INVENTIONS. Joseph Leightham of Lebanon Pa. The invention covers boilers arranged in the furnace with tubes sur rounding the fire chamber above the grate bars and connected by branch pipes with the boilers with a superheater held above the boilers and connected with boilers with other novel features. A sliding door lock has been patented car door fastening comprising a plate with a series of undercut sockets and a slot connecting them with a block having a portion adjustable into any one of the sockets and movable in the connecting slot from one to the other by which the door may be made fast closed or open to any desired degree. A car coupling has been patented by Mr. George J. Ferguson of Greenville Tex. This in vention provides a locking and unlocking device to be placed entirely outside of end of car to allow any mode of attaching drawheads the unlocking device being self-retaining in uncoupled position and permitting operator to uncouple and leave cars uncoupled without their being pulled apart while it is unnecessary to go between the cars for coupling and uncoupling. A tubular hot air furnace has been patented by Mr. Frederick Shriver of Grand Rapids Mich. The shell of the chamber is made of plate iron with the lower part of the vertical section lined with fire brick to form a fire chamber and resting upon a cast iron bed plate the latter supporting a fire grate resting upon a brick foundation with other novel features making a furnace that can be readily cleaned and repaired is easily built and will be effective and durable. A combined steam and hot air furnace has also been patented by the same inventor. It is so constructed that a large amount of water-heating sur face and air-heating surface are exposed to the direct action of the products of combustion and that all the parts of the furnace can be readily cleaned and re paired. AGRICULTURAL INVENTIONS. A hay stacker and loader has been pa Kansas. This invention covers a novel construction and combination
