UNITED STATES PATENT OFFICE. DONÁT BÁNKI AND JOHN CSONKA, OF BUDA-1'ESTII, AUSTRIA-HUNGARY. GASOLENE-MOTOR. SPECIFICATION forming part of Letters Patent No. 595,552, dated December 14, 1897. Appllcitlon Sled HoTember 30,1898. SirUl Ho. 811,020. Wo model.) To all whom, it may concern: Be it known that we, Dox.iT BANK! and JOHN CSONKA, subjects of the King of Hungary, residing in Bnda-Pesth, in the Kingdom 5 of Hungary, havo invented certain new and useful Improvements in Gasolene-Engines, of which Iho following is a specification. We have made improvements on gasolenemotors which in the main principle refer to IO tho manner of and means for introducing the gasolene into tho device for obtaining a sufficient mixture and to the construction of a combustion-chambor which accomplishes the combustion of tho mixture without tho help »5 of any exterior heating. Our invention is illustrated in the accompanying drawings, in which— Figuro 1 is a sido elevation of tho engine, partly in section. Fig. 2 is a section on lino lo 2 2 of Fig. 1. Figs. 3, 4, and 5 are views of different forms of reservoirs for maintaining tho gasolene-supply at n constant level, Fig. 3 being a section on lino 3 3 of Fig. 1. Fig. G is a longitudinal vortical sectiou of a modi15 fled form of tho feeding device. Fig. 7 is a transverse vertical section of the same. Figs. 8, 0, and 10 are modified forms of heating devices; and Figs. 11,12, and 13 are detail views showing modified forms of igniting devices. 30 Tho device for producing a combustible mixture, which for brevity we call the "feeding" device, is arranged in tho suction-tube before tho main valvo V, Fig. 1, Sheet I. This is arranged in such a way that during the 35 period of suction a certain quantity of fluid is sucked into tho air-pipo and drawn violently irtto tho cylinder. In tho wall of the air-pipo K is an opening Or passage F, which communicates with .1 tubo 40 or passage !*, loading to a gasolene-reservoir M, which is adapted to maintain tho gasolene at a uniform level. In Figs. 3, 1, and 5 thcro aro three dilTcreut Constructions Shown for the ro'gulnlluM of this 45 constant level of the liquid. In Fig. 3 is Shewn a float S in the liquid, anil connected with this flout is a small valve which may be elosod by the float as soon us tho sumo rises and opens again as soon ns the level of tho gasolene falls, lowering tho float. The play 5 of this float holds in this way {lie liquid in nearly cxactcoustant height. In Fig. 4, Sheet I, is shown an escape-pipe iu the level JI N, which does not allow a rise of the level. In Fig. 5 tho liquid is closed iu a vessel, and an 5 air-tube extends down therein to the line JI N, and thus there is a discharge-pressure on the liquid equal to the height Si h, tending to discharge tho liquid at the cock I'. In Fig. 7 is the level of the gasolene visible Si on a gage-tubo \V. In Figs. 0 and 7 is shown a modified arrangement of the feeding device,in which four openings F' aro provided in the chamber B, which communicate with the boring E'and gasolene- 6 tnbeP'. . The area of tho openings !•" is controllable by means of screws G, which end in. points of a conical form. These screws may bo provided with a central longitudinal boring II, 7. Figs.U and 7,through which air maybe sucked in during the period of suction, whereby a complete dispersion of the gasolene will result. The introduction of air may be regulated either by hand by means of a throttle-valve 7 D, Fig. 1, Sheet I, or else automatically by the suction of air. Such an automaticallyacting throttle-valve is shown in Fig. C. Tho lids D are kept closed by means of the spiral spring / and open only iu case there 8 should be a decrease of atmospheric prcssuro in chamber B, and iu proportion to this decrease of pressure in chamber B the lids consequently regulate the degree of diminution of pressure. 3 In box 15, Figs. C and 7, is a chamber C, through which the waste gases pass at K and I, in order to heat the explosive mixture. In order not to change tho mixture produced by means of our atomizer in thu cylin- 9 dor by condensation, so that the mixture remains easily iullammnblc and tho combustion-tube cannot be cooled through the contact with the mixture, we heat tho air which wo uso for feeding our engine. By tho heat- 9 ingof tho feed-air and thu uso of a couvenently-oonstrueted coinbusi ion-lube wo nttaiu this, that wo diaponso with a coutinuously6.a Bánki-Csonka patent description in the U.S.
