COMBUSTION TURBINE.

Application filed June 27, 1927. Serial No. 201,784. I

The present invention relates to combustion turbine and has for its prime Object to provide a highly eflicient structure including a block with a shaft rotatable therein and a rotor keyed thereto, the rotor having vanes incorporatedtherein and means being'provided in the block for exploding gas and causing the exploding gas to impinge and expand against the vanes to set up. rotary motion in the shaft through the rotor.

Another important object of the invention resides in the provision of valve means in the block structure for controlling the intake and exhaust of the gases at the proper timed intervals so as to obtain the maximum power with economy.

A still further very important object of the invention resides in the construction of a combustion turbine'of this nature which is comparatively simple in its construction, compact, has its parts conveniently arranged, and is otherwise well adapted to the purpose for which it is designed.

With the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawin sL Figure 1 is a ongitudinal vertical sectio through a turbine embodying the features of my invention,

Figure 2 is a transverse vertical section taken substantially on the line 2--2 of Figure 1 looking in the direction of thearrows,

Figure 3 is a vertical transverse section taken substantiall I on the line 3-3 'of Figure 1 looking in t e direction of the arrows,

Figure 4 is a vertical transverse section taken substantially on the lines 4-4 of Figure 1 looking in the direction of the arrows,

Figure 5 is a vertical transverse section taken substantially on the line 55 of Figure 1 looking in the direction of the arrows,

Figure 6 is a detail sectional view taken substantially on the line 6-6 of Figure 5,

Figure 7 is an enlarged detail section taken substantially on the lme 7-7 of Figure 4, v

Figule 8 is a transverse vertical section taken substantially on the line' 88 of Figure 1.

Figure 9 is a detail sectional view showing particularly one of the rollers for the valve plates and the mounting thereof.

Referring to the drawings in detail it will I ends of the bearing 7. A water jacketed plate 10 is formed at one end of the bearing and has a rim 11 at the periphery thereof. This nm 11 is provided with a plurality of firing chambers 12 and the plate 10 is provided with passages 13 one leading from each firing chamber 12. The rim 11 is water jacketed as lndlcated at 14. A water jacketed casing 15 is bolted or otherwise secured as at 16 to the rim 11, and houses the rotor R. The wall 16 of the casing is jacketed and provided with openings 17 There are the same number of openings 17 as there are passages 13 and firlng chambers 12. An exhaust manifold 18 has branches 19 leading from the openlugs 17 to an exhaust pipe 20. The shaft 5 is journaled through the wall 16 and the exhaust manifold. This exhaust manifold is jacketed and in communication with the jacketed structure of the wall 16. This exhaust manifold is further provided with a gear casing 21 in which are journaled

shafts

22 and 23. The shaft 22 has thereon inside the casing 21 a pinion 24 meshing with the gear 25 on the end of the shaft 5. A gear 26 is disposed on the end of the shaft 23 in the housing or casing 21 and meshes with the gear 25.

The rim 11 of the .block structure B is provided with a plurality of intake passages 28, one leading into each firing chamber 12 through a valve seat 29. .Poppet valves 30 are seatable on the seat 29 and have stems 30' slidable through bearings 31 formed interiorly of the rim 11. Springs 32 are disposed about the valve stems 30' and normally tatable about" the bearing 7,

anti-friction bearings

37 and 38 being interposed therebetween. This annulus-36 is provided at one end with an internal gear 39 with which meshes a gear 40 on a shaft 41. This shaft 41 is journaled through a head 42 and a bearing 43. The bearing 43 is fixed to the bearing 7. Thehead 42 is disposed about the bearing 7 and is bolted or otherwise secured 'as at 44 to the rim 11. The front end of the shaft 5 has a gear 46 thereon which meshes with the gear 47 on the front end of the shaft 41 and thus when the'shaft 5 is rotating the annulus 36 is rotating in opposite direction thereto. A casing 48 houses the gears 46 and 47 and is attached to the forward end of the bearing 7 by a bolt 49 or in any other suitable manner and to the head 42 by the bolt 44 heretofore referred to. A socket 50 is formed to project from the casing and the shaft 5 has a crank receiving extension 51 so that a crank 52 may be inserted in the socket to engage the extension 51 for cranking the turbine.

Spark plugs 52 are'mounted in the rim 11 to extend into the firing chambers 12 and will be suitably wired with a distributor 53 actuated by the shafts 41. An annular cam member 54 is formed on the annulus 36 and has a single protrusion 55. The rollers 34 ride on the cam 54 and when they engage the protrusion 55, the intake valves 30 are opened as will be clearly apparent. An intake manifold 56 has branches 57 one leading to each intake passage 28 so that combustible gas under pressure may be fed to the explosive chambers 12 when the valves 30 are opened.

The valve plates 59 are slidably mounted across the passages 13 by means of guides 60.

Plates 61 radiate inwardly from the rim 11, one adjacent each valve plate 59 and have openings 62 through which extend bolts 64 adjustably anchored on lugs 65 by means of nuts 66. Rollers 67 are mounted at the ends of the bolts 64 to bear against the valve plates 59. Each valve plate 59 has an extension 69 with a roller 70 journaled on the extremity thereof and extended into a channel 71 of a general annular formation but having an inwardly directed section 72 for opening the exhaust valve plates 59. This groove 70 is formed in a flange 7 3 provided" on the annu- The rotor It comprises a hub 74 keyed to the shaft 5 at 6, a rim 75 and a. plurality of vanes 76 which extend tangentially from the hub 74 to the rim 75 and are curved longitudinally and transversely as will be apparent from an inspection of Figures 5 and 6.

From the above detailed description it is thought that the operation of the turbine may now be followed. The turbine is cranked by hand as explained with the hand crank 52 or by any suitable starting mechanism such as are now commonly in use operating through the shaft 22. As the shaft 5 revolves, referring to

Fi res

2, 4, 5 and 8, in a counterclockwise irection the rotor 36 is revolving in a clockwise direction, and at regular prehaust pipe 20. The shaft 23 may be used as a power shaft for operating the desired mechanism or machine.

It is thou ht that the construction, operation, and a vantages of thisturbine willnow be clearly understood by those skilled in this art without a more detailed description thereof. The present embodiment of the invention has been disclosed indetail merely by way of example since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description. It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described the invention, What I claim as new and desire to secure by Letters Patent is 1. In a combustion turbine, a block comprising a cylindrical bearing and a plate at one end thereof formed with a rim extending about the bearin in spaced relation thereto,
