Anti-pest Doorbell Discourages Agents and Bill Collectors
A RECENTLY invented doorbell of the coin-in-the-slot type is finding great favor with housewives who are continually pestered by salesmen and bill collectors.
A dime must be inserted in the slot of this unit before the push button can be made to operate the bell. If the visitor is unwelcome, he or she loses the dime, but if a friend calls the housewife returns the dime after opening the door.
Agents are a bit hesitant about entering homes equipped with this doorbell, for they are not always confident that they can persuade the lady of the house to buy their products or return the dime.
Movie stars especially, who are continually bothered by autograph seekers and salesmen, are finding that this tittle device adds considerably to their income.
