(2.) As a means of and for nullifying or minimising the vibratory action or motion in gas fittings and connections injurious to fibrous incandescent mantles used on and in conjunction with the burners thereof, the combination, interposition, and use with gas fittings, burner, and mantle of a piece or short length of rubber or other flexible tubing such as C, forming a section of the gas-supply pipe leading to and feeding the gas to the burner, fitted, applied, and held or sustained in a taut vertical position, in manner and as described and illustrated. (3.) As a means of and for receiving the vibratory action or motion imparted to gas fittings and connections injurious to fibrous incandescent mantles used on and in conjunction with the burners thereof, the connection thereto and use therewith of a wire spring bow formed of a single piece of strong steel or copper wire bent into ringed convolutions such as E, fitted, applied, and sustaining in taut vertical position a rubber or other flexible tube such as C, interposed in and forming a section of the gas-supply pipe leading to and feeding the burner, as described and illustrated. (4.) In a gas-burner and connections for use in conjunction with a fibrous incandescent mantle, the combination and arrangement of the respective parts, such as A, A¹, B, C, D, E, F, G, H, and I, fitted, applied, and operating as and in manner described and as illustrated.

(2.) The combination of a rotary box-form adapted to receive the body portion of the box, retaining-mechanism for holding the end-forming disc in position against said box-form, and a swinging arm in which is mounted said box-form and said retaining-mechanism. (3.) The combination of a box-form adapted to receive the body portion of the box, retaining-mechanism for holding the end-forming disc in position against said box-form, a support for said box-form and said retaining-mechanism, said support being movable to and from a strip-pasting mechanism, and said strip-pasting mechanism. (4.) A box-holder for a box-covering machine comprising the combination of an arm in which is mounted a box-form, said box-form adapted to receive the body portion of the box, and retaining-mechanism mounted on said arm for holding the end-forming disc against said box-form. (5.) The combination of a supporting-frame, a press-roll, a driving-mechanism for rotating said press-roll, a rotary box-form adapted to receive the body portion of the box, a retaining-mechanism for holding the end-forming disc in position against said box-form, mechanism for turning an edge portion of the covering-strip over upon the outside of said end-forming disc, and mechanism for carrying the box-form and disc-retaining mechanism to and from said press-roll, said press-roll driving said box-form by frictional contact and pressing the covering-strip upon the body portion of the box. (6.) The combination of a supporting frame, a driving-mechanism, a press-roll, a box-form adapted to receive the body portion of the box, a retaining-mechanism for holding the end-forming disc in position against said box-form, mechanism for turning an edge portion of the covering-strip over upon the outside of said end-forming disc, and mechanism for bringing said box-form and press-roll together to press the covering-strip upon the box. (7.) The combination of a supporting-frame, a driving-mechanism, a box-form adapted to receive the body portion of the box, a retaining-mechanism for holding the end-forming disc against said box-form, a rotary disc that turns over and presses an edge portion of the covering-strip upon the outside of the end-forming disc to bind said end-forming disc to the body portion of the box, a press-roll that presses the covering-strip upon the body portion of the box, and mechanism for positioning said end-forming disc against the covering-strip between said rotary disc and said press-roll. (8.) A box-holder made up of the combination of a supporting-frame, a swinging arm pivotally mounted in said frame, a rotary box-form mounted on said swinging arm, and adapted to receive the body portion of the box to be covered, a lever fulcrumed on said swinging arm, and retaining-means mounted in said lever for holding the end-forming disc of the box in position against said box-form. (9.) A box-holder made up of the combination of a supporting-frame, a swinging arm pivotally mounted in said frame, a rotary box-form mounted on said swinging arm and adapted to receive the body portion of the box to be covered, a lever fulcrumed on said swinging arm, a stop-screw for limiting the movement of said lever towards said arm, and rollers journalled in said lever to hold the end-forming disc against said box-form.

No. 14055.—26th September, 1901.—MARCUS RUTHENBURG, of Hotel Imperial, Eleventh and Filbert Streets, Philadelphia, Pennsylvania, United States of America, Consulting Engineer. Improvements in methods of and apparatus for agglomerating comminuted ores and concentrates.

Claims.—(1.) The described process, which consists in mixing comminuted ore or concentrate with a fluxing-medium, assembling a mass of the mixture in the path of an electrical current, subjecting said mass to the action of an electrical current until the particles of the mass are fritted together, and removing the product from the action of the electrical current in coherent lumps, substantially as set forth. (2.) The described process, which consists in mixing comminuted ore or concentrate with a reducing-agent, assembling a mass of the mixture in the path of an electrical current, subjecting said mass to the action of an electrical current until the particles of the mass are fritted together, and removing the product from the action of the electrical current in coherent lumps, substantially as set forth. (3.) The described process, which consists in mixing comminuted ore or concentrate with a fluxing-medium and a reducing-agent, assembling a mass of the mixture in the path of an electrical current, subjecting said mass to the action of an electrical current until the particles of the mass are fritted together, and removing the product from the action of the electrical current in coherent lumps, substantially as set forth. (4.) The described process, which consists in assembling a mass of comminuted ore or concentrate in the path of an electrical current, subjecting said mass to the action of an electrical current until the particles of the mass are fritted together, removing the product in coherent lumps from the action of the electrical current to an enclosure, and maintaining the product at a reducing temperature until reduced to the metallic state, substantially as set forth. (5.) The described process, which consists in mixing comminuted ore or concentrate with a reducing-agent, assembling a mass of the mixture in the path of an electrical current, subjecting said mass to the action of an electrical current until the particles of the mass are fritted together, removing the product from the action of the electrical current in coherent lumps, and retaining the product in heated condition until the effects of the reducing-agent are equalised throughout the same, substantially as set forth.
