LEOPOLD V. FICHET, OF NEW YORK, N. Y.

lMPROVElVIENT IN STEAMFSUPERHEATERS.

Specification forming part of Letters Patent No. 52,982, dated March 6, 1866.

To all whom it may concern:

Be it known that I, L. V. FIGHET, of the city, county, and State of N ew York, have invented a new and Improved ,Apparatus for Superheating Steam; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in Whichp Figure l represents a transverse vertical section of this invention. Fig. 2 is a longitudinal section of the same.

Similar letters of reference indicate like parts.

This invention relates to an apparatus in which the steam generated in a suitable generator or boiler is passed through a series ot 4passages made in a solid mass of cast-iron or other suitable material, (by preference in a horizontal directiou,) said mass being exposed to the heat of a re and provided with suitable passages, through which the rc circulates in suoli a manner that by the action of a com para tively small tire the solid mass can be kept in an incandescent state and the steam still passing through the steamlp'assage is highly heated without producing any injurious eli'cct on the mass through which it passes. The steampassages passing through the solid mass are soarranged that their ends terminate in different compartments of chambers, which are secured to the ends of said solid mass in such a manner that the steam is compelled to travel in a zigzag course through the solid mass, and is exposed to the iniiuence of the heat for a longer time than it would be if made to pass in a direct course through lthe steam-passages.

A represents a steam-generator ot' any suitable construction. The steam emanating from this generator is passed, by means ot' a pipe, through a series of passages, b, in a solid mass, B, of cast-iron or other suitable material. This mass is placed over a furnace, C, and it is provided With a series of vertical passages, c, the passages I) being arranged, by preference, in a horizontal direction. rIhrough the passages c pass the heated gases rising from the re which may be built in thefurnace O, and which strikes the solid mass B from all sides, so that the same can be kept/in an incandescent state with a comparatively small expenditure of fuel.

The steam-passages b terminate in chambers D, which are secured to the ends of the mass B, and these chambers are divided by a series oi' horizontal partitions, d, into a number ot' compartments, so that the steam is compelled to pass through the first series of passages, return through the second, and so forth, as indicated by the arrows marked thereon in Fig.2.

While passing through the passages in the mass B the steam is highly heated andthe influence ofthe heat is considerably increased by compelling the steam to pass through the passages bin a zigzag course, and by using a solid mass, B, the injurious inuence ofthe products of combustion and of the superheated steam on the passages is little felt and produces no injurious influence, Whereas in an ordinary ap.

paratus, where pipes are used, such pipes are liable to burn out and to cause endless trouble. When drawn from the mass B through the discharge-pipe c the steam can be used for manufacturing or for heating purposes, or, in fact, for any purpose whatever. It retains its full pressure, and the pressure is increased by the action oi' the heat, so that it can be used for the purpose of giving motion to the piston of an engine.

This apparatus can be made of any desirable size, and it gives the most economical means to snperheat steam Without producing any possible injury to the incandescent mass through which it passes. y

I claim as new and desire to secure by Letters Patentl. Au apparatus for superheating steam, composed of' a mass, B, provided With a series ot' steam-Isiassages,v I), and a series ot' heatingpassages, c, substantially as and for the purpose described.

2. The chambers D, with partitions d, in combination with the solid mass B, substantially as and for the purpose set forth.

The above specification of my invention signed by me this 27th day ofDecember, 1865.
