GAS-ENGINE.

SPECIFICATION forming part of Letters'Patent No. 272,130, datedFebruary 13V, 1883.

Application tiled August 9, 1881. i (Model.) Patented in France May 16, 1881,

England July 16, 1881, No. 3,113,- in Italy July 23, 1881,

To all whom it may concern: l

Be it known that we, EUGNE ETVE and CHARLES CLMENT LALLEMENT, mechanical engineers, of Paris, in the Republic of France, have invented Yan Iinprovementin GasEn eines, (for which we have obtained Letters* Patent ot France for iifteen years, dated May 16, 1881, No. 142,877;) and We do hereby description thereof, reference being made to the accompanying drawings.

It is a known fact that gas-motors have the advantage that they dispense with fireplaces, with special attendance and wa-tchi'ulness, and that theyconsume fuel only when in actual use.' They are, however, inconvenient in requiring special and costly apparatuses for geution has been restricted almostentirely to large cities or towns.

Attempts have heretofore been made to burn hydrocarburets; but it was found that the feeding of the machines was at least as expenwere unsafe and liable to explode.

rlhe new motive-power engine which forms the object of our invention offers all the advantages of those Worked by gas, without their inconveniences, or those using hydrocarburets. It is of a simple and economical construction, very similar to that ot' a steam-engine.` It proed for operating it, and consequently cuts off its consumption as soon as'it stops.

The production of the hydrocarbureted liuid consists in `injecting a stream of compressed air into a recipient which contains any kind of hydrocarburets`such as petroleum, for instance, or any other equivalent material-and to mix this hydrocarburet with the compressed air within the cylinder, so that the mixture will be in the space adjoining the piston. An electrical spark causes the ignition of the contents, and its immediate expansion moves the piston, the power being still increased by in creasing the pressure of the air admitted. The quantity of hydrocarburet in each cylinder is very small-only enough to render the mixture inammable. The generator occupies but a small space and maybe easily removed from one place to another. All carea'nd watchful- No. 142,877; in Belgium May 18, 1881, No. 54,668,- in

ness may be dispensed with, as all its doings are automatic, so that the most-inexperienced hand may set it to work or stop it, as desired. The more the resistance increases the longer will the'inlet-ports for the hydrocarbureted air remain open, and consequently the combustion and the power of the'uiixture thus introduced will augment in the same proportion.

The drawings forming part of this specication are intended merely to demonstrate the application ot' the system of our new motor, and it is obvious that the general arrangements, as well as the new organs of this engine, may undergo such changes in form and construction as engines are usually subjected to.

Figure l is a side elevation. Fig. 2 is atop view partly in section. Fig. 3 is a vertical section across the cylinder.

The cylinder ais secured upon the bed b, which stands 4on legs b. The crank-shaft c, which rests in bearings that may be cast on the bed orjoined to it, is connected to the cross head p of the piston-rod p, which moves in guides e e. A iiy-'wheeh o, is'keyed on said shaft. The crank-shaft c, or the head of the connecting-rod, connects by suitable links or levers,lff2f3, with the piston ot' a suitable aircompressor, f4, of ordinary construction. The compressed air of the air compressor f4, by means ot' tube f5, is let to the generator g ot' hyuirocarbureted air, into which is poured either petroleum or any other equivalent hy drocarburets, and into which enter two tubes, the one, lc, leading to the upper, and the other, l, leading to the lower part oi' vessel g. rIhe pipe k is above the recipient g, divided into branches m m', (see Fig. 2,) that' end in the collector of the slide-valve t or distributor. The tube Z is in like manner divided into two branches, n a', that enter the same collector. The slide-valve t moves between two glass plates, 'i and j, the latter being fixed to the cylinder, close to its apertures r r', one ot'which is intended for the air and the other for the petroleum. The rod t2 of the slide-valve is conducted by one or two eccentrics of shaft c. The escapement is regulated by a second slidevalve, s, which is commanded by the eccen`- `tric s' on shaft c.

It remains to be explained how 4the engine ICO edges with two contacts nearly opposite each other. yyz, the one for theforward an d the other for the backward movements. These contacts are intended for pressing upon a commutator, A, with which one of the wires, F, is united, the other wire, F', ot' the magnet being in direct relation with an induction bobbin, B.

' This bobbin through wire sends back the iuid into'the bed b, and by a. second wire into another commutator, C, Fig. 2, which corresponds with a small disk, o, on shaft c. The disk ois made of hardened or vulcanized rubber, in which is enrolled a copper wire with two contacts, one for the forward and the other for the backward movement. Two wires, F3 F4, extend from the contacts of this disk o to the cylinders heads at the points G. The electro magnet might be replaced by a pile, but the induction-bobbin will distribute the electrical fluid all the same.

Functions of tzc-cttgi1ze.-For the starting it is necessary to impart to the fly-wheel sev'- eral rotations for the purpose ot' generating a small quantity of air under pressure. A stopcock on the pipe 7c acts upon the compressor 3o f4 and causes the generation to be without the aid ofthe hydrocarburet. It' we suppose that the piston is shown backward, then the slidevalve will show the corresponding openings, r r', so as to admit into the cylinder a. air under pressure and petroleum; but as a. consequence of the pressure ot' the air itself, and even of the aspiration by the piston, the hydrocarburet projects itselt' and pulverizes within the cylinder, and instantaneously and impalpably the Huid is mixing with the air. When arrived at the two-t'ths of the stroke of the piston the slide-valve shuts the openings, and .instantly one ot' the contacts of the pulley y presses upon the commutator A, which leads the magnetic tluid into the inductionbobbin, and at the same time the other commutator, C, generates the spark within the cylinder. The ignited gases expand and violently atentany push the piston ahead during the remaining' three-fths ofthe stroke. When the piston "makes its back motion the slide-valves opens the recess ot' the rear-f0r the purpose ot' exhausting the burned gases, while thedistribution is accomplished at the opposite face of the piston in the same way by the reversed working of the valvc't. After a few rotations the engine is started and does not require any l more care or watching. alice increases the speed of the piston diminishes, and the inlet-ports remain open for a greater length'ot' time, so as to admit-a larger quantity ofhydrocarburet and air, which causes a more powerful effect from every piston-stroke. After a few rotations the engine regulates its movement according to the resistance and worksregularly. The pressure ot'the air, which is to be admitted into the recipient ot' the hydrocarbnret, might be regulated so as to admit at any time such quantity ot' hydrocarburet as is desired to do the work at the time.

We claiml. The combination of the cylinder et and its piston with the shaft. c, air-compressing apparatus,f4, means, substantially as described, for operating said air-compressing apparatus, connection f5, mixing-chamber g, pipes 7i: and Z, slide-valve t, and spark-generating apparatus B C 0,'all arranged substantially as herein shown and described.

2. The combination ofthe cylinder t wit Athe magnet x, pulleys m and y, shaft c, com- Nalves,s and t, and with the inletpipes m,m,

n, and fn', and electric conductors F3 and F4, substantially as herein shown and described.
