White Metal Alloys Question: Please give me the composition of the metal used for lining the cross-head slides, rod-brasses, etc.-J. E. B.
Answers: An alloy composed of the following is commonly used for lining the cross-head slides:
Lead, 65 parts; antimony, 25 parts; copper, 10 parts. The above is also used for rodbrasses and axle bearings. Some object to white metal containing lead or zinc. It has been found, however, that lead and zinc have properties of great use in these alloys.
In the German Navy, the following alloy is used:
Tin, 85 parts; antimony, 7/2 parts; copper, 77/2 parts.
Oil Filters Question: With sponges, hay, and burlap screens placed in filter, the cylinder oil still deposits on the crowns of boilers. Kindly publish in The TECHNICAL WORLD, a remedy for same.-W. C. E.
Answer: With the somewhat limited information which you have given, it is hardly possible to give a remedy for the trouble you mention. We do not know whether you are using a standard filter of some manufacturer, or whether it is a built-up filter of your own make. In any case, the only suggestion we could offer at the present is that you should renew the hay, burlap, and other substances used, whenever they become saturated with the oil. We think that in the present instance, your trouble may be due to using saturated screens.
