(5.) The combination with a containing-vessel having a shoulder of a cover provided with flexible securing tongues adapted to be seamed between its ends beneath the shoulder, said tongues being weakened between the cover and the line of seaming, substantially as described. (6.) The combination with a metallic containing-vessel having its edge turned downward and then upward to form a shoulder, the outer wall of said shoulder being flattened, of a cover having a flange which extends substantially to the lower edge of the shoulder, said flange having flexible projections which are adapted to be bent beneath the shoulder, substantially as described. (7.) The combination with a metallic containing-vessel having its edge turned downward and then upward to form a shoulder, the outer wall of said shoulder being flattened, of a cover having a flange which extends substantially to the lower edge of the shoulder, said flange having tongues projecting therefrom which are narrowed at their line of juncture with the flange, substantially as described. (8.) The combination with a metallic containing-vessel having its edge turned downward and then upward to form a shoulder, the outer wall of said shoulder being flattened, of a cover having a flange which extends substantially to the lower edge of the shoulder, said flange having tongues projecting therefrom which are narrowed at their line of juncture with the flange, and the ends of the tongues being bent outward to form finger-holds, substantially as described.

No. 13407.—14th February, 1901.—LUCIEN IRA BLAKE, of Lawrence, Kansas, United States of America, Professor, and LAWRENCE NORTON MORSCHER, of Neodesha, Kansas aforesaid, Student. Process of and mechanism for separation of conductors from non-conductors.

Claims.—(1.) The described process of effecting the separation of the electric conducting particles of a mass from the non-conducting particles of the same, which consists in electrically charging the particles of such a mass by submitting the same to an electrostatic field or charge of one potential, and then subjecting such mass to an electrostatic field or charge of opposite potential, whereby the conducting and quickly electrified particles are repelled from the non-conducting particles of slow electrification. (2.) The described process of separating conducting particles from a mass of non-conducting particles, which consists in conducting a stream of the combined particles or grains through an electrostatic field of one potential, and then through an electrostatic field of another potential. (3.) An apparatus for effecting the separation of the conducting particles of a mixed mass from the non-conducting particles of the same, composed of an electrically charged repelling-surface of different potential from that of the mass, and means for conveying said mass into contact with said repelling-surface. (4.) An apparatus for effecting the separation of the conducting particles of a mixed mass from the non-conducting particles of the same, composed of a conveying-surface, a source of electrostatic energy arranged relatively thereto for imparting to the mass an electric charge, and a repelling-surface electrically charged at an opposite potential from that of the mass, and arranged to receive the charged mass. (5.) An apparatus for effecting the separation of the conducting particles of a mixed mass from the non-conducting particles of the same, composed of a conveying-surface, a source of electrostatic energy arranged relatively thereto for imparting to the mass an electric charge, and a repelling-surface electrically charged at an opposite potential from that of the mass, and arranged to receive the charged mass. (6.) An apparatus for the purpose above described, consisting of a conveying-surface, a source of electrostatic energy arranged relatively thereto for imparting to the mass an electric charge, and a moving repelling-surface electrically charged at a different potential from that of the mass, and arranged to receive the charged mass. (7.) An apparatus for the purpose described, consisting of a conveying-surface, a source of electrostatic energy arranged relatively thereto for imparting to the mass an electric charge, and a moving repelling-surface electrically charged at an opposite potential from that of the mass, and arranged to receive the charged mass. (8.) An apparatus for the purpose described, consisting of a conveying-surface, a source of electrostatic energy arranged relatively thereto for imparting to the mass an electric charge, a repelling-surface electrically charged at a different potential from that of the mass, and arranged to receive the charged mass, and opposite said repelling-surface an electrically charged surface of opposite potential to that of the repelling-surface. (9.) An apparatus for the purpose described, consisting of a conveying-surface, a source of electrostatic energy arranged relatively thereto for imparting to the mass an electric charge, a repelling-surface electrically charged at a different potential from that of the mass, and arranged to receive the charged mass, and opposite said repelling-surface an inclined surface electrically charged at an opposite potential to that of the repelling-surface. (10.) An apparatus for the purpose above described, comprising a conveying-surface, a source of electrostatic energy arranged relatively thereto for imparting to the mass an electric charge, a repelling-surface electrically charged at a different potential from that of the mass, and arranged to receive the charged mass, and opposite said repelling-surface a series of inclined shutters electrically charged at an opposite potential to that of the repelling-surface.
