. Railway mechanical engineer . h. While this car is designed particularly for handling pas-sengers, express, mail and baggage on short and branch linesteam railways, it was also adapted for use on suburbanelectric lines where the cost of power is excessive. In newconstruction, the gasoline motor cars have important ad-vantages over electric cars, eliminating the necessity foroverhead wiring and the extra cost for the installation andmaintenance of power stations. A Combined Car Coupler and Hose Connector Operating Principle and Construction of Cou-pler Differ Radically from Present Standard A COMBINED car coupler and automatic steam and airhose connector in the design of which a completedeparture has been made from the operating princi-ple of the present standard vertical plane coupler, hasrecently been placed in service on a number of steam railwaypassenger cars. The device, which has been developed bythe Universal Car and Hose Coupler Company, St. Louis,Mo., provides for no vertical adjustment between the coupler. 1 tH/ c General Arrangement of the Universal Car and Hose Coupler heads and the hose connector blocks are directly connectedto the car coupler head. The operating principle of the coupler is clearly shown inthe illustrations. From the drawing, which shows two ofthe devices coupled together, it will be seen that vertical andlateral adjustments are provided for by an intermediate sec-tion of the draw bar, hinged to the main draw bar by a largerhorizontal pin. To the end of this the coupler head in turnis attached by a vertical pin connection. When uncoupledthe coupler head is supported approximately in a horizontalposition by means of a vertical coil spring acting on an ex-tension from the lower side of the intermediate draw bar. The coupler head presents a rectangular bearing facemeasuring approximately 11 in. vertically by 16 in. wideover all, the width of the bearing surface being about 1^4 m-From the left half of the rectangle enclosed by this bearing
