From Binding Post to Varnish
By HOWARD S. PYLE
UP IN the cold, lonely timberlands of the north — down in the warm, tropical countries — on hundreds of ships on the seven seas, myriad tiny voices of the night bring cheer and comfort and entertainment to eager listeners. And all through proper manipulation of a few simple controls on a small wooden cabinet. It is an accomplishment to inspire awe, and we have a respect for the little cabinet that forms a medium of contact with the world about us. So faithfully and efficiently does the little mystery box serve us, that many do not stop to wonder how and where and by whom the delicate apparatus was assembled and arranged within.
The writer recently made an investigation of the manufacture of modern broadcast receiving equipment, concluding his search with a trip through one of the largest and most modern factories of the independent radio manufacturers.
The entire plant had been laid out after the policy followed by the Ford Motor Company: the raw materials are routed through a definite
manufacturing cycle. As each part is completed, it is delayed at an operating station until the arrival of the next part required in the receiver assembly. By this method as a panel progresses through the factory, various completed parts are added until the panel reaches the testing department with a completed set attached to it.
The first photograph shows the individual units being made up. The girl at the extreme right is operating an automatic screw assembling machine — a combination power-driven screw driver and socket wrench. To the left, other operators are seen with automatic rheostat winding machines. A large proportion of the special machinery found to be imperative in accurate work, has been developed within the plant.
Following the completion of the various parts, they are delivered to the assembly department, to be incorporated in the receivers at the proper stations during their progress along the assembly tables.
In the photograph on page 290 we see the first stages in the construction of a four-tube re
