| Abstract:
This invention relates to that class of heat motors in which the motive power is obtained by the alternate heating and cooling of the working-fluid in confinement under a higher pressure than that of the atmosphere. Its object is to retain and utilize by means 0f a simple apparatus the heat which is usually carried away and lost in this class of motors by the prevalent systems of condensation, and, in connection with an improved construction of the machine, thereby greatly increase its efficiency.
It consists in a novel organization of the motor, as hereinafter described and claimed, whereby the heater or furnace is located above the cooler or condensing space and the air and vapors necessary to support combustion in the heating apparatus are made to flow over the encircling-walls of the condensing-chamber and thereby absorb and carry back to the furnace or combustion-chamber the heat set free in the condensing process.
Claims:
1. In a non-exhausting thermo-dynamic motor, a working and a displacing piston, both moving in a single extended closed chamber made tight to maintain a static pressure therein exceeding that of the atmosphere, in combination with cranks coupled to said pistons and revolving in one end of the same chamber upon a shaft projecting with an air-tight joint through the wall thereof, substantially in the manner and for the purpose herein set forth.
2. A non-exhausting thermo-dynamic motor comprising a working and a displacing piston, both moving in a single extended closed chamber made tight to maintain a static pressure therein exceeding that of the atmosphere, cranks coupled to said pistons and revolving in one end of the same chamber upon a-shaft projecting with an air-tight joint through the wall thereof, and a body of liquid contained in said chamber to be agitated by the revolution of said cranks, whereby the working fluid in the chamber is charged with vapor from said liquid, substantially-in the manner and for the purpose herein set forth.
3. The combination, in a non-exhausting thermodynamic motor, with its working and its displacing pistons, both moving in the same closed chamber, made tight to maintain a static pressure therein exceeding that of the atmosphere, and with its cranks coupled to said pistons and revolving in an extension of the same chamber upon a shaft projecting with an air-tight joint through the wall thereof, of a body of liquid contained in said chamber and an air-pump coupled to the working-piston and having its inward port covered by said liquid, whereby in the operation 0f the machine a supply of air is introduced and forced through said liquid to produce a discharge of vapor therefrom within said closed chamber, substantially in the manner and for the purpose herein set forth.
4. The combination, in a thermo-dynamic engine, with its heater and its cooler, of an air supply conduit formed in or upon the wall of the cooler to connect with the burner or furnace of the heater, whereby the heat radiated from the former is taken up by the current of air flowing to the latter, substantially in a the manner and for the purpose herein set forth.
5. The combination, with the crank-shaft, in a thermo-dynamic engine, of a working cylinder placed above said shaft, a heater at the upper end of the working-cylinder, and a passage for the supply of air to the heater formed in or upon the wall of the working-cylinder, whereby the working-cylinder is protected from the exhaust-heat escaping from the burner or furnace and is cooled by the current of air flowing thereto, substantially in the manner and for the purpose herein set forth.
v6. A non-exhausting thermo-dynamic motor having the upper or outer end of its working-cylinder encircled by a heating device and the remainder of said cylinder enclosed in a concentric jacket forming an encircling annular conduit through which the heating device is supplied with the air necessary to support combustion therein, whereby the one end of the cylinder is heated and the remainder cooled by the operation of the heating device, substantially in the manner and for the purpose herein set forth.
7. The combination, in anon-exhausting thermo-dynamic motor, with its working and displacing pistons and the connected cylinders in which they move, of an outer jacket of enlarged diameter inclosing said cylinders to form an encircling annular conduit open at both ends, a perforated diaphragm fitted in the upper or outer portion of said annular conduit, and a gas-supply pipe communicating with the lower end of the annular conduit, substantially in the manner and for the purpose herein set forth.
8. The combination, in a non-exhausting thermo-dynamic motor, with its working and displacing pistons and the connected cylinders in which they move, of an outer jacket of enlarged diameter inclosing said cylinders to form an encircling annular conduit open at both ends, a perforated diaphragm fitted in the upper or outer portion of said annular conduit, an annular chamber encircling the lower or inner end of the jacket and communicating by a series of orifices with the enclosed conduit, and a gas-supply pipe fitted to communicate with said chamber, substantially in t-he manner and for the purpose herein set forth.
9. The combination, in a non-exhausting thermo-dynamic motor, with the communicating piston-cylinders and crank-chest inclosing its working parts and made air-tight, of a water-receptacle included within said crank-chest below the working-piston, whereby the air confined within the machine maybe automatically charged with vapor during the operation of the motor, substantially in the manner and for the purpose herein set forth.
l0. The combination, in a non-exhausting thermo-dynamic motor, with the communicating piston-cylinders and crank-chest enclosing its working parts and made air-tight, of a water-receptacle included within said crank-chest below the working-piston, whereby the air combined within the machine may be automatically charged with vapor during the operation of the motor, and a cooling device fitted in said receptacle, whereby its temperature may be lowered, substantially in the manner and for the purpose herein set forth.
11. The combination, with a working-piston, in anon-exhausting thermo-dynamic engine, of the longitudinally-perforated rod ex tending through the piston and secured thereto, the weighted governor-valve playing upon said rod to cover and uncover its ports, and the springs fitted at either end of said valve to control and confine its movement, substantially in the manner and for the purpose herein set forth.
12. The combination, with the closed working-chamber, in a thermodynamic motor, a bearing sleeve projecting with a tight joint through the wall of said chamber, and a shaft projecting outwardly from said chamber through said sleeve and having a shoulder to bear against the inner end thereof, of an annular metallic packing-piece interposed upon the shaft between the shoulder and sleeve and having a beveled or rounded face to fit into a counterpart seat in the sl1oulder,where by an air-tight joint is obtained and preserved at this point, substantially in the manner and for the purpose herein set forth.
13 The combination, in a non-exhausting thermodynamic motor, with its working-piston and the cylinder in which it moves, of the governing pipe V, through which communication is established between the spaces at the opposite ends of the piston, and the valve V', controlling said pipe to open or close it, substantially in the manner and for the purpose herein set forth.
