BOILER.

SPECIFICATION forming part of Letters Patent No. 245,822, dated August 16, 1881.

Application tiled February 14, 1881.

To all whom fit may concern Beit known that I, CORNELIUS E. HAYNEs, ot' Boston, in the county ot' Suffolk and State of Massachusetts, have invented an Improve- Yment in Boilers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 is an elevation of a boiler constructedin accordance with myinvention. Fig. 2 is a vertical section through the same. Fig. 3 is a transverse section.

The object of my invention is to produce a boiler for bot water and other purposes at a much less cost than heretofore, and it consists in certain details ot' construction which will behcreinafter more particularly described and specitically claimed.

In the drawings, A represents a boiler for supplying hot water to the different apartments ot a building. This boiler, which is made ot' metal, is corrugated or fluted, as shown-to wit, from end to end in straightand parallel lines and all roundfor the purpose ot' resisting the internal pressure ot' water or steam or external pressure caused by a vacuum formed within it. The top a ot' this loiler A is provided with a flange, b, which projects down over the main portion, and is secured thereto by rivets or solder, as may be found most desirable.

The bottom c, which has a corrugated edge to match with and tightly fit into the corrugations of thepboiler, is secured to the main portion of the boiler A by means ot' bolts or rivets passing through the iiange d of the bottom c, which projects down on the inside ot' the main portion A, and it will be seen that by this construction the bottom c can easily be removed when required to make repairs, and also to obtain access to the interior of the boiler.

The rings or braces f have corrugated edges to :tit the corrugations of the boiler, and are placed upon the inside of the boiler and se- (No model.)

cured thereto in any suitable manner, for the purpose ofstrengthening the boiler when made of thin material, and also to serve the purpose ot keeping the boiler in its proper shape. In practice IV have found that by making the corrugations as shown in Fig. S-that is, one large and one small alternately-it greatly adds to the strength ot" the boilerin resisting pressure from within, and also serves to retain the boiler in its proper shape.

A boiler constructed as above described can be easily and cheaply made and is exceedingly strong and durable. Furthermore, much thinner and lighter material can be employed in its construction than has heretofore been found practicable, while it will withstand a much greater pressure outwardly or inwardly per square inch than boilers ot' the old construction.

I am aware that the broad idea ot' corrugatin g a steam-boiler is not new, and that sectional boilers have been corrugated at right angles with their length, and other boilers have been corrugated in some degree horizontally, and also some spira-ll y, and also that vinternal strengthening-bands have been used in such boilers.

What I claim is as follows:

1. The boiler A, corrugated from end to end in parallel lines, and provided with the internal annular brace, f, having a corrugated edge, substantially as shown and described.

2. The boilerA, corrugated in parallel lines from end'to end and entirelyraround, and provided with the internal annular strengtheningbrace, f, as described, and the bottom o, havin g a corrugated edge, all substantially as described. t
