IMPROVEMENT IN APPARATUS FOR OBTAINING TAR FROM SEA-WEED.

Specication forming part of Letters Patent No. 167,410, dated September 7, 1875; application filed July 20, 1875.

To all whom it may concern:

Be it known that I, WILLIAM H. RUDDICK, of Boston, of the county of Suffolk and State of Massachusetts, have made a new and useful .Invention for the Distillation of Sea- Weed; and I do hereby declare the same to be fully described as follows, reference being had to the accompanying drawings illustrative of the apparatus I use for such distillation, and of which- Figure l denotes a front elevation, Fig. 2 a longitudinal and vertical section, and Fig. 3 a top view, of the said apparatus.

I accomplish the carbonization and distillation of the sea-weed by means of the volatile products of combustion of fuel passed directlyT through a mass of the weed inclosed in a grated kiln, communicating directly with a condenser.

In the drawings, A denotes a kiln, provided with a grate, a, and an arch-cham ber, b, there being to the kiln an opening, c, in its side, on a level with the grate, and also afloor, d, to said opening. It also has an opening, e, to its ash-pit, with a door, f, thereto; and, furthermore. it has an opening', g, in its top, with a slidedoor, h, thereto, this latter opening being used principally for ijlling or supplying the kiln with the sea-weed. On one side ofthe kiln, and below it, is a stove or furnace, B, made like the kiln, except that to its opening in its top there is a pipe, O, leading directly into the ash-chamber of the kiln. From the upper part of the kiln a pipe, D, leads into a condenser, E, placed within a cistern, F, (to contain water,) and provided with an educt, Gr, leading through one side of the cistern. The kiln, as well as the furnace, has one or more pipes, H H, for discharging air from an air-blast apparatus into the ash-pit of each, each of said pipes H being connected with its ash-chamber, if desirable, by several branches, I I, provided with dampers, whose handles are shown at K.

In operating with the said apparatus, the kiln is to be charged with dry sea-Weed, and

denser, the tar and liquid hydrocarbons distilled passing from the condenser at the saine time.

If desirable, in order to facilitate the process, the sea-weed on the grate of the kiln mayV be set on fire, and more or less air, as occasion may require, may be thrown into the ashpit of the kiln.

After the charge of sea-weed may have been deprived of its hydrocarbons and reduced to charcoal, it may be lXiviated, to obtain from it the iodine or other matters contained in it.

Sometimes the grated kiln may be used with the condenser, without at the saine time using the furnace, to produce the vola-tile products of combustion, these being obtained by setting' lire to the mass of sea-weed at its bottom; but, as this causes a costly Waste of the sea-weed, it is better to make use ofthe furnace, with its separate charge of fuel.

I do not claim, for the distillation of peat or other matter, a retort with a furnace applied to heat it externally, in which case the volatile products of combustion of the fuel are supposed to escape through the chimney of the furnace, and are not carried through the material to be condensed and distilled.

I claim- The combination of the furnace B, the grated kiln A, and the condenser E, connected by pipes C D, and furnished with one or more airblast pipes to lead into the furnace or into the kiln, or both, as specified.

WILLIAM H. RUDDIOK.
