York city, in the borough of Manhattan and;

State of New York, have invented certain new and useful Improvements in Attachments for Acousticons Permitting Use of Ordinary Telephones, of which the following is a full, clear, and exact description.

My invention relates to a telephonic attachment by means of which deaf persons are not only able to hear ordinary conversation, but may converse over the telephone as'well. The invention hasparticular reference to use, with the acousticon, an instrument which employs a special form of transmitter ada ted to be carried in the vest' or coat poc et and which multiples the sound directed against it, so that a deaf person may understand the same. For this pur ose said transmitter is connected in a telep one-circuit with a receiver, which the person places against his ear when he wishes to converse. These articles are sold upon the market and are carried by deaf persons for-constant use.

The aim of my present invention is to provide an additional attachment by which the above outfit is made adaptable to receive conversation and sounds over the usual telephones. I these and other objects in view my invention consists in the construction, combination, in the location, and in the arrange.- ment of parts, as hereinafter set forth and shown and finally particularly pointed out in the applended claims.

In t e drawings, Figure 1 illustrates the manner of use of an outfit embodying my invention. I Fig. 2 is a front view of my attachment. Fig. 3 is a side view of theattachment, showing the same in position to be Zpplied to the-acousticon-transmitter.- Fig.

ows the device in its operative relation to a telephone-receiver.

Deaf persons are ordinarily more seriously inconvenienced by their inability to receive telephone messages than by any other relation. This is by reason of the fact that the loudness of telephone transmision cannot be increased on the ordinary instruments Without setting up violent vibrations of the telephonic diaphragms, which destroy the purity 'of the sound. By my present invention I provide means by which the sound delivered from an ordinary telephone-receiver is retransmitted into a form of transmitter adapted to multiply the sound and from which it can be readily heard in a special local circuit provided by the acousticon apparatus.

Referring to the drawings and to the va-' rious views and reference-signs thereof, in which like parts are designated by the same reference-sign wherever they occur, A indicates an ordinary desk-telephone outfit comprising a transmitter A .and a receiver A B indicates an acousticon outfit, including an acousticon-transmitter B and an acousticon-receiver B The usual form of the acousticon-transmitter is illustrated in Fig. 8, it being commonly provided with a hook or clasp b, by which it is secured to the vest or coat pocket in use.

In its preferred form my invention includes a ring or annular casing 1, having a straight cylindrical portion 2 and an end face "3, centrally perforated with a hole 4 of sufficient diameter to receive the end of the ordinary telephone-recelver A, as shown 1n Fig.

4. The straight cylindrical portion or run terminates in a circular edge 5, which hes in a flat surface or plane, so as to be capable of closely engaging the face of the acousticontransmitter B.

6 indicates s ring-prongs secured around the rim 2 and w lii the acousticon-transmitter B, so as to hold the two members closely together.

The use and operation are as follows: Normally a deaf person will be provided with the acousticon outfit, and will proceed with his regular vocations and pursuits with the acousticon-transmitter B hooked upon the pocket of the vest or coat or otherwise conveniently disposed to receive the conversation. When the deaf person goes to a telephone, the device embodying the present invention is placed u on the acousticon-trans- .mitter, where it is eld by the pron s 6. It

is then merely necessary to press t e usual telephone-receiver'into the opening 4 of the rlng or casing 1, whereby a chamber is proch engage over the sides of duced into which 1e sounds from the receiver are gathered and confined. All the sound of the telephone-receiver is therefore im elled into the acousticon-transmitter B, an by which it is multiplied and retransmitted, so as to be received by the deaf person in the usual way.

What I claim is-- l 1. An attachment for use with the acoustlcon comprlslng a ring or annular casing TIO formed to fit closely upon the face of an acousticon-transmitter, and having a hole or perforation to receive the usual receiver of a telephone outfit.

2. An attachment for use with the acousticon, comprising a casing having a strai ht cylindrical portion or rim and an end wal or face having a hole or erforation therein, s'aid erforation being a apted to receive the usual receiver of a telephone outfit, and means upon said rim for securing the casing to an acousticon-transmitter.
