forth in the following specification.
This invention relates especially to a method of constructing and assembling the boiler tube and the inner circulating tube of multitubular steam generators.
According to thls invention no portion directly subjected to steam pressure is screw 1 threaded and the tubes are assembled and the boiler tube closed exclusively by conical metallic joints, the tubes remaining easily removable, balanced and independent.
The boiler tube and the inner tube are so assembled that the head of the inner tube forms a plug to the boiler tube and such plug may be maintained in position by means of a member so mounted as to prevent the head or plug from being blown out by steam pressure. A safety bar may be provided to maintain two neighboring boiler tubes in the collector of the generator.
The accompanying drawing illustrates one method of carrying out the invention.
In this drawing Figure 1 is a front elevation of two boiler tubes mounted upon a collector; Fig. 2 is a longitudinal section on the line A-A of Fig. 1; Fig. 3 is a section on the line 13-13 of Fig. 1; Fig. 4: is a front elevation of the plug closing the boiler tube; and Fig. 5 is a front elevation of the cover which aids in preventing the plug of the boiler tube from being blown out.
Each boiler tube a is fitted to the collector Z) in the known manner, the metal joint between the two parts being kept tight by two swells c and d formed at the head of each boiler tube. Such tubes differ however internally from the usual construction.
0 is an inner circulating tube for heating the feed water and is provided with an enlargement c which fits into the narrowed portion a of the boiler tube.
f is a stirrup which connects the inner tube 6 through a rivet g to a head or plug h which closes the boiler tube a. The tube a is internally coned at a and the plug 72. is externally coned, the conical portions hearing one against the other. When the plug 72. is placed in the boiler tube as shown in Figs. 2 and 3, a cover 6 mounted upon its screw threaded rod j is placed in the boiler tube by Specification of Letters Patent.

. passing the projecting parts i i on the cover 1 through the corresponding holes 7c 70 formed :in the boiler tube. The cover is then given about a quarter of a turnin the proper di- -rection in the head of the tube a so as to 1 bring the projections z" z" beneath the flanges Z l of the tube; rotation is discontinued when the stops 2' i on the cover bear against the ends of the flanges Z Z. The screw j is turned by means of a suitable spanner, its end 7" bearing against the plug, until the plug is tight within the tube. V
The plug 72. is provided internally with 'be withdrawn from the boiler tube with the greatest facility by the aid of any suitable tool bearing for example both internally against the flanges m m and against the end of the tube. The flanges Z Z serve in the same manner to withdraw the tube a, from the collector 7) by the aid of any suitable tool which takes a bearing for example upon the flanges Z Z and upon the external face of the collector.
'n is a safety bar which bears against two neighboring boiler tubes 0; and maintains them in the collector b by the aid of a nut 0 which screws upon a rod 72 mounted upon the collector. The bar a is guided by the rod 79 and its fingers a engage in slots i in the cover 71 and thereby prevent undesired movement or rotation of the said cover on the threaded rod or screw j, said fingers a thus constitute means for holding the rod-supported member consisting of the plug it and the stirrup f united therewith.
