T all whom it md-y conc-emi: Be 1t knownthat I, SErn A. CRONE, a citizen'of the United States, and a resident of NewYork (sity, in the county ofNevv York4 and State! of New. York, have invented' certain -new and useful Improvements in. vRail,- Way- Carv Brake-'qhoea of which the follow#A ing 1s a specification.

The invention relates to' Aimprovements in brake-shoes; and it consists in the novelv features hereinafter described, and particutheforge'd-.metal'back The back 11' isinone 1n and preferablygbeing less in Width than-. saidf '.saidfbody being, as usual, of ca'st meta '-'lboX-'loopl-Z and '5 5' site sideedgesftvith inwardly depressed porlarly pointed 'outjin the claims.
