EMPROVEMENT IN STEAM-JETS FOR FURNACES.

Specification forming part of Letters Patent No. 160,480, dated March 2, 1875; application filed September 3, 1874.

To all whom it may concern:

Be it known that I, GEORGE STEELE, of Mott Haven, New York city, in the county and State of New York, have invented an Improvement in Steam-Jets for SteamGenerator Furnaces, and for other purposes, of which the following is a specification:

This invention relates especially to steamjets in the flue or chimney of furnaces for marine engines and other boilers, whereby anartiticial or forced draft is produced. 1t essentially differs from other arrangements, in which there is combined with a steamjet a divided flue and a valve for one division of the flue, and in which jets of steam are directed up the central divided portion of the flue by a series of nozzles beneath, the annular space around the same being closed by segmental dampers, which are opened when a natural draft is used. My invention consists in a central steam-supply chamber or reservoir within the chimney, provided with radial gas-pipes or hollow arms, having detachable nipple or nozzle connections, arranged to give a most effective distribution of the jets within the chimney without interference with the natural draft, and dispensing with dampers; also using less steam than heretofore, and providing for contraction or expansion of the apparatus to suit different-sized chimneys.

Figure l is a vertical elevation or diagram of my improved apparatus applied to the chimney of a marine-engine boiler-furnace; Fig. 2, a mainly sectional vertical view of said apparatus on a larger scale; and Fig. 3 a partly sectional plan of the same.

A is a central steam chamber or reservoir,

in which a head of steam is kept or furnished to supply the several nipples or nozzles. B B are the radial pipes from said reservoir, made up in part of detachable nipple-connections 13 B carrying upwardly-projecting nipples or nozzles O O, at difl'erent distances apart in the length of the horizontal or radial pipes B B, and the outer connection B of said, pipes, or certain of them, having crosspipes and nipple-connections B 13 with attached upwardly-projectin g nipples or nozzles O C. By this construction of jet apparatus there is always-that is, when the steam is turned ona full supply of steam to the jets, and a most efficient distribution of the steam over the whole or greater part of the area of i the chimney, and but little steam used, while the apparatus in no way interferes with the natural draft 5 and, by the detachable screwconnections carrying the nipples, not only may any of said connections and their nipples be readily removed for repair, but nipples of different sizes and connections of different lengths maybe substituted to adapt the apparatus to dilferentsized chimneys. This jet is applicable to the ventilation of the holds or stoke-holes of vessels, Where its advantages are the same as in furnaces.

I claimlhe combination of the steam-reservoir A, the radial pipes B, the detachable nipple-connections B B and the nipples O O, substantially as and for the purpose herein set forth.

GEO. STEELE.
