DRS. BLACK’S CANADIAN / AMERICAN CUPPING APPARATUS, c. 1895. The 10″ (25 cm) long fitted walnut case contains a gutta percha hand piston pump and two screw-on molded glass bleeding cups with gutta percha fittings. The large printed trade label in the case identifies the inventors as Drs. W.S. & F. Black, and the maker as Wm. B. Stewart of Box 646, Trenton, N.J. Condition is fine but some accessories are lacking. It appears that Fergus Black, resident of Uxbridge in Ontario in Canada, received U.S. Patent 514,900 for this improved air pump. An uncommon phlebotomy device.
