portion of the cone or is supported by rolls which are provided with axles e turning in fixed bearings, and the upper portion by means of balls 7" rolling upon a track fast with the twyer tube 0 which forms the axis of the whole system. Thus as above stated the conical .form of the grate a and the inclination of the thread or steps b may vary as desired and they may moreover in each case vary from one point of the cone to the other. In certain cases, especially when the cone a is relatively flat, the central series of carrying balls or rollers f may be omitted.

The apex of the cone a is formed of the cap 9 of the twyer which is also conical and formed with helicoidal steps h. Blowing orifices z are provided at the lower portion of the cap, which in their rotation distribute the air and steam uniformly throughout the T 0 all whom it may concern:

Be it known that I, Innumi ALEXIS CHA- VANNE, of St. Chamond, Loire, France, engineer, have invented a new and useful ha .5 provement in Gas Generators, which improvement is fully set forth in the following specification.

This invention able grate for .gas

has for its object a movgenerators the continuous rotation of which at a suitable speed automatically maintains the zone of combustion at the desired height. For this purpose the movable grate is provided with spiral steps screwing so to speak into the combustible be arranged in one or more helices; the general form of the grate is that of a cone turning about its aXis which preferably coincides with that of the pipe leading air and steam to the midst of the combustible, and provided at its apex combustible mass. The cap 9 may be fixed with a blowing cap which may be fixed or but this is usually not advisable.

The conical form of the grate as vided with teeth j, which may be cast with well as that of the inclination ofthe steps it, withwhich gear a bevel pinion 7a keyed with which it is provided should be deterupon a driving shaft Z, the shaft Z is driven mined by taking into consideration the na in any suitable manner which permits of ture and the size of the combustible fuelas stopping or reversing when desired the diwell as that of the movement which it is derection of rotation. sired to impart to the various portions of the The movable grate or cone 64 almost enmass. In effect, when the angle of the apex tirely fills the lower'end of the gas generof the cone is too acute, the central portions ator, so as to efiiciently expel the burned of the combustible mass pass downward too portions of the charge at the sides; it is conrapidly, the peripheral portions remaining nected through its have with a floor an of behind. The contrarytakes place when the masonry, for example, formed as a basin and cone is too fiat, and a suitable angle for the filled with water into which an annular plate conical bottom and for the steps is one which n .dips ;thisplate forms the lower portion of gives a uniform descent of the combustible the body of a gas generator of any suitable mass at all points of the gas generator. The construction. .movable stepped grate almost entirely fills As will be seen in the drawings the lower the lower end of the gas generator an is edge of the wall a which may be cylindrical or conical is preferably in a line with the outer edge of the cone (1. This plate n forms a water seal while leavingbetween its lower edge and the floor m a space sufficient for the removal of the cinders and slag.

In order to-prevent the cinders and other impurities passing into the driving mechanism of the movable grate a and consequently hindering its movement, there is arranged at the lower portion of the basin m a ring 0 of fiber, wood or other suitable ma terial rubbing upon the periphery of the cone a and retained by a metal washer p and tightening plate g, It is not necessary that this stuffing box 0 should prevent the passage of water contained in the trough m, which connected at its base with an ordinary form of trough formin-ga water seal, preferably with the interposition of a suitable stufiing box for preventing cinders from passing In the accompanying illustrative drawings: Figure 1 is a partial vertical section of the lower end of a gas generator, provided with the movable bottom which forms the subject of the present invention. Fig. 2 is an elevation'of this grate, and Fig. 3 is a plan of the same.

In these figures a is the conical movable grate provided with spiral steps b and rothrough which the incoming air and steam pass. The lower tatable cone having a erator, a twyer arranged may even, especially if care be taken to add a little soap or other lubricant, serve to lubricate the driving parts of the cone a. An ordinary stufiing box 1* is in this upon the shaft Z at the place where it emerges from the apparatus.

The apparatus works as follows: As the movable grate a supports the mass of the fuel decomposed tion in the gas generator, it results that in its movement of rotation, the spiral Z) which forms a support in the form of ascrew hav ing one or more threads allows the mass to move downward in a regular manner; the

the trough m being pushed outward. charge should bind and adhere together it can easily be separated and to a certain extent broken up, by reversing for a short time the direction of rotation of the stepped cone so as to produce a lifting of the mass.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed I declare that what I claim is:
