Claims.—(1.) In combination, a perambulator having hinged floor, axle having two hinged parts pivoted together in the centre, with means for locking said parts in a horizontal position in line or approximately each in a vertical position, substantially as and for the purposes set forth. (2.) In combination, hinged axle-rod as 13 carrying slotted segmental plate as 15, hinged axle-rod as 18 pivotly connected to said plate, and having a pin passing through slot of plate with means of securing same in position, substantially as and for the purposes set forth. (3.) In combination, shafts as 22 pivoted to rail, and having attached thereto slotted plates as 24, and means for forming a secure hold upon the plates, substantially as and for the purposes set forth. (4.) In a collapsible carriage of the kind described, a hinged footboard which collapses correspondingly with the carriage, substantially as set forth. (5.) In combination, cord as 31 connecting hinged step with hinged floor, cord as 34 connecting the two parts of floor, and having a handle as 36, substantially as and for the purposes set forth. (6.) In combination, side-frames of a perambulator, a lateral door or doors, means by which door is hinged to one side of perambulator, and means for securing the other end of such door to frame on that side, substantially as and for the purposes set forth. (7.) In combination, perambulator having hinged back-frame, with means for securing same to side-frame, floor in two parts hinged to side-frames and together in the centre, step in two parts hinged to side-frame and together in the centre, a connecting cord between the said floor and step, a handle, an axle having two hinged parts pivoted together in the centre, and having means for radiating and securing same in position in a horizontal line and in substantially a vertical position, shafts pivoted to the side-rails, and means for holding same in a forward or back position, substantially as set forth.

No. 12280.—4th January, 1900.—UNIVERSAL FUEL COMPANY, of 81, South Clark Street, Chicago, Illinois, United States of America, Manufacturers of Coke (assignees of Joseph Hemingway, of Spearfish, South Dakota, United States of America, Mining Engineer). Improvements in processes of making coke.

Claims.—(1.) The process of coking coal which consists in confining the coal in an oven, firing the coal, and then subjecting the coal to a temperature sufficiently high to cause not only the generation of gases, but also the disintegration of their elements and the conversion of volatile carbons into fixed form and their disposition as constituent appreciable integral additions to the coke product, substantially as described. (2.) The process of coking coal which consists in confining the coal in an oven, firing the coal, and then introducing into the oven above the coal an extraneously heated deoxygenized blast to accelerate the generation and induce circulation or movement in the volatile gases in the oven while the trunnel-hole in the top of the oven is open, thus causing the ingress into the oven of atmospheric air to support combustion and the egress through the same hole of non-combustible or consumed gases, substantially as described. (3.) The process of coking coal which consists in confining the coal in an oven, firing the coal, and then introducing into the oven above the coal an extraneously specially prepared highly heated blast having imparted to it during the act of heating it, as an additional quality, the property of desulphurising coal under heat, substantially as described. (4.) The process of coking coal which consists in confining the coal in an oven, firing the coal, then introducing into the oven above the coal an extraneously heated deoxygenized blast of a temperature before its introduction greater than that usually employed in the coking operation, to increase the heat in the oven above the temperature produced by the combustion therein of the gases generated from the coal, and to accelerate the generation of such gases, and then permitting the deoxygenized blast and that portion of the evolved gases not converted into fixed carbon to escape through an opening at the top of the oven, substantially as described. (5.) The process of coking coal which con,
