IMPROVEMENT IN GAS AND OTHER RETORTS.

Specification forming part of Letters Patent No. 45,908, dated January 17, 1865, antedated January (i, 1865 Reissue No. 2,000, dated June 20, 1865.

To all whom it may' concern:

Be it known that I, JOHN CHILCOTT, of Brooklyn, in the county of Kings and `State of New York, have invented a new and useful Improvement in Gas and other Retorts; and I do hereby declare that the following is a full, clear, and exactl description of the same, reference being had tothe acompanying drawings, formin g part of this specification, in which- Figure 1 is a front view of a retort with my improvement. Fig. 2 is a central longitudinal vertical section of the same. Fig. 3 is a transverse section of the same in the planeV indicated by the line at' .r in. Figs. 2 and 4. Fig. 4 is a horizontal section of the retort-casing below the retort.

Similar letters of reference indicate corresponding parts in the several figures.

The object of this invention is to heat one or more retorts in a more economical manner than under the system heretofore practiced by reducing the consumption of fuel and to this end it consists in surrounding one or more retorts with a continuous system of iiues, through which the flame and heated gaseous products of combustion from the furnace may circulate back and forth several times along and once all around the retort or retorts before escaping to the chimney.

It also consists in a certain construction of such a system of fines whereby provision is made for cleaning them.

To enable others skilled in the art to make and use my invention, I will first describe the example represented in the drawings, and afterward describe brieiiy certain modifications.

A in the drawings is the retort made of fireclay or cast-iron, of the usual D-shape represented in Fig. 3, or of other suitable form, and having a movable head, B, at the front end.

C is the jacket or casing of the same materia-l as the retort, and having a transverse sectional form corresponding with that of tl e retort, but of considerably larger area, so as to provide a sufficient space between its interior and the exterior of the retoI ts all around to form the lues E E. This jacket or casing is somewhat shorter than the retort, so that the retort fitting close against its closed rear end may protrude some distance from its rear end, as shown in Fig. 2. The open front end of said casing is constructed with an external projecting flame, a, at its top and sides, to which to attach movable head-plates F and G by screw-bolts b b, for the purpose of closing the front of the flue-space between it and the retort, the said plates fitting closely around the exterior of the retort.

c c are'the longitudinal partitions between the retort and the jacket or casing which di vide the intermediate space into iiues E E, arranged at equal distances apart all around the retort andjacket, those which are between the flat bottoni and sides of the retort and jacket being at right angles thereto, and those between the arched tops thereof' being radial thereto. These partitions are formed upon the interior ot' the jacket and tit closely to the exterior of the retort, and they extend the whole length of the retort and jacket, exceptl that in each there is an opening, d, the said opening in one being at the front end, and that in the next on either side being at the other end, as shown in Figs. 2 and 4.

The retort is supported within the jacket C by resting on the upper edges of the partitions c c.' 4

iis the inlet-opening in the jacket leading to the system of fines E E. This opening is situated in the bottom at the front end and close to the left-hand side of the retort and jacket, as shown in Figs. 3 and 4.

eis the exit-opening in the lowest flue on the left-hand side of the retort, next to that flue in which is the inlet-opening i, as shown in Fig. 3'.

The opening d in the partitions c c are respectively so arranged relatively to the inlet and exit openings i and e that the flame and heated gaseous products of combustion from the furnace,' entering one iiue at the inlet opening, may pass in a rearward direction along that iiue, return in a forward direction by the next one at the righthand, repass in a rearward direction along the next, and so on through all the iiues under the bottom of the retort, thence back and forth through those on the right-hand side, afterward through those on the top, and finally through those on the left-hand side, thus making the complete circuit of the retort, and escaping by the exitopening.

i In order to provide for the removal of the retort from the jacket and introducing a new retort or jacket, thejacket is divided horizontally and longitudinally into two parts, which are iitted together with tongues and grooves, as shown at g g in Fig. 3.

The cleaning out ot' the iiues may be eiected by taking oft' the removable headplates F and G, the junction of which corresponds with the junction of the upper and lower portions of the jacket. To obviate the necessity of taking ott' these heads, there may be provided therein a series of openings, one opposite to each iiue, the said openings being iitted with removable bonnet-plates h h, as shown in Fig. 1.

Any convenient number of retorts, each fitted with a Hue-jacket, C, or otherwise surrounded with a system -of tlues, E E, similar to that described, may be arranged in one bench, provided the inletopenings z" ofthe several jackets or system of surrounding lues are properly arranged with respect to the tire place or furnace, and the exit-openings e are properly arranged with respect to the chimney, that all the dames and heated products of combustion may pass through the jackets or system of 'fines on their way to the chimney, the flame and gaseous products being properly divided between the severaljackets or systems ot' fines surrounding the several retorts.

Each jacket C or system of iiues E E may be provided with more than one inlet-opening, and more than one outlet-opening, if the openings d in the partitions c c are properly arranged. They inlet and outlet openings may be reversed-that is to say, e may be the inlet and t' the outlet.

Although I consider it preferable, when several retorts are arranged in one bench, to completely surround each retort with a separate and distinct system of iues such as l have described and represented in the accompanying drawings, a similar continuous surrounding system or fines may be made to embrace within its circuit two or more retorts or the Whole set.

What I claim as my invention, and desire to secure by Letters Patent, is-

l. Surrounding one or more gas or other retorts with a continuous system of tiues, E E, through which the iame and gaseous pro ducts from the furnace circulateback and forth several times along and once all around the retort or retorts, substantially as and for the purpose herein set forth.

.2. The jacket or casing, C, divided longi tudinally into two parts, and having the i'lue partitions attached to its interior, so as to be detachable from the retort, substantially as and for the purpose herein specified.
