JEROME R. GEORGE, OF WORCESTER, MASSACHUSETTS, ASSIGNOR TO MORGAN CON- STRUCTION COMPANY, OF WORCESTER, MASSACHUSETTS, A CORFORATION OF MASSACHUSETTS.

GAS PRODUCER.

Application led July 1, 1915.

To all whom t may concern:

Be it known that I, JEROME R. GEORGE, a citizen of the United States, residing at lVorcester, in the county of Worcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in a Gas Producer', of which the following, together. with the accompanying drawings, is a specification.

The present invention relates to gas producers, and has particular reference to an improved construction by which the discharge of ashes from the producer is facilitated, and by which the blast of air, or air and steam, used to support the combustion of fuel in the producer is introduced and distributed at the level of the ash supporting surface.

The features of my invention are fully set forth in the following description and pointed out in the annexed claims, reference being had to the accompanying drawings, in which- Fig. 1 is a vertical sectional view of a gas producer embodying my invention, the section being taken on line 1 1, Fig. 2.

Fig. 2 is a horizontal sectional view on line 2 2, Fig. 1.

Fig. 3 is a fragmentary plan view of the bottom of the ash support, and

Fig. el is a detail sectional view on line elf-ll, Fig. 2.

Similar reference characters refer to similar parts in the different figures.

The gas producer embodied in my invention contemplates a rotatable main or fuel section 1, within which the level of the bed of fuel is maintained at or near the line 2, Fig. l. The combustion chamber surrounded by the section 1 is enclosed at the top by a stationary cover section 3 having a depending apron L t which projects into an annular water jacket 5 surrounding the shell of the main or fuel section 1, to provide a water seal against the escape of gases from the combustion chamber. The cover section 3, which is supported from posts 6 or the like, provides the usual conduit 7 for conveying away the gases produced within said chamber, and also provides the usual opening 8, having a removable cover 9, to pernnt the replenishment of fuel within said chamber.

Disposed below and spaced from the lower Specification of Letters Patent.

Serial .'No. 37,571.

edge of the fuel section 1 is a circular water pan 10, from the edge of which depends a preferably integral, annular ash trough 11. To the under side of said trough is attached an annular bevel gear 12, which also provides an annular track 13, by means of which the water pan 10 is rotatably sup ported upon a plurality of rollers 14, in the present instance three in number, one of which is shown in Fig. 1. The water pan 10 provides a plurality of shelves or lugs 15, in the present instance three in number, one of which is shown in Fig. 1, and each shelf or lug supports a column or post 1G rigidly attached at its upper end to a flange 17 carried by the shell'of fuel section 1. In this manner the fuel section 1 is supported by, and held spaced away from, the water pan 10, the two parts being adapted for rotation in unison, in the manner hereinafter specified.

The water pan 10 provides a central upstanding hub 18, and also a plurality of concentric annular upstanding partitions 19, E20 and 21, which are gradually reduced in height toward the outer edge of the pan. In this manner a series of annular water chambers Q2, 23 and 24; are produced, within which the cooling water is maintained at different levels, as shown in Fig. 1. The ovcrfiow of water from the water jacket 5 is received by a pipe 25, communicating with one of the columns 16, Fig. 1, which is made hollow for this purpose. The lower end of said column 16 is connected to a horizontal passage 26, formed on the bottom of the pan 10 and passing under the several partitions 19, 20 and 21, opening into the innermost and deepest water chamber 22. The overflow from each water chamber supplies in turn the next adjacent shallower chamber, and the overflow from the outermost and shallowest chamber 241 passes into the concave trough 11 formed on the edge of the water pan. It is to be understood, of course, that any numb-er of water chambers, arranged as above described, may be provided in the water pan.

The gradual outward descent of the series of annular partitions 18, 19, 20 and 21 provides for the support thereon of an annular plate 27, frusto-conical in form, which serves as the fuel and ash supporting surface of the producer. Said plate 27 is atof one of these columns can be accon'iplished Without providing any temporary support for the fuel section, and the ash support and blast structure can be removed through the space thus made available.

The Water jacket 5 of the fuel section is formed by spaced inner and outer plates surrounding the usual lire brick lining. An annular plate 52, forming the bottom of the Water jacket, has a substantially vertically disposed portion 53 to which the innerjacket plate is secured, and a horizontally disposed shelf 54 providing for the erection of the brickwork thereon. The outer Water jacket plate being attached. to the inner Wall of trough 5l, it will be clear that the construction shoivn and described avoids the necessity for Hanging the plates Which are used to form the bottom and sides of the Water jacket.

The ashes crowded into the rotating trough 1l by the arms 34 may be removed therefrom by the use of a stationary inclined blade 55, F ig. l, in the manner common to devices of this class. The constant rotation of the section 1, containing the bed of fuel, enables the use of a fuel evener 56, of a type known in the art, requiring a relative traversing movement between it and the bed of fuel, for levelling the surface of said bed.

By the arrangement and disposition of parts shown and described, which makes it possible for the blast to be discharged at the level of the ash supporting surface, a producer of much less height than the ordinary types of mechanical gas producers is Drovided. The support provided for the ashes is entirely dry at all times, in distinction to producers in which the ash pan utilized in the formation of a Water seal, vet all danger of overheating' said supportlis absent, owing to the cooling furnished by the water pan beneath the same. The location of the blast structure in immediate proximity to 'the ash supporting surface, rather than at a distance above the same, as in prior constructions, insures an ash bed of uniform character, since there is no obstruction to the passage of ashes onto the surface of the support.
