SPECIFICATION forming part of Letters Patent No. 394,953, dated December 25, 1888.

Application filed March 23, 1888. Serial No. 268,298. (No model.)

Patented in Germany January 22, l 886,170. 35 9 9 3 in England February 13, 1886, 1102140; in Austria-Hungary, February 16 1886, No. 24,764 and No. 8,052; in France February 19, 1886,

To all /lm'my 'it 711/07/ cm1/c0771.:

`lie it known that we, OSCAR HRNLER, of the city, county, and State of New York, and EMIL CAPITAINE, of Berlin, S. 1V. Germany, 5 have invented' a new and Improved Hydrocarbon Motor, (for which I have' obtained Letters Patent in the following countries: Germany, No. 35,663, Januaryv 22, 1886; lelgium, No. 71,662, February 20, 1886; Franco Io No. 174,261, February l), 1886; Austria, No. 8,052, February 16, 1.886, Hungary, No. 24,764, February 16, 1886; England, No. 2,146, February 18, 1886,) of which the following is a speci'lieation, reference being had to the an- I5 nexed drawings, forming a part thereof, in

which- Figure l is a side sectional elevation. Fig. ll is a plan view.

Similar letters of reference indicate corre- 2o sponding parts in both the iigurcs.

This invention has referencel to motors which are worked by means of a mixture of air and finely-divided oil, or of air and tinely divided petroleum, or ol" air and finely-divided 25 nz'lplitha, and in which the air upon its admission into the (jylinder operates the line division of the oil or mrt-roleum or naphtha. The appliance Afor this operation has Vhitherto been arranged in the cylinder or in the cylimler- 3o cover, in which case the air entering the cylinder through the dividing or sprinkling appliance effects the line division of the oil,pe

troleum, ornaphtha, the cylinder at the same' ti me being filled with a misty vapor consisting 3 5 of a mixture of finely-divided oil, petroleum, or naphtha. A consulerable part of the ,tine oil, petroleum, or naphtha comes in contact with t-he cooled cylinder and piston surfaces lin the form of small particles and adheres 4o thereto. 1n the case where naphtha or other readily volatile hydrocarbon is employed to drive motors the contact of the small naphtha particles with the cylinder and piston surfaces is not prcjiulicial, because the naphtha read- 4 5 ily evaporates or gasiiies; but when d ifcultlyvolatilized hydrocarbons are employed for that purpose-as, for example, oil or petroleum-the contact of the oil or petroleum particles with the cooled cylinder and piston surfaces is very prejudicial, because they do 5o not immediately gasiify.

Our invention consists in an appliance arranged within the piston for dividing or sprinkling the oil, petroleum, or naphtha, as the case may bc. The air is caused to pass 5 5 with great velocity through the said appliance into the cylinder in the direction of the cylinder-cover.

A great advantage is obtained by the air and the iinely-divided oil, petroleum, or naph- 6o tha particles it carries along with it passing from the piston in the above direction. If the cyliluler-cover is not cooled, it reaches a temperature of from SOOO to 4.000 Celsius. l/Ve do not cool the cylinfler-cover. The finely- 65 divided oil, petrolemn, or naphtha which comes in contact with the hot cylinder-cover is at once g: sified. As the air and the finelydivided hydrocarbon passes Afrom the piston directly'toward the cylinder-cover, no wet pre- 7c cipitaton 'of oil, petroleum, or naphtlia takes place.

A is the foundath)1I-frame; B, the crankshaft; B', the crank; C, the cylinder; D, the piston; D', the sprinkling or atomizing appli- 75 ance for finely dividing the oil, petroleum, or naphtha. E is the exhaust-valve for the out-A let of the waste gases from the cylinder; F F, toothed wheels; F2, a cam for operating the exhaust-valve E, and G is a tube through 8o whichthe oil, petroleum, or naphtha is carri ed to the piston.

rlhe piston is in connection with the crankshaft by means of a connecting-rod in the usual way. 85

The sprinkling or atemizing appliance consists of the orifice d in the piston for the passage of air into the cylinder, and of the passage e for the oil, petroleum, or naphtha. The passage e being at right angles to the passage 9o d., the flap-valve 7c serves for closing the orice CZ, and the valve m closes the passage e. The diameter of the toothed wheel F on the crank-shaft is half that of the toothed wheel F', consequently only one revolution of the 95 toothed wheel F will take place for every two revolutions of the toothed wheel F. The action of the cam F2, carried by the toothed wheel l1", causes the valve .E to open at every second stroke of the piston, this heingett'eoted through the rod S, one end ot which is kept pressed against the periphery ot' the eam FL hy the spring S. '.lhe levers S C2, arranged at right angles to eaeh other on the same shaft, are eonneeted with the rod S and eonnnunieate motion to the exhaust-Valve E.

The wa)v in which the motor works is as iollows: As in the Case ol? ()ttos gas-motor, the Combustible mixture is drawn into the cylinder duringi the forward stroke of the. piston, compressed during the next following' backward stroke, during the next forward stroke the ignited gaseous mixture lis ex panded, and during the next following haekward stroke the products ot' eomlnistion ejected-that is to say, during` four pistoustrokes there oeoursan admission ot the combustible mixture, a compresion oi' this latter, an ignition ot' the eonlbi'lstihle mixture a n d ex.- pansion ot' the gases, and an ejection o1' the products ot' Combustion oi' the gases. rihe ail.' enters the eylinder through the .flap-Valve '/.1 and oriiiee (I, and simultaneously therewith petroleum enters from the Cavity in the bottoni ot' the piston through. the Valve fm and passage e, and is carried alongl with the airin a finely-divided state, owing Ain a great measure to the high velocity with whieh the air streams over the surlaee o t' th passa ge e. lhe

petroleum flows into the eavity iu the lower side ofthe piston through the tube G. As before stated, Vinsteul of petroiei'nn, oil, Anaphtha, or other hydroearlmn ma)v he used.

\Vhat we claim as our invention, and desire to seeure hy fl'ietters Patent, is-

1. ln oil, petroleum, naphtha, and similar motors, a piston provided with an atolnize'r t ior iinely dividing theoil, petroleum, naphtha, or other h ydroearlmn used in drivingl the same, sul)sta'tntially as deserihed and shown.

ln a hydroearlum motor, the :onrhination ot' the piston `l),pro\'idm'i 'with the oritees (I e, arranged at an angle with eaeh other, and the Valves /f/ `nl, arranged to elose the oritiees during1 the inward strokes oi the piston, suhstantially as herein speei fied.

2l. The eomlliiuation, with the pistons l), provided with an atomizine and an oil-eou tainin l Cavity, ot' the oil-si'iliply tuhe (i, sul)- stz'intially as spee'itied. i
