SPECIFICATION forming part of Letters'Patent No. 593,865, dated November 16,1897. Application iled January 27, 1896. Serial No. 577,041. (No model.)
.To @ZZ whom it may concern:
Be it known that I, BENJAMIN TALBOT, a subject of the Queen of Great Britain and Ireland, and a resident of Pencoyd, Montgomery county, Pennsylvania, have invented certain Improvements in Gas-Producers, of which the t following is a specification. 1
My invention consists of certain improvements in that class ofgas-producers known as Water-seal producers which have the ash-outlet at the bottom closed'by a water seal, air under pressure being forced into the mass of ashes in the lower portion of the producer and rising therefrom into the superposed mass of incandescent fuel, the water seal preventing the escape of air through the ash outlet or outlets, but permitting the withdrawal of the ashes therefrom without arresting the operation ofthe producer.
The objects of my invention are to simplify the construction and thereby lessen the initial cost of the producer; to permit of the removal of ashes from any point around the producer; to provide for the ready change of the producer from forced tonatural draft, or vice versa; to insure the ready discharge of the contents of the producer when such discharge is required, and to facilitate repairs.
These objects I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which- Figure lis a vertical section of the lower portion ofa water-seal gas-producer constructed in accordance with my invention. Fig. 2 is a sectionalplan view onv the line 2 2, Fig. 1. Fig. 3 is a transverse section, partly in elevation, on the line 3 3, Fig.'2. Fig. 4 is a perspective view of one of the sections of the ashhopper, and Figs. 5, 6, and 7 are enlarged views illustrating the details of one of the poke-holes or draft-openings therein.
' A represents the body of the producer, which consists by preference of a cylindrical iron or steel shell or casing A with a lining of some suitable refractory material. The body of the producer is supported at some distance above the base or foundation B of the structure by means of a number of legs D, of which four are shown in the present instance, although 5o more or less than this number may be,V employed, if desired, it being advisable, however, to use as few as possible in order that free access to all parts of the bottom of the structure will not be obstructed..
The legs D may be made in any appropriate manner,those shown in the drawings being built up of ordinary structural shapes united to the casing of the producer-body and to channel-bars D, wl1ich constitute the boundary of the water-seal pit F, the latter being formed, preferably, of concrete or masonry, and being for convenience rectangular in form, as shown in Fig. 2, although this form may, as will be evident, be departed from to any extent, as circumstances may suggest, without affecting my invention.
Depending from the bottom of the producerbody A is an ash-hopper exposed externally to atmospheric pressure only and composed of a series of segments G, having at theiredges flanges a., whereby they may be bolted together, each of these hopper-segments G having at the top projecting ears b, so that when the hopper-sections are fitted together the ears of adjoining sections will meet and will form openings for the reception of bolts d, mounted in brackets c?, secured to the casing of the producer-body, thus providing for the suspension of the ash-hopper beneath'said body. The brackets d are slotted and the bolts d are provided at the top with heads d2, having a pi-votal bearing on said brackets, so that the depending hopper can have a lslight lateral movement to provide for shaking down the ashes therein, such movement being imparted by any suitable .means-as, for instance, bythe lever cl3 and link d4. (Shown in Fig 3.)
Another function of the movable ash-hopper is to cause the breaking up of clinkers and ash-lumps at the line of junction of the hopper with the fixed upper structure of the producer, the movement of the lower mass contained in the ash-hopper in respect to the fixed upper mass contained in the body of the producer causing aA grinding or scraping which efaction between these two masses fects the desired result.
The depending ash-hopper is of such depth that it will dip into the water in the pit F to IOO such an extent as to provide a seal of the proper depth, and in two diametrically opposed sections of said ash-hopper above the level of the water seal are formed flanged openings f for the reception of pipes g, which support a box or casing g', centrally located in the ash-hopper. Rising from this box or easing g is a short vertical pipe g2, having a cap ring or sleeve g3, upon which is mounted a double conical hood g4 g5. One of the pipes g has in the present instance a plug at the outer end, but the other communicates with any available means of supplying air under pressure, the preferred means being a steamjet, which induces a iiow of air into and through the pipe. The air rises through the pipe g2 and escapes from beneath the hoods g4 g5 into the mass of ashes inthe lower portion of the producer, through which it rises to the incandescent mass of fuel above the ashes. Air may be forced through both pipes g, if desired, or through either of them, as may be found to be most convenient.
rlhe water seal in the pit F prevents the escape of air downward from the ash-hopper, but permits of a withdrawal of ashes from beneath the same, and it will be observed that the said hopper is entirely free at the bottom, so that ashes can be Withdrawn at any point around the hopper, the slight amount of space occupied by the supporting-legs D of the producer-body constituting no practical obstruetion to such removal. It will be observed, moreover, that the ash-hopper is exposed on all sides to a free circulation of air, whereby the thorough cooling of the ashes before they reach the water seal is provided for and the formation of water-vapor which occurs when hot ashes are brought into contact with the water seal is prevented, this being a desirable result, as the rise of steam from the water seal to the incandescent fuel in volume greater than can be readily decomposed by the latter is in -practice always to be avoided.
By making the depending ash-hopper in sections one or more of the latter can be readily removed when it is desired to dump or discharge the contents of the producer without removing the entire hopper, and facilities are always afford-ed for repairing any part of the hopper which needs such repairs without disturbing any other portion of the structure.
In each of the sections of the hopper I form by preference a number of poke-holes or draft-openings t', each of which is surrounded by an external iiange vl, recessed for the reception of bolts i2, whereby are secured in place plates t3, which overlap and serve to retain in place bushings m, inserted in the openings t', these bushings being tapered for the reception of tapered plugs n, so that in the ordinary working of the producer the openings are all closed, any one of the plugs, however, being readilywithdrawn when it is poker or other implement for acting upon the ashes or clinkers contained in the ash-hopper, all of the plugs being withdrawn when it is desired to operate the producer by natural draft instead of by means of a forced blast of air. The bushings can be readily replaced when worn, thus .increasing the term of service of each section of the ash-hopper.
By the use of the exposed water-sealed ashhopper having an internal air-supply the poking of the ashes through the poke-holes of the hopper can be effected without cutting oif the air-supply, so that the producer is continuous in its action.
It will be evident from the foregoing description of my improved gas-producer that the same can be constructed without excessive initial cost and can likewise be maintained in operative condition with the greatest economy, while the practical operative requirements of easy removal of ashes, proper cooling of the ashes before they reach the water seal, and ready access to any and all parts of the lower portion of the structure have been properly met.
Having thus described my invention, I claim and desire to secure by Letters Patentl. A water-sealed gas-producer having a body supported upon legs above a sealing-pit, an ash-hopper suspended from said body and depending into said sealing-pit, said hopper being exposed to atmospheric pressure only, and having poke-holes forlned in it, and an internal air-supply pipe within the hopper, substantially as specified.
2. A gas-producer having a body supported above a sealing-pit, and an ash-hopper, exposed externally to atmospheric pressure only, said hopper being suspended from said body by means of bolts and depending into said sealing-pit, substantially as specified.
3. The combination of the elevated body of the producer, the suspended ash-hopper composed of sections secured together and each having projecting ears, with suspending bolts mounted in brackets on the body of the producer and passing through openings formed in the projecting ears of the hopper-sections, substantially as specified.
4C. A gas-producer divided horizontally and having the lower portion water-sealed and mounted so as to be susceptible of movement in a horizontal plane each portion containing a mass of fuel whereby the contents of said lower section are caused to move in contact with the contents of the upper fixed section at the line of division, substantially as specified.
5. The combination of the elevated body of the producer with the depending ash-hopper, suspending bolts therefor having heads pivotally mounted on said body, and means for moving the hopper transversely beneath the producer-body, substantially as specified.
6. The combination of the elevated body desired to insert through the bushing m a of the producer, with the water-sealed de- ICO IIO
