To all abomttmay concern:

Be it known that I, CHARLES WILLIAM Zasrnow, a citizen of the United States, residing at Arundel Cove, in the count of Anne Ar'undel and State of Maryland, ave

- and combination ofinvented certain new and useful Improvemen-ts 'in Evaporating'Ap aratus', of which the following is a speci cation, reference being bad therein to the accompanying drawing. V I

This invention useful improvements in apparatus for evaip ora-ting or distilling water or other liqui s, and has for its principal object to provide an apparatus which. is particularly adapted to-heused at sea for evaporating salt water.

A further object of the invention is the provision of an a paratus which will be simple in constructron, and one which may be easily cleaned and readily accessible in case'of repairs.

A still further object of the invention is the provision of an apparatus which will.

effectually prevent any traces of salt water being carried into the upper part of the eva crating still.

Vt ith' these and other objects in view, the invention consists of the novel construction scribedand claimed.

In the drawings :Figure 1 is a vertical section through. an apparatus embodying my present invention, some of the steam coils being removed. Fig. 2 is a cross sectional view thereof taken on the'line 22 of Fig: 1, and 'Fig. 3] is a similar view taken on the line 3-3 of Fig. 1. I

. In carrying this invention into practice I preferably make use of acasing or recepjtacle 1, which in the present instance isin the -form of a vertically arranged cylinder,

the same'being closed at its to and bottomor compartment. In this connection t is relates to" certain new and" parts hereinafter (le 'to be noted that in devices of this character where the heating coils are immersed, foammg 1s liable to occur in the evaporator, and

.i if such does occur, the baflie plates will break upethe globules of steam and water and the 11 rated steam may then pass to the steam space above the plates and then to the condenser without carrying traces of salt water. The heating medium used in connection with this apparatus is preferably steam, the

same" being fed through a pipe 7, passing through a suitable stufiing box '8 centrally arranged u on the head 2 of the cylindrical casing. T is pipe is arran ed longitudinally of the casing and is cei itrally located therein, the same extending through the perfor'ated bafii'e plates and into the water compartment, and being connected to an upper manifold 9 by a pipe 10' which is arranged at a right angle to the inlet pipe. A series of coils 11 connect' the upper manifold 9' with a lower manifold '12, which manifold '12 is connected in any. suitable manner to an outlet pipe 13. The outlet pipe 13 is also arranged longitudinall of the cylindrical casing and centrally ocated with regard.

thereto, the same passing from the water compartment througha stuffing box' 14 on the casing. In this manner live steam is "lied from a suitable generator to the steam heating coils 11, which coils serve to thoroughly heat the water within the compartment i and generate steam, whichsteam rises and passes through the perforations in the baffle plates and is collected within the compartment 5 from which itcscapes through the outlet pipe 15 and is led away to any suitable form of condenser in which it is condensed into purified water or other liquid, according to the class of work which is being performed.

A suitable gage 16 is provided for the purpose of determining at any time the amount of water in the casing, and a steam gage 17 is shown in dotted lines and serves to indicate the steam pressure occasioned by the steam generated in the casing. ll also provide a suitable safety or blow-oif valve for'the steam compartment, the same being indicated at 18in dotted lines, and a blowoff valve 18 arranged in the lower manifold for a urpose which will be obvious.

In t epractice of my invention the water or other liquid to be purified o1; evaporated is carried into the water compartment through'a pipe 19, and the same is converted .into 'steam. in the manner heretofore described whereupon said steam is conveyed from the casing and condensed into purified liquid. The heating apparatus used for gencrating this steam, as will be noted, has an inlet pipe and an outlet pipe which are cen trally located within the casing, said piifipes passing through the upper and lower stu ng boxes as heretofore described and being adapted to turn within the same, so that the heating apparatus as a whole may be revolved upon its vertical axis to facilitate the cleaning and scaling of the salt and other defects which have been deposited on the heating surface. A suitable door is indicated at 20 which closes the opening in the side of the casing, and it will be readily understood that any one of the heating coils 11 may be brought opposite the opening when it is desired to clean the same, thus obviating the necessity of removing the coils from the apparatus. It is also to be noted that any one of the coils may be taken out through this opening and another set up in its place without the necessity of disturbing any other coil. Furthermore, suitable connections between all of the parts contained. within the casing are provided, which will permit the entire apparatus being taken apart within the casing and removed therefrom through the opening in the side'of said casing. This will be perfectly obvious upon an examination of the drawing, it only being necessary to state that a coupling 21 in the inlet pipe is used so that the upper section of the inlet 'pipe may be disconnected and withdrawn through the top of the casing; and a coupling 22 is used for the outlet pipe which al lows the ipper section thereof to be lifted within the casing and withdrawn through the opening in the casing.

It will therefore be understood that I ac complish the object of my invention by means of an apparatus which is simple in construction and operation and well adapted to accomplish the result for which it is. intended, and furthermore, the parts are so connected that they may be easily disconnected and taken'from theapparatus when necessary, and may also be easily cleaned without taking them from the apparatus.

What I claim is 1. An evaporating apparatus, comprising a casing or receptacle having liquid and steam spaces therein, an opening within said casin asteam inlet pipe centrally located therein and journaled upon said casing, a steam outlet pipe also journaled upon the casing in line with the inlet pipe, stulfing Witnesses:

boxes for'hoth of said journals, and steam as heating coils connecting the inlet with the outlet pipe, said coils adapted to be re-- volved as the inlet and outlet pipes are rotated within their respective bearings with out releasing any of the parts or connections 5 ofthe inlet and outlet pipes.

' 2. An evaporating apparatus comprising a vertically arranged casing having liquid and steam spaces therein, an opening in said casing, a sectional steam inlet pi entering the casing at the upper end t ereof, the same being journaled u on the casing, a detachablecoupling for t e sections of said inletpipe located within the casing and adjacent the opening therein, a circular manifold connected to said inlet pi e, a plurality of steam heating coils depem ng from said circular manifold and connecting the same with a similar manifold, and an outlet pipe connected with said second mentioned maniso fold and journaled upon the casing in line withtheinlet pipe, stufiing boxes for both of said journals, the entire steam apparatus adapted to be revolved without releasing any of its parts or connections as the inlet 8d and outlet pipes are rotated within, their respective bearings, substantially as and for the purpose specified. I

3. An evaporating apparatus, comprising a vertically arranged casing having liquid as and steam spaces therein, an opening in said casing, a sectional steam inlet pipe entering the casing at the upper end thereof, the same being iournaled upon the casing, 21. detach able coupling for the sections of said inlet .95 pipe located within the casing and adjacent the opening therein, a circular manifold connected to said inlet pipe, a plurality of steam heatin coils. depending from said circular manifo d and connecting the same with a similar manifold, a sectional outlet pipe connected with said second mentioned manifold and journeled upon the casing in line with the inlet pipe, stufliug boxes for both of said journals and a detachable coupling for 1 05 the sections of said outlet pipe located outside thecasinlg, the entire steam apparatus adapted to be revolved without releasin any of its parts or connections as the inlet and outlet pipes are rotated within their re- 1 l0 spectivo bear ngs, substantially as and for the purpose specified. r

In testimony whereof I alfix my signature in presence of two witnesses.
