[No. 75

America, Mechanical Engineer). Method of and apparatus for reshaping rolled products.

Claims.—(1.) The process of treating traction-rails which consists in reshaping a head thereof into a flange. (2.) The process of treating traction-rails which consists in forming a groove in a horizontal face of a rail-head, flattening this portion of the rail-head and shaping the same into the form of a flange. (3.) The process of treating traction-rails which consists in subjecting a rail to a temperature near to but below that at which the carbon in the rail would be materially affected, and reshaping a head thereof into a flange. (4.) The process of treating traction-rails which consists in subjecting a rail to a temperature near to but below that at which the carbon in the rail would be materially affected, forming a groove in a horizontal face of a rail-head, flattening this portion of the rail-head and shaping the same into the form of a flange. (5.) A machine for treating traction-rails, having three rolls serving to spread the head that is passed between the same into a flange. (6.) In a rolling-mill mechanism for treating traction-rails, the combination with a plurality of sets of rolls, each containing three rolls between which a head of rail may be disposed, these sets of rolls serving to flatten the head and transform the same into a flange. (7.) A machine for treating traction-rails having three rolls serving to spread the head that is passed between the same, one of the rolls being adapted to engage a horizontal face of a rail-head, this roll being provided with a groove-forming periphery to form in the rail-head a groove. (8.) In a rolling-mill mechanism for treating traction-rails, the combination with a plurality of sets of rolls, each containing three rolls between which a head of the rail may be disposed, one roll of each set serving to engage a horizontal face of a rail-head, some of these latter rolls being provided with groove-forming peripheries to form in the rail-head grooves, whereby the rail-head may be readily spread into the form of a flange. (9.) In a rolling-mill mechanism for treating traction-rails, the combination with a plurality of sets of rolls, each containing three rolls between which a head of the rail may be disposed, one roll of each set serving to engage a horizontal face of a rail-head, some of these latter rolls being provided with groove-forming peripheries to form in the rail-head grooves, whereby the rail-head may be readily spread into the form of a flange, while another of the latter rolls is provided with a cylindrical periphery to complete the transformation of the rail-head into a flange. (10.) In a rolling-mill apparatus for transforming the head of a traction-rail into a flange, the combination with a plurality of sets of rolls having peripheral surfaces in correspondence with surfaces of the flange, of additional rolls for successively spreading the head varying degrees until the flange is finally secured. (11.) In a rolling-mill, the combination with a pair of rolls, between which a rail may be grasped and fed, the said rolls being placed in substantial alignment, of a third roll acting upon the rail at right angles to the aforesaid rolls and engaging one side of the rail, an abutment engaging the other side of the rail, the said abutment being in the form of a bar. (12.) In a rolling-mill, the combination with a pair of rolls between which a rail may be grasped and fed, the said rolls being placed in substantial alignment, of a third roll acting upon the rail at right angles to the aforesaid rolls and engaging one side of the rail, an abutment engaging the other side of the rail, the said abutment being in the form of a bar, and means whereby the said bar may be caused to travel as the rail is passed through the rolls.

No. 15329.—26th August, 1902.—WILLIAM BRADY, of 1000½, Hyde Street, San Francisco, California, United States of America, Miner. Rock-drills.

Claims.—(1.) An apparatus for drilling rock and striking blows, consisting of two cylinders in the same line with the pistons fixed to the same piston-rod, and a device for rotably connecting the tool at the front end, said device comprising a clamp, and inclined rods slidable through holes in a ratchet disk which is revolved freely when the tool moves forward, and is held by a pawl so that the inclined rods turn the tool as it is retracted, means for admitting an explosive gas and igniting it alternately at the rear of each piston, and an independent means for returning the pistons and tool after each forward impulse. (2.) A pair of cylinders united in line, a supporting base with guides and means for sliding the cylinders forward upon the guides, pistons in each cylinder fixed to a piston-rod which carries a drill or tool at its front end, means for admitting an explosive gas behind each piston alternately and igniting it to produce a blow of the tool, a returning spring and a crank-shaft, with a pinion engaging a rack attached to the drill-head, said pinion having a pawl which connects it with the crank-shaft to draw the pistons and drill back and a releasing-device to allow the pinion to turn freely when the pistons are driven forward. (3.) An apparatus for striking blows upon drills and the like, consisting of an explosive engine by which the movable parts are impelled and a blow delivered, mechanism by which the parts are returned and the engine charged for an explosion after each forward impulse, and mechanism to advance the apparatus on its base as the work proceeds.

No. 15336.—30th August, 1902.—AMMI FERNALD DAVIS, of San Francisco, California, United States of America, Canvasser (assignee of Mads L. Hansen, of San Francisco aforesaid, Inventor). Detachable heels for boots and shoes.

Claim.—In detachable heels for boots and shoes, a heel-plate attached to the heel portion of the boot or shoe, and adapted to be attached to a corresponding plate fixed to the upper surface of a detachable heel by inclined lugs on one of the plates entering inclined pockets in the other plate, and a spring latch on one of the plates adapted to engage with an opening in the other plate so as to prevent movement of the plates in either direction, substantially as described.

(2.) An improved window-sash fastener consisting of a U-shaped pin or staple, one of the legs of which has a ratchet-tooth or ratchet-teeth thereon adapted to engage the edge of a hole in a retaining and wearing plate, substantially as and for the purposes set forth, and as illustrated. (3.) An improved window-sash fastener consisting of a U-shaped pin or staple, the bend of which is fitted with a filling piece, and the legs of which engage holes in the sash-frame and window-frame respectively, substantially as and for the purposes set forth, and as illustrated.
