GUSTAF ARVID ANDERSON, OF WAYNESBOROUGH, PENNSYLVANIA, ASSIGNOR TO THE GEISER MANUFACTURING COMPANY, OF SAME PLACE.
BOlLER.
SPECIFICATION forming part of Letters Patent No. 536,058, dated March 19, 1 895.
Application iiled December 1,1894. Serial No. 530,612. (No model.)
To a/ZZ whom it may concern:
Be it known that I, GUs'rAE ARvID ANDER- soN, a subject of the King of Sweden and Norway, residing at Waynesborough, in the county of Franklin and State of Pennsylvania, have invented certain new and useful Iniprovements in Boilers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to steam boilers and more particularly to those boilers used for traction or road engines; and it consists of a protector for the crown sheet, as hereinafter fully described and claimed, for preventing` the water level from becoming lower than the 1(rilwn sheet when the engine is going down In the drawings: Figure lis alongitudinal section through a boiler provided with a crown sheet protector according to this in. vention. boiler taken on'line 0c asin Fig. l. Fig. 3 is a 1similar cross section taken on the line y y in The boiler is of ordinary approved construction, and A is the crown sheet of its fire boX. The line h o indicates the ordinary water level when theengine is on level ground, and the line c c indicates what the water level would be if the engine were proceeding down a hill and the protector were not used.
In order to protect the crown sheet from being uncovered and burned by the heat ofthe fire in the lire box a steam chamber B is provided. This chamber B is supported inside the barrel of the boiler, over the tubes, by brackets B or any similar fastening devices which will secure it in position. The upper part of the chamber B is preferably curved to conform to the shape of the top part of the boiler but its exact form is not material. The bottom portions b h of the chamber B are substantially iiat and incline upward longitudinally toward the smoke box end of the boiler to conform to the inclination of the top row of re tubes.
A channel O is formed longitudinally in the 5o under side of the chamber B, the bottom plate being bent upward to form the sides and top Fig. 2 is a cross-section through the.
of the channel. This channel is narrow at the smoke box end ot the boiler and becomes wider as it approaches to tire-box end.
D is a head forming the rear end of the chamber. E is a head which forms the front end ot' the chamber, and is provided with a lip c having one or more openings c at its top which is near the top of the boiler.
Fis a conical ring secured to the upper part of the rear end of the chamber and projecting through a hole in the shell of the boiler into the steam dome f. The ring is made to tit the hole tightly,but au absolutely steam tight joint need not he formed between the parts.
G are drain pipes projecting from the head D and extending over the lire box.
Asingle longitudinal channel arranged centrally of the'chamber is preferred, but more than one channel may be used if desired.`
lVhen the engine proceeds down hill the water level is changed and becomes as indicated by the line d d in Fig. 1. The flatbottom portions b b of the chamber incline laterally in opposite directions at the sides of the central channel, the inclination being downward from the channel towardrthe shell of the boiler. The water presses against the bottom portions ot' the chamber and is forced forward onto the crown sheet which does not become uncovered. The steam formed in the boiler over the tubes rises against the iuclined bottom portions h h and passes into the channel C, the inclined sides of which permit it to escape freely into the steam space over the crown sheet, so that priming does not occur.
The steam passes downward through the openings e in the head E, through the chamber C and upward into the steam dome, whence it is conducted to the engine through a steam pipe in the ordinary way.
Any water which may pass into the chamber C with the steam collects in the bottom part of the chamber and is discharged through the drain pipes Gr when the engine commences to go up hill.
What I claim isl. The combination, with aboiler, of achamber provided with a head at each end and a longitudinal channel in its under side, ar-
IOO
ranged in the barrel of the boiler, and operating to prevent the Water from leaving the crown sheet, substantially as set forth.
2. The combination with aboilerof a chamber arranged in the barrel of the boiler and provided with a longitudinal channel in its under side, a steam outlet ring projecting through a hole in the boiler shell into the dome, and a steam inlet opening near the top of the chamber, substantially as set forth.
3. The combination, with a boiler, ofa chamber arranged in the barrel of the boiler and provided with a longitudinal channel in its
