    Teschemacher s Improvements in Producing Steam in Engines, ^c. and produce a very large quantity of steam with very little fuel, is founded upon the following principles, that is to say :— The water employed for producing steam is constantly in a running state over inclined planes or shelves which are in contact with the fire that commu¬ nicates the heat to the said inclined planes or shelves. These inclined planes 5 or shelves may be put into different forms or shapes, and the annexed plan, exhibiting three several views or geometrical elevations marked with the several capital letters A, B, and C, will more fully explain the principles upon which the said machine or boiler is founded, by or from which the same can be made, and how the said machine is to be performed and used, viz‘, that part of the plan 10 marked with the capital letter A represents the top of the boiler, into which the Avater is conveyed, and from which the steam issues, and also where a valve may be put to regulate the steam. That part of the plan marked with the capital letter B represents a front view of the said boiler with the different inclined shelves, upon the inside of which the water runs. That part of the plan 15 marked with the capital letter C represents one of the side views of the said boiler. The said plan marked with the said several capital letters A, B, and C, compose or form the Avhole boiler or machine for creating steam, and AA^hich may be made of metallic or any other substances capable of supporting a continual heat of fire. This machine is to be immersed, fixed into, or put upon 20 a common or an air furnace Avith flues and registers constructed in such a manner as Avill draw the flame of the fire the Avhole length of all or any of the said inclined shelves or planes, as the strength or force of the steam is required. That part of the plan above referred to marked with the letters h, represent the inclined shelves or planes Avhich are to be heated by the fire resting 25 against them. The inside of the shelves being constructed as to be steam- tight and to admit a free course of the Avater, the water constantly making its course backwards and forwards from one hot inclined shelf to the other, until it reaches the bottom of the machine, and is then let out at an aperture marked with the letter g. That part of the plan above referred to and marked Avitli the several letters c represents the steam pipe through which the steam passes, and in Avhich are contained four holes or apertures, which are marked with the several letters d, and communicate Avith the inside of the boiler, and 30 by Avhich the steam is let into this pipe from the boiler, and Avhich pipe is perfectly closed at that part of the said machine Avhich is marked Avith the 35 several letters e, and the steam issues at the long end of the pipe which is marked in the said plan Avith the several letters /; from thence it is conveyed by a pipe oi pipes VAuth regulators and A^alves of the same kind as are commonly used for boilers to steam engines; this pipe marked in the said plan above
