Another object of my invention is to provide a new and improved self-operated heater of the internal combustion type which is smoother in operation than the heaters heretofore known.
Another object of my invention is to provide a new and improved self-operated heater of the internal combustion type which automatically controls its own rate of operation, and requires no accurate timing mechanism.
Other objects and advantages will become apparent as the description proceeds.
In the drawings:

Fig. 2 is a vertical sectional view of my invention taken at right angles to the view of Fig, 1, plane of the line 2-2 of Fig. 3 is a partial vertical irregular line 3-3 of Fig. 2;
Fig. 4 is a partial'horizontal section taken on the line 4-4 of Fig. 2;
Fig. 5 is a partial irregular section taken on the line 5-5 of Fig. 2;
Fig. 6 ma side view of a portion of the rotor, and is taken on the line 6-6 of Fig. 7;
Fig. '7 is a top view of the rotor structure shown in Fig. 6;
Fig. 8 is a sectional view taken on the line 8-8 of Fig. 1, with the addition of a diagramsection taken on the matic representation of the electrical connections;
Fig. 9 is a vertical section taken on the irregular line 9-9 of Fig. 1, and
Fig. 10 is a perspective view of a portion of the rotor buckets indicating the helical path travelled by the exhaust gases.
Referring particularly to Figs. 1 and 3,. it will be seen that I have illustrated my invention as being embodied in a form comprising a base 20 formed of a pair of castings 22 and 24 secured to each other by bolts 26, or in any other suitable manner. The castings 22 and 24 have pedestals 28 and 30, respectively, and these pedestals support ball bearings 32 and 34, respectively. A hollow shaft 36 is journaledin the bearing 32 and is attached by studs 38 to the side plate 40 of a rotary heat exchanger indicated" generally by reference character 42. This rotor includes a second sldeplate 44 secured to one end of a solid shaft 46 journaled in the ball bearing 34.
The side plates 40 and 44 of the rotor consti tute headers to which are aflixed the ends of ventilating air tubes 48, which are spaced slightly from each other to provide openings therebetween for the flow of hot gases in a manner hereinafter described. The multiplicity of ventilating air tubes 48 forms a ring surrounding a central chamber duction passage 52 provided ,by the hollow shaft 36. The rims of the rotor plates 40 and 44 are attached to a ring 54 by means of screws 56.
A plate 58 is attached to the upper end of pedestal 28 and supports a carburetor 60 having a float bowl 62 supplied with fuel from any suitable source. This float bowl communicates with a jet 64 located in the carburetor air inlet 66, and the amount of fuel delivered by the jet 64 may be manually-regulated by a needle 'valve 68. A screen 10 attached to the carburetor air inlet prevents dirt or other impurities from en tering this inlet.
A valve. 12 is urged towards its seat 14 by a light spring 16. This valve controls communication between the jet .64 and inlet 66, and the passage 18 communicating with the passage 52 in the tubular shaft 36; in other words, this valve controls the communication between the carburetor and the interior of the rotor. This valve is open to admit a combustible mixture of fuel and air to the rotor by suction created by rotation of this otor either in the normal operation of the heater or by manually rotating the rotor to start I the heater.

preciable space I I8 existing between the opposing ring 54,
locate the rotor with minute center of the stator, and the permissible tolerattached to around this ring, as clearly shown in Fig. 2. Each nozzle 80 is located at one-side of a small reversing pocket 82 formed in the-ring 54. This ring is also provided with a plurality of larger reverisng pockets 84 arranged in four series, each series having one end adjacent a nozzle 60, and other end of the series communicates with a lateral outlet 06, best shown in Fig. 5.
Each of the pockets 82 has a curved or reversing wall 88 located at an angle with respect to the axis of the ring 54. Each of the larger reversing pockets 84 is alsoprovided with a curved wall or reversing surface 00, likewise located at an angle with respect to the axis of the nozzle ring 54. The pockets 82 are separated from the. and the pockets 04 are separated from each other by similar ofiset walls 94.
tached thereto The nozzle ring 54 is located inside of a stator ring 96containing buckets 08 having curved reversing walls I00 and separated by lips I02. These reversing buckets are arranged tangen- Fig. 2, but lie in planes parallel to the axis of the stator ring 66. The lips I02 are preferably provided with semi-cir- 04, best shown in Figs. 3 and 4. The stator ring 96 is securedby screws I06 to the sheet metal sections I08 and nular housing indicated generally by reference character II2 which is secured to the base 20 by bolts 26, as clearly shown in Fig. 1. Portions of this housing remote from the base 20 are secured together by bolts H4, and a suitable sealing gasket H6 is preferably clamped between adjacent edges of the sections I08 and III) to prevent e smy invention liesin the fact that for the nozzle ring 54 of the rotor and'the stator ring 96 to fit closely to- Fig. 4 there is clearly shown an ap- A feature of the stator ring 96 and rotor or rotor and the presence ofthis space does not impair the eiiiciency of my heater. Because of the presence of this space, it is not necessary to precision at the exact surfaces of ance materially reduces the cost of and assembly.
The combustible mixture drawn into the interior of the rotor is ignited by a pair of spark plugs I20 and I22 screwed into suitable bushings the rotor side plate 44. These spark plugs are supplied with current by a generator indicated generally by reference character I24. and shown most clearly in Figs. 1 and 8. This generator includes an outer ring I26 having arms I21 secured to the rotor sideplate-44 byscrews manufacture -I28, or inany other suitable manner. This ring I26 has inwardly-projecting iron cores I30 surrounded by wire coils I32. In the particular embodiment shown, the ring I26-'supports four coils I32, although any other suitable number may be provided as desired. I
The four coils I32 are connected in series by wires I34, I36 and I38. Each of the and coils "of this series is connected to a terminal I40 insulated from the ring I26 by an Insulating block I42. One terminal I40 is connected by a wire I44 to the spark plug I20, and the other terminal I40 is connected by a wire I46 to the spark plug I22. These spark plugs are in electrical communication with each other through the ring III) of an an-' blower wheel I64 enters a tapered 0 tached thereto by a I90 so that rotation of the drum I68 causes ro- I do ly to start the heater.
6 needle valve of the I52 secured by screws I54 to the upper end of the pedestal 30, and, a semi-circular cover I56 atby bolts I58. The armature I48 is illustrated as having four poles, but any number of poles may be provided, it being desirable, however, to provide as many poles for the armature as there are coils I32.
The exhaust gases discharged from the reversing chambers through the lateral outlets 86' pass into a tapered annular exhaust passage I60 communicating with an exhaust pipe I62 through which the to atmosphere. The exhaust passage I60 has portions on both sides of the nozzle ring 54 and stationary ring 96, and also a portion surrounding the latter ring. This arrangement permits any exhaust gases which flow in either direction through the space II8 between these rings to enter the exhaust passage and be discharged through the exhaust pipe I62. I
The wheel I64 of a blower I66 is attached to the rotary heat exchanger and rotates therewith. This wheel is enclosed in a sheet metal casing I68 (see Fifs. 1 and 9) composed of two sections I10 and I12 clamped together by bolts I14 and withan intervening washer I16 to prevent escape of air the'rebetween. The section I10 (See Fig. 3) is in the form of a ring secured by screws I'IB to the section IIO of the housing II2.v A guide ring I00 is attached by screws to the rotor side plate 40 and serves to direct rior of the blower wheel I64 heated air leaving the right-hand ends of the tubes 48 of the rotor.

The solid shaft 46 has a drum I88 (Fig. 3) atstud I90 which is accessible through an opening whereby this drum may removed from the end of has a keyway I94 receiving be'readily applied to or the end of the stud tatlon of this shaft and the several assemblies attached thereto. This drum is used for starting purposes and a rope may be wrappedabout this drum and the free end of the rope pulled strong- It will be understood, however, that any other suitable starting mechanism may be used in lieu of this drum .and the pull-rope.
When it is desired to start the heater, the carburetor is unscrewed to from the carburetor float bowl A rope is wrapped about the pull exerted thereon to permit fuel to flow 62 to the jet 64. drum I80 and a strong rotate'the axle 46 and parts connected thereto.
Rotation of this axle rotates the rotary heat "and induces a exchanger 42, the generator ring I26 with its coils I32, and the blower wheel I64. Rotation of the heat exchanger creates a suction in the interior thereof, which raises carburetor air valve flow of. air through the carexhaust gases are discharged into the inte- I92 provided in the drum the shaft.

, buretor and into the interior of the heat exchanger. This air mixes with fuel supplied by the Jet 64 to form a combustible mixture which is ignited by the spark plugs I20 and I22 as soon as this mixture completely fills the interior of the rotary heat exchanger.
The resulting explosion closes carburetor value I2 and creates a. pressure which forces the burned gases through the nozzles 80 in the form of jets of burned gases. These jets or streams of burned gases enter the pockets 98 of the stator ring 96 creating a reaction which tends to rotate the heat exchanger. The pockets 98 reverse the flow of the burned gases and cause the streams of these gases to enter reversing chambers 84 which are adjacent the nozzles 80011 the rotor. Impingement of the streams of burned gases upon the curved walls of the reversing chambers 84 exerts an additional force tending to rotate the heat exchanger. The reversing chambers 84'reverse the streams of burned gases and re-direct them into succeeding pockets or reversing chambers in the stator ring .96. This is repeated until the burned gases flow through the outlets 86 into the discharge manifold or passage I60.
Fig. represents somewhat diagrammatically the helix-like fiow of the burned gases leaving the nozzles and passing successively through alternate reversing chambers orpockets formed in the stator ring 96 and rotor ring 54. Each time a gas stream impinges upon the stator ring a reaction ls created whichtends to rotate the heat exchanger, and each time a stream impinges upon the rotor ring 54 of this heat exchanger an additional force is created tending to cause rotation The repeated 'reversals of the gas streams create repeated impingements which utilize the full energy of the streams to create maximum turning effort on the rotary heat ex changer.
After the pressure created in the interior of the heat exchanger by an explosion has been dissipated by a flow of burned gases through the nozzles in the manner heretofore described, continued rotation of the heat exchanger creates a suction therein which draws a fresh charge of combustible mixture into the interior of the rotor. As soon as this fresh mixture reaches the spark plugs I20 and I22, it likewise is ignited, and the cycle of operation is repeated.
Where the alternator which supplies these spark plugs is provided with a multiplicity of coils, these spark plugs create a spark several imes for each rotation of the heat exchanger, Whereas, successive explosions occur at longer intervals such as, for example, every two complete rotations. It is advantageous-to have frequent sparking at the spark plugs to eliminate the need for any close timing between the creation of these sparks and the introduction of a fresh charge of combustible mixture into the interior of the heat exchanger.
These successive explosions in the interior of the rotor or rotary heat exchanger give on heat, and a part of this heat is absorbed by the tubes 48 which transmit this heat to the air drawn through these tubes by the rotation of the blower wheel I64. This blower wheel is attached to the rotary heat exchanger by an annular attaching plate I80 and rotates therewith. The centrifugal blower discharges the heated air into a pipe I 86 which may lead to any point of application for this air.
My new and-improved self-operating heater is particularly adapted for use around airports to supply hot airfor heating aircraft engines, and other similar purposes. A particular advantage of my invention in this regard lies in that fact that it requires no separate internal combustion 5 engine for its operation, and thuseliminates the service dimculties which are commonly encountered with small engines of this kind. The several parts of my heater are of simple construction and subjected to littlewear, so that my heat- 10 er can operate almost indefinitely with little or no attention.
While I have described my invention as being particularly adapted for use around airports, it is not limited .to such use, =but-is capable of general application. It is also to be understood that my invention is not limited to the particular details shown and described, but may assume numerous other forms, and that my invention includes all modifications, variations and equivalents coming within the scope of the following claims.
