lo all 'wh/nu 'it muy concern.

it known that l, Groen Consrau Transen, a subject of the King of Roumanie., residing at London, in England, have invented a certain new and useful Improved VaporGenerator, of which the following is a specification. i

lhis invention; relates to generators of the surface or flash type, adapted for gen erating steam, and also for converting, into vapor, liquids other than water, for example liquid hydro-'carbon for carlmreting ypurposes.

The object of the invention is to provide a simple and compact apparatus of this type, havii'ig the advantage, among others, of being easy to build up and take to pieces, and also the advantage of a liquid-feed which is automatically regulated according to the requirements of the steam or vapor consuming apparatus.

it is an essential feature of the present invention that there is no access of air to the chamber, the liquid being fed into the f chainber against the pressure of the gen eraied vapor, and the invention 1s applied to au' cerbureting purposes, the vapor gen erated inust be mixed with the air outside the gencratin chamber.

@ne forni of construction of the improved Ivapor geninator, is illustrated in the accom-- panying drawing., in which if.' ure l is a longitudinal section of the appi "atus, with the central part broken away. Fig. 2 is an end elevation. viewed from the left hand side of Fig. l, and Figs. and l are sections on the lines A-B and lfb-D respectively of Fig.' l. Fig. 5 is a section corresponding to that in Fig. 3, but illustrating a inodiiication. end view, showing the vaporizer connected to a tank for the reception of nonvaporiz able constituents of the liquid fed to the vaporizing chamber.

in the drawing 2 represents the inner cylinder and 3 the outer cylinder, forming walls of an annular chamber, the cylinder 2 having at its right hand end a. flange l by means of which it is screwed into the cylinder 3. Al:- its left hand end the cylinder 2 has a flange 5 forming a seat for the cylinder 3,- the latter having at this end a ilange 6 bent to conform to the tiange 5. The flanges et and form the end Walls of the annular generating chamber between the cylinders 2 and 8. This generating cham ber can be heated by motor exhaust gases orfurnace gases passing through the cylinder 2, or a burner or furnace may be placed in the said cylinder 2.

The ilange 5 has four holes into which are screwed plugs 7, S, 9, l0. The plug 7 has a central bore through which a pipe ll passes into the upper part of the annular chamber, the joint being made tight by a nut 12 screwed. on to a projection of the plug. The pipe 1l is connected to a feed tank El() located above the generator and is closed at its right hand end, near the llango 4, and has lateral holes i3. This pipe 1l is the feed pipe through which liquid is sup plied to the annular cham'liie'r, the said liquid issuing through the holes 13. An eduction pipe la, for the vapor generated, passes through the plug 8 into the annular cham ber. rlhe hole into which the lplug l0 is screwed enables a second @duction pipe to be joined to 'the generator, if required. The hole closed by the plug 9 serves for the removal of mud or other non-vaporized inatter, for inst-ance the heavier constituents of a crude liquid hydrocarbon.

The cylinder 2 has longitudinal ribs l5 of such height as to nearly make contact with the cylinder 3. fact, be made larger than illustrated, so as to malte contact with the outer cylinder and absorb heat from the same, the-outer cylinder being heated in a manner wine.

will b e described hereinafter. 'The ribs have notches 15a. and the notches in the several. parallel. ribs are preferably disposed in staggered relation to each other; this can conveniently be done by cutting the notches by means of a helical cutting operation, performed around the circumference of the cylinder. The ribs l5 serve as aceumulators of heat, against. which the liquid iinpinges, the notches l5a enabling such liquid as is not directly flashed into vapor to pass freely down the sides of the chamber, over highly heated evaporating surfaces.

The feed is to a large extent automatically regulated in accordance with the requirements of the engine or other appara- 'tus served with the vapor, inasmuch as the pressure in the generating chamber, vary These ribs may, in

ing with thesaid requirements, automatically regulates the flow of liquid from thev 'holes 13.

Bolts 16 screwed into the flange 4 support a cover or head 1T some dlstance from the said flange. The bolts pass through bosses 18 which are integral with the head centric with the cylinders 2 and 3, the joints between the said ianges and cylinders 20,

21 being made tight by meansof packing.

, A tight jointis also made between the head 17 and the cylinder 21. The. cylinder 21 has holes 22 near the iange 6, and holes 23 outside the head 17, so thatheating gases issuing from the right hand end of the cylinder 2 are compelled to take a zigzag course through the cylinders 21, 20 before they can pass out of the apparatus through the p tice 24e surrounded by the flange 19. The cover head has an annular depression, as shown in section in Fig. 1, a-Hording a concavesurface where the heating gases strike it, so that the said gases, issuing fromv the cylinder 2, are deflected into the cylinder 21 with a minimum of obstruction by eddy action.

In the modifieationshown in Fig. 5, inwardly projecting ribs 25 on the outer cylin der of the generating chamber alternate with ribs on the inner cylinder. In this case the inner cylinder is not.' rotatable in the outer cylinder, and cannot be directly screwed into the same. The joint between the cylinders is accordingly made by other suitable means.

In `the construction shown in Fig. 6 a tank 26.provided with a cock is connected to the vaporizing chamber by pipes 2 7, 28, the connections being made at the holes which, in the arrangement shown in Figs.

V1 and 3, are closed by plugs 9 and 10. The tank serves forv the reception of non-vapor-A izable constituents of the liquid, which can be drawn olf fromtime to time.

I'prefer to construct the inner cylinder 2 of cast iron, except in designs of small pattern where copper or the like may be more convenient. The outer cylinder 3 is also preferably of cast iron, but may be of copper or the like. The cylinders 2() and 21 may be of copper or other sheetI metal.

It is notv essential that the heat absorbing bodies in the generating chamber are integral with. a wall or walls of the said chamber. Loose bodies may be insert-ed, but I prefer to have them integral in cases where a sedimentoccurs, rendering occasional cleaning' necessary;- in such cases it is convenient to be able to bodily withdraw the heat ,absorbing bodies, for cleaning purposes, together with the cylindrical walls of the generating chamber.
