Abstract: 27,019. Villepigue, D. A. F. de. Dec. 27. Gas turbines.-A turbine comprises three chambers, namely, a turbine chamber c, Fig. 1, a compressed-air chamber a, and an explosion chamber b, the last being situated between the other two. The cycle of operations is as follows :-The mixture is exploded in the central chamber and passes to the turbine chamber, actuating the turbine ; compressed air then passes from the end chamber, through the explosion chamber, and thence into the turbine chamber, thereby cooling the turbine. A shaft e passing through the three chambers carries rotors d between which are situated guide-disks g. In the air-compressing chamber, a part a<2> serves as an external bearing for the shaft e and as an internal bearing for a rocking pinion h, Figs. 1 and 4, actuated by a rack i. A pin j<1>. is secured to the pinion h by a collar, and is oscillated in a segmental slot in the head of the chamber. The function of the pin is to oscillate two disks k, k<1>, formed integral with a sleeve and mounted on bearings a<3>, b<3>.The walls of the explosion chamber and the disks k, k<1> are provided with apertures which periodically register. The wall between the turbine and explosion chambers is also provided with spring shutters n, Fig. 6, through which the exploded gases pass to the turbine chamber. The shutters are normally kept closed by external springs o', the tension of, which may be adjusted by means of a nut o<2>. The shutters communicate with inclined passages n' leading to the turbine chamber. The oscillation of the disks k, k<1> is effected as follows :-The rack i which rocks the pinion h is reciprocated by a cam p, Fig. 4, secured to a vertical spindle p<1>, which carries askew pinion gearing with a worm on a countershaft r.. The end of the rack carries a pinion s<1> fur compressing air in a cylinder s, which provides pressure in the hydrocarbon tank sufficient to force the hydrocarbon through an injector to the explosion chamber. A rod t<1> actuates the lever of a four-way plug cock which controls the admission of hydrocarbon and air to the injector by way of which the mixture is admitted to the explosion chamber. The compression chamber a carries bellows a<4>. The countershaft r drives an air-compressor of the Roots' blower type for the supply of air to the chamber a, actuates the mechanism for oscillating the disks k, k<1>, and carries a belt pulley by which the power is transmitted. The countershaft is driven by the main shaft off double gears r'. The mixture in the explosion chamber is ignited electrically in the usual manner. When the explosion takes place, the apertures of the disks k, k<1> are out of register with the aperture in the walls, but those in the disk k<1> are in register with the spring shutters n, through which the gases pass and actuate the turbine. The three chambers are then placed in common communication, and air passes from the chamber a to the turbine chamber by way of the chamber b. In a modified form, each disk k, k<1> is comprised of two thin disks slit in radial directions, the slits not being coincident. The composite disks are pro-, vided with apertures as in the other form. Each composite disk is made integral with a separate sleeve, the two sleeves being telescopically connected. The disks are pressed apart by a spring- controlled cam device and thereby press tightly against the walls of the chamber.
