^™f* .\s ^^ ^ 1 ^H 7^m FIG. 4.—MACHINE FOR MAKING BRONZE BEARINGS of the different moulds. Although the surface of the face-plate is perfectly smooth and at right angles to the shaft I,it was found, nevertheless, that a spring action is necessarybetween the two, owing to the fine fins that are liable to format the edge of the gate. Each casting requires a mould espe-cially designed for its own requirements, as the part of themould against which the heavier part of the casting is maderequires a greater chilling eftect, and for this reason must bemade of metal having a greater chilling capacity. In theseexperiments, for the sake ,of comparing the different metalsand alloys for their chill effect, it was assumed that theproduct of the co-efiicient of heat conductivity multiplied intothe specific heat of any one metal or alloy represented therelative value of its chill effect. All results seemed toverify the correctness of this assumption. ♦-♦> CONVERTIBLE CARS FOR ROANOKE, VA.

CONVERTIBLE CAR FOR RoANoKE, VA. rod Z are so placed that, if the tilting were not increased.(hie to the eccentric W, the entire mould would fill while themetal was flowing jjarallcl to this cylindrical part. It is ob-vious, hf)vvever, that it would be impossible to fill a mouldcompletely under these conditions, and therefore it is neces-sary that the tilting of the mould be gradually increased bysome sucii means as the eccentric W. This causes the end of The accompanying illustration shows a convertible car re-cently put in o)ieration by the Roanoke Railway & ElectricCompany, and received from the J. G. BrillCompany.
