SUPERHEATER.
SPECIFICATIO forming part of Letters Patent'No. 562,575, dated June23, 1896. Application filed November Z9, 1895. `Serial No. 570,448. (No model.)
l To all whom t may concern:
Be it known that I, JOHN IV. CASEY,V of Sistersville, in the county of Tyler and State of West Virginia, have invented certain new and useful Improvements in Superheaters for Steam-Boilers; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.
This invention relates to superheaters for steam-boilers, and has for its object the provision of a superheater simple, cheap, and
durable in construction and easy of adjust` ment, and occupying a minimum amount of space in the fire-box.
A further object is to provide a superheater with no connections in the fire-box, thereby obviating a heretofore serious .objection to such class of inventions.
In the drawings, I igure 1 is a perspective view, the walls of the fire-box being broken away, showing the superheater and its connections in proper` and relative adjustment. Fig. 2 is a vertical longitudinal sectional view of the superheater.
a is the body of the superheater, formed cylindrically with a sag or belly b on its under side within its length, and provided with a tap or screw-plu g for the purpose of cleaning, &c.
c o are necks formed integral with the body a., screw-threaded on their inner peripheries for the reception of the screw-plug connections d d', which are also screw-threaded female to receive the steam-pipe connections.
The superheater d is located lin the upper front portion of the fire-box directly behind the crown-piece and near the upper series or row of tubes, out of the way of any ordinary use of the lire-box and in no way hindering the working of the boiler or furnace.
The side walls of the fire-box have openings for the reception of the necks c c of the superheater, said necks being peculiarly formed to admit of the easy placing and replacing of the superheater.
When it is necessary to replace a superheater or supply one to an old boiler after the holes have been made in the proper places in the sidewalls of the fire-box, the superheater is passed in through the furnace-door. The long neck c of the superheater is passed through the opening in one side of the rebox far enough to allow the other or shorter neck c to be passed into the opening of the other wall of the fire-box. These necks are securely fastened in place and the steam connections made, thus completing in an exceedingly shorttime and with the least labor a perfect superheater with no connections in the fire-box, and therefore no joints to leak, as they invariably will when subjected to the intense heat of the furnace.
When the engine is to be put in operation and a fire started in the furnace,water is let into the superheater through the steam connections e from the boiler f, a valve g being provided,"thus having a circulation through boiler f and superheater a. When the water in the superheater has attained the proper degree of heat and has become vaporized, the valve g is closed and the steam is allowed to pass through connections, such as 71 to the engine after being dried and superheated by means of my invention.
It is well known that when an engine is a long `distance off from the steam-generator (or batteries as in my case) the steam becomes more or less cooled and therefore condensation takes place, the steam losing its force, also that when foul or muddy water is used for feed-water the boiler foams and has on its surface a floating foreign substance which passes out with the steam, so that this foreign substance together with the saturated steam passes to the engine, ruins the valves, and the water from condensation reaches the cylinder, which frequently causes much damage, blowing out the cylinder-head, endanering life, dac. Now with my improved superheater I not only dry the steam, increase its power and temperature for the long-distance conveyance, but also trap the foreign substance, which may be drawn off from the bellied portion of the superheater made for that purpose, and thus avoid the foregoing objections.
Having thus fully described my invention, what I claim is l. In asteanrboiler the combination of the superheater having supporting-necks, one being longer than the other and integral with IOO the body of the superheater, openings in the Walls of the fire-box of the furnace for thereception and support of said superheater sub; stantially as described.
2. A superheater cast in one piece in combination with the integral necks, one being longer than the other, and connecting screwplu gs in said necks substantially as described.
3. In a steam-boiler the combination of a superheater located in the forward and upper portion of the fire-box, having supportingp necks, one longer than the other an enlarged or belly portion in its bottom and means for cleaning same substantially as described.
4. In a steam-boiler the combination of a I5 JOHN IV. CASEY.
