I wonder if it was what can be found via GoogleBooks:
'The London Journal of Arts & Sciences (and repertory of patent inventions'  page 115
which tells of a  patent taken out in that same year for a device for communicating on railway carriages... also could be used as a station bell, alarm bell,or in stable yards, porters' lodges etc
