.JPECIFESATION forming part of Letters Patent No. 339,100, dated March 30, 1886.
Application filed July 2, 1885. Serial No. 170,453.
To all whom it may concern Be it known that I, EDWIN J. HOSKINS, a citizen of the United States, residing at Ans tin, Cook county, Illinois, have invented certain new and useful Improvements in Steam- Paeking, of which the following is a specification.
My intention relates more particularly to that class of low-pressure steamengines in which the fire-box and flue are placed inside of the boiler; and the object of my inventionis to make a simple and secure packing that will prevent the escape of steam at the joint where the flue of the fire-box emerges from the shell or case of the boiler; and it eonsistsin the features of construction hereinafter described.
The drawing represents the upperportion of a low-pressure steam-motor enginehaving the fire-box and flue on the inside of the boiler, like that shown and described in Letters Patent of the United States No. 310,387, of January (3, 1885, to Henry Davey.
A represents the boiler; 13, the internallylocated flue from the fire-box; G, the point of contact between the shell of the boiler and the flue; D, the packing; E, a ring around the flue; F, flanges on such ring; G, bolts for attaching the flanges to the shell of the boiler, and II the smokestaek of the boiler.
In making and applying my improved pack ing I take such a low-pressure steam-motor as is described and shown in Letters Patent of the United States to Henry Davey, No. 310,387, of January 6, 1885, asan initial or starting point. I place the fire-box and flue on theinside ofthe boiler, so that they will be surrounded by the water. In order to make the connection be tween the flue and the shell of the boiler at the point where the shell extends out from the (No model.)
annular space above mentioned. The flanges on this ring are connected with the shellof the boiler by bolts, as shown. I prefer that the shell of the boiler just above the point of contact with the flue and thelower edge of the ring E should each slant or flare somewhat away from the flue and toward each other, the one upward and the other downward, so that the space forthe packing when the parts are together will be wider next the line than away from it, so that as the ring is forced down by the bolts it will tend to press thcpacking more firmly and securely against the shell of the flue. The same result in a less degree will be secured if only one of these parts flares, or if neither of them does; but Iprefer them both to flare. The smoke-stack H fits loosely around the upper portion of the flueD,\vhich extends above the boiler shell or case and rests upon the ring E, so that it is raised and lowered as the ring Eis raised and lowered. By this arrangement the flue can move up or down in the smoke-stack as it expands or contracts independently of the sniokestack. By screwing the flanges further down from time to time as may be needed, thepaeking will be more firmly and compactly pressed against the shell of the flue. By thus making this riugadj ustable the packing may be pressed tightly or loosely against the line, as desired. Atthesametime the flue will be permitted to move upward or downward in its position as it may be required to do as it expands or contracts. In this way I secure a perfect, simple, and securely-packed joint that will be both water and steam tight between the shell of the boiler and the flue.
\Vhat I claim is- 1. In a steam-boiler, the combination ofan internal fire-box and flue, asurrounding boiler shell or case, a packing in the annular space between such shells where the flue-shell extends out of or above the boiler-shell, and a ring around the flue-shell, on which ring the smokestack is placed and rests, extendinginto such annular space and adjustable up or down, pressing the packing with more or less tightness against the fiue-shell, as desired, whereby the joint between the two shells atthe point where the flue-shell emerges from the boilershell is rendered steam-tight, and the flue-shell allowed to move up and down as expanded or contracted, substantially as described.
2. In a steamboiler, the combination of an internal fire-box and flue, asurrounding boiler gether, and a packing in the annularspace between the boiler and the flue-shell, and packed with more or less tightness against the flueshell as the ring is adjusted up or down,where by the joint between the two shells at the point Where the flue-shell emerges from the boilershell is rendered steam-tight and the flue-shell allowed to move up and down as expanded or contracted, substantially as described.
