subject of the German Emperor, residing; et lliennheim, in the Empire of Germany, lieve invented certain new and usefullinprove ments in GasTurbines, of which the follow in is a specification.

ily invention relates to gas turbines with combustion chambers which are providedL with controlled Ineens for closing there, and lies for its object on improv/eil,construction of such e machine for the purpose ol allowing the freest possible alteration in the torni t the combustion chambers under veristions of temperature both relatively to the other ports of the machine, for cssing, and also to one smother.

The invention is of particular importe-nce for gas turbines of the kind in which the periodically posed to unequal strain, es, for instance, Where for the purpose of regulating the certain instance, the

power or number of revolutions, chambers are temporarily unutilizefl'. The 'niproved construction of ges turbine is mei ly characterized by the combustion chambers being substantially only rigidly connected With one another st their bottoms, the 4srrsngement for feedingtlie individuel olninibers being placed in this zone of con nection, While that port of the combustion chambers from which the hot gases of coinbustion flow into the turbine is .so formed thnt it can move, if desired, with the other parte mounted on it, :is freely es possible relatively to the other ports of the mechine.

ln order better to explain the invention, reference Will now be mede to the accompanying drawings, in which two forms of construction of the machine are shown es examples.

lligure 1 is an axial section of that port ol the ges turbine which constitutes the invention; Fig..2, n similar View of a, modiecl forni of construction.

According to Fig. l, the combustion chombers a are :irren ed in e circle around the vertical shaft g oi the turbine and connected with one44 another by en. annuler port lb, which also :forms part of the machine. The ges chamber which is 'provided in the bese oi? tontidstion may be connected With the combustion chambers a by means olf controlled valves o. for feeding the combustion elsewhere.
