To r/,ZZ 7.071071@ z'ft may concer/c:

Be it known that l', REN llnNnr, a citizen of the Republic oi France, residing at ivlontreal, in the district oi" Montreal, Province of Quebec, Canada, have invented cer` tain new and uselul improvements in Steam- (lenerators, of uh iication.

My invention relates to improvements in sten11i-generators, partieularl)A referring to the circula!ing-tubes therefor; and the object. ot' the invention is to generator cheap to manufacture, whereby the arrangement of the`tubes will facilitate the circulation oi" the water and steam in such a manner as to insure econolnjin luel and render the repairing or replacing of a tube a simple matter; and it consists. essentially, of a plurality oi' tubes having closed outer ends, om` or more heads provided with an internal passage, a pluralit)Y ot plugs extending across the said passage in alineinent with the tubes and designed to support centralljv lesser tubes open at both ends and projecting into the aforesaid tubes, suitable )lugs closing the entrances in the head or heads to eaeh open plug, and voir surmounting the tubes, the various parts being constructed and arranged ir :.le.- tail, as hereinafter more particularl) described.

Figure l isa perspective. vieu' of mygenerator, partialh in section, showing several heads joined together Iwith the outer edge Wall removed. Fig. 2 is an enlarged sectional detail of tho stopsI plugs, tubes, and portion ot" a head. Fig. I an enlarged sectional front. elevation oi' a head broken awajv'. Fig. 4 isan enlarged detail of a plug with a portion of the inner tube.

Lilie letters oi' reference indicate corre` spending parts in each ligure.

aI represents the heads, which are preferabbVA serpentine in shape, having tho passage b cored outy to the `full extent of their length.

c represents orifices leading into the passage and arranged alternately in vertical rows.

d represents Corresponding orifices from the passage b and converging slightly toward their outer ends.

, @represents tubes closed at one end and atthe other inserted into the orifices d, so as to extend inwardly thererorn. The tubes e ilare ich the following is a specii provide a quick a steain-nserl loutwardlv somewhat at their open end lo l correspond with the taper in the ori'iices d in order to -Facilitate the removal of the tubes from the head.

f represents hollow or open tubes having the diagonal partition-wall g and the orifice 7i theretlnough. The plugs f are designed to i be inserted in the orfices c and extend across ,i the passage b and enter the orifices d.

l y' represents inner tubesl open at both ends t and supported in the central orifices h of the f plugs f and extendingr into the tubes e in proximity.' to the closed end.

1r represents solid plugs, preferabl') threadl ed and screwed into the orifices c. l is a steam-reservoir above the tubes e in l the heads a, communicating from head to l head and suitabl) cLosed at each end. l m is a tie-rod extending through the steamireservoir and designed to hold the several heads (1 securely together.

It must be here understood that in the outg sidel heads the closed end ot' the reservoir I* Ina-v be solid with the casting or provided with removable cover-plates.

4 'n represents feed-pipes leading troni a comi mon iced into the various heads at their lowl ermost ends immediately beneath the boti tom tube.

Having described the various parts in detail, I shall now more particular-l)r explain the device in operation. The water is turned on into the-common feed-pipe and branches oil' into the several feed-pipes ln, filling the lowermost end ot each head a, and, continuing its flow, passes through the inner tube j, the mouth ol" the latter being ilush ith the partition-wall g. The 'flow continuing, the Wa.- ter passes out. oi the inner tube and is turned backwardl;Y by the closed end oi theouter tube rf. The stream non'. finding a passage between. the outer and inner tubes, flows on in its return until its course is obstructed. b v the artition-wall g, the latter turning it upwardly, where the Wall g again provides an obl ll struction from its under side, the Water `finds an opening in the orifice h, lee-ding to the inner tube next above' the one. it hasl been through. The further assage up the series of tubes is. similar verse osition, closing vthe opening beneath into t ie inner tube, and

until within a certain nurnber of the top, when the plugj is placed 1n rethus directing the steam vlnch has been generated trom the IOO water into the outer tube first und returning the seme throuffh the inner tube to pass throueh the orihce it, which hes been cony verte@ from :in inlet to en outlet by the reg versel of the plugf.

lt will be seen from the foregoing' lcscription that the position of the pertition-wnll is the mein feature in the .reversal ol the circoletion, for the mere turning; around of the plug a half-turn from its irst position prethe tubes, :is lully explained in the foregoing.

sents on the lower side n passage outside the i inner tube instead of into it--thet,is, the perti'tion-lvvell and the inner tube serve to guide l the steam or Water into the outer tube.

The plug r is rmly screwed into the orifice l c and sbuts the outer side of the plug f to hold the letter securely in the position desired, and ss the opposite end of the lug shuts the edges of the casing of the tu )e c the latter by reason of its flaring ends zigeinst the tapered orifices d is held iirmly in place.

The removal 0l the various parts for replacing or repair is u very salient feature in my device. F or inst-ence, on the removal ol` a plug lr the lugfmny be drawn out., carrying With it t e inner tube The oriice is then free, and theI tube e can be removed with ease, for the Haring open end ci the tube 'shuts the converging portion of the orifice. The Withdrawal ot thc plugf removes the pressure on` the end of the tube, leaving it comparatively loose in the orifice to be teken out.

It must be understood thzitl do not conl'ine myself in construction to this ltapered joint, es many other ways may be adopted equally eliicacious.

The position of the tubes makes it impossible for the combustible properties from the tire to rsscend in my but t tortuous psssege, thus securing the hill advantage of n large heating eren.

The reversal of the plugs lending` to the upper tubes is for the purpose. of superheeting the stes-m, and though it cannot be :iccuretely stated, yet it is supposed that the Wnter is flashed into steam very soon after entrance'.

rllhe application ol' this system of circulating-tubes need not necessarily be confinedv to s generator, as illustrated, it will be reedily understood that it may be used in en ordinary Water-tube boiler, or for radiators, or in fact, in any case where such circulation is a necessity.

'l have shown in Fig. l the steam; pipe o fromI the Yend of the steam-reservoir i', 'Wherees in Fig. 3 l have shown the seid T ipe from s different point end have replace it with n, pipe p in order to explain more clearly the conversion of the generator as described from e flash-boiler to en ordi-nary Waiter-cir enlisting-tube boiler.

instead ol' further illustration a few Words will explain that thet introduction or" my cir I liet.

ln further reference to the adoption ol'` my circulation-tubes l may mention that'the facilities provided for easy repair and the certainty ol' :i perfect circulation in nach series multe this system very valuable for hot-wc ter furnaces used in heating houses by ges, for ammonia-condensers, for ice and-refrigereting plants, particularly as to the elimination of the joints, for surface condensers for condensing-engines, for feed-water heaters, for serpentine for alcohol distilleries and breweries, rendering it easy to clean 'the tubes inside,l\vhich is new impossible.

Another point to emphasize in my generetor inthe advantage of passing the Waterirst through the inner tube in entrance, sind thus' heating it before it comes in contact With the outer tube.

A suitable valve is necessary for the feed' where this generator is used for other than stationery engines in order to insure the regularity ol' feed to the several heads; -butes such is of necessity e seperate application I shell not gc into further particulars herein more th en merely :mentioning that for marine purposes my generator will not fail thropgh Went of a proper feed.
