.heat for the initial vaporizingand the ultimate gasifying of the oil being derived from .the exhaust gas of the engine.

The present invention relates to an appa-A ratus of similar' type, but of an improved construction.

One of the main objects of the present invention is to heat the air to a' high degree beforeit is admittedA to the vaporizing mem-l ber, and another object of substantially vequal importance is to provide means for causing this heated air and the exhaust4 gas to be brought into more intimate contact' with'the oil on the vaporizing member and to also ex-y pose a greater area of oil in contact with the airV than is obtained by the apparatus in the previously described application, or by any other apparatus of which I am aware.

The accompanying drawings illustrate the invention and referring thereto :Mliigure 1 is a vertical cross section through the apparatus, showing it connected with the cylinder of'an explosive engine.' Fig. 2 is a vertical cross section through the apparatus on line :c2-x2 Fig. 1. Fig. 3 is a horizontal cross section through the apparatus on line @c3-'x3 Fig. 2. Fig. 4 is a view similar to Fig. 2 but partly, in elevation, illustrating another form of vaporizing member and flanges.' Fig. 5 is a horizontal cross section through the apparatus on line n35-zt? Fig. 1.

The apparatus comprises a base 1, having a cupped upper portion 2 withv an inwardly directed flange 3 forming a central circular opening 4. 4Mounted onv the cupped portion 2 is a dome 5 having flanges 6 which are detachably fastened to lange's 7 on the cupped portion 2 by thumb screws 8. The dome 5 is covered with a metal jacket 9 with an intervening asbestos heat insulation 10, The upper end of thefdome has a Alifting ring l1, and in order to determine the temperature Within the dome, a thermometer 12 may be inserted in the upper end of the dome, as shown in'Fig. 1.

Within the dome 5 nesting therewith is a cylindrical va orizing member 13, the lower edges of whic rest upon the flange 3. The upper wall of the vaporiz'ing member 13 is slanted, as -shown in Fig. 2. Preferably formed integrally with the vaporizing member 13 is a diametrical partition 0r web 14', the lower portion of which extends below the `cylindrical portion of the va orizingmember 13 into the base 1, divi ing the latter into two chambers 15 and 16. edge of the web 14 terminates short of theinclined upper wall of the vaporizing member, thus forming an opening 17 giving communication between the two chambers in the vaporizing member 13.

Preferably cast integrally withthe web or partition 14 is a conduit or pipe 1S, the upper end of which has an extension 19 which projects beyond the upper edge of the web 14 and through and beyond the upper inclined wa-ll oi thevaporizing member, as clearly shown in Figs. 1 and 2. The upper end of the. extension 19 terminates short oi the upper wall of the dome. The lower end of the conduit 18 has an extension 20 which projects through and below the base of the chamber 1 and is threaded for a nut 2.1, by means of which the conduit, web, and vaporizin member (all of which are integral) are rigidlgy held securely in position. A pipe 22 is connected to the threaded extension 2O for the purpose of conveying gas from the apparat'us to the cylinder 23 of the engine, the

pipe 22 connecting with a pipe 24, the lower end ofcthe latter connecting with an air inlet p1pe 25, having a valve 26 for regulating the `amount of air admitted to mix with the gas .which isconducted through the pipe 22 so that the proper mixture kof air and gas is, allowed to enter through the pipe 24'mto the 'cylinder Formed externally on the walls of the vaporizing member is a series of flanges 27. These flanges are preferably cast integrally with the vaporizing member and they' extend clear to the walls of the dome 5. Each flange is very slightly dished, as shown, and

' has a slightly raised lrim 2,8 which lies close to the wall ofthe dome 5. Each flange also has a segmental opening 29, as shown inFlg. 3. The flanges are arranged in two sets, one set' The upper loo slanting in one direction and the other set slanting in the opposite direction, as shown in Fig. 2. The openings 29 of one set of flanges are arranged next to one side wall, the openings29 of the other set arearranged diametrically opposite. There is thus avvertical tortuous passage for hot air upthrough the interior of the dome formed by the stag# gered openings 29, and for -thefdownward passage of oil formed by the slanting flanges.

At one side of the partition 14 the base 1 has an enlargement 31 which is closed by a plate 32, and a butterfly valve 33 isfarranged 1n this space to regulate the passage of exhaust gas from one chamber'to the other. The valvej 33 has a stein 34 which passes throu h a stufling-box 35 andy has a handle sprin 37 serves to frictionall hold the valve in t 'e position set.

15 from the chamber 16.

A pi 38 connects the chamber 15 with the cy Inder 23 and serves to conduct the exhaust from the cylinder to the chamber 15. A pipe 39' connects the chamber 16 Witlya T 40, t elatter .connecting with a verticaly ipe 41 lwhich dischar es the' exhaust gas rom the apparatus.4 lxtending ldown through the ipe 41 is an airint'ake .42,` the `lower end of w ich passes through the f1 40 and is connected by' ipipg- 43.v with the Ichamber 30, as shown in IPigs. 1, 2 and 5; The chamber 30 has a drainy pipe 44 provided with a valve 45.

An' oil pipe 46 extends up through the chamber 30 close a ainstV .the inside' ofthe dome v5 the flangeseing cut tripermit the passage of the p1 e, and the ipe `46 has-.a curved upper en 47 ada te to discharge the oil down'on the top ange as lshown 1n Fig. 2. The lowerend ofthe ipe46 is connected by a pipe 48 with a va ve 49, and in order to maintain-the proper lead of oil to insure its delivery from the upper end of the pipe 46, `alooped pipe 50 is provided, one run of which communicates with ythe valve 49. 50 and 51. desi nate the circuit terminals of the loop v5 'wl 'nch are'connected withthe oil supply source The loop 50 is always kept filled with oil, and the 'desired amount may be admitted to the pipes 48 and 46 by means of the valve 49. The oil which not admitted through the valve 49 passes up and down through the loop 50 into the overflow tank.

-ln operation the lexhaust gas from the cylinder 23 passes through the pipe 38 into the chamber 15 and, with the valve 33 closed, the exhaust gas passes up through the interior of the vaporizing member 13 on one sideofthe partition, through the openings 17 at the upper end and down on the other side of the artition into the chamber 16, thence through the pipe 39 into the T 40, thence up through the pipe 41 from which it discharges The va ve 33,.- when placed vertically, alines with the edge of the partition 1 4 and divides the chamber and surplus tank not shown.

. the opposite formed into a vapor or gas, the purer portion from 'the apparatus. If the valve 33 is fully opened, then the exhaust gas passes direct from the chamber 15 to the chamber 16 and thence into the pipe 41. haust gas which is admitted to the interior of the vaporizingf-a member depends upon the positionin whichthe valve 33 is set, and as stated, if the valvev is closed, all of the exhaust gas will pass up and down through the vaporizing member, while, if 'the valve 1s partia ly opened, only part of the exhaust gas will pass through the vaporizing member, the remainder passing directl into the chamber land thence outf'throug the ipe 41. Air is drawn through the pipe'42, wlliich lieswithin the pi e 43, into the pipe 18 and thence intol the@ amber 30. From the chamber 30 it.V asses u -into the lowermost chamber wit inthe ome 5 below the lowest lange, passes tothe opposite side of the vaporizin member, then u through the opening 29 ci the superposed ange into the next space; it

.then passes to the other side of the dome and asses u through the ropening 29 of the nextl lgher an e into the next space and so on back and orth, the air taking a tortuous -path back and forth across thespace `within the dome 5, but externally of the vapoiizing member, thus traversing each of the many chambers formed the ilange's and' then issues throu hv the to llange into the upper part of the orne. he air which is-drawn throu hthe pipe 42 becomes very-highly heate while traversing the pipe 41 through which the exhaust gas is escaping, and therefore this air, before it enters the interior of the dome, is extremely hot.

The oil which is admitted from the pipe 46 vdrops onto the upper flange and, iiowing around both sides o the conduit, falls down through the opening 29 onto the next lower flange, and the oil spreads out on this llange and flows in a reverse direction t`o the lower part oithe Afiange, then through the opening 29 of the ange onto the next succeeding sive chambers formed by the flanges. Any oil or residue which, during this passage, is not converted into gas, .drops into the chamber 30 from which it may be discharged from time to time through ipef44. The oil in taking this downwar tortuous passage s rea s t at a great areaof it is exposed to the irect action of the hot air whichis takin the same tortuous passabe, but which is wor ing u in direction, so that the oi is of which assemb es at the u per part of the dome 5, and this mixture o gas and heated air is drawn by the suction of the engine down through the pipe 19 through the pipe 22 intothe cylinder of the engine, and the gas in its downward passage through the pipe 18 is thus kept at ,the proper temperaout in a thin `film over `the lian es s o.

,iiange, and so ondown through the succesture, by reason of the additional heat which is imparted to it by| the heat of the exhaust gas which has a circuit up and down through the interior of th'e vaporizing member on both sides of the partition 14. i

I have found v1n practice that the hotair which rises from the chamber is alone suf,- icient to vaporize the oil, but by my construction as high a degree of heat may be ob? extended clear to the walls of the dome and form alarge number of communicating chambers whlclr cause the hot air to work its way by degrees to the top of the dome and thus come into contact with agreat area ofthe oil with which it is thus necessarily in contact for a considerable time causing it to impart as much of its heat as possible tothe oil to vaporize the same. The'flanges being large also cause the oil to be spread out thinly and to be exposed over a lgreat area to the action 4of the hot air, thus greatly promoting the efliciencyof the apparatus.

lf desired, the flanges may be made spirally, as shown in Fig. 4, in which case the heated air will have an upward helical travel, while the oil will have a downward helical travel,

` the action of the heated air on the oil being practically the same as in the previously 'described construction.

While the .helical flanges in this modificav tion formwhat might be termed a single continuous flange, and a continuous spiral chamber, just as the threads of a screw are sometimes referred to as the thread7 of the screw, l consider the construction to be the equivalent of the series of flanges of the previous form, and in the claims I use the term flanges as including the helical flanges as wellas the flanges of the previous form, and thus l consider the helical flanges as forming chambers which com'municate. the operation of the helical construction is substantially the same, and the .result obtained is substantially the same as in the previous form.

It is considered much preferable to per form the vaporization by theA heated air andr to admit only enough exhaust gas to the in-V terior of the vaporizer to keep ythe gas which has been formed by the heated air warm, thus obviating heating the metal too'high by the exhaust gas which causes lthe oil to carbonize and collect on the me t al By admitting Moreover only this amount of exhaust gas to the va orizer and relying substantially exclusively on the heated air for accomplishing the vaporiza'tion the oil does not carbonize and the apparatus is kthus kept very much cleaner than otherwise. t
