GEORGE HENRY CORLISS in PROVIDENCE (V. S. Α.). Innovations to steam boilers.

Patented in the German Empire on May 27, 187g.

The invention aims at the manufacture and arrangement of peculiar tubular boilers, which for re-evaporation of the condensation water, for drying the steam, for heating of the feed water and can be used for analog purposes.

Fig. Ι of the drawing shows a set of these tubes and their connections in part Cut, partly in the front.

Fig. 2 shows a number of such sentences, partly in section, partly in side view.

Fig. 3 is a longitudinal section and Fig. 4 is a cross section of a connecting ring. ·

Fig. 5 shows the arrangement of these tubes in the Feuerzuge vertical steam boiler.

To manufacture these tubular vessels, the ends of the tubes JI ¹ , Fig. 1, all of which have the same diameter after they have been gradually heated, are narrowed by rapid blows in their own dies. Care must be taken that the metal at the transition point h is not weakened too much, nor that it is too thick in the neck h '. The tubes are gently bent and each neck h 'is screwed into the reinforced side h ^{G of} one of the rings / z ^2. These end rings / z ² fit one another exactly and are held firmly together by means of a continuous bolt h ³ , so that they form the end chamber H ^ . The parts are put together after the tubes have been individually fastened in their rings. Here, the length of each tube can be made suitable by increasing or reducing the curvature. The various ring sets are connected to one another at the bottom by the cross tube h ' ¹ and at the top by the cross tube h ^b. ZT ⁹ is the supply pipe, U ^s the discharge pipe (see also

Fig. 5) - The inventor considers it expedient that the end chambers JT " lie firmly against the side walls of the fire flue JI ² in which they are arranged. They can rest on supports or be hung up.

The application of this pipe system to the feed water heating apparatus JI ^{7 is} shown in FIG. In this figure, H * denote vertical bowls. H * are channels which lead horizontally to forge Ή ^α . The draft H ^% made with converging walls conducts all combustion products that have passed between the boilers to the forge U ^c '. The tubes H ⁱ H ⁿ are most suitably arranged with the hollow curved side towards the forge.

The number of tubes in each set, as well as the number of sets can be chosen as desired. The tubing sets can be placed in a differently shaped heating chamber or other train. You can also use the Receive combustion products directly.

Claims (2)

Patent claims: 1. The curved tubes JI ¹ U " with narrowed necks h ', the end chambers H ° and fastening bolts h ³ , essentially as described and shown. 2. The arrangement of the end chambers H '" shown in FIG. 5 with the tubes H ¹ H ⁷ in a fire train JI ² , essentially as described and for the purpose described.
