Specification forming part of Letters Patent No. 214,090, dated April 8, 1879; application filed January :24, 1879; patented in England, May 27, 1878.

.To all whom it may concern:

Beit known that I, JOSEPH ELTON BoTT, of Nottingham, England, have invented new and;A useful Improvements in Injector-Gondensers applicable to single or double cylinder steam-engines, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to improvements in condensers, 'and is applicable to single or double cylinder steam-engines.

My invention consists in .the combination, with the outer casin g of a condenser for steamengines, of an interiorbell-mouthed nozzle and an adjustable spindle extending through said nozzle and terminating in an enlarged or daring lower end or tip arranged below or partially within the bell-mouth of the nozzle, whereby the injectionwater which ows through said nozzle is guided into the form of an annular sheet-like jet, so that the whole of the water is brought in contact with the exhaust-steam, which enters the condenser-casing, and a rapid and thorough condensation elected; further, in the combination, in a condenser for steam-engines, of an interior waternozzle provided at its mout-h with internal ta pered spiral grooves and a conoidal or outwardly-tlaring discharge-chamber provided with similar grooves, whereby a rapid gyratory motlon is given to the injection-jet, the exhaust steam entering the easing is rapidly condensed, and the products ofcondeusation speedily carried oft', further, in the combination, in a condenser-casing, of an interior hellmouthed, nozzle having at its mouth internal spiral tapered grooves, and a spindle extending thgough said nozzle and terminating at its I'1ovv`ei.e'nd in an enlargement or flaring tip, fthe inclined surface of which next the nozzle is provided. with spiral grooves, which co-opi crate with those of the nozzle in imparting a rapid gyratory motion to the injection or condensing jet of water which ilows through said nozzle.

Referring to the drawings, Figure 1 is a verticalsectional View of my improved condenser as constructed for one-cylinder engines. Figs.

2, 3, and 4 are, respectiyely, a plan and two cross-sect1onal views of the same.

Fig-.5 is a The corresponding parts in 'each figiire are lettered alike.

The arrangement and construction of the first-named form of my improved condenser shown in Figs. l to 5, inclusive, consist of the following parts-v-that is to say: A is an outer case forming the exhaust-chamber of the condenser. B is a branch for the exhauststeam from the engine-cylinder. The condenser is shown as havingthe exhaust branch turned upward; but it may be constructed with the branch turned downward or on either side, as required. G is an injection-nozzle. C' are tapered spiral injection-grooves. D is a discharge-space to the hot-well or wastepipe. D are tapered spiral discharge-grooves. E isthe body of the Water-injection valve. E is a brauch for water from a supply-tank. F is an injection-water regulating-spimlle. Gis a lower guide for the spindle Fi II is a hand- Wheel for operating the spindle F. I is a bracket-guide for spindle. K is an air-tight gland. L represents screwed studs for adjusting the injection-nozzle. M is a divergin g disk ot spindle F. i

Fig. 2 is a plan on the line N N of Fig. 1, with the body E of the injection-valve removed. Fig. 3 is a cross-section of the condenser on the line 0 0, and lFig. 4 a cross-section on the line I l?, Fig. 1.

In Figs. 1 and 5 the arrows marked 1 show the direction of the exhaust-steam, the arrows marked 2 sliow the direction of the injectionwater, and the arrows marked 3 show the direction of discharge.`

rlhe body ofthe condenser is of cast-iron or other suitable metal, an'd has an exhaust-chainber, A, froniwhich projects an exhaust-branch, B, leading to the cylinder or cylinders of the engine to which the condenser may be attached.

Referring: to rigs. 6 und 7, the following is :i general description of the several parts: A Il is the exhaust hinnvh :ind pipoconnectingthecondenschvith thv vilituhfr ot' un engine.

S' is a bell vrztnk lcijcr for operating the steam-vulve S. s" is :i vonncctinglpipe screwed inbo a boss on t onv sidv of gnidntrsocket, T, which ischulnhvrvtl.

'l`ho nvtion nt' the condenser :tud the above vntnnvrntvtl parts is us follows-that is to say:

\\' hvn :tpplicil to n marine engine or n. windingcnginv, thv storting wheel or lever of the en- ;nv may hun: n clutch-connection with the lvvcr S', und will thus open the valve S on thc starting of the engine, and so allow steam to leave the high-pressure steam-chest and pass into the body of the condenser by the pipes S Si through thechambered socket/Pon the rcgnlntingsplndlc l", entering the sanne through thc slots or orifices und issuing with great force :is u ict through the point ot' the spindle nent' thv. divvrg'ingdisk. lhisjct ot'stemn will exlmust :dl thv :tir l'tont the exhaust side ot' thc lol pi-vssnrv piston. thus greatly nglsistiingr thesturtin.;r ot' thv cnn-incl especially those otthv ln thv inoditnuttion ot' n| iniptorvd votr dvnsvr shonn nt Fig ti to l0, invlnsuv. l"i; f.

hn'gvr ltnnls. lnuncdnttcly the low-pressure l l l and highpressure steam begins to exert its force the steam-valve S2 must be closed, either by disconnecting the lever Sl by hand or by any mechanical apparatus for automatically doing the same. Immediately the lowfpressure piston receives steam from the highfpressure cylinder the attendant will turn ou the injection-water by means of the handle R', operating the equilibrium-valve R, thereby admitting water through the nozzle C, when condensation will be effected, as described in the first modification, 'and the combined products of condensation will be discharged. into the hot-well Q and thence through the branch pipe Q.

f While I prefer to use the hollow spindle F or connection with any condenser when applied to low-pressure marine engines, it may be omitted if desired; and I do not here claim it in 1.combination with the other parts of my in volition.'

whatilaim is- L'The combination, with the-outer casing cf 'a condenser, of the bell-mouthed nozzle C and the spindle F, having the enlarged or. fiarin g lower end or top, M, whereby the injectionwater is guided into the form of an annular jet, substantially as and for the purpose set forth.

2. In a condenserfor steam-engines, the conibination of the nozzle provided with the internal tapered spiral grooves and the conoidal discharge chamber having similar grooves, whereby a rapid gyratory motion is imparted to the injection-jet, the exhaust-steam rapidly condensed, and the water .of condensation speedily carried oft, substantially as described.

3. The combination of the bell-mouthed nozzle having the tapered internal spiral grooves and the spindle having the enlarged or daring lower end or tip, the upper inclined surface of which is provided with spiral grooves', substantially as and for the purpose set forth.
