Sweethearts can tell secrets over the phone now if they use new invention
Seattle, Wash, June 26 – The death knell of “listening in” has been sounded!
A young Seattle inventor has taken the joy out of party telephone lines for he has invented a device which effectively stops busybodies from learning the secrets of “neighbors” on their ‘phone lines.
Arthur F Erickson is the man who has foiled the telephone tattle-tail and his invention, the autolock, which is an automatic telephone lockout, not only makes eavesdropping a thing of the past, but it also eliminates entirely the nerve racking noise caused by the vibrating of some intruding party’s hook. With the invention in use all other parties on the line are locked out from attracting central’s attention while the line is engaged.
The new invention is composed of a series of electric magnetic coils with movable armature contacts, the process of removing the receiver from the hook and getting a response from central automatically builds a clear line from the subscriber to the central office by making certain desired contacts and breaking other undesired contacts.
The replacing of the receiver on the hook, automatically restores the line to its original condition so that any other party on the line may be called or may place a call.
