Terminal Apparatus.

—When the construction of this line was begun, it was the intention of the Pneumatic Transit Company to use the apparatus of the Electro-Pneumatic Transit Company, at both stations, for sending and receiving carriers, and so-called working-drawings were obtained for this purpose. The sending apparatus was constructed according to the designs furnished, but, upon examination of the drawings of the receiving apparatus, it was so apparent that it would not work as intended that it was never constructed.

The writer was asked to design an automatic receiver to stop the carriers without shock upon their arrival at the stations, and to deliver them upon a table without appreciable escape of air,—something that would answer the requirements of the present plant.
