Definitions

  • My invention concerns producers of inert gases. Some features of my improvements apply to producers of this kind in general; in other respects my invention concerns producers of inert gases which involve the use of internal combustion engines. The exhaust gases from such engines are frequently used to produce nonexplosive atmospheres above and around readily burnable substances. To assure the quality of the inert gas for such a purpose, its oxygen contents must not exceed a certain maximum, so that the inert gas cannot sustain combustion of an oxidizable gas, when mixed therewith.
  • the housing 1a of the engine is provided with cooling chambers 1b adjoining the combustion chamber 1c as well as the pump chamber 1d.
  • the crank shaft is connected by gearing 17' to the cam shaft 12'.
  • Intake valve 1h is supplied with the mixture of explosive gas through pipe lu which is connected to a suitable carburetor (not shown);
  • Exhaust valve 110 connects through pipe 112, the exhaust manifold to the "scrubber 1w, a tank which serves to suitably wash, clean and filter so the exhaust gases.
  • the upper end of the scrubber connects, by means of pipe 13 to the intake. valve 1m in the pump chamber.
  • Valve 11! functions unidirectionally, a spring seated behind the valve stem keeping the valve normally closed. 35 The valve in opens, when the drop of pressure between the gas in chamber 1d and the gas in pipe 5a is sufficiently large to counteract the tension of the spring in the head of valve In.
  • a fly-wheel 1s of sufficient weight to 5 carry the engine subsequent to an explosion cycle through the remaining three cycles as well as to perform the pumping work in chamber 111 during all four of these cycles.
  • the spur pinion 2a of the starting motor 21 meshes into the spur it on fly-wheel 1s.
  • the spur pinion 2a is adapted to be shifted in.
  • shifting means for the pinion 2a are indicated by a shift lever 2p the free end of which is operatively coupled to the hub on pinion 2a; the shift lever is normally tensioned by a spring 2q in a counter-clockwise direction; in that-position of the lever the pinion 2a is disengaged from the spur gear.
  • a polepiece, mounted on said lever, faces an electromagnet 21', so that energization of said electromagnet will swing the lever to the right.
  • the crank shaft 1c of the engine carries 0 its end a pulley 20 which by means of a belt 2d drives a governor 2e.
  • the crank shaft and the shaft of the governor extending at right angles to each other the belt 20 is of course twisted through degrees to connect the respective pulleys.
  • Upon belt 2d rests an idler pulley 2f near the pulley 2c.
  • Said idler pulley is mounted on the free end of lever 2g which is rotatably pivoted onto bracket 2h.
  • Lever 2g carries a mercury switch 21' which is disposed at such an angle that the swinging downward of lever 2g, when the belt 2d breaks and the idler 2! thereby loses its support, will interrupt the electric contact made in said mercury switch thereby operating the circuit 27'.
  • lever 2k is rotatably pivoted onto bracket 2h, its free end 2m resting on top of the governor 2e.
  • the mercury switch 2n is also electrically connected into circuit 27 and it is mounted on lever 27c at such an angle that the contact in said switch, which is normally closed, is opened, when the governor 2e is driven by the pulley from the engine at such a speed that the free end 2m of lever 21c drops, together with the top of the governor, for a specific distance.
  • the three cables 3a supply electric power from a suitable source of power. They lead to a circuit breaker 3b the control relays 3c of which are suitably connected to a remote point by wires 3d, from where the supply of power to the gas producing apparatus is to be turned on or off.
  • the power supply connects to a second circuit breaker 3e which controls the motor 21) by'means of the conductors 3k, 3m and 3n.
  • the electromagnet 21' is connected across the two latter conductors 3m and 3n.
  • the circuit breaker 3e is controlled by circuit closing relays 3
  • the current required to operate these relays is tapped from one branch of the main power supply at a point between the two. circuit breakers; the wires 39 and 3h indicate part of saidrelay circuit, the wire 3h connecting to the mercury switches 21' and 212. from which the circuit is carried back by the wire 27'.
  • the dial is slidably mounted the contactor 4d serving as a contact which may be set at the point of minimum pressure desired in the storage tank.
  • the pointer 40 is provided on its end with an electric brush member which contacts with con- V tactor 4dlwhen a minimum pressure is reached and the circuit 4a, 4b, is closed thereby.
  • maximum pressure contactor 4mr is similar to the contactor 4d and is also adjustable along the arc of the dialAk.
  • the pointer 40 contacts with said maximum pressurecontactor 4m, electrical contact is established between the circuit 4a and the conductor 4n which leads to the solenoid 4p; solenoid 4p is connected by the conductor 41' to 4w, one of the legs of the source of current. Excitation of solenoid 4p will lift the contact member 4s from its position of rest shown, and will short-circuit the magneto circuit 1q, to which it is connected by a wire 4t, by means of a ground connection 4a to the housing 1a of the engine.
  • the pipe 5a through which the gas is expelled from the pump chamber 142 connects to a T 51), one branch of which connects to a solenoid-operated normally-open valve 56: and from there through opening 511 to the air, whereas the other branch of the T connects to a normally closed solenoid-operated valve 5e which connects to the pressure tank 4g.
  • a pipe connection 5h connects to the CO2 indicator 5i.
  • Said CO2 indicator is of Orsat type or operated on any other principle used in such indicators by those acquainted with the art of testing flue gases.
  • the indicator is operated by a motor 57' which is connected to the main source of power through the circuit breaker 3b and therefore the indicator functions continuously while said remote control circuit breaker 3b is closed.
  • a scale 5k is provided in the CO2 indicator on which the CO: contents of the inert gases may be observed.
  • An exemplary scale ranging from zero to- 15% is indicated.
  • On the scale 5k is slidably mounted a contactor 5m which may be set so as to establish at any point of the scale an electric contact with the .pointer 511.; that pointer indicates on the scale the CO2 contents of the gas.
  • Suitable means for establishing a contact between said pointer and contact 5m are provided onthe end of pointer 51:. so that at and above a certain percentage of CO2 indicated contact is established closing a circuit 510.
  • Said circuit is supplied with power from one leg. of the main circuit and it includes a solenoid 5a which operates a contactor 51'.
  • the contactor 5r closes a circuit 5s which is supplied with power from onebranch of the main circuit and it in-- cludes the two solenoids 5t and 5a. which operate the normally open valve 50 and the normally closed valve 5e, respectively.
  • the stems Em and 5111 of the two valves are normally pressed downward by thesprings 5y, the flux'set up'by the solenoid 5t and 5a counter-acting these two springs.
  • the valve Prior to my invention the valve in represented substantially the only control used in connection with gas producers of this kind.
  • the exhaust gas ceased to operate the valve In and eventually the exhaust gases thus retained in the engine and in tank 1w prevented the entrance upon the explosion chamber of additional unburned gases, the gas in the cylinder head refused to ignite and thus the engine eventually came to a stop.
  • I retain the valve In and although by corresponding function the engine would eventually be stopped when a high pressure has been built up on the exhaust end, I'
  • contactor 4m is set upon the dial 4k so that its upper side aligns with the maximum pressure desired, as indicated on the scale of said dial 4k in the drawing.
  • the contactor 4m has thus been set in the drawing to register with the 90 pound mark on the scale.
  • the pointer 40 will contact with the contactor 4111. when it registers 90 pounds and a current will thus be set up, at and above said pressure, in the circuit 4a, 412, 41', 4111'; the relay 4p in said circuit is excited and the contactor 4s will be caused to close the circuit 4t, 4u. Closing of circuit 4t, 4u short-circuits the circuit lq which serves to supply current from the magneto 1;) to the spark plug 11' and the ignition thus is interrupted.
  • Circuit breaker 3b in turn is controlled by the relay circult 3d.
  • This circuit includes the relays 30 which control the closing of the circuit breaker 3b.
  • the circuit 3d leads to a remote point from where the operation of the gas producer is to be stopped or started, a suitable switch being inclu ed at that point in the circuit 3d. From the main circuit breaker 3b the current leads to the circuit breaker 3e which controls the motor 2?). Circuit breaker 3c is automatically controlled by the relays 3], The closing of switch 3b will however start the starting motor 217 only in case the switch 3c is closed; and the closing of switch Be on the other hand depends on whether the circuit, which includes the relays 3 is closed.
  • Three switches are included in the circuit of the relays 3). These three switches or contactors are the mercury switch 2%, the mercury switch 212 and the low pressure contacting means on the pressure gage 4e.
  • Mercury switch 22' is normally closed when the twisted belt 2d properly extends between the driving pulley 20 on the end of the crank shaft and the governor 2e. This switch is therefore open only in case said belt has been removed from the machine or is broken so as not to support the idler pulley 2).
  • the mercury switch 212 is closed when the engine is not running. When the engine reaches a certain speed, the rotation of the governor allows lever 2m resting on top of said governor to drop and the contact in mercury switch 211 is interrupted.
  • the circuit of relays 3] When the engine is 110 operating at its normal speed the circuit of relays 3] will therefore be open at the point of the mercury switch 2n.
  • the circuit of the relays 3 When the engine is at rest, the circuit of the relays 3 is closed at the point of the mercury switches, and the relays will be energized when the main switch 3b is closed and when the pointer 40 contacts with the contactor 4d on the pressure gage 4e.
  • the contactor 4d has been set on the dial 4k of the pressure gage so that the pointer contacts with 120 the contactor when any pressure below 50 pounds is registered.
  • the start ing motor of the engine cannot be started. But the starting motor 222 will be operated-when the engine is not in operation and when the pressure in the storage tank 4g is at any point below 50 pounds.
  • the relay 2r is under current when the switch 3e is closed. That means 130 that the pinion 2a is pulled into engagement with the. gear 1t whenever the starting motor 2b is,in operation. After the starting motor has started the operation of the internal combustion engine, so that said engine operates as a prime mover, 135 the mercury switch 2n is opened by means of the governor, the switch 3e is thereby opened and the starting motor comes to a stop and the driving pinion 2a is withdrawn from engagement with pipe 5h to the C0: indicator St.
  • the CO: indicator is continuously in operation, the operating motor 59', forming part thereof, being supplied.
  • a dial is shown as part of the indicator which is, as an example, provided with a scale indicating C02 contents within the range from 0% to 15%, the pointer 5n indicating exemplarily the percentage of C02 contained in the inert gas as 6%, and the contactor 5m being set so as to bring about a contact between the pointer 5n and said contactor 5m at about 10% and above said percentage of CO2.
  • the indicator 5n is in the position shown, or registers any other percentage of CO2 contents below 10%, the circuit 5p is open.
  • the solenoid 511 is there-' fore not energized and the circuit 56 is also open. This means that under those circumstances the solenoid valve 5c is open and the solenoid Se is closed, which is the position in which these two valves are shown in the drawing. Under those circumstances, i. e., when the inert gas delivered from the engine contains less than 10% of CO2,-
  • valve 50 will be closed and the by-passing of the gas to the air is thereby interrupted, and valve 5e is opened, the inert gases being delivered to the storage tank 4g. If at any time thereafter the CO2 contents of the gas again drop below 10%, the percentage at which the contactor 5m is exemplarily set on the scale of the indicator 5i, the valves 50 and 5e again return to the position shown in the drawing, the inert gas of in? ferior quality being by-passed into the air. Therefore no gas of an inferior quality is even fed to the storage tank and the quality of gas stored in the storage tank may be kept up to any desired standard by a corresponding setting of 5m 'on scale 5k.
  • the two valves 50 and 5e may be combined into a single three way valve which by means of electrical relays is connected, either to the air or to the storage tank 4g, according to the inferior or superior quality of the inert gases delivered from the engine.
  • the electrical means shown may of course be reduced to a single circuit when the contacting means 5m, 5n are rugged enough to carry the full current required for the operation of the valves.
  • the operative connection between the CO2 indicator and the valve have to be brought about by electrical means but may be made by any other means known to the art.
  • valves selectively controlling the discharge into said storage means or into said branch outlet-and a device operated by said CO2 indicator at the point of registry of a desirable percentage of CO2 and operatively connected to-said valves, so that only gases which contain the said desirable percentage of C02 and a higher percentage thereof are discharged into said storage means.
