Abstract
Abstract Apparatus for acoustically coupling facsimile signals through a telephone handset to a telephone network. A loading arm engageable with the telephone handset biases the telephone speaker into intimate relationship with a receive transducer adapted to convert acoustical signals into electrical signals. A send transducer for converting electrical signals into acoustical signals is biased into intimate relationship with the telephone microphone by means of a resiliently deflectable support adapted to assume variable orientation with respect to the receive transducer and the telephone speaker.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
145 words
Apparatus for coupling a facsimile transceiver to a telephone network through a telephone handset having speaker and microphone portions comprising: first transducer means for converting acoustical signals from said telephone handset into electrical signals, second transducer means for converting electrical signals from a facsimile transceiver into acoustical signals, a first support member for mounting said first transducer means, a second support member for mounting said second transducer means, a support plate having a plurality of apertures for supporting said second support member, and a plurality of guide members affixed to a third support member and each having a resilient means positioned thereon, said guide members being positioned through the associated support plate aperture, the arrangement of said support plate on said guide members permitting said second support member to conform to the orientation of said microphone portion irrespective of the orientation of said speaker portion.
Claim 2
Dependent Claim
145 words
Apparatus for coupling a facsimile transceiver to a telephone network through a telephone handset having speaker and microphone portions comprising: first transducer means for converting acoustical signals from said telephone handset into electrical signals, second transducer means for converting electrical signals from a facsimile transceiver into acoustical signals, a first support member for mounting said first transducer means, a second support member for mounting said second transducer means, a support plate having a plurality of apertures for supporting said second support member, and a plurality of guide members affixed to a third support member and each having a resilient means positioned thereon, said guide members being positioned through the associated support plate aperture, the arrangement of said support plate on said guide members permitting said second support member to conform to the orientation of said microphone portion irrespective of the orientation of said speaker portion.
Claim 3
Dependent Claim
65 words
The coupling apparatus as defined in claim 1 further including a loading arm pivotally connected to a fourth support member extending from a base member for engagement with said telephone headset, said loading arm being deflectable along the length of said handset to apply tension thereto, thereby biasing said speaker portion toward said first transducer means and said microphone portion toward said second transducer means.
Claim 4
Dependent Claim
114 words
The coupling apparatus as defined in claim 2 wherein said first and second support members each include an acoustically insulating, deformable material overlying the outer periphery of the operative faces of said transducer means, the tension exerted by said loading arm against said telephone handset being sufficient to slightly deform said insulating material against the face of said speaker and microphone portions to insulate said first and second transducer means and said speaker and microphone portions, respectively, from ambient acoustical energies, said tension exerted by said loading arm further being sufficient to permit said second support member to conform to the orientation of said microphone portion irrespective of the orientation of said speaker portion.
