T0 all 'whom it may concern:
Be it known that l, JOHN ERNEST LEWIS,
Va citizen of the United States of America,
Vwith portable steam plants, especially ,for
quick response in intermittent use.
Referring to the drawings:
Figure l is a perspective view, with parts broken away, of an embodiment of the invention in a motor vehicle propulsion stealn plant;
Fig. 2 is a longitudinal vertical section through the boiler or generator of Fig. 1;
Fig. 3 is an end elevation, from the right of Fig. 2, with parts broken away;
Fig. 4 is a fragmentary view, on an enlarged scale of the liquid level maintenance device for the generator;
Fig. 5 is a fragmentary perspective view looking down on the spark control for igniting the furnace or burner;
VFig. 10 is a section-0n an enlarged scale of the manifolds adjacent the header. Y
The motor vehicle 1 has disposed under the hood 2 the generator. having the refractory heat insulation housing having the base .section 3, the forward upper housing section 4, the reverse bridge-wall 5 and the rear top housing section 6.
The water or liquid supply may be cared for by the steam pump 7 connected by the line 8 through the heat resisting housing with the reserve liquid chamber 9 having a plurality of liquid flow tubes 10 leading 'Y downward therefrom, and then forwardly as the manifold sections 11, in parallel series resting on the housing seats 12, 13. To provide increased heat exchange surface, it is Y preferred to have rise from the manifolds 11, smaller cross section riser tubes 14 ter-v minating in the parallel upper horizontal manifolds 15 extending forwardly into the transverse header 16. The main steam line 17 may extend therefrom out `through the heat resisting duct 18 of the generator housing having the branch Y19 for controllably actuating the pump 7. This duct 18 as a jacket for the steam main 17 may extend to the vehicle propelling motor 20 mounted adjacent the rear axle of the automobile 1. Exhaust Vfrom this motor 2O may be conducted by the line 21. The radiator 22 may serve as a condenser .for exhaust. From the condensed liquid containing supplyv tanks 23, the feed water may pass by the line 211 to the pump 7.
The feed water line 8 to the boiler from the pump 7 has therein the check valve 25 opening toward the boiler or generator, precluding pressure from the boiler creating any back flow toward the pump 7. This line 8 also has therein the needle'valve 26 carried by the sliding yoke 27 actuable by the heat expanded tube28 connected by the Yduct 29 to the chamber 9 at the region of va or suchhifrher tem erature substance entering the tube 28 and retaining such temperature to a much greater degree than the liquid, especially due to latent heat therein, expands the tube 28, causing the needle valve 26 to seat and close the by-pass line 30, normally returning the water from the pump 7 Yto the reserve or supply tank 23. VWith this by-pass closed, the continuously acting pump 7 forces liquid into the line 8, past the check `valve 25 Vinto the reserve chamber 9 to raise the liquid level therein. This feeding of liquid to the boiler continues until the liquid level is raised in the chamber 9 to fill the duct 29 and tube 28. Contraction of the tube 28 then opens the by-pass line 30, in order that the continued action of the pump may not still supply the boiler. Y
Disposed in the chamber 9 isthe float 31 carried by the arm'32 on rock shaft 33 having on its portion protruding from the hous- `ing the arm 34 movable acrossthe scale 35,
of the generator by the lugs 36 to preclude "due to heating in the furnace to rock the' excessive local heating to deterioration action in the generator is the heat conducting hood 37 disposed over the manifolds 15 and header 17 as a shield for the generator against the direct action of the burner or furnace discharge heat source 38. This burner 38 is disposed for providing the' initial heat intensificationA region adjacent the water level region about the great relative heat conducting area ofthe tubes 14. The upper portions of these tubes 14, above the water line, and the manifolds 15 with the communicating header 16 serve as a vaporizing or steam dome for superheating or drying the vapor, due to the heat conducting Vaction of the hood 37. This localizing of the intense heat for practically surface escape to vaporization is a direct asl'iing of the liquid to steam without introducing any dampening or retarding by convection due to gas bubble travel through any overlying liquid region. This means practically instantaneous steaming response.
'The housing about the boiler provides a passage for the boiler enveloping heat flow downward from the burner 38 in a direction opposing the liquid` flow. This heat flow passes under the bridgewall 5, about the down flow tubes 10, and rises to pass the reserve chamber 9, that there may be prelieating. As a heat retaining jacket, the burner fumes envelop the main 17 in its extent to the inotor 20, and for heat economy are used to jacket the cylinders of theV motor 20.
Further use is made of this furnace exhaust by having the fan 39 air blast duct 40 in such duct 18. Adjacent the venturi restriction 41 inthe duct 40 is the fuel supply yduct 42 which may have a float chamber liquid maintained level in the vessel 43. The attened discharge of the burner 38 is proportioned tothe lateral extent of the paralle] manifolds 15. Y
' Throttle lever 44 adjacent the steering wheel 45 may control the supply of steam to the motor 20 by the line 17. 'When the power consumption falls below tliecapacity of the generator or boiler, there may be automatic control for limiting the boiler generation rate, as by rise in pressure acting upon the diaphragm control device 46 for opening Y the switch v47 and stopping the blast fan driving motor 48, as actuated from the generator or storage battery for vehicle night lighting.
Connected to be actuated from an arm adjacent the throttle lever 44 is the switch 49 f or the spark plug V50 disposed Vin a vcentral region for insuring fuel ignitionY in the vapor` ej ectment region.
YDisposed forwardly in this furnace lor burner heat region is the expansion Vbar or tube 51 having the fixed mounting'52 and the movable end 53 operating in bar expansion volume of water, giving a vstability for riar- Y i'owrange of water level fluctuation i'i'i'jthe' tubes 14. Further the general disposalfof the feed water may intermittently readily respond with a considerable safety 'leeway All the ow is against' the lieattravel. The
