STARTING-G EAR FOR GAS-ENGINES.

Application filed February 4, 1889. Serial lio- 298,661. (No model.) Patented in France January 16, 1888, No. 188,161;in Italy February 18, 1888,110. 23,061; in England February 24, 1888, N0. Z,805;i11 Spain May 18, 1888,1io. 7,946, and in Belgium August 24, 1888, No. 83,003.

To all whom it may concern:

Be it known that we, EDOUARD DELAMARE DEBOUTTEVILLE, engineer, and LEON PAUL CHARLES MALANDIN, mechanician residing at Fontaine-le-Bourg, canton de Oleres, (Seine- Infrieure,) in the Republic of France, have invented Improvements in Starting-Gear for Gas-Engines, (for which we have obtained Letters Patent in France, No. 188,161, J anuary 16, 1888; Italy, No. 23,061, February 18, 1888; Great Britain, No. 2,805, February 24, 1888; Spain,No. 7 ,9i6,May 18,1888; Belgium, No. 83,003, August 24, 1888,) of which the following is a specification. I

The difficulty heretofore experienced in starting gas-engines, especially those of considerable power, has proved a serious obstacle to the general use of these engines in practice. Many special methods have been proposed with a View to facilitating the starting of the engines, but have not been found to work satisfactorily.

The present invention has for its object a new system of starting-gear applicable to gasengines. This starting-gear is illustrated in the figures on the annexed drawings, the same letters of reference indicating corresponding parts in all the figures.

Figure 1 of the accompanying drawings is an elevation partly in section, illustrating starting-gear arranged according to this invention and suitable for a motor of twentyfive horse-power, working with poor gas, for example. This view shows the admissionvalve box and gaschamber g. It also represents in dotted lines an ignitor J, which is connected with the gas-box g by a three-way cock it, connected to a branch 77. by means of a rubber tube '1'. Fig. 2 is a diagram illustrating the four periods or cycles of the engine, with the division for the explosion period, special starting division. Fig. 3 is an elevation of the three-way cock is, fitted onto the chamber of the ignitor j, which is shown in section in this figurewith the two insulated conducting-wires. The cock is, which should be as perpendicular as possible, should not exceed an angle of twenty degrees to work commutator or switch arrangement.

well. Fig. 4L shows the cook 71? in section. Fig. 5 isa view, in elevation, of the said cock. Fig. 6 is an end view, in elevation, of the induction or transformer coil. Fig. 7 is a plan of a Fig. 8 is a View of my improved starting-gear as independently applied to any gas-motor. Fig. 9 represents theworking-cylinder provided with a cook.

The motor being at rest, the fly-wheel is turned byhand so as to bring the connectingrod to the dead-point forward that is to say, to the point 0, Fig. 2. This point is where the explosion takes place when the engine is running. The strength of one man is enough to turn the fiy-wheel for the one or two necessary revolutions if the motor does not exceed twenty-five horse-power. For a motor exceeding this awinch or other suitable gear may be employed to turn the fly-wheel. When the connecting-rod is at the dead-point c, a gas-cock Z, placed on the valve-box g, Fig. 1, is opened in the ordinary position for starting. Then the three-way cock 7c is opened as indicated in Figs. 1, 3, 4, and 5. The flywheel then is turned so as to bring the connecting-rod a little beyond the angle of ninety degrees-i. e., approximately to the point e. The fly-wheel must be turned slowly in order to give the gaseous mixture time to fill the cylinder. The gas entering at 0, Figs. 3 and 4, mixes thoroughly with the air entering at 'nand penetrates to the ignition-chamber, and passes on into the working-cylinder of the motor. It must be understood that during this time the vibration of the hammer or contactmaker of the coil is stopped, so that the spark cannot pass between the two ends of the platinum wire. The three-way cock 7c is now shut, a small stop m preventing the key Z from turning through more than a quarter-turn. The fly-wheel is then turned backward to bring the connecting-rod in a position corresponding with the point e, a little in front of the position f, Fig. 2. This is done in order to slightly compress the mixture in the cylinder, thus facilitating ignition and giving a longer stroke to the connecting-rod at (No Model.) 3 Sheets-Sheet 1. O L. DIEOKMANN.
