Patent Number	Date	Title	Name	City	Description
125,166	Apr. 02, 1872	Improvement in Gas Engines	George B. Brayton	Boston, MA	Patented in Canada, patent #2343. Abstract: The invention hereinafter described relates to a means for making practically available, is a motive-power, those compounds which re- milt from the mixture of gases obtained from light hydrocarbons with atmospheric air. It has for a longtime been known that such compounds were capable of developing, upon ignition, an immense degree of force, and various attempts have been made to employ them as motive agents for working machinery. My invention is embodied in a structure which provides, first, for maintaining an accumulation Aa limited quantity of the gaseous compound under considerable but- uniform pressure in the reservoir, the supply to the reservoir being always proportioned to the consumption of the engine, and the gaseous compound mixed only as it is introduced to the reservoir; and, secondly, for introducing a jet of the mixed compound so under pressure, while in the act of changing its volume as the result of ignition, into a cylinder, to act with its expansive force upon a moving piston. Claim: A pumping-engine, for condensing air and gas; a reservoir for containing such agents, either separated or when mixed, and a cylinder and working-piston, provided with suitable automatic valve-gear, operating induction and eduction valves, when such cylinder is furnished with a perforated partition whose office is to maintain a torch to fire the successive charges of gaseous mixture as they are entering the cylinder and prevent the back action of the ignited charge.
2,343	May. 08, 1873	Improvement in Gas Engines	George B. Brayton	Boston, Suffolk County, MA	Patented in the U. S., patent #125,166. Abstract: The invention, hereafter described, relates to a means of making practically available as a motive power, those compounds, which result from the mixture of gases obtained from light hydro-carbons with atmospheric air. It has for a long time been known that such compounds ere capable of developing upon ignition, an immense degree of force and various attempts have been made to employ them as motive agents for working machinery. My invention is imbodied in a structure, which provides first, for maintaining an accumulation of a limited quantity of gaseous components under considerable but uniform pressure in the reservoir, the supply to the reservoir being always proportioned to the consumption of the engine and the gaseous compound mixed only as it is introduced to the reservoir, and secondly, for introducing a jet of mixed compound so under pressure, while in the act of changing its volume as the result of ignition, into a cylinder, to act with its expansive force upon a moving piston. Claim: A pumping engine for condensing air and gas; a reservoir for containing such agents, wither unparted or when mixed and a cylinder and working piston, provided with workable and automatic valve-gear, operating induction and eduction valves, when such cylinder is furnished with a perforated partition whose office is to maintain a torch to fire the successive charges of gaseous mixture as they are entering to cylinder and prevent the back action of the ignited charge.
151,468	Jun. 02, 1874	Gas Engines	George B. Brayton	Boston, Suffolk County, MA	Abstract: in the Letters Patent for improvement in gas - engines granted to me under date of April 2, 1872, No. 125,176, reference is made to the fact that the vapor of naphtha mixed with atmospheric air in proper proportions will form a gaseous compound which, upon being ignited, can be used as a motive power for the engine described in said patent. There exist, however, certain practical difficulties in the way of employing the vapors of light hydrocarbons with the apparatus shown and described in said patent, which it is the object of the present improvement to overcome. My invention consists in a certain means for enabling a given quantum of atmospheric air, as it is passing toward the combustion-chamber of the engine from a reservoir where it has been confined under pressure, to become carbonized by being brought into contact with a liquid hydrocarbon, which is vaporized by the air-current passing over or through it, and such vapor being absorbed by the air a compound results which possesses the constituents of carbon, hydrogen, and oxygen, in proper proportions to furnish, when ignited, the agent of force for the motive power of the engine. Claim: An apparatus for mixing atmospheric air and volatilized hydrocarbons in successive charges as a motive power, when ignited, for a gas-engine, consisting of a reservoir, C, containing atmospheric air under pressure, in combination with a hydrocarbon-chamber and an automatically-actuated valve, which is arranged to intermittently admit compressed air to pass from the reservoir in successive charges into the hydrocarbon-chamber.
190,411	May. 08, 1877	Piston for Air and Gas Engines	George B. Brayton	Exeter, Rockingham County, NH	Abstract: My invention consists in constructing the piston with a hollow chamber, which chamber is in combination with two "hollow piston- rods, so as to provide a means for the continuous circulation of a stream of cold water through the piston and its rods. Claim: The combination, with a piston having an interior chamber, of two separate hollow piston-rods, communicating directly with the chamber of the piston, one of which piston-rods is connected with a water-supply, whereby a continuous stream of water can flow through the piston for cooling the same.
432,114	Jul. 15, 1890	Gas and Air Engine	George B. Brayton	Exeter, Rockingham County, NH	Application renewed 16 Dec 1889. Abstract: One portion of my invention is applicable to and of value in any engine of this general type in which fuel is burned at only one side of the piston, provided that the opposite end of the cylinder be so closed that a partial vacuum may be induced therein on the side of the piston opposite to that at which the firing occurs, and also provided that said fuel be burned at strokes of the piston which intervene with strokes during which no burning occurs, and still further provided that atmospheric pressure can be permitted to act upon the firing side of the piston during those strokes thereof which alternate with 35 the firing strokes. Claim: The combination, substantially as hereinbefore described, of a cylinder closed at both ends, a piston, appliances for supplying to fuel to said cylinder and igniting it at one side of said piston, a condenser communicating with both ends of the cylinder, a valved air-inlet for supplying air to the firing end of said cylinder, a valved exhaust-port at said t5 firing end of the cylinder and between the latter and said condenser, positively-actuated valve mechanism by which said air-inlet port is opened during portions of the alternating non-firing forward strokes of the piston, and also for intermittingly opening said exhaust- port, and an auxiliary exhaust-port, which is located at the opposite or non-firing end of the cylinder guarded by a valve so weighted as to freely open to pressure within the condenser and within the communicating non-firing end of the cylinder.
432,260	Jul. 15, 1890	Hydrocarbon Engine	George B. Brayton	Boston, Suffolk County, MA	Patented in Great Britain, patent #189011062. AbstractThis invention relates to that class of engines which derive their power from the expansion produced by the combustion of sprayed or atomized hydro-carbon in the cylinder. The objects of this invention are to insure an abundant supply of air to support combustion in the cylinder with the least expenditure of power; also to provide means whereby the liquid fuel is delivered into the combustion chamber in a finely divided state most favorable to quick combustion, also to provide novel means for regulating the speed of the engine by automatically varying the amount of liquid fuel which is fed to the combustion chamber; also to construct an incandescent burner which will instantly ignite the combustible mixture which is injected into the combustion chamber; also to improve the engine in various other respects. Claim: The combination with a cylinder provided with a valve guarded air inlet, a piston which moves forward while said inlet is open, and then rearward after it is closed for compressing air thus supplied to the cylinder, of a spraying device within the cylinder and a pump which forces a charge of liquid fuel through and from said spraying device into said cylinder in a finely divided condition fit for immediate combustion in the presence of the compressed air substantially as set forth.
