The being of the construction lshown in Figs. 5 and 6. heater G is connected through a plug y screwed The turbine comprises a casing forming a into an aperture c3 in the wall or the chamber chamber A containing a series of fixed blades a with a source of electrical supply which can be alternating with a series of moving blades h aiswitched oft when the hns or ribs F have been mi xed to the shaft B whichrotatesjwithin the casraised to a suilicient high temperature to cause ing. An exhaust outlet al for the-spent' gases is the combustion of the :mixture when in the provided in the chamber A through which the chamber. The use of the heater plugs Gis only gases escape after acting on the blades a and necessary for a short time on starting up as afterb to rotate the shaft B. 4 wards the combustion of the mixture will main- 55 perature to continue the combustion of each successive charge.
The air for combustion is supplied under preslsure to each combustion change C from an annular air pipe H connected at h to a fan or pump and by the pipes hi with the air inlet c of each chamber which inlet is, as has been previously stated, controlled by the valve D.
The fuel is supplied toeach combustion chamber by a pump which is connected to suitable atomizing devices J arranged in the fuel inlets c1.
After combustion the gases pass from each chamber C to the turbine chamber A through the outlet cn controlled by the valve E.
The valves D and E are driven from cam shafts driven through worm gearing from the turbine shaft B. In a turbine having four combustion chambers as illustrated in the drawings two cam shafts K1 and K1 are employed arranged at right angles to the longitudinal axis of the shaft B and driven therefrom through the worm K and worm wheels k. Each shaft Kl or K2 carries four cams k1, k2, k and It* arranged in pairs, the cams k1 and lc3 of oneshaft Klfcontrolling the air inlet valves D of two adjacent combustion chambers and the cams k and If:4 of the same shaft controlling the outlet valves E of the same chambers to the turbine chamber A. The cams k1 and lc3 of the other shaft Kz similarly control the air inlet valves D of the other two' chambers C and the cams Ic2 and k4 the outlet valves E thereof.
'Ihe cams k1, k. k3 andJc4 operate the valves D and E through pivoted levers l1, l, I3 and 14 which act on the ends of the valve rods d ande and move them against the action of the springs d1 and e1 which act to keep the valves closed.
'Ihe cams k1, k?, k3, lc4 are so positioned on the shafts K1 and K so that each chamber C will receive the combustion air and deliver it to 'the turbine chamber A in succession and not simultaneously thereby giving a more even flow to th turbine blade a, b.
supply pump may be employed and the supply of f uel to each chamber be controlled by a suitable distributing valve.
An internal combustion turbine according to the invention is particularly applicable for use with heavy oil as fuel and can be used generally for propulsion purposes such as for aircraft and road vehicles and also for marine and power plant purposes.
What we Iclaim as our invention and desire to protect by Letters Patent is:
1. In an internal combustion turbine of the type referred to in combination combustion chambers, a plurality of internal fins extending the whole length of the combustion chamber and curved transversely and arranged obliquely and splrally to the surfacel thereof and rings attached at each end of the fins to secure them together into a tapered unit which can be readily inserted into and removed from the chamber.
2. In an internal combustion turbine of the -type referred to in combination combustion chambers, a plurality of internal fins extending the wholelength of the combustion chamber and curved transversely and arranged obliquely and splrally to the surface thereof, a plurality of points on the inner edge of each fin which will readily vbecome incandescent during normal working dueto the heat of combustion within the chamber and ignite the charge of injected air and fuel and rings attached at each end of the fins to secure them together into a unit which can be readily inserted into and removed from the chamber.
3.
