We reproducesome of these as follows: It locks automatically and when locked, owing to its positivefastening, the door is held tight against the bottom of the hop-per, and sagging down is impossible. All of its attachments and fastenings are outside of the hop-per, and when open, outside of the path of the load, removingany danger of damage from the load in passing out. These attachments being outside of the hopper makes it easyto open or close the door in all kinds of weather. In fact, a.

In opening, the doors do not approach much nearer the trackthan in the closed position and are therefore not apt to bedamaged if left open. As the doors do not swing down toward the track, the widthof the hopper opening is not limited by this distance, and ifnecessary a much wider opening can be secured. It may be applied to the ordinary style of hopper and doesnot require any change in the construction of the car. FIREROOMS IN THE TROPICS.
