The radio dealer (Apr-Sept 1922)

June, 1922 THE RADIO DEALER 35 GLOBE HEADSETS The Globe Radio Telephone Head Set is said to be a highly sensitive, balanced receiver, light weight and tested and has been made by the Globe Phone Mfg. Co. for the past twelve years. The headband is easily adjusted and is neat in appearance. The Globe Phone Mfg. Co. also makes the famous Vactuphone for the hard of hearing, said to be the most powerful and dependable hearing aid ever invented. The Vactuphone has been highly endorsed by the Valta Bureau for the Increase and Diffusion of Knowledge Relating to the Deaf, founded and indorsed by Alexander Graham Bell in 1870. The Vactuphone — the word is coined from the words vacuum-tube telephone — is the result of the work of many inventors. Bell invented the telephone ; Blake, Edison and Berliner improved the telephone transmitter; Fleming improved Edison's early discovery of the two-electrode vacuum tube which grew out of the incandescent lamp, and De Forest inserted the third electrode in the Edison-Fleming tube and thereby gave to the world its most sensitive electrical device. The Globe Vactuphone has the appearance of a leather-covered camera. The electric energy is supplied by two batteries, one operating the transmitter and heating the filament of the vacuum tube, the other operating the telephone circuit. The Vactuphone is equipped with a sound regulator. Thus the instrument may be adjusted to meet the requirements of different degrees of deafness. The user need not be concerned with technical matters, as to just how the vacuum tube functions. The transmitter may face any direction. It need not be pointed toward the source of the desired sound. It is indeed an electric hearing aid. CHARTS FOR THE TRADE Charts, showing the International Morse Code, Punctuations, Abbreviations, etc., are easily sold by retailers who know their business — because every " fan " wants to know " what the sounds mean." The chart put out by H. C. Wiley, Hartford, Conn., seems to be a real code chart because it shows the Code and everything, and with the Wiley chart in front of one, the air signals are easily read. Well worth buying — well worth selling to your customers. ARNOLD LOOSE COUPLER IMPROVED MODEL, PRICE $18.00 The most consistent piece of apparatus to hear the Radio Telephone (without distortion).
