 20 degrees and is indicated by a sub stantially straight vertical portion 3" defining stops,

The leaf or part 55 engages in the groove 3 and the portions of said leaf or part It including the shoulders .9 thereof are maintained in said groove 3 by the helical spring 22 which embraces the U-shaped portions ll of the leaf Hi and prevents the loop portions of said leaf from spreading apart.

Portions of the leaf or part it are provided with shoulders s which engage the adjacent ends of the groove 3 and are located in the path of the stops defined by the straight portion 3' The arranged relation of the shoulders s and the stops prevents or limits relative rotation between the leaf or part !5 and the tubular portion 2.

It will observed that the helical spring 22 performs a dual function first, by maintaining the Washer 23 in a resiliently elevated position and secondly, it maintains the loop leaf or part I5 securely in the grooved portion 3' of the tubular portion 2.

The leaves [5 and [6 of the hinge are bendable, as by the use of a pliers, so that the tubular member and plug member may be relatively adjusted With reference to each other, especially as to their axial alignment.

It is noted that the helical portions of the spring hinge which surround the pintle are provided with projections 25. These projections could be omitted since a portion of the washer 23 resiliently bears against the helical portions of the hinge and could act as a friction brake to retard the operation of the ceiling plug members l0 and H. In the slight modification suggested it is noted that it is not shown on the drawings 1 but was contemplated in the original disclosure as clearly indicated in original claim 17.
