" RECEIVER-CASE.

.To all 'whom @'17 may concern.'

Be it known that i, HENRY C. EoERroN, a citizen of the United States, residing at Passaic, in the county of Passaic and State of New Jersey, have invented certain new and useful improvements in Receiver-Cases, of which the following is a full, clear, concise, and exact description.

This invention relates to receiver cases and more particularlyto those provided with a plurality of independent and separable chambers.

The object of this invention is the provision of a` receiver case, having a magnet chamber self-contained and independent of another self-contained structure by means of which said magnet chamber may be removably mounted.

`in accordance with this invention, there is provided a magnet chamber consisting of two hollow metal sections having a' gasket interposed therebetween, i thus making a moisture-proof receptacle for the receiver magnet. Coperating with he magnet chamber is a condulet, comprising a hollow structure having a plurality of openings. One of said openings is closed by said magnet chamber being placed thereover, and the joint formed thereby is made moisture-proof through the agency of a rubber gasket. The remainder of said openings are threaded to receive threads formed upon the end of a conduit. Suitable attaching means is provided with the condulet to permit its mounting in a convenient locatio In the accompanying drawing, Figure 1 is a back elevation partly in section, of a receiver case embodying` the features--oithis invention, and F ig. 2 isla side elevation of the device shown in F ig. l. l

The receiver case shown inthe drawing comprises a magnet chamber 1 formed of two hollow metallic sections 2, 3 having their edges provided with a flange 4, 5 respectively, suitable for registering with eacn other. The flange 4 has a plurality of apertures, while the flange 5 has a corresponding number of threaded recesses suitable to engage screws, which function to secure the sections 2, 3 together. interposed between the flanges 4, 5 is a rubber gasket 6 which serves to make the magnet chamber moisture-proof. An annular boss is formed upon the front of section 2, which is fitted with .reducing collars adapted to accommodate an Specification of Letters Patent.

amplifying horn. Terminals 7 and 8 are provided in the base of section 3 for connecting the electromagnet of the receiver 1n an energizing circuit.

comprising the microphone no part of this invention y element forms and may be of any The apparatus standard construction suitable for mounting within the magnet chamber 1.l

The magnet chamber l is attached to a conduletv 9, consisting of a hollow receptacle provided with a flange l0 adapted to t the base portion of section 3. A rubber gasket 11 is inserted between the engaging surfaces of the flange 10 and section 3, thereby making their union moisture-proof. The portion of the condulet 9 adjacent a flange 10 is substantially cylindrical in shape, and is provided with openings 12, l2 coinciding with its longitudinal axis. These openings are threaded for the accommodation of the threaded end of a conduit 13. If it is not desirable to attach a conduit to each of the openings 12, 12, a threaded plug 14 may be inserted into the vacant one. It will be apparent that when the various elements carried by the condulet 9 are assembled, a moisture-proof chamber is provided for housing the terminals and conductors by means of which the receiver chamber is connected in an energizing circuit. Depending from the body portion of' the condulet 9 is a plurality of legs l5 provided with openings through which screws may be inserted for fastening the receiver case in any desired location.

F rom the above it will ,be seen that a receiver case embodying the features of this invention is provided with two separate selfcontained moisture-proof chambers capable of being detached and used independent of each other or in connection with similar associated parts.

What is claimed is:

l. in a receiver case, the combination with a magnet chamber, of a condulet consisting of a hollow structure having a plurality of openings, one of said openings being completely closed by said magnet chamber positioned thereover, and another of Asaid openings adapted to receive one end of a conduit.

2. In a receiver case, the combination with a magnet chamber, of a condulet consisting of a hollow structure having a plurality of openings, one of said openings being completely closed by said chamber positioned thereover, means for making the joint hetweensaid magnet chamber and said opening moisture-proof, and another of said Aopenings adapted to receive one end of a tromagnet located Within said chamber, a

leading-out terminal for connecting said electromagnet in an energizing circuit, said terminal being secured to the base of said magnet chamber, ofa condulet consisting of a hollow structure having a plurality of openings, one of said openings being closed by said magnet chamber positioned thereover, and another of said openings adapted to receive one end of a conduit.

. 4. In acase for telephonie apparatus, the combination with an apparatus chamber of a condulet consisting of a hollow struturel having a plurality of openings, one of said openings being completely closed by a wall of said apparatus chamber positioned thereover, la leading-out terminal secured to said wall and positioned within said hollow structure, and another of said openings in said hollow structure adapted to recelve one end 0f a conduit.

In Witness whereof, I hereunto subscribe my name this 5th day of February'A. D., 1916.

HENRY c. EGERTON.
