Specification of Letters Patent. Patented Sept, 30, 1919.
Application filed August 16, 1917. Serial No. 186,463.
Ta aZZ whom it may concern:
Be it known that I, ARTHUR A. Fnmsrnn'r, a filtizen of the United States, residing at Chicago, in the county of Cook and State a of Illinois, have invented certain new and useful Improvements in Humidifying Attachments for Gas-Engines, of which the following is a specification.
his invention relates in general to as to engines and more particularly to humidi the engine is cold, a rich mixture is required and, consequently, it is not necessary or desirable to introduce auxlliary air into the manifold until the engine has speeded up.
My present invention is designed with the end in view of automatically controlling the admission of moistened air to the intake manifold from the speed of the engine, so that when the engine is being started. the humidifying apparatus will be rendered inoperative, but when the engine has accelerated up to a predetermined speed the hu- \midifying apparatus will be automatically thrown into operation. T
In order that my invention may be readily understood I have illustrated one preferrcd embodiment thereof on the accompanying drawings which should be considered in connection with the following description. Referring to the drawings,-
Figure 1 is a side elevation of a gas enginc equipped with my invention, the air inlet and governor being shown in section; and
Fig. 2 is an enlarged sectional view through the air controlling mechanism.
' On the drawings reference character 3 indicates generally a gas engine which may be of any preferred type or construction, the cylinders being supphed with an explosive mixture through the intake manifold 4 from the carbureter 5 in the usual manner.
Upon a bracket 6 securely supported from the exhaust manifold 7 or any other convenient location there is carried a liquid receptacle 8 which, in the present instance, is shown as being made of glass and threaded at its upper end for threaded engagement into a cap 9 permanently secured to the horizontal portion 11 of the bracket 6; An embracing strap 12, also carried by the bracket 6, surrounds the receptacle, and when the thumhscrew 13 is tightened up the receptacle is snugly embraced by the strap and held in position. For filling the receptacle the strap 12 is loosened by unscrewing the thumbscrew 13, whereupon the receptacle may be un threaded from the cap 9 and lowered out of engagement with the strap.
The top of the receptacle is connected with the intake manifold l by means of a tube or pipe 14: communicating with the interior of the receptacle through a coupling 15 and with the interior of the manifold through a coupling 16 tapped into the manifold. The receptacle is adapted to contain water or other" preferred liquid, and air is supplied to the receptacle through a pipe 17 projected through the top 9 and secured thereto by a coupling 18 and having a downward exten sion 19 which projects into the receptacle to a point near the -bottom thereof where it is provided with air discharge openings 21. When suction is applied to the receptacle from the engine cylinders through the pipe 1 1 air will be drawn into the receptacle through the pipel? and delivered by the tube- 19 through the openings 21 into the receptacle beneath the liquid level therein, and the air so delivered will bubble up through the liquid and be drawn off from the receptacle through the pipe 14 into the cylinders.
Compensating air holes 22 are preferably provided in the pipe 19 above the liquid vided mechanism which will now be de-- scribed. Reference character 23 indicates a shaft disposed parallel with and beside the engine, this shaft in some makes of engine being the pump shaft and in others the shaft which drives the starting generator. In the disclosure selected for purposes of illustration the shaft 23 is shown as the drive shaft for the starting generator 24 and this shaft may be driven from the crank shaft of the engine by gcars, a belt, or other well known driving connections. Adjacent the generator I have mounted upon the shaft 23 a hollow casting 25 which is suitably anchored to the engine base or a stationary partpf the generator frame so that this casting is rigidly mounted. The intake end of the air supply pipe 17 is connectedto this hollow casting by means of a coupling 26. The
casting except for its communication with the pipe 17 is entirely closed except for a narrow slot 27 formed in the outer face of the casting and extending concentrically with the shaft 23. This slot communicates on the outsidewith a V-shaped groove 28 formedin the face of the casting.
Upon the shaft 23 there is mounted a centrifugal governor consisting of a head 29 secured to the shaft 23 by a; setscrew 31 so as to be adjustable longitudinally of the shaft, and a head 32 provided on its outer face with a V-shaped annular rib 33 adapted to fit in the annular groove 28 and completely closethe slot 27. The two heads are connected by a plurality of leaf spring members .34, each equipped with a weight 35. Normally the airinlet slot to the interior of the hollow casting 25 is closed by the rib 33 of the governor. When the engine is started the shaft 33 will slowly revolve carrying with it the centrifugal governor, and the rib 33 will turn in the groove 28. As the engine accelerates the centrifugal action ofv the weights35 will withdraw the head 32 from the casting 25, thereby withdrawing the rib 33 from the groove 28 so as to open the air intake slot 27 and set the humidifying apparatus in operation.- The speed at which the rib 33 will be withdrawn so as toadmit air to the receptacle through the pipe 17 may be regulated by adjusting the head 29 longitudinally on the shaft 23 so as to increase or decrease the force with which the rib will be held in its groove. In Fig. 1 the device is shown as closing the air inlet slot while in Fig. 2 the device is shown in fulllines as withdrawn so as to admit air when the engine is running at high speed,
and in dotted lines it is shown as closed similarly to F igu 1.
It is believed that from the foregoing it will be understood that I have provided a humidifying apparatus and a control therefor by which the apparatus will be rendered inoperative until the engine has reached a predetermined speed so as to permit the engine to start on a rich mixture, and after this predetermined speed has been reached the apparatus will automatically operate to admit air to the humidifying receptacle from which, after being moistened, it is drawn into the engine cylinder to increase the efficiency of the engine.
Obviously the structural details illustrated and described are capable of considerable variation and modification within the scope of the invention as set forth in the following claims: i
v I claim:
1. The combination with a' gas engine in cluding cylinders, a manifold and a carbureter, of a receptacle adapted to contain liquid, means for introducing air into the said receptacle below the liquid level therein, a connection between the receptacle above the liquid level and said engine manifold through which moist air is delivered from the receptacle to the manifold, and means the liquid'level therein, an inlet chamber.
connected to the intake end of said pipe and provided with an inlet port, and a governor controlled solely by the speed of said engine for regulating the admission of air through said ort. 3. he combination with a gas engine lncluding cylinders, an intake manifold and a carbureter connected thereto, of a receptacle adapted to contain liquid, a pipe for conducting moist air from said receptacle to said intake manifold above the carbureter, a pipe projecting through said receptacle below the liquid level therein through which air is delivered to said receptacle below the level of the liquid, a centrifugal governor controlled solely by the speed of the engine, and means actuated by said governor for regulating the admission of air through said pipe to said receptacle.
4. The coinbination of a gas engine inan intake manifold and a;
adapted to confor supplying air to said the liquid level therein, an
inlet chamber connected to the intake end of said pipe and provided with an annular inletport, a centrifugal governor controlled solely by the speed of the engine,
