Description: |
| This was Perry's second gas engine patent. The first being #3,597.
Abstract:
On the 5th day of May, 1844, Letters Patent were granted to me by the United States for an "engine to be operated by the explosive mixtures of inflammable gases or vapors." In this engine, the piston is impelled by means if inflammable gas or gases generated from liquids or solids, and, together with atmospheric air exploded within the cylinder, the expansive force of the gases thus exploded being the impelling agent.. It has been found, however, that the heat thus generated and communicated to the cylinder and to the other parts of the engine is a serious practical difficulty, and the leading object of my present improvements is to remedy this and other serious defects.
My first improvement consists in surrounding the cylinder of the engine with water to carry off the heat generated by the explosion of the gases and keep it at a sufficiently low temperature for the efficient action of the engine, and at the same time, in certain cases, to employ this surrounding water as a water-bath for the retort which generates the inflammable gas when the gas is generated from a liquid or liquids, the heat generated by the combustion of the gases, being sufficient to seep the water at the temperature required or generating the gas, while the water carries off the heat from the cylinder to prevent it from being overheated.
My second improvement consists in lubricating the piston and the inside of the cylinder with water, which not only prevents the wear of the parts, but at the same time aids in preventing these parts from being overheated.
My third improvement consists in' lubricating the piston-rod and preventing it from being overheated by surrounding it with water at or near the stuffing-box.
My fourth improvement consists of a new method of inflaming the gases by platina heated by the heat of inflamed jets of gas and air from the retort acting thereon, the platina being so situated as to communicate, by a valve or valves directly with either end of the cylinder or with the passages through which the mixed gas and atmospheric air pass to either end of the cylinder and my fifth improvement consists in the employment of a receiver containing condensed atmospheric air for starting the engine, in combination with another receiver and with an air-pump, by means of which atmospheric air is forced for, the continued working of the engine, the said air-pump being operated by the engine.
Claims:
Surrounding the cylinder and induction-passages of an engine operated by the explosion of gases with water for the purpose of keeping it at the requisite temperature.
Cooling and lubricating the inside of the cylinder and piston of an engine operated by the explosion of gases by injecting water within the cylinder, whether this be effected. in the manner as herein described or in any other manner producing the same effects, as described.
Cooling and lubricating the piston-rod and stuffing-box of an engine operated by the explosion of gases by injecting water around the piston-rod and within the stuffing-box, substantially as described.
The method of inflaming the explosive mixture in the cylinder or in, the induction-passages by means of heated platina or other metal having like properties, and provided with a valve or~ valves by which the heated surface can be separated from the explosive mixture, substantially as described.
The combination of a receiver of condensed air filled by an auxiliary force, with the receiver, into which air is forced during the action of the engine, as described, for the purpose of starting the engine, as described. |
