Whena locomotive is standing the ball is on itsseat, and allows no air to pass.

Bench Hose Venting Device. By J. A, Jesson, Louisville & NashvilleRailroad, Corbin, Ky. The accompanying diagrammatic illus-tration shows the details of an automaticair blast, adapted for attachment to theshop bench. It consists of a discardedfeed valve, a feed valve bracket, and a.

In the event ofthe throttle vaive connections becomingdisconnected while the valve is closed,there is a set screw in the cylinder headof the supplemental valve that can beturned in and hold the valve off its seat,destroying the automatic feature of thedevice. Then the flow of steam can becontrolled by the admission valve, and anengine can be brought to terminal underits own steam. The reducing valve connected to theindependent brake in the E. T. equipment,or signal line can be used to supply airto the device thereby eliminating the useof an additional feed valve. The air con-nection could also connect to the train-line in passenger service and in casean emergency arose where it to make an emergency applica-of the brakes, and deplete the trainline,air would be drawn from the ball valvealso and allowing tlie a
