To ZZ whom it "may concern:
it known that l, iiEsMnNN LEMP, e
citizen of the United States, residing at folio-Kine is e s aecilicotion.
This inve tion relates to condensers for steam engil es, end has been especielly designed for steam automobiles, in which aircooled. surl'scc condensers are 11sec. As 01*- dinei'ily constiucted, such a. condenser com- Qrisess large numb-er of tubes of smell boreconnected in multiple between two headers. Sometimes is o 01' tln'ee'of these units are out in with each other. To enable the tubes to cleaned by s cleaning red, the 11" be provided. with removable "plugs specs. the ends of the tubes, or else with e plate that can be takenofl' to give access to the tubes. 7 ln eithea' a, large number of screw slugs or screw bolts'must be t ken out. in the operation 01" stcsim mitoi'nobiles, there is great llifliculty in sepe- Yeti? one lob-electing oil li'oin the steam, so tbecomlenscr soon clogs up with oil and gfecse, end when. the steam is very not this deposit is liable to cez'booize. This makes the cleaning of such a condenser a very dise reeeblo and dirty piece o'l'wol lc, and. one wish the owoer of a. steam ceriisge would. not wish to nndezfteke lii inseli'. In addition to the u'npleessntness off tbs job, it is a testeady Work to complete it. I
The objectol' niyin'vention is to simplify the construction of condense)? of this type, and render it easy to clean when clogged up. in. close of e longs number of small tubes in mu tiple, use 1*. few tubes of larger bore, provided with redietin gills like those used in the radiators of gem-so ene motor cars. l have preferably three tubes, each bent in zigzag 'iomn the some plane and connected at each end to a smell header. The three units are pieced parallel and their sevei'el len 'tlis see steggesesl to give it better cooling eflect.
lions one, i'equii'ing fi foni one to two llsys 'TilQfiXlllUSl} steam is introduced at the top end the 101 of condensation is carried off bottom. bio circulation pump 1s needed, es the back pressure from the engine sufficient to toe-Which deprives it of most of its oi and catering the condenser, the
gTeese. When the condenser is to be cleaned, two of the units are shut oil by moons of specially designed. pin s, and live steam is llllflllitfi-ClflOl'il the boi e1, thereby thoroughly blowing out all cocomulctions from the unit that is left open. By shifting the plugs, eech unit can be blown out in turn. The operation is speedy and of such a. character that any automobile owner can readily Lmderteke it. In the eccompcnyiog drawing, Figure 1 is e (licgminnietic View of on engine, flesh boiler, Water tank and condenser with the necessary plying, valves, etc. to constitute a COh'lPlBlB system; Fig. is at front elevation of the condenser on e lsrgei scale; Fig. is
on end View of the some; and Fig. 4*. is ssectionel View of one of the headers showing the cleaning plugs in position.
The engine It is .of any suitable construe time, and is shown connected by a, chain 2 with e sprocket 3 on the driving shaft 4. of an sutomobile. A pump 5, driven by the engi'ce, supplies water from o. tank 6 to a. boiler 7, also. oi any suitable construction, though preferably :1 flesh boiler. Steam is ask-en from the boiler to the engine through a main 8 controlled by e throttle Valve 9. 7' The exl sust steem posses Efrem the engine through the pipe 10 to on oil sepcrstor 3.1, of any suit able GQDSbKUGlliOEQ, and thence to the condenser 12, Whose lower end is connected bye pipe 13 With the water tank.
The condenser is composed of two headers 14 and a cochlear of tubes 15 connected 51 161- to in multiple. The preferable number cl tubes is-three, since a. condenser of: this close must not be too deep from front to back, in order to pemnit a. good circulation of air. Each tube is of fairly good. size, say threefourtlis of so inch in. dieinetei', and of such length cs may be IIGGLlBll to make the desired size of condenser; preferably about twenty llx e or thirty feet. l lac-1 tube is bent in e Zigzag fashion in the same plane, making preferably six and a hell return bendsv From end. to end' the tube is covered with radial gills i6, and at eschcnd it has it flange 17 to enable it to be attached to e. short branch or neck 18 on the header, by means of e gland 15%.
The short branches or necks 18 are met embly three in number and staggered. as shown, so that when the tubes are connected. thereto the corresponding bends in adjacent units do not lie in the some l'iorizontel'plnncs, I but coine opposite the spaces bet ween them. Opposite the end of ouch tube and in line therewith is an opening in the header, closed by a, screw plug 19.
Between the units are placed vertical spin:- ing strips20 and surrounding the out ire condenser are two straps or ties 2.! Whose ends are connected by e bolt 22. 'lrensvcrse bolts 23 are passed through the ties end the spacing strips between the several lengths of the tubes, so that the Whole structure is firmly clamped together and will withstand the to which it is subjected in service.
The exhaust stemn is conducted into one end of the upper header and the water of condensation is conveyed away from the lower header to the tank.
For the purpose of cleaning the condenser, means are provided for ndu'iitting live steam into it. One way ol ell'ecting this is to connect the exhaust pipe with the steam muin by means of a short pi pe 2-1, provided with it stop valve 25; e check valve so being inserted in the exhaust pipe back of the point of l connection. By opening this stop valve the condenser cam be cleaned of Wltitl' at any time When thought nccesssry on stopping the carriage the boiler pressure may be reduced by blowing the steam into the condenser Where it will be condensed, without loss ol water. Should the cmidcnscr become clogged with oil or grease, it can be cleaned by live siezun in the l'ollowinp mnnnor: 'lwo ol' the screw plugs ll) nrc removed from the upper hendcr, and in place ol them are screwed in plugs 27, having the some thread as the others but provided with n cylindricul extension 28 adapted lo fit snugly into the end of the condenser tube, and serve u stopper hercl'or. The drip cocr 139 is then opened, or, if preferred, one of the screw plugs in the lower header corresprnnling to the plug ll) in the up )0! header is taken out. The live stcsm valve 25 is then opened nun the tube that is not shut oil by the cleaning plugs 27 can. be llmrougrhly blown out. By shifting the cleaning plugs one st n time, nil three tubes can be isolated successively and clesned, The entire oporation occupies bu t :1 few minutes, on d is not by any means so disagreeable as the method of cleaning by hand that is necessary in the case of condensers ol the ordinary construction.
