REVOLVING GRATE' FOR GAS-PRODUCERS.

To all whom "it may concern:

Be it known that I, HUGO REHMANN, a subject of the German Emperor, and resident of Biirgerstrasse' l0, li'liilheim-on-the- Ruhr, Germany, have invented certain new and useful Improvements in Revolving Grates for Gas-Producers, of which the following is a specification.

The invention relates to revolving grates for gas producers which are provided with a towel-like erection turning with. the grate it consists essentially in the surfaces of the grate being formed out of several steep turrets provided with openings. The.co1nbustible continually slips down the steep turrets and thus gets well broken up. The distribution of air is improved and the formation of large clinker-s avoided. In order to prevent the settling of slag or clinker on the wall of the gcnt-rator, and to prevent the baking together of the coal on the top of the grate, one or more lateral projections in the form of scrapers are arr: nged on the revolving grate which reach near to the wall of the gas producer. It is advisable to construct these projections with cutting edges, sothat the slag may be easily sc'aped off during the rotation of the grate.

In order to bring about a uniform introduction of the blast, it is led into each turret ot' the grate and in addition steam pipes are arranged in the blast. distribution pipes, which lead steam under the turrets of the grate as well each lateral projection in order to prevent the grate turrets from burning away while. working in the red hot cinders.

The drawing shows a form of construction .of the new revolving grate.

Figure l is a wrtical section, Fig. 2 is a plan. and hi 3 a partial side view of the revolving grate with a lateral projection.

The producer body 1'), which supported in the usual way, projects with its bottom end into the water seal basin 1 The latter is fixed on the plate '1. which is turnably arranged in any well known manner and which is provided with the towerlikc crection. In the form ofconstrimtion shown the arrangement of this erection is represented as being at the side of the axis of rotation (I, and around the middle lurrct at unequal distances from the same. there are four turrets 0, (Z, c and f. To the. underside of the grate plate 1" there is fixed an annular flange t which dips into a water Specification of Letters Patent.

seal n arraugedin the foundation u of the producer.

The plate 1' together with the turrets is rotated in the well known manner by a worm not shown in the drawing and engaging into a worm wheel 8 fixed to the plate 1'.

o is a lateral projection in the form of a scraper for removing slag from the wall 7) a of the producer. ()ne of such scrapers 0 may be provided on each of the outer turrets. These scrapers are best made hollow and provided with openings. Each of the turrets is likewise provided with openings g.

11. is the tube for leading in the blast, and its upper part is fixed to the grate itself. This upper part dips into the water seal 1:, and bears distributing pipes 7': leading into the turrets. In the tube h the steam pipe Z is arranged the upper part of which can turn in the collar m, and terminates in several branch pipes 41, which lead directly under the grate turrets and under the projection 0. If the grate plate is rotated the distribution pipes 7.1 and branch steam pipes at are also rotated, so that their position relalive to the turrets always remains the same.

By the rotating motion of the turrets 1ying at unequal distances from the axis of rotation, the combustible is moved toward the producer wall, and continually slips down the steep turrets and is thus well broken up; whereby the caking of the combustible and the settling of the latter on the grate is prevented, and a better distribution of the blast led in through' the pipes /L and 7.;

obtained. Moreover, by the scrapers .2 the combustible next to the producer wall 7) is broken up and the slag scraped oil from the latter.

In order to prevent the turrets of the grate and the scrapers 0 from burning away while working in the red hot cinders, steam is led under the turrets and the scrapers through the pipes Z and n. I

In the form of. construction shown around the central turret. there are four further turrets arranged. The scope of the invention will not however be exceeded, if more or fewer turrets tral one.

\Vhat l claim as my invention and desire to secure by Letters Patent is 1,

1. In a grate for gas producers in coinbination, a tower like erection arranged m the middle part of the grate plate and consisting ofa plurality of steep turrets integral are arranged around the cen-' central turret, means with each other and adapted to move the combustible toward the producer wall, said turrets being hollow and provided with apertures, means for rotating the said grate plate together with said tower like erection, and means for leading a blast of air into said steep turrets. substantially'as set forth.

2.- In a grate for gas producers in con1bination, a tower like erection on the grate and consisting of a plurality of turrets arranged at unequal distances from the vertical axis of the grate, said turrets being hollow and provided with apertures, means for rotating the said grate together with the said turrets, means for leading a blast of air into said turrets, and means for leading steam into said turrets,substantially as set forth.

3. In a grate for gas producers in combination, a tower like erection on the grate and consisting of a central turret and a plurality ofturrets arranged around the said for rotating the said grate together with the said turrets, a lat eral projection on one of the said outer turrets, said lateral projection having a cutting edge, said turrets and lateral projection being hollow and provided with apertures, means for leading a blast of air into said turrets, and means for leading steam into said turrets, substantially as setforth.

4:. In a grate for gas producers in combination, a tower like erection on the grate and consisting of a hollow central turret and a plurality of hollow turrets arranged around the said central turret, means for rotating the said grate together with the said turrets, lateral projections on said outer turrets, each of said lateral projections having a cutting edge and adapted to remove clinker from the walls of the gas producer, there being apertures in said hollow turrets and lateral projections, means for leading a blast of air into said turrets, and means for leading steam into said turrets, substantially as set forth.
