Referring to .the arts are designated by the same referencesign wherever they occunl indicates the va- 'rious receivers of an acousticon set, each of which is secured opposite a suitahleopening To all whom it may concern:

Be it known. that I, HOWELL W. HAFF, a citizen of the United States, residing at Babylon, in the county of Suiiolk and St ate of New York, have invented certain new and useful Improvements in Connection for Acoustic'ons, of which the following is a full, clear, and ex-' act description. in the box 2 and which has a pair of terminal My invention relates to an arrangement wires 3 4. it is obvious that as many reto for connecting the jvarious receivers of an 'ceiversl may be providedv as are necessary 1n acousticon to the battery wires or terminals.

It is not less important to have the connected to the arms 9 of the lower plate, various instruments separately removable while the terminals 5 are secured to the arms 9 5 for the purpose of adjustment or in order to 6 I have shown screws 15 for making the substitute a new instrument.
