UNITED STATES PATENT OFFICE.
JOHN E. GILL, OF FRANKLIN, PENNSYLVANIA.
. FEED-WATER HEATER.
SPECIFICATION forming part of Letters Patent No, 374,956, dated December 20, 1887.
Application tiled September 1, 1887. Serial No.248,443. (No model.)
To all whom it may concern:
Be it known that I, JoHN E. GILL, of Franklin, in the county of Venango, State of Pennsylvania, have invented certain new and useful Improvements in Feedater Heaters, of which thefollowing is a specification.
My invention is specially applicable tolocomotives using petroleum or its residuum as fuel, for the reason thatin such a locomotive a forced draft is obtained by means of a blast applied in the fire-box, instead of the draft produced by the escape of the exhaust-steam from the cylinder.
The object of my invention is to obtain economy of fuel by heating the feed-water to the highest practical point before introducing it into the boiler, utilizing therefor the waste heat of the escaping gases of combustion.
Myinvention consists of the combinations hereinafter described, and pointed out in the claims.
The accompanying drawing shows a side view ofa locomotive embodying my invention.
A locomotive is provided with two stacks, A and B, or with a single stack having a vertical partition. One stack, A, is simply for conveying the exhaust-steannand as the exhaust is not used to produce the draft exhaustnozzles and their accompanying back-pressu re are dispensed with. The second pipe, B, permits the escape of the products of combustion whenever they are not needed for heating the feed-water, in the manner hereinafter described. Leading from the side of the stack B is the curved pipe D, which is led byany convenient course back to the tender F and through the water-tank thereof, terminating at the rear of the tender. There may be several convolutions of the pipe D in the tender F; but'I prefer to provide the requisite heating surface by increasing the diameter rather than the length of the pipe. The pipe D has an expansion or flexiblejoint at E, joining the locomotive and tender-sections.
To regulate the flow of gases in the pipe D,
a damper, O, is provided at its junction with the stack B. This damper is hinged at its upper edge, 0, so that its lower edge can be swung into the stack B, thereby deflecting a part or all of the gases into the pipe D, accordingly as it is swung partially or entirely across the stack B.
A pipe, H, is led from the boiler of the 10- comotive to the rear of the pipe D. A steamjet from this pipe may be used to produce a draft in the pipe D,to assist in maintaining the flow of gases through said pipe D. The upwardly-projecting portion of pipe D in the rear of the tender may be prolonged, so as to project above the roofs of the cars, or the opening of the pipe D may be turned downward, if desired.
I claim- 1. In alocomotive, the combination of separate escape-passages for the exhaust-steam and furnace-gases and a pipe leading from the es cape-passage for the furnace-gases through the water in the tender.v
2. In a locomotive, thecombination of separate escape-passages for the exhaust-steam and furnace-gases, a pipe, D, leading from the escape-passage for the furnacegases through the water in the tender, and a damper, O, for regulating the flow of gases through the pipe D.
3. In a locomotive, the combination of separate escape-passages for the exhauststeam and furnaces-gases, a pipe, 1), leading from the escape-passage for the furnace-gases through the water in the tender, and a steam-jet pipe, H, for producing a. draft in the pipe D.
4. The combination of the steam -exhaust stack A, the furnacestack B, the pipe D, passing through the tender, the regulating-damper G, and the steam-jet pipe H, as and for the purpose set forth.
JOHN E. GILL.
