STEAM surnnnnnren,
Application filed November 4, 1924, Serial No. 747,721, and in Germany January 30,1924.
This invention relates to a superheater,
and, more particularly, to that type of superheater in which two semi-circular coils are housed in an annular chamber usually, in the case of locomobile, locomotive and similar boilers, Within the smoke-box.
It is a well-known practice to locate a superheater in the smoke-box of a locomobile or locomotive boiler and to direct the flue gases from the boiler through the superheater, through a front inlet opening atthe top and a rear outlet opening at the bottom of the superheater chamber, by closinga centrally mounted damper. As heretotore constructed, however, it has been impossible to provide any means for closing the inlet and outlet openings of the superheater chamber.
The object 01. my present invention is to obviate this defect; and this end I have at-' tained in my new superheater by providing control means whereby the combustion gases may be positively directed from or to the boiler either wholly through Y or wholly its inner endto the boiler and to its outer end is fixed the endplateb which is fitted with a door 5 removably secured thereto by the usual turn-buckles or the like, having formed therein a centrally located passage 4 for the exhaust gases. Vithin the smokeboX, the superheater 3, comprising two semicircularly disposed coils, is mounted on the smoke-box walls in the annular chamber which is formed by these walls and an inner and controlled from outside the casing. The cyllndrlcal wall 6 is provided at the top, on the boiler side of the transverse wall,
'with the opening 11 which is controlled,
from without, by the two dampers 11 and 11 mounted therein and which serves as the inlet opening to the superheater chamber and at the bottom on the exhaust side of the transverse wall with a corresponding outlet opening ,10 which in like manneris controlled by the similarly mounted dampers l0 and 10?. 1
-Thus, when the dampers 10 10 and 11 11 are open and the damper "9 is closed all the flue gases from the boiler will pass through the superheater on their way to the exhaust. It, on'the other hand, the
positions of these dampers are reversed so as to close the openings '10 and 11, and open the opening 8,;the flue gases will flow di reotly from the boiler to and out through the exhaust. And by suitably manipulating the dampers a greater or lesser part of'the flue, gases, as desired, can be directed I the purpose of cleaning, adjustment, or re- It is evident that my improved superheater may alsobe used, without substantial change, in connection with boilers'of the type in which it is desirable to so locate. the superheater that the combustion gases can be passed through it before passing through the boiler. I
WVhat I claim as new, and desire to secure by Letters Patent, isf

A steam-superheaterI ot the type described comprising, in combination with a casing provided with inlet and outlet openings for the passage of combustion gases and with two semi-circularbanks of superheater coils mounted therein, an inner wall which extends from end to end of the casing within the superheater coils and dividesthe interior of the easing into an outer superheater chamber and an inner, central passage, openings in the inner wall which are located at or adjacent one end in its upper are adapted to open and close said openings in the inner wall and the passage therethrough between the openings, whereby the combustion gases may be directed from the inlet to the outlet opening of the casing wholly or in part either directly or through the superheater chamber.

3. A steam super-heater of the type described comprising, in combination with a cylindrical casing provided with inlet and outlet openings in its opposite ends and having two semi-circular banks of superheater coils mounted therein, an inner cylindrical wall which is adapted to be inserted into and to be withdrawn from the casing and when in placetherein divides the interior thereof into an outer annular super-heater chamber and a central passage in communi cation at oneend with the inlet opening and at the other end with the outlet opening of the casing, which is provided with openings located at one end in its upper side and at the other end in its lower side between the "two banks of coils, and which carries damwhereby the combustion gases may be directed from the inlet to the outlet opening of the casing wholly or in part either directly through the central passage or through the two banks of coils in the surrounding superheater chamber.
st. A superheater of the type described, comprising a casing with outer and inner cylindrical walls forming an annular cham ber closed at both ends and a central passage open at one end for the admission and at the other end for the discharge of the combustion gases, a superheater coil mounted within the annular chamber, a transverse wall within the inner tubular wall approximately cylindrical wall on the outlet side of the transverse wall, and means controllable from outside the casing for opening and closing one at least of said top and bottom openings.
5. A superheater of the type described, comprising a cylindrical casing with end walls each of which has a circular opening therein, a circular doorplate provided with central opening which fits the opening in one of the end walls of the casing, means for removably securing the door-plate in place within the said end wall opening, an inner cylindrical wall which is rigidly secured to the inner ace of and is removable with the door-plate and which when the door-plate is in position extends the length of the casing and at its free end abuts the other end wall thereof, superheater coils which aremounted on the casing within the annular chamber formed by its walls and the inner cylindrical wall, a transverse wall which is carried within the inner cylindrical wall substantially midway of its length and has a centrally located opening therein, means controllable from outside the casing and removable with the wall for opening and closing the said opening therein, openings which are formed in the inner cylindrical wall at one end in the upper side and at the other end in its lower side, and means controllable from outside the casing and removable with the wall tor opening and closing at least one of the said openings therein.
6. A steam superheater comprising, in combination, a cylindrical casing adapted to be attached at its inner end to the end of a boiler in communication with the'ga s-circulating system thereof and having in its outer head an opening for the passage of furnace gases, an inner concentric cylindrical wall which divides the interior of the easing into an inner central passage surrounding the opening to the boiler and connecting the same with the said outer opening and an outer annular chamber, two semi-circular banks of superheater coils mounted within the outer annular chamber one on each side thereof, and means controllable from outside the casing for closing or partially closing the said central passage intermediate its ends and for opening communication between the central passage and the annular chamber on the upper side at one end and on the lower side at the other end thereof. v
