The loss ofthe cover while running means a hot pin, and the loss of theentire cup and cover by thievery is a common occurrence whichIs explained by the present high price of copper and brass covers often become lost and they are usually re-placed by tin; on one road, the New York Central, pressedsteel is being considered for covers for cups where the coversmay be slipped on without requiring a screw cap for rods, malleable iron oil cups have been used for severalyears, and they are satisfactory in every way. The form illus-trated was put into use on the Central Railroad of New Jerseyabout a year ago. It Is cheap, efflclent and looks well. The ^!^i.

Malleable Iron Oil Cups. interesting features are the long tube at the bottom whichtakes the oil down into contact with the crank pin, the form ofthe base whereby a secure fastening to the rod is obtainedand an excellent device for regulating the flow of oil. In manycups the tube at the bottom terminates with the threaded por-tion and this permits the oil to pass between the brass andthe rod, while this long tube carries each drop down upon thepin itself. The form of the bottom of the cup is seen in thesectional views. It is thinned down in such a way as to obtainthe assistance of the elasticity of the bottom of the cup tohold it against turning back after it has been screwed downfirmly. To this feature Mr. Mcintosh attributes the entirefreedom from loss of the cups by
