A. MARR SOUND REPRODUCING LNSTRUMENT Flled July 9 1924 Inwen t0 r Patented Oct. 26, 1926.

UNITED 'l'A'llTlS MMJEE SOUND-REPEODUCING INSTRUMENT.

Application filed July 9, 19-24, Serial No. 724,940, and in Great Britain July 23, 1923.

This invention relates to sound reproducing instruments, and has for its object to provide a single telephone receiver capable of binaural use.

i In the accompanying drawings Fig. 1 is an elevation showing the invention as applied to a telephone receiver for use with wireless receiving apparatus, Fig. 2 is a sec tional elevation, and Fig.8 is a plan.

Referring to the drawings. 4 is the telephone receiver having a special cap 5 with a hollow extension 6 which has diametrically opposite holes 7 in which short tubes 8 are secured.

The projecting ends of the tubes 8 are adapted to receive the ends of the flexible tubes 9 on the other ends 01": which ear pieces 10 are mounted by means of short tubular extensions 11. Conveniently the ear pieces 10 have curved hook like flanges 12 adapted to take over he ears out the wearer.

lVithin the flexible tubes 8 is a length of wire 13 which in comparison with the tube is rigid; and has sufficient resiliency and is shaped so as to urge the ear pieces toward each other so that when the device is put on the head the ear pieces will be held tightly in position. This ire 13 further aids in the clear transmission of sounds.

Instead of using the tubes 8 on the hollow extension 6, the flexible tube 9 may be made in one piece and passed through the holes in which the t-ubesSare secured,after which the flexible tube is secured and its portion within the hollow extension is cut away.

What I claim as my invention and desire to secure by Letters Patent is 1. A binaural telephone receiver comprising a single telephone receiver, a cap to said receiver constituting a sound chamher diametrically opposite openings in the wall of said chamber, flexible tubes connected with said openings and provided at their free ends with car pieces, a resilient body arranged in the bore of said flexible tubes and crossing said sound chamber, the ends of said resilient body contacting with said ear pieces, said resilient body being of suiiicient stiliness to urge said ear pieces toward each other to prevent collapse of said flexible tubes.

2. A binaural telephone receiver comprising a single telephone receiver, a cap to said receiver constituting a sound chamber, diametrically opposite openings in the Wall of said chan'iber, flexible tubes connected with said openings and provided at their free ends with hook-like ear ieoes, a resilient body arranged in the ore of said flexible tubes and crossing said sound chamber the endsof said resilient body contacting with said ear pieces, said resilient body being of .suliicient stiffness to urge said ear pieces toward each other to prevent collapse of said flexible tubes and aid in the transmission of sounds.

In witness whereof I have hereunto set my hand.

ALEXANDER MARK.
