SPECIFICATION forming part of Letters Patent No. 704,753, dated July 15, 1902.
Application filed November 23, 1901. Serial No. 83,420. (No model.)
sylvania, haveinventedanew and usefuljIm' provement in Steam-Boilers, ofwhich the following is a specification.
My invention 'is an improvement in steam boilers and relates particularly to the construction in and adjacent to the fire-box; and the object of my improvement is to provide a simple, economical, and durable form of strengthening bolts and plates for staying the sides of the fire-box and boiler.
WVith this object in view the invention consists in the peculiar construction and novel combination and arrangement of parts, as will be fully described in the following specification and pointed out in the claims, reference being bad to the drawings, in which Figure 1 is a diagrammatic longitudinal sectional View of the fire-box end of a boiler. Fig. 2 is a cross-section taken on about the line 2 2 of Fig. 1. Fig. 3 is a detail perspective View of one of the staying-plates, and Fig. 4 illustratesa modified form of angleplates. I
My invention is particularly applicable to boilers wherein the fire-tubesor lines are so arranged that the ordinary stay-bolts are impracticable, and in applying my improvement I have shown an ordinary steam-boiler A, having the fire-boxB arranged in one end thereof, the forward portions of the sides of the box extending up past the lower edge of the boiler, as shown at B, where it is braced to the outer shell of the boiler by stay-bolts B B The rear part of the fire-box also has a series of stay-bolts B as shown most clearly in Fig. 2 of the drawings.
In the end of the boiler that projects into the fire-box Iarrange a series of stay-plates 0, comprising a body portion 0', whose ends are bent downwardly, forming short flanges, as shown at G which are securely riveted to the sides of the boiler-casing, and in order to provide a further means for holding the plate I provide each plate at their flan ged ends edged riveted to the said stay-plate and the opposite edge cl securely riveted to the boilerca'si'ng. These plates are intended to pass :between th'e'flues, as shown, and I have found from apractic al application of them that a inost satisfactory result has been obtained,
and they can be used where it has been found impossible to place the ordinary stay-bolts.
It will of course be understood that any number of plates may be used as the 0ccasion may require; but ordinarily thennmber shown in the drawings will suffice.
I may find it desirable to form thefianges of an entirely separate piece from the stayplates, and in that case I arrange T-shaped plates E, as shown in Fig. l, that are secured to the boiler and to each of which are connected the stay-plates C; The result in this case is practically the same as that shown in Fig. 3 of the drawings.
Havingthus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In a steam-boiler, the combination of a boiler, having'one end terminating in a fireboiler, the said plates having their opposite ends bent downwardly to form short flanges,
and angle plates having one edge held to the plate, the opposite end being arranged for engagement with the sides of theboiler, substantially as shown and described.
2. In a steam-boiler, the combination of a boiler having one end terminating in a firebox, tubes arranged in the boiler, angleplates arranged upon the inner surface of the casing and adjacent the tubes, plates interposed between the tubes and having their ends connected to the said angle-plates, and stay-bolts connecting the inner shell of the fire-box and the casing of the boiler, substantially as described.
