IMPROVEMENT IN STEAM-GENERATORS.

TO ALL WHOM IT MAY CONCERN:

Be it knownthat I, QUINTIN PARKER, of the city, county, and State of New York, haveinvented a new and improved Locomotive-Boiler; and I do hereby declare the following to be a full, clear, and exact description thereof, which will enableV others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming a part of this speciiication.

i Figure l represents a longitudinal section of my improved steam-boiler;

Figure 2 is a horizontal section ofthe same, taken on the plane of the line a; x, fig. 1.

Figures 3, 4, and 5 are detail longitudinal sections of boilers now in use.

Similar letters of reference indicate corresponding parts.

This invention relates to a new construction of locomotive-boilers, and its object is to'producc a. boiler in which the lower llues cannot be-clogged by cinders and ashes.

The invention consists chieiiy in a discharge-channel, through which the ashes', cinders, and other impurities can, from the inclined plate in the `rear of the Hue-sheet, fall to the ground, or into the ash-pan, so that thereby the lower lues are kept clear from obstruction.

A, in the drawing, represents the shell of a locomotive-boiler.

B is the furnace-top C, the grate.

D, the due-sheet.

The lower end of' the Hue-sheet is, by means of an inclined U-shaped plate, E, connected with the front plate a ofthe furnace.

It will be seen that the front end of the lower arm b of this plate E is in line with thebottonl plate c of the shell A. n i

G is a channel or discharge-ppe, extending downward from the lowermost and front part of the upper arm d of the plate E. The pipe G passes through the lower part of the shell A forthis purpose.

The upper end of the pipe G may be bifurcated. v

The' iiame will, from the grate, pass up over the plate E, and then forward into the dues H, that' project from the flue-sheet. Any cinders or ashes carried by the flame over the rear bend of the plate E, will be discharged again through the pipe G, and, besides this, a small, convenient replace is produced,

Heretofore boiler-furnaces were at rst made square, but, .when it was found that thereby the ame would be directed upward, and burn the {lue-sheet and the frontends of the lues, a forward extensionwas provided, as in iig. 8. i p

This, however, was not protable, as the iireplace became so large as to consume too large a quantity of fuel.

To improve this, the deiector was introduced, as in iig. 4, or the split furnace, as in fig. 5.

In either of these cases, the inclined backward extension would serve as a convenient support for ashes, cinders, Ste., carried up by the flame,` and by them the lower dues soon became stopped up.

The deiiectors here shown were all too low, their Aupper plates being in line with the bottom of the shell.

The lfront part of the fireplace thus becomes too low.

It will be noticed that the upper arm d of my inclined extension Efreaches in front of the front piste of the furnace, and that the flue-sheet is also somewhat set forward, so as to allow the application of the pipo G in front ol' the furnace, as shown.

The pipe G also serves to carry fresh air into the boiler, to improve combustion.

I do not claim the arrangement of the detlector E, nor its use as a water-chamber.

. Having thus described my invention, what I .claim as new, and desire to secure by Letters Patent, is-

' The combination ofthe pipe G with the boiler-sheet A, suspended from the upper plate of the deilector E, in rear of the ue-sheet, substantially as herein shown and described.

QUINTIN PARKER. Witnesses:
