HEATER.

SPECIFICATION forming part of Letters Patent NO. 724,511, dated April 7, 1903.

Application filed April 12, 1902.

To all whom it may concern:

Be it known that I, ALFRED Sonii'rr, mechanical engineer, a subject of the Emperor of Germany, and a resident of No. 19 Pestalozzi street, Oharlottenburg, in the Kingdom of Prussia and Empire of Germany, have in: vented certain new and useful Improvements. in Heaters, of which the following is a specification.

The present invention relates to' an improved construction ofa vaporizer, by means of which smallest possible quantities of liquid may be spread over the largest possible heating-surface. As a matter of fact it may be stated here that efforts have been made to solve this problem by evaporating liquids in a pipe, as in the case of Serpollet; but such forms of execution are suffering from the drawback that in so narrow a space the de-- velopment of steam cannot take place'in a uniform and quiet manner. Now the present invention is adapted to solve this task in quite satisfactorya manner by creatinga construction which combines the advantage of vaporizing the fluid spread outin a very thin layer (irrigation) with the advantages granted by an ordinary large-surface steam-boiler.

In the accompanying drawings, Figurel is a vertical section of the entire irrigationevaporator. Fig. 2 is a vertical section of a heating-tube in same, and'Fig. 3 a top view of said heating-tube. v

Similar letters refer to similar parts throughout the several views.

In the represented form of execution, a is a cylindrical vertical boiler, and b b its bottoms or ends, between which tubes kare spannedfor instance, strongly rolled in. The bottoms are provided with domes c and c, the lower one, o, of which is divided into two parts by a partition Z. The steam or hot gas intended for heating the device enters from the socket d, passes'through the tubes 7c,-situated at the left-hand side of the partition Z, in a perpendicular direction from bottom to top, thence in the opposite direction through the tubes 70, situated at the right-hand side of the partition Z, and escapes through the socket e. The fluid to be evaporated comes from outside the tubes and is designed to run down along the tubes and to evaporate at the same Serial No. 102,578. (No model.)

time. For such purpose the boiler is pro- .vided with horizontal partitions or bottoms over the top partition f, and runs down along y the tubes 76. Those parts of the liquid which,

in the case of the boiler being considerably strained, fall down freely instead of running down along the tubes will reach the second partition f of the boiler of exactly the same arrangement as the first one, when they will be compelled to go onrunningdown. If the size of the boiler be proportionate to the effect it is to take, the whole of the liquid will be vaporized before it reaches the last partition; otherwise any not vaporized quantity of liquid will accumulate on said last bottom, from where it may be drained oif through the socket h. The steam or vapor maybe taken off in .difierent manners, preferably, however, through a collecting-pipe i, which tightly passes through all the bottoms f f f and whose parts contained between two successive bottoms are perforated for the purpose of permitting the steam produced by the evaporating liquid to get, as shown by the arrows, into the collecting-pipe i, whence they may be drawn ofi and led upward.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. A heater comprising a boiler or shell, with upright heating-tubes therein, while the space surrounding said tubes forms a chamber which contains a fluid to bevaporized and the vapor produced therefrom, a horizontal partition located within the shell and having apertures through which the fluid may pass from one side of the partition to the other, and an upright collectingpipe which extends through the said partition and has vapor-receiving apertures both above and ICO 2 want below said partition, the upper end of said the fluid to be vaporized may pass from above collecting-pipe extending through the top of the partition to below the same, and the shell the shell to the outside thereof. being provided above said partition with an 2. A heater comprising a boiler or shell inlet for the fluid to be vaporized. 15
